20100210439 | DEVICE FOR CUTTING PACKING BAG, DEVICE FOR PRODUCING PACKING BAG AND METHOD FOR PRODUCING PACKING BAG - A cutter includes a male blade, a female blade, an advancement and retraction controller and a suction device. The male blade includes: a linear cutting portion linearly shaped with a predetermined thickness in a center part; a rounded cutting portion where a radius having a substantially arc shape in planar view is continuously formed from the linear cutting portion; and an end provided adjacent to the rounded cutting portion. The female blade has a fitting portion that is a hole conforming to the profile of the male blade in planar view and to which the male blade is fitted. On a lateral side of the female blade, an elongated hole for inserting a base film from one lateral side to the other lateral side is formed as an insertion portion. | 08-19-2010 |
20110089228 | CONTINUOUS WORKING DEVICE - A continuous machining device includes: a film machining mechanism that forms a hole in a film; a holding mechanisms being provided integrally with the film machining mechanism; a slider that supports the film machining mechanism and the holding mechanism in a reciprocative manner relative to a feeding direction of the film; and a return mechanism that returns the film machining mechanism and the holding mechanism to their respective original positions defined on the opposite sides to the feeding direction of the film. When the film is held by the holding mechanism, the film machining mechanism can be moved in synchronization with the film. Thus, after the hole is formed in the film by the film machining mechanism, the film machining mechanism and the holding mechanism can be returned to their respective original positions by the return mechanism as soon as the film is released from the holding mechanism. | 04-21-2011 |
20120085479 | MANUFACTURING METHOD FOR PACKAGING BAG WITH ZIPPER TAPE AND MANUFACTURING APPARATUS THEREFOR - A zipper tape member having a male engagement portion and a female engagement portion formed on a surface of an elongated belt-like tape is pulled out, and is punched and removed at a portion corresponding to the male engagement portion and a portion corresponding to the female engagement portion at predetermined intervals. The zipper tape member is cut between the male engagement portion and the female engagement portion by a cutting member to be separated into a male belt-like member and a female belt-like member. The male belt-like member and the female belt-like member are heat-sealed to a base film, and a packaging bag is formed by a bag-manufacturing device. This arrangement is unlikely to cause a length difference or a tension difference between the male belt-like member and the female belt-like member, so that the zipper tape can be heat-sealed without any crease or adhesion failure. | 04-12-2012 |

20100060843 | LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE - A liquid crystal composition is described, which satisfies at least one characteristic among high maximum temperature of a nematic phase, low minimum temperature of a nematic phase, small viscosity, large optical anisotropy, large dielectric anisotropy, large specific resistance, high stability to ultraviolet light, high stability to heat and so on, or is properly balanced regarding at least two of the characteristics. To provide an AM device having short response time, large voltage holding ratio, large contrast ratio, long service life and so forth, the liquid crystal composition has a nematic phase and contains a specific three-ring compound having a large optical anisotropy as a first component, a specific four-ring compound having a large dielectric anisotropy as a second component, and a specific two-ring compound having a particularly small viscosity as a third component. A liquid crystal display device containing the liquid crystal composition is also described. | 03-11-2010 |
20120181478 | LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE - A subject is to provide a liquid crystal composition that has a negative dielectric anisotropy and contains a specific 3-ring compound having a large optical anisotropy as a first component and a compound having a large negative dielectric anisotropy and containing a methyleneoxy group or pyran ring as a second component, and may contain a specific compound having a small viscosity as a third component and a specific compound having a large negative dielectric anisotropy as a fourth component, respectively, and a liquid crystal display device that contains the composition. | 07-19-2012 |

20110243481 | PACKAGING BAG WITH ZIPPER TAPE, DEVICE AND METHOD FOR MANUFACTURING PACKAGING BAG, AND BAND-LIKE MEMBER FOR BENDING - A packaging bag includes a male belt-like base edge and a female belt-like base edge which are abutted on each other. Accordingly, a base material film is bent between the male belt-like base edge and the female belt-like base edge, thereby reliably engaging a male engagement portion with a female engagement portion. According to a manufacturing device of the packaging bag, since a male belt-like member and a female belt-like member are bonded to a sheet of base material tape while the male belt-like base edge and the female belt-like base edge are substantially abutted on each other by first and second grooves, an adhesion operation can be conducted with accuracy. | 10-06-2011 |
20120201480 | ZIPPER TAPE, PACKAGING BAG WITH ZIPPER TAPE, METHOD FOR PRODUCING PACKAGING BAG WITH ZIPPER TAPE AND PRODUCTION DEVICE THEREFOR - After engagement of a male belt-like member and a female belt-like member are disengaged, a void portion is formed by punching the female belt-like member with a die. The female belt-like member having the void portion and the male belt-like member are re-engaged with each other and fed between a folded base material film that is continuously fed. A male belt-like base and a female belt-like base are heat-sealed. A seal bar heat-seals the base material film to form a bottom seal portion. A side seal bar heat-seals the base material film to form side seal portions. The cutter cuts the base material film in the middle of the side seal portions to produce the packaging bag in which three sides of the bottom seal portion and the side seal portions are heat-sealed. | 08-09-2012 |
20120207409 | EASY TO OPEN ZIPPER TAPE, AND PACKAGING BAG WITH EASY TO OPEN ZIPPER TAPE - A connecting portion is provided between a first thick portion and a second thick portion in a cutting portion. Further, a thinnest portion on which a stress can be concentrated is provided to the connecting portion. Accordingly, when tearing a base material film of a bag body, the connecting portion can guide a cutting line toward the thinnest portion to position the cutting line in the thinnest portion, so that the bag body can be easily opened. | 08-16-2012 |
20120314978 | ZIPPER TAPE AND PACKING BAG WITH ZIPPER TAPE - A thick portion is formed thick at an end of a female belt-like base near a containing space. To the thick portion near the containing space, a cut portion thinner than the female belt-like base is provided. To the cut portion near the containing space, a seal base that is thicker than the female belt-like base and is sealed to an inner surface of a bag body to which a male belt-like base is attached, is provided. Seal strength of the thick portion to the inner surface is lower than that of the seal base. The cut portion is provided to have a lower seal strength than that of the seal base. An area surrounded by the thick portion, the cut portion, the seal base and the inner surface becomes hermetically sealed. Even when external pressure is applied on the bag body, damages to the cut portion can be prevented. | 12-13-2012 |
20120321225 | ZIPPER TAPE AND PACKAGE BAG WITH ZIPPER TAPE - A head of a male member and a concave groove of a female member are engageable with and disengageable from each other and form a containing space inside a bag body. On an inner surface of the concave groove, there is provided a fusion layer that fuses an outer surface of the head and the inner surface of the concave groove facing each other, when foods are heat-sterilized for long storage. A peeling strength of the fusion layer only needs to be set by selecting a material of the fusion layer or setting dimensions of an area of the fusion layer such that the fusion layer does not require a large force for opening the bag, thereby providing a favorable opening feeling. The fusion layer provides air-tightness, so that the foods can be prevented from leaking out although a pressure within the containing space is increased in the heat sterilization. | 12-20-2012 |
