JP7149964B2 - Cleaning set with drug holder and drug - Google Patents

Description

TECHNICAL FIELD The present invention relates to a medicine holder for setting a solid washing medicine in a flush toilet and a cleaning set including the medicine holder and the medicine.
This application claims priority to Japanese Patent Application No. 2018-9430 filed on January 24, 2018, and the contents thereof are incorporated herein.

In recent years, Western-style toilets have increasingly used a whirlpool (tornado method) for flushing water in order to improve the cleaning effect and save water. In this method, a flush water discharge port is provided in a concave portion inside the upper edge (rim) of the wall surface of the toilet bowl, and flush water after discharge is guided by the concave portion and flows down to the lower portion of the toilet bowl while forming a whirlpool. As a result, the flow rate of cleansing water has increased, which has reduced the amount of dirt on the toilet bowl. However, for example, toilets in facilities used by a large number of the public have been insufficiently cleaned. There is also a demand for a cleaning agent for household toilets to prevent toilet bowls from becoming dirty.
To address this problem, solid medications have been used that hang from the toilet bowl rim. Simply hanging them is effective for the lower part of the toilet bowl, but it is not effective for the concave part, so that it is necessary to manually clean the part that is troublesome to clean.
Hanging solid drugs are roughly classified into a type in which the solid drug is exposed and a type in which the solid drug is contained in a container. Of these, the type in which the solid drug is exposed (for example, Patent Document 1) may be consumed more than necessary depending on the type of drug, requiring frequent replacement. For this reason, Patent Document 1 states that it is preferable to provide the suspension member with a projecting portion that prevents contact between the solid medicine and the wall surface of the toilet bowl. On the other hand, a type in which a solid drug is contained in a container has a drug elution control effect (for example, Patent Document 2), but has a problem that it is difficult to prevent the container itself from being soiled. In addition, if the medicine or medicine container enters too much into the recess, there is also the problem that the wash water collides with it and is likely to scatter.

WO2007/148052 pamphlet JP 2009-68224 A

The present invention is a toilet cleaning solid chemical holder installed in a flush western-style toilet, which holds the chemical in a fixed position with at least a part of the chemical exposed, and moreover the chemical is supplied more than necessary. To provide a medicine which exerts an effect without being consumed, and exerts an effect even on the upper part of a toilet bowl, especially near the concave part inside the rim.

As a result of intensive studies aimed at solving the above problems, the present inventors have found that if the solid drug is used in a state where at least a portion of it is exposed, the problem of stains remaining on the device itself can be alleviated, and a method for fixing the drug has been devised. By doing so, the effect of cleaning the concave portion is also obtained, and even when the cleaning water is a whirlpool (tornado method), a pointed or streamlined water flow buffer is provided at one end that hits the upstream side of the water flow when viewed from the solid medicine.

FIG. 4 is a diagram showing a locking member of the medicine holder of the present invention; 1 is a cross-sectional view showing a cleaning set for a drug holder and a solid drug according to the present invention; FIG. FIG. 2 is a cross-sectional view of the cleaning set of the present invention when installed in the toilet, viewed from the center of the toilet. FIG. 2 is a cross-sectional view of the medicine fixing member (also referred to as medicine member) having a solid medicine of the present invention, as seen from above the toilet when installed.

In the present invention, the term "flush toilet" refers to a type of toilet that has a flushing water discharge port on a part or all of the rim of the toilet bowl, and the discharged flushing water cleans the entire inner wall of the toilet bowl. There is a type of toilet (Western style toilet) that you can sit directly on.
The "tornado type toilet" is one of the above-mentioned flush toilets in which flush water flows along the edge of the toilet bowl and gradually flows down the toilet bowl. Therefore, the tornado method does not include the one that naturally falls from the edge of the toilet bowl and flows below the toilet bowl.
"Rim" refers to the rim of the upper portion of the toilet bowl;
The term "recess" refers to a recess provided along the rim along the inside of the rim of the toilet bowl, along with the flush water discharge port, and is a portion that serves as a flow path for flush water, particularly in the Tornado method.
“Flush water” is water intended to flush excrement in a toilet such as a Western-style toilet, and refers to water that automatically or manually flows through the toilet bowl.
The term "medicine" refers to a water-soluble solid substance used in the present invention, and contains a medicinal ingredient for cleaning.
In the present invention, the term "drug holder" refers to the entire device for holding and using a drug in a toilet bowl, and may have separate constituent members so that it can be locked when in use. At least part of the members may be connected ready for use.
A “drug set” means a whole product including a drug and a drug holder, and like the above, the constituent members may be separate or partly connected. In particular, as will be described below, it is preferable that the drug is preliminarily fixed to the "medicine fixing portion" which is a constituent member of the drug holder.

The drug holder of the present invention is a member for installing a drug on the upper wall surface inside a flush toilet bowl such as a tornado type.
The drug holder is composed of at least both a locking member (A) and a drug fixing member (B) described below.

(A) Locking member The locking member comprises at least a locking portion for locking the drug holder of the present invention to the toilet rim,
a hanging part that extends from the locking part and hangs down from the solid medicine (C) toward the center of the toilet bowl when installed;
It includes a medicine supporting part extending from the lower part of the drooping part to support the medicine, and has elasticity.
Here, the terms "lower" and "lower" mean directions or positions when the medicine is installed in the toilet.
The locking member has elasticity as a whole and exerts an elastic recovery force.
Materials for the locking member include elastic plate-like materials such as plastics and metals, spring elements, and combinations of a plurality of materials including these materials. is preferred.

(locking part)
As for the structure of the locking portion, at least a clip-like curved or bent structure is required so that it can be hung on the rim of the toilet bowl. By doing so, the elastic recovery force is used to fix the rim portion at a fixed position, and the drug supporting portion and the drug fixing member (B) are pressed against the inner wall side of the toilet bowl through the hanging portion.

(hanging part)
The drooping part is linear and arranged substantially vertically when installed in the toilet. The length of the hanging part is not particularly limited, but if it is excessively long, the medicine will be placed near the center of the lower part of the toilet bowl and the effect of the present invention will not be obtained. More preferably, the length of the hanging portion is adjusted so that the medication enters the recess below the toilet bowl rim. Moreover, it is preferable to design the drooping portion so that the medicine is arranged in the recess even when the medicine is dissolved and the size is reduced.

(Drug support part)
The medicine supporting part extends in a substantially L shape at the lower part of the drooping part, and is a member that supports the medicine by being connected to the medicine fixing member (B) at least during use and fixing the medicine fixing member.
As for the "lower part of the drooping part", since the drooping part has the function of connecting the locking part and the medicine supporting part, it is not particularly necessary for the drooping part to protrude below the medicine supporting part. , the drug supporting portion is preferably extended to the “lower end of the drooping portion”.
The drug supporting portion may be connected in advance to the drug fixing member (B) by a method such as integral molding. That is, the locking member (A) and the drug fixing member (B) may be an integral member. However, as described below, it is preferable that the drug fixing member (B) and the drug (C) are formed integrally. It is preferable to use one member and lock both members when in use. The portion where both members are locked must have a fixed structure so that the elastic recovery force of the locking member (A) is transmitted to the drug (C) during use.
Means for locking the drug-fixing member (B) to the drug-supporting part include fitting, adhesion, and locking by fixing parts such as screws. preferably.
The drug supporting portion is preferably designed so that the drug is placed in the recess even when the drug is dissolved and becomes smaller.

At the time of use, the medicine supporting part is arranged substantially horizontally, substantially perpendicular to the substantially vertically arranged drooping part. When viewed from above the toilet bowl, the drooping portion is positioned toward the inside of the toilet bowl relative to the medicine, and the medicine supporting portion connects the drooping portion and the medicine fixing member. In addition, when looking at the toilet bowl longitudinal section passing through both members (A) and (B), the drug supporting portion is positioned inward of the toilet bowl relative to the drug fixing member and the drug, and supports the drug fixing member.
Since many conventional solid detergents for Western-style toilets require only hanging from the rim of the toilet bowl, the detergent or its container is suspended. That is, it is a mode in which a drug or a drug container is simply connected to the lower end of the drooping section referred to in the present invention.
In such a manner, the cleansing agent or its container is placed away from the inner periphery of the toilet bowl, and is less effective in cleaning the inner periphery of the toilet bowl, particularly the concave portion below the rim. In addition, the cleaning agent may float up due to the flow of cleaning water when cleaning the toilet bowl.
On the other hand, in the present invention, the cleaning agent can be placed in the inner periphery of the toilet bowl, particularly near the concave portion below the rim, and the cleaning effect for this vicinity is excellent. In the case of using a cleaning agent having a high foaming effect, it is expected that the foaming effect will be further enhanced by arranging the cleaning agent in the vicinity of the concave portion where the water flow is strong. In addition, it is possible to prevent the cleaning agent from being lifted up by the water flow. In particular, arranging the cleaning agent in the recessed portion below the rim portion, which is difficult for the user to see, is more aesthetically pleasing than the conventional method of using the cleaning agent.
In addition, in the present invention, the surface of the drug may be in contact with the inner wall of the toilet bowl. In particular, from the viewpoint of improving the cleaning effect on the concave portion, it is preferable that at least part of the surface of the medicine is in contact with the inner wall of the toilet bowl.

(B) Drug Fixing Member As described above, the drug fixing member (B) is locked to the drug support portion at least during use, and holds the solid drug (C) at least at the surface facing the inner wall of the toilet bowl exposed. It is a member that can be fixed in a closed state.
Here, "exposed" does not simply mean that water or air can flow (for example, when completely contained in a basket-like container), but at least a part of the surface of the drug can contact the inner wall of the toilet bowl. It means that you are exposed to a certain degree.
As a method for fixing the medicine by the medicine fixing member, specifically, part of the medicine may be protected by a container or a shield. It is preferable that it is fixed in a state in which the surface facing the inner wall is exposed.
A preferable structure of the drug-fixing member for exhibiting such an effect is a structure that functions as a "bone" that fixes the drug inside the drug. However, at least the portion of the medicine fixing member that engages with the medicine supporting portion needs to protrude outside the medicine. Further, as exemplified in the section "Manufacturing Method of Drug Member" below, when connecting a plurality of drugs, the drug fixing member may protrude outside the drugs between the drugs. Although the specific form of this "bone structure" is not particularly limited, it may be rod-shaped or plate-shaped. Morphology is preferred. In addition, it is preferable that the solid medicine is present in the center so that part of the medicine remains solid and is not detached by the water flow until the end of use.
Materials for the drug-fixing member include plastics, metals, and the like, preferably plastics.
The position of the locking portion of the drug fixing member with respect to the drug supporting portion is not particularly limited. Regarding the position of the locking portion at the time of installation, any of the upper side, the vicinity of the center, and the lower side of the medicine fixing member can be selected according to the ease of manufacture. Also, regarding the horizontal direction when the drug is viewed from the center of the toilet at the time of installation, the engaging portion is positioned near the center of gravity of the portion where the drug fixing member and the drug are combined (drug member (D) described later). If designed, it is preferable in that it is easy to install stably.

(water flow buffer)
When the chemical is placed in the recessed portion below the rim, especially in a tornado-type toilet, the water flow here is strong, so as described in the background art section, the flushing water collides with this and is easily splashed. There are drawbacks. In order to prevent this, it is effective to provide a pointed or streamlined water flow buffer at least at the end of the drug fixing member that is on the upstream side of the water flow when viewed from the drug.
It is preferable that the water flow buffer has a diameter similar to that of the medicine. The term "diameter" used herein refers to the length occupied by the medicine or the water flow buffer on the vertical cross-sectional view of the toilet. The diameter of the water flow buffering portion need not be particularly large compared to the diameter of the drug, and it is preferable that the ratio of the diameter of the water flow buffering portion/the diameter of the drug is 1/2 or more.
Such a water flow buffer not only prevents splashing of water, but also has the effect of preventing excessive dissolution of the drug.
In particular, it is preferable to design the shape of the water flow buffer so that the water flow detours toward the inside of the toilet rather than toward the wall side of the water flow buffer. As a result, splashing of water is prevented, and the effect of reducing the dissolution of the drug is enhanced.
The water flow buffer is provided integrally or separately, preferably integrally, with the end portion of the drug fixing member. Moreover, the water flow buffer may be provided not only at one end on the upstream side of the water flow when viewed from the medicine, but also at both ends.
When the water flow buffer is separately provided at the end of the drug fixing member, it may be fixedly provided by means of fixing parts such as adhesion or screws, or may be provided detachably by means of fitting or the like. good too.
Materials for the water flow buffer include plastics, metals, and the like, preferably plastics.

(C) Solid drug The drug in the present invention is not particularly limited as long as it is a water-soluble solid substance and contains a medicinal ingredient for cleaning.
Although the form of the medicine is not particularly limited, it is preferable to have a diameter that allows it to enter the recess under the rim portion.
In addition, the usable period of the medicine can be set arbitrarily depending on the composition of the medicine, the manufacturing method, the form, etc., but it is preferable to secure a volume that does not need to be replaced in a too short period of time. In order to achieve both of the above, it is preferable to have a form having a certain length so that it can enter along the concave portion below the rim portion.
The form of the drug is not particularly limited, and includes spherical, ellipsoidal, cylindrical, rectangular parallelepiped, etc., and forms with through holes and unevenness. An optimum one can be selected according to the design effect and the like.

A component contained in the drug should have at least a cleaning effect. In particular, it is preferable if it has an appropriate foaming effect to the extent that it does not interfere with the use of the toilet bowl, because it exhibits a deodorizing effect and an effect of preventing splashing during excretion.
Components for exhibiting the above effects include nonionic surfactants and/or ionic surfactants. For production by melt molding, it is preferred to contain a nonionic surfactant as a main component. Furthermore, a solid acid, deodorant or antibacterial component, perfume, coloring component, etc. may be added.
Furthermore, if it is necessary to obtain effects such as maintaining the strength of the drug, changes in solubility according to the size of the drug during use, and changes in fragrance and coloring components, depending on the part of the drug (for example, near the surface and near the center) and) may have different component compositions.

(Nonionic surfactant)
Examples of nonionic surfactants include propylene oxide/ethylene oxide copolymers, polyoxyethylene nonylphenol ethers, alkyltrimethylammonium bromide, and polyethylene glycol.

(ionic surfactant)
As the ionic surfactant, an anionic surfactant is preferred. Specifically, sulfates such as polyoxyethylene lauryl sulfate, carboxylates such as myristate, and the like can be exemplified.

(solid acid)
The solid acid has the effect of preventing scale called urinary calculus to which calcium-based compounds and the like formed by decomposition of urine adhere. In addition, it has an effect of suppressing microorganisms, and is expected to have a deodorizing effect.
A solid acid is an acidic substance that is solid at room temperature and does not react with calcium ions to form a salt with a solubility of 0.001 g/100 g (water) or less in water in the pH range of 5 to 8.5. , in particular, is not limited. Examples thereof include water-soluble acidic salts such as sodium hydrogensulfate, potassium hydrogensulfate and ammonium hydrogensulfate, water-soluble salts of strong acids and weak bases such as ammonium chloride and ammonium sulfate, boric acid and sulfamic acid. Organic acids solid at room temperature such as succinic acid, citric acid, maleic acid, isophthalic acid, tartaric acid, fumaric acid, adipic acid, salicylic acid, benzoic acid and malic acid can also be used. It can be used as a mixture of species or more.

(Deodorant or antibacterial ingredient)
The deodorant component is not particularly limited as long as it is a deodorant component that can diffuse into water. The water-diffusible deodorant component includes a water-soluble deodorant component, a water-dispersible deodorant component, and the like.
Examples of water-soluble deodorant components include quaternary ammonium salts, catechins, tannins, amino acids, and the like. Quaternary ammonium salts are particularly preferred because they also have an antibacterial effect.
Examples of deodorant components that can be dispersed in water include charcoal and activated carbon.

(perfume)
The fragrance is not particularly limited as long as it has a pleasant fragrance, but plant-based fragrances represented by eucalyptus essential oil are preferred.

(Coloring component)
Although the coloring component is not particularly limited, one that is water-soluble is preferred. Moreover, the coloring component itself may have effects such as a deodorizing effect, a fragrance, and a cleaning effect.

(D) Drug Member In the present invention, when the solid drug (C) fixed to the drug fixing member (B) is an independent member, this member is referred to as a drug member (D).
In the present invention, it is necessary that the drug fixing member and the drug are fixed at least during use. If the cleaning agent is of the type housed in a container, it is easy to refill only the agent after the agent is consumed. It is difficult to achieve compatibility with a refillable type. Therefore, it is preferable that the drug fixing member and the drug are pre-fixed "medicine members".
Specifically, the drug member includes, as described above, a drug fixing member in which the drug is fixed by the bone structure inside the drug.
The drug member (D) can be used together with the locking member (A) as a drug set for a tornado type or other flush toilet bowl. The locking member (A) and the drug member (D) may be supplied as a set in an attached state, or may be supplied as separate members as a set, and both may be attached at the time of use. .

(Manufacturing method of drug member)
The method of manufacturing the drug member as described above is not particularly limited as long as there is no concern that the drug will detach from the drug fixing member before the end of use. Among them, melt molding is preferable in that it is easy to manufacture.
Melt molding is particularly advantageous when the medicament is to be in the form of some length that can enter along the recess under the rim, as described above. In this case, it is possible to mold the entire drug portion as a single body, but it is easier to mold the drug portion by dividing it into a plurality of parts in the longitudinal direction.
An example of the manufacturing method is given below. A plurality of rectangular parallelepiped containers for containing the melted drug are arranged in series. The drug-fixing member is fitted in the row of containers, and has a curved shape that protrudes outside the container between the containers. By injecting a melted drug into these containers and solidifying it by cooling, a drug member in which a plurality of rectangular parallelepiped drugs are connected by a drug fixing member is obtained.

One aspect of the drug holder and cleaning set of the present invention will be described below with reference to the accompanying drawings, but the technical scope of the present invention is not limited to the accompanying drawings.
