Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a water bottle, and more particularly to a water bottle having a body ring fitted in a body portion.

[Conventional technology]

It has been conventionally practiced to fit and fix a body ring on the body of a water bottle and to attach a hanging string or a handle using the body ring.

In this case, as a means for fitting and fixing the body ring on the outer periphery of the body portion, conventionally, a method of forcibly fitting in the vertical direction or screw fitting has been used.

[Problems to be solved by the device]

However, the method of forcibly fitting in the up-down direction cannot obtain sufficient pull-out strength, and the method of screw-fitting requires forming the groove on both the water bottle and the body ring. There is a problem that the mold becomes complicated and the cost becomes high.

As another method of fitting and fixing the body ring, it is conceivable to use bayonet fitting for obtaining a reliable fitting. However, in this method, an engaging collar is formed on the inner peripheral surface of the upper end of the body ring, and a bayonet claw for press-contacting the bayonet fitting surface of the water cylinder body is provided on the inner peripheral surface of the lower end so as to project. On the inner surface of the ring, a bayonet claw is protrudingly provided on the lower portion of the engaging flange on the upper portion. Such a structure has a drawback that a so-called undercut portion is generated in molding and the molding die is complicated.

Therefore, an object of the present invention is to provide a water bottle which adopts bayonet fitting and can easily form a body ring.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention is a water bottle in which a body ring 3 is fitted and fixed to the outer circumference of a body portion 2 of a water bottle body 1, and a separation portion 4 is provided on the outer circumference of the body portion 2 at regular intervals in the circumferential direction. Forming a rib-shaped body ring receiving portion 5,
A partly engaging rib 6 is provided on the upper surface of the above, and a bayonet fitting surface 7 is formed on the lower surface of the water bottle main body 1 which inclines downward as it goes in a fixed direction in the circumferential direction from the separating portion 4, An engaging collar 8 to be placed on the upper surface of the body ring receiving portion 5 is formed on the inner peripheral edge of the upper end of the body ring 3, and a notch 9 that fits the engaging rib 6 is formed on the collar 8 and below the notch 9. Is formed with a bayonet claw 10 which freely passes through the separating portion 4 and has a circumferential length shorter than the notch 9, and the bayonet claw 10 is attached to the bayonet fitting surface 7 by relative rotation of the water bottle body 1 and the body ring 3. The engagement rib 6 is fitted into the notch 9 at the deepest fitting between the bayonet claw 10 and the bayonet fitting surface 7.

[Action]

When the body ring 3 is fitted and fixed to the water bottle body 1, when the bayonet claw 10 of the body ring 3 is passed through the spacing portion 4 of the body ring receiving portion 5, the engaging collar 8 engages with the upper surface of the body ring receiving portion 5. Place on the rib 6. When the body ring 3 is rotated, the bayonet claws 10 are pressed against the bayonet fitting surface 7 on the lower surface of the body ring receiving portion 5. When the body ring 3 is rotated by a certain angle or more, the engaging rib 6 fits into the notch 9 of the engaging collar 8 and the body ring 3
Is integrated with the water bottle body 1.

〔Example〕

In the water bottle of the embodiment shown in the accompanying drawings, an opening 11 and a screw portion 12 for a lid are formed on an upper portion of a water bottle body 1, and a screw portion 12 for a lid is formed.
A rib-shaped body ring receiving portion 5 is formed around the entire lower portion of the.

The upper surface of the body ring receiving portion 5 is formed so as to form a horizontal surface, and a small engaging rib 6 is projectingly provided inside thereof in the middle thereof.
The body ring receiving portion 5 is separated by the spacing portion 4 at four equal positions in the circumferential direction. A bayonet fitting surface 7 is formed on the lower surface of each of the body ring receiving portions 5 separated at four positions, which gradually inclines toward the bottom surface of the water bottle in a certain direction from the end portion on the separation portion 4 side (first). (See Fig. 4). A depth of the bayonet fitting surface 7 is a horizontal surface, and a stopper portion 13 protruding at the same height as the body ring receiving portion 5 is formed. The stopper portions 13 are formed only at the two opposing body ring receiving portions 5.

On the other hand, an inward engaging collar 8 is formed on the inner peripheral surface of the upper end of the body ring 3. The engaging collar 8 is formed to have a diameter and a width that can be placed on the upper surface of the body ring receiving portion 5.

The engaging collar 8 has a notch 9 that fits with the engaging rib 6.
Are formed in four equal positions. A bayonet claw 10 is formed below the notch 9. Bayonet claw 10
Is projected downward in a U shape, and its circumferential length is
The cutout 9 is formed to have a length shorter than the above-mentioned notch 9 and capable of freely passing through the spacing portion 4 in the vertical direction.

The water bottle of the embodiment is constructed as described above, and after the body ring 3 is fitted around the opening portion 11 and the bayonet claw 10 is passed through the separating portion 4 as shown by the one-dot chain line arrow in FIG. It is fitted and fixed by rotating it in the direction of the bayonet fitting surface 7.

At the time when the bayonet claw 10 passes through the separating portion 4,
As shown in FIGS. 2 and 4, the engaging collar 8 rests on the engaging rib 6. When the body ring 3 is rotated in the direction of the arrow in FIG. 4 from this state, the upper surface of the bayonet claw 10 comes into contact with the bayonet fitting surface 7, and the pressing force becomes stronger as the rotation progresses. When the bayonet claw 10 rotates by a certain angle α and hits the stopper portion 13 (see FIG. 5), the engaging rib 6 fits into the notch 9 (see FIG. 3), and the body ring 3 is attached to the water bottle body 1. Be integrated.

[Effect of device]

As described above, the water bottle of this invention is one in which the body ring 3 is fitted to the water bottle body 1 with the bayonet. The notch 9 of the engaging collar 8 of the body ring 3 and the bayonet claw 10 are vertically opposed to each other. Since the bayonet claw 10 is in the position and the bayonet claw 10 is shorter than the notch 9, the mold for molding the upper surface of the bayonet claw 10 can be pulled out upward through the notch 9. For this reason, there is an effect that the molding die of the body ring 3 becomes simple, and there is an effect that a large fitting strength and accurate positioning can be achieved by the bayonet fitting.
