- 3 4 is located at the approximate center of the length of the lower fitting arm 3 2 in the length direction, and the height B from the lowermost end 3 4 to the upper surface of the tip of the projecting piece P of the lower fitting arm 3 2 is the lowermost end of the handle 3. It can be a handle with a structure that is 0.5 to 2.5 times the horizontal distance A from the 34 force to the tip of the lower fitting arm 32.
- the height B is less than 0.5 times the horizontal distance A, when forming the bottle, as shown by an arrow, when the bottle wall 10 is rolled up near the protruding piece P of the lower fitting arm 32 of the handle 3, the protruding piece is used. Since the tip of P disturbs the bottle wall 10 and makes it difficult to get entangled, the handle 3 is easily disengaged from the bottle body 1 and it is not preferable, and if B exceeds 2.5 times A, the handle 3 is grasped during use. The arm is easily deformed by the stress when
- the reason why the bottle body 1 can be securely attached to the handle 3 and the handle can be prevented from being deformed when the handle is attached by this mode is that the bottle wall that wraps the projecting piece P at the front end of the lower fitting arm 3 2 10 is not stretched too much! It is considered that this is because the lower end 34 can be supported at least as shown by the arrow a in contact with the lower surface of the lower fitting arm 32 at the stage. In addition, since the lowermost end 3 4 of the lower fitting arm 3 2 is located almost at the center in the length direction of the handle, an unnecessary dead space where fingers cannot easily enter.
- the handle 3 can be formed with a minimum amount of material without forming a handle.
- the protruding piece is securely wound on the bottle wall, and the handle arm is not deformed by the stress when the handle is grasped during use.
- the container body is made of a polyester resin mainly composed of polyethylene terephthalate
- the handle is a recycled polyester resin mainly composed of polyethylene terephthalate.
- a polyester resin having an intrinsic viscosity of 0.68 or less can be used as a main raw material.
- it is preferable that at least the surface of the handle is crystallized and whitened.
- the polyester resin constituting the container body is mainly a homopolymer of polyethylene terephthalate having ethylene terephthalate as a main repeating unit, but a part of the terephthalic acid component is, for example, isophthalic acid, 2,6-naphthalene dicarboxylic acid. And the like may be blended.
- ethylene glycol or propylene glycol may be used as a part of the ethylene glycol component.
- the polyester resin that constitutes the handle is a molded product such as a bottle of the polyester resin or a regenerated product of pergin material. Usually, the bottle is crushed, and the crushed material (flakes) is washed and dried.
- the polyester resin is a 100% recycled product, which is the most preferable form in terms of effective use of the recycled product.
- the recycled product is not necessarily required to be 100%.
- the molded handle is a regenerated product of a polyester resin containing polyethylene terephthalate as a main raw material, and is composed of a polystyrene resin having an intrinsic viscosity of 0.68 or less, and at least the surface thereof has a spherulite crystal. It is preferably whitened.
- the intrinsic viscosity of the recycled polyester resin constituting the handle is 0.68 or less, Normally, it is 0.65 to 0.55, and if it is 0.69 or more, it becomes white due to the relatively high temperature of around 100 ° C or more and the crystallization does not progress. Energy loss at the time.
- the regenerated polyester resin having a low intrinsic viscosity has a low crystallization temperature, in other words, a temperature increase crystallization temperature after melting and quenching with a decrease in molecular weight.
