Abstract

PURPOSE:To manufacture a very strongly heat-bonded cylindrical vessel without any wrinkle on the part of hot gluing by a method wherein the zone of hot gluing between the peripheral rim of an upper end plate and the upper outer peripheral surface of a cylindrical side wall is divided into plural parts to effect hot gluing in respective divided zone while the hot gluing of the final divided zone is effected by inserting a jig for hot gluing through a bung hole formed on the upper end plate. CONSTITUTION:The hot gluing zone of an upper end plate 4 to be heatbonded to one end of a cylindrical side wall 3 is divided into four parts and hot gluing is effected in every divided zones sequentially. zones, except the zone 11, show the zones to be heat-bonded while the zone 11 shows a sealed part whose hot gluing is finished already. The hot gluing of the finally divided zone is effected by inserting a receiving plate through a bung hole 5, formed on the upper end plate 4, as a heat bonding jig while abutting a hot plate from outside against the receiving plate to heat and weld the bonding zone, thereafter, the receiving plate is taken out of the bung hole 5. The divided zones are heat bonded sequentially and the hot gluing of the final divided zone is effected while employing the jig for hot gluing, therefore, not only the generation of wrinkles may be prevented but also the hot gluing may be surely effected by the jig for hot gluing which consists of only the receiving plate and hot plate abutted from inside and outside of the bonding zone.

る。(Means for Solving the Problems) That is, the present invention provides a method for manufacturing a cylindrical container that includes a step of thermally bonding a lower end plate to one end of a cylindrical side wall portion and then an upper end plate to the other end. Divide the area that is thermally bonded to the outer peripheral surface of the upper part of the cylindrical side wall into multiple parts, heat bond each divided area, and heat bond the final divided area from the spout formed in the upper end plate using a heat bonding jig. This method of manufacturing a cylindrical container is characterized in that it is carried out by inserting a cylindrical container. The cylindrical side wall used in the present invention may be made of a sheet-like material pasted, but it is usually preferable to use a tube obtained by an inflation method or an extrusion method, and its thickness depends on the size of the container. The diameter varies from 30 to 500 μm, and the diameter is from 100 to 1000+ nm. In addition, those used as the lower end plate or lower end plate are polyethylene,
These include single films such as ethylene-vinyl acetate copolymer and polypropylene, and composite sheets such as nylon/polyethylene and nylon/polypropylene. The lower end plate to be thermally bonded to this can be easily and firmly thermally bonded by applying pressure and heat sealing from the inside and outside of the container using a conventional method. Next, when thermally bonding the top end plate, divide the area that is thermally bonded to the outer circumferential surface of the upper part of the cylindrical side wall into multiple parts, press from inside the container through the part that has not yet been thermally bonded, and sequentially apply pressure to each part. Hot glue the area. When thermally bonding the final divided area, a thermally bonding jig is inserted through the spout formed in the upper end plate, and the area is pressed from inside using the jig to complete the thermal bonding. As a jig for thermal bonding, for example, a plate or the like is used for an arc-shaped heating receiver, and as a thermal bonding means, there are heat seals, impulse seals, ultrasonic seals, etc., any of which may be used6. Embodiments of the invention will be described in detail with reference to the drawings.

The area between the arrows in the figure indicates the area to be thermally bonded, and 11 indicates the seal portion that has been thermally bonded. As shown in Fig. 4, the final divided area is thermally bonded by inserting a plate as a thermal bonding jig into the spout 5 formed in the upper end plate 4, applying heat from the outside, and then heating and fusing it. The plate is taken out from the post pouring port 5.

Rather, as a heat bonding jig, it is possible to securely heat bond the receiver from the inside and outside using a plate and a hot plate.
