AI Technical Summary

Technical Problem

Existing stackable tubs face issues with instability during stacking due to contact between upper and lower tubs, leading to shaking and surface adhesion of stains, and have complex shapes that increase mold costs.

Method used

The tub design features outward protruding handles with specific thickness settings to create gaps between stacked tubs, ensuring stability and reducing stain accumulation.

Benefits of technology

This design stabilizes stacking, avoids mold complexity, and minimizes stain adhesion, thereby optimizing space utilization and reducing manufacturing costs.

Abstract

To provide a stackable tub without rattling.SOLUTION: Rattling is dissolved by receiving a lower face 2B of an upper tub grip on an upper face 2A of a lower tub grip, when upwardly / downwardly stacking tubs with each other while having the grip 2 outwardly protruding from both side ends of a bottomed cylindrical tub body 1 formed in a shape of getting narrower toward a lower portion, and close attachment thereof can be avoided by setting thickness in an upward-downward direction of the grip so as to have an interval between the tub bodies.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE The present invention relates to buckets, and more particularly to stackable buckets. [Background technology]

[0002] Buckets for holding hot water include flat tubs used for laundry or taking a bath, washbowls for washing the face, and bathtubs for use in the bathroom (Patent Document 1).

[0003] Among the above items, tubs are particularly large in size, which means that they are bulky and occupy a large amount of space during transportation in the distribution process, storage in warehouses, and display in stores. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Design Registration No. 1651952 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0005] Therefore, attempts have been made to reduce the space occupied in the planar direction by stacking tubs.

[0006] In the above, by forming the basin body in a shape that narrows downward, stacking becomes possible.

[0007] However, depending on where the upper and lower tubs come into contact when stacking, problems could arise where the stacking becomes unstable and wobbly, or the surfaces of the upper and lower tubs come into close contact with each other, making it impossible to remove them.

[0008] Therefore, as shown in Figure 6, an attempt has been made to provide a folded portion 11 at the upper end of basin 10 and to erect multiple ribs 12 below the folded portion so that when basins are stacked one on top of the other, the top surface of the folded portion of the lower basin receives the ribs of the handle of the upper basin, thereby creating a gap between the basin bodies.

[0009] However, the above-mentioned basin has a complicated shape, which increases the cost of the mold, and there is a problem that the folded portions and the end faces of the ribs are easily stained with scale and the like. [Means for solving the problem]

[0010] The present invention has been made with the objective of providing a bucket that overcomes the above-mentioned problems of the prior art.

[0011] In other words, the bucket of the present invention is characterized in that handles protrude outward from both side ends of the bottomed, cylindrical bucket body which tapers downward, and the vertical thickness of the handles is set so that when the buckets are stacked one on top of the other, the upper surface of the handle of the lower bucket receives the lower surface of the handle of the upper bucket, thereby leaving a gap between the bucket bodies. Effect of the Invention

[0012] According to the bucket of the present invention, when the buckets are stacked one on top of the other using the handles, there is a gap between the bucket bodies, so there is no waste in the molding, and since the handles extend from both sides of the bucket body, the stacking is stable and the bucket is less likely to get dirty with scale and other stains. [Brief description of the drawings]

[0013] [Figure 1] FIG. [Diagram 2] Same as above, plan view. [Diagram 3] Same as above, side view. [Figure 4] Same as above, cross-sectional view taken along line AA in Figure 2. [Diagram 5]Same as above, cross-sectional view of line BB in Figure 2. [Figure 6] FIG. BEST MODE FOR CARRYING OUT THEINVENTION

[0014] A concrete embodiment of the bucket of the present invention will be described below with reference to the attached drawings. Here, a basin will be taken as an example of the bucket.

[0015] In the drawing, reference numeral 1 denotes a basin body. Here, a horizontally elongated basin is shown, and the basin body 1 is a cylindrical basin with a bottom that tapers downward.

[0016] In the figure, reference numerals 2, 2 designate handles that protrude outward from both side ends of the basin body 1. The handles 2, 2 are made by protruding arc-shaped pieces of rectangular timber with thickness in the vertical direction, and are set so that the positions of the upper surface 2A and the lower surface 2B are aligned in the planar direction. The upper and lower surfaces are also flat.

[0017] When the basin bodies 1 are stacked one on top of the other, the upper surface 2A of the handle of the lower basin body supports the lower surface 2B of the handle of the upper basin body, and the vertical thickness of the handles is set so that a gap is created between the basin bodies (see Figures 4 and 5). [Explanation of symbols]

Claims

[Claim 1] This tub has a bottomed, cylindrical tub body tapering downward, and has handles that protrude outward in an arc shape from both ends of the tub, each handle being made of a rectangular cross-section with a thickness in the vertical direction, and the thickness of the handles in the vertical direction is set so that when tubs of the same configuration are stacked one on top of the other, the upper surface of the handle of the lower tub receives the lower surface of the handle of the upper tub, thereby leaving a gap between the tub bodies.
