Description

  The present invention relates to an aerosol button, an aerosol cap, and an aerosol button spray nozzle tip for an aerosol container for spraying a medicine or the like.

  A general aerosol container filled with a content such as a medicine has a valve stem on the upper surface, and the structure is such that the content is jetted by pressing the valve stem. In order to facilitate the pressing of the valve stem, an aerosol button is usually attached to the valve stem. The aerosol button has an injection port and a flow path that communicates the injection port and the valve stem. When the aerosol button is pressed, the valve stem is pressed and the contents are injected from the injection port through the flow path. Is done.

  There are two types of aerosol containers: a type that covers the aerosol button attached to the valve stem in a removable manner with a cap, removes the cap from the aerosol container when in use, and pushes the aerosol button (removable) A type with a button (one-touch type) that pushes the aerosol button while the cap with the button integrated (hereinafter referred to as “aerosol cap”) is attached to the aerosol container and the aerosol cap is still attached to the aerosol container. It has been. Of these, the one-touch type is widely used in recent years because it does not require removal of the cap each time it is used, and the injection operation is simple, and there is no risk of losing the cap. 1).

  17 and 18 show a one-touch type aerosol button described in Patent Document 1. FIG. The aerosol button 100 is provided integrally with a cap body 102 of an aerosol cap 101 made of synthetic resin. The cap body 102 includes a mounting portion 103 that is mounted on the aerosol container, and a pair of left and right side wall portions 104 that rise from both side portions of the mounting portion 103. The aerosol button 100 is positioned between both side wall portions 104 and is supported by the upper wall portion 103A of the mounting portion 103 positioned in front of the lower portion of the aerosol button 100 so as to be vertically rotatable via a hinge piece 105. . The aerosol button 100 includes an injection port 106, a flow channel 107 that communicates the injection port 106 and the valve stem, and a pair of upper and lower protruding pieces 108 that extend in the injection direction from the end surface on the injection port 106 side. The first flow path 107A communicates with the valve stem, and the second flow path 107B extends to the injection port 106 at right angles to the first flow path 107A. The center O of the injection port 106 is located on a horizontal plane G passing through the center in the vertical direction of the gap between the protruding pieces 108. The contents injected from the injection port 106 through the flow path 107 from the valve stem pass through the gap 109 between the two projecting pieces 108, so that the diffusion in the vertical direction is restricted and the content in the horizontal direction is limited. Diffusion is allowed and sprayed at a wide angle in the horizontal direction.

  In the aerosol button 100 described in Patent Document 1, the injection port 106 is positioned at a substantially central portion (near the valve stem) of the cap body 102, and accordingly, the second flow channel 107B has the injection port 106 that is a cap. Compared with the case where it is located in the vicinity of the peripheral edge of the main body 102, its length is shorter. Here, when the aerosol cap 101 is resin-molded, a first mold for molding a first channel that is die-cut along the first channel 107A and a second channel in a direction away from the first channel 107A. A second mold for forming a second flow path that is die cut along 107B is used. The second mold has a shape having a thin needle-like portion for forming the injection port 106 and the second flow path 107B. By positioning the injection port 106 at a substantially central portion of the cap body 102, the second mold is formed. The dimension of the needle-like portion of the second mold can be shortened. Thus, in the aerosol button 100 described in Patent Document 1, it is possible to prevent damage such as bending or breaking of the needle-shaped portion of the second mold when the aerosol cap 101 is resin-molded. Molding is possible.

Japanese Patent No. 4680321

  In the aerosol button 100 described in Patent Document 1 described above, when the contents are ejected vigorously from the ejection port 106, generally, in the vicinity of the ejection port 106, a pressure drop occurs due to the ejection flow from the ejection port 106. As a result of the pressure drop, an air flow from the periphery of the injection port 106 to the vicinity of the injection port 106 is generated, so that the pressure drop state generated in the vicinity of the injection port 106 is relieved.

  However, in the aerosol button 100 described in Patent Document 1, the injection port 106 is located at a substantially central portion of the aerosol cap 101, and the upper side of the injection port 106 is open, while the lower side of the injection port 106 is below. An upper wall portion 103A of the mounting portion 103 that covers a part of the upper surface of the aerosol container is provided. Therefore, when the contents are ejected from the ejection port 106, a downward air flow from the periphery toward the vicinity of the ejection port 106 is smoothly generated above the ejection port 106, while below the ejection port 106. The presence of the upper wall portion 103A of the mounting portion 103 hinders upward air flow from the periphery toward the vicinity of the injection port 106. As a result, the downward air flow toward the vicinity of the injection port 106 becomes stronger than the upward air flow toward the vicinity of the injection port 106, so that the air flow described above is generated above and below the injection port 106. This causes a difference in the force acting on the jet flow. Therefore, the jet flow jetted from the jet port 106 is affected by the downward air flow described above, and flows downward from the horizontal direction. There was a problem that liquid dripping may occur due to adhesion to the upper wall portion 103A.

  The present invention has been made paying attention to the above-described problems, and a pair of protruding pieces extending in the injection direction to the injection port in order to inject the contents at a wide angle while the injection port is provided in the vicinity of the valve stem. The aerosol button, aerosol cap, and aerosol button spray nozzle tip provided with an aerosol button, an aerosol cap, and an aerosol button that can effectively prevent the content sprayed from the spray port from adhering to the lower front of the spray port An object is to provide a nozzle tip for spraying an aerosol button.

  An object of the present invention is to provide an aerosol button connectable to a valve stem of an aerosol container, an injection port capable of injecting the contents of the aerosol container, a flow path communicating the injection port and the valve stem, A pair of upper and lower projecting pieces that are provided so as to extend in the ejection direction from the peripheral edge and diffuse the contents ejected from the ejection port in the lateral direction, and both the projecting pieces are in a vertical sectional view in the vertical direction; The shape is determined so that the area of the region above the horizontal plane passing through the center of the injection port of the horizontally extending gap formed between the projecting pieces is larger than the area of the region below the horizontal plane. This is achieved by an aerosol button characterized in that.

  According to the aerosol button having the above configuration, since the area of the region above the horizontal plane passing through the center of the injection port in the gap between both protruding pieces is larger than the area of the region below the horizontal plane, the contents injected from the injection port are When passing through the gap, the downward diffusion is restricted, whereas the upward diffusion is allowed accordingly. As a result, since the jet from the gap between the two projecting pieces flows upward from the horizontal direction, the jetted contents adhere to the mountain cap of the aerosol container or the upper wall of the aerosol cap body in front of the lower part of the jet port. Is prevented.

  In a preferred embodiment of the aerosol button according to the present invention, the two projecting pieces have a vertically symmetric shape in a vertical sectional view in the vertical direction, and a horizontal plane passing through the center in the vertical direction of the gap between the two projecting pieces. Is positioned with respect to the injection port so as to be positioned above a horizontal plane passing through the center of the injection port.

According to the aerosol button having the above configuration, the mold for manufacturing the aerosol button having the above configuration can be easily manufactured by simply shifting the positions of both protrusions upward with respect to the injection port in the conventional manufacturing mold. be able to.

  In a further preferred embodiment of the aerosol button according to the present invention, the flow path includes a first flow path communicating with the valve stem of the aerosol container, one end communicating with the first introduction path and the injection port at the other end. And the second flow path is formed so that the injection port is positioned in the vicinity of the first flow path.

  According to the aerosol button having the above configuration, since the injection port is formed so as to be positioned in the vicinity of the first flow path, the needle shape of the mold for forming the injection port at the time of resin molding of the aerosol cap It is possible to prevent breakage such as bending or bending of the portion, and safe and reliable molding becomes possible.

  In general, when the injection port is formed so as to be located in the vicinity of the first flow path, the distance from the injection port to the outer peripheral edge portion (winding portion) of the aerosol container is increased, and the lower portion of the injection port is moved forwardly. Increased risk of content sticking. However, according to the aerosol button having the above-described configuration, the injection from the gap between the two projecting pieces flows upward from the horizontal direction, and the contents are prevented from adhering to the lower front part of the injection port. It is possible to provide an aerosol button that can prevent the mold from being damaged and that prevents the contents from adhering to the lower front of the injection port.

  The above object of the present invention is also achieved by an aerosol cap characterized in that the aerosol button having the above structure and a cap body are provided integrally.

  Further, the above object of the present invention is to provide an injection nozzle chip to be inserted into an aerosol button injection port, from an insertion portion to be inserted into an aerosol button injection port, and a chip body provided integrally with the insertion portion. The tip body is provided with a jet port communicating with the jet port, and a pair of upper and lower portions that are provided so as to extend in the jet direction from a peripheral portion of the jet port and diffuse the contents jetted from the jet port in the lateral direction. Each projecting piece, in the vertical cross-sectional view in the vertical direction, the area of the region above the horizontal plane passing through the center of the jet outlet of the horizontally extending gap formed between the both projecting pieces It is also achieved by an aerosol button spray nozzle tip characterized in that the shape is determined so as to be larger than the area of the region below the horizontal plane.

  According to the nozzle tip for injection having the above-described configuration, the injection from the gap between the two protruding pieces flows upward rather than in the horizontal direction simply by mounting this on the injection port of the aerosol button. It is prevented that the aerosol cap adheres to the mountain cap of the aerosol container in front of the lower portion of the injection port or the upper wall portion of the aerosol cap body.

  According to the aerosol button, the aerosol cap, and the spray nozzle tip of the aerosol button according to the present invention, it is possible to effectively prevent the content sprayed from the spray port from adhering to the lower front of the spray port. .

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The same or similar parts in the drawings are denoted by the same reference numerals and description thereof is partially omitted.

  FIG. 1 shows an external configuration of an aerosol cap equipped with an aerosol cap having an aerosol button according to an embodiment of the present invention. 2 to 6 show an external configuration and an internal configuration of the aerosol cap of FIG. In addition, below, the injection direction side of the content in an aerosol button is demonstrated as a front side, and the opposite side to an injection direction is demonstrated as a rear side.

  The aerosol container 10 has a general form in which the upper part of a bottomed cylindrical can 11 is closed with a mounting cup 12 and a valve stem 13 is provided at the center thereof. The outer peripheral edge of the upper portion of the can body 11 is a winding fastening portion 14 between the can body 11 and the mounting cup 12, and the aerosol cap 1 is attached to the winding fastening portion 14. The aerosol cap 1 is normally used in a state where it is attached to the aerosol container 10.

  The aerosol cap 1 is made of synthetic resin, and is provided integrally with a cap body 2 having a mounting portion 20 that can be mounted on the aerosol container 10 and a pair of left and right side walls 21 and 21 that extend upward from the mounting portion 20. And an aerosol button 3 connected to the valve stem 13 of the aerosol container 10. The aerosol button 3 has a circular injection port 4 through which the contents of the aerosol container can be injected, and when the aerosol button 3 is pressed down, the valve stem 13 is pressed and the content is injected from the injection port 4. . In the present embodiment, the injection port 4 is provided in the vicinity of the valve stem 13 at a substantially central position of the aerosol cap 1.

  The mounting part 20 of the cap body 2 has a cylindrical shape and can be attached to and detached from the winding part 14 of the aerosol container 10 by elastically deforming the lower end part. Both side walls 21 of the cap body 2 include an outer wall 21A, a top wall 21B extending radially inward from the upper end of the outer wall 21A, an inner wall 21C extending downward from the top wall 21B, and a front end wall 21D. . Each front end wall 21 </ b> D is connected to the upper wall portion 20 </ b> A of the mounting portion 20 that covers a part of the upper surface of the aerosol container 10. Each side wall 21 has an end on the injection direction side (front side) and an end on the opposite side (rear side) to the injection direction, and has gaps 22A and 22B between the ends. The rear gap 22B is for allowing the user's finger to reach the aerosol button 3 when the user presses the aerosol button 3 during use, and is formed in a size that allows the finger to be inserted. ing. An injection port 4 for the aerosol button 3 is provided in the front gap 22A. The front end walls 21 </ b> D of the side wall portions 21 are separated from each other toward the outer wall 21 </ b> A from the inner wall 21 </ b> C, and extend radially around the injection port 4. As a result, even if the contents ejected from the ejection port 4 are ejected in the form of a wide-angle fan in the lateral direction via both projecting pieces 5 as will be described later, the contents contact and adhere to the front end wall 21D. Is prevented.

  The distance L (shown in FIG. 2) between the outer end portions of the front end walls 21D that are separated from each other is preferably 20 mm or more, and more preferably 43 mm or more. If the distance L is smaller than 20 mm, the effect of preventing the content ejected from the ejection port 4 from contacting the front end wall 21D cannot be sufficiently obtained. On the other hand, if the distance L is 43 mm or more, the effect of preventing the content from contacting the front end wall 21 </ b> D is sufficiently obtained even when the lateral injection angle of the content injected from the injection port 4 is particularly increased. Can be obtained.

  The side wall portions 21 are integrally provided with flanges 23. The flange portion 23 extends in an arc shape on the front gap 22 </ b> A of the side wall portions 21, and both ends thereof are connected to the upper end portions of the side wall portions 21. Even if the front end walls 21 </ b> D of the side wall portions 21 are separated from each other to prevent contact with the contents ejected from the ejection port 4, the user accidentally moves the finger from the ejection direction side. Is allowed to reach the aerosol button 3. Note that a gap 24 is provided between the collar portion 23 and the aerosol button 3 so that the collar portion 23 does not get in the way when the user normally reaches the finger on the aerosol button 3 from the side opposite to the injection direction. Is provided.

  Reinforcing ribs 25 are integrally provided on the lower surface of the flange 23. The reinforcing rib 25 extends in an arc shape along the flange portion 23, and both end portions are connected to the side wall portions 21. The reinforcing rib 25 strengthens the resistance force to the external force that acts on the flange portion 23. In particular, since the flange portion 23 extends long in the extending direction between the side wall portions 21, the reinforcing rib 25 extending in this direction efficiently imparts a counter force against an external force. Further, since both end portions of the reinforcing rib 25 are connected to the side wall portion 21, the external force acting on the reinforcing rib 25 is also supported by the side wall portion 21, and the reinforcing effect becomes higher. Furthermore, when the aerosol container is packaged with the shrink film, the shrink film is supported by the flange portion 23 between the side wall portions 21, thereby preventing occurrence of wrinkles and breakage.

  In addition, a raised portion 26 is integrally provided at the center of the rear surface of the flange portion 23 in the length direction. The central portion of the flange portion 23 is a location where the resin flowing into the mold meets during the resin molding from the both side wall portions 21 side. Therefore, a weld line is likely to be generated, and even if the weld line does not occur, it is local. May cause a significant decrease in strength. The raised portion 26 functions to secure strength by concentrating the resin here.

  The aerosol button 3 is provided between both side wall portions 21 of the cap body 20, and the front end lower portion of the aerosol button 3 is connected to a hinge piece 27 extending from the upper wall portion 20 </ b> A of the mounting portion 20. Thereby, the aerosol button 3 can be rotated in the vertical direction around the hinge piece 27, and is rotated downward to press the valve stem 13 by being pushed down by a finger. On the other hand, by releasing the push-down of the aerosol button 3 by the finger, the aerosol button 3 is rotated upward to return to the original position, and the pressure of the valve stem 13 is released.

  As shown in FIGS. 7 to 9, the aerosol button 3 includes an upper wall 30, a front wall 31, a rear wall 32, and a pair of left and right side walls 33, and a lower surface is open. A recess 38 (shown in FIG. 3) is formed in the rear wall 32 of the aerosol button 3. Correspondingly, a convex portion 28 that can be fitted into the concave portion 38 is integrally provided on the rear side of the mounting portion 20 of the cap body 2. When the aerosol button 3 is pushed down, the projection 28 is engaged with the recess 38, whereby the aerosol button 3 is guided and rotated downward.

  The front wall 31 of the aerosol button 3 is thick, and a valve stem insertion hole 34 is formed in the thick portion. The lower end portion of the valve stem insertion hole 34 is formed in a tapered shape that extends downward, so that the valve stem 13 can be easily inserted. The upper end of the valve stem insertion hole 34 is continuous with the lower end of the first flow path 35 through which the contents ejected from the valve stem 13 pass. The first flow path 35 extends in the vertical direction and has a closed portion 39 whose upper end is closed. The first flow path 35 is formed in a tapered shape, whereby the content ejected from the valve stem 13 can be efficiently guided to the ejection port 4.

  A step portion 36 is provided between the valve stem insertion hole 34 and the first flow path 35. This step portion 36 functions as a stopper for the valve stem 13 to be inserted. The valve stem insertion hole 34 and the first flow path 35 are not provided with an enlarged diameter portion on the way, and thus the first mold (not shown) for forming the first flow path is directed downward (arrow J shown in FIG. 8). (In the direction of) can be released.

  The aerosol button 3 is formed with a second flow path 37 so as to be orthogonal to the first flow path 35. The second flow path 37 has one end communicating with the first flow path 35 and the other end extending horizontally to penetrate the front wall 31. In the present embodiment, the columnar body 40 is integrally projected on the front wall 31, and the other end of the second flow path 37 opens through the columnar body 40, so that the content injection port 4. Is configured. The column body 40 ensures the length of the second flow path 37 and stabilizes the injection of the contents from the injection port 4. In the present embodiment, the column body 40 has a cylindrical shape, but may be various columnar shapes such as an elliptical column, a long column, a rectangular column, a hexagonal column, and an octagonal column. The column body 40 can be omitted. In this case, the content injection port 4 is formed on the end face of the front wall 31.

  The length of the second flow path 37 is set so that the injection port 4 is located in the center of the cap body 2, that is, in the vicinity of the first flow path 35 (valve stem 13). When the aerosol cap 1 is resin-molded, a first mold for molding a first channel (not shown) that is die-cut along the first channel 35 and a second direction away from the first channel 35. A second mold (not shown) for second flow molding that is die cut along the flow path 37 is used. The second mold has a shape with a thin needle-like portion for forming the injection port 4 and the second flow path 37, but the injection port 4 is positioned in the vicinity of the first flow path 35. Thereby, the dimension of the acicular part of the second mold can be shortened. As a result, it is possible to prevent breakage such as bending or breaking of the needle-shaped portion of the second mold, and safe and reliable molding is possible.

  On the end surface of the front wall 31, a pair of upper and lower protruding pieces 5, 5 extending in the injection direction are integrally provided on the peripheral edge of the injection port 4. Both projecting pieces 5 are arranged to face each other with a predetermined interval, and a gap 50 extending in the horizontal direction is formed between the projecting pieces 5. The two protruding pieces 5 restrict the diffusion in the vertical direction and allow the diffusion in the horizontal direction when the contents injected from the injection port 4 pass through the gap 50 between the two protruding pieces 5. Thereby, the content injected from the injection port 4 is injected from both the protrusion pieces 5 as the fan-shaped injection flow F (shown in FIG. 2) which is a wide angle in the horizontal direction. Both projecting pieces 5 can adjust the lateral spread of the jet flow F by appropriately setting the projecting length in the jetting direction or the vertical facing distance.

  In the present embodiment, as shown in FIG. 10, the two projecting pieces 5 are symmetrical in shape in the vertical sectional view in the vertical direction orthogonal to the injection direction, and between the opposing edge portions 51 of each projecting piece 5. A gap 50 is formed. The central portion of the opposing edge portion 51 of each protruding piece 5 is cut out in an arc shape so as to follow the outer shape of the opposing circular injection port 4. Both projecting pieces 5 are located with respect to the injection port 4 such that a horizontal plane G1 passing through the center in the vertical direction of the gap 50 between the two projecting pieces 5 is positioned above a horizontal plane G2 passing through the center O of the injection port 4. It is positioned. Thereby, in a vertical cross-sectional view in the vertical direction, the area S1 of the region above the horizontal plane G2 passing through the center of the injection port 4 of the gap 50 formed between the projecting pieces 5 is larger than the area S2 of the region below the horizontal plane G2. It is getting bigger.

  In the prior art, the horizontal plane G1 passing through the center in the vertical direction of the gap 50 between the projecting pieces 5 and the horizontal plane G2 passing through the center O of the injection port 4 are coincident, that is, the center of the injection port 4 in the gap 50. The area S1 of the region above the horizontal plane G2 passing through the same area as the area S2 of the region below the horizontal plane G2 is the same as the area S2 of the region below the horizontal plane G2. Therefore, the jet flow F ejected from both projecting pieces 5 mainly flows in the horizontal direction. Therefore, when the jet flow F passes over the upper wall portion 20A of the cap body 2, it is influenced by the air flow (air flow), and thus flows downward from the horizontal direction. As a result, the jet flow F is jetted. The contents sometimes adhered to the upper wall portion 20A of the cap body 2.

  On the other hand, when the area S1 of the region above the horizontal plane G2 passing through the center of the injection port 4 of the gap 50 between the projecting pieces 5 is larger than the area S2 of the region below the horizontal plane G2 as in this embodiment, the injection port 4, while the contents of the aerosol container injected from 4 are limited to the downward diffusion when passing through the gap 50, the upward diffusion is allowed. The jet flow F injected from the piece 5 flows upward from the horizontal direction. Therefore, even when the jet flow F is affected by the air flow (air flow) when passing over the upper wall portion 20A of the cap body 2, the jet flow F is in the horizontal direction or above the horizontal direction. Therefore, the injected contents are prevented from adhering to the upper wall portion 20A of the cap body 2.

  In addition, in the aerosol cap 1 having the above-described configuration, when the cap body 2 does not include the upper wall portion 20A, the mountain cup 12 of the aerosol container 10 is similar to the upper wall portion 20A and the content from the injection port 4 is the same. During the injection of an object, the flow of air from the periphery of the injection port 4 toward the vicinity of the injection port 4 is inhibited. Therefore, when the aerosol button 3 of the present invention is used, even when the cap body 2 is not provided with the upper wall portion 20A, the contents adhere to the mountain cup 12 positioned in front of the lower portion of the injection port 4 and the liquid dripping. Can be prevented.

  In order to use the aerosol cap 1 having the above-described configuration, the mounting portion 20 is mounted on the winding portion 14 above the can body 11 of the aerosol container 10. As a result, the valve stem 13 of the aerosol container 10 is inserted into the valve stem insertion hole 34. Then, the valve stem 13 is pressed by placing a finger on the aerosol button 3 from the rear gap 22B between the side walls 21 and pressing the aerosol button 3. As a result, the contents of the aerosol container 10 are ejected in the horizontal direction from the ejection port 4 through the first flow path 35 and the second flow path 37, and pass through the gap 50 between the projecting pieces 5. Are injected as a jet flow F diffused in a wide angle. Thereafter, when the push-down of the aerosol button 3 is released, the aerosol button 3 is elastically returned to the original position, the pressure on the valve stem 13 is released, and the injection of the contents is stopped.

  FIG. 11 shows an embodiment of an aerosol container provided with the aerosol cap 1 having the above-described configuration. In the illustrated aerosol cap 1, the cap body 2 has an outer diameter of 60 mm and a height of 50 mm, and the aerosol button 3 has a front and rear length of 30 mm, a left and right width of 22 mm, and a height of 12 mm. The column 40 has a diameter of 1.5 mm, and a protruding length in the injection direction of 0.5 mm. The injection port 4 and the second flow path 37 have a diameter of 0.75 mm, and the protruding piece 5 has a width of 1.2 mm. The protrusion length in the injection direction is 2.5 mm, and the maximum distance l (see FIG. 10) between the opposing edge portions 51 is 1.4 mm. Further, in the aerosol cap 1 of FIG. 10, the horizontal plane G1 passing through the center in the vertical direction of the gap 50 between the projecting pieces 5 is located 0.05 mm above the horizontal plane G2 passing through the center O of the injection port 4. (See FIG. 10). FIG. 12 shows an aerosol container provided with a conventional aerosol cap 101 as a comparative example. In the aerosol cap 101 of FIG. 12, the horizontal plane G1 passing through the center in the vertical direction of the gap between the projecting pieces and the horizontal plane G2 passing through the center O of the injection port are located at the same height.

  As can be seen from FIG. 11, when the aerosol cap 1 of the present embodiment is mounted on the aerosol container 10, compared to the case where the aerosol cap 101 of the prior art illustrated in FIG. 12 is mounted on the aerosol container, The jet flow F hardly flows downward from the horizontal direction and flows from the horizontal direction or upward from the horizontal direction. It was confirmed that almost nothing was attached. The dimension values of the aerosol cap 1 and the aerosol button 3 described above can be changed as appropriate according to the function and application of the aerosol container 10 or the aerosol cap 1.

  As described above, according to the aerosol cap 1 and the aerosol button 3 of the present embodiment, the contents can be ejected upward from the horizontal direction while enabling the wide-angle ejection of the contents in the lateral direction. Therefore, a large amount of contents can be ejected far, and dripping due to the contents adhering to the lower front of the ejection port 4 can be effectively prevented.

  In addition, according to the present embodiment, in the conventional mold for molding an aerosol cap (aerosol button), the aerosol cap 1 having the above-described configuration can be obtained by simply shifting the positions of both protrusions 5 with respect to the injection port 4. A molding die for the (aerosol button 3) can be easily manufactured.

  Moreover, according to this embodiment, since the injection port 4 is formed so as to be positioned in the vicinity of the first flow path 35, the second gold for forming the injection port 4 at the time of resin molding of the aerosol cap 1. It is possible to prevent breakage such as bending or breaking of the needle-shaped portion of the mold, and safe and reliable molding is possible. In general, when the injection port 4 is formed so as to be positioned in the vicinity of the first flow path 35, the distance from the injection port 4 to the winding portion 14 of the aerosol container 10 becomes long, and the content of the injection port 4 toward the lower front side The risk of object adhesion increases. However, according to the aerosol cap 1 and the aerosol button 3 of the present embodiment, the jet from the gap 50 between the projecting pieces 5 flows upward from the horizontal direction, and the contents adhere to the lower front part of the jet port 4. Therefore, the aerosol cap 1 and the aerosol button 3 that can prevent the mold from being damaged and can prevent the contents from adhering to the lower front of the injection port 4 are provided. Can be provided.

  As mentioned above, although one Embodiment of this invention was described, the specific aspect of the aerosol button and aerosol cap which concerns on this invention is not limited to above-described embodiment. For example, in the above-described embodiment, the outer shapes of the projecting pieces 5 are symmetrical in the vertical direction, but the outer shapes of the projecting pieces 5 may be different shapes in the upper and lower sides. FIG. 13 shows another embodiment of the protruding pieces 5. In the protruding piece 5 of this embodiment, the opposing edge portion 51A of the lower protruding piece 5 is formed in a horizontal shape, whereas the opposing edge portion 51B of the upper protruding piece 5 protrudes downward. It is formed in a shape. In the illustrated example, it is curved in a convex shape, but is not necessarily limited thereto. The central portions of the opposing edge portions 51A and 51B of each protruding piece 5 are cut out in an arc shape so as to follow the outer shape of the opposing circular injection ports 4.

  In this embodiment, at least the imaginary line P that describes the outer shape of the injection port 4 and the opposing edge 51B of the upper protruding piece 5 are as much as the opposing edge 51B of the upper protruding piece 5 protrudes downward. If the center Z between the intersection X and the imaginary line P of the injection port 4 and the intersection Y of the opposing edge 51A of the lower protruding piece 5 is located above the horizontal plane G2 passing through the center O of the injection port 4 In the vertical sectional view in the vertical direction, the area S1 of the region above the horizontal plane G2 passing through the center of the injection port 4 of the gap 50 formed between the projecting pieces 5 is larger than the area S2 of the region below the horizontal plane G2. . Therefore, in this embodiment as well, the content of the aerosol container injected from the injection port 4 is limited to the downward diffusion when passing through the gap 50, whereas the content is increased upward. Therefore, the jet flow F ejected from both protruding pieces 5 flows upward in the horizontal direction. As a result, even when the jet flow F is affected by the air flow (air flow) when passing over the upper wall portion 20A of the cap body 2, the jet flow F is in the horizontal direction or above the horizontal direction. It flows toward. Therefore, the contents can be ejected horizontally or upward from the horizontal direction while allowing the contents to be ejected in a wide angle in the lateral direction, so that a large amount of contents can be ejected far. In addition, dripping due to the contents adhering to the lower front of the injection port 4 of the aerosol cap 1 can be effectively prevented.

  FIG. 14 shows still another embodiment of both protruding pieces 5. The protruding piece 5 of this embodiment has a shape in which the opposing edge portion 51C of the upper protruding piece 5 protrudes downward, and the opposing edge portion 51D of the lower protruding piece 5 has a shape recessed downward. doing. In the illustrated example, the gap 50 formed by the opposing edge portions 51C and 51D is substantially V-shaped, but may be curved in a substantially U-shape. The central portions of the opposing edge portions 51C and 51D of each protruding piece 5 are cut out in an arc shape so as to follow the outer shape of the opposing circular injection ports 4.

  In this embodiment, the opposing edge 51C of the upper protruding piece 5 protrudes downward, and the opposing edge 51D of the lower protruding piece 5 is recessed downward. The area S1 of the region above the horizontal plane G2 passing through the center of the injection port 4 of the gap 50 formed between the projecting pieces 5 is larger than the area S2 of the region below the horizontal plane G2. Therefore, in this embodiment as well, the content of the aerosol container injected from the injection port 4 is limited to the downward diffusion when passing through the gap 50, whereas the content is increased upward. Therefore, the jet flow F ejected from both protruding pieces 5 flows upward in the horizontal direction. As a result, even when the jet flow F is affected by the air flow (air flow) when passing over the upper wall portion 20A of the cap body 2, the jet flow F is in the horizontal direction or above the horizontal direction. It flows toward. Therefore, the contents can be ejected horizontally or upward from the horizontal direction while allowing the contents to be ejected in a wide angle in the lateral direction, so that a large amount of contents can be ejected far. In addition, dripping due to the contents adhering to the lower front of the injection port 4 of the aerosol cap 1 can be effectively prevented.

  In addition, the external shape of both the protruding pieces 5 is not limited to the above-described embodiment, and the horizontal plane G2 passing through the center of the injection port 4 of the gap 50 formed between the protruding pieces 5 in a vertical sectional view in the vertical direction. If the shape is determined so that the area S1 of the upper region is larger than the area S2 of the lower region than the horizontal plane G2, it can be formed in various shapes.

  In the embodiment described above, in order to push down the valve stem 13 of the aerosol container 10, the aerosol button 3 attached to the valve stem 13 is provided integrally with the cap body 2 attached to the aerosol container 10 and is connected to the aerosol cap 1. However, only the aerosol button 3 may be provided alone and attached to the valve stem 13 of the aerosol container 10. In this case, it is desirable that a cap that covers the aerosol button 3 attached to the valve stem 13 is detachably attached to the aerosol container 10. Also in this embodiment, since the injection flow F of the contents injected from both the projecting pieces 5 flows in the horizontal direction or upward from the horizontal direction, the contents flow into the mounting cup 12 at the upper part of the aerosol container 10. An object can be effectively prevented from adhering.

  15 and 16 show an aerosol button spray nozzle tip (hereinafter simply referred to as “nozzle tip”) according to an embodiment of the present invention. The nozzle tip 6 is capable of diffusing the contents ejected from the ejection port 4 in the lateral direction at a wide angle by being mounted on the ejection port 4 of the aerosol button 3. In this embodiment, No protruding piece is provided on the peripheral edge of the injection port 4 of the aerosol button 3.

  The nozzle tip 6 includes a cylindrical insertion portion 60 that is inserted into the injection port 4 of the aerosol button 3 and a plate-like tip body 61 that is provided integrally with the insertion portion 60. The chip body 61 is formed with an ejection port 62 that communicates with the ejection port 4 of the aerosol button 3 through the internal space of the insertion portion 60. A pair of upper and lower projecting pieces 5 and 5 extending in the ejection direction are integrally provided on the plate surface opposite to the plate surface on which the insertion portion 60 of the chip body 61 is provided. Both projecting pieces 5 are arranged to face each other with a predetermined interval, and a gap 50 extending in the horizontal direction is formed between the projecting pieces 5. In the illustrated example, the two projecting pieces 5 are vertically symmetrical in vertical sectional view in the vertical direction orthogonal to the injection direction, and a gap 50 is formed between the opposing edge portions 51 of each projecting piece 5. A central portion of the opposing edge portion 51 of each protruding piece 5 is cut out in an arc shape so as to follow the outer shape of the opposing circular jet port 62.

  Also in this nozzle tip 6, both projecting pieces 5 are positioned such that the horizontal plane G 1 passing through the center in the vertical direction of the gap 50 between both projecting pieces 5 is located above the horizontal plane G 2 passing through the center O of the jet outlet 62. , Is positioned with respect to the jet port 62 (see FIG. 10). Thereby, in the vertical sectional view in the vertical direction, the area S1 of the region above the horizontal plane G2 passing through the center of the spout 62 of the gap 50 formed between the projecting pieces 5 is larger than the area S2 of the region below the horizontal plane G2. It is getting bigger.

  By mounting the nozzle tip 6 having the above configuration on the injection port 4 of the aerosol button 3, the content injected from the injection port 4 is restricted from being diffused downward when passing through the gap 50. Accordingly, since upward diffusion is allowed, the jet from the gap 30 between the projecting pieces 5 flows upward from the horizontal direction. Therefore, it is possible to effectively prevent the injected contents from adhering to the upper wall portion 20A of the cap body 2 of the aerosol button 3 or the like.

  In addition, the external shape of both the protruding pieces 5 provided in the nozzle chip 6 is not limited to the illustrated example, and is similar to the two protruding pieces 5 provided in the aerosol button 3 described above in the vertical sectional view in the vertical direction. The shape is determined so that the area S1 of the region above the horizontal plane G2 passing through the center of the injection port 4 of the gap 50 formed between the projecting pieces 5 is larger than the area S2 of the region below the horizontal plane G2. If so, it can be formed into various shapes in addition to the shapes shown in FIGS.
