摘要:
A process for producing biaxially drawn plastic bottles having excellent heat resistance and an apparatus therefor. The process comprises a step of biaxially drawing and free blow-molding the preformed article to obtain a secondary molded article thereof, a step of heating the secondary molded article by inserting it for 0.3 to 5 seconds in the infrared rays emitted from an infrared-ray radiation member that has a substantially planar radiation surface having a height larger than that of the secondary molded article in the direction of height and having a surface temperature of from 350.degree. C. to 1000.degree. C., in order to obtain a tertiary product thereof that is shrunk, and a step for blow-molding the tertiary product that is in a heated state in a metal mold to obtain a final molded article. A single metal mold is used for blow-molding to shorten the time occupied by the metal mold and to produce the bottles having excellent heat resistance maintaining high productivity.
摘要:
A container is obtained by biaxially stretch-blow-molding a resin. Except the mouth-and-neck portion, vicinities thereof and the center of the bottom portion, the container as a whole is reduced in thickness under a highly drawing condition without being accompanied by whitening, and a portion constituting the bottom valley portions has an yielding load of not smaller than 25 kg/cm at 70.degree. C. The container exhibits excellent heat resistance, pressure resistance, shock resistance as well as self-standing ability.
摘要:
In a biaxially-stretch-blow-molded container there is a method of producing the same. Redraw ratio at the bottom portion is small in the secondary blow molding without employing a complex heating system but in which a secondary article obtained by subjecting a preform article to the primary blow molding is preferentially shrunk at its bottom portion, and a tertiary article or a quaternally article before being subjected to the secondary blow molding is obtained having a bottom of a flat shape or in which the central portion is recessed inwardly of the container and the periphery thereof is flattened. The bottle obtained by this method has a thickness and crystallinity in the bottom portion which are nearly the same as those of the center of the barrel and are highly oriented. The heat-resistant bottle exhibits excellent strength in the bottom portion and symmetrical panel-sinking stability in the vacuum pressure.

The absorbent article of the present invention comprises: a liquid-pervious surface sheet, a liquid-impervious backside sheet provided at the position opposing said surface sheet, and an absorption body provided between said surface sheet and said backside sheet, wherein the absorbent article comprises an endless compressed groove, surrounding a central part of said absorbent article, which is formed in said surface sheet and said absorption body in the thickness direction, and a plurality of concave parts, provided inside and outside said compressed groove, which are formed in said surface sheet and said absorption body in the thickness direction, and an uncompressed region bordering inner and outer edges of the compressed groove, wherein the closest distance between said compressed groove and the nearest concave parts is greater than the distance between adjacent ones of those same concave parts.

A plurality of convex portions that protrude radially outward from a plurality of positions separated in the circumferential direction are provided on the outer peripheral surface of a driven gear. Each convex portion has, in the circumferential direction of the driven gear, a rising surface that rises from a minimum diameter position to a maximum diameter position in the direction opposite the rotational direction of the driven gear, and a falling surface that falls from that maximum diameter position to a minimum diameter position that is adjacent to and in back of that maximum diameter position with respect to the rotational direction of the driven gear. The circumferential length of the falling surface is greater than the circumferential length of the rising surface.

An absorbent article package is individually packaged by folding a packaging sheet and an absorbent article in a state where the absorbent article is arranged on the packaging sheet. In a state where the individually-packaged absorbent article is opened, in the packaging sheet and the absorbent article, a first folding line based on which the absorbent article and the packaging sheet are folded towards the topsheet side, and a second folding line based on which the absorbent article and the packaging sheet are folded towards the backsheet side are formed adjacent to each other in the longitudinal direction.
摘要:
According to the present invention, an HCV replicon-replicating cell is produced by a production method including a step of introducing RNA containing an HCV replicon sequence and a selectable marker gene sequence into a Li23 cell or a cured cell derived from a Li23 cell. Further, a full-length HCV RNA-replicating cell is produced by a production method including a step of introducing RNA containing a full-length HCV genome sequence and a selectable marker gene sequence into a Li23 cell or a cured cell derived from a Li23 cell. The use of these cells enables the construction of an HCV life cycle reproduction system that is derived from a cell line other than the HuH-7 cell line and that has capabilities equivalent to those of an HCV life cycle reproduction system derived from the HuH-7 cell line.
