Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a knock-type pen-shaped liquid container used as a stationery, a manicure cosmetic, and the like.

"Prior Art" This type of conventional one has a brush tip or other application portion attached to the tip of the brush shaft, and a liquid container body for accommodating ink or cosmetic liquid that can be pushed into the brush shaft. The system is basically provided with a seal mechanism at the mouth of the liquid container body and pushing the liquid container body into the brush shaft against the return spring to open the seal mechanism and supply the liquid to the coating portion.

"Problems to be solved by the device" This type of container requires a slide, a seal, a return mechanism, and the like, and thus has a large number of parts, which makes assembly difficult and costly.

The present invention is to obtain a knock-type pen type liquid container in which the number of parts is reduced, the assembly is simplified, and the cost is reduced.

"Means for Solving the Problem" The application part 7 is fitted into the holding cylinder 8 held by the inwardly projecting wall parts 19 attached to the lower ends of the main cylinders of the upper opening and the upper end of the holding cylinder 8 is held. Through the upward step, a brush shaft 1 in which a guide cylinder 9 having a cylindrical piston 9a at the upper end is erected, and a lower part of a sliding cylinder 12 is watertightly and vertically slidably fitted on the outer surface of the cylindrical piston 9a. And the mouth member 3 in which the peripheral wall 10 is erected from the intermediate portion of the outer surface of the sliding cylinder through the outward flange-shaped wall 11,
A lower part of the cylinder wall is fitted on the outer surface of the upper part of the sliding cylinder 12, and a plurality of liquid flow holes are formed in an inward flange wall 13 attached to the upper end of the cylinder wall.
An outer plug 15 having a hole 14 formed therein and an outer flange 15 having an upper end portion of a rod portion vertically slidably fitted in a flange hole of the inward flange wall 13 and attached to an intermediate portion of the rod portion. A plurality of notched grooves 17 are vertically provided on the surface, and the lower surface of the outward flange portion inside the notched grooves is brought into close contact with the upper end of the sliding cylinder 12 and is attached to the outer surface of the rod body below the outward flange 15. A plurality of engaging plates 23 fitted to the inner surface of the upper portion of the sliding cylinder 12 and the upper end of the mouth / neck portion 20 fitted to the inner surface of the peripheral wall 10 to erect the body portion, and the upper portion of the body portion A liquid storage container body 2 having a portion 2a protruding from an upper end opening of the main cylinder portion, and the inwardly projecting wall
19 A return spring 6 interposed between the upper surface and the lower surface of the outward flange-shaped wall 11 and a compression spring 16 interposed between the upper surface of the outward flange 15 and the lower surface of the inward flange-shaped wall 13 Therefore, the distance between the upper surface of the upper end of the upper end of the holding cylinder 8 and the lower end of the sliding cylinder 12 is made larger than the distance between the upper end of the cylindrical piston 9a and the lower end of the engaging plate 23.

[Operation] When the upper end portion 2a of the liquid storage container body 2 is pushed in against the elasticity of the return spring 5 from the state shown in FIG. 1, the liquid storage container body 2, the mouth member 3, the inner plug 4, and the floating movement. When the stopper 5 is pushed down with respect to the brush shaft 1 and the lower end of the engaging plate 23 of the floating stopper 5 comes into contact with the upper end of the cylindrical piston 9a of the guide cylinder 9, the lowering of the movable stopper 5 is stopped, and the liquid is stored from this state. When the container body 2 is further pushed in, as shown in FIG. 2, the liquid container body 2, the mouth member 3 and the inner plug 4 are lowered with respect to the floating plug 5, and the upper end of the sliding cylinder 12 is exposed. The fluid in the liquid-storing container body 2 separates from the lower surface of the facing flange 15 and allows the fluid to flow through the liquid circulation hole 14, the notch groove 17, the gap between the upper end of the sliding cylinder 12 and the lower surface of the outward flange 15, and the inside of the guide cylinder 9. It is then supplied to the coating unit 7.

When the pushing down of the liquid storage container body 2 is released from this state, the liquid storage container body 2, the mouth member 3, and the inner plug 4 are moved relative to the floating plug 5 and the brush shaft 1 by elastic recovery of the return spring 6. Rise,
