Description

  The present invention relates to an aerosol button attached to an aerosol can having a stem to which a medicine or the like is ejected and capable of pushing the stem, and an aerosol cap provided with the aerosol button.

  Aerosol nozzles attached to aerosol cans include a wide spray nozzle that sprays in a wide-angle spray pattern in addition to a straight spray specification. An example of such a nozzle is disclosed in Patent Document 1. This aerosol nozzle is configured by attaching a nozzle body to a push button. That is, it is formed of two parts. The push button is formed with a stem insertion hole into which the stem of the aerosol can is inserted in the vertical direction, and the stem insertion hole communicates with a horizontal outflow passage formed in the nozzle body. The front end portion of the outflow passage is formed in a circular shape, and a regulating member is attached to the opening to sandwich the opening from both sides. As a result, the aerosol content is restricted in the horizontal injection width, and is diffused only in the vertical direction, whereby the aerosol content is injected in a sector shape having a constant thickness in the horizontal direction. As a result, a spray pattern approximating a rectangular shape is obtained.

JP 2001-205145 A

  However, since the above-described aerosol nozzle is formed by narrowing the tip of the outflow path to a circle, the core of the mold cannot be released in the outflow direction of the outflow path during injection molding. The mold release direction was opposite to the content outflow direction. For this reason, since the core cannot be released from the push button in which the stem insertion hole orthogonal to the outflow path is formed, the push button and the nozzle body cannot be integrally injection-molded. Therefore, there is a problem that the number of parts and the number of assembling steps increase because the push button and the nozzle body must be formed separately and then assembled.

  The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide an aerosol button which can be integrated with a nozzle body and a push button, and which can reduce the number of parts and the number of assembly steps, and an aerosol cap provided with the aerosol button.

  The present invention relates to an aerosol button that is attached to an aerosol can having a stem into which contents are jetted and is capable of pushing in the stem, wherein the button main body is formed with a first outflow path into which the stem is inserted; A second outflow passage that communicates with the first outflow passage; a column that protrudes in a substantially horizontal direction from the button body; and a tip that is attached to a tip of the column at a predetermined interval; A pair of projecting pieces sandwiching the tip opening of the projecting body from the horizontal direction, and a wall body that is attached to the button body and surrounds the column body and the projecting pieces above and on both sides.

  According to this structure, the protrusion piece which pinches | interposes this in the horizontal direction is provided in the opening of the 2nd outflow path in which the content is injected, and, thereby, the width | variety of the path | route of a content is controlled. Therefore, unlike the conventional structure, there is no reduced diameter portion that is narrowed in the outflow direction, and the core in the outflow direction can be released from the second outflow path. Thereby, the wide nozzle hole conventionally provided as a separate part can be formed integrally with the button body.

  Moreover, since the wall body which surrounds the upper side and both sides of the column body which is the ejection part of the contents is provided, there are the following advantages. For example, when the column body is formed integrally with the button body, the column body cannot be protruded long from the button body from the viewpoint of formability. In this case, the column body is formed short, but in this case, the user cannot visually recognize the front end side and the rear end side of the button, and may accidentally push the button main body with a finger from the column body side. Thereby, a pillar and a protrusion piece may be damaged by a finger. On the other hand, in the present invention, since the wall body surrounding the upper side and both sides of the column body is provided, even if the user accidentally pushes the button body with a finger from the column body side, Since the protruding piece is protected, damage can be prevented. In addition to the upper side and both sides of the column body and the protruding piece, the wall body can further surround the lower side. By doing so, the column and the protruding piece can be reliably protected. Further, since the periphery of the column body is surrounded over the entire circumference, it becomes easy to understand that the column body side is the nozzle hole. In particular, since it becomes easy to visually recognize that the column body side is the nozzle hole when viewed from obliquely above, it is possible to prevent such erroneous use as described above.

  In the aerosol button, the wall body can protrude above the upper surface of the button body. If it does in this way, pushing in a button main body with a finger from the pillar side will be prevented by the protruding wall body, and it can prevent improper use. In addition, if you accidentally push the button body with your finger from the column body side, the contents may be ejected toward the hand or human body, but the protruding part of the wall body can ensure that this is the nozzle side , Can prevent misuse.

  In the aerosol button, the lower end portion of the column body can protrude from the upper end portion of the column body. In this way, when the contents are ejected by pressing the button, the lower injection range can be regulated by the lower part of the column body protruding by a predetermined length, and the lower injection range is not excessively widened. Can be. Furthermore, the downward injection range can be easily changed by designing and adjusting the projecting length of the lower part of the column. Further, only the lower part of the column body may be provided without providing the upper part of the column body.

  In the aerosol button, the wall body can be projected by 0.2 to 20 mm from the projecting piece. If the wall body protrudes 20 mm or more from the protruding piece, the injected contents may adhere to the inner wall surface of the wall body. On the other hand, if it is smaller than 0.2 mm, molding may be difficult.

  In the aerosol button, the wall body can be formed integrally with the protruding piece. By carrying out like this, a protrusion piece is reinforced with a wall body and durability improves.

  Further, the present invention is an aerosol cap attached to an aerosol can having a stem from which the contents are jetted, and includes any one of the above-described aerosol buttons, and a cap body detachably attached to the upper end portion of the aerosol can. It is equipped with.

  In the aerosol cap, the cap body can be provided with a pair of side wall portions, and an aerosol button can be disposed between the pair of side wall portions. And a part of wall surface which opposes in a pair of side wall part can comprise so that the ejection channel | path through which the content ejected from the said column passes may be formed. At this time, it is preferable that the narrowest width in the ejection passage is 8 to 16 mm. If it does in this way, it will become difficult to arrange | position a finger to the ejection flow path, and it can prevent incorrect use of pushing a button with a finger from the ejection flow path side.

  In the aerosol cap, the aerosol button and the cap body can be connected and formed integrally. This facilitates the assembly of the parts.

  According to the present invention, the nozzle hole can be integrated with the button, and the number of parts and the number of assembly steps can be reduced.

  The aerosol cap by this embodiment is attached to the aerosol container 507, and injects the contents of a container by button operation. As shown in FIGS. 1 to 3, the aerosol cap includes a cap body 1 that is detachably attached to an upper end portion of an aerosol container 507, and an aerosol button 100 that is integrally connected to the cap body 1. Yes. The aerosol button 100 is provided with a nozzle 3 through which contents are ejected by a pushing operation.

  The aerosol container 507 is a well-known one, and contains a mixture of a stock solution such as a fragrance, a deodorant, and an insecticide and a propellant, and is formed in a cylindrical shape. A thin cylindrical stem (not shown) is attached to the upper end, and when the stem is pushed into the container 507 against a spring (not shown), the valve mechanism below the stem is opened, and the propellant The contents are ejected from the stem by pressure.

  Next, the cap body 1 will be described. As shown in FIGS. 1 to 3, the cap body 1 has an arcuate base end portion 45 that fits around the upper edge of the aerosol container 507, and a pair of side wall portions 51 disposed on the upper portion. . The side wall 51 is formed in a substantially arc shape in plan view, and a space is formed between them. This space is divided into two regions. In FIG. 2, the aerosol button 100 is disposed in the upper region, and the lower region is an injection passage 60 through which the contents to be injected pass. The ejection passage 60 is formed in a fan shape in plan view, and the width is adjusted so that a button cannot be operated by putting a finger into the ejection passage 60. For example, the width S of the region adjacent to the aerosol button 100 is preferably 8 to 16 mm, and more preferably 10 to 14 mm, so that fingers do not enter. Also, a belt-like hinge portion 53 that can be bent up and down is provided at the bottom of the injection passage 60, and the cap body 1 and the aerosol button 100 are connected by the hinge portion 53. Thereby, the aerosol button button 100 can be swung up and down with respect to the cap body 1 and can be pushed downward.

  Next, the aerosol button will be described with reference to FIGS. 4 is a sectional view of the aerosol cap shown in FIG. 1, FIG. 5 is an enlarged perspective view of the vicinity of the nozzle hole shown in FIG. 1, and FIG. 6 is an enlarged perspective view of the nozzle hole shown in FIG. FIG. 7 is an enlarged cross-sectional view of the vicinity of the nozzle hole shown in FIG. In the following description, for convenience of explanation, in the aerosol button, the side on which the injection hole for ejecting the contents is formed is referred to as “front end”, and the opposite direction is referred to as “rear end”. In addition, the injection direction of the contents may be referred to as “front” and the opposite direction may be referred to as “rear”. That is, the left side of FIG. 4 is referred to as the front end, the front side, and the right side as the rear end and rear.

  As shown in FIGS. 4 to 7, the aerosol button 100 includes a block-shaped button body 5 having a hollow inside. A gentle inclined surface 50 is formed on the upper surface of the button body 5 from the front end portion toward the rear end portion, and the inclined surface 50 is pushed in with a finger. In addition, a cylindrical stem receiving portion 7 extending in the vertical direction is provided inside the distal end portion of the button body 5. The stem receiving portion 7 is formed with a stem insertion hole 9 into which the stem is inserted, and a first outflow passage 13 communicating with the stem insertion hole 9. The stem insertion hole 9 is opened at the lower end of the stem receiving portion 7, and the opening becomes a tapered taper 11 to facilitate insertion of the stem. Further, the first outflow passage 13 extends upward from the upper end of the stem insertion hole 9, and the upper end is closed as a closing portion 15.

  The stem insertion hole 9 is formed with a diameter larger than that of the first outflow passage 13, so that a stepped portion 17 is formed at the boundary with the first outflow passage 13. This step portion 17 serves as a stopper for the inserted stem. Further, the stem insertion hole 9 and the first outflow passage 13 are arranged on the same axis, and since there is no enlarged diameter portion in the middle, the mold can be released in the downward direction (not shown). Become.

  Further, a column body 23 extending in the horizontal direction is integrally attached to the distal end surface 19 facing the injection flow path 60 in the button body 5. A second outflow path 21 communicating with the first outflow path 13 is formed in the column body 23. The second outflow passage 21 is formed by a straight hole having the same inner diameter, and is orthogonal to the first outflow passage 13 below the closing portion 15. The second outflow passage 21 communicates with the stem through the first outflow passage 13, and the opening of the second outflow passage 21 formed at the tip of the column body 23 ejects the contents. It has become. In this embodiment, the column body 23 is exemplified as a cylinder shown in FIG. 5, but the column body 23 may be an elliptical column, a long column, a rectangular column, a hexagonal column, an octagonal column, or the like. In addition, the length of the column body 23 in the axis G direction can be set to, for example, 0.3 to 3.0 mm. Moreover, the diameter of the 2nd outflow channel 21 can be 0.4-1.0 mm, for example.

  As shown in FIG. 5, in the column body 23, the tip end surface 25a of the column body lower portion 23a projects forward by a predetermined length L from the tip end surface 25b of the column body upper portion 23b. The boundary line between the column body lower portion 23 a and the column body upper portion 23 b coincides with the diameter line of the column body 23. That is, each of the column body upper portion 23b and the column body lower portion 23a has a semicircular cross section. And the axis G of the 2nd outflow path 21 passes along the diameter line. Thereby, the 2nd outflow channel 21 is formed as a semi-cylindrical hole in both the column lower part 23a and the column upper part 23b. The column lower part 23a protruding forward from the front end surface 25b of the column upper part 23b has the second outflow passage 21 positioned as a semi-cylindrical groove at the center of the virtual rectangular upper surface 27. In the present embodiment, since a protruding piece 29 described later is interposed at the boundary between the column body lower portion 23a and the column body upper portion 23b, the rectangular upper surface 27 does not actually appear on the table, and the lower semicircle of the second outflow passage 21 Only the inner surface 21a is exposed.

  A pair of projecting pieces 29a, 29b projecting along the axis G from the tip surface 19 of the button body is provided at the boundary between the column body lower portion 23a and the column body upper portion 23b. Both projecting pieces 29a, b are arranged at a predetermined interval so as to sandwich the nozzle hole 3 from the horizontal direction, and the tip 31 of each projecting piece 29a, b projects forward from the tip surface 25a of the column body lower part 23a. Yes. In addition, opposed inner surfaces 21 b and 21 c facing each other in the protruding pieces 29 a and b are formed in a circular arc shape along the opening periphery of the second outflow passage 21. In addition, the length of each protrusion piece 29a, b in the axis line G direction can be set to 0.5 to 5.0 mm, for example.

  As described above, the content discharged from the nozzle hole 3 is restricted from moving downward by the column body lower part 23a and restricted from moving sideways by the protruding pieces 29a, b, but is open upward. is doing. And if the contents are discharged before the column body lower part 23a, since the restriction by the column body lower part 23a is eliminated, it is opened up and down. Thereby, the 2nd outflow path 21 is pinched | interposed into the left and right opposing inner surfaces 21b and 21c, and is controlled so that the injection range does not extend in the horizontal direction when the injection is performed. As a result, a rectangular spray pattern having a constant horizontal width is obtained. Further, since the opposing inner surfaces 21b and 21c are parallel inner wall surfaces sandwiching the axis G, the core can be released in the outflow direction of the second outflow passage 21.

  A wall body 33 is attached to the front end surface of the button body 5 so as to surround the protruding piece 29 and the column body 23 and both sides thereof. The wall body 33 is formed in a rectangular shape that is long in the vertical direction, and its upper portion projects upward from the upper surface of the button body 5. Further, the inner wall surface of the wall 33 is connected to and integrated with both ends of the projecting pieces 29a and 29b. Thereby, the protruding pieces 29a and 29b are reinforced, and the injection of the contents can be surely limited in the horizontal direction. Moreover, as shown in FIG. 5, the length of the wall 33 from the front end surface 19 of the button main body 5 is longer than the protruding pieces 29a and 29b. The length of the wall body 33 may be the same. In addition, when making it long, it is preferable that the distance D of the wall body 33 front-end | tip and protrusion piece 29a, b front-end | tip is 0.2-20 mm, and it is further more preferable that it is 0.3-5 mm. This is because if the distance D is too long, the injected contents may adhere to the inner wall surface of the wall 33, and if it is too short, molding may be difficult.

  Next, the operation of the aerosol cap will be described. First, the aerosol button 100 is pushed to inject the contents. In conjunction with this, when the stem is pushed in, the valve mechanism of the aerosol container 507 is opened, and the contents in the aerosol container 507 flow into the first outflow passage 13. The inflowing contents collide with the blocking portion 15 to cause irregular vortex motion and flow into the second outflow path 21. The contents that have flowed into the second outflow path 21 are jetted from the second outflow path 21 that opens at the front end surface 25b of the column upper portion 23b.

  The second outflow channel 21 is sandwiched between the opposed inner surfaces 21b and 21c in front of the front end surface 25b, but the upper side is open, thereby increasing the cross-sectional area of the flow channel. As a result, the contents are decompressed and expanded, and the peeling from the opening edge also acts to diffuse into fine mists and bubbles. The diffused contents are ejected upward from the nozzle 3, and the ejection direction is regulated on both sides by the opposed inner surfaces 21 b and 21 c and is ejected in a fan shape having a certain thickness. Therefore, a wide-angle spray pattern approximating a rectangular shape can be obtained.

The second outflow passage 21 is open at the tip end surface 25b while being closed at the lower semicircular inner surface 21a at a predetermined length L. Therefore, the jet is first diffused upward, and then reaches the tip end surface 25a of the columnar lower portion 23a, so that the lower side is opened for the first time and diffused up and down. That is, the downward injection of the jet at the tip surface 25b of the columnar upper part 23b is suppressed. As a result, as shown in FIG. 7, the downward injection angle θ ₂ becomes a diffusion angle smaller than the upward injection angle θ _1, and fan-shaped injection suitable for deodorization is achieved.

As described above, according to the present embodiment, the second outflow passage 21 having the same diameter along the axis G is formed at the boundary between the columnar upper portion 23b and the columnar lower portion 23a having different tip protruding positions. There is no reduced-diameter portion narrowed in the outflow direction, and the core in the outflow direction can be released from the second outflow path 21. Thereby, the wide nozzle hole conventionally provided as a separate part can be integrally formed with the button body 5. As a result, the number of parts and assembly man-hours can be reduced. Further, when jetting, the diffusion is restricted by the column lower portion 23a that is projected by a predetermined length L so that the lower injection range does not extend too much, and the projection length L of the column lower portion 23a is reduced. You can change the injection range theta ₂ of the lower design adjustment changing. In addition to this, by adjusting the design of the dimension from the tip surface 25a at the bottom of the column to the tip of the protruding piece 29, or the dimension from the tip surface 25b at the bottom of the column to the tip of the protruding piece 29, the vertical injection range Changes can be easily made. For example, when a deodorant is used as the contents, a rectangular spray pattern with a small lower injection angle θ ₂ can be obtained.

  Moreover, since the wall body 33 surrounding the upper side and both sides of the column body 23 is provided, the following advantages are obtained. For example, when the column body 23 is formed integrally with the button body 100, the column body 23 cannot be protruded from the button body 100 from the viewpoint of formability. For example, in this embodiment, the column body 23 is formed to be as short as 0.3 to 3.0 mm, but in that case, the user may accidentally push the button body 100 with a finger from the column body side, There is a possibility that the pillar body 23 and the protruding pieces 29a and 29b may be damaged by the finger. On the other hand, since the wall body 33 surrounding the periphery of the column body 23 is provided, even if the user accidentally pushes the button body 100 with a finger from the column body side, the wall body 33 or the column body 23 or The protruding piece 29 is protected and can be prevented from being damaged. Further, since the wall 33 surrounds the entire circumference of the column body 23, the distal end side of the aerosol button 100 can be easily visually recognized, so that an erroneous operation can be prevented. Furthermore, the fact that the wall 33 protrudes above the upper surface of the button main body 100 also contributes to preventing erroneous operation.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. For example, in the above embodiment, the wall 33 is formed in a rectangular shape, but the shape is not particularly limited as long as it surrounds the projecting pieces 29a, 29b and the column 23, and is circular, oval, rhombus, etc. Various shapes are possible. Further, from the viewpoint of preventing damage due to a user's malfunction, it is sufficient to surround at least the upper and both sides of the protruding pieces 29a and 29b and the column 33, and the wall may not be disposed below.

  Moreover, in the said embodiment, although the aerosol button 100 and the cap main body 1 are connected and formed integrally, these are manufactured separately and connected by another member like the hinge part 53 mentioned above. You can also.
