Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a feeding container for storing a bar-shaped cosmetic material having a non-circular cross section.
[0002]
[Prior art]
In a bar-shaped cosmetic supply container for storing a bar-shaped cosmetic material having a non-circular cross-section, for example, an elliptical shape, an outer cylinder and a plate portion for raising and lowering the inside of the outer cylinder are formed in an elliptical cross-section like the bar-shaped cosmetic material. An operating member is pivotably attached to the lower inner side of the outer cylinder, and the operating member can be rotated from a window hole provided in the lower part of the outer cylinder. Some have a conversion mechanism for converting the rotational movement of the operation member into the linear movement of the plate. In this case, the cross-section of the cover cylinder that can be freely inserted into and removed from the outer cylinder is also elliptic.
[0003]
[Problems to be solved by the invention]
By the way, some stick-shaped cosmetics contain a volatile component, and an airtight mechanism is required in a feeding container for storing such stick-shaped cosmetics. However, in the case of a bar-shaped cosmetic material having a non-circular cross-section, as described above, the outer cylinder, the dish part, and the cover cylinder are all non-circular in cross-section, and the non-circular sliding portion is kept airtight. It was extremely difficult to do.
[0004]
On the other hand, another problem unrelated to the cross-sectional shape of the bar-shaped cosmetic material is that a cavity is formed in the bar-shaped cosmetic material when the bar-shaped cosmetic material is loaded. As a method of loading the bar-shaped cosmetic material into the bar-shaped cosmetic material feeding container, there is a method of filling the molten bar-shaped cosmetic material after assembling the feeding container. In this case, when the stick-shaped cosmetic material is filled, the heat of the space in the feeding container expands due to the heat, and the air invades into the dish part, thereby generating bubbles in the molten stick-shaped cosmetic material. there were. When the stick-shaped cosmetic material is solidified in the presence of the bubbles, there is a problem that cavities are formed in the stick-shaped cosmetic.
[0005]
The present invention has been made in view of the problems of the prior art as described above, and is a feeding container that accommodates a non-circular cross-section of a bar-shaped cosmetic, and has a simple structure and excellent airtightness. It aims at providing the stick-shaped cosmetics supply container which a cavity does not produce.
[0006]
[Means for Solving the Problems]
The present invention employs the following means in order to solve the above problems. The present invention provides a rod-shaped cosmetic material having a non-circular cross-section and a cross-sectional shape similar to that of the outer cylinder provided with a window hole in the base side peripheral wall surface, and a base portion of the bar-shaped cosmetic material is fitted inside the outer cylinder. It is arranged and can be moved in the axial direction with respect to the outer cylinder and mounted in a non-rotatable direction in the circumferential direction. An operating member that is mounted so as to be immovable in the axial direction, a conversion mechanism that is provided between the plate portion and the operating member and converts the rotational motion of the operating member into a linear motion of the plate portion, and the outer cylinder A stick-shaped cosmetic delivery container in which the stick-shaped cosmetic is filled with a molten stick-shaped cosmetic material from the upper opening of the outer cylinder and loaded . The outer cylinder includes a bottom wall portion that closes the base portion, a first annular wall portion that stands and extends from the bottom wall portion, and a moving area of the dish portion. A second annular wall portion provided on the base side and continuing to the inner peripheral surface of the outer cylinder, and the operating member is slidably pressed against the first annular wall portion and the second annular wall portion in a sealed state. A seal cylinder portion provided with a moving first seal ring portion and a second seal ring portion; the bottom wall portion of the outer tube and the seal tube portion of the operating member are arranged inside the seal tube portion and outside the outer tube; And a bottom wall portion is closed by a closing member, and the conversion mechanism is provided inside the first annular wall portion and the seal tube portion, and the lid A stick-shaped cosmetic material dispensing container is provided with a sealing member for sealing a space between the outer cylinder and the lid cylinder when the lid cylinder is fitted to the outer cylinder inside the top portion of the cylinder (Claim 1). Corresponding).
[0007]
In the bar-shaped cosmetic supply container of the present invention, when the operation member is rotated by operating the operation ring exposed from the window hole of the outer cylinder, the rotational movement of the operation member is converted into the linear movement of the dish by the conversion mechanism, The pan moves in the outer cylinder along the axial direction.
[0008]
The space between the outer cylinder and the operating member is sealed by the first annular wall portion and the first seal annular portion, and the second annular wall portion and the second seal annular portion, and the vent hole of the outer cylinder is closed by the closing member. Since the seal member seals between the outer cylinder and the lid cylinder when the lid cylinder is fitted, the bar-shaped cosmetic is stored in the sealed space surrounded by the outer cylinder, the operation member, and the lid cylinder when the lid is closed. Will be. Therefore, even if the stick-shaped cosmetic contains a volatile component, the volatilization of the volatile component can be prevented.
[0009]
Further, the sliding portion having a non-circular cross section does not need to be provided with a seal structure, and the structure is simplified.
[0010]
In the bar-shaped cosmetic material feeding container of the present invention, the vent hole in the bottom wall portion of the outer cylinder is opened when the molten bar-shaped cosmetic material is filled. Then, even if the air inside the container is heated and expanded when the bar-shaped cosmetic material is filled, the expanded air is exhausted out of the bar-shaped cosmetic supply container through the vent hole of the seal cylinder part and the vent hole of the outer cylinder. It is possible to prevent bubbles from forming in the bar-shaped cosmetic. If a sealing member is attached to the vent hole of the outer cylinder after filling the bar-shaped cosmetic and the vent is closed, the stick-shaped cosmetic feed container becomes a sealed container, and the volatile components of the bar-shaped cosmetic are volatilized and the outer cylinder passes. Outflow from the pores can be prevented.
[0011]
Considering such a functional aspect, it is preferable that the closing member can be mounted from the outside of the outer cylinder. The closing member may be a film adhered to the outer surface of the bottom wall portion, or a plug fitted into the vent hole.
[0012]
In the present invention, the non-circular cross section means a shape other than a perfect circle, for example, a rectangle such as a rectangle or a square, or an ellipse.
In the present invention, a screw mechanism can be exemplified as the conversion mechanism provided between the plate portion and the operation member.
[0013]
In this invention, the positional relationship between the first annular wall portion of the outer cylinder and the first seal annular portion of the operation member is such that the first annular wall portion is disposed either outside or inside the first seal annular portion. It doesn't matter. The same applies to the second annular wall portion of the outer cylinder and the second seal annular portion of the operation member, and the second annular wall portion may be disposed either outside or inside the second seal annular portion.
[0014]
The seal member only needs to be attached so as not to drop off from the lid cylinder, and the attachment structure is not particularly limited.
[0015]
In the stick-shaped cosmetic material supply container of the present invention, the shape of the sealing member is not particularly limited, but the sealing performance is very good and the condition is good as follows. That is, the seal member is provided with an annular projecting portion projecting inward in the middle of its inner peripheral surface and an annular seal projecting portion projecting outward on the lower edge of the outer peripheral surface. The cylinder is pressed against the outer peripheral surface and is elastically deformed outward so as to be pressed against the inner peripheral surface of the lid cylinder (corresponding to claim 2).
[0016]
In the stick-shaped cosmetic supply container according to the present invention, the seal member includes an elastic cylinder portion having a downwardly-divided shape that is spaced apart from the inner peripheral surface of the lid cylinder when not fitted, and more than the elastic cylinder section. An air vent hole is formed on the top side of the lid cylinder . (Corresponding to claim 1 ). If it does in this way, internal air can be discharged | emitted at the time of fitting of a cover cylinder, and a cover cylinder can be fitted reliably and smoothly.
[0017]
Although there is no limitation in material in each structure in the stick-shaped cosmetic material delivery container of this invention, it is also possible to form all that with a plastics.
[0018]

When the holder 30 is rotated, the holder 30 moves up and down in the small-diameter portion 13 so that the bar-shaped cosmetic can protrude from the outer cylinder 10. That is, in this embodiment, the conversion mechanism is constituted by the screw groove 35 of the holder 30 and the engagement protrusion 54 of the operation member 50.
[0032]
1 shows a state where the holder 30 is positioned at the lowest position, and a left half of FIG. 1 shows a state where the holder 30 is positioned at the highest position.
[0033]
The cover cylinder 70 is made of polypropylene and has a cross section formed in an elliptical shape similar to that of the outer cylinder 10. When fitted, the lower part is externally fitted to the middle diameter part 12 of the outer cylinder 10, and the lower edge is the large diameter part. 11 is hitting the upper edge. Further, in the lower part of the inner peripheral surface of the lid cylinder 70, a vertical groove 71 that engages with the engaging protrusion 16 of the outer cylinder 10 when fitted, and a horizontal groove that engages with the engaging protrusion 17 of the outer cylinder 10 when fitted. 72 is provided.
[0034]
A sealing member 80 is fitted and fixed inside the upper part of the lid cylinder 70. The seal member 80 is made of low-density polyethylene and has elasticity, has an elliptical cross section, and has a small diameter portion 81 at the top and a large diameter portion (elastic tube portion) 82 at the bottom. The upper part of the part 81 is fitted to the lid cylinder 70. An air vent hole 86 is provided below the small diameter portion 81.
[0035]
The large-diameter portion 82 has a downwardly widening shape, an annular projecting portion 83 projecting inward is provided in the middle of the inner peripheral surface, and an annular seal projecting outward at the lower edge of the outer peripheral surface. A protrusion 84 is provided.
[0036]
As shown by a two-dot chain line in FIG. 3, when the cover cylinder 70 is not fitted, the inner surface of the projecting portion 83 is formed slightly smaller than the outer peripheral surface of the tip portion of the small-diameter portion 13 of the outer cylinder 10. In addition, the outer peripheral surface of the seal projection 84 is formed slightly smaller than the inner peripheral surface of the peripheral wall portion of the lid cylinder 70 on the entire periphery.
[0037]
When the cover cylinder 70 is fitted to the outer cylinder 10, the small-diameter portion 13 of the outer cylinder 10 is fitted inside the protruding portion 83 while expanding the protruding portion 83 outward. As a result, the outer diameter portion 82 The tip part is also pushed outward, so that the entire circumference of the outer peripheral surface of the seal projection 84 is in pressure contact with the inner peripheral surface of the peripheral wall of the lid cylinder 70.
[0038]
That is, the large-diameter portion 82 of the sealing member 80 is sandwiched between the small-diameter portion 13 of the outer cylinder 10 and the peripheral wall portion of the lid cylinder 70 and is elastically deformed when the lid cylinder 70 is fitted. Due to the elastic restoring force, the protrusion 83 strongly presses the outer peripheral surface of the small-diameter portion 13 of the outer cylinder 10 around the entire circumference and seals between them, and the seal protrusion 84 extends around the inner circumference of the lid cylinder 70 around the entire circumference. The surface is tightly pressed to seal between them.
[0039]
The air vent hole 86 of the seal member 80 is for escaping the pressurized air confined in the seal member 80 during the fitting operation of the lid cylinder 70 to the outside.
That is, the inside of the seal member 80 communicates with the space 87 between the lid cylinder 70 and the seal member 80 through the air vent hole 86, and when the pressure in the space 87 rises, the pressure of the seal member 80 is increased by the pressure. The tip portion of the diameter portion 82 is elastically deformed inward to form a gap between the seal projection 84 and the inner peripheral surface of the peripheral wall portion of the lid cylinder 70, and air is released from this gap. When the air escapes and the pressure in the space 87 decreases, the tip of the large diameter portion 82 spreads again, and the seal projection 84 presses against the inner peripheral surface of the peripheral wall portion of the lid cylinder 70 and seals.
[0040]
[Operation during use]
In the stick-shaped cosmetic material supply container having the above-described configuration, the first annular wall portion 21 of the outer cylinder 10 and the first seal annular portion 58 of the operation member 50 slide in a sealed state, and the second annular wall portion 19 and The second seal ring portion 55 of the operation member 50 slides in a sealed state, the conversion mechanism is accommodated in the operation member 50 located on the inner side of these seal portions, and when the cover tube 70 is fitted, the outer tube 10 The space between the cover cylinder 70 is sealed by the large-diameter portion 82 of the seal member 80, and the vent hole 25 of the bottom cover 14 of the outer cylinder 10 is closed by the sealing sheet 26. The sheet 26, the operation member 50, the seal member 80, and the lid cylinder 70 are housed in a sealed space. Therefore, even if the stick-shaped cosmetic contains a volatile component, the volatilization of the volatile component can be prevented.
[0041]
Then, the seal in the sliding portion (that is, the sliding portion of the first annular wall portion 21 and the first seal ring portion 58 and the sliding portion of the second annular wall portion 19 and the second seal ring portion 55). Since the portion has an annular shape, the structure is simple, the moldability is good, and the sealability is good. Further, it is not necessary to provide a sealing structure for the elliptical sliding part (that is, between the dish part 31 and the small diameter part 13 of the outer cylinder 10), which is difficult to obtain a complete sealing structure.
[0042]
[Effect when stick cosmetic is loaded]
Further, when the stick-shaped cosmetic material is loaded in the stick-shaped cosmetic material feeding container, after assembling the outer cylinder 10, the holder 30, and the operation member 50, the sealing sheet 26 is not adhered to the bottom cover 14. As shown in the right half in FIG. 1, the holder 10 is positioned at the lowest position, and the molten bar-shaped cosmetic material can be filled from the upper opening of the outer cylinder 10.
[0043]
Even when the air in the space formed between the outer cylinder 10, the holder 30, and the operation member 50 is expanded by the heat of the molten stick-shaped cosmetic material during the filling, the expanded air passes through the operation member 50. The air is exhausted to the outside through the air holes 59 and further through the air holes 25 of the bottom lid 14. Therefore, the expanded air does not escape above the dish part 31 and does not cause bubbles in the stick-shaped cosmetic material. As a result, no void is generated in the stick-shaped cosmetic material after filling and solidification.
[0044]
In addition, after solidifying the stick-shaped cosmetic, the stick-shaped cosmetic can be accommodated in the sealed space as described above by sticking the sealing sheet 26 to the bottom lid 14 and closing the vent hole 25.
[0045]
【The invention's effect】
As described above, according to the present invention, when the cover cylinder is fitted to the outer cylinder, the bar-shaped cosmetic material having a non-circular cross section is stored in a sealed space surrounded by the outer cylinder, the operation member, and the cover cylinder. And an excellent effect that the volatile component can be surely prevented from volatilizing from the stick-shaped cosmetic is produced. In addition, since the non-circular sliding portion does not need to be provided with a seal structure, the structure is simple.
[0046]
When the elastic member is provided on the sealing member, the sealing performance is very good.
When the air vent hole is provided in the seal member, the cover tube can be securely and smoothly fitted.
[0047]
Furthermore, vent holes are provided in the seal cylinder part of the operating member and the bottom wall part of the outer cylinder, respectively, so that the inside of the seal cylinder part and the outside of the outer cylinder can be communicated with each other. If the molten stick-shaped cosmetic material is filled, the expanded air can be exhausted to the outside even if the air in the seal cylinder is heated and expanded by the heat at the time of filling. There is no cavity in the material. If the air hole of the bottom lid is closed with the closing member after solidifying the bar-shaped cosmetic, the bar-shaped cosmetic can be stored in the sealed space as described above.
