The encapsulating bag 600 is formed into a bag shape by bending a central portion 62 of a single rectangular base material 61 and thermocompressing the periphery thereof. A synthetic resin film such as polypropylene is used. The base material 61 may have a structure in which two base materials are stacked and the periphery (except for the lower end edge) is thermocompression-bonded as in the first embodiment (not shown). In this case, it is desirable that the portion corresponding to the central portion 62 between the stacked substrates is thermocompression bonded after the contents are put therein. Further, the fastener 63 forms the enclosing region 64 in a state where the enclosing bag 600 is formed, and is bonded from one end 66 of the base member 61 at a predetermined interval.

In the fastener 63, a columnar protrusion 68 is formed in a straight line on the surface of the strip-shaped tape part 67, and a protrusion having a groove 70 corresponding to the protrusion 68 is formed in a straight line in the corresponding tape part 69. The inside of 70 is cylindrical, and has a structure in which the cylindrical projection 68 is sealed by fitting into the groove 70. The fastener 63 adheres one tape portion 67 to a predetermined position of the base member 61 in a state where the protrusion 68 is fitted in the groove 70. Thereafter, as shown in FIG. 13B, when the base material 61 is bent, the other tape portion 69 is bonded to the surface of the base material 61 at a predetermined position.

  In the vicinity of both end portions of the substrate 61, cutting grooves 71 serving as cutting line portions are provided in parallel and linearly to both end portions. The cutting groove 71 may be linear or perforated. Further, the cutting grooves 71 are provided on both end portions of the base member 61 with respect to the fastener 63. The cutting groove 71 is formed by a press machine or laser processing. In addition, the cutting groove 71 does not penetrate in the thickness direction of the base material 61 of the encapsulating bag 600, and is cut into the base material 61 halfway. For this reason, even if the cutting groove 71 is provided, the sealing of the enclosing region 64 is maintained. In addition, the both ends of the cutting groove 71 may be cut so as to be easily cut by a finger (not shown, the same applies to Embodiments 6 and 7 below).

Further, as shown in FIG. 13A, semicircular knob portions 72 and 73 are attached to the base material 61. Further, the straight portions 72a and 73a which are part of the knob portions 72 and 73 are bonded between the cutting groove 71 and the fastener 63, and the arc portions 72b and 73b which are other portions of the knob portions 72 and 73 are cut.

Since the zipper 63 can be easily opened also by this enclosing bag 650, it is particularly useful for elderly people who are difficult to work with.

(Embodiment 6)
FIG. 20 is a partial cross-sectional view showing an encapsulating bag according to Embodiment 6 of the present invention. FIG. 21 is an explanatory view showing a method of manufacturing the encapsulating bag shown in FIG. The enclosing bag 700 is characterized in that knob portions 83 and 84 are formed on the tape portions 81 and 82 of the fastener 80. In the fastener 80, as shown in the fifth embodiment, the columnar protrusion 68 is formed in a straight line on the surface of the strip-shaped tape portion 81, and the protrusion having the groove 70 corresponding to the protrusion 68 corresponds to the tape. It is formed in a straight line on the portion 82, and the inside of the groove 70 has a cylindrical shape, and the columnar protrusion 68 is sealed by being fitted into the groove 70.

  Semicircular knob portions 83 and 84 are integrally formed with the pair of tape portions 81 and 82 of the fastener 80, respectively. That is, the material is punched and formed with the knob portions 83 and 84 projecting from the tape portions 81 and 82. Further, the knob portions 83 and 84 are formed so as to be shifted in the length direction of the fastener 80. For this reason, the knob parts 83 and 84 are positioned so as to be displaced in a state in which the protrusion 68 is fitted in the groove 70 of the fastener 80. When attaching the fastener 80 to the base member 61, first, as shown in FIG. 21, one tape portion 81 is attached to the predetermined portion of the base member 61 in a state in which the projection 68 is fitted into the groove 70 (integral state). Glue in position. Then, the other tape portion 82 is bonded to a predetermined position of the substrate 61 by folding back at the central portion 62 of the substrate 61.

The upper end edge 61a and the left and right end edges 61b of the substrate 61 are thermocompression bonded. In addition, when putting the contents in the encapsulating bag 700, after bending and forming the bag shape, the central portion 62 is cut, the contents are put, and the central portion 62 is thermocompression bonded. Moreover, in the case of a configuration in which two substrates are stacked and the periphery thereof is thermocompression bonded, the upper edge and the left and right edges are crimped first, and after the contents are put, the lower edge is crimped (not shown). In the vicinity of both end portions of the substrate 61, cutting grooves 71 serving as cutting line portions are linearly provided in parallel to both end portions. The cutting groove 71 may be linear or perforated. Further, the cutting groove 71 is provided on both end portions of the base member 61 with respect to the fastener 80. The cutting groove 71 is formed by a press machine or laser processing. In addition, the cutting groove 71 is not penetrated in the thickness direction of the base material 61 of the enclosing bag 700, but is cut into the base material 61 halfway. For this reason, even if the cutting groove 71 is provided, the sealing of the enclosing region 74 is maintained.

  The fastener 80 is bonded to the base material 61 at the tape portions 81 and 82 so that the knob portions 83 and 84 are covered with the cutting line portion. The knob portions 83 and 84 are not bonded to the base material 61. Further, the upper ends of the knob portions 83 and 84 are prevented from interfering with the crimping portion 74 at the top of the enclosing bag. In addition, the shape of the knob parts 83 and 84 is not limited to a semicircular shape. For example, a triangle or a rectangle may be used.

Since the enclosing bag 700 is in a state in which the knob portions 83 and 84 are encapsulated inside the enclosing bag 700, the outer surface of the enclosing bag 700 is clean and the surface of the enclosing bag 700 is not caught. For this reason, the knob parts 83 and 84 are not removed from the enclosing bag 700 by an external force. In addition, since the fastener 80 and the knob portions 83 and 84 are integrally formed, the knob portions 83 and 84 can be formed simply by attaching the fastener 80 to the base member 61, so that it is easy to manufacture.

  Next, in order to cut the cutting groove 71 of the enclosing bag 800, one end of the upper edge portion 61a of the enclosing bag 700 is pinched and pulled. Thereby, the upper edge portion 61a is cut off from the enclosing bag 700 along the cutting groove 71, and the knob portions 83 and 84 appear from the upper edge portion 61c newly formed by the cutting groove 71 as shown in FIG. When the user opens the fastener 80, the user grips one knob portion 83 with the right hand and the other knob portion 84 with the left hand, and pulls both to open. Accordingly, the fastener 80 is completely opened by starting to open from the vicinity of the knob portion and continuing to pull the knob portions 83 and 84. Since the knob portions 83 and 84 are integrally formed with the tape portions 81 and 82 of the fastener 80, a force can be directly applied to the tape portions 81 and 82 of the fastener 80 by pulling the knob portions 83 and 84. The fastener 80 can be easily opened and the knob portions 83 and 84 are prevented from being peeled off from the base material 61.

As described above, according to the enclosed bag 700 of the present invention, the knob portions 83 and 84 can be easily provided, and the fastener 80 can be easily opened by the knob portions 83 and 84. This is particularly useful for elderly people who have difficulty in hand freedom.

(Embodiment 7)
FIG. 23 is a cross-sectional view showing an enclosing bag according to Embodiment 7 of the present invention. The encapsulating bag 800 is formed by superimposing two base materials, which are a front portion 1 and a back portion 2, and sealing the outer edges of the four sides to seal the upper edge crimp portion 3, the left and right edge crimp portions, and the lower edge portion. A crimping part (not shown) is formed into a bag shape. For the base material, for example, a polyester resin, polyamide resin, polypropylene resin film or the like is used.

The enclosing bag 800 is provided with a fastener 6 on the upper portion of the enclosing region 5 that encloses food or the like. In the fastener 6, cylindrical protrusions are formed in a straight line in the lateral direction of the enclosing bag 800 on the inner side of the front portion 1 of the base material, and the protrusions having grooves corresponding to the protrusions are the back part of the base material of the enclosing bag 800. 2 is formed in a straight line in the horizontal direction. The inside of the groove is cylindrical, and the fastener 6 is sealed by fitting the cylindrical protrusion into the groove. In addition, the structure of the fastener 6 is not limited to this, You may use a well-known fastener. On the other hand, when the front portion 1 and the back portion 2 of the enclosing bag 800 are pulled apart, the protrusion is removed from the groove and the fastener 6 is opened.

  Cutting grooves 807 and 808 serving as cutting line portions are linearly provided in the lateral direction of the enclosing bag 100 on the fasteners 6 of the front portion 1 and the back portion 2. The cutting grooves 807 and 808 may be linear or perforated. The cutting grooves 807 and 808 are formed by a press machine or laser processing. Further, the cutting grooves 807 and 808 are not penetrated in the thickness direction of the base material of the encapsulating bag 800, but are cut to the middle of the base material. For this reason, even if the cutting grooves 807 and 808 are provided, the sealing of the enclosing region 5 is maintained.

In addition, the front portion 1 has a slack portion 801 that uses an extra base material than the back portion 2. The slack portion 801 may be swollen as shown in the figure, or may be folded and planar. However, in order to prevent the shape from returning when stretched, it is preferable not to make a tight crease. The cutting grooves 807 and 808 are located above the slack portion 801.

  The user pinches the part slightly above the fastener 6 and the upper edge of the encapsulating bag 800 with a finger and separates it along the cutting grooves 807 and 808. As a result, the upper base material portion is cut along the cutting grooves 807 and 808. When the slack portion 801 is extended, the upper end portion 802 of the front portion 1 is positioned on the back portion 2 as shown in FIG. The user opens the fastener 6 by pinching the upper end portion 802 with the right hand to release it from the back portion 2 and pulling the back portion 2 with the left hand so as to open both.

  As described above, according to the enclosing bag 800 of the present invention, since the slack portion 801 is extended and the upper end portion 802 is easily pinched, the fastener 6 of the enclosing bag 800 can be easily opened.
