JPS5837807Y2 - Bottle mouth and cap - Google Patents

Description

[Detailed explanation of the idea] This proposal concerns the mouth and cap of the bottle.

Bottles with caps that have screwed caps on the mouth are generally
The bottle is made of glass or synthetic resin, and the cap is made of synthetic resin or metal.

By the way, due to the material of this type of bottle, the cap may come loose when vibration is applied during transportation, for example.

This is especially severe in glass bottles.

The present invention attempts to eliminate such conventional drawbacks.

The illustrated embodiment will be described below.

In the figure, 1 is a glass bottle, and 2 is a synthetic resin cap that is removably screwed onto the neck 11 of the glass bottle.

In the glass bottle 1, the outer peripheral edge of the mouth portion 12 is cut out, and a plurality of protrusions 13 are formed and arranged in the remaining portion.

The cap 2 includes a cap body 21 that is screwed onto the neck portion 11 of the glass bottle 1, and an interior member 2 that is provided inside the cap body 21.
Consists of 2.

The cap main body 21 is formed to be tall, and has a threaded part 23 in the lower half of its interior, and a threaded thread 26 that threads with the thread 14 of the bottle neck part 11 on the lower half of the peripheral wall. A plurality of vertical protrusions 27 are formed on the inner surface of the upper half of the peripheral wall, with the upper half being a vacant chamber 24.
... and one circumferential horizontal protrusion 28 are provided on the upper and lower sides.

The interior member 22 is made of a moderately elastic material,
A fitting tube 29 is provided on the inner surface of the upper half of the circumferential wall 25 of the cap body 1 to fit into the empty chamber 24, and the fitting tube 29 is provided on the outer peripheral surface of the cap body 1 in the vertical direction. Projection 2
7... Forms a vertical knurl 30 that is non-rotatably engaged, and also forms engaging transverse protrusions 31, 31 that irremovably engage with the transverse protrusions 28 of the cap body 1. There is.

Further, a closing plate 32 is integrally installed horizontally at the lower end of the fitting tube 29, and the closing plate 32 is pressed into contact with the inner and outer peripheries of the bottle opening 12 at appropriate intervals in a double-sided manner at the lower peripheral edge of the closing plate 32. 2
33 and 34 are integrally hung down, and the outer skirt 34 is cut out from below at regular intervals to form a large number of tongue pieces 35 arranged around the circumference in a row. A protrusion 36 for watertight contact is provided around the top surface of the bottle opening 12 between 33 and 34.

Note that 37 in the interior member 22 is a reinforcing piece.

The inner skirt 33 is curved inward, and the outer skirt I, 34, and therefore the tongues 35 are curved outward.

The cap main body 21 and the interior member 22 described above are each integrally molded as a whole, and are integrally fitted together.

When the cap 2 is screwed onto the bottle opening 11, the inner skirt 33 of the interior member 22 is attached to the inner edge of the bottle opening 12.
Further, the protrusion 36 between both skirts 1-33, 34 is pressed against the top surface of the bottle mouth 12, and the bottle mouth 12 is closed watertight, and the outer skirt 34 and the numerous tongue pieces 35...
...is a plurality of protrusions 13 on the outer edge of the bottle mouth 12...
..., and the cap 2 is prevented from loosening by this engagement.

When removing the cap 2, it is only necessary to forcibly unscrew it.

According to the present invention, when the cap 2 is screwed onto the bottle opening 12, the tongue pieces 35 on the interior member 22 are replaced by the protrusions 13 on the outer peripheral edge of the bottle opening 12. The cap 2 is firmly prevented from loosening by elastically engaging with the cap 2, thereby preventing loosening due to vibration caused by the material of the bottle (during transportation, etc.).
In particular, it can prevent severe loosening of glass bottles.

Furthermore, when the tongue pieces 35 are elastically engaged with the projections 13, only the tongue pieces 35 are elastically deformed, and the interior member 22 No elastic deformation is applied to the closing plate 32 and the inner skirt 33 of the bottle opening 12.
The closing plate 32 and the inner skirt 33 allow the tongue pieces 35 to be elastically engaged with each other to ensure hot closure without any trouble.

Further, large dimensional tolerances for each part can be tolerated.

It is simple in structure and production, and has similar practical benefits to sumo wrestling.
