[0004] [Patent Document 1] Japanese Patent Publication No. 2022-027063 Summary of the Invention [Problem to be solved by the invention]

[0005] The inner and outer walls of the cap merely define a storage space for storing the extension tube wound in a circular shape.

[0006] The present invention provides a novel cap, an aerosol device equipped with the same, and an ejection method using the aerosol device. [Means for solving the problem]

[0007] A cap according to one aspect of the present invention is a cap connected to a spray unit of an aerosol device that sprays contents when the spray unit is pushed in one direction in a first direction and stops spraying the contents when the spray unit returns to the other direction in the first direction, and includes a base portion having a spray port, a connection portion provided on one side of the spray port of the base portion in the first direction and connectable to the spray unit of the aerosol device, and a substantially cylindrical peripheral wall extending from the base portion in the other direction in the first direction and arranged around the spray port. When the peripheral wall is pressed against a spray target from the one side in the first direction, the base portion and the peripheral wall, together with the spray target, define a spray space for the contents to be sprayed from the spray unit of the aerosol device through the spray port.

[0008] In the case of a cap according to one aspect of the present invention, the peripheral wall of the cap is pressed against the injection target from one side in the first direction, and the base portion and the peripheral wall, together with the injection target, define an injection space, thereby providing a novel cap that can inject contents into this injection space.

[0009] An aerosol device according to one aspect of the present invention comprises a device body and the cap. The device body comprises a container filled with contents and a spray unit attached to the container. The spray unit is configured to spray the contents when pushed in one direction in a first direction and to stop spraying the contents when pushed back in the other direction in the first direction. The cap is connected to the spray unit of the device body and is movable along the first direction together with the spray unit.

[0010] In the case of an aerosol device according to one aspect of the present invention, a novel aerosol device equipped with the above-described cap is obtained.

[0011] In one aspect of the present invention, an injection method involves pressing an approximately cylindrical peripheral wall, which extends from a base portion of a cap connected to an injection portion of an aerosol device in the other direction in a first direction and is arranged around the injection port of the base portion, against an injection target from one side in the first direction, thereby defining an injection space by the base portion, peripheral wall, and injection target, and the cap presses the injection portion of the aerosol device in one direction in the first direction, causing the contents to be injected from the injection portion through the injection port into the injection space.

[0012] In the spraying method according to one aspect of the present invention, the peripheral wall of the cap of the aerosol device is pressed against the target from one side in the first direction, thereby spraying the contents into the spray space defined by the base, the peripheral wall, and the target. In this way, a new spraying method is obtained. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, several embodiments of the present invention, including Example 1 and its design variations, will be described. Note that the components of the examples and design variations described below can be combined with each other as long as they are not inconsistent. Also, note that the materials, shapes, dimensions, numbers, and arrangements of the components in each aspect of the examples and design variations described below are merely examples, and that any design variation is possible as long as the same functions can be achieved. [Example]

[0015] Hereinafter, an aerosol device E according to a plurality of embodiments of the present invention, including Example 1 and its design variations, will be described with reference to Figures 1A to 4E. Figures 1A to 2 show the aerosol device E of Example 1. Figure 3 shows a first design variation of the aerosol device E of Example 1. Figures 4A to 4E show a second design variation of the aerosol device E of Example 1.

[0016] 1A, 1D, 1E, 4A, 4D, and 4E show the Z-Z' direction (first direction), which includes the Z direction (the other of the first directions) and the Z' direction (one of the first directions). 1A to 1C, 1E, 4A to 4C, and 4E show the X-X' direction (second direction). The X-X' direction is substantially perpendicular to the Z-Z' direction and includes the X direction (one of the second directions) and the X' direction (the other of the second directions). 1B to 1D and 4B to 4D show the Y-Y' direction (third direction). The Y-Y' direction is substantially perpendicular to the Z-Z' direction and the X-X' direction and includes the Y direction (one of the third directions) and the Y' direction (the other of the third directions).

[0017] The aerosol device E includes a device main body E1. The device main body E1 includes a container 100.

[0018] The container 100 may be a can (see FIGS. 1A to 3) or a resin container (not shown) that is filled with contents and a propellant (gas). The contents include a refrigerant or other chemicals.

[0019] The container 100 can be configured to have, for example, a cylindrical container body 110 with a bottom and an opening on the Z-direction side, and a lid 120 that closes the opening of the container body 110. The center of the lid 120 is provided with a cylindrical convex portion 121 with a top that protrudes toward the Z-direction side (see FIG. 1E). A hole 122 is provided in the center of the ceiling of this convex portion 121, penetrating the ceiling in the Z-Z' direction. Note that the convex portion 121 can be omitted. In this case, the hole 122 is provided in the center of the lid 120 (not shown).

[0020] The container 100 may further have a first guide portion 130 arranged around the ejection portion 200 (see FIG. 1E). The first guide portion 130 is a substantially cylindrical portion provided in the intermediate portion between the center portion and the outer peripheral edge portion of the lid 120, and extends in the Z-Z' direction. Note that the first guide portion 130 may be provided in the outer peripheral edge portion of the lid 120 instead of in the intermediate portion of the lid 120. Note that the first guide portion 130 may be omitted.

[0021] The container 100 may further include a second guide portion 140 disposed around the ejection portion 200 (see FIG. 1E). The second guide portion 140 includes a substantially cylindrical outer wall 141, a dome portion 142 that protrudes toward the Z direction, and a substantially cylindrical guide groove 143. The outer wall 141 is provided on the outer peripheral edge of the lid 120 and extends in the Z-Z′ direction. The dome portion 142 is provided on the inner side of the outer wall 141 of the lid 120. The guide groove 143 is formed between the dome portion 142 and the outer wall 141. In this case, the first guide portion 130 and the protrusion 121 are provided on the top of the dome portion 142. The second guide portion 140 may be omitted.

[0022] The device main body E1 further includes an ejection unit 200. The ejection unit 200 is attached to the container 100. The ejection unit 200 is configured to eject the contents in the container 100 when pushed in the Z' direction, and to stop ejecting the contents when returned to the Z direction.

[0023] For example, the spray unit 200 has a housing (not shown), a substantially cylindrical protrusion 210, a valve (not shown), and a spring. When the container 100 has the protrusion 121 (see FIG. 1E), the housing of the spray unit 200 is fixed to the protrusion 121 of the container 100 and is disposed within the container 100. When the container 100 does not have the protrusion 121 (not shown), the housing of the spray unit 200 is fixed to the surface of the lid 120 of the container 100 on the Z' direction side and is disposed within the container 100. A tube (not shown) for sucking up the contents within the container 100 is connected to the Z' direction side portion of the housing. The protrusion 210 is a substantially cylindrical member extending from the housing in the Z direction, protrudes in the Z direction from the hole 122 of the container 100, and is disposed outside the container 100. The protrusion 210 is in communication with the housing. The valve is accommodated within the housing so as to be movable in the Z-Z' direction. The spring is housed within the housing and biases the valve in the Z direction. The valve is biased in the Z direction by the spring, thereby closing the flow path that communicates with the protrusion 210 in the housing. When the protrusion 210 is pushed in the Z' direction against the biasing force of the spring, the valve opens the flow path, and the tube, flow path, and protrusion 210 become connected. With the valve opening the flow path, the propellant in the container 100 presses the contents, causing them to be sprayed in the Z direction through the tube, flow path, and protrusion 210. When the protrusion 210 is released from being pushed, the valve is biased by the spring and moves in the Z direction, closing the flow path. This stops the contents from being sprayed through the tube, flow path, and protrusion 210.

[0024] The aerosol device E further includes a cap 300 connected to the spray part 200 of the container 100. The cap 300 is preferably made of molded resin or the like, but may also be made of any material such as metal, carbon material, or wood.

[0025] The cap 300 has a base portion 310. The base portion 310 is a substantially disc-shaped (see FIGS. 1A to 3) or polygonal plate or block. The base portion 310 has a first surface 311 on the Z-direction side, a second surface 312 on the Z'-direction side, and an ejection port 313. The ejection port 313 may penetrate the center of the base portion 310 in the Z-Z' direction from the first surface 311 to the second surface 312, or may penetrate the center of the base portion 310 in the Z-Z' direction, which is thinner in the Z-Z' direction than the other portions of the base portion 310.

[0026] At least one substantially annular or polyannular rib 311a and / or at least one protrusion (not shown) may be formed on the first surface 311. In FIGS. 1B, 1E, and 2, two substantially annular ribs 311a are formed on the first surface 311. The two ribs 311a include an inner rib 311a and an outer rib 311a. The inner rib 311a is arranged around the injection port 313. The inner dimension of the inner rib 311a in a cross-sectional view taken along the X-X' and Y-Y' directions is larger than the inner dimension of the injection port 313 in a cross-sectional view taken along the X-X' and Y-Y' directions. The outer rib 311a is arranged at intervals around the inner rib 311a. The first surface 311 may be a flat surface without at least one rib 311a and at least one protrusion (see FIG. 3).

[0027] The cap 300 further includes a connecting portion 320. The connecting portion 320 is provided on the Z′ direction side of the ejection port 313 of the base portion 310. For example, the connecting portion 320 may be configured as a substantially cylinder (see FIG. 1E ) extending in the Z′ direction from the second surface 312 of the base portion 310 and opening in the Z′ direction, or may be configured as a substantially cylindrical hole (not shown) provided in the second surface 312 of the base portion 310 and opening in the Z′ direction. In either case, the interior of the connecting portion 320 communicates with the ejection port 313. The internal dimensions of the connecting portion 320 in a cross-sectional view taken along the X-X′ direction and the Y-Y′ direction are substantially the same as or larger than the internal dimensions of the protruding portion 210 of the ejection unit 200 of the device main body E1 in a cross-sectional view taken along the X-X′ direction and the Y-Y′ direction, and are larger than the internal dimensions of the ejection port 313 in a cross-sectional view taken along the X-X′ direction and the Y-Y′ direction. The protruding portion 210 of the spray part 200 of the device body E1 is fitted or inserted into the connecting portion 320, and the protruding portion 210 abuts against the peripheral edge of the spray port 313 of the base portion 310 from the Z' direction side. In this way, the connecting portion 320 is connected to the spray part 200 of the aerosol device E, and the cap 300 is movable along the Z-Z' direction together with the spray part 200.

[0028] The connecting portion 320 may have a plurality of arms extending in the Z' direction from the second surface 312 of the base portion 310, and the plurality of arms may be arranged at intervals in the circumferential direction of the ejection port 313 (not shown). In this case, the protruding portion 210 of the ejection unit 200 of the device main body E1 is inserted and held between the plurality of arms, and the protruding portion 210 abuts on the peripheral portion of the ejection port 313 of the base portion 310 from the Z' direction side, and the protruding portion 210 communicates with the ejection port 313.

[0029] The cap 300 further includes a peripheral wall 330. The peripheral wall 330 extends in the Z direction from the base portion 310 and is generally cylindrical (e.g., a generally triangular cylinder (not shown), a generally square cylinder (see FIGS. 4A to 4E), a generally pentagonal cylinder (not shown), a generally hexagonal cylinder (not shown), or a generally octagonal cylinder (not shown)). When the peripheral wall 330 is generally cylindrical, the inner and outer shapes of the peripheral wall 330 in cross-sections taken along the X-X' and Y-Y' directions may be generally circular or generally elliptical. When the peripheral wall 330 is generally polygonal, the inner and outer shapes of the peripheral wall 330 in cross-sections taken along the X-X' and Y-Y' directions may be generally regular polygons or generally irregular polygons.

[0030] The inner dimensions of the peripheral wall 330 in a cross-sectional view taken along the X-X' and Y-Y' directions are larger than the inner dimensions of the injection port 313 in a cross-sectional view taken along the X-X' and Y-Y' directions, and are smaller than or approximately equal to the outer dimensions of the base portion 310 in a cross-sectional view taken along the X-X' and Y-Y' directions. The portion of the base portion 310 located inside the peripheral wall 330 forms the bottom of the peripheral wall 330 on the Z'-direction side. The height of the peripheral wall 330 in the Z-Z' direction can be set arbitrarily, but may be approximately 2 to 30 mm or 4 to 30 mm. The thickness of the peripheral wall 330 can be set arbitrarily, but may be approximately 1 to 5 mm. When the peripheral wall 330 is substantially cylindrical, the diameter of the peripheral wall 330 can be set arbitrarily, but may be approximately 25 to 55 mm. When the peripheral wall 330 is a substantially polygonal tube, the dimensions of the peripheral wall 330 in the XX' direction and the YY' direction can be set arbitrarily, but can be set to 25 mm to 55 mm.

[0031] The peripheral wall 330 is a portion that is pressed from the Z' direction against a spray target (for example, a cloth personal item such as a towel or handkerchief that can be permeated with the contents). When the peripheral wall 330 is pressed against the spray target, the peripheral wall 330 and the base part 310, together with the spray target, define a spray space for the contents that are sprayed from the spray part 200 of the aerosol device E through the spray port 313.

[0032] As described above, the protrusion 210 of the spray part 200 is connected to the connection part 320 of the cap 300 and abuts against the peripheral part of the spray nozzle 313 of the base part 310 from the Z' direction side. Therefore, when the peripheral wall 330 is pressed against the spray target from the Z' direction side, the spray part 200 is pushed in the Z' direction by the cap 300, and the contents in the container 100 are sprayed from the spray part 200 into the spray space through the spray nozzle 313 of the base part 310.

[0033] It is preferable that the peripheral wall 330 is configured so that even if the contents are sprayed from the spray unit 200 into the spray space through the spray port 313 of the base unit 310 with the peripheral wall 330 pressed against the spray target from the Z' direction side, the contents do not leak from the peripheral wall 330. In other words, the peripheral wall 330 may be configured so that even if the contents are sprayed from the spray unit 200 into the spray space through the spray port 313 of the base unit 310 with the peripheral wall 330 pressed against the spray target from the Z' direction side, the contents do not leak from the peripheral wall 330.

[0034] For example, the peripheral wall 330 may not have through holes and notches. The through holes penetrate from the inner surface to the outer surface of the peripheral wall 330. That is, the through holes penetrate the peripheral wall 330 in a direction approximately perpendicular to the Z-Z' direction. The notches are similar to the through holes in that they penetrate from the inner surface to the outer surface of the peripheral wall 330, but are open in the Z direction. In this way, when the peripheral wall 330 does not have through holes and / or notches, even if the contents are injected from the injection unit 200 through the injection port 313 of the base unit 310 while the peripheral wall 330 is pressed against the injection target from the Z' direction, the contents will not leak from the through holes and / or notches in the peripheral wall 330. Note that the peripheral wall 330 may have through holes and notches.

[0035] The end face of the peripheral wall 330 on the Z direction side is a contact surface that comes into contact with the injection target. The contact surface of the peripheral wall 330 may be a flat surface, or may be convex in the Z direction.

[0036] It is preferable that the cap 300 does not have any part (for example, at least one of another peripheral wall, ridges, and protrusions) that is pressed against the injection target from the Z' direction side when the peripheral wall 330 is pressed against the injection target, but this is not limited to this.

[0037] When the container 100 is provided with the first guide portion 130, the cap 300 further includes a first guided portion 340. The first guided portion 340 extends in the Z direction from the base portion 310 and is disposed around the connecting portion 320. The first guided portion 340 is configured as a substantially cylindrical shape (see FIG. 1E) or multiple arms (not shown). When the first guided portion 340 is configured as a substantially cylindrical shape, the outer diameter of the first guided portion 340 is the same as or slightly smaller than the inner diameter of the first guide portion 130. The first guided portion 340 is guided within the first guide portion 130 so as to be movable in the Z-Z′ direction. When the first guided portion 340 is configured as multiple arms, the multiple arms are disposed in a ring shape around the connecting portion 320 and are guided within the first guide portion 130 so as to be movable in the Z-Z′ direction. Note that when the first guide portion 130 is omitted, the first guided portion 340 is also omitted.

[0038] When the container 100 is provided with the second guide portion 140, the cap 300 further includes a second guided portion 350. The second guided portion 350 is a substantially cylindrical shape extending in the Z direction from the base portion 310 and is disposed around the first guide portion 130. The outer diameter of the second guided portion 350 is the same as or slightly smaller than the inner diameter of the outer wall 141 of the second guide portion 140. The inner diameter of the second guided portion 350 is the same as or slightly smaller than the outer diameter of the dome portion 142 of the second guide portion 140. The second guided portion 350 is inserted into the guide groove 143 of the second guide portion 140 and is guided movably in the Z-Z′ direction between the outer wall 141 and the dome portion 142 of the second guide portion 140. Note that when the second guide portion 140 is omitted, the second guided portion 350 is also omitted.

[0039] A method for connecting the cap 300 to the spray unit 200 of the device body E1 of the aerosol device E described above will be described in detail below. First, the device body E1 and the cap 300 are prepared. Then, in the Z-Z' direction, the spray unit 200 of the device body E1 is brought relatively close to the connection unit 320 of the cap 300, and the protrusion 210 of the spray unit 200 is fitted or inserted into the connection unit 320, and the protrusion 210 of the spray unit 200 is brought into contact with the peripheral portion of the nozzle 313 of the base unit 310. In this manner, the cap 300 is connected to the spray unit 200 of the device body E1.

[0040] When the container 100 is provided with a first guide portion 130 and the cap 300 is provided with a first guided portion 340, when the injection portion 200 of the device main body E1 is brought relatively close to the connection portion 320 of the cap 300, the first guided portion 340 is guided so as to be freely movable in the Z-Z' direction within the first guide portion 130.

[0041] When the container 100 is provided with a second guide portion 140 and the cap 300 is provided with a second guided portion 350, when the injection portion 200 of the device main body E1 is brought relatively close to the connection portion 320 of the cap 300, the second guided portion 350 is guided so as to be freely movable in the Z-Z' direction within the guide groove 143 of the second guide portion 140.

[0042] Hereinafter, an injection method for injecting contents onto an injection target using the above-described aerosol device E will be described. The container 100 of the aerosol device E is grasped, and the cap 300 is directed toward the injection target. Then, the peripheral wall 330 of the cap 300 is pressed against the injection target from the Z' direction side. In this state, the peripheral wall 330 and the base portion 310, together with the injection target, define an injection space for the contents to be injected from the injection unit 200 of the aerosol device E through the injection port 313. By pressing the peripheral wall 330 of the cap 300 against the injection target from the Z' direction side, the injection unit 200 is pushed in the Z' direction via the cap 300, and the contents in the container 100 are injected from the injection unit 200 into the injection space through the injection port 313 of the base portion 310.

[0043] In addition, when cap 300 is configured so that the contents do not leak from peripheral wall 330 even when the contents are injected from spray unit 200 into the injection space through injection port 313 of base unit 310 with peripheral wall 330 pressed against the injection target from the Z' direction side, the above injection method is configured to exclude the contents injected into the injection space leaking from peripheral wall 330 when peripheral wall 330 of cap 300 is pressed against the injection target. In a state in which peripheral wall 330 of cap 300 is pressed against the injection target from the Z' direction side, when peripheral wall 330 of cap 300 does not have a portion on the inside of peripheral wall 330 that is pressed against the injection target from the Z' direction side, the above injection method is configured to exclude the presence of something on the inside of peripheral wall 330 that is pressed against the injection target when peripheral wall 330 of cap 300 is pressed against the injection target.

[0044] Here, we will explain aerosol device EX, an experimental example simulating aerosol device E, and aerosol device EC, a comparative example for comparison. As shown in FIG. 6, aerosol device EC has the same configuration as aerosol device E of Example 1, except that cap 300′ does not have a peripheral wall 330. Two approximately annular ribs 311a are formed on a first surface 311 of cap 300′ of aerosol device EC. The container 100 of aerosol device EC is a can with an outer diameter of 45 mm. The outer diameter of base portion 310 of cap 300′ of aerosol device EC is 32 mm. The outer and inner diameters of outer ribs 311a of cap 300′ are 27.5 mm and 18 mm, respectively. The outer and inner diameters of inner ribs 311a of cap 300′ are 13 mm and 9 mm, respectively. The height of the two ribs 311a is 2 mm. On the other hand, as shown in Fig. 5, the aerosol device EX has the same configuration as the aerosol device EC, except that a peripheral wall 330 made of cardboard is placed on the base part 310 of the aerosol device EC. The peripheral wall 330 has an outer diameter of approximately 31 mm, an inner diameter of approximately 30 mm, and a dimension in the Z-Z' direction of 17 mm. Fig. 7 is an enlarged view of a target onto which the cap of the aerosol device of the experimental example is pressed and the contents are sprayed from the aerosol device. Fig. 8 is an enlarged view of a target onto which the cap of the aerosol device of the comparative example is pressed and the contents are sprayed from the aerosol device.

[0045] When the container 100 of the aerosol device EC is grasped and the cap 300' is directed toward the target (a towel) and pressed against the target from the Z' direction, the two ribs 311a of the cap 300' are pressed against the target from the Z' direction. As a result, the spray unit 200 is pressed in the Z' direction via the cap 300', and the content (coolant) in the container 100 is sprayed from the spray unit 200 through the nozzle 313 of the base unit 310 onto the target, freezing the sprayed portion of the target. However, as shown by the arrows in FIG. 8 , the content sprayed onto the target leaks out, over the two ribs 311a, from between the target and the two ribs 311a. In the aerosol device EC, the two protrusions 311a are pressed against the target to be sprayed, so the contact area is large, and it is thought that this is because when the two protrusions 311a are pressed against the target to be sprayed, the gap that occurs between the two protrusions 311a and the target to be sprayed tends to become large.

[0046] On the other hand, when the aerosol device EX is grasped, the cap 300 is directed toward the target (towel) and pressed against the target from the Z' direction, the peripheral wall 330 of the cap 300 is pressed against the target from the Z' direction. In this state, the peripheral wall 330 and the base portion 310, together with the target, define an injection space for the contents (coolant) to be injected from the injection unit 200 of the aerosol device EX through the injection port 313. By pressing the peripheral wall 330 of the cap 300 against the target from the Z' direction, the injection unit 200 is pushed in the Z' direction via the cap 300, and the contents in the container 100 are injected from the injection unit 200 into the injection space through the injection port 313 of the base portion 310. As a result, the contents freeze the portion of the injection space of the target. As shown in FIG. 7, it was found that the injected contents are unlikely to leak out from between the peripheral wall 330 and the target, beyond the peripheral wall 330. In aerosol device EX, only peripheral wall 330 is pressed against the target to be sprayed (i.e., there is no part inside peripheral wall 330 that is pressed against the target to be sprayed), so the contact area is small, and it is presumed that this is because the gap that occurs between peripheral wall 330 and the target to be sprayed is smaller than the gap that occurs between the two protrusions 311a of aerosol device EC and the target to be sprayed.

[0047] As described above, there have been obtained a novel cap 300 capable of injecting contents into an injection space, an aerosol device E equipped with the cap, and an injection method using the aerosol device E. The object to be injected is not limited to cloth personal items, and can be changed as appropriate depending on the contents to be injected. [Explanation of symbols]
