Abstract

Inviolable side closure for box, preferably cardboard, characterized in that each side flap (1) carries a cross section to form the flange (2) preferably rectangular, said cut being made at the outer corner opposite the outer edge and the line of unión between the front wing (8) and the side flap (1), carrying in the corner in the rear side flap (5) the closing hole (6) preferably rectangular, measures proportional to the flange (2) and size slightly higher, located at the outer corner near the line of connection between the rear side flap (5) and the rear wing (10), also carrying in the middle flap (3) a hole (4) preferably rectangular and elongated, located in the outer corner next to the line of unión between the middle flap (3) and the lower middle flap (7), with the hole (4) and the closing hole (6) coinciding in the fold, and the closing hole (6) and the tab (2) also also coinciding in the folding, carrying a climbing line (11) with discontinuous scratching on the fold line separating each side flap (1) from the front wing (8).

Description

Inviolable side closure for box.

Object of the invention.

The present invention relates to an inviolable side closure for preferably cardboard box.

Background of the invention.

Currently the market offers different types and forms of closures for cardboard boxes or similar material. In this case it would be a type of permanent closure, making the product inaccessible until it reaches its destination. In general, said closures consist of elements outside the box, which help to fix the opening component, such as adhesive tapes or adhesives in general, as well as elements of the box material that can act as closures or tabs that fit certain places. These usually require a use of extra material or also some manipulation, which sometimes can be uncomfortable and other times it can give little security to the closure element.

The invention presented here achieves an effective, simplified closure and with significant cost savings, compared to other types of closures.

Description of the invention

The invention presented below greatly improves the functional characteristics of models of similar uses, without modifying the design of the box itself, without added elements and guaranteeing maximum strength and ease of use, making accidental opening impossible.

The forming of the box starts from a sheet preferably of cardboard and is carried out in a conventional manner. For the realization of the elements involved in the closure, a transverse cut with a die is made in each lateral fin of the front wing of the lid and also a hole by means of a die in each rear lateral fin of the rear wing of the box. At the junction between each lateral fin with the front wing of the lid, a line is drawn longitudinally, also made by means of a die and with a broken line. Once the box is closed, access to the interior is done by tearing the broken line. Any attempt of opening outside the recipient would leave a visible mark on the box, thus preventing unwanted discrete manipulations.

The characteristics and advantages of the invention can be seen more clearly from the following detailed description of a preferred embodiment, given only by way of illustrative and non-limiting example, with reference to the accompanying figures.

Description of a preferred embodiment.

The detailed description of a preferred embodiment of the invention will be carried out in the following with the help of the attached drawings, through which the same numerical references are used to designate the same or similar parts, and have in Account the explanation explained of the invention.

Figure 1 shows a view of the sheet with which the box is formed, preferably of cardboard, and whose folding is carried out in a conventional manner. On both lateral edges of the front wing (8) of the cover (9) the lateral fins (1) are placed on which a transverse cut with a die is made to form a flange (2) that will preferably be rectangular. Said cut is made in the outer corner opposite the outer edge and the line of connection between the front wing (8) and the lateral fin (1). On the opposite side of the sheet, a closing hole (6) is made in the rear side flap (5) by means of a die, the shape of which will preferably be rectangular, of proportional measures to the flange (2) and of slightly larger size, and located in the outer corner near the junction line between the rear side flap (5) and the rear wing (10). A preferably rectangular and elongated hole (4) is also made in the middle fin (3), which is located in the outer corner next to the junction line between the middle fin (3) and the lower middle fin (7), and which serves as reinforcement to the closure of the box.

Figure 2 shows a view of the folding of the middle fin (3) on the rear lateral fin (5). The lower middle fin (7) bends until it touches the rear lateral fin (5) on its outer part. The position of the hole (4) and the closing hole (6) is observed.

Figure 3 shows a final view of the folding of the middle fin (3) on the rear lateral fin (5). The middle flap (3) bends until it touches the rear side flap (5) in its inner part so that the hole (4) and the closing hole (6) overlap, being coincident in folding.

Figure 4 shows a view of the lateral fin (1) with the flange (2) deployed that bends inwards until touching said lateral fin (1). On the folding line that separates each lateral fin (1) from the front wing (8) a climbing line (11) has been drawn, made by means of a die, and with dashed dashes.

Figure 5 shows a sectional view of the closure of the box. Each lateral fin (1) is introduced into the space

10 corresponding to the gap left between the rear lateral fin (5) and the lower middle fin (7). The flange (2), which is coincident with the closing hole (6), is thus embedded in said closing hole (6) such that the lid (9) can no longer be opened. From here, to access the content we must proceed to tear the climbing lines (11).

It should be understood that the invention has been described according to a preferred embodiment thereof, so it may be subject to modifications as long as it does not imply any alteration of the basis of said invention,

15 such modifications may affect the shape, size or manufacturing materials.
