Abstract

A box (1) for substances in granular of powder form has a tear-open tongue (5) and a sprinkling device (2) which are formed from or mounted on the package. A tear-open tongue (5, 5d) is provided in a region of the box (1) which has a cover composed of several layers of cardboard and/or laminate (1a, 1b, 1c, 1d), and which is stamped out (2, 4, 5e), embossed (3b, 5c, 5b), and provided with breaking lines (5a, 3a). The tear-open tongue (5, 5d) may, if necessary, be covered by a safety tongue (3) which is torn together with the tear-open tongue (5) in order to release the contents through a sprinkling device (2) under the tear-open tongue (5).

PACKAGE WITH RIPPING HOLE AND SPRAYING ORGAN

The invention relates to a package with a flap flap and a sprinkling member, which flap flap and the scattering member 5 are formed from or attached to the package and are formed of at least two cardboard and / or separate laminate layers, are part of the package or are fastened to the folded areas from the outside inwards. provided the function of the tear flap and the sprinkling member.

10

Today, various tear flap openings are known in packages of salt, sugar, washing powder and the like. These openings are generally intended for the partial or complete emptying of the contents into separate sprinkling or dosing containers. 15

The object of the invention is to provide a repeatedly closable tear-off flap opening with a sprinkling or dispensing member, which opening is made of the packaging material itself or is attached to the package.

20

The object of the invention is achieved by a package which is characterized by what is stated in the claims.

In the package according to the invention, an additional layer cut at the spray opening is arranged between the layer 25 forming the tear flap and the layer forming the protective flap. In this case, the fastening power of the tear flap is enhanced by creating a free space between the layers. The carton or laminate of the package is punched in such a way that in particular in the area of at least one side of the package there is a multilayer shell. This is preferably formed on the bottom of the package or on the top surface of the package, which already has a shell of adhesive edges during conventional manufacturing. Normally, the shell is secured with three adhesive edges, but this number 35 may, if necessary, be further increased while the other narrow joint adhesive edges have one adhesive edge as wide as the corresponding wall of the package. In the present case, this adhesive edge 2 90644 does not have to extend over the entire length of the wall of the corresponding package. Bonding takes place along the edges of the adhesive edge.

5 The sealed, sealed package may be provided with a safety flap with a break line that can be pressed from the outside inwards, partially on top of a longer tear flap, which may extend over a single surface or over two surfaces adjacent to each other.

10

The weakening of the cross-sectional surface, which defines the cut lines of the tear flap, can be achieved by oblique incisions, as a result of which the opposite oblique of the two parallel cut lines causes interleaving, which repeatedly pushes the flap to the closed position.

The weakening of the cross-sectional area of the tear flap can be formed along its entire length by a series of oblique or straight incisions, or so that the part covering the sprinkling member is formed by straight incisions and the "fastening part" by oblique incisions. The fastening performance of the tear-off flap can be enhanced simultaneously by creating a free space between the safety flap-forming layer and the tear-off flap-forming layer by correspondingly cutting one of the intermediate adhesive edges so as to form laterally grooves adapted to press the side edges of the tear-off flap.

30 The adhesive edge covered by the tear flap comprises a sprinkling or dispensing member consisting of one or more openings calibrated according to the granularity, grain shape and quality of the contents.

According to the invention, at least one structural element, which is made of a material other than packaging, can also be formed in this area.

The invention will be explained in more detail with reference to the two schematically illustrated application examples of a package with a tear flap opening and a sprinkling member shown in the accompanying drawings.

Figure 1 shows a part applied to the plane of a housing with adhesive edges along the side, a tear flap opening in a corner of the housing and a dispensing member.

Figure 2 is a perspective view of a device according to the invention in the closed position.

Figure 3 is a perspective view of the device according to the invention in the open position.

Figure 4 is a sectional view of a device according to the invention in the region of the overhanging adhesive edges of the package.

Figure 5 is a perspective view of a device according to the invention with a flap closure and in a closed position.

Figure 6 shows a perspective view of the device according to the invention shown in Figure 5 in the open position and provided with a tear-off flap secured in this position.

Applying the package 1 to the plane reveals the adhesive edges 1a, Ib, Id, 1e, which, as shown in Figures 3 and 4, overlap in the assembled package. The assembly of the package takes place primarily along the edge area 7 at the same time. The corresponding adhesive edge le 30 is turned over the adhesive edge 1a. The adhesive edge 1a corresponding to the adhesive edge le does not have to have the same longitudinal dimension as this one. Openings 2 are formed in the adhesive edge 1a, which are covered in the assembled housing by a tear flap 5 extending over the corner of the housing; this flap is formed by a hinge line 5b, a gripping part 5d and parallel, lateral broken lines 5a formed by cutting into corresponding oblique lines.

4,90644

The adhesive edge Id covering the adhesive edge le forming the tear flap is cut so as to leave a free space between the adhesive edges le and Ib, which is preferably wider than the tear flap 5 and also a protective flap 3 which in this application is as wide as the tear flap 5. When the tear flap is repeatedly closed, it is held in the closed position by pressing against the sprinkling member 2 while its side edges protrude into the space between the adhesive edges 1a and Ib.

In another embodiment of the invention, the attachment of the tear flap head 5d is facilitated by stamping the corresponding area 5e and forming a protruding tongue 5f which secures the flap head in the closed position. Also on the outer surface of the package id (Figs. 5, 6) a stamped area 3d can be formed in the area, immediately after the breaking line 3b of the protective flap 3, in which two tongues 3c are formed to hold the tear flap 5 in the open position (Fig. 6).
