Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bucket with a synthetic resin handle.

[0002]

[Prior Art]

 Conventionally, a bucket with a synthetic resin handle is excellent in chemical resistance, water resistance, and electric insulation, and is generally used for storing and transporting foods and storing dust.

[0003]

[Problems to be solved by the device]

 However, in the conventional bucket with handle, the main body and handle are separately molded and assembled, so that two molds are required, and the molding has to be performed separately, which requires assembly man-hours.

An object of the present invention is to solve the above-mentioned conventional problems and provide a bucket with a handle that can be manufactured in one step.

[0005]

[Means for Solving the Problems]

 The gist of the present invention is that the handle is integrally formed on the main body so as to be bendable at the membrane-shaped connecting portion. As a material used for the bucket of the present invention, polypropylene having a hinge effect is preferably used. The shape of the bucket according to the present invention is not particularly limited, and may be a substantially cylindrical shape with a bottom, a rectangular box shape, or a through hole may be formed in the side wall or the bottom wall. Further, the lid may be detachably covered. The film-like connecting portion of the bucket of the present invention preferably has a thickness of 0.3 to 0.8 mm and a width of 5 to 7 mm so as to exhibit a hinge effect and have sufficient strength.

In order to mold the bucket of the present invention, a pattern forming portion is provided on the parting surface outside the side of the pattern attachment forming portion of the injection molding die for molding the conventionally known bucket body. A mold in which the pattern forming part and the pattern attachment forming part are connected by a film gate may be used. The bucket of the present invention is formed by using the above-mentioned mold, in which the molten resin injected into the mold by injection molding is filled from the pattern attachment forming part of the mold to the pattern forming part through the film gate. To be done. The formed bucket with a handle is obtained in a state where the bucket body and the handle are joined by the film-like connecting portion formed by the film gate. For more details, in the state where the handle is held horizontally via the membrane connection part to the side of the handle attachment part that has a substantially U-shaped cross section and is protruded outward from the lower end of the folded edge of the bucket body opening. It is integrally formed. In order to orient the molecular arrangement of the membranous connection portion in the longitudinal direction, it is preferable to stretch the handle by bending it 4 to 5 times in an uncooled state after molding.

[0007]

[Action]

 In the bucket of the present invention, the handle is formed integrally with the main body so that the handle can be bent at the film-shaped connection portion, so that the bucket can be molded in one step, and the assembly step is unnecessary.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention. The bucket 1 injection-molded from polypropylene has a membranous shape on the side of the handle attachment part 12 having a substantially U-shaped cross section, which projects outward from the lower end of the folding edge of the main body 11 having a substantially cylindrical shape with a bottom. The handle 14 is integrally molded through the connecting portion 13 while being held horizontally. The handle attaching portion 12 plays a role of maintaining a vertical interval so that when the plurality of buckets 1 are stacked and stacked during storage or transportation, they can be easily removed. When the bucket 1 is used, the handle 14 held horizontally is grasped and lifted up for use.

The bucket 14 of the present invention is not limited to a single handle, but as shown in FIG. 2, two handles are juxtaposed in symmetry, and protrusions and recesses that can be fitted to each other are provided on the surfaces facing each other. A portion may be provided, and when used, the two pieces may be erected so that the protrusions and the recessed portions are fitted to each other to prevent the bucket from swinging. The cross-sectional shape is not particularly limited, but from the viewpoint of maintaining strength and reducing the amount of raw material used, it is preferably H-shaped.

[0010]

[Effect of the device]

 Since the bucket of the present invention is constructed as described above, it can be manufactured efficiently and inexpensively. When the handle is held horizontally as in the embodiment, it is easy to grasp and lift the handle during use.
