On the other hand, it is preferable that the sheet pieces 7 and 8 are made of a material having a gas barrier property in order to maintain the quality of the contained items in addition to the heat-weldability, and further, heat resistant to cope with the contained items such as retort foods. It is preferable that it consists of the material which has property.

  As the sheet pieces 7 and 8 having such properties, for example, a laminated film of three or more layers composed of an inner layer having heat weldability, an intermediate layer having gas barrier properties, and an outer layer on the surface can be cited. Here, as the inner layer, polypropylene resin or the like is used, and as the middle layer, polyvinylidene chloride resin, polyvinyl alcohol resin, ethylene vinyl alcohol copolymer, aluminum foil, vapor deposited film of an inorganic material such as silicon oxide, or the like can be given. As the outer layer, a film made of a polyester resin or the like can be adopted in consideration of the necessity of printing.

  If at least the sheet pieces 7 and 8 have gas barrier properties, there is no risk of gas such as oxygen entering the storage chamber 2, and it is possible to reliably prevent oxidation and alteration of the objects to be stored in the storage chamber 2. The contents to be contained can be stored for a long time.

  The partition connection portion 10 is continuously provided with passage connection portions 13 and 13 that form inclined portions 12 and 12 that extend from the left and right side edge portions 5a and 5b of the storage chamber sheet portion 5 toward the extraction tool 3. As a result, the object to be accommodated flows along the inclined portion 12, whereby the object to be accommodated is easily poured out from the accommodation chamber 2.

  In the main body of the packaging bag 1, the longitudinal adhesive portions 14, 14 of the side edge portions 5 a, 5 b of the storage chamber sheet portion 5 are cut and partly connected to the partition connection portion 10 via the passage connection portions 13, 13. The continuous substantially L-shaped notches 15 and 15 which bite in are provided, and the advancing direction is the vertical direction.

  Further, a lateral cut or notch 16 is provided above the left and right side edges 6a and 6b of the sealing chamber sheet portion 6 so as to be cut to an intermediate portion of the width of the longitudinal adhesive portions 14 and 14. ing. Here, the cut or notch 16 that extends in the lateral direction may be at least one of the left and right sides.

  In the first embodiment, the pouring tool 3 is provided in the central portion of the packaging bag 1 and the inclined portions 12 are provided on the left and right sides of the pouring portion 3. However, the present invention is not limited to this, and the pouring tool 3 is not limited thereto. May be provided on either the left or right side of the packaging bag 1, and the inclined portion 12 may be made one.

  Next, the usage method of the packaging bag 1 which concerns on Embodiment 1 which has the above structures is demonstrated.

  When it is going to pour the contents of the packaging bag 1 according to the first embodiment from the pouring part 11 of the pouring part 3 to the outside, first, the part of the pouring tool 3 is grasped with one hand and packaged. When the bag 1 is fixed and the lateral connection 19 outside the notch 16 is picked by the fingertip of the other hand and is pulled away from the main body portion of the packaging bag 1, the lateral notch or notch 16 A force for tearing the sealed chamber 4 acts along the traveling direction (imaginary line X in FIG. 3). Therefore, the upper end side of the sealing chamber 4 is pulled away from the main body portion of the packaging bag 1 along the direction of travel of the horizontal cuts or notches 16, and the upper end side of the sealing chamber 4 is opened.

  Next, following the opening operation on the upper end side, the packaging bag 1 is fixed by grasping the portion of the pouring tool 3 with one hand, and the passage connecting portion outside the notch 15 extending vertically with the fingertip of the other hand When picking 13 and pulling it away from the main body portion of the packaging bag 1, a force acts to tear the sealed chamber 4 upward along the traveling direction of the cut 15 (imaginary lines Ya and Yb in FIG. 3). By performing this operation on both the left and right sides of the packaging bag 1, the vertical adhesive portions 14, 14 of the left and right side edges 6 a, 6 b of the sealing chamber sheet portion 6 are formed in the packaging bag 1 along the traveling direction of the cuts 15, 15. Pulled away from the main body, the left and right sides of the sealed chamber 4 are opened.

  In any of the horizontal opening operation and the vertical opening operation described above, when tearing the sheet pieces 7 and 8 of the sealing chamber sheet portion 6, there is no extraction tool 3 that becomes an obstacle in front of the tearing direction. Sheet pieces 7, 8 are torn cleanly. After that, since the sealing chamber sheet portion 6 of the opened sealing chamber 4 is opened so as to open outward, the pouring tool 3 can be sufficiently exposed from the sealing chamber 4 as shown in FIG. A sufficient working space around the portion 11 is ensured.

  As a result, even when an object to be contained such as a nutrient is administered to a patient, the plug 13 of the pouring tool 3 is twisted to cut the thin portion 12 and the plug 22 is removed from the pouring tool 3 for pouring. After opening the pouring hole of the part 11, the insertion port 21 of the connection cap 20 is fitted into the pouring part 11, so that an object to be contained such as a nutrient is poured out from the pouring tool 3. Work can be done easily.

  As described above, according to the packaging bag 1 according to the first embodiment, the sealing chamber 4 starts from the lateral cuts or notches 16 provided in the vertical connection portions 14 and 14 on the left and right sides of the sealing chamber 4. The upper lateral connection 19 can be removed. Moreover, since the vertical connection parts 14 and 14 on both the left and right sides can be removed by the vertical cuts 15 and 15 provided in the partition connection part 10 which is the boundary between the sealed chamber 4 and the storage chamber 2, etc. The sealing chamber 4 can be easily opened without using the cutting tool, and the pouring tool 3 can be sufficiently exposed. Furthermore, since the storage chamber sheet portion 5 is bonded to the partition connection portion 10 and the passage connection portions 13 and 13 so as not to be peeled off, the storage chamber 2 is opened by tearing the sealed chamber 4 starting from the notches 15 and 15. However, the container 2 is not opened.

  Further, when the sheet pieces 7 and 8 have gas barrier properties, they are shut off from the outside air, and a gas such as oxygen enters the storage chamber 2 and the sealed chamber 4 to oxidize and change the food inside. Therefore, it can be stored at room temperature and stored for a long time in a state where the heat-sterilized state is maintained.

  Further, unlike the conventional case where the perforation is provided in the sealed chamber, the packaging bag 1 according to the first embodiment does not have a fragile portion in the sealed chamber 4, so that the dispensing tool 3 may accidentally touch the air. Will be kept hygienic.

  Next, the manufacturing method of the packaging bag comprised as mentioned above is demonstrated.

With the pouring tool 3 arranged so that the mounting portion 9 is horizontal, the mounting portion 9 of the pouring tool 3 and the inner surfaces of the sheet pieces 7 and 8 and the inner surfaces of the sheet pieces 7 and 8 on both the left and right sides of the mounting portion 9 It is heat-welded with a sealing device so that it cannot be peeled off. Further, the inner surfaces of the side edge portions 6a and 6b of the sealed chamber sheet portion 6 and the inner surfaces of the upper edge portion 6c are heat-welded with a sealing device.

  The means for heat-welding the storage chamber 2 and the sealing chamber 4 so as not to peel and the means for heat-welding the attachment portion 9 of the pouring tool 3 and the inner surfaces of the sheet pieces 7 and 8 so as not to peel are generally a packaging bag made of a resin film. What is necessary is just to employ | adopt the sealing apparatus using the heated roller and board | plate material used when forming.

  It should be noted that the sheet pieces 7 and 8 and the pouring tool 3 are bonded at the same time by the thermal welding and the bonding process by the thermal welding for forming the sealed chamber 4 or following these bonding processes. A partition connection 10 that partitions the storage chamber 2 and the sealing chamber 4 by thermally welding the inner surfaces of the edges 5a, 5b and the lower inner surfaces of the left and right shoulders 5e, 5f of the upper edge 5c with a sealing device. The vertical connection portion 14, the horizontal connection portion 19 and the passage connection portion 13 are formed.

  In addition, a step of cutting an unnecessary portion to represent the predetermined shape of the packaging bag 1 is performed. If the packaging bag 1 according to the first embodiment shown in FIG. A cutting operation for forming a circle is performed.

  In addition, the longitudinal adhesive portions 14 and 14 of the side edge portions 5a and 5b of the storage chamber sheet portion 5 are cut simultaneously with this cutting process or before and after the cutting operation, and the section connection is made via the passage connection portions 13 and 13. Consecutive substantially L-shaped cuts 15 and 15 that bite into a part of the portion 10 are formed.

  Through the above steps, the packaging bag 1 in a state in which the object to be accommodated with the lower end portion 5d of the accommodation chamber 2 opened is not completed.

  Next, an object to be stored such as medicine or fluid cooked food is filled from the opened lower edge 5d of the storage chamber 2 using a filling device, and then the lower edge 5d is heat-welded so as not to be peeled off. Thus, the packaging bag 1 in which the object to be stored such as the intended medicine or food is stored in the storage chamber 2 is completed. In the case where the object to be stored is a food that requires retort sterilization, the food bag stored in the storage chamber 2 is stored by heating the packaging bag 1 in which the object is stored in a heating steam kettle or the like. The product will be sterilized.

According to the manufacturing method of the packaging bag 1 according to the first embodiment, the longitudinal adhesive portions 14 and 14 of the side edge portions 5a and 5b of the storage chamber sheet portion 5 are cut and partitioned via the passage connection portions 13 and 13. The continuous substantially L-shaped cuts 15, 15 that bite into a part of the connecting portion 10 are formed of a single cutting blade having a predetermined outer shape and a shape of the substantially L-shaped cuts 15, 15 on the main body of the packaging bag 1. By using it, the body of the packaging bag 1 can be processed at the same time as the process of forming a predetermined outer shape and the process of forming the substantially L-shaped cuts 15 and 15, so that special equipment other than cutting is required. do not do. Therefore, the packaging bag 1 which tears the sheet | seat pieces 7 and 8 of the sealing chamber 4 neatly and can fully expose the extraction | pouring part 11 can be manufactured cheaply.
