Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an improvement in a coating container used to house correction fluid, ink, and liquid cosmetics.

(Prior Art) Conventionally, in this type of container, the container body is made of a flexible material, such as a synthetic resin material, and the application body is housed at the tip via a spring that urges the application body outward. While pressing the container body, the tip of the applicator is immersed against the spring force of the spring, and the applicator liquid flows out through the gap to perform application or writing.

(Problem to be solved by the invention) However, since the above-mentioned conventional method adjusts the operation of the valve by the elastic force of the spring, if the pressure on the container body and the application body immersion into the container body are too strong, Excess coating solution flows out, and if the coating is too weak, the coating may not be sufficiently applied, and it is difficult to adjust the amount, making it impossible to flow out an appropriate amount. Therefore, this invention is an improvement over the conventional one, and is designed to always ensure that an appropriate amount of the coating liquid flows out.

(Means for Solving the Problem) To achieve this, an inner cylinder is provided on the rim of the tip of the container main body with an outlet at the rear, and a flexible packing having a hole in the center and radial slits around the hole is inserted into the head. The applicator is fitted into the head, and the applicator is housed in the head, and the applicator has its tip valve part abutted against the inner wall of the head, the tip can be retracted and retracted from the opening at the tip of the head, and the applicator has an outer periphery of the applicator. A collar body is provided, and this collar body has a rear end surface that closes the center opening of the seal on the front surface of the seal when the tip valve portion is in contact with the seal, and the outer diameter of the collar body is equal to or smaller than the center hole of the seal. It has a larger diameter so that it can move through the center hole of the packing, and a spring is fitted between the collar and the inner bottom surface of the inner cylinder.

(Function) With the above structure, when applying, when the container body is gripped and the protruding tip of the applicator is pressed against the application surface, the applicator will sink into the container body against the spring force. However, the contact between the inner wall of the container body and the tip valve portion of the applicator separates, forming a gap for the application liquid to flow out. At the same time, the flange of the applicator spreads the central hole of the packing of the flexible body and the slit of the packing, bends the packing rearward, and moves rearward. Thereafter, when the applicator passes through the central hole and slit of the gasket and returns to the front, its movement and the restoring force of the gasket guide a predetermined amount of the application liquid stored in the inner cylinder into the head. be. In this way, the application liquid can be temporarily stored in the inner cylinder and then guided into the head to replenish the predetermined amount. The central hole is closed by the contact of the end faces, and the valve portion at the tip of the applicator comes into contact with the inner wall of the head, thereby preventing leakage to the outside.

(Example) This invention will be explained in more detail with reference to an example shown in the drawings. Reference numeral 1 denotes a container body, which is made of metal or a rigid material, and contains therein a coating liquid such as a correction coating liquid, writing ink, liquid cosmetics, etc., and may include a small container for stirring the coating liquid. Contains a ball. Further, the container body 12 can be made of a flexible material such as synthetic resin, and in this case, the central portion can be pressed to cause the coating liquid to flow out from the tip of the coating body. 2 is the container body 1
This is a head that fits into the tip opening, and in FIGS. 1 to 3 showing the first embodiment, an annular first step 16 and a second step 17 are provided on the inner wall of the head 2, respectively. An annular flange 6 provided on the outer periphery of the inner tube 3 is sandwiched between the first step section 16 and the opening edge of the inner tube 3, and a ring-shaped collar 6 provided on the outer periphery of the inner tube 3 is sandwiched between the first step section 16 and the opening edge of the inner tube 3. The elastic packing 5 is clamped.

The inner cylinder 3 is provided with an outlet 8 at its rear inner bottom, which communicates with the coating liquid storage section of the container body 1. On the other hand, the packing 5 has a central hole 14, a radial slit 15 is formed on the periphery of the central hole 14, and an annular flange 7 (in the first embodiment) that passes through the central hole 14 and is provided on the outer periphery of the application body 4. When the slit 15 is moved, the slit 15 is pushed open so that the slit 15 can be moved rearward. That is, the collar body 7 has a larger diameter than the center hole 14 of the packing 5 and is large enough to be able to move through the center hole 14. The radial slits 15 may be slits 15' as shown in FIGS. 5A and 5B, and any number of slits 15' may be provided.

The applicator 4 normally has its tip 11 protruding from the tip hole 18 of the head 2 due to the spring 10 inserted between the collar body 7 and the rear inner bottom surface of the inner tube 3, and the tip valve portion 13 is It elastically abuts against the inner wall of the head 2 to prevent the coating liquid from flowing outward, and at the same time abuts the center hole 14 of the gasket 5 against the rear end surface of the flange 7 to establish communication with the inside of the inner cylinder 3. Obstruction.

Since the first embodiment is configured as described above, when the tip portion 11 of the applicator body 4 is pressed against the coating surface during coating, a gap is formed in the tip valve portion 13, and the correction fluid in the head 2 is removed. The application liquid for one press flows out, and for example, one drop of correction liquid is dripped onto the correction area with each press to erase that area, and at the same time, it is stored in the inner cylinder 3. Apply the coating liquid to
The restoring operation of the gasket 5 causes the application liquid to flow out in a predetermined amount and replenish the head 2 from the inner cylinder 3.

When the container body 1 is made of a flexible material, the pressure of the body 1 allows continuous application over a relatively long period of time.

In addition, in FIG. 2, the tip 11 of the applicator 4 is connected to the head 2.
It shows a state in which the flange body 7 is pushing and expanding the slit 15 of the packing 5, and the third
The figure shows a state in which the collar body 7 is retreated behind the gasket 5 and the coating liquid is flowing out. The cut around the center hole 14 of the packing 5 faces rearward as shown in Figure 6A, and may have a large diameter 19 or a small diameter 19' as shown in B (the arrow indicates the direction of the tip). In case 2, it is easy to move the applicator 4 when returning, and in case 2, it is easy to operate the applicator 4 when pressing.

FIG. 4 shows a second embodiment, in which the first step 16 and the second step 17 of the first embodiment provided in the head 2 are made into one step 18, and the inner cylinder is arranged in accordance with this. 3
An annular flange 6 is provided on the opening edge of the main body 1, and the annular flange 6 and the packing 5 are sandwiched between the opening edge of the main body 1 and the stepped portion 18 to simplify the structure.
A plurality of outflow ports 8 are provided at the rear inner bottom. Other configurations and operations are similar to those of the first embodiment.

(Effect of the invention) As described above, the application liquid is stored separately in the inner cylinder and the head, and the space between them is partitioned by a flexible packing provided with a slit, which is provided in the application body. As it passes through the collar body, a certain amount of coating liquid is stored in the head by the restoring force of the collar body and the bent packing, and when used, an appropriate amount of coating liquid from the head is allowed to flow out, thereby reducing the drop-off. It has an excellent effect of preventing fading and allowing smooth application.
