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

FIG. 1 is an overall view of a packaging container according to an embodiment of the present invention, showing a cap portion of the packaging container in an opened state. FIG.
FIG. 4 is a cross-sectional view showing a state where the cap portion of the packaging container is mounted in the embodiment of the present invention. FIG. 3 is a cross-sectional view showing the cap container in the opened state in the embodiment of the present invention.

As shown in the figure, the cap 50 is bonded to a predetermined position on the top wall 12, for example, a position along the horizontal wall at a position close to the boundary line L1 between the top wall 12 and the front wall 18. It is attached by an attaching method such as fusion.
The cap portion 50 includes a substantially rectangular cap base 51 and a cap lid 52, and a spout hole 31 (a cap base inner region) set at a predetermined position on the top wall 12 includes a punch hole. An outlet 21 is formed.

Further, a pull tab 15 is attached from the front side of the packaging material so as to cover the spout 21 in the inner region of the cap base of the cap portion. The pull tab 15 is made of aluminum foil (foil) and has a barrier layer having gas barrier properties, an outermost layer made of polyethylene resin or the like coated on the surface of the barrier layer, and a polyethylene resin coated on the back surface of the barrier layer. And the like. The pull tab 15 has a larger area than the spout 21, and covers the periphery of the spout 21 when attached to the packaging material.
An inner tape (not shown) is attached from the back side of the packaging material on the top wall 12, and is sealed with the pull tab 15 and the periphery of the spout 21. At this time, the front side of the pull tab is simultaneously fixed to the inner side of the cap lid.

Therefore, since the front side of the pull tab is fixed to the inner side of the cap lid by pulling up the cap lid from the packaging container body 10, the pull tab 15 is also peeled off at the same time to break the inner tape. Then, the spout 21 is opened, and the packaging container 10 can be opened. Then, the lips can be put on the cap body and the liquid food can be directly drunk.

Further, by tilting the packaging container 10, the liquid food can be poured from a spout 21 into a container such as a glass (not shown).

The packaging container body 10 is formed by molding a packaging material. For this purpose, a fold is formed in the packaging material in advance, and the packaging material is bent along the fold to form a prototype container. Subsequently, a predetermined molding process is performed on the prototype container to form a packaging container body 10 having a final shape. The wrapping material is made of a laminate having flexibility, and has a paper base (not shown), an outermost layer (not shown) made of polyethylene resin or the like coated on the surface of the paper base, and a back surface of the paper base. A barrier layer (not shown) having a gas barrier property, and an innermost layer (not shown) made of polyethylene resin or the like coated on the back surface of the barrier layer.

Next, the process of forming the spout will be described step by step. FIG. 4 is a process sectional view showing a process of forming a spout in the embodiment of the present invention. FIG. 5 is a process plan view showing a process of forming a spout in the embodiment of the present invention.

In step P1, the spout 21 is punched.
Then, in the process P2, the inner seal device 85
The inner tape 86 is attached from the back side of the packaging material 81. Subsequently, in step P3, the pull-tab sealing device 87 sticks the pull-tab 15 from the front side of the packaging material 81. The cap portion 50 is formed by depositing a resin on a cap tape 82 (not shown) by injection molding, and in a fourth step P4, the cap portion 50 is separated from the cap tape 82 by a cutter (not shown). The packaging material 81 is adhered from the front side by a sealing means such as resistance heating, induction heating, or ultrasonic wave. At this time, the surface side of the pull tab is simultaneously fixed to the inner surface side of the cap lid by a fixing material 90 such as glue.

It should be noted that the present invention is not limited to the above-described embodiment, but can be variously modified based on the gist of the present invention, and they are not excluded from the scope of the present invention. For example, the surface side of the pull tab is fixed to the inner surface side of the cap lid is resistance heating, induction heating,
It can also be implemented by ultrasonic waves or the like.

[0019]

As described above in detail, according to the present invention, the cap for covering the spout formed on the top of the packaging container surrounds the spout and is fixed to the top. It comprises a base and a cap lid for covering the spout, and the cap base and the cap lid are rotatably joined. And the spout portion comprises a pull tab adhered over the spout from the front side of the packaging container, and an inner tape adhered over the spout from the back side of the packaging material, and the pull tab comprises Since the front side is fixed to the inner side of the lid, the front side of the pull tab is fixed to the inner side of the cap lid by pulling up the cap lid from the packaging container main body 10, The pull tab 15 is also peeled off at the same time to break the inner tape, open the spout 21, and open the packaging container 10. Since the cap body can be easily opened with a single operation, the operation is easy, and the lips can be comfortably applied to the cap body and the liquid food can be directly consumed. Further, since the front side of the pull tab is fixed to the inner side of the cap lid, the cap lid itself is stably fixed to the packaging container, so that the cap lid can be inadvertently opened at the store during the distribution process. It is safe because there is no damage, and it also protects against external force such as vibration applied to the packaging container during distribution. Further, since the spout is opened at the same time as the cap lid is pulled up, the fact that the cap lid is opened by mischief can be immediately judged, so that there is an effect as so-called tamper evidence.
