Description

A self-adhesive label for packaging with reusable closure.

The present invention is related to a packaging with reusable closure including a label self-adhesive that has a detachable self-adhesive surface.

The invention relates more specifically to packages with reusable closure such as those used, by example, for food products, cooking products such such as bread, cookies and the like, whose content is not consume at once. Until the content runs out, the package it must be closed again, with the same label, thus protecting the air feed product, odors and the like with the in order to preserve its physical and organoleptic properties.

These packages are provided with labels self-adhesive that are therefore intended to be peeled off by the user at the time of opening the closing package reusable and reused, by the same user, to close the package. For this purpose, the label must be able to be removed easily, without tearing it and without losing its ability to stick New to reusable closure package.

In order to satisfy the above requirement, Self-adhesive labels of prior art are provided of a grip part defined by a surface area detachable self adhesive that is free of adhesive and includes a part of separation. Reference can be made for example to EP-A-0 545 136.

Since this part is not stuck, it remains slightly separated from the package with reusable closure so that the consumer can easily grab it and remove the label.

However, although the production of this type of Self-adhesive labels is not exactly difficult, it is in fact laborious way and, particularly where it comes to production Industrial mass, is the cause of extraordinary costs not despicable.

In addition, the presence of a line of separation to define the adhesive free part, separating it from the rest of the self-adhesive surface that is attached to the package of reusable closure.

However, this separation line can constitute an easy break point, both for the label that It can tear and stop being reusable, as for the wrap of reusable closure package paper.

The technical problem of the present invention is provide a reusable closure package including a self-adhesive label that overcomes the mentioned disadvantages related to prior techniques.

This problem is resolved with a package that has a label of the type specified in the claim one.

The main advantage of the self-adhesive label of the invention is that the self-adhesive surface is completely covered with adhesive, thus eliminating the laborious and expensive label production steps, while It allows you to easily grab the label and remove it.

Other features and advantages of the label according to the invention will become obvious after the description detailed one embodiment, set forth herein with reference to the accompanying drawings, provided merely by way of example not limiting and referring in this example to a package of reusable bread pan closure.

In the drawings:

Figure 1 is a perspective view of a Reusable closure package closed with an agreement label with the invention:

Figure 2 is a perspective view of a Figure 1 package open;

Figure 3 is a view of a certain length of a roll sheet of labels according to the invention; Y

Figure 4 is a schematic illustration of a method for the production of the sheet of figure 3.

Referring to figures 1 and 2, the Reusable closure package is usually indicated with the number 1. It has a parallelepiped wrap 2 consisting of a sheet 3 with quality for food that has been properly cut and folded so that a closing side 4 is obtained, substantially as an envelope, which includes a flap 5.

A self-adhesive label, usually indicated with the number 6, it is superimposed on the flap 5 and has a detachable self-adhesive surface 8 and an edge 9.

The self-adhesive surface 8 has adhered to her detachably a paper tab 10 that has approximately disk shape, structurally independent and arranged in correspondence with the edge 9 of the label 6 of way that includes a part of this edge 9.

The tongue 10 protrudes from the edge 9.

Therefore, in order to open package 1 of reusable closure, just grab the tag self-adhesive 6 by tongue 10 and pull, peeling off label 6 of the flap 5 on the closing side 4 which is free so that open.

To close package 1, you only need reapply the label 6, still holding it by the tab 10.

Proper handling of the tongue 10 makes It is possible to open the package 1 by only partially detaching the label 6, so that only the adhesive of the self-adhesive surface 8 that adheres directly to the wrap 3 of paper and not over flap 5, with the result of that, when the adhesive loses its effectiveness, it only takes peel off tab 10 from tag 6 to discover an area of Self-adhesive surface 8 with fully effective adhesive. From way, it is possible to re-close package 1 using this new zone, thus extending the life of the self-adhesive label 6 of the invention.

The self-adhesive label 6 thus conceived, provides important advantages not only with respect to its use in reusable closure packaging, but also in relation to its mass production.

Currently, labels are produced in a line on a support band, usually of paper satin and impregnated with silicone, commonly known as paper crystal, which has special non-stick properties and resistance and on which the adhesive is initially spread, this adhesive being subsequently transferred to surface 8 self-adhesive labels 6. The adhesive is deposited on the support band in one or more longitudinal bands, letting the adhesive-free strips constitute the grip parts known.

The self-adhesive label 6 of the invention, which they do not have areas without adhesive on their self-adhesive surface 8, no requires separate strips of adhesive to be deposited along this band, but simply that the adhesive is arranged so uniform throughout the band, which is easier and cheaper.

In addition, the formation of the tongue 10 is also particularly simple, as will be evident from the description of a method for label production self-adhesive 6 according to the invention, offered below with reference to figures 3 and 4.

In figure 3, a number 11 is indicated rolled sheet of labels 6. This includes a band 15 of support, of the aforementioned crystal paper material, with a surface 12 on which labels 6 are applied in sequence forming a single line and opposite surface 13.

Referring on the other hand to figure 4, A roll of the rolled sheet 11 'is indicated with the number 14 still unprocessed, for the production of labels 6, which is consisting of a top sheet 16 of label paper, glued to the surface 12 of the support band 15.

In the first cutting station 17, the edges 9 of the labels 6 are cut on the upper sheet 16 and, subsequently, in a second cutting station 18, the edges 20 defining the tabs 10, making the cut from the opposite surface 13 of the support band 15.

At this point, the excess of the leaf is removed upper 16, delivering the rolled sheet 11 of Figure 3 with self-adhesive labels 6 and their tabs 10, ready to wind for subsequent application to packages 1 with closure reusable

The tab 10 is therefore directly formed on the support strip 15 of the crystal paper and its Resistance is therefore excellent.

In a preferred embodiment, the sheet top 16 unprocessed 15 band label paper for The production of labels 6, is also made of glass paper, that is, it is the type of paper generally used for sheets  rolled up that support labels.

Thanks to the resistance of the glass paper to tear, it is possible to use an adhesive in aqueous solution, which It is generally very strong, rather than an adhesive based on solvent that could have a detrimental effect on the products power supply contained in packages 1 with closure reusable

It is clear that an expert in this field would be able of making numerous variations in the structure of the label of according to the invention for packaging with reusable closure, in order to satisfy particular contingencies, without departing of the scope of the invention, as defined in the following claims.
