Abstract

PROBLEM TO BE SOLVED: To surely supply shaving cream into a storage chamber into a push-out chamber, and to surely supply the cream to a blade assembly from the push-out chamber by a required quantity. SOLUTION: A shaving cream storage unit 10 is covered with a tube cover, and a push-out chamber 17 incorporates a push-out mechanism 30 which can increase the internal volume of the push-out chamber 17 into a supply condition P and can decrease the same into a discharge condition. In the supply condition P, a supply valve element 29 takes its opening position so that the shaving cream storage chamber 20 is communicated with the push-out mechanism 17 while a discharge valve element 19 takes a close position so that the push-out chamber 17 is isolated from a blade assembly 3. In the discharge condition, the supply valve element 29 takes its close position so that the shaving cream storage chamber 20 is isolated from the push-out chamber 17 while the discharge valve element 19 takes its opening position so that the push-out chamber 17 is communicated with the blade assembly.

The pushing mechanism 30 incorporated in the supply / discharge cylinder 5 is configured as follows. The push-out chamber 17 in the supply / discharge cylinder 5 extends in the left-right direction.
2 is inserted so as to be movable in the left-right direction. Shafts 33 and 34 are fitted to the central portions of the pistons 31 and 32, respectively. A guide hole 33a is formed at the inner end of the shaft 33 of the first piston 31, and a guide shaft 34a is protruded from the inner end of the shaft 34 of the second piston 32. Are movably inserted in the guide hole 33a in the left-right direction. The outer end of the shaft 33 of the first piston 31 and the shaft 34 of the second piston 32
Are exposed from both left and right sides of the supply / discharge cylinder 5, and operation portions 35 and 36 are attached to the outer ends thereof. In the extrusion chamber 17, the first piston 31 and the second piston 3
2 between the compression coil spring 37 and their shafts 33, 3
4 is wound around the outer periphery of the inner end. The first piston 31 and the second piston 32 are moved away from each other in the extrusion chamber 17 by the bias of the compression coil spring 37 so as to be in the supply state P (see FIG. 2). The two operation units 35, 3
By pressing 6, the first piston 31 and the second piston 32
Against the elastic force of the compression coil spring 37, the extrusion chamber 1
7 and move closer to each other so as to be in a discharge state Q (see FIG. 3).

(Regarding the Operation of the Cream Extruding Apparatus) * State shown in FIG. 2 (a) The extruding mechanism 30 is in the supply state P and the extruding chamber 17
Inside, the internal volume between both pistons 31 and 32 is large. The supply valve element 29 is in the open position and the discharge valve element 19 is in the closed position. The shaving cream is filled from the storage chamber 20 to the extrusion chamber 17 through the supply-side valve hole 27, the valve chamber 26, the nozzle hole 25, and the opening 24.

* From the state shown in FIG.
When the two operating portions 35 and 36 are pushed, the two pistons 31 and 32 approach each other in the pushing chamber 17 against the elastic force of the compression coil spring 37, and the space between the two pistons 31 and 32 is pushed. The internal volume is reduced to the discharge state Q. Therefore, the extrusion chamber 1
The shaving cream inside 7 is pushed out to the supply side valve hole 24 and the discharge side valve hole 16 by the pressure rise, and the supply valve body 29
Is pushed to the closed position and the discharge valve body 19 is pushed to the open position. Therefore, the storage chamber 20 and the supply side valve chamber 26 are shut off by the supply valve body 29 and the pushing chamber 17 is closed.
The backflow of the shaving cream from the storage chamber 20 to the storage chamber 20 is prevented, and the shaving cream in the extrusion chamber 17 passes only through the discharge-side valve hole 16, the valve chamber 15, and the discharge passage 14, and the blade body assembly 3 ( (See FIG. 1).

* The state where the two operation parts 35 and 36 are separated from the state shown in FIG. 3A. When the two operation parts 35 and 36 are separated, the two pistons 31 and 32 The pistons 31 and 32 are separated from each other by the elastic force, and the inner volume between the pistons 31 and 32 is increased to be in the supply state P. Therefore, a vacuum portion is generated in the push-out chamber 17, and the suction force causes the supply valve body 29 to be pulled to the open position and the discharge valve body 19 to be pulled to the closed position. Therefore, the extrusion chamber 17 and the discharge side valve chamber 15 are shut off by the discharge valve body 19, and the discharge side valve chamber 1 is closed.
The shaving cream remains in the vicinity of the cutting edge 5, the discharge passage 14 and the blade edge of the blade body assembly 3 (see FIG. 1). On the other hand, the shaving cream in the storage chamber 20 is supplied by the suction force to the supply-side valve hole 27, the valve chamber 26, the nozzle hole 25 and the opening 24.
To the extrusion chamber 17.

Use of a T-shaped razor When the above-mentioned operations on the two operation sections 35 and 36 are repeated according to the required amount of shaving cream, the shaving cream becomes close to the cutting edge of the blade assembly 3 (see FIG. 1). Up to the required amount. The user can apply this shaving cream to a face or the like and shave with a T-shaped razor.

* When only the tube 21 is pushed without operating both the operation parts 35 and 36, the tube cover 1b is removed from the head cover 1a by pushing the both locking buttons 9 and the shaving cream storage container 10
To release. The pushing mechanism 30 is in the supply state P. Depending on the required amount of shaving cream, this storage container 10
When the tube 21 is repeatedly pushed, the supply valve body 29 and the discharge valve body 19 are both brought into the open position by the shaving cream pushed out from the storage chamber 20, and the shaving cream is placed in the blade assembly 3 (see FIG. 1). The required amount is sequentially discharged to the vicinity of the cutting edge of ()).
