Description

The present invention relates to a trigger-type aerosol device, and more particularly to an aerosol cap used for a large-capacity trigger-type aerosol container.

In a conventional trigger type aerosol device, when the aerosol cap is mounted on a relatively small capacity aerosol container, the user only needs to grasp the trigger part of the aerosol cap with one hand, and the weight of the aerosol device is sufficient. It is possible to support. However, when the conventional aerosol cap is mounted on a relatively large-capacity aerosol container and used, the weight of the aerosol device cannot be sufficiently supported only by grasping the trigger part of the aerosol cap with one hand. There is a problem that the operation of the trigger becomes difficult.

In addition, regardless of whether the aerosol body has a relatively small capacity or a relatively large volume, when injecting for a long time, it is necessary to hold the can for a long time in order to operate it with one hand, and the trigger is operated. There is a problem that it becomes difficult.

In addition, for users such as children, women, and the elderly who do not have sufficient grip strength to support the weight of the aerosol device, it is necessary to support the aerosol device with the other hand when using the aerosol container. There was an inconvenience that both hands were blocked.

For example, in the case of the aerosol sprayer described in Patent Document 1, the user needs to hang his index finger on the trigger portion and grasp the cover peripheral wall and the upper part of the aerosol can with other fingers and palms to support the weight of the aerosol device. Is. If the index finger is released when operating the trigger, the burden of supporting the weight of the aerosol device with other fingers or palms increases. Therefore, it becomes difficult to support the weight of the large-capacity aerosol can with only one hand, and it becomes difficult to inject for a long time, and the cap portion of the aerosol-type atomizer described in Patent Document 1 supports the weight of the large-capacity aerosol device. It is not suitable for long-term injection.

A locking surface for locking is provided. However, since the plate-shaped portion is provided only on the rear portion of the mounting cap and the area for locking the upper surface of the hand is small, the weight of the container body is mainly supported by the grip force for gripping the grip portion. That is, the plate-shaped portion can play a role as a non-slip of the hand, but is not suitable for supporting the weight of a large-capacity aerosol device and for performing injection for a long time.

Further, in the trigger type liquid ejector of Patent Document 3, the lower end portion and the rear portion of the main body cover have a protruding shape, but the main body cover is only covered on the upper portion of the ejector main body, and has a large capacity. Not suitable for supporting the weight of aerosol devices. Further, even if the trigger is gripped so that the back of the hand is hooked on the overhanging portion of the main body cover of Patent Document 3, the lower end of the main body cover and the back of the hand are in contact with each other by a line, so that the lower end bites into the back of the hand and a large-capacity aerosol is used. Not suitable for supporting the weight of the container.

1A and 1B are perspective views showing an aerosol cap 1 according to a first embodiment of the present invention. The aerosol cap 1 according to the present invention includes a nozzle 21 having a ejection hole 20 for ejecting a fluid in an aerosol container, a lever 30 integrated with the nozzle 21 or engaging with the nozzle 21, and a cap body covering the nozzle 21 and the lever 30. The cap main body 40 has a blade portion 50 protruding from at least a side surface portion 41 of the cap main body 40. The cap body 40 preferably has a side surface 41 of the cap body 40 and a blade 50 protruding from the rear 42 of the cap body 40, as shown in FIGS. 1A and 1B. However, the blade portion 50 may not protrude from the rear portion 42 of the cap main body 40, but may protrude only from the side surface portion 41 of the cap main body 40.

Further, the cap body 40 is provided with an erroneous injection prevention member 24 for preventing erroneous injection. When the erroneous injection prevention member 24 is removed from the cap body 40, injection becomes possible. The erroneous injection prevention member 24 is connected to the nozzle 21. The erroneous injection prevention member 24 is preferably connected to the nozzle 21 at one location, but the present invention is not limited to this, and the erroneous injection prevention member 24 may be connected at a plurality of locations.

Further, the cap body 40 has a raised portion 70 protruding from the side surface portion 41 of the cap body 40. Unlike the blade portion 50, the raised portion 70 does not protrude from the rear portion 42 of the cap body 40. The raised portion 70 is provided at a position below the blade portion 50. Typically, it is provided at the bottom of the cap body 40, but the present invention is not limited to this, and any position below the blade portion 50 may be provided so as to protrude from an arbitrary position of the side surface portion 41 of the cap body 40. good. The raised portion 70 is provided at a distance from the blade portion 50 so that the user can grasp between the raised portion 70 and the blade portion 50 with a finger. By forming a recess by the blade portion 50 and the raised portion 70 of the cap body 40, it can be expected that the sense of stability and usability when the user grips the cap body 40 is improved.

As shown in the usage example of FIG. 7, the aerosol cap 1 is mounted on the upper part of the aerosol container 2 for storing the fluid drug, and constitutes the aerosol device 10. When the user holds the aerosol cap 1 by hand and holds the lever 30 with the index finger, the drug stored in the aerosol container 2 is ejected from the ejection hole 20 of the nozzle 21.

The lower surface of the blade portion 50 comes into contact with the upper surface side of the index finger and thumb or the back of the hand at the base of the index finger and thumb when the user hangs the index finger on the lever 30 and holds the aerosol cap 1 by hand.

Further, the aerosol cap 1 may further include a plate-shaped member 60 under the ejection hole 20 of the nozzle 21. The plate-shaped member 60 may be provided so as to be parallel to the ejection direction of the drug inside the nozzle 21. The plate-shaped member 60 has a role of preventing the ejected drug from adhering to the user's finger when ejecting the drug from the ejection hole 20, and after ejecting the drug from the ejection hole 20, the ejected drug is ejected from the ejection hole 20. It has a role of preventing the drug from dripping.

As shown in FIGS. 1A and 1B, the heights of the side walls 60a and 60b may be lower than the ejection hole 20 of the nozzle 21, and gradually taper from the tip of the plate-shaped member 60 toward the inside of the cap body 40. It may be made higher. In another example, the heights of the side walls 60a, 60b may extend to a position higher than the upper part of the nozzle 21, as shown in FIGS. 1C and 1D.

As shown in FIGS. 1C and 1D, by extending the heights of the side walls 60a and 60b to a position higher than the upper part of the nozzle 21, the side walls 60a and 60b are used when the erroneous injection prevention member 24 is cut off at the start of use. By contacting the upper part of the cap body 40 with the cap body 40, it is possible to prevent the nozzle 21 from directly contacting the cap body 40. With this structure, even when the thickness of the cap body 40 is reduced, the deformation of the cap body 40 can be prevented, so that the thickness of the cap body 40 can be reduced as compared with the conventional case.

In the following FIGS. 2A to 7, the case where the side walls 60a and 60b of the plate-shaped member 60 have the shapes shown in FIGS. 1A and 1B will be described as an example, but the side walls 60a and 60b in FIGS. 2A to 7B will be described.
