Description

CONTAINER

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

The most well-known types of packaging, where the claimed utility model can be applied, are containers, the base of which is a container with a rectangular base, expanding towards its upper part, the main shaping/frame element of which is a predominantly flat pulp and paper material having a protective water-fat-repellent coating in the form of lamination, special impregnation or varnish. Moreover, such a container should not have rounded corners, but corners obtained by conjugation of two side planes of the vertical wall. The container is closed with a transparent lid; a lid containing a viewing window or a blind lid that does not have a window. In this case, the cover can be made both from a material similar to the base, and from a polymeric 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 the upper flange, which does not have a break along the container perimeter and is located at an angle to the horizontal plane, which creates a locking part around the entire perimeter of the container.

Prior Art: Known patent RU 190177 Ul, characterized in that the turn-off valves are not fastened together 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 together 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 conjugation of the side rectilinear planes of the vertical wall, in the known prior art, is, as a rule, the need to manually turn the valves before the possibility of such fastening of the lid. In addition, each outward-turning valve is independent, not fastened together, which makes it possible to have excessive mobility of individual valves on each side of the container independently of each other, which is unnecessary for the operation and use of the container, which reduces the rigidity of the structure, reduces ease of operation and closing speed, which is a significant limiting factor in the mass use of the container. In addition, in the absence of initially correctly provided fixing of the retractable valves in the position necessary for docking the lid, there is always a risk of incorrect or inaccurate docking of the lid to the container by an inexperienced consumer, both during the initial closing of the container and during possible re-closing. And the lack of fastening of the turn-off valves among themselves significantly reduces the rigidity of the container, especially in the position with the lid removed. This 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 the fastening of the unscrewed upper valves of the container to each other in the corner mating parts, fixing the correct position of the flange, which does not have a break in the corner parts of the container, with the correct, corresponding to the operating conditions of the lid, a preset angle of inclination from 20 to 90 degrees to the horizontal plane around the entire perimeter of the container immediately during its manufacture.

The technical result consists in a significant improvement of the prior art application of packaging made of pulp and paper material with a separately joined lid.

The technical result is expressed in the following advantages:

- Due to the fixed rigid flange initially formed during the manufacture of the container at an angle to the horizontal plane, which does not have breaks around 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, as during the initial closing, and when repeated, which is expressed in the economic effect, expressed in the reduction of assembly time and ease of use.

- Due to the formation of a rigid flange fastened in the corner mating parts of the outward-turning elements of the side walls - the upper valves, the structural rigidity of the container, which allows the use of thinner materials in the 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 to manually bend the valves during assembly and set 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 the absence of the need to have knowledge of the principles of closing such containers by an 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 turned outward - the upper valves, significantly increases the operational characteristics, the reliability of the container and _the tightness of the lid, which has a positive effect on the transportation and storage of food products.

Description of the manufacturing method.

The container base manufacturing process consists of several stages.

In the first stage, the pulp and paper material can be printed and embossed to obtain the desired decoration of the formed container and apply various designations. 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.

The second stage is the cutting of the workpiece. Also, at the same time as cutting with a die-cutting die, the necessary scoring channels are formed, and perforation lines and scoring channels can also be formed.

At the third stage, the base of the container is formed. Lateral triangular flaps are formed, fastened by thermal soldering or with the help of an adhesive composition. The upper valves are bent, which are fastened together in the corner parts of the container base, forming a continuous along the perimeter and fixed at an angle to the horizontal plane, the upper flange of the container.

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 that, when cutting out, to form a cut of the internal partition. Subsequently, at the stage of forming the base of the container, the internal partition is formed, as a rule, by the method of thermal soldering due to the special shape of the punch and the matrix with the provided shape of the partition.

It should be noted that the top flaps that form a continuous flange when interconnected should be designed to extend to the side. the mating upper valve of the adjacent side face relative to the size of the faces on which they are located. This is done in order to be able to reliably fasten the upper valves overlapping each other due to thermal soldering or using an adhesive composition. With this bonding method, the resulting top flange has a single layer of forming material over the longer side of the container and a double layer at the bonding and overlapping of adjacent top flaps forming this continuous flange.

It should be noted that for greater reliability of fastening and making the flange even more rigid, the number of layers of the forming material can be more than one or two, while providing an additional turn of the upper flap when forming a continuous flange.

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

Regardless of the previous stages, the manufacture of the container lid takes place. The lid can be made in various ways.

The main ways to make a cover can be:

- In the case of manufacturing a measuring cap, the thermal vacuum forming method or the injection molding method can be used.

- In the case of the manufacture of the cover from pulp and paper material, as in the case of the manufacture of the base, the method of die-cutting can be used and further assembly using an adhesive composition or a thermal method molding. In this case, protective coatings can be applied to the pulp and paper material of the lid, as well as to the material of the base of the container, to give the product the necessary grease-proof and hydrophobic properties.

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 with 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 production , 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 predetermined position is carried out during the production of the container, the lid is docked 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 its corner parts, fixed in one preset position, giving additional rigidity to the entire structure due to angular fastening at an angle to the horizontal plane, the upper flange of the tank allows you to open and re-close the lid repeatedly.

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, by fastening the upper valves of the container turned outwards to each other in the corner mating parts, fixing the correct position of the flange, so that the flange does not have a gap throughout the entire perimeter, and is formed with a predetermined angle of inclination to the horizontal plane along the entire perimeter of the container immediately during its production, which, in addition to ease of use, increases the speed of both initial closing and subsequent re-closing, significantly increases the rigidity of the entire structure, especially in the position with the cover removed. The resulting positive technical, mechanical and operational characteristics significantly affect the economic performance of the 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 from a composition based on biodegradable polymeric materials.

The proposed utility model is illustrated by drawings, where:

1 - container base or container;

2 - cover;

3 - top flange;

4 - corner parts of the flange;

5 - triangular valves;

6 - top valves;

7 - internal partition. On FIG. 1 shows a general view of a container having a rectangular base, expanding towards the upper part, without a docked lid, with an upper flange 3 formed immediately during manufacture, not having breaks in its corner parts 4, having an angle to the horizontal plane preset immediately during its manufacture and not having the possibility of changing it due to the lack of mobility due to overlapping of individual upper valves 6 with each other.

Side triangular valves are also shown, which are attached during the production of the container base to the inner cavity of the container from the side of the short side faces.

On FIG. 2 shows sections of the side walls of the container in the middle of the side wall and on the corner of the container. The essence of the utility model is shown, which consists in the angle T of inclination of the upper flange relative to the horizontal plane, predetermined during the manufacture of the base of the container, lying in the range from 20 to 90 degrees, in a single value along the entire perimeter of the flange, and fastening the flange in its corner parts by overlapping and fastening individual top valves.

Thus, immediately during the manufacture of the container base, a rigid upper flange without breaks along the entire perimeter of the container is obtained with a predetermined angle of inclination to the horizontal plane, which does not have the mobility of individual upper valves unnecessary for efficient and quick fastening of the cover.

On FIG. Figure 3 shows two versions of a transparent flat lid that can be joined with a container and locks located in the lower part of the lid and located so that when the lid is tightly closed, they are fixed under the container flange. The lid is made of a transparent polymer material and joins with the container without the need to bend the top valves or check their position before installing it, since the top valves are initially fastened together during the manufacture of the container, forming an upper flange with a predetermined angle to the horizontal plane, corresponding to the geometry of the lower part covers.

On FIG. 4 also shows two versions of a transparent high lid, which is joined to the container and locks located in the lower part of the lid and positioned so that when the lid is tightly closed, they are fixed under the container flange. The lid is made of a transparent polymeric material and snaps without the need to bend the upper valves of the container or check their position before installing it, since the upper valves are initially fastened to each other during the manufacture of the container base, forming an upper flange with a predetermined angle to the horizontal plane corresponding to the geometry of the lower part covers.

On FIG. Figure 5 shows variants of the geometry of the elements of the upper flaps of the container base to provide overlap and fasten them together at an angle to the horizontal plane to form a continuous upper flange, also formed at an angle to the horizontal plane, lying in the range from 20 to 90 degrees. On FIG. 6 shows a version of the container with an internal baffle 7. The presence of the baffle does not affect the design and operation of the lid, so it is not shown in FIG. 6 for clarity of the execution of the partition.

The groove provided at the bottom of the container, corresponding to the geometry of the inner partition of the container, is necessary for the convenience of transporting the bottom parts of the container, when placing them in packs one to one.

The partition can be provided at different heights, with changes in the geometry of the shape and attachment points, placed in different parts of the container and made more than one.

On FIG. 7 shows an example of a workpiece for assembling, connecting and fastening the flange elements to each other in the case of manufacturing the inner partition of the container.

On FIG. 8 also shows an example of the workpiece in its corner part to ensure the assembly and fastening of the top flaps to each other in the corner parts of the container at an angle to the horizontal surface.

It should be noted that this utility model, which is disclosed with a description of the specific attached drawings, is not limited to these embodiments described and shown by way of example only, and that changes and modifications that are obvious to a person skilled in the art are possible without going beyond the scope of the utility model. as it is disclosed in the attached formula.
