Japanese Unexamined Patent Publication No. 2017-013895

By the way, in the discharger of Patent Document 1, since the discharge hole is dew, the discharger must be separately covered with a protective cap or the like so that dust or the like does not adhere to the discharger. However, the protective cap needs to be removed and attached each time it is used, which is complicated. Especially with one hand, it is difficult to use.

Therefore, an object of the present invention is to provide a discharge member that can be easily used with one hand and an aerosol product using the discharge member.

The discharge member of the present invention covers the discharge nozzles 2, 21, 22 mounted on the aerosol valve 130 and the discharge nozzles 2, 21, 22 and operates the aerosol valve 130 via the discharge nozzles 2, 21, 22. The caps 3, 31, 32 are provided, and the operation caps 3, 31, 32 are slidable along the discharge nozzles 2, 21, 22. Before operating the aerosol valve 130, the discharge nozzles 2, 21 are provided. , 22 is provided with openings 3d and 32d for projecting the 22 to the outside.

Further, it is preferable that the periphery of the openings 3d and 32d is a scooping surface 3g and 32g for scooping out the discharged matter discharged from the discharge nozzles 2, 21 and 22 and adhering to the discharge nozzle. Further, it is preferable that the scooping surface 32g is formed by the tip of the brush 32b.

The discharge nozzles 2, 21, and 22 include an internal passage 2d extending in the axial direction, a closing portion 2e that closes the tip of the internal passage 2d, and a plurality of discharge holes 2f that open on the side of the internal passage 2d. Is also good. In this case, the inner peripheral surface of the discharge hole 2f may be provided with a pair of side surfaces 2g and 2h that control the discharge direction of the discharge material discharged from the internal passage 2d to the outside through the discharge hole 2f.

The aerosol product of the present invention is characterized by comprising an aerosol container 110, an effervescent content filled in the aerosol container 110, and any of the above-mentioned discharge members provided in the aerosol container 110.

In the discharge member of the present invention, since the discharge nozzle is covered with the operation cap, it is not necessary to separately attach a protective cap. Further, since the operation cap is provided with an opening for projecting the discharge nozzle to the outside, it can be used without removing the operation cap.

If the periphery of the opening is a rake face that is discharged from the discharge nozzle and scoops the discharge material adhering to the discharge nozzle, the discharge material is moved to the rake face when the operation cap returns to the original position. Can be made to.

If the rake face is composed of the tip of the brush, the ejected material adheres to the tip of the brush, so that it can be applied to the object as it is, which is convenient.

If the discharge nozzle has an internal passage extending in the axial direction, a closing portion that closes the tip of the internal passage, and a plurality of discharge holes that open on the sides of the internal passage, the discharged material has a complicated shape. A discharge with excellent design can be obtained.

If the inner peripheral surface of the discharge hole has a pair of side surfaces for controlling the discharge direction, the discharge direction of the discharge can be controlled. For example, the discharge is formed into a soft serve ice cream that swirls around the discharge nozzle. You can also do it.

It is a partial cross-sectional view which shows the aerosol product of this invention. 2A is a front view, FIG. 2B is a sectional view, and FIG. 2C is a plan view showing a discharge nozzle. 3A is a perspective view, FIG. 3B is a schematic view of a locking mechanism, and FIG. 3C is a front view showing a pushing operation, showing different aerosol products of the present invention. 4A is an end view and FIG. 4B is a cross-sectional view showing a state in which the contents are discharged, showing a further different aerosol product of the present invention.

Next, the aerosol product of the present invention will be described with reference to the drawings. As shown in FIG. 1, the aerosol product 100 of the present invention includes an aerosol container 110, an effervescent content filled in the aerosol container 110, and a discharge member 1 attached to the aerosol container 110.

The aerosol container 110 includes a container body 120, an aerosol valve 130 that switches between communication and non-communication between the inside and outside of the container body 120, and a mounting cup 140 that attaches the aerosol valve 130 to the opening of the container body 120. The container body 120 includes a cylindrical body portion 120a, a tapered shoulder portion 120b extending from the upper end of the body portion 120a, a cylindrical neck portion 120c extending from the upper end of the shoulder portion 120b, and a bead portion 120d at the upper end of the neck portion 120c. , A bottom portion (not shown) that closes the bottom of the body portion 120a. Further, a concave groove 120e continuous in the circumferential direction is formed between the bead portion 120d and the neck portion 120c. The aerosol valve 130 includes a stem 130a that discharges the contents, a stem rubber that switches between communication and non-communication between the stem hole of the stem 130a and the inside of the container body 120, a spring that urges the stem 130a upward, and a stem 130a. It is provided with a valve housing that accommodates the stem 130a so as to be movable up and down, and is known to open the stem hole by pushing down the stem 130a and close when the pushing down is stopped. The peripheral portion of the mounting cup 140 is engaged with the bead portion 120d of the container body 120.

Effervescent contents include skin care such as facial cleansers, cleaning agents, bathing agents, moisturizers, cleansing agents, sunscreens, lotions, shaving agents, depilatory agents, antiperspirants, bactericidal disinfectants, and pest repellents. Human products such as agents, shampoos, treatment agents, styling agents, hair dyes and other hair care agents, foods such as whipped cream, deodorants, fragrances, insect repellents, and household products such as bactericides. However, it is not limited to these uses.

This effervescent content comprises a stock solution containing the active ingredient for the above-mentioned use and a propellant for foaming the stock solution, and the propellant includes, for example, propane, butane, pentane and the like, which are aliphatic hydrocarbons having 3 to 5 carbon atoms. Examples thereof include liquefied gas such as hydrogen, hydrofluoroolefin and dimethyl ether, and compressed gas such as carbon dioxide gas and nitrogen. Among them, those containing surfactants such as fatty acid soap and solid oils such as higher alcohols and higher fatty acids in the undiluted solution because they have excellent foam formability and shape retention and it is easy to shape the foam into a desired shape. It is preferable to use liquefied gas as a propellant.

The discharge member 1 covers the discharge nozzle 2 mounted on the stem 130a of the aerosol valve 130 and the discharge nozzle 2, and is slidable along the axial direction of the discharge nozzle 2. The aerosol valve 130 is passed through the discharge nozzle 2. The operation cap 3 to be operated, the urging member 4 for returning the operation cap 3 to the original position before the operation, and the cover member 5 for covering the upper end of the aerosol container 110 are provided. However, it is not always necessary to provide the urging member 4 and the cover member 5.

The discharge nozzle 2 includes a mounting portion 2a mounted on the stem 130a, a nozzle portion 2b provided at the upper end of the mounting portion 2a, and a flange portion 2c protruding outward from between the mounting portion 2a and the nozzle portion 2b. It is roughly divided into. As shown in FIG. 2B, an internal passage 2d extending in the axial direction of the discharge nozzle 2 is provided from the mounting portion 2a to the nozzle portion 2b. The upper end of the internal passage 2d is closed by a closing portion 2e provided at the tip of the nozzle portion 2b. On the other hand, the nozzle portion 2b is provided with a plurality of discharge holes 2f that open on the side of the internal passage 2d. Therefore, the contents supplied from the stem 130a to the internal passage 2d are discharged to the outside from each discharge hole 2f.

To explain the discharge holes 2f in more detail, as shown in FIG. 2C, four discharge holes 2f are provided around the central axis of the nozzle portion 2b at substantially equal intervals. The inner peripheral surface of the discharge hole 2f includes a pair of side surfaces 2g and 2h that control the discharge direction of the discharge material discharged from the internal passage 2d to the outside through the discharge hole 2f. Specifically, the nozzle portion 2b is thick, and the inlet 2i of the discharge hole 2f (the boundary between the discharge hole 2f and the internal passage 2d) to the outlet 2j (the boundary between the discharge hole 2f and the outer surface of the nozzle portion 2b). A control passage CP having a length capable of controlling the discharge direction of bubbles, which are discharged substances, is formed by the pair of side surfaces 2g and 2h that continue to the above. For example, the horizontal length L1 of the control passage CP is longer than the horizontal width W1 of the inlet 2i of the discharge hole 2f. Further, the pair of side surfaces 2g and 2h form an arc from the internal passage 2d toward the outside, and each arc is curved in the same direction. In other words, the control passage CP is curved. The discharge direction of the discharged material can be controlled by changing the curvature and length of the pair of side surfaces 2g and 2h.

Returning to FIG. 1, the operation cap 3 has an appearance as if two cylinders having different diameters are stacked in the axial direction. The inside is hollow, and the inner diameter of the lower cylindrical body 3a is larger than the outer diameter of the cover member 5. Further, the inner diameter of the upper cylindrical body 3b is larger than the outer diameter of the flange portion 2c of the discharge nozzle 2. Further, an opening 3d for projecting the nozzle portion 2b of the discharge nozzle 2 to the outside (outside the operation cap 3) is provided at the center of the top plate 3c having a substantially circular shape in a plan view. Therefore, even if the operation cap 3 is pushed down downward, only the operation cap 3 can be pushed down for a certain distance without interfering with the discharge nozzle 2. When the operation cap 3 is pushed down to a certain distance, the top plate 3c that closes the upper end of the upper cylindrical body 3b comes into contact with the flange portion 2c of the discharge nozzle 2 so that the aerosol valve 130 can be operated via the discharge nozzle 2. (See the alternate long and short dash line in Fig. 1).

The urging member 4 is a coil spring. The upper end side of the urging member 4 extends downward from the ring-shaped second top plate 3e connecting the upper end of the lower cylindrical body 3a of the operation cap 3 and the lower end of the upper cylindrical body 3b. It is externally fitted to the cylindrical mounting portion 3f, and the lower end side is attached to the cover member 5. The cover member 5 has a substantially cylindrical shape and is attached to the container body 120 so as to cover the upper end of the container body 120. Specifically, the lower end of the cover member 5 is engaged with the concave groove 120e of the container body 120. Further, the arm portion 5a extends in the inner diameter direction from the inner peripheral side of the cover member 5. An annular receiving groove 5b in a plan view for receiving the urging member 4 is provided on the upper surface of the arm portion 5a.

The aerosol product 100 having the above configuration is in a state where the operation cap 3 covers the discharge nozzle 2 before use (before operation). In use, for example, a finger is placed on the second top plate 3e of the operation cap 3 and the operation cap 3 is pushed down downward. As described above, for a certain distance, only the operation cap 3 slides downward along the discharge nozzle 2 without interfering with the discharge nozzle 2. Therefore, before operating the aerosol valve 130, the discharge nozzle 2 (specifically, the discharge hole 2f of the nozzle portion 2) can be projected to the outside (projection operation). Then, when the top plate 3c of the operation cap 3 comes into contact with the flange portion 2c of the discharge nozzle 2, the discharge nozzle 2 is pushed down through the operation cap 3 and the aerosol valve 130 is opened (opening operation). When the aerosol valve 130 is opened, the contents are supplied from the aerosol container 110 into the discharge nozzle 2 through the stem 130a. The content goes upward through the internal passage 2d of the discharge nozzle 2, but is blocked by the closing portion 2e, so that the content is discharged to the outside from the discharge hole 2f opened to the side. At this time, since the contents are discharged to the outside through the curved control passage CP, the contents are discharged while swirling around the axis of the nozzle portion 2b. At the same time, because it moves upward due to the momentum of the propellant, the ejected material discharged later partially overlaps the contents (discharged material) discharged earlier, and the spiral (soft serve ice cream) discharged product. Is obtained. The contents gradually foam at the stage of being discharged from the aerosol container 110, and become foamy when discharged from the nozzle portion 2b to the outside.

When the pressing of the operation cap 3 is stopped, the aerosol valve 130 closes and the discharge of the contents is stopped. At the same time, the operation cap 3 moves upward due to the urging force of the urging member 4. At this time, the discharged material adhering to the periphery of the nozzle portion 2b is scooped from below by the top plate 3c of the operation cap 3. That is, the upper surface (top surface) of the top plate 3c located around the opening 3d of the operation cap 3 functions as a scooping surface 3g for scooping the discharged material. When the operation cap 3 returns to the original position before the protrusion operation, the discharge remains on the top surface of the operation cap 3, and the discharge nozzle 2 is covered with the operation cap 3 again.

In the aerosol product 100 having the above configuration, since the discharge nozzle 2 is covered by the operation cap 3 before the operation, it is not necessary to separately prepare a cap for protecting the discharge nozzle 2. Further, since the contents can be discharged with the operation cap 3 attached, it can be easily used with one hand. In particular, by simply pushing down the operation cap 3, a protrusion operation for projecting the discharge nozzle 2 from the operation cap 3 and an opening operation for opening the aerosol valve 130 can be performed. It is very convenient because the storage is done automatically. Further, since the top surface of the operation cap 3 substantially orthogonal to the axial direction of the discharge nozzle 2 scoops up the discharge material from the discharge nozzle 2, the shape of the discharge material (especially the shape on the outer peripheral side) is compared with the case of scooping by hand. It is hard to break and you can enjoy the shape of the ejected material for a long time. Further, even if a so-called after-draw occurs in which the contents remaining in the stem 130a are gradually discharged after a time even if the discharge operation is stopped, the discharge nozzle 2 is operated by the operation cap 3 unless the operation is performed. Because it is covered, it will not be exposed and can be kept looking good.

FIG. 3 shows another aerosol product 101. In the aerosol product 101, the discharge member 11 is provided with a lock mechanism LM for preventing erroneous operation of the operation cap 31. Note that FIG. 3A is a perspective view of the inside of the operation cap 31 so that the lock mechanism LM can be easily understood.

The lock mechanism LM is composed of a groove portion 31a provided on the inner peripheral surface of the operation cap 31, and a protrusion 51a protruding from the outer peripheral surface of the cover member 51 and fitted in the groove portion 31a of the operation cap 31. Specifically, the groove portion 31a is removed so as to extend horizontally from the lock section 31b, the operation section 31c extending upward from one end of the lock section 31b, and the other end of the lock section 31b to the lower end of the operation cap 31. It consists of a section 31d, and when the protrusion 51a is in the lock section 31b or the removal section 31d, the operation of the operation cap 31 is restricted, and the operation cap 31 is pushed down only when the protrusion 51a is in the operation section 31c. (See Fig. 3B). Four lock mechanisms LM are provided so as to be evenly spaced in the circumferential direction.

As described above, the aerosol product 101 having the above configuration includes the lock mechanism LM, so that erroneous operation can be prevented. Further, when the operation cap 31 is pulled up, the operation cap 31 does not rotate carelessly, so that the shape of the discharged material is not easily deformed. When the operation cap 31 is removed from the aerosol container 110, the protrusion 51a may be positioned in the removal section 31d and pulled up. When the protrusion 51a is not located in the removal section 31d, the operation cap 31 does not come off from the aerosol container 110, and it is possible to prevent the operation cap 31 from being accidentally removed.

In addition, in this aerosol product 101, the container body 121 does not have a neck portion 120c. Further, the operation cap 31 has a substantially dome shape, and the rake face 3g also has a substantially dome shape. Further, the flange portion 21c of the discharge nozzle 21 is also substantially dome-shaped according to the shape of the top plate of the operation cap 31. The cover member 51 has a substantially truncated cone shape. The urging member 4 such as a coil spring is not provided, but may be provided. The nozzle portion 21b is obtained by further adding a spiral twist to the nozzle portion 2b in FIG. 2, so that the discharged material can be more easily swiveled. Further, four discharge holes 2f are provided. Since other configurations are substantially the same as those of the above-mentioned aerosol product 100, the same reference numerals are given and detailed description thereof will be omitted.

FIG. 4 shows yet another aerosol product 102. In the aerosol product 102, the operation cap 32 of the discharge member 12 includes a brush 32b.

Specifically, the operation cap 32 includes a cylindrical base portion 32a whose upper end is closed and a brush 32b provided on the upper surface of the base portion 32a. The outer peripheral surface of the base portion 32a is provided with a recess 32c for hooking a finger during operation. Further, a vertical groove 32e extending in the vertical direction is provided on the inner peripheral surface. The vertical groove 32e is fitted with a projecting piece 52a provided on the outer peripheral surface of the cover member 52, so that the operation cap 32 carelessly rotates during operation (pushing down, pulling up). It functions as a rotation control mechanism RM that suppresses. The brush 32b is flocked on the upper surface of the base portion 32a, and the tips of the bristles are directed upward.

By the way, a through hole 32f is provided at the center of the upper surface of the base portion 32a having a substantially circular shape in a plan view. Then, before the operation, the discharge nozzle 22 protrudes from the through hole 32f. Therefore, the length of the nozzle portion 22b is longer than that of the discharge nozzle 2 in FIG. The brush 32b also has no bristles at the position corresponding to the through hole 32f, and forms an opening 32d through which the discharge nozzle 22 can be inserted. However, the tip of the brush 32b is located above the tip of the discharge nozzle 22 before the operation. Therefore, before the operation, the discharge nozzle 22 does not protrude to the outside and is covered by the brush 32b which is a part of the operation cap 32.

In the aerosol product 102, when the operation cap 32 is pushed down, the discharge nozzle 22 protrudes from the inside of the brush 32b through the opening 32d (protrusion operation). When the operation cap 32 is further pushed down, the top plate 3c of the base 32a comes into contact with the flange portion 2c of the discharge nozzle 22, and as a result of pushing down the stem 130a, the aerosol valve 130 opens and the contents are the discharge hole 2f of the discharge nozzle 22. Is discharged to the outside (opening operation). After that, if the operation cap 32 is pulled up, the discharged material B adhering to the outer periphery of the discharge nozzle 22 can be scooped up by the upper surface of the brush 32b, that is, the scooping surface 32g. The operation cap 32 is simply put on the aerosol container 110 and can be easily removed. Therefore, for example, the operation cap 32 can be removed from the aerosol container 110, and the discharge B can be applied to the object. In addition, the operation cap 32 can be easily cleaned. Since other configurations are substantially the same as those of the above-mentioned aerosol product 100, the same reference numerals are given and detailed description thereof will be omitted.

Although the typical embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. For example, the lock mechanism LM and the rotation regulation mechanism RM may be applied to the discharge member 1 of FIG. Further, the groove portion 31a corresponding to the operation section 31c of the lock mechanism LM and the vertical groove 32e of the rotation regulation mechanism RM do not have to be vertical, and may be inclined at an angle. Further, as the urging member 4, an elastic body such as rubber may be used in addition to the coil spring. The urging member 4 may be applied to the discharge member 12 of FIG. Further, although the discharge is scooped out by the top surface 3g of the operation caps 3, 31 and 32, it may be scooped out directly by hand. For example, if a hand or finger is placed on the top surface so as to surround the openings 3d and 32d and the operation caps 3, 31 and 32 are pushed down as they are, the contents are discharged onto the hand and finger.
