<p>PURPOSE:To facilitate recycling, by forming both bottle body and leg with polyethylene terephtalate and fixing these materials by a fitting means. CONSTITUTION:A bottle body 10 and a leg 20 thereof is made of polyethylene terephtarate already set with heat. The leg 20 is pushed in the bottle body 10 from the bottom 11 and fitted thereto with the upper curved part 21 and the upper protrusion 23 of the leg 20, elastically widened. In this way, the upper round part 21 of the leg 20 is fitted to a groove 13 of the bottle body 10 an the upper protrusion 23 is fitted to the upper edge of the fitting protrusion 14 of the bottle body 10 to fix the leg to the bottle body 10. In this state, the whole bottom 11 of the bottle body 10 is contained in the leg 20. The protrusion 23 at the upper side of leg 20 contacts circularly the outer peripheral face of the bottom 11 of bottle body 10 or it is positioned with a little clearance. A connection aperture is formed between the vertical grooves 14 of bottle body and the round part 21 of leg 20.</p> |
