Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lipstick container in which a lipstick is moved to an extruded position when used, and is retracted and kept closed when not in use.

[0002]

[Prior art]

 A lipstick or other stick-shaped cosmetic container begins with removing the cover in use, and then rotates the base clockwise or counterclockwise while holding the sleeve, whereby the lipstick or other The cup filled with the stick cosmetic is moved up or down as the base rotates. This is the configuration of a typical lipstick container.

[0003] In general, a lipstick container is composed of six members including a cup, a cup mover, a sleeve, a ring, a base, and a cover. The user first removes the cover, then moves the cup up and down by holding the sleeve immobile and simultaneously rotating the base. Since the cup mover is fitted to the base, it can be moved with the rotation of the base. If the base is rotated clockwise, the cup is moved down. If the base is rotated counterclockwise, the cup will be moved upwards.

[0004]

[Problems to be solved by the invention]

 Generally, lipstick or stick cosmetics are filled into the container portion of the cup from the top opening of the cup, so that air or other contaminants from the outside can enter the lipstick container. In use, once the lipstick is moved upwards toward the top and then downwards, sometimes the lipstick filled in the cup does not move downwards. Exposure to the outside air may impair or degrade its quality.

[0005] Further, the conventional lipstick container employs a mechanism composed of at least six members, so that manufacturing and assembling are troublesome, and the manufacturing cost is further increased.

[0006] An object of the present invention is to avoid the above-mentioned quality control problems that occur at the time of filling, to allow filling in an airtight state, and to provide a simple method comprising only four members instead of six members. It is an object of the present invention to provide a lipstick container which can maintain quality for a long period of time and is economically advantageous.

[0007]

[0009]

[Embodiment of the invention]

 1 to 17, the lipstick container according to the present invention comprises a cup 2, a sleeve 13, a ring 21, an outer shell 36, an airtight cap 37, and an airtight base plug 34 or 32. It should be noted that “lipstick” or “lipstick material” in the present invention should be interpreted as a general solidified stick-shaped kneaded article.

As shown in FIG. 6, the cup 2 has an elongated cylindrical outer shape composed of an upper part 3 and a lower part 7. A hole 5 through which the viscous material of the lipstick 1 can be filled penetrates the cup 2 from the lower end, that is, the bottom. As shown in FIGS. 3 and 17, the cup 2 can close the bottom of the hole 5 by the bottom plug 33 of the hermetic base plug 32. Two opposing stoppers 8 are provided on the outer peripheral surface of the bottom, which is the lower end of the cup 2, so as to protrude in the diameter direction so as to restrict the rotation of the cup 2. Two opposing spiral ridges 4 are formed above the stopper 8 along the lower part 7 and fit into the spiral grooves 23 of the ring 21 shown in an enlarged manner in FIG.

As shown in FIG. 5, two opposing smooth surfaces 34 are formed on the outer peripheral surface of the lower portion 7 of the cup 2. Further, as shown in FIG. 10, the smooth opposing surfaces 34 are housed together with the spiral ridges 4 in the housing 18 of the sleeve 13. As shown in FIG. 5, at the upper end of the smooth surface 34 there are two protrusions 10 which lock the cup 2 when the cup 2 is moved down towards the bottom end. In order to achieve this, they are provided diametrically opposed.

In the upper part 3, the outer diameter of the bottom part 11 is larger than the inner diameter of the upper step part 38 formed on the inner surface of the lower end of the sleeve 13, and can be abutted thereon. In addition, a mounting ring 9, which is an annular groove that fits the diameter of the mounting ring 16, which is a rib whose diameter protrudes from the inner peripheral surface of the sleeve 13, is formed on the outer peripheral surface.

The top 6 of the cup 2 has an enlarged diameter that fits the inside diameter of the tubular sleeve 13. As can be seen in FIGS. 1, 2 and 3, the sleeve 13 has a cylindrical shape with an internal through-hole for accommodating the cup 2 movably in the axial direction. If the cup 2 is moved continuously downwards, the mounting ring 9 snaps onto the mounting ring 16 (FIG. 10) so that the user can recognize that the cup 2 has reached the lower limit position. Are combined. At the same time, the bottom portion 11 of the upper portion 3 of the cup 2 abuts against the upper step portion 38 of the sleeve 13 so as to prevent further movement downward.

The inner diameter of the sleeve 13 accommodates the spiral ridge 4 of the cup 2, so that the housing 18 has an inner diameter adapted to the outer diameter of the spiral ridge 4, as shown in FIG. In the circumferential portion 19, in order to guide the axial movement of the cup 2, corresponding to the smooth surface 34 formed on the lower portion 7 of the cup 2, it is opposed to the housing 18 at a separation distance shorter than the inner diameter of the housing 18. A flat surface is formed. As can be seen mainly in FIGS. 2 and 3, the reduced diameter portion 12 of the sleeve 13 is recessed on the outer peripheral surface corresponding to the circumferential portion 19 which is arranged opposite to the sleeve 13, and the sleeve 13 comes off the predetermined position. In order to prevent this, a lock portion 22 is provided which protrudes inward from the inner peripheral surface of the ring 21. A lower step 20 formed below the circumferential portion 19 of the sleeve 13 is in contact with the inner top stopper 27 of the ring 21 (see FIG. 13). The top of the sleeve 13 is covered with an airtight cap 35 so that the tip of the lipstick can be sealed in the sleeve.

The above-described ring 21 has a cylindrical shape as shown in FIGS. The inner wall of the ring is in circumferential contact with the outer wall of the sleeve. The ring 21 has a locking portion 22 which engages the reduced diameter portion 12 of the sleeve 13. An inner top portion 27 is provided for axially supporting the lower step portion 20 of the sleeve 13 so that the sleeve 13 does not slide further downward. An annular groove 28 (FIG. 13) for entering the base portion 15 which forms the lower end of the sleeve 13 has a spiral groove 23 for engaging with the spiral ridge 4 of the cup 2 on the inner peripheral surface. It is defined between the lower end and the inner cylinder turned back.

Outside the ring 21, two axially-spaced fitting portions projecting from the outer shell 36 formed by the hermetic cover plug 37 and the hermetic base plugs 34 and 32 are provided. . The upper fitting part 25 fits into the airtight cover plug 37 and the lower fitting part 24 fits into the airtight base plug 34 or 32. The diameter of the lower fitting portion 24 is slightly larger than that of the upper fitting portion 25 because the force for extracting the lower fitting portion 24 is different. The user can extract only the airtight cover plug 37 while the airtight base plug 34 or 32 is still fitted in the ring 21. Therefore, the user cannot remove the hermetic base plug 34 or 32 without first removing the hermetic cover plug 37. Referring to FIG. 17, the lower fitting portion 24 can be fitted with the cut 39 of the hermetic base plug 32, so that higher hermeticity of the hermetic base plug 32 is ensured.

The hermetic base plug 34 has a notch 37 (FIG. 15) therein for fitting with the lower fitting portion 24 of the ring 21, and the higher hermeticity of the hermetic base plug 34 is improved. Is secured. The base and cover 36 are the same member and are removable with different forces. Of course, the diameter of the lower fitting portion 24 is set slightly larger than that of the upper fitting portion 25 because the force for extracting the lower fitting portion 24 is different, so that the airtight cover plug 37 is larger than the airtight base plug 34. , Can be removed with a small pulling force.

In FIG. 16, the inner diameter of the airtight cap 35 is the same as the outer diameter of the upper end of the sleeve 13. Although it is possible to engage the airtight cover plug 37 with the ring 21 with the cap 35 attached to the sleeve 13, use of the airtight cap 35 alone will reduce the original function of the lipstick container. In addition, it is preferable because it does not impair the effects.

In FIG. 17, the airtight base plug 32 has exactly the same appearance as the other plugs, but the bottom plug 33 closes the hole 5 to make the inside of the lower portion 7 of the cup 2 airtight. I have. The cut 39 formed in the inner peripheral surface of the upper portion is fitted into the lower fitting portion 24 of the ring 21.

As is evident from the arrangement described above, the lipstick 1 is housed in a cup 2, which is incorporated in a sleeve 13 which is incorporated in a ring 21. The ring 21 is covered at the bottom by an airtight base plug 34 or 32 and at the top by an airtight cover plug 37. As described above, the outer shell 36 composed of two identical parts is connected to the airtight base plug 32 and the airtight cap 35 for the purpose of good airtightness, cost reduction, and good quality maintenance. By replacing the combination, only one outer shell 36 can be provided.

The assembly and operation of this container will be described. First, the cup 2, the sleeve 13, and the ring 21 are assembled together. The lipstick 1 is filled by the filling machine through a hole 5 penetrating from the bottom of the cup 2 to the inside. When filling is complete, the bottom of the cup 2 is covered by a hermetic base plug 34 or 32 that fits into the ring 21. The cup 2 is moved up or down by rotating the airtight base plug 34 or 32 and simultaneously holding the sleeve 13 by hand by the user. The upper part 3 of the cup 2 has an enlarged diameter whose outer diameter fits the inner diameter of the sleeve 13, while the lower end of the lower part 7 of the cup 2 is fed out at its upper limit position. In order to stop the stop, a stopper 8 that can abut on the bottom end 26 of the ring 21 is protrudingly provided.

As the cup 2 moves upward, its spiral ridge 4 is driven in alignment with the spiral groove 23 of the rotating ring 21 and raises the cup 2 vertically with the lipstick 1 inside the sleeve 13. The smooth portion 34 is in contact with a circumferential portion 19 formed by opposed flat surfaces provided on the housing 18, and guides the vertical movement while preventing the rotation of the cup 2.

When the cup 2 is moved downward, the mounting ring 9 engages with the mounting ring 16 of the sleeve 13. There are two protrusions 10 that match the reduced diameter portion 17 of the sleeve 13 to feel locked and the upper portion bottom 11 contacts the upper step 38 of the sleeve 13 to stop moving. Inside the sleeve 13, the lower step 20 abuts the inner top stopper 27 of the ring 21, and the base portion 15, which constitutes the lower end of the cylinder below, is formed by the groove 28 of the ring 21. It is inserted inside. Outside the sleeve 13 there is a reduced diameter portion 12 recessed in the outer peripheral surface of the ring 21 corresponding to the circumferential portion 19, which is locked by a locking portion 22 to tighten the sleeve 13.

The ring 21 has an upper fitting formed by a radially outwardly extending projection provided in the axial direction so as to be fitted to the airtight cover plug 37 and the airtight base plug 34 or 32. A mating portion 25 and a lower fitting portion 24 are formed. The airtight cover plug 37 and the airtight base plug 34 or 32 are each detachable from the ring 21, and are fitted to the lower fitting portion 24 of the ring 21 and the end opening of the hole 5 of the cup 2. It can be replaced by a hermetic base plug 32 with a plug 33 and a hermetic cap 35 fitted to the sleeve 13.

In this case, the lipstick container can be filled with the lipstick directly from the bottom of the hole of the cup by a filling machine by a method called “direct filling”, and the lipstick can be airtight after filling. The plug is fitted and sealed, while other directly filled lipstick containers hold the lipstick on the base, and after filling, the hole in the cup is closed by a non-hermetic sticker.

Also, the invention is economical to use the same mold because the hermetic base plug and hermetic cover plug are of the same shape, and the ring is such that the base fits and the cup moves. It has a number of functions. Although these base plugs and cover plugs are the same member, they can be removed with different forces (normal force on the cover, more force on the base), which makes it very difficult to change the outer design. It is convenient. In addition, it can be replaced by an airtight base plug with a bottom cap 33 and a simple structure airtight cap, which keeps the manufacturing costs low and allows refilling of the lipstick.
