Container or bag

The present invention relates to containers or bags. ___ especially those for holding cold or hot materials and a method for producing the same. / ·

Such bags and containers are known per se .. · DIE but so far ■ known mostly suffered from numerous disadvantages, such as lack of strength, difficulty closing "and often quite expensive method of production" are the new container .. '/' or bag correct these disadvantages.: ■

The new bags or containers are made of thermoplastic Plastics, e.g. from a film, hose or multilayer Materials. If the container is e.g. from a; Söh3.auc.h \ produced, the tube is folded in such a way that one side protrudes slightly, thus creating an edge. Dana..will .the Bag or container cut out of the material by heat fusion so that the side walls of the 'actual

_ 2 -

Container part and the side walls of the neck part as well as -the o "bere edge of the container sealed by a heat fusion seam (or limited). The lower edge of the container * ters as well as the lower edge, on the neck part, where the "double layer ends, as well as the upper edge of the neck part exist only from the columns formed by dal Faltea ^ - ""; ■;

If, for example, a film is used instead of a hose, it must be folded once more to get to the same container ■; '... and the upper edge of the neck part has to be provided with a heat fusion seam. ■ "., ..,

Of course, materials with more than two layers can also be used, or more than ■ -.- ■ ". Can be folded twice. ■ _; ^r

Means are then attached to ensure that the bags or containers are properly sealed. For example, an adhesive strip can be attached to the end of the neck part or the beginning of the container part, which is initially protected by a cover layer. By folding the Hall hatchet and / gluing the folded neck with the adhesive strip, a firm seal can then be achieved. Likewise, on the upper part of the neck, a - ^; Strips made of a relatively strong material can be attached, which is provided with a snap fastener (eg snap fastener) ^: -. After rolling up the neck, this'

For the production of the bag, the thernioplas t is before material; \ V "either self-made or bought in the form of a .tube -unlimited- ^:. Greater length. Such a .tube-shaped base material 13 is shown in Figure 5. This tube is laid flat— and roughly in the middle (see Ϊ4) folded in such a way that one edge lies somewhat below the other edge and in this way the extension .12 of one side of the neck, shown in Fig. 6, arises. From Fig. 9 it can be seen that the so folded 'tube.' On one side of the container part has foils or layers 45 and 16 and on the other side foils or layers 17 and 18- ^ g. The bottom edge of the bag is formed by the fold line H, and it can be clearly seen that the Side parts of the pouch attached to the neck piece by a fe ^ i-r9-wna-enT ^ r ^ triiffiuisr ^ s; · © FaIte ^ and not

These flaps serve - as also described above .- ■ together with. a cord" 4 in addition -, .. _: - to hold the bag in a certain position. If each side of a bag has two layers (see Fig ... 9), these '■' .. flaps consist of four layers of material and are: therefore sufficiently strong. *;

It is particularly pointed out that if the same heat fusing form is used, bags of different depths, however: onit. of the same width, can be made, -lie indicated by the dashed lines 26 and 27, bags can be made with the same shape., of different depths. A bag with a container part measuring 20 x 27.5 cm requires a plastic tube with a diameter of. 57.5 cm; -a bag with a size ", -of 12.5 × 27.5 cm, a tube with a diameter of 45; cm, .- / .. and a bag with a size of 7» 5 x 27 »5 cm a hose "· with. \ -, - a diameter of 35 cm.

However, it is often very desirable for this pail to have the. Inventively measured bags with simple thermal insulation .; to provide. It can be seen from FIGS. 12 and 13 that a simple cover layer 36, which covers both sides of the bag, can be placed around the lower part of the bag. This cover layer 36Y can be made of. imitated chamois, but preferably a layer of material made of extremely thin, compressed layers of cellulose wool is used. This top layer can be used in any way. connected to the bag, in most cases the pressure of the heat fusion mold is completely sufficient. -. . . _{^.Y: ■;} '
