Abstract
A security seal having a flexible strip intended to be
piercingly inserted through at least one opening of an article
which is to be sealed, both ends of the strip after having been
flexed over upon themselves being non-releasably connected with one
another. To that end the flexible strip is provided at one end with
at least a portion of a closure and at its other end either with
the other portion of the closure or carries an element which can be
engaged with the closure. The one closure portion of the aforesaid
closure forms a container or receiver, at the base of which there
protrudes a head constructed as a catch element and the other
closure portion is formed by a plate which fits in the form of a
cover in such container and has a locking element in the form of a
recess into which extends shoulder means which, during closing of
the seal and pressing of the head into such recess engages behind
such head and in its inserted position non-releasably fixes
same.

Description
BACKGROUND OF THE INVENTION
The present invention relates to a new and improved construction of
security seal or security marker which is of the type incorporating
a flexible strip intended to be piercingly inserted through an
opening or number of openings of the article or object which is to
be thusly sealed, the strip, after having been bent over upon
itself, should have both ends of such bent-over strip
non-releasably connected with one another.
Prior art constructions of security seals of this general type
oftentimes consist of a number of components and are expensive to
fabricate. A number of such seals require a tool in order that they
can be closed; other prior art seal constructions heretofore known
do not eliminate the possibility of undesired tampering or
manipulations.
A seal of this species is known to the art wherein a sheet metal
strip is drawn through the opening or openings of the article which
is to be sealed, and after the sheet metal strip is flexed over
upon itself it can be riveted at both of its ends by tongs or
pliers. The rivet location is subsequently covered with a plastic
cap. With this prior art construction of seal there is present the
drawback that riveting of the sheet metal strip is not undertaken
in a completely faultless manner and tampering or manipulations for
the purpose of providing a false seal or giving the appearance that
the article has in fact been sealed is possible.
According to another state-of-the-art construction of seal of the
previously mentioned type, both ends of the flexible strip have
associated therewith rather bulky closure elements. Consequently,
this construction of seal cannot be employed in those instances in
which the opening or openings of the article to be sealed is small,
especially in conjunction with slot-shaped openings. Further, with
this construction of seal the catch element and the locking
element, even when the seal is closed, are freely accessible so
that it is easy to provide a false or improper seal at the
article.
SUMMARY OF THE INVENTION
Hence, from what has been explained above it should be apparent
that the prior art is still in need of security seals which are not
associated with the aforementioned drawbacks and limitations. It is
therefore a primary object of the instant invention to provide a
security seal which effectively and reliably fulfills the existing
need in the art.
Another and more specific object of the present invention relates
to a new and improved construction of security seal which, while
retaining all of the advantages of the heretofore known
constructions of such seals of the previously mentioned type, still
can be easily connected and closed without the need of a tool, no
longer can be opened without permanent damage to the seal, is
relatively inexpensive to manufacture, and indicates both optically
as well as acoustically proper closing of the seal.
Now, in order to implement these and still further objects of the
invention, which will become more readily apparent as the
description proceeds, the security seal of this development
embodies a flexible strip intended to be piercingly inserted
through an opening or number of openings of the article or object
to be sealed and both ends of the strip, after folding same back
over upon themselves, can be non-releasably connected with one
another. According to important aspects of the inventive seal
structure the flexible strip carries at one end at least a portion
or component of a closure and at its other end the other portion or
component of the closure or an element which can be engaged with
the closure. The one closure portion of the aforementioned closure
forms a container or receiver, at the base of which there protrudes
head member constructed as a catch element and the other closure
portion is formed by a plate which fits as a cover into this
container. This other closure portion possesses a locking element
in the form of a recess into which extends shoulder means which,
upon closing the seal, and thus pressing the head member into the
recess engages behind such head member and non-releasably fixes
such head member in its inserted position.
BRIEF DESCRIPTION OF THE DRAWING
The invention will be better understood and objects other than
those set forth above, will become apparent when consideration is
given to the following detailed description thereof. Such
description makes reference to the annexed drawing wherein:
FIG. 1 is a top plan view of a preferred constructional form of
inventive security seal prior to use thereof;
FIG. 2 is a cross-sectional view of the security seal depicted in
FIG. 1, taken substantially along the line II--II thereof;
FIG. 3 is a cross-sectional view of the security seal depicted in
FIG. 1, taken substantially along the line III--III thereof;
and
FIG. 4 is a cross-sectional view, similar to the showing of FIG. 3,
but in this case showing the security seal in its closed
position.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the invention in greater detail, there is
illustrated by way of example in the drawings a so-called "Mink
seal" that is to say a seal by means of which mink skins, and of
course, in analogous fashion also other fur skins, can be marked as
concerns quality and origin. While for the purpose of explaining
the invention the security seal thereof will be considered in
conjunction with this environment of use, it should of course be
clearly understood that other articles can be equally marked with
such seal.
The breeders of fur bearing animals are oftentimes members of an
association. The individual fur breeder identifies his skins with a
certain marking provided thereat and delivers such to a central
collecting station or deposit location. There the skins are
classified according to their different quality. Indication of such
quality occurs by changing the relevant skin marking.
In the case of mink breeders, this occurs for instance in the
following manner: The breeder marks each of his skins by means of a
sheet metal strip prior to delivering such to the collecting
location. This sheet metal strip is drawn through the eye opening
or socket of the skin and after folding such strip back upon itself
both ends are riveted to one another by tongs or pliers. The
breeder number is embossed in the sheet metal strip. The rivet
location is subsequently covered with a plastic cap which has a
flap. In the case of those skins which do not fulfill the minimum
requirements for top quality, the skin checker i.e. the person who
inspects the skins at the collecting location, removes the flap
from the plastic cap.
This system only then operates faultlessly if safeguards are
present to insure that the marking is positively retained at the
skin, and that it is not possible to remove such marking from the
skin without being detected and, for instance, again secure such to
a different skin of lesser quality.
The above described prior art procedures do not fulfill these
requirements in a number of cases, and specifically in the first
instance because oftentimes riveting of the sheet metal strip by
the breeder is not without defect. So as to be able to counteract
the danger of possible tampering, oftentimes a majority of the
received skins must be additionally provided with a seal at the
collecting station.
The inventive security seal effectively prevents all of these
drawbacks. The entire illustrated seal of this development is
constructed as a single-piece or unitary plastic injection molded
member or part, rendering possible really inexpensive manufacture
for such mass produced and throwaway articles. By referring now
more specifically to the drawings it will be understood that this
injection molded part possesses a flexible strip 1 which is
intended to be piercingly inserted through the eye socket or
opening of a skin, or when used in a different environment, in
analogous manner through an opening or number of openings of the
article or object which is to be thusly sealed. After bending back
both ends 1a and 1b of this strip 1 upon one another, it is
possible to secure the seal to the skin or the object to be sealed
by fixing these ends in a manner to be described hereinafter. So as
to insure that both ends of the strip 1 will simultaneously arrive
at the correct relative position, for performing the sealing
operation, during bending back or folding over of the strip 1 as
above described, this strip 1 is provided at approximately its
central region with a preformed resilient bending location 2 which
forms a thin bend area or weakened location. The strip 1 is
equipped with an opening 3 at the one end 1a. At its other end 1b
this strip 1 carries a closure means, generally designated by
reference character 4, and at which for the purpose of closing the
seal, the flexed-back strip portion 1 with the opening 3 can be
engaged. Thus, the end 1a of strip 1 provided with the opening 3
can be considered as constituting an element or means engageable
with the closure means 4. The closure means 4 consists of a
component or portion 5 and a component or portion 6, the component
6 being connected with the component 5 by means of a flexible
connection band 7 which extends transverse to the lengthwise axis
of strip 1.
At the region of the closure component or portion 5, defining a
container or receiver, two walls 8 and 9 delimit a compartment or
space 5a which, when the seal is closed, is closed at all sides by
the strip 1 which can enter into and out of such compartment at the
third side, and at the fourth side this compartment is closed by
the flexed-back or bent-over connection band 7.
This compartment or space 5a is closed at its bottom by the end 1b
of the strip 1 which is opposite the opening 3, this end 1b of the
strip 1 forming the bottom surface 10 of such space, as seen by
referring to FIG. 2. Bottom or floor surface 10 is provided with a
head member 11 which extends in protruding fashion out of the
central region of the surface 10. As best seen by referring to
FIGS. 3 and 4, head member 11 is constructed to possess a
substantially wedge-shaped configuration having the undercut
surfaces 12. Head member 11 is seated upon a neck portion 13, the
connection of which with the bottom surface 10 is constructed as an
intended or reference fracture location 14, as best seen by
referring to FIG. 2.
On the other hand, the component or portion 6 of the closure means
4, the outer dimensions of which are calculated such that it just
fits in the space bounded by the walls 8 and 9, possesses a recess
portion or recess 15 consisting of a conically tapering portion 16
and a compartment 17. The mutual spacing of both shoulders 18 from
one another, which shoulders or shoulder means form the end of the
conical tapered portion 16, is somewhat smaller than the largest
dimension of the head member 11 in this direction, so that upon
introducing the head member 11 into the recess 15 such, upon
passing the shoulders 18, is somewhat elastically deformed at its
hook-like wings or nose members 19, and the head member 11 can no
longer be withdrawn without destruction of the closure. Any
possible efforts in this regard are immediately thwarted by the
undercut surfaces 12, the head member 11, by the reference fracture
location 14, and by virtue of the fact that the catch element
formed by the head member 11 and the locking element of the closure
4 formed by the recess 15 are closed at all sides as well as at the
top and bottom when the closure is in its closed or shut
condition.
Now during use of the described security seal, in the open
condition thereof as depicted in FIGS. 1 and 2, the flexible strip
1 is piercingly inserted with the end 1a carrying the opening 3
leading through the eye socket or opening of a skin which is to be
marked. Thereafter the piercingly inserted portion of the strip 1
is flexed back upon itself about the prevailing bend location 2 and
onto the remaining portion of the strip 1. As a result, the opening
3 of the strip 1 comes to bear over the head member 11. The head
member 11 is now pressed through this opening 3, whereafter by
bending over the closure portion 6 about the connecting band 7 the
recess 15 is brought over the head member 11. Upon pushing together
both closure portions 5 and 6 the head member 11 enters the
compartment 17 to assume the position depicted in FIG. 4. Entry of
the head member 11 into the compartment 17 is associated with a
sound which can be acoustically detected without difficulty. The
closure resembles that of a snap-fastener with the difference that
the components, once they have been brought into their closed
position, can no longer be separated without damaging them. The
acoustically detectable snapping-in action provides an acoustical
signal for the correct functioning of the security seal. This very
simple acoustical control is accompanied by a still further optical
control in that if the seal is not properly closed the strip 1
and/or band 7 resiliently moves back into its open position.
At an optional location of the illustrated seal, for instance at
the strip 1, it is possible to impress the designation or marking
for the relevant breeder. For purposes of quality designation there
can be provided in the usual manner, for instance by molding, a
flap 20 at the closure portion, which flap can then be broken-away,
cut-off or otherwise separated in a convenient and simple fashion.
Flap 20 serves to carry information, for instance in the form of a
printed label, cardboard disk or otherwise, conveniently indicated
by reference character 20a.
A more simple constructional form of the described closure could be
realized in that at the end 1a of the flexible strip 1, instead of
the opening 3, there is provided one of the closure portions, for
instance the closure portion 6, and at the other end, as in the
illustrated embodiment, the closure portion 5. This has been
schematically indicated in FIG. 1 by the phantom lines 6'
representing the closure portion 6. With this variant construction
the one closure portion must of course be pushed through the
opening of the article to be marked, requiring a considerably
larger opening than for merely piercingly inserting the free end 1a
of the relatively thin strip 1 with its opening 3, as was the case
for the illustrated embodiment.
Both embodiments, however, fulfill the originally indicated
requirements with regard to a marking or indicator seal which is
inexpensive to fabricate, wherein it is impossible to lose any of
the individual parts, which can be easily and positively applied
and closed without the need for a tool, wherein there is provided
sufficient space for applying markings regarding origin or other
pertinent information, data or the like, and at the same time
contains a simple quality indicator, and finally wherein the seal
only can be opened if it is damaged.
By virtue of the prepared reference or intended fracture location
14 at the base of the catch element, wherein upon rupture thereof
the head member 11 drops in inaccessible fashion into the recess 15
there is practically rendered impossible false- or putative sealing
operations.
According to a further embodiment of the invention, and as briefly
previously mentioned, the flap member 20 could be constructed as a
support or carrier for further information or data concerning the
articles which are sealed with the inventive seal. It can be
constructed for instance as a label support for supporting a label
which has been adhesively bonded or attached thereto or it can also
be constructed as a flat plate surrounded by a raised edge, in the
recess of which there can be adhesively connected or injected a
printable cardboard- or paper disk. With the last-mentioned
embodiment it is not absolutely necessary to construct the thus
designed flaps 20 so as to be detachable.
The inventive security seal is exceptionally suitable for sealing
articles or objects which cannot be throughbored or provided with a
hole or wherein the existing hole for passing therethrough a strip
of the seal structure is not at least as large as the smaller
closure portion of the seal. Since namely the free end of the
flexible strip 1 in the one embodiment disclosed above does not
carry any closure portion, this free end can be guided through very
narrow slot-shaped openings, for instance the eye openings or eye
socket of skins or also through small button holes and the
like.
While there is shown and described present preferred embodiments of
the invention, it is to be distinctly understood that the invention
is not limited thereto but may be otherwise variously embodied and
practiced within the scope of the following claims.
