<P>PROBLEM TO BE SOLVED: To provide an injection apparatus the cost of which as a product can be reduced although an object to be injected can be injected efficiently by means of the pressure of a gas from the injection apparatus. <P>SOLUTION: The injection apparatus 1 for injecting a liquid 11 to be housed therein by means of the pressure of the gas includes: a gas generator 2 for generating a predetermined amount of the gas when a start-up signal is inputted therein; and a container 3 for housing the object to be injected. The container 3 for housing the object to be injected has a storage chamber 5 having a liquid 11-housed housing bag 4 in-built and a gas discharge port 10 through which the gas to be generated from the gas generator 2 is discharged to the storage chamber 5. The storage chamber 5 is plugged by a mouth plug 6. An injection path 12 for communicating the inside of the storage chamber 5 to the outside is formed in the mouth plug 6. A breaking blade 7 for breaking the housing bag 4 is formed on the periphery of a storage chamber 5-side mouth part of the injection path 12. An inner wall portion of the storage chamber 5, which portion orbits the vicinity of the edge 7a of the breaking blade 7, is stuck circularly to the housing bag 4 to divide the storage chamber 5 into a gas discharge port 10-side portion and an injection path 12-side portion. <P>COPYRIGHT: (C)2011,JPO&INPIT |
