In conventional compression sacks having an access port for articles and an air outlet formed in a part thereof, according to the air stream produced during deaeration, some of the contents may be caught in the air outlet by the force of the air stream. In a compression sack including an air outlet coated with adhesive matter, the foregoing action may cause a risk of articles contained in the sack being damaged by touching the adhesive matter according to the position of the articles. In this connection, by providing a point seal in the end at the interior's side of the deaeration passage, articles, such as clothing, contained within the compression sack can be prevented from being caught in the deaeration passage during the deaeration. The provision of an auxiliary deaeration passage in the separating member may allow a quick removal of air present in a space inside the access port of the sack, thus securing smooth deaeration. The provision of shut-off seals or a liquid sealing portion in the deaeration passage may prevent air from returning to the inside of the compression sack.
