Description

  The present invention relates to a coating container containing liquid cosmetics such as mascara, hair dyes, and the like. More specifically, a stable coating is applied to eyelashes, hair, and the like by attaching an appropriate amount of coating solution to a coating part made of a spring member. It is related with the application | coating container which can perform.

  Conventionally, many application containers such as mascara have been known. This mascara container contains mascara liquid in the container body, impregnating the mascara liquid with an application part such as a brush member provided in the cap, and squeezing the mascara liquid adhering to the application part when using it to an appropriate amount. It is something to apply.

  In this mascara application container, it is already known that a metal wire is formed in a spring shape and used as a mascara application part in addition to a brush member as a mascara application part in order to exhibit stable application. For example, as shown in FIG. 7, one end of a wire rod made of a corrosion-resistant material such as stainless steel is fastened to the tip of an application rod 1b fixed to a cap (handle) 1a, and a spring-like application portion 1c is screwed. A mascara applicator 1 (see, for example, Patent Documents 1 and 2) characterized in that the end is fastened, or an applicator bar 2b implanted in a cap 2a as shown in FIGS. 8 (a) and 8 (b). A mascara applicator 2 in which a spiral groove 2c shallower than the radius of the thin wire is formed around the tip of the wire, and a thin metal wire 2d is wound around the spiral groove 2c to form the application portion 2e (for example, Patent Documents) 3) is known.

Further, as shown in FIGS. 9A and 9B, a mascara applicator 3 provided with an applicator portion 3c formed by winding a spring around the end of the shaft member 3b of the cap 3a and a spring stopper 3d, When the mascara applicator 3 is used, it is inserted into the mascara storage container 4 with the wiping member 4a to attach the mascara to the application part 3c, and then when the shaft member 3b is pulled out from the container 4, the wiping member 4a A mascara application container (see, for example, Patent Document 4) in which an appropriate amount of mascara can be adhered to the application part 3c by squeezing off an excessive amount of mascara adhering to the application part 3c after the spring is compressed, and eyelashes to the application destination The application state for the mascara can be changed in two stages by double coil springs inside and outside, and the application amount can be changed in two ways, as well as the extra masker attached to this application bar The coating container can be scraped off by the skirt of the coating solution limits cylinder attached to the container opening (e.g., see Patent Document 5) are known.
Furthermore, a mascara container (see, for example, Patent Document 6) that can be scraped off by a squeezing member provided with a horizontal squeezing peripheral piece part attached to the container opening portion of the extra mascara that adheres to the application rod made of a brush member, In order to provide a liquid container that prevents the iron body from curling and deforming when the application shaft is attached and detached, thereby preventing damage to the application shaft and the like, and that the iron body can withstand repeated application and removal of the application shaft. The ironing body is formed into a substantially cylindrical shape with a flexible material, and gradually decreases in diameter from the upper end to the lower part, and gradually increases in diameter from the lower part to the lower end, and There is known a liquid container (see, for example, Patent Document 7) that contains a content liquid such as a mascara formed by cutting a plurality of slits in a vertical direction on a peripheral wall of an ironing body.

  However, in the application container 4 shown in FIG. 9 (b), when removing the cap 3a and taking out the application part 3c, the liquid material such as mascara liquid attached to the application part 3c is squeezed out to some extent by the wiping member 4a. In the wiping member 4a of this structure, the opening (edge part) of the wiping member 4a is caught in the gap of the spring member, and the spring member is compressed when passing through the gap between the spring members. There is a problem that the wiping member 4a bites into the spring member as the tip is inserted and a force is applied, and a large force is generated, and the spring member is easily broken or cannot be pulled out. Moreover, although this subject is easy to enter into the gap of the spring member depending on the shape of the wiping member 4a, that is, the direction of the opening, there is a difference between when the application portion 3c is pulled out and when it is inserted.

Further, in the case of a coating container in which the skirt-shaped coating liquid restricting cylinder described in Patent Document 5 is provided at a substantially right angle toward the spring member, the horizontal ironing peripheral piece portion described in Patent Document 6 is provided. In the application container provided with the squeezing member, when the spring member is used instead of the brush member in the application part, both of the spring members are removed in the same manner as described above when the application part made of the spring member is pulled out or inserted. The edge part of the coating liquid restricting cylinder or the tip part (edge part) of the ironing peripheral piece is caught in the gap, which causes a problem that the spring member is easily broken or cannot be pulled out.
Furthermore, the inner diameter of the wiping member 4a of Patent Document 4 above, the skirt-shaped coating liquid limiting cylinder described in Patent Document 5 above, and the horizontal ironing peripheral piece portion described in Patent Document 6 above is the outer diameter of the spring member. If it is set larger than the above, the above-mentioned problem will occur less frequently, but the application part must always be aligned with the center of the ironing part and cannot be inserted or removed. Trouble that bites into the spring occurs.
Furthermore, in the ironing body described in the above-mentioned Patent Document 7, flexibility is provided by a slit, and when the ironing body having this shape is used for a spring type application part, the slit part cannot be ironed. However, there is a problem that the content liquid such as mascara remains in a streaky shape on the application part and shaft of the spring, and is unsuitable for a spring type application container.
