Definitions
- the present invention relates to, for example, a container ultrasonic sealing method for sealing a lid, a stopper, and other container components on a container body using an ultrasonic sealing device.
- a container component is sealed in a container body using an ultrasonic horn having a sealing action surface.
- the sealed portion is pressurized with a seal working surface, and an ultrasonic reciprocating vibration in an axial direction parallel to the pressing direction is applied to the seal working surface.
- the ultrasonic reciprocating vibration applied to the ultrasonic horn acts so as to hit the sealed surface of the container, and this travels along the container wall and the head space in the container. To vibrate the contents of the container. Doing so can cause the contents to burst, or, if the contents are liquid, to violently shake the liquid or to atomize under certain conditions. It could erupt. To prevent this, use a head space inside the container. It was necessary to take more.
- the conditions for obtaining a good seal are narrowly limited, and if the seal conditions are not satisfied, the thin part of the container component may be broken or pinholes may be generated in the seal part. Become.
- Heat sealing is not efficient because it takes a long time to seal. In particular, heat sealing was not possible if the container lid was too thick.
- This invention solves all of the above problems, and It is an object of the present invention to provide a container ultrasonic sealing method that can set a wide range of sealing conditions without adversely affecting a container, and that can efficiently perform sealing. That is what you do. Disclosure of the invention

- the ultrasonic sealing device 42 includes a sealing device main body 52 attached to a support body 51 and a sealing device. It comprises a round bar-shaped horn 54 projecting downward from the main body 52 and having a downwardly facing sealing surface 53 at the lower end.
- a vibrator (not shown) is built in the sealing device body 52. As shown by the arrow in FIG. 2, the vibrator causes the sealing action surface 53 of the horn 54 to exert ultrasonic rotational vibration in a rotational direction about its axis.
- a depression 61 is formed in the center of the sealing surface 53, and irregularities 62 are formed around the depression 61.
- irregularities 62 are formed around the depression 61.
- an intersection groove 71 extending in two directions is formed on the sealing surface 53, as shown in FIG.
- the parallel groove 72 extending in one direction on the sealing surface 53
- the radial groove 73 extending radially on the sealing surface 53 as shown in FIG. 5 is provided. By being formed, those provided are given.
- the sealing conditions include, for example, the amplitude and oscillation time of the ultrasonic wave, the pressure applied during sealing, and the holding time thereof, and these ranges can be set widely.
- the pressing means may be other than the spring force.
- a fluid pressure cylinder or the like may be provided on the horn side.
- the container shown in FIG. 6 includes a cup-shaped container body 81 and a dome-shaped lid 82.
- a flange 83 is provided in a lower part of the container body 81.
- a flange 84 is provided at the lower edge of the lid 82, and is overlapped with the container body flange 83.
