Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to, for example, a container cap, a clip, or the like.
It is made available for various other fields.

“Prior Art” For example, as a cap with a lid plate that is elastically inverted, the upper end of the rear wall of the cap body and the lower end of the rear wall of the lid plate that opens and closes the upper surface of the cap body are horizontally spaced at appropriate intervals. While connecting with thin hinges, a groove for the rear surface and the upper end opening is formed in the rear surface portion of the rear wall of the cap body between the thin hinges, and the upper and front lid plate portions between the thin hinges are formed into a long hole shape. The first thin-walled hinge, which is formed on a portion of the groove 4 and has an inverted L-shaped or arc-shaped elastic plate connected between the lower end of the groove 4 and the front end of the long hole-shaped portion through second and third thin hinges. It is known that when the cover plate is rotated with respect to the cap body, the cover plate is elastically inverted through the dead point.

"Problems to be solved by the invention" Although the main part of this kind of equipment is integrally molded with a synthetic resin material, the conventional structure has a drawback that the mold structure for the integral molding becomes complicated and the cost becomes high. It was

INDUSTRIAL APPLICABILITY The present invention makes it easy to integrally mold and can be formed at low cost, and can be applied to a clip with a lid plate, which has been conventionally used, a clip, or other uses.

"Means for Solving the Problems" The instrument main body 2 having the first frame-shaped portion 1 and the rear wall 10a via the first thin hinge 8 at the upper outer edge of the first frame-shaped rear wall 1a.
An upper plate 9 having a second frame-shaped portion 10 to which lower outer edges of which are connected and closing the upper surface of the instrument body in an openable and closable manner; and a first frame-shaped portion rear wall 1a below the first thin hinge 8. U-shaped part 16 base end through the second thin hinge 14 on the front part of the, and mounting plate part 18 through the third thin hinge 17 on the other end of the U-shaped part.
And a leaf spring portion 15 respectively attached thereto, and the upper plate 9 is elastically reversible through a dead point when it is rotated about the first thin hinge 8 with respect to the instrument body, So that the portion 16 projects forward and the third thin hinge 17 is located on the inner surface side of the rear wall of the second frame-like portion which is located above and in front of the first thin hinge 8.
The mounting plate 18 was fixed to a part of the inner surface of the upper plate 9, and at least the first frame-shaped portion, the second frame-shaped portion and the plate spring portion 15 were integrally molded with a synthetic resin material.

"Operation" For example, in the first embodiment shown in FIGS. 1 to 4,
When the finger hooking piece 13 at the front end of the upper plate 9 which is the cover plate is pushed up with respect to the instrument main body 2 as the cap main body, it rotates about the first thin hinge 8 and opens as shown in FIG. By the action of 15, the force is opened against the bias during the rotation, and when the dead point is reached during the rotation, it is opened up to a predetermined angle by the bias. The same applies when the upper plate is closed.

"Embodiment" First, a first embodiment shown in Figs. 1 to 4 will be described. 1 is a first frame-shaped portion, and the first frame-shaped portion is an outer surface of an upper portion of a peripheral wall 3 of a cap body as a device body 2. It is provided so that it can be fitted. The upper part of the peripheral wall of the cap body is formed in the small diameter portion 4, and a short nozzle 6 is provided at the center of the top wall 5 at the upper end of the peripheral wall. The small diameter portion and the rear portion of the top wall are formed in a concave portion 7 for storing a U-shaped portion described later.

The outer edge of the upper end of the rear wall 1a of the first frame-shaped portion 1 is connected to the outer edge of the lower end of the rear wall 10a of the second frame-shaped portion 10 of the upper plate 9 via the first thin hinge 8. In the embodiment, the upper plate 9 forms a cover plate for the cap body, and has a second top wall 11 on the upper surface of the second frame-shaped portion, and the second bottom wall center lower surface into the nozzle 6 described above. The plug 12 to be fitted is suspended. A finger hook 13 is projected forward from the lower edge of the front end of the second frame-shaped portion serving as the cover plate peripheral wall.

The U-shaped portion 16 base end of the leaf spring portion 15 is connected to the rear wall front surface portion of the first frame-shaped portion 1 via the second thin hinge 14, and the other U-shaped portion is connected. A mounting plate portion 18 is attached to the end portion through a third thin hinge 17, and the mounting plate portion has a U-shaped portion 16 protruding forward as shown in FIG.
Further, the third thin hinge 17 is fixed to a part of the inner surface of the upper plate 9 so that the third thin hinge 17 is located on the inner surface side of the rear wall of the frame-shaped portion 10. In the illustrated example, the mounting plate portion 18 is formed long, a through hole 19 is bored at the tip thereof, and the plug 12 is fitted into the through hole as shown in FIG.

In the above structure, the second thin hinge 14 is located below and in front of the first thin hinge 8, and the third thin hinge 17 is located above and in front of the first thin hinge 8. When the upper plate 9 serving as a cover plate is rotated with respect to the cap body about the first thin hinge 8 in this state, the third thin hinge 17 portion is divided into the second and third thin hinges 14 with the second thin hinge 14 as the center. Regardless of attempting to move along the circular arc b whose radius is the distance between the thin hinges, the position where the third thin hinge 17 is defined by the mounting plate portion 18 is the distance from that position to the first thin hinge 8. Since it will move along an arc b with a radius of
The U-shaped portion gradually elastically deforms with the above rotation, and elastically restores by passing through the dead point to elastically reverse the upper plate 9, and stops when the third thin hinge 17 moves to the point C where both arcs intersect. Will be done.

At least the first frame-shaped portion 1, the second frame-shaped portion 10, and the leaf spring portion 15
And are integrally molded with a synthetic resin material.

The second embodiment shown in FIG. 5 and FIG. 6 shows an example in which the whole is made compact for makeup.

In this embodiment, the cap body of the first embodiment is replaced with a container body, and the plug 12 is replaced with stop pins 12a, 12a. 20 is a mirror.

The third embodiment shown in FIG. 7 and FIG. 8 shows an example applied to an ordinary container with a lid. In the case of the embodiment, there is no need to particularly explain.

A fourth embodiment shown in FIGS. 9 to 11 shows an example applied to a clip for holding a paper piece 24 or the like. In this embodiment, the lower holding plate 21 is attached to the front surface of the first frame-shaped portion 1 to form the instrument main body 2
And the upper holding plate 22 is attached to the front surface of the second frame-shaped portion 10 to form the upper plate 9. A recess 23 is provided in the lower surface of the second top wall 11 on the upper surface of the second frame-shaped portion to fit the mounting plate portion 18, and the through holes formed in the mounting plate portion are fitted to the retaining pins 12a, 12a vertically extending from the recess portion. The mounting plate is fixed by mating. In the case of this embodiment, the entire clip is integrally molded with a synthetic resin material.

"Effects of the Invention" Since the present invention has the above-described configuration, for example, as shown in FIG. 1, the first frame-shaped portion 1, the second frame-shaped portion 10, and the leaf spring portion 15 are provided without fixing the mounting plate 18. Is integrally molded with a synthetic resin material, and the mounting plate can be fixed to the predetermined inner surface of the upper plate 9 after molding, so that the manufacturing is easy and the cost can be reduced. Since it is hidden on the inner surface of the body, it is not exposed to the outer surface as in the conventional case, so that the appearance can be improved.
