Packaging bag with self-closeable outflow port, and method of manufacturing the packaging bag
US 7866886 B2
FIG. 2 (B) is a model diagram showing another example of the method of the present invention for manufacturing a pouch that has a self-closable pouring spout. This example differs from the pouch manufacturing method shown in FIG. 2 (A) as follows: namely, in the heating part 21 of the portion of the heat sealing head that forms the pouring spout 3 of the pouch 1, a non-pressing part 22 is disposed as a hollow part in the position corresponding to the non-heat-sealed part 6 of the pouring spout passage 4, and a thin metal plate 29 consisting of aluminum or the like is interposed between the elastic pressing member 24 and the glass cloth substrate 25; furthermore, this glass cloth substrate 25 which is impregnated with Teflon, fired and coated on one side with a silicon rubber bonding agent is interposed between the plastic film 26 and heating part 21 instead of the glass cloth substrate 27 which has a Teflon sheet layer disposed on the surface. The other structures are the same. The pouring spout 3 is formed by clamping the plastic films 26, 26 by means of the heating part 21 and pressing part 23, closing the heat sealing head, and heat sealing the plastic films 26, 26 by heating and pressing. In this case, for example, the thin metal plate 29 can be formed from an aluminum plate with a thickness of approximately 0.1
to approximately 0.3
; however, a plate of the optimal material and thickness is selected and used in accordance with conditions such as the pressure during heat sealing and the like.
The valve members 103 which are fed out from a partitioning member supply mechanism that includes valve member rolls 104 disposed to the side and corresponding pay-out means are web-form members that are thermally weldable on both sides, and the running upper-side body member 101 and lower-side body member 102 are temporarily mounted inside spaces that are greatly separated from each other. After the valve members 103 are symmetrically folded back and superimposed with the center lines in the longitudinal direction as the fold-back lines, these valve members 103 are cut in two along the fold-back lines, and are thus formed into a pair of narrow web-form valve members 103 a and 103 b. In the position C3, the pair of valve members 103 a and 103 b are sealed to each other by a valve member sealer 105 consisting of a pair of sealing heads 105 a and 105 b, so that a valve seal 149 is formed in the region on the outside in the lateral direction of the web; here, a portion is left unsealed so that a valve passage 150 is formed between the pair of valve members 103 a and 103 b.
Next, the valve members 103 a and 103 b are clamped and superimposed between the facing body members 101 and 102; simultaneously, a sealing preventing member 106 is inserted between the valve members 103 a and 103 b. In the position D3, the superimposed body members 101 and 102 and pair of valve members 103 a and 103 b are pressed and heated by a valve-body sealer 107 used as a body-partitioning sealer consisting of a pair of sealing heads 107 a and 107 b. In this case, the respective valve members 103 a and 103 b are both welded to the respectively corresponding body members 101 or 102 on the inside in the lateral direction of the web, so that a valve-body seal 151 is formed. Both of the valve members 103 a and 103 b are heated and pressed by the valve-body sealer 107; in this case, however, since the sealing preventing member 106 is interposed, the facing surfaces of the valve members 103 a and 103 b are not thermally welded to each other. The top-bottom direction of the manufactured pouches P3 is oriented perpendicular to the conveying direction of the body members 101 and 102 and valve members 103, and the region in which the valve seal 149 is formed is disposed along this conveying direction, so that the sealing preventing member 106 can be disposed along the conveying direction without interfering with the vale seal 149 that constitutes the already-sealed portion of the valve members 103, thus making it possible to perform valve-body sealing 151 during continuous pouch manufacture.
Following the formation of the pouring spout periphery seal 144 and bottom seal 156 at the position F3, easy opening working around the pouring spout 141 is performed in the process 110. Furthermore, after mold release of the periphery of the pouring spout is performed by the pouring spout mold release cutter 111 in the position G3 so that a branched part 161 is formed in each pouch, folding back of the branched part 161 is performed by the fold-back molding part 131 via the position H3 and position 13. In the position J3 where the folding back of the branched part 161 is completed, the filling opening fold-back in which the folded part 162 is folded back toward the outside in the lateral direction is completed, and a temporary fastening punch hole treatment of the branched part is performed by a branched part temporary fastening punch 132 between pouches that are adjacent in the pouch feeding direction. The branched part temporary fastening punch 132 consists of a punch 132 a and a punch receiver 132 b that is disposed facing this punch 132 a.
In the position K3 which is located immediately downstream from the position J3, a lateral sealer 112 extending in a direction that cuts across the body members 101 and 102 is disposed above and below the body members 101 and 102. The lateral sealer 112 consists of a pair of sealing heads 112 a and 112 b that can move upward and downward, and forms a lateral seal 142 that welds both body members 101 and 102 in a state of continuous connection to the pouring spout periphery seal 144 at both ends, straddling the portions of the body members 101 and 102 that form two pouches P3 and P3 that are adjacent in the feeding direction. In the portions where the bottom member 121 is present, the lateral sealer 112 presses and heats the body members 101 and 102 in a state in which the bottom member 121 is clamped. A lateral seal 142 is formed by the lateral sealer 112 in the cross-sectional region excluding the portions where the branched part temporary fastening punch hole treatment is performed. The lateral seal 142 is formed once across the two rows between the two pouches P3, P3 that are adjacent to each other in the feeding direction of the packaging material.
The retaining plate 224 on the side of the front end is formed in a flattened annular shape that surrounds the front end part of the main plate 221, and a gap 226 that allows the passage of the web 201 is formed around the front end part of the main plate 221. The retaining plate 224 is supported on the machine frame 228 via a supporting member 229 c that extends from the supporting member 229 a.
The inside guide 220 guides only the bending deformation of the main body part 203 of the web 201, and does not directly guide the folded-back parts 204, 204; however, by causing the bending deformation of the main body part 203, inside guild3e 220 exerts an effect that narrows the folded-back parts 204, 204 in the inside fold-back direction. The retaining plate 224 acts substantially as a former that performs fold-back, and the inside guide 220 performs a guiding function without generating any substantial tension in the web 201 in this case other than the tension used for feeding. The folded-back parts 204, 204 are not directly guided by the inside guide 220 or of course by the other guides either; however, these folded-back parts 204, 204 are folded back in a natural shape without the generation of any substantial tension, and assume a state in which these parts are folded back with sufficient accuracy when they pass over the retaining plate 224. However, the inside guide 220 may also be constructed as an inside guide which has a structure that directly guides the folded-back parts 204, 204 from the inside, i.e., which has a guide surface that is complementary to the guide surface consisting of the guide walls 212 through 215 and central portion 216 of the outside guide 211 as an inside guide part of the outside guide 211 shown in FIG. 22. The length of the pass line of the main plate 221 is set so that this length is the same as the length of the pass line of the folded parts 204, 204.
