JP 2002-12276 A JP 2001-19066 A

  Currently, aerosol products that are no longer needed are collected as non-flammable garbage by consumers in a state where the aerosol composition (hereinafter referred to as the contents) does not remain in the container (empty state). For this reason, aerosol products are provided with cautions and labels so that they are discarded after being used up. However, the container may still be discarded with the contents remaining inside. In this way, when the aerosol product with the contents remaining is collected with a packer car that compresses and collects garbage, a hole is opened in the aerosol container with a nail that compresses garbage, the contents are released into the car, static electricity, sparks, etc. There is a risk of catching fire from other fire sources. For this reason, various means for safely discharging the entire contents remaining in the aerosol product when the aerosol product is no longer needed have been studied.

  For example, as in JP-A-2000-191062, JP-A-2002-53187, JP-A-2001-180773, etc., a discharge process using a cap, JP-A-2004-123167, etc. Form for discharging using a push button, Form for discharging using a push button and a cap, such as Japanese Utility Model Publication No. 6-3823, Japanese Patent Laid-Open No. 2000-191060, Japanese Patent Laid-Open No. 2001-301853 , Such as JP 2002-193362 A, JP 2003-12061 A, etc., a discharge process using a push button and a shoulder cover, JP 2001-12695 A, JP 2003-26263 A, etc. As described above, there are a form in which the shoulder cover is used for the discharge process, and a form in which the shoulder cover and the cap are used for the discharge process, such as Japanese Utility Model Publication No. 5-35102 and Japanese Patent Application Laid-Open No. 2001-2154.

  Each discharge means has a special shape to fix the push button in the pushed down position, the shape of the injection member and protection member is limited, the design is limited, and it takes time and effort to manufacture is there. Furthermore, since a dedicated discharging means is used, it is necessary to design for each manufacturer or each product, which takes time and effort.

  On the other hand, there is a waste gas treatment valve button that is directly attached to an aerosol valve (Patent Document 1). This waste gas processing valve button has a bottomed cylindrical shape, and a fixing portion is provided inside the opening for fixing to the valve seat housing portion of the aerosol valve. When the aerosol product is no longer needed, the waste gas processing valve button first removes the injection member from the valve and attaches it to the valve seat housing portion from above the stem of the aerosol product. As a result, the stem is pushed down at the inner bottom of the waste gas treatment valve button to open the valve, and this state is maintained.

  There is also a gas venting tool that is attached to the crimp portion of the aerosol valve (Patent Document 2). This degassing tool includes a cylindrical outer peripheral wall and an intermediate wall that is passed into the outer peripheral wall, and a push rod for opening the valve is provided at the center of the intermediate wall. Then, when the aerosol product is no longer needed, this degassing tool first removes the injection member from the valve, and attaches the surface of the aerosol product with the push rod of the degassing tool facing the valve side. . At this time, by engaging an annular protrusion provided on the outer surface of the outer peripheral wall with the crimp portion, the push rod opens the female valve and maintains it in this state.

  Any of the above-disclosed aerosol products can be used as a common discharge device regardless of the shape of the injection member because it is directly attached to the aerosol valve. However, once attached to the valve, the shape is difficult to remove, and the discharge cannot be stopped halfway. Therefore, even if an accident occurs, such as when an aerosol product falls during the discharge process or when the contents being discharged are ignited, it is not possible to take immediate action. The present invention is accommodated in the injection member in the normal use state and does not affect the appearance, and does not accidentally become a content discharge state by extension of the normal use method. In the state of content discharge, the aerosol valve and the injection member It is possible to hold the injection member with the aerosol valve open, and to use it as a common discharge device, and it is equipped with a content discharge device that can interrupt discharge in the middle of content discharge The purpose is to provide aerosol products.

An aerosol product according to the present invention (Claim 1) includes a pressure-resistant container and an aerosol container fixed to an opening of the pressure-resistant container, an aerosol composition filled in the aerosol container, and the aerosol valve An injection member attached to the inside, and a contents discharger capable of holding the injection member in a state where the aerosol valve is opened, and the aerosol valve is formed from an upper bottom cylindrical housing holding portion and a lower end of the housing holding portion. A mounting cup comprising a disc portion extending outward in the horizontal direction, a cylindrical side wall portion rising upward from an outer edge of the disc portion, and a curl portion formed at the upper end of the side wall portion; A cylindrical outer portion having an upper base, and a cylindrical passage portion formed inside the outer portion for guiding the aerosol composition to the injection hole And wherein the content discharge member is in normal use, is therefore on the inner surface or the passage portion of the outer part holding the injection member, in a state the contents discharged in conjunction with a portion of the injection member and the aerosol valve aerosol The injection member is held with the valve opened.

  Here, the state of normal use of the aerosol product of the present invention refers to a state from when the aerosol product is manufactured until it becomes unnecessary, such as a state in which the aerosol product can be normally used and a state in which it is stored. In addition, the state of content discharge means a state in which the aerosol product is used or unnecessary, and the content of the aerosol composition is discharged immediately before disposal.

A second aspect of the aerosol products of the present invention is a aerosol product and a shoulder cover to be attached to e azole container contents discharge device is connected in a detachable shoulder cover state in normal use In the state of discharging the contents, the spray member is separated from the shoulder cover and connected to a part of the spray member and the aerosol valve to hold the spray member in a state where the aerosol valve is opened (claim 2 ).

Further, as the aerosol product of the present invention, when the contents are discharged, the contents discharger holds the injection member in a state where the outer portion of the injection member or the passage portion and the housing holding portion are connected to open the aerosol valve. Preferred (Claim 3 ). And as a thing which connects a contents discharge tool and a housing holding part in the state of contents discharge, an annular recess is formed in the lower part outer periphery of a housing holding part of an aerosol product, and one opening part of the above contents discharge tool The thing in which the engagement protrusion engaged with the recessed part is formed is mentioned (Claim 4 ).

The content discharger of the present invention (Claim 5 ) is a content discharger used for the aerosol product of the present invention, and has a cylindrical form with openings at both ends, and an injection member at one opening. A connecting means for connecting is provided, and a connecting means for connecting to a part of the aerosol valve is provided in the other opening.

Such a content discharger is provided with a partition wall having an insertion hole into which an aerosol valve stem can be inserted, and is partitioned into a first tube portion and a second tube portion by the partition wall, the first cylindrical portion is connectable with the housing holding part of the aerosol valve, said second cylindrical portion is intended preferably be connected to the passage portion of the injection member (claim 6).
Further, the inner diameter of the first tube portion is large enough to accommodate the housing holding portion, and an engagement protrusion protruding inwardly connected to the housing holding portion of the valve is formed in the opening portion of the first tube portion. (Claim 7 ).
Furthermore, it is a content discharger for an aerosol product in which an L-shaped groove comprising a vertical groove and a lateral groove extending from the lower end is formed on the outer peripheral surface of the passage portion of the injection member, and the L You may have an engagement protrusion inserted in a character-shaped groove | channel (Claim 8 ).

Further, the present invention is a content discharge tool comprising an inner peripheral wall, an intermediate wall, and an outer peripheral wall, each having a different diameter, the inner peripheral wall being connectable to a housing holding portion, and the intermediate wall being an outer wall portion. is connectable with the inner peripheral surface, the outer peripheral wall is intended preferably be connected to the lower end outer periphery of the outer portion (claim 9). Further, it is used for aerosol products having a shoulder cover attached to an aerosol container, and has an inner peripheral wall and an outer peripheral wall having different diameters, and the inner peripheral wall can be connected to a housing holding portion. , a connecting portion separable and shoulder cover the outer periphery of the outer peripheral wall, is preferred the inner periphery of the outer peripheral wall is connectable to the lower end outer periphery of the outer portion (claim 10).

For aerosol product of the present invention (claim 1), which is normally the outer portion inner surface of the member morphism contents discharge device is injection in the state of use, or thus holding the passage formed inside of the outer shell, The contents discharger itself does not affect the appearance of the aerosol product. Therefore, the shape of the injection member can be freely designed, and a product that does not differ in appearance from a conventional aerosol product that does not include a discharge tool can be manufactured. In addition, when the operation of discharging the contents is performed when the aerosol product is no longer needed, it is usual to remove the injection member from the stem, take out the content discharge device, and connect the content discharge device to the injection member and the aerosol valve. By performing two or more operations different from the injection operation, the injection member can be held in a state where the aerosol valve is opened. Therefore, the extension of the operation in the normal use state does not cause the contents to be discharged. Further, in the state of content discharge, the injection member is connected to the aerosol valve via the content discharge device, and a part of the injection member is used as a part of a protective member such as a shoulder cover or a cap like a conventional discharge mechanism. Since the injection member is not fixed by the shoulder cover, etc., such as engaging, it is easy to remove the injection member because it is not covered by the member to be fixed, and the injection stops immediately even during the discharge process Even if an accident occurs, such as when the product falls, it can be dealt with immediately.

In addition, since the aerosol product of the present invention discharges the contents from the injection hole of the injection member, the consumer can recognize the discharge direction of the contents, and the discharged contents are not applied to the consumer safely. Can be discharged.
Furthermore, the aerosol valve used in the present invention to which the contents discharger is connected when the contents are discharged is a member common to many conventionally known aerosol products, and most of the aerosols are obtained by unifying their shapes and sizes. It can be used as a content discharge tool common to products.

If the medium only discharging device is held in the passage in the interior of the outer portion of the injection member in a state of normal use, the body portion is or small aerosol product diameter of the vessel, a small injection member to reduce the material in consideration of the environment Can also be used . Also, contents discharge device is usually easier if held to the inner surface of the outer portion in the state of use injection member takes the contents discharged tool from the injection member outside the field of view thumping discharge operation. And, in any case where the contents discharger is held in the passage part or the outer part of the injection member, when manufacturing the aerosol product, the contents discharger and the injection member can be handled integrally, so that the same manufacturing as before It can be manufactured by the method.
The second aspect of the aerosol product of the present invention (Claim 2 ) requires the operation of separating the content discharger from the shoulder cover to make the content discharged, and by extending the injection operation from the normal use state. The contents are not discharged. In addition, there is no risk of losing the contents discharge tool under normal use.

Further, in the aerosol product of the present invention, when the contents discharger is in the state of the contents being discharged, the outer part or passage part of the injection member and the housing holding part are connected to maintain the aerosol valve being opened (Claim 3 ). ), The contents discharge state will not be interrupted. Among these, when connecting the passage portion and the housing holding portion, the passage portion of the injection member and the housing holding portion of the aerosol valve are members common to many conventionally known aerosol products, and their shapes and sizes are unified. Thus, it can be used as a content discharger common to most aerosol products regardless of the shape and size of the outer shell portion, injection hole, and injection nozzle of the injection member. Furthermore, if the contents adhere to the contents discharge tool, such as the contents leaking out from the gap between the stem and the stem mounting part of the passage part while the contents are being discharged or ejected, the fitting strength will decrease and the contents will be discharged. This makes it easier for the injection member to come off, but prevents such a drop. In particular, even if the content is highly lubricious, such as silicone and molybdenum, the ejection member does not come off during ejection, and the ejection process can be performed reliably. Furthermore, by making the outer diameters of the passage portion and the housing holding portion substantially the same, the connecting means can be simplified and the connection strength can be increased. Further, when connecting the outer shell and the housing holding part, it is easy to attach the contents discharger to the injection member, the operation for shifting to the contents discharge state is easy, and it is easy to interrupt the contents discharge in the middle.

Further, in such an aerosol product, when a concave portion is formed in an annular shape on the outer periphery of the lower portion of the housing holding portion, and an engagement protrusion that engages with the concave portion is formed in one opening portion of the content discharge tool, Since the housing holding portion and the content discharger are strongly engaged, the operation is not interrupted during the content discharge. The aerosol composition can be discharged to the end (claim 4 ).

Since the content discharger of the present invention has a connecting means for connecting to the injection member in one opening and a connecting means for connecting to a part of the aerosol valve in the other opening, the above-mentioned aerosol product (Claim 5 ).

Further, in the case of such a content discharger having a partition wall having an insertion hole for inserting a stem therein, the content discharger is held in the passage part of the injection member when the injection member is manufactured. In this state, it can be delivered from the manufacturer of the injection member to the manufacturer of the aerosol and put into the production line as it is.
In the case of normal use, the contents discharger holds the first tube part in the passage part of the injection member. However, when discharging the contents, the content discharger is detached from the injection member and turned over, The tube portion is connected to the passage portion of the injection member, and the first tube portion is connected to the housing holding portion. For this reason, in the normal use state, the discharge operation is not extended by the extension of the injection operation. Further can be used as a common discharge device regardless the shape of the injection member (claim 6).

In such a content discharger, the inner diameter of the first cylinder part is large enough to accommodate the housing holding part, and the first cylindrical part is engaged with the opening that connects the housing holding part of the valve. When the protrusion is formed, the first cylindrical portion can be connected to the concave portion for holding the annularly formed housing at the lower portion of the housing holding portion when the contents are discharged. It can be used as a common discharge tool (Claim 7 ).

It is a content discharger for an aerosol product in which an L-shaped groove comprising a vertical groove and a lateral groove extending from the lower end is formed on the outer peripheral surface of the passage portion of the injection member, and an L-shaped discharge tool for one opening. When having an engaging projection to be inserted into the groove, when discharging, pull the contents discharger against the passage and turn it at that position to lock the contents discharger so that it cannot move vertically. Is done. In this state, the injection member can be held in a state where the valve is opened by mounting and pushing down the injection member on the valve. That is, it does not take time to remove and remount the contents discharging tool. Also, the contents discharge tool is not lost (claim 8 ).

The content discharge tool of the present invention includes an inner peripheral wall, an intermediate wall, and an outer peripheral wall, each having a different diameter, the inner peripheral wall being connectable to the housing holding portion, and the intermediate wall being connected to the inner peripheral surface of the outer shell portion. When the outer peripheral wall can be connected to the outer periphery of the lower end of the outer shell part (Claim 9 ), the intermediate wall of the contents discharger is connected to the inner peripheral surface of the outer shell part of the injection member in a normal use state. When the contents are discharged, the inner peripheral wall of the contents discharger is connected to the housing holding part, and the outer peripheral wall is connected to the outer periphery of the lower end of the outer part to hold the injection member in the opened state.

It is a contents discharge tool used for aerosol products equipped with a shoulder cover attached to an aerosol container, and has an inner peripheral wall and an outer peripheral wall with different diameters, and the inner peripheral wall can be connected to a housing holding part. , a connecting portion separable and shoulder cover the outer periphery of the outer peripheral wall, contents discharge device the inner periphery of the outer peripheral wall is connectable to the lower end outer periphery of the outer portion (claim 10), in normal use The contents discharger is held by the shoulder cover between the outer part of the injection member and the mounting cup of the aerosol valve, and when the contents are discharged, the inner peripheral wall is connected to the housing holding part, and the inner periphery of the outer peripheral wall is the outer part of the outer part. The injection member is held in a state where the valve housing is opened in connection with the outer periphery of the lower end.

It is side surface sectional drawing of the content discharge tool used for.

  An aerosol product 10 shown in FIG. 1 is filled in an aerosol container 11, an injection member 12 attached to the aerosol container, a cylindrical content discharger 13 held by the injection member 12, and an aerosol container. It consists of aerosol composition (contents) A.

The aerosol container 11 includes a pressure-resistant container 14 and an aerosol valve 15 fixed to the opening 14a of the pressure-resistant container.
The pressure vessel 14 is a conventionally known one, and is formed into a bottomed cylindrical shape having a bottom portion 16 and a cylindrical body portion 17 by squeezing or impacting a metal plate such as aluminum or tinplate, Necking is performed on the upper end of the body to form a shoulder 18, and a bead 19 is formed on the upper end of the shoulder by curling. The bottom portion 16 is formed in a mountain shape that rises in a tapered shape toward the center. Thereby, the pressure resistance of the container with respect to the internal pressure is increased and is not easily deformed. In addition, you may use the thing of other materials which have pressure | voltage resistance, such as a synthetic resin and pressure | voltage resistant glass.

  The aerosol valve 15 includes a metal mounting cup 21 fixed to the opening 14a of the pressure-resistant container 14, a cylindrical synthetic resin housing 22 held at the center of the mounting cup, and a vertical movement within the housing. A synthetic resin stem 24 having a stem hole 23 that is freely housed, a spring 25 that constantly biases the stem upward, a stem rubber 26 that closes the stem hole, and a bottom end of the container body from the lower end of the housing. The dip tube 27 extends. The material of these members is not particularly limited, and may be formed from a metal or a synthetic resin.

The mounting cup 21 includes an upper bottom cylindrical housing holding portion 28 for holding the housing 22, a disc portion 29 extending outward in the horizontal direction from the lower end of the housing holding portion, and a cylinder rising upward from the outer edge of the disc portion. And a curled portion 31 that is crimped and fixed to the bead portion 19 of the pressure vessel formed at the upper end of the side wall portion.
Further, a central hole 32 through which the stem passes is formed in the upper bottom 28a of the housing holding portion, and a plurality of concave portions 33 formed by crimping to hold the housing are annularly formed in the lower portion of the housing holding portion. Is formed.

  The injection member 12 has a truncated conical shape attached to the stem 24 of the aerosol valve. The injection member 12 includes a cylindrical outer portion 34 having an upper base 34a and a cylindrical passage portion 35 formed therein. Become. A horizontal passage portion 36 extending horizontally is formed in the upper portion of the passage portion 35, and an injection nozzle 37 a having an injection hole 37 is inserted into an end portion of the horizontal passage portion 36. A stem mounting portion 38 for inserting the stem of the aerosol valve is formed at the lower end of the passage portion 35. That is, the injection hole 37 and the stem mounting portion 38 communicate with each other via the passage portion 35 and the lateral passage portion 36. Further, a flange 39 is formed on the outer periphery of the lower end of the passage portion 35. The outer diameter of the passage portion 35 is smaller than the outer diameter of the housing holding portion 28, and the outer diameter of the flange 39 is formed to be approximately the same as the outer diameter of the housing holding portion 28.

  As shown in FIG. 2a, the cylindrical content discharger 13 is provided with a partition wall 42 having a stem insertion hole 41 into which the stem 24 can be inserted. It is divided into one cylinder part 43 and a lower second cylinder part 44.

  The first cylindrical portion 43 is a portion that is attached to the passage portion 35 of the injection member in a normal use state, and is a portion that is attached to the housing holding portion 28 in the state of discharging the contents (see FIGS. 2A and 2B). The housing holding portion 28 is formed in a size that can be inserted. In other words, the inner diameter of the first cylindrical portion 43 is larger than the outer diameter of the housing holding portion 28, and the depth of the first cylindrical portion 43 is formed deeper than the length from the upper bottom 28 a of the housing holding portion to the concave portion 33. Further, an engagement protrusion 45 a that protrudes inward and engages with the recess 33 of the housing holding portion is formed in the opening of the first tube portion 43. The inner diameter of the engagement protrusion 45a is formed to be slightly smaller than the outer diameter of the passage portion 35 of the injection member.

  That is, in a normal use state in which the passage portion 35 is inserted into the first tube portion 43, the engagement protrusion 45a is frictionally fitted to the outer surface of the passage portion 35, and the contents discharger 13 is held in the passage portion of the injection member. Thus, the content discharger 13 is not separated from the injection member. Further, in the state of the content discharge in which the housing holding portion 28 is inserted into the first tube portion, the engaging protrusion 45a and the recessed portion 33 are strongly engaged.

  The second cylindrical portion 44 is a portion that is left unattended during normal use, and is a portion that is attached to the passage portion 35 of the injection member in a state of content discharge, and has an inner diameter that is the same as the first cylindrical portion 43 and has a depth thereof. Is shallower than the first tube portion 43 and is formed so as to accommodate the flange 39 of the injection member. In addition, an engagement protrusion 45 b that protrudes inward and engages with the flange 39 of the injection member is formed in the opening of the second cylindrical portion 44. As a result, in the state of content discharge, the engagement protrusion 45b and the flange 39 are strongly engaged, and the content leaks out from the gap between the stem and the stem mounting portion of the passage portion during content discharge, and adheres to the content discharge tool. The friction fitting strength between the injection member and the content discharger in the state of content discharge is prevented from being lowered and removed.

In this way, the contents discharger 13 is held in the passage part of the injection member in a normal use state, and in the state of the contents discharger, the passage part of the injection member and the housing holding part are connected to open the aerosol valve. The injection member is held. Therefore, the loss of the contents discharge tool in the normal use state is prevented. In addition, the contents discharge state is not interrupted.
Such a content discharger 13 is molded using a synthetic resin such as polyamide, polyacetal, or polyester. However, you may shape | mold with metals, such as aluminum and tinplate.

  As shown in FIG. 2a, the aerosol product provided with the contents discharger 13 of the present invention has a passage part 35 of the injection member inserted into the first tube part 43 of the contents discharger as shown in FIG. A stem 24 is inserted into 41 and attached to the aerosol container 11. Further, the content discharger 13 is held by the engagement projection 45a of the first tube portion engaging with the passage portion 35 of the injection member so that the partition wall 42 of the content discharger comes into contact with the flange 39 of the injection member. At this time, a gap S larger than the operation stroke of the valve is provided between the lower end of the second cylindrical portion 44 and the upper bottom 28a of the housing holding portion so that the injection member 12 can be pushed down. The aerosol product 10 configured as described above performs an injection operation of pushing down the top surface (upper base 34a) of the injection member with an index finger or the like, whereby the stem 24 is pressed down and the stem hole 23 is released from the stem rubber 26. The inside of the aerosol container communicates with the atmosphere, and the content A inside the aerosol container is ejected from the injection hole 37 through the stem hole 23 through the passage portion 35 in the injection member.

  On the other hand, in the case where the aerosol product is no longer needed and the contents remaining in the aerosol container are discharged, the injection member 12 is first removed from the stem 24 together with the content discharger 13, and the content discharger 13 is removed from the passage part 35 and flange 39 of the injection member. Remove from. Next, the contents discharger 13 is turned upside down to connect the second tube part 44 of the contents discharger and the passage part 35 of the injection member. At this time, the flange 39 of the injection member fits between the engagement protrusion 45b of the second cylinder portion and the partition wall 42. That is, the flange 39 is held in the second cylinder portion 44, and the engagement protrusion 45 b of the second cylinder portion engages with the upper end of the flange 39.

  Thus, after connecting the injection member 12 and the content discharge tool 13 again, the injection member 12 which connected this content discharge tool 13 is again attached to a stem. At this time, the first tube portion 43 of the content discharger is configured to cover the housing holding portion 28. And the injection member 12 is pushed down until the engagement protrusion 45a of a 1st cylinder part engages with the cyclic | annular recessed part 33 of a housing holding part (a state of a content discharge | emission, refer FIG. 2b). Thereby, the injection member 12 will be hold | maintained in the position where the aerosol valve | bulb 15 is open | released, and all the contents A which remain | survive in an aerosol container can be discharged | emitted.

  In the aerosol product 10, the injection member is removed from the stem, the content discharger 13 is once removed from the injection member 12, the content discharger 13 is inverted and reconnected to the injection member 12, and the injection member 12 is again connected to the aerosol valve 15. Since the contents cannot be discharged unless it is attached to the battery, there is no risk of the contents being discharged accidentally by extending the normal injection operation. Moreover, since the cap or shoulder cover etc. for maintaining the injection member 12 in the pushed down position are not required unlike the conventional content discharge mechanism, the injection member 12 can be easily removed even during the content discharge, The content discharge process can be stopped halfway. Furthermore, since the contents are discharged from the injection hole of the injection member, the consumer can safely operate so that the discharged contents are not covered. Since the contents discharger 13 is connected to a passage portion 35 that is a common member of the injection member 12 and a housing holding portion 28 that is a member common to the aerosol valve, the content discharge tool 13 is related to the types of the injection member 12 and the aerosol valve 15. It can be used for most aerosol products and does not affect the appearance of those aerosol products.

  In general, aerosol products are collected as recyclable waste after discharging the entire contents of the aerosol container, but if the contents of the contents discharger and the aerosol container are different, the contents discharger is aerosolized to facilitate recycling. It is preferable to provide a mechanism that facilitates removal from the container. For example, as shown in FIG. 3a, by providing a notch 48 formed in the axial direction on the side surfaces of the first tube portion 43 and the second tube portion 44, when the upper portion of the second tube portion 44 is picked up with a finger, The lower part of the 1 cylinder part 43 expands, and it becomes easy to remove the content discharge tool 13. Such a notch 48 also makes it easy to remove the content discharger 13 from the injection member 12 in a normal use state. Further, as shown in FIG. 3b, a flange 49 may be formed at the opening edge of the second cylindrical portion. Thereby, it becomes easy to pick the content discharger 13, and the removal of the content discharger 13 becomes easier.

4 is attached to an injection member 52 that does not include the flange 39 at the lower end of the passage portion 35 of the injection member 12, and includes a first cylindrical portion 53 having a large diameter and a first tube portion 53 having a small diameter. A cylindrical body having an outward appearance composed of two cylindrical portions 54 is formed.
The first cylindrical portion 53 has an inner diameter that is large enough to insert the housing holding portion 28 of the aerosol valve, and includes an engagement protrusion 55 that protrudes inward in the vicinity of the opening 53a. The inner diameter of the second cylindrical portion 54 is smaller than that of the first cylindrical portion 53, and the second cylindrical portion 54 is of a size that can be frictionally connected to the outer periphery of the passage portion 35 of the injection member and fit securely.
Further, the first cylindrical portion 53 is formed with a stepped portion 57 slightly closer to the opening than the partition wall 56. The inner diameter of the stepped portion 57 is the same size as the second cylindrical portion, and the passage portion 35 of the injection member. Frictionally connected to the outer periphery.

Since it is configured in this manner, in the state of normal use (see FIG. 5a), the step portion of the first tube portion is so that the surface of the partition wall 56 on the first tube portion side and the lower end of the passage portion 35 are in contact with each other. 57 and the passage portion 35 of the injection member are frictionally connected to hold the contents discharger 51 on the injection member 52. At this time, a gap is formed between the opening portion 54a of the second cylindrical portion 54 and the upper surface 28a of the housing holding portion 28 to such an extent that the injection member can be operated. For this reason, the contents discharger 51 does not interfere with the normal injection operation.
On the other hand, when the aerosol product is discarded, the injection member is removed from the stem together with the content discharger 51, and the content discharger 51 is removed from the passage part 35 of the injection member. Next, the contents discharge tool 51 is reversed, and the second cylinder part and the passage part 35 of the injection member are frictionally connected so that the partition wall 56 on the surface on the second cylinder part side and the lower end of the passage part 35 come into contact with each other. The tool 51 is held by the injection member 52. Then, the injection member 52 is mounted again on the valve stem, and further, the injection member 52 is pushed down until the engagement protrusion of the first cylindrical portion 53 engages with the recess 33 of the housing holding portion (the state of content discharge, See FIG. 5b). Thereby, the entire content remaining in the aerosol container can be discharged.
Further, the content discharger 51 may be provided with a ring 59 connected by four legs 58 so as to be easily taken out from the injection member as shown in FIG. 4b. The leg 58 and the ring 59 may be cut out so as to be easily used as a content discharger after the content discharger is taken out from the injection member.

  The content discharger 61 in FIG. 6 a is formed with a protrusion 62 that faces the inner peripheral edge of the opening of the second tube portion 44. In addition, the injection member 63 to which the content discharger 61 is attached has a vertical groove 64 having a width the same as that of the projection 62 extending in the vertical direction at the lower end of the passage portion 35, and horizontally extending from the upper end portion of the vertical groove. It is formed so as to face the lateral groove 65 extending in the direction. Other configurations are substantially the same as those of the content discharge tool 51 and the injection member 52 of FIG.

  Since it is comprised in this way, when discarding an aerosol product, as shown to FIG. 6b, the injection member 63 is removed from a stem with the content discharge tool 61, and the content discharge tool 61 is removed from the channel | path part 35 of an injection member. Next, the contents discharger 61 is reversed, and the contents discharger 61 is mounted on the injection member 63 so that the protrusions 62 of the second cylinder part 44 are inserted into the longitudinal grooves 64 of the passage part 35, and the protrusions 62 engage with the lateral grooves 65. When the content discharger 61 is pushed in, the injection member 63 is rotated. Thereby, the content discharger 61 is strongly connected to the injection member 63, and the injection member 63 does not come off the content discharger 61 during the content discharge.

  7A, three engaging protrusions 72 are formed at equal intervals in the opening of the second cylindrical portion 44. And the notch 73 provided along the side surface of the 2nd cylinder part is formed in the both sides of this engagement protrusion. In addition, an annular engagement groove 75 that engages with the engagement protrusion 72 is formed on the side surface of the passage portion 35 in the injection member 74 to which the content discharge tool 71 is mounted. Other configurations are substantially the same as those of the content discharge tool 51 and the injection member 52 of FIG.

  When discarding the aerosol product configured in this way, as shown in FIG. 7b, the injection member 74 is removed from the stem together with the content discharger 71, and the content discharger 71 is removed from the passage part 35 of the injection member. Next, the contents discharging tool 71 is reversed, and the protrusion 72 of the second cylindrical portion 44 and the annular engagement groove 75 of the injection member are engaged. Thereby, the content discharger 71 is strongly connected to the injection member 74, and the injection member 74 does not come off the content discharger 71 during the content discharge.

  In the embodiments so far, the contents discharging tool mounted on the ejection member has been once removed from the ejection member, reversed, remounted and used. However, in the next embodiment, the contents discharging tool can be brought into the state of the contents discharging operation without removing the contents discharging tool from the injection member.

The content discharger 81 in FIG. 8a has a cylindrical shape, and engages with three sliding protrusions 82 formed so as to face the upper end, and the recess 33 of the housing holding part formed in an annular shape at the lower end. And an engaging protrusion 83.
Further, the injection member 84 is formed on the side surface of the passage portion 35 in a horizontal direction at a vertical groove 85 that guides the sliding projection 82 so as to be slidable in the vertical direction, and at a lower end of the vertical groove. A lateral groove 86 is formed to guide the moving projection 82 so that it can slide in the lateral direction. Further, the outer diameter of the passage portion 35 of the injection member is formed to be the same as the outer diameter of the housing holding portion 28. When the outer diameters of the passage part 35 and the housing holding part 28 are different, the content discharger 81 is also convex.

When the aerosol product 80 including the content discharger 81 and the injection member 84 is in a normal use state, the sliding protrusion 82 of the content discharger 81 is located in the vertical groove 85 of the injection member (see FIG. 8b). ). Preferably, it is a dimensional difference in which the inner diameter surface of the sliding projection 82 and the longitudinal groove 85 are frictionally connected, and the sliding projection 82 is preferably held so as to be positioned at the upper end of the longitudinal groove 85.
Next, when the aerosol product 80 is discarded, the ejection member 84 is removed together with the contents discharger 81 from the aerosol product 80. Next, the content discharger 81 is pulled with respect to the ejection member 84 so that the sliding protrusion 82 is positioned at the lower end of the vertical groove 85. In this state, the content discharger 81 is rotated with respect to the ejection member 84 so that the sliding protrusion 82 is positioned in the lateral groove 86. The injection member 84 in this state is attached to the stem again, and the injection member 84 is pushed down. Thereby, the engagement protrusion 83 of the content discharger 81 is engaged with the recess 33 of the housing holding portion, and the aerosol product 80 is in a content discharge state (see FIG. 8c).

  As described above, since the aerosol product 80 cannot be operated to discharge the contents unless the injection member 84 is once removed, the form of the content discharger 81 in the injection member 84 is changed, and the injection member is not attached to the aerosol valve 15 again. There is no risk of accidental content removal due to extended use. Further, similarly to the aerosol product 10 in FIG. 1, the content discharge operation can be stopped halfway. Furthermore, the aerosol container and the aerosol valve of the conventional aerosol product can be used, and the cost can be reduced.

Similarly to the content discharger 81 in FIG. 8, the content discharger 91 shown in FIG. 9a is not removed from the injection member between the normal use state and the content discharge state.
In the cylindrical content discharger 91, three leaf springs 92 projecting inwardly are formed in the upper end opening side by side at equal intervals, and an engaging projection 93 projecting inward is formed in the lower end opening part. .
Further, an L-shaped groove comprising a vertical groove 96a and a horizontal groove 96b extending from the lower end thereof is formed on the outer peripheral surface of the passage portion 95 of the injection member 94 that uses the content discharger 91. Three vertical grooves 96a and three horizontal grooves 96b are formed at equal intervals.

  During normal use of the aerosol product thus configured, the content discharger 91 is disposed such that the leaf spring 92 of the content discharger is disposed at the upper end of the longitudinal groove 96a of the passage portion (see FIG. 9b). Thereby, injection operation can be performed without being influenced by the contents discharging tool 91. Here, the leaf spring 92 of the contents discharger may be a protrusion. By using a leaf spring in this way, it is easy to mount during aerosol product manufacture. Further, the number is not particularly limited as long as the number is two or more.

  Next, in the state of content discharge, the injection member 94 is removed from the aerosol valve, and the content discharge tool 91 is shifted downward along the outer peripheral surface of the passage portion 95 until the leaf spring 92 is located at the lower end of the vertical groove 96a. In this state, the contents discharger 91 is rotated so that the leaf spring 92 is positioned at the end of the lateral groove 96b (see FIG. 9c). Thereby, the content discharge tool 91 is fixed in the up-down direction. In this state, the injection member 94 is mounted on the aerosol valve again so that the housing holding part is inserted from the lower end of the content discharger. Then, by engaging the engagement protrusion 93 of the contents discharger with the annular recess of the housing holding part, the injection member is maintained with the valve opened, and the entire contents remaining in the aerosol container are discharged. It is.
