Description

  The present invention relates to a method for producing a pouch with a spout on which a spout for taking out contents is attached, and a pouch with a spout.

  This type of pouch with a spout is a pouch in which a spout is attached to the upper end of a substantially rectangular pouch body, and the spout is a three-side sealed pouch in which both sides and the bottom are heat-sealed and the upper end is open. The pouch body is inserted into the main body, and the upper end portion of the pouch main body is sealed by heat sealing, and at the same time, the pouch main body is fixed. Such spouted pouches are generally mass produced using equipment. For example, as in Patent Document 1 below, a pouch body in a three-side sealed state is sequentially supplied by a belt conveyor so that its upper end (opening side) is the front side. At that time, the pouch body is positioned in the left-right direction by guiding both side edges of the pouch body with a pair of left and right guide walls. By sequentially supplying the pouch body positioned in this way, a spout mounting step and a content filling step are performed, and a pouch with a spout filled with the content is manufactured.

  By the way, in the pouch which does not have a spout, the unusually shaped pouch in which the recessed part opened to a side is formed in the side seal part like the following patent document 2 is proposed. In this pouch, a concave portion is formed when the side seal portion is formed or thereafter, and in any case, the concave portion is already formed in a three-side seal state before the upper end portion is sealed. .

  However, it is difficult to manufacture a pouch with a spout using such a pouch having a recess on the side as a pouch body. That is, assuming that a concave portion is formed in advance on the side portion of the pouch body, when the pouch body is conveyed by a belt conveyor, accurate positioning in the left-right direction of the pouch body is difficult due to the uneven shape of the side portion. Incorrect conveyance is likely to occur due to the shape being caught on the guide wall during conveyance.

  In addition, as described in the following Patent Document 3, a half cut line that crosses the accommodation space is formed to form the spout portion at the corner of the pouch, and the cut line is connected to the half cut line so as to be connected to the half cut line. It has also been proposed that a knob is formed by a cut line at the time of opening to form a spout part. However, this configuration also has no spout, and is a type in which the spout is formed by breaking a part of the pouch rather than using a spout.

  Therefore, the present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a method for producing a spout with a spout having a modified shape suitable for machine production and a pouch with a spout.

  The present invention has been made to solve the above-mentioned problems, and a method for producing a pouch with a spout according to the present invention is a method for producing a pouch with a spout in which a spout is attached to the upper end of a pouch body having a side seal portion. Then, after forming a separating line in the side seal portion for separating the outer region in the side seal portion, the spout is attached to the pouch body in a state where the outer region is not separated.

  In the manufacturing method, the spout is attached without separating the outer region of the side seal portion, although the separation line is formed on the side seal portion, so that the guide wall or the like is used in the same manner as the conventional pouch body not forming the separation line. The spout can be mounted at an accurate position by accurately positioning in the left-right direction.

  In addition, the outer region of the side seal portion may be separated before filling the content, but it is preferable to separate the outer region after filling the content from the spout and attaching the cap to the spout. By separating the outer region after filling the contents, the spout mounting process and the contents filling process can be performed in a series of flows, and can be manufactured efficiently.

  Further, the pouch with a spout according to the present invention is a pouch with a spout in which a spout is mounted on the upper end of a pouch body having a side seal portion, and a separating line for separating an outer region in the side seal portion is a side seal portion. It is characterized by being formed.

  The spout pouch can be shipped after the outer region is cut off, or can be shipped with the outer region left uncut. In the latter case, for example, the outside area may be set as an area for campaign application, and the consumer may apply by separating it after purchase.

  In addition, the side seal part is provided with a hollow non-adhesive region that is not heat-sealed, and the non-adhesive region is provided with an inner display part that is visible only from the inside, and the inner display part is opened by opening the non-adhesive region. It is preferable that the separation line is formed through a non-adhesive region so that it can be visually recognized.

  In this case, since the consumer can see the inner display part only after separating the outer area after purchase, for example, the contents can be sold by displaying “point” or “out” as the inner display part or displaying points. A promoting effect is obtained.

  As described above, by attaching the spout to the pouch body in a state where the outer region is not cut off, positioning of the pouch body in the left-right direction when attaching the spout is the same as a general structure having no separation line. In addition, it can be performed accurately and is suitable for machine production including application to existing equipment. And, by separating the outer area with a separating line after the spout is attached, it is possible to easily manufacture a pouch with a deformed spout, which is easily noticeable at the storefront, and combined with the original bulging shape of the pouch, it has an unprecedented three-dimensional effect Can be produced.

The top view which shows one manufacturing process of the pouch with a spout in the embodiment. The front view which shows the pouch with a spout in other embodiment of this invention. The front view which shows the use condition of the pouch with a spout in the embodiment.

  Hereinafter, a pouch with a spout according to an embodiment of the present invention and a manufacturing method thereof will be described with reference to FIGS. The pouch with a spout shown in FIG. 1 has a pouch body 1 formed in a bag shape capable of storing various contents by heat-sealing the peripheral edges of a pair of front and back sheet pieces, and an upper end portion of the pouch body 1. It is equipped with a spout 2 that is attached and used for filling and taking out the contents.

  The pouch body 1 is a flat pouch that does not have gussets on the bottom and sides, is formed in a substantially rectangular shape that is long in the vertical direction, and its peripheral edge is heat-sealed. In FIG. 1, a region with a large number of dots is a heat-sealed seal portion. That is, the seal portion of the pouch body 1 includes a bottom seal portion 30, a pair of left and right side seal portions 31, and an upper end seal portion 32 to which the spout 2 is attached.

  The pair of left and right side seal portions 31 are formed wider than the bottom seal portion 30 and the upper end seal portion 32, and are formed to have a constant width along the vertical direction. Therefore, the storage space for filling the contents is a vertically long rectangle when viewed from the front. Further, the pair of left and right side seal portions 31 are cut to separate the outer region of the side seal portion 31 into side pieces (outside) from the main portion of the pouch body 1 located inside the cut pieces 40 and 41. Separation lines 50 and 51 are formed. In the present embodiment, the left and right separating lines 50 and 51 are asymmetrical to each other, and the sizes of the separating pieces 40 and 41 to be separated are also different. That is, a separation line 50 is formed in the side seal portion 31 on the right side so as to extend from the upper edge to the lower edge of the pouch body 1 over the entire length of the side seal portion 31. The right-side separation line 50 is not a straight line along the vertical direction, but has a shape meandering to the left and right. More specifically, a pattern is formed by printing on the outer surface of the pouch body 1, that is, the outer surface of the front-side sheet piece, as a front-side display unit 60 (indicated by a two-dot chain line), and cut along the front-side display unit 60. A separation line 50 is formed. In the present embodiment, since a circle or a polygon is drawn as the front side display unit 60, the parting line 50 is partially arcuate or convex (tapered convex) along the circle or polygon. In addition, the left side seal portion 31 is formed with a separation line 51 at a middle portion in the vertical direction so as to form a concave portion that opens to the side by cutting out a part of the side edge of the pouch body 1. ing. The left parting line 51 is also formed along the front display unit 60 in the same manner as that on the right side.

  The separating lines 50 and 51 can adopt various forms such as a half cut that is cut halfway in the thickness direction and various perforations that are discontinuous in places that penetrate in the thickness direction. In any case, it can be cut by hand.

  Here, as a sheet | seat which comprises the pouch main body 1, an outer layer which consists of a biaxially stretched polyester film, a biaxially stretched polyamide film, etc., a low density polyethylene, a high density polyethylene, a linear low density polyethylene, a polypropylene, a metallocene type | system | group, for example A multilayer laminate film with an inner layer made of a heat-fusible resin such as polyethylene is used, and gas barrier properties such as films deposited with inorganic substances such as ethylene vinyl alcohol copolymer, aluminum foil, silicon oxide, etc. What laminated | stacked the film etc. further is suitable, and what laminated | stacked aluminum foil as a gas-barrier film is especially preferable.

  The spout 2 is formed of a heat-sealable synthetic resin (a heat-sealable resin such as polyethylene or polypropylene) on the inner surface of a sheet constituting the pouch body 1 and is generally formed integrally by molding. The spout 2 is attached to the center of the pouch body 1 in the left-right direction. Specifically, the spout 2 is attached by heat sealing so as to be sandwiched between a pair of front and back sheet pieces at the upper end of the pouch body 1. A portion 20, a mouth portion 21 formed so as to protrude from the attachment portion 20 to the outside of the pouch body 1, that is, upward, and a portion 21 that protrudes from the attachment portion 20 to the inside (accommodation space), that is, downward. And an inwardly extending portion 22. The attachment portion 20 has a substantially boat-like shape in cross-sectional view with the thickness in the front-rear direction gradually decreasing from the center to both sides. A cap 23 for sealing the upper end opening is screwed to the mouth portion 21, and a pair of upper and lower rectangular flange portions 25 and 26 are formed on the lower side thereof.

  The pouch with a spout configured as described above can be shipped without separating the left and right separating pieces 40, 41 as shown in FIG. 1, or as shown in FIG. , 41 can be shipped after being separated by the separation lines 50, 51. In the former case, for example, the purchased consumer can cut off the cut pieces 40 and 41 themselves, thereby enjoying the change in the shape of the pouch before and after the cutting. In the latter case, the separation pieces 40 and 41 are separated in advance before shipment or before being lined up at the store, etc., but the separation lines 50 and 51 are formed so that they can be easily separated by hand. By this, an irregularly shaped pouch can be easily formed. In the present embodiment, the separation lines 50 and 51 are formed along the front side display unit 60. Therefore, after separation, a part of the front side display unit 60 becomes the outer shape of the pouch as shown in FIG. Will appear. Therefore, compared with the case of only a general pattern, it is extremely conspicuous in a storefront or the like, and the pattern of the front side display unit 60 can be expressed in three dimensions in combination with the bulge shape inherent to the pouch. Since three-dimensional expression is possible in this way, it is also preferable to print various characters as the front display unit 60 to obtain character products.

  On the other hand, this pouch with a spout inserts the spout 2 into the pouch main body 1 in a three-side seal state with an open upper end to seal the upper end of the pouch main body 1 and fix the spout 2, and then the contents from the spout 2. The cap 23 is attached after filling the pouch. Before the spout 2 is attached to the pouch body 1, the separation lines 50 and 51 are formed on the pouch body 1 in advance by, for example, a die cutter (punching) or a Thomson blade. deep. Then, the pouch body 1 in which the separation lines 50 and 51 are formed is placed on the belt conveyor 100 as shown in FIG. 3 and sequentially supplied to the spout filling process. Also in FIG. 3, like FIG. 1, the portion to which a large number of dots are attached is a seal portion and is placed on the belt conveyor 100 so that the upper end 1a that is open faces the front side. The pouch body 1 is conveyed while positioning in the left-right direction with the guide wall 101 standing upright. Since the separating pieces 40 and 41 are not separated at this supply stage, the guide wall 101 can be accurately positioned in the left-right direction and centered in the left-right direction as in the normal shape, and the pouch body 1 Since the side edge is not uneven, the side edge is not caught and a conveyance failure does not occur. Thereafter, the pouch body 1 is sucked by an unillustrated suction member and the posture is changed to a standing posture in which the upper end portion 1a faces upward, and the spout 2 without the cap 23 is placed in the horizontal direction (width) of the pouch body 1 from above. Direction) The upper end portion 1a is sealed and the spout 2 is attached by being inserted into the center position, whereby the upper end seal portion 32 is formed. Subsequently, the contents of the spout 2 are filled with contents from the spout 2 while being held in a suspended state while being held between the upper and lower flanges 25 and 26, for example, by a holding member (not shown), and the cap 23 is further attached. 1 is completed. As described above, the separation lines 50 and 51 are formed in the pouch body 1 in advance before the spout 2 is mounted, and the existing filling machine or the like is used by mounting the spout 2 without disconnecting the separation pieces 40 and 41. And high speed production.

  In general, the separated pieces 40 and 41 after being separated are discarded, but can be used as, for example, an application ticket for a campaign.

  Alternatively, a hollow non-adhesive region that is not heat-sealed may be provided in the side seal portion 31, and the separation lines 50 and 51 may traverse or longitudinally cut through the non-adhesive region. For example, in FIG. 4 and FIG. 5, the seal portion is shown with a large number of dots, but non-adhesive regions 70 are formed in the side seal portions 31 respectively. In the non-bonding region 70, the pair of front and back sheet pieces are not heat sealed. The non-adhesive region 70 is provided with an inner display portion (not shown) that is not visible from the outside but visible only from the inside. As the inner display portion, characters such as “hits” and “out of” and points can be used for the campaign. These characters and points can be printed by laser printing or the like.

  The right and left side seal portions 31 are each formed with a substantially rectangular non-adhesive region 70, and separation lines 50 and 51 are formed so as to pass through the non-adhesive region 70. The part of the right parting line 50 that passes through the non-adhesion region 70 has an outer convex shape (for example, an arc shape). Therefore, as shown in FIG. 5, when the right-side cut piece 40 is cut and the non-adhesion region 70 is opened, the non-adhesion region 70 is divided into two, and the non-adhesion outer convex portion is formed in the non-adhesion region 70 of the pouch body 1. 71 is formed, and the inner display portion can be seen by opening the front and back sheet pieces of the outer convex portion 71. Further, the left parting line 51 has an inner convex shape (for example, an arc shape) at a portion passing through the non-bonding region 70. Accordingly, when the left side cut piece 41 is cut off, the non-bonded region 70 is divided into two as in the case of the right side, and the cut off cut piece 41 is bonded to the non-bonded portion 41a formed of a part of the non-bonded region 70 and the bonded portion. 41b. And the inner side display part of the non-adhesion part 41a can be seen by opening the sheet piece of the front and back in the non-adhesion part 41a of the cut-off separation piece 41. FIG. In this case, the left cut piece 41 is suitable for use as an application ticket because the inner display portion is formed on itself. As described above, the inner display portion may be formed so as to remain on the pouch body 1 as on the right side, or may be formed so as to be located on the separation piece 41 that is separated as on the left side, and provided on both sides. You may do it. The convex shape is not limited to the arc shape, but may be a rectangle or a triangle.

  In addition, the inner line of the seal portion that divides the accommodation space is also made straight as shown in FIG. 1 and is bulged inward in accordance with the formation of the separation lines 50 and 51 as shown in FIGS. Also good.

  Further, in the above embodiment, the separation lines 50 and 51 are formed on the left and right sides, respectively, but only one side may be formed. Moreover, you may form the several cutting line and cutting piece which became independent up and down in one or both of right and left. Of course, when the non-adhesion region 70 is formed, the shape, number, position, etc. thereof are also arbitrary.

  In the above embodiment, a flat pouch has been described as an example, but a form having a side gusset or a bottom gusset may be used.
