Description

The utility model relates to a reusable container in the form of a stackable box made of environmentally friendly natural wood material. The box is designed for transportation and storage of a wide range of food products, such as vegetables, fruits, bakery products, meat, fish, poultry, etc.

A collapsible box is known, consisting of two solid end panels with slotted handles, a bottom bottom panel made of longitudinal strips and two transverse connecting elements, and two side panels, each of which is also made of longitudinal strips and two transverse connecting elements. The two side panels overlap opposite side edges with their respective end panels to form a right-angled edge, and the bottom edges of the two side panels overlap the longitudinal edges of the bottom panel to form a right-angled edge (US 20160101896, CL B65B 11/02, published 14.04 .2016).

The disadvantages of this type of container include the rather laborious process of manufacturing the elements of the box, the selection of boards during assembly and their fastening using nails and staples, as well as a significant weight of the structure. When stacked, the boxes do not have the ability to be fixed with each other, which complicates the process of transporting goods in such boxes.

Known stackable box, made of eco-friendly wood fiber material and designed for storage and transportation of food products. The box contains a bottom and four side walls with elements for forming a rigid structure from them. The bottom along the perimeter is provided with bearing and supporting ledges, above which there are ventilation recesses corresponding to them and slot-like grooves of the side walls, with cut-handles formed in them. The upper edges of the side walls of one box are made with stepped protrusions to interact with another box when they are stacked (RU 2644326, class B65D 19/16, published on 02/08/2018).

The disadvantage of the known box is that its bottom is made solid, and the recesses formed on the side walls do not allow sufficient ventilation of the inside of the box, which can adversely affect the quality of the products stored in it, in particular such as vegetables and fruits. .

Known, selected as a prototype, a fruit box, consisting of walls, bottom and lid of the same design in the form of lattices of rod elements with support bars. These parts of the box are interconnected by means of rings made of soft but durable material, which ensures their flexible connection when disassembled. For rigid fixation of the assembled box parts, fixing screws are used (US 141389, published 07/29/1873).

The disadvantages of the prototype include the following: the unreliability of the design; the complexity of making connections; the lack of the possibility of fixed stacking, which complicates, in particular, the process of transporting boxes.

The technical problem solved by the utility model is to improve the operational properties of the box.

The technical result aimed at solving the named technical problem consists in providing the possibility of storage and transportation, incl. perishable food products, in boxes of the proposed design installed in a stack without losing the appearance of the goods and food products and losing their freshness.

In addition, the technical result of the utility model is to increase the strength and reliability of the design of the box as a whole, which will increase its carrying capacity.

The positive properties of the proposed utility model can also include the use of environmentally friendly and environmentally friendly after disposal of natural materials in the manufacture of a box that is harmless to human health.

The specified technical result is achieved in the utility model using the following set of features.

Just like in the prototype, the box body consists of a bottom and two pairs of opposite side walls. One pair of said side walls and the bottom are made of rod elements located at a distance from each other, the ends of which are fixed on the support bars.

Unlike the prototype, another pair of side walls is made of sheet elements with slotted handles connected to the ends of the support bars. Between the ends of the support beams and side walls made of sheet elements, on the side of the open part of the body, there are stacking bars with parts protruding beyond the edges of the side walls made of sheet elements, and the bottom is made recessed inside the body.

The distance from the lower edge of each wall of the sheet element to the bottom of the housing is greater than or equal to the height of the protruding part of the stacking bar.

Planks for stacking are made with recesses in the area of the slots-handles.

In the middle part of the bottom, along the side walls of the rod elements, there are additional support bars.

The bottom is provided with stiffening elements in the form of jumpers located in its lower part along the side walls made of sheet elements, while the ends of the jumpers are made in the form of hooks connected to the support bars of the side walls made of rod elements.

The body of the box is made of natural wood material.

The utility model is illustrated by drawings.

Figure 1 shows a box (a perspective view from above).

Figure 2 shows a box (a perspective view from below).

Figure 3 - sectional plane A in figure 1.

Figure 4 - boxes installed in a stack.

Shown in FIG. 1, 2 the box has a rectangular shape, an open part and is formed from the side walls and the bottom. Two opposite side walls of the box are made of rod elements 1, the ends of which are fixed on the support bars 2, each representing a single lattice element. The bottom of the box consists of two such lattice elements located in the same plane. The lattice structure of said side walls and bottom ensures good air exchange inside the box, which allows the food products contained in it to stay fresh longer.

The other two opposite side walls of the box are made of sheet elements 3 and are connected to the upper and lower support bars 2 of the walls of the rod elements 1 by means of fasteners 4, for example, in the form of self-tapping screws (Fig. 3). Slot-handles 5 are formed in the walls of sheet elements 3.

For the reliability of the design, the box is equipped with stiffening elements in the form of jumpers 6 made of sheet material with clamps in the form of hooks 7 at the ends, designed to be fixed on the lower support bars 2 of the walls of the rod elements 1. Making the bottom of the box with additional support bars 2 located along the side walls from rod elements 1, as well as stiffening elements in the form of jumpers 6, allows to reduce the load from the goods on the bottom of the box.

To enable stacking, planks 8 made of sheet material with protruding parts 9 are used, which are fixed in the upper part of the walls of sheet elements 3 between them and the upper support bars 2 on the inside of the box. For the same purpose, the bottom of the box is recessed into the body under the condition that the distance from the lower edge of each wall of the sheet element 3 is greater than or equal to the height of the protruding part 9 of the bar 8. The installation of boxes of the proposed design in a stack is carried out by fitting a recess from the side of the bottom of each box on the protruding part 9 of the strap 8 (Fig. 4), which ensures their reliable connection during transportation and storage.

For the convenience of gripping by hand during the transfer of each box in the middle part of the slats 8 in the area of the slots-handles 5 recesses are formed.

The drawer parts are made from affordable raw materials, which is natural wood material, by laser cutting on CNC machines and turning on circular stick machines. The speed of assembly of the box is ensured by the use of assembly devices in the form of assembly conductors.

The proposed box can be used in different climatic and temperature conditions.
