Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a knock-type stick-shaped cosmetic container with a return mechanism. The present invention relates to a knock-type rod-shaped cosmetic container having a return mechanism that allows the protruding cosmetic core to be stored in the container by advancing the cosmetic core and making a deeper knock.

[Prior art and its problems]

Conventional lock-type bar-shaped cosmetic containers allow the cosmetic core to be easily protruded from the container by knocking the tail plug during use, but in order to store the cosmetic core inside the container after use, the tail plug is It was necessary to press the protruding cosmetic core from the tip and push it into the container while keeping the button pressed. At this time, in conventional containers, force is applied to the protruding cosmetic core, which generally causes the soft cosmetic core to break or stain the fingertips when pushing it in, resulting in the protruding cosmetic core being stored inside the container. The disadvantage was that it required considerable care and effort.

Other conventional stick-type cosmetic containers include:
Two rings are provided at the front and rear of the tip of the three-part chuck to tighten the three-part chuck, and the cosmetic core is fed out by attaching and detaching the rear ring to the chuck, and the cosmetic core is retracted by attaching and detaching the front ring to and from the chuck. There is a knock-type cosmetic container. In such a cosmetic container, in order to attach and detach the ring, a stepped portion must be formed on the inner peripheral wall of the cosmetic container main body, and this formation further requires a relatively difficult manufacturing process. Also, since both rings must be moved a certain distance individually,
A space must be formed within the cosmetic container body in which the two rings can move independently, thus
The mechanism for feeding and retracting the cosmetic core had to be made longer.

[Purpose of invention]

The present invention was devised to eliminate these drawbacks, and its purpose is to create a lock-type cosmetic bar that allows the ring to be attached to and removed from the chuck without providing a step on the internal circumferential wall of the cosmetic container body. The purpose is to provide food containers.

Another object of the present invention is to provide a lock-type cosmetic bar container in which the two rings can be moved individually, but the overall movement distance is short.

Furthermore, another object of the present invention is to provide a lock-type, rod-shaped cosmetic container in which the amount of the cosmetic core that is fed out or retracted by one knob can be adjusted by increasing or decreasing the length of both rings. The goal is to provide the following.

[Summary of the invention] This invention basically consists of a cartridge tube that reciprocably stores a core chuck holding cosmetics at one end, has an annular packing fixed to the rear, and has openings at both ends. The cylinder body has two partition walls spaced apart from each other at the center of the cylinder body into which the cartridge cylinder is removably inserted from the tip opening, and a through hole with different diameters is formed at the center between the two partition walls. a feeding ring having a large diameter hole at the front and a small diameter hole at the rear; A return ring that can be slidably stored inside is stored, and is fixed to the tip of a notch part that is partially exposed and slidable in the rear opening of the cylinder body and is constantly pressed rearward by a spring. A tightening tip portion provided at the tip of the split chuck is located between the feeding ring and the return ring, and the split chuck
Both rings are composed of a main body in which the tip of a push rod extending through the two partition walls comes into contact with the rear end of the core chuck through the annular packing, and the split chuck has a small diameter of the feeding ring. When located in the hole or the return ring, the push rod is clamped, and when located between them, the push rod is released, and when the feed ring moves forward together with the split chuck and the push rod, The return ring is stored in the large diameter hole at the front and moved forward, and when the return ring is moved back together with the split chuck and the push rod, it retreats while sliding in the large diameter hole of the feeding ring. They are characterized by the fact that they retreat together after

[Example of idea]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a rod-shaped cosmetic container in a state where the cosmetic core is not drawn out. Main body 1
is a cylindrical body with both ends open, and a cylindrical cartridge holder 2 is fixed inside the tip thereof, and a cylindrical ring stopper 3 is further fixed to the end thereof. The cartridge holder 2 has a female screw portion 2a on the inner circumferential wall at the tip, and a hole 2 at the rear end through which the push rod 4 passes.
It has a bottom surface 2b provided with b'. The tip of the ring stopper 3 contacts the bottom surface 2b of the cartridge holder 2, and the rear end has a bottom surface 3b provided with a hole 3b' into which the three-piece chuck 7 slides.

At the tip of the main body 1, a hollow cylindrical cartridge tube 8 is screwed into a cartridge holder 2. The cartridge cylinder 8 has an inward protrusion 9 on the inner peripheral wall of the tip opening, a stepped portion 10 inside the center, and a male threaded portion 8a on the rear outer periphery that is screwed into the female threaded portion 2a of the cartridge holder 2. . The engagement between the cartridge cylinder 8 and the cartridge holder 2 is achieved by screwing the male threaded part 8a and the female threaded part 2a, but a leaf spring is provided inside the cartridge holder 2 to engage the two. You may also hold a meeting. Inside the cartridge cylinder 8, an outward protrusion 12a is provided at the rear end.
A core chuck 12, which has a tip and grips the rear end of the cosmetic core 11, is housed in a reciprocating manner. A compression spring 13 is disposed between the stepped portion 10 of the cartridge cylinder 8 and the outer protrusion 12a of the core chuck 12 so as to surround the core chuck 12. This spring 13 forces the core chuck 12 against the rear of the cartridge barrel 8 at all times. Further, a tail plug 14 having a hole into which the push rod 4 slides is fitted and fixed to the rear end of the cartridge cylinder 8. A ring-shaped gasket 15 for gripping the push rod 4 is fixed in the tail plug 14 by a gasket stopper 16. Although the gasket 15 can easily move the push rod 4 forward by a knocking operation, which will be described later, it needs to have enough gripping force to prevent it from being pushed back by the spring 12. This fixation of the tail plug 14 prevents the spring 13, core chuck 12, etc. from falling out of the cartridge tube 8 even when the cartridge tube 8 is removed from the main body 1.

Two rings are housed within the ring stopper 3, namely a feeding ring 5 and a returning ring 6. The feeding ring 5 is a cylindrical body that can slide in the axial direction within the ring stopper, and has a through hole with different inner diameters in its center, and the inner diameter of the front large diameter hole 5a' is the outer diameter of the return ring 6. The inner diameter of the rear small diameter hole 5b' is such that when the tightening tip 7b at the tip of the three-part chuck 7 is inserted therein, it is tightened inward and the push rod 4 is tightened. It is enough to hold it in place. The length D of the return ring 6 (see FIG. 2) is smaller than the length C of the large diameter hole 5a', so that the return ring 6 is slidable in the axial direction within the large diameter hole 5a'. . The inner diameter of the return ring 6 is the same as the inner diameter of the small diameter hole 5b', and is large enough to tighten the clamping tip 7b of the chuck 7 inward and clamp the push rod 4 when the clamping tip 7b of the chuck 7 is inserted therein. In order to allow the tightening tip 7b of the chuck 7 to be easily inserted into and removed from the small diameter hole 5b' of the feeding ring 5 and the return ring 6, the inner surfaces of the small diameter hole 5b' and the return ring 6 are tapered as shown. It is desirable that

A notch portion 17 is inserted into the rear end of the main body 1 so as to be able to reciprocate in the axial direction. The knob part 17
is a cylindrical body with an open end, and a female threaded portion 17a is formed inside the open end. The chuck 7 has a male threaded portion 7a at its rear end that screws into the female threaded portion 17a, and a tightening tip portion 7b at its tip.
is fixed to the tip of the notch portion 17. In this way, the chuck 7 and the notch portion 17 are fixed by screwing together, but they may also be fixed by adhesive or the like.

The push rod 4 extends through the chuck 7 and the notch portion 17, and its tip abuts against the rear end of the core chuck 12 so that it can be pressed. A protrusion 4a is provided at the rear end of the push rod 4 to prevent the push rod 4 from falling out of the chuck 7.

A compression spring 16 is disposed between the bottom 3b of the ring stopper 3 and the tip of the notch portion 17. Due to this spring 16, the notch portion 17 is constantly pressed rearward, and the chuck 7 is also pulled rearward. Therefore, the tightening tip 7b of the chuck 7 is inserted into the small diameter hole 5b' of the feeding ring 5, and is clamped between the feeding ring 5 and the push rod 4. This clamping prevents the chuck 7, the knob 17 and the spring 16 from slipping out.

FIG. 1 shows a normal state in which no external force is applied to the notch portion 17. From this state, when the notch portion 17 is pushed forward toward the tip against the repulsive force of the spring 16, the tightening tip portion 7b located within the small diameter 5b' of the feeding ring 5 will hold the push rod 4 while the feeding ring 5 until the tip of the cartridge holder 2 comes into contact with the bottom surface 2b of the cartridge holder 2 (the moving distance of the feeding ring 5 is assumed to be A). By this forward movement, the tip of the push rod 4 passes through the hole 2b' in the bottom surface 2b, pushes the rear end of the core chuck 12 against the tightening force of the packing 15, and moves the cosmetic core 11 into the cartridge tube 8.
protrude from the opening at the tip. At this time, the return ring 6 is housed in the large diameter hole 5a' of the payout ring 5 and moves forward together.

Further, when the knob portion 17 is continued to be pressed, the tightening tip 7b of the chuck 7 is pushed out of the small diameter hole 5b' of the feeding ring 5, moves into the large diameter hole 5a',
There, it expands outward and releases the push rod 4 as shown in FIG. Although the push rod 4 is released, it is not pushed back by the spring 13 because it is held by the gasket 15.

When the external force is removed from the notch 17, the spring 16
As a result, the notch portion 17 is pushed back to the rear, and the chuck 7 is similarly pushed back. At this time, since the feeding ring 5 is not fixed, the tightening tip 7b of the chuck 7 moves rearward together with the feeding ring 5 in a state where it is caught. When the rear end of the feeding ring 5 comes into contact with the bottom surface 3b of the ring stopper 3, it can no longer move rearward, but the chuck 7 moves further rearward with the movement of the notch 17, and the tip end 7b of the feeding ring 5 and the push rod 4. Therefore, the chuck 7 can no longer move rearward, and the push rod 4 is clamped by the tip 7b. When the above-described knocking operation is continued, the push rod 4 is drawn out, and the cosmetic core 11 is drawn out accordingly. The amount by which the cosmetic core is fed out by one knocking operation can be arbitrarily determined by adjusting the length of the feeding ring 5 or by adjusting the length of the ring stopper 3. can. Therefore,
When you want to adjust the amount drawn out by one knocking operation depending on the thickness or stiffness of the cosmetic lead,
Adjustment can be made by simply adjusting the lengths of the ring stopper 3 and the feeding ring 5.

Next, when the notch portion 17 is pushed further toward the tip end than pushing the tightening tip portion 7b of the chuck 7 out of the small diameter hole 5b' of the feeding ring (see Fig. 2), the tip of the tip portion 7b becomes Continue to push the return ring 6 until the tip of the return ring 6 comes into contact with the bottom surface 2b of the cartridge holder 2. When the notch part 17 is further pushed forward, the tip part 7b is squeezed and pushed into the return ring 6, and cannot be advanced any further (see FIG. 3). Since the tightening tip 7b of the chuck 7 clamps the push rod 4, the return ring 6, chuck 7, and push rod 4 are integrated. Therefore, when the external force on the notch part 17 is removed, the repulsive force of the spring 16 causes the notch part 17 to open.
and the chuck 7 is pushed back backwards,
The push rod 4 is also pushed back against the gripping force of the gasket 15. At this time, since the feeding ring 5 is not fixed, it moves rearward together with the chuck 7 due to the abutment between the rear end of the return ring 6 and the stepped portion 5c of the feeding ring 5. Bottom surface 5 of feeding ring 5
When b comes into contact with the bottom surface 3b of the ring stopper 3, the pay-out ring 5 can no longer move, while the chuck moves further rearward. Therefore, the return ring 6 is disengaged from the tip 7b, and the tip 7b moves between the small diameter hole 5b' of the feeding ring 5 and the push rod 4, and holds the push rod 4 therebetween. At this point, the backward movement of the chuck 7, push rod 4, and knob portion 17 is stopped.

As described above, the moving distance of the push rod returned by one return knock operation corresponds to the moving distance A+(C-D) of the return ring 6. Of the moving distance of the return ring 6, (C-D) is the moving distance within the feeding ring 5, so the return ring 6
This means that the feeding ring 5 has apparently only moved by the moving distance A. That is, since the return ring 6 is housed and movable within the feeding ring 5, it is only necessary to form a space within the main body for reciprocating the feeding ring 5 in the axial direction. There is no need to create additional space within the main body for movement.
Therefore, both rings and the bottom surface 3 of the ring stopper 3
b and the bottom surface 2b of the cartridge holder 2. It can be much shorter.

[Effect of idea]

As explained above, when the shape of the feeding ring is formed so that the return ring can be stored in the feeding ring according to the present invention, a projection for removing each ring is formed between both rings in the cosmetic container main body. There is no need to provide Therefore, while it is possible to increase the distance that these rings move back and forth, it is also possible to reduce the distance that the entire ring moves, thereby shortening the total length of the mechanism for feeding and retracting the cosmetic container. I can do it.

Furthermore, the length of the cosmetic core that is fed out or drawn back by a single knocking operation can be changed by adjusting the lengths of the feeding ring and the return ring. There is no need to change the cosmetic core, and therefore the application of the cosmetic container is expanded.
