摘要： PROBLEM TO BE SOLVED: To provide a carton wherein a content is prevented from leaking out from a cutting line, in the carton for which the cutting line such as a perforation or a zipper is applied for unsealing. SOLUTION: For this carton, the cutting line P such as a perforation or a zipper is applied at one section. In such a carton, a content leakage-preventing means is applied at a region including the cutting line on the rear surface or the front surface of the carton. As the content leakage-preventing means X, a coating agent is coated, or a film is pasted.

摘要： PROBLEM TO BE SOLVED: To improve the performance and productivity without any special curing device by forming a wrap film holding part to prevent a cut wrap film end from being re-wound in a carton of a coated layer of a rein excellent in adhesivity even to the wrap film poor in self-adhesiveness. SOLUTION: A resin mainly consisting of silicon modified acrylic resin is coated on a part lapped on at least a covering piece 15 of a front plate 11 of a carton A in which a roll-like wrap film F is stored, to form a wrap film holing part P. The silicon modified acrylic resin requires no special curing device for the bridging reaction, and is capable of easily forming a coating film layer through the application of the resin to a regular gravure printing machine, etc. The coating film layer is excellent in self-adhesivity even to the wrap film poor in self-adhesiveness such as polyethylene, polypropylene, polymethylpentene and polypropylene, and the cut wrap film end is effectively prevented from being re-wound in the carton A.

摘要： PROBLEM TO BE SOLVED: To provide a film retaining member with a stable retaining property to a wrapping film by a method wherein the wrapping film retaining member, that prevents the free end of the wrapping film from winding back when the rapping film is cut off, includes an adhesive layer of specific resin composition that has a good adhesion to the wrapping film and is excellent in both film retaining and independent-of-temperature properties. SOLUTION: An adhesive layer 22 to retain a wrapping film is provided on the surface of a front panel 2 of a carton and when the wrapping film is cut off, the wrapping film is adhered on the adhesive layer 22 by pressing the wrapping film onto the surface of the front panel 2 from outside a side flap 6 of the carton. The adhesive layer 22 is formed of a hardened material of a composition containing a setting adhesive component comprising polyurethane type pre-polymer and an adhesive control component comprising non-reactive acrylic resin. Polyurethane type pre-polymer that composes the setting adhesive component comprises a moisture-setting type polyurethane resin, and it is desirable that the pre-polymers are chosen from such sorts of pre-polymers that polyol in their components has a molecular weight within a range of 1,000-3,000 and elongation percentage within a range of 20-160%.

摘要： PROBLEM TO BE SOLVED: To numerically express the cutting strength of a wrapping film as an objective evaluation criteria, by pulling out wrapping film out of a wapping film carton fixed in a rotary part and fixing to a measuring part with a fastening tool and rotating the wrapping film to the peripheral direction. SOLUTION: A corton 8 for wapping film is inserted in a holder 1 and fixed by a stopper 2. Then the wapping film 9 is pulled out of the carton 8 and the end thereof is held by a fastening tool 4 and fixed thereto. Then the wrapping film 9 is pulled by a tension-adjusting handle 6 of the wrapping film to decide an initial position. After the adjustment, a starting button 7 for measurement is pushed on. Then a rotary actuator 3 and also the holder 1 start to rotate and the wrapping film 9 is cut by a V-shaped cutter blade fitted to the carton 8 for the wrapping film 9. The maximum tensile force at that time is measured by a gauge 5.

摘要： PURPOSE: To surely bond a slender serrate cutter to a carton blank. CONSTITUTION: An adhesive 6 is applied to a carton blank 1 so as to bond a non-metallic and weldable serrate cutter 2 over the whole length of the applied adhesive. After that, both the ends of the serrate cutter 2 are ultrasonically sealed with a ultrasonic horn 20. Thus, both the ends of the serrate cutter 2, which is conventionally liable to be unstably bonded with adhesive 6, can be surely bonded, resulting in preventing serrate cutter 2 from peeling off during use.

摘要： PURPOSE:To make handling easy, yet with excellent heat-insulating effect maintained, and furthermore to prevent contents from being soaked in surplus water or oil. CONSTITUTION:A carton is made up in a structure, in which side sheets 5-8 are provided on four sides of a rectangular bottom sheet, and a cover sheet 13 is provided on the upper edge of one side sheet 8. A receiving sheet 16 in the size approximately the same as the bottom sheet is provided in connection with the upper side of one of the remaining side sheets through a connecting sheet 15 in the width smaller than the height of the side sheet. The receiving sheet 16 is inserted into the carton, and a space is formed between the receiving sheet and the bottom sheet. As occasion demands, holes 16a are provided to the receiving sheet 16. Heat insulating effect functions by virtue of the space provided between the bottom sheet and the receiving sheet. Providing a tray separately becomes unnecessary while throwing-away becomes easy. Since water or oil coming out of the contents drip through the holes 16a, the contents can be protected from deterioration that arises from soakage in the water or the oil.

摘要： PROBLEM TO BE SOLVED: To provide a heat-insulating label and a container with the heat- insulating label stuck thereto having heat-insulating properties and capable of forming a heat-insulating portion on the container by sticking it only to a necessary portion of the container so that the container containing contents having a high temperature is held with fingers. SOLUTION: This heat-insulating label A is formed by punching a heat- insulating label member 10 into a predetermined shape. The label member 10 comprises a corrugated paper layer 11, a liner paper layer 12 and a pressure- sensitive adhesive layer 14, wherein each of the layers is successively laminated on one another from at least an outer face side in the order named. A container with a heat-insulating label stuck thereto is a container having this heat- insulating label A stuck to a part thereof and, particularly in this case, a paper cup, a plastic cup or a can is to be used for the container.

摘要： PROBLEM TO BE SOLVED: To obtain a storage box with a small amount of a paper base to be used for a blank wherein manufacture is easy, and the box is excellent in durability at a cutter part and in appearance and handlability by sticking a cover piece to a storage box body for integration. SOLUTION: A cover piece is stuck across an upper lid 15 and a cut board 16 of a storage box body. Thus a cutter part 17 is prevented from being exposed outside, while the cut board 16 is integral with a reinforcing board 23 of the cover piece so that it is reinforced. When the storage box is to be unsealed for use, first, an end of a protection board 22 is held, and the protection board 22 is removed by pulling it along a cut line A. As a result, the upper lid 15 can rotate with a crease (c) as the center to allow an opening to be opened/ closed. In addition, the cut board 16 is integral with a reinforcing board 23 so that it can be in contact with/separate from a front board 13 according to a rotation of the upper lid 15. A long object is pulled out from a roll R by a predetermined length and brought into contact with the cutter part 17, and the long object is pulled upward thereby cutting the object.

摘要： PROBLEM TO BE SOLVED: To enable removing of a metal serrate blade from a used carton easily and safely so that the body of the carton and the serrate blade can be put in a separated state at disposing them. SOLUTION: In a carton for storing a packaging web, a web wound in a roll is stored and a metal serrate blade 14 for cutting off the web to a required length is provided. A cut tape is stuck side by side with the serrate blade 14 and at least on one side of the cut tape a pulling-initiating part 17 for pulling the cut tape is formed. To separate the serrate blade 14 all there is to it is to pull the cut tape. Since it does not occur for the hand to directly hold the metal serrate blade 14 or, in separating it, to injure the hand by change of its shape, the serrate blade 14 can be separated easily and safely.
