Description

  The present invention relates to a two-chamber structured bag having an easy-opening property in which two kinds of contents such as main contents and semi-contents are stored in the same bag.

  Conventionally, for example, as a packaging for storing two kinds of contents such as a main contents in a wharf and a semi-contents in an oxygen scavenger, the contents are stored in a vacuum or compressed air plastic container. Deep-drawing packaging with heat-sealed top film sealed with top film, blister packaging with heat-bonded container film on mount for placing contents, bag-making with vertical bag-filling machine Pillow packaging was widely used.

  However, in the above-described deep-drawn packaging, blister packaging, and pillow packaging, if two types of contents are stored together, the two types of stored contents come into contact with each other, and the contents become dirty or poor in appearance. It was. If the contents require gas barrier properties, deep drawing packaging and blister packaging have a heating process and a molding process, the filling speed of the contents is slow, and the thickness of the corner of the molded product is thin. However, the barrier property of the package may be lowered, and in order to prevent the barrier property from being lowered, the use of a thick film increases the manufacturing cost and increases the amount of waste during disposal after use. There was a case. Further, in pillow packaging, there is a problem that the tightness is not present and the protection of the content is poor, the unsealing property at the time of opening is poor, and the content pops out of the packaging bag due to an impact at the time of opening.

  The present invention solves the above-mentioned conventional conventional deep-drawing packaging, blister packaging, pillow packaging, etc., the two types of contents do not come into contact, and the contents are well protected, It is an object of the present invention to provide a two-chamber structured bag that can be filled with contents at high speed and can be suspended easily.

  That is, according to the first aspect of the present invention, a roll of a bag body film and a roll of a lid film having an easy peel property are loaded into a bag making and filling machine, and the film is formed at a central position in the left-right direction of the bag body film. The first contents are intermittently continuously placed at predetermined positions in the flow direction, and the groove-shaped second shape is wrapped around the first contents by folding the film main body on both the left and right sides of the bag body film. 1 content storage chamber is formed, and the second content is placed on the folded inner surface of the bag body film directly above the first content storage chamber, and on the upper left and right side edges of the bag body film. , A flat outward facing seal portion is provided in the film flow direction to form a second content storage chamber, and heat sealing is performed by overlapping the right and left side edge portions of the lid material film in the film flow direction on the seal portion, Contents listed above The bag main body film and the lid material film are heat-sealed at a seal portion in a left-right direction at a predetermined position in the film flow direction to seal a packaging bag, and the easy-openability characterized by being cut and separated one by one This is a two-chamber structured bag.

According to a second aspect of the present invention, a bag body film roll and an easy-peeling roll film roll are loaded into a bag making and filling machine, and the film is formed at a central position in the left-right direction of the bag body film. The first contents are intermittently continuously placed at predetermined positions in the flow direction, and the groove-shaped second shape is wrapped around the first contents by folding the film main body on both the left and right sides of the bag body film. 1 content storage chamber is formed, and on the folded inner surface of the bag main body film just above the first content storage chamber, a paperboard whose upper and lower surfaces are heat-sealable is placed, and the upper end of the bag main body film is placed. The left and right side edges and the left and right side edges in the film flow direction of the lid film are overlapped and heat-sealed, and at the same time, the inner surface of the lid film, the upper surface of the paperboard, the lower surface of the paperboard, and the lid material film Inside Heat sealing the sealing portion in the left and right direction at a predetermined position in the film flow direction between the bag body film and the lid material film between the contents placed above, and sealing the packaging bag, A two-chamber structure with easy opening, characterized in that a hanging hole is provided in the central portion in the left-right direction where the lid material film, the paperboard, and the bag body film are heat-sealed and separated one by one. It is a bag.

  According to a third aspect of the present invention, the bag main body film is a laminated film including a high barrier film layer, and the easily openable 2 according to the first aspect or the second aspect of the invention. It is a chamber structure bag.

  The easily opened two-chamber structure bag of the present invention is folded on the left and right side surfaces of the bag body film to form a first content storage chamber below, and directly above the first content storage chamber. A second content storage chamber is provided, and the space between the first content storage chamber and the second content storage chamber is blocked by the folding of the bag body film, so that it is stored in the first content storage chamber. The first content and the second content stored in the second content storage chamber do not come into contact with each other, and the content is not soiled or deteriorated in appearance.

  In addition, the two-chamber structured bag with easy opening according to the present invention is a bag body film and a lid material film that are folded on the side surface, heat-sealed, and made into a bag and sealed. Unlike blister packaging, where the content storage chamber is molded by vacuum forming or pressure forming through a heating process, there are no thin parts, and the packaging barrier does not deteriorate during bag making. Good protection. In addition, when barrier property is especially requested | required of a packaging bag, the laminated | multilayer film containing a high barrier film layer can be used as a bag main body film.

  Moreover, the two-chamber structure bag with easy opening of the present invention is intermittently and continuously provided in the first groove-shaped content storage chamber of the bag body film continuously formed on the bag making and filling machine. The first contents are placed at a predetermined position, and the first contents storage chamber for wrapping the first contents is formed by folding the left and right sides of the bag body film, and directly above the first contents storage chamber. The second contents are placed on the folded inner surface of the bag body film, and the contents can be filled at high speed.

  Moreover, the easy-opening two-chamber structure bag of the present invention uses a laminated film having an easy peel property for the lid material film, and it is easy to open the packaging bag when opening the packaging bag. Yes, the contents do not pop out of the packaging bag due to the impact at the time of opening.

  Moreover, the two-chamber structure bag with easy opening of the present invention has a paperboard on which both upper and lower surfaces can be heat-sealed on the folded inner surface of the bag body film directly above the first content storage chamber. The top and bottom edges of the main film and the left and right edges of the cover film are overlapped and heat-heeled, and at the same time, the entire inner surface of the cover film, the upper surface of the paperboard, the lower surface of the paperboard, and the inner surface of the cover material film Heat sealing and sealing in the left and right direction at a predetermined position in the film flow direction between the bag body film and the lid material film between the placed contents and sealing the lid film, paperboard and bag body If the hole for suspending is provided in the center part in the left-right direction of the part heat-sealed with the film, it can be suspended.

  Next, an embodiment of the easy-opening continuous packaging bag of the present invention will be described in detail with reference to the drawings.
