By the way, some compact containers have a free stop function in which the lid is held at the angle at that time when the swing of the lid is stopped in the middle. Conventionally, as a configuration for exerting a free stop function, a metal spring pin is used as a shaft portion, and a frictional force is generated between the shaft portion and a hole through which the shaft portion is inserted by the elastic force of the spring pin. ing. However, even if a resin shaft portion is used instead of such a spring pin, it is difficult to obtain an elastic force equivalent to that of the spring pin, and it is difficult to fully exert the free stop function. It is also conceivable to wrap an elastomer or the like around the resin shaft in order to increase the elastic force, but the elastomer or the like is crushed and the elastic force is weakened due to the constant pressure acting, and the free stop function gradually deteriorates. Is expected to be done.

An object of the present invention is to solve such a problem, and to propose a compact container capable of exerting a sufficient free stop function without using a metal spring pin. The purpose.

The present invention is a compact container provided with a container body and a lid made of synthetic resin, and the lid is swingably supported by the container body.
An elastic wall portion connected to either the container body or the lid body,
When the lid is provided on either the other of the container body and the lid and is not in contact with the elastic wall portion when the lid is closed and the lid is swung in the opening direction with respect to the container body, the lid is not contacted. It is a compact container provided with a contact portion that comes into contact with the elastic wall portion and bends the elastic wall portion.

It is preferable to provide a notch portion by cutting out either one of the container body and the lid body so that the adjacent portion can be elastically deformed, and to make the adjacent portion function as the elastic wall portion.

It is preferable that both one end and the other end of the elastic wall portion are connected to either the container body or the lid body.

When the direction from one end to the other end of the elastic wall is the length direction of the contact portion, the middle portion in the length direction of the contact portion protrudes from both ends in the length direction of the contact portion. It is preferably in the shape of an arc.

The contact portion is preferably located between one end and the other end of the elastic wall.

It is preferable that at least one of the elastic wall portion and the contact portion is provided with a non-slip surface.

According to the compact container of the present invention, when the lid is swung in the opening direction with respect to the container, the contact portion comes into contact with the elastic wall portion and bends the lid portion, and as a result, an elastic force acts on the contact portion. , The free stop function can be demonstrated. In addition, when the lid is closed, the contact portion is not in contact with the elastic wall portion, so that the problem that a force always acts on the elastic wall portion and the elastic wall portion remains deformed is prevented, and the deterioration of the free stop function is suppressed. be able to. In addition, it is excellent in recyclability because it does not require a metal spring pin.

Regarding one embodiment of the compact container according to the present invention, (a) is a cross-sectional view taken from a side view, and (b) is a bottom view. (A) is a front view of the compact container shown in FIG. 1, and (b) is a rear view thereof. It is a figure which shows the state which the contact part came into contact with an elastic wall part by swinging a lid body. (A) is a partially enlarged cross-sectional view and (b) is a partially enlarged bottom view showing a state in which the lid is completely opened. Regarding the modification of the compact container shown in FIG. 1, (a) is a cross-sectional view taken from a side view, and (b) is a bottom view.

Hereinafter, an embodiment of the compact container according to the present invention will be described with reference to the drawings. The terms "upper" and "lower" in the present specification and the like basically refer to the orientation of the bottom wall portion (sign 1b) of the container body (sign 1) in a state where it is placed on a horizontal plane (FIG. 1 (FIG. 1). The orientation shown in a). Further, "front" is the side on which the claw portion (sign 3f) of the lid body (sign 3) is located when the lid is closed, and "rear" is the opposite side. Further, "left" and "right" are left-right directions when viewed from the front to the rear.

1 and 2 show an embodiment of a compact container according to the present invention. The compact container 100 of the present embodiment is used when carrying a solid content such as pressed powder obtained by solidifying powdered cosmetics. The compact container 100 includes a container body 1, a lid body 2 (composed of a lid body body 3 and a mirror 4), and a shaft body 5. The container body 1 houses a medium plate (not shown) containing the solid contents, and an applicator 6 used for applying the solid contents.

The container body 1 is made of a relatively hard synthetic resin (for example, acrylonitrile-butadiene-styrene (ABS) resin). As shown in FIG. 1 (b), the container main body 1 has a substantially rectangular shape in a bottom view, and includes a bottom wall portion 1b having a recess 1a in which the central portion of the rear portion is recessed toward the front. As shown in FIG. 1A, on the upper surface of the bottom wall portion 1b, a main body peripheral wall portion 1c that surrounds the periphery of the bottom wall portion 1b and a partition wall portion 1d that divides the inside of the main body peripheral wall portion 1c into a plurality of parts are provided. In the space partitioned by the partition wall portion 1d, the applicator 6 and the middle plate (not shown) are accommodated.

As shown in FIG. 1A, a main body claw portion 1e for holding the lid 2 in a closed state is provided on the front portion of the container main body 1 so as to project forward from the upper end portion of the main body peripheral wall portion 1c. It is provided.

A first notch portion 1f and a second notch portion 1g for notching the container main body 1 are provided at the rear portion of the container main body 1. The first notch portion 1f and the second notch portion 1g cut out the connecting portion between the bottom wall portion 1b and the main body peripheral wall portion 1c in front of the recess 1a so that the adjacent portions can be elastically deformed. .. The first notch 1f extends in the left-right direction and the up-down direction, and the second notch 1g extends in the left-right direction and the front-back direction and is connected to the first notch 1f and is adjacent to these. In front of the recess 1a, an elastic wall portion 1k having a thin plate shape in the front-rear direction and having one end 1h and the other end 1j connected to the container body 1 is formed.

Further, in the rear portion of the container body 1, circular container-side shaft holes 1 m centered on the central axis O are provided on both left and right sides of the recess 1a as shown in FIGS. 1A and 1B.

The lid body 3 is shaped so as to cover the upper surface of the container body 1 when the lid is closed. The lid body 3 is also made of a relatively hard synthetic resin. The lid body 3 includes a plate-shaped top wall portion 3a, a lid peripheral wall portion 3b surrounding the top wall portion 3a, and a stepped portion 3c in which the top wall portion 3a is recessed. The rear portion of the lid peripheral wall portion 3b (the rear portion when the lid is closed so as to cover the upper surface of the container body 1 with the lid body 3) extends downward so as to fit in the recess 1a. Hereinafter, the rear portion of the lid peripheral wall portion 3b is referred to as an extension portion 3b1.

As shown in FIGS. 1A and 1B, circular lid-side shaft holes 3d concentric with the central shaft O of the container-side shaft hole 1m are provided on the left and right side surfaces of the extending portion 3b1. Further, the extending portion 3b1 is provided with a bulging portion 3e extending from directly below the central axis O to the rear and having an arc shape having a cross-sectional shape concentric with the central axis O. The length of the bulging portion 3e in the left-right direction is about the same as that of the elastic wall portion 1k. As for the shape of the bulging portion 3e in the longitudinal direction, as shown in FIG. 1B, the middle portion in the left-right direction (in the present embodiment, the central portion in the left-right direction of the bulging portion 3e) is larger than both ends in the left-right direction. It has a protruding arc shape. The bulging portion 3e is not in contact with the elastic wall portion 1k when the lid body 3 is closed, while the elastic wall is formed by swinging the lid body 3 in the lid opening direction as described later. It is a part that comes into contact with the part 1k. The bulging portion 3e corresponds to a portion referred to as a "contact portion" in the present specification and the like.

Further, the lid body 3 is provided with a lid claw portion 3f as shown in FIG. 1A at the front portion when the lid is closed. As shown in the figure, the lid claw portion 3f engages with the main body claw portion 1e when the lid is closed.

The mirror 4 has a plate shape and a rectangular shape in a plan view, and is attached to the step portion 3c. The mirror 4 is formed by depositing a metal such as aluminum on a plate-shaped base material made of a synthetic resin (for example, acrylic (PMMA) resin or polycarbonate (PC) resin), or by forming a mirror-like seal on the base material. It is formed by sticking.

The shaft body 5 is formed in a columnar shape and is inserted into the container side shaft hole 1 m and the lid side shaft hole 3d. It should be noted that either one of the container-side shaft hole 1 m and the lid-side shaft hole 3d fits and holds the shaft body 5, and the other one slides with respect to the shaft body 5. As a result, the lid 2 is swingably supported with respect to the container body 1. The shaft body 5 can be formed of various synthetic resins, but those having low wear resistance such as polyacetal (POM) resin and polyamide (PA) resin are preferable.

The compact container 100 composed of such members can be assembled in the same manner as the conventional compact container using a spring pin, and since the number of members does not change, it can be assembled as well as in the conventional case. can. Further, the elastic wall portion 1k provided on the container body 1 is not directly visible from the outside by the extending portion 3b1 when the lid is closed (see FIG. 2B), and the first notch portion 1f and the first The two notches 1g are excellent in appearance because they are not directly visible even when the lid is opened by the main body peripheral wall portion 1c located above the notch portion 1g. Further, since the metal spring pin conventionally used is not used and the mirror 4 is made of synthetic resin, when the compact container 100 is discarded, it is made of a synthetic resin member and other materials. There is no need to separate the parts, and it is excellent in recyclability.

Further, in the compact container 100 of the present embodiment, when the lid is closed, the lid claw portion 3f engages with the main body claw portion 1e as shown in FIG. 1, so that the lid 2 is maintained in the closed state. Can be done. Therefore, even when the compact container 100 is carried, the accommodated coating tool 6 and the middle plate (not shown) do not pop out to the outside of the compact container 100. In this state, as shown in FIG. 1A, there is a gap between the extending portion 3b1 and the elastic wall portion 1k, and the elastic wall portion 1k is in a non-contact state. That is, since no force acts on the elastic wall portion 1k, the problem that the elastic wall portion 1k remains deformed is prevented.

On the other hand, when the coating tool 6 is taken out and the solid content contained in the inner plate is applied, the lid 2 is pulled up by putting a finger on the front portion of the lid peripheral wall portion 3b. As a result, the engagement between the claw portion 3f of the lid and the claw portion 1e of the main body is released, so that the lid 2 can be opened.

When the lid 2 is swung in the opening direction, the bulging portion 3e comes into contact with the elastic wall portion 1k and the elastic wall portion 1k begins to bend, as shown in FIG. As a result, the elastic force of the elastic wall portion 1k acts on the bulging portion 3e to generate a frictional force between the two, so that the lid 2 can be held at the angle at that time. Therefore, makeup or the like can be performed while the mirror 4 provided inside the lid 2 is maintained at an angle that is easy to see. In the compact container 100 of the present embodiment, as shown in FIG. 4, the lid 2 can be opened from the time when the lid is closed until it is rotated 180 degrees.

By the way, the elastic wall portion 1k bends toward the front at its intermediate portion, but hardly bends at one end portion 1h and the other end portion 1j. Therefore, if an object that comes into contact with the elastic wall portion 1k strongly presses against the one end portion 1h and the other end portion 1j, the elastic wall portion 1k may be damaged. On the other hand, the shape of the bulging portion 3e in the longitudinal direction in the present embodiment is an arc shape in which the central portion in the left-right direction protrudes from both ends in the left-right direction, and the elastic wall portion 1k naturally bends. Since it is close to the shape (see FIG. 4B), it is possible to prevent the elastic wall portion 1k from being damaged.

In order to prevent the elastic wall portion 1k from being damaged, the bulging portion 3e'as shown in FIG. 5 may be adopted. The bulging portion 3e'has the same cross-sectional shape as the bulging portion 3e, extends linearly in the left-right direction (the cross-sectional shape is the same at any position in the left-right direction), and is an elastic wall. It is located between the one end portion 1h and the other end portion 1j of the portion 1k (in the present embodiment, the center of the elastic wall portion 1k). Since the bulging portion 3e'also does not strongly press against the one end portion 1h and the other end portion 1j, it is possible to prevent the elastic wall portion 1k from being damaged.

The outer surfaces of the elastic wall portion 1k and the bulging portion 3e may be smooth surfaces, but it is preferable that one or both of them are non-slip surfaces. Here, the non-slip surface is a surface that has been subjected to a treatment that increases the frictional force between the elastic wall portion 1k and the bulging portion 3e. In providing such a non-slip surface, for example, the mold forming the container body 1 and the lid body 3 may be textured to give fine irregularities to the outer surface of the elastic wall portion 1k and the bulging portion 3e. However, the mold may be engraved to provide unevenness with a relatively large height on these outer surfaces. Further, the elastic wall portion 1k and the bulging portion 3e may be subjected to surface treatment (for example, painting) capable of increasing the frictional force.

Although one embodiment of the present invention has been described above, the present invention is not limited to the specific embodiment, and unless otherwise specified in the above description, the gist of the present invention described in the claims. Various modifications and changes are possible within the range of. Moreover, the effect in the above-described embodiment is merely an example of the effect resulting from the present invention, and does not mean that the effect according to the present invention is limited to the above-mentioned effect.

For example, in the present embodiment, the elastic wall portion 1k is formed by the first notch portion 1f and the second notch portion 1g, but the first notch portion 1f is extended upward and penetrates the container body 1 in the vertical direction. The elastic wall portion 1k may be formed only by the first notch portion 1f, and the elastic wall portion 1k is not limited to one in which both the one end portion 1h and the other end portion 1j are connected to the container body 1. It may be configured so that only one is connected and cantilevered. Further, the elastic wall portion 1k is not limited to the one formed integrally with the container main body 1, and for example, a differently formed elastic wall portion 1k may be fitted into the container main body 1. Then, the elastic wall portion 1k provided in the container body 1 and the bulging portion 3e provided in the lid body 3 are configured to be interchanged, and the bulging portion (contact portion) is provided in the container body 1 and the lid body 3 is provided with the bulging portion (contact portion). An elastic wall portion may be provided.
