Description

  The present invention relates to a liquid drug sustained-release tool that is suitably used for cleaning, polishing, protecting, and the like of hard surfaces.

  Conventionally, a liquid agent sustained release device comprising a liquid holding member impregnated with a liquid agent such as a cleaning agent or a polish, a flat bag-like container that hermetically contains the liquid holding member, and a liquid sustained release member (Wet sheets for cleaning) are known (for example, see Patent Documents 1 and 2 below). In the cleaning wet sheet 1 described in Patent Literatures 1 and 2, as shown in FIG. 6, the container 11 has an opening 13 on one surface, and the opening 13 is formed on the cleaning wet sheet 1. Before use, the sealing means 14 is in a sealed state, and the sealed state is released during use.

  In the cleaning wet sheet 1 described in Patent Documents 1 and 2, for example, as shown in FIG. 6A, the liquid sustained release member 20 is developed and accommodated on the developed liquid sustained release member 20. The body 11 is placed with the opening 13 facing upward. Thereafter, the sealing means 14 is peeled off from the container 11 to release the sealed state of the opening 13. Next, as shown in FIG. 6B, the container 11 is placed on the liquid sustained release member 20 with the container 11 turned over and the opening 13 facing downward. The reason for releasing the sealed state with the opening 13 facing upward is to prevent the liquid agent impregnated in the liquid holding member 12 from leaking out of the opening 13.

  Furthermore, the flap 23 in the liquid sustained release member 20 is folded back to the upper surface side of the head part in a cleaning tool (not shown) having a head part and a handle, and the cleaning wet sheet 1 is attached to the cleaning tool. And it can clean, applying a liquid agent to a flooring etc. in this state.

  Further, FIG. 6 of Patent Document 2 describes a cleaning wet sheet in a form in which a container having an opening is fixed to the liquid sustained release member in a state where the opening is opposed to the liquid sustained release member. Yes. Before use, the opening of the container is sealed by a band-shaped sealing means (seal 14) separate from the container. In the cleaning wet sheet of this form, the sealing state of the opening can be released by pulling out the belt-like seal 14 from the container, and cleaning can be performed while applying the liquid agent.

JP 2004-105395 A JP 2004-105710 A

  However, in the liquid agent sustained release tool (cleaning wet sheet) in which the container and the liquid sustained release member are separated as described above, the opening is sealed before use as described above. It is necessary to unravel the state and turn the container upside down and place it on the liquid sustained release member. In this case, the user mistakenly places the container on the liquid sustained release member with the opening facing upward. In many cases, the container is placed at a position shifted from a predetermined position of the liquid sustained-release member. Further, when the container could not be turned over smoothly, the liquid agent easily leaked from the opening, and the hands and the like were easily soiled by the adhesion of the liquid agent.

  In addition, in the liquid agent sustained release tool (cleaning wet sheet) in a form in which the container is fixed to the liquid sustained release member in a state where the opening is opposed to the liquid sustained release member, the belt-like seal is provided. Although it is recognized that 14 is adhered to the container so as to seal the opening, this adhesive may ooze or elute in the liquid agent of the liquid holding member. Further, since the strip-shaped seal 14 needs to be pulled out when the seal is released, the bonding strength by the adhesive cannot be excessively increased. Therefore, the certainty of securing the sealed state of the opening and releasing the sealed state is low.

  Therefore, according to the present invention, in the liquid drug sustained release device including the container for hermetically housing the liquid holding member and the liquid sustained release member, the container can be easily placed at a predetermined position of the liquid sustained release member during use. An object of the present invention is to provide a sustained-release device for a liquid agent that can prevent contamination of the hand or the like with the liquid agent and ensures the sealing state of the opening and the release of the sealing state.

  The present invention is a liquid agent sustained release device comprising a liquid holding member impregnated with a liquid agent, a flat bag-like container that hermetically accommodates the liquid holding member, and a liquid sustained release member, In use, the body is formed with an opening in a part thereof so as to release the sealed state, and the container body has a surface on which the opening is formed so that it can approach and separate from the liquid sustained release member. Furthermore, the object is achieved by providing a liquid agent sustained release device that is hinged to the liquid sustained release member only at a part of the flat peripheral edge of the container.

  According to the liquid drug sustained-release device of the present invention, in the liquid drug sustained-release tool provided with a container for hermetically housing the liquid holding member and the liquid sustained-release member, the container is easily placed at a predetermined position of the liquid sustained-release member during use. It can be placed, and it is hard to get your hands dirty with the liquid. Further, it is possible to ensure the sealed state of the opening and release the sealed state.

  Hereinafter, the liquid drug sustained release device of the present invention will be described based on a preferred embodiment thereof with reference to the drawings. In FIG. 1, the perspective view of the state which isolate | separated the container 11 and the liquid sustained release member 20 virtually about one Embodiment of the liquid agent sustained release tool of this invention is shown. FIG. 2 shows a longitudinal cross-sectional view (the liquid sustained release member 20 is disposed below) of the liquid drug sustained release device 1 in a state where the container 11 and the liquid sustained release member 20 are hinge-joined. Yes. The liquid agent sustained release device 1 of this embodiment is suitably used for cleaning and polishing a hard surface, for example, flooring.

As shown in FIGS. 1 and 2, the liquid agent sustained release device 1 of the present embodiment is a flat holding liquid housing member 12 impregnated with a liquid agent such as a cleaning agent or a polish, and a liquid holding member 12 hermetically sealed. A bag-like container 11 and a liquid sustained release member 20 are provided.
The liquid holding member 12 is made of, for example, a fiber material or a foam material, and is hermetically stored in a container 11 having a flat bag shape. The liquid holding member 12 has a rectangular shape slightly smaller than the container 11. The liquid holding member 12 is impregnated with a predetermined amount of a liquid agent such as a cleaning agent or a polish. Details of the liquid holding member 12 and the liquid agent will be described later.

  The container 11 includes a first liquid impermeable sheet 11a and a second liquid impermeable sheet 11b. Both liquid-impermeable sheets 11a and 11b have the same plan view shape, and have a vertically long rectangular shape. The container 11 is formed in a vertically long rectangular bag shape by joining two liquid-impermeable sheets 11a and 11b that are superposed on each other. If an adhesive is used for joining both the sheets 11a and 11b, the adhesive may be altered by the liquid impregnated in the liquid holding member 12, or the adhesive may be eluted into the liquid or ooze out. , 11b is preferably bonded by heat sealing or ultrasonic sealing.

  The two liquid-impermeable sheets 11a and 11b are not particularly limited as long as they are somewhat flexible and liquid-impermeable. For example, a thermoplastic resin film or a metal thin film such as aluminum is laminated on the film. Can be used. In particular, those formed from a laminate of a uniaxially stretched film layer and a metal foil are preferable. In the container 11 in the present embodiment, the stretching direction of the uniaxially stretched film layer coincides with the longitudinal direction of each liquid-impermeable sheet 11a, 11b. Both liquid-impermeable sheets 11a and 11b may be made of the same material or different materials.

  As shown in FIG. 2, of the two liquid impermeable sheets 11 a and 11 b, the first liquid impermeable sheet 11 a faces the liquid sustained release member 20 and comes into contact therewith. In the first liquid-impermeable sheet 11a, two opening guide regions 14 having a predetermined width are formed in parallel so as to extend in the longitudinal direction. The opening guide area 14 is formed by laminating a plurality of narrow sheet materials. As a result, the unsealing induction region 14 has a higher basis weight and higher strength than the other regions in the first liquid-impermeable sheet 11a.

  A uniaxially stretched film has a high mechanical strength in the stretching direction, but has a low mechanical strength in a direction perpendicular to the stretching direction. And in this embodiment, since the extending | stretching direction of a uniaxially stretched film corresponds with the longitudinal direction of the 1st liquid impervious sheet 11a as above-mentioned, the 1st liquid impervious sheet 11a is the The mechanical strength in the longitudinal direction is higher than the mechanical strength in the width direction. As a result, the first liquid-impermeable sheet 11 a can be easily torn along the opening guide region 14.

  The opening guide area 14 is formed over substantially the entire length of the container 11 in the longitudinal direction. The opening guide region 14 has a knob 15 connected to one end thereof. The knob 15 is a part that becomes a trigger for tearing the unsealing induction region 14 formed in the first impermeable sheet 11a. The knob 15 is formed from a partial region of the first liquid-impermeable sheet 11a. The knob 15 is formed by being in a non-bonded state in another region of the first liquid-impermeable sheet 11a.

  The container 11 can be formed with an opening 13 in a part thereof in use. The opening 13 is in a sealed state by a sealing means before the use of the liquid drug sustained release device 1 and is unsealed in use. In the present embodiment, as shown in FIG. 3, the first impermeable sheet including the opening guide region 14 by grasping the knob 15 by hand and pulling it toward the other end of the opening guide region 14. 11a is torn and an opening 13 is formed. That is, before the use of the liquid drug sustained release device 1, the first liquid-impermeable sheet 11a including the opening induction region 14 is not torn, and the liquid holding member 12 housed in the container 11 is The sealed state is maintained.

  On the other hand, prior to use of the liquid drug sustained release device 1, the knob 15 can be grasped by hand, and the opening guide region 14 can be torn and removed in the longitudinal direction of the container 11. As a result, the first liquid impervious sheet 11 a is formed with an opening 13 that substantially corresponds to the shape of the opening induction region 14. Then, the liquid agent impregnated in the liquid holding member 12 can be released to the outside of the container 11 through the opening 13. That is, in this embodiment, the sealing means is formed mainly by the opening guide region 14.

The area of each aperture 13 is preferably 5 to 13,000 mm ² from the viewpoint of controlling the degree of liquid agent release. For the same reason, the length of each opening 13 is preferably 5.0 to 500 mm, and the width of each opening 13 is preferably 1.0 to 52 mm. For the same reason, the opening with respect to the area of the first liquid-impermeable sheet 11a (excluding the area of the joint portion with the second liquid-impermeable sheet 11b for forming the container 11 in a bag shape). The ratio of the total area of the holes 13, that is, the opening ratio is preferably 5.0 to 80%.

  As described above, in the present embodiment, the liquid holding member 12 is kept sealed until just before use of the liquid drug sustained release device 1, and the tearing of the opening guide region 14 in the extending direction during use allows the liquid holding member 12 to be sealed. Solved for the first time. As a result, the liquid holding member 12 can be impregnated with a large amount of liquid without leaking or evaporation of the liquid.

  Next, the liquid holding member 12 will be described. Examples of the material of the liquid holding member 12 include a fiber material and a foam material. It is desirable that the liquid holding member 12 can be impregnated with a large amount of liquid agent and has excellent liquid agent release properties. As such materials, fiber aggregates such as bulky paper and nonwoven fabric are suitable, and airlaid nonwoven fabric, needle punched nonwoven fabric and the like are particularly preferable.

As a specific example of the fiber, either one or both of natural fiber and chemical fiber can be used. Examples of natural fibers include wood pulp. Examples of chemical fibers include regenerated fibers such as rayon and acetate, synthetic fibers such as polyethylene and polypropylene, polyolefin fibers such as polypropylene, polyester fibers, polyamide fibers such as nylon, and polyacrylonitonyl fibers.
Examples of the foam material include those formed by foaming or making porous by using a gas generated by a chemical reaction, injecting a low-melting-point solvent such as Freon gas, or injecting air. Specifically, polyurethane foam, polyolefin foam or the like is used.

The liquid holding member 12 has a density of 0.02 to 0.2 g / cm ³ , in particular 0.03 to 0.15 g, in order to increase the holding capacity of the liquid and to improve the release of the liquid at the time of applying the liquid. / Cm ³ is preferable. The basis weight of the liquid holding member 12 is preferably ²⁰ to 400 g / m ² , particularly preferably 60 to 200 g / m ² . When the basis weight is within this range, the retention capacity of the liquid agent can be made sufficiently large, and the workability of the liquid holding member 12 is also improved.

  The liquid holding member 12 is preferably impregnated with as much liquid as possible, but considering the case where the liquid is applied to a flooring using a single liquid agent sustained-release member in a general household, The weight of the liquid holding member 12 is about 300 to 3000%, particularly about 500 to 2500% of the weight of the liquid holding member 12 in the state before impregnation. The liquid holding member 12 is preferably one that is excellent in the sustained release of the liquid agent, and one that does not cause settling when impregnated with a large amount of the liquid agent is preferable.

  The air permeability of the liquid holding member 12 is preferably higher than the air permeability of the liquid sustained release member 20 in that the liquid agent release rate can be adjusted to an appropriate range.

  Further, as a preferable liquid holding member 12, a layer 12A having a multilayer structure and facing a hole 13 in the multilayer structure (for convenience of description, a reference numeral) is made of an airlaid nonwoven fabric mainly composed of synthetic fibers, and the layer The layer 12B adjacent to 12A is composed of paper or nonwoven fabric mainly composed of cellulosic fibers (not shown).

  In the liquid holding member 12 having such a multilayer structure, even when the liquid agent is impregnated at a high impregnation rate, the layer 12A mainly composed of synthetic fibers facing the apertures 13 includes cellulosic fibers adjacent to the layer 12A. Impregnating liquid retention is lower than that of the main layer 12B. Therefore, the liquid agent is impregnated and held in the layer 12B mainly composed mainly of cellulosic fibers. Therefore, the liquid agent can be prevented from scattering from the liquid holding member 12 when the container 11 is opened, and a large amount of liquid agent can be released at the initial stage of the liquid agent application, and as a result, the sustained release of the liquid agent is excellent. Incidentally, “mainly composed of synthetic fibers” means that the weight ratio of synthetic fibers is a majority. The same applies to “mainly composed of cellulosic fibers”.

  Next, the liquid sustained release member 20 will be described. The liquid sustained release member 20 once diffuses the liquid agent released from the liquid holding member 12 throughout the liquid sustained release member and releases them at a lower speed than the speed at which the liquid agent is released from the liquid holding member 12. By doing so, it is used for the purpose of gradually releasing the liquid agent in a predetermined range from the initial stage to the final stage of the application on the application target surface having a large area.

  The liquid sustained release member 20 may be composed of a sheet laminate (multi-ply), and may be formed from a single sheet (single ply). As shown in FIG. 2, the inner layer sheet 21 and the surface sheet 22 are composed of two plies. Both sheets 21 and 22 are overlapped and integrated by joining both side edges in the longitudinal direction of the inner layer sheet 21 to the surface sheet 22. The inner layer sheet 21 has a rectangular shape that is substantially the same size as the container 11. The length of the top sheet 22 (the length along the longitudinal direction of the container 11) is substantially the same as the length of the inner layer sheet 21. The top sheet 22 extends from both side edges in the longitudinal direction of the inner layer sheet 21 to both sides, and forms a pair of flaps 23 and 23 in the extended region. The purpose of use of the flap 23 will be described later.

  When the liquid sustained release member 20 is composed of a laminated body of the inner layer sheet 21 and the top sheet 22 as in the present embodiment, the operability at the time of applying the liquid agent is further improved, and the inner layer sheet 21 is protected. There is. There is also the advantage that the release of the liquid is further controlled.

Regardless of whether the liquid sustained-release member 20 is composed of a single sheet (single ply) or a sheet laminate (multi-ply), it exhibits a sustained-release performance that uniformly releases a large amount of liquid agent. Therefore, it is necessary to prevent excessive retention of the liquid agent by the liquid sustained release member 20. From this viewpoint, the basis weight of the liquid sustained release member 20 is preferably 20 to 350 g / m ² , and particularly preferably 40 to 200 g / m ² .

  As a raw material of the liquid sustained release member 20, a sheet material in which the liquid agent is favorably diffused in the plane direction is preferable. Examples of such a sheet material include fiber sheets such as wet papermaking paper, spunlace nonwoven fabric, and meltblown nonwoven fabric. In the case of wet papermaking, the control of the diffusibility is adjusted by the type of fiber, the beating degree, wet pressure (pressure before drying), calendering (pressure after drying), filler addition, and the like. Examples of the fiber include softwood pulp and hardwood pulp, various modified pulp, rayon fiber, thermoplastic fiber, and the like. Among these, when a fiber having a small fiber diameter or a fiber having a short fiber length is used, the size (pore diameter) of the gap between the sheets formed between the fibers becomes small, and a desired diffusibility is easily obtained. Similarly, desired diffusibility can be easily obtained by increasing beating or increasing the calendar processing pressure. An increase in filler is also effective.

  In the case of a spunlace nonwoven fabric, for example, it is easy to obtain desired diffusibility by using hydrophilic fibers such as cotton or rayon, using fibers having a small fiber diameter, or making the entangled state highly entangled. In the case of forming irregularities on the liquid sustained release member 20 by embossing described later, preferably 5 to 95% by weight, more preferably 10 to 75% by weight of thermoplastic fiber is added to perform heat embossing. It becomes easy to maintain the convex shape even when wet.

The inner layer sheet 21 and the top sheet 22 may be formed from the same material, or may be formed from different materials. The basis weight of the surface sheet 22, from the viewpoint that unnecessary cost is not applied fulfills sheet strength required for liquid coating, preferably from 10 to 100 g / m ^2, particularly preferably 20 to 80 g / m ^2.

  The inner layer sheet 21 in the present embodiment has a large number of convex portions on the surface. As a result, the contact area between the inner layer sheet 21 and other sheets positioned on the upper and lower surfaces thereof is reduced. As a result, it is possible to reduce the excessive release of the liquid agent that is likely to occur at the initial stage of the liquid application, and to further improve the sustained release performance. This convex portion is preferably formed over the entire sheet, and is formed, for example, by embossing. In particular, formation by steel match embossing is preferable from the viewpoint of maintaining the shape in a wet state. As the convex portion, for example, a rib shape or a dot shape is used.

  The inner layer sheet 21 in the present embodiment has a concave portion between the convex portions, and is unevenly shaped over the entire sheet. The concave portions and the convex portions are alternately arranged in the longitudinal direction and the width direction of the sheet. The shape of the concave portion is a shape obtained by inverting the convex portion. The shape of the convex part formed in the inner layer sheet 21 can be made the same as the shape of the convex part described in JP-A-9-131288.

  When the convex portion is formed on the inner layer sheet 21 by steel match embossing, the contact area with other sheets located on the upper surface or the lower surface of the inner layer sheet 21 is 5 to 60% with respect to the entire area of the inner layer sheet 21. Further, it is preferable that the convex portion is formed (this value is referred to as a contact area ratio). The height of the protrusion is preferably 0.2 to 10 mm, and the cross-sectional shape of the protrusion is preferably wavy. The contact area ratio is measured by the following method.

1) Spray paste (Sumitomo 3M Co., Ltd., trade name “55”) is sprayed uniformly on the measurement surface of the inner layer sheet at a basis weight of about 0.0006 g / cm ² .
2) Seven types of JIS test dust (Kanto loam layer, fine particles) are spread thinly and evenly on a flat plate.
3) The measurement surface of the inner layer sheet coated with the spray paste is superimposed on the surface of the plate on which seven types of JIS test dust are dispersed. An acrylic flat plate is overlaid thereon, and a weight is placed so that a load of 500 g is combined with the weight of the acrylic flat plate, and a load is applied for 5 minutes. Thereby, a sample for measurement is obtained.
4) Image analysis of the obtained sample is performed, and the ratio of the area of the portion contaminated with 7 kinds of JIS test dust on the surface in contact with the plate is calculated, and this is used as the contact area ratio.

  The top sheet 22 becomes the liquid agent application surface of the liquid agent sustained release tool 1 at the time of applying the liquid agent, and is used for the purpose of improving the operability at the time of applying the liquid agent and protecting the inner layer sheet 21. It is also used for the purpose of further controlling the release of the liquid agent. In order to improve the operability at the time of applying the liquid agent, the top sheet 22 in the present embodiment has a large number of convex portions on the liquid agent application target surface side, like the inner layer sheet 21. As a result, the contact area with the surface to which the liquid agent is applied decreases, the friction during liquid application decreases, and the operability of liquid application can be improved. The description regarding the inner layer sheet 21 is also applied to the top sheet 22 as appropriate.

  Next, the hinge joining form of the container 11 and the liquid sustained release member 20 will be described. The container 11 is joined to the liquid sustained-release member 20 only at a part of the peripheral edge of the flat container 11 so that the surface on which the opening 13 is formed can be moved toward and away from the liquid sustained-release member 20. . In the present embodiment, the vertically long rectangular container 11 is joined to the liquid sustained release member 20 only at a long side edge (long side edge) 11c which is one side of the container. The surface of the container 11 in which the opening 13 is formed (that is, the surface on the first liquid-impermeable sheet 11a side) is separable from the inner layer sheet 21 of the liquid holding member 12. . In a state where the container 11 is in contact with the inner layer sheet 21, the container 11 and the inner layer sheet 21 overlap with each other in an almost identical arrangement.

  There is no restriction | limiting in particular in the means to hinge-join the peripheral part of the container 11 and the liquid slow release member 20, For example, an adhesive tape, an adhesive agent (hot melt adhesive etc.), and a heat seal can be used. In the present embodiment, the adhesive tape 4 is used to join the entire region of the long side edge 11 c of the container 11 and the vicinity of both side edges in the longitudinal direction of the inner layer sheet 21 in the liquid sustained release member 20. On the other hand, the container 11 and the liquid sustained release member 20 are not joined at other portions. Therefore, the container 11 is rotatable in the direction approaching or separating from the liquid sustained release member 20 with the adhesive tape 4 as a rotation fulcrum.

  The long side edge portion 11c of the container 11 and the liquid sustained-release member 20 are hinged to each other so that the container 11 has a short length as long as the rotation of the container 11 relative to the liquid sustained-release member 20 is not hindered. It includes a form in which the side edge portion (side edge portion with a short length. Front and rear edge portions in another way) is slightly joined to the liquid sustained release member 20.

  Next, the liquid agent impregnated in the liquid holding member 12 will be described. As the liquid agent, for example, a cleaning agent, a polishing agent, or the like is used. It is preferable that the cleaning agent contains water as a medium and contains a surfactant, an alkali agent, and the like. For example, dirt that cannot be removed by dry cleaning such as dirt dust, sebum, and oil dirt is dissolved and wiped off. It is used for the purpose. The polish is an agent for the purpose of polishing and protecting flooring. Polishing agents can be broadly classified into those containing a large amount of surfactants and so-called wax agents containing almost no surfactant. The polish may have a cleaning function.

  The viscosity of the liquid at 25 ° C. is preferably 1 to 20 mPa · s, particularly 2 to 10 mPa · s, from the viewpoint of good wiping and finishing properties. The viscosity of the liquid agent may be slightly higher as long as the liquid agent can be impregnated and held in the liquid sustained release member 20. The viscosity is measured using a B-type viscometer (rotor No. 1, 60 rpm) of Tokyo Keiki Co., Ltd.

  The cleaning agent can contain a disinfectant in addition to the aforementioned components. Thereby, in addition to the cleaning effect, a sterilizing effect can be imparted to the cleaning agent. Disinfectants include hydrogen peroxide, hypochlorous acid, sodium hypochlorite, quaternary ammonium salts, sodium benzoate, sodium paraoxybenzoate, natural disinfectants, etc. From the viewpoint of disinfection performance, quaternary ammonium salts, natural disinfectant polylysine and the like are preferably used. The disinfectant is preferably contained in the cleaning agent in an amount of 0.005 to 2% by weight, particularly 0.01 to 1% by weight, from the viewpoint of the balance between the disinfecting effect and the reduction of skin irritation.

Furthermore, the cleaning agent may contain a fragrance, an antifungal agent, a coloring matter (dye or pigment), a chelating agent, a wax agent, or the like as necessary.
Water, which is a medium for the cleaning agent, is preferably contained in the cleaning agent in an amount of 50 to 99.9% by weight, particularly 80 to 99% by weight, from the viewpoint of the finish of the surface to be cleaned.

One usage method of the liquid drug sustained release tool 1 of this embodiment is demonstrated. When using the liquid drug sustained release device 1 of the present embodiment, for example, as shown in FIG. 2A, the liquid sustained release member 20 is deployed in a state where the container 11 is disposed on the container 11. Next, as shown in FIGS. 2 (b) and 4 (a), the opening 11 is formed in the housing 11 by rotating the housing 11 by 180 ° using the adhesive tape 4 as a pivot point. The surface (the surface on the first liquid-impermeable sheet 11a side) faces upward.
In this state, the knob 15 in the container 11 is gripped by hand and pulled toward the other end of the opening guide region 14 to tear and open the first impermeable sheet 11a including the opening guide region 14. Hole 13 is formed (see FIG. 3).

Thereafter, as shown in FIG. 4 (b), the adhesive tape 4 is pivoted in the direction opposite to the previous pivoting while taking care not to leak the liquid from the container 11 through the opening 13. The container 11 is rotated 180 ° (turned over), and the surface of the container 11 in which the opening 13 is formed is brought into contact with the inner layer sheet 21 of the liquid sustained release member 20. The liquid drug sustained release tool 1 in this state is used by being attached to the sustained release working tool 30 shown in FIG.
A sustained release working tool 30 shown in FIG. 5 includes a flat head portion 31 to which the liquid agent sustained release tool 1 of this embodiment can be attached, and a rod-shaped handle 33 connected to the head portion 31 via a universal joint 32. Has been. The head portion 31 has a rectangular shape that is substantially the same size as the container 11.

  The liquid agent sustained release device 1 is attached to the head portion 31 such that the second liquid-impermeable sheet 11b side (the surface side where the opening 13 is not formed) of the container 11 faces the lower surface of the head portion 31. Is done. Next, the flaps 23, 23 in the liquid sustained release member 20 are folded back to the upper surface side of the head portion 31. Further, the flap 23 is pushed into a plurality of flexible pieces 34 having radial slits in the head portion 31. Thereby, the liquid agent sustained release tool 1 can be fixed to the head portion 31 of the sustained release work tool 30. And a liquid agent can be apply | coated to a flooring etc. in this state.

  According to the liquid drug sustained release device 1 of the present embodiment, the following effects are exhibited. In the liquid drug sustained release device 1 of the present embodiment, the container 11 has a part (long) of the peripheral portion of the container 11 such that the surface on which the opening 13 is formed is freely movable toward and away from the liquid sustained release member 20. Only the side edge portion 11c) is joined to the liquid sustained release member 20. Therefore, the container 11 in which the liquid holding member 12 is stored can be easily rotated with respect to the liquid holding member 12 with the adhesive tape 4 serving as a joining means as a rotation center.

  Therefore, for example, as in the above-described one method of use, the container 11 is placed on the liquid sustained release member 20 so that the opening 13 faces upward, and in this state, the sealing state of the opening 13 is easily achieved. Can be solved. Thereafter, with the adhesive tape 4 as the center of rotation, the container 11 can be easily rotated so that the opening 13 abuts the liquid sustained release member 20.

  As a result, the container 11 can be easily placed at a predetermined position of the liquid sustained-release member 20 during use, as compared with a liquid drug sustained-release tool in which the container and the liquid sustained-release member are separated. In addition, the container 11 in which the opening 13 is formed is easily turned over smoothly, and the hand or the like is not easily soiled with the liquid agent. Furthermore, the opening 13 of the container 11 has an adhesive before use, as compared to a liquid drug sustained release device in which the container is fixed to the liquid sustained release member with the opening facing the liquid sustained release member. Therefore, the opening 13 can be reliably formed by tearing while improving the hermeticity of the liquid agent in the container 11. In this way, it is possible to ensure the sealed state of the opening 13 and release the sealed state.

As mentioned above, although the liquid agent sustained release tool of this invention was demonstrated based on preferable one Embodiment, the liquid agent sustained release tool of this invention is not restrict | limited to the said embodiment.
For example, the position of the hinge joint with the liquid sustained release member 20 in the container 11 is not limited to the entire region of the long side edge 11c as in the above embodiment, and may be only a partial region of the long side edge 11c. It may be a side edge (front / rear edge). Furthermore, the hinge joining position may be on the outside of the surface of the liquid sustained release member 20 facing the head portion 31 of the sustained release work tool 30 or on the inside of the opposed surface. The joint form of the hinge joint between the container 11 and the liquid sustained-release member 20 may be a point-like (two points to a plurality of points) joint or a linear joint.

  In the embodiment, the opening induction region 14 is formed in the container 11 as the sealing means for the opening 13, but as other sealing means, a sheet-like sealing member is heat-sealed to the container 11. Means for joining by fusion such as ultrasonic sealing can also be used.

For the purpose of protecting the liquid sustained release member 20 and improving the operability of the liquid agent sustained release tool 1, another sheet may be stacked on the outer surface of the liquid sustained release member 20 separately from the liquid sustained release member 20. The liquid sustained release member 20 can be formed from one sheet (single ply).
In order to further prevent the liquid reservoir from being generated in the container 11, the container 11 may be divided into a plurality of compartments, and the liquid holding member 12 may be arranged in each compartment.

  The liquid agent sustained release device of the present invention is particularly suitable for applying a liquid agent to flooring, but can also be used for applying a liquid agent to other hard surfaces such as automobile bodies and leather shoes. Moreover, the liquid agent sustained release tool of this invention can also be used for application | coating of liquid agents, such as another wet cleaning and polish.
