Pre-packaging tray in cardboard with front.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a tray for prepackaging in cardboard with cover that aims cover the mouth of the tray full of fruits or others products protecting them from the outside, while the tray It can be stacked while full of the corresponding product.

Background of the invention

The current cardboard packaging with a lid on the that this is part of the container structure itself, as per example inventions E00914784 and Utility Model No. 9702184, usually have problems for stacking in vacuum, needing a more space In addition, these and other containers, such as Utility Models numbers 153006 and 9501335, used in the transport of perishable products, have the disadvantage of that it is not possible to store them by fitting them inside others.

Description of the invention

To achieve the objectives and avoid drawbacks mentioned in the previous sections, the invention proposes a tray for pre-packaging in cardboard with cover that is determined from a bottom and four walls lateral, characterized because they converge at their ends in affected corner portions, in proximity to its edge upper, with grooves where fins are inserted and fitted complementary that are part of a closing lid of the container mouth.

This ensures immobilization and cover anchor that protects the product housed inside the tray.

The corner portions are sectors that they tear from the ends of two of the side walls, pulling in turn of these sectors some flaps, on the which the extreme sections of the other two walls are attached even sides, thus forming and assembling the tray respective.

Another feature of the invention is that side walls and corner portions have a smooth convergent tilt to the bottom. Thus, it is possible to stack empty trays by inserting ones inside others and also stack containers or trays full of product, of so that in this case, an upper tray will rest on the lid of a lower tray, concentrating the weight of the upper tray especially in proximity to the corners of the area where the fins they fit into the grooves of the corner portions.

Another feature of the invention is that at minus two opposite side walls include on their free sides aeration recesses, also intended to facilitate the cover manipulation.

Another feature is that the cover fits  in addition to the plantar interior space limited by Four side walls.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 2.- Shows a perspective view of The fully armed box.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the tray for prepackaging in cardboard with cover it comprises in principle a rectangular bottom 1 with its corners chamfered 2, two major side walls or sides 3, two minor side walls or front walls 4 and narrow portions 5 sidewall arranged in correspondence with the corners chamfered 2.

The sides and heads could have perfectly the same dimensions, with which the tray It would then have a quadrangular configuration.

Said portions 5 start from the ends of sides 3, while prolonging in extreme flaps 6, on which the extreme sections of the heads are attached 4 thus assembling the tray.

Said corner portions 5 possess some horizontal grooves 7 where complementary fins fit together  8 that are part of the cover 9 that covers the product located inside the tray

Side walls 3 and 4 and portions corner 5 have a gentle convergent inclination towards the bottom 1 to allow the fitting of empty trays within others occupying a small space and also to allow stacking of product-filled trays, where a upper tray will sit on the lid 9 of a lower tray, the weight being concentrated essentially in the areas near the corner fins 8.

In correspondence with the free edges of the side walls are defined trapecial aeration recesses 10, in a case made on sides 3 and in the case of limited by the free edge of them and by some upper facing parts of the end flaps 6.

The recesses 10 also serve to be able to insert the fingers in order to facilitate the manipulation of the lid, being able to open and close it.

The tray is made of cardboard, while the lid It can be of any material.

The advantage of the tray of the invention is the possibility of closing said tray and protecting the merchandise, through its corresponding cover, which fits perfectly fitted to the tray, which prevents its displacement or lost. In addition, it facilitates storage and empty transport, the tray and lid can be stacked separately.
