Therefore, when the bellows part 3 is in an unloaded state, the posture of the bellows part 3 is reduced when the pouring cylinder part 4 is lowered from this state with the pouring cylinder part 4 placed in the raised position. . Moreover, when a lateral load is applied to the dispensing cylinder part 4 and tilted, as shown in FIG. 6, the bellows part 3 on the side where the dispensing cylinder part 4 is tilted contracts, and the dispensing cylinder part 4 is tilted. When the opposite side extends and the load is removed, the initial state of FIGS. 2 and 3 is restored.

The extraction cylinder part 4 is a cylindrical member having a general shape except that it is connected to the bellows part 3, and as described above, the annular connection part 20b is connected to the innermost main annular part 20 of the bellows part 3. And a cutter part 4b provided at the lower part of the cylinder part 4a.
The upper portion of the cylindrical portion 4a is formed to protrude upward from the connecting portion 20b of the bellows portion 3.
The cutter portion 4b is formed in a shape in which the lower end portion is cut obliquely and the tip end side of the lower end is pointed, and the cutting direction is inclined obliquely downward toward the attachment portion 7 side. The lower end portion of the cutter portion 4b is disposed in the vicinity of a portion directly above the portion where the opening 17 of the opening forming portion 11 of the container body 9 is to be formed. A gap 23 is formed between the inner surface of the bellows portion 3 and the outer peripheral surface of the extraction tube portion 4.

One end of the attachment portion 7 is connected to the side portion of the base portion 2, and in this embodiment, the attachment portion 7 is connected to the peripheral side surface of the base portion 2 opposite to the one end side of the container body 9 (right side in FIG. 2). The container body 9 is formed to extend to the other end side (left side in FIG. 2). The attachment portion 7 is provided with a pair of overhanging portions 7 a disposed in a cantilever manner along the surface of the container body 9.
The overhanging portion 7a is substantially equal to the thickness (height) of the base portion 2, and is arranged in parallel with a predetermined interval on the peripheral side surface of the base portion.
The holding portion 8 includes a pair of holding wall portions 8b that connect the distal end portions of the pair of projecting portions 7a and extend upward, and a placement portion 8a that is positioned on the base end (lower) side of the holding wall portion 8b. ing. The mounting portion 8a is formed in a semicircular arc shape that is recessed downward, and the holding wall portion is configured so that the cylindrical portion 4a can be held and fixed when the cylindrical portion 4a of the dispensing cylinder portion 4 is placed on the holding portion 8. Locking portions are formed on both inner surfaces of the tip end side of 8b. The interval between the locking portions is formed slightly narrower than the diameter of the cylindrical portion 4a.
The position where the mounting portion 7 is disposed needs to be a position where the cylindrical portion 4a is accommodated between the holding wall portions 8b when the dispensing cylinder portion 4 is tilted.

The lid connecting piece 5 has a thin plate shape that is connected to the holding portion 8 and extends to the other end side (left side) of the container body 9, and is disposed along the upper surface of the container body 9. A lid member 6 is coupled to the distal end side of the lid coupling piece 5 via a hinge 10 formed by a thin portion. The position where the hinge 10 is formed is such that when the lid member 6 is folded back via the hinge 10 with the dispensing cylinder portion 4 tilted and held by the holding portion 8, the lid member 6 is turned to the tip of the cylindrical portion 4 a. That is, it is formed at a position where the dispensing opening 4c is located.
The lid member 6 is formed with an annular annular rib 6a on the plate material, the outer diameter of the annular rib 6a is substantially equal to the inner diameter of the cylindrical portion 4a, and the annular rib 6a is fitted into the dispensing opening 4c of the cylindrical portion 4a. It is formed as follows. The annular rib 6a is formed at a position where the lid member 6 is bent at 90 degrees with respect to the lid connecting piece 5 by the hinge 10, and the lid member 6 is erected and the dispensing cylinder portion 4 is tilted. The rib 6a is provided so as to be positioned in the extraction opening 4c of the cylindrical portion 4a.

As shown in FIG. 1 and FIG. 2 and the like, the pouring tool 1 is molded by injection molding in a state where the base 2, the lid connecting piece 5 and the lid member 6 are substantially on one plane.
In the state where the base 2 is welded to the container main body 9 and the pouring tool 1 is attached to the container main body 9, the lid member 6 is arranged along the container main body 9 as shown in FIGS. The lid member 6 is then closed for product shipment.
The closing operation of the lid member 6 rotates the dispensing cylinder portion 4 toward the lid member 6 with the hinge 10 as a rotation axis. When the dispensing cylinder part 4 is rotated about 90 degrees from the standing (upright) posture and shifted to the inverted state, it comes into contact with the mounting part 8a of the holding part 8 and is held between the pair of holding wall parts 8b.
At this time, as shown in FIG. 4, the bellows portion 3 is contracted on the side where the lid member 6 is provided and is extended on the opposite side. Then, the lid member 6 is bent by the hinge 10, the annular rib 6a of the lid member 6 is fitted into the dispensing opening 4c of the cylindrical portion 4a, and the lid member 6 locks the dispensing opening 4c. Thus, the packaging container is shipped in a state where the dispensing cylinder portion 4 is tilted and held by the holding portion 8 and the lid member is closed.

  When the drinker drinks a drink, he puts his finger on the lid member 6 to open the lid member 6 and unlocks the cylindrical portion 4a of the dispensing cylinder portion 4 from the holding portion 8 and the elasticity of the bellows portion 3 Due to the return force, the dispensing cylinder portion 4 is rotated from the tilted state to the upright standing posture (FIGS. 1 to 3). At this time, the elastic restoring force of the bellows portion 3 is obtained by returning the stretched and deformed portions of the main annular portion 20 and the sub-annular portion 21 to their original shapes.

When the container main body 9 is opened, the dispensing cylinder portion 4 is in an upright state, and the tip (lower) end portion of the cutter 4b is located immediately above the opening forming portion 11, as shown in FIG. The sucker pushes down the dispensing cylinder part 4, whereby the tip of the cutter 4 b of the dispensing cylinder part 4 breaks through the circular thin wall part to form the opening 17. Since the tip of the cutter 4b is formed with a small gap with the opening forming portion 11, the pushing stroke can be reduced when the opening 17 is formed. Moreover, since the opening 17 is formed only by pushing in the extraction cylinder part 4, a target (opening) is not removed.
At the moment when the opening 17 is formed, the inside of the container body 9 communicates with the inside of the gap 23 of the bellows portion 3, and at this time, even if the beverage inside the container body 9 is about to overflow, the overflowing beverage will enter the gap 23. The intrusion to the extraction cylinder part 4 side is reduced, and the outflow from the extraction cylinder part 4 is prevented or suppressed.

In forming the opening 17, the bellows portion 3 shrinks as a whole when the dispensing tube portion 4 is lowered, but as shown in FIG. 7, a part of the main annular portion 20 and the sub annular portion 21. Stretches (sometimes stretches). In FIG. 7, the innermost main annular portion 20 and the sub-annular portion 21 extend, but the inner annular portions 20 and 21 do not necessarily extend. In addition, the plurality of main annular portions 20 and sub-annular portions 21 may expand and contract substantially uniformly.
After the downward pushing force of the dispensing tube portion 4 is released, the dispensing tube portion 4 is caused by the elastic restoring force that the extended portions of the main annular portion 20 and the sub-annular portion 21 return to the original shape. Returns to the raised position as shown in FIG. Since the dispensing cylinder part 4 is supported by the bellows part 3, the direction of the dispensing cylinder part 4 can be tilted in all directions of 360 degrees, and the beverage is dispensed at an angle preferred by the sucker. Can drink from part 4.

In this way, even if the sucker tries to drink the beverage, even if the container body 9 is inadvertently pressed, the lower end of the dispensing tube portion 4 does not go deep into the liquid content of the container. There is no such thing as jumping out of part 4.
When a drinker stops drinking and drinking, the dispensing cylinder part 4 is tilted to the lid member 6 side, the cylindrical part 4a is held by the holding part 8, and the lid member 6 is opened. What is necessary is just to make it fit to 4c.
When the container is not in use, the tip of the cylindrical portion 4 a of the dispensing cylinder portion 4 is covered with the lid member 6, so that foreign matters such as dust do not enter the dispensing cylinder portion 4. Further, since the lid member 6 is integrally formed and connected to the pouring tool 1 by the hinge 10, the lid member 6 is not separated and is easy to use.

As described above, according to the present invention, when the lid member 6 is opened and the engagement with the dispensing opening 4c of the cylindrical portion 4a is released, the dispensing tube portion 4 is brought into an upright posture from the tilted state. It can be returned by the elastic restoring force of the part 3. In such a packaging container, since the extraction cylinder part is held by the bellows part 3, the cutter part can be stably and reliably stabbed into the opening forming part as compared with the conventional stab with a straw. .
Moreover, the connection part of the extraction tool 1 and the container main body 9 is airtight by welding of the base 2, and the connection part of the base part 2 of the extraction tool 1, the connection part 20a of the bellows part 3, and the extraction cylinder part 4 of the bellows part 3 is connected. 20b is airtightly connected by integral molding, and is hygienic without foreign matter entering from the outside.
Since the lid member 6 is hinge-coupled to the lid attachment portion 5 by a thin portion, the lid member 6 is not lost, and the labor of collecting the lid member 6 is saved. When the drinking is interrupted, the pouring opening 4c can be closed by the lid member 6, so that leakage of the contents can be prevented and it is hygienic.

The present invention has been described in detail based on the embodiments with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments, and other modifications can be made without departing from the scope of the present invention. Or it can be changed.
For example, in the said embodiment, although the hinge 10 which consists of a thin part was formed between the cover connection piece 5 and the cover member 6, about the hinge 10, if the plate-shaped cover connection piece 5 elastically deforms, Can be omitted. Further, although the position where the hinge 10 is formed and the position of the annular rib 6a of the lid member 6 have been clarified in the above embodiment, the position can be appropriately changed as long as the lid connecting piece 5 is elastically deformed. is there.

For the holding portion 8, the holding wall portion 8 b is provided, but for the holding wall portion 8 b, a restricting portion that does not cause the dispensing tube portion 4 to stand up against the elastic return force of the bellows portion 3 is formed. The cylindrical portion 4a may be held in cooperation with the lid member 6.
Each of the plurality of main annular portions 20 is formed in the same cross-sectional shape, and each of the plurality of sub-annular portions 21 is formed in the same cross-sectional shape, but the height of the main annular portion 20 and / or the sub-annular portion 21 is the same. And the shape of the step of the bellows part 3 may be changed as appropriate.
