[0004] <o000025>By the way, immediately after washing things using a bucket, since the things become waterlogged, there may be a case where it is desired to drain the water adhering to the things near the bucket.
[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a draining device and a container with a tray that can immediately drain water from things taken out of the container.
Means for Solving the Problems
[0006] A draining device according to one aspect of the present invention includes a mounting portion attached to an upper end portion of a peripheral wall of a container, and a mounting plate attached to the mounting portion so as to be movable parallel between a lower limit position and an upper limit position, and at least one of the mounting portion and the mounting plate is made of synthetic resin.
[0007] A container with a tray according to one aspect of the present invention comprises a container made of synthetic resin having a bottom plate and a peripheral wall rising from the outer edge of the bottom plate, and a draining device attached to the upper end of the peripheral wall, wherein the draining device has a mounting portion attached to the upper end of the peripheral wall of the container, and a mounting plate attached to the mounting portion so as to be movable in parallel between a lower limit position and an upper limit position. [Effects of the Invention]
[0008] According to the draining device and container with tray described above, water can be immediately drained from an article after it has been removed from the container. [Brief explanation of the drawing]
[0009] [Figure 1] Figure 1 is a schematic perspective view of a container with a tray according to an embodiment. [Figure 2] Figure 2 is a schematic cross-sectional view of the drainage device according to the embodiment, in a vertical cross-section. [Figure 3] Figure 3 is a schematic cross-sectional view of the tray-equipped container according to the embodiment in a folded state. [Figure 4] Figure 4 is a schematic perspective view illustrating an example of how to use a container with a tray according to the embodiment. [Modes for carrying out the invention]
[0010] (Embodiment) The tray-equipped container 1 according to this embodiment will now be described in detail. As shown in Figure 1, the tray-equipped container 1 according to this embodiment comprises a container 2 made of synthetic resin having a peripheral wall 22, and a draining device 3 attached to the upper end of the peripheral wall 22. The tray-equipped container 1 according to this embodiment has a handle 26 attached to the container 2, but the handle 26 is optional.
[0011] (container 2) The container 2 in this embodiment is a bucket. Referring to Figure 1, the container 2 is formed in a bottomed cylindrical shape with a bottom plate 21 and a peripheral wall 22 rising from the outer edge of the bottom plate 21, and having an opening on its upper surface. The container 2 is foldable. The container 2 is not limited to a bucket, but may be, for example, a basket, a tub, a washbasin, etc. Also, the container 2 may be box-shaped.
[0012] The peripheral wall 22 is tapered so that its diameter increases as it extends upward. In the peripheral wall 22, the cylindrical base portion 23, body portion 24, and neck portion 25 are continuous in this order. The body portion 24 consists of multiple cylindrical bodies 241 and 242 connected concentrically. In this embodiment, the multiple cylindrical bodies 241 and 242 include a first cylindrical body 241 and a second cylindrical body 242. The connection portions between the base portion 23 and the first cylindrical body 241, the first cylindrical body 241 and the second cylindrical body 242, and the second cylindrical body 242 and the neck portion 25 are all bendable so that the outer surface forms a valley. In addition, each of the cylindrical bodies 241 and 242 is bendable at the intermediate portion in the direction of the central axis so that the outer surface forms a peak. As a result, the body portion 24 is configured to be foldable, as shown in Figure 3.
[0013] In the container 2 in a folded state (sometimes referred to as "container 2 in a folded state"), the base portion 23, the first cylindrical body 241, and the second cylindrical body 242 are arranged concentrically inside the neck portion 25. In the container 2 in a folded state, the upper end of the neck portion 25 (i.e., the upper end of the peripheral wall 22) is positioned higher than the upper end of the folded body portion 24.
[0014] Container 2 is made of synthetic resin. Thermoplastic resin may be used as the synthetic resin forming the bottom, hem 23 and neck 25. Examples of thermoplastic resins include general-purpose plastics such as polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polystyrene, and ABS resin. The thermoplastic resin is not limited to general-purpose plastics; engineering plastics such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polycarbonate (PC) may also be used. Examples of materials for the body 24 include soft resin, thermoplastic elastomer, and thermosetting elastomer. In this disclosure, when referring to "container 2 formed from thermoplastic resin," it means that the majority is formed from thermoplastic resin, but it may also contain some materials other than thermoplastic resin (e.g., thermosetting materials, metals).
[0015] A handle 26 is attached to the neck portion 25. The handle 26 is rotatably mounted to the neck portion 25. The axis of rotation of the handle 26 is coaxial with the diameter of the neck portion 25. When the handle 26 rotates to a position along the upper end surface of the neck portion 25, the outer periphery plate 41 of the draining device 3, described later, is positioned between the handle 26 and the neck portion 25. In this embodiment, the handle 26 is made of synthetic resin. The synthetic resin forming the handle 26 can be the same material as that used for the container 2. However, unlike the synthetic resin container 2, the handle 26 may be made of metal. Also, the handle 26 does not need to be rigid and may be formed from a string.
[0016] (Drainage device 3) Referring to Figure 1, the draining device 3 comprises a mounting portion 4 and a mounting plate 5. The draining device 3 can be removably attached to the upper end of the peripheral wall 22 of the container 2. Therefore, the draining device 3 according to this embodiment can be attached to a container 2 owned by the user, or it can be sold as a set with the container 1 with the tray attached to the container 2.
[0017] (Mounting portion 4) The mounting portion 4 is a portion that is attached to the upper end of the peripheral wall 22 of the container 2 in the draining device 3. However, the mounting portion 4 may be attached to the peripheral wall 22 of the container 2 in a non-removable manner. In that case, the attachment of the mounting portion 4 to the peripheral wall 22 may include, for example, welding, brazing, integral molding, riveting, etc. The mounting portion 4 is formed in a shape that follows the upper end of the peripheral wall 22 when looking downward at the container 1 with a tray (hereinafter, in plan view), and in the present embodiment, it is formed in a substantially C shape. As shown in FIG. 2, the mounting portion 4 includes an outer peripheral plate 41, a top plate 42, and an inner peripheral plate 43. The mounting portion 4 is formed in a substantially U-shaped cross section.
[0018] The outer peripheral plate 41 faces the outer surface of the peripheral wall 22 in the container 2. As shown in FIG. 1, a plurality of outer peripheral plates 41 of the present embodiment are arranged at regular intervals along the circumferential direction centered on the central axis of the container 2. However, the draining device 3 may have only one outer peripheral plate 41 extending along the peripheral wall 22.
[0019] At least a part of the outer peripheral plate 41 contacts the outer peripheral surface of the neck portion 25. As shown in FIG. 2, a protrusion protruding toward the outer surface of the peripheral wall 22 in the container 2 is formed at the lower end portion of the outer peripheral plate 41. The protrusion contacts the outer peripheral surface of the neck portion 25.
[0020] The top plate 42 protrudes horizontally from the upper end of the outer peripheral plate 41 toward the central axis of the container 2. The upper surface of the top plate 42 is parallel to the horizontal plane and is a flat surface. As a result, when storing the container 1 with a tray, the protrusion of the mounting portion 4 upward from the outer peripheral plate 41 is reduced, and it is less likely to require an extra storage space. In plan view, the top plate 42 is formed so as to overlap the peripheral wall 22 of the container 2. The top plate 42 is formed in a substantially C shape in plan view.
[0021] The inner peripheral plate 43 protrudes downward from the inner end of the top plate 42. The inner peripheral plate 43 is continuous in the circumferential direction. The inner peripheral plate 43 is arranged to face the inner surface of the peripheral wall 22. The inner peripheral plate 43 has a plurality (three in this embodiment) of guide grooves 431. The guide grooves 431 open at least to the inside of the container 2. The guide grooves 431 are formed at positions overlapping the peripheral wall 22 when viewed from the container 2. Examples of the shape of the guide grooves 431 include a slit shape, an oval shape, and a rectangular shape. The longitudinal direction of the guide grooves 431 is parallel to the vertical direction. The outer peripheral surface of the mounting plate 5 faces the inner peripheral plate 43 (more specifically, the guide grooves 431).
[0022] The central angle between adjacent guide grooves 431 in the plurality of guide grooves 431 is preferably 30° or more and 90° or less, more preferably 35° or more and 75° or less. Each guide groove 431 extends in the vertical direction. As shown in FIG. 2, a plurality of protrusions 52 of the mounting plate 5 are inserted one-to-one into the plurality of guide grooves 431 from the inside to the outside of the container 2. The mounting plate 5 is supported by the inner peripheral plate 43 when the plurality of protrusions 52 fit into the plurality of guide grooves 431, and the vertical movement is guided by the guide grooves 431. That is, the plurality of guide grooves 431 can guide the vertical movement of the mounting plate 5.
[0023] The attachment portion 4 is made of synthetic resin. As the synthetic resin forming the attachment portion 4, a thermoplastic resin may be used. Examples of the thermoplastic resin include general-purpose plastics such as polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polystyrene, and ABS resin. The thermoplastic resin is not limited to general-purpose plastics, and for example, engineering plastics such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polycarbonate (PC) may be used.
[0024] (Mounting plate 5) The mounting plate 5 is a plate on which an article can be placed. In this embodiment, the mounting plate 5 is formed to fit within an area of less than half the opening surface of the container 2 in a plan view. As shown in Figure 2, the mounting plate 5 comprises a mounting plate body 51 having ribs 512 formed on its outer edge, and a plurality of protrusions 52 protruding from the ribs 512 of the mounting plate body 51.
[0025] The mounting plate body 51 constitutes the main body of the mounting plate 5. Referring to Figure 1, the outer edge of the mounting plate body 51 is formed by a curved portion 531 that follows the inner surface of the peripheral wall 22 of the container 2 in a plan view, and a straight portion 532 connecting both ends of the curved portion 531. In this embodiment, the mounting plate body 51 is formed in a shape surrounded by an arc as the curved portion 531 and a chord as the straight portion 532. However, the mounting plate body 51 is not limited to a shape surrounded by an arc and a chord, and may be formed in a fan shape or a rectangular shape in a plan view.
[0026] Referring to Figure 1, the mounting plate body 51 has a plurality of through holes 511. Each through hole 511 is an elongated hole extending in a direction perpendicular to the chord, which is the straight portion 532 of the mounting plate 5. In other words, the elongated holes in this embodiment extend parallel to the yaw height of the mounting plate body 51. Each through hole 511 extends from a position a predetermined distance away from the straight portion 532 to a position a predetermined distance away from the curved portion 531. The plurality of through holes 511 are formed at equal intervals in a direction parallel to the straight portion 532, with their longitudinal directions being parallel to each other. The "predetermined distance" here is preferably a distance shorter than the diameter of the through hole (width of the elongated hole). The predetermined distance is, for example, 2 mm or more and 10 mm or less, and more specifically, 4 mm or more and 8 mm or less.
[0027] Referring to Figure 2, the rib 512 protrudes downward from the outer peripheral edge of the mounting plate body 51. The rib 512 may be formed only along the curved portion 531 on the outer peripheral edge of the mounting plate body 51, or it may be formed along both the curved portion 531 and the straight portion 532. By being formed on the outer peripheral edge of the mounting plate body 51, the rib 512 constitutes the outer peripheral surface of the mounting plate body 51. When the rib 512 is formed along the curved portion 531 of the mounting plate body 51, the mounting plate body 51 and the inner peripheral plate 43 make planar contact, making it easier to achieve stable movement of the mounting plate 5. Also, when the rib 512 is formed along the straight portion 532, the bending of the mounting plate 5 caused by the object placed on it can be reduced.
[0028] Multiple protrusions 52 are arranged at intervals along the outer circumferential surface of the mounting plate body 51. The mounting plate 5 according to this embodiment has three protrusions 52 corresponding to the guide grooves 431. As described above, the multiple protrusions 52 are inserted one-to-one into the multiple guide grooves 431. As shown in Figure 2, each protrusion 52 is formed from a horizontal piece 521 extending from the lower end of the rib 512 to the outside of the peripheral wall 22 of the container 2, and a vertical piece 522 protruding downward from the outer tip of the horizontal piece 521. The multiple protrusions 52 are integrally formed with respect to the mounting plate body 51. The horizontal piece 521 passes through the opening of the guide groove 431. The vertical piece 522 is positioned between the inner circumferential plate 43 and the neck portion 25 of the container 2. The vertical piece 522 is positioned in close proximity to or in contact with the inner surface of the neck portion 25, thereby stabilizing the vertical movement of the mounting plate 5. Furthermore, the presence of the vertical piece 522 increases the contact area between the projection 52 and the inner surface of the container 2 compared to the case with the horizontal piece 521, thereby reducing the damage that may occur to the neck portion 25 when the projection 52 comes into contact with it.
[0029] Multiple projections 52 can move between their longitudinal upper and longitudinal lower ends in the corresponding guide grooves 431. This allows the mounting plate 5 to be mounted to the mounting portion 4 so that it can move parallel between an upper limit position and a lower limit position. The "lower limit position" refers to the position of the mounting plate 5 when the projections 52 are in contact with the lower end of the inner periphery of the guide groove 431. The "upper limit position" refers to the position of the mounting plate 5 when the projections 52 are in contact with the upper end of the inner periphery of the guide groove 431 or the lower surface of the top plate 42. In this embodiment, the upper surface of the mounting plate 5 at the upper limit position is located on the same plane as the upper surface of the top plate 42, as shown in Figure 2.
[0030] The mounting plate 5 is made of synthetic resin. A thermoplastic resin may be used as the synthetic resin forming the mounting plate 5. Examples of thermoplastic resins include general-purpose plastics such as polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polystyrene, and ABS resin. The thermoplastic resin is not limited to general-purpose plastics; engineering plastics such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polycarbonate (PC) may also be used. In this embodiment, the mounting plate 5 is made of the same material as the mounting portion 4.
[0031] With this configuration, for example, items washed in container 2 can be placed immediately on the mounting plate 5. This allows for immediate draining of water from items that have been washed and immersed in water in container 2. At this time, the mounting plate 5 is positioned at the lower limit, and the inner peripheral plate 43 of the mounting portion 4 rises from the mounting plate 5, thus reducing the risk of items placed on the mounting plate 5 falling out of container 2. Furthermore, when container 2 is folded, as shown in Figure 3, the mounting plate 5 rests on the upper end of the folded body portion 24 and is pushed up by the upper end of the body portion 24, moving above the lower limit position. Therefore, with the tray-equipped container 1 of this embodiment, container 2 can be folded without removing the draining device 3.
[0032] Referring to Figure 4, with the container 1 with a tray, after washing items using container 2, the water can be drained simply by tilting container 2. The water in container 2 is discharged through the through-hole 511 of the support plate 5, but the items are held back by the support plate 5. Therefore, it is possible to drain the water while keeping the items in container 2 inside.
[0033] (modified version) The above embodiments are merely one of many embodiments of this disclosure. The embodiments can be modified in various ways depending on the design, etc., as long as they achieve the objectives of this disclosure. The following lists some modifications of the embodiments. The modifications described below can be combined and applied as appropriate.
[0034] The draining device 3 according to the above embodiment was attached to a foldable bucket, but it may also be attached to a non-foldable bucket.
[0035] In the drainage device 3 according to the above embodiment, the projection 52 of the mounting plate 5 is inserted into the guide groove 431 of the mounting portion 4. However, a groove formed in the mounting plate 5 may be slidably inserted into a vertically extending projection formed on the mounting portion 4.
[0036] The drainage device 3 according to the above embodiment is equipped with a mounting plate 5 having three protrusions 52, but if the angle of the mounting plate body 51 can be maintained with respect to the inner peripheral plate 43 at the mounting portion 4, then there may be only one protrusion 52.
[0037] In the above embodiment, the mounting plate 5 is formed to correspond to approximately half of the area of the opening surface of the container 2, but it may also be formed to correspond to one-quarter of the area of the opening surface. Furthermore, the mounting plate 5 may be attached to the outer peripheral plate 41 of the mounting portion 4 so as to be movable in the vertical direction.
[0038] Although the mounting plate 5 according to the above embodiment has a plurality of through holes 511 formed therein, the through holes 511 do not necessarily have to be formed. For example, even if the mounting plate 5 does not have through holes 511 formed therein, water can be drained from the item placed on the mounting plate 5 by forming drainage grooves.
[0039] The body 24 of the container 2 was formed from two cylindrical bodies, a first cylindrical body 241 and a second cylindrical body 242, but it may have three or more cylindrical bodies.
[0040] In the above embodiment, the projection 52 is provided on a rib 512 formed on the outer edge of the mounting plate body 51. However, the mounting plate body 51 does not have to have a rib 512, and even if it has a rib 512, the projection does not have to protrude from the rib 512.
[0041] Although the container 2 in the above embodiment was made of synthetic resin, it does not necessarily have to be made of synthetic resin; it may be made of metal or glass. The synthetic resin used to form the container 2 is not limited to thermoplastic resins, but may also be a thermosetting resin.
[0042] In the above embodiment, the draining device 3 had both the mounting part 4 and the mounting plate 5 made of synthetic resin, but one of them may be made of synthetic resin only. For example, the draining device 3 may consist of a mounting part 4 made of synthetic resin and a mounting plate 5 made of metal, or it may consist of a mounting part 4 made of metal and a mounting plate 5 made of synthetic resin. Alternatively, it may consist of a container 2 made of synthetic resin and a draining device 3 made of metal.
[0043] (summary) As described above, the draining device 3 according to the first embodiment comprises a mounting portion 4 attached to the upper end of the peripheral wall 22 of the container 2, and a mounting plate 5 attached to the mounting portion 4 so as to be movable in parallel between a lower limit position and an upper limit position, wherein at least one of the mounting portion 4 and the mounting plate 5 is made of synthetic resin.
[0044] According to this embodiment, since an item can be placed on the mounting plate 5 of the draining device 3 attached to the peripheral wall 22, water can be immediately drained from the item after it is removed from the container 2. Also, since the mounting plate 5 moves in parallel, even if the draining device 3 is attached to a foldable container 2, the container 2 can be folded without removing the draining device 3. Since at least one of the mounting part 4 and the mounting plate 5 is made of synthetic resin, it is relatively easy to reduce the weight and it is less likely to damage the container 2 or the item placed on it.

According to this embodiment, smooth movement of the mounting plate 5 is easily achieved and stable movement is easily achieved.
[0048] In the fifth embodiment of the draining device 3, in the fourth embodiment, each projection 52 includes a horizontal piece 521 that protrudes outward from the outer peripheral surface of the mounting plate body 51 in a plan view and passes through the opening of the guide groove 431, and a vertical piece 522 that protrudes downward from the tip of the horizontal piece 521. According to this embodiment, the vertical piece 522 can be made to follow the inner surface of the peripheral wall 22 of the container 2, making it easier to achieve smoother movement on the mounting plate 5 and to achieve stable movement.
[0049] The sixth embodiment of the tray-equipped container 1 comprises a synthetic resin container 2 having a bottom plate 21 and a peripheral wall 22 rising from the outer edge of the bottom plate 21, and a draining device 3 attached to the upper end of the peripheral wall 22. The draining device 3 has a mounting portion 4 attached to the upper end of the peripheral wall 22 of the container 2, and a mounting plate 5 attached to the mounting portion 4 so as to be movable in parallel between a lower limit position and an upper limit position. According to this embodiment, since an article can be placed on the mounting plate 5 of the draining device 3 attached to the peripheral wall 22, water can be immediately drained from the article after it is removed from the container 2.
[0050] In the seventh embodiment, the tray-equipped container 1 is such that, in the sixth embodiment, at least one of the mounting portion 4 and the mounting plate 5 is made of synthetic resin. According to this embodiment, since at least one of the mounting portion 4 and the mounting plate 5 is made of synthetic resin, it is relatively easy to reduce the weight and less likely to damage the container 2 or the items placed on it.
[0051] In the eighth embodiment, the tray-equipped container 1 is a foldable container in the seventh embodiment, in which the peripheral wall 22 is foldable. According to this embodiment, the tray-equipped container 1 can be made more portable and easier to store. [Explanation of symbols]
