PROTECTIVE PACKAGING FOR SUITCASES

Abstract

Suitcase protector comprising a cardboard packaging, characterised by the fact that it is made from the development of a die-cut sheet of cardboard, in which a rectangular, horizontally elongated, major section is defined, which, by means of vertical folding lines, determines the two major (1-1′) and minor (2 2′) sides of a rectangular prismatic container, which by means of vertical folding lines determine the two larger (1-1′) and smaller (2 2′) sides of a rectangular prismatic container.

Description

TECHNICAL FIELD

The present invention relates to a protective packaging for suitcases whose evident purpose is to provide a means of protection for suitcases, especially designed for use in airports, bus stations, train stations and the like. The object of the invention is to provide a means which, in addition to protecting the suitcase against knocks, scratches and the like, determines a means of evidencing any tampering with the suitcase. The invention aims to provide a new protective means, with which, once implemented, the suitcase can be used conventionally, i.e., leaving its telescopic handle and wheels operational, all with a more ecological and environmentally friendly structure, 100% recyclable.

BACKGROUND OF THE INVENTION

As is well known, when travelling on planes, buses and even trains, if the suitcases exceed a certain volume, they must be stored in the cargo hold or in receptacles separate from the passenger, which makes it possible for them to be tampered with, for example to remove belongings contained in them. In an attempt to avoid this problem, there are known packing services in which the suitcase is rolled up a large number of times with a transparent plastic film, so that removing the film is a significant waste of time that tends to discourage any opportunist, as well as highlighting any tampering manoeuvre. The fundamental problem with this system is that it involves the use of a large volume of plastic, with the environmental problem that this entails.

EXPLANATION OF THE INVENTION

The recommended protective packaging for suitcases solves the above-mentioned problem in a fully satisfactory manner, based on a simple but effective solution. More specifically, the packaging of the invention is based on a prismatic cardboard box, with an elongated rectangular base, in short, of dimensions in accordance with the suitcase to be contained inside, obtained from the development of a die-cut cardboard sheet, in which, from a horizontally elongated rectangular sector, with four vertical folding lines. The four side walls of the box and the closing flange are defined by gluing the box with four vertical folding lines in order to obtain a foldable and easy to assemble tubular body, in which only the bottom and the upper base need to be assembled as described below.

From the lower edges of the side walls emerge four tabs with their corresponding folding lines, with double-sided adhesive tape and cut-outs which, when assembled, provide recesses for the wheels of the suitcase. Once assembled, the lower side cannot be removed due to the aforementioned adhesive.

Four folding flaps also emerge from the upper edges of the side walls of the case, also equipped with adhesive for gluing them together, and with cut-outs which provide a window for the telescopic handle of the case.

One of these flaps, specifically the one linked to one of the larger sides, will have a longitudinal tear line that allows the user to access the inside of the container by tearing it once the journey has been completed.

Finally, it only remains to be noted that the smaller side walls of the box may also include tear lines which determine the respective rectangular windows for access to the manual grip handle which some cases have on one of their smaller side walls. The following advantages are derived from this structure: 100% ecological, recyclable and environmentally friendly product, which avoids the use of plastics; easier (and less time-consuming) installation and removal; offers a higher level of protection to the case against knocks and scratches; inviolable system that prevents any type of tampering with it; it offers a large labelable surface, ideal for advertising; and improves the stability of the luggage in the cargo hold, as it is a perfectly prismatic-rectangular body.

BRIEF DESCRIPTION OF THE DRAWINGS

In order to complement the description to be given below and in order to help a better understanding of the characteristics of the invention, in accordance with a preferred example of its practical application, a set of drawings is included as an integral part of this description, in which the following has been shown for illustrative and non-limiting purposes:

FIG. 2.—Shows a side-bottom perspective view of the packaging of the previous figure.

FIG. 3.—Shows a perspective view of the packaging with the bottom assembled, and with its upper mouth open.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the above figures, it can be seen that the packaging of the invention is made from the development of a die-cut sheet of cardboard, in which a rectangular, horizontally elongated, majority sector is defined, which by means of vertical folding lines determines the two larger (1-1′) and smaller (2-2′) sides of a rectangular prismatic container. The prism is formed by attaching a tab (3) associated laterally to one of the larger sides (1) and fixed to the free smaller side (2), as shown in FIG. 3, with the particularity that from the lower edges of the larger sides (1-1′) emerge larger tabs (4-4′) with their corresponding folding lines, the smaller sides (2-2′) have smaller flaps (5-5′), all of which are intended to form the bottom by gluing them together with double-sided adhesive tape, not shown in the figures, which will be supplied attached to one of these flaps, the other side of which will be protected with waxed or siliconized paper that will be removed when the box is assembled, the larger flanges (4-4′) have rectangular recesses (6) that affect both their inner and outer corners, while the smaller flanges have rectangular recesses (7) that only affect their inner corners, so that when the bottom is assembled, both recesses create windows for the wheels of the suitcase to be packed.

As for the upper mouth of the packaging, in correspondence with the upper edges of the walls or larger side faces (1-1′) there is a front flap (10) and a rear flap (9), the former with a “U” cut-out (13) on its free upper edge, while the latter incorporates a rectangular cut-out (14) in correspondence with the hinged area of the said flap, and which partially affects the upper end of said larger side face (1′), while from the smaller side faces (2-2′) emerge two smaller tabs (11-11′) which include an “L” shaped recess (12) on their rear and upper edge, so that these recesses coincide in the closure of the upper mouth of the container, forming a single common window through which the telescopic handle of the suitcase can be extracted.

For this closure, once the suitcase has been inserted into the suitcase in the correct orientation, the smaller tabs (11-11′) are folded, then the front tab (10), and finally, after removing the corresponding sheet of paraffin paper laid on one or more double-sided adhesives fixed to the inside face of the rear tab (9), this tab is fixed immovably on the front tab (10).

The rear flap (9), the only one visible once the container is closed, shall have a longitudinal tear line (15) that allows the gluing area of the said flap to be separated from the front flap, so that in order to remove the suitcase, the said tear line must be broken, thus showing that it has been tampered with.

Finally, it only remains to point out that the smaller side faces are susceptible of incorporating rectangular climbing lines (16) in their middle area, determining windows for the passage of the corresponding manual grip handle that some suitcases incorporate in one of their side faces.
