DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container holder for holding a container containing electrolyzed water for producing electrolyzed water for, for example, disinfection and sterilization (sterilization), and an electrolyzed water supply for supplying the electrolyzed water. Related to the device.

[0002]

2. Description of the Related Art For example, in the fields of agriculture and food,
Electrolyzed water generated by electrolysis is useful,
Generally known.

[0003] Electrolyzed water has excellent disinfecting and disinfecting effects and is highly safe. Therefore, in addition to its use in kitchens of ordinary households, it is also used for disinfecting and disinfecting the human body, especially for washing and cleaning fingers.
Use in the field of disinfection and medical care, for example, sterilization and disinfection of skin, wounds, diseased parts, incisions, percutaneous openings of indwelling catheters, stomas (ostomy), anus, etc., is being studied. .

[0004] In order to increase the electric conductivity of the water to be electrolyzed, a solute which generates ions by dissolution, for example, sodium chloride, potassium chloride, magnesium chloride, calcium carbonate, or the like is added to such electrolyzed water, and if necessary, the pH is adjusted. Water (electrolyzed water) to which an acid for the addition is added is obtained by electrolysis.

As an apparatus for supplying such electrolyzed water, there is an electrolyzed water supply apparatus described in Japanese Patent Application Laid-Open No. 9-248573. In the electrolyzed water supply device, the electrolyzed water is stored in a container, the electrolyzed water is suctioned from the container by a pump, transferred to an electrolysis unit, and electrolyzed water is generated. It is configured to inject.

[0006] In such an electrolyzed water supply device, it is preferable that the sterilization and disinfecting ability of the electrolyzed water injected from the nozzle is constant, so that the pH of the generated electrolyzed water and the effective chlorine concentration are stable. Is required.

However, there is a problem that the pH of the electrolyzed water and the effective chlorine concentration change with time due to the following reasons, and the stability is lost.

When the container for storing the electrolyzed water is made of a soft material, the pump is operated to draw the electrolyzed water from the inside of the container, and as the amount of the stored liquid decreases, the thickness of the container itself also increases. Deformation decreases, but if for some reason a resisting force acts on the container to prevent the deformation of the container, negative pressure is generated in the container and in the flow path between the container and the pump. The flow rate of water (the flow rate through the electrolytic section) decreases. When the electrolysis conditions (applied voltage) in the electrolysis unit are constant, such fluctuations in the flow rate of the water to be electrolyzed are caused by fluctuations in the pH and effective chlorine concentration of the electrolysis water generated in the electrolysis unit and injected from the nozzle. Bring.

[0009] The above-mentioned problems may occur in a container for storing a liquid other than the water to be electrolyzed.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a container holder and an electrolyzed water supply device of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

FIGS. 1, 2 and 3 are front views each showing an example of a container held by the container holder of the present invention.
FIGS. 4 and 5 are a side view and an exploded perspective view, and FIGS. 4 and 5 are overall side views showing an embodiment of an electrolyzed water supply apparatus provided with the container holder of the present invention. In the following description,
1, 2, 4, and 5, the upper side is "upper" or "upper end", and the lower side is "lower" or "lower end".

First, the container 10 will be described with reference to FIGS. The container 10 is formed in a bag shape by sealing both ends of a flexible tubular sheet 11.

The tubular sheet 11 is manufactured by, for example, inflation molding, and has folded portions 12 that are folded on both sides thereof so as to project toward the inside of the container 10. The folded portion 12 is deformed in accordance with a change in the amount of liquid in the container 10 to keep the pressure in the container 10 constant.

At the lower end of the container 10, a band-shaped seal portion 13 is formed. A port (port) that functions as a discharge port for the liquid in the container 10 is provided at the upper end of the container 10.
14 is mounted. A tube 15 inserted into the container 10 is formed integrally with the mouth portion 14. Further, two flanges 16 are formed on the outer periphery of the mouth portion 14.

A predetermined amount of liquid is stored in the container 10. In the present embodiment, water to be electrolyzed that is subjected to electrolysis and becomes electrolyzed water is stored.

The electrolyzed water is, for example, water containing salts such as sodium chloride, potassium chloride, calcium chloride, and magnesium chloride. In addition, hydrochloric acid, acetic acid,
It is preferable to contain an acid such as ascorbic acid, succinic acid, citric acid and the like.

The water to be electrolyzed may contain various additives, for example, a buffer for pH adjustment, a phosphate, a carbonate and the like, if necessary. In the following description, a description will be given using a sodium chloride aqueous solution as the water to be electrolyzed.

Examples of the constituent material of the tubular sheet 11 in the container 10 include polyvinyl chloride, polyethylene, polypropylene, polyolefin such as ethylene-vinyl acetate copolymer and ethylene-vinyl alcohol copolymer, polyethylene terephthalate, polybutylene terephthalate and the like. Various resin materials such as polyester, polyurethane, polyamide, polyimide, and polystyrene; various rubber materials such as natural rubber, isoprene rubber, butyl rubber, styrene butadiene rubber, acrylic rubber, and fluorine-based rubber; polyester elastomers; polyamide elastomers;
Various thermoplastic elastomers such as a butadiene-styrene copolymer can be used, and one or a combination of two or more of them can be used (polymer alloy, polymer blend, laminate, etc.). In order to further reduce the gas permeability of the tubular sheet 11, a gas barrier layer formed of a metal layer such as an aluminum layer may be used.

By using the cylindrical sheet 11 that is bonded to a laminate of a plurality of layers or a gas barrier layer, the gas permeability of the cylindrical sheet 11 can be further reduced by changing the stored electrolyzed water over time. In order to prevent physical deterioration and deterioration,
preferable.

The material of the mouth 14 and the tube 15 may be polyolefin such as hard polyvinyl chloride, polyethylene, or polypropylene; polyester such as polyethylene terephthalate or polybutylene terephthalate;
Various resin materials (especially hard resins) such as polycarbonate, polymethyl methacrylate, polyacetal, and ABS resin are exemplified.

When the container 10 is in an upright posture (a posture in which the longitudinal direction of the container 10 is substantially vertical), the longitudinal direction of the container 10 depends on the amount of the electrolyzed water in the container. (Up and down direction). That is, when the liquid volume of the electrolyzed water inside the container is almost full (at the time of full liquid), the container 1
Since the tubular sheet 11 constituting the container 0 is pulled to the side, the bent portion 12 is opened, and the thickness of the container 10 (width in the horizontal direction in FIG. 2) is increased. The length (the length in the vertical direction) is the shortest (hereinafter, this state is referred to as a “contracted state”). Then, as the amount of the electrolyzed water in the container decreases, the bent portion 12 is folded and the thickness of the container 10 decreases, so that the length of the container 10 gradually increases. When almost all of the electrolyzed water inside the container is discharged (at the time of empty liquid), the bent portions 12 are in an overlapped state, the thickness of the container 10 is the thinnest, and the length of the container 10 is the longest (hereinafter, referred to as the following). This state is called an “extended state”).

The capacity of the container 10 is not particularly limited, but is preferably about 100 to 1000 ml, more preferably about 200 to 500 ml in consideration of the miniaturization of the apparatus.

As shown in FIGS. 4 and 5, the electrolyzed water supply device (electrolyzed water injection device) 1 of the present invention has a container holder 2 for holding a container 10. The container holder 2 includes a base 21
And an arm 22 erected on one end of the base 21. The container holder 2 is placed on the horizontal floor, for example, by the base 21. The arm 22 is bent toward the other end of the base 21 on the way, and the upper end 2 of the arm 22 is bent.
Reference numeral 3 extends above the base 21 almost in parallel with the base 21.

Below the upper end 23 of the arm 22, a container 1
A support member (support portion) 3 for supporting and fixing the upper end portion of the “0”, that is, the mouth portion 14 is provided. The support member 3 has a notch (recess) at the center, and the notch 14
The portion between the two flanges 16 is fitted to support the mouth portion 14 detachably. In a state where the mouth 14 is supported by the support member 3, the upper flange 16 is engaged with the upper surface of the support member 3 to prevent the container 10 from dropping. Also,
When the mouth 14 is supported by the support member 3, the mouth 14
The upper end opening of the pump 5 is installed inside the upper end 23.
Fluid-tight connection to the flow path to

A pump 5 is installed inside the container holder 2 as a liquid sending means for sucking and sending the electrolyzed water from inside the container 10 supported by the support member 3. An electrolyzing means (electrolysis unit) 6 for electrolyzing (electrolyzing) the water to be electrolyzed sucked at 5 to generate electrolyzed water is provided. In the present embodiment, the pump 5 and the electrolytic means 6
It is installed inside the upper end 23.

The electrolytic means 6 comprises an electrolytic cell 61 and the electrolytic cell 6
1 and a plate-like anode 62 and a cathode 6
3 is comprised. The electrolytic cell 61 is preferably a non-diaphragm electrolytic cell having no diaphragm between the anode 62 and the cathode 63. Thereby, as compared with the case of using an electrolytic cell having a diaphragm, the configuration of the apparatus can be further simplified, and since no alkaline waste liquid is generated, a required amount of electrolyzed water is generated with a smaller amount of electrolyzed water. There is an advantage that can be. In the present invention, it goes without saying that an electrolytic cell having a diaphragm may be used.

The left end surface of the upper end 23 in FIG.
A nozzle 7 for ejecting the electrolytic water generated by the electrolytic means 6 is provided. The form (spraying form) of the nozzle 7 and the like are not particularly limited. For example, one that can eject one or several lines of electrolyzed water (as a jet), one that ejects electrolyzed water in a shower shape, Examples include those that spray in the form of a mist, and those that eject a jet stream so as to swing or rotate. Further, it may be possible to switch (selectable) to two or more injection modes among such injection modes, or to use these multiple injection modes in combination.

The nozzle 7 may be detachable with respect to the upper end 23, and in particular, may be configured such that a plurality of nozzles 7 of different types and shapes are interchangeably mounted.

The nozzle 7 and the electrolytic cell 61, and the electrolytic cell 61 and the pump 5, are connected by pipes.

In the middle of the arm 22, a trigger (lever) 24 is provided as an operation member for performing an operation for generating electrolyzed water and ejecting the same from the nozzle 7. By operating the trigger 24 with a finger or the like, a switch (trigger switch) 25 can be turned on / off.

The power supply unit 8 and a current control circuit (a constant current circuit or a constant voltage circuit) 9 for controlling the current applied to the electrode pair of the electrolytic means 6 are provided inside the arm 22 of the container holder 2.
And is installed. The power supply unit 8 is loaded with, for example, a battery. Alternatively, an AC power supply or an automobile battery may be used.

The pump 5 is connected to the power supply unit 8 via a switch 25. The anode 62 and the cathode 63 of the electrolysis means 6 are connected to the power supply unit 8 via the current control circuit 9 and the switch 25.

When the trigger 24 is pressed with a finger and the switch 25 is
Is turned on, power is supplied from the power supply unit 8 to the pump 5, and the pump 5 is operated to suck the electrolyzed water in the container 5. The electrolyzed water discharged by the suction is sent to the electrolytic cell 61 via the pump 5.

When the switch 25 is turned on, a current flows between the anode 62 and the cathode 63. At this time, by the operation of the current control circuit 9, the applied current (applied voltage) between the anode 62 and the cathode 63 is controlled to be constant.

When electricity is supplied between the anode 62 and the cathode 63 of the electrolysis means 6 and the water to be electrolyzed sent by the operation of the pump 5 passes through the electrolysis tank 61 in this state, the electrolyzed water is electrolyzed. By the reaction represented by the following formula, hypochlorous acid (HOCl) is generated on the anode 62 side, and sodium hydroxide (NaOH) and hydrogen gas (H ₂ ) are generated on the cathode 63 side, and the electrolytic water containing these is generated. Is obtained. Then, the electrolyzed water is injected from the nozzle 7. The jet of the jetted electrolytic water collides with an object to be disinfected and disinfected (for example, the surface of a living body), and disinfects and disinfects.

When the finger is released from the trigger 24, the electrolytic means 6
The power supply to the electrode pair and the power supply to the pump 5 are stopped, and the supply of the water to be electrolyzed, the generation and the injection of the electrolyzed water stop almost simultaneously.

The electrolytic water injected from the nozzle 7 has its p
H is preferably from 3 to 7, more preferably from 4 to 6.5, even more preferably from 4.5 to 5.5. If the pH is too low, the abundance ratio of chlorine molecules in the electrolytic water tends to increase, and the effective chlorine amount becomes unstable,
Conversely, if the pH is too high, the abundance ratio of hypochlorite ions in the electrolytic water tends to increase, and in any case, the disinfecting and disinfecting effects are reduced. Therefore, the pH of the electrolyzed water
Is preferably in the above range.

The effective chlorine concentration of the electrolyzed water injected from the nozzle 7 is preferably about 1 to 200 ppm, and more preferably about 30 to 100 ppm.
If the effective chlorine concentration is too low, the disinfecting and disinfecting effects may not be sufficiently exhibited when the striking force due to the jet is relatively low, and if the effective chlorine concentration is too high, it may be used on the human body. , Safety is reduced. Therefore, if the application is not for the human body, the effective chlorine concentration is 200p
pm.

In the electrolyzed water supply apparatus 1 as described above, the pump 5 is energized to start the liquid supply, and at the same time, the energization is performed between the anode 62 and the cathode 63 to electrolyze the electrolyzed water. Then, the generated electrolyzed water is injected. That is, by the operation of the trigger 24, the generation of the electrolyzed water by the operation of the electrolysis means 6 and the ejection of the electrolyzed water from the nozzle 7 by the liquid supply are performed synchronously. As a result, the required amount of electrolyzed water can be generated and used when needed, and waste can be eliminated.Also, electrolyzed water with high activity can always be supplied, and excellent disinfection and sterilization effects can be obtained. Obtained stably.

As described above, the container 10 extends vertically in accordance with the amount of liquid in the container. As shown in FIGS. 4 and 5, the base 21 of the container holder 2
A positioning portion 4 is provided for restricting the position of the lower end portion (seal portion 13) of the container 10 while allowing the container 10 to extend. The positioning section 4 is provided at a position directly below the support member 3.

The positioning section 4 in this embodiment is similar to the positioning section shown in FIG.
A cross section extending in a direction perpendicular to the inner paper surface is formed by a V-shaped (or U-shaped) groove 41.

As shown in FIG. 4, when the container 10 is in the contracted state, the lower end of the container 10, that is, the sealing portion 13
Are housed in the groove 41. Thereby, the container 10
4 is restricted to some extent in the lateral direction in FIG. At this time, the lower end of the seal portion 13 is separated from the bottom (lowest portion) 42 of the groove 41 by a predetermined distance. Assuming that the separation distance is T and the difference between the length of the container 10 in the contracted state and the extended state (the maximum movement distance of the lower end of the container 10) is S, it is preferable that S ≦ T, and 1.1S ≦ T ≦ 4.0
S is more preferred.

As a specific value of T, for example, 1
It can be about 1 to 40 mm.

When the amount of liquid in the container 10 decreases due to the generation and injection of the electrolyzed water, and the container 10 in the contracted state gradually elongates,
The seal portion 13 also descends accordingly, but in this case,
The seal portion 13 is provided in a space near the bottom (lowest portion) 42 of the groove 41.
Can escape.

As shown in FIG. 5, when the container 10 is in the extended state, that is, when the seal portion 13 is lowered most, the seal portion 13 is housed in the groove 41. At this time, the lower end of the seal portion 13 is not in contact with the bottom (lowest portion) 42 of the groove 41 or is in slight contact with it.

By providing such a groove 41, the lower end of the seal portion 13 abuts when the container 10 is extended while restricting the position of the lower end of the container 10 to prevent the container 10 from being extended. Prevent or suppress the generation of resistance. If the elongation of the container 10 is hindered, the thickness of the container 10 is prevented from decreasing, and therefore, the inside of the container 10 becomes negative pressure, and the amount of the electrolyzed water supplied by the pump 5 (the flow rate through the electrolytic cell 61).
, And as a result, the pH of the electrolyzed water injected from the nozzle 7 and the effective chlorine concentration change. However, in the present invention, since the elongation of the container 10 is not hindered, such a disadvantage does not occur, and the pH of the electrolyzed water injected from the nozzle 7 is not changed.
And the fluctuation of the effective chlorine concentration can be suppressed, and the sterilizing and disinfecting ability of the electrolyzed water can be stabilized.

FIGS. 6 and 7 are overall side views showing another embodiment of the electrolyzed water supply device provided with the container holder of the present invention. Hereinafter, the embodiment shown in these figures will be described, but the description of the same items as in the above-described embodiment will be omitted.

The electrolytic water supply device 1 shown in FIGS. 6 and 7
Is the same as the above-described embodiment except that the configuration of the positioning portion 4 of the container holder 2 is different.

That is, the positioning section 4 in the present embodiment is constituted by an inclined surface 43 inclined at a predetermined angle with respect to the lower surface (horizontal plane) of the base 21. The inclination angle θ of the inclined surface 43 is not particularly limited, but is preferably about 10 to 80 °, and more preferably about 15 to 60 °.

As shown in FIG. 6, when the container 10 is in the contracted state, the lower end of the container 10,
Is in slight contact with the vicinity of the top of the inclined surface 43. Thereby, the movement of the lower end of the container 10 in the lateral direction in FIG. 6 is restricted to some extent. At this time, since the container receives the reaction force from the inclined surface 43, the container 10 may be slightly inclined with respect to the vertical direction.

When the amount of liquid in the container 10 decreases due to the generation and injection of the electrolyzed water, and the container 10 in the contracted state gradually elongates,
Along with this, the seal portion 13 slides downward along the inclined surface 43. That is, the seal portion 13 can be released below the inclined surface 43.

As shown in FIG. 7, when the container 10 is in the extended state, the lower end of the container 10 is curved.

By providing such an inclined surface 43, the lower end of the seal portion 13 abuts when the container 10 is extended while restricting the position of the lower end of the container 10 to prevent the container 10 from being extended. Prevent or suppress the generation of excessive resistance. As a result, as described above, the inside of the container 10 becomes negative pressure, and it is possible to prevent the amount of water to be electrolyzed by the pump 5 (the flow rate through the electrolytic cell 61) from being reduced.
Fluctuations in the pH and effective chlorine concentration of the electrolyzed water to be injected can be suppressed, and the sterilizing and disinfecting ability of the electrolyzed water can be stabilized.

FIGS. 8 and 9 are overall side views showing another embodiment of the electrolyzed water supply device provided with the container holder of the present invention. Hereinafter, the embodiment shown in these figures will be described, but the description of the same items as in the above-described embodiment will be omitted.

The electrolytic water supply device 1 shown in FIGS. 8 and 9
Is the same as the above-described embodiment except that the configuration of the positioning portion 4 of the container holder 2 is different.

That is, the positioning portion 4 in the present embodiment is provided with the same inclined surface 43 as described above inclined at a predetermined angle (the angle θ) with respect to the lower surface (horizontal plane) of the base 21, and is installed above the inclined surface 43. And an auxiliary plate (auxiliary member) 44.

The auxiliary plate 44 is, for example, 5 to 4 with respect to the inclined surface.
It is fixedly installed with an angle (opening angle) of about 5 °. In addition, the auxiliary plate 44 may be rotatably installed.

As shown in FIG. 8, when the container 10 is in the contracted state, the lower end of the container 10,
Is in slight contact with the vicinity of the top of the inclined surface 43. Thereby, the movement of the lower end of the container 10 in the lateral direction in FIG. 8 is restricted to some extent. At this time, since the container receives the reaction force from the inclined surface 43, the container 10 may be slightly inclined with respect to the vertical direction.

When the amount of liquid in the container 10 decreases due to the generation and injection of the electrolyzed water, and the container 10 in the contracted state gradually elongates,
Along with this, the seal portion 13 slides downward along the inclined surface 43. That is, the seal portion 13 can escape downward into the space (pocket) 45 formed between the inclined surface 43 and the auxiliary plate 44. At this time,
The upper end of the auxiliary plate 44 functions to guide the lower end of the container 10 into the space 45.
The upper end of the auxiliary plate 44 may be rounded (R) so as not to damage the container 10.

As shown in FIG. 9, when the container 10 is in the extended state, the seal portion 13 is housed in the space 45, and the lower end of the container 10 is curved.

By providing such an inclined surface 43 and an auxiliary plate 44, the lower end of the seal portion 13 comes into contact with the lower end of the container 10 when the container 10 is extended while regulating the position of the lower end of the container 10. Prevent or suppress the generation of resistance that hinders elongation. Thereby, as described above, the container 1
Since the pressure inside 0 is negative pressure and the amount of water to be electrolyzed by the pump 5 (the flow rate through the electrolytic cell 61) is prevented from decreasing, the pH and effective chlorine concentration of the electrolyzed water injected from the nozzle 7 are prevented. Of the electrolytic water can be suppressed, and the sterilizing and disinfecting ability of the electrolytic water can be stabilized.

FIGS. 10 and 11 are overall side views showing another embodiment of the electrolytic water supply device provided with the container holder of the present invention. Hereinafter, the embodiment shown in these figures will be described, but the description of the same items as in the above-described embodiment will be omitted.

The electrolytic water supply apparatus 1 shown in FIGS. 10 and 11 is the same as the above-described embodiment except that the configuration of the positioning portion 4 of the container holder 2 is different.

That is, the positioning portion 4 in the present embodiment is constituted by a coil-shaped spring 46 as an elastic member that deforms following the displacement of the lower end of the container 10 accompanying the extension of the container 10.

The spring 46 is in a contracted state as shown in FIG. 11 in a natural state (a state in which no stress is applied). The upper end of the spring 46 is fixed to the seal portion 13, and the lower end of the spring 46 is fixed to the base 21.

The length of expansion and contraction of the spring 46 (the difference in length between the natural state and the maximum expanded state) is preferably S or more, and more preferably 1.2S or more. The spring 46
May be made of metal or resin.

As shown in FIG. 10, when the container 10 is in the contracted state, the spring 46 is extended, and the seal portion 13 is urged downward by the elastic force of the spring 46. Thereby, the lateral movement of the lower end of the container 10 in FIG. 10 is restricted to some extent. The urging force (the force pulling the seal portion 13 downward) by the spring 46 may be relatively small, for example, about 5 to 1000 gf.

When the volume of the liquid in the container 10 decreases due to the generation and injection of the electrolyzed water, and the container 10 in the contracted state gradually elongates,
Accordingly, the seal portion 13 slides downward. That is, the seal portion 13 can be released into a space below the seal portion 13.

Then, as shown in FIG. 11, when the container 10 is in the extended state, the spring 46 is contracted, and the seal portion 13 is in the most lowered state.

By providing such a spring 46,
While restricting the position of the lower end of the container 10, when the container 10 extends, the lower end of the sealing portion 13 abuts to prevent or suppress the generation of a resistance force that hinders the elongation of the container 10. Thereby, as described above, the inside of the container 10 becomes a negative pressure,
Since the supply amount of the electrolyzed water by the pump 5 (the flow rate passing through the electrolytic cell 61) is prevented from decreasing, fluctuations in the pH and the effective chlorine concentration of the electrolyzed water injected from the nozzle 7 can be suppressed. In addition, the sterilizing and disinfecting ability of the electrolyzed water can be stabilized.
