Description

a) The two longitudinal flaps (3, 4) have auxiliary perforations (10) which run across these longitudinal flaps (3, 4) at a distance (X) from the lateral edge of the longitudinal flap which is smaller than the length (Y) the side flaps (5) (see Fig.l).

b) The shortened longitudinal flap (4) is with the side flaps (5) only glued in the area between the box edge (15) and the auxiliary perforation (10)

c) The fully formed longitudinal flap (3) is in between with the other flaps (4,5) only in the area the free box edges (15) and the auxiliary perforations (10) or between the Longitudinal flap edge and the nearby perforation of the tear strip (9) glued.

d) The tear strip (9) is completely covered by the shortened longitudinal flap (4)

e) The shortened longitudinal flap (4) has two vertical punchings on the free longitudinal edge on.

f) Following the auxiliary perforations (10), there are auxiliary perforations on the longitudinal walls (1) (14) arranged, which run to the respective adjacent vertical Schachielkanten, wherein these points of intersection are connected by grooves (13) on the side walls (2).

2. Resealable, tubular, pre-folded folding box with bottom and top flaps with a tear strip and an insertion tongue, which are arranged on the longitudinal flaps of the lid, wherein one of the longitudinal flaps has the width of the side walls and the other longitudinal flap on the other hand is significantly shortened, characterized by the combination of the following features:

a) The two longitudinal flaps (3, 4) have auxiliary perforations (10) which run across these longitudinal flaps (3, 4) at a distance (X) from the lateral longitudinal flap edge which is smaller than the length (Y) of the side flaps ( 5) (see Fig. 4).

b) The shortened longitudinal flap (4) is with the fully formed longitudinal flap (3) under recess of the tear strip (9) stuck together.

c) The fully formed longitudinal flap (3) is with the side flaps (5) only in the area between the free box edges (15) and the auxiliary perforations (10) glued.

d) The tear strip (9) runs on the shortened longitudinal flap (4), approximately in the middle of one narrow edge to the auxiliary perforation arranged in the vicinity of the other narrow edge (10).

e) The fully formed longitudinal flap (3) has one between the two auxiliary perforations (10) Punching running parallel to the free edge and located behind the tear strip (9) with a tongue (20) and lateral latching tongues (21).

f) Following the auxiliary perforations (10), there are auxiliary perforations on the longitudinal walls (1) (14) arranged, which run to the respective adjacent vertical box edges, wherein these points of intersection are connected by grooves (13) on the side walls (2).

The invention relates to a resealable, tubular, pre-folded folding box with a bottom and lid flaps with a tear strip and insertion tongue, which are arranged on the longitudinal lid flaps are, wherein one of the longitudinal flaps in each case has the width of the side walls and the other longitudinal flap in contrast, is significantly shortened

From US-PS 40 72 263 it was known for the purpose of saving material to form blanks and in to arrange a web of material that shorter tabs are in engagement with longer tabs.

Furthermore, a folding box of the above type was known from DE-AS 12 39 234, however provided that the cardboard material is coated with wax. This coating should be suitable for the folding box make for packaging frozen food, ice cream, etc. The possibility of resealability This Faltschachti is based on the fact that the gluing of the to be separated from each other when opening Box parts can be solved relatively easily through the wax layer. If the wax layer would be missing so the folding box would only be opened by destroying the corresponding box parts can be, a fact that practically the resealability the folding box excludes

The invention is based on the object of the known To improve folding box so that when achieving a powder-tight lid closure a large Lid opening is achieved, which allows convenient removal of the contents.

One solution to this problem is as follows:

a) The two longitudinal flaps have auxiliary perforations that run across these longitudinal flaps in one Distance from the side edge of the longitudinal flap, which is smaller than the length of the side flaps.

b) The shortened longitudinal flap with the side flaps is only in the area between the box edge and glued to the auxiliary perforation.

c) The fully developed longitudinal flap is with the other flaps only in the area between the free Box edges and the auxiliary perforations or between the edge of the longitudinal flap and the adjacent one Perforation of the tear strip stuck.

d) The tear strip is completely covered by the shortened longitudinal flap.

e) The shortened longitudinal flap has two vertical punchings on the free longitudinal edge.

f) Following the auxiliary perforation, auxiliary perforations are arranged on the longitudinal walls to the nearby vertical chess
