Description

  The present invention relates to a liquid container cap that is attached to a container that stores a liquid to be applied to the head.

There are shampoos, treatments and the like as liquid agents to be applied to the head. In particular, in the case of shampoos that wash away oil clogged in the scalp pores, it is desirable to apply them directly to the scalp as much as possible without adhering to the hair. However, a shampoo container equipped with a nozzle having a liquid agent discharge hole at the tip end needs to be separated from the scalp because the liquid agent discharge hole is blocked by the scalp when the nozzle is brought into direct contact with the scalp. It was hard to reach the scalp. Therefore, a cap that can discharge the liquid toward the head even when the tip of the nozzle is brought into direct contact with the scalp has been proposed (for example, see Patent Document 1).
The cap of Patent Document 1 discharges a liquid agent from the tip of a columnar body standing on the top of the cap, and the tip of a short columnar body is blocked by the scalp by contacting the long columnar body with the scalp. The liquid can be discharged and applied to the head.

JP-A-9-313241

  However, since the tip of the long columnar body that is in direct contact with the scalp in the cap of Patent Document 1 is blocked by the scalp, it was not possible to apply the solution to the scalp from there. In addition, in the columnar body, it is difficult to scrape a certain range of hair, press the hair against the scalp, and expose the scalp, so that it is difficult to directly apply the liquid agent discharged from the short columnar tip to the scalp. Moreover, the cap of patent document 1 does not solve the new subject of controlling the spreading direction of the liquid agent on the scalp and realizing the spread of the liquid agent as a feeling of use.

  The problem of the present invention is for a solution container that can solve the above-described problems of the prior art, and that can control the spreading direction of the solution on the scalp and solve the new problem of realizing the spread of the solution as a feeling of use. To provide a cap.

  The present invention is a liquid container cap to be attached to a container for storing a liquid agent to be applied to the head, and has a base portion and a tip portion, and the tip portion is provided with a liquid agent discharge hole, Three or more convex portions are provided radially around the liquid agent discharge hole, and the convex portion rises from the liquid agent discharge hole side of the tip portion and rises from the outer side in the cap radial direction from the one end portion. The other end portion, and the uppermost end of the convex portion is located above the liquid agent discharge hole, and the convex portion is formed with an interval in the circumferential direction of the cap. The gap between them provides a cap for a liquid agent container in which the liquid agent discharged from the liquid agent discharge hole serves as a flow path for the liquid agent flowing out toward the outside in the cap radial direction.

  Moreover, this invention provides the container containing a liquid agent with which the said cap for liquid agent containers is attached to the container in which the liquid agent apply | coated to a head was accommodated.

  According to the liquid container cap and the liquid container of the present invention, the liquid agent can be applied directly to the scalp while the tip of the cap is brought into stable contact with the head, and the direction in which the applied liquid spreads is controlled. And the spread of the liquid agent can be easily realized as a feeling of use.

Below, this invention is demonstrated based on the preferable embodiment.
The liquid agent container cap 1 of the first embodiment (hereinafter also simply referred to as a cap 1) is a liquid agent container cap attached to a container that contains a liquid agent to be applied to the head. The cap 1 is attached to a container as shown in FIG. 2, for example, and is used to apply a liquid agent (not shown) contained therein to the head 6. The container 9 shown in FIG. 2 is formed in a shape and size that can be easily gripped with one hand, and can be gripped with one hand to perform an operation of applying the liquid agent to the head 6. A container 9 shown in FIG. 2 is a synthetic resin container having a trunk portion 91, a bottom portion 92, a shoulder portion 93, and a mouth portion 94 having an opening at the upper end.

  As shown in FIG. 1, the cap 1 of this embodiment has a base portion 2 and a tip portion 3, and a liquid agent discharge hole 31 is provided in the tip portion 3. Further, the cap 1 is provided with three or more plate-like ribs 4 (convex portions) radially with the liquid agent discharge hole 31 as the center. Each of the plate-like ribs 4 has one end portion 41 rising from the liquid agent discharge hole 31 side of the distal end portion 3 and the other end portion 42 rising from the outer side in the cap radial direction from the one end portion 41. Further, the uppermost end 43 of the plate-like rib 4 is positioned above the liquid agent discharge hole 31. Further, the plate-like ribs 4 are formed at intervals in the circumferential direction A of the cap, and a gap 46 between the plate-like ribs 4 is formed so that the liquid agent discharged from the liquid agent discharge hole 31 faces outward in the cap radial direction. It becomes the flow path of the liquid agent which flows out.

  In the present specification, “upper” and “upper” mean the upper direction (the direction in which the cap 1 is located with respect to the bottom 92) in FIG.

The cap 1 of this embodiment is formed integrally with a base portion 2 having a cylindrical outer shape and a tip portion 3 positioned on the upper side. The distal end portion 3 includes a truncated cone portion 35 whose outer shape is a truncated cone shape, and a top surface portion 34 provided with a liquid agent discharge hole 31 at the center on the upper surface portion of the truncated cone portion 35.
By providing the truncated cone part 35 on the lower side of the top surface part 34, the liquid agent does not stay on the top surface part 34 or in the gap between the plate-like ribs 4 even after use of the container, and follows the inclined surface of the truncated cone part 35. Therefore, it is hygienic because the liquid flows down.

Further, in the present embodiment, as shown in FIG. 1C, a plurality of plate-like ribs 4 are spaced apart from the circular top surface portion 34 in plan view, with the liquid agent discharge hole 31 as the center. It is provided radially outward in the cap radial direction.
Each of the plate-like ribs 4 has one end portion 41 rising from the liquid agent discharge hole 31 side of the top surface portion 34 and the other end portion 42 rising from the outside of the one end portion 41 in the cap radial direction. Further, each of the plate-like ribs 4 extends in the radial direction of the cap in the plan view of the cap 1.

From the viewpoint of increasing the amount of the liquid agent stored in the top surface portion 34, the plate-like rib 4 (convex portion) is preferably provided from the outer edge 32 of the top surface portion 34 toward the radially outer side of the cap. However, as shown in FIG. 1C, the outer peripheral portion 33 of the liquid agent discharge hole 31 (between the edge of the liquid agent discharge hole 31 and the outer edge 32 of the top surface portion 34) in the top surface portion 34 is directed radially outward of the cap. It may be provided. The rising position of the one end 41 of the plate-like rib 4 can be appropriately determined depending on the viscosity of the liquid agent and the discharge amount of the liquid agent.
The diameter of the top surface portion 34 can be appropriately determined depending on the viscosity of the liquid agent and the discharge amount of the liquid agent, but in this embodiment, it is preferably 3 mm or more, more preferably 5 mm or more, and preferably 15 mm or less, More preferably, it is 10 mm or less.

  Here, the outer edge 32 of the top surface portion 34 refers to a ridge line portion at the boundary between the top surface portion 34 and the truncated cone portion 35 when the top surface portion 34 is a flat surface, and when the top surface portion 34 is a curved surface, the top surface portion 34. And the part where the curvature radius of the boundary of the truncated cone part 35 changes is indicated. In addition, when the top surface part 34 is a curved surface, the said diameter points out planar view diameter.

  Further, the rising position of the one end portion 41 of the plate-like rib 4 is preferably 0 mm or more and 10 mm or less, more preferably 2 mm or more and 4 mm or less from the edge of the liquid agent discharge hole 31 when the diameter of the base portion 2 is 28 mm.

  From the viewpoint that the plate-like rib 4 (convex portion) is brought into contact with the head 6 stably and from the viewpoint that the liquid agent can be spread over a predetermined region of the scalp 61 while obtaining a feeling that the liquid agent has spread over the scalp 61. 3 or more are required. In addition, the number is preferably 8 or less from the viewpoint of easily allowing the liquid agent to diffuse into the scalp 61 and preventing dirt (a mixture of the liquid agent and sebum dirt) from collecting on the top surface of the cap. In the present embodiment, there are six plate-like ribs 4. The number of plate-like ribs 4 (convex portions) is preferably 3 or more, more preferably 5 or more, and preferably 8 or less. 4-6 is an example in case the number of the plate-like ribs 4 is 3, 4, and 8 in order.

  In the method of applying the liquid agent to be applied to the head 6 using the cap 1 of the present embodiment, for example, the container 9 containing the liquid agent is grasped by hand, and the plate-like shape of the cap 1 attached to the container 9 is used. As shown in FIG. 3A, the top end 43 of the rib 4 (convex portion) is brought into contact with the head 6 and pressed, and in this state, the body 91 of the container 9 is pressurized by hand. And a liquid agent (not shown) is discharged toward the head 6.

According to the cap 1 of the present embodiment, three or more plate-like ribs 4 (convex portions) are formed at intervals in the circumferential direction A of the cap. It can be contacted. Further, since the uppermost end 43 of the plate-like rib 4 (convex portion) is positioned above the liquid agent discharge hole 31, the liquid agent discharge hole 31 is not blocked by the scalp 61. Furthermore, the scalp 61 can be easily exposed by scraping a certain range of hair or pressing the hair against the scalp 61 by the plate-like rib 4 (convex part). Therefore, the liquid agent can be applied directly and efficiently to the scalp 61.
In addition, as shown in FIG. 3C, the liquid agent 7 discharged from the liquid agent discharge hole 31 flows out toward the outside in the cap radial direction using the gap 46 between the plate-like ribs 4 as a flow path for the liquid agent 7. In this way, the plate-like rib 4 can control the direction in which the applied solution 7 spreads, and the solution 7 can be efficiently spread on the scalp 61, so that the user of the cap 1 and the container can spread the solution. It becomes easy to feel as a feeling of use.
As in the cap 1 of this embodiment, it is preferable that the convex portion is a plate-like rib 4 because the direction in which the liquid agent spreads can be easily controlled. Further, the cap 1 can be easily molded.

Further, it is desirable that the intervals between the plate-like ribs 4 be equal from the viewpoint that the liquid agent can be uniformly distributed to a predetermined region of the scalp 61 while obtaining a feeling that the liquid agent has spread to the scalp 61. .
Further, from the viewpoint of allowing the cap 1 to contact the head 6 stably, it is desirable that the heights of the uppermost ends 43 of the plate-like ribs 4 are all the same.

In the present embodiment, the height t (see FIG. 3B) from the top surface portion 34 to the uppermost end 43 of the plate-like rib 4 is 3 mm. The height t is preferably 1 mm or more, more preferably 2 mm or more, and preferably 10 mm or less, more preferably 5 mm or less.
In the case of a liquid agent such as a shampoo having a liquid agent viscosity of about 20 to 1000 mPa · S (30 ° C.), the liquid agent can easily reach the scalp 61, and from the viewpoint of smoothing the flow to the liquid agent channel, the plate from the top surface 34 The height t (see FIG. 3B) to the uppermost end 43 of the rib 4 is preferably 2 to 5 mm.
Said liquid agent viscosity is a measured value by BM type | mold viscosity meter (rotor No. 2, rotation speed 60rpm, rotation time 60 seconds).

Moreover, as shown in FIG.3 (b), the rising part 44 (after-mentioned) of the one end side of the plate-shaped rib 4 from the outer peripheral part 33 of the liquid agent discharge hole 31 has a curved surface shape, It is preferable from the viewpoint that it can be gently contacted and the liquid agent is less likely to stay in the top surface portion 34. The rising portion 44 is a portion from one end portion 41 of the plate-like rib 4 (convex portion) rising from the top surface portion 34 to the uppermost end 43 of the plate-like rib 4. The plate-like rib 4 (convex portion) has an upper edge portion, a lower edge portion coupled to the tip portion 3, and two substantially parallel side surfaces located between the upper edge portion and the lower edge portion. However, the rising portion 44 may have a curved shape when viewed from the cross-sectional view direction (see FIG. 3B).
The curvature radius R of the curved surface shape of the uppermost end 43 of the plate-like rib 4 is preferably 1.5 mm or more because it can gently contact the head. The maximum value of the preferable range of the radius of curvature depends on the diameter of the cap, but in the case of a cap having a diameter of 30 mm, it is R5 mm. In the present embodiment, the radius of curvature is R2.6 mm with respect to the cap diameter φ28 mm.

  Moreover, it is preferable that the position of the liquid agent discharge hole 31 is the center of the top surface portion 34 from the viewpoint of spreading the liquid agent uniformly around the periphery.

  Examples of the “liquid agent applied to the head” in the present invention include shampoos, treatments, rinses, tonics, hair styling gels, hair dyes and the like. The container with a liquid agent of the present invention is formed by attaching the cap for a liquid agent container of the present invention to a liquid container having an arbitrary configuration in which a liquid agent to be applied to the head is accommodated.

The present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, as shown in FIG. 3, the cap 1 of the above-described embodiment includes a discharge hole opening / closing mechanism that opens and closes the liquid agent discharge hole 31 by inserting and removing the plug member 53 from the inside of the cap to the liquid agent discharge hole 31. However, the cap for the liquid agent container and the container containing the liquid agent of the present invention may be provided with a discharge hole opening / closing mechanism for opening and closing the liquid agent discharge hole by inserting and removing the plug member from the outside of the cap. Alternatively, the liquid agent discharge hole may be closed by pressing a plug member from the inside or the outside of the cap. Furthermore, the cap for a liquid agent container or the container containing the liquid agent of the present invention may not have a discharge hole opening / closing mechanism for opening and closing the liquid agent discharge hole itself, and covers the upper end of the cap including the convex portion. Etc. may be used.

The base portion or the like may be directly fixed to the container without using such a connecting member. 3 includes a fixing portion 51 that is screwed and fixed to the neck portion 94 of the container 9, and a connection cylinder portion 52 that is screwed to the inner peripheral surface of the base portion 2 of the cap 1. The liquid agent discharge hole 31 can be opened and closed by having the plug member 53 supported by the support portion 54 and rotating the cap 1 in the circumferential direction.

Moreover, the liquid agent discharge hole 31 may be formed in the form illustrated in FIG. 7, and the hole position, number, and opening diameter can be appropriately determined according to physical properties such as the viscosity of the liquid agent. For example, instead of the four liquid agent discharge holes in FIG. 7, two liquid agent discharge holes may be arranged side by side.
In addition to ribs such as elliptical columnar ribs and square ribs, as convex portions, convex portions of various shapes such as a fan-shaped convex portion 4A (see FIG. 8) in plan view can be used. Can be used. In the case of FIG. 8, the liquid agent flow path formed by the gap 46 between the convex portions 4A has a groove shape.

  Further, the container in the present invention is not limited to a self-supporting bottle-shaped container as shown in FIG. 2, and may be a container of any other shape. In addition, each of the cap for the liquid agent container and the container to which it is attached is preferably made of a synthetic resin such as polyolefin resin, but may be made of other materials. In addition, the container may be capable of discharging the liquid agent inside by a method other than manually pressurizing the body of the container.

  Further, the inclined surface of the truncated cone part 35 does not necessarily have to be a straight line when viewed from the side, and may be a curved line convex upward or convex downward.

  Further, the tip portion 3 does not necessarily require the top surface portion 34 and the truncated cone portion 35, and the entire tip portion 3 may be hemispherical (dome-shaped). In such a case, the liquid agent discharge hole 31 is preferably provided at the apex of the tip 3.
