Definitions

• This invention is based on a saturated polyester resin material.] 3 Regarding the formed thin-walled field, especially when the bottle circle is under negative pressure, the field is deformed because the wall is thin. To prevent damage.
• Saturated Polyester bottles have recently been noted for the lack of solvent leaching and no toxic gas generation during incineration.
• the bottle is usually stretched biaxially to enhance its mechanical properties and used as a thin bottle.
• the present invention aims to form a lightweight yet tough thin bottle from a saturated polyester resin material, and to reduce the deformation caused by the negative pressure of the bottle circle.
• the regular deformation of the garment made it possible to absorb it positively, so as not to impair the appearance of the bottle, and also to prevent the reticle attachment in the field from being deformed. .
• FIG. 1 is a side view of a thin-walled field made of a saturated polyester resin of the present invention
• FIG. 2 is a cross-sectional view taken along the line [1] of FIG. 1
• FIG. Section I Fig. 4 is a side view of the saturated thin polyester resin thin bottle of the second embodiment
• Fig. 5 is a sectional view taken along the line V-V in Fig. 4.
• the thin bottle 1 of the present invention obtained by biaxially stretching a tubular material made of a saturated polyester resin has a body portion 2 having a bottom wall in order from the bottom, a shoulder portion 3 having a small diameter at the upper end, and Mouth and neck 4.
• the force s forming the cylindrical part 5 between the body part 2 and the shoulder part 3 and between the body part 2 and the shoulder part 3 is deformed like the body part 2 as described later. Since it is not available, use it as a sticking part for a
• the torso part 2 is formed in a polygonal cylindrical part, and the ridge line is
• a vertical plane 7 is formed between the ridges 6
• the top and bottom of the torso 2 each have a small diameter tip
• the upper part of the upper part is connected to the cylindrical part 5 via the annular ridge 10, and the lower part of the lower part is formed.
• the lower end of part 9 has an outer circumference
• this bottom wall 11 has the center toward the center to increase the strength.
• Parts 12 and 13 are formed, and the tongue-shaped parts 12 and 13 stand upright.
• the peripheral wall of the torso 2 has a plurality of substantially elliptical flat walls.
• the center of the ellipse is set as the vertex
• the above thin saturated polyester resin thin bottle is shaped
• the bottle circle becomes negative pressure due to the shrinkage due to the temperature drop.
• the curvature in the circular direction that occurs in the upright plane 7 is deformed according to the ellipse with the center of the substantially elliptical plane as the vertex, and the curvature is the upright plane of the trunk 2. Since it occurs uniformly in all of 7 above, it is preferable in terms of the bottle appearance as a three-dimensional pattern.
• the bottle filled with the liquid is then opened by the consumer, etc. j. If the bottle pressure is increased to atmospheric pressure, the curvature of the upright flat bar 7 becomes the elasticity of the bottle wall. Yo j? Restore to the plane state.
• the ridge 6 is bent so that the strength is not less than the flat part, and the tip of the scat-shaped parts 8 and 9 Since is a tapered cylindrical shape, no deformation occurs similarly. Then, when the standing flat 7 is bent, the circular angle A of the ridge 6 becomes small, and the strength of the ridge increases. Further, the tongue-shaped portions 12, 13 formed continuously from the erecting flat 3 ⁇ 47 extend the same length as the erected flat a7 in the vertical direction. It is possible to bend over a long range, and to cope with the negative pressure of the field. Since the edges of 13 and 13 are curved, stress concentration does not occur at the edges.
• annular ridge 14, 15 is provided on the cylindrical portion 5.
• annular grooves 16 are formed in the cylindrical portion 5 to increase the strength of the bottle wall. Then, letter 7 adhere to cylindrical part 5. Other configurations and operations are the same as those in the above embodiment.
