Description

  The present invention relates to a container used as a bathtub or a basin.

  A bathtub or a basin used for a bathroom is generally a container having a substantially inverted conical shape, having a bottom on the small diameter side, and an opening on the large diameter side. Before and after use of the container, the container is placed on the floor surface with the opening side facing up or with the opening side facing down. However, with the opening side facing upward, the liquid remains on the bottom inside the container and is not discharged, which is unsanitary due to the occurrence of scales and germs. In addition, in the state where the opening side is facing down, the liquid remaining inside the container is difficult to evaporate, and the periphery of the opening side is grounded. I didn't get it.

  For such problems, a part of the container has a shape that functions as a support base, and by grounding this support part, the container can stand on its side or in a tilted state, and the liquid remaining inside the container Proposals have been proposed to promote the emission of

In Patent Document 1, a part of a container side wall is formed into a planar shape, and before and after use of the container, the planar part can be grounded so that the container can be placed on the floor sideways. However, when this flat part is grounded and placed on the floor, the contact area with the floor is large, so there is a large amount of liquid adhering to the grounding surface of the flat part, and there is a problem that scales and germs are easily derived from the flat part. It was.
Further, even when the container is placed on a free-standing floor sideways, the flat portion of the side wall portion on the inner periphery of the container is in a horizontal state, and the discharge effect of the liquid remaining inside the container is not sufficient.

  In Patent Document 2, a flat portion is provided on a part of the handle of the container, and the flat portion is grounded, so that the opening side of the container main body can be tilted downward. When the container main body is tilted and placed on the floor, the liquid remaining in the container is sufficiently discharged, but the handle is semi-arced, so this container is a small size as in this embodiment. Although there is no particular problem with a cup, in the case of a container that needs to draw a lot of liquid, such as a bathroom cup, keep the container horizontal because the gripping position is away from the container body. For this reason, the force generated in the hand is increased, making it difficult to pump the liquid. For the same reason, there is a problem that it is difficult to secure the strength and rigidity around the handle.

  The present invention includes a rib-shaped support portion on the container side wall, and by grounding this support portion, the grounding area is reduced and the container body is placed on the floor in a self-supporting manner, thereby reducing the amount of liquid adhering to the container. It is another object of the present invention to provide a container characterized by facilitating discharge of adhering liquid.

 In order to achieve the above object, the present invention provides the container described in (1) and (2).

  (1) A plurality of support portions projecting in the direction from the container opening side to the container bottom side are provided adjacent to the outer peripheral surface of the container side wall portion, and the container bottom portion is placed in a horizontal plane by grounding the support portions with respect to the horizontal plane. When the angle between the container bottom and the container side wall is θ, the main body is supported so that the angle between the container bottom and the horizontal plane is smaller than θ. Container to be used.

  According to this container, when the container is placed on a self-supporting floor, the surface of the portion near the floor of the inner peripheral surface of the container side wall is inclined lower on the container opening side than the container bottom, and the liquid remaining inside the container is It is discharged from the container opening side by the action of gravity.

  In addition, the addition of the support portion does not prevent the container from being molded by two molds that are punched in the direction of the central axis of the container body.

  (2) The container according to (1), wherein the support portion is formed on the outer peripheral surface of the container side wall portion so as to be 180 degrees symmetrical with respect to the central axis.

  According to this container, when a plurality of containers are stacked, the containers can be stacked stably while ensuring a space between adjacent containers so that the central axis of the container body is coaxially aligned.

  According to the present invention, by placing the container on the free standing floor, the discharge of the liquid remaining inside the container is promoted, and at the same time, the amount of liquid adhering to the grounding portion is reduced by reducing the ground contact area with the floor. In addition, it is possible to suppress scale and mold generated in the container. Further, when a plurality of containers are placed with their central axes coaxially aligned and faced down, the discharge of the liquid remaining inside the containers is not hindered. Moreover, since the rigidity of a container main body increases by addition of a support part, the intensity | strength of a container main body increases.

[First Embodiment]
A first embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, the container 1 has a disk-shaped bottom portion 21 and an annular side wall portion 22 in one body, a main body portion 20 having one end of the side wall portion 22 open, and a side wall portion 22. The outer peripheral surface is constituted by a pair of support portions 5 formed so as to protrude in a direction from the opening side of the main body portion 20 to the bottom portion 21.
Further, an annular flange 3 is formed on the peripheral edge of the side wall portion 22 on the opening side, and an annular leg 4 is formed on the outer surface of the bottom portion 21.

  The container 1 is mainly used as a bathroom basin or a bathtub. The side wall part 22 is formed in a substantially inverted truncated cone shape whose diameter increases from the bottom part 21 toward the opening side of the side wall part 22.

  As shown in FIG. 2, the support part 5 is extended in the radial direction of the outer peripheral surface of the side wall part 22, and the several support part 5 is provided adjacently. Further, the plurality of support parts 5 are formed in the same shape, and when the support part 5 is faced down to the horizontal plane 7, the plurality of support parts 5 are simultaneously grounded to the horizontal plane 7.

As shown in FIG. 3, the side wall-side ridge line 51 of the support portion 5 is set so as to approach the center line O of the main body portion 20 from the opening side of the side wall portion 22 toward the bottom portion 21. When the support portion 5 is faced down and grounded to the horizontal surface 7, when the angle formed between the bottom portion 21 and the side wall portion 22 is θ ₁ , the angle θ ₂ formed between the bottom portion 21 and the horizontal surface 7 is equal to the bottom portion 21 and the side wall portion 22. It is set to be smaller than the angle θ ₁ formed by.

  In other words, when the support portion 5 is faced down and grounded to the horizontal surface 7, the vertical line V on which the center of gravity W of the container 1 acts as gravity corresponds to the opening-side ground portion 53 of the support portion 5 and the bottom side of the support portion 5. The support portion 5 is formed so as to be in a state orthogonal to the line segment connecting the grounding portion 54. Therefore, when the support portion 5 is faced down and grounded to the horizontal surface 7, the main body portion 20 is placed on the floor so that the bottom portion 21 intersects the horizontal direction so as to be able to stand on its own.

  In a state where the support portion 5 is faced down and grounded to the horizontal surface 7, the side wall side ridge line 51 of the support portion 5 formed in the direction from the opening side of the side wall portion 22 to the bottom portion 21 is recessed with respect to the horizontal surface 7. It is formed into a shape. In that case, the side wall-side ridge line 51 is grounded to the opening-side grounding portion 53 and the bottom-side grounding portion 54, but the intermediate portion is not grounded because a gap is formed between the horizontal surface 7. Therefore, when the support portion 5 is faced down and grounded to the horizontal surface 7, the grounding area is reduced, the amount of liquid adhering to the vicinity of the grounding portion is reduced, and air permeability is ensured, so that the adhering to the vicinity of the grounding portion Liquid drying is promoted.

  Further, as shown in FIG. 4, when the hand H is gripped from the upper edge of the flange 3 to the bottom side ridge line 52 of the support portion 5, the hand H is stably held by the bottom side ridge line 52. 1 pumping becomes easy.

  Moreover, since the support part 5 is formed in the shape which has a role as a rib which protruded in the side wall part 22 toward the bottom part 21 from the opening side of the side wall part 22, the rigidity of the main body part 20 increases, and the main body part 20 is increased. When the container 1 is pumped by putting a liquid into the interior of the container, deformation of the main body 20 is suppressed, and the strength and durability of the main body 20 are improved. Alternatively, as the rigidity of the main body portion 20 is increased by the addition of the support portion 5, the thickness of the main body portion 20 can be reduced to reduce the weight. It is possible to increase the diameter and depth of the main body 1 and increase the amount of liquid that can be pumped by utilizing the fact that the rigidity of the main body 20 is increased by adding the support 5.

As shown in FIG. 5, according to the shape of the support portion 5 described above, the side wall side ridge line 51 of the support portion 5 approaches the center line O of the main body portion 20 from the opening side of the side wall portion 22 toward the bottom portion 21. Therefore, the container 1 is molded by the lower mold 8 that is punched in the direction of arrow D and the upper mold 9 that is punched in the direction of arrow E. When molding the container 1, both the lower mold 8 and the upper mold 9 can be punched in the direction of the center line O, and can be molded only with the two molds of the lower mold 8 and the upper mold 9. Therefore, it is possible to prevent an increase in manufacturing cost.
[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 6, in the second embodiment, a plurality of support portions 5 protruding adjacent to the outer peripheral surface of the side wall portion 22 are also provided at positions 180 degrees symmetrical with respect to the central axis O. ing. Further, the flange 3 is provided with a hole 6. Note that, in the following embodiments, constituent elements that are the same as those described in the first embodiment are denoted by the same reference numerals, and redundant descriptions thereof are omitted.

  As shown in FIG. 7, according to this embodiment, when a plurality of containers 1 are stacked, the central axes O of the main body portions 20 are coaxially overlapped, and the inner peripheral surface of the side wall portion 22 has adjacent containers. Since the plurality of bottom surface side ridge lines 52 or the plurality of bottom side grounding portions 54 and the center axis O are in contact with the object, the plurality of containers 1 can be stably stacked. In that case, since a space can be secured between the adjacent main body portions 20, drying of the liquid remaining inside the main body portion 20 is promoted. As shown in FIG. 7, when the plurality of containers 1 are stacked with the bottom portion 21 facing upward, the liquid flowing down to the flange 3 does not hinder the discharge of the liquid remaining inside the main body portion 20, and the hole 6 Discharged from.
