Definitions
- the invention relates to a gusseted bag made of flexible weldable material, with a closed bottom end and one with an internal resealer provided head end, with the between the two the bag front wall and the bag back wall forming side gussets inlaid on both sides extend from the bottom end to the head end and with one Distance below the top edge of the bag walls ends and thereby a side wrinkle-free head area of the Define the bag in which the resealer is formed between the two bag walls.
- the invention has for its object a gusseted bag to create the type specified at the beginning the simple way in the course of the bag production under Avoiding an increased cost of materials a closure the upper ends of the gussets is formed, which at the same time no adverse influence on the filling and Emptying properties of the bag increases.
- the welding of the upper gusset ends with itself itself can depend on the nature of the material the bag in a simple manner by attaching a closure weld preferably in the area of the upper, possibly cut edges sloping towards the bottom Side gusset ends occur between their two layers of material, or it becomes an upper area of the ends of the gussets on one of the two halves of each gusset folded over, and the welding of the gusseted end with itself with the folded end and the adjacent gusset half formed.
- the arrangement of the reclosure device in the gusset-free allows for its easy Attachment e.g. through a welding process in the manufacturing process of the bag.
- the reclosure facility can therefore e.g. in the form of snap fastener tapes made of thermoplastic in the of flat bags familiar way on the inside of the bag be attached.
- Such press fastener tapes with tongue and groove in mutual locking engagement bringable locking members are known per se.
- the reclosure device can, however, also be used for bags be formed by fastener tapes, which are called Velcro fastener tapes or designed as a slide or zipper are.
- a reclosure device that of one that extends across the bag width, on the inside of the bag front wall and / or the strip applied to the back of the bag permanent adhesive or pressure sensitive adhesive formed is.
- This freedom of choice in the design of the reclosure device is with the bag according to the invention given that the reclosing device completely regardless of the closure of the upper gusset ends arranged in the gusset-free head area of the bag is.
- the gusseted bag shown in the drawing can as a plastic bag of film material made of thermoplastic Plastic, especially a polyolefin like Polyethylene or polypropylene, or as a composite bag from be formed from a composite material that at least its inside allows welding Layer of thermoplastic wears while one or more layers adjoining the outside a metal foil of the composite material as an intermediate layer, e.g. Aluminum foil, for the aroma tightness of the bag can have.
- thermoplastic Plastic especially a polyolefin like Polyethylene or polypropylene
- the bag shown includes a closed one Bottom end 1 and a head end 2, which is empty of the bag according to FIG. 2 is open at the top and only after filling the bag in the filling mode along the upper edge 3 of the bag walls 4 and 5 by a Weld 6 is closed, as in the filled 1 comes to the illustration.
- the bag wall 4 forms the bag front wall, while the Bag wall 5 forms the back wall of the bag.
- gussets 7 inserted on both sides, which are from the bottom end 1 extend towards the head end 2 and at a distance below the upper edge 3 or the weld 6 of the bag ends.
- the bag walls 4 and 5 is thus a gusset-free Head area 8 of the bag created.
- the head area 8 there is a reclosing device 9 formed between the two bag walls 4, 5, which at the example shown two over the bag width extending closure straps 10, one of which on the bag front wall 4 and the other on the bag rear wall 5 attached by welding or heat sealing is.
- the fastener tapes 10 are, for example as congruent snap fastener tapes with in the manner of Tongue and groove can be brought into mutual locking engagement Locking members 11 formed.
- the reclosure facility 9 is removed by the consumer after a disconnection the weld 6 used.
- the gussets 7 include on both sides of their middle Folded edge 12 each two side fold halves 13 and 14, the along side welds 15, 16 with the bag front wall 4 or the bag rear wall 5 are connected. In the head region 8, the weld seams 15, 16 settle on both sides in each case as a weld seam 20.
- the empty state 2 are the two side gusset halves 13, 14 each gusset 7 slightly V-shaped flat against each other while they are filled 1 opened by flat spreading to the outside are around the filled bag in its filling area to give an approximately parallelepipedal shape.
- the upper end region 17 is the Side folds 7 folded along a fold line 19, the from the outer edge defined by the side weld 15 the gusset half 13 goes out and to the bottom end 1 runs obliquely.
- the folded end region 17 each gusset 7 has the shape of a right-angled Triangle, the hypotenuse according to the angle of inclination the folding line 19 more or less obliquely to the bottom end 1 is directed.
- the closed bottom end 1 can have any configuration received according to the purpose of the bag and for example the flat one shown in FIG. 1 End weld 21 have.
