Abstract

A cap 10 for fitting over the mouth of a bottle 20 has a closable outlet valve 18 terminating in a spigot. In use the spigot is connected to a source of suction, the pressure within the bottle 20 reduced and the valve closed, whereby the storage life of the contents is enhanced. As shown, the closure is a cap having a tapered or stepped internal surface so that it may fit a range of bottle- neck sizes. Alternatively the closure may be a plug, expandable or otherwise. <IMAGE>

Description

SPECIFICATION Bottle closures This invention relates to bottle closures. It is often desirable to store the contents or the partly-used contents of a bottle under a partial vacuum in order to reduce the rate of oxidation of the contents and the risk of contamination by bacteria or other air-borne micro-organisms. - Common domestic substances which benefit from storage under partial vacuum in this way are non-sparkling wine, paint, dairy milk and baby's milk made up in a feeding bottle.
According to the present invention there is provided a bottle closure for sealing and evacuating a bottle, the closure comprising a sealing member of flexible and preferably slightly resilient, material, an outlet valve, and a connector to a source of suction. Although the sealing member may have the form of a plug for insertion into the mouth of the bottle, with or without means to expand it radially, it is preferred that the sealing member should have the form of a cap to fit over the top of the bottle.
The internal surface of the cap may be tapered or stepped to accommodate a range of different sizes of top and may also have internal ridges to enhance the engagement of the cap with the top of the bottle.
The outlet valve may be of any convenient type but is preferably postively closable, e.g.
by rotation.
In use, the cap is simply placed over the top of the bottle whose contents it is desired to preserve; the connector connected to a source of suction, most conveniently, a venturi-type water vacuum pump; the pump operated to withdraw air from the bottle; the valve closed; and the connector subsequently removed. In suitable cases the bottle may be refrigerated in order further to preverse its contents.
An embodiment of the invention will now be described, by way of example, with reference to the accompanying drawings in which Figure l is a perspective view of a bottle cap according to the present invention; and Figures 2 and 3 are similar views showing the cap fitted to a wine bottle and milk bottle, respectively.
A cap 10 as shown in the drawings comprises a body 12 moulded from soft, pliable plastics material, e.g, a PVC dipping, and having a generally frusto-conical wall portion 14 terminating in a domed top portion 16.
An outlet valve 18 of known type which is closable by a screw action is secured in a central aperture in the top portion 1 6 and terminates in a spigot 20 for connection to a flexible nose (not shown) to a venturi-type water vacuum pump.
Figs. 2 and 3 show the-cap 10 fitted to a partly full wine bottle 20 and milk bottle 22, respectively. After fitting the cap 10 to the bottle 20 or 22 the air above the liquid contents is removed by the pump and the outlet valve 1 8 closed. The storage life of the contents is thus much enhanced.
1. A bottle closure for sealing and evacuating a bottle, the closure comprising a sealing member of flexible material, an outlet valve and connecting means for connecting the closure to a source of suction.
2. A closure as claimed in Claim 1 and having the form of a cap for fitting over the mouth of a bottle.
3. A closure as claimed in Claim 2, in which the internal surface of the cap is tapered or stepped to accommodate bottle tops of different sizes.
4. A closure as claimed in Claim 1 and having the form of a plug.
5. A closure as claimed in Claim 4 and additionally comprising expansion means to expand the plug radially.
6. A closure as claimed in any preceding claim in which the sealing member is of slightly resilient material.
7. A closure as claimed in any preceding claim in which the outlet valve is positively closable.
8. A closure- as claimed in Claim 1 and substantially as herein described.
9. A bottle closure substantially as herein described with reference to the accompanying drawings.
10. A bottle closure as claimed in any preceding claim when fitted to a bottle.
11. The features as herein disclosed, or their equivalents, in any novel selection.
