Description

  The present invention relates to an aerosol cap having a residual gas discharge mechanism and an aerosol device including the aerosol cap.

  There is known an aerosol product in which liquid or powdery contents and a liquefied gas are filled in a container, and contents such as an insect repellent and a disinfectant are sprayed in a mist state by the pressure of the liquefied gas. In general, a user who uses an aerosol product often determines that the contents have been used up when the contents are not ejected and there is no sound emitted from the ejection port, and is treated as garbage as it is.

  However, even if it is determined that the user has used up the aerosol product, the liquefied gas for releasing the contents may actually remain in the aerosol container, and if this liquefied gas is left as a garbage, When compressed during the collection process, the aerosol container may rupture, igniting fires, etc., leading to a fire.

  In order to avoid such a situation, in recent years, an aerosol product having a residual gas discharge mechanism has been proposed so that the user can completely discharge the residual gas from the aerosol container and then discard it. Various types of residual gas discharge mechanisms are provided.

  For example, in Patent Document 1, a cover cap body mounted on an aerosol container is provided with a pair of open plates and vent holes, and once the cover cap is removed from the aerosol container and the open plates are crossed again. A residual gas discharge mechanism is described in which a cover cap main body is attached to an aerosol container to maintain the stem of the aerosol container in an open state and release gas from a gas vent hole.

Further, in Patent Document 2, the operation button mounted on the aerosol container is provided with a gas vent recess mounted in the gas vent state on the top surface opposite to the content discharge recess mounted in the normal use state. When shifting to the degassing state, once remove the contents discharge recess of the operation button from the stem of the aerosol container, turn the operation button upside down, and then attach the operation button degassing recess to the stem again. Thus, a residual gas discharge mechanism is described that is configured to maintain the stem of the aerosol container open.

  However, the degassing cap described in Patent Document 1 has a button for pressing the stem and a cap formed of separate members. Therefore, when discharging the residual gas, the cap body is once removed from the aerosol container, and the open plate After crossing, the operation of attaching to the aerosol container is necessary again, and the operation is complicated. In the case of the operation button for an aerosol container described in Patent Document 2, an operation for removing the button itself from the aerosol container and a work for reattaching the button while aligning with the aerosol container are required. In such an operation, if the aerosol container and the button body cannot be aligned well, it is difficult to attach the aerosol container to the button body, and the installation operation may take time and may be troublesome.

  The present invention has been made in view of the above problems, and provides a cap with a small number of parts, and can easily shift from a normal use state to a residual gas discharge state in an aerosol product, And it aims at providing the cap which can maintain a residual gas discharge | emission state.

A button body and a cap main body portion having an engaging portion that engages with the button portion. The button portion and the cap main body portion are integrally formed via a weak rigid body portion, and the weak rigid body portion is While being deformed, the stem is pressed by a portion different from the stem mounting portion, and the engagement state between the button portion and the engaging portion is maintained by the pressing force for pressing the stem and the repulsive force of the stem, and the pressing state of the stem is It is maintained.

  According to the cap configured as described above, the button portion and the cap main body portion are integrally formed via the weak rigid body portion, so that the user can deform the weak rigid body portion and press the stem, and the engaging portion. The action of maintaining the pressed state can be performed by a series of operations. Moreover, since the button part and the cap main body part are integrated, when manufacturing the aerosol device, it is not necessary to manufacture the button part and the cap main body part separately and attach them separately to the aerosol container. Accordingly, it is possible to reduce the manufacturing cost of the cap itself and the manufacturing cost of the aerosol device. Furthermore, the engagement state between the button portion and the engagement portion is maintained by the pressing force for pressing the stem and the repulsive force of the stem, and the pressing state of the stem is maintained, so that the user continues to press the button portion. Even without this, the residual gas in the aerosol container can be exhausted to the end. Therefore, the user can easily shift to the residual gas discharge state with a small number of steps and a small force, and the contents can be reliably discharged.

  In the cap configured as described above, the weak rigid body portion includes a valley fold portion that is deformed into a valley fold shape and a mountain fold portion that is deformed into a mountain fold shape, and the valley fold portion is deformed into a valley fold shape. Accordingly, a portion different from the stem mounting portion is brought into contact with the stem, and the mountain fold portion is deformed into a mountain fold shape, whereby the stem is pushed down by a portion different from the stem mounting portion.

  According to such a configuration, it is possible to smoothly guide the user's operation by simply deforming the valley fold according to the shape and deforming the mountain fold according to the shape. It is possible to easily make the transition to.

  In the cap configured as described above, the button portion includes an engagement plate that engages with the engagement portion, and the end portion of the engagement plate is formed in a shape corresponding to the end portion while the weak rigid body portion is deformed. A portion different from the stem mounting portion and the stem are aligned when abutted against the end abutting portion.

  According to such a configuration, the user can align the portion different from the stem mounting portion with the stem simply by bringing the engagement plate into contact with the end contact portion. And accurate alignment can be performed. Therefore, it is possible to smoothly shift to the residual gas discharge state.

  Further, in the cap configured as described above, the portion different from the stem mounting portion is formed so as to be attachable to the stem, and the content ejected from the stem when the portion different from the stem mounting portion is mounted on the stem and the stem is pressed down It is characterized by having a discharge hole for discharging the inside of the cap body.

  According to such a configuration, since the contents ejected from the stem collide with a portion different from the stem mounting portion, the ejection direction is changed, and the contents are ejected from the discharge hole into the cap body. After weakening the force, it can be gradually discharged outside the cap body. Therefore, the contents are not accidentally jetted toward the surrounding people in the residual gas discharge state.

  According to the present invention, in an aerosol product, a user can make a transition from a normal use state to a residual gas discharge state with a small number of procedures and a slight force, and can reliably discharge the residual gas.

  As shown in FIG. 3, the front side fingertip guide recess 5a is formed to be slightly wider than the rear side fingertip guide recess 5b. The user can operate the aerosol device 60 by attaching a finger to the button portion 4 from the wide rear fingertip guide recess 5b. Also, as shown in FIG. 3, the engagement plate 17 of the button portion 4 is formed in a curved shape so that the width of the rear side fingertip guide recess 5b is gradually shorter than the width of the front side fingertip guide recess 5a. End portion abutting portions 28 and 28 with which 17 abuts are formed.

  Furthermore, engaging portions 9 and 9 that engage with the button portion 4 are formed in a substantially central portion of the fingertip guiding recess 5. The engaging portions 9 and 9 are arranged so as to face each other through the button portion 4 at a substantially boundary position between the top plate portions 6 and 6 and the hollow portions 7 and 7. Furthermore, the engaging portions 9, 9 have a substantially rectangular shape when viewed from the top, and the longitudinal direction thereof is formed substantially parallel to the injection direction of the contents injected from the injection port 10.

Next, the structure of the button unit 4 will be described.
Since the button part 4 is extended | stretched from the part 3 of the cap main-body part 2, as shown in FIG. As shown in FIG. 5, the button part 4 has a weakness between a thin valley fold part 11 deformed into a valley fold from a part 3 of the cap body 2 and a similarly thin mountain fold part 12 deformed into a mountain fold. It is formed so as to extend from the front side fingertip guide concave portion 5b to the rear side fingertip guide concave portion 5b through the extending plate 13 having a rigid portion.

  An injection port 10 for injecting the contents ejected from the stem 14 is formed in the front part of the button part 4. In a normal use state, the contents ejected from the stem 14 are ejected from the ejection port 10 to the outside via the ejection path 15. As shown in FIG. 3, a concave portion having a circular shape when viewed from above is formed in the rear portion of the button portion 4, and a portion for guiding the user's fingertip attached as the pressing portion 18 of the button portion 4 from the rear side fingertip guide concave portion 5 b It has become.

  Further, as shown in FIG. 2, a notch 21 is formed in the lower part of the pressing part 18 by notching the rear part of the button part 4 in a gently curved shape. By forming the notch portion 21, when the user shifts to the residual gas discharge state, the user can easily align the finger with the notch portion 21 and lift the button portion 4 to be hooked on the distal end portion 22 of the pressing portion 18. It is possible to release the mounting state of the stem 14 and the stem mounting portion 16.

  Further, the button portion 4 has engagement plates 17 and 17 that engage with the engagement portions 9 and 9 of the cap body portion 2, and the end portions 17 a and 17 a of the engagement plates 17 and 17 correspond to the end portions of the cap body portion 2. It is formed in a curved shape corresponding to the contact portions 28, 28. As described above, since the curved shapes corresponding to each other are formed, when the user shifts from the normal use state to the residual gas discharge state, the end portions 17a and 17a of the engagement plates 17 and 17 of the button portion 4 are not connected to the end portions. It is easy to align with the part contact parts 28 and 28.

  Further, the end contact portions 28 and 28 are arranged such that the second stem mounting portion 19 described later is aligned with the stem 14 when the weak rigid body portion is deformed and contacted with the end portions 17a and 17a. Therefore, the user can smoothly shift to the residual gas discharge state without relying on the scale amount or the like for the alignment operation.

  As shown in FIG. 4, a cylindrical stem mounting portion 16 is formed in the approximate center of the back surface side of the button portion 4, and is formed further behind the stem mounting portion 16 so that it can be mounted on the stem 14 in a residual gas discharge state. A substantially cylindrical second stem mounting portion 19 is formed. Discharge holes 20, 20 are formed on the side wall of the second stem mounting portion 19 to discharge the contents ejected from the stem 14 into the cap body 2.

(Action of aerosol cap)
Next, the action of the aerosol cap 1 when shifting from the normal use state to the residual gas discharge state will be described with reference to FIGS. 5 is a cross-sectional view taken along the line AA ′ of FIG. 3 showing the non-injection state in the normal use state, FIG. 6 is a first operation cross-sectional view showing the state of transition from the normal use state to the residual gas discharge state, Is a second operation sectional view, FIG. 8 is a sectional view showing a state after transition from a normal use state to a residual gas discharging state, FIG. 9 is a sectional view showing a discharging state in the residual gas discharging state, and FIG. It is the figure which showed the engagement state of the plywood and the engaging part.

  As shown in FIG. 5, the stem 14 of the aerosol container 50 is attached to the stem attachment portion 16 in the non-injection state in the normal use state. When the user presses the pressing portion 18 from this state, the button portion 4 is pushed downward obliquely downward of the aerosol cap 1, whereby the stem 14 is pressed and the normal injection state in which the contents are injected can be shifted.

  On the other hand, from the non-injection state in the normal use state, it is easy if the user raises the button portion 4 in the direction of the arrow F1 so that the user aligns the finger with the notch portion 21 and hooks the tip portion 22 of the pressing portion 18 as shown in FIG. In addition, the mounting state of the stem 14 and the stem mounting portion 16 can be released. At the same time that the button portion 4 is lifted in the direction of the arrow F1, the valley portion 11 of the weakly rigid body portion is bent in the valley folding direction.

  Next, the user abuts the end portions 17a, 17a with the end contact portions 28, while abutting the engagement plates 17, 17 of the button portion 4 so as to be below the engagement portions 9, 9 of the cap body portion 2. The button part 4 is moved in the direction of arrow F2 until it abuts on the button 28. When moved in the direction of the arrow F2 until it is brought into contact with the end contact portions 28, 28, the second stem mounting portion 19 is aligned with the stem 14 as shown in FIG. At this time, the valley fold part 11 is further bent, and an acute angle part 24 is formed by the stretched plate 13 and a part 3 of the cap body part 2. On the other hand, the mountain folding part 12 is bent in the mountain folding direction.

  As shown in FIG. 8, when the second stem mounting portion 19 is aligned with the stem 14, the user presses the button portion 4 in the direction of the arrow F <b> 3 and causes the stem 14 to mount the second stem mounting portion 19. . The mountain folded portion 12 is further bent, and the bent portion 25 composed of the valley folded portion 11, the mountain folded portion 12, and the stretched plate 13 is deformed into a Z shape in a sectional view.

  Furthermore, as shown in FIG. 9, when the button part 4 is pushed down in the direction F3 and the second stem attachment part 19 and the stem 14 are completely attached, the engagement plates 17 and 17 and the engagement parts 9 and 9 are connected. By being engaged, the pressed state of the stem 14 by the second stem mounting portion 19 different from the stem mounting portion 16 is maintained. When residual gas is ejected from the stem 14, the residual gas is discharged into the cap body 2 from the discharge hole 20 formed in the side wall of the second stem mounting portion 19. The residual gas discharged from the discharge hole 20 gradually spreads inside the cap body 2 as indicated by arrows X and Y, and finally discharged from the discharge port 23 shown in FIG. The

  As described above, according to the aerosol cap 1 according to the present embodiment, the user lifts the button portion 4 to release the mounting state of the stem 14 and the stem mounting portion 16 and makes the valley fold portion 11 into a valley fold shape. The second stem mounting portion 19 is brought into contact with the stem 14 by being deformed, and the stem 14 is pushed down by the second stem mounting portion 19 by deforming the mountain fold portion 12 into a mountain fold shape. Since an object is ejected, the action of pressing the stem 14 and the action of maintaining the pressed state by the engaging portion 9 can be performed by a series of operations.

  In addition, the pressing force for pressing the stem 14 and the repulsive force of the stem 14 maintain the engagement state between the engagement plate 17 and the engagement portion 9 of the button portion 4 and also maintain the pressing state of the stem 14. Even if the user does not keep pressing the pressing portion 18 of the button portion 4, the residual gas in the aerosol container 50 can be exhausted to the end. Therefore, the user can easily shift to the residual gas discharge state with a small number of steps and a small force, and the contents can be reliably discharged.
