BACKGROUND OF THE INVENTION This invention relates to a pail used mainly in a bathroom.

[0002]

2. Description of the Related Art In a conventional hand tub of this type, the tub portion and the handle portion are integrally formed of hard synthetic resin, and the cross-sectional shape of the ordinary handle portion is U-shaped or as shown in FIGS. It has an inverted U shape.

However, regarding the handle having an inverted U-shaped cross section,
When you hold it with one hand, your thumb will hit one edge of the inverted U-shape and the other four fingers will hit the U-shaped bend, but the area of your thumb is small Is unevenly distributed from the center line of the handle, the weight of the tub acts as a twisting force,
It takes a lot of force to support the tub horizontally while holding it. Moreover, the upper surface of the handle is dented like a gutter, and it looks thin and lacks robustness or reliability. On the contrary, if the handle has an inverted U-shaped cross-section, it looks good and the handle looks thick and has the above-mentioned robustness and reliability. The finger touches the U-shaped edge, and the weight of the tub acts as a concentrated load on the four fingers through this narrow edge, making it feel heavy and hurt the finger. In addition, regardless of the cross-sectional shape of the handle, the handle is a hard synthetic resin molded product integrated with the trough, so it becomes extremely slippery when wet with water. In short, it was difficult to use for the weak elderly and infants.

It is also possible to make the handle thicker in order to increase the cross-sectional shape of the handle, but the amount of resin used for molding increases. Further, if the wall thickness is increased in this way, the weight of the handle becomes heavy, and the empty pail may fall down due to the thickness of the handle, and these solutions are not practical.

[0005]

This invention is intended to improve the above-mentioned conventional drawbacks. The amount of resin required for molding is not so large that molding is easy, and it is not heavy and the handle portion is not heavy. Its purpose is to provide the market with easy-to-hold pail with a thick cross-section.

[0006]

In order to achieve the above-mentioned object, the present invention comprises a main body, a grip cylinder, and a fixing member, which are integrally molded independently of each other by a synthetic resin molding. It is composed of a trough portion and a grip barrel support portion, and the grip barrel support portion is symmetrical with respect to the outer peripheral surface of the trough portion and a central shaft portion having a vertically long cross-sectional shape portion extending in the radial direction of the trough portion and both side surfaces thereof. Is formed by a large number of protruding ribs formed at a predetermined pitch in the length direction of the central shaft portion, and the grip cylinder has an inner peripheral surface shape that contacts the outer peripheral surface of each protruding rib portion,
A single molded article, wherein the anchoring member is in contact and butt-edge face of the grip cylinder, and pails, characterized in that which had been fixed to the central shaft tip.

[0007]

According to this invention, the main body grip cylinder and the fixing member are separately molded as synthetic resin molded products, and then the grip cylinder is first inserted from the base side from the tip of the grip support portion.
The end surface on the base side is brought into close contact with the outer peripheral surface of the trough , the fixing member is fixed to the tip of the handle mounting portion, and the grip cylinder is fixed to the grip support portion.

In the device of the present invention assembled in this manner, the inner peripheral surface of the grip cylinder is in close contact with the outer peripheral surface of the protruding rib portion. When you use it, use it like a normal pail.

The base portion of the central shaft portion 12 is a reinforcing rib 19 extending in the axial direction of the peripheral surface of the trough portion 10. Further, a bifurcated portion 20 which is bifurcated is formed at the tip of the central shaft portion 12, and the hook 21 is engaged with the fixing member C. Further, the outer shape of each of the overhanging rib portions 13 is formed such that the base side of the grip tube supporting portion 11 is large and gradually becomes smaller toward the tip side thereof (see FIGS. 1 and 2).
The thickness of each part of the main body 10 is formed so that there is little difference as a whole.

In the figure, B is a grip cylinder, the inner peripheral surface 3 of which.
The cross-sectional shape of 0 is a shape that envelops the outer peripheral surfaces of the respective projecting rib portions 13 and closely adheres to them, and has a substantially taper shape with a thick root side and a thin tip side, and the root end has the reinforcing rib 19 described above. becomes enlarged portion 31 of the morning glory type shape to completely cover and the base-side end face 32 is a shape in close contact with the outer peripheral surface of the tub portion 10, the distal end surface 33 is a shape close contact butt and the fixing member C.

Further, axial ribs 34 projecting inward are provided on the upper and lower portions of the inner surface of the grip cylinder B so as to fit with all the recesses 18 of each projecting rib portion 13. Although the material of the grip cylinder B is not particularly limited, in the embodiment, the grip cylinder B is made of synthetic resin which is slightly softer or more elastic than the main body A, for example, EVA, other elastomer resin, elastomer resin and polyethylene mixture or elastomer. It is formed of a material such as a synthetic rubber as well as a copolymer of a resin and a resin such as polyethylene or polypropylene. The wall thickness is about the same as the body A.

In the embodiment of the present invention, the hard synthetic resin molded product means that it is not deformed by pushing with a finger, and the synthetic resin molded product having softness or elasticity is such that it is bent by a finger or bent by a grip force. Say something.
