Description

  The present invention relates to a liquid applicator for applying an impregnated body with a chemical solution, lotion, or other liquid.

Conventionally, as this type of liquid applicator, a cotton ball part provided at the end part of a cotton swab is impregnated with a chemical solution, lotion, or other liquid in advance, and this cotton swab is sealed with a package (for example, Patent Document 1).
Also, a liquid having a small diameter pipe sealed at one end and having the other end as an open end, sealed with liquid in a state of being retracted from the open end side, and formed with a notch on one end side, is sealed in the open end. There is a cotton swab pipe formed by providing a cotton lump in a state of being isolated from the cotton swab, and the cotton swab pipe faces the cotton lump downward and folds the sealed end side of the small-diameter pipe using a notch to ventilate the sealed end side. Thus, the liquid is leached from the open end side and absorbed by the cotton lump (for example, see Patent Document 2).
Furthermore, there is a cotton swab in which the shaft portion of the swab is a straw, a liquid such as a chemical solution is injected into the straw, and one end is completely sealed, and the cotton portion side is sealed with a plug valve. By crushing the plug valve from the outside, the chemical solution is allowed to permeate the cotton part through the crevice of the capped valve (for example, see Patent Document 3).

However, in the case of the above-mentioned patent document 1, since the liquid such as the chemical liquid impregnated in the cotton rest part oozes out and flows freely in the package, the liquid is also applied to the shaft rod that becomes the gripping part at the time of use. Since the liquid adheres to the hand when it is used, it is not easy to use, and the liquid impregnated at the corner cannot be used effectively and is wasted.
Moreover, the thing of patent document 2 has a malfunction similar to the above when the closed end side of a small diameter pipe is folded, and has the same trouble as described above. It must be a material that can be crushed, and because of its lack of rigidity as a shaft, it was extremely difficult to use.

In view of the problem that the usability based on the above-described prior art must be improved, the present invention allows a rod body to be loosely fitted to the cylinder body and to inject the liquid into the gap between the rod body and the cylinder body wall. In addition, a sealing body is provided at both ends of the cylindrical body and sealed, and at least one of the sealing bodies is provided at one end of the rod body, and the one sealing body is a cylindrical body together with the sealing body. It has a push-in portion that can be pushed into the inside and protrudes outside the cylinder, and an application body formed by covering the other end and the other sealing body with a liquid-absorbing material on the other end of the cylinder. In the provided liquid applicator, at least one end of the cylinder main body is provided with a reduced diameter portion having a smaller diameter than the cylinder main body to form a cylinder, and the one sealing body is fitted into the opening of the reduced diameter portion, and the sealing is performed. The outer diameter of the pushing part of the stationary body is made smaller than the inner diameter of the reduced diameter part, and the length of the pushing part that can be pushed in and inserted is the entire diameter of the reduced diameter part. By you to configure more long, the push portion a cylindrical body inside the pushing of one of the sealing body, removed by pressing the other sealing body by rod the other end, to release the sealed state of the other end, The above-described problem is solved by allowing the liquid to be impregnated into the application body.

  In short, the present invention provides a cylindrical body with a rod that is slightly shorter than the cylindrical body, and injects the liquid into the gap between the rod body and the wall of the cylindrical body, and seals at both ends of the cylindrical body. And at least one of the sealing bodies is provided at one end of the rod body, and the one sealing body has a pushing portion that can be pushed into the cylindrical body together with the sealing body. Since the coated body formed by covering the other end and the other sealing body with a liquid absorbent material is provided on the other end side of the cylindrical body, By simply pushing the pushing part into the cylinder, the other sealing body is pushed out of the cylinder via the rod, the sealed state is released, and the liquid soaks into the application body by the capillary action of the liquid-absorbing material. Therefore, it is possible to prepare for use very easily without getting any hands dirty.

  At least one end of the cylinder body is provided with a reduced diameter portion having a smaller diameter than the cylinder body to form a cylinder, and the one sealing body is fitted to the reduced diameter portion, and the outer diameter of the pushing portion of the sealing body is set. The diameter is further reduced from the inner diameter of the reduced diameter portion, and the length of the push-in portion that can be pushed in is set to be longer than the entire length of the reduced diameter portion, so one sealing body is pushed into the large diameter portion on the center side of the cylinder. As a result, the sealed state is also released at one end side, and a ventilation gap is formed between the pushing portion and the inner wall of the reduced diameter portion, and the gap portion into which the liquid has been injected is opened to the atmosphere. When the body is down, the liquid flows down by natural fall and soaks into the coated body without any remaining, so it is very easy to handle and easy to use.

  Since the cross-sectional shape in the radial direction of the indented portion is not similar to the cross-sectional shape in the radial direction of the reduced-diameter portion, for example, if the reduced-diameter portion is cylindrical, the cross-sectional shape of the indented portion is a cross-shaped or triangular shape If a polygonal shape is used, a large ventilation gap can be formed between the indented portion and the inner wall of the reduced diameter portion so that the liquid can flow more smoothly, and the indented portion does not have to be excessively small in diameter. Furthermore, it is possible to further improve the usability while ensuring sufficient strength.

  The product of the present invention is characterized by the fact that the rod body is housed together with the liquid inside the cylinder body, so that the amount of injected liquid is smaller than the internal volume of the cylinder body itself, but the cross-sectional shape of the rod body in the radial direction is reduced. Since the cross-sectional shape in the radial direction and the non-similar shape, by combining the cross-sectional shape of the rod body and the cylindrical body in the same manner as described above, the gap between the rod body and the cylindrical body wall is increased to ensure the capacity, A sufficient amount of liquid necessary to wet the coated body can be injected and prepared, and as with the above-mentioned pushing portion, the rod body strength is improved and the sealed state on the other end side is ensured. Can be canceled.

  In the coating body on the other end side, the retraction gap of the other sealing body is provided in the periphery of the other end of the cylindrical body inside the coating body, so that the sealing body pushed by the rod body retreats to the retraction gap, so that Since it is easily removed from the other end of the cylinder, the sealed state on the other end side can be more reliably released.

Since a thin film made of waterproof paper or plastic film is attached to the other end of the cylinder to make the other sealed body, it is pushed by the rod by pushing the pushing part into the cylinder. Since the thin film is torn and torn, there is no risk of a sealing plug release failure at all.

  Since the application body is also provided on one end side of the liquid applicator, for example, the liquid is used as a disinfectant, and the disinfectant liquid is infiltrated into the application body at the other end and applied to the affected area. Disinfecting solution that has been wiped off and applied in excess can be removed, and the liquid is used as a manicure remover, and the manicure is dissolved by applying the remover to the nail with the application body at the other end. It can be removed cleanly by the body, or when the affected area is wet or dirty before application, after removing moisture and dirt with the application body at one end, the chemical solution can be applied with the application body at the other end. However, it can be used in various ways depending on the liquid selection and the situation.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 to 14, the liquid applicator of Example 1 is formed with a cylindrical body 3 by providing a reduced diameter portion 2 having a smaller diameter than the cylindrical main body 1 at one end (left end in the drawing) of the cylindrical main body 1. The rod body 4 is loosely fitted to the cylindrical body 3 so that the liquid L is injected into the gap 5 between the rod body 4 and the inner wall of the cylindrical body 3.
The rod body 4 is provided with a sealing body 6 at the left end thereof, the sealing body 6 is fitted into the left end opening of the reduced diameter portion 2, and on the other end (right end in the drawing) side of the cylindrical body 3. The other sealing body 6a is fitted into the opening.
That is, both ends of the cylinder 3 are sealed with the sealing bodies 6 and 6 a so that the liquid L is sealed inside the cylinder 3.

  The liquid L is appropriately selected according to the application of the liquid applicator. For example, a chemical solution such as iodine tincture, a disinfectant solution such as oxidol, and other purified water, organic solvent, baby oil, lotion, and a light removing solution. Is mentioned.

  The sealing body 6 is provided with a rod-shaped pushing portion 7 that can be pushed into the inside of the cylinder 3 together with the sealing body 6 in a state of projecting to the outside of the cylinder 3. The diameter is set to be smaller than the inner diameter of the reduced diameter portion 2 and the length of the push-in portion 7 that can be pushed in is set to be longer than the entire length of the reduced diameter portion 2. A stopper portion 8 having a diameter larger than 2 is provided.

On the other hand, the right end side of the cylindrical body 3 is provided with an application body 9 formed by covering the right end and the sealing body 6a with a liquid absorbent material. Examples of the liquid absorbent material include absorbent cotton and nonwoven fabric. In addition, foamed resins such as foamed polyurethane, foamed polystyrene, and foamed synthetic rubber may be used.
In addition, a retreating gap 10 for the sealing body 6a is provided inside the application body 9 and around the right end of the cylindrical body 3.

  The cylindrical body 1 and the reduced diameter portion 2, the rod body 4 and the push-in portion 7 are formed so that the rod body 4 and the push-in portion 7 are not made thinner than necessary, and sufficient strength is ensured while the tubular body 1 and the rod body are secured. 4 and the radial cross-sectional shape of the rod body 4 and the push-in portion 7 in the radial direction of the cylindrical body 1 and the reduced-diameter portion 2 in order to widen the gap between the reduced-diameter portion 2 and the push-in portion 7. For example, as in this embodiment (see FIGS. 4 to 7 and FIGS. 11 to 14 in particular), for example, when the cylindrical body 1 and the reduced diameter portion 2 are cylindrical, The rod body 4 and the push-in portion 7 may be in a cross shape, and may be a triangle or a star.

At the time of use, the pusher 7 is pushed in until the stopper 8 comes into contact with the left end of the cylindrical body 3 (reduced diameter portion 2), as shown in FIGS.
Then, the sealing body 6 passes through the reduced diameter portion 2 and comes off to the large diameter portion (that is, the cylinder main body 1) on the center side of the cylinder 3.
At this time, since the pushing portion 7 has a smaller diameter than the reduced diameter portion 2 and has a cross-sectional shape of a cross, a ventilation gap 11 is formed between the pushing portion 7 and the inner wall of the reduced diameter portion 2. Since the sealing body 6 has a smaller diameter than the cylinder main body 1, there is a gap between the sealing body 6 and the cylinder main body 1, and the left end of the gap portion 5 into which the liquid L has been injected enters the atmosphere via the ventilation gap 11. Opened.
On the other hand, as shown in FIGS. 8 and 10, the sealing body 6a at the right end of the cylindrical body 3 is pressed against the right end of the rod body 4 and is detached from the cylindrical body 3 and retracts into the retreating gap 10, and the application body 9 is ventilated. Therefore, even at the right end, the gap 5 is opened to the atmosphere. As a result, the pumping force by the capillary action is lost, and the liquid L flows by natural fall and is absorbed by the application body 9.

  Incidentally, the retracting gap 10 is not always necessary, and may be unnecessary depending on various conditions such as the shape of the sealing body 6a and the elasticity of the application body 9. In short, the sealing body 6a is provided at the right end of the rod body 4. Since it may be pushed and incomplete, it may be removed from the cylinder 3 so that there is a gap and the opening at the right end of the cylinder 3 is opened to the atmosphere.

As shown in FIG. 15, the liquid applicator of Example 2 has a thin film deposited on the right end of the cylinder 3, and this thin film is used as a sealing body 6a. Other configurations are the same as those of Example 1. is there.
The thin film 6a only needs to be capable of sealing the liquid L and has a durability to the extent that it can be torn by being pressed by the rod 4. Examples include thin paper and plastic film.

  Also in the present embodiment, the liquid applicator having the retracting gap 10 is illustrated in the drawing, but in the case of this liquid applicator in particular, if the applying body 9 made of a material having excellent elasticity such as sponge is used, the retracting gap 10 In this case, when the thin film 6a is broken, the application body 9 comes into contact with the opening at the right end of the cylinder 3, so that the application body 9 can be obtained even if the left end of the cylinder 3 is not opened to the atmosphere. Since the liquid L is sucked into the application body 9 by the capillary action acting on the cylinder 3, the reduced diameter portion 2 at the left end of the cylindrical body 3 may be omitted.

As shown in FIG. 16, the liquid applicator of the third embodiment covers the stopper portion 8 with a liquid-absorbing material to provide another applicator 9 a, and the other configuration is the same as that of the first embodiment.
At the time of use, for example, the liquid L is soaked into the application body 9 and applied to the application part, and then the application part is wiped with a dry application body 9a to remove excess liquid L, or the application part Then, the liquid L is applied by the application body 9.

  As shown in FIG. 17, the liquid applicator of Example 4 is provided with an application body 9 that covers the left end of the cylindrical body 3, the pushing portion 7 and the stopper portion 8 of the sealing body 6 with a liquid-absorbing material, Other configurations are the same as those of the first embodiment.

  As shown in FIG. 18, the liquid applicator of Example 5 is provided with a reduced diameter portion 2 having a diameter smaller than that of the cylindrical main body 1 at both ends of the cylindrical main body 1 to form a cylindrical body 3. The sealing body 6 having the pushing portion 7 and the stopper portion 8 is fitted, and each end portion of the cylindrical body 3, the pushing portion 7 and the stopper portion 8 are covered with the liquid absorbing material, and the application body 9 is applied to both ends. The other configurations are the same as those of the first embodiment.

If the application body 9 is excellent in elasticity, not only the stopper portion 8 but also the end portion of the cylindrical body 3 and the pushing portion 7 may be covered with the liquid absorbing material as in Examples 4 and 5, However, the pushing-in part 7 and the liquid absorbing material must not be fixed.
Whether or not the liquid L is soaked only by the application body 9 on one side during use or if it is soaked by both may be appropriately selected as desired.
