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 in the figure includes two separate injection-molded parts of plastic material (for example polypropylene), namely the connection piece 2 and the drain 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. The tubular portion 10 is integrated with the inner edge of the flange 8. The axis of the tubular portion 10 is parallel to the axis of the annular portion 6, and the tubular portion 10 is open at the end close to the annular portion 6, and at the end close to the annular portion 6 The opposite end is closed. Thereby, the inside of the tubular portion 10 communicates with the inlet space defined by the annular portion 6. In use, a liquid flow opening 12 is formed on the pipe wall at the lowermost part of the tubular portion 10. A gas flow opening 14 is also formed on the pipe wall of the tubular portion 10 at a position diametrically opposite...

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 annularspace. 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 a resealable liquid dispenser. In other words, it relates to a device having the properties of a tap which can be selectively opened to dispense liquid in a container, and the valve can be closed again subsequently, And will form a reliable seal to prevent further dispensing of the liquid until the liquid needs to be ejected. More specifically, the present invention relates to a liquid dispenser including an outer tube and an inner tube, the outer tube having a discharge port formed in a side wall of the outer tube, and the inner tube is at least partially accommodated in The outer tube defines an annular space with the outer tube, and the outer tube is connected in a sealed manner with an integral connection member (one-piece connection member) defining an inlet space, and the integral connection member is used for connection Liquid container, one end of the inner tube is closed, and the outer tube and the inner tube are ...
