[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jug having an improved connection between a jug body and a nozzle, and more particularly to a jug suitable for use in gardening.

[0002]

2. Description of the Related Art In general, a jug is composed of a jug main body for storing water and a nozzle for pouring an appropriate amount of water in the jug main body to a target location. The nozzle is formed of a long and slender metal from such a jug as a jug in terms of design or usage (in a complicated narrow place, for example, when water is injected into the inside of trees with overgrown leaves), and this nozzle is attached to a resin jug body. There is a press-fit configuration.

[0003] However, in the case of a jug having such a nozzle mounting structure by press-fitting, a large shock is applied to the connecting portion between the jug main body and the nozzle by grasping the nozzle and lifting the jug or hitting the nozzle against something. In such a case, the nozzle may rotate with respect to the jug main body or fall off.

[0004] In order to prevent this, a connection portion between the nozzle and the jug main body may be screwed or a flange may be provided at an end of the nozzle.

[0005] As a screw-in type jug,
There is one described in JP-A-143554. This will be described with reference to FIG. 8. The nozzle 2 is screwed and fixed to the mounting portion 1 on the jug main body side. The mounting portion 1 is provided with a female screw 1A, the base end of the nozzle 2 is provided with a male screw 2A, and the female screw 1A is screwed with the male screw 2A, whereby the nozzle 2 is fixed to the mounting portion 1.

As a jug provided with a flange portion, there is one disclosed in Japanese Utility Model Laid-Open No. 60-38563. This is shown in FIG.
It will be described based on.

In the figure, reference numeral 4 denotes a jug main body, and reference numeral 5 denotes a nozzle. A flange 6 is formed at the base end of the nozzle 5. A male screw cylinder 7 is attached to the lower part of the jug main body 4. A cap nut 8 is screwed into the male screw cylinder 7, and a flange portion 6 of the nozzle 5 and a packing 9 are interposed therebetween, and the nozzle 5 is attached to the jug main body 4.

[0008]

However, none of the above-mentioned prior arts is provided with any means for preventing rotation of the nozzle. For this reason, the mounting part becomes loose due to aging, and the nozzle may rotate with respect to the jug main body, or in the worst case, the nozzle may fall out of the jug main body, and the reliability of the product will be significantly deteriorated. There is a problem.

Further, when the flange portion 6 is formed on the nozzle 5, there is a problem that the manufacturing cost increases and the structure becomes complicated. When the nozzle 5 is formed of metal,
Such a problem is particularly large.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a jug with improved nozzle reliability by taking measures to prevent rotation and dropout of the nozzle jug body. With the goal.
