Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cap for dispensing or dispensing liquid such as lotion, for example.

``Prior art'' As this kind of cap, for example,
The invention disclosed in Publication No. 34614 is known. The cap has a peripheral wall for fitting the container body hanging from the peripheral wall of the top wall with a through hole, a recess is formed in the top wall portion behind the through hole, and a shaft hole is formed at both left and right ends of the recess. a main body, a lid body having a shaft attached to the rear lower surface of the lid plate placed on the top surface of the top wall with the through hole closed, and both ends of the shaft rotatably fitted into the shaft hole; A protrusion is attached to the middle part in the left-right direction of the bottom surface of the recess, and an arc-shaped groove is provided on the outer surface of the shaft, into which the protrusion is slidably fitted and press-contacted when the lid body is rotated about the shaft. This is a hole drilled into the part.

``Problem to be solved by the invention'' In the conventional cap described above, the protrusion attached to the bottom of the concave portion of the cap body is provided so that it slides relative to the inside of the arc-shaped concave groove while rubbing against it. There was a drawback that the friction parts were prone to friction and rattling.

In this case, the small protrusion as the protrusion is attached to the shaft side, and the shaft portion to which the small protrusion is attached is made into an elastically deformable cylindrical shape, so that the small protrusion is attached to the inner wall surface of the shaft hole. The elastic pressure contact reduces the wear of the small protrusions caused by the rotation of the lid, and a small recess is provided on the inner wall surface of the shaft hole so that the small protrusions enter into the small recess when the lid is opened and closed, and the lid is closed. It is designed to maintain the open/closed state of the lid.

"Means for Solving the Problems" A peripheral wall 4 is hung from the periphery of the first top wall 3 with a through hole 2, and a recess 5 is formed at an arbitrarily determined rear edge of the upper end of the peripheral wall, and the recess is Synthetic resin cap body 1 with shaft holes 6, 6 formed on both left and right sides
and a second top wall 9 placed on the upper surface of the first top wall with the through hole closed, and a shaft head 10 protruding from the rear part of the second top wall is placed in the recess 5, and Elastically deformable cylindrical shafts 11, 11 protruding from the upper portions of both left and right sides of the shaft head via connecting portions 13 are inserted into the shaft hole,
A cylindrical shaft consisting of a synthetic resin lid 8 fitted with each other, small recesses 7, 7 formed at intervals in the circumferential direction of the inner circumferential wall of the shaft hole, and spaced apart from the connecting portion in the outer circumferential direction of the shaft. A small protrusion 12 fitted inside one of the small recesses is provided on the outer surface portion, and the cylindrical shaft rotates while the small protrusion 12 is in elastic pressure contact with the inner circumferential wall surface of the shaft hole during opening and closing of the lid. The small projection fits into the small recess when the body is opened and closed.

"Operation" Since the small protrusion 12 fits into the small recess when the lid is open or closed, the lid does not move blindly with respect to the cap body, and if the lid is released midway through rotation, the small protrusion 12 will fit into the small recess. is in pressure contact with the inner circumferential wall surface of the shaft hole, and the cylindrical shafts 11, 11 are elastically deformed into an elliptical shape, so the lid body stops while maintaining its release angle.

``Embodiment'' The cap of the present invention consists of a cap body and a lid pivotally attached to the cap body.

The cap body 1 has a peripheral wall 4 hanging from the periphery of a first top wall 3 with a through hole 2, a recess 5 formed at an arbitrarily determined rear edge of the upper end of the peripheral wall, and a recess 5 on both left and right sides of the recess. Shaft holes 6, 6 are formed. Small recesses 7, 7 are bored in the opposing surfaces of the inner circumferential wall of the shaft hole. The cap body is integrally molded from synthetic resin.

The lid body 8 is also integrally molded from a synthetic resin material, and has a second top wall 9 that closes the above-mentioned through hole and is placed on the upper surface of the first top wall. 10
, and elastically deformable cylindrical shafts 11, 11 are projected from both left and right sides of the shaft head. Shaft head 10
is fitted into the recess of the cap body, and the cylindrical shaft is fitted into the shaft hole. A small protrusion 12 is attached to the outer surface of the cylindrical shaft, and the small protrusion is provided to fit into the small recesses 7 when the lid is opened and closed.
During the opening/closing of the lid, the cylindrical shafts 11, 11 are elastically deformed into an elliptical shape, so that the small protrusion rotates while remaining in elastic pressure contact with the peripheral wall surface of the shaft hole.

The shaft head 10 and the cylindrical shafts 11, 11 are connected only at the upper part 13 of the base end of the cylindrical shaft so that the cylindrical shaft can easily be elastically deformed, and the other parts are separated 14, 14. In addition, so that the cylindrical shaft can be easily fitted into the shaft hole,
A notch 15 narrower than the shaft diameter is provided above the shaft hole, and the cylindrical shaft can be fitted into the shaft hole through the notch by elastic deformation of the cylindrical shaft and the bearing. The lid is provided so that when the lid is closed, the small protrusion 12 is pressed against the lower surface of the small recess on the open side of the lid by the restoring force of the cylindrical shaft, and the second top wall is pressed against the first top wall. . Therefore, as shown in Fig. 3, a small recess 7, which is provided almost on the horizontal diameter line of the shaft hole
7, the small protrusion 12 is attached to the rear surface slightly below the horizontal diameter line of the shaft portion. When the lid body is lowered from the state shown in FIG. 3 and the cylindrical shaft is fitted into the shaft hole, the small protrusion is located on the lower surface of the open side of the lid body in the small recess, as shown by the two-dot chain line in FIG. 6b would be a hindrance and would prevent them from fitting, but by forced fitting, the cylinder is elastically deformed into an elliptical shape and fitted as shown in FIG. 4. Due to the elastic deformation, the small projection comes into pressure contact with the side surface and urges the lid in the closing direction, so that the second top wall of the lid comes into pressure contact with the first top wall of the cap body. By doing so, it is possible to ensure that the second top wall closes the through hole.

"Effect of the invention" Small recesses 7, 7 are provided on opposing surfaces of the inner circumferential wall of the shaft hole, and a small protrusion 12 is provided on a part of the outer surface of the cylindrical shaft, so that the small protrusion fits into the small recess when the lid is opened and closed. Since the lid is designed to fit, the closed state of the lid is maintained and the lid does not open unnecessarily, and the lid is kept open so that the lid does not move blindly when dispensing or shaking out the contents stored in the container. There is no problem, and since the small protrusion is provided so as to come into elastic pressure contact with the inner circumferential wall surface of the shaft hole during opening and closing of the lid, any opening angle of the lid can be maintained.

Also, cylindrical shafts 11, 11 fitted into the shaft holes 6, 6
, only the upper portions 13, 13 of the base end are connected to the shaft head end surface, and the lower parts are separated 14, 14, and the small protrusions 12, 12 are separated from the connecting portion 13 between the shaft head end surface and the base end of the cylindrical shaft. Since the small projections 12, 12 are attached to the outer surface portions of the cylindrical shaft separated in the direction of the outer circumference of the shaft,
When the cylindrical shaft comes into pressure contact with the inner wall surface of the shaft hole, the cylindrical shaft is elastically deformed into an elliptical shape due to the reaction force, and the small protrusion is pressed against the inner wall surface of the shaft hole with a moderate force due to the elastic restoration of the cylindrical shaft. This results in sliding movement, thereby reducing wear at the pressure-welded parts.
