2. Description of the Related Art As a cap, for example, a cap having a top wall that closes an upper end opening of a mouth and neck portion extending from an upper edge of a peripheral wall screwed around an outer periphery of the mouth and neck portion of a container body is generally known.

In dispensing the liquid, the cap is screwed out of the container body, and the stored liquid is discharged while being held in the hand or on the side, and then screwed again. Therefore, handling when unscrewed is inconvenient.

In consideration of such a point, a ring fitted to the lower part of the mouth and neck portion of the container body in such a manner that the ring is prevented from coming off, and a ring that is rotatable around the lower peripheral part of the peripheral wall of the above-mentioned conventional cap and is prevented from coming out. A ring to which a fitted ring is attached, which is integrally connected to a fitted ring by a flexible band, is used.

[0005]

In the case where the connecting member is mounted, when the cap is unscrewed, the cap can be held on the side of the mouth and neck of the container by the connecting member. There is. However, in a state in which the cap is screwed, the belt-like portion connecting the rings protrudes in a horizontal U-shape and becomes a hindrance, and there is a possibility that inconveniences such as dropping the container by hooking thereat may occur.

[0006] In view of the above, the present invention can be held on the side of the mouth and neck when the cap is unscrewed when using the attached container, and when the cap is screwed when not in use. It is an object of the present invention to provide an excellent cap having almost no extra protruding portion and having no risk of inconvenience, such as catching and knocking down a container.

[0007]

According to a first aspect of the present invention, there is provided a cap, wherein a ring is provided at a lower portion of an outer periphery of a mouth and neck portion of a container body so as to prevent upward escape and rotate. A support member A having a connecting plate 4 formed integrally with the connecting plate 4 and having a vertically long guide cutting groove a formed in the connecting plate 4 so as to be able to be raised and lowered immediately before the ring; The top wall 10 is extended from the upper edge of the peripheral wall 9 screwed to the outer periphery of the upper part 2 of the container body, and the engaging projection 11 projecting from the lower part of the outer surface of the peripheral wall 9 can be lifted up and out of the lower end of the guide groove. And a cap body B which is fitted so that it is impossible to fit, and after the cap body is unscrewed, the cap is configured to be supported by the connecting plate to the side of the mouth and neck, thereby forming a cap.

In the cap according to the second aspect of the present invention, the connecting plate 4 connects the base ends to both sides of the outer surface of the ring 3 so as to extend in a semicircular shape just before the ring, and the front end portion is tangential to the ring. The cap according to claim 1 is a connecting plate 4 protruding from a front edge of the elastic substrate 6 configured to be able to undulate by a transverse thin hinge b.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

[0010] As shown in the drawings, the cap 1 of the present invention comprises:
A support member A and a cap body B are provided.

The support member A is made of a synthetic resin. A ring 3 is rotatably fitted to the lower part of the outer periphery of the mouth and neck portion 2 of the container body C to prevent it from coming out upward and to be rotatable. A connecting plate 4 that is erected upright immediately before is integrally formed, and a vertically long guide cutting groove a is formed in the connecting plate 4.

As shown in FIG. 2, the support member A of this embodiment has a number of rectangular plate-like projections 5 projecting from the lower end of the inner surface of the short cylindrical ring 3 in the circumferential direction. In addition, an elastic substrate 6 is provided on both outer surfaces of the ring 3, the base ends of which are connected to each other so as to extend in a semicircle just before the ring, and the front end of the ring 3 can be raised and lowered by a thin hinge b crossing the ring tangentially. An elongated connecting plate 4 protrudes in the front-rear direction from the front of the center of the front surface of the elastic substrate, runs back and forth in the center of the connecting plate, and has a guide groove a formed with a semicircular front and rear end. .

The connecting plate is not limited to being provided via the elastic substrate described above, but may be erected upward from the outer surface of the ring via a thin hinge directly so as to be able to undulate. However, the structure in which the connecting plate is provided via the elastic substrate has an advantage that even if the connecting plate is slightly shorter, the connecting plate can be elastically deformed to compensate for it.

A locking plate 7 protrudes from the lower rear end of the center of the outer surface of the ring 3 via a thin hinge c so as to be able to undulate. A notch d having a U-shape in a plan view is formed at the tip of the locking plate 7.

The support member A having such a structure can be prevented from slipping out by getting over the locking ridges 8 provided on the lower part of the outer periphery of the mouth and neck portion 2 of the container body and engaging the projections 5 on its lower surface. It is fitted rotatably.

The cap body B is also made of synthetic resin, and has a top wall 10 extending from an upper end edge of a peripheral wall 9 screwed to the outer periphery of the container body neck portion 2 above the ring.
An engagement projection 11 protruding from a lower portion of the outer surface is fitted to a lower end of the guide groove a so as to be liftable and unable to come out.

In this embodiment, a large-diameter locking projection 11 is provided at the tip end.
a is formed at the front lower portion of the outer surface of the peripheral wall 9, and the engaging protrusion 11a is forcibly inserted into the guide groove a.
Is fitted. A second engaging projection 12 having a large-diameter locking projection 12a formed at the distal end thereof is formed at the lower end of the outer surface of the peripheral wall 9 in the same manner as the engaging projection 11. To
The engaging plate 7 is engaged with the cutout portion d of the locking plate 7 that has been raised. The engagement of the second engagement projections 12 facilitates the rotation of the ring at the start of unthreading, and reduces the load on the thin hinge b.

In the cap 1 constructed as described above, when the cap body B is screwed up from the state shown in FIG. 1, the ring 3 is rotated together with the cap body B, and the engaging projection 11 is moved into the guide groove a. To rise. If the cap body B is turned outwardly when the cap body B is completely unscrewed, the connecting plate 4 is turned outwardly around the thin hinge b and the cap body B is moved to the side of the mouth and neck 2. Can be held.

Further, after use, the connecting plate is raised to move the cap body above the mouth and neck, and then the cap body is screwed.
Descends along the guide groove a and returns to the original state.

[0020]

As described above, the cap of the present invention prevents the upper part from slipping out and fits the ring 3 rotatably at the lower part of the outer periphery of the mouth and neck portion 2 of the container body. A support member A having a vertically extending guide cutting groove a formed integrally with a connecting plate 4 which is erected and erected and screwed onto the outer periphery of the container body neck portion 2 above the ring. While extending the top wall 10 from the upper edge of the peripheral wall 9 that has been made,
And a cap body B in which an engagement protrusion 11 protruding from a lower part of the outer surface of the peripheral wall 9 is fitted to a lower end of the guide groove so as to be liftable and unable to come out. After the cap body is screwed off, the cap body is connected with the connecting plate. Since it is configured to support the side of the mouth and neck, it is not necessary to take out the stored items while holding the removed cap in hand, and it is troublesome to place the cap or lose the placed cap etc. Does not occur. Further, unlike the conventional product, there is no large protruding portion, and there is no inconvenience that the protruding portion is hooked and the container is knocked down. In addition, the connecting plate 4 connects the base end to both sides of the outer surface of the ring 3 and wraps around the ring in a semi-circular shape just before the ring, and crosses the front end tangentially of the ring.
In the case where the connecting plate 4 is formed so as to protrude from the front edge of the elastic substrate 6 which is configured to be able to be raised and lowered, a dimensional error occurs in the connecting plate and the guide groove, and the cap body is unscrewed before being unscrewed. Even if the engaging protrusion reaches the highest position of the guide groove, the elastic substrate can be slightly elastically deformed in the vertical direction, so that the elastic substrate can be easily unscrewed. This also allows the connecting plate to be made shorter and more compact.
