Description

[Detailed Description of the Invention] The present invention relates to a lipstick container for storing bar-shaped products such as lipstick, lip balm, stick eyeshadow, and stick foundation.

Conventionally, a container for storing lipstick consists of a container body 1 and a cap 2 fitted into the container body 1, as shown in FIG. A cap stopper member 6 having a plurality of protrusions 5 fixed to the opening 4
an inner cylindrical member 8 having a notch 7 formed in the vertical direction and fixed in the cylindrical member 3 so as to protrude from the opening 4 of the cylindrical member 3; A slideable lipstick supporting dish member 10 having a guide pin 9 that engages with a notch 7 of 8.
and an elastic guide member 12 which is interposed between the hook member 3 and the inner cylinder member 8 and has a spiral guide groove 11 for guiding the guide pin 9, and this guide member 12 is fitted inside. , and an outer cylinder member 13 that covers the guide member 12 and the like located between the cap stopper member 6 and the like.

However, the conventional lipstick container constructed in this way has the following drawbacks.

(1) It has a large number of parts, takes time to assemble, and is expensive.

(2) Since the elastic guide member having a spiral guide groove and the inner cylinder member having a vertical notch are made of metal, machining is difficult and expensive.

(3) An inner cylindrical member, a guide member, and an outer cylindrical member are required on the outer periphery of the dish member that supports the lipstick, and since these parts are processed from metal materials, processing is difficult and costs are high.

(4) Since the inner cylindrical member is simply inserted into the outer cylindrical member, it either comes off easily, or the fit is too tight, making it impossible to rotate the member smoothly.

In view of the above-mentioned conventional drawbacks, the present invention has a small number of parts, is easy to assemble, and
It is an object of the present invention to obtain a container for lipstick, etc., in which an inner cylindrical member and an outer cylindrical member can be fitted in an optimal state, and which is easy to manufacture and can reduce costs.

The present invention will be explained in detail below with reference to embodiments shown in FIGS. 2 to 9.

In the embodiment shown in FIGS. 2 to 6, reference numeral 21 denotes an inner cylinder member molded from a synthetic resin material, and as shown in FIG.
2, guide grooves 23, 23 formed in the axial direction of the inner cylindrical member main body 22, which are also open at the upper end, and lateral grooves 2 formed at the upper and lower parts of the guide grooves 23, 23.
4, 24, 25, 25 and this upper horizontal groove 24, 2
a protrusion 26 for preventing slippage, which is formed to protrude into the guide grooves 23, 23 at a position corresponding to 4;
26, and a fitting portion 27 having an elliptical cross section formed at the lower part of the inner cylinder member main body 22 as shown in FIG.
, a projection 28 formed on the fitting portion 27 to prevent slipping off, and a hook member 29 integrally formed at the lower part of the inner cylinder member main body 22 .
Reference numeral 30 denotes an outer cylinder member molded from a synthetic resin material that covers the outer periphery of the inner cylinder member main body 22;
As shown in FIG. 5, a cylindrical outer cylinder member main body 31
and a perfect circular shape that fits into the spiral grooves 32, 32 formed on the inner wall of the outer cylinder member main body 31 and the fitting portion 27 formed at the lower part of the outer cylinder member main body 31 as shown in FIG. and an engaging protrusion 34 that engages with the protrusion 28 formed on the fitting part 33 to prevent it from coming off. Reference numeral 35 denotes a tray member that supports a lipstick 36 etc. molded from a synthetic resin material that moves up and down inside the inner cylinder member 21, and the guide groove 2 of the inner cylinder member 21 is attached to this tray member 35.
3 and 23 and the spiral groove 3 of the outer cylinder member 30
Engagement pins 37, 37 that engage with 2, 32 are integrally molded.

In the above structure, the inner cylinder member 21 is inserted into the outer cylinder member 30, and the fitting part 33 of the outer cylinder member 30 is fitted into the fitting part 27 of the inner cylinder member 21. Due to this fitting, a force is applied to the fitting portion 27 of the inner cylinder member 21 to form a perfect circle, so that the fitting portion 27 of the inner cylinder member 21 is elastically fitted. Further, since the protrusion 28 and the engagement protrusion 34 engage with each other, it is possible to prevent the protrusion from coming off. After the inner cylindrical member 21 and the outer cylindrical member 30 are assembled in this way, the dish member 3 on which the lipstick 36 and the like are supported
5 into the inner cylinder member 21 from the upper part of the inner cylinder member 21. At this time, the engagement pins 37, 3 of the dish member 35
7 is inside the guide grooves 23, 23 and the spiral grooves 32, 3.
However, if the engaging pins 37, 37 are inserted inside (lower) than the retaining protrusions 26, 26, the plate member 35 will not come out due to vibrations during carrying or transportation. It can be prevented from coming off by the projections 26, 26. Note that the outer cylinder member 30
When the plate member 35 is rotated by holding and rotating the hook member 29, the dish member 35 moves up and down by the spiral grooves 32, 32 of the outer cylinder member 30.

Next, different embodiments of the present invention shown in FIGS. 7 to 9 will be explained. In the description of these embodiments, the same parts as those of the embodiments of the present invention are designated by the same reference numerals and redundant explanations will be omitted.

The embodiment shown in FIG. 7 is mainly different from the embodiment of the present invention in that a cap fitting part 40 is formed on the upper outer periphery of the hook member 29A to fit into the fitting part 39 of the cap 38. With this configuration, the outer periphery of the outer cylinder member 30 can be covered with the cap 38.

In the embodiment of Figure 8, the main difference from the above-mentioned embodiment of the present invention is that an engaging protrusion 41 is formed on the upper outer periphery of the inner tube member 21 to prevent the outer tube member 30 from slipping off.By configuring in this manner, it is not necessary to form the protrusion 28 and the engaging protrusion 34 on the fitting portion 27 of the inner tube member 21 and the fitting portion 33 of the outer tube member 30.

The embodiment shown in FIG. 9 is mainly different from the embodiment of the present invention in that a flange portion 42 is formed on the upper surface of the outer cylinder member 30, and the upper wall 21a of the inner cylinder member 21 is formed by this flange portion 42. With this configuration, there is no need to form a protrusion to prevent the device from coming off.

As is clear from the above description, the present invention has the following effects.

(1) A fitting part with an elliptical cross-sectional shape of the inner cylinder member is formed at a position near the bottom of the inner cylinder member, and a perfectly circular fitting part is formed on the outer cylinder member to fit with the fitting part. Since a portion is formed, the contact area of the fitting portion is small, and the inner cylinder member and the outer cylinder member can be fitted in an optimal state where the rotation operation is performed smoothly.

(2) Due to (1) above, even if there is a dimensional error in the fitting part of the inner cylinder member or the fitting part of the outer cylinder member, they will be fitted in an elastic state, so they will fit in the optimal state and will not be It is not necessary to increase the dimensional accuracy.

(3) If a protrusion is formed on the fitting part of the inner cylinder member and an engagement protrusion is formed on the fitting part of the outer cylinder member, the protrusion can be removed by fitting the inner cylinder member and the outer cylinder member. The engagement between the part and the engagement protrusion can reliably prevent slippage.

(4) The number of parts is small because the inner cylinder member, outer cylinder member, and plate member are all needed, and assembly is easy.
Cost reduction can be achieved.

(5) The inner cylindrical member, outer cylindrical member, and plate member can be molded from synthetic resin material, so they are easy to process.
