DE7807824U1 - Heat-insulating box with sealed protective cover - Google Patents

Description

The subject of the utility model is a thermal insulation Box, especially for ice creams, with a vsr: sealed protective cover that gives the buyer the Guarantees an unopened package. Conventional heat insulating boxes are common cuboid and consist of an actual box with an adapted lid. This conventional When the lid is closed, boxes take up as much space when empty as when they are filled; with open Lid they need even more space. It is also used, especially in the large-scale Self-service retail, more and more necessary to design such packaging so that for the consumer it is guaranteed that the box has not been opened since production has been. This is also necessary in order to

and supervisory staff a control option and to prevent that something within the self-service area that is normally in the The goods contained in the packaging are exchanged for more expensive goods. On the other hand, such Vereiegolungen must be easily removable in the interests of the consumer.

Such "seals" today usually consist either of a bonded paper envelope of the entire rectangular box, on which an image of the product contained in the box is printed, or instead of or in addition to this paper sleeve in a transparent, welded one Film that must be completely torn off before the paper sleeve is removed and the box opened can be. In addition, there is the following: ice creams are usually first filled into cardboard boxes by extrusion, their cuboid Due to this type of filling, the exterior takes on a kind of soap shape because the walls bend. For this reason, heat-insulating boxes must be provided, the inner dimensions of which are larger Bind as those of the inner pre-packing cartons so that the insulating boxes close well. This results in an undesirable loss of space.

The present invention aims to avoid the disadvantages of conventional packaging. The invention relates to a thermally insulating box with a sealed protective cover that is

by a combination of two symmetrically assigned, identical half-boxes made of insulating material with a thin, tearable lid that in turn on at least two symmetrically opposite edges of one of the half boxes is attached and connects both half boxes, these half boxes stacked in and through Joining can be closed.

In a preferred embodiment, the half-boxes generally the shape of a truncated pyramid with a rectangular cut, the top through a flat lid is closed, while the edge of the base is surrounded by a bead, "which tapers at two opposite corners in an edge spring, each extending over the Half of the opposite longitudinal and narrow sides extend. Form when joining two of these identical half boxes a box in the form of two truncated pyramids joined together at the base. A seamless edge is created here by the fact that the feathers on the edge of each part box each overlaps over the edge part of the other part box which is not provided with a spring and flush with the beaded edge. In such a box, the folding lid, the top and two opposite sides of the pyramid stump of one of the two half boxes as well as the encompass corresponding sides of the bead and the springs of the assembled half-boxes and on Edge of the lower half box below the bead

be glued. It is also possible that the folding lid covers the entire truncated pyramid "of the upper half-box and over the edge bead and the pushed together Feathers is pulled down on the two long sides and on the lower edge of the bead is glued to the two long sides of the lower half box. It is possible to run along the folding lid the bulge line of the lower half box with a series of interrupted incisions to the later Tear open the box. In this way, the folding lid only covers a little more than half the box, but offers enough space for illustration and adequate protection against unauthorized persons Open at a much lower total price than conventional sealed protective covers.

In a practical production example that is particularly good for packaging ice creams suitable consists of the box according to the invention of two half boxes, which are either made of expanded, made of pressed polystyrene foam or a corresponding heat insulating material as well as from one Lid made of cardboard or similar tearable material.

The " The following detailed description and the accompanying drawings, which are exemplary and not finally, a way of realizing the invention represent.

truncated pyramidal or trapezoidal part 2, 2 ¹ , the surface of which is closed by a flat lid and the lower edge of a bead 3, 3 ¹ with triangular ;. Cross-section is formed, which extends into two diagonally opposed springs k, 5, each running around a quarter of the total circumference. If a half box is turned over in order to be joined with an identical half box, as shown in Fig. 2 by the arrow 6, the springs k, 5 »^ 'j 5' close together seamlessly and form 3i 3 by being inserted into the bead * a seamless edge, in that the respective feathers enclose the upper edge part of each half box and sit on their bulge. This ensures good thermal insulation. The truncated pyramid shape of the two same half-boxes enables them to be plugged into one another, as shown in FIG. 1 and FIG. 2 through, whereby a storage space gain of the order of 60 % is achieved compared to the conventional rectangular boxes. When closed, the box has a cavity inside, the shape of which adapts practically without loss of space to that which occurs when ice cream is injected into rectangular cardboard boxes. Storing the filled boxes therefore does not require more space than the conventional rectangular boxes, because their shape, which is better adapted to the content, allows overall small dimensions for the same content.

A lid is placed on these boxes, which are formed by joining two identical halves, before they are discharged. It is caused by the fact that a section 7, is folded h at the edges according to the figure and glued as shown in Figure 3, so as a truncated pyramid for covering the pyramidenstumpfförmi £ / 2n upper part 2 is the shape of a half box. This truncated pyramid-shaped part 8 is extended over the two opposite longitudinal sides by two edge strips 9-10, which are connected to the pyramid part by two tear-off strips 11, 12 cut in a herringbone pattern. On the finished box shown in Figure 5, the edge strips 9 _f 10 are glued under the bead 3 ^{1 of} the lower box, the pyramid-shaped part of the folding lid 8 completely covering the corresponding upper part 2 of the upper half-box. The tear-off strips 11, 12 run along the springs 4, 5, V, 5 'and are therefore easy to grasp. Such a cover cannot be opened without authorization; The integrity of the packaging can easily be checked. '

Of course, the invention is not restricted to the exemplary embodiment described. in the Rather, the scope of the invention, depending on the type of use, includes numerous modification options, which are readily available to those skilled in the art. For example, the narrow sides can be on the folding lid can be omitted so that the folding lid only covers the top, the two long sides of the pyramid
