摘要:
A container composed of a plurality of container materials the opposing parts of which are sealed by heat sealing, wherein at least an opening start part of the sealed portion is of a laminated structure consisting of the plurality of container materials and an intermediate material inserted therebetween. The intermediate material and one of the container materials are tightly sealed, and the intermediate material and another of the container materials are sealed easily peelably. The inside end edge of the easily peelable seal portion is positioned more toward the center of the container than the inside end edge of the tight seal portion. At an opening start position, the outside end edge of the easily peelable seal portion is positioned more toward the center of the container than the outside end edge of the tight seal portion, and the intermediate material is provided so as to jut outwwardly of a heat sealing flat portion of a container flange. The strength of peeling of this sealed container from its central side is high enough to withstand retorting or the like, and opening of the container from outside can be effected by hand accurately and stably.

The present invention relates to an easy-open vessel lid which is composed of a laminate of a metal foil and a resin and has opening weakened line. A reinforcing layer of a thermoplastic resin is formed independently from the resin of the laminate at least on the outer peripheral side of a part most protruding in the opening-initiating direction of an inside introducing weakened line to cover said weakened line astride of said weakened line. By this reinforcing layer, ribbon breaking can be effectively prevented, and opening by shearing of the lid member along the weakened lines can be performed assuredly and smoothly.

A laminate for flexible packaging and a process for preparing the same. The laminate for flexible packaging is obtained by joining a plurality of flexible blanks via layers of an adhesive agent, wherein the layers of said adhesive agent are layers of an isocyanate-terminated polyurethane type hot-melt resin that is crosslinked with the moisture, the residual amount of an organic solvent in said laminate is 10 .mu.g/m.sup.2 or smaller per a unit inner surface, the peeling strength at 25.degree. C. is 250 g/15 mm of width or greater, and a peeling strength retentivity at 80.degree. C. is 30% or greater of the peeling strength at 25.degree. C.

摘要:
A plastic container made of olefin resins having frosted appearance which gives excellent shade-off, deep and high-grade impression, and a process for producing the same. The process produces a plastic container having the above-mentioned appearance maintaining good reproducibility and excellent moldability. That is, a frosted plastic container wherein at least the outer surface of the plastic container is formed of a blend of plural kinds of olefin resins, one resin (A) forming the layer of said blend exists as a continuous phase, another resin (B) exists as a disperse phase, and the disperse phase which has an aspect ratio (ratio of long diameter/short diameter) of 6 or smaller and in which the grains exist having grain sizes (short diameters) of from 0.3 to 20 .mu.m, has an area percentage of at least 15% or larger relative to the whole sectional area.

A magnetic tape cartridge is provided, in which the mating of the lower half and the upper half can be easily performed and which is applicable to automated assembly, when the magnetic tape cartridge having a sliding door is assembled. The rib projects from the upper section of the first guide wall in the direction of the opposite second guide wall. On the other hand, the groove, which faces the rib, is carved on the inner side surface of the sliding door. The rib engages with the groove, thereby restricting the vertical displacement of the sliding door. Also, the engagement of the rib and the groove guides the sliding door in the guide channel freely.

摘要:
Disclosed is a method for welding tape cartridge reels, with ensuring a high level of parallelism between both their flange portions. Specifically, this method for welding a tape cartridge reel, the tape cartridge reel including a flange having a welding rib and a flange-integrated reel hub, the method includes: pressing the flange against the flange-integrated reel hub by using an ultrasonic horn, while vibrating the flange by means of an ultrasonic wave from the ultrasonic horn, so that the flange is welded to the flange-integrated reel hub through the welding rib; and terminating a welding operation of the ultrasonic horn, while the flange is in contact with the flange-integrated reel hub only through the welding rib.
