Description

[Detailed description of the invention] "Field of industrial application" This invention relates to, for example, a compact container for storing cosmetics, and in particular to a compact container whose lid can be opened and closed using a snap action. be.

"Prior Art" Conventionally, there are compact containers of this type that utilize a snap action. This compact container has a structure as shown in FIG. 7, for example. That is, the compact container shown in FIG. 7 is disclosed in Japanese Utility Model Publication No. 59-82410, and includes a hinge piece 2 having a pivot shaft 2a at the rear end 1a of the lid 1.
The rear end 3a of the container body 3 is provided with an elastic piece 4 that comes into elastic contact with the tip of the hinge piece 2 during rotation of the lid 1.
By the action of the elastic piece 4 and the elastic piece 4, the lid 1 can be opened and closed on the snap action principle.

``Problem to be solved by the invention'' According to the compact container with the conventional structure described above, there is no need to provide hook mechanisms for both the front wall 3b of the container body 3 and the free end 1b of the lid 1, so the number of parts can be reduced. It is possible to obtain favorable effects such as a reduction in manufacturing costs. However, even with such a compact container, the following problems remain, for example.

That is, the distance from the rotation axis 2a of the hinge piece 2 to the elastic piece 4 is short, and the elastic piece 4 itself is short, so that a sufficient amount of elastic deformation cannot be obtained, so that the effect of the snap action cannot be sufficiently obtained. Moreover, the rotation operation of the lid body 1 was not smooth.

Furthermore, when the lid body 1 is in the closed state, the hinge piece 2 and the elastic piece 4 are locked together only by their contact, so it is difficult to maintain both in a completely locked state. .

This invention was made in view of the above circumstances, and aims to provide a compact container that improves the effect of the snap action and provides smooth rotational operation.

"Means for Solving the Problems" This invention provides a compact container in which the base end of the lid is hinged to one edge of the container body via a rotation shaft, and the lid is An elastic piece extending from the free end of the lid body toward the proximal end is provided on the inner surface, and the rotation axis is provided on this elastic piece, and the height dimension of the inner surface of the lid body from the rotation axis is determined from the rotation axis. A compact container characterized in that the length of the container main body is set to be smaller than the length up to the one edge.

"Operation" When the lid is rotated around its rotation axis to the so-called open state, one edge of the container body presses upward against the inner surface of the proximal end of the lid, and the elastic piece is elastically deformed. I am made to do so. Furthermore, when the inner surface of the proximal end of the lid passes one edge of the container body, the pressure applied by one edge of the container body weakens, and rotation is urged by the snap action due to the elasticity of the elastic piece, further opening the lid. act to become a state. When the lid is closed, a reverse snap action occurs.

"Embodiments" Hereinafter, embodiments of this invention will be described with reference to the drawings.

1 to 3 show a first embodiment of this invention, and in these figures, reference numeral 10 is a container body for storing cosmetics, etc., and reference numeral 11 is a rear wall portion 10a of this container body 10. The base end 11a is a hinged lid, and the container body 10 and lid 11 constitute the main components of the compact container according to this invention.

The container main body 10 is formed into a flat rectangular shape, and has a recess 12 formed in its upper surface for storing cosmetics, and a front wall 10b approximately in the center of the container main body 10. A notch 13 is provided for opening the lid 11 with fingers. Further, protrusions (rotation shafts) 14, 14 for vertically rotatably supporting the base end 11a of the lid 11 are provided on both sides of the rear wall 10a of the container body 10.

Further, the lid 11 is formed into a rectangular plate shape to open and close the recess 12, and has bases on the inner surface of the lid 11 along both side edges from the free end 11b of the lid 11. Approximately L-shaped elastic pieces 15, 15 extending toward the end portion 11a are integrally provided. The tip portions 15a of these elastic pieces 15, 15,
15a is provided with hinge portions 16, 16 for hingedly connecting the lid 11 to the container body 10, and these hinge portions 16, 16 are provided with longitudinally rotating portions 14, 14 of the container body 10. Holes 16a, 16a that can be freely fitted are provided.

Furthermore, in this embodiment, as shown in FIG. Upper edge 17 of wall 10a
This is set to be smaller than the length l of the container body 10, so that when the lid 11 is rotated about the rotation shaft 16a, the inner surface of the rear end 11b of the lid 11 has the upper edge 17 of the container body 10. are pressed against each other and the elastic pieces 15,
15 is designed to be elastically deformed.

Note that both side walls 10c, 10c of the container body 10
When the lid body 11 is closed, the elastic pieces 15, 1
As shown in FIG. 2, both sides of the compact container form a substantially integral plane in the closed state.

Next, the operation of this embodiment configured as above will be explained.

As shown in FIG. 2, to open the lid 11 from the closed state, use your fingers to hook the free end 11b of the lid 11 through the notch 13 of the container body 10 and push it upward. Bye. With this operation,
As shown in FIG. 3, the rear wall portion 10a of the container body 10
The lower surface of the base end 11a of the lid body 11 is pressed against the upper edge 17, and the elastic piece 1 is supported by the protrusion 14.
By elastically deforming 5 and 15, the resistance force against rotational operation begins to increase.

When the lid 11 is further rotated around its rotation axis 16a against this resistance, the pressing force of the upper edge 17 of the container body 10 against the lower surface of the lid 11 is weakened, and the lid is 11 is snapped back (snap action) in the rotating direction (opening direction), and as a result, the lid body 11 is rotated vigorously and becomes the maximum open state.

When closing the lid 11, if the lid 11 is rotated in the reverse order of the above operation, a moment will be applied to the lid 11 in the closing direction by the same action as described above, and a reverse snap action will occur. It becomes closed state.

In the compact container configured as described above, the organic action of the elastic piece 15 and the lid 11 allows the lid 11 to be opened and closed with a single touch, and also in the closed and open states. This state is sufficiently maintained so that the lid body 11 will not be opened or closed inadvertently. Note that when the lid 11 is in the open state, the lid 11 does not return due to the above-mentioned action, so it does not become a hindrance during use, and the usability can be improved.

Further, in the embodiment, since the elastic piece 15 is provided extending from the free end 11b of the lid body 11 to the rear wall portion 11a, a sufficient elastic force of the elastic piece 15 can be secured, and a smaller rotational force can be used. A sufficient and smooth snap action can be obtained.

FIG. 4 shows a second embodiment of this invention, in which elastic pieces 15, 15 are provided closer to the inside of the lid 11, and when the lid 11 is in the closed state, the elastic pieces
Recesses 19 and 19 for accommodating containers 5 and 15, respectively, are provided on the upper surface of the container body 10. According to this configuration, when the lid body 11 is in the closed state, the elastic pieces 15, 15 are housed in the recesses 19, 19 and are not visible from the outside, so that the aesthetic appearance of the compact container can be further improved.

FIG. 5 shows a third embodiment of this invention, in which a notch 20 is provided in the base end 11a of the lid body 11, so that the contact between the base end 11a and the upper edge 17 of the container body 10 is increased from both sides. By providing such a location, the friction surface between the two is reduced and the rotation of the lid body 11 is made smoother.

FIG. 6 shows a fourth embodiment of this invention, in which a slope 21 is provided at the base end 11a of the lid 11 with an angle, so that the base end 11a of the lid 11 is rotated at the beginning and end of the rotation. By slidingly contacting the upper edge 17 of the container body 10, the friction surface is reduced and the rotation of the lid 11 is made smoother.

"Effects of the Invention" As explained in detail above, according to this invention, in a compact container in which the base end of the lid body is hinged to one edge of the container body via a rotation shaft, An elastic piece extending from the free end of the lid toward the proximal end is provided on the inner surface of the lid, and the rotation axis is provided on the elastic piece, and the height of the inner surface of the lid from the rotation axis is: Since the length is set to be smaller than the length from the rotation axis to the one edge of the container body, the following excellent effects can be achieved.
