JP6730179B2 - Cap with comb - Google Patents

Description

The present invention relates to a comb-equipped cap that can be attached to the mouth tube portion of a container body, and more particularly to a comb-equipped cap configured to apply the content of a hair nail polish or a hair dye solution stored in the container body to hair. Is.

As a comb-like cap of this kind, conventionally, for example, as shown in Patent Document 1, a cap main body that can be attached to a mouth cylinder of a container main body containing contents, and a cap main body provided on the upper surface of the cap main body It is known that a structure including a comb part is provided. The comb portion is provided with a plurality of comb teeth arranged in a line. Out of the comb teeth, a discharge port for discharging the contents of the container body is formed on a side surface of the comb teeth in a direction parallel to the comb teeth facing the adjacent comb teeth. Further, inside the comb tooth, a communication hole that communicates the above-described discharge port with the inside of the cap body is formed. In this comb cap, the contents contained in the container body are discharged from the discharge port through the communication hole, so that the contents are discharged into the gap between the comb teeth and the comb is combed to remove the hair. The contents can be applied to.

However, in the conventional cap with a comb described above, the discharge port for discharging the content is formed only on the side surface in the comb tooth parallel direction, and the content is discharged only between the adjacent comb teeth. Therefore, if the viscosity of the contents is increased, it becomes easier to hold the contents between the comb teeth, but it is not difficult to apply it to the hair, and the discharged contents are high in the tip of the comb portion with the discharge port. If it is collected only in the portion, uneven coating is likely to occur when the contents are applied to the hair while combing the contents. On the other hand, if the viscosity of the contents is low (softened), it is easy to apply to the hair, but the holding force for accumulating the contents between the comb teeth is reduced and it flows downwards and stains the surroundings. It may not be possible to eject a large amount at one time, and the coating amount of the content may be insufficient, resulting in uneven coating.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(First embodiment)
First, the first embodiment will be described with reference to FIGS.
1 is a plan view of a cap 1 with a comb according to the present embodiment, FIG. 2 is a semi-longitudinal sectional view taken along the line AA shown in FIG. 1, and FIG. 3 is a semi-longitudinal section taken along the line BB shown in FIG. FIG. 4 is a plan view, and FIG. 4 is a cross-sectional view of the sub-comb tooth piece.
In the present embodiment, the open end side (the lower side in FIG. 2) of the comb cap 1 is the lower side, and the opposite side (the upper side in FIG. 2) is the upper side. Further, a comb tooth parallel direction (horizontal direction in FIG. 1) in which comb tooth pieces 7 and sub comb tooth pieces 10 described later are arranged is defined as an X direction, and a direction orthogonal to the X direction (longitudinal direction in FIG. 1) is a Y direction. And Further, reference numeral O extending in the vertical direction in FIG. 2 is a central axis line (center axis O) of the cap 1 with a comb, and reference numeral O1 is a central axis line (comb tooth axis O1) of a comb tooth piece 7 described later. Is.

The comb-like cap 1 is a member integrally attached by injection molding made of synthetic resin such as polyethylene or polypropylene, which is attached to the mouth tube portion of the container body (not shown). The container body (not shown) is a squeeze bottle in which contents such as a hair nail polish and a hair dye are stored, and its body has squeeze-deformable and recoverable flexibility.

The comb cap 1 has a cylindrical assembly tube 2 that is externally screwed to the mouth tube portion of a container body (not shown), and the top wall of the assembly tube 2 is continuously connected to the upper end of the assembly tube 2 in the shape of an inner collar. On the lower surface of 3, a short cylindrical seal cylinder piece 4 that fits tightly in the opening of the mouth cylinder is hung. On the outer peripheral surface of the assembling cylinder 2, a plurality of ridge portions 2a extending in the vertical direction are arranged at intervals in the circumferential direction. Then, a substantially elliptical top plate 6 whose upper end extends in the X direction in a plan view shown in FIG. 1 is formed on the upper end of the assembling cylinder 2 through the top wall 3, and the standing cylinder 5 stands upright toward the top plate 6. It is set up. In the upper part of the standing cylinder 5, inclined surfaces 5a are formed in the Y direction, the diameter of which gradually decreases as it goes upward.

On the upper surface of the top plate 6, a plurality of comb tooth pieces 7 are erected in a state of being aligned left and right. The comb tooth piece 7 is a flat plate-shaped member parallel to the central axis O, and has a pointed shape whose width is gradually reduced as it goes upward as shown in FIG. Each of the tip end portion and the side end portion of the comb tooth piece 7 has a circular arc shape in cross section. As shown in FIG. 1, the plurality of comb tooth pieces 7 are arranged in parallel with each other along the Y direction when viewed from the tip side (upper side) of the comb tooth pieces 7, and at a constant interval in the X direction. Are arranged in a line in a straight line.

Of the plurality of comb tooth pieces 7, the side surfaces of the tip portions of the comb tooth pieces 7A to 7C located at the center of the top plate 6 are provided with pin members extending in the X direction and penetrating the plurality of comb tooth pieces 7. The formed through hole 8 is provided. A communication hole 9 is formed in the central axis O direction from the through hole 8 to communicate with the inside of the standing cylinder 5 through the top plate 6. That is, a round hole-shaped through hole 8 penetrating in the X direction is formed in the center portion of the tip end portion of the comb tooth piece 7 in the Y direction, and the center portion of the through hole 8 in the axial direction (X direction). The upper end of the communication hole 9 is communicated with each other, and both ends of the through hole 8 serve as the first discharge port 81 of the discharge port 80 for discharging the content into the space S between the adjacent comb tooth pieces 7. That is, the first ejection ports 81 are formed on both side surfaces of the comb tooth pieces 7A to 7C in the X direction, and are formed symmetrically with the comb tooth axis O1 interposed therebetween.

The two comb tooth pieces 7D to 7E at both ends of the comb tooth piece 7 have a function of protecting the comb tooth pieces 7A to 7C, and the through hole 8 is formed like the comb tooth piece 7. However, since the communication hole 9 is not formed, the contents are not discharged. Here, the reason why the through holes 8 are also formed in the comb tooth pieces 7C and 7D is that the pin member of the core mold is laterally inserted in the mold during injection molding.

Subcomb teeth 10 are arranged at both ends of the space S between adjacent comb teeth 7 in the Y direction, and stand up to the height of the central portion of the ejection port 80 (through hole 8). The sub comb tooth piece 10 has a rounded triangular shape in cross section, and the content discharged from the first discharge port 81 is located between the comb tooth pieces 7 on the inner side which is the discharge port 80 (through hole 8) side. A recessed liquid reservoir 11 is provided so that the space S can be more easily held.

Next, the operation of the cap with a comb thus configured will be described.
First, the container body in which the cap with comb 1 is assembled to the mouth cylinder is pressed with a finger or the like to be squeezed. As a result, the internal pressure of the container body rises, and the contents in the container body are discharged from the top plate 6 through the communication hole 9 and the first discharge port 81.
The content discharged from the first discharge port 81 collects in the space S between the adjacent comb tooth pieces 7, and the sub comb tooth piece 10 having the liquid reservoir 11 is provided in this space S. Even if the viscosity of the material is low (soft), the holding force for accumulating the content is exhibited by the liquid reservoir 11, and even if a large amount of the content is discharged at one time, it can be prevented from dripping to the outside, and more content can be obtained. Since an object can be applied to hair, uneven application can be prevented. Further, even if the viscosity of the contents is lowered, the presence of the sub-comb tooth piece 10 makes it possible to obtain a combing feeling with an appropriate resistance when combing hair or the like.

(Second embodiment)
5 to 8 show a second embodiment of the comb cap. 5 to 7, the configuration of the comb tooth piece 7 is mainly different, but for the configuration similar to that of the above-described first embodiment, the same reference numerals are given to the members corresponding to the above-described members. The description is omitted.

In the second embodiment, as shown in FIG. 8, each comb tooth piece 7 is provided with a side end recessed portion 12 which is recessed except in the vicinity of the tip end portion at the side end portion extending in the Y direction. At the start of combing the hair, the contents accumulated in the space S between the comb tooth pieces 7 are often excessively applied to the hair or the like. It can flow into the concave portion 12 to be temporarily accumulated, and when the hair is continuously combed, the contents accumulated in the side end concave portion 12 can be applied to the hair or the like, so that uneven coating can be prevented.

(Third Embodiment)
9 to 11 show a third embodiment of the comb cap. 9 to 1, the same components as those of the above-described first embodiment are denoted by the same reference numerals and the description thereof will be omitted.

In the third embodiment, a first ejection port 81 and a second ejection port 82, which are different in position in the direction of the comb tooth axis O1, are formed as ejection ports 80 for ejecting the contents. The second discharge port 82 is opened at a substantially intermediate height of the comb tooth pieces 7A to 7C. The second discharge port 82 is formed by contacting a core die (not shown) for forming the communication hole 9 with a vertical cutting pin (not shown) that is a part of the cavity die, It is a vertical biting hole formed in the contact portion. By bringing the contact surface of the vertical cutting pin and the contact surface of the cavity mold into contact with each other, the synthetic resin is prevented from rotating around these contact portions during molding, and the second discharge port 82 is formed.

The opening area of the first ejection port 81 is preferably larger than the opening area of the second ejection port 82. The opening area of the first ejection port 81 is made larger than the opening area of the second ejection port 82 when the contents are ejected from the ejection port 80, the first ejection port 81 on the tip side of the comb tooth piece 7 is Since the distribution path of the contents becomes long, the first ejection port 81 on the tip side of the comb tooth piece 7 is less likely to eject the contents than the second ejection port 82 on the base end side of the comb tooth piece 7. Therefore, if the opening areas of the first ejection port 81 and the second ejection port 82 are the same, the ejection amount from the first ejection port 81 on the tip side of the comb tooth piece 7 is the ejection amount of the second ejection port 82. Less than. On the other hand, in the cap 1 with a comb having the above-described configuration, since the opening area of the first ejection port 81 is large, variations in the ejection amount at the first ejection port 81 and the second ejection port 82 are suppressed, The discharge amount can be equalized.

The communication hole 9 has a pore portion 9b having the same diameter as that of the first embodiment so that a sufficient discharge amount can be ensured even if the discharge port 80 is the first discharge port 81 and the second discharge port 82. It is composed of a large hole portion 9a having a diameter larger than that of the small hole portion 9b. The fine hole portion 9b extends on the comb tooth axis O1, and the upper end of the fine hole portion 9b communicates with the central portion of the first discharge port 81 in the axial direction. The thick hole portion 9a is arranged below the fine hole portion 9b, and the lower end of the thick hole portion 9a communicates with the inside of the standing tube 5. The thick hole portion 9a is widened outward in the X direction with respect to the fine hole portion 9b. The bases of the comb teeth 7A to 7C are formed with a bulging portion 7a bulging by an amount corresponding to the widening of the large hole portion 9a in the X direction.

According to the cap 1 with a comb having such a configuration, the contents are discharged from the first discharge port 81 and the second discharge port 82 which are located at different positions in the direction of the comb tooth axis O1, respectively, and the contents are spread over a wide area of the space S. Since the substance is ejected, a large amount of the substance can be ejected at one time, and uneven coating of the substance can be prevented. Further, since the first ejection port 81 and the second ejection port 82 are formed on the side surface of one comb tooth piece 7, respectively, the ejection amount of the contents is increased, so that a sufficient amount of the contents can be applied to the hair. It can be applied.

The opening area of the first ejection port 81 is larger than the opening area of the second ejection port 82, and the contents are easily ejected from the first ejection port 81. Therefore, the first ejection port 81 and the second ejection port 81 are discharged. Dispersion of the discharge amount at the outlets 82 is suppressed, and the discharge amounts from the discharge ports 81 and 82 can be equalized. As a result, the contents can be evenly discharged into the space S between the comb teeth pieces 7, and the contents can be evenly applied to the hair or the like.

(Fourth Embodiment)
12 to 14 show a fourth embodiment of the cap with a comb. 12 to 14, the same components as those of the above-described second and third embodiments are denoted by the same reference numerals and the description thereof will be omitted.

The fourth embodiment is a combination of the side end recesses 12 of the comb tooth piece 7 of the second embodiment and the configuration of providing the second ejection port 82 of the third embodiment.
According to the cap 1 with a comb having such a configuration, the discharge amounts from the discharge ports 81 and 82 can be equalized, so that the contents are uniformly discharged into the space S between the comb tooth pieces 7. In addition, the contents can flow into the side end recesses 12 of the comb tooth piece 7 to be temporarily stored therein, and can be collected in the side end recesses 12 when the hair is continuously combed. Since the content can be applied to the hair or the like, the content can be applied to the hair or the like evenly.

Although the configuration of the present invention and the function and effect thereof have been described with reference to the examples, the embodiments of the present invention are not limited to the above-described embodiments.
For example, the comb-equipped cap 1 of the above-described embodiment has a plurality of comb tooth pieces 7 arranged in a row and erected, but a plurality of rows or a staggered arrangement may be adopted. Further, although the flat plate-shaped comb tooth piece 7 is provided in the above-described embodiment, the present invention can appropriately change the shape of the comb tooth piece. For example, a round bar-shaped comb tooth piece is provided. It doesn't matter. Further, in the above-described embodiment, the sub-comb tooth piece 10 has a rounded triangular shape in cross section, but may be appropriately changed as long as it has a liquid reservoir 11 on the inner side that is the through hole 8 side. It is possible.

The contact surface of the core die or the vertical cutting pin provided with the second ejection port 82 may be a plane orthogonal to the central axis of the vertical cutting pin or the core die, or an inclined surface. .. Furthermore, in the above-described embodiment, the comb cap 1 is configured to be externally screwed to the mouth tube portion of the container body. However, in the present invention, the comb cap 1 is attached to the mouth of the container body by a method other than screwing. It may be attached to the tubular portion, for example, the cap with comb 1 may be attached to the mouth tubular portion by undercut fitting.

As described above, the cap with a comb of the present invention can sufficiently exert the holding force for accumulating the content in the space between the comb teeth pieces even when the viscosity of the content is reduced, and thus the application to the hair can be performed. In order to prevent uneven coating when applied, it is expected that it will be used in a wide range of products such as gray hair dye and hair nail polish.
