Description

Airtight bottle cap.

Object of the invention

The present invention relates to a plug Airtight bottles that have application in the dedicated industry to the manufacture of bottles intended for liquid containment for its transport until the moment of its consumption by a user, constituting a sturdy plug that offers a high security given its tightness, preventing an unwanted exit of the liquid contained in the bottle, while it is fast and easy to manufacture with the consequent cost reduction and appreciation by its user.

Background of the invention

There is currently a wide variety of bottles, canteens and all kinds of containers intended for liquid containment, for transport by a user, for example during a field trip, in order to consume said liquid contained at the time desired by the user.

A great variety is known in terms of materials of this type of bottles, as well as their dimensions, which are determined by the use of these containers On the one hand its dimensions must not exceed those that allow a comfortable carrying of the bottle by a user without causing excessive fatigue in it. On the other hand the materials must be resistant to breakage in case of falling the bottle, being usually used for it different light and resistant plastics and materials such as the aluminum.

Also a fundamental requirement is that the stopper of these bottles has an airtight character, that is to say prevent leaks of the liquid contained in a way unwanted For this there are caps for this type of bottles that incorporate a joint, usually of polymeric material and toric configuration, which is arranged independently around the neck of the cap. The downside that this solution presents is that during normal use of the cap of the bottle, after successive openings and closures of the same, the board is moves from its initial location, and progressively loses its initial form, so the loss of the same when you stop exerting pressure on the outer face of the neck of the plug.

There are other types of plugs, which solve the problematic exposed in the previous paragraph, which have a joint that is injected directly into the outer perimeter zone from the neck of the cap, in an area adjacent to the outside of the same, being this type of joints of a plastic material injectable For the injection of the joint they have to be performed previously, either externally of the cap neck itself or in inside of it a channel in which the nozzle of plastic injection for the injection of the seal.

In the case where the channel is made in the external part of the neck, there is a first inconvenience given the poor aesthetic appearance offered by the plug, in which it is appreciated externally a channel filled with a constituent material of the seal different from the rest of the cap.

The problem that this type of joints presents is the high pressure, as well as temperature, that the nozzle has plastic injection, so it is produced quite usual rupture of the plug due to the effect of pressure exerted by the plastic injected directly on the channels made in the cap itself, previously described.

Description of the invention

The present invention relates to a plug airtight bottles, whose application is preferably in the field of industry related to the manufacture of bottles for the transport and consumption of liquids by a user, such as during a field trip, who It comprises an external part, which is located outside the bottle to cover when the plug is placed in a position of bottle closure Said outer part may have a hole of mooring that allows the introduction of the user's fingers allowing a better mooring of the cap for the extraction of the same to produce the opening of the bottle.

On the other hand the cap has a neck, configured to enter inside the mouth of the bottle, producing the closure of it, for which the neck of the cap presents a configuration coinciding with that of the mouth of the bottle, such as cylindrical. In addition to the neck of the plug has a hollow configuration, extending from the part external of the stopper, being located in said area an internal bottom of said neck

Likewise, the plug comprises at least one channel which is embedded in the inner bottom of the neck, so that said channel extends from inside the neck to a outer area of said neck. The channel is set to accommodate a plastic gasket that is configured to be injected from an area near the bottom internal extending through the channels to the outside of the neck around it, constituting a Hermetic seal of fast manufacture, that allows to fill with the material injected throughout the internal fund, given the situation of the injection nozzle, preventing the breakage of the cap during its manufacturing.

A variant of embodiment is contemplated as stopper comprising two channels, arranged according to the same address and that are separated by a separation zone located at the same level as the internal fund in a central area of said internal fund, which achieves a pressure distribution optimal during the injection of the hermetic gasket, occurring a bulge in the area where the nozzle of injection.

Finally, the possibility that the entire plug has a single piece configuration, except for the hermetic seal, which is injected over the configuration cap one piece at a later stage, with the consequent saving of costs and security in terms of breakage and loss of elements of the plug.

Thus, according to the described invention, the cap proposed by the invention constitutes an advance in the plugs hitherto used, and fully resolved satisfactory the aforementioned problem, in the line allow quick, simple and safe manufacturing of a plug resistant without risk of breakage during manufacturing, which offers high security given its tightness, preventing an exit unwanted liquid contained in the bottle.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows three views, according to a elevation, a sectioned profile and a plan view from the area bottom of the cap object of the invention, in which it has not been The seal is represented.

Figure 2.- Shows three views like those of the previous figure in which the board has been represented hermetic

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as in one of the possible embodiments of the invention, the cap comprises an external part (1), which can have a mooring hole (2) for a better mooring of the cap with in order to extract it to open the bottle.

On the other hand the cap comprises a neck (3), configured to enter inside the bottle, so which neck (3) has a configuration coinciding with that of the bottle mouth Said neck (3) has a hollow configuration,  extending from the outer part (1) of the cap, standing at said zone an internal bottom (5) of said neck (3).

Likewise, the plug comprises at least one channel (6) embedded in the internal bottom (5), so that said channel (6) extends from inside the neck (3) to an area exterior of said neck (3).

Channel (6) is configured to host a hermetic seal (7) of plastic material, configured to be injected from an area near the inner bottom (5) extending through the channels (6) to the outside of the neck (3) standing around it, so that the entire internal fund (5) is filled with the plastic material of the seal (7), said internal fund (5) constituting the zone of injection.

The possibility is contemplated, as represented in the figures, that the cap comprises two channels (6), arranged according to the same direction and that are separated by a separation zone (4) located on the same level as the bottom internal (5) in a central area of said internal fund (5), producing a bulge (8) in the seal (7) in the area in which the injection nozzle is located.

Finally, the possibility that the cap has a one-piece configuration, except the seal Hermetic (7), which is configured to be injected onto the single piece configuration cap.

In view of this description and game of figures, the expert in the field may understand that the Embodiments of the invention that have been described may be combined in multiple ways within the object of the invention. The invention has been described according to some embodiments. Preferred, but for the person skilled in the art it will be clear that multiple variations can be introduced into said preferred embodiments without exceeding the object of the claimed invention.
