JP5530224B2 - Cap for aerosol container - Google Patents

Description

  The present invention relates to an aerosol container cap attached to, for example, an aerosol container that ejects a medicine or the like, and particularly belongs to the technical field of a structure that ejects gas when it is left.

  In general, an aerosol container includes, for example, a container body in which a medicine and a compressed gas for ejecting the medicine are accommodated, and an injection pipe that is provided in the container body and forms a valve. By pushing the injection tube inward of the container body, the medicine is ejected from the injection tube by the pressure of the gas.

  For example, as disclosed in Patent Documents 1 to 5, a button for operating the ejection pipe is attached to the aerosol container. Moreover, in the aerosol container, after exhausting the medicine, the surplus gas must be ejected and discarded. Each patent document discloses various structures for ejecting excess gas.

  In Patent Document 1, a button for operating the ejection pipe is attached to the aerosol container, and a separate cap that covers this button is detachably attached to the aerosol container. When using, remove the cap and operate the button. The cap is provided with a protrusion that contacts the button, and this protrusion can be switched between a position that contacts the button and a position that is away from the button. Then, during normal storage when the medicine is not used up, the cap is mounted on the aerosol container after the protruding portion of the cap is placed in a position where it does not contact the button. On the other hand, when the surplus gas is ejected after the medicine has been used up, the cap is mounted on the aerosol container after the projection of the cap is switched to a position where it abuts the button. Thereby, the state in which the button was pushed is maintained, and substantially all the gas in the container body is ejected.

  In Patent Document 2, a button is attached to an aerosol container as in Patent Document 1, and a separate cap is detachably attached to the aerosol container. The top plate portion of the cap is formed so as to be deformed downward and engage with the button. When the remaining gas is ejected after the medicine has been used up, the top plate of the cap is deformed downward to engage the button, and the button is kept pressed so that almost all the gas is Erupts.

  In Patent Document 3, a button is swingably provided on a cap formed to cover the spray tube of the aerosol container so that the spray tube is pushed by swinging the button downward. It has become. A through hole is formed in the cap, and a bar for maintaining the state where the button is swung downward is inserted into the through hole. By inserting the bar into the through hole, the button is pushed and almost all gas is ejected.

  In patent document 4, the button is provided in the cap formed so that the ejection pipe | tube of an aerosol container may be covered. A hooking portion that is elastically deformed toward the inside of the cap is formed on the peripheral wall portion of the cap. When the user exhausts the surplus gas after the medicine is used up, the user pushes the latching portion inward with the button depressed, and elastically deforms the latching portion to engage the button. As a result, the state where the button is pressed is maintained, and substantially all gas is ejected.

  In Patent Document 5, as in Patent Document 4, a button is provided on the cap. Left and right elastically deforming portions that are elastically deformed toward the inside of the cap are formed on the left and right side wall portions of the cap. When ejecting the surplus gas after using up the medicine, the user pushes the left and right elastic deformation portions inward of the cap while pressing the button down, and elastically deforms it to engage the button. As a result, the state where the button is pressed is maintained, and substantially all gas is ejected.

  However, in Patent Documents 1 and 2, a structure for ejecting surplus gas is provided in a removable cap that is removed during use, so if the user accidentally loses the cap, When the excess gas is ejected, the user has to keep pressing the button, which is cumbersome.

  Moreover, in patent document 3, when ejecting surplus gas, you have to prepare a bar. Moreover, the bar needs to be thick enough to be inserted into the through-hole of the cap, and to have a hardness and length enough to push the button. It is troublesome to prepare such a suitable bar.

  Therefore, as in Patent Documents 4 and 5, a button is provided on the cap that covers the spray tube of the aerosol container, so that the cap is not removed from the container during use, and the button is kept pressed against the cap. It is conceivable to provide an elastically deforming part for this purpose. This eliminates the possibility of losing the cap and eliminates the need for preparing a separate member as in Patent Document 3.

  However, in Patent Document 4, the elastic deformation portion of the cap must be continuously pressed until it is caught by a part of the button. At this time, in order to hook the elastic deformation portion onto the button well, it is necessary to correspond the degree of pressing of the button and the deformation amount of the elastic deformation portion, and the operability is poor. Also in Patent Document 5, the degree of pressing of the button and the amount of deformation of the elastic deformation portion must be made to correspond, and the two elastic deformation portions on the left and right sides of the cap are pushed until they are caught by a part of the button. It must be continued, requires a lot of power, and the operability is poor.

  The present invention has been made in view of such a point, and the object of the present invention is to operate an ejection pipe of an aerosol container when ejecting surplus gas after the medicine in the aerosol container is used up. An object of the present invention is to improve the workability of ejecting gas by preparing a member separate from the button and maintaining the button in a state where the button is pressed with a simple and small force.

  In order to achieve the above object, in the present invention, a button is provided on a cap body fixed to an aerosol container, and a stopper for a button in a pressed state is provided on the cap body. It is possible to switch to a state where the button is in contact with the button, and the contact state is maintained even when the operating force is removed.

1st invention is the state which was provided in the container main body in which the ejection gas and the compressed gas for ejecting this ejection material were accommodated, and was able to be pushed inward with respect to this container main body, and was pushed inward In the aerosol container cap attached to the aerosol container having the ejection pipe for ejecting the ejected matter by the gas pressure, the cap body fixed to the aerosol container is displaced in the pushing direction of the ejection pipe. A button and a stopper that abuts the button in the pushed state in which the ejection pipe is pushed and prevents the button from returning to the original state. The stopper abuts the button in the pushed state. A switching mechanism that switches between a contact state that prevents the button from returning to a normal state and a non-contact state that leaves the button in a pressed state; Toggle the stopper abutment by the action of a predetermined operating force to Rutoki, is configured to maintain the contact state in a state where the operation force is removed, the above-mentioned button, abuts on the stopper abutting The cap body has a first side wall and a second side wall made of resin disposed so as to sandwich the contact portion, and the stopper is a contact portion of the first side wall portion. A first movable part connected to the side through a thin hinge, and a second movable part connected to the contact part side of the second side wall part through a thin hinge, the first movable part, The second movable part is connected through a thin hinge .

  According to this structure, since the button and the stopper of the button are provided on the cap body fixed to the aerosol container, when the surplus gas is ejected, a removable cap or stick as in the conventional example is used. It is possible to keep the button pressed by simply switching the stopper to the abutting state without preparing a separate member such as a material, and the excess gas in the aerosol container can be ejected from the ejection pipe become.

  When the stopper in the non-contact state is switched to the contact state, only a predetermined operation force is applied, and then the stopper maintains the contact state even if the user removes the operation force. Since the pressed button is prevented from coming into contact with the stopper in the abutting state and returning to the original state, until it is caught by a part of the button as in the case of providing an elastic deformation portion of the cap of the conventional example The operation of pressing and holding the button becomes unnecessary, and it is sufficient to apply a small force for a short time, thereby simplifying the operation.

Further, the stopper can be easily switched to the contact state by rotating the first movable portion and the second movable portion of the stopper around the thin hinge. At this time, the first movable part is integrally formed on the first side wall with a thin hinge, and the second movable part is integrally formed on the second side wall with a thin hinge, thereby suppressing an increase in the number of parts.

  According to a second invention, in the first invention, the button has a pressing portion for placing a user's finger to apply a pressing force, and the pressing portion and the stopper are the diameter of the ejection tube of the aerosol container. It is characterized by being arranged apart in the direction.

  According to this configuration, the pressing portion on which the user places his / her finger and the stopper operated by the user are located away from each other in the radial direction of the ejection pipe. Therefore, when pressing the pressing part with the finger of one hand to push the button and operating the stopper with the finger of the other hand to switch to the contact state, the pressing part and the stopper are By being separated, one operation is unlikely to interfere with the other operation.

  A third invention is characterized in that, in the first or second invention, the stopper is arranged at an end of the cap body opposite to the side fixed to the aerosol container.

According to this configuration, since the stopper is separated from the aerosol container, the shape and size of the aerosol container are hardly affected when the stopper is operated .

  According to the first invention, since the button and the stopper are provided on the cap body fixed to the aerosol container, when the surplus gas is ejected, the stopper is brought into contact with the button without preparing a separate member. Just switch to the contact state. Furthermore, since the stopper switching mechanism switches to the contact state by the action of a predetermined operation force and maintains the contact state even if the operation force is removed, the button can be pressed easily and with a small force. It can be held, and the workability for ejecting gas can be improved.

The cap body is provided with a first side wall and a second side wall made of resin so as to sandwich the contact part of the button, and the stopper is connected to the first side wall through a thin hinge. And a second movable part connected to the second side wall part via a thin-walled hinge, and these movable parts are connected via a thin-walled hinge, so that the stopper abuts while suppressing an increase in the number of parts. The operability when switching to the state can be improved.

  According to the second invention, the pressing portion of the button and the stopper can be arranged apart from each other, which can be easily performed when the pressing portion and the stopper are operated with fingers of different hands.

According to the third invention, since the stopper is disposed at the end of the cap body opposite to the side fixed to the aerosol container, the shape and size of the aerosol container are less likely to affect the operation of the stopper. The operability can be further improved .

  The first left thin-walled hinge 52a is integrally formed with the left wall 13 and the left movable piece 52 so as to connect the stopper forming portion 13a and the right edge of the left movable piece 52. Extending in the direction. Therefore, the left movable piece 52 can be rotated in the vertical direction around the first left thin hinge 52a.

  The second right thin hinge 53a is integrally formed with the right movable piece 51 and the central movable piece 53 so as to connect the left edge portion of the right movable piece 51 and the right edge portion of the central movable piece 53, and its rotation axis Extends in the front-rear direction. Accordingly, the central movable piece 53 can be rotated around the second right thin hinge 53a.

  The second left thin hinge 53b is integrally formed with the left movable piece 52 and the central movable piece 53 so as to connect the right edge portion of the left movable piece 52 and the left edge portion of the central movable piece 53, and its rotation axis Extends in the front-rear direction. Accordingly, the central movable piece 53 can also be rotated around the second left thin hinge 53b. The right movable piece 51 and the left movable piece 52 are connected via thin-walled hinges 51a, 52a, 53a, 53b. The thin-walled hinges 51a, 52a, 53a, and 53b constitute the switching mechanism of the present invention.

  As shown in FIG. 4, when the width W1 of the right movable piece 51, the width W2 of the left movable piece 52, and the width W3 of the central movable piece 53 are summed, the stopper forming portion 12a of the right wall portion 12 and the stopper of the left wall portion 13 are obtained. The dimensions W1 to W3 and L of each part are set so as to be longer than the gap dimension L in the left-right direction of the forming part 13a.

  Therefore, in the state where the external force by the user or the like is removed, the right, left, and central movable pieces 51 to 53 are not arranged on a straight line extending in the left and right directions, and the central movable piece 53 as shown in FIGS. Is located above the first right thin hinge 51a and the first left thin hinge 52a, and as shown in FIGS. 6 to 8, the central movable piece 53 is provided with the first right thin hinge 51a and the first left thin hinge 52a. It becomes one of the states located below.

  The state shown in FIGS. 1 to 5 of the stopper 50 is a non-contact state in which the stopper 50 does not contact the contact plate 35. When the stopper 50 is in a non-contact state, the button 30 is in a pressed state (a state in which an insecticide is ejected from the nozzle 32 as shown in FIG. 5), and when the button 30 is not pressed ( As shown in FIG. 2, the abutting plate 35 is separated both when the pesticide is not ejected from the nozzle 32. At this time, the central movable piece 53 is located above the upper edge of the contact plate 35 and above the right movable piece 51 and the left movable piece 52. The right movable piece 51 is inclined so that its left side is located above the right side, and the left movable piece 52 is inclined so that its right side is located above the left side. Therefore, the central movable piece 53, the right movable piece 51, and the left movable piece 52 form an arch that curves upward.

  Furthermore, in the non-contact state, the central movable piece 53 that is positioned at the top is positioned slightly below the upper end portions of the right side wall portion 12 and the left side wall portion 13. As a result, the central movable piece 53, the right movable piece 51, and the left movable piece 52 are protected by the right side wall portion 12 and the left side wall portion 13, and the stopper 50 is damaged due to an unexpected contact with an article or the like. Can be avoided, and abrupt switching from the non-contact state to the contact state can also be prevented.

  When the stopper 50 in the non-contact state is pushed downward from above, it switches to the contact state. That is, when the central movable piece 53, the right movable piece 51, and the left movable piece 52 are pushed from above, the movable pieces 51 to 53 are elastically deformed, and the right side wall portion 12 and the left side wall portion 13 are spaced from each other. Elastically deforms so that it spreads from side to side As a result, as shown in FIG. 8, the right movable piece 51 rotates downward around the first right thin hinge 51a, and the left movable piece 52 rotates downward around the first left thin hinge 52a. The central movable piece 53 rotates around the second right thin hinge 53a and the second left thin hinge 53b. The right movable piece 51 is inclined so that the left side is located below the right side, and the left movable piece 52 is inclined so that the right side is located below the left side. At this time, as shown in FIG. 7, if the button 30 is in the pushed state, the rear end portion of the central movable piece 53 of the stopper 50 and the front edge portion of the contact plate 35 of the button 30 come into contact with each other. Thus, even if the pressing force to the button 30 is removed, the contact plate 35 is prevented from coming into contact with the central movable piece 53 and the button 30 is prevented from returning from the pressed state to the original state.

  Specifically, after the button 30 is pushed all the way to the stroke end with the finger of one hand and the stopper 50 is switched to the contact state with the finger of the other hand, the finger of the one hand is released from the button 30. By removing the button 30, the button 30 returns to the original state to some extent, but does not completely return to the original state due to contact with the stopper 50, and maintains a sufficient amount of gas ejection from the nozzle 32.

  Next, the case where the aerosol container cap 1 configured as described above is used by being attached to the aerosol container 100 will be described. The stopper 50 is kept in a non-contact state.

  When the aerosol container cap 1 is attached to the aerosol container 100, the aerosol container cap 1 is pressed against the container body 101 from above. Then, the right and left fitting portions 16 of the aerosol container cap 1 are elastically deformed so that the claw portions 16a are fitted into and engaged with the concave portions 101a of the container body 100. Thereby, the cap 1 for aerosol containers is attached to the aerosol container 100, and the upper end part of the ejection pipe 102 is inserted and connected to the inner side of the lower end part of the discharge pipe 31 of the cap 1 for aerosol containers.

  When spraying an insecticide, as shown in FIG. 5, the user places a finger (indicated by a virtual line) on the finger placement portion 37 of the aerosol container cap 1. When the finger placement portion 37 is pressed, the spring portion 14 is elastically deformed in the vicinity of the front end portion, and the discharge pipe 31, the nozzle 32, and the contact plate 35 are displaced downward. The ejection pipe 103 is pushed inward of the container body 101 by the downward displacement of the discharge pipe 31. When the ejection pipe 103 is pushed, the insecticide in the container main body 101 is ejected from the ejection pipe 102 by the pressure of the gas, and is discharged from the front end of the nozzle 32 through the discharge pipe 31.

  Next, the case where gas remains after using the insecticide will be described. First, a user's finger is placed on the finger placement portion 37 of the aerosol container cap 1 and pushed as shown in FIG. 5 to push the ejection tube 103. As a result, gas is released from the nozzle 32.

  Thereafter, the stopper 50 is pushed downward with the finger of the other hand to switch from the non-contact state to the contact state shown in FIG. At this time, as described above, the operating force applied to the stopper 50 is merely to rotate the movable pieces 51 to 53 around the thin hinges 51a, 52a, 53a, 53b, so that only a small force is required, and the non-contact state. After switching, the state is maintained even if the operating force is removed, so there is no need to keep pressing until it is caught by a part of the button 30 as in the case of providing the elastic deformation part of the conventional example, It is only necessary to apply a small force for a short time, and the operation becomes simple.

  Further, since the finger placement portion 37 and the stopper 50 are located on the opposite side in the radial direction (the front-rear direction of the cap 1) with respect to the ejection tube 102, they are separated from each other, so that the button with the finger of one hand The operation of 30 and the operation of the stopper 50 by the finger of the other hand do not interfere with each other, and the operability of the stopper 50 is good.

  In addition, since the stopper 50 is disposed at the upper end of the cap body 10 opposite to the side (lower side) fixed to the aerosol container 100, the shape and size of the aerosol container 100 is the operation of the stopper 50. It becomes difficult to affect.

  When the finger is released from the finger placement portion 37 after the stopper 50 is switched to the contact state, the rear end portion of the central movable piece 53 of the stopper 50 is in the pressed state as shown in FIG. It contacts the front edge of the contact plate 35. As a result, even if the user removes his / her finger from both the finger placement portion 37 and the stopper 50, the button 30 is prevented from returning to its original state, and the gas remains ejected. If it is desired to stop the gas ejection halfway, the button 30 can be returned to its original state by bringing the stopper 50 into a non-contact state, which can be done with a simple operation.

  As described above, according to the aerosol container cap 1 according to this embodiment, since the button 30 and the stopper 50 are provided on the cap body 10, when the surplus gas is ejected, the conventional example is used. It is possible to keep the button 30 pressed by simply switching the stopper 50 to the contact state without preparing another member such as a detachable cap or bar, and the remainder in the aerosol container 100. Gas can be ejected.

  When the stopper 50 in the non-contact state is switched to the contact state, it is not necessary to keep pressing as in the conventional example, and a small force may be applied for a short time. The button 30 can be held while being pressed with force, and the workability of ejecting gas can be improved.

  In addition, since the finger placement portion 37 and the stopper 50 of the button 30 are separated from each other, the operation can be easily performed when the finger placement portion 37 and the stopper 50 are operated with fingers of different hands.

  In addition, since the stopper 50 is disposed at the upper end of the cap body 10 opposite to the side fixed to the aerosol container 100, the shape and size of the aerosol container 100 are less likely to affect the operation of the stopper 50. The operability can be further improved.

  The cap body 10 is provided with a right side wall portion 12 and a left side wall portion 13 made of resin so as to sandwich the contact plate 35 of the button 30. The stopper 50 includes a right movable piece 51 connected to the right wall portion 12 via a first right thin hinge 51a, and a left movable piece 52 connected to the left wall portion 13 via a first left thin hinge 52a. Therefore, the operability when the stopper 50 is switched to the contact state can be improved while suppressing an increase in the number of parts.

  In the above embodiment, the stopper 50 is brought into contact with the contact plate 35 of the button 30. However, the present invention is not limited to this, and the stopper 50 is brought into contact with the discharge pipe 31, the nozzle 32, the finger placement portion 37, and the like. You may make it contact. When contacting the discharge pipe 31, the nozzle 32, and the finger placement portion 37, the position where the stopper 50 is provided may be changed to a corresponding portion.

  Further, the structure of the stopper 50 is not limited to the above. For example, the central movable piece 53 may be omitted, and the right movable piece 51 and the left movable piece 52 may be connected by a thin hinge.

  As described above, the aerosol container cap according to the present invention is suitable for use by being attached to an aerosol container containing an insecticide or the like, for example.
