ABSTRACT:

FIELD OF THE INVENTION
This invention relates to containers that have an enhanced strength and which when filled and sealed can withstand an increased top load. More particularly this invention relates to cylindrical-like containers that have a sidewall that is substantially devoid of recesses and projections
BACKGROUND OF THE INVENTION
In designing containers for liquid products one objective is to have the filled and closed containers carry the weight of like containers stacked above these containers. The containers will be in cartons or on shrink wrapped platforms. The contact will be carton to carton or platform to closure for shrink wrapped units. Since the filled containers will bear a substantial part of the weight of stacked units, there is a continuing effort to produce containers that have improved strength. The containers require a high burst strength and a high compression strength. Also, the container should not permanently deform from the effect of the compressive load. The result is that the container units can be stacked higher and in the instance where corrugated cartons are used, the cartons can be of a lighter weight. This is the case since a part of the load carried by the carton can be transferred to the containers.
BRIEF SUMMARY OF THE INVENTION
The present invention is directed to containers which can carry greater compressive loads without being deformed. The containers are cylindrical-like containers. Cylindrical-like containers are those that are cylindrical with a set radius, multisided containers which are substantially cylindrical, and oval shapes that are substantially cylindrical shaped containers. The containers have a continuous sidewall, a base closing a first end of the sidewall, and an opening of a second end of the sidewall. The opening can be directly at the second end of the sidewall or it can be at the end of a section extending from the second end of the sidewall. In many instances such extending sections will be substantially conical in shape. Further, the containers have a substantially rigid base surface.
The containers in a preferred embodiment are cylindrical-like and have a sidewall, a base closing a first end of the sidewall and an opening at a second end of the sidewall. The sidewall is devoid of any one of a recess and a projection at a lower part of the sidewall to thereby increase the compressive strength of the container when the container is substantially filled with a liquid. In a further preferred embodiment the full sidewall is devoid of any one of a recess or a projection. In a yet further preferred embodiment the container sidewall has an outward taper from an upper part of the sidewall to a lower part of the sidewall. In still a further preferred embodiment, the container will have a conical-like extension extending upwardly from the second end of the sidewall to an opening.
The result of the container design is a container that has a higher compression strength when substantially filled. The force to a given deflection of the bottle is increased in this bottle design. This increased strength allows for greater stacking of the containers, and cartons of containers. And, if the stacking height is maintained, the amount of corrugate in the packing carton can be decreased. This is the case since some of the compression strength provided by the carton is not needed. A reduction in the amount of corrugate used results in an overall cost savings.
