Description

The present invention relates to a stick-shaped cosmetic delivery container that retractably accommodates a stick-shaped cosmetic such as eyebrow, eyeliner, lip liner, lipstick or the like (hereinafter referred to as "rod-shaped cosmetic").

Usually, the container for housing the rod-like cosmetic material in a retractable manner has a cavity for holding the rod-like cosmetic material at one end and a male screw is provided on the outer surface thereof, and a male screw provided on the outer surface of the male rod. In some cases, a rod-like cosmetic material gripped by a cavity provided at one end of the push rod can be made to extend and retract into and from the container main body by a feeding mechanism comprising a female screw member having an inner surface with a helical groove engaged. Reference 1).

However, in recent years, more flexible rod-like cosmetics have been adopted to improve usability, and the container of the above-mentioned rod-like cosmetics has high application pressure at the time of use, vibration at the time of carrying, and impact at the time of dropping Since it is not possible to buffer input from the outside, etc., problems such as bending, core breakage and core deviation are likely to occur with respect to the rod-shaped cosmetic.

Therefore, in order to closely contact the outer peripheral surface of the rod-like object with the inner surface of the core cylinder, the rod-like material dissolved with the extrusion part is filled so that the problem of core breakage or core slippage does not occur due to external input. It has been proposed to cause the rod-like object to project by solidifying it and causing the push-out portion provided at the tip of the moving body to slide in the filling member (see Patent Document 2). Therefore, once the rod is advanced, the rod can not be retracted. Therefore, particularly if the rod is excessively protruded, the rod may be wasted.

Therefore, according to the present invention, the flexible rod-like cosmetic composition can absorb external application pressure such as high application pressure at the time of use, vibration at the time of carrying, impact at the time of dropping, etc. It is possible to prevent defects such as slippage and to allow the appearance of the rod-shaped cosmetic material to be smooth and eliminate waste.

The first feature is

Cap, feeding container main body detachably attachable to the cap, core cylinder held by the feeding container main body, and a space formed by the feeding container main body and the core cylinder A rod-shaped cosmetic material gripped by a chuck portion formed of a plurality of integrally formed claws is freely held in a protective cylinder and is integrally and axially penetrating the center of the axial cylinder (hereinafter referred to as "axis"). A rod-shaped cosmetic holding unit which can slide in the longitudinal direction, and a spring for holding the rod-shaped cosmetic holding unit from the front end and the rear end on the axis,

The delivery container main body and the core cylinder are held so as to be mutually rotatable,
The delivery container main body and the screw piece forming the rod-like cosmetic holding unit are restricted in rotation and held so as to be slidable in the longitudinal direction of the axis,

The core cylinder and the protective cylinder forming the stick-shaped cosmetic holding unit are restricted in rotation and held so as to be slidable in the longitudinal direction of the axis,

In the space, the rod-shaped cosmetic holding unit is biased by a spring so that one is compressed and the other is extended by sliding in the longitudinal direction of the axis.

Therefore, when applying the rod-like cosmetic, by rotating the feeding container main body while holding the core cylinder, the screw piece forming the rod-like cosmetic holding unit is rotated.

Then, when the screw piece is rotated, a pressing rod formed on an outer peripheral surface of a male screw portion engaged with a female screw portion formed on an inner peripheral surface of the screw piece is also rotated.

At this time, since the push rod is restricted from rotating with the protective cylinder and is slidable in the axial direction, the protective cylinder is restricted from rotation by the griped core cylinder, and the protective cylinder also restricts the rotation of the chuck of the push rod. Therefore, the chuck portion formed at the tip of the push rod in the protective cylinder is advanced in the tip direction on the axis.

As a result, since the rod-shaped cosmetic material held in the protective cylinder protrudes from the opening of the tip of the protective cylinder, it can be used for use.

On the other hand, after the application of the rod-shaped cosmetic, by holding the core cylinder and rotating the delivery container main body in the opposite direction, the screw piece forming the rod-shaped cosmetic holding unit also rotates in the same direction.

Then, when the screw piece is rotated, a pressing rod formed on an outer peripheral surface of a male screw portion engaged with a female screw portion formed on an inner peripheral surface of the screw piece is also rotated in the same direction.

At this time, the push rod is restricted from rotating with the protective cylinder and is axially slidable, but the protective cylinder is restricted from rotation by the griped core cylinder, and the protective cylinder restricts the rotation of the chuck of the push rod Therefore, the chuck portion formed at the tip of the push rod in the protective cylinder is retracted toward the rear end on the axis.

As a result, since the rod-shaped cosmetic held in the protective cylinder is inserted into the opening of the tip of the protective cylinder, it can be accommodated in the rod-like cosmetic delivery container.

Then, in the rod-shaped cosmetic holding unit, the protective cylinder and the pressing rod are restricted in rotation with respect to the protective cylinder, and the chuck portion for gripping one end of the rod-shaped cosmetic at the tip of the pressing rod is regulated to be slidable in the longitudinal direction of the axis. The screw piece and the push rod are integrated by meshing the female screw formed on the inner circumferential surface of the screw with the male screw formed on the outer circumferential surface of the male screw. ing.

Therefore, when the stick-shaped cosmetic delivery container is dropped and an impact is given, the stick-shaped cosmetic holding unit is slidable in the longitudinal direction on the axis with respect to the core cylinder and the delivery container main body. The cosmetic holding unit integrally slides in the longitudinal direction of the axis in the space formed by the core cylinder and the delivery container main body according to the falling direction, and attaches the rod-like cosmetic holding unit from one side of the axial line. At the same time as the biasing spring is compressed, the biasing spring is extended from the other on the axis.

As a result, the impact applied to the stick-shaped cosmetic delivery container is buffered by the compression and the extension of the two springs, so that defects such as detachment or breakage of the stick-shaped cosmetic held in the protective cylinder can be prevented. .

As a second feature, based on the first feature,

A stick-shaped cosmetic holding unit is formed, and volatile oil is blended in the stick-shaped cosmetic held by the chuck portion formed at the tip of the pressing rod in the protective cylinder.

Therefore, even if the rod-shaped cosmetic that makes up the rod-shaped cosmetic holding unit improves the adhesion and elongation of the cosmetic and is flexible so that the cosmetic can be applied easily, the rod-shaped cosmetic can be used as a rod-shaped cosmetic The rod-shaped cosmetic holding unit having the rod-shaped cosmetic material slides against the impact on the rod-shaped cosmetic delivery container while being able to smoothly appear and retract into the inside and the outside of the delivery container, and the shock is sufficiently buffered. It is possible to more reliably prevent defects such as slippage and breakage in the above.

As a third feature, based on the first to second features,

An elastic O-ring or the like is attached between the cap and the delivery container body.

Therefore, it is possible to reliably prevent the deterioration due to the evaporation of the volatile oil contained in the rod-like cosmetic as well as the effects of the first feature to the second feature.

The present invention is a rod-shaped cosmetic dispensing container, which enables appearance of the rod-shaped cosmetic to eliminate waste, and prevents the rod-shaped cosmetic even if high application pressure, vibration at the time of carrying, and impact at the time of dropping are given. The rod-shaped cosmetic holding unit slides integrally the space formed by the core cylinder and the delivery container main body in the longitudinal direction of the axis, and biases the rod-shaped cosmetic holding unit from the front end direction and the rear end direction on the axis Since it is buffered by compression and extension of the spring, it has an excellent effect of being able to prevent defects such as core loss and core breakage of the rod-like cosmetic.

It is comprised.

First, the cap 2 has the locking convex portion 2a around the inner peripheral surface in the opening direction, and the fitting cylinder 5 fixedly supported by the shaft cylinder 4 has the locking concave portion 5a in the outer peripheral surface in the opening direction. And the slide groove 5b is formed on the inner peripheral surface of the slide cylinder 5 in the longitudinal direction of the axis of the fitting cylinder 5.

Therefore, the cap 2 and the fitting cylinder 5 supported by the shaft cylinder 4 are circumferentially provided on the outer peripheral surface of the locking projection 2 a and the fitting cylinder 5 provided on the inner circumferential surface of the cap 2 in the opening direction. By fitting with the locking recess 5a to be provided, it is integrated, and the airtightness in the rod-like cosmetic dispensing container 1 is maintained.

The core cylinder 6 is provided with a slide groove 6a in the longitudinal direction of the axis on the inner peripheral surface thereof.

Furthermore, in the rod-shaped cosmetic holding unit D, the protective cylinder 9 has the slide protrusion 9a protruding in the longitudinal direction of the axis on the outer peripheral surface, and the guide groove 9b is grooved in the longitudinal direction of the axis on the inner peripheral surface. It is a thing.

The push rod 8 has an external thread 8b formed on the outer peripheral surface thereof, and has at its tip integrated a chuck 8a for gripping one end so that the rod-like cosmetic 10 can slide in the axial direction in the protective cylinder 9 It is formed in

In addition, the screw piece 7 has a slide projection 7a protruding from the outer peripheral surface in the longitudinal direction of the axis, and a female screw 7b is formed in front of the inner peripheral surface.

Accordingly, the screw cylinder 7, the push rod 8, the protective cylinder 9, and the rod cosmetic 10 forming the rod-shaped cosmetic holding unit D are the protective cylinder 9 and the push rod 8 on the inner peripheral surface of the protective cylinder 9 in the longitudinal direction of the axis. The rotation of the chuck portion 8a for gripping one end of the stick-shaped cosmetic 10 is regulated by the tip of the push rod 8 with respect to the grooved guide groove 8b, and the screw portion 8a is engaged so as to be slidable in the longitudinal direction of the axis The piece 7 and the push rod 8 are integrated by meshing the female screw portion 6 b formed on the inner peripheral surface of the screw piece 7 and the male screw portion 8 b formed on the outer peripheral surface of the push rod 8.

The rod-shaped cosmetic holding unit D is disposed between the rear end 5 b of the core cylinder 6 and the projecting edge 9 c of the protective cylinder 9, and the rear end 7 c of the screw piece 7 and the inner bottom 5 c of the fitting cylinder 5. The springs 10 and 11 are connected between them to urge and hold the rod-shaped cosmetic holding unit D.

Furthermore, with respect to the slide grooves 6 a and 5 b grooved in the inner peripheral surface of the core cylinder 6 and the inner peripheral surface of the fitting cylinder 5, the screw pieces 7 and the protective cylinder 9 forming the rod-shaped cosmetic holding unit D The slide protrusions 7a and 9a protruding from the outer peripheral surface are restricted in rotation and engaged so as to be slidable in the axial direction.

As described above, since the rod-shaped cosmetic delivery container 1 according to the embodiment of the present invention is configured, the application of the rod-shaped cosmetic 10 is as follows.

First, by holding the core cylinder 6 and rotating the shaft cylinder 4, the fitting cylinder 5 is also rotated together with the shaft cylinder 4. Therefore, the rod-like cosmetic holding unit D rotates integrally with the fitting cylinder 5. The screw piece 7 which also makes a turn.

Then, when the screw piece 7 is rotated, the push rod 8 formed on the outer peripheral surface of the male screw portion 8 b which meshes with the female screw portion 7 b formed on the inner peripheral surface of the screw piece 7 also rotates.

At this time, the chuck portion 8 a of the push rod 8 is restricted in rotation by the protective cylinder 9 and is axially slidable, and the rotation of the protective cylinder 9 is restricted by the gripped core cylinder 6. Since the rotation of the chuck 8a is also restricted, the chuck 8a formed at the tip of the push rod 8 in the guide groove 9b of the protective cylinder 9 advances in the axial tip direction.

As a result, since the rod-shaped cosmetic 10 held in the protective cylinder 9 protrudes from the opening of the tip of the protective cylinder 9, it can be used for use.

On the other hand, after use, the fitting cylinder 5 is integrally rotated in the same direction by holding the core cylinder 6 and then rotating the barrel 4 in the opposite direction. The screw piece 7 forming the rotating rod-like cosmetic holding unit D also rotates in the same direction.

Then, when the screw piece 7 is rotated, the push rod 8 formed on the outer peripheral surface of the male screw portion 8b which meshes with the female screw portion 7b formed on the inner peripheral surface of the screw piece 7 also rotates in the same direction. .

At this time, the chuck 8a of the push rod 8 is restricted in rotation with the protective cylinder 9 and is axially slidable, and the rotation of the protective cylinder 9 is restricted by the gripped core cylinder 6, and the protective rod 9 further Since the rotation of the chuck 8a is restricted, the chuck 8a formed at the tip of the push rod 8 in the guide groove 8b of the protective cylinder 9 is retracted in the axial direction.

As a result, the rod-shaped cosmetic 10 held in the protective cylinder 9 can be inserted into the rod-like cosmetic dispensing container 1 by being sunk from the opening of the tip of the protective cylinder 9.

Further, as described above, since the rod-shaped cosmetic 10 held in the protective cylinder 9 can be freely inserted into and withdrawn from the core cylinder 6, waste can be reliably prevented.

Furthermore, as described above, in the screw piece 7, the push rod 8, the protective cylinder 9, and the stick cosmetic 10 forming the rod-like cosmetic holding unit D, the protective cylinder 9 and the push rod 8 are axial lines on the inner peripheral surface of the protective cylinder 9. The rotation of the chuck 8a that holds one end of the stick-shaped cosmetic 10 at the tip of the push rod 8 is restricted with respect to the guide groove 9b grooved in the longitudinal direction of the shaft, and engaged so as to be slidable in the longitudinal direction of the axis The screw thread 7 and the push rod 8 are integrated by meshing the female screw portion 7b formed on the inner circumferential surface of the screw piece 7 and the male screw portion 8b formed on the outer circumferential surface of the push rod 8 .

Therefore, as shown in FIGS. 4 (a) to 4 (c), for example, when a shock due to a drop or the like is given to the rod-like cosmetic dispensing container 1 [see FIG. When it is dropped from [see the same figure (b)], the protective cylinder 9 forming the stick-shaped cosmetic holding unit D can slide in the axial direction with respect to the core cylinder 6, and the screw piece 7 Since the rod-like cosmetic holding unit D integrally slides in the space defined by the core cylinder 6 and the fitting cylinder 5 in the axial tip direction, the rear end portion of the core cylinder 6 6c and the projecting edge 9c of the protection cylinder 9 while compressing the spring 11 held between the rear end 7c of the screw piece 7 and the inner bottom 5c of the fitting cylinder 5 , Extends the held spring 12.
