Abstract

The paper bag has a block bottom in the fold (1) of which is a T-shaped closure part (2) forming a carrying handle (3). The closure part's (2) two T-arms (4) are stuck onto the base flap (5) of the folded base (4). Lengthwise flaps (6,7) of the base fold (1) are stuck onto these T-arms (4). The two lengthwise flaps (6,7) are at least the same width as the T-arms (4) of the closure part (2). A reinforcement sheet (8) is stuck underneath the T-arms (4) into the closure part (2) at least and preferably in the carrying handle (3). ADVANTAGE - The biodegradable paper bag is suitable for packaging flexible, compressed articles.

Description

The invention aims to create a paper bag Cross bottom to hold a wide variety of products, with the the cross bottom in a material-saving manner with a simple Carrying option is designed.

This object is achieved by the characterizing Features of claim 1 solved, the in the design features listed in individual subclaims advantageous and beneficial further training of Represent task solution.

The paper bag with a cross bottom is in the conventional Kreuzboden a separate striker with handle introduced, which is glued to the bottom flaps and by the longitudinal tabs of the bottom fold is taped over, so that this Locking part on the one hand with the bottom fold in the cross bottom closes in a stabilizing manner and on the other hand at the same time one protruding from the Kreuzboden Carrying handle results.

The handle can be transported or stacked Place the bag flat on the bottom of the cross and carry it Fold up the bag.

The striker is a simple T-piece from one Paper sheet with / without internal reinforcement (sheet or  Cardboard insert) inexpensive to manufacture and efficient in Cross floor fixable.

This paper bag is particularly suitable for Packaging of flexible, compressed articles that are in compressed form can be seen, which by a Bag opening tear tab is enabled.

The entire paper bag is a single-use packaging, which is biodegradable after being thrown away.

In the drawings is an embodiment of the invention shown, which is explained in more detail below. It shows:

Fig. 1 is a perspective view of a paper bag with block bottom and glued in the cross bottom closure member with carrying handle,

Fig. 2 is a plan view of the blank of paper bag,

Fig. 3 is a plan view of the flattened paper bag with open cross bottom,

Fig. 4 is a plan view of the T-shaped closure member,

Fig. 5 is a plan view of the flattened paper bag with glued in the cross bottom closure member,

Fig. 6 shows a cross section through the paper bag according to section line II in Fig. 5 with the locking part glued into the cross bottom with internal reinforcement.

The paper bag with a cross bottom has in its bottom fold ( 1 ) an inserted, T-shaped closing part ( 2 ) forming a handle ( 3 ), which is glued to the bottom fold ( 1 ).

In this case, the closing part (2) is glued with its two T-legs (4) on the bottom flaps (5) of the bottom fold (1) and to this T-limb longitudinal tabs (6, 7) of the bottom fold (1) are glued (4) , so that the closing part ( 2 ) with its two T-legs ( 4 ) is fixed as a separate part in the bottom fold ( 1 ) and closes the cross bottom.

The two longitudinal tabs ( 6 , 7 ) of the bottom fold ( 1 ) have a width which corresponds at least to the respective width of the T-leg ( 4 ) of the closing part ( 1 ).

The closing part ( 1 ) is formed from a sheet of paper which is formed in one piece with the T-shaped closure part ( 2 ) which is doubled in the carrying handle ( 3 ) and which has the two T-legs ( 4 ) projecting on both sides of the carrying handle.

A reinforcing sheet ( 8 ) made of paper, cardboard or the like is glued into the closing part ( 2 ) at least in the carrying handle ( 3 ), preferably in the carrying handle ( 3 ) and under the T-legs ( 4 ); the reinforcement sheet ( 8 ) is also double in the double-walled handle ( 3 ) and, like the closing part ( 2 ), has a T-cross section.

The carrying handle ( 3 ) shows a punched hole in the handle ( 15 ), through which a wall area which can be shaped out of the handle wall ( 3 , 8 ) and forms a handle opening is formed.

The locking part ( 2 ) with its T-legs ( 4 ) takes up at least almost the entire cross base length.

A tear-open tab ( 11 ) protruding from the longitudinal seam ( 9 ) and formed by a sheet is glued into the longitudinal seam ( 9 ) of the bag blank ( 10 ), in the area of which perforation lines ( 12 ) extend at least on a portion of the bag circumference.

This tear-open tab ( 11 ) enables the sealed bag to be opened and the packaged product to be removed.

From FIG. 1, the finished and filled paper bag with the inserted into the bottom fold (1) closing part (2) is visible, wherein the carrying handle (3) is raised up out from the bottom fold (1). The tear-open tab ( 11 ) is shown in dash-dotted lines, the handle part ( 11 a) of which protrudes from the longitudinal bag seam ( 9 ).

Fig. 2 shows the bag blank ( 10 ) with the bottom flaps ( 5 ) and longitudinal flaps ( 6 , 7 ) foldable by cut lines ( 16 ) and fold lines ( 13 ) relative to the blank ( 10 ) to the cross bottom; ( 13 a) represent the fold lines for forming flat bags, ( 9 ) is the longitudinal seam and ( 14 ) the edge strip that can be connected by gluing.

The tear-open tab ( 11 ) formed by a sheet is glued onto the blank ( 10 ) and protrudes from the longitudinal seam ( 9 ) and later from the longitudinal seam ( 9 ) and the edge strip ( 14 ) connected to it with its grip part ( 11 a). The cut ( 10 ) has perforation lines ( 12 ) in the area and subsequent to the tear tab ( 11 ).

Fig. 3 shows the circumferentially closed and flat-lying bag, in which the bottom fold ( 1 ) is open; the two opposed bottom flaps ( 5 ) are folded into the bottom cross-section and the longitudinal flaps ( 6 , 7 ) are folded outwards. The closing part (2) of FIG. 4 is affixed in the locations (17), with its T-legs (4) on the two bottom flaps (5), so that the T-leg (4) close the open cross-bottom. Then the longitudinal tabs ( 6 , 7 ) are folded onto the glued-on T-legs ( 4 ) and also glued to them.

The one longitudinal flap ( 6 ) extends only on one T-leg ( 4 ) and the other longitudinal flap ( 7 ) on the other T-leg ( 4 ) and with a flap part ( 7 a) widening it also on one side of the handle ( 3 ), as shown in Fig. 6.

There is also the possibility of making both longitudinal tabs ( 6 , 7 ) of the same width so that they only cover the T-legs ( 4 ) and are glued to them, the flap part ( 7 a) then being cut off during cutting ( 10 ) got to.

Fig. 5 shows the flat-lying bag with the bottom part ( 1 ) inserted and glued closing part ( 2 ).

Fig. 6 shows in cross section the gluing of the closing part ( 2 ) with its T-legs ( 4 ) on the bottom flaps ( 5 ) and under the longitudinal flaps ( 6 , 7 ) and the handle ( 3 , 7 ) projecting from the longitudinal flaps ( 6 ) with internal reinforcement ( 8 ).

In order to obtain a larger adhesive surface for the closure part ( 2 ) with the handle ( 3 ), which is advantageous for reasons of stability and the shear forces that arise when the paper bag is carried, there is the option of using the two bottom flaps ( 5 ) in the adhesive points ( 17 ) to fix additional paper sheet ( 18 ) corresponding to the bag width, whereby the still open floor is covered. Then the closure part ( 2 ) is glued to the two longitudinal tabs ( 6 and 7 ).

In Fig. 3 the additional paper sheet ( 18 ) is shown in dash-dotted lines in the part.
