Description

The present invention is an opening of a pouch for accommodating liquid or relatively viscous (low fluidity) jelly-like or paste-like contents such as beverages, foods, chemicals, pharmaceuticals, detergents, cosmetics and seasonings. Regarding the spout attached to the part. The present invention also relates to a pouch with a spout to which the spout is attached.

Pouches with spouts that enclose and wrap liquid, jelly-like, and paste-like contents are known.
Filling the pouch with spout is to insert a nozzle into the spout spout and pour the contents. In recent years, the series from supplying the pouch with spout to filling the contents and attaching the cap is fully automatic. A filling device is provided.
As an example of a fully automatic filling device, as shown in FIG. 6, a pouch with a spout is transported to a filling process with a spout locked on a transport rail 30 composed of two rails 30a, and is sent to a filling process. In some cases, the spout is fixed by the holding member 32 as shown, and the cap is attached after filling the contents from the spout.
As a spout for a pouch with a spout used in such a filling device, for example, in paragraph 0028 of Patent Document 1, a plurality of flange portions are arranged on the tubular portion, and the groove width of the groove formed between the flanges is conveyed to the transport rail. It is disclosed to design the size so that it can be inserted into.

It may be provided with a coated coat film or the like.

Next, an example of a state in which the pouch with a spout is handled by a device such as a fully automatic filling device will be described.
The spouted pouch before filling the contents is supplied to the filling device without the cap attached. As shown in FIG. 6, the pouch with a spout is supplied to the filling device in a state where the spout is locked to the transport rail 30 composed of the two rails 30a and the pouch with the spout is suspended. In the transport rail 30, the thickness of the rail 30a and the gap between the rails 30a differ depending on the device. When locking the pouch with spout to the transport rail 30, depending on the thickness of the rail of each device and the gap between the rails, whether to lock at the intermediate portion α of the spout or at the intermediate portion β. Can be selected as appropriate.

The pouch with a spout conveyed to the filling device is then locked by the sandwiching member 32 shown in FIG. 7. The sandwiching member 32 includes a groove portion 32a having a substantially U-shape, and a spout is inserted into and fixed to the groove portion 32a. In the sandwiching member 32, the thickness of the sandwiching member 32, the groove width and the depth of the groove portion 32a differ depending on the device. When locking the pouch with a spout to the sandwiching member 32, depending on the thickness of the sandwiching member 32 of each device, the groove width and the depth of the groove 32a, the pouch may be locked at the intermediate portion α of the spout or the intermediate portion β. It is possible to appropriately select whether to lock with.
The pouch with a spout fixed by the holding member 32 of the filling device is filled with the contents by inserting a nozzle from the spout outlet. After the contents are filled, the spout is capped to complete the product.
The spout according to the present invention has three or more flanges, and includes two or more intermediate portions of a tubular body sandwiched between a transport rail or a holding member. As a result, for example, the transport rail can be transported to the filling process with the transport rail locked to the intermediate portion α, and the sandwiching member can be inserted into the intermediate portion β to be sandwiched at the time of delivery, so that the transfer can be performed smoothly. ..
