Description

  The present invention relates to a cap body in an application container with a comb that regulates hair contact with an application body exposed at the upper end while adjusting the contact with comb teeth arranged outside the exposed application body.

  A liquid-absorbing applicator, such as sponge or felt, is installed in a container body containing a coating solution such as hair dyeing solution, protruding from the upper end, and the outside of the protruding applicator. A comb-equipped coating container in which comb teeth are disposed is known.

In this comb-coated container, the application body impregnated with the application liquid is directly brought into contact with the hair to achieve application of the application liquid to the hair. Therefore, the amount of the application liquid applied to the hair is determined by the amount of the application liquid applied to the application body. The hair is properly controlled according to the impregnation pressure of the hair, and the hair contacting the coated body is arranged with comb teeth to regulate the contact posture, so the coating form of the coating solution on the hair is always stable and constant, and further applied. Since the comb teeth are positioned outside the body so as to cover the application body, the application body is reliably prevented from coming into contact with the scalp.
JP-A-11-169224

  However, in the above-described prior art, since the upper end portion of the application body having a relatively large surface area is exposed from the inside of the container body, the application body is in a state where the container body is sealed with the cap body. The amount of the coating liquid that evaporates from the inside of the cap body is large, and the coating liquid evaporated from the coating body condenses on the inner surface of the cap body. There is a problem in that the surface of the container main body is soiled by moving down to the container main body side.

  In addition, the coating liquid evaporated in the cap body is less likely to condense on the inner surface of the cap body by repeating evaporation and condensation from the coated body as long as there is no change in the environmental temperature of the comb-equipped coating container. When the environmental temperature of the application container changes, the cap body receives this temperature change, and when the environmental temperature rises, heat is transferred to the application body through the space inside the cap body, the coating liquid evaporates, and the environmental temperature decreases. There is a problem that condensation of the evaporated coating liquid on the inner surface of the cap body is promoted.

  Therefore, the present invention was devised in order to solve the above-described problems in the prior art, and makes it difficult for the coating liquid condensing on the inner surface of the cap body to move out of the cap body, and to prevent the coating liquid vapor from flowing into the cap body. An object of the present invention is to make it difficult for condensation on the surface to occur, and to prevent the occurrence of contamination due to the coating liquid condensed on the inner surface of the cap body.

Among the present invention for solving the above technical problems, the means of the invention according to claim 1 is:
A bottomed cylindrical container body containing the coating liquid, a liquid-absorbing application body that is assembled to the container body in a protruding state from the upper end and leads out the coating liquid, and is disposed outside the protruding application body. A cap body for a comb-equipped application container having a plurality of comb teeth provided;
Covering the entire combination of the coated body and comb teeth projecting from the upper end of the container body, the outer cap with a crested cylindrical shape that is detachably assembled to the container body, and the outer cap is tightly embedded in the container body. It is composed of a cap-shaped cylindrical inner cap made of a soft elastic material that functions as a packing by tightly fitting,
Forming a large number of irregularities on the inner surface of the top wall of the inner cap;
It is in.

  In the first aspect of the present invention, the cap body is composed of the outer cap that constitutes the functional unit that can be attached to and detached from the container body, and the inner cap that functions as a packing. Thus, a strong and stable attaching / detaching operation can be obtained, and the sealing of the container body by the cap body can be stably and strongly achieved.

  In addition, since many irregularities are formed on the inner surface of the inner wall of the inner cap that forms the inner surface of the cap body, the inner surface of the inner wall of the inner wall of the inner cap becomes severely irregular, which greatly increases the surface area. It is in a state.

  Therefore, when the vapor of the coating liquid in the cap body is condensed on the inner surface of the top wall of the inner cap in a sealed state by the cap body of the container body, the condensed coating liquid is extremely The contact is made with a large contact area, and therefore, it strongly adheres to the inner surface of the top wall of the inner cap and hardly moves out by dripping or the like.

  Further, since the cap body has a double wall structure of the outer cap and the inner cap, the cap body exhibits a high heat insulating action, and thereby the internal space of the cap body that seals the container body, that is, the coating liquid vapor is generated. The thermal effect of the environmental temperature of the application container with a comb with respect to the space where it is located will be weakened.

  The invention described in claim 2 is the configuration of the invention described in claim 1, with the addition that the unevenness is formed by providing a recess on the inner surface of the top wall of the inner cap.

  In the invention according to claim 2, the top wall portion of the inner cap provided with the concave portion is exhibited by the wall thickness being smaller than the other wall portion of the inner cap by the amount of the concave portion formed. Since the heat insulation action becomes small, it becomes more susceptible to the thermal effect of the environmental temperature, and therefore, when the coating liquid vapor in the inner space of the cap body condenses, prior to other parts of the inner cap inner surface, Condensation always occurs in this recess.

  The invention according to claim 3 is the structure of the invention according to claim 2, wherein a recess is formed in substantially the entire inner surface of the top wall of the inner cap, and a plurality of protrusions are provided in the recess to form an unevenness. It is a thing added.

  In the invention described in claim 3, since the recess is formed in a wide range of the inner surface of the top wall of the inner cap, the substantially entire area of the inner surface of the top wall of the inner cap functions as a dew condensation functional part. Become.

  The invention described in claim 4 adds to the configuration of the invention described in claim 2 that the concave and convex portions are formed by concentrically forming concave portions having a plurality of circumferential groove structures on the inner surface of the top wall of the inner cap. It is a thing.

  In the invention according to the fourth aspect, since the concave portions forming the concaves and convexes are continuous circumferential groove shapes, it is easy to manufacture the mold surface for molding the inner surface of the top wall of the inner cap.

  The invention according to claim 5 is configured in the configuration of the invention according to claim 2 by forming a plurality of concave portions in the shape of a plurality of holes in the substantially entire area of the inner surface of the top wall of the inner cap, thereby forming irregularities. It is a thing added.

  In the invention according to claim 5, substantially the entire area of the inner surface of the top wall of the inner cap functions as a dew condensation function part, and each recess is independent. There is almost no flow movement of the coating liquid that has adhered due to condensation, and thus the condensed coating liquids are hardly combined to become large.

  The present invention is more effective when the contents are more easily volatile than when the contents are water. That is, examples of contents that are more volatile than water (boiling point: 100 ° C., 1 atm) include ethanol (boiling point: 78.4 ° C., 1 atm) or a mixture of water and ethanol (for example, ethanol 95% and water). A 5% “binary azeotrope” has an azeotropic point of 78.15 ° C., 7.5% of water, 18.5% of ethanol, and 74% of benzene (boiling point 64.9 ° C.). ) And the like, the contents containing alcohol are more likely to volatilize, i.e., easily condensate, and therefore are more likely to benefit from the effects of the present invention.

  Moreover, as a coating liquid accommodated, a hair dyeing liquid is mentioned, for example. As the hair dyeing solution, temporary colorants, hair nail polish and hair dye are preferable, and hair nail polish is particularly preferable.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the first aspect of the present invention, the cap body is composed of the outer cap constituting the attaching / detaching function portion and the inner cap functioning as the packing, so that the attaching / detaching operation is stronger and more stable. A strong sealing operation can be obtained, and thereby an excellent cap function is exhibited.

  In addition, since the surface area of the inner surface of the top wall of the inner cap is extremely large, the adhesion of the droplets of the condensing coating liquid does not flow and move, and the condensing coating liquid flows out by dripping or the like. Thus, it is possible to prevent the occurrence of inconvenience that soils clothes and body.

  Furthermore, the heat insulation effect of the outer cap and the inner cap weakens the thermal effect of the environmental temperature on the internal space of the cap body where the coating solution vapor is located, thereby effectively condensing the coating solution vapor. Can be suppressed.

  In the invention according to claim 2, when the coating liquid vapor in the internal space of the cap body condenses, the dew will surely condense in this recess prior to the other part of the inner cap inner surface. Condensation is hardly generated on the inner surface of the inner cap, so that it is possible to reliably prevent the occurrence of contamination due to the condensing coating liquid.

  In the invention according to claim 3, since the substantially whole area of the inner surface of the top wall of the inner cap functions as a dew condensation functional part, it is possible to hold the dew condensation coating liquid in a wide area range, thereby It can prevent effectively that it becomes a big drop shape.

  In the invention according to the fourth aspect, since it is easy to manufacture a mold for molding the inner surface of the top wall of the inner cap, the inner cap can be molded easily and inexpensively.

  In the invention according to claim 5, there is no occurrence of enlarging due to the coupling between the condensed coating liquids, and there is almost no flow movement due to this, so that the occurrence of the outflow movement of the condensed coating liquid can be effectively performed. Can be blocked.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a half front view of the entire comb-applied container with the cap body 1 according to the present invention assembled to a combination of a container body 15 and a comb body 23, and FIG. It is the whole side view.

  The container main body 15 is provided with a cylindrical neck 19 having a thread on the outer peripheral surface thereof standing upright at the upper end of a substantially elliptic cylindrical body 16 via a reduced diameter step. A long cylindrical mouth tube portion 21 is erected on the upper end of the tube portion 19 via a top plate portion 20 having an opening at the center, and is assembled on the top surface of the top plate portion 20 so as to surround the mouth tube portion 21. The cylindrical piece 22 is erected and the lower end opening of the body portion 16 is sealed with a bottom cover portion 17 having an O-ring 18. A liquid-absorbing liquid 27 impregnated with is stored. Note that the lower end opening of the body portion 16 may be opened and closed by the bottom lid portion 17 for refilling the coating liquid and the like.

  In the mouth tube portion 21 of the container body 15, a liquid-absorbing applicator 28 formed in a substantially flat plate shape projects the upper half portion upward from the mouth tube portion 21 and the lower half portion in the liquid sucking body 27. It is assembled in a form that has been depressed.

  A comb body 23 in which a plurality of comb teeth 24 are positioned outside the projected application body 28 is assembled to the mouth tube portion 21 from which the application body 28 protrudes. From the upper end of the assembled cylinder 26 that is closely fitted and assembled to the assembled cylinder piece 22, a tapered cylindrical shoulder cylinder 25 is provided standing upright and the width of the front and rear is reduced toward the upper end, and from the upper end of the shoulder cylinder 25, Except for the plate-like ones at the left and right ends, a plurality (two in the case of the illustrated embodiment) of comb teeth 24 extending in an arch shape in front and rear are erected in a posture straddling the projecting application body 28. ing.

  That is, the upper end portion of the application body 28 protruding from the shoulder tube 25 of the comb body 23 is covered with the left and right end plate-like comb teeth 24 on the upper and lower ends, but the front and rear surfaces and the upper surface thereof are applied with this application. It is exposed from between the comb teeth 24 straddling the upper end of the body 28.

  The cap body 1 according to the present invention assembled to the comb-coated applicator main body has a hard outer cap 2 that exhibits a high self-shape holding force and exhibits a stable attaching / detaching function to the container main body 15, and a high packing. It has a double wall structure composed of an inner cap 8 made of a soft elastic material that exhibits its function.

  The outer cap 2 has a top cylindrical shape composed of a top plate 3 and a barrel 4, and a lower end portion of the barrel 4 is a screwed portion 5 that is screwed into a neck tube portion 19 of the container body 15. A circumferential ridge-shaped seal portion 6 that achieves a seal with the inner cap 8 is formed on the inner circumferential surface portion of the barrel 4 positioned above the screwing portion 5. The outer cylinder piece 7 is erected continuously from the portion so as to surround the entire body cylinder 4.

  The inner cap 8 has a top cylindrical shape composed of a top wall 9 and a cylindrical wall 13, and a sealed cylindrical part that closely fits the lower end of the cylindrical wall 13 to the assembled cylindrical piece 22 of the container body 15. 14, the upper end of the outer peripheral surface of the seal cylinder portion 14 is a portion in close contact with the seal portion 6 of the outer cap 2, and the top wall 9 of the inner cap 8 has a purpose of increasing the surface area of the top wall 9. Thus, a large number of irregularities 10 are formed.

  FIG. 3 shows a first embodiment having a configuration related to the unevenness 10. The unevenness 10 has a recess 11 formed in substantially the entire inner surface of the top wall 9 of the inner cap 8 as shown in FIG. 4. The projection 11 is formed by projecting a large number of projections 12, and the projections 12 are arranged at substantially equal intervals.

  Each convex portion 12 in this first embodiment example has a relatively large height and size, and thus the uneven state formed becomes rough, and the adhesion of the condensed coating liquid to the top wall 9 is Adhesion to the corner portion, which is a connecting portion between the concave portion 11 and the convex portion 12, becomes the main force, and is achieved and maintained.

  In the first embodiment, the coating liquid vapor in the inner cap 8 is not easily condensed on portions other than the inner surface of the top wall 9 and is easily affected by the environmental temperature by providing the recess 11. Condensation is formed on the inner surface of the top wall 9, and the coating liquid condensed on the inner surface of the top wall 9 is attached and held on the inner surface of the top wall 9 in the state described above, and does not flow out of the unevenness 10.

  FIG. 5 shows a second embodiment having a configuration related to the unevenness 10, and the unevenness 10 has a plurality of thin circumferential groove-like recesses 11 on the inner surface of the top wall 9 as shown in FIG. Arranged concentrically or as shown in FIG. 7, a large number of fine recesses 11 are arranged vertically and horizontally on the inner surface of the top wall 9.

  In this second embodiment example, since the size of the concave portion 11 is small, the concave and convex state of the concave and convex portion 10 to be formed becomes fine, so that the coating liquid condensed on the concave and convex portion 10 on the inner surface of the top wall 9 is It adheres to the inner surface of the top wall 9 with a very large contact area, so that it adheres to the inner surface of the top wall 9 with a sufficiently large adhesion force and does not flow out of the unevenness 10.

  In the illustrated embodiment, the outer cylinder piece 7 provided on the outer cap 2 improves the sitting position of the application container with the comb in the inverted state when the cap body 1 is assembled to the container body 15. For one purpose, the heat insulating action of the outer cylinder piece 7 causes the influence of the environmental temperature on the inner cap 8 to act more strongly on the top wall 9 part than on the cylinder wall 11 part. Condensation of the coating liquid vapor can be concentrated on the top wall 9 portion, and a favorable design is imparted to the appearance of the entire comb-coated coating container.

Experiment 1 Explanation of the progress of dew condensation due to changes in ambient temperature.
Store in a product form with no irregularities on the top wall of the inner cap, store it at a constant temperature, leave it at room temperature for half a day after storage, equalize the temperature of each sample, open the cap body, and measure the weight of the cap body together with the condensation liquid. Next, the condensed liquid is wiped off, the weight of the cap body is measured again, and the result of calculating the amount of the condensed liquid from the difference between the numerical values before and after that is shown in the table of FIG. From this experimental result, it can be seen that condensation is promoted and the condensation liquid increases when the environmental temperature varies.

Experiment 2
The effect of making it difficult for the condensed coating liquid to flow down and drop due to the difference in shape between the example in which the top wall of the inner cap was uneven and the comparative example in which the inner cap was not provided was compared.

  A pseudo-condensation liquid having the same composition as that of the condensed coating liquid is prepared, and the pseudo-condensation liquid is dispersed and dropped on the concave portion of the top wall of the example and the top wall part of the comparative example. The amount of condensation was reproduced using the prescribed amount in the table.

  Then, from the state in which the opening of the inner cap is directed upward, it is rotated halfway so that the opening of the cap body is directed downward, and is further rotated halfway so that the opening of the cap body is directed upward. Then, it was observed whether there was any flow or dripping movement from the opening of the cap body.

  As is apparent from the observation results shown in FIG. 9, the example of the present invention exhibits a three-fold effect compared to the comparative example. The rotation speed of the cap body was set to 1 rotation in 2 seconds.
