Description

Anti-bubble closure.

The present invention aims at a closure intended for aseptic containers prismatic, cylindrical or similar, commonly known as "tetrabrik", and whose fundamental purpose is to avoid the bubbling that generally It is produced by emptying the liquid contained in these containers, with the consequent splashes and spills that accidentally occur thus.

Current state of the art

The containers referenced in the previous paragraph they are constituted by an outer cover, waterproof and resistant, complemented by a second internal cover, perfect and fully adhered to the outside, of suitable material for guarantee the total asepsis of the liquid contained therein, constituting the inner insulating coating of the container.

These containers have an exit hole for its emptying, provided with a suitable closure that, before the first utilization remains completely closed and guaranteeing tightness, and once opened for the first time, allows closing safe while no more liquid must be drawn from inside.

However, the existence of this unique exit hole for emptying causes the logical bubbling of the liquid when it is approaching, because by that same hole it must penetrate the air that will occupy the space released inside the packaging, annoying bubbling due to splashes and spills accidental that usually causes.

Object of the invention

The closure object of the present invention offers a practical and fully effective solution to the problem mentioned above of bubbling, as described below.

It consists essentially of the anti-drip closure object of this invention in the additional provision of a tab, fixed next to the drain hole closing of the container, whose tongue has, at its end, a conical wedge, located on the underside of the mentioned tab and that is going to position yourself on a circular hole in the face top of the container, hole that affects only the cover outside of the container but without drilling the second inner cover, which is the aseptic coating and interior insulator of the container.

The arrangement of this tab allows that, in a first use, pressing properly on the end of the tongue, the conical wedge, is inserted through the hole circular of the outer cover, piercing the second cover, thereby producing an auxiliary hole that allows entry of the air inside the container when it is loaded, totally eliminating the possibility of annoying occurrence bubbling, since the air will not penetrate inside the container by the drain hole but for the new hole made by the Conical wedge action.

Once the emptying of the amount of desired liquid in that first use, the auxiliary orifice of air inlet will be plugged with the conical wedge itself of the end of the tongue, which will ensure the closure and asepsis of the content.

By emptying the contents later of the container, while opening the drain hole, also will raise the conical wedge to open the auxiliary entrance hole of air, and so on.

Graphic information

In order to complete the description of the Anti-bubble closure object of this invention, are attached drawings in which, by way of non-limiting example, they have been represented some practical embodiments of said closure.

In these drawings,

Description

According to these drawings, the closure anti-rubbing object of the present invention applicable to packaging type "tetrabrik" (1), is constituted by a tongue (2), in whose limb, and its lower face, has a conical wedge (3). The tongue (2) is fixed on the edge of the base (4) of the closure trapdoor (5).

In the embodiment represented in figures 1 to 6, the tongue (2) is attached to the end of the trapdoor (5) of the closing the drain hole, and in the variant embodiment with screw cap closure (6) the tongue is preferably fixed at the edge of the base (7) of said closure.

The positioning of the tongue (2), such as It is clearly depicted in Figures 5 and 6, it makes the wedge conical (3) is placed on the circular hole (8) made on the outer cover (9) of the container (1). A pressure action manual on the end of the tongue (2) causes the wedge tapered (3) puncture the second inner cover (10) of the container (1), defining then the auxiliary air inlet hole (11) the which, when the contents of the package should not be fully addressed, It will be closed by the tapered wedge itself (3), as shown by the figure 6.

It is clear that when the user wants to move the rest or part of the liquid in the container should open both the closure (5) or (6) how to manually raise the conical wedge (3) to avoid the bubbling.

The aforementioned conical wedge (3), of course, it can have any other form that allows the perforation of the internal cover (10), such as a pyramid shape or sharp.

Described sufficiently the object of the In the present invention, it should be noted that any variation in dimensions, shapes and appearance of the anti-drip closure that has been described, they will not alter the essentiality of it, leaving summarized in the following claims.

Claims (6)

1. Anti-drip closure, for aseptic containers commonly referred to as "tetrabrik" (1), characterized by comprising in the type of trap door closure (5), emerging from its base (4) a tongue (2), at the end of which, and by its inferior face, it has a conical wedge (3), being. 2. Anti-drip closure, according to the preceding claim, characterized in that the flange (2) is fixed to the edge of the base (4) of the closing flap itself (5). 3. Anti-drip closure, according to claims 1 and 2, characterized in that the length and positioning of the tongue (2) allows the conical wedge (3) to coincide on a circular hole (8) made in the outer cover (9) of the container (1), so that by exerting a manual pressure on the conical wedge (3) it punches the second inner cover (10) of the container (1), then defining an auxiliary hole (11) for the air inlet, with the consequent Elimination of the cause of bubbling. 4. Anti-drip closure, according to claim 3, characterized in that the auxiliary orifice (11) for air inlet is closed with total tightness, when the contents of the container (1) are not covered, by the plug action of the conical wedge itself (3). 5. Anti-drip closure, according to the preceding claims, characterized in that the wedge (3) of the tongue (2) emerges from the base (7) of the closure itself. 6. Anti-drip closure, according to the preceding claims, characterized in that when the container has the screw-type closure (6), the tongue (2) emerges from the base (7) of the closure itself.
