Description

  The present invention is, for example, a prismatic shape having a cylindrical or polygonal bottom, and deforms the side wall by double winding between the upper wall and the side wall of the container or in a region near the upper edge of the container. The present invention relates to a suspension device that can be used for a plurality of containers such as metal cans having radially projecting outer peripheral ribs.

  Suspension devices applied to containers as described above are well known from the prior art. The device includes a ring that is attached to the periphery of the container body and is mounted and locked so as to be axially raised with respect to the outer peripheral rib of the container, and an end is attached to a diametrically opposite region of the ring, substantially And at least one substantially U-shaped handle that is displaceable between a non-actuated position that assumes a coplanar position and an actuated position that rises and is substantially perpendicular to the mounting surface of the ring.

  In the non-actuated position, the handle is positioned laterally outward of the lateral extension of the container body corresponding to approximately one-half of the surrounding. In the actuated position, the handle is positioned diametrically on the container and is sufficient to suspend the container with the top lid or without the top lid so that the user's hand can be placed under the handle. Positioned to have a vertical gap.

  In some known constructions, the handle has opposite ends that are integral with the ring, and its joining area allows the angular movement of the handle between the non-actuated position and the actuated position by elastic deformation. Provided. This type of structure is disclosed in Brazilian patent application No. PI9700128-7 and Brazilian utility model MU8000935-2. The structure described in patent application No. PI9700128-7 has handles in two opposite positions.

  A monolithic suspension is typically molded from an elastically deformable plastic material, which requires a large mold that can be manufactured as an integral part of a ring and handle that are joined together in diametrically opposite bending regions. There is a problem that it is complicated and expensive. The bending region or elastic deformation region is often subjected to a shearing force to break the joint between the ring and the handle. In this known monolithic structure, there is a load limit in the joint area that is deformed when the suspension rod is moved, and the ring and handle cannot be made of different materials.

  There is also a well-known suspension device in which the ring and the handle are separate parts, and both ends of the handle are connected to the ring in the opposite region of the container body so that the handle can move between the non-actuated position and the actuated position. It is. Examples of this structure are shown in U.S. Pat. No. 3,093,257 and Brazilian utility model No. MU74902442-6.

  In a structure using these separate parts, one part of the ring and handle has a set of connecting radial pins that are fitted and supported in respective housings provided in the other part. .

  A structure with a separate part handle eliminates the problems in the one-piece structure and eliminates the strength limit, but in this structure as well, the handle is almost flush with the ring surface and around the ring. The problem is that the handle cannot be securely held in the non-actuated position of the handle that circumscribes the extension, and the ring cannot be attached to the peripheral area of the container body that is axially spaced from the upper edge area of the container body. There is a problem.

  If there is no holding means for holding the handle in the non-actuated position, the handle will unintentionally move upward toward the actuated position when the container moves along the filling line, and the filling line is stopped. Another problem arises that could end up.

  These known solutions also do not provide holding means that act on the handle to keep it fixed in the raised operating position. In these solutions, when the handle is released in the actuated position raised by the user, the handle tends to drop to a position lateral to the container body by gravity. This position is opposite to the non-actuated position, and the holding means may act on the handle to hold the handle in this state.

  Another possible aspect of the structure of the suspension device of the present invention is the supply of the device to a magazine of a machine that mounts the device around the container body. In this situation, the suspensions must be stably stacked in the magazine so that each suspension can be released individually. Known solutions do not mention this problem.

  Because the ring cannot be mounted away from the top edge of the container, this monolithic structure cannot be mounted on a container that cannot form a peripheral rib to hold the ring due to insufficient finishing of the top edge . In these cases, the outer peripheral rib is formed in a region axially spaced from the upper edge of the container body, so that the upper region of the container operates to prevent (or hinder) the angular displacement path of the handle. When it is not in the position or when it is in the operating position, it remains in a state of being hardly separated from the upper wall of the container, which makes it difficult to operate, and also allows the user's hand to grasp the handle sufficiently Disappear.

  By providing the locking means, the handle is securely held in the non-actuated position without the risk of being unintentionally displaced towards the actuated position raised above the container.

  In the method for carrying out the present invention, the locking means is structured to act on the handle not only in the non-operating position of the handle but also in the raised operating position, and the handle can be fixed even in the raised position.

  According to another possible method of practicing the invention, the ring has an upper edge and a lower edge, the upper edge and the lower edge can not only be mounted so that the ring can be accurately raised on the outer peripheral rib of the container body.

  Each radial pin 21 includes an enlarged head 22 that is contoured larger than the width of the through opening 33 in order to operate properly. Each of the through openings 33 has an inner end, and the inner end is the end opposite to the outer end edge 33b, and usually the elastic deformation of the enlarged head 22 of the radial pin 21 and the through opening 33. Is opened toward the enlarged hole 34 having a contour of a dimension that allows the enlarged head 22 to pass therethrough.

  According to the third embodiment of the present invention as shown in FIGS. 8 to 10, the through-openings 33 of each end 31 of the handle 30 have parallel and linear opposing side edges 33 a, Each radial pin 21 has a polygonal cross section including two first surfaces 21a, the first surfaces 21a being surfaces facing each other along the axial direction of the ring 20, and the handle 30 is inoperative. When in position, each fits securely into one of the opposing edges 33a of each through opening 33. With this structure, the first surface 21a of each radial pin 21 is fitted to the opposite side edge of the through opening 33 to form a locking means 40 that secures the handle 30 in the inoperative position. The polygonal cross section of the radial pin 21 allows the handle 30 to be rotatably locked when the handle is in the inoperative position, as shown in FIG.

  Furthermore, according to the third embodiment of the present invention, the polygonal cross section of each radial pin 21 can also comprise two second surfaces 21b. The second surfaces 21b are surfaces that face each other along a direction orthogonal to the axial direction of the ring 20, and as shown in FIG. 10, when the handle 30 is in the operating position, the second surfaces 21b face each other. Each of the side edges 33a is securely fitted to one of the side edges 33a. In this construction, the second surface 21b of each radial pin 21 forms a locking means 40 that can fix the handle 30 even in the operating position of the handle.

  As described above with respect to the two first embodiments, the through opening 33 at each end 31 of the handle 30 further has an outer edge 33b so that the handle 30 is in the operative position as shown in FIG. Thus, when the container is suspended, one of the first surfaces 21a of the polygonal cross section of each radial pin 21 is fitted to the outer edge 33b.

  Furthermore, in the third embodiment of the present invention, each radial pin 21 includes an enlarged head 22 having a contour larger than the width of the through opening 33, and each of the through openings 33 has an inner end. The inner end portion opens toward the enlarged hole 34 at the end opposite to the outer end edge 33b, and the enlarged hole 34 can normally pass the enlarged head 22 of the radial pin 21. At least one of the components having a dimensional profile and included in the mounting structure is elastically deformed.

  Although not shown in the accompanying drawings, when the outer peripheral rib 14 is formed near the upper edge 12 of the container (usually, as shown in FIG. 11, the outer peripheral rib 14 is formed on the peripheral side wall 11 of the main body 10 and the upper wall 10a. The length of the through opening 33 at each end 31 of the handle 30 corresponds to the cross-section of the radial pin 21 in order to support the radial pin 21 firmly. It may be shortened to form a hole with a cross section. This is because the handle 30 can be angularly displaced between the non-actuated position and the actuated position without contacting the contour of the container and mainly without contacting the contour of the upper edge 12 of the container.

  However, as shown in FIGS. 1 to 10, when the outer peripheral ribs 14 are formed in the region of the peripheral side wall 11 of the main body 10 that is axially spaced from the upper edge 12 of the main body 10, each end 31 of the handle 30. The through-opening 33 of the handle is used to increase the angular displacement radius of the handle to avoid contact with the upper edge 12 of the body 10 when the handle 30 is moved between the non-actuated position and the actuated position. It takes the form of an elliptical slot arranged longitudinally in the handle 30 so that 30 can be displaced radially relative to the axis of the two radial pins 21.

  In order to prevent inadvertent displacement of the handle 30 relative to the radial pin 21 from positioning any of the pins in alignment with each of the enlarged holes 34 in the end 31 of the handle 30, as shown in FIG. 8A. Each opposing side edge 33a of each through opening 33 may be provided with a protrusion 36 to restrict the radial pin 21 from being freely displaced toward the enlarged hole 34 of each through opening 33. it can.

  Although only three structural embodiments of the suspension of the present invention are shown herein, the structure of the suspension is not deviated from the concept of the structure described in the claims appended hereto. The parts can have different forms.
