Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cap with a nozzle hole that is fitted into the mouth and neck of a container body.

``Prior Art'' A cap with a nozzle hole usually leaves the nozzle hole open, and especially when it is desired to close the nozzle hole, a mouth cap is fitted to the tip of the nozzle.

``Problems that the invention seeks to solve'' If a cap is left open with its nozzle hole open, liquid will leak from the nozzle hole when the container falls over, and if a cap is fitted onto the nozzle, the cap cannot be attached or removed. It was troublesome.

Therefore, an object of the present invention is to provide a cap that can easily and reliably open and close the nozzle hole using an elastically reversible lid plate.

"Means for Solving the Problems" In order to achieve the above object, the present invention, as shown in the drawings, involves fitting the lower half of the peripheral wall 4 hanging down from the periphery of the top wall 3 into the mouth neck of the container body. A cap body 1 having a joint 5 formed therein, a recess 6 formed in the front surface of the upper part of the peripheral wall, and a nozzle hole 8 bored in the recess, and a flat plate fitted into the recess with the nozzle hole closed. A part of the upper edge of the lid plate is connected to the front edge of the top wall at the upper end of the recess via a thin first hinge part 10, and a part of the upper edge of the lid plate 2 is connected to the front edge part of the top wall of the upper end of the recess through a thin first hinge part 10. One end of an elastic plate part 11 having an L-shaped longitudinal section is coupled to the outer surface of the lid plate located thereon via a thin second hinge part 12, and the other end of the elastic plate part is connected to the rear side of the first hinge part. It is connected to the upper surface of the top wall of the cap main body located at
The present invention is characterized in that by rotating the lid plate around the hinge portion, the lid plate can be elastically reversed by elastic deformation of the elastic plate portion.

"Operation" When the lid plate 2 is rotated from the state shown in FIGS. 1 and 2 in the direction of opening the lid around the first hinge part 10 when the container is used, the elastic plate part 11 rotates the lid plate a predetermined amount. It is forcibly expanded and deformed up to the corner, and after the above rotation angle, it contracts and closes due to its own elastic force. As a result, the lid plate is always urged in the lid opening direction as shown in FIG. 3, and the lid opening state is maintained. That is, the nozzle hole 8 is opened.

When the container is not in use, the lid plate in the opened state may simply be rotated in the direction of closing the lid. As a result, the elastic plate portion 11 performs the same operation as described above, and this time the lid plate is constantly biased in the lid closing direction, so that the lid closed state is maintained. That is, the nozzle hole is blocked.

Embodiment FIGS. 1 to 3 show an embodiment of the present invention, in which 1 is a cap body, 2 is a lid plate, and these are integrally molded using a synthetic resin material.

In the cap body 1, the lower half of a peripheral wall 4 extending vertically from the periphery of the top wall 3 is formed into a threaded portion 5 that engages with the mouth and neck of the container (not shown), and a recess 6 is formed in the front surface of the upper part of the peripheral wall. A short cylindrical portion 7 is projected from the center of the upper part of the recessed portion, and a nozzle hole 8 is bored therein. In the illustrated example, the inner surface of the nozzle hole is formed into a tapered surface with a small front diameter, and the opening area of the rear end of the nozzle hole is increased as much as possible. That is, by opening the rear end of the nozzle hole to the upper edge of the inner surface of the peripheral wall 4, the contents of the container do not remain in the cap body during shaking out, so that most of the contents can be discharged.

Inside the recess 6 is a substantially T-shaped flat cover plate 2.
The nozzle hole 8 is closed and fitted with a plug portion 9 projected from the upper part of the inner surface of the lid plate.

The lid plate 2 connects the upper edge of the central plate portion 2a to the top wall 3 at the upper end of the recess via the thin first hinge portion 10.
It is attached to the front edge. Further, one ends of the left and right pair of L-shaped vertical section elastic plate parts 11, 11 are coupled to the upper end edges of the left and right protruding plate parts 2b, 2b of the lid plate via thin second hinge parts 12, 12. The other ends of the elastic plate portions are connected to the upper surface of the top wall of the cap body behind the first hinge portion 10 via thin third hinge portions 13, 13, respectively.

By rotating the lid plate around the first hinge part 10, the lid plate can be elastically reversed in the lid opening direction by an elastic reversing hinge mechanism composed of the elastic plate part and the first hinge part. ing.

In the illustrated example, the elastic plate portions 11, 11 are formed as separate pieces from the cap body 1 and the lid plate 2. Further, reference numeral 14 in the figure is a gap for finger hook defined by the lower surface of the recess and the lower end surface of the lid plate.

"Effects of the Invention" As explained above, according to the present invention, the nozzle hole is opened and closed by the lid plate that opens and closes using the elastic reversing hinge mechanism. Since there is no wobbling of the plate, opening and closing of the cover plate relative to the nozzle hole becomes more reliable.
