The stick-shaped cosmetic 3 gripped by the core chuck 4 is protruded/retracted by a feeding mechanism 9 in a shaft cylinder 8, so that impact is not directly transmitted to the grip portion of the core chuck. A gap is directly formed among the stick-shaped cosmetic and the grip portion of the core chuck, and the inner wall surface of a through-hole of the cartridge cylinder, so that the stick-shaped cosmetic is smoothly and reliably protruded/retracted without contacting the inner wall surface of the through-hole and without generating breakage or friction. Further, the grip portion of the core chuck is twisted to increase the inner diameter, and in such a state, air is sucked to readily and reliably grip the stick-shaped cosmetic at the core chuck. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

The present invention relates to a bar-shaped cosmetic container that accommodates a bar-shaped cosmetic such as a lipstick or an eyeliner, for example.

Conventionally, for example, a bar-shaped cosmetic container that accommodates a bar-shaped cosmetic such as a lipstick or an eyeliner in a retractable manner has a female threaded portion at the rear end of the front cylinder, and a protrusion of a push bar is used vertically in the container main body cylinder. In some cases, the engaging groove constitutes a rotation stopping mechanism, and the female thread portion and the protrusion of the push rod screwed into the female screw portion constitute a screwing mechanism. Therefore, by rotating the push rod and the tip tube with each other, the bar-shaped cosmetic material appears while rotating.

However, in the above-described stick-shaped cosmetic container, stick-shaped cosmetics such as lipstick and eyeliner held by the core chuck are flexible, so that they are easily deformed due to temperature changes and stress during application of the stick-shaped cosmetic. For this reason, when the deformed bar-shaped cosmetic is moved in and out of the front tube, the bar-shaped cosmetic held by the core chuck rotates while being eccentric. As a result, the bar-shaped cosmetic material comes into contact with the inner wall surface of the front tube, and the bar-shaped cosmetic material may be broken or worn.

Therefore, a tip cylinder having an opening hole at the tip, a container main body rotatably connected to the tip cylinder, and a cosmetic holding portion that is housed in the container main body and holds a stick-shaped cosmetic at the tip are formed. The push rod is moved in the axial direction by the rotation of the front tube and the container body, and the bar-shaped cosmetic material is caused to appear and disappear from the opening hole of the front tube, and is formed in the front tube. There has been proposed a stick-shaped cosmetic material feeding container in which the cosmetic holding portion at the tip of the push rod is formed into a spiral piece with respect to the spiral groove, and the cosmetic holding portion is accommodated in the spiral groove so as to freely advance and retract.

Japanese Patent No. 3441430

  In the stick-shaped cosmetic material feeding container of Patent Document 1, the cosmetic holding portion for holding the stick-shaped cosmetic is a screw-like piece, and the cosmetic holding portion is housed so as to be able to advance and retreat with respect to the spiral groove in the front tube. Has been. As a result, a space is formed between the bar-shaped cosmetic material that advances and retracts from the opening hole at the tip of the front tube and the inner peripheral surface of the front tube. As a result, even if deformation occurs in the bar-shaped cosmetic that advances and retreats from the opening hole of the front tube, the inner space between the bar-shaped cosmetic and the front tube depends on the interval formed between the bar-shaped cosmetic and the inner peripheral surface of the front tube. It is not in contact with the peripheral surface, and breakage and wear of the bar-shaped cosmetic material can be prevented.

However, when the cosmetic holding portion collides with the spiral groove in the front tube, the impact force is directly transmitted to the rod-shaped cosmetic through the cosmetic holding portion of the screw-like piece, and there is a possibility that deformation occurs.
When holding the bar-shaped cosmetic with respect to the cosmetic holding portion at the tip of the push rod, it must be inserted after the inner diameter of the elastic cosmetic holding portion that has once become a screw-like piece is enlarged. I must. For this reason, when the inner diameter of the cosmetic holding part is enlarged in order to hold the bar-shaped cosmetic, a large force against the elasticity of the cosmetic holding part is required. Moreover, in order to accurately hold the bar-shaped cosmetic, the bar-shaped cosmetic must be accurately inserted in the axial direction with respect to the deformed cosmetic holding portion. Therefore, it is very difficult to accurately insert the bar-shaped cosmetic while deforming the cosmetic holding portion which is a screw-like piece. As a result, workability in the manufacturing process is significantly reduced.

Therefore, the problems to be solved by the present invention are to allow a flexible bar-shaped cosmetic material that is easily deformed to stably appear and disappear, and to easily and surely hold the flexible bar-shaped cosmetic material on the core chuck.

First, as the first feature,

It is composed of a cartridge cylinder and a container body that is detachable from the cartridge cylinder,

One of the cartridge cylinders is equipped with a rod-shaped cosmetic, a core chuck and a spring for gripping the rod-shaped cosmetic,

The cartridge cylinder is provided with a bush at the rear end opening, and a plurality of helical female screw grooves are screwed on the inner wall surface of the through-hole penetrating the inside thereof.

The core chuck has a projecting portion that slidably fits in a plurality of spiral female screw grooves threaded on the inner wall surface of the through-hole, and projects in the base portion of the outer peripheral surface, and has a radial direction with elasticity. A grip portion made up of a plurality of spiral striates that expands and contracts, and a base portion that always comes into contact with the tip of a push rod described later,

A plurality of protrusions projecting from the base of the outer peripheral surface of a plurality of spiral filaments forming a gripping portion of a core chuck that grips a bar-shaped cosmetic with elasticity are screwed to the inner wall surface of the through hole of the cartridge cylinder And a spring between the base of the core chuck and the bush of the rear end opening of the cartridge cylinder that slidably fits in the spiral female screw groove and elastically grips the bar-shaped cosmetic at the grip Which can be stretched,

The other container body includes a coupling cylinder, a shaft cylinder, and a feeding mechanism inside the shaft cylinder,

The joint cylinder includes a holding part that holds the cartridge cylinder, and a fitting part that fits into a shaft cylinder to be described later.

The shaft cylinder is a cylinder that seals one end so as to incorporate a feeding mechanism therein.

The feeding mechanism advances and retracts a push bar that always contacts the base of the core chuck in accordance with the rotation of the shaft cylinder,

While incorporating a feeding mechanism in the shaft tube, and fitting the fitting portion of the joint tube to the shaft tube,

By rotating the shaft cylinder of the container body, the stick-shaped cosmetic is made to appear and disappear from the cartridge cylinder.

Therefore, based on the first feature, for example,

The feeding mechanism consists of a screw cylinder, push rod, groove cylinder and spring,

The screw cylinder is fixed in the shaft cylinder, and a spiral groove is screwed on the inner wall surface thereof.

The push bar is provided with a protrusion on the outer wall surface that loosely fits in the spiral groove of the screw cylinder,

The groove tube is provided with a guide groove for causing the protrusion of the push rod to advance straight in the axial direction between the screw tube and the push rod,

A groove tube is arranged on the outer periphery of the push rod, and a screw tube fixed inside the shaft tube is arranged on the outer periphery of the groove tube, and a spring is interposed between the push rod and the screw tube so as to be extendable and retractable. A protrusion projecting on the outer wall surface is slidably fitted in a spiral groove on the inner wall surface of the screw cylinder through the guide groove of the groove cylinder,

The push rod is advanced and retracted by rotating the shaft tube.

Therefore, when the cartridge cylinder and the shaft cylinder are mutually rotated and the push rod is advanced and retracted by the feeding mechanism, it protrudes from the base portion of the outer peripheral surface of the plurality of spiral filaments forming the grip portion of the core chuck for gripping the rod-shaped cosmetic. Since the protruding portion is loosely fitted into a plurality of helical female screw grooves that are screwed to the inner wall surface of the through hole of the cartridge cylinder, it rotates along the helical female screw groove of the through hole as the push bar advances and retreats. While advancing and retreating, the springs interposed between the bush of the opening of the cartridge cylinder and the base of the core chuck and between the push rod and the screw cylinder expand and contract, respectively. As a result, the bar-shaped cosmetic material appears and disappears from the tip of the cartridge cylinder due to the advance and retreat of the push bar and the elasticity of the expanding and contracting spring.

And since the protrusion is loosely fitted in the spiral female thread groove screwed on the inner wall surface of the through hole of the cartridge cylinder, the impact force is transmitted to the spiral filament that holds the bar-shaped cosmetic. Therefore, deformation and the like are less likely to occur in the stick-shaped cosmetic. In addition, the protruding portion of the core chuck is loosely fitted into the spiral female thread groove of the cartridge cylinder, so that the gripping portion of the core chuck, the rod-shaped cosmetic material gripped by the gripping section, and the inner wall surface of the through hole of the cartridge cylinder A gap is formed between the two. As a result, even if the bar-shaped cosmetic material gripped by the gripping portion of the core chuck is deformed by its own weight or heat, the gripping portion of the core chuck, the bar-shaped cosmetic material gripped by the gripping portion, and the through hole of the cartridge cylinder Even if the bar-shaped cosmetic is deformed by a gap formed between the inner wall and the inner wall, it does not come into contact with the inner wall of the through hole, and breakage and wear of the bar-shaped cosmetic can be prevented.

Further, in the manufacturing process of the cartridge cylinder, when the core cosmetic is gripped by the core chuck, a plurality of core chuck gripping portions are formed with respect to the spiral female thread groove screwed on the inner wall surface of the through hole of the cartridge cylinder. While engaging the helical striations, restraining relative movement in the axial direction of the cartridge cylinder and twisting it in the direction opposite to the spiral winding direction of the spiral female thread groove expands its inner diameter, further sucking air By doing so, the bar-shaped cosmetic is accommodated in the grip portion of the core chuck whose center is expanded. Then, by eliminating the twist that expands the inner diameter of the gripping portion of the core chuck, the rod-shaped cosmetic is easily and reliably gripped by the plurality of spiral filaments forming the gripping portion of the core chuck.

And as a second feature, based on the first feature,

In the plurality of spiral linear bodies constituting the gripping portion of the core chuck, a rod-shaped cosmetic slip-off preventing rib that protrudes along the inner surface of each spiral linear body is projected and formed. It is.

Therefore, the rod-shaped cosmetic removal prevention rib formed along the inner surface of the plurality of spiral linear bodies forming the gripping portion of the core chuck is based on the elasticity of the plurality of spiral linear bodies forming the gripping portion of the core chuck. It will bite into the surface of the rod-shaped cosmetic material held by the spiral striatum. As a result, even if the bar-shaped cosmetic is pulled in the axial direction, it is securely gripped in the gripping portion of the core chuck by the bar-shaped cosmetic slip-off preventing rib that firmly bites into the surface of the bar-shaped cosmetic and can be pulled out from the core chuck. Can be prevented.

Furthermore, as a third feature, based on the first and second features,

In the plurality of spiral filaments constituting the gripping portion of the core chuck, a stopper that protrudes from the end of the rod-shaped cosmetic material is formed in the vicinity of the inner bottom of the inner surface of each spiral filament. is there.

Therefore, the end portion of the bar-shaped cosmetic material held in the holding portion of the core chuck comes into contact with the stopper to be integrated. Therefore, even if a pressing force in the axial direction is applied to the bar-shaped cosmetic, it does not move further in the axial direction in the gripping portion of the core chuck. As a result, there is no need to expand the spiral filaments from the base by the stopper, that is, the minimum expansion is sufficient to hold the bar-shaped cosmetic material, and the bar-shaped cosmetic material can be held uniformly.

The invention of the present application prevents breakage and wear of a flexible bar-shaped cosmetic material, allows it to appear smoothly and reliably from the cartridge cylinder, and allows the bar-shaped cosmetic material to be easily and reliably held with respect to the core chuck in the manufacturing process. It has the outstanding effect that an improvement in property can be aimed at.

Reference numeral 1 shown in FIGS. 1 to 6 is a stick-shaped cosmetic container which is an embodiment of the present invention. The bar-shaped cosmetic container 1 is composed of a cartridge cylinder 2 and a container body 6 from which the cartridge cylinder 2 can be freely attached and detached.

First, one of the cartridge cylinders 2 is for mounting a flexible stick-shaped cosmetic 3 such as lipstick or eyeliner, a core chuck 4 for gripping the stick-shaped cosmetic 3 and a spring 5.

The cartridge cylinder 2 is provided with a bush 2b in the rear end opening 2a and a through hole 2c penetrating through the inside, and three spiral female screw grooves 2d are formed on the inner wall surface of the through hole 2c. It is made by screwing.

The core chuck 4 has a protruding portion 4f slidably fitted in three spiral female screw grooves 2d screwed on the inner wall surface of the through hole 2c of the cartridge cylinder 2 at the base portion of the outer peripheral surface thereof. At the same time, it comprises a gripping portion 4b composed of three spiral filaments 4a that expand and contract in the radial direction with elasticity, and a base portion 4c that always comes into contact with the tip of a push rod 11 described later.

Therefore, in the cartridge cylinder 2, the protrusion 4 f that protrudes from the base of the outer peripheral surface of the three spiral filaments 4 a that form the grip 4 b of the core chuck 4 is formed on the inner wall surface of the through hole 2 c of the cartridge cylinder 2. The spring 5 is slidably fitted into the three spiral female screw grooves 2d that are screwed, and between the base 4c of the core chuck 4 and the bush 2b of the rear end opening 2a of the cartridge cylinder 2. Is inserted in a telescopic manner.

Next, the other container body 6 has a joint cylinder 7, a shaft cylinder 8, and a feed mechanism 9 inside the shaft cylinder 8.

The joint cylinder 7 includes a holding portion 7a that holds the cartridge cylinder 2 and a fitting portion 7b that fits into a shaft cylinder 8 to be described later.

The shaft cylinder 8 has a cylindrical shape so that a later-described feeding mechanism 9 can be incorporated.

The feeding mechanism 9 includes a screw cylinder 10, a push rod 11, a groove cylinder 12 and a spring 13.

The screw cylinder 10 is fixed in the shaft cylinder 8 and has a spiral groove 10a screwed on the inner wall surface thereof.

The push bar 11 is provided with a protrusion 11 a that is loosely fitted in the spiral groove 10 a of the screw cylinder 10 on the outer wall surface.

The groove tube 12 is provided with a guide groove 12a between the screw tube 10 and the push rod 11 for causing the protrusion 11a of the push rod 11 to advance straight in the axial direction.

Therefore, in the container body 6, the groove tube 12 is disposed on the outer periphery of the push rod 11, and the screw tube 10 that is fixed inside the shaft tube 8 is disposed on the outer periphery of the groove tube 12, and the rear end of the screw tube 10 and the push rod 11. With a spring 13 interposed between the rear end and the rear end, a protrusion 11a projecting from the outer wall surface of the push rod 11 passes through the guide groove 12a of the groove tube 12 into the spiral groove 10a on the inner wall surface of the screw tube 10. It is loosely slidably fitted.

As described above, the cartridge cylinder 2 and the container main body 6 are configured, and the cartridge cylinder 2 and the container main body 6 are rotatably integrated into a stick-shaped cosmetic container 1 that is an embodiment of the present invention.

First, the push rod 11 is advanced and retracted by the feeding mechanism 9 housed in the shaft cylinder 8 of the container body 6 by rotating the shaft cylinder 8 forming the container body 6. Then, while the spring 13 is expanded and contracted by the advancement and retraction of the push rod 11, the spring 5 is advanced and retracted while extending and retracting in the core chuck 4 with which the tip of the push rod 11 abuts. As a result, the bar-shaped cosmetic 3 held by the core chuck 4c appears and disappears from the cartridge cylinder 2.

Further, in the three spiral filaments 4a forming the gripping portion 4b of the core chuck 4, the rod-shaped cosmetic slip-off preventing ribs 4d engaged with the rod-shaped cosmetics 3 along the inner surface of each spiral filament 4a. Is formed to protrude.

Further, in the three spiral filaments 4a constituting the gripping part 4b of the core chuck 4, a stopper 4e with which the end of the bar-shaped cosmetic material 3 abuts in the vicinity of the inner bottom of the inner surface of each spiral filament 4a. Projecting.

In addition, a rear opening 8a is formed at the rear end of the shaft cylinder 8 constituting the container body 6, and a cap 14a, a brush 14b, and a brush holder 14c for fixing the brush 14b to the rear opening 8a. The brush cartridge body 14 is inserted and secured.

Since the stick-shaped cosmetic container 1 which is an embodiment of the present invention has the above-described configuration, the user uses it as follows.

That is, when projecting the bar-shaped cosmetic 3 from the bar-shaped cosmetic container 1, the user grips the cartridge cylinder 2 and rotates the shaft cylinder 8 forming the container body 6. Therefore, by the rotation of the shaft tube 8, the screw tube 10 fixed in the shaft tube 8 rotates together with the shaft tube 8, and advances straight in the axial direction of the groove tube 12 in the spiral groove 10 a on the inner wall surface of the screw tube 10. A protrusion 11a protruding from the outer wall surface of the push bar 11 through the guide groove 12a is slidably fitted. As a result, in the container main body 6, the push bar 11 moves forward in the groove cylinder 12 while extending the spring 13 interposed between the push bar 11 and the screw cylinder 10. The push rod 11 that moves forward in the container main body 6 presses the rear end of the base portion 4c that forms the core chuck 4 with which the front end abuts. Further, since the push rod 11 pushes the spring 5 interposed between the base portion 4c of the core chuck 4 and the bush 2b of the rear end opening 2a of the cartridge cylinder 2, the gripping portion of the core chuck 4 is pressed. The protrusion 4f protruding from the base of the outer peripheral surface of the three spiral linear bodies 4a forming 4b rotates along the helical female screw groove 2d screwed to the inner wall surface of the through hole 2c of the cartridge cylinder 2. While moving forward. Therefore, the bar-shaped cosmetic 3 held by the lead chuck 4 protrudes from the opening 2c of the cartridge cylinder 2 as the lead chuck 4 advances.

Then, after the bar-shaped cosmetic 3 is applied, the bar-shaped cosmetic container 1 is reversed, the cap 14a of the brush cartridge body 14 is removed, and the applied bar-shaped cosmetic 3 is applied by the brush 14b held by the brush holder 14c. It can be adjusted appropriately.

Even if it is intended to pull out the bar-shaped cosmetic 3 protruding from the cartridge cylinder 2 in this way, it engages with the bar-shaped cosmetic 3 disposed along the inner surface of the three spiral filaments 4 a of the core chuck 4. The stick-shaped cosmetic 3 is securely held by the stick-shaped cosmetic slip-off preventing rib 4d. As a result, it is possible to prevent the stick-shaped cosmetic 3 that is more flexible than the stick-shaped cosmetic container 1 from dropping off.

In addition, three spiral female screw grooves in which protrusions 4f projecting from the base of the outer peripheral surface of the three spiral filaments 4a of the core chuck 4 are screwed to the inner wall surface of the through hole 2c of the cartridge cylinder 2 are provided. It is as follows by loosely fitting each 2d. That is,

First, since the impact force is hardly transmitted directly to the three spiral filaments 4a that hold the stick-shaped cosmetic 3, the stick-shaped cosmetic 3 is not easily deformed.

In addition, a gap is formed between the three spiral filaments 4 a forming the grip portion 4 b of the core chuck 4 and the inner wall surface of the through hole 2 c of the cartridge cylinder 2. As a result, the core chuck 4 does not come into contact with the inner wall surface of the through-hole 2c, and deformation and breakage of the bar-shaped cosmetic material 3 held by the core chuck 4 can be prevented.

Further, in the three spiral filaments 4a constituting the gripping portion 4b of the core chuck 4, the stopper 4e is formed in the vicinity of the inner bottom of the inner surface of each spiral filament 4a. These end portions come into contact with and become integral with the core chuck 4. As a result, it is not necessary to expand the three spiral filaments 4a from the root by the stopper 4e, that is, it is sufficient to expand the minimum amount, and the bar-shaped cosmetic 3 can be held uniformly. .

In addition, after use, the shaft 8 of the container body 6 is rotated in the opposite direction, so that the push bar 11 moves backward in the screw cylinder 10 and the spring 13 that has been extended when the bar-shaped cosmetic 3 is projected is compressed. . As a result, the core chuck 4 retreats while rotating along the spiral female screw groove 2d screwed on the inner wall surface of the through hole 2c of the cartridge cylinder 2 and compressing the spring 5, so that the core chuck 4 The bar-shaped cosmetic 3 held by the holding portion 4b is immersed in the cartridge cylinder 2.

Note that the gripping portion 4b of the core chuck 4 grips the stick-shaped cosmetic 3 as shown in FIG. That is, the core chuck 4 is inserted from the rear end of the cartridge cylinder 2 and engaged with the helical female screw groove 2d screwed on the inner wall surface of the through hole 2c, and the cartridge cylinder 2 is relatively moved in the axial direction. By restraining and twisting in the direction opposite to the spiral winding direction of the spiral female screw groove 2d, the inner diameter of the three spiral filaments 4a forming the gripping portion 4b of the core chuck 4 is expanded. Air suction from the rear direction of the cartridge cylinder 2 generates a suction force into the through hole 2c at the front end opening 2e of the cartridge cylinder 2. As a result, the bar-shaped cosmetic 3 sucked from the front end opening 2e of the cartridge cylinder 2 is loaded through the through hole 2c in the cartridge cylinder 2 until it comes into contact with the stopper 4e in the grip portion 4b of the core chuck 4. . After that, by releasing the twisting of the three spiral filaments 4a of the core chuck 4, the inner diameter of the three spiral filaments 4a of the core chuck 4 is reduced and the rod-shaped cosmetic is surely obtained. 3 will be held.

The present invention makes it possible to smoothly and surely make flexible stick-shaped cosmetics such as lipsticks and eyeliners appear and disappear, and to make the stick-shaped cosmetics easily gripped by the core chuck. The present invention can be widely applied to containers that can be freely stored.
