Description

  The present invention relates to an aerosol product injection member. More specifically, the present invention relates to an injection member that can easily discharge the entire amount remaining in an aerosol container when an aerosol product is no longer needed.

JP 2002-193362 A Japanese Patent Laid-Open No. 9-40045 JP 2001-180773 A

  The aerosol product includes an aerosol container having a pressure-resistant container and an aerosol valve attached to the opening thereof, an injection member attached to the aerosol container, a stock solution containing an active ingredient filled in the aerosol container, and a flammable liquefied gas Or it is comprised from the aerosol composition which consists of propellants, such as compressed gas. Therefore, by operating the spray member of the aerosol product and opening the aerosol valve, the aerosol composition is pushed out by the pressure of the propellant.

Since such aerosol products have an internal pressure of 0.2 to 0.6 MPa at room temperature, disposing of unnecessary aerosol products with their contents left will compress the aerosol products in the garbage collection process. The contents may be discharged into the collection vehicle and cause a fire. For this reason, disposal of aerosol products that are no longer needed is cited as a major social problem.
Currently, aerosol products are provided with cautions and labels so that all the contents are discharged before disposal of the aerosol product and then disposed of as resource waste to encourage users to dispose of the aerosol product safely. .

  However, since it is troublesome to carry out the injection operation until the inside of the container is emptied separately from the purpose of use, the problem has not been solved. In particular, in many aerosol product injection operations, the push button of the injection member is pushed down with a finger. However, it is necessary to continue to press the injection member until the injection is completely completed, which imposes a heavy burden on the user.

Various studies have been made to solve such problems. In Patent Document 1, a plurality of protrusions are formed on the outer peripheral surface, and an injection button (push button) attached to the stem, a central hole portion that exposes the head portion of the injection button, and an annular peripheral wall of the central hole portion. An aerosol container comprising a shoulder cover (cover member) attached to an aerosol container having a deep cutout portion and a shallow cutout portion formed at the lower end and having different depths is disclosed. In the aerosol product configured as described above, the projection of the injection button is inserted into the deep cutout in a state of normal use. Then, the projection is engaged with the shallow notch by pushing down the ejection button to release the projection from the deep cutout and rotating the jet button so that the projection fits into the shallow cutout. Thereby, the shoulder cover holds the push button in a state where the valve is opened.
However, since such a discharge mechanism can be extended by normal use, there is a risk of performing a discharge operation by mistake. In addition, the user can perform a mischievous discharge operation, can continue to inject the contents, and is particularly dangerous when the contents are flammable or have aspiration toxicity.

Further, Patent Document 2 includes a head (push button) having a stem fitting portion that fits with the stem of an aerosol valve, and a cap having a locking bar that can be fitted to the stem fitting portion of the head. An aerosol type liquid ejection container is disclosed. Therefore, the valve can be maintained in an open state by removing the head from the stem, turning it over, attaching the stem fitting portion of the head to the locking rod of the cap, and then attaching the cap to the aerosol container.
However, in this aerosol type liquid injection container, since the valve stem is pushed down on the upper surface of the head, the gas discharge groove is formed on the upper surface, but the contents are not easily discharged.

  Furthermore, as shown in Patent Document 3, the applicant of the present invention is a gas in which an upper surface of a cap is provided with a gas ejection hole that engages with a stem of an aerosol valve and an engagement portion that engages with a bead portion of an aerosol container. An aerosol container cap with a punch is disclosed. Since it is configured in this manner, the cap is removed, the operation member such as the injection member is further removed, the cap is inverted, and the bead portion and the engagement portion of the aerosol container are fitted to each other, whereby the gas ejection hole is stem. The stem can be maintained in a state where the is pushed down. However, such a cap has a complicated structure and a plurality of constituent members. Therefore, the manufacturing process is complicated, which contributes to an increase in the cost of the aerosol product.

  The present invention can discharge all the remaining contents safely and reliably with a simple discharge operation without using a separate member such as a gas venting tool, and can recognize at a glance that it has been discharged. It is an object of the present invention to provide an injection member with a discharge mechanism for aerosol products in which residual contents are not discharged out of the injection member.

  The injection member of the present invention includes a push button having an injection hole attached to an aerosol valve, and a cover member attached to an aerosol container and having an insertion portion into which the push button is inserted and an injection window. In the normal state where the injection window and the injection hole of the push button are mounted in the same direction, the cover member suppresses the rotation of the push button and allows the push button to move up and down. In the discarding state in which the injection window and the injection hole of the push button are arranged in a different positional relationship from the normal state, the push button is fixed at the open position of the valve. ). Here, the phrase “the cover member restrains the rotation of the push button” means that the push button cannot be rotated even when the push button is pushed in and the valve is opened.

  In such an ejection member, it is preferable that the ejection window of the cover member and the ejection hole of the push button face in different directions in the discarded state (claim 2). In this case, the cover member may be removed from the aerosol container, and the cover member rotated relative to the push button to be reattached (Claim 3), the push button is removed from the aerosol valve, and the push button is It is good also as a discarding state by rotating with respect to a cover member and mounting | wearing again (Claim 4). When the push button is removed to be disposed of, it is preferable that a pull-out portion is provided on the upper surface of the push button.

  Further, the push button and the cover member may be removed, and the push button and the cover member may be disposed in a different positional relationship from the normal state and engaged, and then reattached to form a discarded state. 6).

  A second aspect of the injection member of the present invention includes a push button attached to the aerosol valve, a first attachment portion attached to the aerosol container, and a cover member having an insertion portion into which the push button is inserted in the center. The cover member is provided with a second mounting portion to be attached to the aerosol container, the cover member is removed from the aerosol container, the cover member is inverted and attached to the aerosol container at the second mounting portion, The push button is maintained at the open position of the valve (claim 7).

  According to a third aspect of the injection member of the present invention, there is provided a push button having a stem mounting portion mounted on the stem of the aerosol valve, and a cover member having an insertion portion mounted on the aerosol container and having the push button inserted in the center. The push button includes an engaging portion that engages with the cover member, and the push button is removed from the aerosol valve, and the push button is reversed to engage the engaging portion with the cover member. The push button is maintained in the open position of the valve (claim 8). In such an injection member, it is preferable that the push button is engaged with the cover member at the engaging portion while the push button is guided by the cover member (Claim 9), and the push button is preferably provided with a pull-out portion. (Claim 10).

  In the injection member of the present invention, when the aerosol product is not required, the valve is opened by a simple method of removing the cover member and / or the push button, changing the positional relationship between the cover member and the push button, and reattaching the cover member. The push button can be fixed at the position, and the entire contents remaining in the aerosol container can be discharged. Also, depending on whether or not the spray window of the cover member and the spray hole of the push button are oriented in the same direction, that is, by the mutual arrangement of the push button and the cover member, the aerosol product to which this spray member is attached is usually It can be checked whether it is in a state or a discarding state. Therefore, it is easy for the user to recognize whether the contents are discarded, and it is also safe for the disposal company handling the waste aerosol product.

  Further, in the normal state, the cover member only allows the vertical movement of the push button and suppresses the rotation of the push button. It is necessary to change the positional relationship between the cover member and the push button and remount. In other words, since the user's intention is necessary to set the disposal state, the contents are not continuously discharged by the carelessness of the user. Furthermore, since the injection member of the present invention is composed of a push button and a cover member, no separate member such as a gas venting tool is required for discharging the residual contents, so that the manufacture is easy and the cost can be reduced.

  A second aspect of the injection member of the present invention is a cover member having a push button attached to an aerosol valve, a first attachment portion attached to an aerosol container, and an insertion portion into which the push button is inserted in the center. The cover member is provided with a second mounting portion to be mounted on the aerosol container, the cover member is removed from the aerosol container, the cover member is inverted and mounted on the aerosol container at the second mounting portion. Therefore, since the valve can be maintained in the open state, the intention of the user is required to set the valve in the discarded state. Further, since the operation is easy, the remaining content can be easily discharged.

  Furthermore, the third aspect of the injection member of the present invention includes a push button having a stem mounting portion that is mounted on the stem of the aerosol valve, and an insertion portion that is mounted on the aerosol container and into which the push button is inserted. The push button includes an engaging portion that engages with the cover member. The push button is detached from the aerosol valve, and the push button is inverted to engage the engaging portion with the cover member. Thus, the valve can be maintained in an open state, and the same effect as in the second aspect can be obtained.

FIG. 8a shows an inner peripheral wall of still another embodiment of the injection member of the present invention. FIG. 8B is a perspective view showing a state in which the inner peripheral wall and the push button are engaged and integrated, FIG. 9 is a perspective view showing still another embodiment of the injection member of the present invention, and FIG. FIG. 10B is a top cross-sectional view of FIG. 10A, and FIG. 10C is a top cross-sectional view when the injection member of 10a is in a discarded state.

  An injection member 10 shown in FIG. 1a includes a substantially elliptical columnar push button 11, a substantially elliptical insertion portion 12 (see FIG. 1c) into which the push button is inserted, and an injection window 13 formed in the front. And a cylindrical cover member 14. Then, the cover member 14 is removed from the aerosol container, rotated 90 degrees with respect to the push button, and remounted, thereby maintaining the valve in an open state.

  The push button 11 communicates with the stem mounting part (not shown) formed at the lower end, the injection hole 16 provided at the front upper part, and from the upper end of the left and right side surfaces toward the middle part of the side surface. And a straight groove 18 (see FIG. 1b).

  The cover member 14 is comprised from the outer peripheral wall 19 which has a mounting part for mounting | wearing an aerosol container, and the inner peripheral wall 20 which covers the outer periphery of a push button (refer FIG. 1c). An injection window 13 is formed in front of the outer peripheral wall 19, and the inner peripheral wall 20 constitutes the insertion portion 12. A protrusion 21 protruding inward is formed on the upper side surface of the inner peripheral wall 20, and a first notch 22 extending upward from the lower end of the side surface of the inner peripheral wall 20 is formed. The magnitude | size of this 1st notch part 22 is demonstrated in description of the effect | action mentioned later. Further, a second notch 25 extending upward from the lower end is formed on the front surface of the inner peripheral wall 20. The second notch 25 is connected to the ejection window 13 of the cover member. In this embodiment, a third cutout portion 26 similar to the second cutout portion 25 is also formed on the rear surface, thereby reducing the material and reducing the weight of the cover member. However, the third cutout 26 may not be provided. In addition, the mounting portion of the outer peripheral wall may be provided with a notch in part or a thin wall portion so as to be easily removed from the aerosol container.

Since it is configured in this manner, in a normal state in which an aerosol product is normally used, the push button 11 is formed along the shape of the insertion portion 12 (inner peripheral wall 20) of the cover member as shown in FIG. 1a or 2a. The injection hole 16 and the 2nd notch part 25 (injection window 13) have faced the same direction. The projection 21 of the cover member is disposed so as to be movable up and down within the groove 18 of the push button.
Then, when the user presses the upper surface 24 of the push button with a finger or the like, the contents are ejected from the ejection hole 16 to the outside through the ejection window 13. In this normal state, the push button 11 is prevented from rotating by the cover member insertion portion 12. Further, even if the push button 11 is to be removed upward, the protrusion 21 of the cover member and the bottom 23 of the groove 18 of the push button cannot be engaged and removed. In addition, you may provide a protrusion in a push button, and a groove | channel in the insertion part of a cover member.

  Next, the disposal state of this injection member will be described. The disposal state is obtained by removing the cover member 14 of the injection member in the normal state from the aerosol container as shown in FIG. 2b, and rotating the cover member 90 degrees with respect to the push button and remounting. Thus, by rotating the cover member 90 degrees and remounting, the upper end of the first notch 22 of the cover member and the upper surface 24 of the push button 11 are engaged, and the push button is pushed down. That is, the push button is pushed down in a state of being fitted in the first cutout portion 22. Here, the first cutout portion 22 also supports the left and right side surfaces of the push button 11 to suppress the rotation of the push button 11. As a result, the push button can be maintained with the valve opened, and the entire remaining amount can be discharged.

Since the injection member 10 acts in this way, the width of the first cutout portion 22 of the cover member can be fitted into at least the push button, or the upper end of the first cutout portion can suppress both side ends of the push button. It must be as large as possible. Moreover, the length needs to be a length which can push down a push button to the state which opens a valve | bulb, when the cover member 14 is mounted | worn again to an aerosol container.
In this discarded state, since the injection hole 16 of the push button is oriented at a right angle (different direction) to the arrow direction which is the direction of the injection window 13 of the cover member, the discharged content is not injected outside, It is discharged into the cover member 14.

  As described above, the aerosol product provided with the injection member of the present invention can recognize whether the aerosol product is in a normal state or in a disposal state simply by looking at the injection member. It is safe for waste disposal companies who handle aerosol products that are no longer needed and are disposed of as garbage. In addition, since the user's intention is necessary to set the disposal state, the contents are not continuously discharged by the carelessness of the user. Moreover, even if it is in a discarded state, the residual contents are not jetted to the outside, which is safe. Furthermore, since the injection member of the present invention is composed of a push button and a cover member and does not require a separate member such as a gas venting tool, it is easy to manufacture and the cost can be reduced.

  The injection member 30 shown in FIG. 3a has a cylindrical shape including a cylindrical push button 31 having an injection hole, a circular insertion portion 32 into which the push button is inserted, and an injection window 33 formed in the front. The cover member 34 is configured. Similarly to the injection member 10 in FIG. 1, the injection member 30 also removes the cover member from the aerosol container, rotates it, and remounts it to keep the valve open. However, in this embodiment, the cover member can be disposed of by rotating it to an arbitrary angle other than the normal state and remounting it.

  The push button 31 includes an injection hole 35 formed in an upper front portion, and an engagement protrusion 36 formed in a lower portion on both side surfaces of 90 degrees with respect to the injection hole (FIG. 4a, FIG. 4b, see FIG. 4c). The other configuration is substantially the same as the push button 11 of FIG.

  The cover member 34 includes an inner peripheral wall 38 that forms the insertion portion 32, and the inner peripheral wall is formed on both side surfaces at a position of 90 degrees with respect to the injection window 33 and is formed straight upward from the lower end to the middle portion. It has a notch 39, a step 42 formed at the front and rear lower ends of the injection window, and a window 40 formed at the front middle (see FIGS. 3b and 4d). This window 40 forms the ejection window 33 of the cover member. Further, a claw 37b for facilitating removal of the cover member from the aerosol container is formed on the mounting portion 37a at the lower end of the outer peripheral wall 37. Thereby, the aerosol container and the cover member can be clip-fitted at the mounting portion.

3A, in the normal state, the injection hole 35 and the window 40 (injection window 33) face the same direction (arrow direction), and the push button engaging projection 36 is The cover member is movably disposed in the first notch 39 of the cover member. That is, the rotation of the push button is suppressed by the first cutout portion 39 of the cover member, and the engagement protrusion 36 engages with the upper end 41 of the first cutout portion 39 even when the pushbutton is pulled up, The push button cannot be easily removed. However, it may be a groove 39a connected from the upper end to the lower end of the inner peripheral wall as shown in FIG. 4e.
Further, as shown in FIG. 3c, in a discarded state where the cover member is detached from the aerosol container and rotated at an angle of 20 to 160 degrees, preferably 30 to 150 degrees with respect to the push button, the push button is engaged. The protrusion 36 engages with the step portion 42 of the inner peripheral wall 38 of the cover member, and the push button 31 is pushed down. In this case as well, in the discarded state, the injection hole of the push button causes the residual content to be injected onto the inner peripheral wall 38 of the cover member.

  The push button 50 shown in FIG. 5b is used for the injection member of the present invention, and has a rectangular planar shape. The inner peripheral wall 53 of the cover member shown in FIG. 5a can be used for the cover member 14 of FIG. 1, and the insertion portion 51 formed by the inner peripheral wall 53 is formed in a rectangular shape like the planar shape of the push button. ing. In addition, protrusions 52 are formed at the lower portions of both side surfaces of the push button 50. A first cutout portion 54 extending from the lower end to the upper portion is formed on the side surface of the inner peripheral wall 53 of the cover member, and a second cutout portion 55 communicating with the injection window extending from the lower end to the upper portion is formed on the front surface of the inner peripheral wall 53. Is formed. Other configurations are substantially the same as those of the injection member 10 of FIG.

Thus, in the normal state, the injection hole 16 of the push button and the second notch 55 (injection window of the cover member) of the inner peripheral wall face the same direction (arrow direction), and the push button The protrusion 52 is located in the first notch 54 of the cover member. Therefore, even if the push button is pulled upward, the protrusion 52 engages with the upper end 56 of the notch 54 and cannot be easily removed. Further, the rotation of the push button 50 is suppressed by the inner peripheral wall 53.
The ejecting member having the push button 50 also constitutes a disposal state by removing the cover member, rotating the cover member 90 degrees with respect to the push button, and remounting. As a result, similarly to the injection member 10 described above, the upper end 56 of the first notch suppresses the upper surface 57 of the push button and lowers the push button to a position where the valve opens. Then, the entire amount of the remaining content can be injected in the same manner as the injection member 10.

  The push button 60 shown in FIG. 5d has a square shape in plan view, and includes an injection nozzle 61 formed so as to protrude forward in the upper part of the front surface. The inner peripheral wall 63 of the cover member shown in FIG. 5c can be used for the injection member of FIG. 1 similarly to FIG. 5a, and the insertion portion 62 forming the inner peripheral wall 63 is square. However, the width and length are not particularly limited as long as the rectangle is larger than one side of the push button. A first notch 64 extending from the lower end to the middle is formed on the side surface of the inner peripheral wall 63 of the cover member, and a second notch 65 communicating with the injection window from the lower end to the upper is formed on the front surface of the inner peripheral wall 63. Is formed. In the inner peripheral wall 63, the first cutout portion 64 is lower than the height of the second cutout portion 65. The other structure is substantially the same as the cover member of FIG. 5a.

In the normal state, the injection nozzle 61 of the push button and the second cutout portion 65 communicating with the injection window are directed in the same direction (arrow direction). And unlike the push button 50 of FIG. 5b, even if the cover member is removed and the cover member (inner peripheral wall) is rotated 90 degrees with respect to the push button and reattached, the push button is inserted into the insertion portion 62 of the cover member. Is done. However, the injection nozzle 61 protruding from the front surface of the push button is engaged with the upper end 66 of the first notch 64, and the push button 60 is pushed down by the inner peripheral wall 63 of the cover member. By providing the jet nozzle 61 protruding in this manner, the push button 60a having the same shape can be obtained even if the outer shape is circular (see FIG. 5f), or rotated to 90 degrees or an arbitrary angle. Can do.
In addition, a protrusion 67 may be provided at the same height as the injection nozzle 61 at the rear of the push button. Accordingly, the push button can be pushed down before and after the cover member is rotated 90 degrees to be disposed of, and the push button can be pushed down stably.

  Further, the push button 68 of FIG. 5e may be used instead of the push button 60 of FIG. 5d. The push button 68 does not have an injection nozzle, and is provided with a protrusion 69 at the lower part of both side surfaces of the push button. Since it is configured in this manner, in a normal state, the push button protrusion 69 is located in the first cutout portion 64 of the inner peripheral wall 63 to suppress the push button rotation and allow the push button to move up and down. In the discarded state, the protrusion 69 of the push button is suppressed by the lower end of the rear surface 69a of the inner peripheral wall 63, and the push button is pushed down. Further, when such a push button 68 is used, it is preferable that the second notch 65 is closed at the lower end of the front surface of the inner peripheral wall as shown by an imaginary line in FIG. 5c. Accordingly, the protrusion 69 of the push button can be suppressed on the front surface and the rear surface of the inner peripheral wall, and the push button can be lowered stably.

  The injection member 70 shown in FIG. 6a is shown in FIG. 6b by removing the push button 71 of the aerosol product in the normal state from the stem of the aerosol container, rotating the push button 71 90 degrees with respect to the cover member, and then reattaching it. It is to be disposed of.

  The injection member 70 includes a columnar push button 71 and a cylindrical cover member 73 including a circular insertion portion 72 into which the push button is inserted. Further, on the upper surface of the push button 71, a pulling plate 76 made of a rotating plate 75 connected by a thin hinge, a rotating shaft 74 or the like is provided (see FIGS. 6e and 6f) and before and after the lower end of the inner peripheral wall 38. Includes a claw 77 that elastically deforms outward (see FIGS. 6c and 6d). Other configurations are substantially the same as those of the injection member 30 of FIG. 3, and the same reference numerals are used.

  Because of this configuration, in the normal state, the push button engagement protrusion 36 is positioned at the first notch 39 of the cover member in the same manner as the injection member 30 in FIG. The injection hole and the injection window are oriented in the same direction. Furthermore, since the outer peripheral surface of the push button is covered with the cover member and only the upper surface is exposed, the push button cannot be removed even if it is grasped with a finger. However, by pulling the push button using the pull-out portion 76, the engagement between the push button engaging projection 36 and the upper surface of the notch 39 of the cover member can be released.

  In other words, the push button of the injection member in the normal state is removed using the pull-out portion 76, rotated 90 degrees, and reattached to be disposed of. This remounting is performed by pushing down the upper surface of the push button with a finger or the like until the push button engaging projection 36 is clipped with the claw 77 of the cover member. As a result, the cover member maintains the push button in a state where the push button is depressed even when the finger is released, that is, in a state where the valve is opened. A mark such as an arrow indicating the injection direction on the top surface of the push button or a mark such as an arrow indicating the direction in which the push button is to be mounted at the time of disposal is provided on the top surface of the cover member to guide the operation to the disposal state. preferable.

For example, as shown in FIG. 7 a, an arrow 78 a indicating the injection direction is provided on the upper surface of the push button 71, and an arrow 78 b facing 90 degrees with respect to the injection direction is provided on the upper surface of the cover member 73. By providing the arrows 78a and 78b in this way, the disposal operation is facilitated because the disposal state is achieved by aligning 78a and 78b in the same direction.
That is, in the normal state, the arrow of the cover member has an angle of 90 degrees with respect to the arrow of the push button (see FIG. 7a). Then, the pulling plate of the push button 71 of the injection member is erected, and the push button is removed by pulling the pulling plate (see FIG. 7b). Finally, the push button is rotated 90 degrees with respect to the cover member, and is reattached so that the arrow 78b of the cover member and the arrow 78a of the push button are aligned (see FIG. 7c). In this way, by guiding the operation to the disposal state, the burden on the user is reduced, and the user voluntarily discharges the residual contents.

Next, what will be described is to remove both the push button and the cover member from the normal state to the discarded state. In the embodiment introduced so far, by removing both the push button and the cover member and remounting them, the same effect as removing one of them and remounting can be obtained.
However, in the following, both are removed in the normal state, the push button and the cover member are fixed so as to be in a discarded state, and both are remounted. FIG. 8a shows the inner peripheral wall 80 of the cover member, which is substantially the same as the inner peripheral wall of FIG. 1c except that it includes an engaging portion 81 that protrudes inside the first notch 22 of the inner peripheral wall. is there.
Since the cover member and the push button are once removed and the push button 11 is inserted into the first cutout portion 22 of the cover member as shown in FIG. The push button and the cover member are integrated with each other. By reattaching the aerosol container in this state, the push button can be easily fixed with the valve opened.

The ejecting member shown in FIG. 9 is a discarded state by removing the cover member in the normal state from the aerosol container, turning it upside down, and then remounting it. The injection member 90 is provided with a second mounting portion 92 at the upper end of the cover member 14. The other structure is substantially the same as the injection member 10 of FIG.
That is, in the normal state, the push button 11 is inserted along the shape of the insertion portion 12 (inner peripheral wall 20) of the cover member 14, and the injection hole 16 and the injection window 13 face the same direction. The projection 21 of the cover member is disposed so as to be movable up and down within the groove 18 of the push button.

The cover member 14 is removed from the normal state, reversed, and the cover member 14 is attached to the aerosol container by the second attachment portion 92.
