DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap with a comb configured to directly apply a content solution such as a gray hair dye solution or a hair manicure contained in a container body to hair from the container body.

[0002]

2. Description of the Related Art As a cap with a comb, which is assembled as a cap to a container having a squeezing property, and a content liquid such as a gray hair dyeing solution or a hair manicure of the container can be directly applied to the hair, In contrast to the configuration in which the comb teeth of the comb functioning portion located at the upper end of the container body protrude in the horizontal direction, a configuration in which the comb teeth are erected in the vertical direction has been proposed. See JP-A-10-137029).

The cap with a comb disclosed in the publication has a configuration in which a comb functioning portion formed by a comb-tooth body is located immediately above a container body in a posture in which each comb-tooth piece is erected. Even so, the comb function portion can be easily and appropriately opposed to the target hair portion by the tactile sensation of the hand holding the container body, and therefore, the content liquid can be applied to the target hair portion. This can be achieved favorably and easily, and the pouring path, which is a supply path of the content liquid to each comb tooth piece constituting the comb functioning portion, extends in a direction perpendicular to the direction in which the content liquid is led out from the container body. In this state, the liquids can be distributed to each pouring path at an equal pouring pressure by simply forming a "pool" portion in front of each pouring path. Equalize the amount of liquid poured out between This has the advantage that it is possible to obtain a good application of the content liquid without application unevenness.

[0004] The cap with a comb disclosed in the above publication has a flat standing upright back and forth through an inner flange-shaped top wall at the upper end of a mounting cylinder that is closely assembled to the mouthpiece of a squeezable container. On the top plate that covers the upper end of this upright cylinder, a plurality of mounting holes that penetrate vertically and at equal intervals are opened in the top plate, and frame comb teeth pieces are further cut from both left and right ends of the top plate. An upright cap body and a fitting tube piece which is firmly and individually tightly fitted into each of the mounting holes of the cap body are vertically provided on the lower surface of the base plate placed on the top plate of the cap body. A comb-tooth piece is erected on the upper surface of the base plate immediately above the fitting-tooth piece, and in each combination portion of the comb-tooth piece and the fitting-tooth piece, from the upper end of the comb-tooth piece to the bottom of the fitting-tooth piece. Over the end face, a comb-tooth body having a spouting path with an opening at the spout opening at the upper left and right side surfaces of the comb teeth piece, It is constructed by assembling the two-body.

[0005] The reason why the two-piece structure is adopted is that the content liquid discharged from the spout of each comb tooth leaks to the side (left and right direction) of the comb function part during use. To prevent this, the comb teeth at the left and right ends have a structure without holes.
Since it is difficult to integrally mold the frame comb tooth pieces without holes located on both sides thereof with a forming pin for forming holes,
The comb body provided with the comb teeth and the cap body provided with the frame combs are separately formed and integrally assembled.

[0006]

However, according to the prior art described in the above-mentioned publication, the hair enters into a small gap between the cap body and the comb-teeth body which are integrally assembled, There is a possibility that the content liquid may accumulate, and therefore, there is a problem that the flowability of the content liquid is deteriorated, and that the washing becomes troublesome.

[0007] Further, there is a problem that the boundary portion (boundary line) between the cap body and the comb tooth body is seen, so that the appearance is poor.

[0008] Since the comb-teeth body is mounted on the cap body by fitting a fitting cylinder piece having a part of the pouring path into the mounting hole, the pouring flow is improved in order to enhance the pourability. If the cross-sectional area of the outlet is increased, there is a risk that liquid leakage may occur due to the problem of sealing properties of the assembled portion, and therefore, there is a problem that it is not possible to widen the outlet and increase the flowability of the outlet.

[0009] In addition to the need for a mold for forming each of the cap body and the comb-tooth body, a process of assembling the cap body and the comb-tooth body is also required, which causes a problem that the manufacturing cost increases. Was.

Accordingly, the present invention has been made to solve the problems in the prior art described in the above-mentioned publication, and a cap with a comb provided with a comb tooth piece having a spout and frame comb teeth pieces on both sides thereof. The technical task is to simplify the structure of
Accordingly, it is an object of the present invention to improve the flowability of pouring, improve hygiene and appearance, and reduce manufacturing costs.

[0011]

Means for solving the above-mentioned technical problem is to provide an inner flange-shaped top wall at the upper end of an assembled cylinder that is tightly assembled to the mouthpiece of a squeezable container. And a plurality of comb teeth pieces are erected in series in the left-right direction at equal intervals near the center of the upper surface of the top plate connected to the upper end of the upright cylinder. At the same time, frame comb teeth are erected at both end portions of the top plate, and each comb tooth is provided with a pouring hole which opens in the left-right direction at the upper end thereof, and the pouring hole is formed. From the lower surface of the top plate to a through hole, at least one side of the frame comb tooth, at a position corresponding to the pouring hole, through a pin hole that opens in the left and right direction, synthetic resin material Molding in one piece.

The cap with a comb is integrally formed as a whole, and no seams or gaps are formed. Therefore, the appearance is improved, and the hair may be caught in the gaps and the content liquid may be accumulated. Therefore, the flowability of the content liquid is increased, and the washing can be easily performed.

Since the cap with a comb has an integral structure, even if the discharge path of the comb teeth is widened, the flow of the liquid can be easily increased without fear of liquid leakage at the assembled portion unlike the conventional structure. be able to.

Since the comb cap has an integral structure, a single molding die is required, and a step of assembling the components is not required, so that the manufacturing cost is greatly reduced.

Since the pin hole 12 is formed by using a molding pin that moves in the left-right direction in order to form the pouring hole 9 of the comb tooth piece 8 when the cap with comb 1 is integrally formed, the comb tooth is used. The spout hole 9 is also provided in the frame comb tooth piece 11 located on the side of the piece 8.
Thus, the same pin hole 12 is formed.

In the first embodiment, the pin holes 12 are formed in the frame comb teeth 11 on both sides. However, as in the second embodiment shown in FIG. 3, only the frame comb teeth 11 on one side are formed. , A pin hole 12 may be formed.

When the cap 1 with a comb of the present invention was actually used, even if the pin hole 12 was provided in the frame comb tooth piece 11, the liquid to be poured out had a bad influence on the application to the hair. It was found that no side leakage occurred.

FIG. 4 is a cross-sectional view showing a case where the cross-sectional area of the pouring path 10 in the comb tooth piece 8 is increased in order to increase the flowability of the liquid content.

In the above-described conventional cap with a comb having a two-body structure, the spouting path 10 having a circular cross section with a diameter of 1 to 2 mm was formed as shown by a two-dot chain line due to the problem of the sealing property of the assembling portion. Because the cap with a comb of the present invention has an integral structure,
As shown by the solid line, there is no danger of liquid leakage or the like even if the pouring path 10 having an oval cross section that is enlarged to the thickness limit at which the strength of the comb teeth 8 is maintained.

[0025]

Since the present invention has the above-described structure, the following effects can be obtained. The cap with a comb is integrally molded as a whole, and no seams or gaps are formed, so the appearance is improved, and there is no hair caught in the gaps, etc. ,
The flowability of the liquid content is increased, and the application to the hair can be smoothly and satisfactorily achieved, and the washing can be easily achieved.

Further, since the cap with a comb has an integral structure, the flow path of the comb teeth is widened, so that there is no danger of liquid leakage or the like in the assembled portion unlike the conventional structure, and the flowability of the liquid is easily reduced. Can be increased.

Since the cap with a comb has an integral structure, a single molding die is required, and a step of assembling the constituent members is not required, so that the manufacturing cost is greatly reduced.
