Problems solved by technology
However, the liquid dispensers disclosed in the prior art documents referred to above are unsuitable for this purpose, since they do not allow gas to displace the dispensed liquid volume
Since the inner tube is only in sliding sealing contact with the connection part over a small part of the length of the inner tube, in each case existing distributors may also be insufficiently sealed.

Embodiment Construction
[0012] The dispenser as shown comprises two separate injection molded parts of plastics material, eg polypropylene, namely the connection piece 2 and the discharge piece 4 . The connecting piece 2 includes an annular cylindrical portion 6 and an annular flange 8 integral with one end of the annular cylindrical portion 6 . A tubular part 10 is integral with the inner edge of the flange 8, the axis of the tubular part 10 is parallel to the axis of the annular part 6, and the tubular part 10 is open at the end close to the annular part 6, and at the end close to the annular part 6 The opposite ends are closed. The interior of the tubular portion 10 thus communicates with the inlet space defined by the annular portion 6 . A liquid flow opening 12 is formed in the tube wall of the lowermost part of the tubular part 10 in use. A gas flow opening 14 is also formed on the tube wall of the tubular portion 10 at a position diametrically opposite to the liquid flow opening 12 . A shor...

A liquid dispenser of resealable type includes an outer tube (22) with a discharge opening (28) formed in it and an inner tube (20), which is partially accommodated within the outer tube (22) and defines with it an annular space. The outer tube is connected in a sealed manner to a one-piece connection member (2), which defines an inlet space, for connection to a liquid container. One end of the inner tube (20) is closed and the outer tube (22) is integrally connected to the inner tube (20) by a flexible integral web (24), whose width in the radial direction is greater than that of the annular space. A liquid flow opening (30) is formed in the wall of the inner tube (20) and the inner tube (20) is movable longitudinally within the outer tube (22) between an open position, in which the inlet space communicates with the discharge opening (28), and a closed position, in which the inlet space does not communicate with the discharge opening (28). The connection member (2) includes an integral tubular portion (10), of which one end is closed and the other end communicates with the inlet space. A liquid flow opening (12) is formed in the tubular portion (10) and the outer surface of the tubular portion (10) is in sliding sealed contact with the inner surface of the inner tube (20), whereby the two flow openings (12, 30) are at least partially in registry in the open position and are out of registry in the closed position.
Description
technical field [0001] The present invention relates to resealable liquid dispensers, in other words to devices having the properties of a tap which can be selectively opened to dispense liquid in a container and which can subsequently be closed again, and will form a positive seal preventing further dispensing of liquid until it is required to eject the liquid. More specifically, the present invention relates to a liquid dispenser comprising an outer tube having a discharge opening formed in a side wall of the outer tube and an inner tube at least partially housed in a In the outer tube, and defining an annular space with the outer tube, the outer tube is connected in a sealed manner with a one-piece connection member (one-piece connection member) defining an inlet space for connecting In a liquid container, one end of the inner tube is closed, and the outer tube and the inner tube are integrally connected through a flexible integral web (flexible integral web), and the widt...
