Abstract

The invention relates to the field of dispenser caps for liquids in bottles, and provides an elastic sleeve (2) which surrounds a bottle neck and exhibits a fluid-tight interspace (6) filled with liquid, a pressure action exerted by gripping the bottle neck being such as to raise a closure element (8 and 9) activated in contrast to a spring (13) action.

Description

A Dispenser Cap for Liquids in Bottles
Description.
The invention relates to a dispenser cap for liquids in bottles.
The prior art teaches caps which overcome the problem of automatically closing a bottle once a liquid contained inside it has been poured.
Known caps are all provided with a lever pivoted to a truncoconical element having a through hole, which element is partially inserted in the bottle neck.
One arm of the lever is operated on by the user's hand when the liquid is poured, such as to rotate the lever which, at an end of its other arm bears a circular closure element with a seal that stops up the aperture of the through hole as soon as the activating lever is released, thanks to a spring activation thereof.
Dispenser caps of known type have been shown to be scarsely practical inasmuch as considerable pressure is needed to keep the circular closure element open during the whole pouring procedure, and also inasmuch as the bottle has to be gripped in a certain way in order for the user to operate the lever.
The main aim of the present invention is to facilitate the pouring operation and guarantee the automatic closure of the bottle itself once the lever is released, without having to recur to screwing operations or to provisional capping. This and other characteristics besides will be better evidenced in the following description, of a preferred embodiment illustrated by way of a non-limiting example in the accompanying drawings, in which:
- figure 1 shows a longitudinal section of the dispenser cap applied to the neck of a bottle and in an open position;
figure 2 shows the dispenser cap in a closed position.
With reference to the figures, 1 denotes the neck of a bottle which is surrounded by a sleeve indicated in its entirety by 2. The sleeve 2 comprises a first portion 3 in elastic material substantially formed by two walls 5 and 4 , which are coaxial and distanced one from the other such as to form a fluid-tight interspace 6 into which a liquid or gas is injected.
The sleeve exhibits a second portion 7, which in the case illustrated in figure 1 is a prolongation of the first portion 3, which projects above the bottle neck and which is bellows-shaped with a hollow internal space communicating with the fluid-tight interspace 6.
A seal ring 10 is installed inside the second portion 7, which seal ring 10 rests on the bottle mouth and exhibits a conical seating 11 on which a sphere 9 or other closure element rests.
The sphere is kept pressed against the seating 11 by a guide element 8 provided with holes 12 for the passage of the liquid, which guide element 8 is kept pressed downwards by a spring 13 inserted between the folds of the bellows.
The second portion 7 is surrounded by a telescopic element 14 having the function of protecting and guiding the bellows or extendable portion of the device.
The above-described device enables a security guarantee seal to be applied to the bottle, and can therefore be sold directly applied on a bottle containing a liquid.
The device functions as follows: when a user grips the bottle by the neck, necessarily pressure is automatically exerted thereon and hence a pressure on the first portion 3 of the sleeve 2 results. The internal fluid in the sleeve, preferably a liquid, will thus be forced towards the ho l l ow i nterna l space of the second port i on 7 which is in communication with the fluid-tight interspace 6 of the first portion 3, causing the guide element 8 to rise and to contrast with the spring 13; consequently the sphere 9 frees the seating 11 of the seal 10.
The liquid contained in the bottle can now be poured. By releasing the bottle, and therefore not exerting pressure on the first portion 3, the spring will force the sphere or other closure element, for example a conical element, into the special seating 11.
In a further embodiment, entering into the same field of protection of the following claims, the second portion 7 might be directly realized by a telescopic element activated by direct pressure exerted on the first portion 3, there being no bellows element included.

Claims

Cl aims .
1. A dispenser cap for liquids in bottles, characterised in that it comprises an elastic sleeve (2) composed of a first portion (3) externally surrounding a bottle neck over at least a gripping area of the bottle, said first portion (3) being formed by two concentric walls {U and 5) made of elastic material and mutually distanced such as to form therebetween a fluid-tight interspace (6) which is filled with a fluid, and a second portion (7) projecting superiorly from the bottle neck, said second portion (7) being extendable coaxially to the bottle neck to raise a closure element (8) and (9) which is mechanically connected to the second portion (7); an extension of the second portion (7) being caused by a pressure of a hand exerted on the first portion (3) in gripping the bottle neck.
2. A dispenser cap as in claim 1, characterised in that the fluid-tight interspace (6) is filled with a liquid.
3. A dispenser cap as in claim 1, characterised in that a seal ring (10) is housed in the second portion (7), which seal ring (10) exhibits a seating (11) for a closure element (9) on which a guide element (8) acts subject to an elastic action of a spring (13), said spring (13) action being in contrast with an extension of the second portion (7) caused by a pressure of a user's hand on the first portion (3) surrounding the bottle neck.
4. A dispenser cap as in claim 1, characterised in that the second portion (7) is bellows-shaped and is extendable in accordance with a longitudinal axial direction of the bottle and affords a hollow internal space which communicates with the fluid- tight interspace (6) of the first portion (3).
5. A dispenser cap as in claim 1, characterised in that the second portion (7) is constituted by a telescopic metallic element connected to one of the concentric walls (5, 4) of the first portion (3) such that pressure on the first portion (3) causes extension and rising of the telescopic element.
6. A dispenser cap as in claim 1, characterised in that it comprises a telescopic element (14) which is coaxial to the sleeve (2) and which protects and guides the bellows-shaped second portion (7).
