Description

  The present invention relates to a cylindrical pouch with a spout, in which a spout that is easy to open is fixed, and more specifically, a shape-retaining member is attached after filling the contents, or the cylindrical body portion has an internal pressure within a predetermined range. The present invention relates to a cylindrical pouch with a spout having excellent shape retention and easy opening.

  Conventionally, as shown in FIG. 18, a pouch with a spout (50) provided with folding sheets (70) on the left and right sides of two trunk sheets (60) is known, and since it has excellent flexibility, Due to its excellent extrudability and, unlike can containers and PET bottles, it is excellent in volume reduction after use and is easy to carry. Thus, the pouch formed by inserting the folding sheet (70) into the side portion inserts the folding sheets (70) on the left and right of the trunk sheet (60) having the shape shown in FIG. 19, for example, and the trunk sheet (60). And the folded sheet (70) are side-sealed (80) into a predetermined shape to produce a bag. The top surface portion is constituted by the upper end portion of the trunk sheet (60), and the bottom surface portion is constituted by the lower end portion. As shown in FIG. 18, the side portion of the pouch after filling the contents is substantially rectangular.

  However, in general, can containers and plastic bottles that sell fluid food such as beverages have a cylindrical shape, whereas a cylindrical gusset pouch does not exist and lacks design. Furthermore, while cylindrical containers can be sold with vending machines, gusset pouches are difficult to sell with vending machines that handle cylindrical containers such as plastic bottles because of their shape. It is limited to store display.

  On the other hand, when a soft film is formed into a cylindrical shape and a circular top surface portion and bottom surface portion are bonded, a cylindrical pouch can be manufactured, but it cannot be folded before and after filling the contents, and reduced after use. It is difficult to make.

  On the other hand, a folding sheet for the top and bottom portions is inserted above and below the two body sheets, sealed with a predetermined curve, and both ends of the two body sheets are side-sealed to form a body part. As the contents are filled, the folded sheet of the bottom surface portion spreads as the contents are filled, and a pouch container having a cylindrical body portion can be obtained. However, since the barrel portion becomes cylindrical as the contents are filled, depending on the amount of filling, the barrel portion may not be formed into a cylindrical shape. In addition, if a spout with a cap screwed on the top surface is attached, the contents can be easily taken in and out, and leakage of the contents can be prevented by the cap. It may be kinked and difficult to open. On the other hand, if the filling amount is increased, it is easy to maintain the cylindrical shape, but if the body is gripped at the time of opening, the contents may flow out and it may be difficult to open the plug.

  In addition, the soft film may be inferior in mechanical strength, particularly when wrinkles or sagging are formed on the pouch, which is not preferable in appearance, and vibration and other forces during transportation are concentrated on the wrinkles. This will cause damage to the container.

  In view of the above situation, the present invention can be folded before filling the contents, the barrel can be formed into a cylindrical shape regardless of the filling amount of the contents, and can be easily opened and has an excellent appearance. An object is to provide a cylindrical pouch with an outlet.

  As a result of examining the cylindrical pouch with a spout in detail, the present inventors can adjust the internal pressure to a predetermined range after filling the contents, and the body can be formed into a cylindrical shape regardless of the filling amount of the contents. It can be easily gripped when the internal pressure is within the specified range, can be prevented from twisting at the time of opening, and can improve the opening performance. If the shape of the top and bottom surfaces to be secured is secured, the design is excellent, and even when the content is filled, the content can be prevented from flowing out when the cap is opened. The present invention has been completed by finding that the design of the entire cylindrical pouch with a spout can be improved by adding color and character information to these.

That is, according to the present invention, a top surface portion and a bottom surface portion are formed by folding sheets heat-sealed on the top and bottom of two body sheets, and both ends of the two body sheets are side-sealed to form a cylindrical body portion.

Hereinafter, a cylindrical pouch with a spout of the present invention will be described in detail with reference to the drawings.

(1) Cylindrical pouch with spout The “cylindrical pouch with spout” according to the present invention is obtained by filling a predetermined “cylindrical pouch container with spout”.

  The cylindrical pouch container with a spout targeted in the present invention has a top surface portion and a bottom surface portion formed by folding sheets that are heat-sealed on the top and bottom of the two body sheets. A cylindrical pouch container with a spout, in which both ends are side-sealed to form a body portion, and a spout is fixed to the top surface portion. As the contents are filled from the spout, the bottom surface and the top surface expand, and the body portion has a cylindrical shape with a substantially radius R, but before filling the contents, the top surface and the bottom surface are folded in two. It can be folded flat by the folding sheet, and similarly, after the contents are extracted, it can be folded flat via the folding sheets on the top surface portion and the bottom surface portion.

  An example of a suitable aspect of such a cylindrical pouch with a spout or the pouch container is shown in FIG. Fig.1 (a) is an external appearance perspective view of the cylindrical pouch with a spout which filled the contents into the cylindrical pouch container with a spout, FIG.1 (b) is the top view. In FIG. 1 (a), folding sheets (70) are inserted above and below the two body sheets (60) and sealed with a predetermined top surface seal line (73) and bottom surface seal line (75), A top surface portion and a bottom surface portion are formed together with the folding sheet (70), and both ends of the body sheet (60) are side-sealed (80) to form a cylindrical body portion, and a spout (50) is fixed to the top surface portion. The provided aspect is shown. In order to seal the both ends of the two body part sheets (60), the body part after filling the contents has a cylindrical shape. On the other hand, in order to make a pouch container (100) so that the trunk portion has a cylindrical shape over the entire length of the pouch trunk portion, the top surface seal composed of the folding sheet (70) and the trunk sheet (60). The line (73) and the bottom seal line (75) may be heat-sealed with an R curve or other seal line. In FIG. 1A, the coarse dots indicate the heat-sealed portion between the folding sheet (70) and the trunk portion sheet (60), and the fine dots indicate the thermal fusion portion between the trunk portion sheets (60). .

  In the cylindrical pouch with a spout shown in FIG. 1, a spout (50) is fixed between the folding sheet (70) on the top surface and the body sheet (60), as shown in FIG. 1 (b). Therefore, the spout (50) is unevenly distributed on the side portion of the top surface portion. However, the cylindrical pouch with a spout of the present invention is not limited to the above. For example, the spout is fixed in the center of the folding sheet that forms the top surface portion in advance, and the spout is fixed in the center of the top surface portion. It may be a thing. The shape of the spout used is not particularly limited.

The cylindrical pouch with a spout of the present invention can be used by filling a beverage or a jelly-like product as the contents.
(2) Internal pressure adjustment The cylindrical pouch with a spout of the present invention is filled with the contents from the spout of the pouch, and the internal pressure inside the pouch when initially opened is 0.01 to 5 kgf / cm at a temperature of 25 ° C. ² , more preferably 0.1 to 1 kgf / cm ² .

  The cylindrical pouch with a spout of the present invention has a folded body that forms a bottom surface as the contents are filled into the cylindrical pouch container with a spout, and the cylindrical body portion has a cylindrical shape. On the other hand, when the filling amount of the content is small, the folded sheet is not widened, the body part is not formed into a cylindrical shape, and the appearance is not excellent, and a cap that is gripped and screwed into the spout is attached. When opening the cap, the cylindrical body may rotate and twist as the cap rotates, making it difficult to open or open the cap.

However, when the internal pressure is adjusted to the above range, the barrel can be secured in a cylindrical shape regardless of the filling amount of the contents, and can be easily opened or opened by gripping the cylindrical barrel. If the internal pressure at the time of opening is less than 0.01 kgf / cm ² , the cylindrical shape retention is not sufficient. On the other hand, if it exceeds 5 kgf / cm ² , a spout is provided even by a slight impact due to excessive internal pressure. The cylindrical pouch may be damaged.

In order to adjust the internal pressure to the above, for example, liquid nitrogen or liquid carbon may be dropped after filling the contents. More specifically, when a cylindrical pouch with a spout contains 200 ml of contents, and the cap is screwed and sealed in 5 seconds after filling the contents, 0.05 to 1.0 ml of liquid nitrogen, More preferably, 0.1 to 0.3 ml is dropped. In the case of liquid carbonic acid, 1.0 to 20 ml, more preferably 0.1 to 0.3 ml is dropped. When the sealing time by screwing the cap exceeds 5 seconds, liquid nitrogen or liquid carbon dioxide may be further increased. According to the above, the internal pressure at the time of opening can be adjusted to 0.01 to 5 kgf / cm ² .

(3) Mounting of the shape retaining member In the present invention, after filling the cylindrical pouch with the spout, the shape retaining member is mounted on the top surface portion and / or the bottom surface portion to maintain the shape of the cylindrical body portion. Can do. The cylindrical pouch with a spout of the present invention changes its shape depending on the filling amount and remaining amount of the contents, so even if the shape retention is ensured by adjusting the internal pressure, after opening one end It may be difficult to maintain shape retention. However, the body can be held in a cylindrical shape by mounting the shape-retaining member regardless of the filling amount or remaining amount of the contents. Accordingly, such a cylindrical pouch with a spout may be one in which the internal pressure is adjusted. When the internal pressure is adjusted to the above range, the contents may blow out from the spout at the time of opening depending on the amount of the contents filled. However, by attaching the shape-retaining member, direct gripping on the cylindrical body can be avoided. Can be prevented.

  As the shape-retaining member, those that can be mounted on the top and / or bottom of the spouted cylindrical pouch and can retain the shape of the top and bottom can be widely used.

  As such a shape-retaining member, there is a substantially circular body-like material fitted to the inner periphery of the top surface portion and / or the bottom surface portion. A plan view of such a mental object is shown in FIG. FIG. 2 (a) shows a substantially circular mental object for the bottom surface, and FIG. 2 (b) shows a case where the vicinity of the side seal is further cut off. Since the trunk portion is substantially circular, the circular shape of the bottom surface portion and the top surface portion can be maintained by inserting a substantially circular body-like object. Moreover, if both ends of a circular menco-shaped object are cut off, it can be easily mounted on the bottom surface or the top surface.

  The shape retaining member in the form of a mental shape may be mounted as it is on the bottom surface or top surface of the cylindrical pouch with spout, but an adhesive or an adhesive may be used when mounting. If the meniscus is removed after use of the cylindrical pouch with the spout, the pouch can be folded to reduce the volume, and the pouch and the menco can be recycled separately.

  Furthermore, as a shape-retaining member used in the present invention, as shown in FIG. 3, an insertion piece (110a) may be formed at both ends of the above-mentioned men-shaped object. FIG. 3 (a) is a perspective view of a body-like material having insertion pieces (110a) at both ends, and FIG. 3 (b) is a plan view before folding the insertion piece (110a), FIG. 3 (c). FIG. 3D is a side view of the subsequent plan view. As shown in FIG. 1 (a), the bottom surface of the cylindrical pouch with a spout to which the shape retaining member is attached according to the present invention is such that the bottom line seal line (75) faces the side seal (80) from the center of the bottom surface. Therefore, a space is formed in the vicinity of the intersection of the bottom seal line (75) and the side seal (80). If the insertion piece (110a) is inserted into this space, it is possible to stably attach the mental object to the bottom surface without using an adhesive or an adhesive. Similarly, a space is formed in the vicinity of the side seal (80) portion on the top surface portion, so that a mental object can be inserted. FIG. 4 (a) shows a bottom view in which the mental article (110) shown in FIG. 3 is mounted on the bottom of the cylindrical pouch with spout shown in FIG.

  The cylindrical pouch with a spout of the present invention has a spout (50) fixed on the top surface portion. If the fixed portion of the spout (50) is cut off, It is possible to wear a shape. FIG. 4B shows a plan view of a cylindrical pouch with a spout in which a shape-retaining material-like shape retaining member is mounted on the top surface of the cylindrical pouch with a spout shown in FIG. In FIG. 1, since the spout (50) is unevenly distributed to the side of the top surface, the menco-like object has a shape in which the shape of the fixed portion of the spout (50) is cut out from a substantially circular shape. Thereby, the spout (50) is protruded upward from the mental object, and the shape-retaining member is excellent in the shape retaining property of the cylindrical body and excellent in the unsealing property.

  The size of the Menco-like object only needs to fit on the inner peripheral side of the top and bottom of the cylindrical pouch container with spout, and corresponds to the size of the top and bottom of the cylindrical pouch with spout and the shape of the mental And may be selected as appropriate. The shape of the insertion piece (110a) is also not particularly limited, and can be appropriately selected according to the shape of the cylindrical pouch container with the spout.

  Furthermore, the shape-retaining member that can be used in the present invention may be a lid-like material that covers the outer periphery of the top surface portion or the bottom surface portion in addition to the mental material. Such a lid is shown in FIG. The lid-like object (120) shown in FIG. 5 is formed substantially vertically on the lid plate portion (120a) covering the top surface portion and the lid plate portion (120a), and the outer periphery of the lid plate portion (120a). The cover plate part (120b) is formed with a hole part (120c) that penetrates the spout. FIG. 6 shows an aspect in which the lid (120) shown in FIG. 5 is attached to the top surface portion of the cylindrical pouch with spout shown in FIG. The spout (50) protrudes from above the lid (120) and can be opened easily. In addition, when covering the outer periphery of a bottom face part, it becomes a bottle-like object, but only a mounting part differs, and this is also called a lid-like object for convenience.

  The size of the lid is only required to cover the outer peripheral side of the top and bottom surfaces of the cylindrical pouch container with spout, and can be selected appropriately according to the size and shape of the top and bottom of the cylindrical pouch with spout. Good. The shape of the hole (120c) is not particularly limited, and can be appropriately selected according to the shape of the spout (50).

  The top surface portion and the bottom surface portion to which the lid-like object is attached can be gripped via the lid-like object, and an internal pressure is not applied to the cylindrical body during gripping. The cylindrical pouch with a spout of the present invention has a side seal formed on the cylindrical body, and may contact the palm when gripping the cylindrical body. Contact to the seal can be avoided.

  The lid attached in this way is easy to remove, and if the lid is removed after using the pouch, the pouch can be folded to reduce the volume, and the pouch and lid can be recycled separately. can do.

  The shape-retaining member such as a mental object or a lid that can be used in the present invention can be formed of paper, plastic, metal or the like. These can be colored and the design can be improved by the color of the color pattern. In addition, the contents of the product, the date of manufacture, the expiration date, and other information can be added by characters.

(4) Cylindrical pouch container with spout The cylindrical pouch container with spout used in the present invention is folded in two along the folding line (70c) above and below the two body sheets (60) as shown in FIG. The folded sheet (70) is inserted to form a top surface portion and a bottom surface portion, and both ends of the two body sheet (60) are side-sealed (80) to form a cylindrical body portion. A spout (50) is fixed to the top surface portion of the pouch container body. In FIG. 7, although the spout (50) shows the aspect fixedly provided between a trunk | drum sheet | seat (60) and a folding sheet (70), a spout (50) and a folding sheet are shown by the seal line (70a). (70) and a trunk | drum sheet | seat (60) are adhere | attached, and a trunk | drum sheet | seat (60) and a folding sheet | seat (70) are adhere | attached by a seal line (70b). Therefore, the top surface seal line is composed of a seal line (70a) and a seal line (70b), and the bottom surface seal line is composed of two seal lines (70b) separated by a folding line (70c). Is done.

  In FIG. 7, although the folding line (70c) is formed in the approximate center of the folding sheet (70), the position of the folding line (70c) is not limited to the center. For example, the folding sheet (70) and the body sheet (60) at the bottom may be heat-sealed with an asymmetric line at the folding line (70c). The same applies to the top surface. However, if the fold line (70c) is in the center of the fold sheet (70), the top and bottom surfaces can be made to the left and right, making it easy to fit the above-mentioned body-like object and to attach the lid-like object. Can be done.

  Moreover, there is no limitation in particular as a seal line (70b) of a pouch container main body, For example, R curve etc. can be illustrated. On the other hand, when the distance from the folding line (70c) of the folding part sheet (70) to the farthest seal portion is A, it is preferable to form the curve with ASinθ. Thereby, a cylindrical shape is securable over the full length of the trunk | drum by a trunk | drum sheet | seat (60).

  In addition, when fixing the spout (50) on the top surface portion, except for the fixed portion of the spout (50), it is formed by an R curve or an ASinθ curve in the same manner as the seal line (70b). For the fixed part of the outlet (50), a seal line may be selected according to the shape of the spout (50). For example, when a spout (50) having a boat-shaped adhesive portion (20) in a plan view is fixed to the lower portion of the hollow cylindrical portion (30) as shown in FIG. ) And the folded sheet (70) may be bonded and fixed to the bonding portion (20). In addition, if the curve of the boat shape of the adhesion part (20) is the same as the curve of the top surface part, it is suitable for ensuring the cylindrical shape of the trunk part. In particular, in the bonding part (20), it is preferable that the curve on the side to be bonded to the body sheet (60) is the same as the curve on the inner periphery of the top surface part.

  On the other hand, the spout that is fixed to the substantially circular top surface portion may be a spout that can be fixed to the side of the top surface portion as shown in FIG. FIG. 9 is an external perspective view of an example of such a spout, and a plan view (a), a left side view (b), a front view (c), a right side view (d), and a bottom view of the spout ( FIG. 10 shows e). Although not shown in FIGS. 9 and 10, a lid that can be screwed through the spiral (31) is provided.

  As shown in FIG. 9, the spout (50) includes a cylindrical pour-out portion (A) composed of a hollow tubular portion (30) and a hollow adhesive base portion (B) connected to the tubular pour-out portion. And a bottom portion composed of a hollow portion (10) formed substantially at the center, a forming line (I) and a forming line (II) forming the outer periphery of the hollow portion, and the bottom surface And an adhesive part (20) extending vertically from the part. The formation line (I) is a curve having a radius R as shown in FIG. Thereby, it can mount | wear to a top | upper surface part along the cylindrical shape of a trunk | drum. The forming line (II) is asymmetric with the forming line (I) with respect to a line connecting two intersections of the forming line (I) and the forming line (II), and the forming line (II) And the formation line (I) have the same length. Thereby, it can seal without producing a wrinkle and sagging in the folding part sheet | seat which comprises a pouch upper end. In addition, there is no restriction | limiting in particular in the length of formation line (I), Although it can select suitably by a use, Preferably it is 30-100 mm, More preferably, it is 35-80 mm. If it is less than 30 mm, it may be difficult to hold it in the palm through the spout, while if it exceeds 100 mm, the weight increases, which is disadvantageous.

  The formation line (II) preferably has a straight line (IIa) at a part thereof. Thereby, if strength can be given to a container and it is a straight line, a spout can be shape | molded more thinly, and it can fold before content filling and after use, and can be reduced in capacity. The straight line (IIa) is preferably parallel to a line (L1) connecting two intersections (P1, P2) of the formation line (I) and the formation line (II). FIG. 10E shows a straight line (IIa) of the formation line (II) parallel to the line (L1) connecting the two intersections (P1, P2) of the formation line (I) and the formation line (II). Show. The straight line (IIa) is 0.05 to 0.8 times, more preferably 0.1 to 0.6 times, and particularly preferably 0.2 to 0.5 times the forming line (II). This is because, within this range, a sufficient hollow (10) can be secured and a seal line can be easily formed to effectively prevent wrinkles and sagging.

  Further, as shown in FIGS. 11 (a) and 11 (b), both end portions of the straight line (IIa) constituting the forming line (II) and two of the forming line (I) and the forming line (II) are formed. The two intersection points (P1, P2) are respectively connected by a forming line (IIb), and an angle (θ1) formed by the straight line (IIa) and the forming line (IIb) is 10 to 90 °, more preferably 10 to 10 °. 60 °, particularly preferably 10 to 45. FIG. 11A shows the case where the formation line (IIb) includes a straight line, and FIG. 11B shows the case where all the formation lines (IIb) are curves. As shown in FIG. 11A, when the formation line (IIb) includes a straight line (IIb ′), an angle formed by the straight line (IIa) and the straight line (IIb ′) included in the formation line (IIb) ( θ1) is 10 to 60 °. At this time, the straight line (IIa) and the forming line (IIb) are preferably formed with corners that intersect with a radius R of 2 mm or more, more preferably 2 to 100 mm, and particularly preferably 4 to 80 mm. . In particular, when the container is required to have strength, by forming roundness at the corner, physical impact on the corner after bag making can be avoided and leakage of contents can be prevented.

  On the other hand, as shown in FIG. 11B, when the formation line (IIb) is a curve, a tangent at the inflection point in the formation line (IIb) connecting the end of the formation line (IIa) and the intersection point; An angle (θ1) formed by a line (L1) connecting two intersection points (P1, P2) of the formation line (I) and the formation line (II) is 10 to 60 °. In FIG. 11B, a tangent at the inflection point is indicated by L2. This is because if the angle (θ1) formed by the straight line (IIa) and the forming line (IIb) is in the above range, wrinkles and sagging can be efficiently prevented when the seal line (70a) is formed. When there are a large number of bending points, the angle formed with the tangent at the bending point closest to the straight line (IIa) is used.

  In addition, the bonding portion (20) has a bonding portion width formed by the forming line (I) and the forming line (II) as d, and a bonding depth from the upper end of the bonding base as a. It is preferable to have an adhesion portion length equal to or greater than the adhesion depth (a) based on the following formula (1) when viewed from the front.

FIG. 12 is a view for explaining the longitudinal section of the folded sheet constituting the top surface portion when the spout is fixed to the top surface portion of the pouch container with a seal line having a predetermined shape. As shown in FIG. 12, when the spout having the bonding part width (d) and the bonding depth (a) is fixed to the folding sheet constituting the top surface part by the seal line shown in the above formula (1). The shape of the folded sheet after filling the contents is sealed by forming a slope indicated by a straight line b from the substantially central part of the pouch toward the spout, as viewed from the central longitudinal section of the pouch.

  On the other hand, the bonding part (20) has a bonding part width constituted by the forming line (I) and the forming line (II) of the spout as d, and a bonding depth from the upper end of the folding part as a. In addition, from the upper end of the bonding portion, the bonding portion length may be equal to or greater than the bonding depth (a) based on the following formula (2) when viewed from the front.

図１３は、別態様のシールラインで注出口を折込シートに固設した際の折込シートの縦断を説明する図である。内容物充填後の天面部の形状は、パウチ中央縦断面視、パウチの端部から注出口に向かって直線ｂで示す傾斜を構成する。

FIG. 13 is a view for explaining a longitudinal section of the folded sheet when the spout is fixed to the folded sheet with another seal line. The shape of the top surface after filling the contents constitutes a slope indicated by a straight line b from the end of the pouch toward the spout, as viewed from the center vertical section of the pouch.

  In this way, the spout can be formed into a cylindrical shape by fixing it to the top surface portion with a seal line having a predetermined shape, and the top surface portion is, for example, as shown in FIG. 12 or FIG. Different shapes can be formed. In order to fix with a predetermined seal line corresponding to the shape of the top surface portion, the adhesive portion of the spout needs to ensure a length that can form such a seal line in front view, and the length of the adhesive portion is It was defined by the calculation formula. Note that, as shown in FIG. 14, the bonding portion width d constituted by the spout formation line (I) and the formation line (II) is the two of the formation line (I) and the formation line (II). This is the distance d between the formation line (I) and the formation line (II) in the perpendicular line of the line (L1) connecting the intersection points (P1, P2).

  As is apparent from the above formulas (1) and (2), the length of the adhesive portion varies depending on the adhesive portion width d constituted by the spout formation line (I) and the formation line (II). In addition, the length of the said adhesion part should just secure the length shown by said Formula (1), (2), and does not need to comprise the curve according to the said Formula. Therefore, it may be rectangular in front view, with the longest of the above formulas (1) and (2) being the length from the upper end of the bonded portion.

If such a spout is used for the pouch container main body as shown in FIG. 7, a cylindrical pouch container with a spout targeted in the present invention is obtained.
Under the present circumstances, the inner periphery of the trunk | drum of the said cylindrical pouch container with a spout is 4-25 times the radius R which comprises the formation line (I) of a spout, More preferably, it is 5.3-7.2 times, Especially Preferably it is 6.0 to 6.6 times. The spout is not limited to the inner periphery of the body of the pouch as long as it can be attached, but if the inner periphery of the body is adjusted to the above range, the body can be easily set to the radius R after filling the contents in the pouch container. It can be maintained in a cylindrical shape.

  The seal line (70a) of the folding sheet which comprises the top | upper surface part at the time of fixing the said spout is demonstrated using FIG. Fig.15 (a) is a side view of the said spout, FIG.15 (b) is a top view of the pouch container before the spout insertion which opened the folding sheet | seat by the folding line (70c). When the spout of FIG. 15 (a) is inserted into the pouch container body of FIG. 15 (b) to make a bag, the bottom surface portion is the farthest seal point from the folding line (70c) of the folding sheet (70). Is a seal line (70b) composed of a curve of ASinθ, and the target is sealed around the folding line (70c). A portion of the top surface where there is no spout is sealed with the same seal line (70b).

  On the other hand, on the side where the spout (50) is fixed, as shown in FIG. 12, the width of the bonding portion (20) of the spout (50) is d, and the bonding depth from the upper end of the folded sheet is a. When the radius of the pouch is R, bonding is performed with a seal line having a bonding depth (a) based on the following formula (1).

前記したように、シールラインを上記式（１）で構成すると、図１２に示すように、パウチ中央縦断面視、パウチのほぼ中央部から注出口に向かって直線ｂで示す傾斜を構成しうる注出口付き円筒パウチを製造することができる。

As described above, when the seal line is configured by the above formula (1), as shown in FIG. 12, the pouch center longitudinal sectional view, the inclination indicated by the straight line b from the substantially central portion of the pouch toward the spout can be configured. A cylindrical pouch with a spout can be manufactured.

  Further, in the folded sheet (70a), the bonded portion of the folded sheet and the spout may be bonded by a seal line having an adhesion depth (a) based on the following formula (2).

前記したように、シールラインを上記式（２）で構成すると、図１３に示すように、パウチ中央縦断面視、パウチの端部から注出口に向かって直線ｂで示す傾斜を構成しうる注出口付き円筒パウチを製造することができる。

As described above, when the seal line is configured by the above formula (2), as shown in FIG. 13, the pouch can be configured to have an inclination indicated by a straight line b from the end portion of the pouch toward the spout, as shown in FIG. A cylindrical pouch with an outlet can be manufactured.

  That is, as shown in FIG. 15 (b), the seal between the folding sheet (70) on the side where the spout is fixed and the spout (50) is expressed by the above formula (1) at the spout bonding portion (20). ) Or formula (2), and both sides of the seal line are sealed by ASinθ in the same manner as the seal line (70b). For convenience, an imaginary line of ASin θ is shown by a broken line at the spout adhesive portion, and FIG. 15A shows a seal line (70a) according to the above formula (1) of the spout adhesive portion (20). Shown in broken lines. In addition, the adhesion part (20) of a spout and a trunk | drum sheet | seat (60) do not require a specific seal line. In the adhesive part (20) of the spout, the surface that comes into contact with the trunk sheet is a forming line (I) composed of a curve with a radius R when viewed from the bottom, so that the adhesive part (20) and the trunk sheet (60) This is because a predetermined adhesive force and a cylindrical shape can be ensured by stacking them together with a predetermined width.

  In the present invention, the bonding between the trunk sheets, the bonding between the trunk sheet and the folding sheet, and the bonding between the trunk sheet or the folding sheet and the spout may be performed with an adhesive or the like. It is preferable that the sheet, the folded sheet, and the spout are made of a heat-fusible resin and bonded to each other or fixed by heat-sealing. Therefore, in the present invention, a body sheet or a folded sheet and a film in which a heat-fusible resin layer is formed at least on the innermost layer can be suitably used. Moreover, in order to ensure gas barrier property by a use, the laminated | multilayer film which laminated | stacked gas barrier property layers, such as aluminum foil, in any layer may be sufficient.

  As the member constituting the pouch, a laminated film mainly composed of plastic is mainly used, but is not particularly limited, and the usage conditions such as the type of contents to be filled and the presence or absence of heat treatment after filling are used. A suitable one can be selected as appropriate. Specifically, the following laminated films can be preferably used.

(1) PET film / adhesive / aluminum foil / adhesive / ON film / adhesive / PE film (2) PET film / adhesive / ON film / adhesive / aluminum foil / adhesive / PE film (3) PET Film / adhesive / EVOH film / adhesive / ON film / adhesive / PE film (4) PET film / adhesive / uniaxially stretched PP film / adhesive / aluminum foil / adhesive / PP film (5) PET film / Adhesive / (silica or alumina deposited layer) ON film / adhesive / PP film In the above configuration, the PET film is a biaxially stretched polyethylene terephthalate film, the ON film is a biaxially stretched nylon film, the PP film is a polypropylene film, and the CPP film is Unstretched polypropylene film, EV H films ethylene - vinyl copolymer saponified film acetate, (silica or alumina vapor deposited layer) ON film is intended to refer to a biaxially stretched nylon film with a deposit of silica or alumina.

  In addition, the folding sheet (70) should just be able to form the said seal line (70a, 70b), Therefore, you may cut | disconnect with the cut line (74) shown in FIG.15 (b). Thereby, the area of an unnecessary heat-fusion part can be reduced. In FIG. 15B, for the sake of explanation, cut lines are shown only on a part of the pouch container body, but both ends of the top surface portion and the bottom surface portion can be cut with the cut lines.

  If the said pouch container can comprise the said shape, there will be no limitation in a manufacturing method in particular. For example, as shown in FIG. 16, the folding sheets (70) are respectively inserted above and below the two body sheets (60), and then sealed with the ASinθ seal line (70b) on the bottom surface and the top surface, At the same time, both ends of the body sheet (60) are heat sealed. In FIG. 16, the seal line (70b) and the planned insertion position of the spout bonding portion (20) are indicated by broken lines. In the heat sealing step, when four sheets constituting the bottom surface portion are overlapped and heat sealed so as to constitute the ASinθ seal line from above and below, adhesion between the body sheets having no heat-bonding property is avoided. Thus, the folded sheet (70) and the body sheet (60) at the bottom can be bonded in a predetermined shape. In addition, the folding sheet (70) which comprises a top | upper surface part inserts a heat seal shielding board etc. along a folding line (70c), and performs heat sealing by the sealing line of ASin (theta) to the said folding sheet (70b). And the heat sealing of the folded sheet (70a) can be avoided.

  Moreover, in this invention, in order to prevent dissociation of the heat fusion part of the folding sheet | seat (70) and trunk | drum sheet | seat (60) heat-sealed when comprising a top | upper surface part and a bottom face part, 70), a semicircular cut is preferably formed as shown in FIG. It is preferable that the body sheet (60) is heat-sealed during heat sealing by this cutting, and the folding sheet (70) swells to the outside of the pouch when the folding sheet (70) is opened according to the filling of the contents. Therefore, the self-supporting stability of the cylindrical pouch with the spout can be further improved. Such heat-sealing between the body sheets by cutting is referred to as a point seal. In FIG. 16, the point seal portions are indicated by P1, P2, and P3.

  In addition, after heat-sealing the both ends of a trunk | drum sheet | seat (60), if a side seal | sticker (80) of a trunk | drum is bent to one side of a trunk | drum sheet | seat (60), a crease | fold will be formed toward a trunk | drum sheet | seat. it can. When the signature is formed, it is possible to prevent the side seal (80) from projecting to the outer periphery of the trunk part after the pouch container is filled with the contents, and to keep the trunk part in a more cylindrical shape.

  Next, the spout prepared in advance is attached to the pouch container body. At this time, the spout is inserted so that the body portion and the forming line (I) are in contact with each other, and the folding sheet and the forming line (II) are in contact with each other. When fixed, a cylindrical pouch container with a spout which can be used in the present invention can be manufactured.

  This cylindrical pouch container with a spout is flat before filling the contents, but the barrel is cylindrical after filling the contents, so it has excellent self-supporting stability, excellent design, and demand for over-the-counter sales. Can attract the attention of the person.
