2. Description of the Related Art As shown in FIGS. 1, 2 and 3, a conventional cartridge type cosmetic container is configured such that a cartridge 2 is detachably mounted on a cosmetic container main body 1, and a slit inside the cartridge 2 is provided. A shaft chuck 3 for supporting a cosmetic material is built in the shaft 3, and the core chuck 4 is urged backward by a spring 5 wound around the slit shaft 3, while the slit shaft 3 is
At the rear end, a rotation stop rib 7 that engages with the rib 6B of the extrusion punch 6 in the container body 1 is used to stop rotation.

[0003] A spring 10 is wound around the extrusion punch 6, and constantly pushes the extrusion punch 6 rearward. When the cartridge 2 and the container main body 1 are rotated in this state, the pushing punch 6 is opposed to the spring 10, and the spline structure of the rotation stopping rib 7 of the slit shaft 3 and the rib 6 B of the pushing punch 6 causes To advance in the axial direction. The urging force of the spring 10 wound around the extrusion punch 6 is applied to the extrusion punch rib 6B and the rotation stopper.
The force acts on the slit shaft 3 via the bush 7 and a force for reversing the cartridge 2 acts.

For this reason, the leaf spring 9 is an essential member for preventing reverse rotation. Further, since the spring 5 on the cartridge 2 side is compressed by the advance of the pushing punch 6, a force is exerted on the cartridge 2 to fly out of the container body 1. For this reason, the C-shaped locking member 11 for preventing the protrusion has been used for preventing the protrusion.

[0005]

[Problems to be solved by the invention] As described above,

Is performed, and the concave and convex portions formed on the plate spring are engaged with each other, so that the cartridge is securely anchored to the container body.

When the cartridge is rotated in this state,
The extrusion punch advances by the synchronous rotation of the cartridge and the core chuck. The spring wound around the push punch exerts a biasing force rearward to exert a force for reversely rotating the cartridge, but the cartridge does not run idle due to the pressing of the leaf spring. Here, the leaf spring is fixed to the container body in a non-rotatable and immovable state with respect to the container body,
Recess (concave convex portion of the leaf spring (the concavo-convex portion) Cartridge
The cartridge does not fly out of the container body since the cartridge is in the engaged state. When the used cartridge is pulled out, the core and the cartridge are separated from each other, and at the same time, the extrusion punch automatically returns. Since the extrusion punch enters the container body, the extrusion punch is not damaged.

It serves as a rotation stop .

The container body 23 includes an outer cylinder 35 and the outer cylinder 35.
An inner cylinder 36 fitted and fixed to the inner cylinder 36, an extrusion punch 32 having a plurality of projections engaged with a spiral portion 38 of the inner cylinder front portion 37, and the extrusion punch 32 wound around the extrusion It is composed of a spring 39 which is biased, and a leaf spring 42 which is positioned on the inner periphery of the front part of the container body 23 by a tail plug 40 and a locking hole 41 which prevent the push-out punch 32 from coming off by the spring 39.

The extrusion punch 32 wound around the spring 39 is inserted from the rear of the inner cylinder 36, and the spiral portion 38 and the extrusion punch 32 are inserted.
Helical projection 43 projecting from
Stop this with Further, a leaf spring 42 having a locking hole 41
Is forcibly press-fitted from the rear of the outer cylinder 35 in a state where is locked to the front part of the inner cylinder 36, thereby completing the assembly. The above leaf spring 4
The leaf spring 42 is fixed to the container main body 23 so as not to rotate and cannot move by the locking holes 41 of the projections 4.
Since the position 4 is always at the fixed position, the position of engagement with the cartridge 20 is determined. The leaf spring 42 is curved so as to protrude inward of the container main body 23, and holds the cartridge 20 to the container main body 23 by the elastic force of the curved portion. In the present embodiment, the convex portion 44 is formed on the curved portion. On the other hand, a concave portion 46 with which the convex portion 44 is engaged in a fitted state is formed on the outer surface of the cartridge 20. The cartridge 20 can be reliably held on the container main body 23 by the mutual engagement between the convex portion 44 and the concave portion 46. That is, in this structure, the cartridge 20 is not only held on the container main body 23 by the elastic force of the leaf spring 42 but also held on the container main body 23 by the engagement between the concave portion 46 and the convex portion 44. With such a structure, the holding of the cartridge 20 is ensured, and the cartridge 20 does not easily come off the container main body 23.

Next, the operation of the embodiment of the present invention will be described. When assembling the cartridge 20 and the container body 23 as described above, when the cartridge is first inserted through the front opening 45 of the container body 23, the resistance of the light leaf spring 42 is felt, and the insertion is further performed. Continue cartridge 20
Protrusions 44 of the recess 46 and the leaf spring 42 is front locking ribs 33 and the core chuck 25 under the longitudinal ribs 34 of the extrusion punch 32 simultaneously with the engagement are engaged in. This completes the assembly of the cartridge 20 and the container body 23.

When the cartridge 20 is rotated in this state, the pushing pier 32 pushes the butt 26 of the core chuck 25 because the front end locking rib 33 of the pushing punch 32 and the vertical rib 34 of the core chuck 25 are engaged. The bat 26 is engaged with the engagement grooves 30 and 31 of the cartridge 20, and the helical portion 38 of the inner cylinder 36 is engaged with the projection 4 of the pushing punch 32.
3 is screwed, the core chuck 25 itself is pushed out.
The punch 32 stops rotating, and the extrusion punch 32 moves forward.

The spring 3 wound around the extrusion punch 32
Due to 9, a force for urging the extrusion punch 32 backward always acts. However, since the cartridge 20 is pressed by the leaf spring 42, even if the user releases the hand from the cartridge 20 during makeup , the pushing punch 32 does not rotate backward and return .

Further, since the concave portion 46 of the cartridge 20 and the convex portion 44 of the leaf spring 42 are engaged with each other, even if the pressure of the leaf spring 42 is weakened,
As a result, the cartridge 20 does not fly out of the container body 23. Further, since the locking hole 41 at the rear portion of the leaf spring 42 is engaged with the front portion 37 of the inner cylinder, the leaf spring 42 cannot rotate and cannot move with respect to the container body 23. Since the convex portion 44 of the leaf spring 42 engages with the concave portion 46 of the cartridge 20 to press the cartridge 20, the cartridge 20 does not jump out of the container body 23. In this state, the cartridge 20 is
3, the concave portion 46 of the cartridge 20 is disengaged from the convex portion 44 of the leaf spring 42, and the cartridge 20 is removed.
Is detached from the container body 23. When the cartridge 20 is pulled out, the pushing punch 32 is automatically returned by the urging force of the spring 39 wound around the pushing punch, thereby facilitating insertion of a new cartridge. When the cartridge 20 is pulled out of the container body 23, the locking hole
41 prevents the leaf spring 42 from rotating with respect to the container body 23
In addition, since they are engaged in a state where they cannot move, the leaf spring 42 does not jump out of the container body 23. Thus, the leaf spring 42 can be engaged with a new cartridge to be inserted in the same manner as described above .

Further, a convex portion 80 (concavo-convex portion) is formed in the rear part of the leaf spring 75 in a cut-and-raised shape, and this convex portion 80 is engaged with a concave portion 81 (concavo-convex portion) formed at the base end of the cartridge 70. In some cases, the cartridge 70 is prevented from jumping out of the container body 77. Further, since the outer peripheral surface of the cartridge 70 is pressed by the inwardly curved portion of the leaf spring 75, even if the hand is released from the cartridge 70 during the operation, the pushing punch 72
Never goes back.

In the cartridge type stick-shaped cosmetic dispensing container, a leaf spring is a known technique, but conventionally, a leaf spring has been used in a method of rotating the container synchronously with the cartridge in a container body in which a holder is installed. That is, it has been used only as an axial resistance member. On the other hand, in the above-described fourth embodiment, a leaf spring is brought into contact with the cartridge, the cartridge and the leaf spring are relatively rotatable, and the spring wound around the extrusion punch prevents reverse rotation of the extrusion punch. The spring and the concave and convex portions formed on the cartridge prevent the cartridge from jumping out, and furthermore, since the leaf spring is immovably attached to the container body, the leaf spring itself can be prevented from jumping out when the cartridge is pulled out. Further, since the leaf spring is fixed at a fixed position with respect to the container body, the uneven portion is positioned at a fixed position, and engagement with the cartridge is always performed at a fixed fixed position.

[0027]

According to the present invention, the leaf spring for preventing the cartridge from popping out is attached to the container body so that it cannot rotate and cannot move. Therefore, when the cartridge is pulled out, the leaf spring does not come out of the container body together with the cartridge. The leaf spring can be reused as it is. In addition, the conventional example
Even without using the C-shaped locking member 11, in addition to the elastic force of the leaf spring, the cartridge is held in the container body by the concave and convex portions mutually engaging between the leaf spring and the cartridge. Prevent and container book
