A foam dispensing container includes: a cap mounted on an opening of a container containing a foamable liquid content; a nozzle having an outlet fitted onto the cap while being allowed to reciprocate; an air pump and a liquid pump reciprocated together with the nozzle; an air cylinder joined to the air pump liquid and pushing air toward the outlet in response to reciprocation of the air pump; a liquid cylinder joined to the liquid pump liquid tightly and pushing a liquid toward the outlet in response to reciprocation of the liquid pump; and a refining member arranged in the cap to form the foam by mixing the air pushed out of the air cylinder with the liquid pushed out of the liquid cylinder, and to refine the foam. A density of the foam dispensed from the discharging outlet falls within a range of 0.03 g/cmto 0.06 g/cm.

Foam dispensing container

To prevent a reduction in a bending strength and a buckling strength of a container bag for fluid in which a spout is mounted on an upper end of a trunk section formed of a sheet material. Cellsare formed between two films of the sheet materialby bonding the films together along bonding lines, and inflated with fluid. The cellspositioned within a width of the spout in a width direction of the trunk sectionextends downwardly from a site at which the spoutis clamped by the layers of the sheet material. A lower end of the spoutis situated lower than upper ends of the cells

Container bag for liquid having a spout

To provide a container bagthat can be manufactured easily by folding a sheet materialprecisely along a folding lineB. The sheet materialis prepared by bonding two filmsandtogether in a predetermined pattern, and the sheet materialcomprises a plurality of cellsformed between the two filmsandwhile being joined to one another to be filled with fluid. A trunk portionto be filled with a content is formed by bonding overlapping layers of a peripheral edgeA of the folded sheet material. A bottom portionof the container bagis folded inwardly toward the trunk portionalong the folding lineB. A non-bonded sectionin which the two filmsandare not bonded together is maintained linearly within the folding lineB.
