Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a synthetic resin cap, and more specifically to a cap having an elastically reversible lid.

“Prior Art” Conventionally, many caps having elastically reversible lids are known, and a typical one is a cap with a so-called three-point hinge mechanism. The cap connects the upper end of the rear part of the cap body and the lower end of the lid rear part that closes the spout formed in the top wall of the cap with a pair of left and right first hinges at appropriate intervals, and The base end of the inverted L-shaped elastic strip plate provided between the hinges is connected to the rear part of the cap body below the first hinge via the second hinge, and the tip of the elastic strip plate is further connected to the first hinge. It is to be connected to the upper surface of the lid at a position further forward than the third hinge.

[Problems to be Solved by the Invention] The above-mentioned conventional so-called cap with a three-point hinge mechanism has a drawback in that the elastic strip plate largely appears on the upper surface of the lid body to impair the appearance.

According to the present invention, a short peripheral wall is erected from an outer surface of an upper portion of a peripheral wall of a cap body via an outward flange-shaped wall, and a rear peripheral portion of the outward flange-shaped wall and a short peripheral wall portion above the rear portion of the outward flange-shaped wall are cut out. By connecting the upper end of the L-shaped elastic strip plate protruding from the front edge of the cutout portion to the rear part of the lid body, the elastic strip plate is provided inconspicuously, and the dish body is fitted to the upper outer surface of the cap body. Thus, the appearance is improved to enhance the commercial value, and it is also provided as a clue to identify the stored items in the container to which the cap of the present invention is attached.

"Means for Solving the Problem" The first peripheral wall 2 for fitting the neck and neck of the container body, the top plate 3 that closes the upper end surface of the container, a pouring hole 4 is formed in the center, and the upper part of the first peripheral wall 2 is attached. The liquid pouring cap 1 which erects the second peripheral wall 6 from the peripheral edge of the outward flange 5 and the disk 9 placed on the upper surface of the top plate 3 and the through hole 10 in the disk portion above the pouring hole 4. Further, the outer wall 12 is formed from the peripheral portion except the rear portion of the disc 9
And the dish-shaped member 8 in which the outer wall is fitted to the outer surface of the second peripheral wall 6 and the pouring hole 4 are closed by the top wall 14,
A lid 13 having a rear portion of a third peripheral wall 15 suspended from the peripheral edge of the top wall and a rear portion of the second peripheral wall 6 connected to the second peripheral wall 6.
The upper rear edge and the lower rear edge of the third peripheral wall 15 are connected by a pair of left and right first hinges 17, 17 with an appropriate gap, and the second peripheral wall portion and the outward flange portion below the hinge are cut out. An L-shaped elastic strip 20 is extended from the front edge of the cutout portion 18 via a second hinge 19, and the tip of the elastic strip is located at the rear portion of the third peripheral wall 15 above the first hinges 17, 17. On the third hinge 21
, The liquid pouring cap 1 and the lid body.
13 and the dish-shaped member 8 were formed in different colors.

"Operation" From the state shown in FIG. 1, the lid 1 is centered around the first hinges 17,17.
When 3 is rotated in the opening direction, the elastic strip 20 elastically deforms in the expanding direction and then elastically restores after a thought point.
As shown in FIG. 3, the lid is held open. When the lid is rotated in the closing direction from this state, the elastic strip 20 is elastically deformed again and then elastically restored after a thought point, so that the lid is held in the closed state.

“Example” 1 is a liquid pouring cap, and the liquid pouring cap is
A top plate 3 is formed at the upper end of the first peripheral wall 2 for fitting the mouth and neck of the container body, and a pouring hole 4 is formed at the center of the top plate.
The second peripheral wall 6 is erected from the peripheral edge of the outward flange 5 attached to the upper part of the first peripheral wall 2, and the nozzle 7 is erected from the peripheral edge of the pouring hole 4.

A dish-shaped member 8 is fitted on the upper portion of the liquid pouring cap 1. In the dish-shaped member, a disc 9 is placed on the upper surface of the top plate 3, and a through hole 10 is formed in the disc portion above the pouring hole 4, and the nozzle 7 is placed above the through hole. And the inner wall 11 and the outer wall 12 are hung from the lower surface and peripheral edge excluding the rear portion of the disc 9 to fit both inner and outer walls to the upper outer surface of the first peripheral wall 2 and the outer surface of the second peripheral wall 6. I am letting you. The dish-shaped member is formed in a different color from the liquid pouring cap 1 and the lid 13 described later.

A lid 13 is connected to the rear portion of the liquid pouring cap 1.
In the lid, a third peripheral wall 15 is hung from the outer periphery of the top wall 14 to connect the rear portion of the third peripheral wall to the rear portion of the second peripheral wall 6, and the top wall.
14 From the center, hang down a rod-shaped stopper 16 and attach the rod-shaped stopper to the nozzle 7
It is fitted inside. The lid is formed so as to be elastically inverted and opened and closed by a three-point hinge mechanism having a structure different from the conventional one, and the second peripheral wall 6 has a rear upper end edge and a third peripheral wall 15 rear lower end edge, Connected by a pair of left and right first hinges 17 and 17 with an appropriate gap, the second peripheral wall portion and the outward flange portion below the hinges are cut out, and the second hinge 19 is provided from the front edge of the cutout portion 18. Through an L-shaped elastic strip plate
20 and extend the tip of the elastic strip to the first hinges 17,17.
It is connected to the rear part of the third peripheral wall 15 on the upper side via a third hinge 21.

"Effect of device" The present invention has the above-mentioned configuration, and the first peripheral wall 2 of the liquid pouring cap 1
The second peripheral wall 6 is erected from the peripheral edge of the outward flange 5 attached to the second peripheral wall, and the rear upper end edge of the second peripheral wall and the rear lower end edge of the third peripheral wall 15 of the lid 13 are paired with a pair of left and right first hinges 17, 17. Connect
In addition, the second peripheral wall 6 portion and the outward flange 5 portion below both hinges are cut out, and the second hinge is cut from the front edge of the cutout portion 18.
Since the L-shaped elastic strip 20 is extended through 19 and the tip of the elastic strip is connected to the rear part of the third peripheral wall 15 through the third hinge 24, a part of the elastic strip 20 is a rear surface of the cap. Since the elastic strip 20 is not conspicuous and the appearance of the cap is not impaired because the other part is located below the rear part of the cap, the outer surface of the upper part of the liquid pouring cap 1 is prevented. Since the fitted dish-shaped member 8 is formed in a color different from that of the liquid pouring cap 1 and the lid body 13, the appearance of the cap is good and the commercial value is high, and the inside of the container to which the cap of the present invention is attached is high. The contents can be identified by the color of the dish-shaped member 8 as a clue. Further, since the liquid pouring cap 1 and the lid 13 are connected via a hinge, the liquid pouring cap 1 and the lid 13 can be connected to each other. It can be integrally molded, which is extremely advantageous in manufacturing.
