An aerosol container consists of a pressure-resistant container and an aerosol valve attached to the opening of the container. 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.

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.

  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 with an inclination. 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 the coin 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.
This injection member main body 118 has engagement grooves 121 formed on both side walls 120 of the cover member 117, and the other configuration is substantially the same as the injection member 90 of FIG.
The cap 119 is a rectangular parallelepiped and has at least a front surface 119a, both side surfaces 119b, and an upper surface 119c. When the cap 119 is mounted on the injection member main body 118 on the upper surface 119c, the cap 119 is interposed between the side wall portions 120 of the cover member 117. The slit 123 formed so that it may become parallel with the side wall part 120 is provided. An engaging protrusion 124 that engages with the engaging groove 121 is formed at the lower end of the cap side surfaces 119b. Furthermore, an absorbent body 125 such as a sponge is provided on the front surface 119a of the cap 119 facing the injection hole 122 so that the contents discharged from the injection hole 122 are not scattered.

  Since the ejection member main body 118 and the cap 119 are configured in this way, the cap 119 disposed inside so as to fit the coin 126 into the slit 123 is inserted by being inserted from above the ejection member main body 118. With this mounting method, the cap can be mounted without dropping coins arranged on the inner surface of the cap. At the same time that the cap is mounted, the coin 126 disposed between the side walls 120 of the cover member pushes down the push button 116 (see FIG. 13c). Further, since the engagement groove 121 of the injection member main body 118 and the engagement protrusion 124 of the cap engage with each other, the aerosol product to which the injection member 115 is attached is maintained in an open state and the content remaining in the aerosol container. The whole thing can be discharged. In this embodiment, since the discharged contents are absorbed by the absorber inside the cap, the contents can adhere to the user or the user can be prevented from sucking the contents and discharged safely. Can do.

  Further, as a means for engaging the injection member main body 118 and the cap 119, a slide groove and a protrusion may be provided on the side wall portion of the cover member and the side surface of the cap, respectively, and the cap may be inserted into the slide member from the front of the injection member main body. .

Further, a locking portion 153 is formed on a part of the top surface 152 of the cover portion, and the lower surface 153a of the locking portion is the same height as the top surface 151a of the operation portion or slightly higher than the top surface 151a of the operation portion. It is configured to be low.

  In normal use, the injection member 130 configured as described above is configured such that when a finger is inserted into the upper opening 147 and the operation unit 151 is operated, the push button 131 is pressed down to open the valve, and the aerosol container 130 The aerosol composition flows out into the L-shaped passage 145 via the stem. At this time, when the injection nozzle is parallel to the axis of the aerosol container as shown in FIG. 14, the aerosol composition is injected from the L-shaped passage 145 through the second passage 141 to the outside through the injection hole 142 of the tip 143. . On the other hand, when the injection nozzle is rotated 90 degrees to be perpendicular to the axis of the aerosol container, the aerosol composition is injected from the L-shaped passage 145 through the first passage 137 to the outside through the injection hole 139 of the injection unit 140. Is done.

  In addition, when the aerosol product is no longer needed and is to be discarded, the coin 16 is inserted from the upper opening 147 of the cover portion, and the operation portion 151 is pushed down while the lower surface 153a of the locking portion is interposed between the top surface 151a of the operation portion. A coin 16 is inserted (see FIGS. 15a to 15c). The inserted coin 16 is firmly held because it abuts against the locking portion lower surface 153a with the repulsive force of the valve spring applied from below. Thereby, it can hold | maintain in the state which pushed down the push button 131, ie, the state which connected the aerosol container inside and air | atmosphere, and can discharge | emit whole amount of the aerosol composition which remained in the aerosol container inside. In this embodiment, the operation unit 151 is connected to the cover unit 149 and the thin wall unit 150, but may be integrated with the push button 131.

  16a and 16b includes an attachment part 161 attached to an aerosol container and a cover member 163 having a pair of side wall parts 162 extending upward from the attachment part, and an aerosol composition in three directions. The push button 165 is equipped with an injection nozzle 164 having three injection holes 164a, 164b, and 164c for simultaneous injection. As shown by a two-dot chain line in FIG. 16b, two inwardly protruding projections (projections) 166 are formed on the inner surface of the side wall 162 on the surface including the central axis (stem) of the aerosol container. A locking step (locking portion) 167 is formed at the upper portion of the side wall portion on the injection hole side. The protrusion 166 includes a protrusion upper portion 166a having a top surface inclined with respect to the inner surface of the side wall portion and a protrusion lower portion 166b having a lower surface parallel to the top surface of the push button (see FIGS. 16c to 16e). ). Further, the top surface of the push button is provided with arc-shaped side walls 165b protruding from both side ends thereof. When the push button is not depressed, the upper end of the side wall 165b is the same as the lower surface 166b of the protrusion or from the lower surface 166b. Is also preferably above. Furthermore, it is preferable that the lower surface 166b of the protrusion and the lower surface 167a of the locking step portion have the same height so that the inserted coin can be held in a horizontal state. The top surface 165a of the push button may be provided with an indication indicating the type of aerosol composition and the injection direction, such as a mark or Braille.

  In the normal use, the injection member 160 configured in this manner opens the valve when the top surface 165a of the push button is depressed with a finger, and the aerosol composition inside the aerosol container passes through the stem and the passage in the push button. The three jet holes 164a, 164b, and 164c are jetted in an upward oblique direction, a horizontal direction, and a downward oblique direction, respectively. The ejected particles do not reach far because the energy of the jet is dispersed in three directions, but diffuse in a wide range at a short distance. In addition, the sprayed particles are not as fine as a hair spray or a space pesticide, so they do not bounce when sprayed onto the floor surface. For example, they are suitable for aerosol products that are sprayed onto carpets and tatami mats. Can be used.

  When the aerosol product is no longer needed and is to be discarded, first, as shown in FIG. 17A, the coin 16 is inserted obliquely from above between the locking step 167 at the upper side of the side wall and the upper protrusion 166a at the inner surface of the side wall. At this time, it is preferable that the coin is inserted until the tip 16a contacts the inner wall of the side wall. Next, when the rear end 16b of the coin 16 facing obliquely upward is pushed downward from the state shown in FIG. 17a, the coin 16 is positioned on the protrusion upper portion 166a around the contact portion between the tip 16a of the coin and the inner wall of the side wall. It moves downward along the slope, further over the protrusion, and the upper surface of the coin is locked to the lower protrusion surface 166b (see FIG. 17b). Thereby, the push button is pushed down to a position where the valve is opened. At this time, the coin 16 is held between the lower surface 167a of the locking step portion and the lower surface 166b of the protrusion and the side wall 165b of the push button, and can be held in a state where the inside of the aerosol container and the atmosphere are in communication with each other. The entire aerosol composition remaining inside can be discharged.

  Further, the injection member 160 is provided with a slit 168 slightly above the cover member mounting portion 161. The slit 168 is a means for removing the cover member 163. By inserting the coin 16 into the slit 168 and lifting the rear end 16b of the coin in the direction of the arrow in FIG. 17c, the coin comes into contact with the valve and becomes a fulcrum. The cover member can be removed from the aerosol container using the principle. Thus, after the aerosol composition in the aerosol container is discharged using a coin, the synthetic resin cover member can be subsequently removed from the metal aerosol container using the coin, making it easy to separate and discard.

  FIG. 16 f shows another form of the protrusion used for the injection member 160. The protruding portion 169 includes a protruding portion upper portion 169a and a protruding portion lower portion 169b. The upper end of the projecting portion upper portion 169a is connected to the side wall portion 162, and projects from the upper end while inclining inward toward the side wall portion. Further, the protruding portion lower portion 169b extends vertically downward from the lower end of the protruding portion upper portion. Furthermore, a slit is formed below the connecting portion (upper end of the upper portion of the protruding portion) with the protruding portion 169 of the side wall portion 162. Since it is configured in this manner, when the coin is inserted obliquely as shown in FIG. 17a and pushed down near the rear end of the coin so that the coin is parallel, the protruding portion bends downward, and the protruding portion 169 itself is a leaf spring. Acts as Therefore, when operating from the state of FIG. 17a to the state of FIG. 17b, the operation can be performed more smoothly.

  18a includes a cover member 171 attached to the head of the aerosol container and a push button 172 attached to the stem. The cover member extends upward from the attachment portion 173 and the attachment portion. A pair of side wall portions 174a and 174b and a slit 176 are provided in the upper rear portion of the mounting portion (FIG. 16b). A projection 175 that protrudes inward is formed on the inner surface of each of the side wall portions 174a and 174b, and is slightly below the upper portion of the side wall portion on the injection hole side. A locking step 177 extending in the direction is formed. Two protrusions 175 are provided rearward from the central axis of the aerosol container. Similarly to the injection member 160 of FIG. 16, the push button 172 also has arc-shaped side walls 172b projecting from both ends of the top surface 172a. When the push button is not depressed, the upper end of the side wall 172b is from the lower surface 175b of the protrusion. Is also above (FIG. 18c). Moreover, you may provide the display which shows the kind and injection direction of an aerosol composition, for example, a mark, Braille etc., on the top | upper surface 172a of a pushbutton.

  In the normal use, the injection member 170 configured as described above opens the valve when the top surface 172a of the push button is pushed down with a finger, and the aerosol composition inside the aerosol container passes through the stem and the passage in the push button. Injected from the injection hole. In this embodiment, since the aerosol composition is ejected from one ejection hole, the ejected particles are likely to reach far away, and are preferably used for aerosol products such as insecticides that are ejected into the space.

  Further, when the aerosol product is no longer needed and is to be discarded, the coin 16 is inserted obliquely from above between the locking step 177 at the upper side of the side wall and the projection upper surface 175a at the inner side of the side wall, as in FIG. 17a. . Next, when the rear end 16b of the coin is pushed downward, the coin 16 moves downward along the slope of the protrusion upper surface 175a, and further climbs over the protrusion, whereby the coin upper surface is locked from the protrusion lower surface 175b and the valve is opened. Held at a position. At this time, the coin 16 is held between the lower surface 177a of the locking step portion and the lower surface 175b of the protrusion and the side wall 172b of the push button, and can be held in a state where the inside of the aerosol container and the atmosphere are in communication with each other. The entire aerosol composition remaining inside can be discharged. Furthermore, by inserting the coin 16 into the slit 176 of the cover member and lifting the rear end of the coin, the cover member can be removed from the aerosol container using the lever principle.
