Description

Trigger type aerosol device and aerosol cap

The application is a divisional application of invention patent applications with the name of 'trigger type aerosol device and aerosol cap', international application date of 2017, 4 months and 27 days, international application number of PCT/JP2017/016758 and national application number of 201780041006.5.

Technical Field

The present invention relates to trigger aerosol devices, and more particularly to aerosol caps for large volume trigger aerosol containers.

Background

In a conventional trigger type aerosol device, in a case where an aerosol cap is mounted on an aerosol container of a relatively small capacity, a user can sufficiently support the weight of the aerosol device by holding a trigger portion of the aerosol cap with only one hand. However, when the conventional aerosol cap is used by being attached to an aerosol container having a relatively large capacity, the weight of the aerosol device cannot be sufficiently supported by holding the trigger portion of the aerosol cap with only one hand, and the operation of triggering becomes difficult.

In addition, in both of the aerosol bodies having a relatively small volume and the aerosol bodies having a relatively large volume, when the aerosol bodies are ejected for a long time, the can needs to be held for a long time in order to be operated by one hand, and there is a problem in that the operation of the trigger becomes difficult.

In addition, in the case of a user who does not have a grip strength for supporting the weight of the aerosol device, such as a child, a woman, and an old person, the aerosol device needs to be supported by the other hand, and there is an inconvenience that both hands are occupied when using the aerosol container.

For example, in the case of the aerosol type atomizer described in patent document 1, the user needs to hold the peripheral wall of the cap and the upper part of the aerosol can with the other fingers and palm while putting the index finger on the trigger part, and to support the weight of the aerosol device. When the index finger is separated during the trigger operation, the burden of supporting the weight of the aerosol device by another finger or palm increases. Therefore, it is difficult to support the weight of the aerosol can having a large capacity with only one hand and to perform ejection for a long time, and the cap portion of the aerosol type atomizer described in patent document 1 is not suitable for supporting the weight of the aerosol device having a large capacity and performing ejection for a long time.

Disclosure of Invention

Problems to be solved by the invention

In order to solve such a problem, in the trigger-type dispenser described in patent document 2, a locking surface for locking an upper surface of a hand holding the grip portion to the mounting cap is provided on a lower surface of a plate-shaped portion provided to protrude rearward from a lower surface of a rear portion of the mounting cap. However, since the plate-like portion is provided only at the rear portion of the mounting cap and has a small area for locking the upper surface of the hand, the weight of the container body is mainly supported by the grip of the grip portion. That is, the plate-like portion can serve as a hand-slip stopper, but is not suitable for supporting the weight of a large-capacity aerosol device and for spraying over a long period of time.

In the trigger type liquid sprayer of patent document 3, the lower end portion and the rear portion of the main body cover are formed in a bulging shape, but the main body cover is covered only on the upper portion of the sprayer main body, and is not suitable for supporting the weight of a large-capacity aerosol device. Further, even if the trigger is gripped as if the back of the hand were hooked on the bulged portion of the main body cover of patent document 3, the lower end portion of the main body cover would be caught in the back of the hand because the lower end portion and the back of the hand are in contact with each other by a wire, and therefore, the trigger is not suitable for supporting the weight of a large-capacity aerosol container.

As described above, the aerosol cap used in the conventional trigger type aerosol device has a problem that it is not suitable for performing a trigger operation while supporting the weight of the aerosol device having a large capacity.

Accordingly, the present invention provides an aerosol cap that can support the weight of a large-capacity aerosol device by holding the trigger portion of the aerosol cap with only one hand even when the aerosol cap is mounted on a large-capacity aerosol container, and an aerosol device including the aerosol cap that solve the above-described problems.

Detailed Description

Preferred mode for carrying out the invention

Example 1

Fig. 1A and 1B are perspective views showing an aerosol cap 1 according to embodiment 1 of the present invention. An aerosol cap 1 according to the present invention includes a nozzle 21 having a discharge hole 20 for discharging a fluid in an aerosol container, a stem 30 integrated with the nozzle 21 or engaged with the nozzle 21, and a cap body 40 covering the nozzle 21 and the stem 30, wherein the cap body 40 has blade portions 50 protruding from at least a side surface portion 41 of the cap body 40. The cap body 40 preferably has blade portions 50 protruding from the side surface portion 41 of the cap body 40 and the rear portion 42 of the cap body 40, as shown in fig. 1A and 1B. However, the blade portions 50 may protrude only from the side surface portions 41 of the cap body 40 without protruding from the rear portion 42 of the cap body 40.

In addition, the cap body 40 is provided with an erroneous injection prevention member 24 for preventing erroneous injection. If the erroneous ejection prevention member 24 is detached from the cap body 40, ejection is possible. The erroneous ejection prevention member 24 is coupled to the nozzle 21. The erroneous ejection prevention member 24 is preferably connected to the nozzle 21 at one location, but is not limited thereto, and may be connected to a plurality of locations.

The cap body 40 has a ridge portion 70 protruding from the side surface portion 41 of the cap body 40. The bulge 70 does not protrude from the rear portion 42 of the cap body 40 unlike the blade 50. The bulge portion 70 is provided at a position lower than the blade portion 50. The side surface portion 41 of the cap body 40 may protrude from any position of the side surface portion 41, as long as the side surface portion is located below the blade portion 50. The bulge portion 70 is provided at a distance from the blade portion 50 so that a user can hold between the bulge portion 70 and the blade portion 50 with fingers. By forming the depressions by the blade portions 50 and the raised portions 70 of the cap body 40, the user can also expect an improved feeling of stability and use when holding the cap body 40.

As shown in the use example of fig. 7, the aerosol cap 1 is mounted on an upper portion of an aerosol container 2 containing a liquid medicine, and constitutes an aerosol device 10. The user holds the aerosol cap 1 with his or her hand and holds the index finger on the stem 30, thereby ejecting the medicine contained in the aerosol container 2 from the ejection hole 20 of the nozzle 21.

When the user holds the aerosol cap 1 with the hand by placing the index finger on the stem 30, the lower surface of the blade 50 is in contact with the upper surface side of the index finger and the thumb or the back of the hand at the root of the index finger and the thumb.

And the function of preventing the medicine from dripping from the ejection hole 20 after the medicine is ejected from the ejection hole 20.

The plate-like member 60 may have

side walls

60a and 60b extending substantially vertically from both side ends of the plate-like member 60. The

side walls

60a, 60b may be integral with the plate-like member 60 or may be attached to the plate-like member 60. The height of the side walls 60a and 60B may be lower than the discharge hole 20 of the nozzle 21 as shown in fig. 1A and 1B, or may gradually increase from the tip of the plate-like member 60 toward the inside of the cap body 40. In another example, the

side walls

60a and 60b may extend to a height higher than the upper portion of the nozzle 21 as shown in fig. 1C and 1D.

As shown in fig. 1C and 1D, by extending the height of the

side walls

60a and 60b to a position higher than the upper portion of the nozzle 21, when the erroneous ejection preventing member 24 is cut off at the start of use, the upper portions of the

side walls

60a and 60b contact the cap body 40, and the nozzle 21 and the cap body 40 can be prevented from directly contacting each other. According to 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 one.

Note that, although fig. 2A to 7 below describe a case where the side walls 60a and 60B of the plate-like member 60 have the shapes shown in fig. 1A and 1B as an example, the shapes other than the side walls 60a and 60B in fig. 2A to 7 and the following description of fig. 2A to 7 are also used when the side walls 60a and 60B of the plate-like member 60 have the shapes shown in fig. 1C and 1D.

Fig. 2A is a right side view of the aerosol cap 1 according to the first embodiment of the present invention, and fig. 2B is a left side view of the aerosol cap 1 according to the first embodiment of the present invention. Here, the end point of the paddle 50 on the discharge hole 20 side is defined as a front end point 51, and the end point of the paddle 50 on the opposite side from the discharge hole 20 is defined as a rear end point 53. Typically, the front end point 51 is provided at a position higher than the rear end point 53 in the vertical direction, and the blade 50 forms a curved surface connecting the front end point 51 and the rear end point 53. The curved surface of the blade 50 has a lowest point 52 at a position lowest in the vertical direction of the curved surface. The lowermost point 52 is disposed between the front end point 51 and the rear end point 53.

The lowermost point 52 of the blade 50 may be provided at a position lower than the top of the cap body 40 and higher than the lower end 31 of the rod 30 in the vertical direction. For example, the lowermost point 52 may be set to a position lower than the position 10mm higher in the vertical direction than the center point 22 of the discharge hole 20 when the erroneous spray prevention member 24 is removed and the aerosol cap 1 and the stem 23 are engaged with each other, and higher than the lower end 31 of the stem 30. The lowermost point 52 is preferably set to a position 5 to 20mm lower than the center point 22 of the discharge hole 20 of the nozzle 21 in the vertical direction, and more preferably set to a position 5 to 15mm lower than the center point 22 of the discharge hole 20 of the nozzle 21 in the vertical direction.

Thus, when the user holds the lever 30, the lower surface of the blade 50 is in contact with the upper surfaces of the index finger and the thumb or the back of the hand at the root portion of the index finger and the thumb. The weight of the aerosol device can be supported by the contact surface between the user's hand and the lower surface of the blade 50. Thus, the user can support the weight of the aerosol device not only by the grip of the aerosol cap and the aerosol container but also by the surface contacting the lower surface of the blade portion 50.

The lowermost point 52 of the blade 50 is typically located rearwardly of the center of gravity of the aerosol apparatus. Thus, the weight of the aerosol device is applied not to the fingertip of the user but to the base side of the index finger and the thumb, and the lever 30 can be easily operated by the index finger, thereby achieving an effect of stably supporting the weight of the aerosol device.

Fig. 3A is a front view of the aerosol cap 1 according to the first embodiment of the present invention, and fig. 3B is a rear view of the aerosol cap 1 according to the first embodiment of the present invention. The front end 51 of the vane 50 is typically disposed vertically higher than the center point 22 of the discharge hole 20 of the nozzle 21. The front end 51 is preferably provided at a position vertically higher by 5mm or more than the center point 22 of the discharge hole 20 of the nozzle 21, but the front end 51 may be provided at any position vertically lower than the top of the cap body 40 and higher than the lower end 31 of the rod 30 without impairing the operability of the fingers.

The rear end 53 of the vane 50 is typically provided at a position lower than the center point 22 of the discharge hole 20 of the nozzle 21 in the vertical direction. The rear end point 53 is preferably provided at a position 5 to 20mm lower than the center point 22 of the discharge hole 20 of the nozzle 21 in the vertical direction, more preferably at a position 5 to 15mm lower, but the present invention is not limited thereto, and the rear end point 53 may be provided at any position lower than the top of the cap body 40 and higher than the lower end portion 31 of the rod 30 in the vertical direction.

Fig. 4A is a cross-sectional view taken along line IV-IV of fig. 3A. As shown in fig. 4A, the lever 30 is integrated with the nozzle 21 or engaged with the nozzle 21 inside the cap body 40. Fig. 4B is a cross-sectional view taken along line IV-IV of fig. 3A when the erroneous injection preventing member is removed.

Fig. 5A is a plan view of the aerosol cap 1 according to the first embodiment of the present invention as viewed from above, and fig. 5B is a bottom view of the aerosol cap 1 according to the first embodiment of the present invention as viewed from below. Here, a point of the blade 50 which most protrudes in the right direction of fig. 5A is referred to as a right end point 54, and a point which most protrudes in the left direction of fig. 5A is referred to as a left end point 55. The right end 54 of the vane 50 is arranged only in the right direction of the width W1 from the center point 22 of the discharge hole 20 of the nozzle 21. The width W1 is preferably 25mm or more, but is not limited thereto, and the width W1 may be 10mm to 50mm.

Similarly, the left end 55 of the vane 50 is disposed only in the left direction of the width W2 from the center point 22 of the discharge hole 20 of the nozzle 21. The width W2 is preferably 25mm or more, but is not limited thereto, and the width W2 may be 10mm to 50mm.

The width W1 and the width W2 are typically the same in size, but the width W1 and the width W2 may be different widths.

The bulge 70 of the cap body 40 protrudes from the side surface portion 41, but the right end point 54 and the left end point 55 of the blade 50 of the cap body 40 protrude from the bulge 70 of the cap body 40. That is, the width W1 and the width W2 are larger than the width of the protuberance 70 of the cap body 40 protruding in the rightward direction and the width protruding in the leftward direction, respectively.

Here, when a portion of the rear portion 42 of the cap body 40 that is lower than the blade portion 50 is defined as the rear wall portion 56, the rear end point 53 of the blade portion 50 protrudes rearward from the rear wall portion 56 by the width W3. The width W3 is preferably 5 to 15mm, but is not limited thereto, and may be 5 to 50mm.

The blade 50 is formed into a curved surface, and as shown in fig. 5A and 5B, the portion of the blade 50 protruding from the side surface portion 41 and the portion protruding from the rear portion 42 are integrally formed into the same curved surface.

Fig. 6 is a cross-sectional view taken along line VI-VI of fig. 5A. The thickness of the blade 50 is typically tapered as it protrudes outward, but the present invention is not limited thereto, and the blade 50 may have a constant thickness. The thickness of the thickest part of the blade part 50 is typically 1 to 5mm, but the thickness is not limited thereto, and may be any thickness that can be formed and does not deform under load.

Fig. 7 is a diagram showing an example of use of an aerosol apparatus 10 in which an aerosol cap 1 according to a first embodiment of the present invention is attached to an aerosol container 2. As shown in fig. 7, when the user holds the index finger on the lever 30, the lower surface of the blade 50 is in contact with the upper surfaces of the index finger and the thumb of the user or the back of the hand at the root portion of the index finger and the thumb. The weight of the aerosol apparatus 10 can be supported by this lower surface that is in contact with the user's hand. This reduces the grip for holding the cap body 40 or the aerosol container 2 and supporting the weight of the aerosol device 10.

Example 2

Fig. 8A and 8B are perspective views showing an aerosol cap according to a second embodiment of the present invention. In the second embodiment, the shape of the blade 150 is different from the shape of the blade 50 of the first embodiment. As for other points, since the same as the first embodiment, the explanation is omitted here.

While the blade portions 50 of the first embodiment protrude over the entire rear portion 42 and side surface portion 41 of the cap body, the blade portions 150 of the second embodiment protrude over the rear portion from the middle of the rear portion 42 and side surface portion 41 of the cap body.

Fig. 8C and 8D are perspective views showing another example of an aerosol cap according to a second embodiment of the present invention, and show an example in which the

side walls

60a and 60b of the plate-like member 60 extending substantially vertically from both side end portions extend to a position higher than the upper portion of the nozzle 21, as in fig. 1C and 1D.

In addition, in the following fig. 9A to 14, a case where the side walls 60a and 60B of the plate-like member 60 have the shapes shown in fig. 8A and 8B is described as an example, but shapes other than the side walls 60a and 60B in fig. 9A to 14 and the following description of fig. 9A to 14 are also adopted in the same manner in a case where the side walls 60a and 60B of the plate-like member 60 have the shapes shown in fig. 8C and 8D.

Fig. 9A is a right side view and fig. 9B is a left side view of an aerosol cap according to a second embodiment of the present invention. Here, the end of the vane 150 of the second embodiment on the side of the discharge hole 20 is defined as a front end 151, and the end of the vane 150 on the opposite side of the discharge hole 20 is defined as a rear end 153. Typically, the front end point 151 is provided at a position higher than the rear end point 153 in the vertical direction, but the front end point 151 and the rear end point 153 may be substantially at the same height, or the rear end point 153 may be provided at a position higher than the front end point 151. The blade 150 forms a curved surface connecting the front end 151 and the rear end 153. The curved surface of the blade 150 has a point at which the position in the vertical direction of the curved surface is the lowest as the lowest point 152. The lowermost point 152 is disposed between the forward end point 151 and the rearward end point 153.

The lowermost point 152 of the blade 150 may be provided at a position lower than the top of the cap body 40 and higher than the lower end 31 of the rod 30 in the vertical direction. For example, the lowermost point 152 may be set to a position lower than the position 10mm higher in the vertical direction than the center point 22 of the discharge hole 20 when the erroneous spray prevention member 24 is removed and the aerosol cap 1 and the stem 23 are engaged with each other, and higher than the lower end 31 of the stem 30. The lowermost point 152 is preferably set to a position 5 to 20mm lower than the center point 22 of the discharge hole 20 of the nozzle 21 in the vertical direction, and more preferably set to a position 5 to 15mm lower than the center point 22 of the discharge hole 20 of the nozzle 21 in the vertical direction.

Thus, when the user holds the lever 30, the lower surface contact of the blade 150 is in contact with the upper surfaces of the index finger and the thumb or the back of the hand of the root portion of the index finger and the thumb. The weight of the aerosol container can be supported by the face of the user's hand in contact with the underside of the blade 150. Thus, the user can support the weight of the aerosol device not only by the grip of the aerosol cap and the aerosol container but also by the surface contacting the lower surfaces of the blade portions 150.

The lowermost point 152 of the blade 150 is typically located rearwardly of the center of gravity of the aerosol device. Thus, the weight of the aerosol device is applied not to the fingertips of the user but to the base side of the index finger and the thumb, and the lever 30 can be easily operated by the index finger, thereby providing an effect that the aerosol container can be stably supported.

Fig. 10A is a front view of the aerosol cap 1 according to the second embodiment of the present invention, and fig. 10B is a rear view of the aerosol cap 1 according to the second embodiment of the present invention. The front end 151 of the vane 150 is typically disposed vertically below the center point 22 of the discharge hole 20 of the nozzle 21. The front end point 151 is preferably provided at a position 5 to 20mm lower than the center point 22 of the discharge hole 20 of the nozzle 21 in the vertical direction, more preferably at a position 5 to 15mm lower, but the front end point 151 may be provided at any position lower than the top of the cap body 40 and higher than the lower end 31 of the rod 30 in the vertical direction without impairing the operability of fingers.

The rear end 153 of the vane portion 150 is typically provided at a position lower than the center point 22 of the discharge hole 20 of the nozzle 21 in the vertical direction. The rear end point 153 is preferably provided at a position lower than the center point 22 of the discharge hole 20 of the nozzle 21 by 5 to 20mm in the vertical direction, more preferably by 5 to 15mm, but the rear end point 153 is not limited thereto, and may be provided at a position lower than the top of the cap body 40 and higher than the lower end 31 of the rod 30 in the vertical direction.

Fig. 11A is a cross-sectional view taken along line XI-XI of fig. 10A. As shown in fig. 11A, the lever 30 is integrated with the nozzle 21 or engaged with the nozzle 21 inside the cap body 40. Fig. 11B is a cross-sectional view taken along line XI-XI in fig. 10A when the erroneous ejection preventing member is removed.

Fig. 12A is a plan view of the aerosol cap according to the second embodiment of the present invention as viewed from above, and fig. 12B is a bottom view of the aerosol cap according to the second embodiment of the present invention as viewed from below. As shown in fig. 12A, the blade 150 of the aerosol cap 1 according to the second embodiment may have a substantially fan shape when viewed from above. Here, a point of the blade portion 150 most protruding in the right direction of fig. 12A is referred to as a right end point 154, and a point most protruding in the left direction of fig. 12A is referred to as a left end point 155. The right end 154 of the vane 150 is disposed only in the right direction of the width W11 from the center point 22 of the discharge hole 20 of the nozzle 21. The width W11 is preferably 25mm or more, but not limited thereto, and the width W11 may be 10mm to 50mm.

Similarly, the left end 155 of the vane 150 is disposed only in the left direction of the width W12 from the center point 22 of the discharge hole 20 of the nozzle 21. The width W12 is preferably 25mm or more, but is not limited thereto, and the width W12 may be 10mm to 50mm.

The width W11 and the width W12 are typically the same, but the width W11 and the width W12 may be different widths.

The bulge 70 of the cap body 40 protrudes from the side surface portion 41, but the right end point 154 and the left end point 155 of the blade 150 of the cap body 40 protrude from the bulge 70 of the cap body 40. That is, the width W11 and the width W12 are larger than the width of the protuberance 70 of the cap body 40 protruding in the rightward direction and the width protruding in the leftward direction, respectively.

Here, when a portion of the rear portion 42 of the cap body 40 that is lower than the blade portion 150 is defined as the rear wall portion 156, the rear end point 153 of the blade portion 150 protrudes rearward from the rear wall portion 156 by the width W13. The width W13 is preferably 5 to 15mm, but is not limited thereto, and may be 5 to 50mm.

The blade 150 is formed into a curved surface, and as shown in fig. 12A and 12B, the portion of the blade 150 protruding from the side surface portion 41 and the portion protruding from the rear portion 42 are integrally formed into the same curved surface.

Fig. 13 is a cross-sectional view taken along line XIII-XIII of fig. 12A. The thickness of the blade portion 150 is typically tapered as it protrudes outward, but the present invention is not limited thereto, and the blade portion 150 may have a constant thickness. The thickness of the thickest part of the blade part 150 is typically 1 to 5mm, but the thickness is not limited thereto, and may be any thickness that can be formed and does not deform under load.

Fig. 14 is a diagram showing an example of use of an aerosol device 10 in which an aerosol cap 1 according to a second embodiment of the present invention is attached to an aerosol container 2. As shown in fig. 14, when the user holds the index finger on the lever 30, the lower surface of the blade 150 is in contact with the upper surfaces of the index finger and the thumb of the user or the back of the hand at the root portion of the index finger and the thumb. The weight of the aerosol apparatus 10 can be supported by this underlying surface that is in contact with the user's hand. This reduces the grip for holding the cap body 40 or the aerosol container 2 to support the weight of the aerosol device 10.

The above description is made for the embodiments, but the present invention is not limited thereto, and it is apparent to those skilled in the art that various changes and modifications can be made within the spirit of the present invention and the scope of the appended claims.
