Applicators
First Claim
1. An applicator including:
- a reservoir for matter to be applied;
an applicator head comprising a chamber and elongate needle;
the needle being at least partially surrounded by a generally elongate proboscis mounted for axial movement over the needle;
at least one valving means being provided between the chamber and the needle;
further valving means being provided between the reservoir and the chamber;
triggering means being provided;
actuation of said triggering means causing matter to be applied to be passed from the reservoir into the chamber;
the proboscis being so mounted relative to the chamber and the needle, that on predetermined axial movement of the proboscis over the needle, at least an end of said needle is at least partially exposed and means between the chamber and needle is opened and means is provided to cause matter to pass from the chamber through said needle.

Abstract
The subject matter relates to an applicator for applying matter to be applied, such as vaccine, to animals. The applicator includes an applicator head which incorporates a chamber and needle. The needle is at least partially surrounded by a generally elongate proboscis or cover which is capable of axial movement over and relative to the needle. A reservoir for matter to be applied or vaccine, is provided and is attached to the applicator head. Valving connects the chamber with the needle and also connects the reservoir with the chamber. Predetermined axial movement of the proboscis or cover relative to the needle opens the valving between the needle and chamber and allows matter within the chamber, such as vaccine, to be passed from the chamber through the needle. The chamber is provided with a movable wall and actuating means connected to a trigger. On the trigger being actuated, the spring biased actuating means causes the movable wall of the chamber to move outwardly thereof, opening valving between the reservoir and chamber and drawing an amount of matter to be applied or vaccine into the chamber. A measure or shot of matter to be applied is then held in the chamber until the valve between the chamber and needle is opened on axial movement of the proboscis relative to the needle.

2. An applicator including:
-
a housing adapted to releasably locate a reservoir and applicator head; the applicator head including a chamber and needle; the needle being at least partially surrounded by a generally elongate proboscis capable of axial movement relative to the needle;
valving being provided between the chamber and the needle;further valving means being provided between the reservoir and the chamber; triggering means being provided; actuation of said triggering means causing matter to be applied to be passed from the reservoir into the chamber; the proboscis being so mounted relative to the chamber and needle, that on predetermined axial movement of the proboscis relative to the needle, valving means between the chamber and needle is opened and matter to be applied is caused to be passed from the chamber through the needle; the housing including an upper body portion capable of releasably locating the applicator head; a lower body support being spaced apart from the upper body portion so as to releasably locate the reservoir therebetween; the body further including a rear upper body portion and a handle portion defining a grip opening; triggering means being pivotally mounted to the handle portion, and means being provided to cause matter to be applied to pass from the chamber through said needle. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 15, 16)

- 32. An applicator comprising a head containing a chamber and an elongate hollow needle, said needle being fixed to the head and having one end adjacent the chamber, a generally elongate proboscis being mounted about and at least partially surrounding the needle and being adapted for axial movement over the needle, valve means being provided between said one end of the needle and the chamber, and being operable to provide communication between the chamber and the needle, said proboscis being so mounted relative to the chamber and needle that on predetermined axial movement of the proboscis rearwardly over the needle, by application of pressure to its forward end, the other end of the needle is at least partially exposed and said valve means opened and means being provided to cause a dosage to be applied to pass from the chamber through the needle when the valve means is opened.
-
36. A multiple dosage applicator comprising a head containing a chamber for receiving a dosage to be applied, and an elongate hollow needle being fixed to the head with one end adjacent the chamber, a generally elongate proboscis mounted about and at least partially surrounding the needle and being adapted for axial movement over the needle, valve means being provided between said one end of the needle and the chamber, and being operable to provide communication between the chamber and the needle so that on predetermined axial movement of the proboscis rearwardly over the needle, by application of pressure to its forward end, the other end of the needle is at least partially exposed and said valve means opened and means being provided to cause the dosage to be applied to pass from the chamber through the needle when the valve means is opened.
- 37. An applicator comprising an applicator head which includes a chamber and an elongate hollow needle, said needle having one end located adjacent the chamber, a generally elongate proboscis being mounted about the needle and being capable of axial rearward movement over the needle and relative to the chamber, valve means being provided between the needle and the chamber and being operable to provide communication between the needle and chamber, said proboscis being so mounted relative to the needle and chamber that predetermined axial movement of the proboscis rearwardly over the needle and relative to the chamber, by application of pressure to the forward end of the proboscis, at least partially exposes the other end of the said needle, said valve means between the chamber and needle being thereafter operable so as to permit passage of matter to be applied from the chamber through the needle, means being provided to cause said matter to pass from the chamber through the needle.
