Description

[Technical Field]

[0001] The present invention relates to a liquid spraying device for spraying various liquids. [Background technology]

[0002] A liquid spraying device for spraying liquids such as pesticides and herbicides has a configuration as described in Patent Document 1. The liquid spraying device in Patent Document 1 has a battery-powered spraying tool and a container that contains the liquid to be sprayed. The spraying tool and the container are connected by a flexible hose. The container also has a dip tube for sucking up the liquid in the container.

[0003] These types of containers are generally made of plastic with enough rigidity to prevent them from easily deforming when handled, and are equipped with handles so that the user can carry them. This allows the user to hold the sprayer in one hand and the container handle in the other while moving, making it easy to spray the liquid over a wide area. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2015 / 038744 Pamphlet Summary of the Invention [Problem to be solved by the invention]

[0005] In this type of liquid spraying device, when the liquid in the container runs out, it is preferable to be able to purchase a so-called "refill" package and refill the liquid so that the container can continue to be used.

[0006] Furthermore, in recent years, from the viewpoint of reducing waste plastic, there has been a tendency to avoid discarding the above-mentioned rigid plastic containers, and for this reason, it is considered preferable to use containers that use even less plastic as refill packaging, specifically, those made by molding film or sheet-like materials into a bag shape (so-called pouches).

[0007] However, in the field of agricultural chemicals, for example, such refilling practices are subject to some restrictions.

[0008] Even if such regulations do not exist, the refilling process is not only time-consuming but also a source of trouble such as spillage of the liquid or contact with hands during refilling. In particular, when the container of the refill package is a pouch, it is prone to deformation during the refilling process, making it prone to the above-mentioned troubles.

[0009] Therefore, the inventors of the present application considered whether it would be possible to use the pouch itself as the spraying container in an electric sprayer, rather than using a rigid plastic container. If the pouch itself could be used as the spraying container, the work of refilling would be unnecessary, which would not only solve the problems that arise from refilling, but would also be advantageous from the perspective of reducing plastic, as it would make it possible to do away with the rigid plastic container itself, such as the container in Patent Document 1.

[0010] However, the inventors of the present application have found that simply replacing the rigid plastic container of Patent Document 1 with a pouch causes various problems, as described below. 1. As the liquid level decreases, negative pressure builds up inside the pouch, causing it to collapse, which can lead to bending of the dip tube. As a result, the dip tube is unable to absorb all the liquid, resulting in residual liquid. 2. When disposing of the pouch, the dip tube inside the pouch gets in the way, making it difficult to roll or fold the pouch. Furthermore, the dip tube itself becomes plastic waste, which is undesirable from the perspective of waste reduction. While it is possible to remove the dip tube and reuse it, this adds work to the user, and problems such as the liquid getting on the user's hands when inserting or removing the dip tube can arise. 3. Ordinary pouches do not have handles, so they cannot be held by hand like the container of Patent Document 1. Even if a handle were provided on the pouch, there would be a problem with durability.

[0011] As a result of extensive research, the present inventors have found that the above problems can be solved by using the pouch upside down, and have thus completed the present invention. [Means for solving the problem]

[0012] A liquid spraying device according to one aspect of the present disclosure includes a bag body that contains a liquid and has an outlet through which the contained liquid flows, an electric sprayer that can continuously spray the liquid, and a flexible hose that connects the outlet of the bag body to an inlet of the electric sprayer. In this liquid spraying device, the outlet is positioned below the bag body when the electric sprayer sprays the liquid.

[0013] With this configuration, the liquid is contained in the bag, thereby reducing the amount of plastic used compared to conventional spraying devices that use rigid plastic containers. When the electric sprayer begins operation, the liquid contained in the bag flows through a hose from an outlet at the bottom of the bag, is drawn into the suction port of the electric sprayer, and is then sprayed from the electric sprayer. Because the outlet of the bag is located at the bottom during spraying, the dip tube provided in conventional sprayers is not required. As a result, even if the liquid inside the bag decreases and the bag collapses due to negative pressure, the dip tube does not break. Therefore, there is no problem with residual liquid, and the liquid inside the bag can be sprayed to the last drop. Furthermore, the absence of a dip tube does not get in the way when disposing of the bag, and there is no need to insert or remove the dip tube, making it easier for users to handle.

[0014] In another aspect of the present disclosure, the outlet faces downward when the electric sprayer sprays liquid.

[0015] In other words, because the outlet of the bag faces downward, the flexible hose connected to the outlet hangs down smoothly, making the hose between the electric sprayer and the outlet less likely to bend, and allowing for smooth spraying.

[0016] A bag body according to another aspect of the present disclosure is a self-standing pouch having a top sheet, a back sheet, and a bottom sheet, with the bottom sheet welded to the top sheet and the back sheet. The outlet is provided on the opposite side of the bag body from the bottom sheet in the vertical direction. Handles are attached to mounting holes formed in the welded portion between the bottom sheet and the top sheet and the welded portion between the bottom sheet and the back sheet. The handles are positioned at the top of the bag body when spraying liquid with the electric sprayer.

[0017] In another aspect of the present disclosure, a handle opening may be formed that penetrates the welded portion between the bottom sheet and the top sheet and the welded portion between the bottom sheet and the back sheet in the thickness direction, in which case the handle opening is positioned at the top of the bag when spraying liquid with the electric sprayer.

[0018] That is, in a self-standing pouch, the bottom sheet, top sheet, and back sheet are welded together to form a bottom gusset, which is as thick as four sheets and is therefore very strong. Therefore, by attaching a handle to this strong portion or forming an opening for the handle, it is possible to prevent the bag from tearing during application and to provide high durability. The handle opening is an opening large enough to fit at least one finger of the user's hand, and multiple openings may be provided.

[0019] In another aspect of the present disclosure, the mounting holes are formed on both widthwise sides of the bag body, and the handle has a first mounting portion attached to the mounting hole formed on one widthwise side of the bag body, a second mounting portion attached to the mounting hole formed on the other widthwise side of the bag body, and a main body portion extending from the first mounting portion to the second mounting portion.

[0020] With this configuration, the first and second attachment portions of the handle are attached to attachment holes that are spaced apart in the width direction of the bag, so the bag is stable when the user holds the handle, improving operability when spraying liquid. [Effects of the Invention]

[0021] As explained above, by positioning the outlet at the bottom of the bag body when spraying liquid with an electric sprayer, it is possible to spray without leaving any liquid behind, while reducing the amount of plastic used, without using a rigid plastic container as the spraying container, and it is also possible to eliminate the need for a dip tube, making it easier for the user to handle.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the present invention, its applications, or its uses.

[0024] FIG. 1 shows a liquid spraying device A according to an embodiment of the present invention. The liquid spraying device A includes a bag 1 for containing a liquid, an electric sprayer 80 capable of continuously spraying the liquid, and a flexible hose 70 connecting the bag 1 and the electric sprayer 80. As shown in FIG. 2 and other figures, the bag 1 is a so-called pouch. FIG. 2 is a front view of the bag 1. Examples of liquids contained in the bag 1 include herbicides, pesticides, fertilizers, water, disinfectants, fungicides, mildew inhibitors, detergents, insecticides (pesticides), pest repellents, paints, lubricants, and solvents, but are not limited to these. Various types of sprayable liquids may also be used. Furthermore, the liquid contained in the bag 1 may be one of the above-mentioned examples, or a mixture of any two of them.

[0025] The internal volume of the bag 1 can be set, for example, in the range of 100 ml to 5000 ml. As will be described later, since the bag 1 is to be held by the user, the internal volume can be set so that it is, for example, 5 kg or less when filled with liquid, or, taking into account long-term use, the internal volume can also be set so that it is 1 kg or less when filled with liquid. In consideration of stability during use, the bag 1 is preferably long in the vertical direction, but this is not a limitation, and the width dimension may be longer than the vertical dimension.

[0026] As shown in Figures 2 and 3, the bag 1 has a top sheet 10, a back sheet 11, a bottom sheet 12, and an outlet-forming member 14. In this way, the bag 1 is constructed by combining multiple sheets 10-12, and the bag 1 contains liquid B. This reduces the amount of plastic used compared to conventional examples in which a rigid plastic container is used as a spray container. The top sheet 10, the back sheet 11, and the bottom sheet 12 are made of, for example, flexible resin sheets, and may be made of, for example, a single layer of film made of nylon, polyethylene terephthalate (PET), polypropylene, polyethylene, etc., or may have a multi-layer structure in which any two or more of these films are laminated together. The top sheet 10, the back sheet 11, and the bottom sheet 12 may also be sheets having a layer made of, for example, aluminum foil. In this case, the sheets may have a multi-layer structure in which aluminum foil is laminated between a top layer and a back layer made of resin. Alternatively, a sheet with the desired properties, thickness, and strength may be obtained by combining a metal vapor deposition layer, various resin layers, adhesive layers, etc., and the obtained sheet may be used to form the top sheet 10, back sheet 11, and bottom sheet 12. Since the top sheet 10, back sheet 11, and bottom sheet 12 have heat-sealing properties as described below, for example, a structure in which a base material layer and a thermoplastic resin layer are laminated can be used. The base material layer and the thermoplastic resin layer can be laminated and integrated by, for example, melt extrusion or dry lamination.

[0027] The thickness of the top sheet 10, back sheet 11, and bottom sheet 12 can be set to any thickness, and can be set to a thickness that will not stretch even when stored for a long period of time while containing liquid, and will not tear even when subjected to a slight impact. Specifically, the thickness of the top sheet 10, back sheet 11, and bottom sheet 12 can be, for example, 50 μm or more, or 100 μm or more, and the upper limit of the thickness of the top sheet 10, back sheet 11, and bottom sheet 12 can be 500 μm or less. The top sheet 10, back sheet 11, and bottom sheet 12 may all be made of the same sheet, or different sheets may be combined depending on the location.

[0028] The top sheet 10, back sheet 11, and bottom sheet 12 have heat-sealing properties. Heat-sealing properties are achieved by, for example, stacking the top sheet 10 and back sheet 11 in the thickness direction, tightly adhering them together, heating them to a temperature above the melting point of the resin at the contact surface, and then lowering the temperature to the hardening point of the resin, thereby welding the top sheet 10 and back sheet 11 together and preventing the inflow or outflow of gas or liquid. In other words, the top sheet 10, back sheet 11, and bottom sheet 12 can be joined together airtightly or liquidtightly by a heat-sealing method. The various conditions and heat-sealing devices used for heat-sealing are well known.

[0029] Figures 2 and 3 show the bag 1 in its unused position when stored or transported to a store, etc., and this position is referred to as the unused position. Meanwhile, Figures 6 and 8 show the position when a liquid is being sprayed by the electric sprayer 80, with the bag 1 in its unused position turned upside down (top and bottom). This position is referred to as the used position. The shape of the bottom of the bag 1 in its unused position is designed so that it will remain upright without tipping over when placed on a horizontal surface, for example. Such a bag 1 can be called a freestanding pouch or a standing pouch. The bag 1 can also be called a pouch, a storage bag, a bag-like container, etc. Because the top sheet 10, the back sheet 11, and the bottom sheet 12 are made of flexible resin sheets, the bag 1 can freely change shape, but because each of the sheets 10-12 is almost inelastic, the bag 1 does not stretch or deform even when filled with liquid.

[0030] As shown in Figures 2 and 3, when the bag body 1 is in the unused position, the outlet-forming member 14 is positioned at the top of the bag body 1. The top sheet 10 is a member that forms the front side (front surface) of the bag body 1, and is set to have a length in the up-down direction that is longer than the length in the width direction (left-right direction in Figures 2 and 3). The back sheet 11 is a member that forms the back side (rear surface) of the bag body 1, and has a shape similar to that of the top sheet 10. The front and rear surfaces are defined merely for the sake of convenience of explanation, and the side shown in Figure 2 may be the rear surface. The front surface may also be called the front surface, and the rear surface may also be called the rear surface.

[0031] As shown in Fig. 2, the bag 1 has a top seal portion 20, a left seal portion 21, a right seal portion 22, a front bottom seal portion 23, and a back bottom seal portion 24 (shown in Figs. 3 and 4). The top seal portion 20, the left seal portion 21, and the right seal portion 22 are welded portions between the top sheet 10 and the back sheet 11. The top bottom seal portion 23 is a top weld portion where the top sheet 10 and the bottom sheet 12 are welded, and the back bottom seal portion 24 is a back weld portion where the back sheet 11 and the bottom sheet 12 are welded.

[0032] That is, the upper part of the top sheet 10 and the upper part of the back sheet 11 are welded together by heat sealing to form an upper seal part (upper weld part) 20. The left side of the top sheet 10 and the left side of the back sheet 11 are also welded together by heat sealing to form a left side seal part (left side weld part) 21. The right side of the top sheet 10 and the right side of the back sheet 11 are also welded together by heat sealing to form a right side seal part (right side weld part) 22. The vertical dimension of the upper seal part 20, the horizontal dimension of the left side seal part 21, and the horizontal dimension of the right side seal part 22 can be, for example, about 5 mm.

[0033] 3, the bottom sheet 12 is disposed so as to extend in the depth direction of the bag 1 when liquid B is contained therein. The front portion 12a of the bottom sheet 12 is folded downward, and the front portion 12a of the bottom sheet 12 and the lower portion of the top sheet 10 are welded together by a heat sealing method to form a front bottom seal portion 23. The back portion 12b of the bottom sheet 12 is also folded downward, and the back portion 12b of the bottom sheet 12 and the lower portion of the back sheet 11 are welded together by a heat sealing method to form a back bottom seal portion 24.

[0034] The portion of the bottom sheet 12 between the front portion 12a and the back portion 12b extends in the depth direction of the bag body 1, so that the depth dimension of the bottom of the bag body 1 is longer than the depth dimension of the upper portion. This allows the bag body 1 to stand stably when filled with liquid. Furthermore, because the left side of the top sheet 10 and the left side of the back sheet 11 are welded to each other, the depth dimension of the bottom sheet 12 becomes shorter as it approaches the left end of the bag body 1. Similarly, because the right side of the top sheet 10 and the right side of the back sheet 11 are welded to each other, the depth dimension of the bottom sheet 12 becomes shorter as it approaches the right end of the bag body 1.

[0035] As shown in FIG. 2, the vertical dimension of the front bottom seal portion 23 is shortest at the center and increases toward the left and right. Therefore, the left and right sides of the front bottom seal portion 23, which are the welded portions between the lower part of the topsheet 10 and the front portion 12a of the bottom sheet 12, are designated as expanded front seal portions 23a. The vertical dimension of the expanded front seal portion 23a can be, for example, 10 mm or more, or 20 mm or more. The vertical dimension of the portion of the front bottom seal portion 23 other than the expanded front seal portion 23a can be, for example, less than 10 mm or 5 mm or less, and may be the same as the vertical dimension of the top seal portion 20.

[0036] Similarly, the vertical dimension of the back bottom seal 24 is shortest at the center in the left-right direction and is set to increase toward the left and right. Therefore, the left and right sides of the back bottom seal 24, which is the welding portion between the lower part of the back sheet 11 and the back part 12b of the bottom sheet 12, are respectively made into extended back seals 24a (shown in Figure 4).

[0037] The provision of the expanded front seal portion 23a and the expanded back seal portion 24a improves the strength of the lower corners of the bag 1. This prevents the bag 1 from bursting when the internal pressure suddenly increases, for example, when the sealed bag 1 is dropped. In essence, the expanded front seal portion 23a and the expanded back seal portion 24a are reinforcing portions, which may be referred to as bottom gussets, for example. The expanded front seal portion 23a and the expanded back seal portion 24a may be provided as needed. When storing liquid B inside the bag 1, the left side seal portion 21, the right side seal portion 22, the front bottom seal portion 23, and the back bottom seal portion 24 are formed, leaving only the top open. Liquid B is then stored from above, and the top seal portion 20 is then formed to seal the bag.

[0038] As shown in FIG. 2, the left side of the upper portion of the bag body 1 is cut out at an angle. Because the left side of the upper portion of the bag body 1 is cut out at an angle, the left side of the upper portion of the bag body 1 forms an inclined portion 10a that extends downward as it approaches the left end. An outlet-forming member 14 is provided on the inclined portion 10a. The outlet-forming member 14 is a resin molded body obtained by molding and solidifying a synthetic resin. Specifically, the outlet-forming member 14 is made of a resin material that is welded to, for example, the top sheet 10 and the back sheet 11, and has a base portion 14a and a tubular portion 14b that protrudes from the base portion 14a to the outside of the bag body 1. The base portion 14a is formed in a cylindrical shape and is disposed between the top sheet 10 and the back sheet 11. The outer peripheral surface of the base portion 14a is welded to both sheets 10, 11, thereby sealing the gap between the outer peripheral surface of the base portion 14a and both sheets 10, 11 and fixing the base portion 14a to both sheets 10, 11. A passage formed inside the base portion 14a communicates with the interior of the bag body 1. Furthermore, the passage formed inside the base portion 14a and the interior of the cylindrical portion 14b communicate with each other.

[0039] The axis of the cylindrical portion 14b is inclined with respect to the vertical line, and the inclination angle is set to, for example, 30° or more, or 40° or more. The inclination angle of the axis of the cylindrical portion 14b with respect to the vertical line is set to, for example, 80° or less, or 70° or less. The axis of the cylindrical portion 14b may extend in the vertical direction.

[0040] As shown in FIG. 5, an outlet 14c through which the liquid contained in the bag body 1 flows out is formed on the tip surface of the protruding direction of the cylindrical portion 14b. A spirally extending screw thread 14d is formed on the outer peripheral surface of the cylindrical portion 14b. As shown in FIG. 2, a cap 15 is attached to the cylindrical portion 14b when not in use. A thread groove (not shown) is formed on the inner peripheral surface of the cap 15, and the thread groove is threadedly engaged with the screw thread 14d of the cylindrical portion 14b to tighten the cap 15, thereby closing the outlet 14c. On the other hand, before use, the outlet 14c can be opened by loosening and removing the cap 15. The cap 15 may be configured to close the outlet 14c by being press-fitted into the outlet 14c.

[0041] Because the tubular portion 14b is provided at the top of the bag body 1, the outlet 14c is provided on the opposite side of the bottom sheet 12 in the vertical direction. Furthermore, because the tubular portion 14b protrudes upward, the outlet 14c, which opens at the tip end surface of the tubular portion 14b in the protruding direction, faces upward. In particular, in this embodiment, the tubular portion 14b protrudes diagonally upward to the left, so the outlet 14c also faces diagonally upward to the left. If the tubular portion 14b protrudes vertically upward, the outlet 14c also faces vertically upward. Furthermore, the tubular portion 14b may protrude diagonally upward to the right, in which case the outlet 14c also faces diagonally upward to the right. In other words, the outlet 14c may face directly upward or diagonally upward. Furthermore, the outlet 14c may be located on the right side of the bag body 1 or in the center in the horizontal direction. The inclined portion 10a may be provided on the right side, or the inclined portion 10a may be omitted.

[0042] (Handle structure) In this embodiment, a handle 60 is detachably attached to the bottom of the bag 1. The handle 60 is held by the user during use and can also be called a grip. That is, as shown in FIG. 2, mounting holes 23b for mounting the handles 60 are formed on both the left and right sides of the bag 1. The left mounting hole 23b is formed to penetrate the left expanded front seal portion 23a in the thickness direction. The right mounting hole 23b is formed to penetrate the right expanded front seal portion 23a in the thickness direction. The shape of the mounting holes 23b is not particularly limited, but can be, for example, circular.

[0043] Similar to the front side, mounting holes 24b for attaching handles 60 are formed on both the left and right sides of the bag body 1 on the back side. The left mounting hole 24b is formed to penetrate the left rear-side expanded seal portion 24a in the thickness direction. The right mounting hole 24b is formed to penetrate the right rear-side expanded seal portion 24a in the thickness direction. As shown in FIG. 4, the front-side mounting hole 23b and the rear-side mounting hole 24b are at the same height and are positioned at the same left-right direction. Therefore, when the bag body 1 is viewed from the front or rear side, the front-side mounting hole 23b and the rear-side mounting hole 24b are positioned so as to overlap. Note that the front-side mounting hole 23b and the rear-side mounting hole 24b may overlap completely or partially.

[0044] 6, the handle 60 has a first attachment portion 60a that is attached to the attachment holes 23b, 24b formed on the left side (one side in the width direction) of the bag body 1, a second attachment portion 60b that is attached to the attachment holes 23b, 24b formed on the right side (the other side in the width direction) of the bag body 1, and a main body portion 60c that extends from the first attachment portion 60a to the second attachment portion 60b. The handle 60 can be made of a flexible resin material, for example, and a resin material that is as flexible as the sheets 10-12 or harder than the sheets 10-12 can be used. The handle 60 may be made of the same material as the sheets 10-12.

[0045] Although not shown, the first attachment portion 60a includes, for example, a pin-shaped portion that is inserted into the attachment holes 23b, 24b from the front side of the bag body 1, and a retaining portion that is fixed to the tip of the pin-shaped portion and prevents the pin-shaped portion from coming out of the attachment holes 23b, 24b. The first attachment portion 60a may also be configured as a hook or the like that can be hooked onto the attachment holes 23b, 24b. In short, the first attachment portion 60a may have a structure that can be locked or engaged with the attachment holes 23b, 24b to prevent it from coming out. The second attachment portion 60b can be configured in a similar manner.

[0046] When the description is based on the assumption that the bag is not in use, the main body 60c of the handle 60 is curved in a direction away from the lower part of the bag 1. The width of the longitudinal middle part of the main body 60c may be formed wider than the longitudinal end parts. This reduces the load when the handle 60 is held by hand. The length of the handle 60 can be set arbitrarily, but it is preferable to set it so that a part of the bag 1 does not come into contact with the ground or the like when the hand holding the handle 60 is naturally lowered.

[0047] The handle 60 may be, for example, glued or welded. The portion that will become the handle 60 may be integrally formed with at least one of the top sheet 10, the back sheet 11, and the bottom sheet 12. That is, a ring-shaped portion that can be inserted with a finger can be integrally formed with at least one of the top sheet 10, the back sheet 11, and the bottom sheet 12, and this can be used as a handle. The handle 60 may also be made of, for example, a string-like member, and in this case, both ends of the string-like member may be tied to the mounting holes 23b and 24b, respectively.

[0048] When in the in-use position, the left-right center of the handle 60 and the left-right center of the bag body 1 are located on the same vertical line. Since the center of gravity of the bag body 1 when it contains liquid is at or near the left-right center, the center of the handle 60 and the center of gravity of the bag body 1 are approximately aligned in the left-right direction. This makes it difficult for the bag body 1 to deform easily.

[0049] As shown in Figure 7, a handle opening 61 may be formed in the bag 1 without attaching a separate handle 60 to the bag 1. The handle opening 61 penetrates the front bottom seal 23 and the back bottom seal 24 in the thickness direction and is long in the left-right direction. The size of the handle opening 61 is set so that at least one finger, preferably several fingers, of an adult male can fit through it.

[0050] When forming the handle opening 61, the vertical dimensions of the left-right intermediate portions of the front bottom seal portion 23 and the back bottom seal portion 24 are made long. This allows the handle opening 61 to be formed without reducing the welding strength of the front bottom seal portion 23 and the back bottom seal portion 24. Only one handle opening 61 may be formed, or two or more handle openings 61 may be formed. Furthermore, in addition to the handle opening 61, the handle 60 may be attached to the bag body 1.

[0051] (Electric spreading tool) Next, the configuration of the electric sprayer 80 shown in Figure 1 will be described. The electric sprayer 80 comprises an appliance main body 81, a pipe portion 82, and a nozzle portion 83. The appliance main body 81 is provided with a pump, an electric motor that drives the pump, a battery that supplies power to the electric motor, and other components, all of which are not shown. The appliance main body 81 is configured so that the user can hold it in one hand. The appliance main body 81 is also provided with an ON / OFF operation switch 81a. By operating the operation switch 81a, the user can activate the electric motor or stop the electric motor while it is in operation.

[0052] The pipe portion 82 is provided so as to protrude from the tip of the device body 81. The liquid discharged from the pump flows inside the pipe portion 82. The nozzle portion 83 is provided at the tip of the pipe portion 82. The liquid that has flowed inside the pipe portion 82 is discharged from the nozzle portion 83. The nozzle portion 83 may be one that sprays the liquid in a shower-like manner or in a mist-like manner.

[0053] 5, an intake port 81b communicating with the intake side of a pump is formed at the base end of tool body 81. Incidentally, electric sprayer 80 can also be called, for example, a sprayer.

[0054] (flexible hose) As shown in Figure 5, the main body of flexible hose 70 is made of, for example, a flexible tube made of resin. The length of the main body of flexible hose 70 can be set as desired, for example, to 100 cm or more. By setting the length to this extent, when using the device as described below, the spraying range can be expanded by holding bag body 1 in one hand and moving electric sprayer 80 up and down and left and right with the other hand.

[0055] The base end of the main body of flexible hose 70 is provided with a base end connecting portion 71 that connects to tubular portion 14b of bag body 1. Base end connecting portion 71 is formed to cover tubular portion 14b. A thread groove 71a that screws onto thread 14d is formed on the inner circumferential surface of base end connecting portion 71. By screwing thread 14d of tubular portion 14b into thread groove 71a of base end connecting portion 71 and tightening base end connecting portion 71, the base end of flexible hose 70 can be connected to the inside of tubular portion 14b. By loosening base end connecting portion 71, it can be removed from tubular portion 14b. In other words, outlet forming member 14 is a connecting portion for flexible hose 70, which is connected to electric sprayer 80.

[0056] The tip of the main body of flexible hose 70 is provided with tip connector 72 which is connected to suction port 81b of powered sprayer 80. Tip connector 72 is cylindrical, and is adapted to be connected to suction port 81b by fitting into said suction port 81b.

[0057] (When using liquid spray device A) Next, the use of liquid spraying device A will be described. First, as shown in Figure 5, with bag body 1 in the unused position, cap 15 is removed and then base end connection portion 71 of flexible hose 70 is connected to tubular portion 14b. Base end connection portion 71 of flexible hose 70 is also connected to suction port 81b of electric sprayer 80. Handle 60 is also attached to mounting holes 23b and 24b. This completes the preparation process.

[0058] The process then moves to the spraying step. As shown in Figure 8, after connecting flexible hose 70 to bag 1 and electric sprayer 80, the user holds handle 60 of bag 1 in one hand and tool body 81 of electric sprayer 80 in the other hand.

[0059] When holding the bag 1, because the handle 60 is attached to the lower part of the bag 1, the bag 1 is turned upside down from the unused position to the used position, with the handle 60 positioned at the upper part of the bag 1 and the outlet 14c (shown in FIG. 5) of the bag 1 positioned at the lower part of the bag 1. When the bag 1 is in the used position, the outlet 14c faces downward. If the handle opening 61 shown in FIG. 7 is formed in the bag 1, the handle opening 61 will be positioned at the upper part of the bag 1.

[0060] When the user operates operation switch 81a to activate the pump, the liquid inside bag 1 is sucked through flexible hose 70 and into tool body 81 from suction port 81b. The liquid sucked into tool body 81 flows through tube portion 82 and is then discharged from nozzle portion 83. Liquid can be sprayed continuously while the electric motor of electric sprayer 80 is operating.

[0061] If the liquid is a herbicide, pesticide, or pesticide, it can be sprayed, for example, on home vegetable gardens, hedges, fruit trees, high-altitude garden trees, etc. By using the electric sprayer 80, it is possible to easily spray from low to high places. The liquid sprayer A can also be used to control weeds and prevent pests.

[0062] During spraying of the liquid, the outlet 14c of the bag body 1 faces downward, which allows the flexible hose 70 connected to the outlet 14c to hang down smoothly. This makes the flexible hose 70 between the electric sprayer 80 and the outlet 14c less likely to bend, allowing for smooth spraying. The electric sprayer 80 can be used facing downward or upward. Because the flexible hose 70 is sufficiently long, in either case, there is no need to change the height of the bag body 1; simply keep the hand holding it down naturally. Note that, although the height of the bag body 1 may be changed in some cases, the tool body 81 is generally positioned higher than the bag body 1.

[0063] When the liquid is sprayed, the liquid B contained in the bag 1 flows out from the outlet 14c at the bottom of the bag 1, eliminating the need for the dip tube provided in the conventional example. As a result, even if the liquid B inside the bag 1 decreases and the bag 1 is crushed by negative pressure, the problem of the dip tube breaking does not occur. Therefore, there is no problem with residual liquid, and the user can spray all of the liquid B in the bag 1 without performing any special operations.

[0064] When the liquid B inside the bag 1 runs out, simply prepare a new bag 1 and replace it. The bag 1 that has run out of liquid B will need to be discarded, but since there is no dip tube, it does not get in the way when discarding the bag 1, and there is no need to insert or remove the dip tube, making it easy for the user to handle. In addition, the liquid will not get on your hands.

[0065] (liquid sprayer package) Because liquid spraying device A is composed of bag body 1, flexible hose 70, handle 60, and electric sprayer 80, bag body 1, flexible hose 70, handle 60, and electric sprayer 80 may be housed in a single package and displayed in a store. The package may be, for example, a bag or a case. Alternatively, the flexible hose 70, handle 60, and electric sprayer 80, excluding bag body 1, may be housed in a single package and displayed in a store. In this case, bag body 1 can be purchased separately and connected to flexible hose 70. In other words, a set consisting of bag body 1, flexible hose 70, handle 60, and electric sprayer 80, or a set consisting of flexible hose 70, handle 60, and electric sprayer 80, can be configured.

[0066] (Effects of the embodiment) As described above, liquid spraying device A according to this embodiment comprises bag 1 having outlet 14c, electric sprayer 80 capable of continuously spraying liquid, and flexible hose 70 connecting outlet 14c of bag 1 with inlet 80b of electric sprayer 80, so that when electric sprayer 80 sprays liquid, outlet 14c is positioned at the bottom of bag 1. This allows for spraying without leaving any liquid behind while reducing the amount of plastic used without using a rigid plastic container as a spraying container, and also makes it easier for users to handle since a dip tube is no longer necessary.

[0067] The above-described embodiments are merely examples in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention. [Industrial Applicability]
