Field of the Invention The present invention relates to a bag having a 5-outlet port for attaching an outflow port to a bag body. [Prior Art Background of the Invention] You are attached with an outflow--not a same as a new one, and the bag body composed of a soft film of 10 15 20 is thermally fused and combined. Fig. 4 is a view showing a bag generally provided with an outflow port, that is, the bag system with the knot 2 is configured to include: a bag body 1 (Π, a laminated flexible thin: a., a shape = The bag body 'and the film ends constituting the seam are sealed and sealed, and the 'outlet port 103' is installed between the film ends of the bag body (9): , and the end portion of the bag is sealed with the heat and sealed. However, since the film portion 1 〇 4 描 j j j 面向 面向 面向 面向 面向 面向 面向 面向 面向 面向 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜 薄膜When the pressure of the contents rises or falls, the impact of the internal pressure wells in the inner body 101 is easy to be evaluated. The film portion will just expand greatly and the stress capacity is the stress mixture in the ΓΓ1ϋ2 and (4) parts. 1G5 of the boundary portion 1G5, in the special mouth seal 2: the edge portion 103a of the left and right sides is near the intersection point P of the boundary portion 丨〇5 at the outflow edge, and the approach is: heat: connect! = Γ, _1 (3) The flow outlet sealing portion 102 combines to break the film:::Gold degree (four)' and stress concentration 5 200824977 Accordingly, compared to the unmounted The bag of the outflow port and the bag with the outflow port have problems of resistance to pressure and poor drop impact resistance. Also, in the bag with the outflow port, the vicinity of the outflow port 103 is also taken out when the contents are taken out. The film portion 104 in the inside of the bag body 101 is liable to be automatically clogged with 5 and is difficult to take out the contents. In order to prevent automatic clogging, a plate-like or rod-shaped automatic clogging prevention tool 106 is conventionally inserted, however, this portion adds parts. In addition, the automatic blocking function is sometimes formed integrally with the outflow port and is difficult to form. 10 A technique for preventing stress concentration at the edge portion of the outflow port has been known so far as disclosed in Patent Document 1, In Patent Document 1, the shape of the inner edge portion of the outflow port that is thermally welded is formed into an arc shape, and is recessed from the center portion toward the edge portion, and the stress is dispersed in the arc shape portion without being concentrated on the edge portion. The one disclosed in Patent Document 1 must process the outflow port into a special shape, and cannot be applied to a bag in which an outflow port is attached, and the related outflow cannot be solved. In the vicinity of the prior art, the present invention is directed to solving the problems of the aforementioned prior art, and the main object is to provide a problem. A bag with an outlet which can concentrate the stress concentrated at the boundary portion of the discharge port sealing portion by a simple structure, and at the same time, can improve the pressure resistance, and the fall impact resistance of 200824977. OBJECTIVE, the present invention is a bag with an outflow port, comprising: a bag body, a bag body formed by laminating a flexible film, 5 and a heat-sealed joint between the ends of the film forming the seam and being sealed. And the outflow port is disposed between the end portions of the film body of the bag body, and is heat-sealed together with the film end portion to be sealed, and a stress dispersing sheet is disposed outside the bag body, and the stress dispersing film is a heat-welding portion that crosses the outflow port and a boundary portion of the film portion that faces the storage space of the bag body and is freely deformable, and is adhered to partially cover the heat-welding portion of the outflow port and Both freely deformable film portions. The stress dispersion sheet is preferably provided so as to cover the intersection of the left and right edge portions of the outflow port and the boundary portion between the heat fusion portion of the outflow port and the film portion. Further, the stress-dispersing sheet preferably has a three-dimensional shape in which the shape of the outlet is formed. Further, the outer peripheral shape of the stress-dissipating sheet adhered to the portion of the freely deformable film portion 15 preferably constitutes a smooth curved shape. An anti-skid mechanism such as an embossed portion or a hole may be provided on the surface of the stress dispersion sheet. Further, a rigid adjustment mechanism for adjusting the rigidity may be provided on the stress dispersion sheet. 20 At this time, the portion of the stress dispersion sheet adhered to the side of the freely deformable film portion is preferably formed such that the rigidity gradually weakens toward the outer periphery. The method of weakening the rigidity may be such that a plurality of slits are provided on the outer peripheral edge of the portion where the stress dispersion sheet is adhered to the side of the film portion, or the thickness may be gradually thinned toward the outer periphery. 7 200824977 In addition, the stress is preferably formed by the same material as the bag body. According to the present invention, even if the internal pressure of the bag body rises due to the thermal shock of the content or the impact at the time of falling, the stress dispersion sheet can be used to disperse the stress and not concentrate on the heat of the outflow port. The boundary between the force valley joint portion and the film portion, particularly the intersection of the left and right edge portions of the outflow port and the boundary portion, can prevent cracking of the film. Further, since a moderately rigid rigidity can be produced by providing the stress dispersing sheet, the automatic clogging of the bag body at the root of the outflow port can be prevented. Further, by the rigidity of the stress dispersion sheet, the stress dispersion sheet can be used as a grip portion in a hand-held bag, and the usability is good. Further, since the stress dispersion sheet is mounted on the outer surface of the bag body, the contents of the stress dispersion sheet are not affected by the contents. The difference is 4匕. It is also possible to achieve the word stress by the form of the stress dispersing sheet, the color of the color and the enamel decoration, and to set the gap to cover the outflow point, thereby effectively preventing the decane pull of the broken portion and the outflow of the film, and the welded portion. At the intersection, the three-dimensional shape of the shape of the mouth can be effectively formed, and if the stress dispersion sheet is patterned to flow out, the adhesion can be easily performed.

該附有流出口之袋包含有：袋本體1，係疊合可撓性薄 膜所成形之袋體，且構成接縫之薄膜端部間熱熔接而被密 10 封者；及流出口3，係裝設在袋本體1之薄膜端部間，且與 薄膜端部一同熱熔接而被密封者。於袋本體1外面設置有作 為應力分散片之應力分散貼片4，且該應力分散貼片4係跨 過作為流出口 3之熱熔接部的流出口密封部2與面向袋本體 1之内部空間且可自由變形的薄膜部5之邊界部6，黏貼成局 15

要是使應力分散之構造即可，舉例言之，如第_圖所示， 亦可於對應於邊緣部3a與邊界部6之交點p的部分設置透孔 5 44 ° 又如第1(C)圖所示，應力分散貼片4包含有仿照流出 3之幵乂狀的立體形狀，圖示例中為仿照流出口 3之基部31 之検截面形狀的半紡錘形狀或半舟形形狀之立體形狀部 4T，且與流出口密封部2密接。 1〇 應力分散貼片4之黏貼可藉由接著劑、黏著劑來黏貼， 又，亦可藉由雙面膠帶來黏貼，且亦可依照材料之不同而 進行熱熔合，總而言之，只要密接於袋本體1之表面而不會 剝離即可。 於圖示例中，應力分散貼片4之外周形狀係藉由一圓弧 15部41與一直線部42所構成而作成圓弧面形狀，然而，黏貼 在薄膜部側之部分的外周形狀只要藉由平滑之曲線來構成 即可，舉例言之，如第1(E)圖所示，亦可為圓弧部41與直 線部42透過左右直線部43、43來連接之形狀，且如第1(F)

再者，由於應力分散貼片4具有適度之剛性因此可將 應力分散貼片4使用來作為用手把持之把持部且持有位置 1〇亦會擴大。若藉由壓紋部加工等於應力分散貼片錄面附上 四凸結構，則可更輕易地具有作為防滑機構之機能。 由於應力分散貼片4係裝設在袋本體丨之外表面因此 <適用於既存所有附有流出口之袋，且不會因應力分散袋2 之材質而對内容物造成影響。 15 又，亦可藉由應力分散貼片4之形式、顏色及裝飾來達 成差異化。 第2(D)、2(E)圖係顯示應力分散貼片之變形例。 於前述實施例中，應力分散貼片4係構成為廣泛地覆蓋 在右上邊密封部14、14與薄膜部5之邊界部6全體而不僅是 2〇流出口 4封部’然而，如第2(D)圖所示，亦可僅覆蓋流出 口 3左右之邊緣部3a、3a與邊界部6之交點ρ附近。 該變形例之應力分散貼片140係略呈τ字形狀，且藉由 自流出口密封部2延伸至左右上邊密封部14、14之端部附近

150之縱向貼片部151與橫向貼片部152來抑制，且應力可分 5散至橫向貼片部152全體，因此可防止薄膜之邊緣旋破。 實施例2 第3圖係顯示有關本發明實施例2之附有流出口之袋。 该附有流出口之袋係收納於高剛性之包裝容器，且藉 由流出口 203與包裝容器207固定，並於收納在包裝容器2〇37 10 内之狀態下將該袋減少容量。 附有流出口之袋包含有：袋本體2〇1，係疊合可撓性薄

Further, the flexibility of the stress dispersion sheet can be easily controlled by a rigidity adjusting mechanism such as slit or hole processing. In particular, the slit is provided on the outer peripheral edge portion of the portion where the stress dispersion sheet is adhered to the side of the film portion, or the thickness is gradually reduced, whereby the stress can be effectively dispersed without impairing the flexibility of the film portion. If the stress dispersion sheet is made of the same material as the bag body, there is no problem to be distinguished when it is discarded.

[Embodiment 3] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on the embodiments shown in the drawings. Embodiment 1 Fig. 1 shows a bag with an outflow port relating to Embodiment 1 of the present invention. The bag with the outflow port includes: a bag body 1 which is a bag body formed by laminating a flexible film, and which is heat-sealed between the ends of the film forming the seam and is densely sealed; and an outflow port 3, It is installed between the film ends of the bag body 1 and is heat-sealed together with the film ends to be sealed. The stress dispersion patch 4 as a stress dispersion sheet is disposed on the outer surface of the bag body 1, and the stress dispersion patch 4 spans the flow outlet sealing portion 2 as the heat fusion portion of the outflow port 3 and the internal space facing the bag body 1. Further, the boundary portion 6 of the freely deformable film portion 5 is adhered to cover the outlet port sealing portion 2 of the outflow port 3 and the freely deformable film portion 5 in a partial manner. In the illustrated example, the bag body 1 is in the form of a so-called edging pouch, and as shown in Fig. 1(C), the bi-fold side film 12, 12 is longitudinally folded by a pair of flat films 11, 11 and left and right sides. Composition. 20 The front edge portions of the double-folded side films 12 and 12 are thermally welded to the left and right side edges of the flat films 11 and 11, and the side seal portions 13 and 13 are formed (see FIGS. 1(A) and 1(B)). The side edges of the flat films 11 and 11 are curved shapes in which the lower portion of the bottom side is curved obliquely toward the inside. On the other hand, the upper edges of the side films 12 and 12 are thermally fused to the upper edges of the flat films 11, 10, 200824977, and the upper sealing portion ι4 is formed (the upper outlet 3 and the left and right upper sealing portions 14 and 14 are formed: (A) Fig.) The center portion of the upper side edge is thermally welded to form the outflow port sealing portion 2, and the sealing portion 2 is connected to the left and right upper side sealing portions 14 and 14. L is thermally welded and the flat film 11 is formed to form the bottom seal portion 15. The film material constituting the bag body 1 is not particularly limited. However, when the film does not contain the structure of the (four) layer, the film is likely to be generated, and the film material is not contained in the film. Preferably, as shown in the first (A) and (B) diagrams, the outflow port 3 includes a base portion 31 having a boat shape or a spindle shape in cross section, and a tube protruding upward from the base portion 31. 32, and the discharge cylinder 32 is blocked by the cap 33. / 戈 罘 15 15 15 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 戈 且 且 且 且 且 且 且 且 且Gradually thinning, and the film end portion of the outflow port sealing portion 2 is shaped like a cross section of the base portion 3 to form a boat or a bell shape 0 as shown in Fig. 1(A), and the stress dispersion patch 4 is It is constituted by a small piece of a plastic piece 2 having an arcuate surface shape surrounded by a circular arc portion "and a linear portion 42 connecting the both ends of the circular arc portion 41. The length of the straight portion 42 is not only the outflow port sealing portion 2 but The length of the bag body 1 is substantially full width until the end edges of the left and right upper sealing portions 14 and 14 are formed, and the arc portion 41 side passes over the outlet port sealing portion 2 and the upper edge portion, the sealing portion 14 and the freely deformable film portion. The boundary portion 6 of the fifth portion protrudes toward the side of the thin film portion 5 by a predetermined size, and includes the intersection point % and % of the left and right edge portions of the outflow port 3 and the intersection point p of the boundary portion 6 of the inner edge portion of the flow opening portion 12 200824977 The vicinity of the boundary portion 6 between the outflow sealing portion 2 and the upper sealing portion 14. However, as long as the stress is divided For example, as shown in FIG. 1 , a through hole 5 44 ° may be provided in a portion corresponding to the intersection p of the edge portion 3 a and the boundary portion 6 as shown in FIG. 1(C). The stress-distributing patch 4 includes a three-dimensional shape that resembles a weir shape of the outflow 3, and in the illustrated example, a three-dimensional shape portion 4T of a semi-spindle shape or a semi-sick shape that resembles the cross-sectional shape of the base portion 31 of the outflow port 3, and The flow outlet sealing portion 2 is in close contact with each other. The adhesion of the stress relief patch 4 can be adhered by an adhesive or an adhesive, or can be adhered by a double-sided tape, and can be thermally fused according to the material. In short, as long as it is in close contact with the surface of the bag body 1 without peeling off. In the illustrated example, the outer peripheral shape of the stress dispersion patch 4 is formed by a circular arc portion 41 and a straight line portion 42. However, the outer peripheral shape of the portion adhered to the side of the film portion may be formed by a smooth curve. For example, as shown in FIG. 1(E), the arc portion 41 and the straight line may be used. The portion 42 is connected to the shape by the right and left straight portions 43, 43 and is as the first ( F) As shown in the figure, the thin film portion side straight portion 20 45 parallel to the straight portion 42 may be formed instead of the circular arc portion, and the left and right straight portions 43 and 43 and the corner portion of the thin film portion side straight portion 45 may be rounded. The rounded corner shape of the circular arc portion 46 is formed, and various other shapes can also be used. For example, the material of the stress dispersion patch 4 can be applied to various plastic materials such as polypropylene and polyethylene, and can also be used as a laminated composite material. The laminated body structure 12 200824977 is not limited to a plastic material, and any material having a dispersible stress can be made of various materials such as paper, rubber, metal, wood, cloth, etc. However, the right side is used and used in the bag body. The materials of the same material and the material of the outflow port 3 are not distinguished when they are discarded, and are excellent in waste. The thickness of the stress-dispersing patch 4 can be appropriately set in consideration of the material, the size, and the like as long as the thickness is moderately rigid. When the thickness is too large, the stress is concentrated on the stress-dispersing patch and the thin film portion side. If the result of the circumference of the P is too thin, the effect of stress dispersion will be reduced. In the case of various inspections, the bag capacity is 100ml and the material of the patch is plastic 10 glue. . Further, as shown in Fig. 2(A), if the plurality of cavities 47 as the rigidity adjusting mechanism are formed on the stress dispersing patch 4, the flexibility of the stress dispersing patch 4 can be easily controlled, and at the same time, it is also possessed. Anti-slip effect. According to the bag with the outflow port according to the foregoing embodiment, even if the internal pressure of the bag body is increased due to the thermal expansion or the impact of the falling of the contents, the bag body 1 is inflated, and the stress can be dispersed. The sheet 4 suppresses deformation of the film portion 5 around the intersection P of the left and right edge portions 3a and 3a of the discharge port 3 of the bag body 1 and the boundary portion 6 of the outlet portion seal portion 2, and the stress is not concentrated on the right and left edges. The intersection point P of the portions 3a, 3a and the boundary portion 6 can prevent the periphery of the intersection point p from being deposited from the edge of the boundary portion 6. Further, since the outer peripheral shape of the portion of the stress-dispersing patch 4 that protrudes toward the thin film portion 5 is a smooth curved shape of the non-corner portion by the circular arc portion 41, no stress is concentrated on the outer periphery of the stress-distributing patch 4 Hey. In order to prevent the stress from being concentrated on the arc portion 41 on the outer periphery of the film portion side adhesion portion of the stress 77, the plurality of layers 13 200824977 may be provided as shown in the second (B) diagram. The slit 48 attenuates the rigidity, or the structure is gradually thinned as shown in Fig. 2(C) to weaken the rigidity. Further, since the stress-dispersing patch 4 can be provided to generate an appropriate rigidity, the inner portion (four) can be made even if the content is injected, and the thin film portion 5 can be held by stress dispersion, and the flow can be prevented. The automatic blocking of the bag body 1 at the outlet root is not required to prevent the automatic blocking tool 0. In addition, since the stress dispersion patch 4 has moderate rigidity, the stress dispersion patch 4 can be used as a handle for hand control. The position of the department will also be expanded. If the embossing portion is processed to be equal to the stress-distributing patch recording surface and the four-convex structure is attached, it is easier to function as a non-slip mechanism. Since the stress dispersion patch 4 is attached to the outer surface of the bag body, it is suitable for all existing bags having the outflow port, and does not affect the contents due to the material of the stress dispersion bag 2. 15 Also, the differentiation can be achieved by the form, color and decoration of the stress dispersion patch 4. The second (D) and (E) drawings show a modification of the stress dispersion patch. In the foregoing embodiment, the stress-distributing patch 4 is configured to cover the entire boundary portion 6 of the upper right side seal portions 14 and 14 and the thin film portion 5, and is not only the 2 〇 flow outlet 4 seal portion. However, as the second As shown in the diagram (D), it is also possible to cover only the vicinity of the intersection ρ of the edge portions 3a and 3a of the left and right of the outflow port 3 and the boundary portion 6. The stress-distributing patch 140 of this modification is slightly τ-shaped, and extends from the outflow port sealing portion 2 to the lateral patch portion 141 near the end portions of the left and right upper side sealing portions 14, 14 and the width corresponding to the outflow port seal In the center of the section, the vertical 14 200824977 is composed of the patch unit 142. The longitudinal patch portion 142 extends over the boundary α Ρ 6 of the outflow port sealing portion 2 toward the freely deformable film portion by a predetermined size, and the lower (four) side of the lateral patch portion 141 is sealed along the outflow port sealing portion 2 and the left and right upper edges 414. The lower side edges extend, and the left and right side edges of the longitudinal patch portion 142 form an arc shape of the concave shape 5. The round fox shape portion 143 is formed by a substantially quarter arc, and has a smooth curved shape in which one end is located at a corner portion of the longitudinal patch portion 142 and the other end is connected to a lower side edge of the lateral patch portion 141. Further, the corner portion of the longitudinal patch portion 142 should also be rounded. The arc-shaped portion 143 covers the periphery of the intersection point 3 between the left and right edge portions 3a, 10 3 & and the boundary portion 6. Accordingly, when the bag body 1 expands due to an increase in the internal pressure, deformation of the film portion in the vicinity of the boundary portion 6 of the outflow port sealing portion 2 can be suppressed by the longitudinal projection portion 142 of the stress dispersion patch 140, and the stress can be along The arc-shaped portion 143 is owed for a few months, so that the edge of the film can be prevented from being broken. 15(E) is a view in which the stress dispersion patch 150 is formed in a slightly inverted T shape and includes a longitudinal patch portion 151 extending in the longitudinal direction and a lateral direction extending from the lower end portion of the longitudinal patch portion 151 toward the left and right. Patch unit 152. The longitudinal patch portion 151 extends from the boundary portion 6 of the outflow port sealing portion 2 toward the thin film portion 5 by a predetermined width in substantially the same width as the outflow port 3, and the lateral patch portion 152 includes the outer circumference 20 rounded portion 152a and The left and right ends of the outer circumferential arc portion 152a are inclined portions 152b that extend obliquely toward the left and right side edges of the longitudinal patch portion 151. The left and right end portions of the lateral patch portion 152 are located outside the right and left edge portions 3a, 3a of the outflow port 3 with respect to the center line of the outflow port 3, and the intersection of the left and right edge portions 3a, 3a of the outflow port 3 and the boundary portion 6 The p surrounds the three sides by the lateral patch portion 152, the longitudinal patch portion 151, and the upper 15 200824977 side seal portion. Accordingly, even if the bag body 1 expands due to an increase in the internal pressure, the deformation of the film portion 5 flowing out of the boundary portion 6 of the σ seal portion 2 can be deformed by the longitudinal patch portion 151 and the lateral patch portion of the stress dispersion patch 150. 152 is suppressed, and the stress can be divided into 5 to the entire lateral patch portion 152, so that the edge of the film can be prevented from being broken. Embodiment 2 Fig. 3 shows a bag with an outflow port relating to Embodiment 2 of the present invention. The bag with the outflow port is housed in a highly rigid packaging container, and is fixed to the packaging container 207 by the outflow port 203, and the bag is reduced in capacity while being housed in the packaging container 2〇37 10 . The bag with the outflow port includes: a bag body 2〇1, which is a bag body formed by laminating a flexible film, and is formed by heat-sealing between the ends of the film forming the seam; and the outflow port 203 is It is installed between the end portions of the film of the bag body 2〇1, and is heat-sealed together with the film end to be sealed. The bag body 201 is formed by a side pocket, that is, a flat film is bent to form a pair of front and rear flat films 211 and 211 and a pair of side film 212 which are folded between the side edges of the flat films 2U and 211, 212. The side seal portion 213 is used to seal both end portions of the flat film in the bending direction to form a cylindrical body, and is folded into the side film 212, 212 by a pair of end seal portions 2 21 ^ 215, 215 to package the two ends, and the bag body 201 is used in the shape of the expanded rectangular body. In other words, the shape of the expanded rectangular body is such that a pair of front and rear side portions A, Α, a pair of right and left end faces Β, Β, and an upper face (the hexahedron with the bottom portion D) are formed in a state in which the outflow port 203 is upward. The side surface portion A, the cymbal portion, the end surface portion Β, and the cymbal system 16 200824977 are formed by bending the flat films 211 and 211 constituting the bag body 201, and the upper surface portion C and the bottom surface portion D are formed by the side film portions 212 and 212. The end seal portion 215 extends in the vertical direction at the center of the end surface portions B, b, and the side seal portion 213 extends along the upper edge of the side surface portion a of one side to the left and right ends, and then turns into the end face portion B. And the upper edge of B extends to the end seal portion 215 located at the center of the upper edge of the end faces B and B. When the capacity is reduced, the end faces B, B, the upper face c, and the bottom face are folded inside, The interval between the side portions A and A is contracted in the direction of reduction in parallel with each other. 10 The side seal portion 213 is disposed along the corner line of the corner film 211, 211 and the side film 212, 212, and the flow port 2 〇 3 The side seal portion 213 is thermally welded and constitutes the outflow port sealing portion 2〇2, that is, the outflow port 2〇3 is inserted The upper side edge of the face A is biased to the side of the side surface B side of the flat film 211 and the film end of the side film 212, and is thermally welded simultaneously with the film to form an outflow port 15 sealing portion 202. Further, the outflow sealing portion The 202 series is connected to the side seal portion 213. As shown in Fig. 3(C), the base portion 231 of the outflow port 2〇3 for heat fusion is formed in a boat shape or a spindle shape, and the discharge cylinder 232 is directed from the base portion 231 toward The outflow port sealing portion 202 also forms a boat shape or a spindle shape in accordance with the cross-sectional shape of the base portion 231 of the outflow port 203. 20 The stress dispersing patch 204 is adhered to the outside of the side surface portion A on which the outflow port 203 is attached, and In the same manner as in the first embodiment, the stress-dispersing patch 204 is adhered to the boundary portion 2〇6 of the film portion 205 which is freely deformable across the inner space of the outlet port Φ sealing portion 202 and the inner surface of the bag body 2〇1, and is adhered to partially cover. Both the outflow sealing portion 202 and the freely deformable thin film portion 205. 17 200824977

The mouth seal portion 202 is unfolded in the bag, and since the outflow port 203 is attached to one end of the side seal portion 213, the plane shape of the stress dispersion patch 204 is formed by the arc portions 241 of the four semicircular arc shapes. The laterally extending straight portion 242 and the fan-shaped portion of the straight line #243 extending in the longitudinal direction 243 and the lateral straight portion 242 are attached to the side of the arcuate portion 241 of the outflow sealing portion 202 and the side sealing portion 213' are adhered to Freely deformable film portion 5. Further, the longitudinal straight portion 243 is disposed along the side edge of the side surface portion a. The stress-dispersing patch 204 also suppresses the bag body 2〇 by the stress dispersion patch 204 even if the internal pressure of the bag body 201 rises due to the thermal expansion or fall of the contents, and the bag body 2〇 is expanded. Deformation of the film portion 2〇5 around the intersection P of the edge portion 203a, 203& and the outlet port sealing portion 202 and the boundary 4206 of the film portion 205, and the stress is not concentrated on the left and right edge portions 203a, The intersection P of 203a and the boundary portion 206 can prevent the edge from being broken. Further, since the outer peripheral shape of the adhesive portion of the stress-dispersing patch 204 on the side of the film portion 205 constitutes the smooth circular arc portion 241 having no corner portion, no stress is concentrated on the outer circumference of the stress-distributing patch 204. As shown in the second (B) and (c) diagrams, in order to prevent the stress from being concentrated on the circular arc portion 24 adhered to the thin film portion 205, the stress dispersing sheet 2〇4 is preferably provided with a slit or gradually toward the outer periphery. Thinning and weakening rigidity. 18 200824977 Moreover, since the stress dispersion patch 204 can be provided to generate moderate rigidity, the side portion A can be held even when the folding is caused by the reduction in capacity, and the bag body 2 at the root of the outflow port can be prevented. 1 is automatically blocked, so there is no need to prevent the automatic blocking tool used in the past. Since the stress dispersion patch 204 is mounted on the outer surface of the bag body 201, the content of the stress dispersion bag 2 is not affected by the material of the stress dispersion bag 2, and the form and color of the stress dispersion patch 204 can also be The modification of the decoration to achieve the differentiated 0 stress dispersion patch is the same as that of the first embodiment. In addition, in the foregoing embodiments, the structure of the bag body indicates that the form of the pocket bag is 'but' not limited to the edge pocket, and may also be a flat structure of three bags, a square bag, etc., and is also applicable to The self-standing stand-up pouch construction is not limited to the bag construction.
