JP 2001-180773 A JP 2002-12276 A JP 2000-177786 A Japanese Patent Laid-Open No. 9-40045 JP 2002-2838 A JP 2000-191062 A JP 2002-53187 A JP 2000-191060 A JP 2002-193362 A JP 2001-301853 A JP 2003-12061 A JP 2001-31158 A

An aerosol container consists of a pressure-resistant container and an aerosol valve attached to the opening of the container, and a propellant such as a stock solution containing active ingredients as contents in the container and a flammable liquefied gas such as liquefied petroleum gas or dimethyl ether. In addition, an aerosol product is obtained by mounting an injection member.
The aerosol product has a pressure of about 0.2 to 0.6 MPa at room temperature, and when the valve is opened by an injection operation such as pushing down the injection member, the aerosol composition inside the container is injected outside.

  Currently, aerosol products that are no longer needed are collected as non-combustible garbage by consumers with no aerosol composition remaining in the container (empty state). There is an accident that causes a fire because the aerosol product is compressed in the collection vehicle and the container ruptures. Aerosol products are provided with a cautionary note or label to dispose of them after they have been used up, but they may still be disposed of with the aerosol composition remaining inside the container, which can easily cause a fire accident. ing.

  However, it is troublesome for the consumer to perform the injection operation until the inside of the container is emptied independently of the purpose of use. In particular, many aerosol products perform the injection operation by pushing down the push button of the injection member with a finger. However, it is necessary to continue to press the injection member until the injection is completed, which is troublesome.

  As a means for facilitating the discharge of the aerosol composition remaining in the aerosol container, for example, a discharge mechanism that removes a push button, attaches a discharge tool directly to the valve, and keeps the valve open at all times. Is known (see Patent Documents 1, 2, 3, and 4). And it is what has such a mechanism, and the patent document 1 is disclosing what the above-mentioned discharge device is attached to the cap of an aerosol product so that normal use of an aerosol product may not be disturbed, Patent Document 3 discloses that the cap of Patent Document 1 is attached to the bottom of the pressure vessel. Japanese Patent Application Laid-Open No. 2004-228688 discloses a technique in which a push button is removed, the push button is inverted and mounted inside a cap, and the cap is mounted on a cover member to open the valve.

  There is also known a discharge mechanism in which a discharge tool is attached while an injection member such as a push button is attached, and the valve is always open. In Patent Document 5, a protrusion for pressing the push button on the top surface of the cap and an engagement protrusion for mounting the cap on the cover member are provided, and the cap is inverted and the upper surface of the cap is attached to the cover member. Thus, it is disclosed that the push button is depressed and the valve is always opened. Further, Patent Documents 6 and 7 disclose that a part of the top surface of the cap is bent or attached to the container in a pressed down state, whereby the push button is pressed down to always open the valve.

  Furthermore, a discharge mechanism is known in which a push button and a cover member or a cap are used to keep the valve open at all times. Patent Document 8 discloses a structure in which a rotating protrusion attached to a push button is raised upward and a cap is attached to a container so that the rotating protrusion comes into contact with the top surface of the cap and the push button is pushed down. Yes. Patent Document 9 discloses a device that rotates a push button to engage a protrusion of the push button with a cover member, and holds the push button in a depressed position. Japanese Patent Application Laid-Open No. H10-228561 discloses a device in which the lever at the rear part of the push button is picked and turned in a state where the push button is depressed, and the lever is engaged with the groove of the cover member. Japanese Patent Application Laid-Open No. H11-228561 discloses a mechanism in which a rotary lever is engaged with a cover member by rotating a rotary lever at the rear of the push button after the push button is pressed down.

  And patent document 12 is an injection member which consists of a push button and a cover member, and after pushing down a push button, a button is always pushed down by putting a flat plate between the upper surface of a push button and a cover member. What you can do is disclosed.

  The present invention is an injection member composed of a push button and a cover member, and an aerosol capable of reliably discharging the entire amount of the aerosol composition remaining in the aerosol container by a simple method using coins such as coins It aims at providing the injection member for products.

An aerosol product injection member according to the present invention is an injection member that is attached to an aerosol container having an aerosol valve secured to an opening of a pressure-resistant container, and is attached to the stem of the aerosol valve and is movable up and down, and an aerosol A cover member attached to the head of the container, the push button has an injection hole on the front, the cover member is attached to the aerosol container, and extends upward from the attachment part, A pair of side wall portions covering both side surfaces of the push button are formed, and projecting portions projecting inwardly are formed on the inner surfaces of the respective side wall portions, and the lower surface of the projecting portion is substantially the same height as the upper surface of the push button. It is configured to become, diameter 20~30mm between the upper surface of the push button and the protrusion, by inserting a disc-shaped coins having a thickness of 1 to 3 mm, opening the aerosol valve And the front between the pair of side walls is opened so that the aerosol composition injected from the injection hole passes, and the rear between the pair of side walls presses down the push button. It is characterized in that it is opened so that the inserted coin can be inserted and the inserted coin can be pulled out backward (Claim 1).

In such an injection member, it is preferable that the cover member has a locking portion that locks the tip of the coin when the coin is inserted between the protruding portion and the upper surface of the push button. Moreover, it is preferable that the lower surface of the protrusion is parallel to the upper surface of the push button.

The aerosol product injection member of the present invention is configured such that a protruding portion protruding inward is formed on the inner surface of each side wall portion, and the lower surface of the protruding portion is substantially the same height as the upper surface of the push button. Since the aerosol valve is held in the open position by inserting a coin between the protrusion and the upper surface of the push button, the aerosol valve can be opened by using a coin such as a coin used in daily life. It is easy to discharge the contents after using the aerosol product. This facilitates disposal of the aerosol product.
Further, the front between the pair of side walls is opened so that the aerosol composition injected from the injection hole passes, and the rear between the pair of side walls is a finger for pressing down the push button. Since it is opened so that it can be inserted and the inserted coin can be pulled out backward, it is easy to pull out the coin after the contents are discharged, and it is easy to discard the aerosol product.
Since the coin has a diameter of 20 to 30 mm and a thickness of 1 to 3 mm, it is not necessary to provide a coin as an accessory to the aerosol product in advance, and a substitute can be easily obtained even if the user loses the coin. Can be discharged.

  When the cover member has a locking portion that locks the tip of the coin when the coin is inserted between the protruding portion and the upper surface of the push button, the inserted coin can be firmly held in a horizontal state.

  Further, when the lower surface of the protrusion is parallel to the upper surface of the push button, the inserted coin can be securely held.

Next, an embodiment of an injection member used for the aerosol product of the present invention will be described with reference to the drawings. 1 to 15 are drawings showing embodiments outside the scope of the present invention. 16a is a side sectional view showing an embodiment of the injection member of the present invention, FIG. 16b is a plan view thereof, FIG. 16c is a partial perspective view of the injection member, and FIGS. 16d and 16e are protrusions used for the injection member. 16f is a partial perspective view showing another embodiment of a protrusion used for the injection member, FIGS. 17a and 17b are side sectional views showing means for attaching coins to the injection member of FIG. 16a, FIG. 17c is a side sectional view showing a means for removing the injection member, and FIGS. 18a, 18b, 18c, and 18d are a front view, a rear view, a side sectional view showing still another embodiment of the injection member of the present invention, It is a top view.

  An aerosol product 10 shown in FIG. 1 includes an aerosol container 13 including a pressure-resistant container 11 and an aerosol valve 12 (hereinafter referred to as a valve) fixed to the opening of the pressure-resistant container, and an injection member 14 attached to the head of the aerosol container. And an aerosol composition A filled inside the aerosol container.

  The pressure vessel 11 is a conventionally known one, and a bottom portion 11a and a metal base 11c are fixed to a barrel portion 11b made of a metal plate such as tin or tin-nickel steel plate (TNS) by double winding. The bead part 11d is formed in the upper end opening of the metal eyepiece. In addition, as the pressure vessel 11, for example, a metal plate made of aluminum, tin or the like is formed into a bottomed cylindrical shape by impact processing or drawing processing, and further a shoulder portion and a bead portion are formed by necking processing or curling processing. May be. Further, other materials having pressure resistance such as synthetic resin and pressure glass may be used.

  The valve 12 is also a conventionally known one, and includes a mounting cup 19 that is fixed to the bead portion 11d of the pressure vessel 11, a cylindrical housing 20 that is held in the center of the mounting cup, and is movable up and down within the housing. A stem 21 that is housed and is constantly biased upward by a spring, and a stem rubber that covers the stem hole of the stem and seals the inside of the aerosol container in a state where the stem 21 is biased upward by the repulsive force of the spring (see FIG. And a dip tube 22 extending from the lower end of the housing to the bottom of the pressure vessel main body.

  The injection member 14 includes a cover member 24 attached to the head of the aerosol container (a curled portion of the mounting cup) and a push button 25 attached to the upper portion of the stem. As shown in FIGS. 2a to 2d, 3a, and 3b, the cover member 24 includes a mounting portion 27 for mounting on a curled portion of the mounting cup, and a pair of side wall portions 24a that cover both side surfaces of the push button 25. It has. The side wall portion 24a extends upward from the mounting portion 27 so as to cover both side surfaces of the push button 25, and the top surface of the side wall portion 24a is located higher than the top surface 25a of the push button. The side wall 24a can prevent malfunctions such as accidental injection of the aerosol composition by hitting the push button 25 when not in use, and it can be prevented by a finger during normal use and a coin during discharge operation. Can be used to easily push down the push button 25 vertically downward, and the valve can be opened reliably. As shown in FIG. 2b, a slit 30 extending in the horizontal direction is formed at the rear part of the side wall part 24a. The width of the slit 30 is 1 to 3 mm, preferably 1 to 2.5 mm, and the lower surface 30a of the slit 30 is located below the top surface 25a of the push button with the push button 25 not being pushed down. .

The injection hole side (front surface) of the cover member 24 is recessed so that the injection hole 36 is exposed even when the push button 25 is pushed down, and the rear side of the cover member 24 can be pushed down with the finger on the head of the push button. It is so depressed.
The push button 25 includes a stem mounting portion 35 for mounting on the stem 21, an injection hole 36 for injecting the aerosol composition to the outside (atmosphere), and a passage 37 connecting the stem mounting portion 35 and the injection hole 36. (See FIG. 3a).

  The coin 16 is a thin disk as shown by an imaginary line in FIG. 2d, and has a diameter of 20 to 30 mm and a thickness of 1 to 3 mm. Coins, medals and the like can be used. The coin is preferably made of a metal such as copper, zinc, tin, nickel, aluminum and a mixture (alloy) thereof, and has higher hardness than a cover member made of synthetic resin such as polyacetal, polyamide, polyolefin, polyester, Easy to insert coins and easy to pull out coins. Further, it is preferable that the thickness of the coin 16 is slightly larger than the width of the slit 30. Thus, when the coin 16 is inserted into the slit 30, the coin 16 is difficult to be removed due to friction between the coin and the slit. Further, since the coin 16 used in daily life can be used as the coin 16, even if the attached coin is lost, the coins can be discharged using these coins. In this embodiment, the coin 16 is provided in the aerosol product. However, since everyday items such as coins can be used, the coin 16 may not be provided as an accessory of the aerosol product.

  When the aerosol product 10 to which such an injection member 14 is attached is placed in normal use, the stem is pushed down together with the push button to open the stem hole of the valve by pushing down the top surface 25a of the push button with a finger. The At this time, the inside of the aerosol container communicates with the atmosphere, and the aerosol composition inside the aerosol container is supplied to the inside of the housing through the dip tube, and further injected into the atmosphere from the injection hole via the stem hole and the push button passage. Is done.

  When the aerosol product is no longer needed and is to be discarded, the top surface 25a of the push button is pushed down with a finger or the like, and the coin 16 is inserted into the slit 30 in this state. At this time, since the top surface 25a of the push button is in contact with the lower surface of the coin 16, the push button 25 does not rise even when the finger is released, and is maintained at the position where the aerosol valve is opened (see FIG. 3b). While the coin 16 is inserted, the aerosol product is maintained in an open state communicating with the atmosphere, so that the entire amount of the aerosol composition remaining inside the aerosol container can be discharged. In addition, since the repulsive force of the spring is applied to the coin 16 inserted into the slit 30 upward in the axial direction of the container via the push button 25, the radial frictional force between the coin 16 and the slit 30 is further increased. The coin 16 is difficult to come off. When the discharge from the aerosol product stops, the coin 16 can be collected by pulling out the coin 16. Note that it is more preferable to discard the coins 16 with the coins 16 attached since the person collecting the aerosol products can recognize that the aerosol products have been discharged. In this case, it is preferable to use a coin made of the same material as that of the pressure vessel because it is easy to recycle.

  FIG. 4a shows an injection member 40 that can be used in place of the injection member 14 of FIG. The injection member 40 is formed such that the rear portion of the upper surface of the push button 41 is tapered, and the other configuration is substantially the same as the injection member 14 of FIG. The push button 41 has an end 42 at the rear of the upper surface formed below the lower surface 30a of the slit 30 formed in the cover member 24, and is tapered from the end 42 toward the front upper portion 43 of the button ( An inclined surface 44) is formed. In this embodiment, the abutting portion extends from the inclined surface 44 to the upper surface front portion 43.

  Thus, when disposing of the aerosol product, when the consumer inserts the coin 16 into the slit 30 and pushes it in, the coin 16 comes into contact with the inclined surface 44 of the push button to push the push button. A force downward to the container axis is applied to 41, and the push button 41 is lowered. Then, as shown in FIG. 4b, when the coin 16 is pushed all the way into the slit 30, the coin 16 comes into contact with the upper front portion 43 of the button, the button is pushed down, and is maintained in the valve open position. Also in this case, since the coin 16 receives a vertical upward force by the spring via the button 41, the horizontal frictional force between the coin 16 and the slit 30 increases, and it becomes more difficult to come off.

  The injection member 45 shown in FIG. 5a is formed in an inverted “<” shape in which the upper surface 47a of the slit 47 of the cover member 46 extends obliquely downward from the upper surface of the cover member 46, and is bent halfway forward in the horizontal direction. The lower surface 47b of the slit 47 of the cover member 46 is horizontally formed forward from the rear side surface of the cover member, and a recess 48 is formed in the middle thereof. That is, the slit 47 includes an insertion portion 49a and a locking portion 49b. Other configurations are substantially the same as those of the injection member 14 shown in FIG.

  Since it is comprised in this way, the coin 16 is inserted in the injection member 45 as follows. First, the coin 16 is inserted into the insertion portion 49a in alignment with the upper surface 47a, and a force is applied in the coin insertion direction to push down the upper surface (contact portion) of the push button 25 to open the aerosol valve. And when the front-end | tip (lower end) of the coin 16 contact | abuts to the recessed part 48, the coin 16 is fallen in a horizontal direction like the arrow of FIG. Finally, the coin 16 is pushed into the locking portion 49b (see FIG. 5c). Thereby, the coin is locked by the locking portion 49b, and the push button is maintained at the open position of the aerosol valve. This injection member 45 is also pushed down and held in that state without performing an operation of pushing the push button. In the injection member 45, the recess 48 may be omitted. However, coins can be inserted more smoothly when the recess 48 is formed.

  The injection member 55 shown in FIG. 6A has an upper surface 57a of the slit 57 of the cover member 56, which is formed in a "<" shape that extends horizontally forward from the side of the cover member and inclines upward in the middle. The lower surface 57b of the slit of the cover member 56 is formed in parallel with the inclined surface in front of the upper surface 57a. And the slit 57 is also comprised from the insertion part 58a and the latching | locking part 58b. Other configurations are substantially the same as those of the injection member 14 shown in FIG.

  Since it is comprised in this way, the coin 16 is inserted in the injection member 55 as follows. First, the coin 16 is inserted horizontally until it is in contact with the lower surface 57b of the slit while being aligned with the upper surface 60a (contact portion) of the push button 60 (see FIG. 6b). Here, as shown by the arrow in FIG. 6b, the coin 16 is rotated downward about the bent portion 62 of the upper surface 57a. As a result, the push button 60 is pushed downward to open the valve. In this state, the coin 16 is pushed into the locking portion 58b of the slit 57, whereby the push button 60 is held down. At this time as well, since the coin 16 receives the repulsive force of the spring in the axial direction of the container via the push button 60, it is difficult to come off. In this case, when the coin 16 is inserted into the slit 57, the push button 60 is not pushed down, so that the coin 16 can be easily inserted into the slit 57. Further, since the coin 16 is pushed down using the lever principle after being inserted into the slit 57, it is very easy to rotate the coin, that is, push down the push button 60. That is, it is possible to easily discharge the aerosol composition remaining in the aerosol container.

In the ejection member 65 shown in FIG. 7 a, the slit 67 of the cover member 66 is formed obliquely, and the width of the slit 67 is formed slightly smaller than the thickness of the coin 16. A step portion 69 is formed at the rear portion of the push button 68. The other structure is substantially the same as the injection member 14 of FIG.
Since it is configured in this manner, the coin 16 is inserted into the slit 67 in an oblique manner. Here, the front end (lower end) of the coin 16 and the step portion 69 (contact portion) of the push button are brought into contact with each other and inserted into the slit 67, whereby the push button 68 can be held in a depressed state (see FIG. (See FIGS. 7b and 7c). The coin 16 receives the repulsive force of the spring in the axial direction of the container via the push button 68, but the friction between the coin 16 and the slit 67 is caused because the thickness of the coin 16 is slightly larger than the width of the slit 67. The force prevents coins from coming off. In this embodiment, the lower end of the slit 67 is formed to be lower than the step portion 69 of the push button, but the lower end of the coin inserted into the slit may be lower than the step portion of the push button. The positional relationship between the slit and the push button is determined by the size or structure of the cover member, coin, or the like.

  Moreover, you may provide the slit 72 of the cover member 71 in the axial direction or the perpendicular direction of a cover member like the injection member 70 shown to FIG. The other structure is the same as the injection member 65 of FIG. Thus, by inserting the coin 16 vertically into the slit 72, the lower end of the coin 16 comes into contact with the top surface (contact portion) of the push button, and the aerosol composition remaining in the aerosol container can be discharged. .

  Further, when such an injection member 70 is used, a cap 75 that can lock the coin 16 vertically as shown in FIG. 8B can be used. The cap 75 is formed with a coin engaging portion 76 into which the coin 16 can be inserted. The width of the coin engaging portion 76 is preferably slightly smaller than the thickness of the coin. A communication hole 77 communicating with the outside air is formed on the top surface of the cap. By attaching the cap 75 with the coin 16 locked to the cover member 71 in this way, the coin 16 is inserted into the slit 72 of the cover member 71 and the push button can be pushed down. Thereby, since the aerosol composition can be discharged with the cap attached, the discharged aerosol composition remains in the cap, and the discharged aerosol composition adheres to the user. There is no fear of sucking the aerosol composition, which is preferable. At this time, since the injection gas is discharged to the outside air through the communication hole 77, the cap does not explode. Further, it is preferable that a liquid absorbent such as tissue paper, sponge, water-absorbing resin, etc. is stored in the cup and the discharging operation is performed so that the stock solution does not overflow from the cap.

  Thus, when the slit is provided in the axial direction or the vertical direction of the cover member, a push button 70a shown in FIG. 8c may be used. The push button 70a has a groove 73 formed in the left-right direction of the top surface so as to correspond to the coin guided by the slit of the cover member. This ensures contact with the coin 16. Similarly to the slit of the cover member, the groove 73 is formed to have a width slightly smaller than the thickness of the coin, so that the contact (insertion) with the coin becomes firm.

  Further, a cap 80 as shown in FIG. 8d may be used. The cap 80 is formed with an insertion hole 81 into which the coin 16 can be inserted into the upper surface 80a of the cap. And the width | variety of the both ends 82 of the insertion hole 81 is a little narrow (refer FIG. 8e). In this case, the aerosol composition can be discharged by inserting the coin 16 into the insertion hole 81 and attaching the cap 80 to the cover member of the injection member 70 to push down the push button. Further, since both end portions 82 of the insertion hole 81 are slightly narrowed, even if the coin 16 is inserted into the insertion hole 81, both end portions 82 of the insertion hole communicate between the inside of the cap 80 and the outside air. In particular, the cap does not explode even if other communication holes are not formed.

  Further, when such a cap is used, since the coin can be fixed with the cap, the width of the slit 67 of the ejection member is not particularly limited as long as the coin 16 can be inserted.

The injection member 85 shown in FIG. 9 is one in which a slit is not formed in the cover member 86, a pair of side wall portions 86 a, a conventionally known cover member 86 having an engagement protrusion 86 b at the lower portion, and front and rear surfaces of the top surface. A push button 87 in which a groove 88 is formed in the direction and a cap 80 in FIG. 8 d in which a fitting hole 81 for locking the coin 16 is formed.
Since the injection member 85 is configured in this way, the coin is inserted into the groove 88 formed on the top surface of the push button from the pair of side wall portions 86a. At this time, the push button 87 has not been pushed down yet. Thereafter, the cap 80 is put on the cover member 86. As a result, the upper end of the coin and the insertion hole 81 of the cap come into contact with each other, and the push button 87 is pushed down by the coin by further pushing down the cap 80. The cap 80 is fixed to the cover member 86 by engaging the lower end of the cap 80 with the engagement protrusion 86b of the cover member. In this embodiment, the cover member is not provided with a slit, but the coin is fixed by the groove 88 (locking portion) formed in the push button and the insertion hole 81 (locking portion) formed in the cap. The push button can be pushed down reliably without coins being shaken. The spray member 85 is also preferable because the aerosol composition does not diffuse because the cap is attached to perform the discharging operation.

  Moreover, although the cap 80 of FIG. 8d was used as a cap, you may use the cap 75 of FIG. 8b. In this embodiment, a groove is used as the coin locking portion of the push button and a slit is used as the locking portion of the cap. However, the coin is locked between the top surface of the push button and the top surface of the cap. However, these are not particularly limited.

The injection member 90 shown in FIG. 10 a includes a lever-type push button 91 attached to the upper part of the stem and a cover member 92 attached to the head of the aerosol container 101. Moreover, the aerosol product 102 shown in FIG. 10 b is obtained by filling the aerosol container A with the aerosol composition A and attaching the injection member 90 to the aerosol container 101.
The push button 91 is an L-shaped cylindrical push button body 95 having an injection hole 93 formed at one end, and a stem engagement portion 94 formed at the other end. The lever 96 is formed so as to protrude forward (injection hole side) downward from the push button main body, and the hinge 97 is formed to protrude rearward from the push button main body and has an end serving as an engagement pin. Composed.

The cover member 92 includes a mounting portion 98, a pair of side wall portions 99 a and 99 b that cover both side surfaces of the push button 91, and a hinge engaging portion 100 that engages with an engaging pin of the hinge 97. Further, a slit 103 of about 1.0 to 3.0 mm is formed in the horizontal direction so that the front side is open at the front part (injection hole side) of both side walls of the cover member 92.
When the stem engaging portion 94 of the push button 91 of the injection member configured in this way is attached to the stem, and the hinge 97 of the push button 91 is attached to the hinge engaging portion 100 of the cover member 92, the lever 96 has a side wall portion. It is arranged so as to protrude forward from 99a, 99b, and the height of the lower bottom of the slit 103 is arranged at a position lower than the upper surface of the push button 91.

When using the aerosol product 102 to which such an injection member 90 is attached, the head of the aerosol product (the injection member 90 and the head of the aerosol container 101) is gripped, and the lever 96 of the push button 91 is pushed with an index finger or By pulling with the middle finger, the push button 91 swings downward about the rear end of the hinge 97 to push the stem downward, the stem hole of the valve of the aerosol product is opened, and the aerosol composition is sprayed.
When it is desired to discard the aerosol product 102, the coin is inserted into the slit 103 in a state where the push button 91 is pushed down (a state where the lever is pulled). As a result, the coin inserted into the slit 103 comes into contact with the upper surface of the push button body 95 of the push button 91, and the push button 91 is kept depressed even when the lever 96 is released. Therefore, the aerosol product 102 is maintained in an open state, and the entire amount of the aerosol composition can be discharged.
Such a lever-type push button 91 is preferable because the push button 91 can be easily pushed down and a coin can be easily inserted.

In the injection member 105 shown in FIGS. 11a and 11b, slits 106a and 106b are formed in the side wall portion 99 of the cover member 92 and the lever 96 of the push button 91, and other configurations are substantially the same as those in FIG. This is the same as the injection member 90.
The side wall slit 106a is formed in the front portion of the side wall portions 99a and 99b in the horizontal direction, and the lever slit 106b is formed in the front side of the lever 96 of the push button 91 in the horizontal direction. These slits 106a and 106b are arranged to overlap each other when the lever 96 is pulled and the push button 91 is pushed down. Thereby, when the push button 91 is pushed down, coins can be simultaneously inserted into both slits 106a and 106b. Thereby, even if the finger is released from the lever 96, the aerosol product is kept open.

In the injection member 110 shown in FIGS. 12a and 12b, the slit 111 is formed on the upper portion of the side wall portion 99 of the cover member 92 from the upper end downward in the axial direction of the aerosol product. 10 injection members 90 are the same.
By forming the slit 111 in the upper part of the side wall 99, the push button is pushed down at the same time as the coin is inserted, and the slit and the coin are engaged as in the injection member 70 of FIG. 8a to keep the aerosol product open.

13A includes an injection member main body 118 (see FIG. 13B) including a lever-type push button 116 and a cover member 117, and a cap 119 that covers the injection member main body 118.
