Abstract

PROBLEM TO BE SOLVED: To provide a container in which contents can be efficiently stirred.SOLUTION: When a user shakes the container 100, a stirring chip 20 is made movable in the axial direction inside a large-diameter spring 21b that composes a spring 21 and, as a result, the stirring chip 20 moves in the axial direction, with contents L stirred by the movement of this stirring chip 20. In addition, with the stirring chip 20 colliding with a small-diameter spring 21a that composes the spring 21, that is situated adjacently in the axial direction to the large-diameter spring 21b, and that has a smaller diameter than the stirring chip 20, the small-diameter spring 21a thereby contracts/extends in the axial direction, further stirring the contents L by the contraction/extension of this small-diameter spring 21a. Furthermore, the large-diameter spring 21b contracts/extends in the axial direction by receiving an elastic force by the contraction/extension of the small-diameter spring 21a, further stirring the contents L by the contraction/extension of this large-diameter spring 21b. Thus, by adding the contraction/extension of the large-diameter spring 21b, in addition to the movement of the stirring chip 20 and the contraction/extension of the small-diameter spring 21a, the contents L are efficiently stirred.SELECTED DRAWING: Figure 1

  Here, in the liquid cosmetic container 100 of the present embodiment, the container 2 and the liquid cosmetic L are accommodated together with the stirring bar 20 that can move in the axial direction and the coil spring 21 that can expand and contract in the axial direction. ing. Here, the stirrer 20 is particularly preferably a sphere, but may be a polyhedron or a cone.

  As shown in FIG. 3, the coil spring 21 is an integrally formed spring in which a plurality of spring portions 21a and 21b having different diameters (here, two spring portions having different diameters) are integrally connected in the axial direction. Then, it is molded from, for example, SUS. The coil spring 21 includes a small-diameter spring portion 21a having a smaller diameter than the diameter of the stirrer 20 in the rear half, and a large-diameter spring portion having a diameter larger than the diameter of the stirrer 20 adjacent to the front of the small-diameter spring portion 21a in the axial direction. 21b is provided in series.

  As shown in FIGS. 1 and 2, the coil spring 21 has an axial length that is approximately half of the total axial length in the housing portion 2, and is movable in the axial direction. The coil spring 21 has a small-diameter spring portion 21 a that can enter the cylindrical hole of the bottomed cylindrical tail plug 7, and the large-diameter spring portion 21 b approaches the inner peripheral surface of the housing portion 2 of the container body 1. It is configured to the diameter to be.

  In the liquid cosmetic container 100 configured as described above, the liquid cosmetic L in the housing portion 2 flows out toward the tip brush 3 via the relay core 4 and is applied by the user to the brush 3. Used for application.

  Here, when the user shakes the container 100, the stirring bar 20 is movable in the axial direction within the large-diameter spring portion 21b constituting the coil spring 21, so that the stirring bar 20 moves in the axial direction. The liquid cosmetic L is stirred by the movement of the stirring bar 20. Further, when the stirrer 20 constitutes the coil spring 21 and is positioned next to the large diameter spring part 21b in the axial direction and collides with the small diameter spring part 21a having a smaller diameter than the stirrer 20, the small diameter spring part 21a expands and contracts in the axial direction. The liquid cosmetic L is further stirred by the expansion and contraction of the small diameter spring portion 21a. Further, the large-diameter spring portion 21b expands and contracts in the axial direction by receiving the elastic force due to expansion and contraction of the small-diameter spring portion 21a, and the liquid cosmetic L is further stirred by the expansion and contraction of the large-diameter spring portion 21b.

  Thus, in this embodiment, in addition to the movement of the stirrer 20 and the expansion / contraction of the small-diameter spring part 21a, the expansion / contraction of the large-diameter spring part 21b is added, so that the liquid cosmetic L can be efficiently stirred.

  Further, since the coil spring 21 is movable in the axial direction in the accommodating portion 2, when the user shakes the container 100, the coil spring 21 moves (reciprocates) in the axial direction. In addition to the movement of and the expansion and contraction of the small diameter spring portion 21a and the large diameter spring portion 21b, the liquid cosmetic L can be stirred more efficiently by the coil spring 21 that moves in the axial direction.

  Further, since the coil spring 21 has a large-diameter spring portion (maximum diameter spring portion) 21b positioned at the tip portion, the large-diameter spring portion 21b causes the peripheral edge of the tip portion of the housing portion 2 that cannot be reached by the stirrer 20 to the coil spring 21. The dead space can be stirred by the movement and / or the expansion and contraction thereof, and the liquid cosmetic L can be stirred more efficiently.

  In the coil spring 21, the spring constant, the winding diameter, the winding pitch, and the density of the winding can be selected as appropriate so that the above-described effects can be suitably achieved.

  Incidentally, in 1st Embodiment, the opening of the rear end of the container main body 1 is closed by the bottomed cylindrical tail plug 7, and the inner peripheral surface of the accommodating part 2 of the container main body 1 is not a uniform diameter on the front side and the rear side. In this case, an optimal coil spring 21 (a coil spring 21 in which the front large-diameter spring portion 21b approaches the inner peripheral surface of the housing portion 2 and the rear small-diameter spring portion 21a can enter the cylindrical hole of the tail plug 7) was used. Although an example is shown, in the liquid cosmetic containers 200 and 300 of the following second and third embodiments, the container body 1 is configured such that the front container body 1x and the rear container body 1y cannot move in the axial direction and are circumferential. It is made into the bottomed cylindrical shape united so that it cannot rotate, and there is no tail plug 7. In the liquid cosmetic containers 200 and 300 of the second and third embodiments, the gripping cylinder 6 is omitted and not drawn.

  4 is a cross-sectional view showing a container according to a second embodiment of the present invention, in which the coil spring is not cut, FIG. 5 is a full cross-sectional view of the container, and FIG. 6 is a perspective view of the coil spring in FIGS. FIG.

  As shown in FIGS. 4 and 5, the liquid cosmetic container 200 of the second embodiment is different from the liquid cosmetic container 100 of the first embodiment in that it is replaced with a coil spring 21 in which two spring portions are connected. This is a point using a coil spring 22 in which three spring portions are connected.

  As shown in FIG. 6, the coil spring 22 includes a small-diameter spring portion 22 a having a smaller diameter than the diameter of the stirrer 20 in the middle in the axial direction, and adjacent to the front and rear of the small-diameter spring portion 22 a in the axial direction. Large diameter spring portions 22b and 22c having a diameter larger than the diameter are provided in series.

  As shown in FIGS. 4 and 5, the coil spring 22 is configured such that the large-diameter spring portions 22 b and 22 c approach the inner peripheral surface of the housing portion 2 of the container body 1. Further, the coil spring 22 has a length in the axial direction that is slightly longer than about half of the total length in the axial direction in the housing portion 2, and is movable in the axial direction as in the first embodiment.

  In the liquid cosmetic container 200 configured as described above, when the user shakes the container 200, the stirrer 20 is movable in the axial direction within the large-diameter spring portion 22 b constituting the coil spring 22. Therefore, the stirrer 20 moves in the axial direction, and the liquid cosmetic L is stirred by the movement of the stirrer 20, and the stirrer 20 constitutes the coil spring 22 and is positioned next to the large-diameter spring portion 22b in the axial direction. When the stirrer 20 collides with the small diameter spring portion 22a, the small diameter spring portion 22a and the rear large diameter spring portion 22c expand and contract in the axial direction, and the small diameter spring portion 22a and the rear large diameter spring portion 22c. The liquid cosmetic L is further agitated by the expansion and contraction, and the front large-diameter spring portion 22b expands and contracts in the axial direction under the elastic force of the small-diameter spring portion 22a and the rear large-diameter spring portion 22c. ,before this Liquid cosmetic L is further agitated by the expansion and contraction of the large diameter spring portion 22b of.

  Thus, in the second embodiment, in addition to the movement of the stirring bar 20 and the expansion / contraction of the small-diameter spring portion 22a and the large-diameter spring portion 22c on the rear side, the expansion / contraction of the large-diameter spring portion 22b on the front side is added. The material L can be efficiently stirred.

  Also in the second embodiment, the coil spring 22 is movable in the axial direction in the housing portion 2, so that when the user shakes the container 100, the coil spring 22 moves in the axial direction (reciprocating movement). In addition to the movement of the stirrer 20 and the expansion and contraction of the small-diameter spring portion 22a and the large-diameter spring portions 22b and 22c, the liquid cosmetic L can be more efficiently stirred by the coil spring 22 that moves in the axial direction. .

  Further, since the coil spring 22 has large diameter spring portions (maximum diameter spring portions) 22b and 22c at the front end portion and the rear end portion, respectively, the large diameter spring portions 22b and 22c reach the stirrer 20. The dead space at the periphery of the end portion of the non-accommodating portion 2 can be stirred by the movement and / or expansion and contraction thereof, and the liquid cosmetic L can be stirred more efficiently.

  The large-diameter spring portions 22b and 22c do not have to have the same diameter, for example. In short, the coil spring includes a small-diameter spring portion having a smaller diameter than the diameter of the stirrer 20, and is adjacent to the small-diameter spring portion in the axial direction. The large diameter spring part larger than the diameter of the stirrer 20 is connected, and the stirrer 20 may be moved in the axial direction in the large diameter spring part. Therefore, the stirrer 20 may be disposed so as to be movable in the axial direction in the rear-side large-diameter spring portion 22c.

  FIG. 7 is a cross-sectional view showing a container according to the third embodiment of the present invention, and is a view in which the coil spring is not cut, and FIG. 8 is a full cross-sectional view showing the container according to the third embodiment of the present invention.

  The liquid cosmetic container 300 of the third embodiment is different from the liquid cosmetic container 200 of the second embodiment in that the axial length of the cosmetic container 300 is not the coil spring 22 that does not reach the entire axial length in the housing portion 2. The length in the axial direction is that the coil spring 23 is used over the entire length in the axial direction in the accommodating portion 2.

  Even in the liquid cosmetic container 300 configured in this manner, the movement of the stirring bar 20 and the small-diameter spring portion 23a and the rear-side large-diameter spring portion 23c are similar to the liquid cosmetic container 200 of the second embodiment. In addition to expansion and contraction, expansion and contraction of the large-diameter spring portion 23b on the front side is added, so that an effect of efficiently stirring the liquid cosmetic L can be obtained, and the coil spring 23 has a large-diameter spring portion (maximum Since the large diameter spring portions 23b and 23c are positioned, the dead space at the periphery of the end portion of the housing portion 2 that cannot be reached by the stirrer 20 can be stirred by expansion and contraction. In addition to the effect that the liquid cosmetic L can be stirred more efficiently, the coil spring 23 extends over the entire length in the housing portion 2, so that the coil spring extends over the entire length in the housing portion 2. 23 expands and contracts The expansion and contraction of the coil spring 23 over the entire length, a liquid cosmetic L can be more efficiently stirred.

  As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above embodiment. For example, in the above embodiment, two or more spring portions having different diameters are used. Although three spring portions are connected, four or more spring portions may be connected. In short, the coil spring includes a small diameter spring portion smaller in diameter than the diameter of the stirrer 20, and The large diameter spring part larger than the diameter of the stirrer 20 is connected next to the axial direction, and the stirrer 20 only needs to be movable in the axial direction within the large diameter spring part.

  In the above embodiment, the coil springs 21 to 23 are particularly preferably used, but it is also possible to use a so-called resin spring having a substantially spiral slit on the peripheral surface and capable of expanding and contracting in the axial direction. Also in this case, a plurality of spring portions having different diameters are integrally connected in the axial direction, and provided with a small-diameter spring portion having a smaller diameter than the diameter of the stirrer 20, What is necessary is just to provide the large-diameter spring part larger than a diameter in a row.

  Moreover, in the said embodiment, although the content L is made into liquid cosmetics, and the application body 3 is made into a brush, it is not limited to these, For example, ink, such as a writing instrument, liquid is not limited to these. The application body 3 may be a foam such as a sponge, a projection group having a brush function, or the like.
