Abstract

Cardboard box with lid, which is preferably provided for the transport of fish or similar products, and being formed from the development of a cardboard sheet with fold lines delimiting a central sector with extensions, which in the assembly will determine the bottom, the lateral and corresponding ends, is characterized because both the sheet for obtaining the box, and the sheet for obtaining the cover, have a quadrangular sector common to the ends of the sides and the ends, delimited with respect to said lateral and end walls by means of two fold lines that, in combination with a line of diagonal folding of such quadrangular sectors, allow the folding of these and their superposition on the surface of the end walls, having foreseen that said end walls are extended by their free edge in a trapezoidal flap that continues in a rectangular extension with continuous bending line, for the pleg of this and its arrangement, after the folding of the trapezoidal flap, between the folded quadrangular sectors and the surface of the respective head, keeping the body of the box and, where appropriate, the lid.

Description

Cardboard box with lid.

Object of the invention

The present invention relates to a box of cardboard with lid, which is intended for the transport of edible products, preferably fish and the like.

The object of the invention is to get a box which can be considered airtight, based on a continuity between lateral and front, which prevents the passage of liquid to outside, collaborating on it a layer of paraffin or other product waterproofing, applied on the inner surface of the own box

Background of the invention

The transport of fish and similar products It can be done in plastic boxes that, of course, do not they are recyclable, in addition to the fact that their cost is high by virtue that complex molds are required that are undoubtedly expensive. In addition, plastic boxes usually have a weight tall.

There is no doubt that cardboard boxes result from low cost, light and very practical, although for products such as fish that usually releases water are not valid, since on the one hand in the cartons normally set an interruption surface between lateral and front, allowing the passage of water, which causes the box to get wet and end by break.

Description of the invention

The box that is recommended, planned precisely for the transport of fish, without discarding other products, It presents some peculiarities based on which they are solved the problems referred to in the previous section.

More specifically, the box of the invention is constitutes from the development of a rectangular sheet of cardboard, with fold lines so that the assembly determines bottom, the sides and the ends, deriving said sides and Treasurers of the central sector constituting the fund, all as it is conventional, with the special feature that the extremes of the sides and ends of the heads are joined through a quadrangular sector common to both ends and delimited regarding them by means of bending lines, in such a way that that sector established in each corner of the cardboard sheet, presents a diagonal fold line that originates parts triangular that fold and hang on themselves, in correspondence with the outer surface of the box, which is get based on the common bending lines of the formed sector by those two triangular parts with the respective ends of the sides and the heads.

The box thus constituted lacks the classic interruption between the sides and the heads, settling in the corresponding internal corners or dihedrals a continuity surface that prevents the passage of water to the outside, preventing also the penetration of moisture through the cardboard, such as consequence of the inner surface of the cardboard sheet and therefore the box is provided with a layer of paraffin or other Any product with a waterproof character.

Another novelty feature of the box is the way of being perfectly armed, without the possibility of disarming, for which it is expected that the testeros extend, in correspondence with its longitudinal edge, in a trapezoidal flap that through its smaller and more external base is continued in a rectangular conformation with three consecutive fold lines, of so that the trapezoidal flap of each testator is lowered the exterior of this one being attached to the upper zone of the same and being retained by a folded rectangular extension that fits between the folded triangular parts of the sectors referred to previously and the surface of the testeros themselves, thus the box being armed without the need for staples or glued, allowing to transport fish and similar products with total guarantee and without risk that the box is damaged by moisture, and that the water that can release the fish will not be filtered by any side when the case is sealed for continuity surface as per the waterproofing layer applied to the inner surface of it.

This box is complemented by a lid with the same characteristics, although of a slightly larger contour, for It can be attached in an envelope to the box, presenting the sectors and flaps of the front folded inwards in place outside as in the box, determining that the external surface of the lid, and ultimately of the closed box, Be totally smooth.

The advantages of the box with its lid, compared to the conventional ones of plastic, are evident as they have commented previously, and correspond to a very remarkable saving in the manufacturing; to a greater lightness; more easily and quickly in the assembly, as well as its recyclable character.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, is accompanied as an integral part of that description, a set of drawings in where illustrative and not limiting, it has been represented the next:

Figure 1.- Shows a corresponding view to the development of the cardboard sheet from which it is obtained The box of the invention.

Figure 2.- Shows a perspective view of the armed box.

Figure 3.- Shows a perspective view of the armed lid.

Figure 4.- Shows a perspective of the box and the cover in the initial position of enveloping coupling of said lid on the box.

Preferred Embodiment of the Invention

As you can see in the referred figures, the box of the invention is obtained from the development of a cardboard sheet with the surface that will constitute the interior thereof, provided with a layer of paraffin or other product of waterproofing

In the development of said cardboard sheet have planned bending lines that give rise to a central sector and constitutive rectangular bottom (1), two extensions longitudinal constituents of the sides (2), and two transverse extensions constituting the testeros (3).

The sides (2) and the heads (3) are joined by their ends through respective sectors quadrangular (4) delimited by corresponding lines of fold, whose sectors (4) are affected by a fold line diagonal (5) that gives rise to two triangular parts equal to, in the assembly of the box, fold and overlap each other, attached to the outer face of the heads (3).

On the other hand, said testeros (3) extend in a trapecial flap (6) delimited from the longitudinal edge of the respective tester (3) by means of a fold line (7) that allows the folded outward of said trapezoidal flap (6), with the particularity that it continues in an extension rectangular (8) with contiguous bending lines (9), allowing the folded with such a rectangular extension (8) and its fit between the folded sectors (4) and the corresponding external surface testero (3), with which an easy assembly of the box is achieved and to at the same time a security in the maintenance of said assembly.

The box is complemented by a lid that obtained in the same way, specifically from the development of a cardboard sheet like the one in figure 1, but with slightly greater amplitude to obtain the cover that engages in an enveloping way on the box described above, as shown in the figure 6.

In figures 3 and 4, in which the lid is seen, the parts or elements are the same as those referred to for box but with the references commented with the sign or character ('). That is, said cover comprises a bottom (1 '), about lateral (2 '), some front (3'), quadrangular sectors (4 ') with the diagonal fold line (5'), the flaps (6 '), etc, with the only variation that in the case of the cover the sectors home runs (4 ') are folded inwards, just like the flap (6 '), that is, the arming is carried out and maintained on the inside instead of on the outside as in the box.

Claims (4)
