Description

[Detailed Description of the Invention] The present invention relates to an improvement in the shoulder structure of a container such as a magic bottle, particularly in the mounting structure of a shoulder cover.

BACKGROUND ART Containers such as magic bottles have been proposed in the past, in which a shoulder body is placed and fixed on the upper end of an exterior body that houses an inner container such as a double vacuum bottle, and the upper surface of the shoulder body is covered with a shoulder body cover. This shoulder cover is usually used from two viewpoints: decorative, which allows the upper surface of the shoulder to vary in shape and color, and structural, which forms the upper wall of the spout. Ru.

However, because conventional shoulder covers are simply attached by force-fitting the inner circumference to the inner surface of the shoulder body, warpage occurs on the outer circumference of the shoulder body cover, causing a warpage between the shoulder body cover and the upper surface of the shoulder body. This has the disadvantage that gaps are formed, resulting in poor appearance, and dust and the like accumulate in the gaps, resulting in filth. Therefore, in the past, a screw was inserted into the shoulder body cover from below the shoulder body, and the outer circumference of the shoulder body cover was joined to the shoulder body, but in this case, the shoulder body cover was attached to the entire circumference. Since it had to be held evenly and tightly against the shoulder body, multiple screws and complicated screw fixing work were required.

The present invention was devised in view of these conventional drawbacks, and its purpose is to provide a shoulder structure for containers such as magic bottles that allows the shoulder body cover to be easily joined and fixed to the shoulder body without using any screws. do.

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.

The drawing shows a magic bottle as an example of the container according to the present invention, where 1 is an exterior body made of synthetic resin, 4 is an inner container made of a vacuum double bottle housed inside the exterior body 1, and 5 is an exterior body. 1 is a shoulder body made of synthetic resin which is placed and fixed on the upper end of the shoulder body 5 and has a handle 6 and a spout 7 integrally molded; 16 is a stopper body; and 17 is a shoulder body cover that covers the upper surface of the shoulder body 5.

At the upper end of the exterior body 1, a standing wall 2 whose front side is inclined upward and whose front and rear sides are cut out is provided, and an inner flange 3 is protruded from the inside.

A male screw 8 is provided on the outer periphery of the lower end of the shoulder body 5, and the shoulder body 5 is placed on the upper end of the exterior body 1, and a nut 9 is attached to the male screw 8 (see FIGS. 1 and 3). By screwing together the outer body 1 with the nut 9.
The inner flange 3 is pushed up, and the shoulder body 5 is placed and fixed on the upper surface of the exterior body 1. At this time, the groove 10 on the outer surface of the spout 7 of the shoulder body 5 and the root portion 6a of the handle 6 engage with the front and rear notches 2a and 2b of the rising wall 2 of the exterior body 1. A bottle spout holder 12 is provided at the lower end of the shoulder body 5 and is crimped to the mouth of the inner container 4 via a cap rubber 11 (see FIG. 1). An inner wall 13 into which the screws 16 are screwed is integrally formed, and six engaging grooves 14 are provided on the inner surface of the inner wall 13. Further, an outer wall 15 is provided on the outer periphery of the shoulder body 5, and when the shoulder body 5 is mounted and fixed on the exterior body 1, this outer wall 15 faces the inside of the rising wall 2 with a certain gap.

The shoulder body cover 17 is made of synthetic resin and has a substantially annular plate shape, and has an engaging pawl 18 that engages with the outside of the spout 7 of the shoulder body 5 and a beak that covers the top surface of the spout 7 on the front side. Part 1
9, and an inner cylinder 20 that is inclined so that the front side is gradually higher and an outer cylinder 22 of a constant height with cutouts on the front and rear sides are vertically provided on the lower surface. Six engaging protrusions 21 are provided on the outer surface of the inner cylinder 20 to forcibly fit the inner cylinder 20 to the inner surface of the inner wall 13 of the shoulder body 5, and the engaging protrusions 21 are inserted into the engaging grooves 13 of the inner wall 13. It is prevented from coming off by engaging with it. Also,
The outer cylinder 22 is press-fitted between the upright wall 2 of the outer case 1 and the outer wall 15 of the shoulder body 5, and is clamped and fixed between both walls. In this way, the shoulder body cover 17 is fixed to the shoulder body 5 on both the inner circumference side and the outer circumference side and over the entire circumference, so that the shoulder body cover 17 is closely joined to the shoulder body 5. , no gaps will occur.

In the above embodiment, the shoulder body cover 17 is fitted and fixed after the shoulder body 5 is placed and fixed on the exterior body 1. However, the method is not limited to this. After fitting into the shoulder body 5, the shoulder body 5 may be placed and fixed on the exterior body 1.

Further, the outer cylinder 22 is not limited to being simply sandwiched between the rising wall 2 and the outer wall 15, but may include an engaging protrusion or the like on the inner or outer surface of the outer cylinder 22 to engage with the rising wall 2 or the outer wall 15. You can.

Furthermore, as in the above embodiment, the rising wall 2 and the outer wall 15 may have the same height, or the upper end of the rising wall 2 and the upper end of the outer wall 15 may have a vertical step.

As is clear from the above description, according to the present invention, the inner cylinder of the shoulder body cover is forcibly fitted to the inner surface of the inner wall of the shoulder body, and the outer cylinder of the shoulder body cover is connected to the upright wall of the exterior body and the shoulder body. Since it is sandwiched between the shoulder body cover and the outer wall, the shoulder body cover is positioned and fixed with respect to the shoulder body and the exterior body on both the inner circumferential side and the outer circumferential side, and there is no gap between the shoulder body cover and the shoulder body. Never occurs. Furthermore, when attaching the shoulder body cover, it can be assembled simply by fitting without using any attachment parts such as screws, so that workability is extremely improved.
