Description

  The present invention relates to an injector such as a hair spray, in which an aerosol type or pump type injection device is assembled at the mouth of a container, and the contents of the container are injected to the outside through the stem by pushing the stem of the injection device. . Further, in such an injector, the present invention relates to an omnidirectional injection button unit in which a stem fitting portion is fitted to a stem and attached to an injection device at a container mouth so that the contents of the container can be injected in all directions.

  Conventionally, in an injector such as a hair spray, an aerosol type or pump type injection device is often assembled in the mouth of a container, and an injection button is attached to the stem of the injection device, and the injection button is pushed down. When the stem was pushed in, the contents in the container were ejected through the stem and ejected outward from the ejection port of the ejection button. However, with this type of injector, the direction of the injection hole is fixed, so depending on the injection target site, the injector must be used obliquely or upside down, resulting in poor usability. It was.

In order to solve such a problem, some conventional injectors have a spray pipe attached to the nozzle, and the spray pipe can be rotated 180 degrees vertically or 180 degrees horizontally. .

When the rotor cover 50 is rotated to the state shown in (A), the rotor 60 can be tilted vertically within a range of 180 degrees, and when the state shown in (B), the rotor 60 is set to a range of 180 degrees. It can fall down horizontally. That is, FIG. 8 shows a state where the rotor 60 is tilted downward in the state shown in FIG. In this way, by adjusting the degree of rotation of the rotor cover 60, the container contents can be ejected in all directions within a range of 360 degrees as shown in (C).

  In this example, the joint 30 and the rotor cover 50 are fitted with a certain amount of force to provide sliding resistance, so that the angle when the rotor 60 is rotated can be maintained. Yes. Further, a projection (not shown) is formed on the joint 30 side, and a key groove (not shown) is formed on the cap 20 side so that the projection enters, so that the joint 30 is not rotated when the rotor cover 50 is rotated. ing.

FIG. 10 shows a degassing state.
When degassing, put a finger on the finger hook 23, press the stem fitting portion 21 and push the stem 12, while rotating the gas vent tab 28 in the direction of the arrow to hold the stem 12 in the pushed state. The contents remaining in the container 10 are completely jetted.

  By the way, in the above-described example, the injection device opens the valve by pushing the stem 12, and the container contents are put into the injection passage 25 from the communication passage 24 through the stem 12 by the pressure of the propellant in the container 10, and flexible. The case of an aerosol type spraying outward from the tip of the conductive pipe 40 has been described, but the spraying device reciprocates the piston by pushing the stem and releasing the pushing, and the container contents are The same can be applied to a pump type in which the pump is once pumped into the pump chamber and then injected to the outside through the stem.
