Abstract:
Disclosed is a paper cup which exhibits an appropriate barrier performance without deteriorating properties of a content therein. In the bonded portion of a side wall of this paper cup, one end portion of a side wall paper sheet located inner side of the cup has such a structure wherein the end face of a paper base layer is covered with a barrier layer while preventing both end faces of the paper base layer and barrier layer from being exposed to the outside. An end portion (3) of a side wall paper sheet (2) which is at the inner side of a side wall bonded portion (4) of a paper cup has a paper base-absent portion (18) which extends from a circular bottom (10) to an upper rim (12). In the paper base-absent portion (18), a paper base layer-removed portion (19) wherein the paper base is die-cut is covered with a barrier layer (15), and a barrier layer-removed portion (20) which is located inner side of the paper base layer-removed portion (19) and wherein the barrier layer (15) is die-cut is covered with a thermoplastic resin layer (14). The end face of the end portion (3) wherein the paper base-absent portion (18) is located is so formed that a paper base layer (16) and the barrier layer (15) are not exposed to the outside, and the end face of the paper base layer-removed portion (19) in the paper base-absent portion (18) is covered with the barrier layer (15).
Abstract:
A laminated wrapping material comprising a base material, a silicon oxide layer, an adhesive layer or an anchor-coat layer, and a heat sealing resin layer that are laminated in that order, wherein said adhesive layer or anchor-coat layer are formed by applying an aqueous adhesive composition or aqueous anchor coating agent composition onto said silicon oxide layer and then drying the same. A solvent-free type adhesive layer may be provided on said anchor-coat layer. A laminated wrapping material comprising a base material, a silicon oxide layer, an ink layer, an adhesive layer and a heat sealing resin layer that are laminated in that order, wherein said ink layer is formed by applying an aqueous ink composition onto said silicon oxide layer and then drying the same. In this case, it is preferable that the adhesive layer is formed by applying an aqueous adhesive composition onto the ink layer and then drying the same. In addition, in a case where a substance having oiliness is used as an ink composition, it is preferable that the anchor-coat layer is formed by applying an aqueous anchor coating agent composition onto the silicon oxide layer.
Abstract:
A dispenser adapted to accommodate therein an edible viscous material such as mayonnaise and cream and discharge the same in a predetermined amount. A bottomed cylindrical inner case (30), designed to such a lengthwise dimension that a shoulder portion of a cartridge (26) on an opening portion side is exposed from the opening portion in one end thereof and having a hole (31) through which a rod (22) is caused to pass in a bottom portion at the other end, is accommodated in an accommodation portion (2) for accommodating therein a viscous material. The cartridge (26) and an extruding plate (21) are accommodated in this cylindrical inner case (30), and the movement of the extruding plate (21) is made smooth. A gear body (10) provided coaxially with a supporting shaft for a trigger (4) is brought into mesh engagement with a pawl member (8) provided on the trigger (4) and a stopper (15) provided on the main body portion (1) of the dispenser. A rod (22) reciprocating inside the accommodation portion (2) is brought into mesh engagement with the gear body (10). A guide (19) sliding on the pawl member (8) is provided on the side of the main body (1) so that the pawl member (8) is disengaged from the gear body (10) when the trigger (4) is returned.
Abstract:
A process for synthesizing cyclodextrin polymer either by the reaction of cyclodextrin derivative with polyvinyl alcohol, cellulose or their derivative(s), or by the copolymerization of cyclodextrin derivative with vinyl acetate or methyl methacrylate; and a process for producing cyclodextrin film from the cyclodextrin polymer. The polymer has a high cyclodextrin content, and the film produced from this polymer can be used in the form of a single film without the necessity for using other supporting film, because the polymer itself has a capability of forming film.
Abstract:
A system for forming a thin film on a substrate uses a plasma to activate at least one gaseous precursor in a plasma generator fluidly coupled with a reaction space. The plasma generator is operative to generate a plasma from at least a portion of the precursor gas with at least one pair of plasma electrodes, one plasma electrode having a non-native electrically conductive adlayer exhibiting property characteristics that cause the adlayer to be substantially conserved and chemically active with at least one of the gases present within the plasma generation region.
Abstract:
A multi-layered film material having a structure wherein a protective layer, a composite film comprising a polyvinyl alcohol film or a film of an ethylene/vinyl acetate copolymer saponificate and a silicon oxide deposition layer formed on the former, and a heat-sealable polyolefin layer are laminated. In this case, each of the layers is transparent and the silicon oxide layer is disposed on the side of the protective layer. The protective layer and the composite film, and the composite film and the heat-sealable polyolefin layer are laminated by an adhesive layer, respectively.
Abstract:
A cyclodextrin polymer comprising cyclodextrin contained in the main chain of a polymer selected among polyurethane, polyurea, unsaturated polyester, polyester, polycarbonate, polyamide and polysulfone; and a cyclodextrin film formed from the polymer. The polymer contains an increased amount of cyclodextrin units fixed, has a remarkably improved functionality, and can be decomposed by enzymes, though being isoluble in water and other solvents because of the use of specified polymers, thus being usable as a degradable polymer. The film contains a large amount of cyclodextrin introduced thereinto and is usable as a single film.
Abstract:
Microwave-heated cooked foods filled in a see-through package in which the contents can be stored for a long time at ordinary temperature, particularly in a package made of a transparent wrapping material having high oxygen and water vapor barrier properties and a high microwave permeability. The wrapping material comprises a heat-resistant synthetic resin film or laminate, a heat-sealable heat-resistant synthetic resin film or laminate as an innermost layer, and an intermediate layer of a single metal oxide, particularly a thin film of silicon oxide or mixture thereof. After filling the package with the contents, it is irradiated with microwave to heat and sterilize, thus giving cooked foods having a long shelf life.
Abstract:
A system (100) for depositing a thin film on a flexible substrate (102) comprises a plurality of processing zones (104, 106, 108) spaced apart by an isolation zone (110), a plasma generator (130) for generating a plasma region (132) proximal to a pathway along which the substrate travels, and a substrate transport mechanism (128) for guiding the substrate back and forth between the processing zones so that the substrate is transported past and exposed to the plasma region when the system is in use.
Abstract:
A method (600) of forming a thin barrier film (200) of a mixed metal-silicon- oxide is disclosed. For example, a method of forming an aluminum-silicon-oxide mixture having a refractive index of 1.8 or less comprises exposing a substrate (210) to sequences of a non-hydroxylated silicon-containing precursor, activated oxygen species, and metal-containing precursor until a mixed metal-silicon-oxide film having a thickness of 500 Angstroms or less is formed on the substrate.
