Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a makeup applicator, and more specifically, the applicator can be removably attached to a support, and the applicator can be easily replaced. Moreover, the present invention relates to a makeup applicator to which the applicator is securely attached.

[Prior Art] Conventionally, various devices have been devised as this type of makeup applicator. For example, a brush composed of a bag-shaped brush body, a support having a sandwiching piece at the base, and a handle having engaging holes that engage with the protrusions of the sandwiching piece (Japanese Utility Model Publication No. 51-47912), center A cosmetic applicator consisting of a substantially elliptical frame-shaped elastic mounting part with a hole in it, a handle bar, and a bag-like sliding contact brush (Japanese Utility Model Publication No. 53-24438). There is a cosmetic writing tool (Japanese Utility Model Publication No. 61-38499), which is composed of a brush tip support having an insertion piece on its bottom and a handle having an insertion hole at its tip.

[Problems to be Solved by the Invention] However, the brush disclosed in Japanese Utility Model Publication No. 51-47912 has a drawback that it is not easy to replace the brush body due to the complicated support and handle structure. See you again
In the cosmetic applicator disclosed in Japanese Patent No. 53-24438, when the bag-shaped sliding contact brush is removed from the brush holder, the sliding contact brush is grasped with a fingertip and lightly pulled, and the engaging protrusion of the brush holder and the sliding contact brush. However, in some cases, the sliding contact brush is deformed in the same manner as the brush holder and cannot be removed properly. There is also a drawback that the brush holder easily comes off from the handle during replacement. Next, in the makeup pen of JP-B No. 61-38499, when the brush body is to be replaced, only the brush body cannot be replaced, and it is necessary to replace it together with the brush tip support. It was economical.

As described above, it has been desired to provide a makeup applicator in which the applicator can be replaced more easily and the applicator is securely mounted.

[Means for Solving the Problem] The present inventor has devised the present invention as a result of earnest studies in view of the above points.

That is, the present invention is a makeup applicator comprising a bag-shaped applicator and a support, wherein the applicator attachment part is formed at one end of the support, and the shape memory substance is provided on both sides of the applicator attachment part. A leaf spring is formed so that the applicator is clamped by the leaf spring made of the shape memory substance at the applicator mounting portion at a certain temperature or lower, and the holding force of the leaf spring made of the shape memory substance is released at a predetermined temperature or higher. A makeup applicator characterized by being formed as described above.

[Operation] Since the present invention is configured as described above, in order to replace the applicator, first the leaf springs made of the shape memory substance formed on both sides of the support are heated to a certain temperature or higher, for example, 50 ° C. or higher. To do. Then, the leaf spring made of the shape memory substance changes to a state (bent shape) in which the application body of the application body mounting portion is not held, which is a memory state. The applicator can then be removed from the applicator mount and replaced with a new applicator. When the shape memory material leaf spring is cooled to a predetermined temperature or lower, for example, room temperature, the shape spring returns to the original linear shape, and the new applicator of the applicator mounting portion is again held.

[Embodiment] The structure of the present invention will be described below with reference to the drawings illustrating an embodiment thereof.

Reference numeral 1 is a bag-shaped applicator, which is sponge elastomer
It is molded from non-woven fabric.

Reference numeral 2 denotes a support, which has an applicator mounting portion 3 formed at one end thereof, to which the bag-shaped applicator 1 is attached.

Reference numeral 4 denotes a leaf spring made of a shape memory material formed at one end of the support body 2 and on both sides of the application body mounting portion 3. The shape memory material leaf spring holds the applicator 1 attached to the applicator attachment portion 3 of the support 2 at a predetermined temperature or lower, for example, at room temperature. Thus, the applicator body 1 is securely attached to the support body 2.

Further, when the shape-memory substance leaf spring 4 is heated to a certain temperature or more, for example, 50 ° C. or more with a dryer or warm water, the state in which the application body 1 of the application body attaching portion 3 in the memory state is not clamped (bending Shape).

The shape-memory substance leaf spring 4 returns to its original linear shape when cooled to a certain temperature or lower, for example, room temperature (whether rapid cooling or slow cooling), so that the applicator 1 can be firmly held. Become.

A shape memory alloy, a shape memory resin, or the like can be used for the shape memory material leaf spring 4 of the present invention. Further, the shape of the shape memory material leaf spring 4 is not particularly limited to a plate shape, a round bar shape, a square bar shape, or the like.

Regarding the processing of the shape memory material leaf spring 4 of the present invention, for example, when using a shape memory alloy leaf spring, nickel
Titanium alloys, copper-zinc, and aluminum alloys can be used, and the martensite transformation start temperature of this alloy can be adjusted by changing the composition.

When designed to have a bent shape at a certain temperature or more and a linear shape at a certain temperature or less, the certain temperature corresponds to the temperature at which the martensite phase of the alloy undergoes reverse transformation to the parent phase. First, a linear alloy is bent to have a bent shape, which is heated to a beta temperature and then rapidly cooled so that the alloy becomes a martensite phase. Here, the bending is extended to form martensite under stress, and the shape memory material leaf spring 4 of the present invention can be obtained.

In the makeup applicator of the present invention, when the applicator 1 is replaced, first the shape memory material leaf spring 4 is heated to a certain temperature or higher to change it into a bent shape. At this time, the applicator body 1 can be easily removed from the applicator mount portion 3 of the support body 2 by pinching it with a fingertip and gently pulling it. Then, a new coating body 1 is attached.

Next, when the shape memory material leaf spring 4 is cooled, the bent shape returns to the original linear shape, so that the application body 1 is firmly sandwiched by the shape memory material leaf spring 4. Thus, the applicator body 1 is securely attached to the support body 2.

[Effects of the Invention] As described in detail above, the makeup applicator of the present invention makes it extremely easy to change the applicator body by controlling the clamping force due to the temperature difference of the shape memory material leaf spring. Further, the applicator can be reliably mounted on the support.
