A pressurized fluid that is introduced from a passage 4 into a space between an outer bottle body 24 and an inner container body 31 causes the inner container body 31 to be deformed and be reduced in volume so as to form a space between the inner container body 31 and the outer bottle body 24. When doing so, a stopper rod 82 is inserted into the interior of the inner container body 31 through an inner mouth portion 30 before the deformation of the inner container body 31 starts so as to cause the stopper rod 82 to come into contact with and become fixed to the bottom portion of the inner container body 31.

The inner peripheral surface of the inner opening part 17 has a small-diameter part 24 having a diameter smaller than the internal diameter of the open end of the inner opening part 17.
Provided is a synthetic resin multilayer bottle in which it is possible to reliably prevent contents that comprise a liquid seasoning, including soy sauce, from degenerating due to oxygen, etc., in the outer air. The synthetic resin multilayer bottle 1 comprises an outer shell bottle 2 that is capable of returning to an original shape in response to deformation by pressure, an inner container body 3 that deforms due to pressure, and an air channel 23 that guides outer air between the outer shell bottle 2 and the inner container body 3. The synthetic resin multilayer bottle 1 comprises oxygen permeability properties such that, after the inner container body 3 has been completely filled with distilled water from which dissolved oxygen was removed, an inner opening 17 has been sealed, and the distilled water has been allowed to stand for 60 days at a temperature of 20°C while the air channel between the outer shell bottle and the inner container body was in an open state, the amount of dissolved oxygen in the distilled water is 3 ppm or less.
A synthetic resin multilayer bottle includes an outer shell bottle and an inner container. The outer shell bottle is capable of restoring itself to its original shape against external pressure. The shoulder portion has a polygonal pyramidal shape, and the bottom portion has a polygonal pyramidal shape, including ridge lines continuing to the extended lines of the polygonal pyramidal ridge lines of the shoulder portion. The inner container includes a an inner container body having a shape extending along the internal shape of the outer shell bottle. It further includes an air passage formed between the outer mouth portion and the inner mouth portion.

Provided is a discharge container in which an inner container deforms according to a reduction in the contents, and which can be reused and has an excellent aroma retaining property. In order to achieve this, this discharge container (10) is provided with: a container body (13) having a flexible inner container in which contents are filled and which contracts and deforms according to a reduction in the contents, and an outer container which houses the inner container and has an air intake hole for suctioning external air, the intake hole being formed between the outer container and the inner container; a discharge cap (15) having a discharge port which is for discharging the contents, and is formed on the top surface part of the discharge cap and attached to a mouth part (13a) of the container body (13); and an external air introducing hole that communicates the outside and the air intake hole, wherein the inner container and the outer container are composed of a polyethylene terephthalate resin.
Provided is a synthetic resin multilayer bottle that is easy to manufacture and with which it is possible to reduce the amount of contents remaining as a residue.

A method and a device capable of producing a high quality, sanitary content filling bottle efficiently in the production of such a content filling bottle that deformation of the body section due to reduction in pressure is prevented by inverting protrusion and recess at the bottom. An empty bottle (1) is filled with content under a state where an inverting portion (11) is projecting to the outside of the body section, and, after the bottle (1) is sealed by fitting a cap (6) to the mouth portion thereof, an auxiliary tool (27) is attached to the bottom (5) of the bottle (1). Bottom of the bottle (1) to which the auxiliary tool (27) is attached is then supported through the auxiliary tool (27), and the inverting portion (11) projecting downward is pressed upward and inserted into the bottle (1) while being inversed. Subsequently, the mouth of the bottle (1) is grasped and the auxiliary tool (27) is separated from the bottle (1).
A method and device for manufacturing a content-filled bottle having an inversion part at its bottom. In producing the bottle, the inversion part is inverted to prevent deformation of a body part caused by a pressure reduction in the bottle, and as a result, inappropriate deformation and buckling of the bottle are prevented, enabling efficient manufacturing of the bottle with high quality. The bottle (3) is held from the outside by an empty-bottle chuck (41) of auxiliary device mounting means in such a way that the bottle (3) is held at its a mouth part (4) by the chuck along the upper surface of a flange part (10) of the bottle (3). Next, an empty-bottle support table (42) on which an assistance device (24) is placed is raised, the assistance device (24) is mounted on a bottom part (7) of the bottle (3), and the bottle (3) is placed on the empty-bottle support table (42). After that, with the empty bottle (3) held positioned by the empty-bottle chuck (41) and the empty-bottle support table (42), the inversion part (12) is projected to the outside of the body part (6) by a push-down member (54) of bottom projecting means. Then, the bottle (3) is filled with contents and sealed by a cap. The inverted part (12) is recessed into the body part (6), and the assistance device (24) is separated from the bottle (3).
