  By the way, the discharge member of Patent Document 1 is mainly for discharging a foam, and cannot be applied to a member for discharging a mist. Although the discharge member disclosed in Patent Document 2 discharges a mist, the mist is simply ejected from a nozzle, and there is no idea that the mist forms something.

  Therefore, an object of the present invention is to provide a discharge member capable of forming a vortex ring with a mist sprayed from an aerosol container.

  The discharge member of the present invention is a discharge member attached to the aerosol container 2, and is a storage space S for storing the mist sprayed from the aerosol container 2, and for discharging the mist to the outside of the storage space S. A storage member 11 having a discharge hole 11a, and an extruding means P for extruding a mist from the storage space S through the discharge hole 11a, wherein the discharge hole 11a is substantially circular and has a smaller diameter than the storage space S. It is characterized by being.

  In addition, it is preferable that the ejection hole 14a for ejecting the atomized material into the storage space S and the ejection hole 11a are provided at shifted positions. Further, it is preferable that the pushing means P is constituted by a pushing member 12 inserted into the storage member 11 and a spring 13 for urging the pushing member 12 toward the discharge hole 11a.

  A cam mechanism C that rotates the storage member 11 relatively to the pushing member 12 to press the pushing member 12 against the urging force of the spring 13 and further rotates the pushing member 12 to suddenly release the pushing. Is preferably composed of a storage member 11 and an extruding member 12.

  Specifically, the cam mechanism C includes a guide groove 11b provided on the inner surface of the storage member 11 and a protrusion 12d provided on the outer surface of the push-out member 12 and sliding along the guide groove 11b. However, it is preferable to include an inclined portion 11b1 for pressing the pushing member 12 against the urging force of the spring 13, and an opening portion 11b2 for rapidly releasing the pressing.

  It is preferable that the spraying operation of the aerosol container 2 is performed with the pressing of the pushing member 12.

  The aerosol product of the present invention includes the ejection member 10 described in any of the above, an aerosol container 2 equipped with the ejection member 10, and contents filled in the aerosol container 2.

  In the discharge member of the present invention, the mist sprayed from the aerosol container can be stored in the storage space, and the discharge hole for discharging the mist from the storage space is substantially circular. Since the diameter of the mist is also small, the mist is pushed out of the storage space from the discharge hole by the pushing means, so that the mist is discharged in a vortex ring (ring shape).

  When the injection hole and the discharge hole that inject into the storage space are provided at positions shifted from each other, it is easy to store the mist in the storage space and easily form a swirl ring that is clearly visible. Further, if the pushing means is constituted by a pushing member inserted into the storage member and a spring for biasing the pushing member toward the discharge hole, the mist can be vigorously discharged by the spring, Easy to make swirl ring. Further, even if the pressure of the contents in the aerosol container is low, the contents (fog) can be delivered to the distance by the vortex ring.

  In addition, a cam mechanism that presses the pushing member against the urging force of the spring by rotating the storing member relative to the pushing member and suddenly releases the pressing by further rotating the storing member, If it is constituted by the pushing member, the vortex ring can be discharged only by rotating the storage member.

  In particular, the cam mechanism includes a guide groove provided on the inner surface of the storage member and a projection provided on the outer surface of the push member and sliding along the guide groove. The guide groove resists the pushing member against the urging force of the spring. By providing an inclined portion for pressing the pressing member and an opening portion for suddenly releasing the pressing, the movement of the pushing member is stabilized, and the vortex ring can be stably formed.

  If the spraying operation of the aerosol container is performed with the pushing of the pushing member, the supply of the mist to the storage space and the discharge of the supplied mist can be performed by a series of operations. When the aerosol container has a metering valve, the size of the vortex ring, the momentum to be discharged, and the diffusion state are easily stabilized.

It is sectional drawing of the aerosol product which shows a series of states when rotating a storage member. FIG. 3 is a cross-sectional view illustrating an aerosol product according to another embodiment of the present invention. 5A is a schematic diagram of a metering valve, FIG. 5A illustrates a state before an injection operation, and FIG. 5B illustrates a state during an injection operation.

  As shown in FIG. 1, the discharge member 10 of the present invention is used by being attached to an aerosol container 2, and includes a storage space S for storing a mist sprayed from the aerosol container 2, It has a storage member 11 having a discharge hole 11a for discharging the body out of the storage space S, and an extruding means P for pushing out the mist from the storage space S through the discharge hole 11a.

  The pushing means P includes a pushing member 12 inserted into the storage member 11, and a spring 13 for urging the pushing member 12 toward the discharge hole 11a.

  The ejection member 10 includes a cam mechanism C. Specifically, while the storage member 11 is rotated relatively to the pushing member 12, the pushing member 12 is pressed against the urging force of the spring 13, and the pressing is suddenly released by further rotating. The cam mechanism C includes a storage member 11 and a pushing member 12.

  In addition, the discharge member 10 includes a button 14 for spraying the contents in the aerosol container 2 in a mist state, and a guide member 15 for guiding the rotation of the storage member 11. Then, the aerosol product 1 is configured by attaching the ejection member 10 to the aerosol container 2 filled with contents. Hereinafter, each component will be described in detail.

  The aerosol container 2 includes a bottomed cylindrical container body 3 having an opening at an upper end, and a valve assembly 4 attached to close the opening of the container body 3. The valve assembly 4 includes a valve mechanism B that communicates / blocks the inside and outside of the container body 3 and a mounting cup 4b for attaching the valve mechanism B to the container body 3. The valve mechanism B includes a stem 4a, a stem rubber, a housing that holds the stem 4a and the stem rubber, and a spring that urges the stem 4a upward to maintain closing by the stem rubber. The valve mechanism B is opened by pushing down the stem 4a, so that the contents in the aerosol container 2 can be ejected. In this embodiment, the container body 3 and the mounting cup 4b are made of metal, and a bead portion 5 is formed at an engaging portion between the container body 3 and the mounting cup 4b. However, it may be made of resin.

  The contents filled in the aerosol container 2 are a propellant and a stock solution. Examples of the propellant include a liquefied gas such as an aliphatic hydrocarbon having 3 to 5 carbon atoms such as propane, butane, and pentane, a hydrofluoroolefin, and dimethyl ether; a carbon dioxide gas; and a compressed gas such as nitrogen. It is preferable to use a liquefied gas because it is easy to form a mist and easily form a vortex ring. The undiluted solution includes, for example, an active ingredient for space such as a deodorant, a fragrance, an insecticide, an insect repellent, a bactericide, and a solvent such as alcohol such as ethanol, water, and an oil such as hydrocarbon oil. No. In particular, those containing 40 to 95% by mass of the liquefied gas in the contents are preferable, and the vortex ring can be easily delivered to a distant place. Further, the pressure of the liquefied gas is preferably as low as 0.1 to 0.4 MPa (25 ° C.). This is because the atomized material easily stays in the storage space S, and the accumulated atomized atom easily forms a vortex ring by the pushing means P and is easily delivered to a distant place. However, the present invention is not limited to these, and any material can be used as long as it becomes a mist when injected.

  The storage member 11 has a substantially cylindrical shape having an upper bottom. A part of the substantially columnar space inside the storage member 11 is a storage space S. The discharge hole 11a is provided at the center of the upper bottom. The discharge hole 11a is substantially circular in a plan view, and has a smaller diameter than the outer diameter of the storage space S (that is, the inner diameter of the storage member 11). Specifically, the diameter of the discharge hole 11a is set to １ ／ to ／ of the inner diameter of the storage space S. In this state, it can be said that an edge is provided around the discharge hole 11a, and the exit from the storage space S is narrowed by the edge.

  On the inner surface of the storage member 11, a guide groove 11b constituting a part of the cam mechanism C is provided. The guide groove 11b is formed by partially reducing the thickness of the storage member 11, and has a substantially saw-tooth shape in a side view. Specifically, as shown in FIGS. 1 and 2, an inclined portion 11b1 for pressing the pushing member 12 against the urging force of the spring 13 and an opening portion 11b2 for suddenly releasing the pressing are provided. Have. The opening 11b2 is provided in parallel with the biasing direction of the spring 13. Specifically, it is provided in parallel with the central axis of the storage member 11. The guide groove 11b has a horizontal portion connecting the inclined portion 11b1 and the open portion 11b2. The horizontal portion maintains the pressing of the pushing member 12 by the inclined portion 11b1 (hereinafter, a first horizontal portion 11b3) and the horizontal portion maintains the state in which the pressing by the inclined portion 11b1 is released (hereinafter, a second horizontal portion). 11b4). The guide groove 11b is continuous in the circumferential direction, and a plurality of these inclined portions 11b1, open portions 11b2, first horizontal portions 11b3, and second horizontal portions 11b4 are provided. However, only one of each may be provided.

  The pushing member 12 is substantially cylindrical with an upper bottom. The substantially cylindrical space provided at the center (inside) is an insertion hole 12a for inserting (accommodating) the button 14. The upper bottom (top surface) is an extruding portion 12b for compressing the storage space S. A communication hole 12b1 that communicates with an injection hole 14a of the button 14, which will be described later, is provided at the center of the pushing portion 12b. A mounting portion 12c for mounting the spring 13 is provided below the pushing portion 12b. The outer diameter of the pushing portion 12b is slightly smaller than the inner diameter of the storage member 11 (the inner diameter of the portion where the guide groove 11b is not provided). Therefore, the pushing member 12 can move up and down in the storage member 11 without resistance. A protrusion 12d that constitutes a part of the cam mechanism C is provided on the outer periphery of the pushing portion 12b. The cam mechanism C includes a guide groove 11b and a protrusion 12d. The protrusion 12d has, for example, a substantially triangular shape in a side view having a surface parallel to the inclined portion 11b1 so as to easily slide along the guide groove 11b (particularly, the inclined portion 11b1) (see FIG. 2). The outer diameter of the mounting portion 12c is smaller than the outer diameter of the pushing portion 12b. The spring 13 is fitted around the outer periphery of the mounting portion 12c.

  As the spring 13, for example, a coil spring is used. However, as long as the pushing member 12 can be urged toward the discharge hole 12a, various known springs such as a leaf spring and an air spring can be employed. The lower end of the spring 13 is in contact with the upper surface of the mounting cup 4b. The biasing direction of the spring 13 is parallel to the central axis of the storage member 11.

  The button 14 is attached to the stem 4a. The button 14 has a substantially columnar shape, and is provided with an ejection hole 14a for ejecting contents at the center of the upper end. A mechanical break-up mechanism 14b for ejecting the contents supplied from the aerosol container 2 in a mist state is provided downstream of the ejection holes 14a. The button 14 includes a flange portion 14c that extends outward in a radial direction at a lower portion. The outer diameter of the flange portion 14c is larger than the diameter of the insertion hole 12a. Therefore, when the pushing member 12 is lowered, the upper surface of the flange portion 14c comes into contact with the lower end of the pushing member 12 (the mounting portion 12c). At this time, the uppermost surface of the button 14 and the lower surface of the upper bottom of the pushing member 12 may abut.

  The guide member 15 has a substantially cylindrical shape, and includes a cover part 15a that covers the upper part of the container body 3 and a rising part 15b that rises from the cover part 15a and includes the lower part of the storage member 11. A locking portion 15c that protrudes radially inward from the inner surface of the cover portion 15a is provided, and the locking portion 15c is engaged with a groove below the bead portion 5. A jaw 15d protruding radially inward from below the rising portion 15b is provided so that the storage member 11 can be placed thereon. The lower surface of the jaw portion 15d is in contact with the bead portion 5 so as to sandwich the bead portion 5 with the locking portion 15c. Note that the guide member 15 does not necessarily need to be provided.

  When the ejection member 10 having the above configuration is not used, the protrusion 12d is located at the second horizontal portion 11b4 (standby position: see S1 in FIG. 3). Even when not in use, a storage space S having a capacity of C1 is formed between the inside of the storage member 11 and the upper surface of the push-out member 12.

  The discharge operation is performed by rotating the storage member 11 around the axis of the storage member 11. When the storage member 11 is rotated, the protrusion 12d gradually moves downward along the inclined portion 11b1, as shown in S2 of FIG. That is, the pushing member 12 is pressed downward against the urging force of the spring 13. At this time, the capacity of the storage space S gradually increases as the pushing member 12 descends.

  When the projection 12d comes near the end point of the inclined portion 11b1 (boundary with the first horizontal portion 11b3), the lower end of the pushing member 12 comes into contact with the upper surface of the flange portion 14c of the button 14, and the stem 4a is pushed down, so that the aerosol container is pushed down. 2 discharges the contents. That is, the injection operation of the aerosol container 2 is performed. The discharged content is injected into the storage space S from the injection hole 14a through the button 14, and at this time, it drifts in the storage space S as a mist. In this state, the capacity of the storage space S becomes the maximum (C2). The discharge of the contents continues as long as the projection 12d is kept at the first horizontal portion 11b3 (see S3 in FIG. 3). When the storage member 11 is further rotated, the protrusion 12d passes over the first horizontal portion 11b3. That is, the protrusion 12d reaches the opening 11b2, and the pressing of the pushing member 12 by the guide groove 11b is suddenly released. At this time, the extruding member 12 moves toward the discharge hole 12a so as to be repelled by the compressed spring 13. Then, the capacity of the storage space S rapidly decreases (returns from the capacity C2 to the capacity C1), and the mist floating in the storage space S is discharged to the outside of the storage space S through the discharge holes 11a. . The mist that has been vigorously discharged becomes a ring shape that spirals from the inside to the outside (forms a vortex ring: see S4 in FIG. 3). The ratio (C1 / C2) of the volume C1 when the content is rapidly compressed and reduced by the pushing member 12 to the volume C2 when the content is injected from the injection hole 14a is 0.8 to 0.95. Is preferred.

  When the projection 12d passes through the opening 11b2, the pushing member 12 returns to the standby position. Accordingly, the pushing down of the button 14 by the pushing member 12 is also released, and the discharge of the contents is stopped. This completes one ejection operation. Since the guide groove 11b is provided continuously on the inner surface of the storage member 11, if the storage member 11 is rotated, the above process is repeated.

  FIG. 4 is a cross-sectional view illustrating an aerosol product according to another embodiment of the present invention. In this aerosol product 1A, a fixed quantity valve B1 that can inject a fixed amount by a single discharge operation is used as the valve mechanism B. As shown in FIG. 5A, when the protrusion 12d of the pushing member 12 is located at the second horizontal portion 11b4, the inside of the housing 4e and the inside of the container body 3 are in communication with each other. When 12d is located in the first horizontal portion 11b3, the blockage of the stem hole 4a1 by the stem rubber 4c is released (the stem hole 4a1 communicates with the inside of the housing 4e) and the lower end of the stem 4a is inserted into the housing 4e. The one in which the supply of the content is shut off is used, and a fixed amount of the content can be injected into the storage space S without being affected by the rotation speed of the pushing member 12. Further, the pushed-down stem 4a returns to the original position by the spring 4d, so that a fixed amount of contents can be ejected every time a discharging operation is performed. In addition, it is preferable that the injection amount to be injected is 0.01 to 1 ml.

  Further, in the aerosol product 1A, the injection hole 14a and the discharge hole 11a are provided at shifted positions. Specifically, the discharge hole 11a is provided at a position deviated from the central axis of the storage member 11, and the central axis of the discharge hole 11a is deviated from the central axis of the injection hole 14a. In other words, the ejection hole 11a is not located on the central axis of the ejection hole 14a, and the ejection hole 11a is provided at a position shifted from the ejection direction of the mist. In this case, the mist is easily retained in the storage space S, and the vortex ring is easily formed by the pushing member 12. Other configurations are the same as those of the aerosol product 1 shown in FIG. 1, and therefore, are denoted by the same reference numerals, and detailed description is omitted.

  As described above, the representative embodiment of the present invention has been described, but the present invention is not limited to the above embodiment, and can be variously modified and implemented within the scope of the present invention. For example, in the above embodiment, the height positions of the plurality of first horizontal portions 11b3 are aligned, but may be different. Specifically, the height position of some of the first horizontal portions 11b3 may be set to a position where the spray operation of the aerosol container 2 is not performed. Even in this case, if the mist remains in the storage space S, the vortex ring can be released. Further, the mist that remains in the storage space S can be effectively used. Further, both or one of the first horizontal portion 11b3 and the second horizontal portion 11b4 may be omitted. Even in this case, the cam mechanism C is established. Part of the configuration between different embodiments can be appropriately diverted. For example, the metering valve B1 may be used for the aerosol product 1 in FIG. 1, or the discharge holes 11a may be provided in a shifted manner. Further, in the aerosol product 1A of FIG. 4, the discharge hole 11a may be provided at the center. The number of the protrusions 12d may be one or more. When a plurality of projections 12d are provided, they may be provided at equal intervals in the circumferential direction on the outer periphery of the pushing member 12. Further, the protrusion 12 d may be provided on the storage member 11, and the guide groove 11 b may be provided on the pushing member 12. A retaining mechanism for the storage member 11 may be provided between the storage member 11 and the guide member 15, the mechanism including a groove that is continuous in the circumferential direction and a protruding piece that engages with the groove. In this case, the storage member 11 is prevented from falling out of the guide member 15 while allowing the storage member 11 to rotate in the circumferential direction.
