Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a container fitting cap formed so that a stored item in the container can be poured out from a nozzle hole.

"Prior Art" In a cap with a nozzle hole, the nozzle hole is usually left open, and a mouth cap is fitted to the tip of the nozzle particularly when it is desired to close the nozzle hole.

"Problems to be solved by the invention" Caps with nozzle holes left open leak liquid when the container collapses, and those with mouth caps fitted to the nozzles are difficult to attach and detach. there were.

According to the present invention, an elastic lid plate is integrally formed with a cap body, the nozzle hole is opened and closed by elastic inversion of the elastic lid body, and the elastic lid body is positioned at the open / close position, and the elastic lid body is rocked or rattled to close the nozzle hole. It is provided so that the elastic lid does not prevent the nozzle hole from opening or opening.

"Means for Solving the Problem" The lower half of the peripheral wall 3 suspended from the peripheral edge of the circular top wall 2 is formed in the fitting portion to the mouth neck portion of the container body, and the concave portion 4 is formed in the upper front surface of the peripheral wall. The cap main body 1 is provided with a nozzle hole 6 in the recess, and the elastic cover plate 8 having an arcuate cross section is fitted in the recess by closing the nozzle hole. Is connected to the front edge of the top wall at the upper end of the recess via the thin hinge portion 10, and the connecting portion is rotated around the thin hinge portion so that the elastic lid plate can be inverted upside down by elastic inversion over the top wall 2. The curvature and the length in the circumferential direction are determined, and the cap body and the elastic cover plate 8 are integrally molded with a synthetic resin material.

[Operation] When the elastic cover plate 8 is rotated upward from the state shown in FIG. 1 about the thin hinge portion 10, the elastic cover body is elastically inverted and inverted as shown in FIG. In this state, the elastic lid plate portion near the thin hinge portion and the elastic lid plate portion on the upper end side in FIG.
It becomes an arc shape in the opposite direction. However, depending on the thickness of the elastic lid plate, the elastic lid plate portion on the upper end side in FIG. 2 may be elastically inverted to form an arc similar to the elastic lid plate portion near the thin hinge portion. When the elastic lid plate portion on the upper end side of FIG. 2 is pushed forward, that is, leftward in the figure from the state of FIG. 2, the elastic lid plate portion near the thin hinge portion elastically deforms and when the dead point is exceeded, The restoring force restores the upright state as shown in FIG. 1, and the nozzle hole 6 is closed.

[Example] The cap of the present invention is made of a synthetic resin material including a cap body and an elastic lid plate integrally formed with the cap body.

The cap body 1 has a circular top wall 2 and a peripheral wall 3 vertically extending from the periphery.
The lower half of the container is formed into a threaded portion to the neck portion of the container body, and a concave portion 4 is formed in the front surface of the upper part of the peripheral wall thereof, and a short cylinder portion 5 is projected at the center of the concave portion to form a nozzle hole 6. ing. In the illustrated example, the inner cylinder 7 is hung from the rear surface of the top wall 2 in the upper half of the peripheral wall, and the upper part of the peripheral wall and the front part of the inner cylinder are integrally joined in the recessed portion.

An elastic lid plate 8 having an arcuate cross section is fitted in the recess 4 by closing the nozzle hole 6 with a plug portion 9 protruding from the inner surface of the lid plate. The upper edge of the lid plate is connected to the front edge portion of the top wall at the upper end of the recess via the thin hinge portion 10.

The connecting portion is set to have a curvature and a circumferential length in which the elastic lid plate 8 can be elastically inverted above the top wall 3 and turned upside down by rotating the elastic lid plate 8 around the thin hinge portion 10. . When the elastic cover plate 8 is elastically inverted again to be in the upright state, the plug portion 9 closes the nozzle hole 6 again. It should be noted that a recess 11 for hanging a finger may be provided on the peripheral wall portion below the lower end of the elastic lid plate.

In the illustrated example, the upper part of the elastic cover plate 8 on the thin hinge 10 side is formed thin and the lower part is formed thick, and as shown in FIGS. Contrary to the case of hanging, the curved top wall 2 bends along the front edge, whereas the lower part of the lid plate 8 that has moved to the upper side of the cap keeps the curve during hanging as it is as shown in FIG. Is provided.
By forming in this way, it is possible to prevent the lower portion of the lid plate from gradually becoming flat due to elastic fatigue when the elastic lid plate 8 hangs down, but it is not necessary to do so. Alternatively, the same effect can be obtained even if, for example, a material rich in elasticity is selected and the length from the lower end to the upper end of the elastic cover plate 8 is increased.

The cap body and the cover plate described above are integrally formed of a synthetic resin material.

"Effect of the Invention" A recess is provided in the upper part of the front surface of the peripheral wall hanging down from the peripheral edge of the circular top wall, and the elastic cover plate 8 having an arc-shaped cross section is fitted into the recess. Is integrally connected via the thin hinge portion 10, and the connecting portion is pivoted about the thin hinge portion so that the elastic lid plate can be inverted. Since the state can be returned to the upright state and the inverted state and the return to the established state are accompanied by elastic reversal, the elastic cover plate does not rattle, and the nozzle hole provided in the recess is provided. On the other hand, it is possible to ensure the opening and closing by the elastic cover plate. Further, since the cap body and the elastic lid body are integrally molded with a synthetic resin material, the cap can be manufactured at low cost.
