Description

Aerosol Sprayer {AEROSOL SPRAYER}

The present invention relates to an aerosol sprayer which is configured to spray the contents of a drug or the like contained therein to the outside by an operation of the spray operation means.

Conventionally, an aerosol sprayer has a cylindrical body part, a lower cover, and a top cover, and has a container for accommodating contents such as a medicine therein, and is equipped with a cap having an injection port and an injection button on the upper part of the container. If used by the user, hold the top of the container with the thumb, middle finger, ring finger, and little finger, and spray the contents inside the container from the jet by pressing the jet button of the cap with the index finger while pointing the jet toward the object. It was.

On the other hand, in the container of an aerosol atomizer, the content of it is made into 300 ml or more concretely in consideration of the frequency | count of use, the use situation, etc., and for this reason, handling is cumbersome or bad when it is placed In accordance with the problem to be solved, the enlargement is usually performed only in the radial direction of the body portion without greatly expanding the height direction of the body portion of the container, so that the maximum diameter portion of the body portion is usually 50 mm or more.

In the container of the conventional aerosol nebulizer, the diameter direction of the main body was enlarged to secure the contents, and the maximum diameter was 50 mm or more. Therefore, when the user uses the container, the container is formed with the thumb, the middle finger, the ring finger, and the little finger. There is a problem that it is very difficult to maintain, that is, very difficult to hold the container, the problem that the aerosol sprayer slips off the hand when wet or sweaty rain. In addition, since the diameter of the main body portion in the container is large, the middle finger widens, and the index finger does not move as the middle finger widens, making it difficult to easily press the ejection button on the cap by the index finger. A problem occurred.

The present invention aims to solve the above problems.

One embodiment of the present invention,

It consists of a cylindrical body part, a lower cover, and an upper cover to accommodate contents such as drugs inside, and at the same time, the maximum diameter of the body part is 50 mm or more, and a portion from the upper end of the body part to 10 mm or more from the upper part is directed upward. The container which made the diameter of the upper end of a main body part 70 to 90% of the largest diameter part as this diameter reduction part which becomes small,

It is an aerosol nebulizer which is attached to the upper part of the container, and which is equipped with an injection port and an injection operation means, and which consists of a cap which injects the contents inside the container from the injection hole by operating this injection operation means.

According to the above-described configuration, the user can reduce the diameter of the upper portion of the main body in the container held by the thumb, middle finger and ring finger and the little finger, and facilitate the container by the thumb, middle finger and ring finger and the little finger. It can make it easy to hold | maintain, ie, hold a container.

In the above-mentioned configuration, it is preferable to form the diameter reduction portion of the main body portion in the container in a step shape.

According to such a structure, the thumb, middle finger, ring finger, and little finger can be improved by the irregularities of the diameter-reducing portion which becomes a step shape.

According to the studies of the inventors of the present invention, in the container of the aerosol sprayer, a portion of the upper portion of the upper portion of the upper portion of the upper portion of the upper portion of the main body portion is 10 mm or more from the lower side, preferably 30 mm or more. By setting the diameter to 70 to 90% of the maximum diameter of the main body, the container can be easily held by the user's thumb, middle finger, ring finger, and little finger, that is, the container can be easily held, and it can be wet or sweated in the rain. It has been found that even in the state can be eliminated slipping off the hand or the disadvantage of difficult to press the eject button of the cap.

As an aerosol atomizer, as shown in FIG. 1, the container 1 which accommodates contents, such as a chemical | medical agent, is mounted in the inside of this container 1, and the inside of the container 1 is mounted in the upper part of this container 1 from the injection port 12. As shown in FIG. It consists of a cap 2 to inject.

The container 1 is provided with a longitudinally cylindrical body portion 3, the lower lid 4 is fixed to the lower portion of the body portion 3, and the upper lid 5 is fixed to the upper portion, and the upper portion is The valve 6 is attached to the center of the lid 5, and the tube 7 for sucking up the contents inside the container 1 which is the lower part of this valve 6 is attached.

And when the main-body part 3 makes the largest diameter part 50 mm or more, specifically, the maximum diameter part is 60 mm or 65 mm, and makes the maximum diameter part 60 mm, the height of the main body part 3 is 152 mm. If the content is 385 ml, and the maximum diameter is 65 mm, the height of the main body 3 is 195 mm, the content is 580 ml, and the content in the container 1 is 300. It can be made more than ml. In the main body part 3 comprised in this way, the diameter reduction part 8 which diameter becomes small toward the upper part is made into the part from the upper end to 10 mm or more of lower side, for example, from the upper end to 30 mm below, and this diameter reduction part ( 8) is formed in a five step shape. Thereby, even when the largest diameter part of the main-body part 3 is 60 mm or 65 mm, the diameter of the upper end can be made into 70 to 90% of the largest diameter part of a main-body part.

In addition, the upper lid 5 has a mountain cup 9 formed in a ring shape while being formed in a shape in which air is almost overturned, and bent at a peripheral edge portion thereof. Moreover, it is preferable that the height from the lower end in this upper lid 5 to the upper mountain cup 9 shall be in the range of 7-15 mm.

On the other hand, the cap 2 has a frame 10 which is coupled to the mountain cup 9 of the upper lid 5 of the container 1, and has an injection hole 12 and injection operation means inside the frame 10. The movable body 11 which has the 13 is attached so that it can rock freely up and down.

In the movable body 11, a passage 14 communicating with the valve 6 is formed therein, and the injection port 12 communicating with the upper end of the passage 14 and directed in the horizontal direction is vertically formed. At the same time, the injection button 13A, which is the injection operation means 13, is formed and the valve 6 attached to the upper cover of the container 1 is opened by pressing the injection button 13A downward. Accordingly, the contents inside the container 1 are injected from the injection port 12 to the outside through the valve 6.

Thus, in the main-body part 3 of the container 1, the diameter of the upper end of a main-body part is maximized by making into the diameter reduction part 8 which diameter becomes small upward from the upper part to the lower part 10 mm. By setting it as 70-90% of a diameter part, the diameter of the upper end of the main-body part 3 in the container 1 which a user hold | maintains with a thumb and a middle finger can be made small, especially in the main-body part 3 If the portion from the upper end to the diameter-reducing portion 8 to 30 mm or more is used as the diameter reducing portion 8, the diameter of the upper portion of the main body portion 3 in the container 1 held by the thumb, the middle finger, the ring finger and the little finger can be reduced. The container 1 can be easily held by the thumb, the middle finger, the ring finger and the little finger, and the container 1 can be easily held. As a result, it is possible to eliminate the case where the container slips off the hand even in the state of being wet with rain or sweating. In addition, by reducing the diameter of the upper end and the upper part of the main body 3 in the container 1, the middle finger does not open greatly, and the index finger does not move as the middle finger widens, thereby eliminating the forceps. The operation of pushing the injection button 13A in the cap by the finger can be easily performed.

Moreover, the diameter of the upper end of a main body part is made into the diameter reduction part 8 which diameter becomes small toward the upper side from the upper end of the main body part 3 in the container 1 to 10 mm or more of lower sides. By setting it as 70 to 90%, the diameter of the upper end of both main-body parts 3 can be unified to the same dimension, for example, when having set the maximum diameter part of the main-body part 3 to 60 mm, and setting it to 65 mm. . Therefore, when the overcap which covers the whole cap 2 which prevents the malfunction at the time of not using the aerosol atomizer is provided so that the upper end of the main-body part 3 in the container 1 can be attached or detached freely, the maximum In the case of 60 mm in diameter and 65 mm in diameter, in the past, separate over caps were prepared and a plurality of types of over caps were required to attach them. However, in the present invention, the over caps can be the same. In other words, it can be shared, and the cost can be greatly reduced.

In addition, the aerosol sprayer which concerns on this invention is not limited only to the above-mentioned, It can change suitably within the range which does not deviate from the summary of this invention.

For example, in the above-mentioned atomizer, although the diameter reduction part 8 of the upper part of the main-body part 3 in the container 1 is formed in five steps of steps, although not shown in figure, it is two steps It may be formed in a stair shape of 4 to 6 steps, or more than 6 steps, and as shown in Fig. 2, instead of forming the diameter reducing part 8 in a step shape, it may be formed in a tapered shape that becomes an inclined straight line. The tapered portion may also be curved, in addition to being straight.

In addition, instead of forming two injection holes 12 formed in the movable body 11 in the cap 2 vertically, you may use one or three or more.

In addition, in the movable body 11 in this cap 2, although it was a push button type injection button 13A as injection operation means 13, as shown in FIG. 3, trigger type injection instead. The lever 13B may be used. In this way, when the triggered injection lever 13B is used, the index finger for operating the injection lever 13B is in a horizontal direction near the stop for holding the container 1, so that the upper end of the container held at the stop, For example, operation of the injection lever 13B while maintaining the container 1 very easily only by making the diameter reduction part 8 which becomes a 3 step | step-shaped part of the lower part 10 mm from the upper end of the main-body part 3 is easy. This can be done very easily without disturbing this stop. In addition, the shape of the diameter reduction part 8 is not limited to what was mentioned above.

In addition, in the container 1, as the contents contained therein, various materials such as paints as well as drugs such as insecticides and fragrances can be used.

Next, the effect of the aerosol sprayer which concerns on this invention is demonstrated as an experiment example.
