Abstract:
A container body (11) is provided with a squeeze operating portion (13a) between a shoulder portion (15) and a bottom portion (14), the squeeze operating portion including a squeeze face portion (16) opposed to a squeeze direction X, a pair of lateral support wall portions (17) arranged along the squeeze direction X at both side sections of the squeeze face portion (16), and inclined linking face portions (18) arranged as being inclined therebetween. When the squeeze face portion (16) is compressed to the squeeze direction x, the inclined linking face portions (18) expand distance between the pair of lateral support wall portions (17) at both sides as deforming along the squeeze face portion (16) from an inclined state against the squeeze face portion (16). The inclined linking face portions (18) are restricted so as not to be flipped in the squeeze direction (x) side after deformation completes as expansion force vanishes, so that constant quantity of content liquid is discharged.
Abstract:
A method of manufacturing a self-supportable bag (10), comprising the steps of molding a synthetic resin bag body (11) in a mold, folding the molded bag body (11), and sealing the opening (12A) of the folded bag body (11).
Abstract:
A self-supporting bag comprises a bag main body (11) having a body portion (20) and a bottom portion (30) being blow molded or injection molded; wherein the body portion (20) has a filling port forming portion (22) and a pouring port forming portion (24); wherein the main body (11) comprises ridge line portions (41 to 47) for flattening; and wherein the bag main body (11) is comprised of synthetic resin.
Abstract:
A cap (10) for a squeeze container, used while being mounted to a mouth neck section (12a) of a container body (12), which is deformable by squeezing and consists of a plastic, and discharging the content liquid from a discharge opening (13) at the front end of the cap by the deformation by squeezing of the barrel section (12b) of the container body (12). At least a part of the liquid flow path from the mouth neck section (12a) of the container body (12) to the discharge opening (13) is a helical flow path (15). The helical flow path (15) is provided so that the bottom surface section (15a) thereof declines toward the barrel section (12b) of the container body (12) when the squeeze container (11) is in an erected position. The helical flow path (15) is formed, for example, by a helical tube (14) disposed inside the cap (10) for the squeeze container.
Abstract:
A container of the present invention has a valve (2) and a lid (3) which covers the valve (2) from the outside. The valve (3) is provided a slit (23) which opens due to outward deformation of the valve (3) when the internal pressure of the body (1) is higher than atmospheric pressure, and which closes up due to elasticity of the valve (3) when the internal pressure is approximately equal to atmospheric pressure. The container of the present invention further comprises a pushing structure (4) formed on the inside of the lid (3), this pushing structure (4) being shaped so as to come into contact with the valve (2) when the lid (3) is shut, thereby pushing the valve (2) slightly inwards to open the slit (23).
Abstract:
Disclosed is a fixed-amount discharge squeeze container (10) which is provided with a container main body (11) configured from a plastic that can be squeezed and deformed, and which discharges a predetermined amount of contained liquid from a discharge outlet by squeezing and deforming the container main body (11), wherein the body section (13) of the container main body (11) is provided with a squeeze operation section (14) for performing squeeze operation. The squeeze operation section (14) has a cross-sectional shape formed from a squeeze surface section (16) which has an outward-protruding angular cross-sectional surface provided with a pair of slanted sections (15) arranged along two surfaces which intersect at an obtuse angle, and a squeeze support section (18) which has an arc-shaped cross-sectional surface, and which is integrally joined with the hem section (19b) of the squeeze surface section (16) via a ridge section (17). The squeeze surface section (16) is regulated so as to not invert into an inward-protruding angular shape after the slanted sections (15) had deformed to the point where there is no longer any force to expand the space between the hem sections (19b) on both sides.
