Description

Application area

The utility model refers to the packaging container, made in the form of a cardboard container with a plastic lid.

The utility model can be used in the food industry for food packaging.

Prior art

The increase in the range of goods (products), including food, which are offered by modern industry, contributes to the development of packaging business and the constant development, development and improvement of product packaging. The development of packaging is a very important and time-consuming business, since, on the one hand, packaging should cause the interest of the buyer to the product placed in it. On the other hand, packaging should be easily recognizable and have ease of manufacture, minimal material and labor costs, and on the third hand, it should perform the functions of packaging that preserve consumer properties of the product during its transportation, storage and use. In the manufacture of packaging using different materials. For example: a tree; fabrics; polyethylene; cardboard etc.

At this stage, widespread use of cardboard containers (boxes) with a plastic lid for food packaging. The concept of cardboard packaging (cardboard) includes containers made of paper, cardboard and other layered materials. The basis of the made sheet of cardboard is cellulose with various additives. A sheet of cardboard differs from a sheet of paper with a density of no more than 160 g / m ^{2 of} paper, and also the cardboard usually consists of several layers, and the paper is one layer. Packing cartons include all varieties that are suitable for the manufacture of containers (boxes) of them.

Cardboard consists of several layers: upper, inner and lower, the choice of the structure of the cardboard depends on the properties of the product, which will be located in the container.

The main grades of cardboard used for the manufacture of containers (boxes) include: uncoated; coated; cast coating; chromium ersatz; chrome board; duplex board; triplex cardboard, cellulose cardboard.

A method of manufacturing a cardboard container usually consists of three stages.

At the first stage, a stamp is applied to a sheet of cardboard in order to obtain the necessary inscriptions and decoration of the container being formed. Also on the sheet of cardboard can be stamped, stickers.

At the second stage, cutting of the contour blank from the cardboard sheet takes place. Also simultaneously with the cutting, stamp, the necessary bending lines of the end walls, inserts, and valves are penetrated or punched.

At the third stage, a container is formed, with sizing of the inserts.

Separately, the production of a plastic cover, which allows the inspection of internal contents without removing the cover. The cover can be made in various ways. For example: molded under vacuum.

The closest technical solution to the proposed utility model is a technical solution for patent No. RU102942 publ. 04/06/2017 for a utility model, which is a cardboard container made in the shape of an inverted truncated pyramid with a quadrangular rectangular base (bottom) adjacent to the end walls, to the upper part of which, along the fold line, the valves adjoin, and the inner wall with the skirt, which form a longitudinal groove into which the aforementioned bend of the end wall with the valve is inserted, with the protrusion in the skirt facing inward of the lid and interacting with the outer rim Omskom mentioned container valves, as well as in the skirt around its perimeter made a collar, facing outward cover.

A constructive feature of the known technical solution is that the valves at the edges of the container are narrow, and in the middle contain semicircular inserts that are designed to open the container (a person on both sides lifts the inserts and, accordingly, valves, and this contributes to detaching the outer edge of the valve from the skirt lugs, which leads to to remove the cover from the container), while the protrusions made in the middle part of the skirt closer to the upper part of the longitudinal groove and interact with the outer edge of the valves in their zoy part. In order to eliminate the possible inadvertent opening (opening) of the container (removing the lid from it) in the lower part of the skirt, a shoulder protruding outside the lid is made at its border. Since the presence of hemispherical inserts on the valves increases the impact and the likelihood of inadvertent opening of the container, as hemispherical inserts increase the lever of the valves, and accordingly the effects on the valves, and the end wall, and with a slight effect on the hemispherical inserts, which, in turn, increases the likelihood of inadvertent opening container. Therefore, in order to reduce the impact on the long longitudinal walls of the container, the upper part of the lid is placed below the upper part of the longitudinal groove. As a result, the contact area of the end wall with the lid wall in the longitudinal groove increases. This reduces the internal usable volume of the container, but does not reduce the likelihood of unintentional opening of the container, and also leads to the contact of the product with the top surface of the cover. With this implementation of the cover, when its upper surface is located below the upper part of the longitudinal groove, the inner contents of the container are not sealed from free ambient air.

The disadvantages of the known technical solution is:

high material consumption associated with the implementation of additional hemispherical inserts on the valves;

an increase in the outer dimensions of the lid due to the additional shoulder made in the lower part of the skirt along its border, which, in turn, reduces the area of the trade showcase of the refrigerating chamber, or the box in which the containers of the product’s refrigerating chamber are arranged in a stack. The presence of the collar reduces the interaction and the stable arrangement of containers in vertical and horizontal rows (stacks), which can lead to the overturning of containers, and also requires additional attention and care in laying and transporting them;

fixing the protrusions of the skirt with the outer edge of the valve of the container is carried out in the narrowest part of the valve (the width of the container in the narrow part is no more than 4 mm) increases the likelihood of valve rupture, reduces the number of removals and dressing of the cover on the container, and also limits the internal working volume of the container. Since in the case of transferring a container filled with product to the lid, there may be an unintended opening of the container caused by the weight of the product placed in the container. Especially when the container is placed in the refrigerating chamber, which leads to an increase in the moisture of the cardboard, which leads to a loss of its hardness and elasticity; due to the presence of protruding hemispherical inserts on the valves, a large lever arises and a stroke in the process of tearing off the container, which, if not carefully moved, moving, can lead to unauthorized (unintentional) opening of the container.

Also, the task of the utility model is to expand the arsenal of the constructive implementation of cardboard containers with a plastic lid.

Other objectives and advantages of the proposed utility model will be discussed below as the present description and figures are presented.

The essence of the utility model

So a well-known container with a plastic lid, in which the said container is made in the shape of an inverted truncated pyramid with a quadrangular rectangular base, to which the end walls are adjacent, to the upper part of which, along the fold line, the valves are adjacent, and the said cover contains the upper surface and the inner wall with a skirt which form a longitudinal groove into which the aforementioned bend of the end wall with the valve is inserted, while in the skirt there are protrusions facing the inside of the lid and interacting with the outside to The closure facing the outside of the lid is made in the container valves as well as in the skirt, along its entire perimeter. According to the proposed utility model, the width of the upper part of the longitudinal groove is smaller than the thickness of the bend of the end wall with the valve, while the said upper part of the longitudinal groove is made the collar, on which the end wall bend with the flap rests, and in the lower part of the skirt, along its entire perimeter, the limb is made facing the outside of the lid, while the said protrusions are located in the lower part of the skirt above the mentioned tgib.

As a result of using the proposed utility model, the upper part of the longitudinal groove essentially forms a stiffener along the length of the longitudinal groove and in the upper part of the skirt, and the bend made in the lower part of the skirt and facing the outside of the cover also performs the function of stiffness, and this, on the one hand, increases rigidity as a fold of valves on the end wall, and on the other hand, increases the rigidity of the skirt, which reduces the unintended opening of the container and improves the fixation of the cover on the container. On the third side, the execution of the upper part of the longitudinal groove is less than the thickness of the bend of the end wall with the valve and the location of the collar under it, made in the skirt and facing the outside of the lid, makes it possible to fix the lid on the container with tension and at the same time increase the pairing of the limb with the skirt, which improves fixing the projections outer edge of the valves. Since the container is made in the shape of an inverted truncated pyramid with a quadrangular rectangular base, with the result that the end walls are angled, therefore making the collar in the upper part of the skirt under the upper part of the longitudinal groove results in a better position in the fold line of the valve on the end wall the junction of the fold to the collar, which reduces the air exchange of the inner contents of the container with the ambient air, and also, in this case, the collar performs the function of a stiffener, which increases the stiffness s longitudinal groove along the folds of the flaps on the end wall, and allows you to position the tabs at the bottom of the skirt, which allows to increase the width of the valve, which increases their hardness, increases the amount of withdrawals and dressing lid from the container, which is also an advantage of the proposed utility model. The location of the protrusions in the lower part of the skirt near the limb, on the one hand, allows to increase the width of the valve, and, on the other hand, since the limb is essentially a stiffener, such an arrangement of the projections reduces the deformation of the lower part of the skirt and, accordingly, the free course of the projections, which increases the connection of the protrusion with the outer end surface of the valve (in other words, fixing the lid on the container) and, accordingly, reduces the likelihood of unintentionally opening the container, which is also another advantage om proposed utility model. The location of the collar under the upper part of the longitudinal groove reduces the outer dimensions of the cover and avoids the use of hemispherical inserts made on the valves, compared with the prior art, since increasing the width of the valve increases its rigidity and reduces the requirements for more careful opening, which is necessary with a small width valve. Therefore, the use of the proposed utility model can also reduce material costs, which is also an advantage of the utility model. It should also be added that the execution of a bend in the lower part of the skirt increases the area of interaction between the fingers and the skirt in the process of removing the lid from the container, which increases the rigidity of the lid, as well as simplifies the opening of the container, since the location of the projections above the bend ensures safe opening of the container, because for the bend it is easier to bend the skirt for opening the container, which increases the number of cycles of use of the proposed utility model, and this is also its advantage .

Also, according to a variant of the utility model, in which the angle α formed between the wall and the skirt in the longitudinal groove is 10-30 ^° , and the angle β formed between the lower surface and the surface of the skirt located in the longitudinal groove is 80-85 ^° .

This allows you to adjust the angle of opening of the longitudinal groove in a wide range, which avoids the need for a complete valve breakage on the end wall, and also simplifies putting the lid on the container and improves the hook with your fingers on the skirt during the opening process (removal) of the lid from the container, as well as reduces the load in the process of removing the cover from the container, which is also an advantage of the proposed utility model.

Also, according to a variant of the utility model, the lid is made transparent; this allows inspection of the internal contents (internal volume) of the container without removing the lid.

Also, according to a variant of the utility model, the limb is made wavy with the formation of teeth. This increases the length of the limb and its height, which leads to an increase in the rigidity of the lower part of the skirt and the lid as a whole, as well as to an increase in the gripping area of the limb with the fingers in the process of removing the lid from the container.

Examples of the implementation of the utility model

Example №1

FIG. 1-13 depict a first example of a utility model, according to which a blank is formed from a cardboard sheet, followed by the formation of a cardboard container 1. Joints 1 _{2 are} glued and fixed on the end walls 1 _1. As a result, a cardboard container 1 is formed. Manufactured containers 1 are collected in piles. Separately, for example, by casting under vacuum, make the cover 2. The covers 2, like the containers 1, are stacked and sent for use, for example, in the food shop, kitchen, dining room, in the place where the product is made (for example, salads, cuts, fruits and vegetables, salads and other food or culinary products (products), which will be placed in container 2. But first, the packer (packer) takes container 1 from one bundle and bends the valves 6 on the end wall 1 ₁ along the fold line 6 ₃ , while using the proposed oh packer useful model must not strongly gloss over valves 6, they only need to bend, as collar 4 using ₂ formed in the upper portion of the skirt 4, the longitudinal groove has a large opening angle and the twisting of the valve 6, and this reduces the time lapel valves 6 and eliminates the strong room of the valves 6 ₁ along the bend line 6 ₃ , and also saves time and simplifies assembly (putting the lid 2 on the container 1), which is also an advantage of the proposed utility model. After bending the valves 6 on the end surface 6 _{1, the} packer places product 1 into the internal cavity of the container and puts on cover 2, causing the outer edge 6 _{2 of} valve 6 to engage with projections 4 ₁ made in skirt 4 of cover 2. At the same time When putting the lid 2 on the container 1, the packer does not need to center much and watch how the lid 2 is attached to the container 1 (valve hall 6 on the end wall 1), since using the proposed utility model this process is more efficient. After that, the containers with the product are stacked in a box, display case, shelf in the dining room, etc.

Thanks to the implementation at the ends of the boards 2 ₂ segments 2 ₄ it is easier to remove them from the stack of containers, which are located in the box, the shelf of the display case, the counter, etc. since the presence of segments 2 ₄ , make empty space and the gap between the containers stacked on top of each other and increase the area to capture the container 2 from its base 1 ₃ while maintaining the stability of the superior containers. Also the presence of segments 2 ₄ in the zone of their junction to the bottom surface 2 ₃ makes expansion of the bottom surface along the ends of the cover 2. This expansion of the bottom surface 2 ₃ can be used to better open the cover 2 with reduced efforts, and which would reduce the deformation of the valves 6, in the process of removing the cover. So a person puts a thumb cushion on the bottom surface expansion 2 ₃ , and with the index or middle finger lifts the lid 2 through skirt 4, or another option is possible, when the person puts the index finger on the lower surface expansion 2 ₃ , with the thumb lifts the skirt 4. As a result the cover 2 is removed from the container 2 from the ends, which simplifies the removal of the cover and reduces the deformation of the valves 6 of the container 1, which is also an advantage of the proposed utility model. In this case, I would like to separately note that the use of the bead 4 ₂ , made in the upper part of the skirt 4, increases the opening angle of the longitudinal groove 7 and the use of the bend 4 ₃ , improves the effect on the skirt 4 in the process of removing the cover 2 from the container 1, and also allows to wear cover 2 on container 1 without damaging the structure of the cardboard along the bending line 6 ₁ , which is also an advantage of the utility model.

Example 2

FIG. 14-16, the second embodiment of the cover is made according to the utility model, which differs in that in the lower part of the skirt 4 the bend 4 _{3 is} made wavy with the formation of teeth 4 ₄ .

It is clear that the above are only a few possible options for the implementation of the proposed utility model. The utility model is not limited to the examples outlined above.

For example, the dimensions of the container may have the following values: A1, B1 -80-225 mm; A2, B2 - 90-225; C1 is 43-65 mm; H1 is 6-12 mm; The container is made of cardboard with a density of 232 - 342 g / m². The step t between the ribs is 30-50 mm. The width of the upper surface of the ribs h1 is 1-3 mm.

Also, according to a variant of the utility model, a water-repellent layer can be made on the inner surface of the container, for example, a laminated water-repellent layer, which allows the use of wet foods, for example, salads, cuts, juicy vegetables and fruits, etc.

For example, it is clear that when using the proposed utility model, the outer surface of the cardboard container can be made in various graphical designs.

It is also clear that perforation or trimming can be performed along the fold line.

Technical result

The technical result of the proposed utility model is to increase the rigidity of the container and the reliability of fixing the cover on it.
