Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a self-adhesive label of the type used in resealable packaging having a peelable self adhesive surface.

It further relates to a method of making such a self-adhesive label.

[0003]

2. Description of the Prior Art Self-adhesive labels of the type described above are resealable packaging of food products such as toast bread, biscuits, and baked goods such as such, the contents of which are not consumed at one time. Used for things. The package must be resealed with the same label until empty, thus protecting the food from air, odor, and the like, preserving its physical and organoleptic properties.

Therefore, these self-adhesive labels are peeled off by the consumer when opening the resealable package,
Reused by the same consumer to seal the package. For this purpose, the label must be easy to remove without breaking or losing its ability to reapply to the resealable packaging.

In order to meet the above requirements, prior art self-adhesive labels include a grip portion formed by a peelable self-adhesive surface area that is adhesive free and has an edge portion.

[0006] This non-stick part remains slightly separated from the resealable packaging so that the consumer can easily grab it and remove the label.

However, the manufacture of this type of self-adhesive label is not necessarily difficult, but it is somewhat laborious, especially when considering industrial mass production.
It causes considerable additional cost.

Furthermore, a separating line is required to make the non-glued part and separate it from the rest of the resealable self-adhesive surface that is applied to the package.

However, this separating line can be an easy point of rupture for both the label and the wrapping paper of the resealable package, which can break and become unusable anymore.

SUMMARY OF THE INVENTION The technical problem of the present invention is to provide a self-adhesive label which overcomes the disadvantages mentioned in connection with the prior art.

[0011]

This problem is characterized in that the label comprises a structurally independent tongue which is releasably affixed to a self-adhesive surface area including an edge portion, Solved by a special type of label.

The main advantages of the self-adhesive label of the present invention are:
All of the self-adhesive surface is coated with glue, eliminating laborious and costly steps from the time of label production, yet still allowing the label to be easily grasped and peeled off.

The present invention also relates to a method of making labels as described above, wherein these labels, which are successively arranged on a retaining strip of paper material known as glassine paper, are retained from below. Characterized in that it comprises the step of cutting the strip to form a series of sections forming a tongue corresponding to each self-adhesive label.

Further features and advantages of the label according to the invention and of its method of manufacture are given below with reference to the accompanying drawings, provided by way of non-limiting example only, and toast pan resealing. It will be apparent from the detailed description of one embodiment for such an example of possible packaging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1 and 2, a resealable package is designated generally by the reference numeral 1. This is a parallel epipedal type made by a food grade sheet 3 which is appropriately semi-worked and folded so as to obtain a side lid 4 with a hanging lid 5, which is substantially envelope-like.
epipedal) wrapping paper 2.

A self-adhesive label, generally designated by the reference numeral 6, is overlaid on the droop lid 5 with a peelable self-adhesive surface 8 and an edge 9.

The self-adhesive surface 8 is substantially disc-shaped and structurally independent and is arranged corresponding to the edge 9 of the label 6 so as to include a portion of the edge 9 of the label 6. It can be peeled off and attached.

In the preferred embodiment, the tongue 10 extends beyond the edge 9.

Therefore, to open the resealable package 1,
The tongue 10 only requires gripping and pulling the self-adhesive label 6 while separating the label 6 from the hanging lid 5 of the side lid 4, thus allowing the side lid to open freely.

To close the package 1, it is only necessary to re-press the label 6 with the tongue 10 still attached.

With proper handling of the tongue 10, the package 1 can be opened by only partially peeling off the label 6, so that the self-sticking directly to the food packaging sheet 3 instead of the hanging lid 5. When only the glue on the sticky surface 8 deteriorates and as a result the glue loses its effectiveness, the tongue 10 is peeled off from the label 6 and the area of self-adhesive surface 8 with a sufficiently effective glue is removed. All you have to do is expose it. In this way, the packaging 1 can be resealed by using this new area, extending the useful life of the self-adhesive label 6 of the invention.

The intended self-adhesive label 6 has important advantages not only for its use in resealable packaging, but also for its mass production.

Labels are now commonly known as glassines and are produced in a line of retaining strips of silicone-treated paper, usually with a calender finish that has non-adhesive and toughened properties to adhesion. And first the glue is applied on the strip of paper, which glue is then applied to the label 6
Transferred to the upper surface 8 to make it self-adhesive. The glue leaves the strip without adhesive that forms the known gripping part,
One or more holding strips of longitudinally continuous strips are applied.

The self-adhesive label 6 of the invention, which has no glue-free areas on the self-adhesive surface 8, does not require a strip of glue to be applied on the holding strip 8 and is simply glue. However, it only needs to be applied uniformly along this strip, which is easier and cheaper.

In addition, the formation of the tongue 10 is also particularly simple, as will be apparent from the description of the method of making the self-adhesive label 6 of the present invention, which is carried out with reference to FIGS. 3 and 4 below. Is.

In FIG. 3, the roll-shaped sheet of label 6 is designated by the reference numeral 11. This has label 6 on it
Comprises a retaining strip of the above-mentioned paper-like material, such as glassine paper, having a surface 12 contiguous with one another and an opposite surface 13.

On the other hand, referring to FIG. 4, an unprocessed roll-like sheet for making a label 6 made by an upper sheet 16 of label paper stuck to the surface 12 of the holding strip 15. A roll of 11 'is designated by the reference numeral 14.

At the first cutting position 17, the edge portion 9 of the label 6 is cut out by the upper sheet 16, and then the second cutting position 18 is obtained.
The edge 20 forming the tongue 10 is then cut out from the opposite surface 13 of the retaining strip 15.

At this point, the excess upper sheet 16 has been removed, resulting in the roll-like sheet 11 of FIG. 3 with the self-adhesive labels 6 and their tongues 10 being subsequently resealable. It is ready to be rolled up for application onto the package 1.

The tongue 10 is thus formed directly from the glassine paper retaining strip 15 and is therefore of excellent strength.

In the preferred embodiment, the sheet of label paper 16 on top of the unprocessed strip 15 for making the label 6 is also commonly used for glassine paper, ie a roll-like holding sheet for the label. Made from the types of paper that are used.

The tear resistance of glassine paper is generally much stronger than solvent-based glues, which can have a detrimental effect on the food contained in the resealable package 1, using glue in the form of an aqueous solution. It means that you can do it.

Those skilled in the art have made numerous variations to the label construction of the present invention for resealable packaging and are within the scope of the present invention as defined by the following claims. Obviously, certain attendant things can be fulfilled without deviating.
