In the flexible package bag provided with the film-shaped one-way pouring nozzle protruding from a side portion, corner portion or top portion of the package bag body, a coating layer made from a water-repellent material or an oil-repellent material is provided on an outer surface of the film-shaped one-way pouring nozzle, while a wet-treated layer is provided on an inner face of a pouring path in the film-shaped one-way pouring nozzle. | 08-19-2010 |
20110049184 | PACKAGE PROVIDED WITH LIQUID POURING NOZZLE - There is provided a package bag provided with a liquid pouring nozzle wherein permanent deformation of a pouring path for a packing material of the liquid pouring nozzle in a swollen direction is prevented surely to completely prevent accidental invasion of air into a package bag main body in the pouring of the packing material but also the self-sealing one-way function can be sufficiently developed in the pouring stop of the packing material. The package bag according to the invention is characterized in that the liquid pouring nozzle is constructed by laying front and rear laminate films, each of which films comprising a base film layer and a high-melting sealant layer and a low-melting sealant layer sandwiching the base film layer therebetween so as to face the high-melting sealant layers to each other and fusion-joining them at their peripheral portions other than base end sides to each other, and the base end portion of the liquid pouring nozzle is fusion-joined to a sealant layer on an inner surface of a soft package bag main body through low-melting sealant layers on the outer surface of the nozzle at a posture of protruding the nozzle from a side portion of the soft package bag main body, and also in that the opposed high-melting sealant layers in the base end portion of the liquid pouring nozzle are temporarily fused to each other. | 03-03-2011 |
20110110613 | FLEXIBLE PACKAGE BAG PROVIDED WITH ONE-WAY FUNCTIONING NOZZLE AND LIQUID MATERIAL-FILLED PACKAGING STRUCTURE - Disclosed is a non-self standing type flexible package bag provided with a film-shaped one-way pouring nozzle which is excellent not only in the non-return function and liquid cutting properties but also in the pouring property of a liquid packing material as a filling substance (capable of smoothly pouring the packing material in the bag until the end). The flexible package bag is constituted by protruding the film-shaped one-way pouring nozzle from a side portion of a package bag main body in which a laminate film in a non-seal portion of the package bag main body has an irregular inner surface in at least an upper part thereof or in the vicinity of a side edge side the film-shaped one-way pouring nozzle. | 05-12-2011 |
20120114269 | SELF-STANDING LIQUID PACKAGE BAG WITH A FLAT FILM VALVE - A self-standing liquid package bag provided with flat film valve is provided at a single use form by self-standing a liquid package bag with a film valve having a one-way function without being required to house and fix in another outer package vessel and obstructing the one-way function of the film valve. The self-standing liquid package bag of the invention is formed by protrudingly disposing a flat film valve having a one-way function, which is subjected to a wetting treatment at full inner faces in a pouring path and a portion adjacent to a fused part near to the pouring path, on an upper part or top part of at least one side edge of a bag body portion and disposing a self-standable bottom portion at bottom thereof. | 05-10-2012 |
20120152462 | DEVICE FOR ATTACHING ONE-WAY POURING NOZZLE - There is provided a device for attaching a one-way type pouring nozzle, which includes a simple and small-size mechanism capable of efficiently fusion-joining the one-way type pouring nozzle to a film for package bag. In this device, a nozzle template film formed with a plurality of one-way type pouring nozzles templated by tear-inducing flaws is fed to a continuously running film for package bag to fusion-join a base portion of each of the one-way type pouring nozzles through its outer sealant layer to an inner sealant layer on one-sided portion of the film for package bag, while an unwanted portion of the nozzle template film is cut out and removed. The device also includes a pair of fusion rollers pushing and fusion-joining the one-way type pouring nozzle in the nozzle template film to the running film for package bag under the running at equal speed, and the fusion roller pair is constituted with a heating roller always energizing toward the side of the running path of the film for package bag, and a heat roller for attachment provided with protrusions intermittently pushing the film for package bag to positions of one-way type pouring nozzles in the nozzle template film on the heating roller. | 06-21-2012 |
20130223768 | PACKAGE BAG AND METHOD FOR FILLING AND PACKING LIQUID MATERIAL TO BE PACKED - There are provided a package bag capable of surely preventing stay of ambient air or the like in the package bag and intake thereinto even in the filling by handwork or the like of an operator as well as a method for filing and packing the liquid material to be packed into the package bag. A package bag is characterized by comprising a bag main body made of thin laminate films for packing, a fusion part formed at a position spaced from a bottom portion of the bag main body not forming a nozzle through fusion and extending in a widthwise direction of the bag main body, an insert port for a pipe-like filling nozzle provided in a middle portion of the fusion part, a filling part of one-way function formed between the fusion part and an opening end of the bag main body. | 08-29-2013 |
20130315508 | FLEXIBLE PACKAGING BAG - A flexible package bag is equipped with a film-shape non-return nozzle by which a pouring amount of a liquid packed material can be stabilized by rectifying a pouring flow of the liquid packed material. The pouring performance and breaking resistance of the bag can be improved by reinforcing the film-shaped non-return nozzle. A flexible package bag is formed by fusion-joining a base end portion of a film-shaped non-return nozzle having an outer non-return function of preventing penetration of ambient air into the bag to inner surfaces of a side portion of a main package bag body composed of plastic laminate films and projecting therefrom. A seal section for rectification/reinforcement formed by fusing two opposed plastic laminate films is disposed at a position near to the main package bag body including a lower portion of a fused section to the base end portion of the film shaped non-return nozzle. | 11-28-2013 |
20140217119 | PACKAGE BAG, PACKAGE BODY USING THE SAME, AND METHOD OF MANUFACTURING SAID PACKAGE BAG - A package bag having: a flexible main package bag body formed by fusion-joining a sealant layer of a packaging film of laminated structure including a base film layer and the sealant layer; and a one-way pouring nozzle having a self-sealing function, which is constructed by a planar laminated film having thin thickness including sealant layers on front-back both sides. The one-way pouring nozzle is projected laterally from the flexible main package bag body by fusion-joining a base end portion of the one-way pouring nozzle to an inner surface of a side portion of the main package bag body, including: a projection portion extending continuously from the flexible main package bag body, with which whole one-way pouring nozzle is covered from both of front surface side and a back surface side; and a tear-inducing flaw extending across a center portion in a projection direction of the one-way pouring nozzle. | 08-07-2014 |
