Description

D E S C R I P C I O N

Box for horticultural products.

SECTOR OF THE TECHNIQUE

The present invention refers to a box made of cardboard and provided with a plastic lid, preferably PET, for transportation, marketing and exhibition of small fruit and vegetable products such as red berries, raspberries, etc., although it could be equally applicable to larger products.

The box has the particularity of having upper closure means that allow the anchoring and retaining of the lid in the closed position without the need for any manipulation.

BACKGROUND OF THE INVENTION

Numerous and varied types of boxes are known, usually cardboard or plastic, for horticultural products, and among them small products, such as raspberries, blackberries, etc., so that in all cases the particularity of the boxes is that are open superiorly, with the problems that this entails.

In order to obviate this problem, plastic covers are known formally and dimensionally adapted to the embouchure of this type of boxes, however, this type of covers are not properly stabilized being easily removable.

The applicant himself is the owner of the utility model ES1191208U in which a box for horticultural products of the type referred to above is described, and which is constituted from the development of a cardboard sheet that presents a central and majority constitutive of the fund, four lateral sectors that constitute the lateral ones of the box, that are intercalated between small diagonal sectors that determine a box of octagonal base essentially quadrangular, but with its edges chamfered, in such a way that the sectors that form two of the walls opposite are extended in two contiguous extensions one occupying and forming the corresponding minor side of the octagon and another that is inside the box, attached to the opposite wall and fixed to it by gluing, all in such a way that of the walls that the flanges form flanges that fold outwards and serve as means of wedging the inner edge of the lid.

Although this solution allows the cover to be secured to the box, it has the disadvantage that the anchoring tabs provided in the chamfers must be manually folded outwards, a maneuver that may not be evident to certain users, as well as being a solution difficult to unlock.

DESCRIPTION OF THE INVENTION

The box of the invention solves in a fully satisfactory manner the aforementioned problems, based on a simple but effective solution.

To do so, and starting from structural characteristics similar to the box described in said utility model ES1191208U in which an inverted pyramidal trunk configuration box is defined, with octagonal base, with two major walls two smaller walls and four small walls interspersed between these as chamfers, the box of the invention presents an important novelty that makes the anchoring of the lid is performed automatically, resulting also much easier than unlocking the lid.

More specifically, it has been foreseen that both the larger side walls and the sectors of the corners contiguous thereto are prolonged in a single and longitudinal flange, with a gluing band complementary to another provided for that purpose on the outer face of said wall lateral, in such a way that in the assembly of the box said two zones are fixed to each other. The flange has a stepped shape, so that its ends have a smaller amplitude than its central area, which correspond to the larger walls, so that the gluing band exclusively affects the larger walls, whereby the flange portion of smaller size corresponding to the lateral sectors will be slightly separated from the body of the box. In this way, it is achieved that the smaller part of the tab in correspondence with the lateral sectors, determine a kind of harpoon or wedge that significantly facilitates the maneuver of implantation of the lid, which is self-guided and is elastically deformed until reaching the free edge area of the flange, being locked in it.

It only remains to point out, finally, that this solution supposes a reinforcement of the embouchure of the box, which results, as an additional advantage, in a longer useful life of the latter.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred embodiment of the same, a set of drawings is included as an integral part of said description. where, with illustrative and non-limiting character, the following has been represented:

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures shown, it can be seen how the box of the invention is obtained from the development of a rectangular cardboard sheet, in which a central sector (1) is defined, essentially rectangular with truncated edges constituting the bottom of the box, from which emerge two opposite smaller walls (2) and two larger walls (2 ') in opposition, determining four of the eight side walls of the box. The two larger side walls (2 ') extend laterally by means of respective trapezoidal sectors (3) which determine the four remaining walls of the box, like chamfers, and which are disposed in correspondence with the oblique edges (4) that they are defined in correspondence with the corners of the central sector (1). These sectors (3) are fixed in the assembly to the smaller side walls (2) through flaps (5) by gluing, having a greater height than said smaller side walls (2), forming reinforcements and aeration windows. Additionally, said sectors (3) include underneath arched edges (3 ') that determine lower windows of complementary aeration for the box.

Well, according to the essence of the invention, it has been provided that in correspondence with the side walls (2 ') and affecting to a lesser extent the sectors (3) that cover the corners, are established lashes (6) stepped, provided with a gluing band (7), such that in the assembly, said gluing band is complemented by another provided on the external face of the respective larger side wall (2 '), causing that when bending over itself same and adhering to the outer face, the flange (6) is arranged parallel to the wall from which they emerge. On the other hand, the smaller part of lower height (6 ') of the flange (6) that is in correspondence with the lateral sectors (3), is not provided with means of gluing, so that after assembly, these parts of the smaller tab will be slightly separated from the body of the box. In this way, it is achieved that the part of lower height (6 ') of the flange in correspondence with the lateral sectors (3), determines a kind of harpoon or wedge in which the inner edge (9) of the cover plastic (8).

For its part, the plastic cover (8) is provided with a constriction or internal narrowing perimeter in the chamfers. In this way, and as has been said previously, the coupling maneuver of the lid (8) is automatic, by simple pressing and elastic deformation of the lid, which is wedged in the harpoon or external wedge determined in the assembly by the folding of the eyelashes (6) and its fixing by partial gluing (only of the larger part of the eyelashes) on the external face of the respective larger side wall (2 '), and leaving the box free and partially separated from the box. part of lower height (6 ') of the flange in correspondence with the lateral sectors (3). Given the strategic position in which these interlocking means are located, the unlocking maneuver of the lid is equally simple as the lid and the mouth of the box in these areas of the chamfers are easily deformable.
