Description

[Detailed description of the invention] "Industrial Application Field" The present invention relates to a storage container for stick-shaped cosmetics that is suitable for storing stick-shaped cosmetics such as lipsticks, blushers, or lip balms in a manner that allows them to appear and disappear at will. It is.

``Prior Art'' This type of storage container is generally configured so that after the lid is removed from the main body, a part of the main body is relatively rotated to dispense the cosmetics, but the lid is separate from the main body. Because of this, there is the inconvenience of having to use cosmetics while holding the lid in your hand, or performing operations such as dispensing or storing cosmetics, and the risk of dropping the lid or losing powder. Problems often arose.

Therefore, as a container that takes such problems into consideration, a container shown in, for example, Japanese Utility Model Application Laid-Open No. 58-86019 has also been proposed.

This is done by forming a flat lid that covers the top opening of the container body, connecting it with a hinge to the edge of the top opening of the container body, and then moving the operation cylinder of the main body within a certain range in the vertical direction (in the axial direction of the main body). When dispensing cosmetics, the operation tube is slid upward and the lid is pushed up to open the lid, and then the operation tube is rotated. The structure is such that the cosmetics are dispensed by the user.

``Problem that the invention aims to solve'' If the cosmetics storage container is constructed in this way, the conventional inconvenience of having to put on and take off the lid each time you use cosmetics can be solved, but To operate the container when using the cosmetic, as mentioned above, first slide the operating barrel upward to open the lid, and from that state, rotate the operating barrel to dispense the cosmetic. Since the operation requires two different steps, the operation itself becomes complicated and has poor operability.Furthermore, if the operation tube is slid downward while the cosmetic is still being dispensed, the lid may be damaged. There were problems such as the risk of damaging the material by contacting it. In addition, it is naturally desirable for this type of storage container to have an excellent design, but it is desirable that the hinge connection part of the lid to the main body and the sliding part of the operation tube be exposed as they are on the outside. There was also the problem that this spoiled the appearance.

"Means for Solving the Problem" The present invention has a main body cylinder whose upper end is open and whose lower half is formed as a fitting cylinder part, and a spiral groove on the inner circumferential surface, and the fitting cylinder an operating tube rotatably mounted on the outside of the fitting tube around the axis of the fitting tube; a receiver for holding cosmetics inserted into the main body tube so as to be slidable in the vertical direction thereof; and an opening at the upper end of the main body tube. In the container, a long hole extending in the vertical direction is formed in the peripheral wall of the fitting cylinder part, and a sliding cylinder part that is slidable inside the fitting cylinder part is provided at the lower part of the saucer. A protrusion that fits into the spiral groove through the long hole of the fitting cylinder is provided on the outer peripheral surface of the sliding cylinder, and a guide hole extending vertically is formed in the outer wall of the main body cylinder. A protruding shaft that fits into the guide hole is provided on the outer surface of the saucer, and the lid has a leg plate that extends downward along the outer wall surface of the main cylinder, and the lower end of the leg plate is attached to the protruding shaft. The lid is pivotally attached to the lid so as to be vertically rotatable around the axis of the protrusion, and the lid is constructed to close the upper end opening of the main body cylinder when the saucer is at its lowest lowering position.

"Function" When the operation cylinder is rotated in the direction of feeding out the cosmetics, the saucer rises together with the cosmetics, but at this time, the lid that closes the top opening of the main body cylinder also moves upward in synchronization with the rise of the saucer. As a result, the upper end opening of the main body cylinder is opened, and the cosmetic material in the main body cylinder protrudes from there and is in a dispensed state. This action is achieved by making the protruding shaft of the saucer that moves up and down face the outer wall surface of the main cylinder, and by pivoting the lower end of the leg plate of the lid to this protruding shaft so that the lid can move up and down in synchronization with the saucer. Based on configuration. In addition, although the lid itself can be vertically rotated around the protruding axis of the saucer, the radius of rotation is determined by the structure in relation to the pivot position of the leg plate, rather than the maximum protrusion length of the cosmetic from the saucer. It has grown to
For this reason, the lid does not come into contact with cosmetics.

"Example" The example shown in FIGS. 1 to 4 shows an example in which the present invention is applied to a storage container in which the bar-shaped cosmetic A is a lipstick. In these figures, reference numeral 1 denotes a main body cylinder, and this main body cylinder 1 is formed in the shape of a square cylinder with an opening 2 at the upper end, and the lower half is formed as a cylindrical fitting cylinder part 3. A long hole 4 extending vertically (in the axial direction of the cylinder part 3) is formed in the peripheral wall of the fitting cylinder part 3.
Guide holes 5 extending in the vertical direction (axial direction) of the main body cylinder 1 are also formed in both outer wall surfaces.

Reference numeral 6 denotes an operation tube that is attached to the outside of the fitting tube 4 so as to be rotatable around the axis of the fitting tube 4, and a spiral groove 7 is formed on the inner peripheral surface of the operation tube 6. has been done. The operating tube 6 has a rectangular cylindrical outer shape that corresponds to the outer shape of the main body tube 1, and is designed so that the outer surfaces of the operating tube 6 are flush with each other when the operating tube 6 is installed, as shown in FIG. ing. As a means for preventing the operating barrel 6 from falling off, in the illustrated example, an annular groove 8 is formed on the lower inner circumferential surface of the operating barrel 6, and an annular protrusion 9 that fits into this annular groove 8 is formed on the lower outer circumferential surface of the operating barrel 6. It is said that it is a set configuration.

Reference numeral 10 denotes a tray for holding cosmetics that is slidably inserted into the main body tube 1 in the vertical direction. Sliding cylinder part 11 that can freely slide in the vertical direction
is provided. A protrusion 12 is provided on the lower outer circumferential surface of the sliding cylinder part 11 to fit into the spiral groove 7 of the operation cylinder 6 through the elongated hole 4 of the fitting cylinder part 3. Further, the outer surface of the saucer 10 is formed to have a rectangular cross section corresponding to the shape of the inner wall surface of the main body cylinder 1, and the protruding shafts 13 (on one side) that fit into the guide holes 5 of the main body cylinder 1 are provided on both opposing outer surfaces. (only shown) is provided.

A lid 14 that covers the upper end opening 2 of the main body cylinder 1 is attached to the top plate 1.
4a, and a pair of leg plates 15 that hang down along both outer wall surfaces of the main body cylinder 1, and the lower ends of both leg plates 15 are pivotally attached to the protrusion shafts 13, respectively, and the legs are vertically rotated around the protrusion shafts 13. It is configured to be rotatable. The means for pivotally attaching the leg plate 15 to the protrusion shaft 13 is as follows:
A small hole 13a is bored in the axial direction of the protruding shaft 13, and a shaft pin 15a that fits into the small hole 13a projects from the inner surface of the lower end of the leg plate 15. As shown in the figure, the leg plate 15 is formed in a front V-shape whose width gradually decreases toward the lower end, and on the other hand, the saucer 10 is provided on the outer wall surface of the main body cylinder 1 as shown in FIG. When sliding to the limit position, the lid 14 comes into sliding contact with the side edge 15b of the leg plate 15.
A step 16 is provided with a guide slope 16a for guiding the holder to its closed position. The thickness of this stepped portion 16 is set to be approximately equal to the plate thickness of the leg plate 15, and the guide slope 16a is also set in a V-shape corresponding to the front shape (V-shape) of the leg plate 15. 14 is in the closed state shown in FIG.
Care is taken so that the outer surface of the leg plate 15 and the outer surface of the stepped portion 16 are flush with each other, and the side edge portion 15b of the leg plate 15 and the guide slope 16a are also brought into close contact with each other to form a uniform continuous surface. . In the figure, the reference numeral 11a indicates a notch, and the reference numeral 17 indicates a bottom cover that closes the lower end opening of the operating barrel 6.

In the storage container having such a configuration, first, as shown in FIG. 2, when the operating tube 6 is rotated in the direction of dispensing the cosmetic A from the state where the lid 14 is in the closed position,
As the tray 10 rises, the lid 14 also rises as shown in FIG. At this time, since the lid 14 is pivotally attached to the saucer 10 via its leg plate 15,
Since the amount of rise is 0, that is, the same amount as the amount of dispensed cosmetic A, the so-called ceiling phenomenon in which the cosmetic A comes into contact with the ceiling surface of the lid 14 does not occur. When using the dispensed cosmetic A, the lid 14 may be rotated as shown in FIG. 4 by pressing lightly with the tip of a finger or the like. Note that if the pivoting of the lid 14 to the saucer 10 is set to be strong enough to allow the lid 14 to rotate under its own weight, the lid 14 can be moved to either the left or right side as shown in FIG. It rotates like a crab.

On the other hand, when the operation tube 6 is rotated in the cosmetic storing direction from the state shown in FIG. 4, the lid 14 also descends as the saucer 10 descends. As a result of the upper end of the guide slope 16a slidingly contacting the side edge 15b of the leg plate 15, the principle of a "lever" using the sliding contact point P as a fulcrum works, and the lid 14 gradually rotates in the direction of standing up and descends. do. In this way, the lid 14 is successively guided to its closed position by the guide slope 16a, and finally becomes automatically closed as shown in FIG.

5 to 8 show other embodiments of the present invention. In addition, in these figures, the same reference numerals are attached to the same components as those in the previous embodiment to simplify the explanation thereof.

In this embodiment as well, the lid 14 is set to close the upper end opening 2 of the main body cylinder 1 at the lowering limit position of the saucer 10, that is, at the closed position of the lid 14. This embodiment differs from the previous embodiment in that the saucer 10 is configured to be vertically rotatable around the protrusion shaft 13. That is, in this embodiment, the upper end opening edge 1a of the main body cylinder 1 is edged in an arc shape when viewed from the outer wall surface 1b side, and therefore the top plate 14a of the lid 14 that closes this part also follows the upper end opening edge. It is formed into a curved plate having an arcuate cross section approximately corresponding to the curvature of 1a. The curvature of the upper opening edge 1a and the top plate 14a is determined by considering the size and shape of the main body cylinder 1, the stroke of the saucer 10, etc., but in the embodiment, the curvature from the inner surface of the top plate 14a to the shaft pin 15a is determined. It is set to be approximately equal to the curvature of a circular arc whose radius is the straight line distance. Moreover, the center part of the upper end opening edge 1a of the main body cylinder 1,
That is, a hook 18 is provided at a position on the extension line of the guide hole 5, and a hook 19 is provided on the inner surface of the top plate 14a of the lid 14 to engage with the hook 18 and temporarily fix the lid 16 in its closed position. is provided. In the illustrated example, the hooks 19 are configured as a pair with the hook 18 sandwiched between them, and are designed to prevent the lid 16 from shifting from side to side.

Even in the case of such a configuration, the lid 14 is raised to the open state simply by rotating the operation barrel 6 in the cosmetic delivery direction, but in this embodiment, the lid 14 is opened in the closed state shown in FIG. It is convenient that it can be turned from the open state to the open state by rotating it to either the left or right as shown in FIG. 7, and that it can also be changed from the open state to the closed state.

In each of the above embodiments, for example, as shown in FIG.
4 may be provided with a convex portion 20 for rotation, and the lid 14 may be configured to automatically fall down at its raised position.

"Effects of the invention" As detailed above, according to the invention, an elongated hole extending vertically is formed in the circumferential wall of the fitting cylinder part provided in the lower half of the main cylinder, and the cosmetic material inside the main cylinder is formed. A sliding cylinder part that can freely slide inside the fitting cylinder part is provided at the lower part of the receiving tray, and a protrusion that fits into the spiral groove of the operating cylinder through the elongated hole is provided on the outer peripheral surface of the sliding cylinder part. Further, a guide hole extending in the vertical direction is formed in the outer wall surface of the main body cylinder, and a protruding shaft that fits into this guide hole is provided on the outer surface of the saucer, while a lid covering the upper end opening of the main body cylinder is provided.
The lid has a shape having a leg plate extending downward along the outer wall surface of the main body cylinder, and the lower end of the leg plate is pivotally connected to the protrusion shaft so as to be vertically rotatable about the protrusion axis, and the lid Since the top opening of the main body cylinder is closed at the lower limit position of the saucer, it is possible to perform the cosmetic dispensing operation and the lid opening operation at the same time by simply rotating the operating cylinder. If the lid has a sloped surface, the lid can be automatically closed in synchronization with the storage operation of the cosmetics, and these features provide extremely excellent operability. In addition, in this invention,
Since the leg plate provided on the lid is pivotally connected to the tray for holding cosmetics, the rotation radius of the lid itself is always constant regardless of the sliding position of the tray. No matter what sliding position the saucer is in, the lid itself will not come into contact with the cosmetic and damage it.
