The sealing film (30) is attached to the lower surface of the flange (120) of the spout (100) as shown in FIG. The spout (100) in which the spout hole is sealed by heat sealing or bonding with an adhesive by a heat sealing method or an insert injection molding method is poured into the spout mounting hole (23) of the liquid paper container (20). The outlet cylinder (110) is inserted, and the upper surface of the flange (120) is thermally fused or adhered to the lower surface of the peripheral portion of the plug mounting hole (23) of the liquid paper container (20) so as to project therefrom. Attached).

[0010] The constituent members of the spout plug of the present invention include:
It comprises a cap, a spout, and an opening cylinder provided with an opening blade at the lower end. Next, the structures of these constituent members will be described in detail.

First, the cap (200) according to the first and second aspects of the present invention, as shown in FIGS.
It is composed of a top plate (210) and a peripheral wall (220), and a threaded portion (221) with a spout is provided on the inner peripheral surface of the peripheral wall. A guide inner cylinder (230), which is formed in a spiral shape with a cylindrical body and usually corresponds to a plurality of guide slopes (231), is vertically provided. The cap according to the third and fourth aspects of the present invention is a normal cap including a top plate and a peripheral wall, and a threaded portion with a spout provided on an inner peripheral surface of the peripheral wall.

Next, the spout (100) according to the first and second aspects of the present invention, as shown in FIGS.
A spout cylinder (110) is erected on the inner peripheral edge of the flange (120). A threaded portion (111) with a cap is provided on the outer peripheral surface of the spout cylinder (110), and the inner peripheral surface is provided. Is provided with a plurality of vertical grooves (112) having usually eight locking portions (113) below. The spout according to the third and fourth aspects of the present invention has a spouting tube erected on the inner peripheral edge of the flange, and a threaded portion with a cap is provided on the outer peripheral surface of the spouting cylinder. Accordingly, a plurality of vertical grooves having locking portions below are provided on the inner peripheral surface of the discharge tube. The spouts according to the second and fourth inventions include:
The sealing film is heat-sealed or bonded to the lower surface of the flange.

Next, as shown in FIGS. 1 (a) to 1 (d), the opening cylindrical body (130) according to the first and second inventions has a spout vertical groove (112) above the outer peripheral surface. There are usually provided a plurality of sliding projections (131) for sliding on the inner peripheral surface, and the inner peripheral surface is slidably in contact with the guide slope (231) of the cap.
A plurality of guide slopes (132) of the book are formed correspondingly, and an opening blade (140) is provided at the lower end. Also, the third
And the opening cylinder according to the fourth invention is provided with an opening blade at the lower end, and if necessary, above the outer peripheral surface,
A plurality of sliding projections are provided to slide in the vertical groove of the spout.

The opening blade (140) vertically extending from the lower end of the above-mentioned opening cylinder (130), as shown in FIGS. 1 (a) and 1 (b), moves upward from the pointed head (141). This is an opening blade having a plurality of push-slope slope frames (142) that open radially. The opening blade first punches a hole in the sealing film with a pointed head, and then breaks the sealing film with a plurality of push-rupture slope frames that open radially upward to open the container. For this reason, unlike a conventional triangular or serrated opening blade, as shown in FIG. 7, it is necessary to provide a notched blade portion (143) so that a broken piece (31) of the sealing film (30) does not fall. There is no.

[0015] The cap, spout,
The opening cylinder provided with the opening blade at the lower end is made by injection molding using a thermoplastic resin such as polyethylene or polypropylene. Then, the sliding protrusion on the outer peripheral surface of the opening cylinder is fitted into the vertical groove of the spout, the opening cylinder is inserted inside the spout so as to be slidable up and down, and the cap is screwed onto the spout to cap. This is to produce a spout plug with a built-in opening blade according to the present invention. Note that the sealing film is a laminated film that can be broken by an opening blade, and forms a polyolefin layer on the front and back of an aluminum foil, for example.

When the liquid paper container having the spout plugs with the built-in opening blades of the first and second inventions of the present invention protruding from the top is rotated up to remove the cap, the liquid paper container is raised as shown in FIG. The guide slopes (231) on the outer peripheral surface of the guide inner cylinder (230) vertically hanging from the top plate (210) of the cap (200) shown in FIGS. 1 (a) to 1 (c) are shown in FIGS.
The guide slope (13) on the inner peripheral surface of the opening cylindrical body (130) shown in FIG.
2), the opening cylindrical body receives a force in the direction of rotation opposite to the rotation direction of the cap, but the sliding projection (131) on the outer peripheral surface of the opening cylindrical body is shown in FIGS. 2 (a) and 2 (b). As shown in FIG. 6, the opening cylindrical body descends along the vertical groove because it is in sliding contact with the vertical groove (112) provided on the inner surface of the spout (110) of the spout (100) shown in FIG. And the opening cylinder (14
The sealing film (30) is broken by an opening blade (140) connected to the lower end of (0), and the liquid paper container (20) is opened.
Further, the descending opening cylinder (130) is disengaged from the guide slope (231) of the cap where the guide slope (132) rises, and the locking portion (113) below the vertical groove (112) of the spout (100). The sliding projection (131) comes into contact with the slider and stops. In addition, the liquid paper container having the spouting port with the built-in opening blade according to the third and fourth aspects of the present invention protruding from the top is used when the cap is removed and inserted into the spout inside when used. The cylinder is pressed down with a finger, and the sealing film is broken by an opening blade provided continuously at the lower end of the opening cylinder to open the liquid paper container.

As shown in FIG. 6, a liquid paper container (20) having a spout plug (10) containing an opening blade of the present invention projecting from a top inclined plate (21) is provided with a cap (200).
When the container is removed and the container is opened, the opening cylinder (130) protrudes into the container. The opening blade (140) provided at the lower end of the opening cylinder is provided in FIGS. 1 (a) and 1 (b). As shown, the container has a plurality of crushing slope frames (142) that open radially upward from the pointed head (141), and is not as sharp as a conventional triangular or sawtooth-shaped opening blade, and is a container after use. Even if the hands touched the opening blade during disassembly and separation and recovery, there was no injury to the hands or the like with the opening blade.

[0018]

As described above, according to the liquid paper container of the present invention provided with a spout having a built-in opening blade, the opening blade provided at the lower end of the opening cylinder has a plurality of push-ruptures which open radially upward from the pointed head. It has a beveled frame, and compared with conventional triangular teeth or a saw-toothed opening blade, when the container is disassembled for separate collection after use, the hand etc. There is no danger of hand injury when touching.
