Description

FIELD OF TECHNOLOGY

The invention relates to a method for marking products, in particular, to a method for fixing a label in the form of a polymer strip with various identification information, fixed on the tongue of metal or plastic cans.

BACKGROUND OF THE INVENTION

A known method of labeling products, disclosed in US 4671836 A, publ. 06/09/1987. The method of product labeling includes applying a label to the product using hot melt adhesives.

The disadvantage of the technical solution disclosed above is the low positioning accuracy of the label relative to the center of the product.

In addition, the prior art method of labeling products, disclosed in RU 2461074 C2, publ. 09/10/2012. A method for labeling products by means of in-mould labels, wherein a film (polyethylene) for in-mould labels is placed in a mold for manufacturing a product made of plastic having an inner and outer surface, the film is positioned and the film adheres to the inner forming surface of the mold by ensuring that the second surface of the main layer of the film comes into contact with the inner forming surface of the mold, a labeled plastic product is formed in the mold at a temperature high enough to bond the hot-melt layer of the film to the outer surface of the plastic product, then the product is cooled and removed from the mold

The disadvantage of the technical solution disclosed above is the difficulty of applying the label to the product.

DISCLOSURE OF THE INVENTION

The objective of the claimed invention is to develop a method for attaching a label to the lid of metal or plastic cans with a tongue.

The technical result of the invention is to improve the positioning accuracy of the label relative to the tongue of metal or plastic cans.

The specified technical result is achieved due to the fact that the method of fixing the label in the form of a polymer sheet with different identification information on the lid of metal or plastic cans with a tongue for opening said can includes the following steps:

a) bringing the edge of the first part of the polymer sheet under the specified tongue;

b) interconnecting at the opening of said tongue the inner surface of the first part of the polymer sheet located under the said tongue of the said jar and the inner surface of the second part of the polymer sheet located above the said tongue, while the second part of the polymer sheet containing identification information on the outer surface , completely closes the specified tab and grooves to form an opening when opening the can.

Polyvinyl chloride (PVC), low density polyethylene (LDPE), oriented polystyrene (OPS), linear low density polyethylene (LLDPE), polyethylene terephthalate (PET), polyethylene (PE), biaxially oriented polypropylene film (BOP) are used as the polymer material for the label. ).

The inner surfaces of the first and second parts are connected by soldering, glue.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be better understood from the description, which is not restrictive and given with reference to the accompanying drawings, which show:

Fig. 1 - metal or plastic jar with a label made of a polymer sheet,

Fig. 2 - metal or plastic jar with a label made of a polymer sheet (enlarged side view).

1 - polymer sheet; 2 - junction; 3 - place of application of identification information; 4 - maximum border of the label; 5 - place of inflection; 6 - inner surface of the polymer sheet; 7 - outer surface of the polymer sheet; 8 - tongue.

IMPLEMENTATION OF THE INVENTION

To fix the label in the form of a polymer sheet made of polyethylene on the lid of the jars having a tongue for opening said jar, proceed as follows.

On the first one, the edge of the first part of the polymer sheet is brought under the specified tongue (8) with the formation of a place (5) of an inflection at the end of the tongue (8).

Then, a connection is made by soldering or glue to each other at the junction (2) (in the hole of the specified tongue (8)) of the inner surface (6) of the first part of the polymer sheet located under the specified tongue (8) of the specified jar, and the inner surface (6 ) the second part of the polymer sheet, located above the specified tongue, while the second part of the polymer sheet, containing identification information on the outer surface (7), completely covers the specified tongue (8) and grooves to form an opening when opening the can. Soldering is carried out as follows: local heating is carried out at the junction (2) of the inner surfaces (6) of the indicated two parts of the polymer sheet to a temperature at which the polymer is in a highly elastic state, the inner surfaces (6) of the indicated two parts of the polymer sheet are pressed, followed by cooling, leading to the connection of the internal surfaces (6) of these two parts of the polymer sheet due to the solidification of the polymer material at the place of heating.

At the same time, the connection at the junction (2) of the indicated internal surfaces (6) of the polymer sheet is carried out using glue, by applying the adhesive composition to the internal surfaces (6) of the indicated two parts of the polymer sheet, followed by pressing until the adhesive composition hardens, which leads to the connection inner surfaces (6) of said two parts of the polymer sheet at the place where the adhesive is applied.

The connection at the junction (2) of the indicated internal surfaces (6) of the polymer sheet is carried out at least at one point, having any shape (rectangle, square, circle, etc.) and a size not exceeding the size of the opening of the tongue (8).

The polymer sheet has any shape that does not go beyond the maximum border (4) of the label: rectangle, square, circle, etc.

The following information is contained on the outer surface (7) of the polymer sheet in the place (3) for applying identification information: name, composition of the product, volume/weight, rules for the use and storage of the product, manufacturer, expiration date, information about the advantage of the product, advertising, promotions, instant lotteries, etc.

The material of metal cans is aluminum (intended for storing drinks) or tin (intended for storing canned food). The material of plastic cans is PVC, LDPE, OPS, LLDPE, PET, PE, BOP. The plastic jar is made in the form of a body made of polymeric material and an aluminum lid with a tongue. A plastic jar is used, for example, for packaging toys.

The claimed method makes it possible to improve the accuracy of label positioning relative to the tongue of metal or plastic cans due to the initial positioning of the label on the tongue and subsequent secure fastening of the label by the claimed method on the tongue of the can, excluding the label from moving relative to the tongue or can. In addition, the claimed solution makes it possible to obtain a new and convenient place for the consumer and the manufacturer to place various information, including marketing information. In particular, the label, fixed in the claimed manner, will make it possible to place linear and two-dimensional codes on the product in an additional place to facilitate the passage of production and warehouse logistics processes. The label, fixed by the claimed method, also does not require the selection in its composition, the components for which certification is required for use in food production. The product itself, equipped with a label fixed in the claimed way, will not undergo physical changes in its current state (for example, when a self-adhesive label is applied to the product after its removal, glue may remain), nothing remains on the product after the label is removed. The label, fixed by the claimed method, can be applied once to the product, after its removal from this product, re-application is impossible. Also, when finding a label fixed in the language of the jar, there is a convenient opportunity to open the product itself (the jar), the label does not interfere with this opening.

The invention has been described above with reference to a specific embodiment. For specialists, other embodiments of the invention may be obvious, without changing its essence, as it is disclosed in the present description. Accordingly, the invention is to be considered limited in scope by the following claims only.
