Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a stick-shaped cosmetic dispensing container.

"Prior art" The conventional stick-shaped cosmetic feeding container used conventionally is
The lower end of the main cylinder is used as a knob, and the upper cylinder of the knob is used as a guide tube, and split grooves are provided vertically on both left and right sides of the guide tube, and a female screw tube is rotatable on the outer surface of the guide tube. From the left and right side surfaces of the bottom fitting fitting tray of the rod-shaped cosmetic product that is fitted and further fitted into the guide cylinder, a pin that engages the tip of the thread groove of the female screw cylinder through the split groove is formed. By holding the female screw cylinder and rotating the knob cylinder in both the forward and reverse directions, the stick-shaped cosmetic product was taken in and out through the saucer.

"Problems to be solved by the invention" In the conventional screw-type feeding container, since the tray is screwed up and down, for example, the tray moves vertically as compared with the distance that the pin protruding from the peripheral wall of the tray slides along the screw groove. The distance, that is, the lead, becomes extremely short. Further, since the spiral groove has a circular shape in a plane, the container and the stick-shaped lipstick also have a circular cross section, and thus the shape of the container is limited. Further, the tip of the pin protruding from the outer surface of the pan peripheral wall slides in the thread groove, so that there is a drawback that so-called flapping is likely to occur when the cosmetic stick is vertically moved due to the gap between the inner surface of the thread groove and the outer surface of the pin tip.

The present invention eliminates the above-mentioned drawbacks by moving the stick-shaped cosmetic fitting and receiving tray up and down by liquid pressure.

"Means for Solving the Problem" A main cylinder 1 in which a bottom plate 5 is provided laterally between a cylinder 2 provided in the lower part of a cylinder and a lower end of a guide cylinder 3 formed by the cylinder upper cylinder part.
A tray 9 for fitting a rod-like cosmetic which is vertically movably fitted in the guide cylinder, a cylinder upper end portion with a closed upper end surface on the lower surface of the tray, and a cylinder lower end portion on the upper surface of the bottom plate 5 respectively. At the same time, a bellows cylinder 11 of a small diameter cylindrical hole that communicates the cylindrical hole with the small through hole 4 formed in the bottom plate, and a piston 18 from the lower end of the peripheral wall 16 fitted to the outer surface of the lower end of the main cylinder. A piston for the cylinder 2 having a knob cylinder member 15 which is upright and fits the piston into the cylinder.
A pressurized liquid that expands and contracts the bellows tube 11 by the vertical movement of 18 was filled in each of the cylinder and the bellows tube hole.

[Operation] The first embodiment will be described with reference to the first embodiment shown in FIGS. 1 and 2.
When the cap 25 is removed from the state shown in the figure and the knob cylinder member 15 is pushed up against the guide cylinder 3, the liquid inside the cylinder 2 is pushed into the bellows cylinder hole by the piston 18 rising. Since the bellows cylinder hole has an extremely small inner diameter with respect to the cylinder inner diameter, the liquid pressure causes the bellows cylinder to extend upward as shown in FIG.
Push up. The liquid is sucked back into the cylinder chamber by pulling back the knob member 15 and the negative pressure is applied to the bellows cylinder 11.
Contracts and the tray 9 also returns to the position shown in FIG. However, the above is the case of moving the saucer up and down from the lower limit to the upper limit,
When the stick-shaped cosmetic 8 is fitted in the saucer and moved up and down by the consumer, the upper end of the stick-shaped cosmetic 8 only needs to be slightly moved in and out from the upper end of the guide cylinder, so that the vertical movement of the knob member is only slightly performed. Is enough.

[Example] The present invention feeding container has a main cylinder, a rod-shaped cosmetic fitting and receiving tray, a bellows cylinder, and a knob cylinder member.

The first embodiment shown in FIG. 1 and FIG. 2 will be described. In the main cylinder 1, the lower portion of the cylinder body is the cylinder 2, and the cylinder upper cylinder portion is the guide cylinder 3, and the cylinder 2 and the guide cylinder are shown. And a bottom plate 5 with a small through hole 4 between them. The small through hole may be formed at the center of the bottom plate, and the first fitting cylinder 6 may be erected from the upper edge of the small through hole. Engaging ridges 7 on the outer circumference of the lower end of the cylinder
Is attached.

A receiving tray 9 for fitting the lower end of the rod-shaped cosmetic 8 is fitted into the guide tube 3 so as to be vertically movable. A fitting 10 is vertically provided from the center of the lower surface of the saucer bottom plate.

Between the bottom plate 5 and the tray 9, there is a bellows tube 11 with a closed upper end and a small diameter cylindrical hole, the upper end of which is the lower surface of the tray and the lower end is the small through hole 4 and the tube hole of the bellows tube. Are communicated with each other and fixed to the upper surface of the bottom plate 5, respectively. The second and third fitting cylinders 12 and 13 are respectively projected from the upper and lower ends of the bellows cylinder 11 and the fitting cylinders are fitted to the above-described fitting element 10 and the first fitting cylinder 6 to facilitate the operation. Can be fixed.

The knob cylinder member 15 has a peripheral wall 16 fitted to the lower outer surface of the main cylinder so as to be vertically movable, and a piston 18 is erected from a bottom plate 17 of the peripheral wall, and the piston is fitted into the cylinder 2. I am letting you. In order to prevent the main cylinder 1 from being pulled out downward, a downward step 19 that can engage with the engaging projection 7 on the outer periphery of the lower end of the cylinder 2 may be formed on the inner surface of the intermediate portion of the peripheral wall 16. piston
A piston ring 20 is fitted on the outer circumference of the upper end of 18. The position of the piston 18 in the cylinder 2 is determined so that the volume of the cylinder chamber space when the piston is located at the lower limit is the same as or larger than the volume inside the cylinder hole when the bellows cylinder 11 is extended. .

The pressurizing liquid is filled in the cylinder chamber and the tube hole of the bellows tube. The liquid injection can be done with a syringe.

The knob barrel member 15 may be formed as shown in FIG. In the embodiment, the piston is provided so as to move up and down with respect to the cylinder 2 when the peripheral wall 16 is rotated in both forward and reverse directions with respect to the main cylinder 1, and the extension cylinder 25 is hung from the lower end of the cylinder of the main cylinder 1, The peripheral wall 16 of the knob cylinder member 15 is rotatably fitted to the outer surface of the extension cylinder. Further, the lower end tube portion is fitted to the inner surface of the lower end portion of the peripheral wall 16, and screws 31, 31 are attached to both left and right portions of the upper end outer edge of the engaging cylinder 30 standing upright through a plurality of steps, and the screw is attached to the piston 18 peripheral wall. The projections 32, 32 attached to the outer peripheral surface of the lower end of the piston peripheral wall are engaged with the spiral groove of the inner surface of the extension cylinder 25 so as to be vertically movable to the inner surfaces of the vertical grooves 33, 33 of the extension cylinder 25. The ridge 34 circumferentially provided on the outer edge of the upper step portion is rotatably engaged with the concave groove circumferentially provided on the inner surface of the lower end of the. A liquid injection hole into the cylinder 30 or the like is provided on the top plate of the piston 18, and the hole is plugged.
It is sealed with.

[Advantage of the Invention] The present invention is configured as described above, and the liquid in the cylinder chamber enters and leaves the bellows tube through the operation of the knob tube member 15 with respect to the main tube 1 to expand and contract the bellows tube. Since it is provided so as to move up and down, there is the convenience that the saucer 9 can be moved up and down greatly by only slightly operating the knob cylinder.
Further, since the bellows tube 11 is greatly expanded and contracted and the length when contracted can be made extremely short, the entire length of the container can be made relatively short, and the piston is moved up and down to move the saucer up and down. Since the saucer is not screwed, the shape of the container cross section can be any shape, and the container design can be freely selected. The gap between the groove and the pin prevents the cosmetic stick from flapping.
