Therefore, the shaving cream can be easily supplied to the blade assembly 3 only by operating the pushing mechanism 30 without operating the storage container 10 at all.

In the supply state P of the pushing mechanism 30, as shown in FIG. 2 (a), the supply valve body 26 is in the open position, the shaving cream storage chamber 27 communicates with the extrusion chamber 17, and the discharge valve body 19 is in the closed position, and the pushing chamber 17 is shut off from the blade assembly 3. Therefore, the shaving cream can be reliably supplied from the storage chamber 27 to the extrusion chamber 17. However, in the present embodiment, since the supply valve element 26 is in a loosely fitted state in the valve chamber 21,
There may be a case where the valve is not completely opened or closed with respect to the valve hole 24, but in any case, the flow of the shaving cream is regulated, so that there is no functional problem.

In the discharge state Q of the push-out mechanism 30, as shown in FIG. 3 (a), the supply valve 26 is in the closed position and the shaving cream storage chamber 27 is shut off from the push-out chamber 17, and When the discharge valve body 19 is in the open position, the extrusion chamber 17 communicates with the blade body assembly 3. Therefore, the shaving cream can be reliably supplied from the extrusion chamber 17 to the blade assembly 3. However, in the present embodiment, since the discharge valve element 19 is in a loosely fitted state in the valve chamber 15, the discharge valve element 19 may not be completely opened or closed with respect to the valve hole 16. There is no functional problem because the flow of traffic is regulated.

* Although not shown, when a supply valve or the like is provided in the connection port of the shaving cream storage container,
The internal structure of the connection port becomes complicated, and the manufacturing cost of the shaving cream storage container increases. In addition, every time the shaving cream storage container is replaced, it is necessary to simultaneously replace a supply valve body and the like having a normal function, which is wasteful in manufacturing costs.

In this embodiment, a valve chamber 21 and a valve hole 24 are provided outside the connection port 29 of the shaving cream storage container 10 as a supply passage.
The supply valve element 26 was inserted into the valve. Therefore, this connection port 2
9 is simplified, and the manufacturing cost of the shaving cream storage container 10 is reduced. Further, the shaving cream storage container 10 can be replaced irrespective of the supply valve element 26 having a normal function, which is advantageous in manufacturing cost.
