Description
FIELD OF THE INVENTION
[0001] The present invention refers to a suspension device to be
applied to several containers such as, for example, metal sheet
cans presenting a prismatic shape with cylindrical or polygonal
bases and being provided with a radially projecting external
peripheral rib and which can be defined by the double-seam provided
between the upper and lateral walls of the container, or by
deforming said lateral wall in a region which is close to an upper
edge of the container.
BACKGROUND OF THE INVENTION
[0002] There are known from the prior art the suspension devices
for the type of container mentioned above, said devices comprising
a ring, to be applied around the container body and axially and
ascendingly seated and locked against the external peripheral rib
of the container, and at least one generally U-shaped handle,
having its ends affixed in diametrically opposite regions of the
ring, so as to be displaced between an inoperative position, in
which it occupies a position substantially coplanar to the ring,
and an operative position, which is elevated and generally
orthogonal to the seating plane of the ring.
[0003] In the inoperative position, the handle is positioned
laterally and externally to a respective lateral extension of the
container body, generally corresponding to half the perimeter. In
the operative position, the handle is diametrically positioned over
the container, with a vertical gap sufficient to allow the user's
hand to be positioned under the handle and, thus, to allow the
suspension of the container, carrying or not carrying an upper
lid.
[0004] In some known constructions, the handle has its opposite
ends incorporated, in a single piece, to the ring, the junction
region being constructed to allow, by means of its elastic
deformation, the angular movement of the handle between its
inoperative and operative positions. Constructions of this type are
disclosed in Brazilian documents PI 9700128-7 and MU 8000935-2, the
first of them presenting two diametrically opposite handles.
[0005] Since the suspension devices in a single piece are generally
molded in an elastically deformable plastic material, they present
the inconvenience of requiring a larger mold, more complex and more
costly, which is capable of producing, in a single piece, the ring
and the handle connected to each other by diametrically opposite
bending regions. The bending or elastic deformation regions are
frequently exposed to shear forces sufficient to provoke rupture of
the junctions between the ring and the handle. This known
construction in a single piece presents load limitations in the
junction regions to be submitted to deformation upon the movement
of the suspension rod, and prevents the ring and the handle from
being produced in different materials.
[0006] There are also known the suspension devices in which the
ring and the handle are constructed in separate pieces, with the
handle ends being articulated to the ring, in opposite regions of
the container body, so that the handle can be moved between the
inoperative and operative positions. Examples of these previous
constructions may be observed in patent documents U.S. Pat. No.
3,093,257 and BR MU 74902442-6.
[0007] In these constructions using separate pieces, one of the
parts of ring and handle carries a pair of articulating radial
pins, to be fitted and supported in respective housings provided in
the other of said parts.
[0008] Although eliminating the inconveniences regarding the single
piece constructions and their strength limitations, the
constructions with the handle in a separate piece also present the
inconveniences of not guaranteeing a reliable retention of the
handle, in its inoperative position, substantially coplanar to the
plane of the ring and externally adjacent to an extension of the
periphery of the latter, and not allowing mounting the ring to a
container body circumferential region axially spaced from the upper
edge region of said container body.
[0009] The lack of a means for retaining the handle in the
inoperative position allows said handle to be involuntarily and
undesirably upwardly moved towards its operative position, during
the movement of the container in the filling line, causing
different problems which can paralyze said filling line.
[0010] These known solutions also do not present a retention means
which actuates on the handle, so as to maintain it stabilized in
its elevated operative position. In these solutions, when the
handle is released, by the user, in the elevated operative
position, it tends to move descendingly, by gravity force, to a
position lateral to the container body, which position can be
diametrically opposite to that inoperative position in which the
retention means can actuate on the handle, retaining it in this
condition.
[0011] Other aspect to be considered in the construction of the
present suspension devices refers to the feeding of said devices
into a magazine of a machine for mounting them around the container
bodies. In this condition, the devices must be stably stacked in
the magazine, so as to allow each device to be individually
released. The known solutions do not refer to this problem.
[0012] The impossibility of mounting the ring spaced from the upper
edge of the container prevents this construction in a single piece
from being mounted to containers in which the finishing of their
upper edge is not sufficient to provide the external peripheral rib
which retains the ring. In these cases, the external peripheral rib
is provided in the container body, in a region thereof axially
spaced from the upper edge, making the upper region of the
container impair (or interfere in) the angular displacement path of
the handle, preventing it from reaching its operative position or,
when in said operative position, remaining very little spaced from
the upper wall of the container, making the handling uncomfortable
or even impairing the adequate gripping of the handle by the user's
hand.
SUMMARY OF THE INVENTION
[0013] As a function of the inconveniences of the known solutions
provided in a single piece or in separate pieces, the invention
has, as one of its objects the provision of a suspension device in
two pieces, with a simple and cost-effective construction which can
be easily mounted to the container, and which can have its handle
reliably maintained in an inoperative position and also taken to an
operative position, adequately spaced from the upper wall of the
container, independently of the axial distance between the external
peripheral rib and the upper edge of the container.
[0014] The inventions has also the object of providing a suspension
device as mentioned above and which can have its handle reliably
stabilized in the operative position elevated over the
container.
[0015] As already mentioned, the present device is applied to a
container having a body provided with a surrounding lateral wall,
an upper edge and an external peripheral rib, the device being
formed: by a ring incorporating two opposite external radial pins
and which is ascendingly seated and locked against the external
peripheral rib, around the body; and by a U-shaped handle, having a
median portion and end portions, each articulated in one of the
radial pins, said handle being angularly displaced, around the
radial pins, between an inoperative position, lateral and external
to the body, and an elevated operative position, disposed over the
body.
[0016] According to the invention, the ring further incorporates,
externally, a lock means which actuates against an adjacent portion
of the handle and which stabilizes the latter in an inoperative
position, each end portion of the handle being provided with a
through opening, through which is supported a respective radial
pin, said through opening presenting a width, in the direction
transversal to the handle extension, sufficient to tightly support,
in said direction, the radial pin, and a length, in the
longitudinal direction of the handle, sufficient to support the
radial pin, both with the handle in the inoperative position and
stabilized by the lock means and with the handle in an angular
displacement from the inoperative position to the operative
position.
[0017] The construction proposed herein allows obtaining a
suspension device which can have its two component parts
constructed in different materials and which can have its ring
retained to the container body in a position spaced from the upper
edge of the latter, without impairing the correct angular movement
of the handle between its inoperative and operative positions.
[0018] The provision of the lock means allows the handle to be
reliably retained in its inoperative position, without the risk of
being involuntarily and undesirable displaced to its operative
position elevated above the container.
[0019] In a way of carrying out the invention, the lock means Ls
constructed to actuate on the handle not only in the inoperative
position of the latter, but also in the elevated operative position
of the handle, allowing the latter to be stabilized also in its
elevated position.
[0020] Further according to another possible way of carrying out
the invention, the ring has an upper edge and a lower edge which
are configured to allow not only the correct ascending seating of
the ring against the external peripheral rib of the container body,
but also the stable stacking of the rings in a magazine of a
machine for mounting a suspension device around a container
body.

DESCRIPTION OF THE INVENTION
[0035] As already mentioned and illustrated in the enclosed
drawings, the present suspension device is applied to containers
which comprise a body 10 generally formed in metal sheet or in any
other adequate laminar material, presenting a prismatic shape with
cylindrical or polygonal bases.
[0036] The body 10 includes a surrounding lateral wall 11,
presenting only one cylindrical face or a plurality of faces with
polygonal contour, being superiorly limited by an upper edge 12
and, inferiorly, by a lower edge (not illustrated).
[0037] The surrounding lateral wall 11 incorporates an external
peripheral rib 14, which can be defined by deforming a
circumferential region of the surrounding lateral wall 11 of the
body 10 of the container, axially spaced from the upper edge 12 of
said body 10. This constructive variant of the container is that
represented in FIGS. 1 to 10 of the enclosed drawings.
[0038] FIG. 11 illustrates a construction of a container provided
with an upper wall 10a which, in the present example, presents an
annular shape to define a seat for seating a lid (not illustrated).
The upper wall 10a is peripherally double seamed to the upper edge
12 of the surrounding lateral wall 11, said double seaming of the
upper wall 10a to the surrounding lateral wall 11 defining the
external peripheral rib 14 of the body 10.
[0039] The suspension device A considered in the present invention
is of the type formed by a ring 20, preferably continuous and
formed in a plastic material or any other material which allows
obtaining an element, in the form of a belt, to be relatively
tightly mounted around the body 10 of the container, in order to be
ascendingly seated and locked against the peripheral rib 14 of the
body 10 of the container, as illustrated in FIGS. 2 to 5 and 9 to
11.
[0040] As illustrated in FIGS. 2, 3, 7 and 9 to 12, the ring 20
comprises: an upper edge 20a, which is cutout so as to define an
inner annular step 27, turned upwards and recessed in relation to
said upper edge 20a and to be ascendingly seated and locked against
the peripheral rib 14 of the body 10; and a lower edge 20b, which
is cutout so as to define an outer annular step 28, turned
downwards and recessed in relation to said lower edge 20b, which is
seated on the inner annular step 27 of other ring 20 disposed
immediately below, in a stack of rings 20. This construction
guarantees an adequate stability for stacking the rings in a
magazine, facilitating mounting the devices around the body of the
containers.
[0041] The ring 20 incorporates, externally, in opposite regions
and generally in a single piece, two radial pins 21, each
preferably provided with a respective enlarged head 22.
[0042] The suspension device A further comprises a generally
U-shaped handle 30, formed in any suitable material, such as
plastic, having end portions 31 respectively articulated in the
radial pins 21, and a median portion 32, the handle being angularly
displaced, around the axis common to the two radial pins 21,
between an inoperative position, in which it is positioned
laterally and externally to a respective lateral extension of the
body 10 of the container and of the ring 20, generally
corresponding to half the perimeter of the container and of the
ring, and an operative position, in which it is positioned over the
container. The operational positions of the handle are illustrated
in FIGS. 4, 5, 9 and 10.
[0043] According to the invention, the ring 20 also incorporates,
externally, a lock means 40, which actuates against an adjacent
portion of the handle 30, to stabilize the latter in its
inoperative position. The lock means 40 prevents the handle 30 from
being involuntarily displaced from its inoperative position to its
elevated operative position.
[0044] According to a first constructive embodiment illustrated in
FIGS. 1 to 5, preferably enlarged median portion 32 of the handle
30 is provided with a through hole 32a, the lock means 40
comprising a lock pin 25, radially and externally incorporated to
the ring 20, provided with an enlarged head 25a and to be fitted
through the through hole 32a of the median portion 32, by elastic
deformation of at least one of the parts defined by the handle 30
and by the enlarged head 25a of the lock pin 25. This construction
allows the handle 30 to be reliably locked in its inoperative
position during the handling, transport, filling and storage
operations of the container, preventing the involuntary elevation
of the handle from causing any inconvenience to the use of said
suspension device A.
[0045] According to a second constructive embodiment illustrated in
FIGS. 6 to 7, and using a handle 30 equal to that illustrated in
FIG. 1A, but deprived of the through hole 32a in the median portion
32, the lock means 40 comprises a radial projection 26, which is
superiorly and externally incorporated to the ring 20, generally in
a single piece and provided with an end lower projection 26a,
preferably in the form of a descending flange, the median portion
32 of the handle 30, in the inoperative position of the latter,
being fitted and retained under the radial projection 26, with all
the benefits mentioned above for reliably locking the handle 30 in
the inoperative position.
[0046] Each end portion 31, preferably enlarged, of the handle 30,
is provided with a through opening 33, through which is supported a
respective radial pin 21 of the ring 20. The through opening 33
presents a width, in the direction transversal to the extension of
the handle 30, sufficient to tightly support, in said direction,
the radial pin 21, and a length, in the longitudinal direction of
the handle 30, sufficient to support the radial pin 21, both with
the handle 30 in the inoperative position and stabilized by the
lock means 40, and with the handle 30 in angular displacement from
the inoperative position to the operative position.
[0047] In the first and second embodiments of the invention, in
which the lock means 40 takes the form of the lock pin 25 or of the
radial projection 26, so as to actuate in the median portion 32 of
the handle 30 when in the inoperative position, the through opening
33 of each end portion 31 of the handle 30 presents opposite
lateral edges 33a, which are parallel and rectilinear and against
which are tightly seated opposite regions of the generally circular
cross section of the respective radial pin 21.
[0048] In these embodiments, the through opening 33 further
presents an outer end edge 33b, against which is seated the
respective radial pin 21, when the handle 30 is in the operative
position and suspending the container, as illustrated in FIG.
5.
[0049] In order to operate in an adequate manner, each radial pin
21 incorporates an enlarged head 22 with the contour larger than
the width of the through openings 33, each of the latter presenting
an inner end, opposite to the outer end edge 33b and opened to an
enlarged hole 34 with a contour dimensioned to allow the passage of
the enlarged head 22 of the radial pin 21, generally with a small
elastic deformation of the enlarged head 22 or of the through
opening 33.
[0050] According to a third embodiment of the invention,
illustrated in FIGS. 8 to 10, the through opening 33 of each end
portion 31 of the handle 30 presents opposite lateral edges 33a,
which are parallel and rectilinear, each radial pin 21 presenting a
polygonal cross section, comprising: two first faces 21a, opposite
to each other, according to the axis direction of the ring 20 and
each being tightly seated on one of the opposite lateral edges 33a
of the respective through opening 33, when the handle 30 is in the
inoperative position. With this construction, the first faces 21a
of each radial pin 21 are seated against the opposite lateral edges
of the through opening 33, defining the lock means 40 which
stabilizes the handle 30 in its inoperative position. The polygonal
cross section of the radial pins 21 makes the handle 30 be
rotatively locked thereby, when in its inoperative position, as
illustrated in FIG. 9.
[0051] Further according to said third embodiment of the invention,
the polygonal cross section of each radial pin 21 can also comprise
two second faces 21b, opposite to each other, according to a
direction orthogonal to that of the axis of the ring 20 and each
being tightly seated on one of the opposite lateral edges 33a of
the respective through opening 33, when the handle 30 is in the
operative position, as illustrated in FIG. 10. In this
construction, the second faces 21b of each radial pin 21 define a
lock means 40, capable of stabilizing the handle 30 also in its
operative position.
[0052] As already described in relation to the two first
embodiments, the through opening 33, of each end portion 31 of the
handle 30, also presents an outer end edge 33b, against which is
seated one of the first faces 21a of the polygonal cross section of
the respective radial pin 21, when the handle 30 is in the
operative position and suspending the container, as illustrated in
FIG. 10.
[0053] In the constructive form illustrated in FIGS. 8 to 10, the
polygonal cross section of the radial pins 21 is square and the
outer end edge 33b of the through openings 33 is rectilinear and
orthogonal to the opposite lateral edges 33a of the latter.
[0054] Also in said third embodiment of the invention, each radial
pin 21 incorporates an enlarged head 22 with a contour larger than
the width of the through openings 33, each of the latter presenting
an inner end, opposite to the outer end edge 33b and opened to an
enlarged hole 34 with a contour dimensioned to allow the passage of
the enlarged head 22 of the radial pin 21, generally with the
elastic deformation of at least one of the parts involved in this
mounting arrangement.
[0055] Although not illustrated in the enclosed drawings, when the
external peripheral rib 14 is defined close to the upper edge 12 of
the container, which generally occurs when the external peripheral
rib 14 is defined by double seaming the upper wall 10a to the
surrounding lateral wall 11 of the body 10, as illustrated in FIG.
11, the through opening 33, in each end portion 31 of the handle
30, can have its length reduced to define a hole with its cross
section corresponding to that of the radial pin 21, for tightly
supporting the latter, since the handle 30 can be angularly
displaced between its inoperative and operative positions, without
interfering with the contour of the container, mainly with the
contour of the upper edge 12 of the latter.
[0056] However, when the external peripheral rib 14 is defined in a
region of the surrounding lateral wall 11 of the body 10 axially
spaced from the upper edge 12 of the body 10, as illustrated in
FIGS. 1 to 10, the through opening 33, in each end portion 31 of
the handle 30, takes the form of an oblong slot longitudinally
disposed in the handle 30, so as to allow the latter to be
displaced radially in relation to the axis of the two radial pins
21, in order to increase its angular displacement radius, avoiding
any interference contact with the upper edge 12 of the body 10,
when said handle is moved between the inoperative and operative
positions.
[0057] In order to prevent an inadvertent displacement of the
handle 30, in relation to the radial pins 21, from positioning any
of said pins 21 aligned with the respective enlarged holes 34 of
the end portions 31 of the handle 30, the opposite lateral edges
33a, of each through opening 33, can be provided, with respective
projections 36 for limiting the free displacement of the radial
pins 21 towards the enlarged hole 34 of the respective through
opening 33, as better illustrated in FIG. 8A.
[0058] While only three constructive embodiments for the present
suspension device have been illustrated herein, it should be
understood that the component parts of said suspension device can
have different forms, without departing from the constructive
concept defined in the claims which accompany the present
specification.
