Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispensing container for stick-shaped solid cosmetics such as lipstick and solid hairdressing, and more particularly to a dispensing container provided with a mechanism for preventing the saucer from returning.

[0002]

2. Description of the Related Art Conventionally, as an example of a container in which a bar-shaped solid cosmetic product stored is drawn out by a rotating operation, an outer cylinder having a spiral groove formed on the inner circumference thereof and a long sleeve rotatably inserted in the outer cylinder. A rotary cylinder having a hole and a lateral hole communicating with the base end thereof; and a saucer having an engaging protrusion movably inserted into the rotary cylinder and having an engaging protrusion engaged with a spiral groove through an elongated hole at an outer peripheral portion thereof. BACKGROUND ART A well-known delivery container is made up of a bar-shaped solid cosmetic product which is made of a material such that the rod-shaped solid cosmetic that is planted in a saucer is rotated in and out of the container by rotating the outer cylinder and the rotary cylinder.

However, in this conventional structure, when the cosmetics are taken in and stored, the engaging projections protruding from the outer side of the tray are guided by the spiral groove and the long hole, and the long hole is formed in the long hole. They were only guided by the lateral holes that were continuously provided, and did not particularly lock the engaging projections.

Therefore, in this conventional structure, the movement of the engaging projection guided to the lateral hole is regulated in the vertical direction, but the feeding container is originally designed to rotate smoothly in consideration of ease of use. Are formed and assembled. Therefore, if an external force such as vibration is applied when the cosmetics are transported upside down and the tray is loaded with its own weight, this force also acts on the rotation direction of the outer cylinder. Therefore, the outer cylinder will rotate naturally and the protrusion will come off the lateral groove.
Not only does cosmetics fall down along the long holes due to their own weight, the tips of the cosmetics come into contact with the ceiling surface of the lid and stain the inside of the lid, or the cosmetics are deformed or broken, which significantly reduces the commercial value. However, there are drawbacks such as giving the user a disadvantage that the cosmetics become defective.

As an improvement plan for eliminating such a defect, there is an invention described in Japanese Utility Model Publication No. 51-32615.
As shown in the explanatory view of FIG. 4, the present invention forms a holding portion 54 composed of a projection 53 or an inclined surface in a lateral hole 52 communicating with the long hole 51 in a feeding container having the above-mentioned known feeding mechanism. Engagement protrusion 55 at the sinking end position of the tray
Is fitted and held in the lateral hole 52.

In this feeding container, the engaging projection 55 is formed in the lateral hole 52.
Since it was held inside, it was possible to eliminate the occurrence of defective products due to natural feeding. However, in this feeding container, since the rotary cylinder is formed to be thin due to the mechanism of this type of feeding container, the thin portion has the elongated hole 51 and the lateral hole 52. When the rigid engaging projection 55 is guided by the lateral hole 52, gets over the projection 53, and fits into the holding portion 54, the rotary cylinder is easily deformed, and distortion due to the deformation remains on the rotary cylinder to prevent the container from rotating. It caused the lack of smoothness.

Further, since the projection 53 is also thin, the feeling of lightness when the engagement projection 55 gets over is poor, and the engagement projection 55 easily wears after repeated use, so that the engagement is maintained. There was a drawback that the function deteriorated rapidly.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and does not leave distortion in a thin-walled rotary cylinder, and at the start of feeding and at the end of feeding. An object of the present invention is to provide a stick-shaped solid cosmetic product dispensing container which is accompanied by a light sound repellency and a reliable feel, and which can surely prevent natural cosmetic product from being dispensed and maintain a stable stored state.

[0009]

An outer cylinder having a spiral groove formed on an inner circumference thereof, and a rotary cylinder having a long hole rotatably inserted in the outer cylinder and a lateral hole communicating with a base end thereof, In a feeding container having a tray which is movably inserted in the rotary cylinder and has an engaging protrusion formed on the outer peripheral portion to engage with the spiral groove through the elongated hole, in the spiral groove, substantially at the center of the width thereof. And a spherical projection is provided in the vicinity of a height position of a corner bending portion which is an upper opening end of the lateral hole to the elongated hole, and the engaging projection is provided with the spherical surface when the saucer is retracted. It is characterized in that the projection is passed over and is locked in the lateral hole, and the spherical projection serves as a stopper for preventing the natural extension of the tray.

[0010]

When the stick-shaped solid cosmetic product is taken in, the outer cylinder is grasped with fingers and the hakama fixed to the lower part of the rotary cylinder is pinched and rotated. Then, since the engaging protrusions protrudingly provided on the outer peripheral portion of the tray which is vertically movably inserted into the rotary cylinder engages with the spiral groove through the elongated hole, the engaging protrusion is guided by the spiral groove to be formed into the elongated hole. Go down along. Then, when it reaches the corner bending portion which is the upper opening end of the lateral hole communicating with the long hole, the spherical projection is provided substantially at the center of the width of the spiral groove and near the height position of the corner bending portion. The end surface of the engaging projection abuts on the engaging projection, and the engaging projection rides over the spherical projection to reach the base end of the elongated hole, and is further guided by the spiral groove to be locked in the lateral hole.

Since the engaging projection itself and the outer cylinder provided with the spiral groove are generally higher in rigidity than the receiving tray, the engaging projection rides over the spherical projection while flexing and elastically deforming the receiving tray.
Then, at the moment of overcoming the obstacle, the saucer returns elastically, emits a light sound and gives the user a reliable operating feeling. Since the spherical projection is located at the height on the horizontal line of the angled curved portion, that is, at the height facing the lateral hole, it serves as a stopper,
The engaging projection can be reliably locked in the lateral hole to prevent spontaneous extension.

When the rotary cylinder is rotated in the feeding direction opposite to the feeding direction, the engaging projection is guided by the spiral groove to reach the base end of the elongated hole from the lateral hole and to get over the spherical projection. It emits a light sound again and makes you feel that you have entered the feeding state with a certain operating feel.

There is. The upper end of one of the long holes 4 is opened in consideration of fitting of a receiving tray 7 to the outer cylinder 2 described later.

Further, a lower protrusion 13 having a flat upper surface is provided around the rotary cylinder 5 so as to be located below the elongated hole 4 and fitted in the hakama 11, and the lower protrusion 13 has a lower surface in the circumferential direction. Vertical ribs 14 are provided at appropriate intervals on the rotary cylinder 5 and
A bar-shaped protrusion 16 provided with a hook 15 for preventing the hakama 11 from coming off is provided at the center of the lower end of the.

The hakama 11 serves as a knob for rotating operation by being externally fitted and fixed to the lower part of the rotary cylinder 5, and a vertical rib 21 which is fitted to the vertical rib 14 is projected on the inner peripheral wall of the lower part. At the same time, a downward step 22 that engages with the hook 15 is provided at the center of the bottom.
A vertical hole 17 is formed in which the rod-shaped projection 16 is fitted in the vertical hole 17, and the hakama 11 and the rotary cylinder 5 are fixed to each other so that they cannot rotate and cannot be removed.

On the inner wall surface of the upper part of the hakama 11, an upward step portion 18 is provided so as to be located on the same horizontal plane as the upper surface of the lower protrusion 13, and the step portion 18 is provided on the outer cylinder 2 which will be described later. Is the seat that rotates.

The outer cylinder 2 has spiral grooves 1 and 1 formed on the inner wall surface thereof, and an upward step 19 is provided around the upper opening, and the upward step 19 is a ridge of the rotary cylinder 5. 12
It is abutted on the lower surface of and is rotatably fitted between it and the step portion 18 of the hakama 11.

Then, in the lower portion of the outer cylinder 2, in the spiral groove 1, 1 at the substantially center of its width, the lateral hole 3, mentioned above, is formed.
Spherical projections 9 and 9 having a diameter smaller than the spiral width and slightly protruding from the spiral bottom face each other at a facing position in the vicinity of a height position on the horizon of the corner curved portions 8 and 8 which are the upper opening ends of 3. Is formed (see FIG. 3).

A cylindrical tray 7 into which a rod-shaped solid cosmetic (not shown) is implanted has engaging projections 6 and 6 projecting from the outer surface of the peripheral wall. The engaging projections 6 and 6 are elongated holes 4 and 4, respectively. Is inserted into the spiral groove 1,1 and is slidably fitted into the spiral groove 1,1. It is fitted in the rotary cylinder 5 so as to be vertically movable.

The lid 10 is formed in a cap-shaped cylindrical body which is fitted onto the outer cylinder 2, and a notched annular rib 20 vertically provided in the top is inserted into the opening of the rotary cylinder 5 and elastically fitted. By fitting them together, the lid 10 is prevented from rattling.

When the cosmetics planted in the tray 7 of the feeding container of this embodiment as described above are to be stored in the container,
The outer cylinder 2 is gripped by fingers and the hakama 11 fixed to the lower part of the rotary cylinder 5 is picked up and rotated in the retracting direction, generally counterclockwise. Then, since the receiving projection 7 inserted in the rotary cylinder 5 so as to be vertically movable, the engaging projection 6 projectingly provided on the outer peripheral portion thereof engages with the spiral groove 1 through the long hole 4, It is guided and descends along the long hole 4.

When reaching the corner bent portion 8 which is the upper opening end of the lateral hole 3 communicating with the elongated hole 4, it is almost at the center of the width of the spiral groove 1 and the height position of the corner bent portion 8 on the horizontal line. The end surface 6a of the engaging projection 6 hits a spherical projection 9 provided in the vicinity of the spherical projection 9,
The engaging projection 6 rides over the spherical projection 9 to reach the base end of the elongated hole 4, and is guided by the spiral groove 1 to be locked in the lateral hole 3.

Since the engaging projection 6 itself and the outer cylinder 2 provided with the spiral groove 1 have higher rigidity than the receiving tray 7, the engaging projection 6 rides over the spherical projection 9 while flexing and elastically deforming the receiving tray 7. Then, at the moment when the saucer is elastically restored after riding over, it is recognized that the saucer has been housed due to the light sound repellency and the reliable operation feeling. Since the spherical projection 9 is located at the height on the horizontal line of the corner curved portion 8, that is, at the height facing the lateral hole 3, the engaging projection 6 is securely locked to the lateral hole 3 as a stopper, and the natural projection is naturally formed. Feeding out can be prevented.

At this time, the engaging projection 6 again springs back with a light sound repellency and a reliable operation feeling, and the user can visually confirm that he / she has entered the extended state.

As described above, the person who uses the dispensing container of the present embodiment can obtain a reliable feel with sound repellency both at the start of feeding and at the end of feeding, so that the cosmetic can be securely locked. Since it can be perceived that the cosmetic is stored in the position or separated from it, and therefore, even cosmetics which have become short by use can be stored and carried without visually confirming the storage position, there is no accidental natural feeding problem.

[0028]

As described above in detail, the delivery container of the present invention employs a well-known stable delivery mechanism,
Since it has a simple structure in which a spherical projection is provided at a predetermined position of the spiral groove, it can be provided at a low cost suitable for mass production, and since the spherical projection that serves as a stopper has almost no wear, it can withstand multiple uses. It is possible to reliably prevent the natural feeding of the saucer over a long period of time.

According to the structure of the feeding container of the present invention,
Since the thin rotating cylinder is not deformed, the rotating function is not impaired even if it is used many times, and the smoothness is not lost until the cosmetics are used up.

A person who uses the dispensing container of the present invention can obtain a reliable feel with sound repellency at the start of feeding and at the end of feeding, so that the cosmetic can be reliably stored in the locking position. You can store even cosmetics that are perceptible and have been shortened after use without visually confirming them, so you will not accidentally accidentally throw them out while carrying them.
