Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a cap of a container for containing a hair wash such as shampoo and liquid cosmetics, in particular, so that the content outlet can be opened and closed by a snap action. It relates to the cap of the container.

“Prior Art” Conventionally, a cap having a structure shown in FIG. 7 has been widely known as a cap capable of opening and closing a content outlet by a snap action.

This is a cap body 1 having a contents outlet 1a and a lid body 3 integrally formed through a reversible snap hinge 2 utilizing the elasticity of the resin itself. By opening and closing the lid body 3, , The contents outlet 1a to the fitting plug 4 on the back of the lid 3
It is structured to open and close by. In such a cap, when the lid is opened, the snap hinge 2 pops out to the outside of the cap, and as shown in the drawing, the notch 3a where the snap hinge 2 is fitted to the lid 3 is largely exposed to impair the appearance. Moreover, the notch 3a is formed even when the lid 3 is closed.
There is a problem that the inside can be seen from the gap part and dust and miscellaneous bacteria easily enter from the gap part. Furthermore, since it is integrally molded, the connecting part of the snap hinge 2 and the lid 3 becomes a whitened part by continuous use. It changed and was unfavorable in appearance.

So, in recent years, the cap body and lid are separate parts,
A cap with enhanced appearance is proposed in Japanese Utility Model Application No. 1-168455 (Figs. 8 and 9).

The basic structure of this cap is the same as that of the conventional example, but an outer lid 7 is rotatably supported on the wall portion of the cap body 5 via a thin hinge 6, and a separate part is attached to the back surface of the outer lid 7. The inner lid 8 is attached to allow the lid to have two colors.

[Problems to be solved by the invention] However, the cap still has the following problems to be solved.

That is, also in this cap, since a part of the outer lid 7 is the hinge mechanism 9 portion continuing from the thin hinge 6, a slit is formed on the upper surface of the outer lid 7, and the hinge mechanism 9 is connected by continuous use. The point is that the part becomes white, and the aesthetic appearance of the entire cap is still impaired.

The present invention has been proposed in view of the above circumstances, and it is of course possible to exhibit the advantages of conventional caps, that is, a good snap action effect, an excellent decorative effect by a plurality of colors, and of course, from the top surface of the lid, It is an object of the present invention to provide a cap for a container which can eliminate the notch for the snap hinge and hide the whitened hinge to enhance the aesthetic appearance of the entire cap.

[Means for Solving the Problems] Therefore, in the present invention, a cap body having a content outlet on the upper surface and a rotatably supported by the cap body via a thin first hinge, the content outlet is opened and closed. And a lid that forms a vertical groove that reaches the side of the first hinge and opens on the wall portion of the cap body, and fixes the thin second hinge into the lower end of the vertical groove by fitting it. A thin third hinge is fixed to the lid body in a fitting hole provided in the top plate, and the second hinge and the third hinge are integrally connected by an L-shaped elastic piece.

[Operation] The snap effect of the cap of the present invention is that the center of rotation of the lid is located at the first hinge and the center of rotation of the L-shaped elastic piece is located at the second hinge. It is obtained by elastically deforming the L-shaped elastic piece during the opening / closing operation of the lid.

In addition, since the L-shaped elastic piece is provided with the second hinge and the third hinge at both ends fixed to the cap body and the lid body, the slits on both sides which are necessary for providing the snap hinge are provided. It is absent and can improve the aesthetic appearance and strength of the cap.

Further, the second hinge is located on the side surface of the cap body,
If the third hinge is located at the free end of the lid body, even if each hinge is whitened due to continuous use, the third hinge is located off the upper surface of the lid body, so that the aesthetic appearance of the cap can be maintained.

Moreover, since the amount of deformation of the L-shaped elastic piece due to opening and closing is small, the durability of the L-shaped elastic piece is improved.

From 23, a fitting piece 29a that is locked to the back surface of the top plate portion 20 is formed. Note that such L
The shaped elastic piece 13 is integrally molded together with the second hinge 28 and the third hinge 29 by injection molding, and constitutes one part separate from the lid body 11 and the cap body 10.

 Next, the operation of the cap of the container having the above structure will be described.

According to the cap of this embodiment, the cap body 10 and the lid body
11 and 11 can be integrally formed with the first hinge 12, and the L-shaped elastic portion 13 can be formed into the second hinge 28 and the third hinge 29.
It can be integrally molded together. When assembling this, the second hinge 28 at the rear end of the L-shaped elastic piece 13 is used.
After being fitted and fixed in the fitting hole 27 in the vertical groove 19 of the cap body 10, the third hinge 29 at the tip of the L-shaped elastic piece 13 is closed.
It may be fitted into the fitting hole 23 of 11 and fixed.

This assembly is a simple work of simply fitting and fixing the two members, does not require any special technique or equipment for assembling, and each member can be molded in a large amount with an appropriate synthetic resin or the like. Yes, the cost can be reduced.

The operation of opening and closing this cap is the same as that of a general snap-type cap. That is, as shown in FIG. 1 and FIG. 5, in order to change the closed state in which the lid 11 closes the contents outlet 10a from the closed state to the open state, the finger hanging projection 22 of the lid 11 is moved upward with a finger. Just push it up. By this operation, the lid body 11 rotates in the opening direction about the first hinge 12, but the L-shaped elastic piece 13 integrated with the lid body 11 rotates about the second hinge 28. Due to the difference, the bending of the L-shaped elastic piece 13 is expanded to generate resistance in the opening direction, and the lid 11 is further resisted against this resistance force.
When is rotated, the lid body 11 is suddenly repelled (snap action) in the rotation direction (opening direction) by the elastic return force accumulated in the L-shaped elastic piece 13 in the middle thereof, and as a result, the lid body 11 is moved. It is rotated vigorously to the maximum open state shown in FIGS. 2 and 4.

When the lid 11 is closed by rotating it in the reverse order of the above-mentioned operation, a moment acts on the lid 11 in the closing direction during the rotation due to the same action as described above, and conversely a snap action occurs to close the lid 11. Becomes

As described above, in the cap of the container according to the present embodiment, the second hinge 28 fixed to the lower end of the vertical groove 19 of the cap body 10 and the third hinge 29 fixed to the free end side of the lid 11 exert the snap action. Since they are connected by the elastic piece 13, the slits on both sides for providing the snap hinge are provided on the lid 11 as in the conventional case.
Since the second hinge 28 and the third hinge 29 are located inconspicuously on the edge of the lid 11 and the side surface of the cap body 10, even if they change from whitening to whitening due to continuous use, they will affect the appearance. The influence is small, and therefore the appearance of the cap can be improved and its aesthetic appearance can be maintained. Moreover, since the notch or the like is not formed in the lid body 11, the rigidity of the lid body 11,
The durability is also improved.

Furthermore, since the second hinge 28 is fixed to the rear wall portion of the cap body 10 and the third hinge 29 is fixed to the free end side of the lid body 11, the total length of the L-shaped elastic piece 13 is relatively long. Become. As a result, the resistance gradually changes according to the opening / closing angle of the lid body 11, so that the feeling at the time of opening / closing becomes good, and the amount of deformation of the L-shaped elastic piece 13 associated with opening / closing is small.
The durability of is also improved.

Further, the L-shaped elastic piece 13 is integrally provided with the second hinge 28 and the third hinge 29 at the lower end and the tip thereof, and the cap body 1
0, because it is a separate part from the lid 11, two colors can be arranged, and in particular, by making the top plate portion 25 that substantially covers the entire top surface of the lid 11 a different color, the decoration effect of the cap can be improved. It can be further enhanced.

FIG. 6 shows another embodiment of the present invention, which is different from the above embodiment in that the decorative effect by the L-shaped elastic piece 13 is further enhanced.

That is, in this embodiment, the cap body 30, the lid body 31,
The outer shape of the cap formed by the appearance of the L-shaped elastic piece 32 is a hemispherical shape, and the top plate portion 33 of the L-shaped elastic piece 32 of the upper layer is formed.
With a spherical shape to give a novel decoration effect, the top plate 33 is colored differently from the lower lid 31 and the cap body 30 to enhance the color effect and improve the aesthetic appearance of the cap. .

In this way, by covering the upper surface of the lid body 31 with the L-shaped elastic piece 32, caps of various designs can be obtained,
The degree of freedom in design can be increased.

[Advantage of Invention] As described above, according to the present invention, the cap body having the contents outlet on the upper surface and the cap body are rotatably supported by the thin first hinge to open and close the contents outlet. In a cap of a container provided with a lid, a vertical groove is formed in a wall portion of the cap main body, the vertical groove reaching a side of the first hinge and opening, and a thin second hinge is fitted to a lower end of the vertical groove. Since the third hinge having a small thickness is fixed to the lid body by fitting it into the fitting hole provided in the top plate, the second hinge and the third hinge are integrally connected by the L-shaped elastic piece. In addition to exhibiting a good snap action effect and an excellent decorative effect due to multiple color arrangements, since the slit for the snap hinge is not formed in the lid, the aesthetic appearance of the cap can be improved and the lid can be improved. Body rigidity, The durability is also improved. Moreover, since the second hinge is located on the side surface of the cap body and the third hinge is located at the free end of the lid body, even if each hinge is whitened by continuous use, the aesthetic appearance of the cap can be maintained. Also, the second
Since the hinge is fixed to the rear wall of the cap body and the third hinge is fixed to the free end side of the lid, the L-shaped elastic piece has a relatively long overall length, and as a result, the lid is opened and closed. Since the resistance gradually changes with the angle, the feeling of opening and closing becomes good. Moreover, since the amount of deformation of the L-shaped elastic piece due to opening and closing is small, the durability of the L-shaped elastic piece is also improved. Furthermore, caps of various designs can be obtained by changing the shape of the exposed surface of the L-shaped elastic piece.
