FR2719023A1 - Tray that can be engaged with adjacent trays when stacked - Google Patents

Abstract

The tray has a stagger formed in its perimeter at its median point. In the upper half of its side two location cut-out points are provided having a specific width. In the lower half, corresponding lugs or protrusions are provided which also have a specific width. In the area where the two trays engage (2), the trays are provided with an area formed from inclined planes. This acts to centre the upper tray as it is positioned above the lower tray. This feature allows the trays to be formed into piles or slid prior to being engaged one into the other.

Description

The invention relates to an improved stackable and built-in box.

  There are known stackable-built-in boxes of the parallelepiped type, straight, rectangular, with a staggering of the perimeter in their middle part and provided in the upper half of their sides with housings and in the lower half of said sides with projections / supports arranged s functionally between them (them) to allow the stacking, when full, of certain boxes on others and to allow, by performing a rotation of

  degrees, the embedding of some cases in others.

  Also known from utility model 225.242 by the same applicant is an improvement in this type of boxes which allows the top box to slide above the one below, so as to perform the stacking function and / or to carry out the embedding function, in which the two projections / supports of the lower half of each of the sides have a distinct width, the widest projection being located closest to one end of the side and the projection the narrower being located at a greater distance on the opposite side. 25 This arrangement allowing the stacking and / or the embedding of a box on the one below presents the risk that the projections penetrate into the bottom box of non-shaped desirable, particularly when for reasons of the dimensions of the contents, the design of the box must be made so that the projections / supports have a small thickness. In such a case, the risk of inadvertent penetration of the top box into the bottom box is high. The object of the invention is to overcome this drawback, that is to say to obtain a box which operates safely even when the projections / supports have a small thickness. To achieve this, a structure consisting essentially of inclined planes has been provided, located in the seating area of the projections / supports, which centers the upper body on the lower body when the first

  is pressed on the second to proceed with its stacking or sliding prior to stacking or embedding.10 In order to facilitate understanding of the invention, the following description is accompanied by 3

  drawing boards representing an exemplary embodiment cited by way of non-limiting example. In the drawing: Figure 1 shows a side view of the body. Figure 2 is a view of the same box, before it is superimposed on the box below, to proceed to its stacking or embedding by sliding. Figure 3 is a detail view of the box shown in Figure 2. Figure 4 is a view of the same box, once superimposed on the box below, to proceed to its stacking or embedding by sliding. Figure 5 is a detail view of the body shown

in Figure 4.

  Referring to the figures, there is shown a box (1) provided with projections / supports (2) in the seating area of which inclined planes (3; 4) have been provided which center the top box on that of the below when the first is pressed on the second (figure 2) to stack or slide the top box onto the bottom box

(figure 4).

  The substance of the invention can be practiced in other embodiments different in detail from that indicated by way of example

  in the description and to which also relates

  the protection claimed. It can therefore be produced in other forms and dimensions with the most appropriate materials in order to remain in the spirit of

claims.

Claims (1)

CLAIM8   1. Improved stackable-built-in box of the parallelepiped type, straight, rectangular, with a staggering of the perimeter in its middle part and provided in the upper half of the sides of the box with two housings of distinct width and in the lower half of the sides of projections / corresponding supports of distinct width, these housings and projections / supports being located at opposite ends of the sides, characterized in that a structure formed essentially by inclined planes has been provided in the seating area of the projections / supports (3, 4) which center the box (1) above on that below when the first is pressed on the second to stack it or   to its sliding prior to stacking or embedding.
