However, many of the liquid soaps are likely to form a solidified product or the like when a small amount remains in, for example, a narrow passage such as a valve portion or an orifice portion and a complicated passage portion. In particular, when used at intervals in time, it often causes inconveniences such as impeding the passage of the following liquid and hindering the normal operation of the valve.

Further, depending on the type of liquid soap, the soap component in the liquid and the component having the property of corroding metal etc. may be blended in the additive component. In the case of such a soap liquid, In many cases, the metal portion of the dispenser during use is rusted or corroded at a portion in contact with the soap solution, thereby impairing the normal function of the dispenser.
In particular, when a metal is used for the above-mentioned valve constituent member, both phenomena of solidification and corrosion overlap in the valve portion, hinder the normal operation of the valve, and in extreme cases, blockage of liquid flow occurs.

Further, some of the liquid soaps contain solid fine particle components such as abrasive powder in the liquid,
This type of liquid soap has a slight viscosity and is inferior in fluidity of the liquid, so that the valve portion and the like are apt to be clogged. Furthermore,
Due to the abrasion effect of the abrasive powder dispersed in the liquid, when the valve portion member, particularly when it is made of metal or the like, the metal portion, for example, a metal liquid discharge adjusting ball is worn, Blockages and hinders the proper function of adjusting the liquid volume.

Therefore, the object of the present invention is to avoid the above-mentioned inconveniences and to apply it to various soap liquids, especially liquid soaps containing various additives, abrasives, etc.

Since the liquid soap package consisting of the valve mechanism part is composed of non-metal members, especially plastic, rubber, etc., even when the liquid soap contains metal corrosive or abradable components such as additives and abrasives. Another object of the present invention is to provide a liquid soap dispenser which has excellent corrosion resistance and abrasion resistance and can achieve a stable liquid dispensing function.

Still another object of the present invention is that the liquid soap package portion of the dispensing device is constructed so that it can be easily replaced.
And since it is low cost, it is possible to replace and use only the liquid soap package portion for each type of liquid soap by so-called discarding, or for each lot.
It is an object of the present invention to provide a soap liquid dispenser which can be dispensed and used in a pure state at all times without causing contamination or alteration of liquid soaps of each lot.

[0010]

The liquid soap dispenser of the present invention comprises a pouch containing liquid soap, a liquid soap metering and discharging elastic pipe attached to the pouch, and a valve mechanism provided at the tip thereof. (A), a holding part for holding the pouch storage part and the valve mechanism, and a pressing member provided between the pouch storage part and the valve mechanism holding part for squeezing and pressing the elastic pipe to discharge a predetermined amount of liquid soap. With housing (B)
The valve mechanism provided at the tip of the elastic pipe is (i) formed of an elastic body such as various natural or synthetic rubbers, has a flange at one end, and has a passage in the axial direction. And has the other end of the passage closed in a normal state (a state in which no pressure is applied to the passage), and when the pressure is applied to the passage, the other end of the passage is released and opens. (Ii) A liquid soap outlet is provided at the bottom, an inner cylinder is provided at the top, and an accommodation portion for accommodating the above-mentioned check valve is provided inside the inside thereof, and a flange is provided at the middle of the outside. A lower part formed, and (iii) an upper part in which a shoulder part is formed in the upper part, a flange is formed in the lower part of the outer cylinder, and an inner cylinder housing part for housing the inner cylinder part of the lower part in (ii) is formed. And engaging the upper part (iii) and the lower part (ii) with their flanges. , The gap between the upper edge of the inner cylinder of the lower part and the shoulder of the upper part is made slightly smaller than the flange thickness of the check valve, and the check of the upper inner cylinder of the lower part (ii) is performed. A check valve is inserted into the valve accommodating portion so that the lower surface side of the flange is in contact with the upper edge of the inner cylindrical portion, and the lower part (ii) and the upper part (iii) in which the check valve is inserted are inserted into those flanges. It is a remarkable feature that the check valve flange is configured to be pressed and sandwiched between the shoulder portion of the upper part and the upper edge of the lower part when engaged with each other.

Check valve (i) used in the valve mechanism of the present invention
Is made of an elastic material such as natural rubber, nitrile rubber, or other synthetic rubber, and is specifically formed into a shape as shown in FIG. As is clear from FIG. 3 (a), at the lower end of the check valve, the passage through which the liquid passes is closed, and in a normal state, the soap liquid remains in the internal passage. Exists. In the distributor of the present invention, when the elastic pipe provided in the upstream portion of the valve mechanism is pressed in an ironing shape by, for example, a roller mechanism, a distribution arm mechanism or the like and a pressing force is applied, the pressure causes the valve to move. The normally closed passage at the lower end is opened,
The liquid flows out from here, and the amount of soap liquid corresponding to the pressing operation of the elastic pipe is discharged from the discharge port of the lower part (ii). When the pressing of the elastic pipe in the upstream portion is released, the tip portion of the valve is closed again. As is apparent from the structure of the valve shown in FIG. 3, the tip of the valve which is once closed does not open due to the reverse pressure of the liquid from the discharge side, and the reverse flow of the discharged liquid is blocked, and the valve functions as a check valve.

A conventional valve mechanism used for adjusting and distributing a relatively small amount of liquid in such a liquid distributing device is, for example, a check valve composed of a metal ball and a spring as shown in FIG. Although a valve mechanism is generally used, in a check valve having such a structure, in order to achieve proper flow rate adjustment and complete prevention of fluid backflow,
It is required that the surface shape of the ball is smooth and that the elastic stress of the spring has an appropriate value.

Therefore, if solid residues of liquid soap or the like adhere to the balls or springs, or if the liquid contains abrasive powder or the like, they become solid and stick to each other. The normal operation of the check valve mechanism is hindered.

Furthermore, when the liquid contains a metal corrosive component or contains abrasive powder, etc., the ball surface or spring may be rusted, or the ball may be corroded or abraded. Deformation, surface roughness, or spring stress change, and normal operation of the valve mechanism is not achieved.

On the other hand, the valve mechanism of the present invention has the above-mentioned relatively simple structure, and the liquid flow path thereof is simpler than that of the conventional check valve using a metal ball, a spring, etc. Also in use, there is an advantage that the blockage of the flow path due to the production of solid matter and the malfunction of the valve function can be avoided.

Further, the above (i), (i
Since the members i) and (iii) are formed of non-metallic members such as plastic and rubber and have the shape as shown in FIG. 3 as described above, the corrosion resistance is good. In addition, the inconvenience of the conventional valve due to the above-mentioned wear is avoided. There is also an advantage that the cost is low.

The pouch for filling the soap liquid of the liquid soap dispenser of the present invention usually comprises a bag-shaped container formed of a plastic film. An opening is provided in the pouch,
An elastic pipe is connected to the opening, and the valve mechanism described above is provided at the tip thereof.

The pipe and the valve-equipped pouch filled with the soap solution are set in the pouch accommodating portion of the housing with the pipe and the valve facing downward, and the elastic pipe ironing and pushing means (equal to the lower part of the accommodating portion) ( (For example, a roller pressing means known per se, a pressing means composed of a backup block and a distribution arm, etc.) is mounted with the elastic pipe portion, and the valve mechanism is set and fixed on the valve mechanism supporting portion of the housing provided under the elastic pipe portion. To support the valve mechanism.

In the liquid dispensing operation of the liquid soap dispenser, the pipe pushing means is actuated by automatic or manual operation to push the pipe in an ironing manner to discharge the soap liquid in the pipe in a fixed amount. At this time, the valve mechanism operates and acts as described above.

The opening to which this pipe is connected is operated so as to secure the joint with the elastic pipe with sufficient strength, and when the pouch filled with the liquid is housed in the housing part, the pipe is squeezed and pressed. In order to ensure the elastic recovery of a sufficient shape at the time of release, it is preferable to mount a liquid guide member, for example, as shown at 4 in FIG. 3 by means such as adhesion.

The pouch used in the present invention may be a so-called discarded pouch type for each pouch, or may be a type in which only the liquid is newly filled after use and repeatedly used.

In the former case, there may be one opening, and in this case, the liquid filling port and the pipe connecting port can be shared.
In the latter case, both openings are usually provided separately.

The material of the plastic film used in the pouch of the present invention is not particularly limited as long as it is a plastic having sufficient strength to contain and hold a predetermined amount of liquid soap, and for example, polyethylene, Polyolefins such as polypropylene, polybutene, poly-4-methyl-1-pentene or copolymers of these olefins, polyvinyl chloride, polyvinylidene chloride, vinyl or vinylidene copolymers such as polyvinyl alcohol, fluorine-based resins, In addition to polycarbonate, polyacetal, cellulose acetate, saturated polyester, polyamide and the like, resins such as polyimide, polyphenylene oxide, polysulfone, TPX polymer and polyparaxylene can be exemplified.

A so-called laminated film obtained by laminating the above-mentioned various resin films can also be preferably used, and a laminate of a nylon resin film and a linear low-density polyethylene (LLDPE) film is particularly preferable.

The thickness of the film used for the pouch depends on the volume of the soap solution filled in the pouch, the specific gravity of the solution, and other physical properties.
Although it is appropriately set in consideration of the strength of the film material resin, normally, when the filling volume is about 300 to 600 ml,
The film thickness is preferably set to about 50 μm to 200 μm. In the case of the above-mentioned laminate, the nylon film is 10 to 50 μm and the L-LDPE is 30 to 1
It is desirable to have a thickness of 50 μm.

When the liquid soap package of the invention is installed in the housing, a predetermined amount of the soap solution in the pouch is discharged by the action of the pipe squeezing and pressing means installed between the pouch storage portion of the housing and the valve mechanism holding portion. In the liquid soap dispenser of the present invention, the amount of discharged liquid discharged by one operation is determined by the mutual relationship between the internal capacity of the elastic pipe and the operation of the pressing means and the valve mechanism depending on its use and purpose of use. It is set to an appropriate amount.
