Description

Cover and assembly made with a support and a top.

This invention relates to a cover intended for a container, whose container comprises a bottom and a wall envelope, and an upper edge intended for coupling with the lid, with the surrounding wall connected adjacent to the edge top one tab of the container that extends substantially perpendicular to the surrounding wall, the cover comprising a wall cover that is provided on a circumferential edge with a wall closing that extends in the downward direction and that, to through a side near the wall of the lid, it is attached to the upper edge, the closing wall being provided with an edge descending that, in a condition where the lid is placed on the container is placed very close against the tab of the container extending perpendicularly to the surrounding wall, or is thus protected by the surrounding wall or a portion of the wall which extends substantially parallel to the surrounding wall, of so that the coupling of this edge is not possible falling.

A lid of this type, together with a container designed as a bucket, is described, for example, in the applicant's European patent application
EP-A-0 855 347. For the purpose of opening the lid of this known assembly, the assembly container is provided with a sealing projection that can be broken, so that the user can grasp the falling edge of the wall of closing the lid in order to open the lid. Although in the known hub the seal rupture hardly causes the weakening of the container, however, this danger is still present. The invention contemplates a lid of the type described in the preamble, intended for a container, which does not require the breaking of any of the pieces of the container to remove the lid of the container, so that the container retains its original stiffness while it can still be provided a seal.

For this purpose, according to the invention, the cover of the type described in the preamble is characterized in that in a coupling position edge coupling not possible descending, while in the coupling position, it is connected a coupling projection with the closing wall, whose coupling projection can be easily coupled and which after coupling extends from the closing wall, of so that in a natural way, the container lid separation.

Since the falling edge of the wall of closure cannot be attached at any point, the user, for the purpose if you open the lid, you will have to pull the coupling projection, so that the closure wall adjacent to the coupling boss separates from the top edge of the container, after this the lid It can be released from the container. The container tab, and the portion of wall possibly connected to the tab of the container, can extend across the entire circumference of the container without an interruption or any change in the profile for the purpose of forming a sealing projection. The container will therefore have substantially the same stiffness at along its circumference.

To additionally provide the set with a sealing gasket, is particularly favorable, according to a further elaboration of the invention, that when the wall of closure, at least on any side of the projection of coupling is provided with a provision of weakening, while the design and placement of the projection of coupling, after coupling of the coupling boss for the opening of the lid, a direction of traction that is such that at least a portion of the closing wall of the closing wall remaining limited by the weakening provisions is partial or totally loosened by breaking the provisions of weakening

In these operations, the provisions of mentioned weakening will break, whose breakage is visible, of so it is clear that the lid has been removed from the container before. The weakening provisions therefore have the sealing function that is of great importance in view of any suitable opening of the assembly according to the invention. In addition, by breaking the provisions of weakening, the closing wall is broken, so that the force that must be applied to remove the top edge cap is considerably reduced.

It should be noted that it is known, in itself, of document DE-U-8906937.4 provide weakening provisions in the closing wall of a lid to simplify the opening of the lid. However, in the case of the cover described in this publication, the cover can be container removal without breaking the provision of weakening, since the lower edge can engage in the coupling area When the pushing force is exerted towards up in the direction of the closing wall, the provisions of weakening will not break and the lid can open without being leave marks. In addition, the known cover of the Utility model mentioned is not provided with a coupling boss, allowing only one coupling projection that after coupling extends from the closing wall, so that of in a natural way, the separation of the container lid

According to an alternative elaboration, in place of or in addition to the planned weakening provisions on any side of the coupling boss, the cover can be provided with a sealing bridge in the position of coupling whose sealing bridge is connected to the wall of closing and, optionally, with the coupling boss, so that after coupling of the coupling boss, it breaks at least one of the connections of the sealing bridge with the wall of Close or with the coupling boss. When a user observes that such a connection has been broken, you can assume that the cover it has been taken once from the container, unless a I try for this effect.

The invention further relates to a assembly of a lid according to the invention and a container. According to a further elaboration of the invention, the container can be designed as a bucket, which is manufactured, for example, of plastic, or as a can that can be manufactured of metal and which is provided with a double upper edge in the part higher. The closing wall of the lid then falls between the wall envelope and a wall portion connected to the tab of the container, extending parallel to the surrounding wall.

In the figures, the parts that have the same Function will be designed by the same reference numbers. The Containers shown in Figure 4, 5, 14 are plastic buckets. The container shown in part of Figure 25 is a can. All the caps D shown in the exemplary embodiments are made of plastic. However, there are also options for other materials for manufacturing the container and / or the lid. Figure 4 shows in cross section a complete set of a container E and a lid D. Container E comprises a bottom 1 and a surrounding wall 2.

A tab of container 4 is provided adjacent to the upper edge 3 of the envelope wall 2, which is extends substantially perpendicular to the enclosure wall 2. A part of the wall 5 is connected with an edge 4a of the flange of the container 4 separated from the enclosure wall 2, which extends substantially parallel to the surrounding wall 2. Extending between this part of the wall 5 and the surrounding wall 2, in this For example, there are 6 ribs to improve the resistance of the container E. However, such ribs are not required. The lid D comprises a lid wall 7. In its circumference, the lid D is provided with a closing wall 8 that extends in a descending direction and through its side near the wall of the lid 7 is coupled to the upper edge 3 of the container E, whose upper edge 3 in this case is formed by the upper edge 3 of the surrounding wall 2. The closing wall 8 is provided with a falling edge 8a which, in a condition of the lid D when it is placed on container E, it is placed very closely against the tab of the hub 4 extending perpendicular to the wall envelope 2, or is thus protected by the part of the wall 5 that is extends substantially parallel to the enclosure wall 2, so that the coupling of this falling edge 8a is not possible. For to be able to remove the lid D of the container E, the falling edge 8a of the closing wall 8 is connected, in a position of coupling, with a coupling projection 9 extending from the falling edge 8a so that it can be attachable. Preferably, such a coupling is produced by the fingers, but "dockable" should be understood to include dockable with a tool, such as pliers or a screwdriver. In Figure 5, this coupling projection 9 is indicated by points. Figure 3 shows the coupling projection 9 in the original position and in a coupled position designated with 9a. In the Figure 4, the cover D is represented while it is placed on the container E, with coupling boss 9 in position coupled. Figures 6 and 7 show the coupling boss 9 represented in Figures 1-5, once again in a top floor view and a side elevation view in the position not yet coupled. Figures 8 and 9 show the projection of coupling 9 in a top plan view and a view in lateral elevation, respectively, in the coupled position. In particular, in figure 9, it is clearly visible that in the position coupled an opening 18 is formed in the closing wall 8, under the which fingers can slide to loosen the cover D of the container E.

Figures 10-13 show a number of alternative designs of the coupling boss 9 in the same position and elevation view as shown in the figure 8.

Figure 14 shows the cross section to along line XIV-XIV in Figure 13. Sample clearly that in this exemplary embodiment, the projection of coupling 9 is held in the coupling position through of a breakable connection bar 19.

The closing wall 8 is provided with a weakening provision 10-12, at least on any side of the coupling boss 9. This weakening provision 10-12 is clearly visible in the various exemplary embodiments of the figures. 15-18, and designated there by reference numbers 10, 11 and 12, respectively. The weakening provisions
10-12 are provided so that when the coupling projection 9 is coupled and, for the opening of the cover D, is pushed laterally and upwards, at least a portion of the closing wall 8b of the remaining closing wall is loosened 8 which is delimited by the weakening provisions
10-12 and remains connected with the cover D only through a side separated from the falling edge 8a, so that the loosened wall portion 8b can be coupled for additional opening of the cover D. In this condition, it is created the opening 18, mentioned above, which is indicated in Figures 4 and 9 and under which the user can slide his fingers for the additional opening of the cover D.

In all exemplary embodiments represented in figures 15-18, a tab 14, which extends substantially parallel to the wall of the cover 7 with the falling edge 8a of the closing wall 8. The 10-12 weakening provisions extend then also in this tab 14 on the opposite sides of the coupling boss 9. In the exemplary embodiment of Figure 15, the weakening provisions in tab 14 they are designed as breaks, while the provisions of weakening in the closing wall 8 are designed as a thin wall film In figure 16, the thin wall film It is represented in perspective and partially in section cross. As the coupling boss 9 is pushed laterally and upwards, this film is broken, which makes visible that at least one attempt has been made to remove the lid D of the container E. In Figure 17 it is also clearly visible that tab 14 is interrupted in the provision of weakening 11 and that the closing wall 8 is of a thin wall design in the provision of weakening 11.

In the exemplary embodiment represented in Figure 18, the weakening provisions 12 in the wall of closure 8 are designed as recesses, and in tab 14 that connects with the closing wall 8 they are designed as films 12a. Will be obviously other types of provisions of weakening, such as perforations, connection elements breakable and similar.

In order to make folding easier of the closing wall portion 8b, can be provided additionally a weakened line 15 in the closing wall 8, whose weakened line 15 is represented in cross section in the Figure 5, and that extends between the weakening provisions 10-12, substantially parallel to the edge descending 8a of the closing wall 8. In the embodiments copies present, this weakened line 15 is designed equally mode as a thin wall film on the closing wall 8. For this weakened line 15, in addition, other forms of embodiment such as, for example, perforations or the like. The weakening line 15 can become so weak that after push the protrusion of the cover 9, the closing wall portion 8b which is bounded by weakened line 15 and the two provisions 10-12 weakening provided on the wall of closing on any side of the projection of cover 9, are completely loosened from the closing wall 8 to form a recess 18 in the closing wall 8. Recess 18 in the wall of closure 8 has a configuration such that coupling is possible of the edge that delimits this recess 18 for the end of the opening of the cover D. As described above, it is also possible that the part of the closing wall 8b remains connected through the weakened line 15 with the rest of the closing wall 8 and, for so, be only partially loosened from the closing wall 8.

Although not a requirement, in all forms of exemplary embodiment shown in the figures 1-21, the cover D is additionally provided with a connection wall 17 extending between a circumferential edge 16 of the cover wall 7 and the closing wall 8 in one direction ascending with respect to the wall of the lid 7, while the upper edge 17a of the connection wall 17 is connected to a upper edge 8c of the closing wall 8, so that the edge upper 3 of the enclosure wall 2, in a condition of the cover D when placed on container E, it is limited between the wall connection 17 and the closing wall 8. In this way, you can achieve an air tight seal between the cover D and the container E.

Figures 19 and 20 show two forms of realization of a cover edge adjacent to the position of coupling with an alternative solution for a seal. In this workaround, adjacent to the coupling position, is provided a sealing bridge 20. The sealing bridge 20 is connected to the closing wall 8 and optionally with the projection of coupling 9, so that after coupling the coupling projection 9, at least one of the connections is broken of the sealing bridge 20 with the closing wall 8 or with the projection coupling 9. In the exemplary embodiment shown in Figure 19, the sealing bridge 20 extends over the side of the coupling projection 9 separated from the closing wall 8. In the exemplary embodiment of figure 20, the bridge of sealing 20 extends between the closing wall 8 and the projection of coupling 9. In the exemplary embodiments present, the sealing bridge itself is provided with provisions of weakening 23 that will break as the projection of coupling 9 is pushed up, so that the bridge of Sealing 20 is loosened from the closing wall 8 of the lid. In the exemplary embodiment of figure 19, the sealing bridge 20 is connected through connections 22 with the projection of coupling 9. When these connections 22 are of robust design, the sealing bridge 20 will be pushed up along with the coupling projection 9, and breakable connections will be broken 23. However, it is also possible that breakable connections 23 are not present and that connections 22 are designed as breakable connections 22. The sealing bridge 20 then remains connected to the closing wall 8 of the lid, but after push up the coupling boss 9, the connections breakables 22 are loosened, so that a user can say that You have tried once to open the lid.

It should be noted in passing that both figures clearly show that the closing wall 8 is provided on any side of the coupling boss 9, with interruptions 21 delimiting a portion of closing wall 8b, so that after coupling of the coupling boss 9, this closing wall portion 8b is pushed up along with the coupling boss 9.

Figure 21 clearly shows that the bridge of sealed 20 may be optionally connected through breakable connections 24, 25, with the closing wall portion 8b or with the flange 14 connected to the closing wall portion 8b. For this case, these connections 24, 25 may be designed also as non-breakable connections, so pushing towards above the coupling boss 9, the sealing bridge 20 is loosening of the closing wall 8 breaking the provisions of weakening 23 in the sealing bridge 20.

It will be apparent that container E may be equipped with a handle that may or may not be made of plastic for form a cube When container E is not provided with a handle, It is commonly designed in practice by the term "pan".

Figures 22-27 show a exemplary embodiment of a cover intended to be placed On a can. As clearly depicted in Figure 25, the can has an upper edge 33. The upper edge 33 is part of a portion of the wall 35 that extends substantially parallel to the surrounding wall 32 and that is connected to the wall envelope 32 of the can through a flange of can 34. The lid D is coupled to the upper edge 33 of the can through the closing wall 38. The falling edge 38a of the closing wall 38 of the lid is not attachable since it is arranged between the Surrounding wall 32 and the part of the wall 35. To allow, without However, that the lid be removed from the can, a projection of coupling 39 is connected to the closing wall 38. The coupling projection 39 is connected to a part of the wall closure 38b delimited by weakening provisions 40 that break when the lid D is removed from the can. The outgoing of coupling 39 is adapted in a storage condition in a chamber 41. The chamber 41 is formed by a wall portion of lid lowered 37a on the wall of the lid 37. The wall portion of cover down 37a is connected to the wall of the cover 37 through of the walls of the chamber 42 which extend substantially from perpendicular to the wall of the lid 37. To maintain the coupling projection 39 in the storage condition, in the present exemplary embodiment, two chamber walls 42 they are provided with an elastic lace edge 43 behind which the coupling boss 39 is elastically fitted in the storage condition To remove the lid D from the can, the coupling projection 39 is coupled and carried from the storage condition within an oscillating position towards above, which requires the ledge to move out of the chamber 41 removing from below the edges of elastic lace 43. When subsequently, the coupling projection 39 carried in the oscillating upward position, is pushed, the weakening provisions 40, so that the wall of the closure 38, the tension of the closure is removed and the cover D can be pushed further from the can while a small force Since the coupling boss 39 in the storage condition is arranged in chamber 41, the caps are stackable with little loss of space, which is clearly depicted in figures 26 and 27. The plan view Figure 22 shows the coupling projection 39 in an unfolded position, that is, that moves out of the chamber 41. In Figures 23-27, the projection of coupling 39 is arranged in the chamber 41, under the edges of elastic lace 43.

It will be apparent that the invention is not limited to the exemplary embodiment described, but are possible several modifications within the scheme of the invention. So, the container and the lid may consist of a part since they are connected to each other with a joint or a part of Connection.
