Aerosol container cap and aerosol injection device

Technical field

TECHNICAL FIELD [0001] The present invention relates to an aerosol container cap and an aerosol injection device, and more specifically, an aerosol container cap capable of easily discharging the contents in an aerosol container after use, and the aerosol container cap. The present invention relates to an aerosol injection device to which is attached.

Background art

[0002] The aerosol spray device can easily spray, spray or apply the contents in a container, so it can be used for paints, insecticides, fragrances, deodorants, household cleaners, fungicides, Widely used for spraying disinfectants, pharmaceuticals, cosmetics, quasi drugs and the like. In this aerosol type spray device, the propellant and the gas for injection are accommodated in the aerosol container, and the propellant is injected through the nozzle by pressurization by the gas for injection. In the present specification and claims, the “contents” in the container includes the propellant and the gas for injection, and even when the propellant and the gas for injection are only! , Sometimes referred to as “content”. “Aerosol” refers to a liquid, gas, powder, etc., which is ejected through a nozzle in terms of container force, and includes spray forms such as mist, particulate, foam, paste, and gel. “Discharge” with respect to the contents means that the remaining contents are discharged for the purpose of disposing of the aerosol container unless otherwise specified.

[0003] As the gas for injection, the use of CFCs is prohibited, and high-pressure gases such as flammable butane and liquid gases such as propane, nitrogen gas, and carbon dioxide gas are currently used. If the used aerosol container is disposed of as garbage, there is a risk that the container will explode due to the gas in the container. In order to prevent such an accident, when disposing of an aerosol container, it is desirable to discharge the contents in the container to the normal pressure before disposing of it. Will prompt you to discharge the contents of the container before disposal.

[0004] Aerosol containers that are widely used are mainly nozzle heads attached to the stem. The cover is covered with a cap, and when used, the cap is removed and the nozzle head is pressed to push down the stem to spray the contents (called a two-touch type) and the spray button with a nozzle that removes the cap (Hereinafter, abbreviated as “button”) There is a type (called one-touch type) in which the contents are sprayed by pushing down the stem by pressing.

[0005] In the case of these conventional aerosol containers, it may take a long time to keep discharging the contents in the container through the nozzle and to keep the internal pressure at a normal pressure, which is not always easy. In addition, there is a method of making a hole in an aerosol container using a cone-shaped tool with a sharp tip and discharging the contents, but in general the contents may be ejected toward the human body. Therefore, it is not a preferable method. Therefore, the actual situation is that an aerosol container is often discarded without the contents being discharged.

[0006] In order to solve the above problems, several methods have been proposed for discharging the contents of the container, such as the gas in the container and the remaining propellant using a cap and button for the aerosol container. Yes. In the case of a two-touch type aerosol container, the nozzle head usually attached to the stem of the container is removed, a part of the cap is brought into direct contact with the stem, and the cap is placed in the aerosol container part with the stem pushed down. A type of cap that is fixed and discharges contents directly from the stem has been proposed (for example, Patent Documents 1 to 3). In addition, when discharging the contents, the cap is not removed and the nozzle head is pressed down with the pressing piece on the top of the cap, and the contents are discharged by locking it in the pressed down state. A cap has also been proposed (Patent Document 4).

[0007] On the other hand, in the case of a one-touch type aerosol container, there has been proposed a cap of a type in which the button is locked with the stem pushed down and the contents are discharged through the nozzle head (for example, a patent Reference 5, 6). The caps of the one-touch type aerosol container disclosed in Patent Documents 5 and 6 are as follows.

FIG. 20 is a cross-sectional view showing an “inclination-actuated spray head structure” (hereinafter referred to as a cap) disclosed in Patent Document 5, wherein (a) is a state when not in use. (B) shows the state during normal use, and (c) shows the state when the contents are discharged. The cap is composed of a cap body 111 and a button 113. When the button 113 is pressed on the upper surface of the button 113, the flexible connecting portion As shown in FIG. 20 (b) or (c), the stem 112 is tilted to the right as shown in FIG. 20 (b) or (c) so that the stem 112 can be pushed down. In the case of this cap, during normal use, it is sprayed in the state shown in FIG. 20 (b), and when the contents in the container are discharged, the button 113 is further pushed in, and the locking formed at the lower part of the button. The protrusion 116 is locked by a receiving portion 117 of a locking protrusion 116 formed on the cap body. Therefore, the injection is maintained with the hand released from the button 113, and all the contents are discharged.

FIG. 21 shows a “residual gas removing lid device for an aerosol container” disclosed in Patent Document 6.

FIG. 2 is a cross-sectional view (hereinafter referred to as a cap), where (a) shows a state when not in use, and (b) shows a state when the contents are discharged. The cap is composed of a cap body 121 and a button 122. When discharging the contents in the container, push the button 122 down to the position when the contents are discharged as shown in Fig. 21 (b). In this state, the button 122 is held in the state of jetting the contents by the “cap side wall protrusions” 127 being locked by the “guide wall protrusions” 128. In this way, the cap disclosed in Patent Document 6 can be pushed down only to the aerosol container side, and the contents in the container continue to be discharged by the button 122 having a structure that does not reverse! .

FIG. 22 is a cross-sectional view showing the “residue release mechanism of an aerosol container” (hereinafter, “residue release mechanism” is referred to as a cap) disclosed in Patent Document 7, and (a) is a non-existing view. State during use (or state during normal use), (b) shows the state when the contents are discharged. The cap includes a shoulder cover 133 and a button 131. The button 131 is removably inserted into the central hole 139 of the shoulder cover 133. As shown in Fig. 22 (a), when not in use, the button 131 has the nozzle 132 attached to the front recess 141 formed in the shoulder cover 133. An object is jetted from the nozzle 132.

[0011] On the other hand, when discharging the contents, first remove the shoulder cover 133 from the container A force, and then remove the button 131 from the shoulder cover 133 force. Next, as shown in FIG. 22 (b), the button cover 131 is rotated 180 ° horizontally so that the nozzle 13 2 faces the rear recess 140 formed in the shoulder cover 133, that is, the shoulder cover 133 Attach to the central hole 139. By mounting in this way, the protrusion 137 of the button 131 is formed in the shoulder cover 133. 38, the button 131 is locked at a low position with respect to the shoulder cover 133, and the upward movement is prevented. By attaching the shoulder cover 133 to the container A in this state, the stem 135 is maintained in a pushed down state, and the contents in the container are continuously discharged through the rear recess 140.

[0012] In the case of the cap disclosed in Patent Document 5, the contents, that is, the propellant gas and the propellant are diffused around the aerosol container. Some contents are harmful to the human body, and some are contaminated with paint. In addition, if the gas used for ignition ignites, it may flash back to the container and there is a risk of explosion. In addition, if the button 113 is pressed strongly by mistake, the contents are released, and once the button 113 is pressed, it is difficult to return the contents to a non-use state. Further, in the case of the cap disclosed in Patent Document 6, the movement of the button 122 is in one direction and cannot be returned. Therefore, there is a drawback that it is difficult to stop the release of the contents halfway, such as when the button 122 is accidentally pressed down to the release state. Further, in the case of the cap disclosed in Patent Document 7, as in the case of the cap disclosed in Patent Document 5, the contents are diffused around the aerosol container. Some contents are harmful to the human body and others such as paint may contaminate the surroundings. In addition, in the case of an aerosol container using these caps, the contents in the container are discharged through the nozzle, so that it takes a long time to bring the internal pressure to normal pressure. .

Therefore, when the aerosol container is discarded, the contents such as the propellant to be injected and the gas for injection remaining in the container can be surely discharged to the area surrounded by the cap body, the button and the container. it can. Since this discharge is performed directly from the opening of the valve stem without passing through the nozzle, it is performed in a large amount and can be completed in a short time. In addition, since the container stem is also released by removing the cap body, the pressure on the valve stem is released, so that the discharge of the contents can be easily stopped if necessary. Thus, with the aerosol container cap Then, the contents remaining in the container can be safely discharged by a simple operation.

[0016] Further, in the aerosol container cap according to the present invention, the content discharged from the aerosol container is surrounded by the cap body and the aerosol container on the top surface of the button in the aerosol container cap. It is possible to provide a flow path for discharging contents to be discharged to the specified area.

[0017] According to the aerosol container cap, the button top surface is provided with a flow path through which the container force is discharged, and the outflow of the discharged contents is hindered by the button top surface. It can be reliably and quickly discharged to the area surrounded by the cap body, buttons, and containers.

[0018] Further, the aerosol container cap according to the present invention is the aerosol container cap, wherein the fitting portion of the cap body is such that the contents of the aerosol container are surrounded by the cap body and the aerosol container. When being discharged into the area, it is configured to fit tightly into the tightened portion between the body portion of the aerosol container and the mountain cap, and to maintain the fitting state against the injection pressure It can be.

[0019] According to the aerosol container cap, the cap body is tightly fitted to the container, and the fitting state is maintained by being piled on the injection pressure, so even if the finger is released from the cap body, The contents can be discharged stably and safely.

[0020] Further, in the aerosol container cap according to the present invention, in the aerosol container cap, the locking means is formed on a locking protrusion formed on a side wall of the button and on a side wall of the button mounting portion. The protrusion guides corresponding to the locking protrusions can be used.

Locking protrusion or protrusion guide and the side wall of the button mounting part of the cap body Therefore, the structure is simple and the manufacturing is easy.

[0023] Further, in the aerosol container cap according to the present invention, the locking protrusion or the protrusion guide in the locking means is configured so that the button is turned upside down with respect to the button mounting portion. When inserting, the cap body may be configured so that it can be inserted into the upper and Z or downward force of the cap body.

[0024] According to the aerosol container cap, the button can be pushed into the button mounting portion in the upside down direction with the cap body mounted on the container. In the case of an aerosol container cap provided with the above button locking means, there is an advantage that it is easy to grasp the timing of discharging the contents of the container.

[0025] Further, the cap for an aerosol container according to the present invention is such that when the button is pushed down during normal use of the aerosol container, the valve stem is pushed down as a fulcrum of rotation of the button. The locking means prevents tilting of the button when the button is pushed down together with the valve stem in a state where the button is inserted in the upside down direction in the button mounting portion. And an auxiliary locking portion for maintaining the posture so that the contents can be discharged, and the locking portion includes the fulcrum portion. it can.

[0026] According to the above-mentioned aerosol container cap, since the fulcrum portion that acts as a fulcrum for rotating the button during normal use of the aerosol container and acts to push down the valve stem is provided. In addition to the advantage that it is easy to press, the above-mentioned cap for an air container has an advantage.

[0027] Further, the aerosol container cap according to the present invention may be configured such that, in the aerosol container cap, the injection opening has a concave shape opened to an upper end side of the cap body.

[0028] According to the above-mentioned aerosol container cap, since both the injection opening and the operation recess of the cap main body are concave shapes opened to the upper end side of the cap main body, the container force aerosol container cap can be simplified. The cap body can be designed so that it can be removed. In the case of this aerosol container cap, near the upper end of the cap body. The container side cap body can be easily removed by holding the side wall between the fingers with fingers on both sides and applying a little force. The cap body can also be easily removed with respect to the container force. By holding it as described above, the fitting portion to the container formed at the lower end of the cap body is opposite to the sandwiched direction, that is, the container. This is because it receives the action of opening outward. In this way, it is easy to remove the container force cap body, so that it is easy to remove the button body force from the button to discharge the contents of the container, and the contents are discharged in the middle. It is easy to stop. In addition, when the aerosol container cap is made of resin and the container is made of metal, when the aerosol injection device is discarded, it is easy to separate and collect the oil and metal. There are advantages

[0029] The aerosol injection device according to the present invention is characterized in that a deviation of the aerosol container cap is attached to an aerosol container containing the contents for injection.

[0030] According to the above-mentioned aerosol injection device, since the container is fitted with either the! / ヽ of the aerosol container cap, the aerosol injection device reflects the advantages of each of the aerosol container caps. . Therefore, when disposing of the aerosol injection device, it is possible to discharge the contents safely without contaminating the surroundings with a simple operation, and there is an aerosol injection device that can easily handle the separation and collection of waste. can get. BEST MODE FOR CARRYING OUT THE INVENTION

[0031] Hereinafter, an aerosol container cap according to an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings used for description, the same or similar parts may be denoted by the same reference numerals, and redundant description may be omitted.

FIGS. 1 to 3 are views showing an aerosol container cap according to Embodiment 1 of the present invention together with an aerosol container, in which FIG. 1 shows a non-use state, and FIG. 2 shows a normal use state (injection). Figure 3 shows the state when the contents in the aerosol container are discharged. 1 to 3, (a) is a perspective view, (b) is a cross-sectional view along the injection direction including the central axis of the aerosol container, (c) includes the central axis of the aerosol container, and (b) FIG. 4 is a cross-sectional view in a plane orthogonal to the shown cross section.

[0033] As shown in FIGS. 1 to 3, the cap 1 for an aerosol container according to Embodiment 1 is a cap. It is composed of a main body 11 and a button 12. An aerosol container (a part of the container is shown in FIGS. 1 to 3; hereinafter, “aerosol container” may be simply abbreviated as “container”) 13 Used by attaching.

[0034] The cap body 11 is substantially cylindrical and has a fitting portion id (see Fig. 1 (c)) for mounting on the container 13 at the lower end. It is designed to be fitted into the tightening portion 13a. Further, the side of the cap body 11 is opposed to the injection opening l lb and the injection opening l ib for allowing the propellant, which is the contents, to pass, and is opened to the upper end 11a side of the cap body 11. An operation recess 11c for receiving a finger when the button is pressed is formed. Further, the cap body 11 is formed between the injection opening l ib and the operation recess 11c along the central axis direction of the container 13, and a button mounting portion (later FIG. 4) is inserted. 15) is formed. Further, the inside of the cap body 11, that is, the area surrounded by the upper portion of the container 13, the side wall of the cap body 11, the ceiling portion, the button 12, etc. is a space.

[0035] When the contents in the container 13 are discharged, the contents may be discharged into an area surrounded by the cap body 11 and the container 13 at that time. The fitting portion 11d can be tightly fitted to the tightening portion 13a of the container 13 (the tightening portion between the body portion of the container 13 and the mauten cap) and can be piled on the injection pressure to maintain the fitting state. It can be configured as follows.

For example, as shown in FIGS. 1 (b) and 1 (c), the button 12 is a valve stem (hereinafter referred to as a stem) in which the upper force of the container 13 protrudes at the center of the lower portion of the button 12. A connecting portion 17 connected to the 16 tip portions is provided. The contents in the container 13 flowing out from the stem 16 are transferred from the nozzle hole 12 a formed in the side wall of the button 12 to the central axis of the container 13 through the tubular flow path formed in the button 12. So that it is sprayed in a substantially right angle direction. The button 12 can be moved along the button mounting portion 15 and can be attached to and detached from the button mounting portion 15.

[0037] It should be noted that since the stem 16 is biased upward, a force to push back upward acts on the button 12 when the stem 16 is pushed down. Therefore, in the non-use state shown in FIG. 1, as shown in FIG. 1 (c), the locking projections 19a, 1 formed on the button 12 The upward movement of the button 12 is constrained by the opening 9b and the upper end portions 18c and 18d of the open or concave protrusion guides 18a and 18b formed on the side wall of the button mounting portion 15 of the cap body 11. (This will be explained later with reference to FIGS. 4 and 5.) However, when the button 12 is pressed, the upper ends of the locking projections 19a and 19b and the projection guides 18a and 18b are not used as long as they do not interfere with the injection of the contents of the container 13. There may be a gap between 18c and 18d. Therefore, in a non-use state, when the button 12 is connected to such an extent that it does not fall off the stem 16, the button 12 is not necessarily locked by the locking projections 19a, 19b! Yeah!

[0038] As shown in FIG. 2, in the case of normal use in which the propellant is injected, the upper surface of the button 12 is pressed and the stem 16 is pressed down. As a result of the operation, the propellant is injected through the nozzle hole 12a along with the injection gas (high pressure gas) in the container 13.

4 and 5 are perspective views individually showing the cap body and the button, FIG. 4 shows the cap body, and FIG. 5 shows the button. Figures 4 (b) and 5 (b) are cross sections taken along the line IVb-IVb 'and Vb-Vb', respectively, including the central axis shown in Figures 4 (a) and 5 (a). It is a figure.

As shown in FIGS. 4 (a) and 4 (b), the cap body 11 has a button mounting portion 15 formed therein, and the button mounting portion 15 is open at the top and bottom. Further, locking protrusions 19a formed on the button 12 are formed on the side wall 15a of the button mounting portion 15 in a direction substantially perpendicular to the direction (content injection direction) connecting the injection opening l ib and the operation recess 11c. Protrusion guides 18a and 18b corresponding to 19b are formed. Each of these protrusion guides 18a and 18b is open at the lower end side of the side wall 15a, and has a substantially rectangular shape that is long in the moving direction of the stem 16 (the central axis direction of the container 13). Although FIG. 4 shows an example in which the protrusion guides 18a and 18b are opened, a concave shape (groove shape) that does not necessarily need to be opened may be used.

On the other hand, as shown in FIGS. 5 (a) and 5 (b), the side wall 12b of the button 12 has a position corresponding to the protrusion guides 18a and 18b formed on the side wall 15a of the button mounting portion 15. Locking protrusions 19a and 19b are formed. These locking projections 19a and 19b are fitted into the projection guides 18a and 18b. The locking projections 19a, 19b and the projection guides 18a, 18b are fitted together when not in use, as shown in Fig. 1. In this case, as shown in Fig. 1 (c), the locking projections The upper end surfaces of 19a and 19b face the upper ends of the protrusion guides 18a and 18b. Further, during normal use when the button 12 is pushed down, as shown in FIG. 2 (c), the locking projections 19a and 19b are positioned in the middle of the projection guides 18a and 18b.

As described above, the locking means of the aerosol container cap 1 are the projection guides 18a and 18b formed on the side wall 15a of the button mounting portion 15 of the cap body 11, and the upper ends 18c and 18d of the button 18b. It is constituted by the locking projections 19a and 19b formed on the side wall 12b of the.

[0043] When discharging the contents in the container 13 such as when the aerosol container is discarded, the cap body 11 is first removed from the container 13 and then the button 12 is pulled downward from the button mounting portion 15. Next, the button 12 is turned upside down and the downward force is inserted upward into the button mounting portion 15. In this case, the locking projection 19a of the button 12 is fitted into the projection guide 18b, and the locking projection 19b is fitted into the projection guide 18a. In this manner, the cap body 11 is attached to the container 13 while the button 12 is inserted upside down into the button attachment portion 15, that is, with the top surface T of the button 12 inserted downward (toward the stem 16).

[0044] Fig. 3 shows a state in which the top surface T of the button 12 is inserted downward (toward the stem 16) and the cap body 11 is attached to the container 13, that is, when the contents in the container 13 are discharged. It is shown. In this case, since the stem 16 is urged upward, a force pushing upward is applied to the button 12. On the other hand, in the button 12, the locking protrusions 19a, 19b of the button 12 are locked against the protrusion guides 18a, 18b formed on the side wall of the button mounting portion 15, and the upper ends 18c, 18d of the button 12 are locked. Is restrained. In this state, the locking position is set so that the top surface T of the button 12 pushes down the stem 16, so that the stem 16 is pushed down by the top surface of the button 12. Therefore, the contents in the container 13 are continuously discharged from the stem 16.

At this time, the tip surface force of the stem 16 is in a state of facing the top surface T of the button 12. Therefore, the flow output of the contents discharged from the stem 16 may be obstructed by the top surface T of the button 12. However, as shown in FIGS. 1 to 3, the top surface T of the button 12 is usually inclined so that the operation concave portion 11c side is lowered from the viewpoint of pressing operability with fingers. If the discharged contents are fluid, the discharge of the contents is not likely to be hindered. However, if the fluidity of the discharged contents is low, Since there are cases where the amount of discharge is large, it is more preferable that the structure is such that the discharge of the contents is not hindered.

[0046] The content discharge passage 14 shown in FIGS. 1 (a), 2 (a), and 5 is an example of means for facilitating discharge of the content. A flow path for discharging contents (hereinafter abbreviated as “flow path”) 14 formed on the top surface T of the button 12 is substantially groove-shaped, and the tip of the stem 16 is formed on both side walls of the flow path 14. It comes in contact with the upper end of the. Since the contents discharged from the tip force of the stem 16 are discharged into the flow path 14, the discharge of the contents is not hindered.

[0047] Therefore, by providing the above-described flow path 14, in the case of the aerosol container cap 1 according to Embodiment 1, the discharge of the contents can be greatly improved.

[0048] In addition, an example of a groove-shaped flow path formed on the top surface T of the button 12 is shown as the flow path 14. The flow path for discharging the contents is formed on the top surface T of the button 12. It is not limited to a groove-shaped channel. For example, even if it is a tubular flow channel that opens at a position corresponding to the tip of the stem 16 on the top surface T of the button 12 and passes through the button 12 and opens at a position corresponding to the space in the cap body 11. Good. Further, it may be a protrusion, a recess, or the like that can form a gap between the distal end portion of the stem 16 and the parietal surface T. In this specification, these are collectively referred to as a “flow channel”. In addition to this, the tip of the stem 16 that is not provided with a flow path in the button 12 is cut obliquely, and only the leading edge of the cut portion of the stem 16 is in contact with the top surface T of the button 12. Well ...

As is clear from the state shown in FIG. 3, in the case of the aerosol container cap 1, the stem 16 can be pushed down by the top surface T of the button 12. Therefore, it is easy to push down the tip of the stem 16 to a height lower than the lower end of the injection opening 1 lb or the lower end of the operation recess 1 lc. Therefore, it is possible to easily design a cap that can discharge the contents into the cap body 11 even though it is a one-touch type cap. In other words, since the aerosol container cap 1 has few restrictions on the cap design, the aerosol container cap 1 is a cap that can easily discharge the contents when the aerosol container is discarded. However, it has the advantage of being able to design an aerosol container cap with excellent design.

FIG. 6 is a diagram showing a button 12A according to another embodiment, (a) is a perspective view, and (b) is (a 6 is a cross-sectional view taken along the line VIb-VIb ′ including the central axis shown in FIG. The button 12A has substantially the same form as the button 12 already described, and only the shapes of the locking protrusions 20a and 20b are different from the button 12 as shown in FIG.

That is, the button 12A has a shape in which the upper surface side (the top surface T side) is inclined downward toward the outer side and the lower surface side is substantially orthogonal to the protrusions 20a and 20b force side portion 12b. , Ru In addition, the length 12 between the tips of the protrusions 20a and 20b is slightly longer than the inner diameter of the button mounting part 15.The button 12A can be turned upside down so that it can be pushed downward into the button mounting part 15 from above. It has become. Using the elastic deformation of the side wall 15a of the button mounting part 15 and the protrusions 20a, 20b, etc., when the button 12A is inserted into the button mounting part 15 in the upside down direction, the lower surface of the protrusions 20a, 20b (the top surface T and The opposite surface) is locked by the upper end portions 18d and 18c of the protrusion guide openings 18b and 18a.

[0052] When the contents in the container 13 are discharged, such as when the aerosol container is discarded, the cap body 11 is first removed from the container 13, and the button 12A is withdrawn downward from the button mounting portion 15. Next, the cap body 11 is attached to the container 13, the button 12A is turned upside down, and the button 12A is pushed into the button attaching portion 15. By this operation, the button 12A is attached to the cap body 11 with the stem 16 being pushed down, as in the case of the button 12 shown in FIG.

In this way, in the case of the button 12A, the button 12A can be pushed into the button mounting portion 15 in the upside down direction with the cap body 11 mounted on the container 13. In the case of the button locking means provided with the button 12A, there is an advantage that it is easy to grasp the timing of discharging the contents of the container 13.

FIG. 6 shows an example in which the locking projections 20a and 20b of the button 12A are provided with an inclination. The upper ends of the projection guides 18a and 18b formed on the side wall of the button mounting portion 15 are The shape may be inclined downwardly. Further, by combining the button 12A, the contact portions of the two may be inclined in the same direction.

FIGS. 7 and 8 are diagrams respectively showing a cap body and a button of the aerosol container cap 2 according to Embodiment 2, FIG. 7 shows the cap body, and FIG. 8 shows a button. . Figures 7 (b) and 8 (b) show Vllb-VII including the center line shown in Figures 7 (a) and 8 (a), respectively. b 'cutting line, VHIb VHIb' is a sectional view taken along the cutting line.

The aerosol container cap 2 composed of the cap body 21 and the button 22 shown in FIG. 7 is substantially the same configuration as the aerosol container cap 1 according to the first embodiment. The structure of the locking means for locking the movement to is different. As shown in FIGS. 7A and 7B, the cap body 21 is formed with a button mounting portion 25, and the button mounting portion 25 is open at the top and bottom. Further, locking projections 28a and 28b are formed on the side wall 25a of the button mounting portion 25 in a direction substantially perpendicular to the direction (content injection direction) connecting the injection opening 21b and the operation recess 2lc. Yes.

On the other hand, as shown in FIG. 8, the button 22 has protrusion guides 29a and 29b formed on the side wall 22c in a direction substantially perpendicular to the content injection direction. The positions of the protrusion guides 29a and 29b correspond to the locking protrusions 28a and 28b formed on the side wall 25a of the button mounting portion 25 of the cap body 21. Further, the protrusion guides 29a and 29b are rectangles that are long in the moving direction of the stem 16 (the central axis direction of the button 22), and the upper end portion and the lower end portion are opened. Further, the locking nodes 30a and 30b for locking the movement of the button 22 are respectively provided at the intermediate portions of the stem 16 in the moving direction.

[0058] When the aerosol container cap 2 is set in a non-use or normal use state, the button 22 is Inserted in button mounting part 25. In this case, the locking projections 28 a and 28 b of the button mounting portion 25 are fitted into the projection guides 29 a and 29 b of the button 22! When the aerosol container cap 2 is attached to the container 13 in this state, the lower surfaces of the locking projections 28a and 28b of the cap body 21 and the upper surfaces of the locking nodes 30a and 30b of the button 22 (the top surface T side). ) Comes into contact with each other, and the upward movement of the button 22 is restricted. In this state, the button 22 is mounted without falling off the cap body 21, and the stem 16 can be pressed.

[0059] When the aerosol container cap 2 is set to the state when the contents are discharged, the container body 13 also removes the cap body 21 and pulls out the button 22 from below the button mounting portion 25 of the cap body 21. . Next, insert the button 22 into the button mounting part 25 from below the button mounting part 25 with the button 22 turned upside down, that is, with the top surface T of the button 22 facing downward. . When the aerosol container cap 2 is attached to the container 13 in this state, the lower surface of the locking projections 28a and 28b of the cap body 21 and the lower surface of the locking nodes 30a and 30b of the button 22 (on the opposite side of the parietal surface) The upper surface of the button 22 is locked and the upward movement of the button 22 is locked, and the stem 16 is pushed down by the top surface of the button 22 so that the contents in the container 13 are continuously discharged from the stem 16. become.

[0060] Although not shown, in the case of the aerosol container cap 2, the same means as the locking projections 20a, 20b of the button 12A shown in FIG. 6 can be used. In other words, the upper surfaces of the locking projections 28a and 28b formed on the side wall 25a of the button mounting portion 25 shown in FIG. 7 may be inclined downward toward the inside. In addition, the upper surfaces (the top surface T side) of the locking bars 30a and 30b of the button 22 can be inclined downward toward the outside. With this configuration, as with the button 12A, with the cap body 21 mounted on the container 13, the button is turned upside down and the button is inserted into the button mounting portion 25 with upward force. Can do.

FIGS. 9 to 11 are diagrams showing the aerosol container cap according to the third embodiment together with the aerosol container. FIG. 9 shows a state when not in use, and FIG. 10 shows a state during normal use (during injection). State, Fig. 11 shows the state when the contents in the aerosol container are discharged. 9 to 11, (a) is a perspective view, (b) is a plan view seen from above, and (c) is IXc IXc ', Xc-Xc', XIc- It is sectional drawing in a XIc 'cutting line.

[0062] The aerosol container cap 3 according to the third embodiment includes a cap body 31 and a button 32 as shown in Fig. 9 to L1. The cap body 31 is substantially cylindrical and has a fitting portion 31d (see FIG. 9 (c)) to be attached to the container 13 at the lower end, and the fitting portion 31d is a tightening portion of the container 13. It is fitted to 13a. In addition, the side of the cap body 31 receives a finger when the button opening toward the upper end 31a is pressed toward the injection opening 31b and the injection opening 31b for passing the propellant as the contents. A recess 31c for operation is formed. Further, the cap body 31 is formed with a button mounting portion 35 (described later with reference to FIG. 12) to which the button 32 is mounted between the ejection opening 31b and the operation recess 31c.

[0063] The button 32 includes a nozzle for injecting the contents in the container 13 from the nozzle hole 32a, and the container 13 A stem pressing portion 37 is provided in contact with the distal end portion of the stem 16 protruding from the upper portion and guiding the contents in the container 13 to the nozzle hole 32a. Further, a normal use pressing portion 32 h is provided on the upper surface of the stem pressing portion 37 on the operation recess 31 c side.

As shown in FIGS. 9 to 11, the button 32 is assembled into the button mounting portion 35 of the cap body 31. Thus, when the cap 3 composed of the cap body 31 and the button 32 is attached to the container 13 with the stem pressing portion 37 of the button 32 in contact with the stem, the nozzle hole 32a side with respect to the stem 16 In addition, during normal use of the aerosol container, when the button 32 is pushed down, a fulcrum portion A is formed which acts as a pivotal fulcrum for the button 32 and acts to push down the stem 16.

FIGS. 12 and 13 are perspective views individually showing the cap body and the button, FIG. 12 shows the cap body, and FIG. 13 shows the button. FIG. 12 and FIG. 13 are views seen from the upper left side.

[0066] As shown in FIG. 12, the cap body 31 is formed with a button mounting portion 35, and the button mounting portion 35 has an open bottom. Also, across the position corresponding to the stem 16, on the side wall 35d side, the projection guides 38a, 38b corresponding to the projections 39a, 39b formed on the button 32, and on the opposite side wall, the projections 39c, Projection guides corresponding to 39d (38c and 38d, not shown) are formed. Each of these projection guides 38a to 38d has a substantially rectangular shape or an inverted V-shape with the lower end of the side wall opened.

On the other hand, as shown in FIG. 13, the button 32 has projections 39a, 39b on the side wall 32d side at a position corresponding to the stem 16, that is, with the stem pressing portion 37 shown in FIGS. The protrusions 39c and 39d are formed on the side wall 32 eftlj! Projection 39a, 39b, 39c, 39di each cap body 3 U Projection guides 38a, 38b, 38c, 38d formed by a normal fit of container 13 with projections 39a, 39c and projection guides 38a, 38c In use, a fulcrum A (see Fig. 10 (c)) is configured to act so that the stem 16 is pushed down. When attaching the button 32 to the button mounting part 35 of the cap body 31, the button 32 should also be inserted with the downward force of the button mounting part 35 upwards.

The operation of the fulcrum portion A will be described with reference to FIGS. 9 to 11 as follows. In the non-use state shown in FIG. 9, the stem pressing portion 37 of the button 32 is in contact with the stem 16. this The stem 16 is biased so as to be pushed up against the push-down by a spring included in a valve mechanism provided in the container 13. Accordingly, when not in use as shown in FIG. 9, the stem 16 slightly pushes up the button 32 with the stem pressing portion 37, and the upward force acting on the protrusions 39a to 39d of the button 32 is the protrusion guide formed on the cap body 31. It is in a state of being restrained by 38a to 38d.

[0069] During normal use, that is, when the propellant is injected, the normal use pressing portion 32h of the button 32 is pushed down by the user as shown in FIG. Therefore, the fulcrum portion A force button 32 on the nozzle hole 32 a side with respect to the stem 16 serves as a fulcrum of rotation, and the stem pressing portion 37 pushes down the stem 16.

[0070] When the contents in the container 13 are discharged, such as when the aerosol container is discarded, the cap body 31 is first removed from the container 13, and the button 32 is further pulled downward from the button mounting portion 35. Next, the button 32 is turned upside down and the downward force is inserted upward into the button mounting portion 35. In this case, on the side wall 35d side of the button mounting portion 35, the locking projection 39c of the button 32 is fitted into the projection guide 38a, and the locking projection 39d is fitted into the projection guide 38b. The other side wall is similarly fitted. In this way, the cap body 31 is attached to the container 13 while the button 32 is inserted upside down in the button attachment portion 35, that is, with the top surface T of the button 32 inserted downward (toward the stem 16).

[0071] The state in which the top surface T of the button 32 is inserted downward (toward the stem 16) and the cap body 31 is attached to the container 13, that is, the state when the contents in the container 13 are discharged is shown in FIG. It is shown. In this case, since the stem 16 is urged upward, the button 32 is pressed upward. On the other hand, in the button 32, the locking protrusions 39a to 39d of the button 32 hit the upper ends of the protrusion guides 38a to 38d formed on the side wall of the button mounting portion 35, and the top surface T of the button 32 balances almost horizontally. It is locked in a state where it is removed, and the upward movement is restricted. In this state, the locking position is set so that the stem 16 is pushed down by the top surface T of the button 32. Therefore, the stem 16 is pushed down by the top surface T of the button 32. Therefore, the contents in the container 13 are continuously discharged from the stem 16.

[0072] Note that the locking means in this case includes a locking portion constituted by the fulcrum portion A and the button 32. This is constituted by auxiliary locking portions formed by the protrusions 39b and 39d and the protrusion guides 38a and 38c of the cap body 31. By these locking portions and auxiliary locking portions, the inclination of the button 32, that is, the posture is maintained so that the contents can be discharged when the stem 16 is pressed by the top surface T of the button. It has become.

[0073] At this time, the tip surface force of the stem 16 faces the top surface T of the button 32. Therefore, the flow output of the contents discharged from the stem 16 may be obstructed by the top surface T of the button 32. It is more preferable that the top surface T is configured so that the discharge of the contents is not hindered because the discharged contents have low fluidity and may have a large discharge amount. The content discharge channel 34 shown in FIGS. 9 (a), 10 (a), and 13 is an example of means for making it easier to discharge the content. The content discharge flow path 34 formed on the top surface T of the button 32 may have almost the same configuration as the flow path 14 of the button 12 according to the first embodiment! Omitted.

FIG. 14 is a perspective view showing an aerosol container cap according to another embodiment, wherein (a) is an entire cap showing a state of discharging contents, (b) is a cap body, (c) Is a button. The aerosol container cap 3A shown in FIG. 14 corresponds to another aspect of the aerosol container cap 3 according to the third embodiment. When the contents are discharged, the aerosol container cap 3A is a button. The difference is that it is used in the reverse direction.

[0075] As shown in Fig. 14 (a), in the case of the aerosol container cap 3A, when discharging the contents, the button 32A is upside down with respect to the button mounting portion 35A, and the nozzle hole 32a is now mounted so that it faces the button operation recess 31c! The configuration of the aerosol container cap 3A is substantially the same as that of the aerosol container cap 3, and therefore detailed description thereof is omitted. However, since the button 32A is mounted in the direction opposite to that when not in use or during normal use (the nozzle hole 32a is on the button operation recess 31c side), the button 32A is attached to the locking protrusions 39a, 39c of the button 32A during ejection Corresponding protrusion guides (FIG. 14 (b) shows only the protrusion guide 38e!).

[0076] Regarding the aerosol container caps 3 and 3A according to Embodiment 3 shown in Figs. 9 to 14, projection guides 38a to 38e are formed on the side walls of the button mounting portions 35 and 35A of the cap bodies 31 and 31A. In the example shown, the locking protrusions 39a to 39d are formed on the side walls of the buttons 32 and 32A. The relationship between the locking projection and the projection guide may be reversed. That is, as shown in the relationship between the cap main body 21 and the button 22 shown in FIGS. 7 and 8, a projection guide can be formed on the side wall of the button, and a projection can be formed on the side wall of the button mounting portion.

[0077] Also, in the aerosol container caps 3 and 3A according to Embodiment 3 shown in FIGS. 9 to 14, as illustrated in FIG. 6, the protrusion of the button 32 is inclined toward the top surface side. It is also possible that the button 32 is turned upside down so that the upward force of the cap body 31 can be attached.

FIG. 15 is a cross-sectional view showing the aerosol container cap 4 according to Embodiment 4, in which (a) is a discharged state of the contents, and (b) is a button and a stem due to an injection pressure higher than a dangerous value. A state in which there is a gap between the tip portion and (c) shows an enlarged button.

[0079] This aerosol container cap 4 is different from that of the first embodiment in the structure of the protrusions on the button 42, and the cap body 11 and other structures are the same. FIG. 15 (a) shows the state when the contents are discharged, and corresponds to the state shown in FIG. 3 (c) in the first embodiment. That is, the stem 16 is pushed into the contents discharge state by the button 42. On the other hand, FIG. 15 (b) shows a state where the button 42 is lifted by the injection pressure exceeding the danger value, and a gap is formed between the tip of the stem 16 and the top surface T of the button 42.

[0080] As shown in FIG. 15 (b), in order to create the gap as described above when the injection pressure is higher than the dangerous value, the locking protrusion is formed on the side wall 12b of the button 42. 42a and 42b have been added.

[0081] As described above, as shown in FIG. 15 (a), when the button 42 is pushed down to the contents discharge side, the stem 16 is pushed in and the ejected contents are placed on the side wall of the button mounting portion 15. Through the formed openings 18a and 18b (see FIG. 4), the cap body 11 and the container 13 are discharged to the area surrounded by the upper part. At this time, if the temperature in the container 13 is abnormally high due to the influence of direct sunlight or storage at a high temperature, there is the following danger. That is, as the vapor pressure in the container rises, the contents are rapidly ejected from the stem 16. As a result, a strong injection reaction force acts on the aerosol container 13. As a result, there is a possibility that the stem 16 is pressed and the V, button 42 is blown together with the cap body 11 or the aerosol container 13 is blown by the repulsive force of the injection. In particular, in the structure of the above embodiment, the contents flow into the cap body 11 through the openings 18a and 18b (see FIG. 4) formed in the side wall of the button mounting portion 15, and thus the container 13 It accumulates in the space between the top of the cap and the cap body 11 and suddenly generates high pressure. Under this circumstance, if the button 42 force locking projections 19a and 19b and the upper ends 18c and 18d of the projection guides 18a and 18b are firmly held (see Fig. 4), the container 13 The cap body 1 may fly off as much as possible, or the cap body 11 may fly, which is extremely dangerous.

On the other hand, in the case of Embodiment 4 shown in FIG. 15, another side wall 12b of the button 42 is provided on the lower part of the locking projections 19a and 19b (on the side opposite to the top surface T). Locking protrusions 42a and 42b are formed. Further, the locking protrusions 42a and 42b have a shape in which the protrusions on the locking protrusions 19a and 19b side (the top surface T side) are greatly inclined downward toward the inside. As shown in Fig. 15 (a), when the contents are discharged, the button 42 is mounted on the button mounting portion 15 in the upside down direction, and the fitting portion id of the cap body 11 is the tightening portion of the container 13. It is fitted to 13a. For this purpose, the locking projections 42a, 42b are locked by the upper ends 18c, 18d of the projection guides 18a, 18b in the cap body 11, the stem 16 is pushed in, and the contents are discharged.

[0084] If the injection pressure from the stem 16 exceeds the critical value during the discharge of the contents, the locking protrusions 42a, 42b and the protrusion guides 18a, 18b (details) 4), the locking projections 42a and 42b come out above the upper ends 18c and 18d of the projection guides 18a and 18b. The button 42 is locked by locking protrusions 19a and 19b located below the locking protrusions 42a and 42b (the top surface T side) and upper ends 18c and 18d of the protrusion guides 18a and 18b. . In this state, the pushing state of the stem 16 is released, and the discharge of the contents stops. This ensures safety when discharging.

In FIG. 15, the force-engaging protrusions 42a and 42b, which show an example in which the engaging protrusions 42a and 42b are provided separately from the engaging protrusions 19a and 19b, can be omitted. In this case, the shape of the locking protrusions 19a and 19b may be the same as that of the locking protrusions 42a and 42b. In this case, if the injection pressure from the stem 16 exceeds the dangerous value when the contents are discharged, the button is released from the cap body 11. Force that may fall off At that time, the stem 16 is released from the pressing state force, so that the discharge of the contents is stopped. Therefore, the possibility that the contents will be scattered around is small, so that the safety when discharging the contents can be ensured.

FIG. 16 is a cross-sectional view of the aerosol container cap according to the fifth embodiment, together with the aerosol container, along the injection direction including the central axis of the aerosol container, and (a) is a discharged state of the contents, ( b) shows a state where a gap is created between the button and the stem tip due to the injection pressure exceeding the critical value. FIG. 17 is a perspective view showing a cap body and a button of the aerosol container cap shown in FIG. 16, where (a) shows the cap body and (b) shows the button.

[0087] This aerosol container cap 5 is different from that of Embodiment 3 in the structure of the protrusion receiving part of the button mounting part 35 in the cap body 51 and the structure of the protrusion in the button 52, and the other structures are the same. It is. FIG. 16 (a) shows a state when the contents are discharged, and corresponds to the state shown in FIG. 11 (c) in the third embodiment. That is, the stem 16 is pushed in by the button 52. On the other hand, FIG. 16 (b) shows a state where the button 52 is raised by the injection pressure exceeding the danger value, and a gap is generated between the tip end portion of the stem 16 and the top surface T of the button 52.

[0088] As shown in FIG. 16 (b), the protrusion receiving portion and the button 52 in the button mounting portion 35 are provided in order to generate the gap as described above when the injection pressure exceeds the dangerous value. The shape of the protrusion has been partially changed. That is, as shown in FIG. 17, the protrusion receiving portions 38a and 38b (FIG. 17 (FIG. 17 (a)) are provided on the side walls (only the side wall 35e is shown in FIG. In (a), another protrusion receiving portion 38e, 38f is formed on the upper portion of the protrusion receiving wall 38a, 38b on the wall J wall 35e. In addition, protrusions 39c 'and 39d' formed on the side walls on both sides of the button 52 (FIG. 17 (b) shows only the side wall 32e) (FIG. 17 (b) shows the side wall 32e Only the protrusions 39c 'and 39d' are shown in a shape in which the lower side is inclined inward, that is, the shape in which the upper side protrudes.

[0089] As described above, as shown in FIG. 11 (c), when the button 32 is pushed down to the contents discharge state, the stem 16 is pushed in and the ejected contents are formed on the side wall of the button mounting portion 15. On top of cap body 31 and container 13 through openings 18a, 18b (see Fig. 4) formed in It is discharged into the enclosed area. At this time, if the temperature in the container 13 is abnormally high due to the influence of direct sunlight or storage at a high temperature, there is the following danger. That is, as the steam pressure in the container rises, the contents are rapidly ejected from the stem 16. As a result, a strong jet reaction force acts on the aerosol container 13. As a result, the button 31 against which the stem 16 is pressed may be blown together with the cap body, or the aerosol container 13 may fly due to the repulsive force of the injection.

[0090] In particular, in the structure of the above embodiment, the contents flow into the cap body 31 through the openings 18a and 18b (see Fig. 4) formed in the side wall of the button mounting portion 15. 1 It accumulates in the space between the top of 3 and the cap body 31, and suddenly generates high pressure. Under this circumstance, if the button 32 is firmly held by the projections 39c, 39d and the projection receiving portions 38c, 38d, etc., the container 13 may come off from the cap body 31 due to sudden high pressure, The body 31 may fly off, which is extremely dangerous.

[0091] On the other hand, according to the fifth embodiment shown in FIGS. 16 and 17, on the side wall (eg, 35e) of the button mounting portion 35 of the cap body 51, the protrusion receiving portion (eg, 38a, 38b) is provided. ), Another protrusion receiving portion (for example, 38e, 38f) is formed. Further, the protrusion for locking the button 52 (for example, 39c ′, 39d ′) has a shape in which the overhang on the upper side (the top surface T side) is greatly inclined inward as the lower side. Therefore, if the spray pressure from the stem 16 exceeds the dangerous value during the discharge of the contents, the locking projections (e.g. 39c ', 39d') and the projection receiving parts (e.g. 38a, 38b) are positioned. As a result, a locking projection (eg, 39c ', 39d') comes out of the projection receiving portion (eg, 38a, 38b) and the upper projection receiving portion ( For example, it fits in 38e, 38f), the pushing state of the stem 16 is released, and the discharge of the contents stops. This ensures safety when discharging.

FIGS. 16 and 17 show an example in which another projection receiving portion (eg, 38e, 38f) is provided on the upper portion of the projection receiving portion (eg, 38a, 38b). For example, 38e and 38f) can be omitted. In that case, if the button 52 is detached from the protrusion receiving portion (for example, 38a, 38b), the force that may drop off from the cap body 51. At that time, the stem 16 is pressed and the force is released. The discharge is in a stopped state. Therefore, it is unlikely that the contents will scatter around, so ensure safety when discharging the contents. be able to.

In Embodiments 4 and 5, the injection pressure at which the locking protrusions of the buttons 42 and 52 come out of the protrusion receiving portion, that is, the critical value of the injection pressure, is the amount of discharge from the stem 16, It is determined in consideration of the weight of the aerosol container, the fitting strength between the fitting part id and the tightening part 13a, the force with which the user holds the air container and pushes the stem. In addition, the injection pressure can be replaced with a force (injection force) acting between the aerosol container and the cap in accordance with the injection at the time of discharge, and is determined from the following viewpoint. That is, the injection force corresponding to the danger value is determined so as to satisfy the following (a) and (b) or (a) and (c).

(a) It is larger than the force required to push the stem to discharge the contents.

(b) Less than the force required to remove the coupling between the cap body and the button.
