Problems solved by technology

A disadvantage of this known container is that the valve seat of the connecting member is susceptible to damage when the valve is fixed to the connecting member and when the valve is moved up and down relative to the connecting member
Another disadvantage is that radial openings in the valve have an adverse effect on the accuracy of the valve shape, with the result that the seal is no longer reliable

Embodiment Construction

[0024] figure 1 A first embodiment of a container according to the invention is illustrated. This container 1 comprises a wall formed by two sheets 2 which are sealed to each other along a seam 8 . This wall defines a reservoir 3 containing fluid. The container 1 also includes a sealing device 4 which is connected to the foil 2 by a weld 9 . The sealing device 4 comprises a connecting element 10 which has a valve seat 11 and a channel 12 leading to the storage chamber. The sealing device 4 comprises a valve 20, which is formed separately from the connecting member 10, relative to the connecting member 10, from an open position (see FIG. 3 ) in which the passage 12 is open, which is movable in a first direction 5 parallel to the passage 12, to Closed position, in which the valve 20 cooperates with the valve seat 11 and the passage 12 is closed (see Figure 5 ).

Abstract

A container has a wall which defines a space for holding a fluid and a sealing device (4) connected to the wall. The sealing device (4) comprises a coupling member (10) having a seat (11) and a channel (12) which gives access to the space. The sealing device (4) further comprises a valve (20), which has been formed separately from the coupling member and which is movable with respect to the coupling member in a first direction (5) parallel to the channel from an open position, in which the channel is open, to a closed position, in which the valve cooperates with the seat and the channel is closed. The sealing device (4) has two arms (13, 14) which position the valve (20) in its open position and which support the valve (20) in the first direction (5). The arms (13, 14) are separated from the seat (11) and in its open position while the valve (20) is clear of the seat (11). In this way a reliable sealing is achieved.

Description

technical field [0001] The invention relates to a container as defined in the preamble of claim 1 . [0002] The invention also relates to a closure for such a container. Background technique [0003] Such a container and such a closure are known from US patent 3,768,501. The known container comprises a bulb and sealing means secured to the neck of the bulb. The sealing means comprises a connecting member having a channel and a valve which is slidable within the channel from an open position to a closed position. This valve is tubular and closed at a first end facing the inside of the bulb and open at a second end remote from the first end. The tubular valve also has a radial opening in the tubular wall. The connecting member is connected to the neck of the tube and has a valve seat which is a snug fit around the valve in which the valve is slidable. In the closed position, the valve seat and the valve form a seal of the tubular casing, since the radial opening in the v...
