Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention concerns a protective sleeve for objects
according to the preamble of patent claim 1.
[0003] Such a protective sleeve is provided, for example, for the
packaging of knives, other sharp-edged objects, such as saws,
operating instruments, as well as tongs, and the like. Similarly, a
protective sleeve according to the invention is used for packaging
and storage as well as for protection against injuries from cutting
and thrusting weapons.
[0004] 2. Discussion of the Prior Art
[0005] In the prior art, it has only been previously known to form
a protective sleeve for such objects in such a way that there is a
protective sleeve open on one side, into the open front side
opening of which the object to be protected with its area to be
protected against grasping can be inserted.
[0006] In the case of a protective sleeve for the packaging of
knives or cutting and thrusting weapons, it is accordingly known to
insert the blade of the knife or the cutting and thrusting weapon
through the front side opening of the protective sleeve open on one
side in order thus to have the blade received on all sides in the
protective area of the protective sleeve. A known application is
the storage of cutting and thrusting weapons in a weapon
sheath.
[0007] The disadvantage of the previously known protective sleeves
open on one side, however, is that longitudinal movement is not
restrained. Another disadvantage is that the previously known
protective sleeves with low wall thickness also exhibit only low
mechanical stability because they do not exhibit any mechanical
reinforcements and the like whatsoever especially in the insertion
area. For this reason, there is also the danger that when the
object to be protected, especially a knife, is inserted, the upper
insertion area of the protective sleeve will be unintentionally
damaged.
[0008] Given the fact that with respect to the known protective
sleeves the object to be received there is not restrained as
protection against longitudinal movement, there is the additional
disadvantage that such protective sleeves cannot be hung vertically
on a display wall. There is also then the danger that the object
will slip out.
[0009] Although it is known in the prior art to attach
friction-increasing nubs or the like on the inside of the
protective sleeve that contact the surface of the object to be
protected, these friction-increasing nubs are insufficient if the
objects that are also supposed to be hung in a vertical position on
a display wall are heavy.
SUMMARY OF THE INVENTION
[0010] The invention is therefore based on the problem of further
developing a protective sleeve of the kind named above so that it
offers longitudinal restraint of the object to be received as
protection against longitudinal movement, that it is protected
against damage when the object is inserted, and that it is easier
to handle and more affordable to manufacture.
[0011] To solve the stated problem, the invention is characterized
by the technical teaching of claim 1.
[0012] Essential feature of the invention is that the protective
sleeve open on one side in a manner known per se now exhibits at
least a restraining area in which one or more restraining elements
are arranged that interact with assigned stop surfaces and/or
undercuts on the object to be held, and that the restraining area
is formed as an elastically deformable deformation area, upon
activation of which it is possible to disengage the restraining
elements arranged in the restraining area from assigned counter
elements on the object to be held.
[0013] This yields a completely novel kind of holder of an object
to be protected in a protective sleeve. Here it is presumed that
the object exhibits an area to be protected that is formed, for
example, as a blade or as a saw or as a tong element or the like
that is therefore received fully in the protective sleeve. This
hazard area is meant to be protected from grasping from the outside
because it entails a risk of injury or infection or even a
different danger.
[0014] Furthermore, connecting to this area of the object to be
protected is meant to be another area in which the counter elements
of the object to be protected are arranged that work together with
the assigned restraining elements on the side of the protective
sleeve, wherein connecting to these counter elements of the object
is a rear area that is a non-protective area and that forms, for
example, the handle of the object to be held or a clamping
thread--or more generally--a machine holder.
[0015] This then yields for the first time the possibility of
achieving a longitudinal restraint to be opened manually for an
object received in a protective sleeve.
[0016] In a preferred embodiment of the invention, it is provided
that the restraining elements arranged in the protective sleeve at
the upper free end are arranged in an elastic deformation area of
the protective sleeve so that, when the protective sleeve is
pressed together, these restraining elements are disengaged from
the assigned counter elements on the object.
[0017] But the invention is not limited to the restraining elements
in the restraining area of the protective sleeve being on the upper
free insertion end of the protective sleeve. They can be arranged
anywhere in the area of the protective sleeve with respect to their
longitudinal extension, and this also applies to the counter
elements on the object to be held, because not only must they be
arranged in the transition area between the non-protective area and
the protective area of the object, but these counter elements can
also be arranged in the protective area itself.
[0018] When reference is made in the present description to an
object to be protected in the embodiment of a knife with a sharp
edge, then the invention is not limited to this. All objects can
form the content of the protective sleeve in so far as they satisfy
the previously named and later named features.
[0019] In addition to the previously named objects, all other
objects can also be received to which packaging is assigned that is
meant to protect the object. Here it is not absolutely necessary
that the object exhibit a protective area. For example, tongs,
scissors, and the like can be received without the protection of
the tong or scissor part being relevant.
[0020] It is important with respect to the invention that the
protective sleeve offers an effective protection against injuries
because it is then no longer readily possible to extract the object
to be protected from the protective sleeve. Here manual force must
be applied in order to activate the restraining area, which
according to the invention is formed as an elastically deformable
deformation area in order to activate the opposing walls of the
protective sleeve in the deformation area with the restraining
elements arranged there so that the distance between the
restraining elements increases and they therefore disengage from
the counter elements arranged on the object.
[0021] The invention naturally also protects the kinematic reversal
of the locking principle according to the invention:
[0022] According to the above description, it was stated that
restraining elements opposing each other on the inside of the
protective sleeve in the deformation area and opposingly aligned
are arranged that are preferably formed as nubs, ribs, or other
projections.
[0023] But the invention is not limited to the arrangement of
restraining elements opposing each other and aligned with each
other. It can also be provided that such a restraining element is
arranged only on one side in the deformation area, while the
opposing wall is smooth and does not bear any restraining
element.
[0024] Applicable to both embodiments is also the kinematic
reversal according to the present invention, which provides that
there are recesses in each case facing outward or other bulges
projecting outward in the sidewalls parallel to each other, and
that on the object to be held are now provided projecting counter
elements that engage the protective sleeve-side curvatures and
there restrain the object to be held.
[0025] Likewise, the two kinematic embodiments, which have been
pictured as a reversal, can also be arranged in the one type on the
one side of the sidewall of the protective sleeve in the
deformation area, while the kinematic reversal of the restraining
elements is arranged on the opposing side.
[0026] With the arrangement of the restraining elements on the at
least one side of the deformation area as bulges of the protective
sleeve and on the opposing side as inward facing nubs, this also
yields insertion protection in such manner that the object to be
held can be inserted only in a specified insertion position while
it cannot be held in an insertion position rotated by
180.degree..
[0027] In a further development of the invention, it is provided
that the end of the object, which is formed as a non-protective
area and which exhibits, for example, a handle, a tool holder, a
clamping holder, or the like, can also b closed with a protective
cap. This protective cap is then likewise open on one side and is
pushed over the end of the object to be held, namely via the
non-protective area, and can arbitrarily be engaged with the
rearward open end of the protective sleeve. Push-on connections or
latching connections or rotating connections or the like are
possible here.
[0028] With the use of a protective cap that can be pushed,
latched, or screwed onto the rear free and open end of the
protective sleeve, there is the additional advantage that this area
can be sealed so that there is a hermetically sealed protective
packaging.
[0029] The invention is not limited to the profile forms of a
protective sleeve shown in drawings here and a protective cap that
might be combinable with it. The profile forms of the protective
sleeve represented here mainly refer to an approximately
rectangular, oval, or polygonal profile form of the protective
sleeve. The invention is not limited to this. The protective sleeve
can also be formed as a roundly profiled protective sleeve, wherein
the profile forms can deviate from one another in different areas
of the protective sleeve. For example, the protective area of the
protective sleeve in which the part of the object to be protected
is received exhibits a different profile form from comparatively
the profile form of the restraining area that is formed as a
deformation area.
[0030] Furthermore, connecting to the deformation area, which is
preferably arranged in the area of the front side opening of the
protective sleeve can be additional sections of the protective
sleeve that can be profiled in any manner and that are especially
well-suited for receiving a protective cap to be pushed, latched,
or screwed onto this area.
[0031] If, for example, a round profile area is connected to the
deformation area of the protective sleeve, then the protective cap
to be pushed or screwed onto it likewise can be roundly profiled
and bear a suitable thread.
[0032] An additional embodiment concerns a protective sleeve
consisting of two half shells that are connectable to each other
along a parting plane running in longitudinal direction of the
object to be packaged. The two half shells can be formed in mirror
symmetry to each other.
[0033] In another configuration, however, the profile of the one
half shell can deviate from the profile of the other half
shell.
[0034] The two half shells can be fully separable from each other
in a first embodiment and in that case they are combined by
edge-side latching connections arranged between the half shells
into a complete protective packaging.
[0035] In another configuration, the two half shells, however, can
be arranged pivotably to each other on a longitudinal side through
one or more film hinges. To close the protective packaging, the two
half shells are then therefore pivoted against each other into a
closing position along their longitudinal pivoting axis. The
closing position is then restrained and secured between the two
half shells by a latching opposing the film hinge and preferably
likewise arranged on the edge-side.
[0036] The subject matter of the present invention is evident not
only from the subject matter of the individual patent claims, but
also from the combination of the individual patent claims with each
other.
[0037] All information and features disclosed in the documents,
including the summary, especially the spatial configuration
represented in the drawings, are claimed as essential to the
invention to the extent that they are novel compared to the prior
art individually or in combination.
[0038] To the extent that individual objects are designated as
"essential to the invention" or "important," this does not mean
that these objects must necessarily form the subject matter of an
independent claim. This is solely determined by the respectively
valid version of the independent patent claim.
[0039] The invention will be further explained below by means of
drawings representing merely one way of execution. Additional
features and advantages of the invention essential to the invention
proceed here from the drawings and their description.

DESCRIPTION OF A PRESENTLY PREFERRED EMBODIMENT
[0068] FIGS. 1 and 2 show the basic principle of the protective
sleeve, which can be modified in many different ways. The
protective sleeve 1 according to FIG. 1 essentially consists of two
sidewalls 2 opposing each other and preferably parallel to each
other, which between them form a receiving space for an object 10
to be received, wherein the two sidewalls 2 are connected to each
other on the front side by longitudinal front walls 8, and the end
of the protective sleeve 1 is sealed by a front wall 3. The
protective sleeve is formed preferably as a blow molding part or as
an injection molding part, so that all wall parts of the protective
sleeve are connected to each other preferably in a single piece of
material.
[0069] But in a different configuration it can consist of parts
subsequently combined with each other. For example, the sidewalls 2
could have been connected to the separate longitudinal front walls
8 via an adhesive, welding, or latching method.
[0070] The invention is not limited to a protective sleeve 1 sealed
on the front side. The front wall 3 can also be eliminated and it
can be profiled in any manner.
[0071] At the opposing side to the front wall 3, the protective
sleeve 1 forms a front side opening 4, which is provided as an
insertion opening for an object 10 to be inserted there.
[0072] The protective sleeve is subdivided into various areas. The
larger and longer area of the protective sleeve serves to receive
the object 10, specifically to receive a hazard area 11 to be
protected, which is therefore inserted into the protective sleeve 1
via the front side opening 4.
[0073] In a preferred embodiment, the protective sleeve 1 in the
area of its front side opening 4 exhibits a restraining area 5, in
the area of which at least one restraining element 9 is arranged
that interacts with assigned counter elements 13, 14 on the object
10.
[0074] In the following description of figures, it is assumed that
the restraining elements 9 are formed as inward facing nub, ribs,
or similar restraining elements aligned with each other and
opposing each other.
[0075] In the general description, however, it has already been
indicated that it is sufficient to use only a single restraining
element 9 on a sidewall that interacts with an assigned counter
element 13 or 14 on the object 10.
[0076] In the kinematic reversal, it is likewise possible that the
nub-type restraining elements 9 formed as inward facing and
opposingly aligned with each other are now formed as outward facing
curvatures, wherein in turn only a single, outward facing curvature
is sufficient that works together with an assigned counter element
13, 14, wherein in that case the counter element is then formed as
an outwardly projecting nub on the object 10.
[0077] The restraining area 5 is formed as a deformation area 31,
by elastic deformation of which the restraining elements 9 can be
disengaged from the counter elements 13, 14 on the object 10.
[0078] It is represented in the drawing only in schematic form that
the restraining area 5, which at the same time forms the
deformation area 31, is arranged in the proximity of the open front
side opening 4. The invention is not limited to this. The
restraining area 5 can also be arranged, for example, in the center
area of the protective sleeve 1, as a result of which the front
side opening 4 then becomes longer and therefore also the insertion
area.
[0079] Accordingly, the locking area 12 on the object 10 must
then--corresponding to the restraining area 5 of the protective
sleeve 1--also correspond to the restraining area 5 moved in
longitudinal direction.
[0080] FIGS. 1 and 2 also show that, when the object 10 is received
in the protective sleeve 1, the right end of the protective sleeve
1 is closable through a protective cap 6, wherein the protective
cap is detachably connectable to the protective sleeve in any
manner It is to be fastened such that it can be pushed, latched,
welded, adhered, or screwed onto the protective sleeve 1.
[0081] The protective cap 6 is therefore pushed, screwed, or
latched onto the front side opening 4 of the protective sleeve 1 in
arrow direction 7.
[0082] The invention leaves it completely open what profile form
the protective sleeve is formed in. For instance, the area in which
the object 10 engages its area 11 to be protected can be profiled
rectangularly, ovally, roundly, or polygonally or formed in any
other different shape.
[0083] This also applies to the restraining area 5, the profile
form of which can be configured in any manner, which therefore
likewise can be formed rectangularly, polygonally, quadratically,
or roundly.
[0084] The protective cap 6, which is possibly to be pushed on or
latched on, is then adapted to the profile form in the area of the
front side opening 4 of the protective sleeve 1.
[0085] As a rule, the use of a protective cap 6 is not necessary.
The non-protective area 15 of an object 10 to be held would then
project from the right end of the protective sleeve 1 and does not
need any further protection.
[0086] This is preferred especially with respect to the packaging
of knives and similar objects, such as cutting and thrusting
weapons, because the user can then examine the knife handle and
assess the material of the knife handle.
[0087] Likewise, the innovative protective sleeve provides the
possibility of packaging in the protective sleeve sensitive tools
and the like, the receiving end of which freely projects from the
rear end of the protective sleeve. In this way, it is likewise
possible to insert the tool to be protected together with the
protective sleeve into a receiving area of a tool machine or
generally into a holder, and only when the tool has been fastened
in the receiving area can the protective sleeve be removed from the
item to be protected by manipulating the deformation area 31.
[0088] With the protective sleeve according to the invention, there
is therefore the possibility of mounting objects to be protected on
receiving areas of machines.
[0089] In FIG. 3, a side view of the protective sleeve with a knife
20 is shown that has not yet been fully inserted into the
protective sleeve 1 in the insertion direction (arrow direction
25).
[0090] The knife consists of a blade 21, which is to be protected
against grasping and which represents the area 11 to be protected,
and further a handle 22 connecting to the blade 21, which handle
defines the non-protective area 15 of the object.
[0091] The knife is therefore inserted into the front side opening
4 of the protective sleeve 1 in arrow direction 25, wherein in the
shown embodiment the handle 22 at its front end exhibits an
inclined plane 23 and a finger guard 26 connecting to the inclined
plane, which finger guard prevents the hand enclosing the handle 22
from slipping forward onto the blade 21.
[0092] Behind the finger guard 26, an undercut is arranged that
functions as counter element 13, 14 within the meaning of FIGS. 1
and 2.
[0093] In the area of the protective sleeve 1, there are in the
area of the opposing sidewalls two opposing centering nubs 18, the
functioning of which will be explained by means of FIG. 12.
[0094] Furthermore, the protective sleeve 1 is sealed on the front
side and exhibits a push-through protection 17, which will be
explained by means of the later FIG. 10.
[0095] Furthermore, on the other side of the deformation area 31 on
the protective sleeve 1 there is provided a stop wall that
interacts with the inclined plane 23 on the handle 22.
[0096] The stop surface was also shown in FIG. 1 and interacts
there with an assigned stop surface 30 on the object 10 to be
protected, as shown in FIG. 2.
[0097] With the interaction of these two stop areas, a secure stop
limit of the object 10 to be held is therefore guaranteed in the
protective sleeve 1, and the object 10 to be protected is prevented
from being inserted too far into the protective sleeve 1 in
longitudinal direction.
[0098] The function of this stop wall will be further explained
below in FIG. 13.
[0099] It is important in any case that this stop wall 19 is
adapted to the profile form of the front side of the handle 22 so
that the two stop surfaces 19, 23 are flush with each other and are
highly load-transmitting.
[0100] Naturally, the adaptation in other cases of an object is
different, for instance, the stop wall can be formed straight, and
in FIG. 1 a straight surface 23 is drawn in that interacts with an
assigned stop surface 30 of a general object 10.
[0101] The advantage of the arrangement of such a stop wall is that
as a result the front-side end of the protective sleeve 1 is
reinforced, and therefore there is a delimiting or partitioning of
the insertion area of the protective sleeve toward the deformation
area 31 on the rear end of the front side opening 4.
[0102] To the left of the stop wall 19, the protective sleeve 1
therefore is preferably not deformable or is formed from a
relatively non-deformable plastic material while to the right of
the stop wall 19 a deformation area 31 is provided for which the
deformation 31 is then deformed by finger pressure in arrow
direction 33 (see FIG. 4) so that the two opposing restraining nubs
27 detach from each other (see the arrow directions in FIG. 4) and
the previous restraining contour 16 in the deformation area 31
deforms into a widened restraining contour 16' so that the two
opposing and aligned restraining nubs 27 are disengaged from the
undercut 24 on the handle 22 of the knife 20.
[0103] FIG. 4 shows the insertion motion of the knife 20 upon
overcoming the deformation area 31. It is shown that the undercut
24 by itself thanks to the insertion force in arrow direction 25
performs the deformation in the restraining area 5, and therefore
the previously roughly rectangular restraining contour 16 widens in
an arch, as shown in FIG. 4, in order thus to remove the two
opposing restraining nubs 27 from each other and to disengage the
undercut 24 on the handle.
[0104] FIG. 5, by contrast, shows the secured insertion position of
the knife 20 in the protective sleeve 1, where it can be seen that
the finger guard 26 has now overcome the restraining nub 27 and
sits under the restraining nub 27, so that the restraining nub 27
in the area of the undercut 24 makes contact and therefore there is
absolute security against longitudinal movement of the knife 20 in
the protective sleeve 1 according to FIG. 5.
[0105] FIG. 6 shows the locked insertion position of the knife 20
according to FIG. 5. It can further be seen that the handle-side
inclined plane 23 then contacts the protective sleeve-side stop
wall 19 and an effective security against longitudinal movement
results. The tip 28 of the knife preferably has a certain distance
29 from a push-through protection 17 arranged there.
[0106] FIG. 7 then shows the mechanical deformation of the
deformation area 31 of the protective sleeve 1 in the restraining
area 5.
[0107] If, by finger pressure or by machine, pressure is applied on
both sides in arrow direction 33 against assigned surfaces in the
deformation area 31 to protective sleeve 1, the previous, roughly
rectangular restraining contour 16 changes to a bulging restraining
contour 16', and the restraining nubs 27 aligned and opposing each
other on the inside of the restraining contour 16 in the
restraining area 5 take their spread position following arrow
direction 34 according to 27'. Therefore the object to be held can
be readily extracted from the protective sleeve.
[0108] As an example of possible wall strengths, FIG. 8 shows that
pressure on the opposing longitudinal front walls 8 must be enough
for the opposing sidewalls 2 to bulge in the manner according to
FIG. 7.
[0109] The invention is not limited to this. Instead of applying
pressure in the arrow directions 33, it is sufficient to apply
asymmetrical pressure, wherein, for example, the diametrically
opposing transition edges between the longitudinal front wall 8 and
the assigned sidewall 2 are pressed.
[0110] It is sufficient to apply pressure in arrow direction 33
only from one side if the opposing side sits on an assigned stop
surface.
[0111] The invention is not limited to the profile form shown here
of the sidewalls 2 and the longitudinal front walls 8 connecting to
it. The sidewalls can also form an S-shaped contour--at least in
the deformation area 31--to enable an even better bulging in the
form of the restraining contour 16' according to FIG. 7. Such an
S-shaped contour has the advantage that with relatively low finger
pressure a very large deformation width is possible proceeding from
the restraining contour 16 up to the restraining contour 16'.
[0112] FIG. 9 shows merely as an example that in the deformation
area 31 opposing handle recesses 32 are provided that are meant to
indicate haptically that the deformation area 31 can be deformed in
the manner according to FIG. 7 by finger pressure on the two
opposing handle recesses (see also FIG. 11).
[0113] FIG. 10 shows the so-called push-through protection 17. It
consists of two opposing and connected rib areas that are welded in
the contact area and therefore form a stable counter surface at the
tip 28 of the blade 21.
[0114] The handle recesses 32 can also have a suitable,
handle-friendly surface structure 35.
[0115] FIG. 12 also shows that in the area of the protective sleeve
there can be opposing and facing centering nubs 18 that contact
both sides of the flat sides of the object to be held, especially
the blade 21 in order thus to hold the blade centered in the area
of the protective sleeve 1. In other embodiments, however, these
centering nubs 18 can also be eliminated or there can also be
several of them.
[0116] The centering nubs 18 can exhibit any designs; they can also
be rib-shaped.
[0117] FIG. 13 shows the insertion position of the handle 22 into
the front side opening 4 of the protective sleeve 1 and generally
shows the protective sleeve-side stop wall 19 contacting the
knife-side inclined plane 23. Therefore, the object to be held is
secured in longitudinal direction reliably and in a highly
loaded-transmitting manner
[0118] FIGS. 14a-14g show in top view and in cross-section various
embodiments of nubs 27 that are therefore designated according to
their embodiment with lowercase letters a to g.
[0119] The top picture in each case is the top view of the
respective nub 27, and the bottom picture is the profile form of
the same nub.
[0120] Every nub 27a-27g exhibits preferably an insertion bevel 37
by which the object 10 to be held can be slightly moved, and if it
is in its locked position, an assigned stop surface 38, which is
preferably bent or inclined, is meant to contact the object 10 so
that it can be withdrawn from the nub 27 only with difficulty by
overcoming this stop surface 38.
[0121] Furthermore, FIG. 14a shows a roughly quadratic nub with a
wedge profile, while FIG. 14b shows an oval nub with an airfoil
profile, while FIG. 14c shows a teardrop-shaped nub in the top view
and likewise an airfoil principle, while FIG. 14d shows an oval nub
with a half-round profile, while FIG. 14e shows a round nub with
likewise an airfoil principle, while FIG. 14f shows an inclined
oval nub with an airfoil profile, and FIG. 14g shows an inclined,
curved nub with likewise an airfoil profile.
[0122] FIG. 15 shows as security against removal and as antitheft
protection the use of an adhesive label 36, which serves as
manipulation security. The adhesive label 36 is adhered on the side
to the front side opening 4 of the protective sleeve 1 and likewise
to the handle 22 in order to identify an undesired removal of the
knife 20. If the knife 20 is removed, the adhesive label 36 is
destroyed.
[0123] It is merely shown in the interests of simplicity that the
adhesive label 36 is adhered to one of the sidewalls 2 of the
protective sleeve 1. In another configuration, one or more such
adhesive labels 36 can also be adhered to one or more of the
longitudinal front walls 8 or on other places.
[0124] The adhesive labels 36 can also be sleeve-shaped.
[0125] FIGS. 16 to 18 show different profile forms of the profile
of the protective sleeve at least in the deformation area 31. It
has already been shown by means of the general FIGS. 1 and 2 that
the profile of the protective sleeve 1 on the other side of the
deformation area 31 can also deviate from the profile in the
deformation area.
[0126] Therefore, FIG. 16 shows only a roughly rectangular profile
16A, which is converted into an arched profile 16A' when the two
opposing longitudinal front walls 8 of the protective sleeve 1 in
the deformation area 31 are pressed together by suitable
pressure.
[0127] Deviating from this, FIG. 17 shows that at least the
deformation area 31 can be oval, and therefore form a restraining
contour 16b that can be converted into a widened oval form of a
restraining contour 16b' in the arrow directions 33 by finger
pressure.
[0128] FIG. 18 shows that at least the restraining contour 16c is
formed from a multiple polygonal cross-section that is formed
preferably symmetrically, and upon pressure on the suitable,
opposing longitudinal front sides of this restraining contour 16c
the restraining contour is converted into the restraining contour
16c' shown in drawn-out lines.
[0129] FIGS. 19 and 20 show further examples of the holding of
objects in a protective sleeve 1. The protective sleeve 1 a shown
there is suitable for receiving, for example, scissors, which is
generally designated as object 10a.
[0130] Characterizing this type of protective sleeve is the fact
that the deformation area 31 directly connects to the insertion
area, and that in the insertion area (deformation area 31) two
parallel and adjacent restraining nubs 27a, 27b are arranged that
engage the assigned handle openings of the scissors and therefore
secure the scissors against removal from the protective sleeve
1.
[0131] Only when the protective sleeve is elastically deformed by
finger pressure in the arrow directions 33 on the deformation area
31 do the aligned and opposing restraining nubs 27a, 27b arranged
in pairs detach from each other, and as a result the scissors can
be easily removed from the protective sleeve 1.
[0132] Moreover, all other features that were described in
conjunction with the previous FIGS. 1 to 18 also apply to the
present embodiment according to FIGS. 19, 20 to 23.
[0133] FIG. 20 shows as a further embodiment that it is not
absolutely necessary to apply the deformation work in the
deformation area 31 by manual force in arrow direction 33. It is
shown that with respect to the holding of tongs the tong halves
themselves can be pressed together in arrow direction 33 as a
result of which in the center area between the tong halves the
opposing restraining nubs 27 are pressed together, the protective
sleeve 1 is thereby spread apart, and therefore the tongs can be
removed from the protective sleeve 1 when the handles are pressed
together.
[0134] It has already been emphasized that instead of opposing nubs
27, 27a, 27b, and 27c it is also sufficient to arrange such a nub
only on one wall of the protective sleeve 1. This also applies
especially to an embodiment according to FIGS. 19 and 20.
[0135] FIGS. 21 and 22 show a flat object 10c, which, for example,
is formed as a medical knife, as a saw, or generally as a medical
instrument that exhibits on its back side a receiving area 39 with
which this object 10c can be clamped in a receiving device. Here as
well the object 10c exhibits undercuts that are formed as counter
elements 13, and these undercuts work together with the assigned
restraining nubs 27 in the sidewall of the protective sleeve 1.
[0136] In the vertical plane to the parts 13, 27 engaging each
other in the security position there are opposing handle curvatures
40 on the protective sleeve 1 in the area of the sidewall 2, which
curvatures project beyond the surface of the respective sidewall 2
and when they are pressed together there is a material extension of
the sidewall 2 so that the sidewall 2 deforms in the deformation
area as is shown in FIG. 22. Therefore, the protective sleeve-side
restraining nubs 27 disengage from the object-side undercuts in the
manner of counter elements 13, and the object can be removed with
its receiving area 39 from the protective sleeve 1c.
[0137] FIG. 23 shows a cross-section through the object to be held
10c in the area of the counter elements 13.
[0138] FIGS. 24 to 27 show another embodiment of a protective
sleeve for which the same parts have the same reference
numbers.
[0139] FIG. 24 shows a perspective representation of a first
embodiment of a protective sleeve that essentially consists of two
latchingly connectable half shells 1d-1d.
[0140] In the embodiment according to FIG. 26 it is shown that
these two half shells 1d-1d are formed in mirror symmetry.
[0141] In the embodiment according to FIG. 27 it is shown that such
half shells 1e-1f can be formed in non-mirror symmetry.
[0142] In the perspective representation according to FIG. 24, a
total of two different embodiments are drawn in for both of which
separate protection is claimed.
[0143] The first embodiment refers to FIG. 24 in conjunction with
FIGS. 26 and 27 and concerns the fact that the two half shells
1d-1d and 1e-1f are completely detachable from each other and are
not connected to each other by any connecting means in the open
state.
[0144] Edge-side latching connections are provided as connecting
means for the two half shells, which accordingly exhibit a parting
plane continuous in longitudinal direction.
[0145] According to FIG. 24, there are latching connections both on
the upper longitudinal edges as well as the lower longitudinal
edges of the half shells 1d, 1d assigned to each other.
[0146] The latching connections are arranged by mutual distance
from each other, and each latching connection in the embodiment
consists of a latching lobe 41, which exhibits a rear facing
latching lip that engages an assigned, opposing recess in which a
latching bar 42 is arranged, one surface of which is inclined in
order to be engaged in the by the inclined, rear facing latching
lobes.
[0147] Because the latching lobe 41 is formed flexibly, the
latching connection can be easily released by pressing on the
packaging.
[0148] The same latching connections are also formed on the lower
longitudinal edge of the two half shells.
[0149] FIG. 24 therefore shows that the two half shells 1d-1d or
1e-1f are completely separated from each other in the released
state and are latchingly connectable to each other only in the area
of a parting plane 47.
[0150] In the embodiment according to FIG. 24, however, a second
embodiment is also drawn in that nevertheless is indicated only by
drawing. It is stated there that in the area of a lower
longitudinal edge 43 there can be a film edge 46 that appears
piecewise or extends over the entire longitudinal edge 43, so that
the two half shells 1d-1d or 1e-1f are pivotably connected to each
other in the area of the longitudinal edge 43 and are pivoted with
each other in arrow direction 45 and are latchable with each other
through the previously named latching connections 41, 42.
[0151] Characterizing all embodiments is the fact that the
deformation area 31 according to the invention is present even with
these embodiments in order thus to enable easy opening of the
packaging.
[0152] Opening is achieved according to FIG. 24 by pivoting apart
in the counter direction to the arrow direction 45 or--in the other
embodiment--the two half shells are pressed against each other in
arrow direction 44 in order thus to engage the latching connections
41, 42 assigned to each other.
