Claims
- 1. A method of temporal sealing comprising the steps of positioning a sterilized lid on an opening of a container, the container being hung at a flange thereof on at least a pair of rails which are movable relative to one another such that a distance between said rails can be varied and partially pressing said sterilized lid onto at least a part of said flange with a heater and temporarily sealing said sterilized lid to at least part of said flange.
- 2. A temporal sealing means having a space for a sterilized lid that is to be placed onto a container, and at least one heater secured to move upwardly, downwardly and laterally in said space to press said sterilized lid against a flange on said container for temporal sealing.
- 3. A temporal sealing means having a space for a sterilized lid that is to be placed onto a container,
- and a pair of heaters secured to move upwardly and downwardly in said space to press said sterilized lid against a flange on said container for temporal sealing, said heaters being arranged such that a distance between the heaters can be varied according to the distance between a pair of rails which can freely be set for different sized containers.
- 4. A temporal sealing means having a space for a sterilized lid that is to be placed onto a container, at least one heater secured to move upwardly and downwardly in said space to press said sterilized lid against a flange on said container for temporal sealing, and
- a moving rod, a base end of which is rotatably secured to enable a top end thereof to be at a temporal sealing position, said at least one heater being secured to said top end.
- 5. A temporal sealing means as claimed in claim 4, further comprising a moving arm secured to the base end of said moving rod,
- and a device installed to said moving arm to move said moving rod upward and downward.
- 6. A temporal sealing means as claimed in claim 5 which comprises:
- a cam follower,
- a spring that gives elastic force to said moving arm in the upper direction,
- and a cam roller which is secured to a rotary axis, the cam roller intermittently rotating with intermittent movement of said container, a cam surface of said cam roller contacting said cam follower.
- 7. A temporal sealing means as claimed in claim 5 further comprising a cylinder that moves said moving arm upward and downward.
