A squeeze container (10) that includes a container body (13) including squeezable/deformable press-deforming portions (27), and that discharges a content contained in an inner bag (11) inside the outer container (13) by squeezing (pressing) the press-deforming portions (27). The outer container (13) has a tubular body portion (12) including: the press-deforming portions (27); and longitudinal-direction reinforcing portions (13e) molded integrally with the press-deforming portions (27). A pair of longitudinal-direction reinforcing portions (13e) is provided, the longitudinal-direction reinforcing portions extending in a longitudinal direction at respective two locations opposing one another in a radial direction of the tubular body portion (12). A pair of press-deforming portions (27) is provided, the press-deforming portions being arranged in respective sections between the pair of longitudinal-direction reinforcing portions (13e) so as to oppose one another, and each preferably having an arcuate cross-sectional shape so as to form the overall circular hollow cross-sectional shape of the outer container (13).

Provided is a double container which comprises a relatively rigid outer container and a flexible inner container disposed inside the outer container and capacity-variable in response to an amount of a content thereof The double container is configured to contain, particularly, a high-viscosity liquid, e.g., a liquid having a viscosity of 1000 to 100,000 mPa/s, and to be easily produced by a forming technique having no significant difference from conventional techniques, wherein the double container for a high-viscosity liquid is capable of containing the content without causing oxidation thereof, while maintaining the outer container in its original shape or dimensions, and discharging the content by squeezing the outer container, irrespective of a level of a remaining amount of the content.

A double-walled tube for dispensing product includes an inner wall, an outer wall positioned around the inner wall, and an opening defined by the inner wall. The inner wall and outer wall are flexible to dispense product held within the inner wall through the opening when the inner wall and outer wall are flexed.

A bioplastic collapsible dispensing tube may include a collapsible tube having walls that include a bioplastic material; a distal end of the tube that is sealed; a proximal end of the tube, opposite the distal end, that has an opening; a nozzle on the opening; and a closure for the nozzle; wherein, when the closure is opened and the tube is collapsed, flowable material inside the tube is urged out of the nozzle; and the bioplastic material includes a bio resin selected from the group consisting of PEF, PBF, PTF, GPE, GPET, PLA, PDLA, PLLA, PHA, and PHBH. A method may include forming a tube and filling the tube with flowable material from the distal end.

Airless tubular container (1) with an outer tube (1a) and an inner container (1b) both provided with respective skirts (2a, 2b). The inner container (1b) comprises an adapter (3b) to couple the inner container (1b) to the outer tube (1a). The skirt (2b) of the inner container (1b) is joined to the adapter (3b) and comprises a deployable portion (20) arranged under the adapter (3b). The deployable portion (20) enables the length of the skirt (2b) of the inner container (1b) to be adjusted with respect to the length of the skirt (2a) of the outer tube (1a), during the manufacture of the tubular container (1). Furthermore, the deployable portion (20) allows a relaxed collapsing of the inner container (1b) during use of the tubular container (1).
