Description

  The present invention relates to a beverage pouch with a straw for sucking out a filled beverage.

  In recent years, beverage pouches with straws are frequently used as packaging containers for jelly-like beverages. In such a beverage pouch, generally, a cap with a connecting portion is put on the upper end portion of the straw, and when drinking a beverage, the connecting portion is threaded off to remove the cap, and the upper end of the straw is opened to suck the beverage. I am trying to put it out.

  However, such a pouch with a straw covered with a cap requires a lot of force for opening, and there is a problem that it is difficult for elderly people and children to open, and the outer periphery of the straw that is not covered by the cap is distributed. Since it is easy to become unsanitary in a process etc., it is possible to cover a straw with the film of a cover part.

  For example, in Patent Document 1 below, a cover portion that extends upward is formed on one side of the main body portion, and when drinking a beverage, the belt portion provided around the cover portion is pulled to cut out the cover portion, It is described that it can be pushed down and the lower end of the film breaks through the crease of the film below the cover so that the beverage can be sucked out.

Japanese Utility Model Publication No. 56-147250

  However, the beverage pouch described in Patent Document 1 has a problem in that when the cover portion is cut at the time of opening, the band material must be pulled so as to be rotated in the circumferential direction of the cover portion, and the overlapping films are difficult to cut.

  In addition, since the straw must be slid with respect to the main body, the periphery of the straw cannot be completely sealed with respect to the main body. Beverage may leak from

  Then, this invention makes it a subject to provide the drink pouch with a straw which is easy to open, is excellent in the sanitation at the time of drinking a drink, and does not leak a drink.

  In order to solve the above-mentioned problems, the present invention provides a beverage pouch in which a straw for sucking a beverage is covered with a cover portion and attached to an upper portion of a body portion filled with a beverage. Fold the film in half, sandwich the lower part of the crease between the body films on the main body, insert a double-structured straw inside the cover film, and heat the outer pipe of the straw, the cover film, and the body film. Crimp and create a space on both sides of the straw so that the cover can swivel upward with respect to the straw, and make a score line at the bottom of the cover. When drinking beverage, cut the cover at the score line. The inner pipe of the straw was pushed down, and the cover film was pierced at the lower end so that the beverage could be sucked out.

  In this beverage pouch with a straw, the straw is covered with a cover part at the time of distribution, so it is more hygienic than the cap type, and when drinking a beverage, just picking one side of the cover part and pulling it upwards, Without cutting the film, only the cover film can be cut along the score line and the cover part can be easily cut off, so that it is not time-consuming to open.

  In addition, since the outer pipe of the straw can be completely sealed against the main body, when drinking beverage by piercing the cover film at the lower end of the inner pipe of the straw, the beverage leaks from around the straw even if the main body is gripped strongly. I do not put out.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, this beverage pouch is formed by covering a straw 2 for sucking a beverage with a cover portion 3 on an upper portion of a main body portion 1 filled with a beverage. The beverage filled in the main body 1 may be a jelly-like beverage or a liquid food-like beverage in addition to a soft drink such as juice.

  The main body 1 is formed by overlapping two body films 4 and closing the bottom with a bottom film 5, and the cover 3 is formed by folding a single cover film 6. The straw 2 has a double structure in which the inner pipe 8 is slidably inserted into the outer pipe 7, and the boundary between the main body 1 and the cover 3 is between the cuts at both ends along the upper edge of the body film 4. A perforated cut line 9 is provided.

  In the beverage pouch bag-making process, as shown in FIG. 2, the bottom film 5 is folded in two so that the upper part is on the crease side, and the cover film 6 into which the score line 9 has been previously placed is folded on the lower part. The bottom film 5 is sandwiched between the lower parts of the two body films 4, and the lower part of the cover film 6 is sandwiched between the upper parts of the two body films 4. The straw 2 is inserted from above.

  Next, the outer pipe 7, the cover film 6, and the body film 4 of the straw 2 are thermocompression bonded along the upper edge of the body film 4, and the outer peripheral portions of the body film 4 and the cover film 6 are attached to the body portion 1. Thermocompression bonding is performed except for one side. At this time, a semi-circular uncompressed space is formed on both sides of the straw 2 so that the cover 3 can pivot upward with respect to the straw 2.

  Thereafter, when the outlines of the main body 1 and the cover 3 are punched out, the beverage pouch is separated, and the bag making prior to beverage filling is completed as shown in FIG. In this state, one side of the main body 1 of the beverage pouch is open without being thermocompression bonded.

  On the other hand, in the process of filling the beverage pouch with a beverage by a beverage manufacturer, as shown in FIG. 4, the beverage pouch is laid sideways so that the opening side faces upward, and is received by the guide 10, The body film 4 is pulled away by the suction tool 11 and air is put into the main body 1 to inflate the main body 1.

  Next, as shown in FIG. 5, the beverage ejected from the nozzle 12 of the filling machine is poured into the main body 1 from the opening, and when the beverage level reaches a predetermined height, the beverage injection is stopped. Then, as shown in FIG. 6, the end portion facing the opening of the main body 1 is sandwiched between a pair of high-temperature seal bars 13 and the body film 4 is thermocompression bonded. As shown in FIG. To seal.

  In such a sealed state, since the straw 2 is covered with the cover portion 3, the distribution process of delivering the beverage pouch from the beverage manufacturer to the retail store, or when the purchased consumer opens the beverage for drinking , The hygienic state is maintained without dirt and germs adhering to the portion included in the mouth of the straw 2.

  And when a consumer opens, as shown in FIG. 7, either one side of the cover part 3 is picked and pulled upward, the cover film 6 is cut along the score line 9, and the cover part 3 is cut off. At the same time, the inner pipe 8 of the straw 2 is pushed downward to break through the fold portion of the cover film 6 with its sharp lower end so that the beverage can be sucked out as shown in FIG.

  Further, the inner pipe 8 of the straw 2 is first pushed downward to break through the fold portion of the cover film 6, and then one side of the cover portion 3 is pulled upward to cut the cover film 6 along the score line 9. The cover part 3 may be cut off.

  As described above, in the beverage pouch, only the cover film 3 is cut along the cut line 9 without cutting the body film 4 just by picking one side of the cover part 3 and pulling it upward. Can be easily cut off, so it does not take time to open.

  Moreover, since the outer pipe 7 of the straw 2 can be completely sealed with respect to the main body 1, even when the main body 1 is strongly gripped when drinking the beverage by breaking through the cover film 6 at the lower end of the inner pipe 8 of the straw 2, Beverage does not leak from the periphery of the straw 2.

  In the above embodiment, the outer periphery of the cover portion 3 is cut in an arc shape. However, as shown in FIG. 9, the crimped portion of the cover portion 3 is left in an angular shape, and a finger insertion hole 14 is formed in that portion. Then, when the cover part 3 is cut off, a finger may be put on the finger insertion hole 14 and pulled upward.

  Moreover, in each said embodiment, although the width | variety of the cover part 3 was made equivalent to the width | variety of the main-body part 1, the width | variety of the cover part 3 is 0.5 times-1.5 times with respect to the width | variety of the main-body part 1. If it exists in this range, the cover part 3 can be easily cut off at the time of opening.

  In addition, the structure in which the cover portion 3 for covering the straw 2 is provided on the main body 1 in this way is a side gusset type pouch having ridges on both sides in addition to a standing type pouch having ridges on the bottom exemplified in the above embodiment. Can also be applied.
