Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a knock-type cosmetic container which can be used by extruding a cosmetic such as an eyeliner or an eye shadow by a knocking operation.

(Conventional technology) Conventionally, in a container in which a solid bar-shaped cosmetic is accommodated in a dispensable manner, a screw feed mechanism is used as a dispensing mechanism, and a user needs a rotating operation to make the cosmetic protrude. There was trouble to use. In addition, some containers containing liquid cosmetics can supply cosmetics to the ears by knocking with one hand by using a valve, but the valve is assembled or the cosmetics are discharged from a tank. Therefore, the structure has been complicated, for example, by providing a flow passage for air introduced into the tank in place of the cosmetic.

(Problems to be Solved by the Invention) In order to solve the above-mentioned drawbacks of the prior art, for example, as shown in JP-A-57-110210, a feeding chuck is provided inside the container body, and A push rod for extruding cosmetics is attached to a removable cosmetic storage cartridge with respect to the container body, the container body and the cosmetic storage cartridge are fitted, and the push rod is gripped by the feeding chuck, and the push rod is pushed by the feeding chuck by knocking operation. Knock-type cosmetic containers have been devised that are pushed forward to extrude cosmetics. But,
This invention also had the following problems. That is, when the push rod is inserted into the inside of the delivery chuck in order to make the delivery chuck hold the push bar, it is necessary to keep the push bar gripping part of the delivery chuck open, so that it is necessary to maintain the knocking state, It is necessary to keep pushing the knocking body with a finger, which is extremely troublesome and troublesome. Therefore, an object of the present invention is to provide a knock-type cosmetic container that solves such a problem.

(Means for Solving the Problems) In order to achieve the above object, a knock-type cosmetic container of the present invention is provided such that a push rod 1 for pushing out a cosmetic can be moved forward on a shaft 5 containing cosmetics and the shaft 5 can be moved forward. A cosmetic storage cartridge 9 attached to project from the back of the container, and a feed chuck 2 for inserting the push rod 1 of the cosmetic storage cartridge 9 therein, gripping the same, and advancing the gripped push rod 1 by a required stroke by a knocking operation. And a container body 4 provided inside the shaft 3. A projection 19 is provided on a side surface of a knock body 13 for advancing the feeding chuck 2 in the container body 4, and the shaft 3
The projection 19 fits into the inner surface of the
When the knock body 13 is rotated at the forward position, the projection 19 fits in and the circumferential lateral groove 25 that prevents the knock body 13 from retreating,
The projection 19 is fitted and locked in the depth of the lateral groove 25, and the recess 27 that prevents the projection 19 from coming out of the lateral groove 25 due to unintended rotation of the knock body 13 is provided so as to communicate with each other. This is the configuration.

(Operation) When the push rod 1 is gripped by the feeding chuck 2 when the cosmetic storage cartridge 9 is fitted to the container body 4, first, the projection 19 of the knock body 13 is fitted into the vertical groove 24 formed on the inner surface of the shaft 3. Then, the knocking body 13 is rotated at the advanced position, the projection 19 is fitted into the lateral groove 25, and the knocking body 13 is further retracted a little behind the lateral groove 25 to thereby project.
19 is fitted into the recess 27 and locked. In this state, the knocking body 13 is reliably prevented from retreating, so that even when the finger is released from the knocking body 13, the feeding chuck 2 is knocked and remains open, so that the push rod 1 is inserted into the inside of the pulling chuck. Work becomes extremely easy.

(Example) Hereinafter, an example is described based on a drawing. First, FIGS. 1 to 4 show an embodiment in which the cosmetic is in the form of a solid bar. In FIG. 2 showing the container body 4,
The shaft 3 comprises a shaft body 10, a slightly larger connecting shaft portion 11 screwed to the front end thereof, and a tail plug 26 which is press-fitted into the rear end of the shaft body 10. The feeding chuck 2 is provided inside the shaft 3. ing. The feed chuck 2 has a push rod housing tube 12 connected to its rear end, and a knocking body 13 fitted on the rear end of the push rod housing tube 12 protruding from the rear end opening of the shaft body 10. A fastener 15 is attached to the outer peripheral portion of the divided push rod gripping portion 14 at the front end of the feeding chuck 2, and a flange 16 provided around the outer surface of the push rod receiving tube 12 and a front end inner surface step 17 of the shaft body 10 are provided. A spring 18 is interposed therebetween, so that the feeding chuck 2, the push rod housing tube 12, and the knock body 13 are integrally urged rearward. Therefore, the push bar gripping portion 14 of the feeding chuck 2 is usually pulled into the fastener 15 at its rear end. When the knock body 13 is knocked forward, the push rod grip portion 14 of the feeding chuck 2 moves forward, escapes from the fastener 15, and separates. When the knock is released, the spring 18 returns to the original position again. As shown in FIG. 4, a projection 19 is formed on the side surface of the knocking body 13, and the projection 19 is fitted on the inner surface of the tail plug 26, which is a component of the shaft 3, so that the axial longitudinal groove 24 can be advanced. And a lateral groove 25 which is bent in the circumferential direction at the front end position and into which the projection 19 can be similarly fitted. In addition, a concave portion 27 for locking the projection 19 in the lateral groove 25 is provided at a leading edge of the lateral groove 25. At a required position on the peripheral wall of the tail plug 26, a slot 28 for facilitating elastic deformation of the tail plug 26 is provided in order to easily fit the projection 19 of the knock body 13 into the vertical groove 24 of the tail plug 26. Next, in FIG. 3 showing the cosmetic storage cartridge 9, the shaft 5 is opened at the front and rear ends, has a small diameter portion 20 at the rear end, and has a screw portion 21 formed on the outer surface of the small diameter portion 20. . The solid bar-shaped cosmetic 6 is accommodated inside the large diameter portion of the shaft 5 in front of the small diameter portion 20, and a receiving member 7 slidable in the axial direction inside the shaft 5 is provided at the rear end of the solid rod-shaped cosmetic 6. It is fitted. The receiving member 7 has a small-diameter cylindrical portion 22 having an open rear end on the rear surface. A push rod holder 8 made of an elastic material such as rubber and having a through hole 23 is fixedly fitted at a position rearward of the receiving member 7 inside the rear end small diameter portion 20 of the shaft 5. The push rod 1 has its front end inserted through the push rod holder 8 and is fitted and fixed in the small-diameter cylindrical portion 22 of the receiving member 7. An embodiment in which the push rod holder 8 is integrally formed with the shaft 5 made of resin is also possible.
Next, FIG. 1 shows the entire structure in which the cosmetic storage cartridge 9 is assembled to the container main body 4. The knock body 13 is knocked, and the projection 19 is advanced in the vertical groove 24.
By rotating the projection 13, the projection 19 is inserted into the lateral groove 25 and locked by the concave portion 27, thereby keeping the feeding chuck 2 in an open state and inserting the push rod 1 into the inside thereof. In this state, the rear end small diameter portion 20 of the shaft 5 of the cosmetic storage cartridge 9 and the front end of the connection shaft portion 11 of the container body 4 are screwed. When the knocking body 13 of the container body 4 is knocked forward, the feeding chuck 2 advances the push rod 1, and is pushed by the push rod 1, and the receiving tool 7 advances to cause the solid bar cosmetic 6 to protrude from the front end opening of the shaft 5. The receiving tool 7 finally advances to the front end of the shaft 5 so that substantially the entire solid bar cosmetic 6 can be used.

Next, FIG. 5 shows the cosmetic storage cartridge 9 of the embodiment when the cosmetic is a liquid. Here, the shaft 5 is composed of a shaft main body 29 and a front shaft 30, a small diameter portion 20 is provided at the rear end of the shaft main body 29, and a screw portion 21 is formed on the outer surface thereof.
The ear 31 is attached to the front end opening of the. A pipe fixing base 32 is disposed immediately behind the ear 31, and the front end of the liquid guide pipe 33 fitted in the center hole thereof is inserted into the inside of the ear 31. Inside the shaft 5, a liquid cosmetic 34 is stored,
At the rear position, a piston 35 which is in contact with the inner surface of the shaft main body 29 in a watertight manner and which can move forward is arranged. The piston 35 has a small-diameter cylindrical portion 36 on the rear surface, and the front end of the push rod 1 is inserted and locked at the same location. The push bar 1 protrudes long behind the shaft 5. When the piston 35 is pushed forward by the push rod 1, the piston 35 moves forward,
When the push rod 1 is not pushed, it is stopped and fixed in place, and is in contact with the inner surface of the shaft body 29 with an appropriate frictional force so as not to be retracted by the pressure of the liquid cosmetic. The structure of the container main body 4 fitted with the cosmetic storage cartridge 9 is the same as the container main body in the above-described embodiment shown in FIG.

(Effects of the Invention) The present invention is as described above. When the cosmetic is solid, the convenience of easily dispensing the cosmetic by one-knock operation without rotating with both hands as in the related art is obtained, and When the cosmetic is a liquid, the valve is not used as in the related art, so that the structure can be prevented from becoming complicated. In particular, when the cosmetic storage cartridge 9 is fitted to the container body 4, the disengaged state of the feeding chuck 2 can be maintained by fitting the projection 19 of the knock body 13 into the lateral groove 25. The operation of inserting the push rod 1 is greatly facilitated, and the container body 4 and the cosmetic storage cartridge 9
This can reduce the trouble and trouble of the fitting work. In addition, the protrusion 19 is fitted into the concave portion 27 at the back of the lateral groove 25 and locked, so that the lateral groove caused by the unintended rotation of the knock body 13 is formed.
Since the protrusion 19 can be prevented from coming off from the projection 25, the separation state of the feeding chuck 2 can be reliably maintained, and the disadvantage that the feeding chuck 2 closes when the push rod 1 is inserted can be prevented.
