Description

Plastic case-box blown.

The present invention refers to a device for transporting delicate objects.

In particular, the present invention makes reference to a device for transport and storage that It is especially suitable for use in transport aerial of bottles, although the invention is not necessarily limited to this kind of object stored and / or transported, or to that class Of transport.

Due to the inclusion restrictions of liquids in aircraft cabins, international shipping of Bottled wines, particularly high quality wines, have been Restricted

Formerly, these bottles were sent by plane, in the passenger cabin. The cabin is the ideal place for transport, because the environmental conditions are optimal and little changeable and more than enough space, since shipments They are reduced to a very limited number of bottles.

By limiting the introduction of liquids in the cabin, shipping by plane is no longer viable, because the environmental conditions of humidity, temperature and vibrations / movement in the aircraft hold are so hard that They affect the quality of the wine to be sent.

Therefore, a new one is necessary packaging for high quality wine bottles that allows shipping of economically a reduced number of bottles and that protects the bottles of the thermal oscillations of the winery, of the vibrations and possible blows.

In accordance with the present invention, it is given to know a new packaging, which is suitable for application before indicated, and consisting of two pieces of blown plastic, double wall, articulated by a hinged joint that joins them by one from its sides and presenting a closing system of the case-box on the other, so that the box-case defines an interior space for to house objects, in which in the mentioned interior space two forming elements that, with the case-box in closed position, they form at least one adjusted reception opening of an article.

The box-case object of the The present invention takes the form of a suitcase with a double wall that defines a camera between walls. This implies that the box Case has great mechanical resistance, especially in front shock, and high resistance to thermal variations, thanks to the chamber between walls, but that presents costs of reduced manufacturing

The shaping elements are the elements additional that allow the adjustment of the element to contain (preferably a bottle), but allow the main object be a plastic double wall case-box blown, with the advantages of strength and low manufacturing cost That implies.

Preferably, the forming elements they will comprise a structural element of absorption of movements and / or blows that could affect the object or objects stored in the box-case.

The present invention provides two embodiments. Particularly advantageous individuals. In one embodiment, the forming element is a foam with a geometry that defines the cited adjusted reception gap of the article or articles. In this case, the foam also acts as a structural element of absorption. In another embodiment, the forming element is a expanded polystyrene (structural absorption element) on the that a thermoformed polymer sheet is placed, which allows a Perfect fit to the item or items to keep / transport. The said thermoformed polymer sheet may be flocked. Combinations of the embodiments are also possible. preferred.

Even more preferably, the space between the double walls of the articulated pieces that make up the box-case may be filled with a substance insulating. The insulating substance may be advantageously Expanded polyurethane.

For the introduction of the insulating substance, preferably, each one of the mentioned pieces presents the minus two holes, one larger to allow injection of the insulating substance and at least one minor (preferably more than one) to allow the air displaced by the substance to escape Insulator during injection.

The present invention also provides that the outer surface of each of the quotations pieces present, of optionally, a series of adjacent incoming and outgoing and parallel, being the incoming and outgoing of each of the conjugated pieces, such that the entrees of a case-box located above the box-case, and the projections of bliss case-box penetrate the entrances of the other case-box located above.

Figure 12 shows a perspective view of another preferred embodiment that can be shared by all embodiments of the preceding figures 1 to 11.

Figures 1 to 8 show an embodiment of a case-box according to the present invention.

The box-case (1) shown It takes the form of a hinged suitcase. The box-case or suitcase (1) is formed by two pieces joined by hinge joints (14). The pieces are made of blown plastic according to technique known and have a double wall (11), (12). The pieces too define a closure (19) and a handle (18) for transport.

The space (15) defined between those mentioned double walls (11), (12) is filled with expanded polyurethane as insulating substance, which significantly increases the mechanical resistance and resistance to thermal variations of the product.

The polyurethane can be injected into space (15) defined between the double walls (11), (12) through a Discreet entry hole in the inside of the suitcase, for example, 10 mm in diameter (not shown in the figures). Saying Inlet hole allows the entry of an injection head which, with an overpressure of, for example, 3 bar, provides a amount of polyurethane in liquid phase.

In turn, 1 to 6 holes have been made 0.8 mm diameter (depending on the interior geometry and the suitcase size) through which the air is evacuated displaced from inside the chamber or space (15) between the walls (11), (12) during the reaction of passage of liquid to solid of the polyurethane components that have been injected.

As you can see, the plastic parts made according to the technique of blown plastic have a neutral interior, that is, without shapes, which is not especially Suitable for transporting delicate objects.

To do this, in the case of the example of the figures 1 to 8, two forming elements (16), (162) have been placed made of a foam or "foam" (for example polystyrene, polyurethane, etc ...) whose function is the absorption of movements and / or blows. In the case shown, one of the elements shapers (16) have a gap (161) with adjusted reception of the bottles (100) to be preserved and / or transported. Said element shaper can be a single piece or, for ease of manufacturing, be composed of a lower sheet of 5 to 15 mm thick and another die cut layer according to the profile of the bottle (100) In the continuous piece is attached a new sheet of foam (62) between 5 and 15 mm thick which has as its function press directly on the bottle (100) once the Case-box (1) is closed.

Figure 9 presents a variant embodiment in which the foam sheets are replaced by two different elements. At the bottom and in contact with the bottom wall of the suitcase is placed a polystyrene element expanded (not shown in the figures) that supports the weight of bottles The geometry of this element allows to support Bottles of different geometries. This item does not appear at user view, since it is covered by the thermoforming upper (15).

The upper thermoforming (15) is a polymer sheet (PP, PE, ...) thermoforming that can present a flocking finish. The thermoformed sheet (15) has a geometry that defines a gap that adapts with great precision to the bottle outline (100).

Figures 10 and 11 show paths variants of embodiment with different numbers of elements delicate (bottles -100-) transported. In the figures corresponding to the different variants, identical numerals they refer to equal or equivalent elements.

Figure 12 shows a variant of embodiment in which they have been arranged, on the outer surface of the suitcase (1), of chromatic strips (21), (22) that indicate the outside and inside temperature in the suitcase, to control the transport conditions. A set has also been arranged (23) of adjacent and parallel incoming and outgoing. Such incoming adjacent and parallel of each of the pieces that make up a suitcase (1) are conjugated, so that the entrances of a suitcase or case-box receive the projections of the adjacent suitcase and vice versa. This way you can stack several case-boxes (1), without movement cross between suitcases.

In short, the copies shown show a container of delicate objects of low cost that presents a strong protection against mechanical impacts and high resistance mechanical, which offers thermal and light protection. All of it being able to present an exquisite exterior presentation, being adaptable to each specific case, recyclable, long life and reusable as a suitcase for other delicate items or as suitcase in general.

In general, everything that does not affect, alter, change or modify the essence of what is described, it will be understood within the present invention.

While the invention has been described with respect to examples of preferred embodiments, these are not due consider limiting the invention, which will be defined by the broader interpretation of the following claims.
