Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a cap with an auxiliary lid that is elastically inverted and used for liquid dispensing containers, etc.

``Prior art'' This type of cap has an auxiliary lid attached to the upper rear end of the cap body with a spout hole, which opens and closes the top surface of the cap body via an elastic mechanism. A so-called three-point hinge, in other words, connects the upper end of the rear surface of the cap body and the lower end of the rear surface of the auxiliary lid with two first hinges at appropriate intervals, and connects the rear surface of the peripheral wall of the cap body below between the two first hinges. , an arc-shaped or inverted L-shaped elastic band plate is provided on the upper surface of the auxiliary lid in front of the first hinge, a second hinge is provided at the connection portion between the lower end of the band plate and the peripheral wall of the cap body, and a second hinge is provided between the front end of the band plate and the auxiliary lid. A third hinge is provided at the connecting portion with the auxiliary lid, and when the auxiliary lid is opened and closed around the first hinge, the elastic band plate is elastically deformed and the auxiliary lid is elastically reversed.

``Problems to be solved by the invention'' The cap of the conventional structure described above connects one end of a relatively long elastic band plate to the cap body and the other end to the auxiliary lid in a bendable manner. The elastic band is elastically deformed, but since the elastic band was designed to return to its original shape when the auxiliary lid is opened and closed, the elastic fatigue of the elastic band allows for accurate return to its original shape, and therefore accurate auxiliary operation. There was a drawback that it was difficult to return to the lid open/closed state.

In this case, the elastic deformation plate, which corresponds to the conventional elastic band plate, is installed so that it can be elastically reversed together with the auxiliary lid, so that elastic fatigue is small, and even if elastic fatigue occurs, the auxiliary lid can accurately return to the open/close state and open/close. This is to prevent the auxiliary lid from rattling against the cap body when the cap body is in a closed position.

"Problems to be Solved by the Invention" In a cap equipped with an auxiliary lid that opens and closes the upper surface of the cap body by elastically inverting with respect to the cap body with a spout hole, either one of the cap body 1 or the rear surface of the peripheral wall of the auxiliary lid 9 , a vertical groove 5 is provided vertically, and first bent portions 6, 6 are provided on both left and right edges of the vertical groove.
The left and right edges of the elastically deformable plate 7 are attached to the left and right side edges of the elastically deformable plate 7 by extending the middle part of the elastically deformable plate backward, and the claw portions 12 attached to the rear surface of the other peripheral wall are attached to the upper or lower end edge of the elastically deformable plate. The lower edge or the upper edge
They were connected via the bending part 13.

``Function'' When the auxiliary lid 9 is closed, as shown in FIGS. 1B and 4, the middle part of the elastic deformation plate 7 protrudes toward the rear of the cap. When raised, the auxiliary lid 9 rotates relative to the cap body around the straight line connecting the upper ends of the first bending parts 6, 6, and the claw portion 12 attached to the cap body 1 or the auxiliary lid 9 rotates. The elastically deformable plate 7 is deformed against its elasticity, and when the dead center is exceeded, the middle part of the elastically deformable plate bulges out toward the front side of the cap due to elastic return, and the third bending part 13 is held in place by the claw. Since the auxiliary lid 9 moves forward together with the lower edge, the auxiliary lid 9 is opened as shown in FIGS. 1A and 3 and maintained in this state. By pushing up the auxiliary lid from the opened state, the elastic deformation plate acts in the opposite manner to the above and closes the top surface of the cap body.

``Embodiment'' First, the first embodiment shown in FIGS. 1A to 2 will be described. Reference numeral 1 denotes a cap body, and a peripheral wall 4 for fitting the mouth and neck of the container extends from the periphery of the top wall 3 with the spout hole 2.
be installed vertically. At the rear of the peripheral wall, a vertical groove 5 is provided vertically in a substantially V-shape with an open groove at the upper end. An elastic deformation plate 7 is disposed above the vertical groove via the first bending portions 6, 6.
The left and right edges of the elastically deformable plate are attached so that the intermediate portion of the elastically deformable plate extends rearward. In the illustrated example, the middle part is the second bending part 8, but this is not necessarily necessary and may be curved in an arc shape.

Reference numeral 9 denotes an auxiliary lid that suspends the peripheral wall 11 from the second top wall 10. A claw portion 12 projects rearward from the rear lower surface of the peripheral wall, and the elastic deformation plate 7 is attached to the lower end surface of the claw via a third bending portion 13. The upper edge is joined. The claw portion has a length that allows it to push down the elastically deformable plate 7 against its elasticity and move in the opposite direction when opening and closing the auxiliary lid. A stopper 14 that can be attached to and removed from the spout hole 2 as described above hangs from the back side of the second top wall 10, and a finger plate 15 for opening and closing the auxiliary lid protrudes from the lower front end of the auxiliary lid peripheral wall.

The embodiment shown in FIGS. 3 and 4 has a vertical groove 5 and an elastically deformable plate 7 on the auxiliary lid peripheral wall side, contrary to the first embodiment.
and a claw portion 12 is provided on the side of the cap body, and even in this case, the same effect as in the first embodiment can be achieved.

``Effect of the invention'' This proposal has the structure already described, and unlike the conventional one,
The elastically deformable plate of the cap with an auxiliary lid that can be elastically inverted is designed to be elastically inverted together with the auxiliary lid when the auxiliary lid is opened and closed, so that elastic fatigue is small and even if the auxiliary lid is subjected to elastic fatigue, the auxiliary lid will not rattle against the cap body. It rarely happens.
