Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin cosmetic container in which a lid is hinged to a container body.
[0002]
[Prior art]
In general, a cosmetic container called compact is used for carrying cosmetics. The cosmetic container contains the cosmetic in the container body and is a lid that is hinged to the rear end of the container body. In general, the closed state of the lid body is maintained by opening and closing the upper side of the container body and engaging a hook provided between the front end portions of the container body and the lid body.
[0003]
In the cosmetic container, both the container body and the lid are formed of a synthetic resin, thereby facilitating manufacturability and reducing the weight of the entire container and diversifying the decoration.
[0004]
[Problems to be solved by the invention]
However, in such a conventional cosmetic container, even when the container main body and the lid are formed of synthetic resin, the hinge pin serving as the rotation center of the hinge is generally formed of metal. Yes. By the way, such cosmetic containers are discarded as garbage when they are used or damaged, but such synthetic resin products are collected separately for recycling, which has been particularly demanded in recent years. It is desirable to be able to do it. However, as described above, since the hinge pin is made of metal with respect to the container body and the lid made of synthetic resin, it is necessary to remove the hinge pin and perform processing when sorting and collecting. In particular, since this hinge pin is pressed into the hinge, it is necessary to destroy the hinge part each time to take out the hinge pin. It takes a lot of time to remove the hinge pin. There was a problem.
[0005]
Accordingly, the present invention has been made in view of such conventional problems, and the hinge pin is made of a synthetic resin like the container body and the lid body, making it unnecessary to remove the hinge pin and facilitating separate collection. It is an object of the present invention to provide a cosmetic container that compensates for a decrease in strength in the case of using synthetic resin as a container body and a lid.
[0006]
[Means for Solving the Problems]
To achieve this object, a cosmetic container according to claim 1 of the present invention includes a synthetic resin container body in which cosmetics are stored, and a synthetic resin lid body that opens and closes the container body, In the cosmetic container in which a hinge pin that opens and closes the lid body is inserted across the protrusions projecting from the container body and the end of the lid body, the hinge pin is formed of a synthetic resin, while the hinge pin is An annular concave portion and an annular convex portion are formed between the projections of the container body and the lid body to be inserted, around the hinge pin so as to be closely fitted to each other so as to be relatively rotatable.
[0007]
In the cosmetic container according to claim 2 of the present invention, a cutout portion into which the annular convex portion can be fitted is formed around the annular concave portion along the radial direction thereof.
[0008]
The operation of the cosmetic container of the present invention having the above configuration will be described below. In claim 1, since the hinge pin that hinges the container body and the lid is formed of synthetic resin, when the cosmetic container is discarded as garbage In addition, it is not necessary to remove the hinge pin each time, and the separate collection becomes remarkably easy. In addition, when a hinge pin made of synthetic resin is used, the strength of this hinge pin is lower than that of a conventional metal pin, but between the projections of the container body and the lid body through which the hinge pin is inserted. In addition, since the annular recess and the annular projection are formed around the hinge pin so as to be closely fitted to each other so as to be relatively rotatable with each other, an excessive shearing force that may act on the hinge pin is caused by the annular pin. It can be received and supported by the concave portion and the annular convex portion. Therefore, since most of the shearing force that can act on the hinge pin when opening and closing the lid can be handled by the container body and the lid, the hinge pin made of synthetic resin is prevented from being damaged. Can do.
[0009]
According to a second aspect of the present invention, when the annular convex portion is fitted into the annular concave portion, the annular convex portion is formed around the annular concave portion by forming a cutout portion into which the annular convex portion can be fitted along the radial direction. Both can be easily fitted by inserting from the notch. The annular concave portion and the annular convex portion that are fitted to each other are smoothly relatively rotated around the hinge pin without the annular convex portion being detached from the annular concave portion.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 to 5 show an embodiment of a cosmetic container according to the present invention, FIG. 1 is a side sectional view of the cosmetic container, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. FIG. 4 is an enlarged side sectional view showing a hinge part in a state where a lid is opened, and FIG. 5 is an exploded perspective view showing an enlarged main part of the hinge part.
[0011]
That is, as shown in FIGS. 1 and 2, the cosmetic container 10 of the present embodiment includes a container body 12 formed in a dish shape for storing cosmetics outside the figure, and a lid for opening and closing the container body 12. The container body 12 and the lid body 14 are each formed of a synthetic resin.
[0012]
A pair of first protrusions 16 project from both ends at the rear end (right end in the figure) of the container body 12, and between the first protrusions 16 at the rear end of the lid body 14. A second protrusion 18 is provided so as to be closely fitted to the first protrusion 18. And in the state which fitted these 1st projection parts 16 and the 2nd projection parts 18, by inserting a pair of hinge pins 20 across both the 1st, 2nd projection parts 16 and 18 from both sides coaxially, A hinge 22 is configured, and the lid body 14 is hinged to the container body 12 so as to be openable and closable around the hinge 22, that is, the hinge pin 20.
[0013]
A hook 24 is formed between the container main body 12 and the front end portion (left end portion in the figure) of the lid body 14, and the closed state of the lid body 14 is maintained by the engagement state of the hook 24. Yes. The hook 24 includes a first protrusion 24 a formed on the rear wall of the recess 12 a formed at the front end of the container body 12, and a second protrusion 24 b suspended from the front end of the lid body 14. The first protrusion 24a and the second protrusion 24b can be engaged and disengaged by the elastic force of the protrusion 24b.
[0014]
Here, in this embodiment, the hinge pin 20 is formed of a synthetic resin, and pin holes 16a and 18a formed continuously in the first protrusion 16 and the second protrusion 18 as shown in FIG. And press fit. By this press-fitting, the hinge pin 20 is prevented from being removed from the pin holes 16a and 18a, and when the lid body 14 is opened and closed, the hinge pin 20 is attached to one of the first protrusion 16 or the second protrusion 18. In a fixed state, it is rotated relative to the other while producing a rotational resistance.
[0015]
Further, between the first protrusion 16 and the second protrusion 18 into which the hinge pin 20 is inserted, as shown in FIG. An annular recess 26 and an annular projection 28 that are closely fitted to each other are formed. The annular protrusion 28 is formed on the first protrusion 16, and the annular recess 26 is formed on the second protrusion 18, and the radial direction around the annular recess 26 (protrusion) is as shown in FIG. A cutout portion 30 into which the annular convex portion 28 can be fitted is formed.
[0016]
The notch 30 is formed in a fan shape, and the outer periphery of the fan-shaped notch 30 is formed to have a width larger than the outer diameter of the annular protrusion 28, and the inner periphery of the notch 30 is formed of the annular protrusion 28. A width slightly smaller than the outer diameter, that is, the peripheral edge of the annular recess 26 is elastically deformed by strongly pushing the annular protrusion 28, and the width is formed to allow the passage of the annular protrusion 28. The notch portion 30 is not limited to a fan shape, and the outer peripheral portion is formed to have a width large enough to fit the annular convex portion 28 without difficulty, and the inner peripheral portion pushes the annular convex portion 28 with a little force and passes therethrough. Any shape may be used as long as it can be formed to a width as small as possible.
[0017]
With the cosmetic container 10 according to the present embodiment having the above-described configuration, the synthetic resin container body 12 and the lid body 14 can be opened and closed via the hinge 22, and the hinge pin 20 of the hinge 22 is the same. Therefore, when the cosmetic container 10 is discarded as separated and collected as waste, it is not necessary to remove the hinge pin 20 each time. In other words, separation of the hinge pin 20 that is difficult to remove becomes unnecessary, so that separate collection is significantly facilitated.
[0018]
In this embodiment, since the hinge pin 20 is made of synthetic resin, the strength of the hinge pin 20 is lower than that of a conventional metal, but the first protrusion through which the hinge pin 20 is inserted. Since the annular recess 26 and the annular projection 28 are formed between the portion 16 and the second protrusion 18 so as to surround the hinge pin 20 and are closely fitted to each other so as to be relatively rotatable with each other. It is possible to receive and support the excessive shearing force that may act on the annular recess 26 and the annular projection 28. Therefore, most of the shearing force that can act on the hinge pin 20 when the lid 14 is opened and closed can be handled by the annular recess 26 and the annular projection 28, that is, the container body 12 and the lid 14. It is possible to prevent the hinge pin 20 made of synthetic resin from being easily damaged.
[0019]
Further, in the present embodiment, the fan-shaped notch 30 is formed around the annular recess 26 along the radial direction, and the other-side annular projection 28 is inserted from the notch 30. When the annular protrusion 28 is fitted to the recess 26, the fitting can be easily performed without forcibly pushing the first protrusions 16 apart. Therefore, the assembling operation of the cosmetic container 10 becomes easy, and as a result, productivity can be improved. Further, the fan-shaped notch 30 has an inner peripheral portion formed with a width slightly smaller than the outer diameter of the annular protrusion 28, so that the annular protrusion 28 is detached from the annular recess 26 when the lid 14 is opened and closed. The concave and convex portions 26 and 28 are smoothly rotated relative to each other about the hinge pin 20.
[0020]
By the way, in the present embodiment, as the annular recess 26 and the annular projecting portion 28, those having a cylindrical shape along the axial direction of the hinge pin 20 have been disclosed. The fitting portion between the ring 26 and the annular convex portion 28 can be spherical. Thus, by making the annular concave portion 26 and the annular convex portion 28 into a spherical fitting, these fitting operations can be further facilitated, and in some cases, the notch portion 30 can be made unnecessary. Further, a tapered fitting structure may be used instead of the spherical fitting.
[0021]
Incidentally, in each of the above embodiments, the cosmetic container 10 having the simplest structure is generally described as an example. Of course, the cosmetic container 10 is not limited to this cosmetic container 10, but the cosmetic refilling inner dish in the container main body 12 is used. It is free to have a function of storing a refill container, a structure in which a refill container is stored, and other functions. The present invention can be applied as long as it is a cosmetic container that is hingedly connected to the lid 14 by the hinge pin 20, and further, the present invention can be applied to a refill container having a similar configuration.
[0022]
In each of the above embodiments, the case where the first protrusion 16 on the container body 12 side is disposed on the outside and the second protrusion 18 on the lid 14 side is disposed on the inside is disclosed. The first protrusion 16 may be disposed on the inner side, and the second protrusion 18 may be disposed on the outer side.
[0023]
【The invention's effect】
As described above, in the cosmetic container according to claim 1 of the present invention, the hinge pin that hinges the synthetic resin container main body and the lid is made of the synthetic resin in the same manner as the container main body and the lid. Since it is formed, it is not necessary to remove the hinge pin each time when the cosmetic container is disposed as waste by separating and collecting, and recycling can be greatly promoted. In addition, an annular recess and an annular protrusion are formed between the projections of the container body and the lid, through which the hinge pin is inserted, so as to surround the hinge pin and be closely fitted to each other so as to be relatively rotatable. Therefore, excessive shearing force that may act on the hinge pin can be received and supported by the annular recess and the annular projection, and the strength reduction when the hinge pin is made of synthetic resin can be reduced. And can be compensated for by the annular projection. That is, most of the shearing force that can act on the hinge pin when opening and closing the lid can be handled by the annular recess and the annular projection, that is, the container body and the lid, so that the hinge made of synthetic resin It is possible to prevent the pins from being damaged.
[0024]
Further, in the cosmetic container according to claim 2 of the present invention, since the cutout portion into which the annular convex portion can be fitted along the radial direction is formed around the annular concave portion, the annular convex portion is formed in the annular concave portion. Can be easily fitted by inserting the annular convex portion from the cutout portion. Therefore, the assembly operation of the cosmetic container is facilitated, and as a result, productivity can be improved.
