Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a dispensing container for storing fragile solid cosmetics and the like.

``Problems to be solved by conventional technology and inventions'' Dispensing containers with spiral elevating means on the cylindrical body are well known as stick-shaped cosmetic containers such as lipsticks. In addition, there was a desire to store various fragile solid cosmetics, such as compacted powders, that would crumble if strong force or shock was applied while carrying them, and in 1972 the Jiko Kosei was equipped with a cushioning mechanism. −38097 Publication, Kimiaki Sane
57-38098 and the like have been developed.

These products have a support stand erected inside the screw tube, a rotatable buffer seat for the solid cosmetics is equipped at the upper end of the support stand, and an outer layer for protecting the solid cosmetics is installed inside the screw tube. The cylinders are screwed together at their lower ends so that they can be screwed in and out, and a split storage cylinder for solid cosmetics is connected to the inside of the outer cylinder via a buffer member, and the buffer seat is attached to the storage cylinder. Furthermore, a solid cosmetic cushioning means is provided inside the cap that is detachably attached to the screw tube, and the solid cosmetic is accommodated in the raised split housing cylinder to cushion the bottom surface of the cap. It is seated on a catch and its upper surface is brought into contact with the buffer means inside the cap. When the solid cosmetic is to be used, the cap is removed and the screw tube is screwed to dispense the solid cosmetic from the slotted storage cylinder.

However, the split housing cylinder is made of metal or hard synthetic resin, and it is difficult to bring it into proper pressure contact with the solid cosmetic. Therefore, a gap is likely to occur between the split storage tube and the solid cosmetic, and if a gap occurs, the solid cosmetic will dance inside the split storage tube when carried, etc., and the external force will be absorbed by the buffer member. However, it may collapse due to this internal cause.

In addition, since the screw tube and the outer tube are directly screwed together, the screwed part has the largest diameter, and the screwing operation becomes direct and heavy. There is a drawback that spilled powder and dust from the outside enter and become trapped, causing stiffness in the threaded portion.

The present invention seeks to eliminate these drawbacks.

"Means for Solving the Problem" In order to achieve the above object, the present invention has a screw rod 2 erected inside the base tube 1, and a rotatable buffer seat for solid cosmetics on the upper end of the screw rod. equip it,
Moreover, a housing cylinder 3 made of a soft material is arranged above the screw rod so as to be insertable between the screw rod and the base cylinder 1, and a thread 10 is provided on the inner periphery of the lower end portion 14 of the housing cylinder. The housing cylinder 3 has U-shaped notches 11 which are screwed into the threaded rod 2 so as to be descendable, and which start at the lower part, reach the upper part, and fold back to the lower part at multiple locations on the outer peripheral surface of the housing cylinder 3.
, and form elastic pieces 12 on the inside of the cut, grooves 13 on the same level are formed on the outer surface of the upper end of these elastic pieces 12, and O-rings are inserted into these grooves. 15 to urge each elasticity inward, and an outer cylinder 4 is provided outside the housing cylinder 3 with an appropriate space 6 in between and insertable into the base cylinder 1. , the lower end of the outer cylinder is fixed to the lower end 14 of the storage cylinder, a cap 5 is detachably attached to the outer cylinder 4 to the base cylinder 1, and the solid makeup stored in the storage cylinder 3 is attached to the inner upper part of the cap. It is characterized by having a buffer means for bringing the top surface of the material into contact with the material.

"Function" With the above configuration, the brittle solid cosmetic A is stored in the storage tube 3, but the solid cosmetic is preformed with the outer periphery and height matching the inner periphery and height of the storage tube 3. Then, once the cap 5 is removed, the base cylinder 1 is inserted from above into the housing cylinder 3 with the base cylinder 1 sufficiently lowered to the lower limit, and is seated on the shock absorbing seat.

When applying makeup, remove the cap 5, support the outer cylinder 4, and spirally raise the base cylinder 1.
The upper part of the solid cosmetic A projects upward from the storage cylinder 3. In addition, if the base cylinder 1 is screwed down and the solid cosmetic A is pushed down lightly, the solid cosmetic A will be sunk into the storage cylinder 3 again.

By the way, the storage cylinder 3 made of soft material is used to store the solid cosmetic A.
The outer cylinder 4 protects the outer cylinder from external force on the outside, and even if the outer cylinder 4 is deformed by external force, the internal space 6 blocks the external force, and the outer cylinder 4 protects the housing cylinder 3 from the external force. prevent it from happening.

Furthermore, the plurality of elastic pieces 12... are urged inward by the O-rings 15 hooked on the grooves 13..., are appropriately pressed against the contained solid cosmetic A, and restrain the solid cosmetic A, To prevent solid cosmetic A from dancing.

"Example" The drawings show an embodiment of the invention.

In the illustrated example, a screw rod 2 is raised up from the center of the bottom of a bottomed base cylinder 1, a fitting recess 7 with a circular cross section is provided at the center of the top surface of the screw rod, and a seat plate 8 is arranged on the top surface of the screw rod. and protruding the protrusion 9 from the center of the lower surface of the seat plate,
The protrusion is rotatably fitted into the fitting recess 7, and the seat plate 8
A foam packing 19 is placed on top to form a rotatable buffer seat for solid cosmetics.

Above the threaded rod 2, there is arranged a housing cylinder 3 made of a soft material, which has an inner diameter larger than this and an inner diameter smaller than the inner diameter of the base cylinder 1, and a narrow inward flange is provided on the inner periphery of the lower end of the housing cylinder. At the same time, a thread 10 is provided on the inward flange so that it is screwed into the threaded rod 2 so that it can descend, and the inward flange abuts against the peripheral edge of the seat plate 8 at its upper limit. It is designed to prevent it from falling out.

The housing cylinder 3 is provided with U-shaped notches 11 on its front, rear, left, and right sides that start at the bottom, reach the top, and fold back to the bottom again, and the inside of the cut is formed into an elastic piece 12. , grooves 13 are formed on the outer surfaces of the upper ends of these elastic pieces, and O-rings 15 are hung on these grooves to urge the elastic pieces 12 inward, and the lower ends The outer periphery of the portion 14 is formed to have a slightly larger diameter.

An outer cylinder 4 is provided outside the housing cylinder 3 with a suitable space 6 in between, the lower end of the outer cylinder is fitted and fixed to the lower end 14 of the housing cylinder 3, and the upper end is squeezed inward.

The base cylinder 1 has an upper end portion 16 formed with a small outer circumference and a cap 5 detachably fitted into the upper end portion 16. The cap is provided with an elastic ring 17 on the inner circumference of the upper portion. is removably fitted onto the upper outer periphery of the outer cylinder 4.

The cap 5 also has the elastic ring 1 on the inner surface of the top wall.
It has a foam packing 18 supported by 7, and provides a buffering means for bringing the foam packing into contact with the upper end of the storage cylinder 3 and bringing the upper surface of the solid cosmetic stored in the storage cylinder 3 into contact. .

The brittle solid cosmetic A, which has been suitably formed in advance, is accommodated in the housing cylinder 3 and placed on the foam packing 19 on the seat plate 8, and the elastic piece 12 of the housing cylinder 3 is placed on the circumferential surface. Press them together.

Therefore, when the cap 5 is removed, the outer cylinder 4 is held, and the housing cylinder 3 is screwed together, the housing cylinder 3 is lowered, and as the solid cosmetic A rotates with the housing cylinder 3, it protrudes. At this time, the seat plate 8 and the foam packing 19 also rotate with the screw movement, so that no undue force is applied to the solid cosmetic A.

"Effects of the invention" According to the invention, it is possible to store the brittle solid cosmetic A, and it is possible to arbitrarily dispense and immerse it, as well as to make the solid cosmetic A soft in the storage tube 3 made of soft material. While being supported, the housing cylinder 3
The plurality of elastic pieces 12... are urged inward by the O-rings 15 hooked on the grooves 13..., and are appropriately pressed against the contained solid cosmetic A, thereby restraining the solid cosmetic A. Since the solid cosmetic A is prevented from collapsing due to internal causes, it is possible to reliably prevent the solid cosmetic A from collapsing due to internal causes. Since the cylinder 4 absorbs and protects the external force that would be applied to the solid cosmetic A, it is possible to accurately prevent the solid cosmetic A from collapsing due to external force.

In addition, a small-diameter screw rod 2 that stands up inside the large-diameter base tube 1 and a screw thread 1 provided on the inner periphery of the lower end portion 14 of the housing tube.
0 are screwed together, so the base tube 1 and screw rod 2
Due to the difference in diameter, the screw operation force of the base tube 1 can be reduced dynamically, and even if powder spilled from solid cosmetics or dust from the outside enters, it will not directly enter the screw joint. There is no chance of getting caught, and there will be no discomfort at the threaded joint.
Therefore, the screw operation of the base cylinder 1 and the feeding out of the solid cosmetic A can be performed easily.
