Description

[Detailed Description of the Invention] The present invention relates to a shoulder attachment structure for a magic bottle having a body made of a blow-molded product.

BACKGROUND ART Conventionally, as shown in FIG. 1, a charm bottle has been provided which uses a body 1 made of a blow-molded product and covers the body with an exterior 2 made of rattan or the like.

In this kind of magic bottle, the inner flange 3 provided at the upper end of the body 1 is sandwiched between the lower surface of the shoulder body 4 and the upper surface of the shoulder body mounting nut 6 screwed onto the bottle mouth holder 5 of the shoulder body 4. By doing this, the fuselage 1
and the shoulder body 4 were connected and fixed.

In this case, if the Okibin 8 is tightened with the tightening body 7 during assembly,
The tightening force is concentrated on the inner collar 3 via the bottle mouth holder 5 of the shoulder body 4 and the shoulder body mounting nut 6.

However, since the body 1 is a blow-molded product, it is soft and easily deforms, and when the inner bottle 8 is tightened as described above, the inner flange 3 bends upward as shown in Figure 2, and the tightening force gradually decreases. This has disadvantages in that it causes water leakage, and a gap occurs at the joint between the body 1 and the shoulder body 4, resulting in an unsightly appearance.

This invention was created in view of the above-mentioned drawbacks, and it is a magic gift that does not deform the body made of blow molded product when the inner bottle is tightened, completely preventing water leakage and the occurrence of gaps. The purpose of the present invention is to provide a shoulder body mounting structure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

Figure 3 shows an example of the magic bottle according to the present invention, with 10
19 is a medium bottle made of a vacuum-made double bottle housed inside the body 10; 20 is a body 10 made of a blow-molded product;
21 is a fastening body screwed onto the bottom body 20; 22 is a shoulder body placed on the upper end of the body 10; 29
30 is an eyebrow cover attached to the upper end of the shoulder body 22, and 31 is a shoulder body attachment nut for attaching the shoulder body 22 to the body 10.

The body 10 is integrally provided with a handle 11 as shown in FIG. Its upper and lower ends are regulated in position by outer flanges 13 and 14.

The upper part of the body 10 is formed with an inclined part 15 that gradually increases in diameter toward the bottom, and the upper end of the body 10 is provided with an inner flange 16 around the entire circumference. is provided with one notch 17 and two protrusions 18.

The shoulder body 22 is formed into a double structure of an inner cylinder 23 and an outer cylinder 24 as shown in FIGS. 5 and 6, and has a sprue part 25 on the side.
is installed protrudingly.

At the lower end of the inner cylinder 23 is formed a bottle spout holder 26 having a male screw on the outer periphery, and on the lower surface of the sprue 25 a protrusion 27 is provided.

Six supporting pieces 28 are radially protruded from the outer circumferential surface of the inner cylinder 23 so as to have a certain gap between them and the inner circumferential surface of the outer cylinder 24. It is located above the lower end of the tube 24 by at least the thick bone of the outer flange 13 of the body 10.

Two of the support pieces 28, 28a, engage with the protrusion 18 on the upper surface of the body 1 to prevent rotation, while the protrusion 27 engages with the notch 17 provided in the inner flange 16 of the body 10. The positional relationship between the shoulder body 22 and the body 10 is determined.

As shown in FIG. 7, the shoulder body mounting nut 31 has an outer surface that is tapered approximately in the same shape as the inner surface of the inclined portion 15 of the body 10, and the upper end inner surface of the nut 31 is provided with a bottle opening receiving portion of the shoulder body 22. A female screw 32 is provided which is screwed into the outer periphery of 26.

Note that 33 and 34 are reinforcing ribs.

Next, the method of assembling the magic bottle having the above structure will be explained. First, the shoulder body 22 is placed on the upper end of the body 10 covered with the outer device 2, and the convex part 27 and the notch 17 are fitted together. The shoulder body 22 is positioned with respect to the body 10 by the engagement of the support pieces 28 a , 28 a and the protrusion 18 .

In this state, when the shoulder body attachment nut 31 is screwed into the bottle mouth holder 26 of the shoulder body 22 from inside the body 10, the outer surface of the shoulder body attachment nut 31 is pressed against the inner surface of the inclined part 15 of the body 10, and one side The support piece 28 of the shoulder body 22 is pressed onto the upper surface of the inner collar 16, and the body 10, the shoulder body 22, and the shoulder body attachment nut 31 are integrated.

Next, the medium bottle 19 is housed from below the body 10, the bottom body 20 is fixed to the lower end of the body 10, and the medium bottle 19 is tightened by the linear body 21, so that the bottle mouth of the medium bottle 19 is attached to the mouth rubber 3.
5 to the bottle mouth holder 26 of the shoulder body 22, and the medium bottle 19
is fixedly supported.

Thereafter, the plug body 29 is attached to the shoulder body 22 to complete the assembly.

When the medium bottle 19 is tightened, the tightening force acts on the body 10 via the bottle mouth holder 26 of the shoulder body 22 and the shoulder body attachment nut 31, but the shoulder body attachment nut 31 is attached to the body with its outer surface. 10 is crimped onto the inner surface of the sloped part 15 of the body 10, and the upper blades of the middle bottle line are distributed over the entire sloped part 15 of the body 10, so there is no need to worry about the tightening force concentrating on the inner flange and causing the inner flange to bend, unlike in the past. .

In particular, since the inclined portion 15 of the body 10 has the highest mechanical strength, the body 10 hardly deforms.

In the above embodiment, the outer surface of the shoulder body mounting nut 31 is tapered, but the outer surface is not limited to this, and may be a convex curved surface or a concave curved surface.

As is clear from the above explanation, according to the present invention, by adopting a simple structure in which an inclined surface that comes into pressure contact with the inclined part of the body made of a blow-molded product is formed on the outer surface of the shoulder body mounting nut, the medium bottle The tightening force can be received by the inclined portion of the body, and the force can be distributed and supported over the entire inclined group of the body, which has the greatest strength.

Therefore, the body hardly deforms, and the problems of water leakage and poor appearance caused by a decrease in the force for tightening the medium bottle, as in the conventional case, can be solved.

Furthermore, according to the present invention, the shoulder body mounting nut also strengthens the torso itself, improving impact resistance due to external forces, etc., and especially if the shoulder body mounting nut is placed near the connection part of the handle, It also prevents the torso from deforming when holding the handle.
