Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a cap with a comb configured to directly apply a content liquid such as a hair dyeing solution or a hair manicure stored in a container body to the hair from the container body.
[0002]
[Prior art]
As a cap with a comb, which is assembled as a cap on a container body having squeeze properties, and can be applied directly to the hair, such as white hair dyeing liquid and hair nail polish, on the upper end of the conventional container body A configuration in which each comb tooth piece is erected in the vertical direction is proposed in contrast to a structure in which each comb tooth piece of the comb function portion located is protruded in the horizontal direction.
[0003]
The above-mentioned conventional cap with a comb has a structure in which the comb function portion formed by the comb teeth body is located immediately above the container body in a posture in which each comb tooth piece is erected. However, it can be easily achieved that the comb function part is appropriately opposed to the target hair part by the touch feeling of the hand holding the container body, so that the content liquid can be satisfactorily applied to the target hair part. The extraction channel, which is a supply channel for the content liquid to each comb tooth piece constituting the comb function part, can be easily achieved, and is arranged along the direction perpendicular to the direction in which the content liquid is extracted from the container body. Therefore, it is possible to distribute the liquid content with equal dispensing pressure to each of the dispensing channels by simply forming a “reservoir” portion in front of each dispensing channel. Make the amount of the content liquid to be even, Can be obtained coating with no fabric unevenness good content liquid has advantages such.
[0004]
By the way, this conventional comb cap has a standing upright cylinder standing up and down at the upper end of an assembled cylinder that is tightly assembled to the mouth cylinder portion of the squeeze container through an inner flange-shaped top wall. A plurality of assembly holes penetrating up and down in series in the left-right direction and at equal intervals were opened in the top plate that was connected continuously and closed the upper end of this upright cylinder, and frame comb teeth pieces were erected from both the left and right ends of the top plate On the lower surface of the cap main body and the base plate placed on the top plate of the cap main body, there are suspended fitting cylinder pieces which are individually tightly fitted into the assembly holes of the cap main body. Comb pieces are erected on the upper surface of the base plate immediately above the piece, and in each combination portion of the comb teeth piece and the fitting cylinder piece, from the upper end portion of the comb tooth piece to the lower end surface of the fitting cylinder piece, A comb tooth body having a pour-out path with a spout opening opened on the left and right side surfaces of the upper end of the comb tooth piece. And it is configured to be assembled.
[0005]
The reason for the two-body structure is to prevent the content liquid poured out from the spout of each comb tooth piece from splashing to the side (left-right direction) of the comb function part during use. In addition, the frame comb teeth pieces on both the left and right ends have a structure having no holes. Thus, the comb teeth pieces having holes (spout ports) and the frame comb teeth pieces without holes located on both sides thereof are Since it is difficult to integrally mold with a molding pin for molding, a comb tooth body with a comb tooth piece and a cap body with a frame comb tooth piece are separately molded and assembled together. It is attached.
[0006]
[Problems to be solved by the invention]
However, in the above-described prior art, if a gap is formed between the combined cap body and the comb body, the content liquid may enter the gap and cleaning may be troublesome. There was a problem.
[0007]
Further, when the boundary portion (boundary line) between the cap body and the comb tooth body is visible, there is a problem that the appearance may be deteriorated.
[0008]
And the above-mentioned pouring path for improving the pouring fluidity for the configuration in which the comb tooth body is assembled to the cap body by inserting the fitting cylinder piece whose inside forms a part of the pouring path into the assembling hole There is a problem that the expansion of the cross-sectional area is restricted, so that it is constrained to widen the pouring path and increase the pouring fluidity.
[0009]
Furthermore, since the cap body and the comb teeth are required to be molded separately, and the cap body and the comb teeth are required to be assembled independently, the manufacturing cost is increased. there were.
[0010]
Therefore, the present invention was devised to solve the above-described problems in the prior art, and integrally formed with a comb cap having comb teeth having spouts and frame comb teeth on both sides thereof. Therefore, it is an object of the present invention to obtain a good feeling of use and high fluidity of pouring, improve hygiene and appearance, and reduce manufacturing costs.
[0011]
[Means for Solving the Problems]
