Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid for a bathroom container installed in a bathroom, such as a detergent tank of a bathtub cleaning device, and a bathroom container having the same.

The present applicant has previously proposed a detergent tank described in Patent Document 1 as an example of a container installed in a bathroom.
The detergent tank described in the same document is shown in FIG. 5 of the present application. The detergent tank Ae includes a detergent tank main body 1e (container main body) having a mouth/neck portion 10e, and a lid 2e attached to the mouth/neck portion 10e via an auxiliary member 3e.

Such a detergent tank Ae is used, for example, in a state in which the lower part of the detergent tank Ae is branched and connected to the hot water supply path of the bathtub cleaning device through an appropriate piping member. The hot water supply path is a path for supplying detergent and hot water to the bathtub cleaning nozzle. It is possible to jet this mixed water (detergent water) from the washing nozzle toward the bathtub. When the detergent flows out from the detergent tank Ae toward the hot water supply path, a negative pressure is generated inside the detergent tank Ae. Therefore, in order to smoothly flow out the detergent from the detergent tank Ae, the detergent tank Ae needs to be air-permeable to the outside.

Therefore, in Patent Document 1, the lid 2e is provided with ventilation means. The lid 2e has a downward convex cylindrical wall portion 22e protruding from the rear surface of the lid main body portion 20e, and a downward peripheral wall portion 29e connected to the outer peripheral edge portion. The cylindrical wall portion 22e is externally fitted and screwed to the auxiliary member 3e. As a ventilation means, a concave groove-shaped first notch portion 9a formed on the back surface of the lid main body portion 20e and a cylindrical wall portion communicating with the first notch portion 9a at the upper portion are provided. 22e has a groove-shaped second notch 9b formed to extend in the vertical height direction. The second notch 9b has a lower end opening 90 that opens downward.
According to such a configuration, it is possible to provide air permeability through the first and second cutouts 9a and 9b, so that the detergent can smoothly flow out of the detergent tank Ae. The downward peripheral wall portion 29e of the lid main body portion 20e serves to prevent shower water used in a bathroom from directly splashing on the lower end opening portion 90 of the second notch portion 9b.

However, the prior art still has room for improvement as described below.

That is, the first notch portion 9a is a concave groove provided on the back surface of the lid main body portion 20e, and the second notch portion 9b is provided on the inner circumference of the cylindrical wall portion 22e of the lid 2e. It is difficult to form these with a large opening area because they are recessed grooves. Therefore, when a negative pressure is generated in the detergent tank Ae, the flow velocity of air passing through the first and second cutouts 9a and 9b increases. As a result, if water such as residual shower water exists in the vicinity of the lower end opening 90 of the second notch 9b, this water is drawn into the second notch 9b by the fast air flow. There is a risk that the detergent will be removed and flow into the detergent tank Ae. If such a phenomenon occurs, the water will be mixed with the detergent in the detergent tank Ae, which is not preferable.
Further, in the conventional technology, the downward peripheral wall portion 29e of the lid main body portion 20e surrounds the entire periphery of the cylindrical wall portion 22e, and when water enters inside the peripheral wall portion 29e, the water Due to surface tension, it becomes difficult to discharge to the outside of the peripheral wall portion 29e. Therefore, most of the water that has entered the inner side of the peripheral wall portion 29e is sucked into the second notch portion 9b, and there is a possibility that the phenomenon of water flowing into the detergent tank Ae will occur more easily.

JP-A-10-234599

The present invention has been conceived under the circumstances as described above, and it is possible to appropriately prevent or suppress the intrusion of water into the interior while appropriately ensuring breathability. An object of the present invention is to provide a lid for a bathroom-installed container and a bathroom-installed container having the same.

In order to solve the above problems, the present invention takes the following technical measures.

The lid of the container installed in the bathroom provided by the first aspect of the present invention is provided with a downwardly convex cylindrical wall portion on the back surface, and the cylindrical wall portion is connected to the mouth/neck portion of the container main body or the mouth of the container body. a lid main body that can be attached to the container main body in a state of being externally fitted to a cylindrical auxiliary member attached to the neck; and ventilation means for ventilating the inside of the container with the outside, wherein at least one lid is provided to penetrate the cylindrical wall portion in the thickness direction as the ventilation means. an outer wall portion having a vent, projecting downward from the lid body portion and facing the entire area of the vent in a spaced apart manner outside the tubular wall portion; The portion is formed as a wall portion that is discontinuous in the circumferential direction of the lid main body portion, and the gap between the outer wall portion and the cylindrical wall portion is formed from the outer side of the outer wall portion to the The gap communicates with the gap through the gap between the discontinuous walls so that air or water can enter the gap, and the width of the gap is close to the ventilation hole in a plan view. It is characterized in that it is formed so as to become narrower as the portion increases .

According to such a structure, the following effect can be obtained, in addition to the fact that the bathroom-installed container can be provided with air permeability by using the ventilation holes.
First, the ventilation hole is provided through the cylindrical wall portion of the lid in its thickness direction, and can have a relatively large area. Therefore, it is possible to stabilize the air intake from the outside into the bathroom installation container when the inside of the bathroom installation container becomes negative pressure, and it is also possible to slow down the flow velocity when the air passes through the ventilation hole. . As a result, when there is water such as residual water in the shower near the ventilation holes, the phenomenon of this water being sucked into the ventilation holes due to high-speed airflow and flowing into the bathroom-installed container is properly prevented. or can be suppressed.
Second, the vents can be covered with the outer wall so that even if water, such as shower water, splashes directly toward the lid, the water will flow directly to the location of the vents. It is possible to appropriately prevent such things as hanging and entering the inside. Therefore, even if the vent hole is provided with a relatively large area, it is possible to appropriately prevent or suppress water from entering the bathroom-installed container through the vent hole.

Furthermore, according to the above configuration, unlike the case where the outer wall portion is formed in a cylindrical shape that is continuous in the circumferential direction of the lid main body portion, the water that has entered the outer wall portion is pushed into the outer wall portion by its surface tension. It is possible to prevent it from being difficult to be discharged to the outside of the part. Therefore, it is possible to make it more difficult for water to enter the ventilation holes existing inside the outer wall portion, and by extension, to enter the bathroom-installed container.

Furthermore, according to the above configuration, as will be understood from the embodiment described later with reference to FIG. (including air containing a large amount of air) enters, the velocity of these flows increases as they approach the ventilation holes. In this case, the venturi effect can be expected to exert a negative pressure on the ventilation hole and cause the air to flow out from the ventilation hole toward the gap. As a result, it is possible to prevent water from entering the ventilation hole through the gap, thereby more reliably preventing or suppressing the improper entry of water into the bathroom-installed container.

In the present invention, preferably, in plan view, the tubular wall portion is cylindrical, and the surface of the outer wall portion facing the tubular wall portion is preferably the outer peripheral surface of the tubular wall portion. It is a planar shape extending in the tangential direction of

According to such a configuration, the configuration in which the width of the gap between the outer wall portion and the tubular wall portion becomes narrower toward the air hole can be appropriately realized with a simple configuration. In addition, the gap formed by the above configuration has the narrowest width near the ventilation hole in the center of the gap, and the width is wide at both ends. After passing through the narrow portion, it becomes easier to reach the other end side through the portion where the width gradually widens. Therefore, it is possible to obtain the effect of making it difficult for water to remain in the gap.

In the present invention, preferably, the outer wall portion protrudes downward from the outer peripheral edge portion of the lid body portion so as to be positioned outside the cylindrical wall portion, and is spaced apart in the circumferential direction of the lid body portion. A plurality of outer wall portions are provided in a row, and at least one of the plurality of outer wall portions is the outer wall portion facing the vent hole.

According to such a configuration, when gripping the lid by hand, fingers can be easily caught on the plurality of outer wall portions. Therefore, it becomes difficult for the hand to slip, and the usability can be improved.

In the present invention, it is preferable that an annular concave portion or a It further comprises an annular convex or concave sealing portion that can be fitted with the convex portion.

According to such a configuration, even if water enters the lower part of the gap formed between the mouth and neck portion or the auxiliary member and the cylindrical wall portion, the water will move the position of the seal portion. The presence of the sealing portion adequately prevents it from rising to the position of the vent hole. Therefore, it is possible to more reliably prevent water from entering the bathroom-installed container through the vent hole.

The bathroom-mounted container provided by the second aspect of the invention is characterized by comprising the lid of the bathroom-mounted container provided by the first aspect of the invention.

According to such a configuration, the same effect as described for the lid of the bathroom installation container provided by the first aspect of the present invention can be obtained.

Other features and advantages of the present invention will become clearer from the following description of embodiments of the invention with reference to the accompanying drawings.

It is the principal part sectional drawing of the bathroom installation container shown in FIG. 1, and its principal part expanded sectional view. (a) is a perspective view of the lid of the bathroom installation container shown in FIG. 1, (b) is a IIIb-IIIb cross-sectional view of (a), and (c) is a IIIc-IIIc cross-section of (a). It is a diagram. (a) is a perspective view of the back side of the lid of the container installed in the bathroom shown in FIG. 1, and (b) is a bottom view of the lid shown in (a) and an enlarged view of the essential part thereof. FIG. 2 is a cross-sectional view of a main part showing an example of conventional technology;

Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

The bathroom installation container A shown in FIGS. 1 and 2 is a detergent tank for containing a liquid detergent for bathroom cleaning and for supplying the detergent to a predetermined hot water supply path of a bathroom cleaning device (not shown). This bathroom installation container A comprises a container body 1, a lid 2, an auxiliary member 3, and an additional lid 5. - 特許庁These materials are all made of resin, but are not limited to this. In addition, the bathroom-installed container A is also provided with a packing 4 made of rubber or resin.

The additional lid 5 is attached to the container body 1 in a screwed manner so as to seal the opening 18 provided in the container body 1. From the opening 18 into the container body 1, A sensor (not shown) is inserted to detect the detergent liquid level. The additional lid 5 does not have air permeability and does not correspond to the lid of the bathroom installation container of the present invention (however, the present invention is applied to the additional lid 5 for the sensor to provide air permeability. configuration is also possible).
In FIG. 1, reference numeral 19 denotes an outflow pipe for detergent, and the detergent is supplied to a desired position through piping member 6 connected to this outflow pipe 19. As shown in FIG.

The container main body 1 is formed in a shape and size suitable for containing the detergent, and has an opening 10a for introducing detergent at the upper end and a mouth and neck having a threaded portion 10b on the outer peripheral surface. A part 10 is integrally formed. As will be described later, the lid 2 is attached to the mouth/neck portion 10 via the auxiliary member 3 .

The auxiliary member 3 has a substantially cylindrical shape with different diameters. An outer peripheral side stepped portion 30 having an outer diameter larger than that of other portions is formed on the outer peripheral surface of the upper portion of the auxiliary member 3, and the inner peripheral surface of the upper portion is formed with an inner peripheral side stepped portion 31 having an inner diameter smaller than that of other portions. A screw portion 32 is formed on the inner peripheral surface of the auxiliary member 3 below the inner peripheral side stepped portion 31 . The auxiliary member 3 is fitted onto the mouth/neck portion 10, and the screw portions 10b and 32 are screwed together.

As shown in FIGS. 3 and 4, the lid 2 includes a lid main body portion 20 in which a downward convex cylindrical wall portion 22 is provided on the back surface of a substantially disc-shaped top plate portion 21, and a lid main body portion 20 It has a plurality of outer wall portions 23 protruding downward from the outer peripheral edge portion of the outer wall portion 23, which are integrally molded. A plurality of vent holes 24 are provided in the tubular wall portion 22 .

The cylindrical wall portion 22 can be fitted onto the outer peripheral surface of the outer peripheral side stepped portion 30 of the auxiliary member 3, as shown in FIG. The inner peripheral surface of the cylindrical wall portion 22 is provided with an annular convex seal portion 25 that can be fitted (engaged) into an annular recessed portion 33 formed on the outer peripheral surface of the outer peripheral side stepped portion 30 . there is A waterproof seal is achieved by fitting the seal portion 25 and the concave portion 33 together. Preferably, the seal portion 25 is provided below the air hole 24, and even if water enters the gap between the lower end portion of the cylindrical wall portion 22 and the outer peripheral surface of the outer peripheral side stepped portion 30, , the entrance of water into the bathroom installation container A is prevented by the seal portion 25 .
In the present invention, contrary to the present embodiment, an annular convex portion may be formed on the outer peripheral side stepped portion 30, and the seal portion 25 may be formed in an annular concave shape that can be fitted into the convex portion. .

Ventilation hole 24 is provided through tubular wall portion 22 in its thickness direction, and has, for example, a substantially oval or rectangular shape having an appropriate length in the circumferential direction of tubular wall portion 22 . However, other forms such as round holes are also possible. In this embodiment, the ventilation holes 24 are provided at a total of two locations facing each other across the center of the tubular wall portion 22 . Further, as shown in the enlarged cross-sectional view of the main part of FIG. The outer peripheral edge is provided with a tapered portion 34 that is spaced apart from the portion where the vent hole 24 is formed.

As shown in FIG. 4, the plurality of outer wall portions 23 are spaced apart from the cylindrical wall portion 22 to the outside (radially outward) thereof, and are spaced apart in the circumferential direction of the lid body portion 20. They are arranged side by side and are non-cylindrical wall portions that are discontinuous in the circumferential direction. Two outer wall portions 23 ( 23 A) of the plurality of outer wall portions 23 face the ventilation hole 24 . An inner side surface 23 a of each outer wall portion 23 is planar and extends in a tangential direction of the outer peripheral surface of the tubular wall portion 22 . For this reason, as shown in the enlarged view of the essential part in FIG. gradually narrows. As will be described later, this configuration makes it difficult for water to enter the venturi 24 due to the venturi effect.

Next, an example of use and action of the above-described bathroom installation container A will be described.

As shown in FIG. 2, the bathroom installation container A is attached such that the container main body 1 is positioned below the bathtub flange 7, for example. Specifically, the bathtub flange 7 is provided with a hole 70 , and the auxiliary member 3 is inserted into the hole 70 so that the outer peripheral side stepped portion 30 of the upper portion is engaged with the upper surface of the bathtub flange 7 . ing. A packing 4 is interposed between the lower surface of the bathtub flange 7 and the container body 1 , and the bathtub flange 7 is sandwiched between the packing 4 and the outer step 30 . The piping member 6 connected to the outflow pipe 19 shown in FIG. The detergent in the installation container A flows into the hot water supply channel, and the detergent mixed with the hot water is jetted from the washing nozzle toward the bathtub.

When the detergent in the bathroom-installed container A flows out from the outflow pipe 19, a negative pressure is generated in the bathroom-installed container A, and external air flows into the bathroom-installed container A through the ventilation hole 24. - 特許庁Here, the ventilation hole 24 is provided through the cylindrical wall portion 22 of the lid 2, and can have a relatively large opening area. Therefore, ventilation through the ventilation holes 24 can be stabilized. Further, if the opening area of the vent hole 24 is increased, the flow velocity of the airflow passing through the vent hole 24 can be slowed down. Entry of water into the vent holes 24 is also prevented or suppressed.

An outer wall portion 23 is positioned outside the vent hole 24, and even if water such as shower water splashes toward the lid 2, the water does not directly splash on the vent hole 24. This is prevented by part 23. Therefore, it becomes more difficult for water to enter the vent hole 24, and even if the vent hole 24 is provided with a relatively large area, the water can improperly enter the bathroom installation container A through the vent hole 24. It is possible to appropriately prevent or suppress

Since the plurality of outer wall portions 23 are spaced apart from each other in the circumferential direction, it is possible to facilitate the drainage of water to the outside when water enters the inner side of the plurality of outer wall portions 23 . In other words, unlike the present embodiment, if the outer wall portion 23 were formed in a cylindrical shape that continued in the circumferential direction, the water that entered the inner side of the outer wall portion 23 would be exposed to the outside due to surface tension. It becomes difficult to flow out into the water, and water tends to remain. This makes it more likely that this residual water will enter the vent 24 . On the other hand, according to the configuration of the present embodiment, it is possible to obtain the effect of making such a phenomenon less likely to occur.

In the enlarged view of the main part of FIG. 4(b), a stream of water such as shower water flows into the gap C between the outer wall portion 23 and the tubular wall portion 22 as indicated by an arrow Na. In the case of entering from the above, the width La of the gap C becomes narrower as it approaches the ventilation hole 24, so the water flow becomes faster. Then, the venturi effect causes the air to flow out from the ventilation hole 24 toward the clearance C side. Therefore, it is possible to prevent the water flow from entering the ventilation hole 24 through the gap C. Further, when the water flow passes near the vent hole 24, the width La of the gap C gradually widens. Therefore, the water flow smoothly flows through the gap C and easily flows out from the other end side of the gap C to the outside. Therefore, an effect of making it difficult for water to remain in the gap C is also obtained.

A water stop seal is achieved by fitting the seal portion 25 and the annular concave portion 33 , and water is prevented from entering a small gap between the lower end portion of the cylindrical wall portion 22 and the outer peripheral surface of the outer peripheral side stepped portion 30 of the auxiliary member 3 . Even if water enters, the water is properly prevented from entering the inside of the bathroom-installed container A beyond the above-mentioned waterproof seal.

When opening and closing the lid 2 , the user grips the lid 2 by hand. Since the plurality of outer wall portions 23 are spaced apart from each other, such finger hooking can be easily and naturally performed, and the usability is also good.

The invention is not limited to the content of the embodiments described above. The lid of the bathroom-installed container according to the present invention and the specific configuration of each part of the bathroom-installed container can be varied in design in various ways within the intended scope of the present invention.

In the above-described embodiment, a total of two vent holes are provided in the cylindrical wall portion of the lid. Moreover, as described above, the shape of the ventilation hole is not limited, and the specific size thereof is not limited.

The outer wall portion of the lid in the present invention is originally provided to face the ventilation hole and prevents or suppresses the splashing of water on the ventilation hole. It is also possible to adopt a configuration in which an outer wall portion that does not face the vent hole is further provided. Of course, unlike this, it is also possible to adopt a configuration in which the outer wall portion that does not face the ventilation hole is not provided.

The tubular wall portion of the lid according to the present invention is not limited to a cylindrical shape, and can be changed in accordance with the shape of the portion to be externally fitted. For example, a non-cylindrical shape such as an elliptical cylindrical shape or a square cylindrical shape can be used.
In the above-described embodiment, the lid 2 is attached to the mouth/neck portion 10 of the container body 1 via the auxiliary member 3, but the present invention is not limited to this. As the auxiliary member, a structure different from that of the auxiliary member 3 described above can be used. In addition, by configuring the mouth/neck portion 10 of the container body 1 so that the cylindrical wall portion 22 of the lid 2 can be directly fitted, the auxiliary member 3 or another auxiliary member can be used. Instead, it is possible to adopt a configuration in which the lid 2 is directly attached to the mouth/neck portion 10 .

The bathroom installation container as used in the present invention means a container installed and used in a bathroom, and is not limited to a detergent tank. The type of substance contained in the bathroom-installed container is also not limited.
