摘要： PURPOSE:To readily close a bag in a short time and prevent the contents from dropping and also from being visible from the outside, by providing an adhesive face along the edge of the opening of a bag body and sticking a tape for a grip. CONSTITUTION:An adhesive face 3 is provided at the end edge or the edge of the opening 6 of a bag body 1 made of thermoplastic polymer films 1a, 1b and an extensible or non-extensible tape 2 is stuck to an adhesion face 3 and further, both ends of the tape 2 are superposed and welded with heat at both end edges 5 of the bag body 1. When the extensible or the non-extensible tape 2 is peeled off, the opening 6 of the bag 1 can be closed by the adhesive action of the adhesion face 3 and hence, the contents are prevented from dropping and the inside of the bag is not watched from the outside and hence privacy is protected. Since both ends of the tape 2 are put in both end edges 5 and welded with heat to have a strength, the tape can be used as a carrying grip 2.

摘要： A flexible container for filling, transport and storage of bulk material is made from at least one piece of base material. The bottom of the container is formed from at least four paired, preferably equally large, flaps which are direct extensions of the container side walls. The bottom flaps are formed by cut lines in the piece of material, and the angles alpha and beta of alternate flaps converge toward the center of the bottom. The sum of top angles alpha and beta of the flaps is less than 360 DEG , such that the container bottom formed by joints of the flaps is downward slightly cone or funnel shaped when the container is filled. The sum of the angles alpha and beta of the flaps preferably is between (240 DEG -280 DEG ) and 360 DEG . The container bottom will be substantially square or rectangular, depending on whether alpha = beta or alpha NOTEQUAL beta . Each of the bottom seams can terminate at a distance from the center of the bottom such that there are no seams in a minor area around the center, and in this area there can be arranged a discharge spout.

摘要： PURPOSE: To relieve support force to be transmitted by adhering or fusing a bottom part to or on a leaf, sealing/connecting the leaf in/to an inside end part of a corner tuck and side tucks, and constituting so that leg-shaped strips of a grip part are adhered to or fused on the side tucks. CONSTITUTION: In a workpiece of a sack, a corner tuck 5 and side tucks 6 and 7 are partially separated from the corner tuck 5 by an obtained notch line 2 by installation of a bottom part, and a rectangular leaf 12 is placed on a square body of a bottom part, and covers an inside part 13 of the corner tuck 5 and a part of the side tucks 6 and 7, and is adhered or fused as a whole, and the bottom part is sealed. Though sideways directional leg-shaped strips 16 and 17 joined to a grip part are placed on the bottom part, since the side tucks 6 and 7 are adhered by being folded up on the leg-shaped strips, a flat tunnel passage 25 is formed between the leg-shaped strips 16 and 17 and the leaf 12, and support force is preferably transmitted to both side walls of the sack.

摘要： PURPOSE:To improve appearance of a package bag and enable excellent joint strength by heat-sealing a sealant layer provided on a surface part with a sealant layer provided on a rear part via cut parts such as through holes or cuts provided on required positions of folded sides of each gusset. CONSTITUTION:A rectangular-shaped laminate film 1 has respective parts 2, 3, which are positioned between upper and lower peripheries and virtual lines and are to be subjected to top sealing and bottom sealing, on upper and lower end parts. Respective sealant layers on a surface part 18 and a rear part 19 are heat-fused strongly enough with each other on parts where they are in direct contact with each other and also on parts where the sealant layers are in contact through their respective through holes, and they are in contact with each other through punched holes 14, 15 provided on an inner part of a back seal part 20 and punched holes 16,17 provided on the rear part. The respective sealant layer parts on the back sealing outer part and surface part are heat- fused with each other with high strength.

摘要： PURPOSE: To discharge the content into a liquid medium without exposing the content to the environment or a worker by providing a container to store the substance to be added to the liquid medium comprising a part to be easily soluble and/or dispersible in the liquid medium, and a part not to be soluble and/or dispersible in the liquid medium. CONSTITUTION: In a container for dangerous goods such as the condensate of agricultural chemicals, a container 10 has surfaces 2, 4, 6, 8 having folding lines to be indicated by the dashed dot lines. End parts of the surfaces 2, 4 and end parts of the surfaces 6, 8 are folded along the folding lines 12, 14, 16, 18, 20, 22 and the folding lines 24, 26, respectively. The folded end parts fix a water-soluble or water-dispersible paper piece 28, and held at the regular position. The container is filled with, e.g. herbicide, and its tip is sealed. When in use, a bottom part of the container is immersed in a water tank, and then, lifted and a wet bottom part is detached from water. The paper piece 28 is soluble or dispersible, the content opens the bottom part with its weight, and falls into water to be soluble or dispersible.
