BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the lantern 11 is composed of a lantern body 12 and a sheet member 13. The lantern body 12 includes a skeleton portion 14 made of polyethylene terephthalate and having a spherical shape, and the skeleton portion 14
It is an integrally molded product composed of a pair of upper and lower annular ring portions 15 formed so as to sandwich the above. The sheet member 13 is a shrink film in which a thermoplastic resin such as vinyl chloride is formed into a thin film. A sheet member 13 is attached to the outer peripheral surface of the frame portion 14 so as to surround the frame portion 14. A pattern 20 called "beer" is printed on the sheet member 13.

Next, a method of manufacturing the lantern 11 having the above structure will be described with reference to FIG. As shown in FIG. 2, first, using polyethylene terephthalate as a raw material, a lantern body 12 composed of a skeleton 14 and a pair of upper and lower muzzle portions 15 is integrally molded using a molding machine (not shown). On the other hand, by using vinyl chloride as a raw material, a shrink film continuously formed into a cylindrical shape having a predetermined wall thickness and inner diameter is produced. Then, the pattern film 20 is printed at the same time while cutting the shrink film, which is continuously formed into a cylindrical shape, with a predetermined length, and the sheet member 13 is produced. At this time, the inner diameters of the upper end opening 16 and the lower end opening 17 of the seat member 13 formed as described above are substantially the same, and the inner diameter is formed larger than the outer diameter of the frame 14 of the lantern body 12. Has been done. Next, the lantern body 12 is placed on a work table or the like with one of the muzzle portions 15 facing downward, and the sheet member 13 is covered from above the lantern body 12. At this time, the sheet member 13 is arranged and held so as to be wrapped around the lantern body 12 at a desired position after being contracted. After that, the lantern 11 including the lantern body 12 and the sheet member 13 loosely fitted on the lantern body 12 is heated by a dryer (not shown) evenly blowing warm air. Then, since the heat deformation temperature of the shrink film forming the sheet member 13 is lower than the heat deformation temperature of the polyethylene terephthalate forming the lantern body 12, the sheet member 13 first has a smaller inner diameter. Begins to contract inward. Then, after heating for a predetermined time, the sheet member 13 will move to the lantern body 1
It is surrounded and attached to the second frame portion 14. Further, in the present embodiment, the predetermined time is set so that the lantern body 12 is heated in the same manner as the sheet member 13 contracts due to heat, but does not reach the temperature at which thermal deformation starts.

As described above, in the present embodiment, the lantern body 12 constituting the lantern 11 is integrally molded with polyethylene terephthalate, so that the lantern 11 is not easily crushed during use after manufacturing, and the lantern 11 is manufactured. The process can be simplified. Similarly, since the sheet member 13 is made of a shrink film, it can be easily wrapped around the lantern body 12 by heat-shrinking it using a heating means such as a dryer. In addition, the sheet member 1 that is wrapped around the lantern body 12
Since 3 is formed in a cylindrical shape and is fitted over the lantern body 12 in a loosely fitted state, the manufacturing process of the lantern 11 can be further simplified and printed on the sheet member 13. The continuous integrated pattern 20 can be formed neatly without dividing the pattern 20.

Furthermore, since the lantern body 12 and the sheet member 13 are manufactured in separate steps, the lantern body 12 having various shapes and the sheet member 13 on which various designs 20 are printed are provided. Can be stored separately.
Therefore, it is possible to quickly manufacture the lantern 11 according to the order by combining the two.

Even in this case, the same effect as that of the present embodiment can be obtained. (2) In the present embodiment, the shape of the lantern body 12 is formed so as to closely resemble the shape of the existing existing lantern 30, but it may be formed into, for example, a columnar body, a prismatic body, or the like. A plurality of slits may be provided radially along the longitudinal direction of the skeleton portion 14. In addition, of the pair of muzzle portions 15,
The lantern 11 may be suspended by hooking a string or the like on the muzzle portion 15 located at the upper portion.

Even in this case, the same effect as that of the present embodiment can be obtained. (3) In the present embodiment, the sheet member 13 is shrunk using the dryer, but if the sheet member 13 can be heated to a temperature at which it can shrink, for example, the lantern body 12
The sheet member 13 may be contracted using a method of covering the sheet member 13 with water and then pouring hot water.

Even in this case, the same effect as that of the present embodiment can be obtained. (4) In the present embodiment, the sheet member 13 is placed on the workbench with respect to the lantern body 12, and the lanterns 11 are individually manufactured. However, for example, a belt conveyor or the like is used to form the lantern body 12. The lantern 11 may be manufactured by the flow work of sequentially enclosing and adhering the sheet member 13 while automatically transporting the lanterns.

In this way, the manufacturing efficiency of the lantern 11 can be surely improved.
