Description

Technical Field

[0001] The present invention relates to an aerosol actuator that is attached to an aerosol container and can operate a stem to extract the contents, and particularly to an aerosol actuator that can be operated with one hand.

Background Art

[0002] Conventionally, as an aerosol actuator that is attached to an aerosol container and can operate a stem to extract the contents, the aerosol device described in Patent Document 1 is known.

[0003] The aerosol actuator (aerosol device) known from this Patent Document 1 has a main body part (over cap 24) attached to an aerosol container (1), a nozzle (upper body 20) fitted to a stem (12), and a push button (18) connected to the nozzle (upper body 20). The main body part (over cap 24) is provided with a discharge port (spray passage 33) that opens to the side and a rotatably attached operation part (pressing body 26). The nozzle (upper body 20) is provided with a flow path through which the contents discharged from the stem (12) can pass. The flow path of the nozzle (upper body 20) and the discharge port (spray passage 33) of the main body part (over cap 24) are communicated by a spray pipe (21). The aerosol device known from this Patent Document 1 operates the stem (12) by rotating the operation part (pressing body 26) and pressing the push button (18) in the upright state to extract the contents in the aerosol container (1), and discharges the contents from the discharge port (spray passage 33) through the flow path and the spray pipe (21). By pressing the operation part (pressing body 26) with the thumb while placing the index finger under the discharge port (spray passage 33), the contents discharged from the discharge port (spray passage 33) can be directly applied with one hand onto the palm of the hand operating the operation part (pressing body 26).

[0004] Furthermore, an aerosol product (discharge container) is known from Patent Document 2, which is composed of an aerosol actuator (head member 20) having a main body (head body 21) that fits onto a stem (16) and a lid (24) that covers the main body (head body 21), the main body (head body 21) having a top plate (base portion 27) and a discharge cylinder (flow hole 26) that connects the stem (16) and a discharge port (discharge hole 11) provided on the discharge surface (29) on the upper surface of the top plate (base portion 27), and the lid (24) is provided with a core (25) that can be inserted from the discharge port (discharge hole 11) into the discharge cylinder (flow hole 26). The aerosol product (dispensing container) equipped with the aerosol actuator (head member 20) described in Patent Document 2 allows the contents to be dispensed from the aerosol container (dispensing container body 10) by pushing the aerosol actuator (head member 20) into the main body (head body 21) with the lid (24) placed over it, activating the stem (16). After the contents are dispensed from the aerosol container (dispensing container body 10) onto the dispensing surface (29) through the dispensing port (dispensing hole 11), the lid (24) can be removed and the contents can be scooped up by hand. This allows for one-handed operation regardless of the circumferential orientation of the upright aerosol product (dispensing container). Furthermore, by discharging the contents while the core (25) is inserted into the discharge cylinder (flow hole 26), it is prevented that the contents will be unevenly distributed and discharged to a specific location on the discharge surface (29).

[0005] [Patent Document 1] Japanese Patent Application Publication No. 8-281160 [Patent Document 2] Japanese Patent Publication No. 2016-33032 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, the aerosol actuators described in the above-mentioned patent documents still had room for improvement.

[0007] In other words, the aerosol actuator described in Patent Document 1, etc., has a discharge port that opens to the side, so in order to dispense the contents with one hand, it is necessary to use it in a way that aligns the direction of the discharge port with the direction of the operating hand, which could make the work cumbersome. Furthermore, because the contents are dispensed by gripping the operating part and nozzle between the thumb and index finger, there was a risk of the aerosol container tipping over, or of gripping it too tightly and causing the fingers to slip, or deforming the nozzle or operating part. Furthermore, when using the aerosol container with one hand, the contents could stick to the fingers holding the nozzle after being dispensed, making it slippery and increasing the risk of accidentally dropping the container.

[0008] Furthermore, in the aerosol actuator described in Patent Document 2, etc., the aerosol actuator, including the discharge surface, is supported by a stem fitting portion that fits into the stem. Therefore, when the stem is operated, the entire aerosol actuator moves up and down. Depending on how the aerosol actuator is pushed in, the discharge surface may tilt diagonally as it moves up and down, and there is a risk that the discharged contents will be unevenly distributed and discharged to a specific part of the discharge surface. Furthermore, if excessive force is applied to the aerosol actuator from a position away from its center, the stem may tilt, potentially preventing it from being fully pushed in, bending or breaking, or causing the aerosol container to tilt and tip over.

[0009] The present invention aims to solve these problems by providing an aerosol actuator with a simple configuration that can be operated with one hand without tipping over or slipping the aerosol container, and that reliably operates the stem to dispense the contents without placing a large load on the stem. [Means for solving the problem]

[0010] The aerosol actuator of the present invention comprises a main body portion fixed to an aerosol container via a fixing portion, a nozzle fitted to a stem, and an operating portion for operating the nozzle, wherein the main body portion comprises a top plate portion provided above the fixing portion and a main body connecting portion hanging down from the top plate portion, and the nozzle comprises a stem fitting portion fitted to the stem, a cylindrical discharge tube extending upward from the stem fitting portion, a discharge port provided at the upper part of the discharge tube, and an operating contact portion provided on the outer circumferential surface of the discharge tube. The top plate portion is provided with an insertion hole through which the discharge port is inserted. The operating section has an operating contact section that contacts the operated contact section from the side to constitute a nozzle operating mechanism, the main body connection section has a guide section that supports the operating section and allows it to move forward and backward, and the discharge port is configured to discharge contents to the upper surface of the top plate when the nozzle is operated by the nozzle operating mechanism. The nozzle operating mechanism has a plurality of operating parts provided circumferentially around the central axis of the nozzle, and each of the plurality of operating parts is configured to independently bias the nozzle in the direction of operation. This solves the aforementioned problem.

[0011] The aerosol actuator according to claim 1 has a main body with a top plate that is fixed to the aerosol container. Therefore, even when the stem is operated, the top plate does not move up and down or tilt significantly, preventing the dispensed contents from being concentrated on a specific part of the top plate or sliding off. Furthermore, since the operating part has an operating contact part that contacts the contacted part from the side to form a nozzle operating mechanism, the user can activate the nozzle operating mechanism by applying force in the direction of gripping the aerosol product and pushing the operating part sideways, thereby pushing down the stem and dispensing the contents. This allows the user to firmly grasp the aerosol product with one hand and dispense the contents. Furthermore, because the control panel is located on the side, even users with long fingernails can easily operate the control panel without getting their nails caught. Furthermore, since multiple nozzle operating mechanisms are provided circumferentially around the central axis of the nozzle, for example, if two nozzle operating mechanisms are provided facing each other around the central axis of the nozzle, when operating the control unit from the front or back of the aerosol product, the nozzle operating mechanism can be operated without changing the orientation of the aerosol product, regardless of whether the product is facing forward or backward from the user's perspective. When operating the control unit from the left or right of the aerosol product, the nozzle operating mechanism can be operated with one hand, either with the right or left hand, without changing the orientation of the aerosol product. Furthermore, by pressing multiple operating parts simultaneously, the force required to activate the nozzle mechanism can be distributed, allowing the stem to be pushed down with less force to dispense the contents.

[0012] Claim 2According to the configuration described above, at least one of the operated contact portion and the operating contact portion is an operating inclined surface composed of an inclined surface. Therefore, by bringing the operating contact portion into contact with the operated contact portion from the side and gradually pushing the operating portion, the nozzle is pushed downward along the inclination of the operating inclined surface, and the stem fitted to the nozzle is activated to dispense the contents.

[0013] Claim 3 According to the configuration described, since the multiple operating inclined surfaces are configured with different inclination angles for each of the multiple operating parts, the amount of pressure applied to the stem by the nozzle operating mechanism can be adjusted by pressing the operating part, thereby adjusting the amount and force of the contents discharged. Claim 4 According to the configuration described above, since the discharge port is located above the top plate, for example, when the contents are discharged in a foamy state, the foamy contents can remain attached to the tip of the discharge port above the top plate. This allows the foamy contents to be scooped up from below with a finger or the like, thereby reducing the amount of contents remaining on the top plate after use.

[0014] Claim 5 According to the configuration described above, the top plate is provided with a nozzle cover that covers the insertion hole from above, and the nozzle cover is provided with a communication hole that connects the inside and outside of the nozzle cover. This protects the nozzle and prevents the contents from being accidentally dispensed if fingers or other objects come into direct contact with the nozzle. Furthermore, by adjusting the shape and position of the communication holes, it is possible to control the discharge position and discharge form of the contents to a desired state. Claim 6 According to the configuration described above, the main body further has a skirt wall that hangs down from the periphery of the top plate, which prevents contents that have dripped from the periphery of the top plate from entering the inside of the aerosol actuator, and the skirt wall can be easily cleaned by wiping it.

[0015] Claim 7According to the configuration described, since the upper surface of the top plate portion is composed of an inclined surface that slopes downward from the periphery of the insertion hole toward the outer side in the radial direction, no concave portion for accumulating the content is formed on the upper surface of the top plate portion. By scooping up the discharged content from the outer peripheral edge of the top plate portion toward the center with a finger or the like, the amount of content remaining on the top plate portion after use can be suppressed. Claim 8 According to the configuration described, since the upper surface of the top plate portion is formed in a dome shape with the periphery of the insertion hole at the uppermost part, no concave portion for accumulating the content is formed on the upper surface of the top plate portion. By scooping up the discharged content from the outer peripheral edge of the top plate portion toward the center with a finger or the like, the amount of content remaining on the top plate portion after use can be suppressed. In addition, since the inclination of the peripheral portion of the insertion hole becomes gentle, the content is unlikely to slide off the top plate portion, and the discharged content can be reliably scooped up with a finger or the like.

[0016] Claim 9 According to the configuration described, a protruding portion that protrudes outward in the radial direction and extends in the vertical direction is provided on the outer peripheral surface of the nozzle, and an operating guide for guiding the protruding portion in the vertical direction is provided on the main body portion. Therefore, even when the nozzle receives a lateral force from the operating portion when the operating portion is pushed in from the side to operate the nozzle operating mechanism, the protruding portion is guided by the operating guide, and the nozzle can move only in the vertical direction without moving greatly in the lateral direction, preventing the position of the discharge port from shifting and interfering with the periphery of the insertion hole.

[Modes for carrying out the invention]

[0018] Below, an aerosol actuator 100 and an aerosol product P equipped with the aerosol actuator 100 according to one embodiment of the present invention will be described with reference to the drawings.

[0019] An aerosol actuator 100 according to one embodiment of the present invention, as shown in Figures 1 to 9, has a main body 110 fixed to an aerosol container C, a nozzle 124 fitted to a stem S, and an operating part 130.

[0020] The main body 110 has a fixing part 115 fitted to the outside of the valve unit ∨ of the aerosol container C, a top plate portion 111 formed in the shape of a flat plate, a main body connecting part 114 hanging down from the top plate portion 111 and connecting to the fixing part 115, a skirt wall 117 hanging down from the outer peripheral edge of the top plate portion 111, an insertion hole 112 provided in the center of the top plate portion 111, and an annular projection 113 formed to protrude upward from the top plate portion 111 from near the peripheral edge of the insertion hole 112. The annular projection 113 is covered by a dome-shaped nozzle cover 120, and the nozzle cover 120 is provided with multiple communication holes 121 that connect the inside and outside of the nozzle cover 120.

[0021] On the inner circumferential surface side of the main body connection portion 114, three operating guides 116 are provided, evenly spaced in the circumferential direction around the insertion hole 112. Each operating guide 116 is formed by a pair of guide wall portions 116b and is shaped like a slit that opens towards the insertion hole 112 and downwards. Furthermore, a fall prevention projection 116a is formed on the lower part of the operating guide 116, which protrudes radially inward. The skirt wall 117 is provided with guide portions 118 that penetrate laterally through the skirt wall 117 and the main body connection portion 114, and three guide portions 118 are evenly spaced in the circumferential direction around the insertion hole 112. Furthermore, the guide portion 118 is provided with groove-shaped support slits 119.

[0022] The nozzle 124 has a stem fitting portion 125 that fits onto the stem S, a discharge cylinder 126 that communicates with the stem S, and a discharge port 127 that communicates with the stem S via the discharge cylinder 126. On the outer circumferential surface of the discharge cylinder 126, there are three projections 128 and three operating contact portions 129 that project radially outward, arranged alternately and evenly in the circumferential direction around the discharge cylinder 126. A curved guide interference surface 129a is formed between the protruding portion 128 and the operated contact portion 129. The upper surface of the contact portion 129 is gradually inclined downward toward the radially outward direction. With the nozzle 124 fitted onto the stem S, the protruding portion 128 is positioned to slide vertically within the operating guide 116 of the main body portion 110. Furthermore, the discharge port 127 is located above the upper surface of the top plate portion 111.

[0023] The operating section 130 is shaped like a button and has a push-in portion 131, an operating contact portion 132 located opposite the push-in portion 131, and a sliding projection 134. The operating contact portion 132 is provided with an operating inclined surface 133 on its lower side that gradually slopes downward toward the push-in portion 131, and it constitutes the nozzle operating mechanism 135 with the operated contact portion 129 of the nozzle 124. The operating unit 130 is inserted into the guide portion 118 of the main body 110 so as to be able to move forward and backward. At this time, the sliding projection 134 is slidably positioned within the support slit 119.

[0024] Next, the procedure for spraying the contents M of an aerosol product P equipped with an aerosol actuator 100 according to one embodiment of the present invention will be explained with reference to Figures 3 and 10. In this embodiment, the contents M are described as being dispensed in a foamy form, but the form in which the contents M are dispensed is not limited to this, and may be dispensed in a gel-like or cream-like form, for example.

[0025] First, with the aerosol product P stationary, when the push-in portion 131 of the operating portion 130 is pushed from the side toward the nozzle 124, the operating portion 130 moves toward the nozzle 124 without changing its height, with the sliding projection 134 being supported by the support slit 119. At this time, you may press in only one of the operating parts 130, or you may press in all of the operating parts 130 simultaneously. Furthermore, since the three operating parts 130 are evenly arranged circumferentially around the insertion hole 112, the actuator can be operated in the same way from any direction in the circumferential direction, eliminating the need to rotate the aerosol product P to adjust its orientation during use.

[0026] Furthermore, by holding the aerosol product P with one hand, wrapping it around the outer surface of the skirt wall 117, and then applying pressure to push the operating section 130, the operating section 130 can be operated with only one hand while supporting the aerosol product P. Because the nozzle operating mechanism 135 has an operated contact portion 129 and an operating inclined surface 133 in contact with each other, as the operating portion 130 is moved toward the nozzle 124, the nozzle 124 gradually moves downward. This pushes down the stem S into which the nozzle 124 is fitted, releasing the blockage in the flow path (not shown) within the stem S, and the contents M in the aerosol container C are sprayed out. In this case, since the protruding portion 128 is positioned to slide vertically within the operating guide, movement of the nozzle 124 in directions other than vertical can be restricted. For example, even when operating only one of the operating units 130, it is possible to prevent the nozzle 124 from tilting in the direction pushed by the operating unit 130, and the stem S will not be pushed in at an angle, preventing it from being pushed in insufficiently or deforming. In this embodiment, when only one of the operating units 130 is operated, the guide interference surface 129a comes into contact with the guide wall 116b, which further prevents the nozzle 124 from tilting and makes it easier to move the nozzle 124 downward.

[0027] The contents M are discharged from the discharge port 127 through the discharge cylinder 126 to the upper surface of the top plate portion 111. The foamy contents M discharged from the discharge port 127 pass through the communication hole 121 and land on the nozzle cover 120. Depending on the shape and amount of contents M discharged, some of the contents M may also land on the top plate portion 111, enveloping the nozzle cover 120. After discharging the required amount of contents M, when the operating section 130 is released, the stem S rises due to the restoring force of an elastic member (not shown) provided inside the valve unit ∨, and the flow path (not shown) of the stem S is closed again. At this time, the nozzle 124 fitted to the stem S also rises, and the operating part 130, which has its operating inclined surface 133 in contact with the operated contact part 129, also moves in a direction away from the nozzle 124 and returns to the position before the operating part 130 was pushed in. Furthermore, by providing a biasing member that biases the operating unit 130 in the direction of detachment from the nozzle 124, the operating unit 130 can be quickly moved back to its initial position after the contents M are discharged, and the timing of the stem S's return is also accelerated, thereby preventing the contents M from being discharged more than necessary.

[0028] The contents M dispensed onto the top plate 111 are scooped up and used by the hand that operated the operating section 130. Furthermore, if only a small amount of contents M that fits on top of the nozzle cover 120 is to be used, the contents M on top of the nozzle cover 120 can be easily scooped up from the bottom of the nozzle cover 120 without leaving any behind.

[0029] As described above, with an aerosol product P equipped with an aerosol actuator 100 according to one embodiment of the present invention, all operations from dispensing the contents M to use can be easily performed with one hand. Furthermore, since the main body 110 having the top plate portion 111 is fixedly attached to the aerosol container C by the fixing portion 115, the relative position between the aerosol container C and the top plate portion 111 does not change even when the contents M are dispensed. Even if force is applied to push down on the top plate portion 111 when scooping up the contents M dispensed onto the top plate portion 111, the nozzle 124 will not be pushed in and the contents M will not be unexpectedly dispensed. Furthermore, although the discharge port 127 protrudes above the upper surface of the top plate portion 111 from the insertion hole 112, an annular projection 113 is provided on the upper surface of the top plate portion 111, and the nozzle cover 120 is fitted onto the annular projection 113. Therefore, fingers or other objects cannot accidentally touch the discharge port 127, thus preventing malfunction of the stem S.

[0030] Furthermore, since a skirt wall 117 is provided on the outer edge of the top plate portion 111, even if the contents M drip from the outer edge of the top plate portion 111, it is possible to prevent the contents M from entering the main body portion 110, and cleaning can be completed simply by wiping the skirt wall 117. Furthermore, as shown in Figure 11, a skirt wall 117b extending to the shoulder portion Cs of the aerosol container C can be formed to more reliably prevent the contents M from entering the main body portion 110.

[0031] In this embodiment, the upper surface of the top plate portion 111 has been described as being formed in a flat shape, but the shape of the upper surface of the top plate portion 111 is not limited to this, and for example, it may be formed in a dome shape that is convex upward, which makes it possible to easily scoop up the contents M discharged around the insertion hole 112 of the top plate portion 111 without leaving any of it on the top plate portion. Furthermore, by configuring the operating inclined surfaces 133 of the multiple operating parts 130 with different inclination angles, the amount of pressure applied to the stem S by the nozzle operating mechanism 135 can be adjusted by pressing the operating part 130, thereby allowing adjustment of the amount and force of the contents M to be discharged.

[0032] Although embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and various design modifications can be made without departing from the present invention as described in the claims.

[0033] In the embodiments described above, the discharge port was assumed to be located above the upper surface of the top plate portion from the insertion hole. However, the relationship between the discharge port and the top plate portion is not limited to this. For example, the discharge port may be located below the upper surface of the top plate portion, and multiple insertion holes may be provided on the top plate portion, with multiple discharge ports corresponding to each insertion hole.

[0034] Furthermore, although the above-described embodiment was explained as having three operating parts evenly arranged in the circumferential direction around the insertion hole, the configuration of the operating parts is not limited to this, and for example, there may be two or more, or multiple operating parts may be concentrated at predetermined positions in the circumferential direction around the insertion hole. Furthermore, in the embodiments described above, it was explained that protrusions and contact parts formed to project radially outward are evenly and alternately arranged in three positions around the discharge cylinder on the outer circumferential surface. However, the arrangement of the protrusions and contact parts is not limited to this. For example, there may be only one protrusion or contact part, multiple protrusions or contact parts may be concentrated at predetermined positions around the discharge cylinder, or there may be no protrusions at all.

[0035] Furthermore, in the embodiments described above, the operating section is provided with a sliding projection, and the sliding projection is configured to slide within the support slit of the guide section. However, the configuration of the operating section and the guide section is not limited to this, and for example, the sliding projection and support slit may be omitted. Furthermore, although the above-described embodiment was explained as having a skirt wall hanging down from the outer peripheral edge of the top plate, the configuration of the main body is not limited to this. For example, there may be no skirt wall, or the skirt wall may hang down from radially inward from the outer peripheral edge of the top plate.

[0036] Furthermore, although the above-described embodiment explained that the main body is attached by fitting the fixing part to the outside of the valve unit of the aerosol container, the method of attaching the main body to the aerosol container is not limited to this. For example, the fixing part may be fitted to the inside of the valve unit of the aerosol container, or the fixing part may be fitted to the body of the aerosol container. Furthermore, in the embodiments described above, the nozzle was provided with a protrusion, and the protrusion was configured to slide within the operating guide of the main body. However, the configuration of the nozzle and the main body is not limited to this. For example, the operating guide may be provided on the nozzle side and the protrusion on the main body side, or neither the protrusion nor the operating guide may be provided.

[0037] Furthermore, in the embodiments described above, the nozzle operating mechanism is composed of an operating contact portion of the operating unit and an operating contact portion of the nozzle, and the nozzle is moved up and down by sliding an operating inclined surface provided on the operating contact portion against an inclined surface of the operating contact portion. However, the configuration of the nozzle operating mechanism is not limited to this, and for example, the operating inclined surface may be provided only on the operating contact portion, and the operating contact portion may be formed in a spherical shape so that the operating contact portion and the operating contact portion slide against each other. Furthermore, in the above-described embodiment, an annular projection was provided on the upper surface of the top plate and the nozzle cover was described as being fitted onto the annular projection. However, the configuration of the top plate and nozzle cover is not limited to this. For example, the nozzle cover may be fitted onto the inner circumferential surface of the insertion hole, the nozzle cover may be integrally formed with the top plate, there may be no nozzle cover, and there may be no annular projection.

[0038] Furthermore, in the embodiments described above, the nozzle is provided with a guide interference surface, and the guide interference surface and the guide wall are described as coming into contact when the operating part is operated. However, the configuration of the nozzle and the main body is not limited to this, and for example, the guide interference surface may not be present. [Explanation of Symbols]
