Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a roll-up type container for stick-like cosmetics, and particularly relates to an improvement of a roll-up type container equipped with an inner lid for molding cosmetics.

<Prior Art> As shown in Japanese Utility Model Publication No. 56-19931, the present applicant previously attached an inner lid to the tip of a cylindrical container in a watertight manner, and filled the cylindrical container with cosmetics from the bottom. We have developed a roll-up type container in which the inner lid is molded into a stick shape as a mold for shaping the tip of the cosmetic. With this technology, compared to the conventional method of filling cosmetics from the tip of the container, there is no denting caused by the cooling of the cosmetics after molding, and furthermore, after filling the cosmetics, the inner lid can be used as a cosmetics protection cap. There are advantages that can be used.

<<Problems to be solved by the invention>> However, with this technology, the inner lid is stored in a lowered state within the container body, so it is difficult for the purchaser to check the color of the contents at the time of sale. had to be rounded up one by one.

In addition to the inconvenience of having to carefully remove the inner lid with your fingers when using the product, the vibrations caused by the vibrations caused by the vibrations caused by carrying the stick-like cosmetics after use and carrying them in the handbag are also a problem. There was a problem in that the material gradually rolled up and the tip came into contact with the inner top surface of the cap, causing damage.

The present invention was developed in view of the following problems, and its purpose is to be able to check the color of the contents in the folded state, and to prevent the unused state from being damaged due to mistakenly being carried forward. Furthermore, the present invention provides a flip-up container that can be locked to prevent unnecessary rotation after use.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a cylindrical saucer that integrally holds stick-like cosmetics and that can be raised and lowered by rotating a dial, and a cylindrical saucer that can be raised and lowered by rotating a dial, and the saucer. a middle cylinder that fits watertightly on the outer periphery of the dial and rotatably fits on the lower end of the dial to restrict its rise; The structure consists of an outer cylinder rotatably fitted around the periphery, and an inner lid elastically fitted in a watertight and removable manner to the outer periphery of the tip of the inner cylinder. A rotation guide groove is provided on either the outer circumference of the outer cylinder or the inner circumference of the dial to allow relative rotation in the circumferential direction, and a first guide protrusion that engages with the rotation guide groove is provided on the other side. and a lock groove that guides the first guide protrusion in the vertical direction perpendicular to the rotation guide groove, and extends in the same direction as the lock groove in either the inner cylinder or the outer cylinder. A guide groove is formed and a second guide protrusion is provided on the other side.

<<Function>> In an unused, folded-down state after being filled with cosmetics, the inner tube protrudes beyond the upper end of the outer tube, and the inner lid is elastically fitted into this protrusion. In this state, the first guide protrusion is engaged with the upper end of the lock groove, and the second guide protrusion is locked with the lower end of the guide groove from free rotation of the engaging dial.
When the outer cylinder is pulled out in the axial direction relative to the dial, the outer cylinder rises relative to the middle cylinder and the inner cover is automatically removed. When the dial is then rotated, the tray rises on the inner circumference of the inner cylinder, and the stick-shaped cosmetic is lifted up.

<<Example>> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, 1 is a liftable cylindrical container body;
Reference numeral 2 denotes a cylindrical cap that is removably fitted around the outer periphery of the container body.

The container body 1 includes a cylindrical saucer 3 that integrally holds a stick-like cosmetic S, a middle tube 4 that is fitted watertightly to the upper outer periphery of the saucer 3, and an outer tube that is fitted to the outer periphery of the middle tube 4. 5, a dial 6 rotatably fitted to the outer periphery of the bottom of the outer cylinder 5, a bottom plate 7 integrated to the bottom surface of the dial 6, and elastically fitted in a watertight and removable manner to the outer periphery of the tip of the middle cylinder 4. It consists of an inner lid 8 made of plastic.

The upper peripheral edge of the saucer 3 is integrally formed with a sealing portion 3a that slides into contact with the inner circumferential wall of the middle cylinder 4, and a nozzle cylinder 9 for filling cosmetics is provided at the center of the lower part of the saucer 3. The nozzle tube 9 is integrally formed in a protruding manner, and furthermore, a female threaded portion 10 is integrally formed on the inner peripheral wall of the outer peripheral portion of the nozzle cylinder 9, which faces the nozzle cylinder 9 through a concentric space.

A cylindrical part 12 having a male threaded part 11 formed on the outer periphery is provided at the upper center of the bottom plate 7, facing the female threaded part 10.
is integrally provided in a protruding manner, and the male threaded portion 11 is screwed into the female threaded portion 10. Further, a pair of guide protrusions 13, 13 are formed protrudingly on the outer periphery of the lower end of the saucer 3, and are guided vertically along a pair of guide grooves 14, 14 formed vertically in the lower part of the middle cylinder 4. It's becoming like that. Therefore saucer 3
moves up and down along the inner cylinder 4 as the dial 6 is rotated, allowing the cosmetic S to be moved up and down.

A flange 16 integrally protrudes from the lower outer periphery of the middle cylinder 4 and is rotatably held along a step 17 formed on the lower inner peripheral surface of the dial 6. Further, a pair of guide grooves 18, 18 are formed along the vertical direction on the upper outer periphery of the middle cylinder 4, and each guide groove 18 is formed by a guide protrusion protruding from the upper inner periphery of the outer cylinder 5. The inner cylinder 4 and the outer cylinder 5 are slidably fitted into the inner cylinder 19, and the inner cylinder 4 and the outer cylinder 5 are connected to each other by the engaged state of the two and the vertical regulation of the inner cylinder 4 by the dial 6.
and can be moved up and down relative to each other.

A circumferential rotation guide groove 20 is formed on the lower outer periphery of the outer cylinder 5, and a pair of lock grooves 21, 2 extending above the rotation guide groove 20 are formed.
1 is formed. Corresponding to the rotation guide groove 20 and the lock groove 21, a pair of guide protrusions 22, 22 protrude from the upper inner periphery of the dial 6.
The grooves 20 and 21 can be engaged with each other. When the guide protrusion 22 is fitted into the lock groove 21, the dial 6 cannot be rotated, and at the same time, the guide protrusion 19 of the outer cylinder 5 engages with the lower part of the guide groove 18 of the inner cylinder 4. relatively middle tube 4
The tip of the outer periphery 5 protrudes from the tip of the outer periphery 5.

Next, the operation of the dispensing type container having the above structure will be explained.

First, when filling the empty container body 1 with the cosmetic S, fit the inner lid 8 to the tip of the inner tube 4 in the locked state shown in FIG. 2a, and set it in the cosmetic filling mold. do. Next, by filling the space surrounded by the saucer 3, the inner tube 4, and the inner lid 8 with the cosmetic S through the nozzle tube 9, the stick-shaped cosmetic S is formed with a tip shaped according to the shape of the inner lid 8. can.

Since the inner lid 8 is made of a transparent plastic container, the color of the cosmetic S inside after molding is completed is the same as that of the inner lid 8.
You can view it directly through. Therefore, by covering the container body 1 with the cap 2 in the molded state, the product can be shipped as is, and when checking the color of the contents at a store, it can be checked simply by removing the cap 2.

Next, a case will be described in which the cosmetic S is fed out to the tip of the container body 1.

First, in the initial state, the guide protrusion 22 engages with the lock groove 21, the rotation of the dial 6 is locked, and the outer cylinder 5 is lower than the tip of the middle cylinder 4.
The inner lid 8 is elastically fitted to the tip of the cosmetic S to cover the protruding end of the tip of the cosmetic S.

If you want to dispense the cosmetic S from this state, hold the outer cylinder 5 with one hand, hold the dial 6 with the other hand, and pull the outer cylinder in the axial direction.
As shown in FIG.
By moving along the guide groove 18, the outer cylinder 5 rises relative to the middle cylinder, and the inner cover 8 fitted to the upper end of the middle cylinder 4 is pushed up and removed. At the same time, the guide protrusion 22 of the dial 6 comes out of the lock groove 21 and enters the rotation guide groove 20, making it rotatable.

Next, when the dial 6 is rotated with a finger, as shown in FIG. 3, the saucer 3 rises on the inner periphery of the middle cylinder 4 according to the screwing state of the male threaded part 11 and the female threaded part 10.
This allows the cosmetic S to be dispensed.

After use, turn dial 6 in the opposite direction to the above.
The cosmetic S is stored inside the container body 1. When the dial 6 is pressed in the stored state, the dial 6 is raised along the lock groove 21 due to the engagement between the lock groove 21 and the guide protrusion, and becomes in the locked state.

<Effects> As explained in detail in the above examples, the advance-type container of the present invention is configured to include a cylindrical tray that holds the stick-shaped cosmetic as a unit and that moves up and down by rotating a dial, a middle tube that fits watertightly around the outer periphery of the tray and has its lower end rotatably fitted to the dial to restrict its ascent, an outer tube that fits vertically around the outer periphery of the middle tube and is rotatably fitted around the inner periphery of the bottom of the dial, and an inner lid that fits watertightly and detachably and elastically around the outer periphery of the tip of the middle tube.
When in the lowered position, the inner lid elastically fits onto the tip of the inner cylinder.
When unused, it adheres closely to the cosmetics, allowing you to check the color of the contents without having to pull it open.

A rotation guide groove is provided on either the outer circumference of the outer cylinder or the inner circumference of the dial to allow relative rotation in the circumferential direction, and the other is provided with a first guide protrusion that engages with the rotation guide groove. , and forming a lock groove that guides the first guide protrusion in the vertical direction and perpendicular to the rotation guide groove, and forming a guide groove extending in the same direction as the lock groove in either the inner cylinder or the outer cylinder. At the same time, since a second guide protrusion is provided on the other side, the rotation of the dial is locked when not in use, and there is no possibility of inadvertently rotating the dial and detaching the inner lid. Also, when using it for the first time from an unused state, if you pull the outer cylinder in the axial direction against the dial, the outer cylinder will rise relative to the middle cylinder and the inner cover will automatically come off. Ru. and,
After use, if the dial is pushed up along the lock groove and the first guide protrusion is engaged with it, there is no risk that the cosmetic will be drawn out by vibrations that occur when the cosmetic is carried in a handbag.
