Description

[Technical Field]

[0001] The present disclosure relates to a shower nozzle for spraying liquid and a spraying container equipped with the shower nozzle. [Background technology]

[0002] For example, Patent Document 1 discloses a shower nozzle that has a shower hole for spraying a liquid in a shower-like manner and a cap connected by a hinge part. This type of shower nozzle is attached to a spray container for herbicides or the like, and when spraying the liquid in a shower-like manner, the elastic force of the hinge part holds the cap in an open position.

[0003] In shower nozzles with caps like this, the hinge is typically positioned on the opposite side of the target surface (i.e., above the shower nozzle body during spraying) and is positioned so that an elastic force acts in the direction of the cap opening upward. For example, Figure 4 of Patent Document 2 discloses a configuration in which the hinge is positioned on the opposite side of the target surface (ground).

[0004] On the other hand, in recent years, in order to reduce the amount of plastic used, the use of pouches made of thin resin sheets as disclosed in Patent Document 3 has been considered in place of plastic containers such as those in Patent Document 2. Figure 13 of Patent Document 3 discloses a configuration in which an adapter with multiple through-holes is attached to the spout of the pouch. In Patent Document 3, it is possible to discharge liquid through this adapter.

[0005] Furthermore, during manufacturing, when attaching a spout to a pouch, as disclosed in Patent Document 4, for example, it is common to correct the orientation of the spout around its axis, and then clamp the bag opening from both sides to weld-seal the spout to the bag opening, thereby attaching the spout so that its orientation around its axis is constant relative to the pouch. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Design Registration No. 1745000 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-18517 [Patent Document 3] Patent No. 6712158 [Patent Document 4] Patent No. 4530882 Summary of the Invention [Problem to be solved by the invention]

[0007] However, when the cap is attached to the shower nozzle body via a hinge, as in Patent Document 2, if the hinge is positioned away from the ground during spraying, gravity acts on the cap in a closing direction when the container is tilted for spraying. This can cause the cap to unintentionally move in the closing direction during spraying. If the cap moves in the closing direction during spraying, liquid flowing out of the shower hole will hit the cap, preventing spraying from continuing.

[0008] Furthermore, since the spout of the pouch in Patent Document 3 cannot be used for shower-like spraying, it is conceivable to attach the shower nozzle in Patent Document 1 to the spout of the pouch in Patent Document 3 with a screw to enable shower-like spraying, but this would pose another problem.

[0009] That is, the spout of the pouch is positioned relative to the pouch body around its axis. However, when correcting the orientation of the spout around its axis as in Patent Document 4, the spout can take either of two positions: one in which the reference portion of the spout is located above the pouch, and one in which the spout is rotated 180 degrees around the axis from that position. The device in Patent Document 4 cannot control which position the spout will be welded to the pouch in, so pouches with spouts welded in one position and pouches with spouts welded in the other position will be mixed together.

[0010] When attaching a shower nozzle to a spout with screws, the threads are formed on the spout so that the cap opens upwards when the shower nozzle is tightened, but if the spout rotates 180 degrees around its axis as in Patent Document 4, the tightened shower nozzle also rotates 180 degrees around its axis. As a result, when spraying, the cap opens diagonally downward, and liquid flowing out of the shower hole hits the cap, preventing shower-like spraying.

[0011] The present disclosure has been made in consideration of such points, and its purpose is to prevent the shower nozzle cap from closing unintentionally during spraying, and to enable shower-like spraying even if the spout is misaligned 180 degrees around its axis when the shower nozzle is attached to the spout with a screw. [Means for solving the problem]

[0012] To achieve the above object, one aspect of the present disclosure is a shower nozzle that is attached to a container that contains a liquid. The shower nozzle includes a shower nozzle body having a shower hole forming section with shower holes for the liquid to flow out, the shower hole forming section facing downward when the liquid is sprayed, a cap that covers the shower hole forming section, and a hinge that supports the cap so that it can be opened and closed around an axis that extends in a predetermined direction relative to the shower nozzle body. The axis of the hinge is oriented so that the cap opens sideways when the shower hole forming section is facing downward when spraying.

[0013] With this configuration, after the cap is rotated open around the hinge axis, tilting the container so that the shower hole forming portion faces downward causes the liquid contained in the container to be sprayed from the shower hole. Because the cap is positioned to open sideways during spraying, the closing force due to gravity acting on the cap is smaller than when the cap is open facing upward. This prevents the cap from accidentally closing during spraying.

[0014] Furthermore, when the shower nozzle is attached to the spout of the pouch with a screw, even if the spout rotates 180 degrees around its axis as described above, the cap opens sideways, so the only difference is whether the opening direction is to the right or left. Therefore, the cap does not open diagonally downward, so the liquid flowing out of the shower hole does not hit the cap.

[0015] The cap may be integrally molded on the side of the shower hole forming portion via the hinge portion. For example, the cap, the shower hole forming portion, and the hinge portion may be integrally molded from resin. In this case, the hinge portion may be configured as a thin hinge portion that is thinner than the cap and the shower hole forming portion. That is, in the case of a thin hinge portion, the cap must be held in the open position by the elasticity of the resin. However, this elasticity is not very strong, so if the cap opens upward as in conventional examples, it may be prone to closing due to gravity. In contrast, by designing the cap to open sideways as in the present embodiment, the cap can be maintained in the open position even with a small force in the opening direction from the thin hinge portion.

[0016] The pivot angle of the cap by the hinge portion can be set to 180° or more. By pivoting the cap open in this manner, liquid flowing out from the shower hole can be prevented from hitting the cap.

[0017] The shower hole forming portion may have an outer periphery surrounding the plurality of shower holes, in which case the hinge portion may be integrally formed with the outer periphery.

[0018] Another aspect of the present disclosure may be a spray container. The spray container includes a container for containing a liquid and a shower nozzle attached to the container. The shower nozzle includes a hinge that supports the cap so that it can be opened and closed around an axis extending in a predetermined direction relative to the shower nozzle body. The hinge axis is positioned so that the cap opens sideways when the shower hole forming portion faces downward during spraying.

[0019] The container may also be a pouch made of a resin sheet. In this case, a spout separate from the resin sheet can be attached to the pouch, and the shower nozzle can be attached to the spout with screws. That is, since the spout is a separate component from the resin sheet that forms the pouch, it may be attached rotated 180 degrees around its axis relative to the pouch. However, in this embodiment, as described above, the cap opens sideways, so the liquid flowing out of the shower hole does not hit the cap. [Effects of the Invention]

[0020] As explained above, by positioning the cap so that it opens sideways when spraying, it is possible to prevent it from closing unintentionally, and when the shower nozzle is attached to the spout with screws, even if the spout is misaligned 180 degrees around the axis, the cap will not get in the way and the liquid can be sprayed in a shower-like manner.

[0022] 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.

[0023] Figure 1 is a perspective view of a spraying container 1 according to an embodiment of the present invention. The spraying container 1 comprises a container 2 for containing a liquid, a spout 3, and a shower nozzle 4. The shower nozzle 4 comprises a shower nozzle body 40, a cap 41, and a hinge 42 that supports the cap 41 so that it can be opened and closed relative to the shower nozzle body 40. Figure 2 shows the cap 41 in an open position.

[0024] In the description of this embodiment, the front-to-rear direction, left-to-right direction, and up-to-down direction of the spraying container 1 are defined as shown in each figure. That is, the side that would be up when the spraying container 1 is stored, for example, on a stand (not shown), is defined as the top, and the side that would be down is defined as the bottom. As shown in FIG. 4, when spraying a liquid, the spraying container 1 is in an orientation that is approximately upside down so that the top faces down. Furthermore, the side on which the shower nozzle 4 is attached is defined as the front, and the side opposite the side on which the shower nozzle 4 is attached is defined as the rear. The front side can also be called the front side, and the rear side can also be called the rear side. Furthermore, the side that is left when the spraying container 1 is viewed from the rear toward the front is defined as the left, and the side that is right when the spraying container 1 is viewed from the rear toward the front is defined as the right. The width direction of the spraying container 1 is the left-to-right direction. These directional definitions are provided for convenience in describing the embodiment and do not limit the orientation during actual storage or use.

[0025] The storage section 2 can store, for example, herbicides, liquid fertilizers, detergents, disinfectants, bactericides, pest repellents, insecticides, liquid wax, water, etc., and may store any one of these, or any two or more of them in combination. The internal volume of the storage section 2 is not particularly limited, but can be, for example, 100 ml or more, or 1000 ml or more, with the upper limit being, for example, 6000 ml or less. The size of the storage section 2 is also not particularly limited, and can be any size to match the internal volume. The shape of the storage section 2 is also not particularly limited, and may be long in the vertical direction, long in the front-to-back direction, or wide in the width direction.

[0026] 3, the storage unit 2 is a pouch made up of a plurality of resin sheets 21, 22, and 23. The resin sheets 21, 22, and 23 are flexible, and therefore the storage unit 2 is easily deformed. By making the storage unit 2 a pouch made up of a plurality of resin sheets 21, 22, and 23, the amount of plastic used can be reduced compared to when a container made of hard resin is used.

[0027] The resin sheets 21, 22, and 23 may be, for example, laminate sheets in which a plurality of resin films are stacked and integrated, or may be sheets composed of a single-layer resin film. The resin sheets 21, 22, and 23 may or may not be translucent. The resin sheets 21, 22, and 23 have heat sealability that allows them to be thermally welded to each other. The resin sheets 21, 22, and 23 may be provided with a metal layer.

[0028] The resin sheet 21 is a right-side sheet that forms the right portion of the storage section 2. The resin sheet 22 is a left-side sheet that forms the left portion of the storage section 2. The resin sheet 23 is a bottom sheet that forms the bottom of the storage section 2. The upper edge, front edge, and rear edge of the right-side sheet 21 are welded to the upper edge, front edge, and rear edge of the left-side sheet 22, respectively. Furthermore, the right side of the rear edge, right edge, and right side of the front edge of the bottom sheet 23 are welded to the lower side of the rear edge, lower edge, and lower side of the front edge of the right-side sheet 21, respectively. Furthermore, the left side of the rear edge, left edge, and left side of the front edge of the bottom sheet 23 are welded to the lower side of the rear edge, lower edge, and lower side of the front edge of the left-side sheet 22, respectively. Each welded portion is sealed to prevent liquid leakage.

[0029] The rear portions of the right-side sheet 21 and the left-side sheet 22 have openings 21a, 22a for forming handles. The openings 21a, 22a are located outside the space for storing the liquid and have a shape that is elongated in the vertical direction. The shape of the handle is not limited to that shown in the figure and may be any shape. The position of the handle is not limited to that shown in the figure and may be provided anywhere in the storage section 2. A separate handle may also be attached to the storage section 2. Multiple handles may also be provided. For example, a first handle may be provided on the rear side of the storage section 2 and a second handle may be provided on the upper side of the storage section 2. When the storage section 2 has a large capacity, it is preferable to provide multiple handles. When multiple handles are provided, a carrying handle for carrying the spraying container 1 may be provided on the upper side of the storage section 2, and a spraying handle for holding the spraying container during spraying may be provided on the rear side of the storage section 2.

[0030] A spout 3, which is a separate part from the resin sheets 21, 22, and 23, is attached to the storage section 2. The spout 3 is made of, for example, a hard resin material. As shown in FIG. 3, the spout 3 is tubular with both ends open, and in FIG. 1, the axis of the spout 3 is indicated by a dashed dotted line A. The axis A of the spout 3 extends generally in the vertical direction and is inclined so that the upper part is positioned further forward.

[0031] Because spout 3 is cylindrical, a flow path R1 (shown in Figure 3) is formed inside it, extending in the direction of axis A. The lower end of flow path R1 is the upstream end, and is connected to the interior of container 2. The upper end of flow path R1 is the downstream end, and is connected to the interior of shower nozzle 4.

[0032] The base 30 of the spout 3 has a hexagonal cylindrical shape centered on the axis A. The front portion of the upper edge of the right sheet 21 is welded to the right portion of the outer periphery of the base 30, and the front portion of the upper edge of the left sheet 22 is welded to the left portion of the outer periphery of the base 30. This allows the base 30 of the spout 3 to be attached to the right sheet 21 and the left sheet 22, preventing liquid from leaking between the base 30 and the right sheet 21 or left sheet 22.

[0033] The portion of the spout 3 closer to the tip than the base 30 is the connecting tube 31 to which the shower nozzle 4 is connected, and the tip face of the connecting tube 31 is open. The connecting tube 31 is cylindrical and has an outer diameter smaller than that of the base 30. The outer surface of the connecting tube 31 is formed with a screw thread 31a.

[0034] The shower nozzle 4 is attached to the connecting tube 31 of the spout 3 with screws. Figure 5 shows the cap 41 in the open position. As shown in Figure 6, the shower nozzle 4 is composed of two parts: a connecting member 4A that connects to the spout 3, and a nozzle member 4B. The connecting member 4A and the nozzle member 4B are each made of, for example, resin. For example, the connecting member 4A can be integrally molded from resin, and the nozzle member 4B can also be integrally molded from resin. The shower nozzle 4 can then be completed by assembling the nozzle member 4B to the connecting member 4A. The shower nozzle 4 does not have to be composed of two parts; it could be a single integrally molded part, or it could be three or more parts. The connecting member 4A and the nozzle member 4B can be made of the same resin, or different resins.

[0035] The connecting member 4A is cylindrical overall, with a base-end tubular portion 43 on the side connected to the spout 3. The base-end tubular portion 43 is formed to cover the connecting tubular portion 31 of the spout 3. A thread groove 43a is formed on the inner peripheral surface of the base-end tubular portion 43 to thread onto the thread 31a formed on the outer peripheral surface of the connecting tubular portion 31. By threading the thread groove 43a of the base-end tubular portion 43 onto the thread 31a of the connecting tubular portion 31 and tightening it, liquid does not leak from between the spout 3 and the connecting member 4A. A rubber packing (not shown) may be provided between the spout 3 and the connecting member 4A.

[0036] The portion of the connecting member 4A closer to the tip than the base-end-side tubular portion 43 is a tapered expanded diameter portion 44 that increases in diameter as it approaches the tip. The tip of the expanded diameter portion 44 is provided with an attachment portion 44a to which the nozzle member 4B is attached. The attachment portion 44a has an annular shape. A groove portion 44b is provided continuously in the circumferential direction on the outer peripheral surface of the attachment portion 44a.

[0037] Figure 7 shows a shower nozzle 4 according to a first variation of the embodiment. As in this first variation, the proximal tubular portion 43 of the connecting member 4A can be made smaller in diameter than that shown in Figure 6. For example, if the capacity of the housing 2 is small, the outer diameter of the spout 3 will be small, so the proximal tubular portion 43 can be made smaller accordingly. The nozzle member 4B in the example shown in Figure 6 and the nozzle member 4B in the example shown in Figure 7 are the same. Details of the nozzle member 4B are described below.

[0038] The nozzle member 4B has a shower hole forming portion 46. The peripheral edge of the shower hole forming portion 46 forms a fitting portion 45 that fits onto the outside of the mounting portion 44a. The fitting portion 45 is cylindrical and extends along the outer circumferential surface of the mounting portion 44a. The inner circumferential surface of the fitting portion 45 is provided with ridges 45a that fit into the recesses 44b and are continuous in the circumferential direction.

[0039] A plurality of shower holes 46a for causing the liquid to flow out in a shower-like manner are formed in the inner portion of the fitting portion 45 of the shower-hole forming portion 46. In other words, the fitting portion 45 is an outer peripheral portion that surrounds the plurality of shower holes 46a. The portion of the shower-hole forming portion 46 surrounded by the fitting portion 45 is disk-shaped, but this shape is not particularly limited. The shower-hole forming portion 46 is gently curved so that its radial center is located downstream in the liquid flow direction compared to the periphery.

[0040] In this embodiment, a plurality of shower holes 46a are formed so as to penetrate the shower hole forming portion 46 in the thickness direction from the center to the periphery of the shower hole forming portion 46. The plurality of shower holes 46a are arranged at intervals from one another in the circumferential and radial directions of the shower hole forming portion 46. The intervals between the plurality of shower holes 46a may be equal or may be uneven. The cross section of each shower hole 46a is circular. The diameter, number, and intervals of the shower holes 46a can be set as desired depending on the flow rate, viscosity, etc. of the liquid to be sprayed.

[0041] The fitting portion 45 protrudes downstream in the liquid flow direction from the periphery of the shower hole forming portion 46, and this protruding portion forms a peripheral wall portion 45b. Furthermore, a protruding portion 46b that fits into the inside of the mounting portion 44a of the connecting member 4A is formed on the inner surface (the surface on the upstream side in the liquid flow direction) of the shower hole forming portion 46. Therefore, the mounting portion 44a is inserted between the protruding portion 46b and the fitting portion 45.

[0042] In this embodiment, the shower nozzle body 40 is made up of the connecting member 4A, the fitting 45, and the shower hole forming portion 46. As shown in Figure 2, when liquid is not being sprayed from the spraying container 1, the shower nozzle body 40 is positioned so that the shower hole forming portion 46 faces upward. On the other hand, as shown in Figure 4, when liquid is being sprayed from the spraying container 1, the shower nozzle body 40 is positioned so that the shower hole forming portion 46 faces downward. In this case, the shower hole forming portion 46 may face diagonally downward or straight down.

[0043] The cap 41 is for covering the shower-hole forming portion 46, and has a circular outer shape that is larger than the fitting portion 45. Recesses 41a, into which the peripheral wall portion 45b of the fitting portion 45 fits, are formed continuously in the circumferential direction around the periphery of the cap 41. When the cap 41 is closed, the peripheral wall portion 45b of the fitting portion 45 fits into the recesses 41a, thereby maintaining the cap 41 in a closed state and sealing the gap between the peripheral edge of the cap 41 and the peripheral edge of the shower-hole forming portion 46, thereby preventing liquid from leaking between the peripheral edges of the cap 41 and the shower-hole forming portion 46. Furthermore, the portion of the cap 41 inside the portion where the recesses 41a are formed is curved to correspond to the curved shape of the shower-hole forming portion 46.

[0044] The cap 41 is integrally molded via a hinge 42 to the side of the fitting 45 of the shower hole forming portion 46. Specifically, the cap 41, shower hole forming portion 46, and hinge 42 are integrally molded from resin. The hinge 42 is a thin-walled hinge that is thinner than the cap 41 and shower hole forming portion 46, and supports the cap 41 so that it can be opened and closed around an axis extending in a specific direction relative to the shower nozzle body 40. The pivot angle of the cap 41 via the hinge 42 is 180° or more, allowing the cap 41 to be opened widely. However, the pivot angle of the cap 41 via the hinge 42 may be less than 180°.

[0045] The opening direction of the cap 41 can be set by the orientation of the axis of the hinge portion 42. In this embodiment, the axis of the hinge portion 42 is positioned so that the cap 41 opens sideways. That is, the axis of the hinge portion 42 is positioned on the right side of the shower hole forming portion 46 and is inclined overall so that the hinge portion 42 is positioned further back as it goes up. Therefore, in a plan view of the spraying container 1, the axis of the hinge portion 42 extends in the front-to-rear direction. By opening the cap 41 to the right about the axis extending in the front-to-rear direction in a plan view, the open state of the cap 41 is positioned to the right of the shower hole forming portion 46. The open state of the cap 41 is maintained by the elastic force of the hinge portion 42, but this holding force is not set to be very strong, allowing the user to open and close the cap 41 with little force.

[0046] As shown in Figure 4, when spraying, the spraying container 1 is turned upside down so that the shower hole forming portion 46 faces downward. When the shower hole forming portion 46 faces downward during spraying, the cap 41 is positioned sideways, i.e., open to the right. In other words, the axis of the hinge portion 42 is oriented so that when the shower hole forming portion 46 faces downward during spraying, the cap 41 opens to the right. The axis of the hinge portion 42 is oriented so that the cap 41 opens to the right when the shower nozzle 4 is fully attached to the connecting tube portion 31 of the spout 3 with the screws.

[0047] In the example shown in Figure 2, hinge part 42 is provided on the right side of fitting part 45 of shower hole forming part 46, but this is not limiting, and hinge part 42 may be provided on the left side of fitting part 45 of shower hole forming part 46, as in Modified Example 2 shown in Figures 8 to 10. In this Modified Example 2, the direction of the axis of hinge part 42 is set so that cap 41 opens to the left when shower hole forming part 46 is oriented so that it faces downward during spraying.

[0048] That is, when welding the spout 3 to the storage section 2, a method such as that disclosed in Patent Document 4 can be used. The method disclosed in Patent Document 4 corrects the orientation of the spout 3 around its axis, and the spout 3 can take both a first position in which the reference portion of the spout 3 is located, for example, above the storage section 2, and a second position in which the spout 3 is rotated 180° around its axis from the first position. If the thread 31a and the thread groove 43a are formed so that the hinge portion 42 is located on the right as shown in FIG. 1 in the first position, then in the second position, the hinge portion 42 will be rotated 180° and located on the left as shown in FIG.

[0049] When the hinge 42 is located on the right or left side, the user will open the cap 41 sideways as described above, which is an action that is completely different from the action of opening it upward as in the case where the hinge is located on the upper side. However, when eight men and women aged from their 20s to 60s were asked to operate the cap 41 to open it sideways, six of them said that they did not feel uncomfortable, so the user can open the cap 41 sideways without any discomfort.

[0050] (Effects of the embodiment) As described above, in this embodiment, the storage section 2 is configured as a pouch, which reduces the amount of plastic used and the environmental impact. When storing or transporting the spraying container 1 containing a liquid, the shower nozzle 4 can be removed from the spout 3, and the spout 3 can be closed with a cap (not shown). This allows the spraying container 1 equipped with the shower nozzle 4 to be made compact. When storing or transporting the spraying container 1, the shower nozzle 4 can simply be attached to the storage section 2.

[0051] When spraying liquid from the spraying container 1, the shower nozzle 4 is attached to the spout 3. At this time, the connecting tube 31 of the spout 3 is inserted into the base end tube 43 of the shower nozzle 4, and the shower nozzle 4 is rotated to thread the thread 31a into the thread groove 43a. When the thread 31a is fully threaded into the thread groove 43a, the shower nozzle 4 is attached to the spout 3, and the hinge part 42 is positioned either on the right side as shown in FIG. 1 or on the left side as shown in FIG. 8.

[0052] In the example shown in FIG. 1, the cap 41 is opened by rotating it clockwise around the axis of the hinge portion 42. At this time, by holding the spout 3 with one hand, the position of the cap 41 can be fixed, and the cap 41 can be easily opened with the other hand. After opening the cap 41, tilting the storage portion 2 so that the shower hole forming portion 46 faces downward as shown in FIG. 4 causes the liquid stored in the storage portion 2 to be sprayed from the shower holes 46a. During this spraying, the cap 41 is positioned so that it opens sideways, so the closing force due to gravity acting on the cap 41 is smaller than when the cap 41 is open facing upward. This prevents the cap 41 from closing unintentionally during spraying.

[0053] In the case shown in Figure 8, the cap 41 is rotated to the left around the axis of the hinge portion 42 to open it, and then the liquid is sprayed as shown in Figure 10.In this case, too, the closing force due to gravity acting on the cap 41 is smaller than when the cap 41 is open facing upward, so the cap 41 is prevented from closing unintentionally during spraying.

[0054] When shower nozzle 4 is attached to spout 3 of container 2 with a screw, even if spout 3 rotates 180 degrees around its axis as described above, cap 41 opens sideways, so the only difference is whether it opens to the right or left. Therefore, cap 41 does not open diagonally downward, so cap 41 does not get in the way when spraying, and liquid flowing out of shower hole 46a will not hit cap 41.

[0055] After using the shower nozzle 4, if liquid remains in the container 2, the cap 41 can be rotated in the closing direction to close the shower holes 46a. To spray again, simply open the cap 41 as described above.

[0056] The above-described embodiment is merely illustrative 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. The storage unit 2 may be, for example, a resin bottle other than a pouch. [Industrial Applicability]

[0057] As described above, the shower nozzle and shower nozzle spray container according to the present disclosure can be used to spray various liquids. [Explanation of symbols]
