JPS582765Y2 - irregularly shaped container - Google Patents

Description

[Detailed description of the invention] The present invention forms an inner ratchet on the cylindrical outer circumferential surface of an inner cap that is screwed onto a container mouth having a bow on its outer periphery, and rotates the inner cap in a direction to remove it from the container mouth. At this time, an outer ratchet that engages with the inner ratchets 1 to 1 is formed on the inner circumferential surface of the cylindrical recess, and a square or oval outer cap having a transverse outer shape that is equal to the transverse outer diameter of the container body is attached to the inner cap. A protrusion is provided on the upper surface of the shoulder, a hanging portion is provided on the lower peripheral edge of the outer cap to cover the container shoulder, and a protrusion is provided on the lower end surface of the outer cap inside the hanging portion. This relates to an irregularly shaped container in which the protrusion and the protrusion are brought into contact with each other to align the container body and the outer cap. It is applied to irregularly shaped containers, and allows the cap attached to the container body to be easily aligned with the container body.

Conventionally, methods for aligning the container body and cap of irregularly shaped containers such as polygons and ellipses include the lug cap method, in which a steep slope is provided and the lower end of the cap is forcibly fixed on the shoulder of the container body, or the lower part of the cap. In this method, a convex part is provided on the container body, and it is stopped by contact with a convex part provided on the shoulder of the container body.Furthermore, after the inner cap is screw-fitted to the container mouth part, the outer cap is adjusted to match the shape of the container body. A method of fitting the inner cap is generally provided.

These caps are often double-layered due to their design or molding.

In the first two methods, when fitting the inner and outer caps together, it is necessary to align the caps with each other (especially important in an asymmetric type), resulting in extremely low productivity.

In addition, the latter method also had many drawbacks such as poor assembly productivity because the inner cap was fitted and then the outer cap was fitted while aligning. The present invention is free from these drawbacks.

An embodiment of the present invention will be described below with reference to the drawings. An inner ratchet 4 is formed on the cylindrical outer peripheral surface of an inner cap 3 that is screwed onto a container mouth 2 having a thread 1 on the outer periphery. An outer ratchet 5 is formed on the inner circumferential surface of the cylindrical recess, which engages with an inner ratchet 4 when the inner cap 3 is rotated in the direction of removal from the container opening 2, and idles when the inner cap 3 is completely retracted into the container mouth 2. A rectangular or oval outer cap 6 having a shape equal to the transverse outer diameter of the container body 13 is attached to the inner cap 3 to form a cap 7 integrally. Container shoulder 8 on the lower periphery
A hanging portion 10 is provided protrudingly covering the outer cap 6, and a protrusion 12 is provided protrudingly on the lower end surface 11 of the outer cap 6 inside the hanging portion 10.
When the protrusion 9 and the protrusion 12 come into contact with each other, the container body 13 and the outer cap 6 can be aligned.

When inserting the cap 7 into the container opening 2, insert the inner cap 3.
The contact resistance between the inner ratchet 4 and the outer ratchet 5 of the outer cap 6 causes them to move together, but even if the inner cap 3 is screwed into the container mouth 2 and stops rotating, the outer cap 6
further rotates until the protrusion 12 comes into contact with the protrusion 9, and when it stops, the alignment of the outer cap 6 and the container body 12 is completed.

In the present invention configured as described above, the cap 7, which has the outer cap 6 attached to the inner cap 3, is screwed onto the container opening 2, and the protrusions 9 and 12 come into contact with each other, and the rotation of the cap 7 is stopped. When the outer cap 6 and the container body 13 are aligned, when the cap 7 is removed from the container opening 2,
Since the inner ratchet 4 of the inner cap 3 and the outer ratchet 5 of the outer cap 6 are engaged, the inner cap 3 and the outer cap 6 move together and are screwed off from the container opening 2 as one. It is something that can be done.

When unscrewing the cap 7, the projections 9 and 1
The pitch of the threads 1 of the container opening 2 and the threads of the inner cap 3 that are screwed together with the threads 1 is set so that the threads 2 and 2 do not come into contact with each other.

In the present invention, an inner ratchet 4 is formed on the cylindrical outer peripheral surface of an inner cap 3 that is screwed onto a container opening 2 having a thread 1 on the outer periphery.
When the inner cap 3 is rotated in a direction to remove it from the container mouth 2, the outer ratchet 5 that engages with the inner ratchet 4 is formed on the inner circumferential surface of the cylindrical recess.
A square or oval outer cap 6 equal to the transverse outline of
is attached to the inner cap 3, a protrusion 9 is provided protruding from the upper surface of the container shoulder 8, and a hanging portion 10 is provided protruding from the lower peripheral edge of the outer cap 6 to cover the container shoulder 8. Hanging part 1
A protrusion 12 is provided protrudingly on the lower end surface 11 of the outer cap 6 inside the container 0, and the protrusion 9 and the protrusion 12 are brought into contact with each other to align the container body 13 and the outer cap 6. Therefore, if the outer cap 6 is attached to the inner cap 3 and the cap 7 is screwed onto the container opening 2 until it cannot be rotated without considering the attachment position, the outer cap 6 and the container body 13 will be in the same position. It can be easily and reliably matched,
Further, when the outer cap 6 is attached to the container body 13, the hanging portion 10 on the lower peripheral edge of the outer cap 6 covers the container shoulder portion 8, so that when the outer cap 6 is attached to the container body 13, the protrusion 9 of the container shoulder portion 8 is covered and the protrusion 9 is inserted from the outside. It cannot be seen and does not detract from the beauty of the container.
