Description

  The present invention relates to a bag container in which a pipe serving as a drinking mouth is attached to a bag filled with a fluid content such as a beverage.

  For example, liquid nutritional drinks are generally sold in bottle containers, but since the collection rate of bottle containers is not necessarily high, products using bag containers have been increasing in recent years.

  As shown in FIG. 6, such a bag container is formed by attaching a hard plastic pipe member 52 serving as a drinking mouth to the upper part of a plastic film bag 51 vapor-deposited on aluminum. The part is sealed with a screw-type cap 53.

  The cap 53 is connected to the main body 54 of the pipe member 52 through a connecting portion, and when opening the bag container, the cap 53 is twisted to break the connecting portion, and the cap 53 is turned and removed. It has become. Thereby, since the trace of opening remains, foreign matter mixing etc. to a drink are prevented and safety | security is ensured.

  In the beverage filling process into the bag container, the cap 53 cannot be removed from the pipe member 52, so that the beverage is poured into the bag 51 from the opening before the upper end of the bag 51 is sealed. Thereafter, the pipe member 52 is inserted into the bag 51, and the bag 51 and the pipe member 52 are brought into close contact with each other and sealed.

  However, the bag container as described above has a problem that the outer diameter of the cap 53 is small and cannot be turned unless the cap 53 is twisted strongly at the time of opening.

  In addition, the pipe member 52 is expensive and packaging costs increase, and a filling machine equipped with a complicated sealing mechanism must be introduced into a beverage manufacturer's production line, which requires a large capital investment.

  Then, this invention makes it a subject to provide the bag container with a pipe which can be opened easily and can reduce packaging cost and equipment investment.

  In order to solve the above-mentioned problem, the present invention provides a bag container in which a pipe member serving as a flow path for contents is attached to an upper part of a bag filled with contents such as beverages, and a funnel part on the upper part of the main body of the pipe member. Is formed in one piece, the contents are filled into a bag through a pipe member, and the funnel part is thermocompression-bonded and sealed to form a knob part on the flattened funnel part, and the knob part is removed to remove the pipe. The member was opened and opened.

  In this bag container, a pipe member with an integral funnel portion is used, and the contents are filled through the pipe member. Therefore, prior to filling the contents, the pipe member is attached to the bag in advance. In addition, when filling at a beverage maker or the like, it is only necessary to thermo-compress and seal the funnel portion, which can reduce capital investment in the filling process.

  Moreover, since the knob | pick part is formed in the funnel part flattened with this sealing, a knob | pick part becomes a wide thing and can remove a knob | pick part easily and can open it.

  In addition, since a simple molded product without a cap can be used as the pipe member, the cost of the packaging material can be reduced.

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

  The bag container shown in FIG. 1 is for beverages, and has a structure in which a pipe member 2 made of hard plastic such as polypropylene is attached to the upper part of a standing bag 1 made of a plastic film deposited with aluminum. Yes.

  As shown in FIG. 2, the pipe member 2 is integrally provided with a funnel portion 4 having a large diameter toward the upper part in an upper part of the pipe-shaped main body 3 in a state before filling with a beverage. Yes. A constricted portion 5 is formed between the main body 3 and the funnel portion 4 of the pipe member 2, and a retaining piece 6 protruding to both sides is provided at a portion to be inserted into the bag 1 of the main body 3.

  In the step of making the bag 1 of such a bag container, the bottom film is folded between the lower portions of the two superposed surface films, and the main body 3 of the pipe member 2 is sandwiched between the upper portions of the surface films. The film 1 is thermocompression-bonded along the both sides from the bottom of 1, and the film is thermocompression-bonded to the pipe member 2 at the top of the retaining piece 6 to cut the outer periphery of the bag 1 into a predetermined dimension.

  On the other hand, in the step of filling the bag 1 with the beverage by the beverage manufacturer, the surface films on both sides of the bag 1 are separated by the suction tool 10 as shown in FIG. 2, and the air is transferred from the funnel portion 4 of the pipe member 2 to the bag 1. Inject and inflate bag 1.

  Next, as shown in FIG. 3, the beverage ejected from the nozzle 11 of the filling machine is poured into the bag 1 from the funnel portion 4 of the pipe member 2 through the main body 3. At the time of filling, since the funnel portion 4 is greatly opened, it is not necessary to position the nozzle 11 with high accuracy.

  Subsequently, as shown in FIG. 4, after the beverage has been injected, the funnel portion 4 is sealed by thermocompression bonding, and the funnel portion 4 flattened in a fan shape is cut along the cutting line a. 1 is formed.

  Thus, in the said bag container, since it was supposed that the bag 1 was filled with the liquid via the pipe member 2 which has the funnel part 4, the pipe member 2 is previously attached to the bag 1 before filling of a drink. In addition, when filling at a beverage maker, it is only necessary to heat-press and seal the funnel portion 4, eliminating the need for a filling machine having a complicated mechanism, and reducing capital investment in the filling process.

  Moreover, since the simple molded product without a cap can be used as the pipe member 2, the cost of a packaging material can also be reduced.

  And since the picking part 7 of the pipe member 2 has a wide width | variety in the bag container sealed in this way, just by lightly twisting the picking part 7, as shown in FIG. And can be easily opened.

  When opened in this way, the main body 3 of the opened pipe member 2 becomes a drinking mouth, and the drink can be directly taken from the bag container as in the conventional cap type.

  In the above embodiment, a bag container for beverages is exemplified. However, a bag container provided with such a pipe member 2 is not only a liquid medicine such as a liquid medicine, a liquid seasoning for refilling, but also a powder detergent. It can also be used for packaging of powdered products such as
