摘要： PROBLEM TO BE SOLVED: To provide a gable-top easily unsealable paper container capable of satisfying two conflicting functions of sealability and unsealability and fully opening a top. SOLUTION: A top seal of a gable-top paper container is formed, using a laminate consisting of an outer layer, an intermediate layer mainly comprising paper and an inner layer, by folding respectively a pair of opposite end panels connected with upper sides of side panels of a rectangular parallelepiped barrel consisting of the four side panels inwardly via slant creases, concurrently two-folding an inner rib panel connected with the upper side of the end panel via a center crease, then, in conjunction with the former step, falling another pair of opposite roof panels inwardly, falling an outer rib panel connected with the roof panels concurrently, and butt-seam-sealing the outer rib panel with two-folded inner rib panel interposed. The top is formed in the form of a gable top, thereby obtaining the gable-top paper container. An unsealing piece to be pinched between fingers to unseal the top seal for fully opening the top is provided on the upper side of the pair of opposite outer rib panels, thereby providing the easily unsealable paper container.

摘要： PURPOSE:To provide a convenient filtering paper cup for quickly separating solid and liquid. CONSTITUTION:A filtering paper cup 1 is composed of a cylindrical paper 2 coated with a thermal fusion resin on the inner surface thereof and a bottom material 3 made of nonfabric of thermal fusion resin. That is, an erected part 4 of the material 3 is heat-sealed on the lower inside of the paper 2 for bonding each other. Since the material 3 made of nonfabrics drops the liquid in the mixture of solid and liquid quickly, filtering can be made conveniently and quickly.

摘要： PROBLEM TO BE SOLVED: To stick a lebel easily on a body of a cup and perform the readout, etc., of bar codes easily by providing a plane part at a portion of at least one place on a conically trapezoidal curved-surface of the cup. SOLUTION: A deformed cardboard cup 10 has a plane part 4 provided at one portion only on a body surface thereof, and, at the plane part 4, a curled mouth edge 2 is processed in a linear state. By this method, a label 5 stuck on the plane part 4 can be seen without being distorted, and, even in the case of sticking a label on the body, the label can be easily stuck on a predetermined position as compared with the case of sticking it on a conically curved face. In the case where bar codes printed on the label 5 are read by a handy type bar code reader, the readout of the bar codes can be correctly and easily performed.

摘要： PROBLEM TO BE SOLVED: To provide a lid material which is capable of maintaining the shape retaining properties of a container by preventing paper separation or the water absorption of a flanged part from occurring at the time of opening the lid, in the lid material which hermetically seals a container made mainly of paper and still enables the sealed part to be easily opened. SOLUTION: This lid material 10 which is hermetically sealed with the flanged part 17 of a container 15, consists of a basic material 1, an easily separable layer 3 of polymery polymer alloy or a polymer blend, and a heat sealable layer 5 which can be thermally stuck to the flanged part 17 and easily cut.

摘要： PURPOSE:To obtain a stick which requires a small amount of material used and which is free from environmenral problem upon discarding after use. CONSTITUTION:A paper pipe 3 is passed through a hole 2a of a disk 2 made of pasteboard and the upper projecting part 3a and the lower bar part 3b are turned in different directions and both of them are made flat. In this way a stick is made which has its disk part securely held a the border between the projecting part 3a and the bar part 3b and which can perform its function. Since the stick is entirely made of paper, no environmental problem is caused upon discarding unlike the conventional resin-made stick. This stick also requires a small amount of material used, compared with the stick cut out of wood.

摘要： PURPOSE:To prevent the paper layer of a paper cup from breaking when the heat-sealed cover is peeled off and obtain an easily unsealing characteristic without loss of the sealing strength. CONSTITUTION:A plastic layer 5 with strength is laminated between a thermoplastic resin layer (polyethylene layer 6) at the contact side with a cover material 8 and a paper layer 3. The cover material 8 having an easy-peel-sealant 11 at the innermost layer is hermetically sealed with heat. When the cover is peeled off, the part between the thermoplastic resin layer (polyethylene layer 6) getting into contact with the cover material 8 and the innermost layer of the cover material 8 or the inside of the innermost layer of the cover material 8 is broken and the paper layer 3 of the paper cup 1 side is opened without breakage.
