A CONTAINER CLOSUREA CONTAINER CLOSURE
The invention is directed to a container closure suited for use as a closable opening for a container. The invention is also directed to a container provided with this container closure.The invention is directed to a container closure suitable for use as a closable opening for a container. The invention is also directed to a container provided with this container closure.
US4375864 describes a container closure having a body provided with a channel which connects the exterior of the container with the interior of the container. The channel is closed by a plug which seals the opening through a first snap fitting. When an external member, such as a suction tube of a pump, is inserted into the channel from the exterior of the container it will engage with the plug by means of a second snap fitting and disengage the first snap fitting. When the external member is retracted from the container closure the second snap fitting disengages and the first snap fitting engages. A disadvantage of such a closure is that it is very sensitive to material fatigue. With this closure it is well possible that after multiple use the external member pushes the plug into the container without engaging with the plug.US4375864 describes a container closure having a body provided with a channel which connects the exterior of the container with the interior of the container.

A disadvantage of such a closure is that it is very sensitive to material fatigue. With this closure it is well possible that after multiple use the external member pushes the plug into the container without engaging with the plug.
This disadvantage is overcome with the container closure of EP1233228. EP1233228 describes a container closure provided with a female part and a plug. The female part has a body containing an axial bore which extends from an insert opening for a male part through the body and having a seat for the plug at its opposite end. The plug serves to close off the bore. The plug is connected to the female member by a flexible ring wall which avoids that the plug can be lost in the container as with the closure of US4375864. The flexible ring wall ensures that the plug rests under pre-stress on the bore such to close off the bore. When a male part, such a suction tube of a pump, is inserted into the female part from the exterior of the container the tip of the male part can axially move the plug from its seat and so create a fluid passage. When the male part is withdrawn the plug will return to its seat because of the flexible ring. In this design there is less danger that the plug is lost in the container as with the closure of US4375864.This disadvantage is overcome with the container closure or EP1233228.

A disadvantage of the container closure according to EP1233228 is that the female part is sensitive to mechanical failure. This may be explained by the fact that such female members have to be welded into plastic bags. The flexible ring wall of the female member may then be damaged.A disadvantage of the container closure according to EP1233228 is that the female part is sensitive to mechanical failure.

Also shown is a spray pump 22 as disclosed in US5732853 having a suction tube 21 which is only partly inserted into second channel 8. The container closure as shown is in its first position wherein the cap 9 and the second female member 5 provide a fluid seal enclosing the interior of the container and the exterior of the container. The snap connection is achieved between the radially outer side 17 of the open end 11 of the second female member and the rim 13 of the cap 9 and between the radially inner side 22 of the open end 11 and the radially outer side 23 of pin 14.Figure 2 shows the assembled container closure making use of the parts shown in Figure 1.

The container closure as shown is in its first position 9 and the second female member 5 provide a fluid seal enclosing the interior of the container and the exterior of the container. The snap connection is achieved between the radially outer side 17 or the open end 11 or the second female member and the rim 13 or the cap 9 and between the radially inner side 22 or the open end 11 and the radially outer side 23 or pin 14 .
In Figure 3 the suction tube 21, as the external male member, is fully inserted into the second channel 8. As a result of this insertion of suction tube 21 pin 14 and cap 9 is axially displaced in the direction of the container because suction tube 21 axially pushes pin 14 towards the container. The base ring 15 is fixed into position by assembly of the second female member 5 and cap 9 into the first channel 7. Because of this fixation of ring 15 resilient member 10 will try to force cap 9 back on its seat on second female member 5. As long as suction tube 21 is in the position shown in this Figure 2 no such displacement will occur. A flow path is created which runs via the interior of the suction tube 21, along an annular space between pin 14 and the interior of the second channel 8, a space between the circular head 12 and rim 13 and the end of the second female member 5 and the space between the cap 9 and the interior of the 7 of the first channel.In Figure 3 the suction tube 21, as the external male member, is fully inserted into the second channel 8.
