The lip 10 is bent while being pushed onto the cone of the part 6 and snaps into the groove .12, making the lid closed in it Remained in position -

FIGS. 5 to 7 show schematically one possibility of carrying out the production method according to the invention. Assume that "the package 2 is to be made of polyethylene. The upper half 16 and lower half 18 are each made by using a sheet 30 of polyethylene which is clamped in a mold 32 which is appropriately shaped and has openings 34, which lead to a suction head 36 for generating a vacuum. The flat piece 30 is heated by a schematically indicated heat source 38 and then drawn into the shape by drawing off the air through the suction head The walls of the mold are removed and the halves 16 and 18 are then placed together ₉ with the flanges 20 and 22, as shown in Figure 6, and the flanges are connected to one another, for example, by an adhesive or by electronic high-frequency welding in the form it is to be used after joining _s it is then used for severing The lid 8 is cut through with the aid of a cutting tool 42 indicated in FIG. 7 in order to produce the final package 2 according to FIG. -

It is an advantage that a wide variety may be used of materials for manufacturing the package, for example, synthetic resins, Pappendeekel, rubber, impregnated with synthetic resin fabric and the like, "target" the packaging _in: a mold to be sold in the consumer the Cut off the lid from the container body so will; the material and its thickness are chosen ₈ that cutting instruments such as scissors and knives, the easy for the average consumer to

Are available, is easily possible. Because of its wide applicability and ease of use are synthetic resins such as Example polyethylene, polypropylene and polyvinyl chloride are preferred.

Within · the regulation that initially the packaging is in one piece is made of the container body and the lid and then the lid is separated, the manufacturing method can be broad Limits can be different * So 'the expiry according to the invention carried out in the usual injection molding and in the usual blow molding process processes that are "known and not here need to be described in more detail and with the help of which the packaging is made in one piece from the container body and the lid which can then be severed to produce the lid that can be slid over the container body * In the blow molding process and in injection molding it is not necessary to initially use a Manufacture upper and lower half, but these methods are still more expensive than the described thermoforming with Vacuum, which is also known per se.

A pack 50 according to FIGS. 9 ″ to 11 can for example be added to this used to wrap an unusual coin. The pack 50 has a lid 52 and a sliding part 54 of a container body with a recess 56 for receiving the coin. Grooves 58 and 60 in the sliding part 54 act with a circumferential lip 62 on the lid 52 together to releasably hold the lid in the fully open or in a retracted position so that the Coin can be issued.

In FIG. 10, the packaging 50 is shown before the cover 52 is separated from the sliding part 54. In this! Form she can easily be produced in the usual injection molding process ^ with the sliding part 54 and an end part 64 serving as a handle, which together form the container body, are solid and the lid 52 is purple. the Partition along a line 66 divides the cover 52 so that it can then be pushed over the sliding part 54. The package 50 can also be made by vacuum forming.

A shell packaging 70 according to FIGS. 12 "to 15 comprises one vacuum formed top half 72 with a splash. 74 »which is connected to the bundling, the pack 70 with a film 76, also with a container body 78 which has a reducing portion 80. - ' and a lid 82. The upper half 72 can, if desired be transparent or not transparent. The shrinking Part 80 has two grooves 84 and 86. The cover 82 is dimensioned so that it is dotted along the dash-dotted line after cutting drawn line 88, which runs through the hat 86, Can be pushed over the decreasing part 80 ′, as in FIG 12 is shown. The cut end of the lid 82 engages here in the groove 84, since the cut through the groove 86 causes the end to have a slightly larger diameter than the main part of the shrinking part 80 has.

FIG. 16 shows a packaging 90 with a container body 92 and a cover 94. Through a cut along one. line 96 achieved either before or after the sale to the consumer> one here again that the cover 94 can be pushed on telescopically over a sliding part of the container body 92, as shown in Figure 17 »

In the figures 18 to 20 a package 102 is shown, which has a container body 104 and a top or lid 106, each having a flange 108 and 110, respectively, around an open one Side (Figure 19). The container body 104 has a reduced size Neck part 112, which in turn has two opposite Has side flanges 114 and 115 attached to its open Adjacent side. A cover sheet 116, for example made of paper, Synthetic resin or cardboard lid can be made with an adhesive 118 with the flanges 108 and 110, but not with "the flanges 114 and 115 connected. It has a perforated line of weakness 122 centered so that it is spaced across the two having or adjacent ends of the flanges 108 and 1i0 runs, and which is interrupted by openings 124 and 126, each of which spans one of the flanges 114 and 115, respectively.
