Description

The invention relates to a packaging container for transporting and storing vegetable and fruit products, with the possibility of stacking.

Known US Pat. RF №2.690.331, IPC F16B 5/07, "Joining parts made of sheet material of uneven thickness by the method of joining" thorn-groove ", publ. May 31, 2019 Bul. No. 16.

The invention is intended for the manufacture of prefabricated joinery from sheet material with uneven thickness.

It is possible to obtain a high-quality one-piece connection without fitting and using special fasteners.

The parts are connected by inserting the thorn of one part into the groove of the other, with their relative position perpendicular to each other. The length of the tenon is comparable to the depth of the groove or may exceed it. During assembly, the spikes pass through the grooves, which are made through. The product is manufactured using a laser and numerically controlled machine tools, which makes it possible to obtain tenons and grooves with high manufacturing accuracy. During assembly, a high-quality fixed connection is provided, without additional adjustment and machining.

Known multi-turn board boxes for storing and transporting vegetables and fruits, which are produced in accordance with GOST 17812-72. Moscow, Standardinform. 2008 r.

Boxes are produced non-collapsible, using boards made of soft hardwood or birch.

The boxes are assembled using nails, screws or wire staples.

End or side walls are made of planks, planks using nails. The extreme planks are attached in addition to the triangular planks with two nails - one at each end of the plank. The lower planks are nailed to the planks at a certain distance from the ends of the planks, one nail into each plank of the bottom.

Then the corners of the box and the planks of the end and side walls are fixed with corners made of steel packing tape. Planks for the end and side walls, bottom and triangular strips are presented in a set to the place of assembly of the boxes, in a set for each box. After assembly, the product boxes are transported by road.

The disadvantages of this type of container boxes include:

- laboriousness of the process of manufacturing and selection of component boards, their fastening using nails and staples, upholstered with steel tape. There is no reliable installation of boxes on top of each other, when fixing their position, which complicates the transportation process;

The reusability of containers, specifically boxes, implies their return to the consumer, for repeated and subsequent use during the transportation of products;

Since the planks have a small cross-section, when the box is filled with products, the latter can deform with expansion from the center;

- there is a limitation on the number of boxes in the stack, since the axial load on the lower boxes in the stack is perceived only by triangular strips, which is not enough;

- the load on the planks of the bottom of the box is perceived by nails with the transfer of this load to the metal strip, but the planks of the bottom may bend, which is undesirable.

It is known to manufacture and use polymeric reversible boxes produced in accordance with GOST 33746-2016.

The boxes consist of a bottom, with longitudinal and transverse sides connected to each other during manufacture.

The sidewalls are equipped with structural elements that allow you to grip by hand, or using lifting equipment. To ensure stacking, structural elements are provided in the form of curly spikes or grooves, which makes it possible to ensure the stability of the boxes in the stack.

The boxes are manufactured by pressing under pressure using a polymer material such as polyethylene.

The disadvantages of the design include:

- the load on the bottom from the product leads to its sagging, as well as to the deformation of the longitudinal sides, especially when the load from the higher boxes in the stack is perceived.

Known US Pat. RF №2.726.568, IPC B65D 5/04, "Folding box container", publ. 07/14/2020 Bul. No. 20, taken by the author as a prototype.

A folding box-container consists of a bottom, longitudinal and transverse sides, with grooves and spikes, for fixing boxes-containers when stacking. Cutouts are made in the body of the longitudinal sidewalls, and grooves are made in the transverse sidewalls. The bottom is equipped with figured notches, with fixing grooves, which are spaced along the perimeter of the bottom, with the formation of protrusions and through grooves at the corners and in the middle part. The longitudinal and transverse sidewalls are provided with spikes located at the same distance, equal to the distance between the through grooves on the bottom.

The protrusions on the end surfaces of the longitudinal sidewalls between the fixing notches and the longitudinal grooves in the lower part are made with the condition of interaction with the corresponding protrusions on the bottom ends.

The transverse sidewalls are provided with vertical grooves at the ends and longitudinal grooves in the lower part, which are made with the possibility of interacting with the corresponding projections on the ends of the bottom, the grooves on the transverse sidewalls are made at a distance equal to the distance between the projections on the ends of the longitudinal sidewalls. The longitudinal and transverse sidewalls at the ends are provided with figured cutouts, and the longitudinal sidewalls additionally have a figured cutout in the middle part to accommodate the spikes when stacked.

Assembly of boxes-containers.

The bottom is installed on a horizontal surface, with the installation of the first longitudinal sidewall. For this, the protrusions at the bottom end are introduced into the longitudinal grooves, with the contact of the body of the longitudinal sidewall with the body of the bottom, at the place where the figured cuts are made.

When moving the longitudinal sidewall to the right, it is inserted into the fixing grooves. The installation of the second longitudinal sidewall is carried out in a similar way. Then, transverse sidewalls are installed between the longitudinal sidewalls. To do this, protrusions on the body of the transverse sidewalls are introduced into the longitudinal grooves on the bottom body. At the same time, protrusions on the end surface of the longitudinal sidewalls are introduced into the vertical grooves on the transverse sidewall.

By moving the transverse sidewall relative to the projections, the body of the transverse sidewall is introduced into the fixing grooves.

By moving the transverse sidewall upwards, the protrusions at the ends of the longitudinal sidewalls are introduced into the corresponding grooves, with fixation inside the fixing grooves.

The second transverse sidewall is installed in the same way.

After assembly, the thorns on the body of the longitudinal and transverse sidewalls are directed upwards.

When stacking, the spikes of all sidewalls enter through grooves on the bottom of the box, with fixing their mutual position.

The disadvantages of the design include:

- the complexity of the structure of the bottom and the fixing element;

- with a sufficiently large weight of the load, the load is taken up by the bottom, with the transfer of the load to the protrusions, without support in the middle part of the bottom, which, with its small thickness, there is a possibility of sagging, which leads to uneven loading of the protrusions and fixing elements;

- installation and fixation of the transverse sidewalls is difficult due to the need to simultaneously install the protrusions on the lower grooves with the input to the fixing elements, with the vertical grooves pointing to the protrusions on the ends of the longitudinal sidewalls;

- there is a dead zone at the corners of the container-box, determined by the distance from the protrusions on the bottom to the corner, which leads to deformation of the bottom in this place.

The technical result that can be obtained by carrying out the proposed invention;

- the ability to quickly assemble a box-container, without the use of special tools;

- the possibility of stacking boxes, containers, with fixation, using spikes and recesses;

- installation of longitudinal sides at an angle to the bottom reduces the load on the bottom from the goods in the box-container;

- the installation in the middle of the container-box of a longitudinal lintel and its connection with the bottom and transverse sides enhances the strength and reliability of the structure as a whole;

- it is possible to fix the stacks to each other by supplying the mounting tape through the windows at high tides;

- increasing the rigidity of the structure by changing the fixing mechanism of the transverse sidewalls with the longitudinal sidewalls.

The technical result is achieved by the fact that the collecting box-container consists of longitudinal and transverse sidewalls, provided with through grooves and spikes, for fixing boxes-containers when stacking, a bottom with through grooves and fixing elements spaced around the perimeter, protrusions on the ends of the longitudinal sidewalls. The collecting box-container is equipped with a longitudinal partition located in the middle part, at the ends of which fixing elements are made, alternating with protrusions, for the corresponding through grooves on the body of the bottom and transverse sides, equipped with tides, with spikes in the upper part and notches made at an oblique angle to the bottom, the longitudinal sidewalls are equipped with mating grooves at the ends, with the possibility of interacting with the notches, covering the body of the transverse sidewalls, and the tides are equipped with windows and recesses for the corresponding spikes, and the fixing elements are made between two cuts and have an L-shape with an internal hook and external rounding.
