Description

[Detailed explanation of the idea] This case concerns pins and caps.

Conventionally, for the pin and the cap screwed onto the mouth and neck of the bottle, the cross section of the body of the bottle is made non-circular, such as a square shape, and the outer circumferential surface of the cap is formed to have the same shape as that of the bottle. There is one that is made to fit flush with the body.

In this case, various positioning means, engaging means, etc. have been used to tighten the cap so that the direction of the cap matches the direction of the bottle. There were many problems such as deformation of the screw and resulting in stiffness4, easy damage due to excessive force, considerable difficulty in engaging and disengaging, and conversely insufficient action. .

This proposal attempts to solve these conventional problems.

The illustrated embodiment will be described below.

The one shown here is a synthetic resin type bottle with a threaded neck and a 12-karat gold body connected to a body 11 having a rectangular cross-sectional shape and a flat shoulder 13 that can be elastically deformed inward. 1 and
The outer circumferential surface of the outer circumferential wall 21 which is removably screwed onto the neck part 12 of the bottle with the bright part 224 and is provided on the outside of the bright part 22 is flush with the outer circumferential surface of the body part 11 of the bottle 1. The bottle 1 consists of a synthetic resin type cap 2 constructed as shown in FIG. T-The shoulder part 13 on one side is made wide and flat by shifting to one side, and on the upper surface of the shoulder part 13 on the - side, two serrated triangular protrusions 14 and 15 are made in opposite directions to the left and right. The cap 2 is provided integrally with the outer circumferential wall 21 by shifting the bright part 22 to one side in correspondence with the mouth and neck part 12 of the cap 2. The projection 14.
A vertical engagement plate 23 with a cross section that engages with the cap 15 to align the direction of the cap and prevent loosening is provided integrally with the engagement plate 23.

Note that the top wall 24 of the cap 2 is a separate piece 4.
It is attached to the top of the .

In the figure, 25 is a connecting plate.

In addition, in the illustrated example, only the shoulder portion 13 on the negative side is made larger, but the other side may also be made symmetrically larger as shown by the two-dot chain line, and two protrusions 14.15Th are provided on the other side as well. It's fine.

Of course, in this case, the cap 2 is also formed accordingly.

Since it has the above-mentioned configuration, when attaching the cap with 2 gold,
When the bright part 224 of the cap is screwed onto the neck part 12 of the bottle and tightened, the engagement plate 23 will eventually pass over one of the protrusions 15 and engage with the vertical surface of the protrusion 15 to prevent loosening. When the cap hits the vertical surface of the protrusion 14, subsequent forcible tightening of the cap is prevented, and as a result, the orientation of the cap 2 relative to the bottle 1 and the ability to prevent it from loosening are impaired.

The overcoming is achieved by the inward elastic deformation of the bottle shoulder 13, and the engagement plate 23 is moved over one of the protrusions.
By sliding on the inclined surface of No. 5, it can be done extremely smoothly and easily.

Next, when removing the 2-metal cap, when the cap is strongly rotated in the direction of loosening the 2-metal cap, the engagement plate 23 rides over one of the 15-metal protrusions due to the elastic deformation of the bottle shoulder 13, and the engagement is disengaged, allowing it to be unscrewed. .

In this loosening rotation, the vertical surface of the protrusion 15 and the engagement plate 2
In order to make the sound of engagement and disengagement with 3, a stronger force is required at once than when tightening, but since this force causes the sound of elastic deformation in the bottle shoulder 13, a particularly large force is not required. In addition, on the other hand, it works extremely well to prevent the cap 2 from loosening.

According to the present invention, when the cap 2 is tightened, the shoulder portion 11 of the bottle 1 is elastically deformed inward, and one of the protrusions 15, which the engagement plate 23 overcomes, has a sloped metal surface, so that the cap 2 can be tightened smoothly. The orientation of the cap 2 can be easily aligned and the locking engagement can be easily performed. At this time, the engagement plate 23 has a top-shaped cross section and is difficult to deform in the front-rear direction, while the bottle shoulder 11 is bent inward and vertically The engagement plate 23 and the protrusions 14, 15 are elastically deformed.
In the engagement with the cap, there is no back-and-forth movement once the cap is operated, and one protrusion 15 that can be climbed over the engagement plate 23 and the other protrusion 14 that abuts the engagement plate 23.
and 4. Since the positioning metal fittings are arranged on the left and right, one protrusion 15
Even if the shoulder portion 13 is largely elastically deformed and the protrusion 15 sinks significantly in the position shown in FIG. There is no deformation and there is no hesitation in the spiral movement.

Since the loosening is prevented by the engagement between the vertical surface of one of the protrusions 15 and the vertical engagement plate 23, the loosening can be sufficiently prevented.

When removing the cap, due to this kind of engagement, a certain amount of strong force is temporarily required to disengage the metal and close the cap.
There is no inconvenience such as damage caused by excessive elastic deformation of the cap, and even if a certain amount of force is temporarily required when tightening the cap, the engagement plate at the top of the hanging protrusion 15 will close as soon as the engagement is released. At the same time as the cap 23 gets over the bottle shoulder 11, the elastic deformation of the bottle shoulder 11 acts to loosen the cap 2, and the cap 2 is loosened.

It is simple in structure and manufacture and can be provided at low cost, making it extremely useful in practice.
