Description

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

"Prior Art" Thin, large-sized bottles made of saturated polyester or the like are known, which are made by forming a tubular material as an intermediate product in advance and biaxially stretching the tubular material.

``Problems to be solved by the invention'' The large bottles mentioned above are preferably formed by biaxial stretching in order to increase the strength of the bottle and to save materials, but as the stretching rate increases, the walls of the bottle become thinner. It has the disadvantage that it tends to become elastically deformed as it ages, making 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. In addition, a recess is formed in the bottom wall of the bottle, into which the mouth and neck of another bottle formed in the same size and structure as the bottle can be fitted, and by this fitting, the outer periphery of the bottom wall of the upper bottle becomes the lower bottle. It is convenient to stack multiple bottles by placing them on the top of the shoulder of the bottle, but in the case of thin, large bottles, the concave part of the upper bottle and the shoulder of the lower bottle cannot withstand the weight of the upper bottle, causing elastic deformation. As a result, I was unable to stack multiple bottles.

In this case, a handle is attached to the thickest part of the large, thin-walled bottle formed by biaxial stretching, and a leg base with a recess is fitted to the bottom of the bottle body. When stacking, the upper bottle is supported by the handle and the upper surface of the shoulder via a footrest, and thin, large bottles are difficult to hold because they are easily elastically deformed, and it is also difficult to stack multiple bottles. This eliminates the drawback that it cannot be used.

"Means for solving the problem" A handle 6 having a substantially elliptical or rectangular shape having a longer diameter shorter than the outer diameter of the shoulder part 4 of the bottle body is provided at the lower part of the neck part 5 of the bottle body, and the lower surface of the handle and the shoulder part 4 are provided. A rigid foot stand 9 is fitted to the outer peripheral surface of the lower end of the body of the bottle body, and a recess is formed in the center of the lower surface of the bottom wall of the foot stand. The upper part of another bottle body formed in the same size and the same structure can be fitted into the recess, and when the upper part of another bottle body is formed in the same size and the same structure, the lower surface of the bottom wall of the pedestal surrounding the recess is on the upper surface of the shoulder of the other bottle main body, and the lower surface of the recess is One part is formed to be supported on the upper surface of another bottle main body handle 6, respectively.

"Function" The bottle can be lifted and moved by the handle 6 protruding from the mouth and neck. Further, when a plurality of bottles are stacked by fitting the upper bottle recess into the upper part of the lower bottle, the weight of the upper bottle is supported by the handle and shoulder of the lower bottle.

"Example" 1 is a bottle body. The bottle body is, for example, made by biaxially stretching a cold parison made of saturated polyester resin, and has a neck part 5 protruding from the upper end of a body part 3 that stands up from the periphery of a bottom wall 2 via a shoulder part 4. It is something that A cap 8 is screwed onto the mouth and neck. The bottom wall is bulged downward in a spherical shape to increase the stretching rate. Incidentally, since the neck of the cold parison is not stretched and becomes the neck of the bottle, the neck of the bottle is much thicker than the body and the bottom wall.

At the bottom of the mouth and neck part 5, there is a handle 6 having a substantially oval or rectangular shape having a major axis shorter than the outer diameter of the bottle shoulder part.
be attached. An appropriate gap is provided between the lower surface of the handle and the shoulder of the bottle to facilitate lifting of the handle. The handle may be provided with through holes 7, 7 for finger insertion, as shown by the two-dot chain line.

A leg stand 9 is attached to the outer periphery of the lower end of the torso. The footrest has a cylindrical portion 10 fitted from the periphery of the bottom wall to the lower end of the trunk.
In the illustrated example, the handle fitting wall 12 is extended from the lower end of the cylindrical portion 10 via the inwardly projecting portion 11.
erect, the inward flange-like part 13 to be placed on the upper surface of the handle protrudes from the upper end of the fitting wall, and the cap fitting peripheral wall 14 is raised from the inner peripheral edge of the flange-like part, and the cap fitting peripheral wall 14 is raised from the upper end of the fitting peripheral wall. In this example, a support plate part 15 is provided to support the bottom wall of the bottle body, but in short, a recess is formed in the center of the bottom wall, and a support plate 15 of the same size and the same size as the bottle main body 1 is placed in the recess. It is possible to fit the upper part of another bottle body formed in the structure,
At the time of fitting, the lower surface of the bottom wall portion of the pedestal surrounding the recess is on the upper surface of the shoulder of the other bottle body, and a part of the lower surface of the recess is on the handle 6.
They may be formed so as to be supported on the upper surface.

``Effect of the invention'' Because the handle 6 is attached to the lower part of the neck of the bottle, even if the bottle is large and the body of the bottle is easily deformed elastically when filling with liquid, the handle makes it easy to hold the bottle. Since it is shorter than the outer diameter of the bottle shoulder, the handle does not get in the way when a plurality of bottles are lined up, and since the handle is approximately oval or rectangular, it is easy to hold. In addition, since a rigid pedestal is fitted to the bottom of the bottle body, the bottom of the bottle can be strengthened.Furthermore, a recess is formed in the center of the bottom wall of the pedestal, and the same size and structure are formed within the recess. The upper part of the bottle body can be fitted, and when the fitting is done, the lower surface of the bottom wall portion of the pedestal that surrounds the recess is connected to the upper surface of the shoulder of the other bottle body, and a part of the lower surface of the recess is connected to the upper surface of the handle of the other bottle body, Since they are formed so that they are each supported, the weight of the upper bottle can be divided and supported by the handle and shoulder of the lower bottle via the rigid footrest, and the bottle body is thin and easily deforms elastically. Despite this, multiple bottles can be stacked, and furthermore, the lower surface of the bottom wall of the base surrounding the recess is formed so that it is supported by the upper surface of the shoulder of the other bottle bodies when stacking multiple bottles. , the upper bottle can sit better.
