Abstract

A plastic container for use in receiving product in a hot state the sealing of which creates a negative pressure therein after the product cools, an ovalized portion of the container disposed between a bottom and shoulder having circular cross sections wherein the negative pressure causes a uniform deformation of the ovalized portion allowing the container to remain aesthetically pleasing in appearance.

Claims

1. A plastic container for use in containing a product which is filled therein a hot state and then sealed with the cooling of such product creating a negative pressure in said container, comprising,

a bottom portion having a circular cross section;

a shoulder portion having a circular cross section corresponding to the cross section of the bottom portion, said bottom and shoulder portions in axial alignment;

a neck portion coupled to the shoulder portion having an opening therein so as to allow the ingress and egress of a product contained in the container;

a label portion disposed between the bottom and shoulder portion and coupled therewith, said label portion having an ovalized cross section of approximately the same dimension throughout its length with respect to the circular cross section of the bottom and shoulder portion; and

wherein upon the creation of a negative pressure in the container the label portion is subject to uniform deformation inwardly causing a straightening thereof so as not to distort the appearance of the container.

2. The container in accordance with claim 1 which includes a side wall of the container defined by said bottom, label, shoulder and neck portions with the thickness of the sidewall the thinnest at said label portion.

3. The container in accordance with claim 2 wherein said opening in said neck portion is positioned along the center axis of the container as defined by the axis of the cross sections of the bottom and shoulder portions.

4. The container in accordance with claim 1 wherein said opening is defined by a threaded portion which receives a threaded cap capable of sealing and unsealing said container.

5. The container in accordance with claim 4 which includes a handle means formed in the neck portion which facilitates grasping the container.

6. The container in accordance with claim 1 wherein said opening in said neck portion is positioned along the center axis of the container as defined by the axis of the cross sections of the bottom and shoulder portions.

7. The container in accordance with claim 6 which includes a handle means formed in the neck portion which facilitates grasping the container.
