FR2719022A1 - 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. The location cut-out points and lugs are arranged at opposite ends of the edges. One end lug (2) is positioned on the vertical corner contiguous to the smallest lug (3). The interior contiguous angles of the upper half of the tray are provided with vertical grooves that form the angle.

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 No. 225.242 by the same applicant is an improvement in this type of boxes which allows the top box to

  slide above that below, so as to carry out 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.

  This arrangement allowing the stacking and / or embedding of a box on that below implies that the projection / support of lesser width, and therefore the most fragile, is that being the most distant from the end of the side and so be the one with the greatest load. The object of the invention is to overcome these drawbacks, that is to say to obtain a box which at the same time allows stacking and / or embedding by sliding it over the one below, which allows also withstand high loads. To achieve this, an end projection / support has been provided which cooperates with the smallest projection to support the load of the body on the corresponding end or which is initially the most fragile. With the body, object of the present invention, in the operational phase of embedding in a vacuum and in that of stacking on solid by sliding, the projection / support of lesser width lifts the body during sliding by 5 the edge inclined from the bottom case, which allows the projection / end support to overcome the housing

  without hindering the fact of allowing in this way the embedding by sliding of a box in another or the stacking of a box on another. 10 In order to facilitate the understanding of the invention, the following description is accompanied by 4

  drawing boards representing an exemplary embodiment cited by way of non-limiting example. In the drawing: Figure 1 shows a top plan view of the body. Figure 2 is a side view of two boxes being slid to be stacked, when the projection / end support comes above the upper housing without hindrance. Figure 3 is a side view of two boxes in the process of sliding to be embedded, at the time when the projection / end support passed over the lower housing without hindrance. Figure 4 is a view of two boxes stacked in shape

stable.

  Referring to the figures, a box (1) is shown, the end projection / support (2) of which is located on the contiguous vertical edge of the smallest projection / support (3). In the mounting position, the projection / end support (2) is housed in the vertical groove

  (4) located in the interior corner of the upper half of the body.

  The end protrusion / support can be provided so that it can be incorporated into boxes when these are designed to contain heavy weights and so that they can be removed when the boxes are designed to contain light weights, all this is provided in an operational manner so that the first can be embedded with the second without damaging the functionality of the boxes. 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 the protection claimed also relates. It can therefore be produced in other forms and dimensions with the most suitable materials in order to remain in the spirit of the claims.

Claims (3)

  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 at the opposite ends of the sides, characterized in that a projection / end support (2) is provided (e) placed on the contiguous vertical edge smaller protrusion / support (3). 2. stackable-built-in box according to the preceding claim, characterized in that on the two contiguous interior angles of the upper half of the box were respectively provided vertical grooves forming an integral part of the angle. 3. stackable-built-in box according to the preceding claim, characterized in that said projection / end support has been provided so that it can be incorporated in boxes when these are provided to contain high weights and so that it can be removed when the boxes25 are designed to contain light weights, all of this being provided in an operational manner so that the former can be embedded with the latter without   damage the functionality of the boxes.
