Description

EXXIVEAU BOUCSGE DEVICE WITH MULTIPLE EWCTIES
FOR BOTTLES AND OTHER RCIPIEETS
The present invention relates generally to a closure device ensuring the possibility for the user to ensure a homogeneous flow of the liquid contained in the container thus blocked as well as the sealing of the closure.

In fact, this closure device is more particularly intended for bottles with closure by fitting or by screwing on which the liquid device, according to the invention, is mounted and which puts the liquid contained in this bottle away from atmospheric contamination. .

This objective is more specifically important for the distribution of food or pharmaceutical products which must, during their use, remain protected from the entry of dust, contamination agents and especially of bacterial germs as far as possible.

Another object of the invention is to ensure a regular distribution of the liquid as and when used by means of a hollow nozzle distributing a determined and constant volume of liquid whatever the level of filling of the container;
Finally, another objective of the invention lies in obtaining a safety closure - of the closure device according to the invention, making the opening of the bottle made if not impossible, at least very difficult for an untrained manipulator. or for a child.

We already knew, in fact, safety devices mounted on bottles or various containers using, in general, the principle of a stopper having a skirt and an internal thread in this skirt.

In these types of device, part of the internal thread of the closure means is cut and is carried by the ring, and when the stopper is in place on a bottle, it suffices to push the ring down into a position at below the last thread of the container thread, the connecting parts, in this position, being partially straightened. When trying to unscrew this plug, the thread part of the ring is blocked with the last thread of the container thread and pockets the removal of the plug.

This device does not offer all the guarantees of security, in the sense that if one tries to force the cap by unscrewing it, the connecting parts can either break, in which case no obstacle is more opposed to unscrewing the plug, or not break and risk driving the ring in rotation with it by forcing it to cross the thread of the thread of the neck of the container which separates it from the skirt. In this case, there is no longer any obstacle to opening the bottle.

 Finally, it should be noted that this device causes complications with regard to the use of automatic machines for fitting the caps, to push the ring below the last thread of the container thread after the cap has been screwed on.

We also already know hermetic closure devices for containers which are characterized by the fact that the mouth of the container comprises a helical relief on which is applied by pressure, a laminar cover constituted by an upper panel, a peripheral skirt which is connected to the panel by means of a curved section which forms a groove around said panel, and a compressible plastic junction which fills said channel and extends downwards on the internal wall of the skirt, to adapt, when the lid is applied by pressure on the mouth of the container, to the helical relief of this mouth so that is engraved in the plastic, the groove corresponding to said relief, forming between the two, a thread making it possible to remove the threaded cover and replace it, if desired, during the time the container contains a product.

The object of the invention is to remedy the drawbacks of the plugs and of the closure devices mentioned above and it has for its object, for this purpose, a plugging device with several functions which simultaneously performs the function of putting the container by opening a shutter end, the function of distributing a determined volume of liquid at each use and the protective function of the product contained in the container either against an untimely opening, or against -vis the risks of pollution.

The invention therefore relates to a closure device with several functions for bottles or other flexible containers in which the clamping means constituted by a system of notches or a thread carried on the neck of a bottle or container cooperates with the notch system or the threading of a nozzle conforming to the shape of the upper external portion of the bottle or container, and comprising at its upper end, a hollow pin of determined section open at its two ends which has a tapered body at its internal lower part capable of perforating the upper external portion of the bottle or container and said pin carries, on the external face, a second thread or notch system on which a symmetrical system of notches, threaded or not, is clamped or fitted together plugging means of tubular form mounted on the end piece and fitted or screwed thereon.

More precisely, the device according to the invention comprises
- A tip snapped on or screwed onto the bottle or container, the pin of which punctures the upper end of the neck and cover it as it is screwed or fitted onto said tip of the bottle.

 - And a sleeve overcoming the screwed or nested end to seal it and mounted tightly by means of a thread or a system of notches carried by the endpiece.

One of the important elements of this device is therefore the nozzle fitted with a piercing pin by its internal end, the tightening of which on the notch system or on the thread carried by the neck of the bottle or container allows its introduction. This spike open at its two ends functions like a capillary dropper and ensures the distribution of the liquid contained in the bottle or container under a determined volume, whatever the section of the perforation, the viscosity of the liquid or the level of filling of the bottle. .

The bottle can be made of rigid material, preferably glass or plastic or a flexible material, and in particular polyethylene or polypropylene. I1 can be closed at the start either by a crimped aluminum film or any other tearable material, or by a crimped or nested molded tip possibly having at its tapered end, a zone of least resistance ensuring its perforation by the pin.

The mouthpiece follows the shape of the base of the neck of the bottle and covers its upper end which can be flat, spherical, frusto-conical or ovoid. It is tightened on the base of the bottle neck by the notch system or by a thread.

The perforating pin consists of a tubular part made of hard material such as rigid plastic or glass, fixed on the end piece in the center of the upper portion, and it has an opening to the external part, of circular shape and an opening to the internal part of tapered shape. This tube is hollow and is used for the flow of the liquid contained in the bottle.

The upper sleeve is fitted or screwed onto the notch system or the thread carried by the end piece, in its upper part and prevents any outflow of liquid or any entry of contaminant. It can be snapped on or screwed on by a simple thread or by a system of notches or by a ratchet thread where the thread cooperates with a toothing in opposite directions connected to the end piece by oblique connecting parts. Therefore, when one seeks to unscrew or dislodge the upper sleeve, the connecting parts inclined in the opposite direction of unscrewing or disengaging act in this direction as links articulated by their ends and, therefore, force the internal toothing of the sleeve to remain in engagement with that of the nozzle.

Other characteristics and advantages of the invention will appear during the description which follows, with reference to the appended drawings, given solely by way of example of a particular embodiment and in which - FIG. I is a view exploded view of the embodiment of the closure device according to the invention - Figure 2 is a sectional view of the nozzle and of the sleeve mounted tight on said nozzle.

In FIG. 2, we see the neck (l) of the bottle appearing carrying at its base a system of notches (2), terminated at its upper part by an ovoid perforable end (3) and having at its base a circular rim (14 ) on which the end piece (4) abuts.

The tip (4) is subject by its system of grooves (5) on the notches of the bottle (2). it follows the shape of the neck of the bottle, and ends in a flat surmounted by a warped part (6) having a thread (11) at its lower part which is crossed by the perforating pin (7) open at its two ends . The external end (8) of the pin is wider than the internal end (9) of said pin which is terminated by a tapered nozzle (10). The external part of the spike is approximately spherocylindrical and ends in a flat intended to ensure the formation of drops of a constant volume and a homogeneous flow. The length of the spike is between 1 and 10 mu and its section ranges from 0.1 to 2 mm. The spike plunges into the neck of the bottle over a length ranging from 1 to 5 mm.

The sleeve (12) with a length of 10 to 20 mm is approximately tubular in shape, of section slightly narrowed at the top relative to the base body. It has at its upper internal part, a triangular section indentation (13) which fits into the external end (8) of the pin. The sleeve cooperates by its thread (13) with the thread (11) of the ogival portion of the nozzle. It can carry on its external face all types of gripping or tightening means, such as grooves, ribs, ridges, pins, dots and others.

The thread of the two threads (13 and 11) can be in the same direction or on the contrary, in the opposite direction.

Figure 1 is a side view showing the tip (4) screwed onto the bottle (1) or the container (1) to perforate the upper portion (3) (not shown) and the sealed upper sleeve (12) ensuring airtightness and inviolability.

The bottle is preferably made of flexible material such as polyethylene or polypropylene, so as to be able, by compression, to ensure if necessary a certain propulsion of the liquid contained in the bottle.

The bottle (1) can also be made of rigid material such as glass or an acrylic polymer, but in any case, the end piece (4) will in this case be made of flexible material.

The device according to the invention can be used, in particular, as a dispensing device for a container intended for ocular, nasal or ear preparations, for therapeutic use. For eye preparations, the liquid or suspension is run off by light pressure, drop by drop. For more viscous nasal or ear preparations, it may be preferable to carry out the flow of the liquid under a slightly higher pressure, especially if the liquid is less fluid.

Nevertheless, the flow by exerting a slight pressure has the advantage of ensuring a constant distribution and an easier unitary distribution since the flow is done drop by drop.

For use, the upper sleeve is removed and the flow takes place by pressure.

After use, the sleeve is put back in place and fitted or screwed onto the notch system or on the thread to guarantee its hermetic character.

The nozzle (4) and the sleeve (12) can be previously sterilized and kept in a sterile packaging. The bottle or container (1) can be filled in a sterile manner or sterilized after filling so that, when inserting the closure device according to the invention, the sterility of the preparation can be preserved as much as possible. .
