Description

Field of the invention

The invention relates to a cover set for closing a stackable container. The lid set comprises at least two closure receiving devices.

The invention also relates to a container set with a container and a lid. The container is rectangular in shape and has a short and a long side. It further comprises a stepped base and a container opening with an edge, so that when identical containers are stacked on top of one another, the stepped base dips into the container opening of the container stacked below.

background

Stackable containers, also called bundles, are used in industry for storage and transport. They are often made of high quality plastic. The stackable containers are used in the food industry, for example in butchers, bakeries and retailers. In these industries, the stackable containers not only have to be stable and durable, but also hygienically impeccable. The stackable containers are also used in other branches of industry in which hygiene is not of particular relevance.

The stackable containers differ, for example, in their sizes, in the design of the side walls, the base and the handle openings.

The stackable containers can be stacked on top of one another and closed with lids. In the industry, the flexible applications of the stackable containers are of great importance.

Presentation of the invention

It is the object of the present invention to provide a cover set for closing a stackable container, the closure options being optimally adaptable to the wishes of the user.

This object is achieved by the cover set of independent claim 1.

Accordingly, the cover set for closing a stackable container comprises a cover with at least two identical closure receiving devices and at least two closures. The locks comprise at least one hinge lock and / or at least one snap lock and / or at least one slide lock, which can be detachably mounted on the at least two identical lock receiving devices. In particular, the cover is by means of the closures on the stackable container can be releasably fixed.

A hinge lock is a lock that has a hinge so that the lid can be rotated over the hinge. The snap lock is a lock which, if it is not actuated, automatically snaps and locks. The slide lock is a lock which can be unlocked and locked by a sliding movement.

The possibility of being able to mount three different types of closure, i.e. the hinge closure, the snap closure and the slide closure on an identical closure receiving device, leads to an extremely high degree of flexibility when attaching the lid to the stackable container. The different closures can be combined with one another in the most varied of ways on a cover.

In particular, the cover has a rectangular shape with a first short side, a second short side, a first long side and a second long side.

At least one, in particular at least two, of the at least two identical closure receiving devices are advantageously arranged on the first short side and / or on the second short side and / or on the first long side and / or on the second long side.

In a particular embodiment, the cover has at least one, in particular at least two, closure receiving devices on the first short side, on the second short side, on the first long side and on the second long side.

The lid can thus be mounted on the stackable container in a wide variety of ways. For example, the closures with hinge closures can be mounted on the short sides so that the lid is stacked over the short side over the stackable one Lets the container rotate. Alternatively, the hinge locks can also be arranged on the long sides so that the lid can be turned over the long sides. Of course, locks can also be mounted on long and short sides at the same time.

The closure receiving devices and the closures are advantageously designed such that all closures are arranged flush or not protruding with the lateral outer wall of the lid, and / or all closures are arranged flush or not protruding with the top of the cover.

The flush design enables stackable containers with lids of the same design to be arranged side by side or stacked on top of one another without hindrance, i.e. even with the lid closed.

In particular, the at least two closures are injection molded parts.

The hinge lock advantageously has a plug-in device and a film hinge in order to plug the hinge lock onto the stackable container and to fix it, in particular releasably, on the stackable container by closing the film hinge.

In a particular embodiment, the closure receiving devices have a rod-shaped axle held only at the axle ends. The rod-shaped axis is thus radially exposed so that it can be easily picked up by a closure.

In particular, the snap lock has a suspension and is designed in such a way that in the assembled state it springs into the locked state if it is not actuated.

In addition, a container set is protected which comprises a stackable container and a lid for closing the stackable container. The stackable container is rectangular in shape and has a short and a long side, a stepped bottom and a container opening with a rim, so that when

Stacking the same stackable container on top of one another, the stepped bottom dips into the container opening of the container stacked below. The lid is rotatably attached to the short side of the stackable container with a hinge lock such that the stackable container can be opened by rotating the lid about the axis of rotation which is parallel to the short side.

In particular, the hinge lock is designed in such a way that the cover can be rotated through an angle of 270 ° around the axis of rotation.

The side opening of the lid at an angle of 270 ° leads to additional flexibility in handling the stackable containers.

Ways of Carrying Out the Invention

The Fig. 1 shows a perspective view of a stackable container 1. The stackable container 1 was produced by injection molding. It is essentially cuboid in shape and comprises a rectangular base 2, an opposing container opening 3, two short side walls 4 and two long side walls 5. At the top of the side walls 4 and 5 there is an edge 6 with openings 6a along the short side walls and Openings 6b along the long side walls.

The stackable container 1 can be stacked on top of another stackable container with the same construction. For this purpose, the bottom 2 has a step (not visible) so that the stepped bottom 2 dips into the container opening 3 when stacked on top of one another and is surrounded by the edge 6.

The Fig. 2 shows a cover 7, which is also a plastic injection molded part. The lid 7 can be mounted on the stackable container 1 in order to close the stackable container 1. It has a rectangular shape which corresponds to the shape of the stackable container 1. It further comprises a lid edge 8 with two short sides 9 and two long sides 10. Two closure receiving devices 11 are arranged on each side. As from the Fig. 3 As can be seen, the closure receiving device 11 is arranged in recesses in the lid edge 8. In each recess, a rod-shaped axis 12 with a round cross-section is arranged, which are fixed with their axial ends on the respective ends of the cover edge 8 which adjoin the recess. The rod-shaped axis 12 thus extends along the lid edge 8.

The outer surfaces of the rod-shaped axis 12 are exposed so that the axis 12 can be radially encompassed by closures. In other words, the closure receiving devices 13 are designed to releasably attach closures.

Such closures are in the Fig. 4 , 8th and 11 shown. The Fig. 5, 6 , 9, 10 and 12th show the locks in the assembled state. All closures shown are also plastic injection molded parts.

The Fig. 4 shows a hinge lock 14. The lid 7 can be rotatably mounted on the stackable container 1 with it. The hinge lock 14 comprises a plug-in attachment 14a, a locking lever 14b in the form of a film hinge and an axis receptacle 14c.

The Fig. 5 shows a partially assembled hinge lock 14 with a closing lever 14b that is still open. The Fig. 6 shows a fully assembled hinge lock 14 with an open cover 7. The opening angle of the cover 7 is in FIG Fig. 6 90 °.

For assembly, the plug-in attachment 14a is inserted from above into one of the openings 6a or 6b of the edge 6 of the stackable container 1. The locking lever 14b is moved from below into the plug-in attachment 14a by a 90 ° rotary movement in the direction of the arrow 14d. The hinge closure 14 is thus mounted on the stackable container 1 and encloses the edge 6 of the stackable container 1.

The cover 7 is now mounted on the hinge lock 14. For this purpose, the rod-shaped axle 12 is inserted into the axle receptacle 14c of the hinge lock 14. The assembly of this single hinge lock 14 is thus complete.

Further hinge closures 14 can be mounted on any desired closure receiving devices 13 of the lid 7 and on corresponding openings 6a and 6b of the edge 6 of the stackable container 1.

In the Fig. 6 It can be clearly seen that the hinge lock 14 is mounted and configured in such a way that the outer surfaces of the stackable container 1, the hinge lock 14 and the lid 7 are flush with one another. This is in the Fig. 6 indicated by a dashed line. In the Fig. 5 it can be seen that the hinge lock 14 is also arranged flush with the cover 7 towards the top when the cover 7 is closed. This is also indicated by a dashed line.

The Fig. 7 shows a stackable container 1 with a lid 7 mounted by means of two hinge locks 14 in a side view. The lid 7 is turned completely over the edge of the stackable container 1. The cover 7 is open at an angle of 270 °. In other words, the rod-shaped axis 12 in the present embodiment can rotate through an angle of 270 ° within the axis receptacle 14c.

The Fig. 8 shows a sliding closure 15. With it, the lid 7 can be locked and unlocked on a stackable container 1 by means of a sliding movement. The sliding closure 15 comprises an edge grip 15a, an edge support 15b, an axis receptacle 15c, a lever receptacle 15d and a closing lever 15e in the form of a film hinge.

The Fig. 9 shows a mounted sliding closure 15 which fixes the lid 7 on the stackable container 1. The slide lock 15 is in a locked state. The Fig. 10 also shows a mounted sliding lock 15, which, however, is in an unlocked state.

For assembly, the sliding closure 15 is placed on the edge 6 of the stackable container 1, ie it is pushed onto the edge 6 from the side so that the edge grip 15a comes to rest below the edge 6 and the edge support 15b above the edge 6. Now the cover 7 is mounted on the slide lock 15. For this purpose, the rod-shaped axis 12 is inserted into the axis receptacle 15c of the sliding lock 15 and the locking lever 15e is rotated through 90 ° in the direction of the arrow 15f on the lever receptacle 15d. The rod-shaped axis 12 is thus completely enclosed by the locking lever 15e and by the lever receptacle 15d.

The assembly of this individual sliding lock 15 is thus complete. Further sliding closures 15 can be mounted on any desired closure receiving devices 13 of the lid 1 and on the edge 6 of the stackable container 1.

As already mentioned, the slide lock 15 is located in the Fig. 9 in a locked state. In other words, the cover 7 cannot be removed from the stackable container 1. In order to bring the slide lock 15 from the locked state to the unlocked state, it must be pushed in the direction of the arrow 16a. After the sliding movement in the direction of arrow 16a, the sliding lock reaches the unlocked state, as shown in FIG Fig. 10 is shown.

In the unlocked state, the edge grip 15a is no longer directly below the edge 6 of the stackable container 1, but offset to the side in the direction of the arrow 16a. In this arrangement, the lid 7, together with the sliding closure 15, can be pulled upwards away from the stackable container 1. The stackable container 1 is thereby opened. In order to reset the slide lock 15 from the unlocked state to the locked state, it must be pushed in the direction of the arrow 16b.

In the Fig. 9 It is clearly visible that the sliding closure 15 is mounted and configured in such a way that the outer surfaces of the stackable container 1, the sliding closure 15 and the lid 7 are flush with one another both vertically and horizontally. This is in the Fig. 9 indicated by a vertical and a horizontal dashed line.

The Fig. 11 shows a snap lock 17. If the snap lock 17 is mounted and it is not actuated, it snaps in automatically and locks the lid 7 with the stackable container 1. The snap lock 17 comprises an edge grip 17a, a positioning bar 17b, an injection-molded spring 17c, and an axle mount 17d and an operating bar 17e.

The Fig. 12 shows the snap lock 17 in the actuated and thus unlocked state. For assembly, the snap lock 17 is pushed onto the edge 6 of the stackable container 1 so that the edge grip 17a comes to lie below the edge 6. The cover 7 is mounted on the snap lock 17 by inserting the rod-shaped axle 12 into the axle receptacle 17d. At the same time, the positioning bar 17b comes to rest on the edge of the cover 8. The spring 17c presses on the lid edge 8 from above. The assembly of this single snap lock 17 is thus complete. Further snap closures 17 can be mounted on any desired closure receiving devices 13 of the lid 7 and on the edge 6 of the stackable container 1.

The snap lock 17 is actuated by pressing, for example by means of a finger, from above on the actuating bar 17e in the direction of the arrow 18. The counteracting spring force of the spring 17c must be overcome. As a result of the actuation, the snap lock rotates approximately 15 ° clockwise from the horizontal about the rod-shaped axis 12 of the cover 7.

A position is achieved like that in Fig. 12 is shown. It is an unlocked position. In this position, the edge grip 17a is no longer located directly below the edge 6 of the stackable container 1, but rather it is offset to the left. From this position the cover 7 can be lifted upwards and thus removed from the stackable container 1. The stackable container 1 is thereby opened.

To move the snap lock 17 from the unlocked position as shown in the Fig. 12 is shown to bring back into the locked position, only the actuation on the actuating bar 17e has to be canceled. As a result, due to the spring force exerted by the spring 17c, the snap fastener 17 rotates counterclockwise around the rod-shaped axis 12 back to the horizontal, so that the edge grip 17a comes to lie directly below the edge 6.

It should be noted that the eight lock receiving devices 11 of the cover 7 can be combined with hinge locks 14, slide locks 15 and snap locks 17 in any combination. For example, two hinge locks 14 can be arranged on the two lock receiving devices 11 on the first short side, and two slide locks 15 on the lock receiving devices 11 on the second short side. Many other examples are possible. The advantage is that different closures can be mounted on identical closure receiving devices.

While preferred embodiments of the invention are described in the present application, it should be clearly pointed out that the invention is not restricted to these and can also be carried out in other ways within the scope of the following claims.
