Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention prevents liquid dripping from a container discharge port, solidification and clogging of discharge residue, and prevents the intrusion of the agent between the finger and the nail while keeping the container in place. The present invention relates to a cosmetic that can discharge an arbitrary amount of content by simply pressing.

[0002]

2. Description of the Related Art Conventionally, cosmetics have been widely used at home and in the barber / beauty industry in dosage forms such as high-viscosity wax, gel, cream, low-viscosity water, oil, lotion, milk and liquid. When the contents have a high viscosity, jar bottles, tubes, etc. are used, but especially in jar bottles, it is not hygienic because the fingers and hands have to touch the inside of the bottle and the contents. In addition, the agent enters between the finger and the nail during use, which causes discomfort. On the other hand, when the content has a low viscosity, it can be ejected only directly from the bottle, such as ejecting as a mist, foam or liquid in a pump type.
In that case, it may be difficult to discharge a very small amount,
Further, if the discharge port is made small to discharge a very small amount, there is a problem such as clogging. Further, there are cases where the container cannot be used unless it is picked up, and there is a case where liquid is dripping from the discharge port.

An upper surface discharge type pump as a container which overcomes the above-mentioned drawbacks when taking out conventional cosmetics, can dispense cosmetics hygienically, quantitatively and easily, has a known remaining amount, and does not drip. There is an up-type container. However, if the content contains a solid substance or a film-forming polymer at 25 ° C. or lower for the purpose of styling the hair, imparting firmness to the skin, and stabilizing the content, the content discharged It is easy for the material to dry and adhere to the discharge surface. If the color of the adhered substance is significantly different from the contents due to drying or the physical properties are changed, it may cause discomfort to the consumer, worsen the usability, and cause clogging, which makes ejection impossible. There is a possibility.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and overcomes the drawbacks of such a top discharge type pump-up type container, and sanitarily, quantitatively and easily discharges cosmetics. Can prevent the solidification of the discharge residue,
An object is to provide a cosmetic that is not clogged and has excellent usability.

Means for Solving the Problems and Embodiments of the Invention As a result of various studies, the present inventors have found that one or two of solid substances and / or film-forming polymers at 25 ° C. or lower.
At least 25% of volatile matter at 25 ° C./24 hours and one or more oily components which are liquid at 25 ° C., and have a high solid-state substance and / or high film-forming property. The present invention has been found to prevent solidification of the contents adhering to the discharge port and prevent clogging of a top discharge type pump-up type container by blending such that the mass ratio of the molecule and the oily component is 20 times or less. Has been completed.

That is, according to the present invention, one or more kinds of solid substances and / or film-forming polymers at 25 ° C. or lower, and a volatile content at 25 ° C./24 hours of 5% or less, and 25
Containing one or two or more oily components at a temperature of ℃,
Further, there is provided a cosmetic characterized in that the solid substance and / or the film-forming substance and the oily component are mixed in a mass ratio of 20 times or less and filled in an upper surface discharge type pump container. . Hereinafter, the present invention will be described in more detail.The container used in the present invention is an upper surface discharge type pump-up container, and the container body should be made of a transparent material or be provided with a transparent slit portion. For example, it is convenient to know the remaining amount of the contents at a glance. HVD (high viscosit)
y dispenser) pump containers and the like.

FIG. 1 is a diagram in which a part of the HVD is cut off.
The overcap 1 is detachably fitted on the outer peripheral surface of the neck of the container. When the overcap 1 is removed, the container head 2 is exposed, and a discharge port 12 is provided in the container head. A liquid reservoir 13 is formed in the central portion of the lower portion of the container head 2 via a path connected to the discharge port 12, and a valve 7 is provided below the reservoir 13. The container head 2 is lifted up to a certain position by a spring 8, and when the container head 2 is pushed downward, the piston 4 is lowered together with the container head 2 and the liquid reservoir 13 is pressed to hold the contents ( The liquid) is discharged from the discharge port 12. When the pressing of the container head 2 is stopped (the pressure is released), the rise of the container head 2 causes the liquid reservoir 13 to become a negative pressure, the valve 7 moves slightly upward, and a gap is formed. The liquid in the container body 9 is sucked from the container and filled in the liquid reservoir 13.
