The invention relates to the packaging case which is made by connecting a number of rigid or semi-rigid elements. More precisely the invention relates to collapsible containers with hinged connected items, which can be used mainly for transportation, storage and sale of vegetables.

Well-known wooden containers for fruit and vegetables (HOST-84)containing a bottom, side and end walls, made of pallet boards. The means of attachment known containers are nails or metal brackets. Box sets, typically manufactured from softwood its procurement, and Assembly - seasonal agricultural enterprises without the use of mechanization. Known container has sufficient rigidity and strength, is well ventilated and allows to transport fruit and vegetables in stacked form. However, the high consumption of materials and the complexity of Assembly of the container leads to its gradual displacement of the market of fruit and vegetable packaging. Used for the same purpose corrugated cardboard and plastic horticultural containers allows to mechanize the process of its production and transport to the consumer empties in factored form. The disadvantages of plastic and cardboard fruit and vegetable packaging should include PR is continued to be just, the high cost of raw materials, lower than that of wooden packaging, consumer properties and the additional costs of recycling associated with their harmful impact on the environment.

Efforts to eliminate these disadvantages have led to the creation of alternative designs of fruit and vegetable containers with a flexible basis. In particular, in French patent FR 2779089, CL B65D 6/14, 1999) presents a two-layer containers, containing made "under the tree" flexible framework and pasted it hard layer. Tara in the unfolded form is a flat panel, separated by zones of inflection on the bottom and side walls. Known containers allows to transport empty containers in factored form and reduce the cost of its production. However, the application of solid hard layer does not provide ravnopravnosti design that leads to the weighting of the container, and applying a flexible base made of polymer material requires additional costs for the disposal of packagings.

Known collapsible containers, which can be taken as a prototype (US 6844050, CL VV 3/00, 2005). Tara in the unfolded form is a three-layer flat panel, separated by V-shaped grooves or zones of inflection on the bottom and side walls. The preform consists of a flexible base and the two are glued to both sides of the flexible base SL is the pits. The flexible base may be made of mesh, lattice or filaments, and at least one outer layer of wood veneer, fiberboard or other similar materials. Known collapsible containers can be used for transportation and storage of fruits and vegetables. It is lighter than traditional wooden fruit and vegetable packaging and more environmentally friendly than plastic containers. However, the bottom and sides of the known packaging throughout its square have the same thickness, which does not allow efficient use of material. Because only parts of the bottom and side walls, adjacent to the zones of inflection, affect the rigidity of the container, and the middle of the bottom and side walls just keeps Packed in packaging the product. The material of these sections work in tension and may be considerably thinner than the perimeter of the bottom and side walls. In addition, technology for the production of packaging includes the hot pressing operation, which requires significant energy and labor costs. According to the invention in the case of applications for the hard layers of packaging wood veneer is applied in the form of sheets, as, for example, in the form of a short narrow strips. Short narrow strips of veneer can automatically discard and use glue. And large sheets of veneer pick up, rejected, and put glue on them manually or with the use of simple is mechanization. This significantly increases the cost of the manufacturing process of the container.

Thus, the present invention is to create ravnopolochny folding wooden containers, which with sufficient mechanical strength would be low intensity.

Another object of the invention is the creation of a design foldable containers, consisting of homogeneous wood elements suitable for automatic Assembly of the container.

Another objective of the present invention is the creation of environmentally friendly packaging that does not require much labour at its disposal.

Tasks are accomplished by that in a collapsible container formed from a flat blank, separated by zones of inflection at the bottom and at least four collapsible side walls containing a flexible basis, attached to the stiffening elements and means fixing the container in the assembled position, according to the invention, the stiffening elements are wood slats attached around the perimeter of the bottom and side walls. Moreover, in the preferred embodiment, the packaging flexible base made of the following materials: mesh, wood lattice, Kraft paper, or from their combination. These wood slats are of the same width, attached on both sides of the flexible base opposite to each other with glue. Located n the both sides of the flexible base angle of the pair of slats of the bottom and side walls attached to a flexible basis with ligation of the corner joints. Wood slats have a rectangular cross-sectional shape, and the thickness is in the range from 0.6 to 6 mm, preferably from 1 to 4 mm Zone of juncture between the bottom and side walls have a width equal to or greater than the thickness of the lamellae. Means fixing the container in assembled position in the preferred embodiment, its implementation are four plastic corner of the castle, each of which is provided with locking tabs with bevels. Adjacent to the corners of the sections of the side walls thus provided with fixing holes with the possibility of joining them in the locking tabs lock. And corner locks when connecting the corners of the container are able to fix the protective net covering the top of the filled container and prevent unauthorized access to the packaged product. Other features of the invention described in the claims and are explained in the description of the preferred implementation of the packaging.

Hereinafter the invention is explained by examples of implementation of the packaging according to the invention with reference to the accompanying drawings, which depict:
