Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a water pitcher mainly used for gardening.

<Prior Art> As a gardening pitcher, one described in Japanese Utility Model Application Publication No. 143554/1983 is known. As shown in FIG. 11, this conventional water pitcher was constructed by insert-molding a metal water supply pipe 31 into a pitcher body 30 made of synthetic resin. The base 32 of the water supply pipe is provided with a retaining portion such as a screw or an expanded portion to prevent the water jug main body 30 and the water supply pipe 31 from coming off.

<Problems to be solved by the invention> In the conventional water pitcher described above, the metal water supply pipe 31 is directly insert-molded into the synthetic resin pitcher body 30, so the mold for molding the pitcher body becomes large. , and became complicated, leading to an increase in mold cost. Further, the work of accurately inserting and holding the water supply pipe 31 into the mold is troublesome and requires skill, making it difficult to improve work efficiency. Moreover, insert molding had to be performed for each jug, making it unsuitable for mass production.

<Means for Solving the Problems> The present invention aims to provide a water jug that can reduce mold costs and improve production efficiency. In order to accomplish this task, the present invention takes the following measures.

In a water pitcher in which a metal water supply pipe protrudes from a synthetic resin pitcher body, the water supply pipe is inserted into the insertion hole of the pitcher body through a synthetic resin sleeve that is integrally fitted and fixed to the pipe base. Fitted and fixed.

<Example> As shown in FIGS. 1 and 2, the water pitcher according to the present invention is formed by integrally combining a pitcher body 1 made of synthetic resin and a water supply pipe 2 made of metal.

The jug main body 1 is divided into a body part 3 and a bottom part 4. The body 3 is a cylindrical body with openings at both ends, and the upper opening is a water inlet 5. A grip 6 is integrally formed on the outer peripheral surface of the body 3. A convex fitting convex portion 7 is formed in an annular shape on the lower end peripheral edge of the body portion 3 .

The bottom portion 4 is formed in the shape of a saucer with a slight standing wall portion 8 on the circumferential edge of the disc, and a fitting recess 9 for receiving the fitting convex portion 7 is formed in the upper end surface of the standing wall portion 8 in an annular shape. A boss portion 10 that is thicker than other portions is formed in a portion of the vertical wall portion 8 of the bottom portion 4.
A water supply pipe insertion hole 11 is provided in this boss portion 10.

The details of the insertion hole 11 are shown in FIGS. 3 and 4. This insertion hole 11 is a concentric large diameter hole 1
2 and a small diameter hole 13, with the large diameter hole 12 located on the outside. This large diameter hole 12
is formed into a tapered hole that expands outward, and the hole 1
A rotation stopper 14 having a flat surface is formed at the lower part of the rotation stopper 2 .

The body part 3 and the bottom part 4 have a fitting convex part 7 and a concave part 9.
They are integrally bonded or fused together via the , and the two are fixed in a watertight manner. At this time, so that the relative positional relationship between the insertion hole 11 and the grip 6 is always constant,
A positioning portion 15 having a so-called groin shape is provided in the fitting convex portion 7 and the concave portion 9. This positioning portion 15 is provided on the boss portion 10.

As shown in FIGS. 5 and 6, the metal water supply pipe 2 has a cross-shaped recess 17 formed in its base 16 by press working. As shown in FIGS. 7 and 8, there is a recess 17 in the pipe base 16.
A sleeve 18 made of synthetic resin is fitted and fixed to the outside so as to enclose it.

In order to fix the sleeve 18 to the pipe base 16, a large number of water supply pipes 2 are set in a mold, and a large number of moldings are simultaneously performed by injecting synthetic resin into the base 16. Since the sleeve 18 and the pipe 2 are fixed to each other through the recess 17, relative rotation between the two is prevented and the pipe 2 is watertight.

The outer peripheral surface of the sleeve 18 is formed into a tapered shape so as to fit into the large diameter hole 12 of the insertion hole 11, and a notch 19 is formed to fit into the rotation stopper 14 of the large diameter hole 12. There is.

The water supply pipe 2 to which the sleeve 18 is fixed is fitted into the insertion hole 11 through the sleeve 18 and fixed by adhesive or fusion.

Note that the means for preventing relative rotation between the pipe 2 and the sleeve 18 is not limited to providing the recess 17 in the pipe base 16, but may also be used by caulking a pin 20 to the pipe base 16 as shown in FIG. Alternatively, as shown in FIG. 10, the pin 20 may be fixed by spot welding or the like.

<Effects of the invention> According to the invention, unlike the conventional method of insert molding a pipe for each jug, it is possible to mold multiple metal pipes at the same time, and the work of inserting them into the mold is reduced. Since it is greatly shortened, the molding cycle can be shortened. There is also the advantage that the mold can be made smaller and simpler.
