RECEPTACLE AND CLOSURE SYSTEM
A liquid receptacle system comprising: a receptacle comprising a bowl (3) having an upper opening surrounded by a rim, wherein a screw thread is provided on the interior surface of the bowl, substantially adjacent said rim; and a removable closure (6) for sealing the bowl, the closure having a corresponding external screw thread which in use engages with the interior screw thread of the bowl to enclose contents within the bowl.
This invention relates to a receptacle, a receptacle system and closure system.
BACKGROUND OF THE INVENTIONDrinks receptacles come in many different shapes, sizes and styles.
In terms of drinking wine, cocktails or champagne, the receptacle comprises a bowl standing on a stem above a base. The general term ‘stemware’ is sometimes used. This allows the beverage to be held without being warmed by the drinker's hands. The receptacle can be of any shape, although the term ‘bowl’ is used throughout and is intended to cover goblet, cocktail and flute shapes also The receptacle can be of any material, but is typically glass, crystal glass or plastics material.
In certain situations, for example on aircraft or trains, the motion of travel can cause the beverage to be knocked-over or spilled. In aircraft, in particular, turbulence is a common cause of drinks being spilled over passengers.
For stemmed glasses, such as wine or champagne glasses the higher centre of gravity can be a problem insofar as toppling of the glass is more likely.
It is possible to buy a drinks receptacle, typically in the form of a plastic wine glass, which has wine already in the bowl and sealed within the bowl by a foil wrap extending over the top of the bowl. The receptacle is purchased after which the foil lid is peeled off to access the wine. The receptacle is usually thrown away after use. Whilst such receptacles are suitable for non gaseous liquids, such as wine and water, they are not suitable for carrying gaseous drinks such as sparkling wine or Prosecco™.
SUMMARY OF THE INVENTIONA first aspect of the invention provides a liquid receptacle system comprising: a receptacle comprising a bowl having an upper opening surrounded by a rim, wherein a screw thread is provided on the interior surface of the bowl, substantially adjacent said rim; and a removable closure for sealing the bowl, the closure having a corresponding external screw thread which in use engages with the interior screw thread of the bowl to enclose contents within the bowl.
The closure may comprise a wall having upper and lower surfaces, and wherein a means of pressure-release is provided in or on the closure wall.
The pressure-release means may comprise an aperture passing through the closure wall, and a movable part accessible on or from the upper surface to enable a user, in use, to open the aperture.
The movable part may be further configured to be able to re-seal the aperture after opening.
The pressure release means may be a pivotable flap or door located within or over the aperture and arranged to be moved by user force to open the aperture.
The movable part may be initially joined with the closure wall with a region or weakness around at least part of its perimeter to permit its disjoining due to user force.
The pressure-release means may be a plug that is supported above the aperture and is movable up and down to open and close the aperture respectively.
The pressure-release means may be a stopper that fits over the aperture in a press-snap or threaded manner.
The pressure release means may comprise a ring-pull-type element provided within the closure wall, operation of which is effective to open an aperture.
The pressure release means may comprise a lever, button or switch exposed on the upper wall of the closure wall, and movable within a slot, effective to open and close an aperture located elsewhere in the closure wall.
The pressure release means may comprise an aperture within the closure wall which is sealed with a film or foil, breakable by user action.
A lever or similar tool may be attached to the closure wall's upper surface, adjacent the aperture, and is movable to effect breaking of said film or foil.
The closure may be entirely covered by a removable or breakable film or foil.
The film or foil may be adhered or otherwise fixed to the rim of the receptacle, above the closure.
The system may further comprise reinforcing elements on, above or below the film or foil.
The screw threads of the system may be helical, either continuous or broken.
The system may further comprise a resilient pressure seal located around the interface between the receptacle and closure.
The closure may comprise a handle on its upper surface.
The receptacle bowl may be supported by a stem that is movable in relation to the bowl between first and second configurations.
The bowl may comprise a sleeve extending inwardly from the bowl's lower external surface within which the stem is connected and movable selectively between an extended configuration and a collapsed configuration.
A second aspect of the invention provides a drinks receptacle apparatus, comprising:
-
- a drinking glass or cup comprised of a bowl having an internal engagement portion substantially adjacent its upper rim on the internal bowl surface, the opposite, external bowl surface being smooth; and
- a lid having a downwardly extending portion carrying an exterior engagement portion shaped and dimensioned to co-operate with the internal engagement portion of the glass or cup to provide a sealed cover, the lid further having a user-operable pressure release means.
A third aspect of the invention provides a liquid receptacle comprising a bowl connected to a stem, wherein the stem is arranged to be movable relative to the bowl between extended and collapsed configurations, wherein the bowl comprises a sleeve extending inwards from the bowl's lower surface within which sleeve the stem is connected and movable selectively between the configurations, the interior of the sleeve having a groove which comprises an elongate groove having opposite first and second ends, and transverse side grooves at, or in the region of, said first and second ends of the elongate groove providing respective locking positions, the stem comprising a protrusion on its outer surface which is located within the groove and which in use is movable from one of the side grooves into the elongate groove by relative rotation of the bowl to the stem, along the elongate groove, and into the other side groove by relative rotation.
The invention will now be described, by way of non-limiting example, to accompanying drawings, in which:
Embodiments herein describe drinks receptacles having a closure lid to prevent the spillage of liquid held within the bowl of the receptacle. The lid is removable, and in some embodiments is secured to the receptacle by means of a helical screw thread arrangement, with the screw threads being respectively on an outer surface of the lid and the interior surface of the receptacle. This allows the lid to be gradually unscrewed by a user to reduce the chances of liquid being spilled and also to allow the gradual and controlled release of gas, e.g. in the case of carbonated or sparkling drinks. The fact that the engagement means, i.e. the screw threads, are internal to the bowl avoids contact with a user's mouth which might otherwise cause irritation or skin damage. The outer surface of the bowl can therefore be smooth. The closure systems described herein are also found to maintain pressure within the receptacle at altitude, e.g. to keep champagne or other carbonated beverages sparkling.
Referring to
The wine glass 1 comprises a bowl 3 having an opening 4 at the top into which liquid can be poured and drunk from. From a distal end of the bowl 3 protrudes an elongate stem 5 which can be of any cross-sectional shape. A removable lid 6 is connected to the upper rim of the bowl 3 and closes the opening 4. At the distal end of the stem 5 is a base 7 which is horizontal relative to the stem and is used to support the wine glass 1 on a flat surface.
The stem 5 and bowl 3 may be formed from the same material or may be different materials. For example the bowl 3 may be made from plastic and the stem from aluminium.

In addition, the rim 15, 39 and the corresponding underside of the ring 31 are shaped so as to provide further sealing. In this example, the ring underside carries a protrusion 44 that locates within a correspondingly-positioned and shaped indentation.
As will be appreciated, the above-described lid 6 and the associated internal threading on the receptacle provides a closure system that avoids sharp or jagged edges on the exterior of the drinking surface and therefore avoids damage or irritation to the user. This is particularly important if the glass 1, 40 is used in a transport setting, such as on an aircraft or train, where movement is unpredictable. In addition, its combination with the first embodiment, collapsible glass, provides a compact and more stable product.
The threading also permits a gradual, user-controllable opening motion avoiding spillage and allowing gradual release of carbonating gas in such beverages.
Referring now to
In addition to the use of any one of the above-described lids, there can be provided a removable seal which is initially adhered to the rim, either above or below the lid. The seal can be formed of aluminium foil, or similar material.
