Definitions

  • the invention generally relates to a container-lid combination with a twist lock, the container and lid being able to be produced from essentially flat material.
  • the invention relates to a container-lid combination with a container and at least one lid part made of essentially rigid, flat material, both the container part and the lid part having snap-in edges which are either on the inside of the lid part or on the container part.
  • Container-lid combinations made of flat material i.e. Containers with lids are known in a variety of designs, in particular also for packaging smaller objects.
  • EP 0520131 A shows a container which can be used to hold confectionery.
  • the container and its lid are provided with foldable tabs, by means of which the lid can be attached to the container.
  • Disadvantages of this solution are, on the one hand, that the outer hinged flaps do not give the container a particularly uniform appearance, and, on the other hand, that the container does not have particularly great stability against pressure loads from above, especially if it only acts on one corner, since the lid walls are in one hit the container walls at a relatively flat angle.
  • containers with a removable lid are often called felt more practical, since the lid can be placed under the container if the container is to be opened.
  • a container certainly looks more elegant than a container whose hinged lid protrudes at an angle.
  • simple slip lids often have the disadvantage that they slip very easily unintentionally from the container, either due to an elastically deformed content that pushes the lid upwards, or if the container tilts or lies on one of its side surfaces.
  • closure elements such as adhesive tapes or strapping, as mentioned in GB 1052108 A, but this has a disadvantageous effect on the manufacture and handling of the container.
  • Containers with closures which are actuated by rotary movements are disclosed, for example, in US 3973724 A, US 5165593 A and GB 2183219 A.
  • a disadvantage of these known designs is that the container opening is surrounded by a relatively high edge in the open state, so that the contents of the container are difficult to access and the interior can only be viewed to a limited extent.
  • these closures have a relatively low mechanical stability and require a significantly greater external height of the container compared to the usable height of the container interior.
  • GB 799521 A presents a cylindrical container with a bayonet lock, which has a very high stability and is also characterized by simple handling. This contrasts with the increased material and manufacturing costs, since the metal rings required for the bayonet lock must be attached separately to the edge of the container and lid. In addition, this is problematic when the container is subsequently recycled, since the different materials have to be separated from one another beforehand.
  • a rectangular container with a lid, which can be opened or locked by turning, is described in US 3027062 A.
  • the lid is locked to the container on hook-shaped projections which are provided on the front edges of the container walls.
  • the container walls are essentially made of one layer, so that the edges of the container and lid, as simple cut edges of the material, are not particularly resistant. These edges are therefore sensitive to abrasion and damage in the open state and in the process of opening or locking, since the edges of the lid slide against the edges of the container on the face or rest on extremely small contact surfaces in the closed state. Furthermore, individual areas of the edges are also unprotected on the outside of the container, even in the closed state, which can also lead to wear of these edges, for example when the container is being transported or snagging on adjacent containers.
  • the container has an optically inconsistent exterior, which seems unsuitable for storing or packaging high-quality items.
  • Another disadvantage is that the container, when closed, is not particularly stable against pressure from above, as occurs, for example, when stacking many such containers with heavier contents.
  • the container or lid walls support each other in only very small areas on the mentioned front edges. In the overlap areas near the corners, the container or lid walls meet only at a very obtuse angle, so that these areas do not provide any significant additional support Pressure from above is achievable.
  • the shape of the lid and the container are subject to certain limits, in particular the container and the lid are assumed to be identical, which is sometimes not desirable.
  • the aim of the invention is a container with a removable but lockable lid, which is easy to handle and, particularly when used as packaging, has an elegant and, if possible, flexible or significant design.
  • a locking mechanism operated by turning would be advantageous, since no separate parts are required for this and the turning movement when opening or closing the container does not require any additional manipulation by the user.
  • a container part which can be produced, for example, by folding or bending one or more blanks from an essentially flat material, such as preferably cardboard or thin plastic plates. Furthermore, a suitable cover part is provided for securely closing or reclosing the container, which cover part can also be produced from essentially flat material.
  • the lid is similar to a conventional slip lid can be placed on the container, but its dimensions are such that it can be rotated in relation to the container when placed on the container, and can thus be brought into different rotational positions.
  • the lid can only be removed from the container in one or a few specific rotational positions, while in one or a few other rotational positions it is firmly connected to the container, so that objects stored in the container cannot be lost due to inadvertent opening of the lid.
  • the handling of the container and lid is therefore comparable to that of a bayonet lock;
  • the rotary positions of the cover are therefore also referred to as “unlocked” and "locked”.
  • the described locking and unlocking of the lid is realized by snap-in edges provided on the container and on the lid, which interact differently in different rotational positions of the lid.
  • the container-lid combination in question is characterized by high stability, particularly against pressure from above.
  • An important aspect is the fact that, for example, packaging for high-quality food or luxury goods is often searched for special containers in order to present the contained product in style - this was also an essential idea in the development of the container-lid combination in question. It can be used, for example, as packaging or for storing food or luxury goods, but also generally for smaller items; sweets, confectionery, cheese, jewelry, travel souvenirs and decorative objects may be mentioned as examples.
  • latching edges are provided both on the container and on the lid, which interact with one another or not depending on the rotational position of the lid relative to the container, so that the lid can be lifted off the container in at least one rotational position, whereas it is in at least one other rotational position on the Container is fixed. Due to the bayonet-type handling of the container and the lid, the opening and closing of the container therefore corresponds to a well-known movement and in particular does not require any ready work steps.
  • the latching edges can be formed by recesses, cuts or flanging the edge either directly on the container and lid walls or on areas articulated thereon; in any case, in preferred embodiments, separate parts are not required for their production.
  • the closed container achieves the desired high mechanical stability even against pressure from above, in particular if the container walls are arranged vertically, as a container with a slip lid resting on the entire container edge. Due to the possible double-walled design of the container or lid, the edges are very stable even when open, and the lid is easier to put on. As will be shown, according to the principle of the present invention, a variety of embodiments of similarly functioning containers with lids can be produced, both in round and angular form, in particular with different numbers of corners, the number of corners of the lid not necessarily matching that of the container must match.

  • the cover part 2 is formed analogously from wall segments 23 adjoining one another via folding lines 24 and a cover plate 21 connected to them via edges 22.
  • Container part 1 and lid part 2 can each be produced, for example, by gluing together individual blanks or more preferably by folding blanks of an essentially flat material, cf. Fig. 2, wherein the necessary gluing points in the region of the wall edges 14 and 24 can be carried out by means of adhesive tabs 18 attached to these edges 12, 14, as is generally the case with folding boxes.
  • the dimensions are of the cover part 2 in relation to that of the container part 1 is chosen so large that the cover part 2 can be rotated in the state attached to the container part 1.
  • the edges 14 of the container part 1 are not, as is usual with similarly shaped containers, approximately in a line with the corresponding crease lines or edges 24 of the cover part 2, but rather approximately in the middle of a wall segment 23 of the cover part 2.
  • a wall segment 23 of the lid part 2 is shown cut open, in which area a snap-in edge 3 is visible, which in the embodiment shown is formed as the edge of an approximately triangular cutout 17 provided in the area of the container edges 14 (cf. also Fig. 2).
  • a cutout 17 is provided on each container edge 14, but this is not absolutely necessary.
  • the cutouts 17 can be produced by punching out a region of the flat material, or by an arrangement of cuts and kinks, wherein material can also be bent into the interior of the container or even completely folded over. It is only essential that the latching edges 3 are sufficiently pronounced.
  • two tabs 25 - in this case eight tabs 25 - are attached to the inside of the cover part and are connected to the wall segments 23 at edges 26.
  • the tab 25 is also cut and therefore not visible;
  • the tabs 25 have latching edges 4, which in this embodiment are formed as parts of approximately trapezoidal cutouts 27 (see also FIG. 2).
  • the locking edges 4 do not necessarily have to be part of trapezoidal cutouts 27, but can also be formed differently.
  • the tabs 25 are pressed against the container walls from the outside by the inherent tension of the material in the region of the edges 26, so that the latching edges 4 of the cover part 2 latch with the corresponding latching edges 3 of the container part 1. As a result, the cover part 2 cannot be lifted up from the container part 1 in this rotational position - The container-lid combination is thus firmly locked or closed.
  • the lid part 2 can also be pushed onto the container part 1 in the second (locked) angular position - in this case, the tabs 25 are first pressed outwards from the corner regions of the edges 16 until, as soon as the lid part 2 has been completely lowered onto the container part 1, snap into the position shown in FIG. 1b, and the snap-in edges 3 and 4 thus snap in the same way, as if the cover part 2 had first been placed in the first rotational position and then rotated.
  • a simple, in particular mechanical, closure of the container-lid combination in question is therefore possible.

  • Fig. 3 shows blanks for a container part 1 and a lid part 2 for the production of a further, preferred embodiment of the container-lid combination, which contains some extensions compared to the embodiment described in the previous figures (repeated reference numerals have been again for a better overview largely omitted).

This ensures that the cover part 2 is more securely "closed” for the user, since the user cannot turn the cover part 2 beyond the locked rotational position. Only turning in the left direction is possible in order to bring the cover part 2 into the unlocked rotational position.
