Definitions
- the invention relates to a closable pouring cap for a container for drink comprising a housing, a plunger mov ⁇ able in the housing and a pouring opening provided in the housing, while at its bottom side, which is intended for placing on the container, the housing is provided with means for fastening onto the container and a duct is provided which extends from the bottom side of the housing to the pouring opening and which can be sealed by means of the plunger.
- a pouring cap is known from the European patent application EP-A 0 692 432. Said known pouring cap is in particular suitable for soft drink bottles. However, such a cap is less suitable for containers of liquids whose quality deteriorates after the permanent seal necessary for transport and storage has been removed.
- the closable cap according to the invention is characterized in that the means for fastening onto the container comprise a seal made of elastic material through which the duct passes and that a pump is provided connected to the duct for the withdrawal of gas present in the duct.
- An advantage of the pouring cap according to the invention is that immediately after opening, said pouring cap may be placed on the opening of the container respec ⁇ tively the wine bottle, and can be used as required both as pouring means and as sealing means for the container until said container is empty and the cap may be removed to be placed on a next container of perishable drink.
- the pouring cap according to the invention is shaped to the opening of the container which the cap is intended to seal, and that in longitudinal direction the seal comprises one or more flexible collars placed concentrically in relation to the duct.
- the plunger comprises an end plate which fits tightly in the housing, so that when the plunger is in the closed position, the duct is provided with a gas- and liquid-tight seal and a stem coupled to the end plate, which stem extends to outside the housing and is provided with a control knob. This facilitates the use of the pouring cap. It is preferable that the plunger can be fixed, when it is in the position in which it closes off the duct. This achieves a true seal and avoids that with careless handling an unintentional gas load is put on the liquid in the container.
- a simple manner for fixing the plunger in the clos ⁇ ing position may, according to the invention, be achieved by providing the end plate of the plunger at least over a portion of its circumference, and the housing at least over a portion of its inner wall, with thread suitable for interacting to fix the plunger in the closed position.
- the pump of the pouring cap is formed such that the stem of the plunger is hollow, the stem comprises a piston which is movable in the longitudinal direction of the stem, and the end plate of the plunger is provided with a non-return valve. It is clear that, especially when the plunger is fixed in its closed position, the pump may be operated by moving the piston up and down in the fixed stem of the plunger without any risk of displacing the plunger from the closing position.
- the inner wall of the plunger's stem and the rod of the piston thus define a gas discharge duct allowing the removal of gas withdrawn from the duct. Discharge into the atmosphere takes place via this gas discharge duct.
- Proper working of the pump is preferably obtained by providing the piston with an O-ring sealing against the inner wall of the plunger, which O-ring, when pressure above a predetermined value is exerted on the piston, will at least over a portion of its circumference deviate from said inner wall.
- the drawing comprises one Figure showing a side view of the closable pouring cap according to the invention in cross-section.
- the pouring cap comprises a housing 1, and a plunger 2 movable in the housing 1 and a pouring opening 13 provided in the housing 1, and a seal 5 made of elastic material, preferably rubber, at the side of the housing 1 that is to be placed on a sealable container.
- the housing 1 comprises a duct 14, while in the drawing the plunger 2 is shown in the position whereby the connection from the duct 14 to the pouring opening 13 is sealed.
- the seal 5 is shaped to the opening of the container to be sealed, in this case a bottle neck.
- the seal 5 is provided with one or more flexible, in relation to the duct 14 concentrically positioned collars 15 providing a gas-tight fit of the pouring cap on the opening of the container.
- the plunger 2 comprises an end plate 16 which, when the plunger 2 is in the closed position, provides a gas- and liquid-tight seal to the duct 14.
- the plunger 2 also possesses a stem 17 linked to the end plate 16 extending to outside the housing 1 where it is provided with a control knob 9.
- the pouring cap is preferably embodied such that the plunger 1 can be fixed, when it is in the position in which it seals the duct.
- the endplate 16 of the plunger 2 may, at least over a portion of its circumference, and the housing 1 may, at least over a portion of its inner wall, be provided with thread suitable for interaction to fix the plunger 2 in the closed position. This is not shown in the Figure.
- the Figure does show that the circumference of the endplate 16 and the inner wall of the housing 1 are provided with rubber rings 6 which together, in the end position of the end plate 16 near the seal 5, provide the gas- and liquid-tight seal of the duct 14.
- the stem 17 of the plunger 2 is hollow and the stem 17 comprises a piston 12 which is movable in the longitudinal direction of the stem 17, and the end plate 16 of the plunger 2 is provided with a non-return valve 3.
- a rod 4 is coupled which extends to outside the housing 1 through the control knob 9 of the plunger 2.
- a piston control knob 10 is pro ⁇ vided.
- the inner wall of the stem 17 of the plunger 2 and the rod 4 of the piston 12 thus define a gas discharge duct 11.
- the piston 12 is provided with an O-ring 12 to seal against the inner wall of the plunger which O-ring 12, when pressure above a predetermined value is exerted on the piston 12, will at least over a portion of its circumference deviate from said inner wall of the stem 17. This allows compressed air in chamber 18, which is defined by the end plate 16, the inner wall of the stem 17 and the piston 12, to escape into the atmosphere via the gas discharge duct 11.
- the housing is also provided with a ventiduct 19 which, by means of the plunger 2, can be sealed simultaneously with the pouring opening 13.
- the pouring cap may be used as follows.
- the plunger 2 After pla ⁇ cing the part of the pouring cap where the seal 5 is located on the bottle neck, the plunger 2 is placed in the highest position by means of the control knob 9; liquid is now able to flow freely via the duct 14 to the pouring opening 13 so that it may be poured from the bottle. Controlled pouring is ensured through de-aeration via ventiduct 19 provided in the wall opposite the pouring opening 13. If the remainder of the liquid is to be stored in the bottle, the plunger 2 can be pushed completely into the housing 1 by means of the control a knob whereby said plunger will eventually reach the closed position and the flexible rings 6 on the end plate 16 and the inner wall of the housing 1 ensure that the duct 14 is sealed completely gas- and liquid-tight.
- the pouring cap may be embodied such that the plunger 2 is rotatable and that both the end plate 16 and the inner wall of the housing 1 are provided with thread which engage to ensure that the plunger 2 in the closed position is fixed. This is done by turning the control knob 9 while the plunger 2 is in the closed position. In this position the piston control knob 10 provided on top of the control knob 9 can be moved up and down so that gas which is present in the bottle and disperses up to the part of the duct 14 extending through the seal 5, can be withdrawn. As a consequence of pulling the piston control knob 10 up, the piston 12 is simultaneously pulled up thereby enlarging the chamber 18 defined by the endplate 16, the inner wall of the stem 17 of the plunger 2 and the piston.
