Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol container having a trigger type injection nozzle for ejecting a liquid content filled in a container body by pulling a trigger.

[0002]

2. Description of the Related Art As shown in FIG. 3, a conventional aerosol container 51 includes a container body 55 including a cylindrical body 52, a canopy 53 and a bottom cover 54, and a valve 5 engaged with the canopy 53.
6 and an actuator 59 having an injection nozzle 58 inserted into the stem 57 of the valve 56, and a system in which the actuator 59 is pushed down to inject the content liquid is general. The aerosol container 51 of this form is used in many fields such as pharmaceuticals, cosmetics, household products and foods.

On the other hand, in recent years, a trigger type injection nozzle for ejecting the content liquid filled in the container main body by pulling a trigger for the reason that the content liquid is easily ejected and the directivity of the ejection direction is good. Many things that have been prepared have been used. As shown in FIG. 4, an aerosol container 61 equipped with this trigger type injection nozzle has a container body 65 composed of a cylindrical body portion 62, a canopy 63 and a bottom lid 64.
A valve (not shown) engaged with a bead formed in the opening of the canopy 63, and a trigger type injection nozzle 66 fitted to the outer periphery of the valve.

However, when the trigger type injection nozzle 66 is used in the conventional aerosol container main body 65, for example, in an aerosol container filled with a content liquid which is inexpensive and requires a relatively large internal volume, such as an insecticide, It is necessary to increase the outer diameter of the container body 65 in order to secure the necessary internal volume. Therefore, when the aerosol container 61 is gripped by hand in order to use it, as shown in FIG. 4, since the diameter of the container container 65 is large, the container container 65 must be gripped with the thumb and middle finger spread out. Therefore, the index finger is hard to reach the trigger portion 64, and the trigger is difficult to pull.

In such a case, it is conceivable to reduce the outer diameter of the container body in order to easily pull the trigger.
However, if the outer diameter of the container body is simply reduced, it is necessary to increase the height of the container body in order to secure the necessary internal volume, and therefore the product will not sit well. There is also a problem that a line separate from the conventional container manufacturing line must be provided. On the contrary, if the content amount is reduced, there is no problem with expensive and low consumption items such as cosmetics,
When used for cheap and high consumption items such as insecticides, the content liquid will be consumed immediately, so it is more costly with an aerosol container equipped with a trigger type injection nozzle that is more expensive than the actuator type. Inconvenience that the value becomes high occurs.

[0006]

SUMMARY OF THE INVENTION The present invention aims to improve an aerosol container, and more specifically, to solve the above-mentioned inconvenience, without reducing the inner volume of the aerosol container having a trigger type injection nozzle. The purpose is to improve the gripping property.

[0007]

In order to achieve the above object, the aerosol container of the present invention has a trigger type injection nozzle for ejecting the content liquid filled in the container body by pulling a trigger. In the aerosol container provided at the upper end, in the state where the upper part of the container body has a smaller diameter than the lower part of the container body and the trigger can be operated, put a finger on the trigger and grasp the container body with another finger. It is characterized in that it is provided with a gripping part.

[0008]

According to the aerosol container of the present invention, since the upper portion of the container main body is provided with the grip portion having a diameter smaller than that of the lower portion thereof, a finger is put on the trigger in a state in which the trigger can be operated and another finger The container body can be gripped with.
