ABSTRACT:
TECHNICAL FIELD
The present invention relates to an aerosol spraying apparatus for spraying an aromatic, an insecticide, etc. Particularly, the present invention relates to an aerosol spraying apparatus suitable for use in a state in which it is installed on a floor etc.
BACKGROUND ART
Conventionally, there are proposed various aerosol spraying apparatuses. In the aerosol spraying apparatuses, there are an aerosol spraying apparatus of a type that an actuator is manually operated to spray an insecticide or the like, an aerosol spraying apparatus, from which an insecticide or the like is successively sprayed in a state where it is installed on a floor etc. (which is hereinafter referred to as “a whole-quantity sprayed type”), and so forth.
However, when an aerosol spraying apparatus is placed on a floor etc. and its actuator is manually operated, since a user must operate the actuator while stooping down over the aerosol spraying apparatus, it is inconvenient to use. Also, in this case, there is a possibility that aerosol contents such as an insecticide etc. can be sprayed toward the user and thus the user can inhale the aerosol contents. Especially, in the aerosol spraying apparatus of a whole-quantity sprayed type, this possibility is high. Also, there is proposed an aerosol spraying apparatus of a type that, for a given period of time after a user prepares an operation for spraying, the spraying of aerosol contents is not carried out, but the spraying of the aerosol contents can be started after the user leaves the room. However, since this type of aerosol spraying apparatus is large in size and is complicated in structure, manufacturing of such aerosol spraying apparatus is difficult and the manufacturing cost thereof is expensive. Further, a delay time from pressing down of a stem to spraying of the aerosol contents from the stem to the outside is liable to vary in every aerosol spraying apparatus. Furthermore, there is even a possibility that the aerosol contents cannot be sprayed actually.
It is an object of the present invention to provide an aerosol spraying apparatus which is compact in size and easy to handle, is capable of easy diffusion of aerosol contents, and is suitable for use in a state in which it is installed on a surface such as a floor etc.
DISCLOSURE OF THE INVENTION
The above object of the present invention can be achieved by an aerosol spraying apparatus which comprises an aerosol container including a stem provided with a stem opening for jetting aerosol contents, and an actuator which includes an operation portion for operating the stem, and a spray orifice communicated with the stem opening, the aerosol spraying apparatus characterized in that the operation portion and the spray orifice are arranged at different positions in order to prevent the aerosol contents to be sprayed from the spray orifice on operating the operation portion from being sprayed toward the operating position.
Here, the expression “the operation portion and the spray orifice are arranged at different positions” means that the operation portion and the spray orifice are arranged at the actuator in at least one of a manner that they are arranged at positions different from each other when viewed in the height direction of the aerosol spraying apparatus, and a manner that they are arranged at positions different from each other when viewed in a plan view of the aerosol spraying apparatus, so that the operation portion and the spray orifice are arranged at the actuator in such a manner as to satisfy one or the combination of those conditions, thereby being able to realize the effects of the present invention. The spray orifice is not limited to any special shape but includes not only a hole but also the end portion of guide means that guides the aerosol contents to be jetted out from the stem opening in a given direction.
According to the above aerosol spraying apparatus, while preventing the aerosol contents from being sprayed to the user, the whole quantity of the aerosol contents can be sprayed.
Further, the above object of the present invention can be achieved by an aerosol spraying apparatus which comprises an aerosol container including a stem provided with a stem opening for jetting aerosol contents, and, when in use, is installed through a bottom portion of the aerosol container, the aerosol spraying apparatus characterized in that slippage preventive means is disposed on the bottom portion of the aerosol container and prevents the aerosol spraying apparatus from slipping out of position on a surface onto which the aerosol spraying apparatus is installed.
In this aerosol spraying apparatus, it is preferable that an operation portion for operating the stem is further disposed. Also, as the operation portion, preferably, there may be employed a pedal which can be operated by treading it by foot.
According to such the aerosol spraying apparatus, when, in use, the aerosol container is installed on a surface such as a floor etc. and the stem is then operated, the slippage preventive means disposed on the bottom portion of the aerosol container can prevent the aerosol container from slipping out of position on the installation surface or falling down onto the installation surface. Accordingly, such the aerosol spraying apparatus is allowed to carry out its spraying operation easily, and is easy to use.
Further, the above object of the present invention can be achieved by an aerosol spraying apparatus which comprises an aerosol container including a stem provided with a stem opening for jetting aerosol contents, the aerosol spraying apparatus characterized in that the aerosol container has a shape hard to fall down, wherein the aerosol container is provided with a treading operation means including an operation portion which, when operated or trod by foot, can operate the stem, a spray orifice for spraying the aerosol contents to be jetted out from the stem at the time of the operation of the stem in a direction opposite to a direction toward a treading operation position in a plan view of the aerosol spraying apparatus, and a mounting portion which detachably retains the operation portion to one end of the aerosol container so that the operation portion covers the stem.
According to such the aerosol spraying apparatus, since the stem may be operated by the foot treading operation, a user does not need to stoop down. Also, the spraying direction of the aerosol contents is opposite to a direction toward the treading operation position. Therefore, the user may not inhale the aerosol contents. Here, the meaning of the expression “a direction opposite to a direction toward a treading operation position” comprises not only a direction along a line drawn so as to pass through the treading operation position in a plan view of the aerosol spraying apparatus but also a direction shifted in the range of 90° or less from the direction along above the line.
Further, the above object of the present invention can be achieved by an aerosol spraying apparatus which comprises an aerosol container including a stem provided with a stem opening for jetting aerosol contents, the aerosol spraying apparatus characterized in that the aerosol container has a shape hard to fall down, wherein the aerosol container is provided with a treading operation means including an operation portion which, when operated or trod by foot, can operate the stem, a spray orifice for spraying the aerosol contents to be jetted out from the stem at the time of the operation of the stem at an angle in the range of 30° to 85° with respect to an installation surface on which the aerosol container is placed and also in a direction opposite to a direction toward a treading operation position in a plan view of the aerosol spraying apparatus, and a mounting portion which detachably retains the operation portion to one end of the aerosol container so that the operation portion covers the stem.
According to such the aerosol spraying apparatus, since the spraying direction of the aerosol contents is not just above but a direction opposi
