United States Patent 6 Claims cl. 229-51 ABSTRACT OF THE DISCLOSURE A tear-up package, especially for food products, such as chocolate, candy and like small articles consists'of' an inner envelope in which the products are wrapped and an outer envelope surrounding the inner envelope. The outer envelope has formed thereon a tear-up portion which adheres to a portion of the inner envelope, so that when the tear-up portion is torn open, the adhering portion of the inner envelope is also torn open and the products wrapped by the inner envelope become exposed.

This invention relates to tear-up packages especially for food products such as chocolate, candy and like atticles. The package is of the type in which the products are wrapped into an inner envelope which is surrounded by an outer envelope. In such packages, in order 'to take out some of the contents of the package, for example some pieces of chocolate, it is necessary to first open the outer envelope and then to pull the inner envelope partly out of the opened outer envelope in order to be able also to open the inner envelope. The opening of packages of the mentioned type accordingly is relatively awkward. Even if an outer envelope of the tear-up type would be used, the inner envelope would still have to be separately opened, so that opening of the package would not be substantially facilitated.

Accordingly, it is an object of this invention to facilitate opening of a package in which the packed articles are wrapped in an inner envelope which itself is wrapped in an outer envelope. According to the invention, the outer envelope is formed with a tear-up portion which is firmly adhering to the portion of the inner envelope situated immediately below the tear-up portion, whereby upon tearing away the tear-up portion of the outer envelope, said portion of the inner envelope situated below the tear-up portion will also be torn open. In this manner, when the package is torn open by exertion of a pull on the tear-up portion of the outer envelope, the contents of the inner envelope will be exposed at the same time and can be taken out of the package.

A preferred embodiment of the invention is illustrated in the accompanying drawings, in which FIGURE 1 is a perspective view of an interior envelope containing a layer formed by a plurality of small chocolate tablets arranged to the shape of a usual chocolate square or bar, the outer envelope being shown in dash and dot lines.

FIGURE 2 is a top plan view of a blank of the outer envelope.

FIGURE 3 is a perspective view of the finished package ready for sale.

FIGURE 4 is a similar view after tearing up the package.

Referring to FIGURE 1, a number of single chocolate tablets 1 are arranged to the shape of a one-layer chocolate bar on a rectangular supporting sheet having a bottom 2 and upturned longitudinal side flaps 2a. The tablets 1 together with the supporting sheet 2, 2a are wrapped into aninner envelope 3 of tin foil. A strip of adhesive 4 extending over the area of several tablets 1 is applied to 3,389,852 Patented June 25, 1968 the .top face of the-tin. foil envelope 3, for example :by a nozzle effecting a to-and-fro movement at=the adhesive applying station of 'any'conventional wrapping machine. Afterwards an external carton 5 is wrapped about the-bar consisting of the chocolate tablets 1, the-supporting sheet 2, 2a and the inner envelope 3.

The blank of .the external carton-5 is shown in:.FIG-

I U-RE 2.v This blank comprisesa top part-" and a bottom part 11. The top part 10 is connected along-a folding line 15 to a side flap 12, and this latter is connected along a folding line 14 to a bottom closure flap 14a. The top and bottom parts 10 and 11 are connected toeach other by a side flap 13 along folding'lines 16 and 17. End flaps 18 and19 are connected to the top part '10 along folding lines 20 and 21, respectively. 'End closure-flaps 22 and 23 are connected alongfolding lines 24 and 25 togthe end flaps 18 and 19, respectively.

A tearing portion 6 is formed on the top part 10 of the blank. This tearing portion starts from the folding line 20 between the top part and the end flap 18 and is defined by a curved weakening line 7 extending inwardly from one end of the folding line 20 and across the top 7 part 10 to a point 24 adjacent the folding line 15 between the top part 10 and the side flap 12, and by a weakening line 8 extending along the folding line 15 from the other end of the folding line 20 to a point 25 intermediate the length of theside flap 12. Between the points 24 and 25 of the blank, the material of the blank is out along the line 9, the cutting line 9 slightly passing beyond the folding line 15 in the material of the side flap 12. In this manner, when the blank is erected to form the carton 5, a tearing flap 26 is formed which slightly projects laterally beyond the side flap 12 of the carton as will be seen from FIGURES 1 and 3.

When the carton blank is wrapped about the inner envelope 3, the tearing portion 6 will be situated above the adhesive strip 4 on the top of the envelope 3 and will firmly adhere at this region to the portion of the envelope 3 provided with adhesive.

For opening of the package, the flap 26 is seized with the fingers and the portion 6 torn open. As illustrated in FIG. 4, when the portion 6 is torn away a portion of the top part 10 of'the envelope 3 adhering to the portion 6 side flaps could be formed as a tearing flap and could be made to firmly adhere to a corresponding portion of the inner envelope in the finished package. The connection between the tearing flap and the inner envelope could also be obtained otherwise than by adhesive, for example by tacking or stitching the flap to the inner envelope.

I claim:

1. A tear-up package for food products of the type in which the products are wrapped in an inner envelope surrounded by an outer envelope, in which the outer envelope is formed with a tear-up portion which is firmly adhering to the portion of the inner envelope situated immediately below the. tear-up portion, whereby upon tearing away the tear-up portion of the outer envelope, said portion of the inner envelope situated below the tearup portion will also be torn away, said tear-up portion laterally projects beyond said package to facilitate the opening of said package.

2. A tear-up package according to claim 1, in which said tear-up portion is formed at one side of the top portion of the outer envelope and is defined by a curved weakening line extending from one edge of the package across said top portion, and by a weakennig line extending along an edge of the package.

-A--tear-up package accordingtoclaim 1 ,-in whichsaid tear-up portion is provided with a projecting flap.

4. A tear-up package according to claim 1, in which said tear-up portion is bonded to said portion of the inner envelope by adhesive. z a

- 5. A tear-up package according to claim 4 for packaging a'plurality of chocolate tablets to the shape of a single layer chocolate bar, in which the adhesive is applied to the top face of the inner envelope and extends over the area of several chocolate tablets.

6. A tear-up package according to claim 1 and comprising an outer envelope formed by a folding carton of rectangular shape having top and bottom parts, side flaps and end flaps, said tear-up portion being formed in the top part of the carton and extending inwardly from one of the small sides of the rectangular top part, said tear-up portion being defined by a curved weakening line extending from one corner of said top part at the end of said small side across the top part into proximity of the 0p posite-longitudinaledgeofthe top part, by a straight weakening line extending from the opposite end of said small side along said opposite longitudinal edge of the top part to a point situated intermediate the length thereof, and by a tear-up fiap extending between said point intermediate the length of said opposite longitudinal edge and theend of said curved weakening line in proximity of said longitudinal edge, said tear-up'fiap having been formed by a cutting linemade in the material of the side flap joining said opposite longitudinal edge whereby the tear-up fiap laterally projects from said side flap.
