Description

[Detailed description of the invention] "Industrial application field" This invention relates to a large, thin-walled bottle formed by biaxial stretching.

"Prior Art" A large bottle made of saturated polyester or the like is known, which is made by forming a tubular material as an intermediate product in advance and biaxially stretching the tubular material.

``Problem that the invention aims to solve'' The large bottle mentioned above should be formed thinner by increasing the stretching ratio in order to increase the strength of the bottle and save material, but this will cause the bottle to deform elastically. This makes it difficult to hold the bottle when filling with liquid. It is not appropriate to attach a handle to such a bottle body because the bottle body will be elastically deformed when lifted by the handle. Furthermore, if a plurality of bottles are formed so that they can be stacked, the lower bottle will not be able to withstand the weight of the upper bottle and will be elastically deformed, causing the upper bottle to fall.

The present invention aims to eliminate the above-mentioned drawbacks and provide a large, thin bottle that allows multiple bottles to be stacked and is easily portable.

"Means for solving the problem" An outward flange 6 is protruded from the lower part of the mouth and neck part 5 of the biaxially stretched thin large bottle body 1, and a rigid leg base 8 is installed on the outer peripheral surface of the lower body part of the bottle body. A recess is formed in the center of the lower surface of the bottom wall of the base, and the bottle body 1 is fitted.
When the recess is fitted to the outer surface of the upper part of another bottle main body formed in the same size and structure as the above, the lower surface of the bottom wall portion of the base surrounding the recess will be on the upper surface of the shoulder of the other bottle main body, and A portion of the lower surface of the recess was formed so as to be supported by the upper surface of the outward flange of the other bottle body. Further, an elastically deformable handle 14 is projected from the upper end surface of the pedestal cylinder by pressing the inner surface of the handle against the outer surface of the bottle body.

"Function" With the handle 14 bent laterally outward against elasticity, the bottle can be lifted and moved by the handle. Furthermore, when a plurality of bottles are stacked up by fitting the recess of the upper bottle into the upper part of the lower bottle, the weight of the upper bottle is supported by the outward flange and shoulder of the lower bottle.

"Example" 1 is a large, thin bottle body made of synthetic resin, for example, formed by biaxially stretching a cold parison made of saturated polyester resin. 2 is the bottom wall of the bottle, 3 is the body, 4 is the shoulder, 5 is the neck that stands up from the inner peripheral edge of the shoulder, 6 is the outward flange provided around the base of the neck, and 7 is the mouth. It is a cap that is screwed onto the neck. The bottom wall 2 is formed to bulge downward in a spherical shape.

A leg stand 8 is fitted to the bottom of the bottle. The pedestal has a cylindrical portion 9 fitted to the bottom of the bottle body erected from the periphery of the bottom wall, and the bottom wall of the pedestal has a cylindrical portion 9 extending from the inner periphery of the inwardly projecting portion 11 to the outwardly facing flange fitting cylinder 12.
and a receiving plate part for supporting the lower surface of the bottom wall of the bottle at the upper end of the cap fitting cylinder. 10 is stretched. When a plurality of bottles are stacked, the inward protrusion 11 of the upper bottle becomes the shoulder of the lower bottle, and the inward flange 13 of the upper bottle becomes the outer flange 6 of the lower bottle.
Each is supported by Further, from the upper end of the cylindrical portion 9, an inverted U-shaped handle 14 is made to protrude. The handle is elastically deformable, and its inner surface is pressed against the outer surface of the body of the bottle body.

``Effect of the invention'' Since the handle 14 is made to protrude from the upper end of the rigid base cylinder, the bottle can be lifted by lifting the handle, and there is no need to hold the bottle body, so biaxial stretching is possible. Even if the bottle elastically deforms and becomes thin enough to be difficult to hold, there is no problem in lifting the bottle, and since the inner surface of the handle is pressed against the outer surface of the body of the bottle body, The handle will not touch other objects and become a nuisance. Furthermore, when a plurality of bottles are stacked, the bottom wall portion of the base surrounding the recess is supported by the shoulder of the lower bottle, and a part of the recess is supported by the outward flange 6 of the lower bottle. , the weight of the upper bottle can be supported by the outer flange and the shoulder of the lower bottle via a rigid footrest, and therefore, even though the bottle body is thin on the inside and easily deforms elastically, You can stack multiple bottles.
