Abstract

PROBLEM TO BE SOLVED: To provide a watering pot having a watering direction unlimited by a handle by extending a brim edge from the upper end of a cylindrical vessel in the outer direction and fixing a metallic watering pipe to a water- passing opening protruded from the periphery wall of a vessel. SOLUTION: The objective watering pot is obtained by extending a brim edge 24 from the upper end of a holdable cylindrical vessel 1 made of a thermoplastic resin in the outer direction and fixing a metallic watering pipe 3 to a water-passing opening 11 protruded from the periphery wall of a vessel 1. The objective watering pot can be obtained by fixing the metallic watering pipe 3 by inserting the heated metallic watering pipe 3 into the water-passing opening 11 and cooling and solidifying the inserted water-passing opening 11. The objective watering pot can have a thermoplastic resin cap 4 having an opened water-discharging opening 42 formed on the periphery wall of a cylindrical plug body 41, arranged at the tip of the watering pipe 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a jug.

[0002]

2. Description of the Related Art Conventionally, a jug in which a metal injection pipe is obliquely attached to the lower end of a thermoplastic resin cylindrical container having a handle by insert molding is disclosed in, for example, JP-A-8-224050. As is well known.

[0003]

However, in such a conventional jug, there is a problem that the direction of irrigation is limited because the grip is gripped with one hand to irrigate.

An object of the present invention is to solve the above-mentioned conventional problems and to provide a jug in which the direction of irrigation is not limited by a handle.

[0005]

According to a first aspect of the present invention, there is provided a jug in which a flange is extended outwardly from an upper end of a graspable thermoplastic resin cylindrical container, and is obliquely upward from a lower end of a peripheral wall of the container. A metal water pipe is fixed to a water port protruding from the metal pipe.

The water jug according to the second aspect of the present invention is further characterized in that a heated metal water pipe is inserted into a water port, cooled, solidified, and fixed.

The jug according to the third aspect of the present invention is further characterized in that a tub made of a thermoplastic resin having a water outlet opened on the peripheral wall of the cylindrical plug is detachably fitted to the tip of the water pipe. Sign.

In the jug of the invention according to claims 1 to 3,
The material of the thermoplastic resin cylindrical container is not particularly limited,
For example, polypropylene, high density polyethylene and the like can be mentioned.

[0009] The flange edge extending outward from the upper end of the container,
It is not necessary to be integrally formed with the container, and an annular ridge formed separately and projecting from the lower surface is fitted into an annular groove provided on the upper end of the container, or is formed on the lower surface. The vertically hanging wall may be fitted to the inner peripheral surface of the container. In the former case, it is preferable that a packing made of an elastic body such as synthetic rubber is interposed in order to eliminate the gap between the annular ridge and the annular groove and secure watertightness.

The flange edge does not necessarily have to be provided concentrically at the same width on the entire circumference of the container. For example, the flange edge is formed at the end of the flange edge protruding substantially in the shape of a beak on the water flow opening side. A water pipe may be inserted through the through hole so that the water pipe can be stably held.

The inner diameter of the water passage port projecting obliquely upward from the lower end of the peripheral wall of the container is the same as the outer diameter of the metal water pipe so as not to form a gap with the outer peripheral surface of the metal water pipe. Preferably, the diameter is slightly smaller.

In the jug of the invention according to claims 2 and 3,
When the molten thermoplastic resin is cooled and solidified, it shrinks into the groove, etc. at the insertion part of the metal water pipe into the water inlet, and enhances the adhesion with the thermoplastic resin, and drops off In order to prevent this, it is preferable to apply knurling to the outer surface, to form a groove in the circumferential direction, or to connect a plurality of recessed portions.

The method of heating the metal water pipe is not particularly limited, but the high-frequency induction heating method in which an alternating current is supplied to the induction heating coil and heated by an eddy current flowing in response to a change in the magnetic field is efficient. It is preferable because the heating rate is high and uniform heating can be performed.

In the water jug according to the third aspect of the present invention, the material of the thermoplastic resin cap removably inserted at the tip of the water pipe is not particularly limited. No.

The irrigation pressure and irrigation direction can be changed by preparing a plurality of types of thermoplastic resin caps having different sizes, numbers, and opening angles of water outlets and exchanging them. You may do so.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a jug according to the third aspect of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a jug according to the third aspect of the present invention, and FIG. 2 is a perspective view showing a use state of the jug according to the third aspect shown in FIG.

In FIG. 1, reference numeral 1 denotes a grippable polypropylene cylindrical container having an inner diameter of about 90 mm at an upper end, an inner diameter of about 60 mm at a lower end, and a depth of about 137 mm at a water inlet side. From the lower end, a water passage 11 is projected obliquely upward at an angle of 40 degrees with respect to the bottom surface.

Reference numeral 2 denotes a lid made of a polypropylene curved plate formed separately from the container 1. An annular ridge 22 projecting from the lower surface of the substantially annular portion 21 of the lid 2 is An annular hanging wall 23 which is fitted from above the annular packing 13 into an annular groove 12 provided on the upper end of the first annular groove 12 and which is vertically provided inside the annular groove 12.
Is inserted into the inner peripheral surface of the container 1.

A substantially elliptical through-hole 27 is formed at the end of the substantially beak-shaped protrusion 26 protruding from the substantially annular portion 21 of the lid 2, and is formed on the opposite side of the substantially beak-shaped protrusion 26. A flange 24 extends.
Further, a reinforcing ridge 25 is vertically provided on a peripheral edge of the lid 2.

Reference numeral 3 denotes a metal water pipe, whose outer peripheral surface at one end is knurled. The knurled portion 31 of the metal water pipe 3 heated by the high-frequency induction heating method is inserted into the water hole 11 of the container 1, cooled, solidified and fixed.

The other end of the water pipe 3 is inserted into and held by the substantially elliptical through hole 27 of the lid 2, and a heat outlet 42 having a water outlet 42 opened on the peripheral wall of the cylindrical stopper 41 at the tip. A cap 4 made of a plastic resin is detachably inserted.

In use, as shown in FIG. 2, irrigation is performed by grasping the container 1 from an arbitrary direction and tilting the container 1 toward the water inlet 11. By rotating the cap 4 inserted into the end of the water pipe 3 in the circumferential direction, the direction of irrigation can be changed, and a plurality of types of water outlets prepared in advance differing in size, number, and opening angle. By replacing with the cap 4, the irrigation pressure and the irrigation direction can be changed.

[0023]

Since the jug of the first aspect of the present invention is constructed as described above, the direction of irrigation is not limited by the handle, and the container is gripped by the flange so that the container does not slip down. Can be irrigated. Since the jug of the invention of claim 2 is configured as described above, it can be manufactured at low cost with a small molding machine without using a mold having a complicated structure such as insert molding. . Claim 3
Since the jug of the invention of the invention is configured as described above, it is not necessary to bend the tip of the water pipe, and by covering the tip of the water pipe, damage to the fingertips or the like can be prevented.
