Description

"Large-format sealed-edge pouch with hanging device"

The innovation concerns a large-format sealed-edge pouch made of composite s plastic or cellulose film with a hanging device.

Large-format side-seal bags for heavy or compact products have hardly found their way into the packaging industry due to the lack of suitable hanging devices for this type of bag.

The suspension devices known from utility models 19128S5, 1934940, 1948662, 1948663 and an older proposal by the applicant (utility model 1924344) are only suitable for smaller-format flat bags. Large-format bags equipped with such suspension devices are not secured when they are filled. The bags tear at the punched holes for hanging holes, even when using ⁺ flat reinforcement ⁺ inserts ₉ so that the bag and, depending on the degree of damage, the contents are no longer usable.

Also hanging devices of other types, such as. B. hanging loops, which, according to an older proposal by the applicant (utility model 1937268), is very good for hanging up bags of normal size are suitable, are not usable in their known type for large-format sealed edge bags, since the loops the very high loads filled bags have not grown and in most cases tear off immediately.

The innovation was therefore based on the task of creating a large-format To create edge-sealed pouches for heavy or compact filling goods, which does not have the above-mentioned disadvantages and is versatile has usable, robust and yet shapely, practical and easy-to-manufacture hanging device.

According to the innovation, it is therefore proposed that the suspension device is designed as a multiple suspension device and from There is a suspension loop and at least one perforated ring weld. The hanging loop can be pulled out between the bag walls and both in the sealed and welded seams attached to the long sides of the bag and connected to the bag walls by at least one perforated ring weld. From reinforced, flat, sealable or weldable material is therefore advantageously at least 3 areas, namely on a circular hole weld and additionally on 2 essentially straight longitudinal seam welds firmly connected to the bag material.

A lattice film is expediently used as the material for the suspension loop selected, which can also be coated on one or both sides. Because the horizontal threads of the lattice film are around the perforated ring welding When hanging up the filled large bag, a point-like load is avoided.

Is the perforated ring weld in the upper middle of the bag between Arranged between the two longitudinal sealing seams, this creates an advantageous double hanging loop made of two that are to be handled separately Loop parts formed, each of the two loop parts when hanging the bag naturally only has to carry half the weight of the bag.

Of course, within the scope of the innovation, it is just as possible to attach two such hole welding rings, one each in the vicinity of the longitudinal sealing seams of the bag, instead of one hole-ring welding arranged in the middle of the bag.

As a result, instead of a double hanging loop, only a single hanging loop is formed which has to take up the entire weight of the bag, but each loop end is doubly secured against possible tearing out, namely once by welding into the longitudinal seam of the bag and also by welding into the bag side walls with the help of perforated ring welding.

In the embodiments of the innovation concept described, it is considered to be particularly advantageous that the bag can be hung on the suspension loop as well as on the perforated ring weld _e received, because the perforated ring welding represents a second equally good suspension option. This multiple suspension device has the further advantage that, for. B. when removing the bag suspended from the perforated ring weld, this bag can be gripped on or on the suspension loop (s) and can be comfortably carried. If, on the other hand, the bag is hung on the loop (s), price, quality, advertising or other signs can advantageously be hung in the recess (s) of the perforated ring weld (s).

The multiple suspension device is useful in one of the filling » space packing-tight partitioned off piece of the bag is arranged. As a result, the filling material is passed into the area of the Suspension device excluded.

Finally, the multiple suspension device also allows a preferred adaptation to different bag suspension systems, the optionally from a hook, or from two adjacent hooks or from z. B. arranged in a triangle shape three Hooks can exist. Instead of the hook you can of course

Rails arranged in the aforementioned forms may also be present on which the large bag according to the invention with multiple suspension devices can be pushed.

It is also advantageous} the multiple suspension device for bottom filling bags to be arranged on the side opposite the filling opening of the bag because this simplifies production and filling of the bag is possible »with the addition of a harmonious room division of the bag to the shapely appearance of the commodity contributes.

Of course, it is also possible that the multiple suspension device is arranged adjacent to the bag filling opening. In this case, the bag is designed as a bottom seam bag with a side j slot-like recess immediately below the suspension device fitted. This type of bag can also be filled hanging later on delivery as an empty bag.

The drawings show a schematic representation of two preferred Embodiments of the large-format sealed edge bags according to the innovation with multiple suspension device;

FIG. 1 shows a plan view of a FlaGh bag according to the invention for bottom filling;

FIG. 2 shows a plan view of a flat pouch according to the invention for filling from the center.

A rectangular flat bag 1 is shown in FIG I _- polyamide-polyethylene composite films _s forming the bag walls 2, 2a, and are connected to each other by extending transversely to the production direction of the longitudinal sealing seams 3, 3a. Above a plane extending in the direction of manufacture seal 4- _$ defining an provided with a filling opening 5 Beutelfüllraum 6 packing tightly by a Mehrfachaufhängevorrichtung 7 'is connected between the bag sides 2, 2a an extractable carrying loop inserted in the form of a double coated with a polyethylene film mesh foil 7a are firmly connected to the bag sides 2, 2a both by the longitudinal sealing seams 3, 3a and also by perforated ring welds 7b, 7c arranged symmetrically to one another and to the longitudinal sealing seams. The perforated ring welds 7b, 7c have round recesses 8, 8a which, like the loop 7a, serve to hang up the bag.

The flat pouch 1 according to FIG. 2 corresponds to the pouch according to FIG. 1 with the difference that it cannot be filled from below but from the side and is therefore provided with an additional bottom seam 9 and a side closable bag filling device 10 through which the introduction of the product.
