[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spout with a hinge cap for forming a mouth of a container such as paper for storing contents such as milk and juice.

[0002]

2. Description of the Related Art In recent years, various types of containers have been developed for storing and distributing contents such as various drinks and foods. For example, a so-called goebel top sealed carton with a roof top is also widely used. This type of carton has no spout and no spout on the slope of the roof. It is roughly divided. The former requires an operation of peeling off the adhesive portion of the roof portion when opening, and in some cases, peeling cannot be performed reliably, and the reliability of peeling is lacking. For this reason, it can be said that the type in which the opening operation is simple and the latter is provided with a reliable spout is becoming mainstream.

[0003] Various shapes of such a spout are proposed. Above all, 62-13-13
No. 0058, No. 62-143655, etc., the spout with a hinge cap does not fall off at the time of insertion, and further, discharges the contents while holding the removed cap. This is preferable because the operation at the time of pouring is extremely simple.

[0004]

The spout with hinged cap is attached to the carton in the filling machine. In this case, they are aligned by a parts feeder, guided to a supply chute, and set one by one in a carton. However, the conventional spout with a hinge cap has poor slipperiness, and in particular, there is a case where a clogging or the like occurs in the supply chute. Also,
If the machine automatically opens and closes the hinge cap,
There may be a disadvantage that the upper surface of the cap slides and handling cannot be performed reliably. Further, in the case of the conventional spout with a hinge cap, it is not possible to give the cap a unique light-shielding property or to easily color the cap.

In view of such circumstances, the present invention has been devised. The purpose of the present invention is to solve the above-mentioned conventional problems, and to facilitate and surely carry out mechanical operations such as transport and handling of a cap. An object of the present invention is to provide a spout with a hinge cap that allows the cap to have a unique light-shielding property and that can easily color the cap.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a spout with a hinge cap which forms a mouth of a container for discharging contents stored in the container.
A tubular spout body forming a spout for the contents, an opening body that holds the contents in a liquid-tight manner by the time of opening and is removed simultaneously with opening, and detachable from the mouth end of the spout body. A spout molding comprising a cap body that is hingedly connected, wherein the cap body has a mat-like membrane on a top flat surface of the cap.

[0007]

The opening of the spout with hinge cap of the present invention is constructed as described above. At the time of opening, the cap body previously attached is removed, then the pull ring is pulled up, and the opening body is removed from the location of the ring-shaped groove. Cut and remove. Thereby, the contents stored in the container are in a state of being poured out, and after an appropriate amount of contents are poured out, the cap main body is again attached to the spout main body.

As shown in FIGS. 2 and 3, the spout 10 of the present invention has a cylindrical spout body 20 that substantially forms a spout for the contents of the container, and a liquid-tight container contents by the time of opening. An opening body 40 that is held and removed at the same time as opening is provided, and a cap body 60 that is detachably hinged to an outer peripheral end of the spout body.

The spout body 20 has a cylindrical main body 23, and a flange-shaped fixing portion 21 fixed to the container on the outer periphery of the lower base end 23a of the main body 23.
On the other hand, a step portion 25 to which a cap body described later is attached is formed at an upper end portion of the main body 23, and a cap engagement projection 25a protrudes from a part of the step portion 25,
A cap fitting recess 25b is formed.

The lower base end portion 2 of the spout body 20 as described above.
An opening body 40 is formed continuously on the inner periphery of 3a.
The unsealing body 40 is connected to the inner surface of the base of the spout body 20 and seals the bottom before opening, a connecting body 43 erected from the sealing body 41, and a connecting body 4.
3 has a ring-shaped pull ring 47 fixed to the upper end.

The seal body 41 has a substantially disk shape and is removed at the time of opening. Therefore, the seal portion 41 is usually provided at a portion connected to the spout body 20 to facilitate cutting and removing. A ring-shaped groove g is formed. At a part of the inner peripheral edge of the ring defined by the groove g, a connector 43 is erected as shown in the figure. This connector 43 is
The pull ring 47 is connected to the seal body 41 when the pull ring 47 is pulled up at the time of opening, and the shape is usually a plate shape. In addition, from the viewpoint of reinforcement, it is preferable to provide a reinforcing rib 45 having, for example, a triangular prism shape along the center of the inner surface of the connecting body 43 as illustrated. The upper part of the connecting body 43 is connected to a part of the ring-shaped pull ring 47, and the inner diameter of the pull ring 47 is set to a size such that, for example, an index finger can be inserted at the time of opening.
