Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a cap structure that produces sound, and more specifically, the invention relates to a cap structure that produces sound. This concerns the cap structure that occurs.

《Description of the Prior Art》 Conventionally, when a cap is screwed onto a container and tightened, small protrusions are formed on the circumferential surfaces of each of the cap and the container in order to position the cap, so that one of them rides over the other. This method is known (for example, Japanese Utility Model Publication No. 44452/1983).

In this known cap structure, a slight clicking sound may be generated when one small protrusion climbs over the other small protrusion. However, since this cap structure was originally intended for positioning the cap and not for notifying the tightening of the cap by generating a sound, a special device was devised to generate a relatively loud sound. has not been done.

<<Purpose of the invention>> The present invention has been made to meet the diverse preferences of recent consumers, and its object is to provide a cap structure that generates a relatively loud sound when the cap is tightened and untightened.

<Means for Solving the Problems> According to the cap structure that produces sound according to the invention of the present application, there is an inner cap that is screwed onto a thread formed on the outer periphery of the open end of the container, and an outer cap that is connected to the outer surface of the inner cap. It consists of an outer cap that is loosely fitted. A relatively wide space is formed between the lower surface of the ceiling of the inner cap and the lower surface of the ceiling of the outer cap, and a projection is provided on one side of the upper surface of the ceiling and a flexible protrusion on the other side. The protrusions are provided so that they can be contacted, and the flexible protrusions are formed so as to generate a sound when they get over the protrusions. Further, when tightening the inner cap and the outer cap to the threaded portion, the outer cap engages with the inner cap after the flexible protrusion passes over the protrusion in the tightening direction.
and a second engaging portion where the outer cap engages with the inner cap after the flexible protrusion passes over the protrusion in the direction of loosening it when the screwing is released.

<<Example>> Reference numeral 1 indicates a container body, and a thread 3 is integrally formed on the outer periphery of the neck 2 of the container body, and an inner plug 4 having relatively elasticity is detached from the upper end thereof. Impossibly attached.

The cap 5 of the present invention consists of an inner cap 6 and an outer cap 7, and the inner cap 6 has a thread 3 on the neck 2.
The outer cap 7 is sufficiently higher than the inner cap 6 and is loosely fitted to the outside of the inner cap. That is, the inner cap 6 has an annular groove 9 on its lower outer periphery, and an annular projection 10 is formed in the annular groove 9 on the lower inner periphery of the outer cap 7.
By rotatably fitting the inner and outer caps 6 and 7, the inner and outer caps 6, 7 are irreparably connected. In addition, a spherical protrusion 12 is provided at the center of the lower surface of the ceiling portion 11 of the inner cap 6, and an annular wall surface 13 is provided on the outer periphery of the protrusion 12.
is formed, and the inner cap 6 is attached to the neck 2 of the container body 1.
When tightened, the spherical protrusion 12 comes into close contact with the central opening of the inner plug 4, and the annular wall surface 13 is pressed against the upper peripheral surface of the inner plug 4.

According to the present invention, the ceiling portion 11 of the inner cap 6
A protrusion 14 is formed on the upper surface along the radial direction at an intermediate position between the center and the outer periphery, and a relatively wide protrusion 14 is formed on the upper peripheral wall of the inner cap 6 along the circumferential direction around the extension of the protrusion 14. Concave groove 15 extending to
is formed. Both side wall portions of this groove 15 serve as first and second engaging portions. moreover,
The ceiling portion 1 of the outer cap 7 corresponds to the projection 14.
A flexible projecting piece 17 is integrally formed to hang down from the lower surface of the outer cap 7, and a protrusion 18 is formed on the inner circumferential surface of the outer cap 7 in correspondence with the groove 15.
It's now within 5. The flexible projecting piece 17 is configured such that its lower end side can come into contact with the upper side of the projection 14 .

Now, when the cap 5 is started to be screwed onto the neck 2 of the container body 1, as shown in FIG. The inner cap and the outer cap continue to be screwed together in this state by coming into contact with the side of the protrusion 14. A spherical protrusion 12 and an annular wall surface 13 are formed on the lower surface of the ceiling portion 11 of the inner cap 6.
When the inner cap 4 comes into contact with the inner cap 4, resistance to the lowering of the inner cap 6 occurs. If the cap 5 is further tightened at this point, the resistance to the lowering of the inner cap 6 will increase, and the outer cap 7 will close to the inner cap 6.
The flexible protrusion 17 of the outer cap 7 climbs over the protrusion 14 of the inner cap 6 and assumes the position shown in FIG. 2. At this time, as shown in FIG. 2C, the flexible protrusion 17 suddenly assumes the position indicated by the solid line after being bent by the protrusion 14, so a relatively loud "pop" sound is heard. occurs.
At this time, the flexible projecting piece was bent to generate sound in a relatively wide space formed between the upper surface of the ceiling of the inner cap and the lower surface of the ceiling of the outer cap, so that it was almost sealed. As the sound reverberates in the space where it is created, the sound is amplified and becomes louder.

Thereafter, the convex portion 18 on the side wall of the outer cap 7 comes into contact with the rotational direction side wall portion (first engagement portion) of the groove 15 of the inner cap 6, so when the cap 5 is further tightened to the container body 1, The spherical protrusion 12 and annular wall surface 13 of the inner cap 6 partially bite into the central opening and upper surface of the inner plug 4, completely sealing the opening of the container body.

Next, when loosening the cap 5, the inner plug 4 is
Since the tight engagement between the inner cap 6 and the inner cap 6 is relatively strong,
First, the outer cap 7 starts rotating relative to the inner cap 6, and the flexible protrusion 17 of the outer cap 7 climbs over the protrusion 14 of the inner cap 6 in the opposite direction to that shown in FIG. A relatively loud "pop" sound is generated. Thereafter, the protrusion 18 on the side wall of the outer cap 7 is connected to the groove 15 of the inner cap 6.
Since the outer cap 7 and the inner cap 6 come into contact with the wall portion (second engaging portion) on the side opposite to the side shown in FIG. It becomes possible to take it out.

It should be noted that the present invention can be modified in various ways other than the above embodiment, and FIG. 3 shows another embodiment of the present invention, in which the ceiling part 16 of the outer cap 7 is

b through an adhesive or the like. By using such a metal piece 17a, a metallic sound can be emitted when the cap 5 is opened or closed. Furthermore, in this embodiment, the inner cap 4 is vertically movably engaged with the upper end opening of the neck 2 of the container body 1 via an O-ring 19, and this O-ring 19 is used as a resistor against the lowering of the inner cap 6. ing. Furthermore, or
An alignment protrusion 20 is formed at the base of the neck 2 of the container body 1, and an engagement piece 21 that can be engaged with the protrusion 20 is formed at the lower end of the inner cap 6.
At the final tightening position, the engagement piece 21 comes into contact with the alignment protrusion 20, so that the cap 5 is correctly aligned with the container body 1. Although this alignment mechanism can be applied to cylindrical container bodies and caps, it is particularly preferable when these have polygonal planar shapes.

In addition, in the above-mentioned embodiment of the present invention, the flexible protrusion was formed or attached to the outer cap, and the opposing protrusion was formed on the inner cap, but it will be explained in detail that these positional relationships can be reversed. Not even.

<<Effects>> As described above, in the cap structure of the present invention, the flexible projecting piece can be bent within the relatively wide space formed between the upper surface of the ceiling of the inner cap and the lower surface of the ceiling of the outer cap. Since the sound is generated, the sound is reverberated in a substantially closed space, so the sound is amplified and becomes louder, so that the user can be clearly informed of the end and start of tightening the cap.
