Description

[Detailed explanation of the invention] "Industrial application field" This invention is designed to store liquid cosmetics, etc. in a container body, and apply the cosmetics, etc. with a brush-shaped part attached to the container body. The present invention relates to a liquid container with an application section provided.

``Prior art'' A brush shaft is suspended inside the container from the back of the top wall of the cap screwed onto the neck of the container, the brush tip attached to the lower end of the brush is soaked with the liquid inside the container, and the cap is removed. It is known that the cap is used as a handle to apply liquid from the tip of the brush.

``Problems to be Solved by the Invention'' With the above-mentioned conventional brushes, when attaching and detaching the cap to the container body, the brush had to be inserted into the container body and then pulled out, making it troublesome to attach and detach the cap.

The present invention is designed to eliminate the above-mentioned drawbacks and to make the operation for liquid application extremely simple.

"Means for Solving the Problem" A container body 1 that stores a weight ball 3, a lower end of a shaft cylinder part 5 is fitted to the outer surface of the mouth and neck of the container body, and an applicator part 6 is erected from the upper end of the shaft cylinder part. A cylinder 9 with an opening at the bottom is fitted into the brush-shaped portion 4 and the inner surface of the mouth and neck portion of the container body or the inner surface of the shaft tube portion 5, and the upper end of the outflow tube portion 10 rising from the upper end of the cylinder is connected to the upper end of the shaft tube portion 5. It fits into the inner surface of the cylinder, and there is a split groove 11 in the lower part of the cylinder.
A cylinder member 8 is provided with an inward flange 12 on the inner surface of the cylindrical shaft portion, a piston portion 14 is fitted into the cylinder, and a piston rod 15 rising from the piston portion is fitted into the cylindrical shaft portion. , and a sliding member 13 that engages an outward flange 16 attached to the piston rod with the upper surface of the inward flange and urges it downward, and when the sliding member is at its lower limit, the upper part of the groove 11 is The inside of the container and the inside of the cylinder are communicated, and when the container is turned upside down and shaken, the weight ball 3
The piston part is pushed into the cylinder by the impact, and the discharge valve 18 formed by the above-mentioned inner and outer flanges 12, 16 opens, and the liquid in the cylinder that has passed through the discharge valve passes through the outflow cylinder part and is absorbed into the application part 6. It was formed to look like this.

"Operation" When the cap 19 is removed and the container body 1 is shaken in an inverted or tilted state, the weight ball 3 hits the lower end surface of the piston.The piston part is pushed into the cylinder 9 by the impact, and the piston part Since the piston rod 15 that stands up is also pushed into the outflow cylinder part 10, the discharge valve 18 formed by the inner and outer flanges 12 and 16
is opened and the liquid in the cylinder is forced into the outflow cylinder part 10. Next, the sliding member 1 is moved by the spring 17.
3 is pushed back and the discharge valve 18 is closed again. The liquid that has entered the outflow cylinder section 10 is absorbed by the application section 6 such as a brush tip, and can be applied.

``Example'' 1 is a container body with a mouth and neck part 2 standing up from the upper end of the body, and a coating liquid and a weight ball 3 are stored in the container body.

The lower end of the cylindrical portion 5 of the brush-shaped portion 4 is screwed onto the outer surface of the mouth neck of the container body, and an applicator portion 6 such as a brush tip is erected from the upper end of the cylindrical portion. The lower end surface of the application section is exposed inside the cylindrical shaft section, and a liquid outflow pipe 7 may be held on the lower axis of the application section with the lower end surface opened into the cylindrical shaft section.

A cylinder member 8 is fitted into the shaft cylindrical portion 5 . The member is inserted from the upper end of the cylinder 9, which has an opening on the lower surface and is fitted to the inner surface of the container mouth neck or the inner surface of the shaft cylinder part.
An outflow cylindrical portion 10 having a smaller inner diameter than the cylinder is erected, and the upper end of the outflow cylindrical portion is fitted into the inner surface of the upper end of the shaft cylindrical portion. A groove 11 is bored in the lower part of the cylinder, and an inward flange 12 is attached to the inner surface of the lower part of the outflow cylinder.

A sliding member 13 is slidably mounted within the cylinder member. This member has a piston rod 15 erected from the upper end of the piston part 14 fitted into the cylinder, and the piston rod is loosely inserted into the outflow cylinder part 10, and the piston rod has a diameter smaller than the inside diameter of the outflow cylinder part. An outward flange 16 with an outer diameter is attached,
The lower surface of the outward flange is engaged with the upper surface of the inward flange. The sliding member is a spring 17
The inner and outer flanges 12 and 16 form a discharge valve 18 due to this force. At the lower limit position of the sliding member due to this bias, the upper part of the outer peripheral surface of the piston part is located in the lower part of the cylinder 9, and the split groove 1
The inside of the container body and the inside of the cylinder 9 communicate with each other through the upper part of the cylinder 9 . The lower end of the piston is preferably allowed to hang down below the cylinder in order to facilitate the impact with the weight ball, and the outer diameter of the lower end of the piston is increased as shown in the figure 14a.
It's good to let them do it.

A cap 19 is airtightly fitted onto the outer surface of the aforementioned shaft cylinder portion 5 to prevent the application portion 6 from drying out.

``Effect of the invention'' Since the lower end of the brush-shaped part 4 is fitted into the mouth neck of the container body, and the application part 6 of the brush-shaped part is provided so that the liquid inside the container can be applied, the brush shaft can be suspended from the top wall of the cap. The liquid application operation is not troublesome as in the case where the liquid is applied, and by shaking the container body upside down or tilted, the weight ball 3 inside the container pushes the piston part into the cylinder 9.
At this time, the discharge valve 18 is opened so that the liquid in the cylinder passes through the outflow cylinder part 10 and is absorbed into the application part 6, so it is easy to replenish the liquid in the application part when it becomes low. It has a discharge valve 18,
Since the discharge valve is provided so as to open only when the container body is shaken by the urging force of the sliding member, there is no inconvenience caused by excessive supply of liquid to the application section.
