Abstract

PROBLEM TO BE SOLVED: To smoothly draw out relatively viscous liquid food without forming a large opening in a container body, by forming circumferential steps at the peripheral face of the container body and squashing the body so as to collapse the steps and making the height of the body compressible. SOLUTION: A plurality of steps 11 are nearly concentrically formed in the circumferential direction at the peripheral face of a container body 1. On unsealing the container body, a projection 13 is pulled up together with a cover member 2 integrally heat-sealed and after the cover member 2 has been peeled off by a required volume, the container body is squashed so as to collapse the steps 11 and compressed to obtain a nearly even height thereof. In this way, the liquid food can be smoothly and completely drawn even when the unsealed opening area is small, by drawing the relatively viscous liquid food contained in the container 1a so as to squeeze it.
