Since the inner surface of the predetermined bonding location is supported by the anvil 54, it will not deform inwardly, even if a relatively large force is exerted on the plug by the horn 50 of the hating means 48, leadint to the accurate attachment of the plug to the outer surface of the liquie container material.

Description

Detailed Description of the Invention (Industrial Field of Application) This invention relates to a cylindrical liquid container supplied from a liquid container material supplying means, which is filled with liquid from an opening at the other end after closing one end of the material. The present invention relates to a liquid filling and sealing device with a cap attachment device, which is used in a liquid filling and sealing device for sealing an opening at the other end of a liquid container, and includes a cap attachment device for attaching a cap to the outer surface of a liquid container.

(Prior Art) A liquid filling and sealing device that closes one end of a cylindrical liquid container supplied from a liquid container material supply means, fills the liquid from the opening at the other end, and then seals the opening at the other end. BACKGROUND OF THE INVENTION Cap attachment devices used in liquid filling and sealing devices to attach a closure onto the outer surface of a liquid container are already widely used. The material of the liquid container supplied to the conventionally widely used liquid-filled sealed IAH as described above is a rectangular paper tube whose inner surface is coated with a synthetic resin membrane for waterproofing. is common, and the material of this conventional liquid container is fed into the liquid filling and sealing device, where it is first folded to form a flat bottom surface at one end and sealed by heat FfJM, and then After the other open end is filled with a predetermined amount of liquid, the other end is folded to form a gable roof shape and sealed by heat welding. Milk, fruit juice, Japanese sake, and the like are particularly well known as liquids that can be filled into liquid containers shaped like this.

By the way, the conventional spout attachment device is arranged so as to be continuous with the liquid filling and sealing device at the end of the liquid filling and sealing line, and is attached to the outer surface of the liquid container after the liquid filling and sealing operation is completed in the liquid filling and sealing device. A spout is attached to the sloping flat area of the gable M root-shaped portion by heat wJ bonding.

(Problems to be Solved by the Invention) In the spout attachment device arranged as described above for the liquid filling and sealing device, the area on the outer surface of the liquid container to which the spout is to be attached during the attachment operation of the spout. Since it is not possible to support the liquid container from the inner surface, even if the force with which the cap attachment device brings the cap, which has already been heated for thermal welding, into contact with the above area of the outer surface of the liquid container is slightly less than a predetermined value. If it is too large, the area will bend, and as a result, thermal welding of the spout to the area will not be successful. Furthermore, in the above-described conventional spout attachment device, even if the force with which the spout is brought into contact with the region on the outer surface of the liquid container is slightly or smaller than a predetermined value, the spout does not contact the region. Thermal welding does not work properly.

The optimal contact pressure that can reliably thermally weld the cap to the above-mentioned area on the outer surface of the liquid container varies slightly due to various factors, so some defects occur during the attachment process of the cap. It was inevitable.

In order to attach the cap to the above-mentioned area on the outer surface of the liquid container without causing defects, a cap attaching device is installed on the liquid filling and sealing line of the liquid filling and sealing device.
It is also possible to insert the inner surface support member into the opening at the other end of the liquid container whose one end is closed on the line and which has not yet been filled with liquid through the opening at the other end. , which requires significant modification of existing liquid-filled closure equipment.

(Means for solving the problems) This invention was made under the above circumstances, and the purpose of this invention is to:
The present invention does not require any major modification of the existing liquid filling and sealing device, and also allows the attachment of the closure to the above-mentioned area of the outer surface of the liquid container using the closure attachment device without causing any defects. It is an object of the present invention to provide a liquid filling sealing device with a plug attachment device in which the plug attachment device is incorporated into an existing liquid filling sealing device.
