Patent

CA 2673948

In one embodiment of an apparatus and process for packaging foodstuffs or other materials in a rigid container sealed by a flexible cover, a desired quantity of material to be packaged containing or together with some water or other liquid is placed in the container, the flexible cover is secured on the container so as to leave at least one unsealed opening, the container is heated and/or placed in a partial vacuum to bring the liquid above its boiling point to cause or permit vapor generated by the boiling liquid to expel other gases from the container through the unsealed opening, and the container is sealed while gas or vapor is still flowing out of the container through the unsealed opening.

La présente invention concerne, dans un mode de réalisation, un appareil et procédé d'emballage de produits alimentaires ou autres matériaux dans un récipient rigide scellé par un couvercle flexible, dans lequel une quantité voulue de matériau à emballer contenant de l'eau ou autre liquide, ou conjointement à l'eau ou au liquide, est placée dans le récipient, le couvercle flexible est fixé sur le récipient de manière à laisser au moins une ouverture non scellée, le récipient est chauffé et/ou placé dans un vide partiel afin d'amener le liquide au-dessus de son point d'ébullition afin de faire en sorte ou de permettre que la vapeur générée par le liquide en ébullition expulse d'autres gaz à partir du récipient à travers l'ouverture non scellée, et le récipient est scellé tandis que le gaz ou la vapeur s'écoule encore à l'extérieur du récipient à travers l'ouverture non scellée.
