ー１側のヒートシール面２′の勾配と同一勾配にする。[Embodiment] FIG. 1 shows an embodiment of the present invention, in which a portion of the seal holder 5 corresponding to the heat seal surface 2'of the tray 1 has a clearance larger than the gradient of the heat seal surface 2'of the tray 1. A slope 5a is formed, while the heat surface 7a of the seal frame 7 is made the same as the heat seal surface 2'on the tray 1 side.
なお、シール受台５側の逃げ勾配5aの傾斜角度はトレー
１側のヒートシール面２′の傾斜角度よりも十分大きい
ことが条件で、ヒートシールの際にヒートシール面２′

ートシール面２′に確実にヒートシールされる。With the above configuration, the film 4 is interposed between the tray 1 and the seal frame 7 to seal the tray 1 with the sealing film 4, and the seal frame 7 is lowered when the seal frame 7 is lowered. The film 4 is pinched between the surface 7a and the heat-sealing surface 2'on the tray 1 side. And tray 1
Due to the elastic action of the heat-sealing surface 2 ', the uneven thickness error and deformation of the tray 1 are absorbed, and the film 4 is reliably heat-sealed to the heat-sealing surface 2'of the tray 1.
