Description

[Detailed Description of the Invention] This invention relates to a cosmetic container, and particularly to a container for storing a paste cosmetic such as cream.

Conventional cosmetic containers of this type are generally configured to open and close by removably screwing the threaded part of the lid into a threaded part formed at the opening of the container body. . The lid of this container is opened and closed by holding the container body with one hand and rotating the lid in the opening/closing direction with the other hand. Since the opening and closing operations required the use of both hands, there were problems in terms of speed and ease of opening and closing operations. Particularly in recent years, as cosmetics have become increasingly diverse, multiple cosmetics are often used at the same time.As a result, there is a growing demand for containers that can be opened and closed with easier operation. I felt regret that I could not meet this request.

Furthermore, as shown in Japanese Utility Model Application Publication No. 57-128908, a compact container is provided in which the engagement between the lid and the container body is released by pressing the top surface of the lid. In this compact container, the pressing part of the lid is limited to a part of the front, and a large pressing force is required.Furthermore, after pressing the lid and releasing its engagement, it is difficult to touch the front end of the lid with your finger. This requires an operation such as hanging and opening, resulting in poor opening operability.

This idea was made in view of the problems with the conventional technology mentioned above, and its purpose is to open and close the lid with one-handed operation, by lightly pressing the relatively wide center part of the top surface of the lid. Our purpose is to provide cosmetic containers.

Hereinafter, a cosmetic container according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a longitudinal cross-sectional view of a cosmetic container according to an embodiment of the present invention. A middle frame 4 which is hinged to an outer threaded part 3a on the outer periphery of the upper cylindrical neck part 3 with an inner threaded part 4a on the inner periphery and forms a part of the main body, and an engaging part between the main body 2 and the middle frame 4. A packing 5 that intervenes and holds the two members in a watertight and airtight manner, and a hinge part 9 that is fitted into a notch 7 formed in the rear end of the peripheral wall 16a of the middle frame 4 and supported pivotally by a pin 12. A lid body 8 having at the rear end
A second tapered surface 14 having a predetermined circumferential length is formed at the upper end edge of the peripheral wall 16a, which is located in an axially symmetrical position (front end position) with the notch 7 of the inner frame. A second tapered surface 1 is provided on the front edge of the body 8.
A first tapered surface 13 having a width, a circumferential length, and an inclination angle corresponding to 4 is formed. Second
The tapered surface 14 of the lid 8 is an inclined surface that slopes upward toward the outer radial direction, and the first tapered surface 13 is an inclined surface that slopes downward toward the inner radial direction. They are formed so that they come into surface contact when closed. As shown in FIG. 2A, the lid body 8 has a hinge portion 9 at the rear.
Also, a locking piece 15 is provided on the lower surface of the front end, and a locking claw 15a is formed on the inner surface of the locking piece 15.
The main body 8a of the lid 8 has a shape that curves upward only in one direction from the rear to the front (from the hinge part 9 to the position of the locking claw 15a), and when the lid main body 8a is pressurized from above to below. It is designed to elastically deform and stretch in the front-back direction, and returns to its original shape when pressure is released. As shown in Figure 2B, the middle frame 4 is
a cylindrical base 17 having an internal threaded portion 4a on its inner periphery;
The peripheral wall 16a is formed on the upper part of the base 17, and a protrusion 16b is provided inside the front end of the peripheral wall 16a, in which a locking part 16c that engages with the locking claw 15a of the lid 8 is formed. There is. The upper edge 16d of the peripheral wall 16a is curved upward at a predetermined curvature from the rear to the front so as to match the shape of the peripheral edge of the lid 8, and when the lid 8 is closed, the upper edge 16d The portion 16d (including the second tapered surface 14) is in close contact with the peripheral portion of the lid body 8 (including the first tapered surface 13). The packing 5 is made of an elastic body having cushioning properties, and is integrally formed with a horizontal ring-shaped part 5a and a cylindrical part 5b, as shown in FIG. 2C. The horizontal ring-shaped portion 5a is the middle frame 4
The cylindrical portion 5b is held between the lower surface of the peripheral wall 16a and the upper end surface of the neck portion 3 of the container body 2.
It is in close contact with the inner wall of a. Reference numeral 6 denotes an undercut portion, which is a protruding edge portion 16e on the inner diameter side of the peripheral wall 16a.
are fitted to lock the packing 5 to the middle frame 4. As shown in FIG. 2D, the container body 2 has an external threaded part 3 on the outer periphery of the neck part 3 that is screwed into the internal threaded part 4a of the middle frame.
a, and the middle frame 4 is screwed and fixed with the packing 5 interposed therebetween.

Next, Figure 3 A and B show the hinge part 9 of the lid body 8 and the middle frame 4.
A recess 10 is formed in one end surface in the circumferential direction of the hinge part 9, and this recess 10
There is a through hole 1 from the bottom surface to the other end surface of the hinge part 9.
8 is formed. Further, insertion holes 7a and 7b for pins 12 are passed through both side walls of the notch 7 of the middle frame, respectively, and the insertion holes 7a and 7b are connected to the straight pins 12.
It has a directionality that allows for immediate insertion. Reference numeral 11 is a coil spring serving as an elastic means;
The spring 11 is positioned and held within the recess so that the central hollow portion thereof communicates with the through hole 18. Then, one end protrusion 11a of the spring 11 is inserted into the recess 1.
After fitting the hinge part 9 into the notch part 7 so that the other end protruding part 11b, which is perpendicular to 11a, comes into contact with the inner wall of the notch part 7, the spring is inserted from the insertion hole 7a. By inserting the pin 12 into the insertion hole 7b through the central hollow part and the through hole 18, the pivoting of the lid 8 to the middle frame 4 is completed. The lid body 8 pivotally attached in this way has a spring 11
Therefore, it is always biased in the opening direction.
In addition, if desired, it is also possible to form the middle frame 4 integrally with the container body 2.

The opening/closing operation of the lid 8 of the cosmetic container 1 having the above configuration will be explained based on FIGS. 1 and 4 A and B. In the closed state shown in FIG. The locking claw 15a of the stopper piece 15 and the middle frame 4
The locking portion 16c of the protrusion 16b is elastically engaged with the first
The tapered surface 13 and the second tapered surface 14 are in surface contact, and the inside of the container body is watertightly and airtightly sealed from the outside by the packing 5 that is in close contact with the lower peripheral edge of the lid 8. There is. Next, the lid body 8
When pressed from above as shown by the arrow, the lid 8
is deformed downward by an amount A, and the lid body 8 is extended in the front-rear direction by the amount of downward deformation A. Since the rear end of the lid 8 is pivotally attached, the tapered surface 13 of the front end of the lid eventually moves in the outer diameter direction (upward) on the tapered surface 14 of the middle frame 4 due to this longitudinal stretching force. B
The engagement between the locking pawl 15a and the locking portion 16c is released. At the same time, the opening force of the spring 11 causes the lid 8 to open upward. Also,
When closing, the lid 8 may be pressed in the closing direction to engage the locking claw 15a and the locking portion 16c.
Therefore, both the opening and closing operations can be performed with a single touch with one hand.

In the above embodiment, the elastic means for biasing the lid body 8 in the opening direction is formed from the coil spring 11, but various other types of elastic means are possible. For example, the inner frame 4 may be made of rubber, etc. It is also possible to fix an elastic piece and bias the lid body 8 with the elastic piece.

As mentioned above, in the cosmetic container according to the present invention,
The rear end of the lid is pivoted to the rear of the upper opening of the container body, and the lid is curved in only one direction from the rear end to the front end, and the front end of the lid is curved in only one direction. A locking pawl and a first tapered surface are formed along the front end periphery, and a locking portion that engages with the locking pawl to hold the lid in the closed position is provided at the front end of the container body. A second tapered surface that comes into contact with the first tapered surface when the body is in the closed position is formed on the front end periphery, and an elastic means is provided for biasing the lid toward the open position, and the upper surface of the lid is pressed downward in the closed position. When pressed, the lid stretches forward due to elastic deformation, and the first tapered surface slides on the second tapered surface, thereby releasing the engagement between the locking pawl and the locking portion, and at the same time, the elastic means Since the lid is opened by the button, the lid can be opened with an extremely simple one-touch operation of just lightly pressing the approximate center of the lid.
In addition, even after use, all you have to do is rotate the lid in the closing direction and elastically engage the locking claw and the locking part.
Compared to conventional cosmetic containers, it can be opened and closed very quickly with one hand, and has excellent effects.
