Description

  The present invention is a bag with a spout in which a flowable content is hermetically packaged, and the position stability of the spout and the opening when the content is taken out by opening the spout connected to the body portion. It relates to a bag with a spout which is excellent in properties.

  Flowable contents such as liquid detergents and liquid shampoos are often sealed and packaged in a pouch with a spout formed to protrude from the body, and shampoos and rinses are for refilling. Such a bag with a spout is filled and marketed.

  As such a bag with a spout, there is a refillable pouch in which a groove-shaped notch that can fix the position of the spout is formed in the lower seal portion of the spout (Patent Document 1). Since this refill pouch is made of a flexible material, the contents may overflow from the top when the body is gripped by hand, or if the opening of the refill container is small, the spout may be held in the opening of the container. It was made in view of the difficulty. According to the above configuration, since the groove-shaped notch that can fix the position of the spout is formed, the container and the refill pouch are not displaced from each other, and the contents in the refill pouch are in a stable state. You can squeeze things out.

  In addition, a self-supporting bag in which a notch portion is formed in the heat seal portion on at least one side of the spout portion, and an opening means is formed in the spout portion, the opening means including the spout portion. There is also a self-supporting bag formed so as to be cut into a shape recessed from the both sides to the central portion (Patent Document 2). In the case where a narrow spout part is formed in a part of the upper part of the bag, when the contents are transferred to the refill container, the mouth of the spout part may not open well and may be blocked in the middle. If the width of the outlet portion is widened, the stability at the time of transfer is lowered, and if the diameter of the transfer container is small, the contents are spilled. The above Patent Document 2 is made in view of this problem. According to the above configuration, when the spout is opened, it is opened in a shape recessed inward, so even if the width of the tip of the spout is narrow, the deepest portion of the shape recessed inward is the starting point and the inside is on both sides. The opening is large and the contents can be poured out smoothly.

  Furthermore, there is also a bag with a spout, in which a pour-out assisting member in which ridges are formed on the edge of a long tape base material is stuck inside the spout portion (Patent Document 3). Since the opening and shape retention of the spout can be avoided by the pouring auxiliary member formed with the ridges, the spout can be prevented from being bent or bent and the contents can be easily poured out. It can be done.

  On the other hand, from the vicinity of the tip of the spout, from the viewpoint of increasing the manufacturing process when the spout auxiliary member is arranged at the spout, the empty bag with the spout is thicker, and thus costs storage and transportation. A rod-shaped first emboss is formed to protrude toward the outside of the bag toward the inside of the bag, and a downward arc-shaped or V-shaped second emboss is formed that is longer than the width of the base of the spout portion. There is also a bag with a spout (Patent Document 4). Even if the bag is turned upside down when the contents are poured out by opening the contents with the first embossing, the shape retention of the body is secured by the second embossing and the contents are spouted. It can move smoothly, and the contents can be transferred safely and easily to the end.

  However, in the pouch described in Patent Document 1, the stability of the spout part and the container is ensured by hanging the groove-shaped notch part of the pouch spout part on the edge of the refill container. It may become blocked and it will be difficult to discharge the contents.

  On the other hand, in the self-supporting bag described in Patent Document 2, the opening of the spout is ensured by the opening means that opens in a shape recessed inward, but the spout formed by protruding from the trunk is the base. Thus, the bag is likely to bend in the vertical direction or the front-back direction, and the spout may be blocked by such deformation of the spout.

  Moreover, although the bag with a spout described in Patent Document 3 is excellent in shape retention, the manufacturing process is complicated, and the bag with the spout increases in thickness due to the spout assisting member, thereby increasing the storage volume. In addition, the manufacturing unit price increases due to the arrangement of the pouring auxiliary member. As a storage bag for a product such as a liquid detergent that is inexpensive, it is desired to develop a bag with a spout that can be prepared at a lower cost.

  Furthermore, the bag with a spout described in Patent Document 4 is excellent in shape retention of the opening even in a long spout by the first emboss and the second emboss, and the contents are stably guided to the spout. However, if the spout part is long, it will bend greatly at the base and the front and back sides of the bag, and this bending will cause the position of the spout part to become unstable and the spout part will be blocked. It may be difficult to discharge things.

  That is, in a bag with a spout having a spout portion formed in a corner portion, the spout portion is composed of a tip portion and side seals disposed on both sides thereof, and the side seal and the side seal or upper seal. In general, they are connected by a shoulder seal. When such a bag with a spout is filled with the contents and tilted or inverted, the spout portion becomes narrower at the angle formed by the shoulder seal and the side seal, so that the spout portion faces downward in the bag. It is easy to bend to the back side or the front side of the bag at the base of the spout part. In addition, the spout portion is closed by such deformation as bending, so that the pouring operation cannot be performed smoothly.

  An object of this invention is to provide the bag with a spout which can be manufactured cheaply and simply, and is excellent in the positional stability and openability of a spout part in view of the said present condition.

  As a result of examining the bag with a spout in detail, the present inventors have formed an emboss projecting outward from the surface of the shoulder seal on the shoulder seal. The deformation of the spout can be avoided, the position of the spout can be stabilized by the avoidance of such deformation, the spout can be easily inserted into the refill container, and bending can be avoided. It has been found that embossing formed on such a shoulder seal can be easily and quickly performed in the cooling process of the shoulder seal, and the present invention has been completed.

That is, according to the present invention, the outer periphery of the body is heat sealed by the side seal, the bottom seal, and the upper seal, and the body is communicated between the side seal and the upper seal, and both sides and the tip are heat sealed. A pouch with a spout provided with a spout portion,
One side portion of the spout portion is connected to a lower shoulder seal from the side seal toward the trunk portion, and an emboss is formed on the lower shoulder seal so as to protrude outward from the surface of the lower shoulder seal. And
The lower shoulder seal has a portion wider than the width of the side seal , the inner seal line is substantially linear, and the outer seal line is substantially U-shaped, The purpose is to provide a bag with a bag.

  In the present invention, a first emboss and a second emboss projecting outward from the bag surface are further formed, and the first emboss is arranged from the vicinity of the tip end portion of the spout portion toward the barrel portion. The second embossing is provided on the barrel side from the base of the spout port, and the angle between the two ends is wider than the width of the base of the spout and the first emboss is formed. An object of the present invention is to provide a bag with a spout, which has a bar shape or an arc shape with an acute angle.

  Further, according to the present invention, an angle formed by a center line of the spout portion and an extension line of the side seal is 25 to 65 °, and an angle formed by the side seal and an inner seal line of the lower shoulder seal Is 25 to 90 °, and provides the bag with the spout.

  Further, according to the present invention, a notch portion is provided in the heat seal portion on at least one side of the spout portion, and an opening means having a shape recessed inward from both sides to the center of the spout portion is provided. It aims at providing the bag with the said spout characterized by these.

Moreover, this invention aims at providing the said bag with a spout characterized by the said bag with a spout having self-supporting property.
A further object of the present invention is to provide a product in which the bag with a spout is filled with a fluid content.

  The bag with the spout of the present invention can ensure the opening of the spout by simply forming a predetermined emboss on the lower shoulder seal connected to the spout. For this reason, it can manufacture simply using the conventional manufacturing apparatus, and the raise of manufacturing cost can be avoided.

  Since the bag with a spout of the present invention can secure the rigidity of the lower shoulder seal by the embossing formed on the lower shoulder seal, it can prevent the spout from being bent and ensure the stability of the position of the spout. For this reason, even when a spout part is elongate, insertion of a spout part at the time of using as a refilling pouch etc. can be performed easily.

A pouch with a spout provided with a spout portion that is sealed, wherein one side portion of the spout portion is connected to a lower shoulder seal from the side seal toward the trunk portion, and An embossing projecting outward from the surface of the shoulder seal is formed on the shoulder seal.

The second of the present invention is a product in which the bag with a spout is filled with a fluid content. Hereinafter, the present invention will be described in detail with reference to the drawings showing examples of preferred embodiments of the present invention.
(1) Bag with spout and product An example of a preferred embodiment of the bag with spout of the present invention is shown in FIGS. As shown in FIG. 1, the bag with a spout (100) according to the present invention has an outer periphery of a trunk (A) by a pair of left and right side seals (10, 10 '), a bottom seal (20) and an upper seal (30). Is heat-sealed, communicated with the body (A) between the side seal (10) and the upper seal (30), and thermally welded by both side seals (40, 40 ') and a tip seal (43). The spout part (B) made is arrange | positioned. One side seal (40) of the spout port (B) is connected to a lower shoulder seal (13) from the side seal toward the trunk (A), and the lower shoulder seal (13). ) Is formed with an emboss (15) protruding outward from the surface of the lower shoulder seal (13). The other side seal (40 ′) of the spout port (B) is connected to the upper seal (30) via the upper shoulder seal (33). In FIG. 1, a notch (45) as an opening means and an arc-shaped cut line (47) that curves toward the body (A) are formed at a position near the body (A) of the spout (B). The aspect made is shown.

  In the bag with a spout (100) of the present invention, the lower shoulder seal (13) is formed with an emboss (15) projecting outward from the surface of the lower shoulder seal (13). (13) is provided with rigidity, whereby deformation of the lower shoulder seal (13) and the side seal (40) is avoided, the angle between the two is stabilized, and the upper and lower, left and right of the spout (B) Bending can be prevented, and thereby the opening of the spout (B) is ensured. Since the stability of the position of the spout (B) is ensured, the operability when the spout (B) is inserted into the refill container is excellent. Moreover, since the openability is ensured, the content can be smoothly poured out, and can be quickly discharged without taking a long time. The lower shoulder seal (13) may be formed by any method, but in order to clarify the range, in the present invention, as shown in FIG. A lower shoulder seal (13) is defined between the extension line (X) and the upper end line (Y) inclined to the body (A) side of the side seal (10).

  FIG. 1 has a gusset portion formed by folding the bottom film inward and inserting it to the bottom film turn-up portion (23), and the notch portions (25) of the semicircular bottom film are formed in the vicinity of both lower ends of the bottom film. The bottom seal (20) is provided and heat-sealed, and the bottom seal (20) has a self-supporting state in which the inside of the gusset portion forms a seal pattern in a shape of a ship bottom rising from the center of the bottom portion to both sides. .

  As shown in FIG. 2, the bag with a spout (100) of the present invention has a first emboss (50) and a second emboss (60) protruding outward from the surface of the bag. Good. The first embossing (50) is preferably in the form of a rod arranged from the vicinity of the tip (43) of the spout (B) toward the body (A), and the second embossing (60) is an angle formed by the first embossing (50) between the both ends of the spout portion (B), which is wider than the width of the base portion of the spout, from the base portion of the spout portion (B). Is preferably a rod or arc having an acute angle.

  The first embossing (50) is formed so as to protrude to the outside of the bag (100) with the spout, and rigidity is imparted to the film by such irregularities, so that the opening of the spout (B) can be secured. Further, when a rod-shaped or arc-shaped second emboss (60) having an acute angle with the first emboss (50) is formed, the body side ( A) swells to prevent blockage due to adhesion between the body films. Moreover, since the contents move from both sides of the second embossing (60) toward the spout part (B), a flow path for the contents is secured, and the flow of the contents to the spout part (B) is smooth. The contents can be poured out stably until the end.

  For convenience, FIGS. 1 and 2 show an aspect in which the entire circumference is heat-sealed. However, the bag with a spout (100) of the present invention has an unsealed portion in either. May be. For example, if the upper seal (30) is an unsealed part, it can be used as a filling port for contents. Since the upper seal (30) has a wide mouth, the contents can be filled easily and smoothly. If the upper part is heat-sealed after filling the contents, a product in which the contents are sealed can be obtained.

  As a trunk | drum film and a bottom part film which comprise the bag with a spout part of this invention, the laminated | multilayer film which mainly has a plastics mainly can be used. For example, a laminated film in which a sealant layer is laminated on the inside of the base film layer is used, and depending on the type of contents to be filled, the presence or absence of heat treatment after filling, the filling amount, etc., a gas barrier layer, a light shielding layer, You may use the laminated film which laminated | stacked the strength improvement layer etc. The body film and the bottom film may be the same or different.

In addition to these, contents having fluidity such as powder and granules can be exemplified.

In the present invention, the above-mentioned fluid content can be filled into a bag with a spout to obtain a product.
(2) Spout portion The spout portion (B) disposed in the spout-equipped bag of the present invention is formed between the side seal (10) and the upper seal (30) as described above. It communicates with the trunk (A). One side (40) of the spout (B) is connected to the lower shoulder seal (13) from the side seal (10) to the body (A), and the other side (40 ′) is The upper shoulder seal (33) descends from the upper seal to the body (A).

The shape of the spout portion (B) can be variously adjusted by selecting the shape of the shoulder seals (13, 33), the side seals (40, 40 '), and the tip seal (43). it can. Preferably, as shown in FIG. 3, the angle (θ1) formed by the center line (C) of the spout part (B) and the extension line of the side seal (10) is 25 to 65 °, more preferably 30 to 60. The angle (θ2) formed by the side seal (10) and the inner seal line of the lower shoulder seal (13) is 25 to 90 °, more preferably 25 to 60 °. If it is this range, it is because the latching to the mouth part of a refilling container is easy, and the movement from the trunk | drum (A) of a content to a spout (B) is also easy. In the present specification, the angles formed by the shoulder seals (13, 33), the side seals (40, 40 '), the side seals (10), the upper seals (30), etc., unless otherwise defined. Means the angle formed by the body part (A) side or the spout part (B) inner seal line, and when these form a curve, it means the tangent at the maximum value.

It is preferable to form an opening means in the spout part (B). The opening means may be an opening instruction line such as a cut line by printing, an opening instruction mark, a character, etc., and in combination with these, a notch or a half cut line that facilitates opening by tearing or the like may be formed. Further preferred. When the half-cut line is provided, it can be provided by mechanical means using a blade, but in order to stably provide the depth at a desired depth, it is more preferable to use a method by laser light irradiation. One half cut line may be used, but a plurality of half cut lines may be used. Further, the half-cut line may be a straight line or a curved line such as an arc. Moreover, although a notch may be formed in the front-end | tip part (43) side of a spout part (B), you may arrange | position on a trunk | drum (A) side. FIG. 3 shows a mode in which a notch (45) and a linear half-cut line (47) are formed as opening means in the vicinity of the tip of the spout (B). When the notch (45) and the half-cut line (47) are formed on the tip end (43) side of the spout part (B), the spout part (B) after opening is formed to be elongated, and the mouth of the refill container The elongated spout part (B) can be easily inserted into the part. In addition, in FIG. 3, the side part seal (40 ') and tip part (43) of a spout part (B) connect, and the aspect which forms the holding part (40'a) at the time of opening is shown.

The size of the bag with a spout according to the present invention can be appropriately selected depending on the filling amount of the contents. Similarly, the angle formed by the center line (C) of the spout (B) and the extension line of the side seal (10). ( Θ1 ) is 25 to 65 °, and the angle (θ2) formed by the side seal (10) and the inner seal line of the lower shoulder seal (13) is in the range of 25 to 90 °, The shape and size of B) can be selected as appropriate.

In the bag with the spout of FIG. 3, the angle (θ1) between the center line (C) of the spout (B) and the extension of the side seal (10) is 45 °, and the bottom seal (10) and the bottom The angle (θ2) between the shoulder seal (13) and the inner seal line is 35 °, and a mode different from this is shown in FIG. The bag with the spout of FIG. 4 has an angle (θ1) between the center line (C) of the spout (B) and the extension of the side seal (10) of 60 °, and the bottom seal (10) and the bottom The angle (θ2) between the shoulder seal (13) and the inner seal line is 28 °. Further, a notch (45) is formed on the side of the body seal (A) in the length direction of the side seal (40 ′), and a plurality of half-cut lines (47) as opening means are formed. When the spout part (B) after opening is short, the spout part (B) is locked to the mouth part of the refilling container using the outer peripheral part of the lower shoulder seal (13) as a guide part, The contents can be easily guided to the mouth from the open end. In FIG. 4, the gap (I ′) formed by the side seal (40 ′) and the upper shoulder seal (33) so that the spout (B) can be easily locked to the mouth of the refill container. Is a groove-shaped notch.

  When the half-cut line (47) as the unsealing means is an arc shape that curves toward the body (A), an arc-shaped half-cut line (47) is provided on the inside as the unsealing means. . The half-cut line (47) is preferably inwardly recessed from both sides to the center of the spout (B), and may be V-shaped on the inside. By doing so, when the spout part (B) whose tip is opened is locked to the mouth part of the refilling container and the bag is tilted, the inner depression or the V-shaped deepest part starts from that point. The inside expands widely on both the left and right sides, and the contents quickly flow out of the body part (A), and the flow speed is increased, so that the pouring operation can be performed quickly. Moreover, the deepest part may be formed on the side seal (10) side below the center line (C) of the spout part (B). By doing in this way, the tendency for the spout part (B) to narrow in the up-down direction of the bag can be prevented. Moreover, if it is a several half cut line, even if a tear direction shifts | deviates, it can open smoothly via any half cut line.

  In addition, when providing a notch as an opening means, a generally used one-letter or V-shaped notch may be used, but if the corner after opening the spout portion using the notch becomes an acute angle, the hand is damaged. Since there is a risk, the corner may have a blunt shape or a round notch.

(3) Shoulder seal As shown in FIG. 3 and FIG. 4, there are two shoulder seals (13, 33) in the bag with spout of the present invention. A portion (13) connecting the side seal (40) and the side seal (10) of the spout port (B), a side seal (40 ′) and an upper seal (30) of the spout port (B). It is the part (33) which connects. The present invention is characterized in that an emboss is formed on the lower shoulder seal (13) connected to the side seal (10).

As described above, the spout portion (B) has an angle (θ1) between the center line (C) of the spout portion (B) and an extension line of the side seal (10), the side seal (10), and the lower shoulder. The angle (θ2) formed with the part seal (13) is preferably in the above range, and the length of the side seal (40, 40 ′), the shape of the shoulder seal (13, 33), and the opening means within the range Can be arbitrarily selected, whereby the length and shape of the spout part (B) after opening can be adjusted. For example, since the spout part (B) shown in FIG. 3 is long and the opening means is in the vicinity of the tip part (43) of the spout part (B), the elongated spout part (B) is opened after opening. It can be inserted into the mouth of the refill container. Moreover, in the aspect shown in the said FIG. 4, since a spout part (B) is short and an opening means exists in the trunk | drum (A) side of a spout part (B), a side part seal | sticker (40) is opened after opening. It is convenient for the mode which latches to the opening part of a refill container and pours out the contents.

  However, regardless of the length of the spout portion (B) or the position of the opening means, if the filled conventional bag with spout is gripped, the lower shoulder seal (13) is distorted. FIG. 5 (a) shows a bag with a spout filled with the contents, which has a short spout (B) and no embossed bottom shoulder seal (13). FIG. 5B shows an inverted state and an aspect in which the bag with a spout of the present invention in which the embossing (15) is formed on the lower shoulder seal (13) is inverted.

  When the bag filled with the contents is inverted, the contents on the bottom seal (20) side shift to the top seal (30) side. Since the spout part (B) is arranged in a narrow mouth shape between the side seal (10) and the upper seal (30), when the body part (A) is gripped, the side of the lower shoulder seal (13) An arc line (CL) is formed between the base on the seal (10) side and the base on the upper seal (30) side of the upper shoulder seal (33), and the body (A) side of the arc line (CL) is the content Inflates with things. At this time, in the conventional bag with a spout where the lower shoulder seal (13) is not embossed, the lower shoulder seal (13) is distorted as shown in FIG. B) slopes from the base (D) to the front or back side of the bag. Due to the inclination of the spout part (B), it becomes difficult to lock the refill container, and the base part (D) of the spout part (B) is blocked by the distortion, and the inside of the spout part (B). Also block. This blockage is not easily released, and even if the spout part (B) is opened, it is not easy to open the spout part (B) after opening.

  However, when a predetermined emboss (15) is formed on the lower shoulder seal (13), rigidity is imparted to the lower shoulder seal (13), and therefore, as shown in FIG. When the upper part of 13) is pressed in the direction of arrow (I), a force is applied to the spout part (B) in the direction of arrow (II) by the rigidity of the lower shoulder seal (13), and the base part of the spout part (B) is It can be opened. Moreover, since the base part of the spout part (B) can be moved from the base part (D) of the spout part (B) to the tip part (43) side by opening the base part, the trunk part (A) and the spout part The contents are introduced between (B) and the inclination of the spout (B) is also prevented.

  The effect of the embossing (15) formed on the lower shoulder seal (13) is not limited to the spout (B) shown in FIG. 5 (b). FIG. 6A shows a bag with a spout filled with the contents, which has a long spout (B), and a first emboss (50) and a second emboss ( 60), and a conventional bag with a spout having no emboss on the lower shoulder seal (13) is inverted, and FIG. 6 (b) shows an emboss (15 on the lower shoulder seal (13). ) In which the bag with a spout of the present invention is formed upside down.

  When the bag filled with the contents is inverted, the contents on the bottom seal (20) side shift to the top seal (30) side. Since the spout part (B) is arranged in a narrow mouth shape between the side seal (10) and the upper seal (30), if the body part (A) is gripped, the presence or absence of the second emboss (60) Regardless, a circular arc (CL) is formed between the base on the side seal (10) side of the lower shoulder seal (13) and the base on the upper seal (30) side of the upper shoulder seal (33), The body (A) side of the arc wire (CL) swells with the contents. In the conventional bag with a spout where the lower shoulder seal (13) is not embossed, as shown in FIG. 6 (a), the lower shoulder seal (13) is distorted, and the long spout shown in FIG. In the part (B), the bag is particularly bent toward the front side and the back side, and the position of the spout part (B) of the narrow mouth becomes unstable.

  However, if a predetermined emboss (15) is formed on the lower shoulder seal (13), rigidity is imparted to the lower shoulder seal (13), and therefore, as shown in FIG. When the upper part of (13) is pressed in the direction of arrow (I), a force is applied to the spout part (B) in the direction of arrow (II) by the rigidity of the lower shoulder seal (13), and the base part of the spout part (B) Can be opened. In particular, when the first emboss (50) and the second emboss (60) are formed on the body (A), the force in the direction of the arrow (II) from the lower shoulder seal (13) is quickly applied. Even if it is a long spout part (B), the base part of the spout part (B) can be opened, so that the contents can be opened from the base part (D) of the spout part (B) to the tip part. It can move to (43) side, can bend the bag of the spout part (B) to the front side or the back side, and can prevent the spout part (B) from being inclined.

  In the present invention, the shape of the lower shoulder seal (13) can be appropriately selected depending on the type of contents and the filling amount. In the bag with a spout (100) of the present invention, the angle formed by the side seal (10) and the inner seal line of the lower shoulder seal (13) is preferably 25 to 90 °. The width of the part seal (13) need not be the same width from the side seal (10) side to the side seal (40) side. As shown in FIG. 7, it is preferable to have at least the same width (W1) as that of the side seal (10) but wider than that. The width (W2) of the widest portion of the lower shoulder seal (13) is 1.5 to 4 times W1, more preferably 2 to 3.5 times W1. By forming such a widest part, rigidity can be imparted to the lower shoulder seal (13), and embossing can be formed over a wide range to further impart rigidity. In addition, the inner seal line at the intersection of the lower shoulder seal (13) and the side seal (40) of the spout (B), or the intersection of the lower shoulder seal (13) and the side seal (10). It is preferable that all of the inner seal lines of the part are formed by arcs. This is because the contents can move smoothly in the trunk (A).

  In the present invention, the embossing (15) formed on the lower shoulder seal (13) is a convex portion protruding outward from the surface of the lower shoulder seal (13). FIG. 8 shows a cross-sectional view of the emboss of the lower shoulder seal (13) formed by sealing two laminated films (F1, F2). The height (H) of the embossed convex portion relative to the surface of the lower shoulder seal (13) can be appropriately selected depending on the thickness of the laminated film (F1, F2) to be used. 0.1 to 1 mm, more preferably 0.3 to 0.5 mm.

  Such embossing (15) may be formed in any range within the range of the lower shoulder seal (13). However, the lower shoulder seal (13) is provided with rigidity so that the spout ( B) is only required to be able to avoid blockage and bending, and it is preferably formed along the longitudinal direction of the lower shoulder seal (13), and is provided so as to be substantially parallel to the inner seal line of the lower shoulder seal (13). It is preferable. More specifically, the inside formed in the range of 0 to 6 mm, more preferably 1 to 5 mm, particularly preferably 2 to 5 mm from the outer periphery of the lower shoulder seal portion (13) is defined as the embossed (15) forming range. can do. For example, FIG. 9A shows a mode in which convex portions are formed on the entire surface of a substantially trapezoidal embossed (15) forming range formed inside at a fixed distance from the outer periphery of the lower shoulder seal portion (13). . In the present invention, as shown in FIG. 9B, two rod-like convex portions substantially parallel to the inner seal line of the lower shoulder seal (13) can be exemplified. Within the above range for forming the embossing (15) formed along the longitudinal direction of the lower shoulder seal (13), the two rod-shaped convex portions are substantially parallel to the inner seal line of the lower shoulder seal (13). Is formed. Further, as shown in FIG. 9 (c), the inner seal line of the lower shoulder seal (13) is within the range of forming the emboss (15) formed along the longitudinal direction of the lower shoulder seal (13). A plurality of rod-like convex portions that intersect substantially perpendicularly with each other may be formed. The ends of the plurality of rod-shaped convex portions are substantially parallel to the inner seal line of the lower shoulder seal (13). Further, if it is formed along the longitudinal direction of the lower shoulder seal (13), it is provided substantially parallel to the inner seal line of the lower shoulder seal (13) as shown in FIG. 9 (d). It may be in the form of a cross made of a combination of a rod shape and a rod shape provided perpendicular to the inner seal line of the lower shoulder seal (13). Further, although not shown, the entire emboss formation range along the longitudinal direction of the lower shoulder seal (13) may be formed by a plurality of dot-like convex portions. That is, in the present invention, it is only necessary to provide an opening to the spout part (B) by forming an emboss projecting outward from the surface of the lower shoulder seal (13) on the lower shoulder seal (13). It is not limited to the embodiment. In FIG. 9, the lower shoulder seal (13) connected to the short spout portion (B) has been described, but the lower shoulder seal (13) connected to the long spout portion (B) is the same. It is. In addition, the convex part which protrudes outside from the surface of the shoulder seal may protrude to the front side or the back side of the bag. The back side of the convex is a concave corresponding to the convex.

  The emboss to be formed on the lower shoulder seal (13) is formed as a cooling mold when the shoulder seal is thermally welded and then cooled in the shoulder seal processing step during bag making. It can be formed by changing to a molded mold and cooling. In general, in the heat sealing step, a predetermined portion is thermally welded and then pressed with a cooled flat plate mold to stabilize the heating portion. In the present invention, the above-described irregularities are formed instead of the flat plate mold. The said embossing can be formed in a lower shoulder seal (13) by cooling the heated lower shoulder seal (13) using a pair of molds. The lower shoulder seal (13) forming the embossing (15) is composed of two laminated films that are heat-sealed and liquid-tight, so that the embossing (15) is formed deeper than expected due to blurring in the manufacturing process, Even if the gaps between the laminated films become thin, the contents are not leaked, so that stable production is possible.

  In the present invention, the shape of the upper shoulder seal (33) connected to the side seal (40 ′) on the upper seal (30) side of the spout portion (B) is not particularly limited. However, the gap (I) between the lower shoulder seal (13) and the side seal (40) and the gap (I ') between the side seal (40') and the upper shoulder seal (33) are the spout portion. It functions as a locking part when the contents are poured out from the open end of (B). Therefore, if the shape of the seal part on the outer periphery of the spout part (B) is a shape that can be locked to the edge part of the mouth part of the refill container, the contents can be stably poured out. FIG. 10 (a) shows an embodiment in which a bag with a spout provided with a spout (B) is opened near the trunk (A), and FIG. 10 (b) shows a spout (B). The aspect with which the provided bag with a spout was opened in the front-end | tip part vicinity of a spout part (B) is shown. In FIG. 10 (a), a protrusion (33a) is formed on the upper shoulder seal (33), whereby the gap (I ′) between the side seal (40 ′) and the upper shoulder seal (33) is increased. It is formed in the shape of a groove. The open end of the spout (B) is guided to the mouth of the refill container through the outer periphery of the lower shoulder seal (13), and the bag is inclined so that the groove-shaped notch (I ′) is formed in the mouth. If it is locked to the edge, even if it is a short spout part (B), the open end of the spout part (B) is stably inserted into the mouth part of the refilling container to perform a stable spout operation. be able to. On the other hand, in the embodiment shown in FIG. 10 (b), since the spout part (B) is long, the open end of the spout part (B) can be inserted deeply into the mouth part of the refill container, thereby stabilizing. Can be dispensed.

  In the present invention, the gap (I) between the lower shoulder seal (13) and the side seal (40) and the gap (I ') between the side seal (40') and the upper shoulder seal (33) are defined as The shape suitable for the pouring operation of the pouring port part (B) can be processed.

(4) Body part As shown in the said FIG. 2, the bag with a spout of this invention is formed with the 1st embossing (50) and the 2nd embossing (60) which protrude outside from a bag surface. May be. The first emboss (50) has a rod shape arranged from the vicinity of the tip of the spout (B) toward the body (A), and the second emboss (60) From the base part of the spout part (B) to the body part (A) side, a rod-like shape whose both ends are wider than the width of the base part of the spout and the angle formed with the first emboss (50) is an acute angle or It is arcuate. In addition, although there exist a spout part (B) side and a trunk | drum (A) side in "the angle | corner which a 2nd embossing and 1st embossment make", in this-application specification, spout part (B ) The angle formed by the side is an acute angle.

  Although FIG. 2 shows a mode in which the arc-shaped second emboss (60) intersects the first emboss (50), it may be provided in a shape in which either one or both are separated at the intersection. For example, two arc-shaped second embosses (60) may be disposed on both sides of the first emboss (50) without intersecting the first emboss (50). Further, the second embossing (60) has a rod shape with an acute angle with the first embossing (50), that is, the first embossing (50) is the center, and the V embossing is directed toward the base of the spout (B). It may be a letter shape. The second embossing (60) is wider than the base of the spout part (B) and is formed so as to surround the communication part between the spout part (B) and the body part (A). If the bag filled with is inclined downward in the spout part (B), the first embossing (50) can be easily opened in a cylindrical shape with good shape retention, and the ribs of the second embossing (60) According to the effect, blockage due to bending near the base of the spout (B) can be prevented, and the flow of the contents after the spout (B) is opened can be promoted.

  In this invention, said 1st embossing (50) may have a wide part (53) in the base vicinity of the spout part (B). The rigidity of the laminated film constituting the body part (A) is enhanced by the wide part (53), and the bending of the spout part (B) can be efficiently avoided. The first emboss (50) extends from the vicinity of the tip (43) of the spout (B) to the body (A). After the second emboss (60) has passed, the first emboss (50) is further on the bottom seal side. You may curve. Rigidity is imparted to the laminated film constituting the body (A) by forming a convex portion in the longitudinal direction in the body (A) by the first emboss (50), the contents are discharged, and the remaining amount is discharged. Even when the number is reduced, the bending of the body (A) can be avoided and a smooth discharge operation can be ensured.

  In FIG. 2, the first emboss (50) and the second emboss (60) are described by double lines in which the inner line and the outer line are parallel. The inner line indicates the highest part of the embossing that protrudes outward from the bag surface. For this reason, the cross section of the emboss (50, 60) has a trapezoidal shape (not shown) with the upper side between the inner lines and the bottom side between the outer lines. On the other hand, the convex part of embossing is not limited to such an aspect. For example, as shown in FIG. 11, when including the aspect which a 1st embossing (50) and a 2nd embossing (60) cross | intersect, the outer side line (50a) of a 1st embossing and a 2nd embossing (60) And the outer line (50a) of the first embossing (50) and the outer line (60a) of the second embossing (60) are connected together (50b). 60b). There are few corner | angular parts in an outer side line, and the contents can be smoothly moved to a spout part (B). In addition, since the space between the outer lines (50b, 60b) is wide, it is possible to avoid adhesion between the laminated films more efficiently.

  Such first and second embosses (50, 60) may be provided only on one laminated film constituting the bag (100), but 2 constituting the body (A) of the bag (100). It is preferable to provide both of the laminated films.

  In the bag with a spout (100) of the present invention, when the first emboss (50) and the second emboss (60) are disposed, the tip of the spout (B) is formed by the first emboss (50). (43) Since the opening of the spout part (B) is assisted from the vicinity toward the body part (A), and the body part (A) side swells along the shape of the second embossing (60), the spout part The adhesion of the laminated film from the base of the part (B) to the second emboss (60) is avoided.

  In order to obtain the effect by the embossing formed on the body part (A) in the present invention more efficiently, the first embossing (50) and the second embossing (60) are preferably connected. Further, the width and height of the emboss (50, 60) are not particularly limited, but when the cross section is trapezoidal, the width between the outer lines is 3 to 15 mm, and the width between the inner lines is It is preferable that it is 1.5-10 mm, and the height shown by an inner side line is a height of about 2-4 mm on the basis of the surface of the laminated film which comprises a trunk | drum (A).

  In this invention, what is disclosed by Unexamined-Japanese-Patent No. 2007-161289 can be applied suitably as a shape and other aspects of the first emboss (50) and the second emboss (60).

  In the present invention, an easily bendable line (70) substantially parallel to the second embossing (60) is further formed in the vicinity of the communicating part between the spout part (B) and the body part (A). Also good. This aspect is shown in FIG. When the bag is tilted after inserting the spout part (B) into the mouth of the refill container, the contents flow toward the spout part (B), but the spout part (B) expands the cylindrical part. Accompanyingly, the easy-bending line (70) in the vicinity of the base of the spout (B) spreads in a cylindrical shape, and further extends from there to the second embossing (60). Since a trunk | drum (A) spreads with sufficient shape retention property, the flow to the spout part (B) of a content can be adjusted more smoothly. As such an easy-bending line (70), those that can expand the body (A) side from the base of the spout (B) in a funnel shape can be widely applied. The easy bending line (70) may be one or may be formed of two or more. Further, the distance between the second emboss (60) and the easy-bend line (70) may be determined as appropriate depending on the size of the bag or the size of the spout, but usually the most Even at close positions, it is preferable to leave an interval of about 7 to 15 mm.

  Such an easy-bending line (70) may be a mechanical means using a cutter, and can be formed by a half-cut line by laser light irradiation. As such an easy-bending line (70), the aspect of Unexamined-Japanese-Patent No. 2007-210629 can be selected suitably, and can be applied.

(5) Bottom seal In the bag with spout (100) of the present invention, the form of the bag body is not particularly limited, and a gusset part is formed at the bottom in addition to a flat bag such as a four-side seal type or a three-side seal type. Any bag such as a bottom gusset type or other standing pouch can be used as long as it can form a narrow spout part in a part of the upper part of the bag (100) by heat sealing. In addition, as the bottom gusset type, the bottom of one laminated film is folded to form a gusset, and the bottom is sealed to the bottom of the ship, and the bottom of the two laminated films constituting the trunk (A) You may have a gusset part formed by inserting the base film folded in half and heat-sealing the edge part of the circumference | surroundings. At this time, the shape of the bottom seal is not particularly limited.

  In the present invention, the bottom gusset type in which the bottom seal is provided with a gusset is most effectively exerted by the embossing effect on the lower shoulder seal (13). The bottom gusset-type bag with a spout (100) can be filled with a larger amount of contents compared to a flat bag. When opening the spout portion (B) of the spout-equipped bag (100) filled with the contents and gripping the trunk portion (A), as shown in FIG. 5 (a) and FIG. 6 (a), The internal pressure rises in the body (A), causing distortion between the lower shoulder seal (13) and the side seal (40), and the base (D) of the spout (B) rather than the flat bag. Is easy to bend. When such bending occurs, the contents cannot be transferred to the spout part (B) even if the internal pressure is increased, and the blockage is maintained. However, according to the present invention, even with such a bottom gusset type, the embossing is formed on the lower shoulder seal (13) to provide rigidity and avoid bending of the spout (B). The contents can be smoothly poured out from the spout (B).

  In addition, it is particularly preferable that the bottom gusset-type bag with a spout (100) is self-supporting after filling the contents, because the bag (100) can be easily handled and the display effect at a store is excellent. .

  As the bottom seal constituting the bag with spout of the present invention, preferably, the bottom film is folded back and inserted between the lower portions of the two laminated films constituting the trunk portion (A), and folded inside. A semi-circular spot-shaped bottom film cutout is provided near the bottom of both sides of the bottom film, and the gusset is heat-sealed with a bottom-bottom-shaped seal pattern that has a concave shape such as a curved bar from the inside to the center. To form. By forming the bottom portion of the bag (100) in this way, when the contents are filled, the bottom portion of the bag is widened back and forth to form a flat bottom surface, and a leg by a heat seal portion is formed on the outer periphery of the bottom portion. Since the part is formed, it is excellent in independence and appearance.

  In addition, the ship-bottom-shaped seal pattern for heat-sealing the gusset portion is a ship-bottom-shaped seal pattern in which the inside is concave in a curved rod shape from both sides to the center, and the inner center is low with a predetermined width, It may be a ship-bottom-shaped seal pattern that rises in a rod shape with an inclination from both ends to the sides on both sides of the bag.

(6) Manufacturing method It does not specifically limit as a manufacturing method of the bag with a spout of this invention. For example, depending on the type of bag with spout, a bag making machine that can make bags is used, and a heat-sealing device necessary to form the spout is formed on this, and notches and notches are formed on both sides of the spout. A punching device for forming, an punching device for forming an unsealing means at the spout part, a laser beam irradiation device, a hot embossing device and a hot press device for forming the first embossing and the second embossing on the body part, By attaching an embossing die for forming embossing to the cooling device and the shoulder seal, it can be continuously manufactured using a conventional manufacturing process.

Hereinafter, a case of producing a bag (100) with a spout having a bottom gusset type and provided with a first emboss (50) and a second emboss (60) will be described.
First, the first embossing (50) and the second embossing (60) are formed on each of the two laminated films constituting the body (A) by a hot embossing device, and then at a predetermined position by a laser light irradiation device. A half-cut line is formed as an opening means. Next, the laminated film constituting the body part (A) is overlaid so that the heat seal layer faces each other, and the bottom film is folded back and inserted so that the heat seal layer is on the bottom, and the heat seal device is used. The side seal portion (10, 10 '), the bottom seal portion (20), and the upper and lower shoulder seal portions (13, 33) are sequentially heated and welded and cooled to stabilize each welded portion. In the present invention, when the shoulder seal is cooled, as a mold for cooling the shoulder seal, a mold in which irregularities protruding outward from the lower shoulder seal (13) is used, and the lower shoulder seal is used. An emboss (15) can be formed on (13). Then, if the outer periphery is punched into a predetermined shape by a punching device, the unsealed bag (100) with only the upper seal (30) can be manufactured. If the contents are filled from the unsealed portion and the upper seal (30) is heat sealed, a product filled with the contents can be manufactured. In addition, as shown in FIG. 1, when the notch part (25) of a semicircular bottom film is provided in the vicinity of the both lower ends of the said bottom film and it heat-seal | fuses, a gusset part will be fixed in front and back, and self-supporting property will be provided. Is done. In the present invention, as described above, by simply changing a part of the mold used in the cooling step, the bag with a spout (100) in which the opening of the spout portion is secured is manufactured simply and inexpensively. be able to.

  In addition, when manufacturing the bag with a spout (100) without the first emboss (50) and the second emboss (60), the bag with a spout (100) is manufactured without performing the corresponding process. That's fine. Moreover, when arrange | positioning an easy bend line (70) below the spout part (B), when forming the half cut line of an opening means by a laser beam irradiation apparatus, an easy bend line ( 70) may be formed.

EXAMPLES Next, although an Example is given and this invention is demonstrated concretely, these Examples do not restrict | limit this invention at all.
Example 1
As shown in FIG. 13, a first emboss (50) and a second emboss (60) are disposed on the body (A), and a notch (45) and five spouts (B) are provided as opening means. Length (L) 230mm, width (W) 120mm, center line (C) of spout part (B) and extension line of side seal (10) with half cut line (47) bent on the base side The angle (θ1) between the side seal (10) and the inner seal line of the lower shoulder seal (13) is 35 °, the side seal (10, 10 ′), side part The seal (40, 40 ') and the tip seal (43) each have a width of 5 mm, the maximum width (W2) from the inner seal line of the lower shoulder seal (13) is 14 mm, from the bottom to the bottom fold (23) A bag with a spout having a width of 35 mm was produced. The lower shoulder seal (13) is formed with an emboss (15) that protrudes 0.5 mm from the surface of the lower shoulder seal (13) on the inner side with a width of 4 mm from the outer periphery. It is a side seal (10) from the center line (C).

  The body part is a biaxially stretched nylon film (hereinafter referred to as ON film) (thickness 15 μm) / character, picture printing layer / adhesive / linear low density polyethylene film (hereinafter referred to as L·L) from the outer layer to the inner layer. A laminated film (thickness 130 μm) is used, and the bottom part is an ON film (thickness 15 μm) / white solid printing layer / adhesive / L / LDPE film (thickness 120 μm) from the outer layer toward the inner layer. The laminated film was used. The above-mentioned films were bonded by a dry lamination method using a two-component curable polyurethane adhesive for dry lamination.

  The first emboss (50) and the second emboss (60) whose maximum height is 2.5 mm by an embossing machine, and a half-cut line as an opening means by a laser beam irradiation device at a predetermined position of the original fabric (47) was formed. The two original fabrics were overlapped so that the L / LDPE films face each other, and a bottom film having a width of 70 mm was folded and inserted into the bottom so that the heat seal layer was on the outside. Subsequently, a bottom seal, a spout portion, and a side seal and a shoulder seal were sequentially formed. In addition, after the heat sealing of the shoulder seal, embossing was performed simultaneously with the cooling of the shoulder seal by using a cooling mold formed with unevenness against the shape of the embossed (15) to stabilize the heat seal portion.

Subsequently, the outer periphery was punched into a predetermined shape by a punching device, and a bag (100) with a spout, in which only the upper seal (30) was not sealed, was manufactured.
(Example 2)
The bag with a spout (100) obtained in Example 1 was filled with 350 ml of the content from the opened upper seal (30), and the upper seal (30) was sealed to obtain a product.

In this product, the position of the spout portion (B) was stable without being bent to the front side or the back side of the bag even when the body portion was gripped.
Next, the spout part (B) is opened from the notch (45) along the half-cut line (47), and the spout part (B) is inserted into the mouth part of the refill container whose inner diameter is 26 mm. Inserted. Since the position of the spout (B) was stable, it was easy to insert.

  When the contents are poured out by tilting the bag, the contents on the barrel side are easily transferred to the spout part (B) because the spout part (B) is opened without being bent. We were able to transfer things smoothly. At that time, the spout (B), its base, or the inside thereof was not bent and blocked during the pouring.

(Example 3)
Using the same film as in Example 1, as shown in FIG. 14, a notch (45) and a half cut line (47) bent on the base side of the five spouts (B) were disposed as the opening means. Length (L) 230 mm, width (W) 120 mm, angle (θ1) between the center line (C) of spout (B) and the extension of side seal (10) is 60 °, side seal (10) And the inner seal line of the lower shoulder seal (13) is 28 °, the side seal (10, 10 '), the side seal (40, 40') and the tip seal (43) are respectively A bag with a spout having a width of 5 mm, a maximum width (W2) from the inner seal line of the lower shoulder seal (13) of 14 mm, and a width from the bottom to the bottom fold (23) of 35 mm was manufactured. The lower shoulder seal (13) is formed with an emboss (15) that protrudes 0.5 mm from the surface of the lower shoulder seal (13) on the inner side with a width of 4 mm from the outer periphery. It is a side seal (10) from the center line (C).

  First, two sheets of raw material on which a half-cut line (47) as an opening means is formed at a predetermined position by a laser light irradiation device are stacked so that the heat seal layer faces each other, and a bottom film having a width of 70 mm is heat sealed on the bottom. It was folded and inserted so that the layer was on the outside. Next, the side seal, bottom seal, and shoulder seal are heated and welded by a heat seal device, and then the heat seal portion is cooled by a pair of flat plate molds provided with a cooling mechanism to stabilize the welded portion. It was. The lower shoulder seal part (13) was an uneven mold corresponding to the emboss (15).

Subsequently, the outer periphery was punched into a predetermined shape by a punching device, and a bag (100) with a spout, in which only the upper seal (30) was not sealed, was manufactured.
Example 4
The bag with a spout (100) obtained in Example 2 was filled with 350 ml of contents from the opened upper seal (30), and the upper seal (30) was sealed to obtain a product.
In this product, the position of the spout portion (B) was stable without being bent to the front side or the back side of the bag even when the body portion was gripped.

  Next, the spout (B) is opened from the notch (45) along the half-cut line (47), and the refill container has an inner diameter of 26 mm with the outer periphery of the lower shoulder seal (13) as a guide. The side seal (40) of the spout part (B) was locked to the part. Since the position of the spout part (B) was stable, the spout part (B) could be easily locked.

  When the contents are poured out by tilting the bag, the contents on the barrel side are easily transferred to the spout part (B) because the spout part (B) is opened without being bent. We were able to transfer things smoothly. At that time, the spout (B), its base, or the inside thereof was not bent and blocked during the pouring.

(Comparative Example 1)
An unsealed bag with a spout was produced only in the upper seal (30) by operating in the same manner as in Example 1 except that no emboss was formed on the lower shoulder seal (13).

350 ml of contents were filled from the opened upper seal (30) of the bag, and the upper seal (30) was sealed to obtain a product.
In this product, when the body part is gripped, the side seal (40) of the spout part (B) is inclined to the side seal (10) side, and the spout part (B) is also bent greatly from the base part to the back side of the bag. .

  Next, the spout part (B) is opened from the notch (45) along the half-cut line (47), and the spout part (B) is inserted into the mouth part whose inner diameter of the refilling container is 26 mm. However, since the spout part (B) is bent, its position is unstable and insertion is not easy.

When the contents are poured out by tilting the bag, the spout part (B) is bent so that the tip is closed and the contents do not move to the spout part (B) unless the body part is gripped. It was.
(Comparative Example 2)
An unsealed bag with a spout was produced only in the upper seal (30) by operating in the same manner as in Example 3 except that no emboss was formed on the lower shoulder seal (13).

350 ml of contents were filled from the opened upper seal (30) of the bag, and the upper seal (30) was sealed to obtain a product.
In this product, when the body portion was gripped, the side seal (40) of the spout portion (B) was inclined to the side seal (10) side, and the spout portion (B) was also bent from the base portion to the back side or the front side.

  An attempt was made to lock the side seal (40) of the spout portion (B) to the mouth portion having an inner diameter of 26 mm with the outer periphery of the lower shoulder seal (13) as a guide portion. The spout portion (B ) Was unstable, and could not be easily locked to the spout (B).

  When the contents are poured out by tilting the bag, the spout part (B) is bent so that the tip is closed and the contents do not move to the spout part (B) unless the body part is gripped. It was.

  In the conventional bag with a spout, the present invention provides rigidity to the lower shoulder seal by forming a predetermined emboss on the lower shoulder seal, thereby ensuring the positional stability and openability of the spout portion. Therefore, it is useful as a refilling pouch.
