Description

The present invention is a free-standing system in which water can be hygienically drained while the opening is tilted downward without the edge of the cup opening touching anything, and the dripping water naturally flows into the sink drain. It's about cups.

Conventionally, cups used in wash basins, etc. are often stored with the opening facing upwards after use, which causes water droplets that adhere to the inside of the cup to accumulate on the bottom of the cup, leading to the growth of bacteria. There was a risk that dust or the like would inadvertently get into the cup. On the other hand, even if the cup is stored with its opening facing downwards, the edge of the cup's opening will come into contact with a sink or the like, so there is a risk of contamination with germs, which poses a sanitary problem in either case.

As a solution to this problem, a free-standing cup is known that can drain water hygienically with the opening tilted downward without the edge of the opening touching anything (for example, Patent Document 1, (see 2). In addition, even if you store an existing cup facing downwards, you can drain the water while avoiding contact with the edges of the cup opening as much as possible, and allow the dripping water to flow naturally into the drain of the sink tank. A draining cup stand is known (for example, see Patent Document 3).

The free-standing draining cup described in Patent Document 1 is composed of a cup body and a handle, and when the cup is placed with the handle facing down, the handle has a shape that can stably support the cup body. Moreover, the opening of the cup body is formed to face diagonally downward. Therefore, by changing the cup and placing the cup with the handle facing down, the water adhering to the inside of the cup body will drip downward from the lower end of the opening of the cup body.

The self-supporting inverted cup described in Patent Document 2 is composed of a cup body, a handle, and an inverted foot. The shape of the standing leg is such that the opening of the cup body stands on its own with the opening facing downward. Therefore, by placing the cup while holding the handle, water adhering to the inside of the cup body will drip downward from the lower end of the opening of the cup body.

The drainer cup stand described in Patent Document 3 is composed of a drainer cup stand main body, a convex part, a water stopper outer peripheral part, and a support section, and a support section for giving an inclination angle to the upper part of the back surface of the drainer cup stand main body is provided. As a result, the surface of the drainer cup stand becomes an inclined surface, and parallel convex portions are formed on the surface of the drainer cup stand for placing the cup, and a drain hole is formed on the outer periphery of the drainer cup stand. A water stopper outer periphery is formed. Then, the draining cup stand is fixed with a suction cup provided at the lower part of the column so that the drain port is located inside the edge of the basin of the washbasin. By placing an existing cup facing down on the convex surface of the drainer cup stand, the water that drips from the cup will naturally flow down from the drain outlet of the drainer cup stand into the basin of the washbasin instead of pooling. become.

Incidentally, the free-standing drainer cup described in Patent Document 1 and the free-standing inverted cup described in Patent Document 2 both have a mechanism for installing the cup body so that the lower end of the opening is located inside the edge of the basin of the washbasin. As a result, water that drips from the bottom of the opening of the cup body may form a puddle on the dry area around the tank or on the mounting surface such as the top plate, or the cup itself may slip into the tank. There is a possibility that an unfavorable situation may occur in terms of appearance or hygiene.

On the other hand, the drainer cup stand described in Patent Document 3 makes it possible to reliably drain the water dripping from the cup into the basin of the washbasin, but it requires the effort and effort to install the drainer cup stand in an appropriate position in advance. This is necessary, and since the opening edge of the cup comes into contact, albeit slightly, with the convex portion formed on the surface of the draining cup stand, there remains a risk that germs may adhere to the opening edge of the cup, which is undesirable from a sanitary standpoint.

As a result of intensive studies to solve these problems, the applicant of the present application came up with a structure that has a support part that supports the cup on the mounting surface and a protrusion that locks the cup to the edge of the tank, and developed a special structure. Application No. 2021-079735 proposes various specific structures.

Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. 1 to 13 are diagrams illustrating embodiments of the present invention. In these diagrams, parts with the same reference numerals represent the same parts, and the basic configuration and operation are the same. .

Example 1 will be described using FIGS. 1 to 5.
FIG. 1 is a perspective view of a draining cup according to Example 1 of the present invention.
FIG. 2 is a sectional view taken along the line AA in FIG. 1 of the colander according to the first embodiment of the present invention.
A drainer cup 1 shown in FIG. 1 is composed of a cup body 2, a protrusion 3, and a support structure 4.

The cup body 2 has a substantially inverted truncated cone shape and is composed of a side surface 21, a bottom surface portion 22, and an opening 23.
The side surface 21 has an outer circumferential surface 211 and an inner circumferential surface 212. A circular bottom portion 22 with a small diameter is provided on the rear surface of the side surface 21, and a circular bottom portion 22 with a larger diameter than the bottom portion 22 is provided on the front surface of the side surface 21. A shaped opening 23 is opened. The projecting piece 3 and the support structure 4 are fixed to the lower side of the outer circumferential surface 211.
In the case of this embodiment, as shown in FIG. 2, when the cup body 2 is placed on the placement surface 611, the lower side of the inner peripheral surface 212 is configured to tilt downward from the bottom surface portion 22 toward the opening 23. has been done.

FIG. 3 is a rear view of the draining cup according to Example 1 of the present invention.
As shown in FIG. 3, the projecting piece 3 is located directly below the outer circumferential surface 211, has a substantially U-shape when viewed from the back, and extends diagonally forward away from the outer circumferential surface 211 as shown in FIG. It extends and is formed so that it becomes rounder as it goes from the thick root to the tip.
As shown in FIG. 2, the tip of the protruding piece 3 is located behind the opening 23 on the front surface.
Because of this shape and arrangement, when the draining cup 1 is placed on the edge of the tank 61, the back of the protruding piece 3 touches the inside of the edge of the tank 61, and the draining cup 1 cannot be pulled any further backward. , the opening 23 is reliably located inside the tank 61. That is, the protruding piece 3 functions as a stopper that locks the colander 1 to the edge of the tank 61.

FIG. 4 is a bottom view of the draining cup according to Example 1 of the present invention.
The support structure 4 includes a first support part 41 and a second support part 42. The first support part 41 and the second support part 42 are arranged on the outer circumferential surface 211 so that their centers or centers are aligned with the projecting piece 3 in the front and rear.
The first support portion 41 is located immediately on the back side of the protruding piece 3, and as shown in FIG. 3, is lower than the protruding piece 3, has a substantially hemispherical shape, and is fixed to the outer circumferential surface 211.
As shown in FIG. 2, the first support portion 41 is provided in the tub 61 to prevent the draining cup 1 from slipping into the tub 61 when the draining cup 1 is locked to the edge of the tub 61 by the back surface of the protruding piece 3. It serves as a locking leg that locks on the edge.

As shown in FIG. 3, the second support part 42 has two support legs provided at symmetrical angles in the circumferential direction with respect to the position of the first support part 41 (directly below the outer circumferential surface 211), and each has a tapered shape. As shown in FIG. 4, it is fixed to the outer circumferential surface 211 in the vicinity of the bottom surface section 22 at the rear of the first support section 41. As shown in FIG.
As shown in FIG. 2, the support legs of the second support part 42 are such that when the colander 1 is placed on the edge of the tank 61, the opening 23 and the bottom part 22 of the cup body 2 are perpendicular to the placement surface 611. The height is set so that the draining cup 1 can be stably supported on the mounting surface without falling over.

By adopting such a configuration, as shown in FIG. 2, when the colander 1 is placed on the edge of the tank 61, the lower side of the inner peripheral surface 212 faces from the bottom part 22 to the opening 23, and the bottom part 22 and Since the opening 23 is tilted downward by an angle corresponding to half the difference in diameter, water droplets adhering to the inner circumferential surface 212 naturally drip into the tank 61.

In the case of this embodiment, the cup body 2 is used for rinsing the mouth after brushing teeth and gargling for sterilizing the oral cavity, so from the viewpoint of ease of use, the cup body 2 generally has an opening diameter of 5.5 cm to 10 cm and a height of 5.5 cm to 10 cm. Preferably, the opening diameter is 7 cm to 8 cm, the height is 6 cm to 7 cm, and the bottom diameter is 4 cm to 5 cm.
Therefore, the slope of the lower side of the inner circumferential surface 212 is 6° to 22.5°, more preferably 9° to 15°.

From the viewpoint of reliably locking the colander 1 to the edge of the tank 61, the protruding piece 3 may have a height of 0.5 cm to 1.5 cm, more preferably 0.8 cm to 1.2 cm. Further, the width of the protruding piece 3 may be 1 cm to 3 cm, more preferably 1.5 cm to 2.5 cm.
Further, the protruding piece 3 is arranged at an angle of 10° to 30° with respect to the vertical surface of the tank 61 shown in FIG. It is desirable that the angle is tilted diagonally forward, more preferably from 15° to 25°.

The first support part 41 of the support structure 4 has a radius of 0.4 cm from the viewpoint of reliably locking the colander 1 to the mounting surface 611 without slipping down into the tank 61 while also considering the height of the protrusion 3. ~0.8 cm is sufficient, and more preferably 0.5 cm ~ 0.6 cm.

The height of the second support part 42 is determined by considering the shapes of the cup body 2 and the first support part 41, but from the viewpoint of stable support, it is preferably about 0.5 cm to 3 cm, more preferably 1 cm to 3 cm. It is 1.5 cm. Further, the angle between the two second support parts 42 is preferably 60° to 120°, more preferably around 90°.

The material for the drainer cup 1 is mainly made of inexpensive general-purpose thermoplastic resins such as AS resin, ABS resin, acrylic resin, and methacrylic resin from the viewpoint of price, and is integrally formed by injection molding for ease of processing. Often processed.
Since general-purpose resins are generally hydrophobic, water droplets adhering to the inner circumferential surface 212 can be sufficiently dripped down with the above-mentioned inclination.
The color of the material can be transparent, translucent, or opaque depending on the type of resin, but it can be colored in various colors by mixing pigments.
Note that the shape of the bottom portion 22 and the opening 23 of the cup body 2 is not limited to a circle, but may be an ellipse, a triangle, a square, a polygon, or the like.

Next, an example of how to use the draining cup 1 of the first embodiment configured as described above will be described with reference to FIG. 5.

FIG. 5 is a diagram showing an example of how to use the draining cup according to the first embodiment of the present invention.
FIG. 5(A) shows an example in which the colander 1 is placed on the edge of the tank 61 of the washstand 6 and stored.
As shown in FIG. 5(A), after using the drainer cup 1, by placing it on the edge of the tank 61 and storing it, the water droplets attached to the inner peripheral surface 212 of the drainer cup 1 will naturally flow inside the tank 61. The water drips down and flows into the drain port 612.

FIG. 5(B) enlarges the vicinity of the edge of the tank 61 in FIG. 5(A) and specifically shows the procedure for placing the draining cup 1 thereon.
After using the drainer cup 1 by grasping the outer circumferential surface 211 with the palm of the hand, if you pull the palm back from the inside of the tank 61 toward the edge without changing the grip, the drainer cup 1 can be moved into the tank by the back surface of the protrusion 3. 61 , and the support structure 4 (first support part 41 and second support part 42 ) is placed on the placement surface 611 .

Since the opening 23 of the draining cup 1 is located in front of the protruding piece 3, that is, above the inside of the tank 61, water droplets will not drip onto the mounting surface 611 to form a puddle.

As described above, according to the first embodiment of the present invention, by adopting the above structure, the structure is simple, easy to manufacture, easy to use and hygienic, and the water dripping from the cup is naturally drained into the sink. It is possible to provide a colander that drains into the tank.

Next, a drainer cup according to a second embodiment of the present invention will be described using FIGS. 6 to 9.
Note that the basic configuration and functions of the draining cup of Example 2 are the same as those of Example 1, and therefore, description thereof will be omitted.

FIG. 6 is a perspective view of a draining cup according to Example 2 of the present invention.
FIG. 7 is a sectional view taken along line AA in FIG. 6 of a draining cup according to Example 2 of the present invention.
FIG. 8 is a rear view of a draining cup according to Example 2 of the present invention.
The draining cup 1 of Example 2 differs in structure from Example 1 in that it has a handle 5 on the upper side of the outer circumferential surface 211.

In the draining cup 1 of the second embodiment, the handle 5, which is approximately U-shaped when viewed from the side as shown in FIG. As shown in FIG. 7, it is fixed slightly behind the projecting piece 3.
This is done in consideration of the center of gravity so that the draining cup 1 is locked to the edge of the tank 61 and does not slip into the tank 61 when placed on the mounting surface 611.
From the viewpoint of the shape of the cup body 2 and ease of use, the handle 5 preferably has a width of 1 cm to 1.5 cm and a length of 4.5 cm to 8 cm, more preferably a width of about 1 cm and a length of about 5 cm.

FIG. 9 is a diagram showing an example of how to use the draining cup according to the second embodiment of the present invention.
Next, a method of using the draining cup 1 configured as described above will be explained using FIG. 9.

FIG. 9(A) is a perspective view of an example in which the colander 1 is placed on the edge of the tank 61 of the washstand 6 and stored.
As shown in FIG. 9(A), after using the draining cup 1, by placing it on the mounting surface 611 on the edge of the tank 61 and storing it, water droplets attached to the inner circumferential surface 212 of the draining cup 1 are removed. It naturally drips inside the tank 61 and flows into the drain port 612.

FIG. 9(B) is an enlarged side view of the edge of the tank 61 in FIG. 9(A), showing a specific procedure for placing the draining cup 1 thereon.
In the first embodiment, since the outer circumferential surface 211 of the colander 1 was held directly in the palm of the hand, it was necessary to adjust the position with the wrist in order to install the two second supports 42 on the placement surface 611. However, by providing the handle 5 directly above the outer circumferential surface 211 in this way, after using the drainer cup 1 by holding the handle 5, it is possible to attach the drainer cup 1 to the edge from the inside of the tank 61 without changing the grip. When the handle 5 is pulled back to stop the handle 5, the protrusion 3 and the support structure 4 are located directly below the handle 5, so that they are naturally locked by the back surface of the protrusion 3 of the draining cup 1, and the first support part 41 Both of the second support parts 42 are naturally placed on the placement surface 611.

As described above, according to the second embodiment of the present invention, by adopting the above configuration, after using the cup while holding the handle 5, the handle 5 can be moved backward from the inside of the tank toward the edge without changing the grip. When pulled, the draining cup 1 is naturally locked to the edge of the tank 61 by the back surface of the projecting piece 3, and the support structure 4 (first support part 41 and second support part 42) is placed on the placement surface 611. Therefore, it is possible to provide a draining cup that allows water droplets adhering to the inner circumferential surface 212 of the cup body 2 to naturally drip down from the opening 23 into the tank 61.

Next, a drainer cup according to Example 3 of the present invention will be described using FIGS. 10 to 12.
Note that the basic configuration and functions of the draining cup of Example 3 are the same as those of Example 1, so a description thereof will be omitted.

FIG. 10 is a side view of a draining cup according to Example 3 of the present invention.
FIG. 11 is a bottom view of a draining cup according to Example 3 of the present invention.
The draining cup 1 of the third embodiment differs in structure from the second embodiment in that it has a handle 5 on the side of the outer circumferential surface 211.

As shown in FIG. 10, in the draining cup 1 of Example 3, the handle 5, which is substantially U-shaped when viewed from the side, is located directly beside the outer circumferential surface 211, that is, at the position of the protruding piece 3 (directly below the outer circumferential surface 211). ) is fixed at a position rotated by 90° in the circumferential direction with reference to the projection piece 3, as in the second embodiment.
As shown in FIG. 11, two handles 5 are formed to project symmetrically from both sides of the outer circumferential surface 211.
When viewed from the bottom, the handle 5 on the left side is used when the handle is in the left hand, and the handle 5 on the right side is used when the handle is in the right hand. It is also possible to have only one handle 5.

FIG. 12 is a diagram showing an example of how to use the draining cup according to the third embodiment of the present invention.
Next, a method of using the drainer cup 1 configured as described above will be explained using FIG. 12.
FIG. 12(A) is a perspective view of an example in which the draining cup 1 is placed on the edge of the tank 61 of the washstand 6 and stored.
FIG. 12(B) is an enlarged side view of the edge of the tank 61 shown in FIG. 12(A), showing a specific procedure for placing the draining cup 1 thereon.
In the second embodiment, it was sufficient to hold the handle 5 provided directly above the outer circumferential surface 211 from above and pull the handle 5 backward from the inside of the tank 61 toward the edge, but in this embodiment, for example, with the left hand After using the colander 1 by holding the handle 5, just pull the handle 5 to the left side from the inside of the tank 61 toward the edge.

As described above, according to the third embodiment of the present invention, by adopting the above configuration, after using the cup by holding the handle 5, as in the case of the second embodiment, it is possible to open the cup from the inside of the tank 61 without changing the grip. When the handle 5 is pulled to the left toward the edge, the draining cup 1 is naturally locked to the edge of the tank 61 by the back surface of the protruding piece 3, and the support structure 4 (the first support part 41 and the second support part 42 ) is placed on the placement surface 611, so the draining cup is designed with consideration to design that allows water droplets attached to the inner circumferential surface 212 of the cup body 2 to naturally drip from the opening 23 into the tank 61. can be provided.

Finally, a drainer cup according to Example 4 of the present invention will be described using FIG. 13.
Note that the basic configuration and functions of the draining cup of Example 4 are the same as those of Example 1, and therefore the description thereof will be omitted.

FIG. 13 is a side view of a draining cup according to Example 4 of the present invention.
Since the projecting piece 3 is formed to extend obliquely forward, it can be reliably locked even when the edge of the tank 61 is obliquely inclined.
In the draining cup 1 of the fourth embodiment, the center of the opening 23 is shifted downward from the center of the bottom part 22, and the upper side of the side surface 21 becomes flat from the bottom part 22 toward the opening 23, and the lower part of the side surface 21 becomes flat. There is a difference in configuration from Example 2 in that the slope from the side bottom surface portion 22 toward the opening 23 is increased.
By adopting the above configuration, when the draining cup 1 is placed on the edge of the tank 61, the water droplets attached to the inner circumferential surface 212 of the cup body 2 drip more quickly due to the increased slope of the lower side of the side surface 21. It's going to fall.

Although the draining cup according to the embodiment of the present invention has been described above by showing specific embodiments, the present invention is not limited thereto. Those skilled in the art can make various changes and improvements to the structure and function of the invention according to the above embodiments or other embodiments without departing from the gist of the invention.

For example, according to the embodiment of the present invention, the draining cup 1 has been described in which the handle 5 is provided on the upper side or on the side of the outer circumferential surface 211. You can often achieve a similar effect in terms of design as well.
