Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge-type cosmetic pressure container that pressurizes and pushes out cosmetics by rotation, and is particularly suitable for easy discharge of liquid cosmetics and extrusion of volatile solid stick cosmetics. And a cartridge-type cosmetic pressure container. The invention also relates to the cartridge itself for use with such a pressurized container.

[0002]

BACKGROUND OF THE INVENTION A liquid piston having a piston type structure which is rotated by rotating a container is disclosed in Japanese Utility Model No. 6
3-185485 "Applicator". But,
Since this applicator is not of the cartridge type, it is not possible to change the color of the cosmetics in one container, and the container must be discarded after use. In the cartridge type, there is a Japanese Utility Model No. 3-17781 "Cartridge type airtight container", but this has a screw shaft 32 incorporated inside the cartridge, the mechanism is complicated, the number of parts of the cartridge itself is large, and the cost is high. In addition to the difficulty of becoming high, the knocking action pushes the piston, which makes it difficult to adjust the discharge amount and is not suitable for discharging highly viscous liquid cosmetics. Further, Japanese Utility Model Publication No. 4-46683 "Coating Container" also discloses the cartridge 16 of the liquid cosmetic 29, which is also a knock type and has the same drawbacks as described above. There are drawbacks such as the inconvenience of not being able to replace it together with the cartridge, and the mechanism of the main body being extremely complicated and costly.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a cosmetic, in particular, a liquid cosmetic containing an applicator is of a cartridge type, which has a simple structure and a small number of parts, and can be manufactured at a low cost. The object was to realize a pressurized container for cosmetics, to enable fine adjustment of the discharge amount steplessly at the time of use, and to easily extrude even highly viscous liquid cosmetics. is there.

[0004]

Therefore, the present invention provides a cartridge-type cosmetic container comprising a combination of a cartridge and a holder which are fitted so as to be rotatable relative to each other. A piston is slidably installed inside the container, the front side of which is used as a cosmetics storage chamber (or a liquid storage chamber), and two or more arc-shaped sections are provided at the rear end of the cartridge cylinder for elasticity. It is constructed by extending it and providing a female screw on its inner circumference. A holder for mounting this cartridge has a vertical groove formed on the inner periphery of its inner cylinder, and inside the inner cylinder, the vertical groove is engaged with the vertical groove and is guided forward and backward, and the inside of the cartridge is mounted. A screw rod, which is in contact with the piston and can be screwed into the female screw, is arranged by being pressed by a push spring from the rear end. When the cartridge is mounted on the holder, the outer circumference of the elastic arcuate section comes into contact with the inner circumference of the tip of the inner cylinder and is preferably pressed radially inward, and the female thread on the inner circumference of the arcuate section is the male thread of the threaded rod. When the holder is rotated relative to the cartridge, the screw rod advances and pushes the piston from the rear side to push out the cosmetic material. In the case of liquid cosmetics, for example, a brush-shaped application body is fitted to the front end of the liquid storage chamber, and the cosmetics are discharged through this. In the present invention, since the cosmetic is discharged by relative rotation of the holder, unlike the knock-type container described above, it is easy to make fine adjustment in a stepless manner. When a stick-shaped cosmetic is placed in the cosmetic storage chamber instead of the liquid cosmetic, the cosmetic can be pushed out continuously by pressing the piston by the rotation of the holder, and in this case, the airtight cap is covered. By crowning, it becomes possible to make the stick-shaped cosmetic material volatile.

[0005]

In the cartridge type cosmetic pressurizing container of the present invention, the screw rod disposed in the holder advances by the relative rotation of the holder with respect to the cartridge to push the piston in the cosmetic accommodating chamber to discharge or push out the cosmetic. Therefore, by applying a strong rotational force to the holder, even a highly viscous cosmetic material can easily overcome the resistance force and be ejected, and an excellent effect that the knock type does not have can be achieved.
Since the rotation amount can be adjusted steplessly, the discharge amount can also be adjusted steplessly. By changing the cartridge, it is easy to change the color of the cosmetic with the same holder, and since the application body can be changed with the replacement of the cartridge, it is hygienic and the application of cosmetics is always easy and comfortable to draw. it can.

[0006]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a vertical sectional view showing a first embodiment of the present invention.
Basically, the cartridge type cosmetic pressurizing container of this embodiment comprises a cartridge 1 containing a liquid cosmetic and a holder 15 thereof. The cartridge 1 is composed of a cartridge tube 2 having a right cylindrical hole inside and a substantially conical holding tube 3 fitted to the tip of the cartridge tube. It has a pipe 5 for guiding liquid cosmetics. The rear end of the applicator 4 is airtightly held by the packing 7 with respect to the inner circumference of the cartridge cylinder 2.
The central hole of is connected to the pipe 5. As can be seen from FIG. 1, the inner circumference near the rear end of the cartridge cylinder 2 has a step portion, and a piston 8 which is slidable in an airtight manner with the inner circumference of the cartridge cylinder is seated therein. A cosmetic material storage chamber 9 is formed between the front surface of the piston 8 and the rear surface of the packing 7. When the cosmetic C (see reference numeral C in FIG. 3 described later) is liquid,
The storage chamber 9 is also called a liquid storage chamber. The airtight structure of the piston 8 may be a normal structure, but an O ring 6 as shown in FIGS. 2 and 3 described later can be used.

A feature of the cartridge 1 of the present invention is that the rear end of the cartridge tube 2 is extended rearward as two or more elastic arc-shaped sections 10. Since the arcuate section 10 is essentially the same in the second embodiment, a description will be given with reference to FIG. 3 relating to the second embodiment.
Two split grooves 11 are formed at the rear end of the cartridge cylinder 2, whereby two arcuate segments 10 are formed separately. Depending on the case, three or more split grooves 11 and arcuate segments 10 may be formed. In any case, since the arcuate section 10 has elasticity, it is attached from the open state (non-use state) as shown in FIG. 3 to the holder as shown in FIGS. 1, 2 and 5 and compressed. It can be bent in a reduced diameter state (in use). As shown most clearly in FIG. 3, a female screw 12 is formed on the inner periphery of the arcuate section 10. It is preferable that the female screw (and the male screw of the screw rod 24 described later that meshes with the female screw) have a pitch as small as possible. Reference numeral 14 is a locking portion between the cartridge and the holder, which is constituted by an undercut and a convex ring between them. The arcuate section 10 may have an internal thread 12 as an inner diameter that can be screwed into a threaded rod from the beginning, and it is not essential to reduce the diameter in the radial direction.

Returning to FIG. 1, the holder 15 is constructed by integrally fixing an outer cylinder 16, a joint cylinder 17 and an inner cylinder 18 in the illustrated example, and the locking portion 14 is the inner peripheral portion of the rear end of the joint cylinder 17. Is formed as a convex ring (correspondingly, as an undercut at the rear end of the cartridge). As shown in FIG. 1, two vertical grooves 19 are formed on the inner circumference of the inner cylinder 18 in the illustrated example. The inner circumference 20 of the front end of the inner cylinder 18 is slightly tapered in order to easily receive the rear end of the arcuate section 10 at the rear end of the cartridge. Reference numeral 21 denotes an inner protrusion protruding from the inner circumference of the inner cylinder 20.

The outer cylinder 16 is closed at the bottom 22, and a screw rod 24 is arranged in the outer cylinder 16 via a pressing spring 23. The screw rod 24 has an external thread formed on the outer periphery thereof to be screwed with the internal thread 12 of the arcuate section 10 of the cartridge. The length of the screw rod 24 is such that when the cartridge 1 is mounted in the holder 15, the screw rod 2 is pressed by the pushing spring 23 from the rear end.
The tip of 4 enters into the arc-shaped section 10 and the first one pitch of the male thread is set to be long enough to contact the female thread 12. The rear end of the screw rod 24 has a large diameter portion, and the guide protrusion 25 on the outer periphery thereof engages with the vertical groove 19 of the inner cylinder 18. A return spring 26 is inserted between the guide protrusion 25 and the inner protrusion 21. This spring is screwed into the cartridge 24
Holder 15 when cartridge 1 is
When it is pulled out from the screw rod 24,
However, the return spring 26 is not essential because the screw rod 24 that has been advanced is returned to the original position by pushing the next cartridge into the holder without the return spring 26. In FIG. 1, reference numeral 29 is a cap, which has an airtight structure for preventing leakage of the liquid cosmetic material in the illustrated example.

The usage state will be described. First, the cartridge 1 is inserted into the joint cylinder 17 of the holder 15 with the rear end opened as shown in FIG. At this time, the screw rod 24 in the holder 15 is pushed by the pushing spring 23 and is projected slightly above the position shown in FIG. When the cartridge 1 is inserted sufficiently deeply, the arcuate section 10 at the rear end of the cartridge cylinder comes into contact with the inner circumference 20 at the front end of the inner cylinder 18 and elastically bends radially inward,
Push in further to lock 14 (undercut and convex ring)
Engage. At this time, the internal thread 1 of the arc-shaped section 10
2 and the first one pitch of the male screw of the screw rod 24 hit and the screw rod 24 is pushed down. Then, when the holder outer cylinder 16 is rotated relative to the cartridge, the screw rod 24 rotates with respect to the cartridge together with the outer cylinder, and at the same time, the internal thread 12 of the arc-shaped section 10 in which the tip of the male screw is narrowed from the surroundings. Biting, the screw rod 24 is advanced by screwing with the female screw. Screw rod 2 that advances when the holder is further turned
Since the tip of 4 hits the bottom of the piston 8 and moves it forward, the liquid cosmetic material in the liquid storage chamber 9 is pushed and leaches from the pipe 5 to the applicator body 4. Since the amount of rotation of the holder can be changed steplessly, if the pitch between the male thread and the female thread is fine, the leaching of the cosmetic can be adjusted in a very delicate stepless manner. Further, when the viscosity of the cosmetic material is high, there is a strong resistance to the advance of the screw rod, but if a correspondingly strong rotational force is applied to the holder, a highly viscous cosmetic material can be easily discharged in an arbitrary amount. In this way, it is possible to finely adjust the discharge by skillfully combining the rotation amount and the rotation force.

FIG. 2 is a vertical sectional view showing a second embodiment of the present invention. This embodiment is a type in which the holder cannot be turned backward from the cartridge. The cartridge 1 used in this embodiment is shown in detail in FIG. 3, which is characterized by a ratchet pawl 13 on the outer periphery near the rear end of the cartridge barrel 2.
Is provided. The planar shape of the ratchet pawl 13 is as shown in FIG. 4, and the holder 1
As shown in FIG. 2, a ratchet 27 is provided on the inner circumference of the outer cylinder 16 of
Is pressed and attached to the push spring 23b. The ratchet 27 is shown in the unfolded state in FIG.
By the meshing shape of the pawls 13 and the ratchet teeth 28, the holder can be relatively rotated clockwise (in the direction of arrow A in FIG. 4), but cannot be rotated in the reverse direction. In the first embodiment without the ratchet and the ratchet pawl, the holder can be turned backward, and even if the holder is turned backward, the instrument will not be broken immediately. Since it retreats from 8 and moves away, the next few regular rotations will be idle for the first few rotations and cosmetics will not come out. The second embodiment prohibits this and is limited to only regular rotation so as to always secure the forward position of the screw rod 24, and is preferable in that the user does not perform an unnecessary operation.

Incidentally, the holder 15 in the second embodiment.
The push spring 23a has a different shape from FIG. 1 and is stronger, but the essential function is the same. Also,
The return spring 26 in FIG. 1 is omitted in FIG. Other configurations in FIG. 2 are basically the same as those in FIG.
Further, in the cartridge 1 shown in FIG. 3, 30 is a temporary cap for the cartridge. Other configurations of the cartridge 1, that is, the cartridge cylinder 2, the holding cylinder 3, the applicator 4, the pipe 5, the O-ring 6, the packing 7, the piston 8,
The liquid storage chamber 9, the elastic arcuate section 10, the split groove 11, the female screw 12 on the inner periphery thereof, and the undercut 14 are the same as those described in the first embodiment.

The rotary piston pushing function of the present invention is characterized in that it is possible to easily push out even a highly viscous cosmetic material by a strong rotating force as described above. FIG. 5 is a vertical cross-sectional view showing a third embodiment of a cartridge-type cosmetic pressure container in which this feature is applied to a solid stick cosmetic. In this example, the cartridge 1 is composed only of a cartridge cylinder 32 having a right cylindrical hole and a stick-shaped cosmetic material 34 contained in the cartridge cylinder 32. As in the previous example, the piston 8 which is slidable in an airtight manner is housed in the cartridge cylinder 32. By covering the tip of the cartridge barrel 32 with an airtight cap (not shown, but similar to the temporary cap 30 in FIG. 3), this cartridge can be used for highly volatile stick-shaped cosmetics. .

In FIG. 5, the structure of the holder 15 is the second.
The embodiment is the same as that shown in FIG. 2, and the screw rod 24 guided (25) to the vertical groove 19 is attached to the pushing spring 23a inside the integral outer cylinder 16, joint cylinder 17 and inner cylinder 18. The action of advancing by screwing the male thread of the screw rod 24 forward with the female thread 12 of the arcuate section 10 at the rear end of the cartridge that is compressed and accommodated and is squeezed by the inner circumference 20 of the tip of the inner cylinder, and the ratchet 27.
The action of engaging with the ratchet pawl 13 of the cartridge 1 to prohibit reverse rotation is the same as in the previous example.

[0015]

As is apparent from the above description, the cartridge type cosmetic pressurizing container of the present invention has a simple mechanism for both the cartridge and the holder and a small number of parts. Has the advantage that it can be slim and can be manufactured at low cost. Since the cartridge type cosmetic pressure container of the present invention is a rotary type, unlike the conventional knock type product, it is very easy to adjust the discharge amount or the extrusion amount of the cosmetic substance, and unlike the knock type, the cosmetic resistance Since it is possible to give a strong rotational force according to the above, there is an advantage that a cosmetic having high viscosity can be discharged. In the mode in which the ratchet mechanism is provided between the cartridge and the holder, since the reverse rotation is prohibited, there is an advantage that the user does not perform an unnecessary operation. Since the liquid cosmetic cartridge of the present invention itself has the applicator, the applicator is replaced every time the cartridge is replaced, which is sanitary and does not mix other colors with the applicator. Even during use, you can change the color of the contents with the same holder by changing the cartridge. Furthermore, the rotary extrusion piston type cartridge of the present invention has a feature that it can be used as an airtight stick-shaped cosmetic material feeding container by filling the solid cosmetic material with the application body removed.
