<p>A container comprises an outer container body and an inner container body. The outer container body has flexibility owing to which the container is deformable by squeezing and restorable to its original form, and comprises a hollow cylinder-shaped outer container body mouth that is stood on the upper part of the container. The inner container body that is deformable and reducable in volume is located inside the outer container body with a hollow cylinder-shaped inner container body mouth fitted and fixed directly to the outer container body mouth. A check valve mechanism is constituted of a first check valve portion and a second check valve portion. The first check valve portion is fitted and fixed inside the inner container body mouth, and opens and closes an opening portion of the inner container body mouth while blocking the entry of outside air. The second check valve portion is fitted and fixed to one of the outer container body mouth and the inner container body mouth, and the end portion of the second valve portion is in circumferentially close contact with the other. The second valve portion opens and closes a passage, formed between the outer container body and the inner container body and extending from the top ends of the mouths to the bottoms, such that air entry from the outside is possible and air exhaust from the inside is impossible. The check valve mechanism can be realized with high productivity in a small-sized, double-walled container. Thus, a dispensing container is produced at high productivity, allows no entry of outside air to the inside and is excellent hygienically.</p> |
