Description

The utility model relates to the field of manufacturing packaging for predominantly food products and products containing or excreted fats and moisture.

The most well-known types of packaging, where the claimed utility model can be used, are a container, the base of which is a container with a rectangular base expanding towards its upper part, the main shaping / frame element of which is predominantly flat pulp and paper material having a protective water-grease-repellent coating in the form of lamination, special impregnation or varnish. Moreover, such a container should not have rounded corners, but angles obtained by conjugation of two lateral planes of the vertical wall. The container is closed with a transparent lid; a cover containing a viewing window or a blind cover without a window. In this case, the cover can be made both of a material similar to the base, and of a polymer material.

The lid is attached to the upper part of the container by turning the upper valves outward and fastening them together in the corner parts of the container, forming an upper flange that does not have a gap around the container perimeter and is located at an angle to the horizontal plane, which creates a locking part along the entire perimeter of the container.

Prior art:

Known patent RU 190177 U1, characterized in that the unscrewed valves are not fastened to each other in the mating corner parts of the container.

Known European patent 001186456 (ISG / HRD / 50528ED), also characterized in that the turn-off valves are not fastened to each other in the mating corner parts of the container.

The main problem of fastening the lid by turning the valves outward on a rectangular container having not rounded corners, but angles obtained by conjugating the lateral rectilinear planes of the vertical wall, in the prior art is, as a rule, the need for manual opening of the valves before the possibility of such fastening of the lid. In addition, each outward-turning valve is independent, not fastened to each other, which makes it possible to have excessive mobility of individual valves on each side of the container, unnecessary for the functioning and use of the container, independently of each other, which reduces the rigidity of the structure, reduces the ease of operation and the closing speed, which is a significant limiting factor in the mass use of the container. In addition, in the absence of the initially correctly foreseen fixation of the unscrewed valves in the position necessary for docking the lid, there is always a risk of incorrect or inaccurate joining of the lid to the container by an inexperienced consumer, both during the initial closing of the container and in the event of a possible re-closing. And the lack of fastening of the turn-off valves to each other significantly reduces the rigidity of the container, especially in the position with the lid removed.

The present utility model solves the main problem of ease of use of the container when using the lid, eliminating the above disadvantages, due to the initial formation of the upper flange and fastening the unscrewed upper valves of the container to each other in the corner mating parts, fixing the correct position of the flange that does not have a gap in the corner parts of the correct, corresponding to the conditions of the functioning of the lid, a preset angle of inclination from 20 to 90 degrees to the horizontal plane along the entire perimeter of the container immediately during its manufacture.

The technical result consists in a significant improvement of the known prior art for the use of packaging made of cellulose and paper material with a separately butted lid.

The technical result is expressed in the following advantages:

due to the initially formed during the manufacture of the container, a fastened rigid flange at an angle to the horizontal plane, which does not have breaks along the entire perimeter of the container, and the exclusion of the mobility of individual upper valves on each of its sides, the time for assembling the container and docking the lid is significantly reduced, both during the initial closing and and when repeated, which is expressed in an economic effect, expressed in a reduction in assembly time and ease of use;

due to the formation of a rigid flange fastened in the corner mating parts of the side wall elements - the top flaps - turned outwardly, the structural rigidity of the container is significantly increased, which makes it possible to use thinner materials during manufacture. This advantage is expressed in the economic effect, expressed in the cost of the materials used both for the manufacture of the bottom part of the container - the container, and the lid;

no need for manual bending of the valves when assembling and setting the required angle of inclination to the horizontal plane or tracking the correct position of the upper valves when re-closing, due to their independent mobility on containers compared in the prior art, as well as no need to have knowledge of the principles of closing such containers inexperienced consumer, creates a separate advantage and ease of use;

The increased rigidity of the container due to the rigid flange initially formed during the manufacture of the container, fastened in the corner mating parts of the side wall elements that are turned outward - the upper valves, significantly increases the operational characteristics, the reliability of the container and the tightness of the lid abutment, which has a positive effect on the transportation and storage of food products.

Description of the manufacturing method

The manufacturing process of the container base consists of several stages.

In the first stage, printing and embossing can be applied to the pulp and paper material in order to obtain the necessary decoration for the formed container and apply various symbols. A protective coating is also applied to the pulp and paper material to impart the necessary grease-protective and hydrophobic properties to the surface of the material. The protective layer can be applied both before and after printing and embossing.

In the second stage, the blank is nibbled. Also, simultaneously with nibbling, the necessary creasing channels are formed, perforation lines and grooving channels can also be formed.

The third stage is the formation of the base of the container. Lateral triangular flaps are formed, held together by thermal soldering or using an adhesive. The upper valves are bent, which are fastened to each other in the corner parts of the container base, forming an upper flange of the container that is continuous along the perimeter and fixed at an angle to the horizontal plane.

Also, for the purpose of dividing the internal volume of the container into sections, when designing, it is necessary to design the cut of the workpiece so as to form the cut of the inner partition when cutting. In the future, at the stage of forming the base of the container, the inner partition is formed, as a rule, by the thermal soldering method due to the special shape of the punch and matrix with the provided shape of the partition.

It should be noted that top flanges that form a continuous flange when mutually bonded to each other must be designed to have an extension towards the mating top flap of an adjacent side face relative to the size of those faces on which they are located. This is done in order to be able to reliably overlap the upper valves with each other by thermal soldering or using an adhesive. In this bonding method, the resulting top flange has one layer of forming material over a greater length of the side of the container and a double layer at the bonding and overlap of adjacent top flaps forming this continuous flange.

It should be noted that for greater reliability of fastening and imparting even greater rigidity to the flange, the number of layers of the forming material can be more than one or two, while providing additional turning of the upper valve when forming a continuous flange.

It should be noted that the side triangular flaps can be attached both from the inside of the container and from the outside.

Independently of the previous steps, the container lid is manufactured. The cover can be made in a variety of ways.

The main methods for making the lid can be

in the case of manufacturing a polymer cover, a thermal vacuum molding method or an injection molding method can be used;

in the case of a lid made of pulp and paper material, a die-cutting method can be used, as in the case of a base, and further assembly using an adhesive or thermoforming. In this case, protective coatings can be applied to the cellulose-paper material of the lid, as well as to the material of the base of the container, to impart the necessary grease-protective and hydrophobic properties to the product.

In the future, during the operation of the container and the lid, the lid, which has locks for fixing on the upper flange of the container, easily joins the container on the upper flange, which was initially rigidly fixed during the manufacture of the container, fastened in the corner mating parts, having a fixed angle of inclination to the horizontal plane preset during manufacture , comparable to the angle of inclination of the lower docking part of the cover. At the same time, taking into account that the formation of the upper flange and its rigid fixation in a strictly specified position is carried out during the production of the container, the lid docking is carried out without preparatory operations on the container, does not require checking the correct position of the upper valves of the container and can be performed by an unprepared inexperienced consumer. It should be noted that without unnecessary mobility of individual valves, glued in their corner parts, fixed in one preset position, giving additional rigidity to the entire structure due to corner fastening at an angle to the horizontal plane, the top flange of the container allows you to open and re-close the lid many times.

Thus, the technical result is achieved due to the initial formation of the upper flange of the container at an angle to the horizontal plane, due to the fastening of the upper valves of the container that are turned outward to each other in the corner mating parts, fixing the correct position of the flange, so that the flange does not have a break throughout the entire perimeter, and is formed with a preset angle of inclination to the horizontal plane along the entire perimeter of the container immediately during its production, which, in addition to ease of operation, increasing the speed of both initial closing and subsequent re-closing, significantly increases the rigidity of the entire structure, especially in the position with the lid removed. The obtained positive technical, mechanical and operational characteristics significantly affect the economic indicators of application during mass operation in the circulation of food products, by reducing the assembly time of the container, as well as ease of use, both for manufacturers and distributors of food products, and for the end consumer.

An additional feature is that the protective layer can be made of a composition based on biodegradable polymeric materials.
