2A, 2B and 2C, the container holding assembly 20 is used to set the container 1 at various positions on the base plate 10 in order to measure the adhesion strength of the sealing film 3 in various directions can do. Specifically, the container holding assembly 20 can be moved along the fixing bar 13 of the base plate 10 to set the position in the x direction, and the container rotating jig 23 can be rotated to be rotated in the xy plane And the height in the z-direction can be set by operating the height-adjusting lift 25.

Hereinafter, the detailed structure of the container holding assembly 20 and the process of setting the position of the container 1 will be described. First, in a state that the container 1 is mounted on the container fixing jig 21, the container 1 is fixed using the container fixing bolt B1 so as not to be shaken. The container (1) and the container holding jig (21) are fixedly coupled to each other and moved together.

The container rotation jig 23 is divided into a first container rotation jig 23a that rotates about the container rotation axis 24 and a second container rotation jig 23b that supports the first container rotation jig 23a . The first container rotating jig 23a may be formed integrally with the container holding jig 21 and may be provided on both side portions of the first container rotating jig 23a and the second container rotating jig 23b A pair of rotation guide lines 23c can be formed. Thereby, the first container rotating jig 23a can rotate around the container rotating shaft 24 on the second container rotating jig 23b by a predetermined radius.

For example, the angle can be adjusted by using the angle adjusting bolt 48 that moves the push-pull gauge assembly 40 in units of 1 degree, and the angle adjusting bolt 48 can be tightened, The end of the push-pull gauge assembly 40 can be fixed by a mechanical structure such as a latching jaw.

When the push-pull gauge assembly 40 is tilted at a certain angle, the push-pull gauge 41 may be rotated on the rotary plate 45 so that the film-securing clamp 43 faces the container 1. [ Further, the position of the container holding assembly 20 can be varied in various ways depending on the angle of the push-pull gauge assembly 40. For example, when the push-pull gauge assembly 40 is inclined at an angle of 45 degrees, the container holding assembly 20 must operate the height adjusting lift 25 to elevate the height of the container 1 in the z direction. The movable angle on the angle regulating plate 30 can be freely set in the range of 0 to 45 degrees. Further, the angle regulating plate 30 may be replaced or modified to set the angle range differently, for example, at an angle of 45 degrees or more.
