This application claims the benefit of priority under 35 U.S.C. §119(e) of U.S. Provisional Application Ser. No. 60/786,055, filed Mar. 23, 2006, and entitled “LIQUID CONTAINER,” and U.S. Provisional Application Ser. No. 60/892,461, filed Mar. 1, 2007, and entitled “LIQUID CONTAINER.”
This disclosure relates in general to containers and, more particularly, to a liquid container providing enhanced structural integrity.
Various types of containers have been developed for the distribution of liquids to consumers. Liquids stored in these containers may include consumable liquids, such as milk, juice, or water, or may include other types of non-consumable liquids, such as detergents, automotive products, or the like. These containers may be integrally formed from various formulations of thermoplastic resins in order to form a generally thin-walled container having a storage capacity that may include one-gallon, half-gallon, one-quart, and other sizes. For distribution of these containers from the manufacturer to consumer, multiple containers may be stacked together in a crate or other type of mass packaging mechanism.
According to one embodiment of the disclosure, a container includes a base portion, a spout, an annular sidewall portion, an upwardly converging portion, and a handle portion that are integrally formed together. The spout has an associated closure cap that has a first height from the base portion when disposed on the spout. The handle portion has an upper support surface that has a second height from the base portion that is approximately equal to the first height. The handle portion has a generally vertically extending member and a generally horizontally extending member. The generally vertically extending member extends from the annular sidewall to the generally horizontally extending member.
Embodiments of the disclosure may provide numerous technical advantages. Some, none, or all embodiments may benefit from the below described advantages. According to one embodiment, the liquid container may have a handle portion that operates in conjunction with the spout to provide structural support for other items placed upon the liquid container. The spout and handle portion are formed on the container such that downward directed forces may be distributed through the container in a generally even manner.
Other technical advantages will be apparent to one of skill in the art.
A more complete understanding of embodiments of the disclosure will be apparent from the detailed description taken in conjunction with the accompanying drawings in which:
Known implementations of liquid containers are typically stacked together in order to enable distribution from manufacturer to consumer in a relatively efficient manner. The structural design of these containers however, do not provide sufficient structural integrity for stacking one upon another.
Liquid container 10 generally includes a base portion 12, an annular sidewall portion 14, a neck portion 16, a generally hollow handle portion 18, a spout 20, and a closure cap 22. The annular sidewall portion 14 is integrally formed with and extends upwardly from the base portion 12. Neck portion 16 has a generally upwardly converging shape and is integrally formed with the annular sidewall portion 14 and spout 20. The handle portion 18 is integrally formed on the neck portion 16 proximate the rear side 14 b of the annular sidewall 14. The base portion 12, annular sidewall portion 14, neck portion 16, and handle portion 18 together form a cavity for the storage of various types of liquids inside. As will be described in detail below, the handle portion 18 has an upper support surface 38 that may provide structural support for multiple liquid containers 10, one upon another.
Closure cap 22 may be removably secured on the spout 20 for enclosing the contents of liquid container 10. The liquid container 10 may incorporate any suitable type of industry standard closure cap 22. Caps of this nature may be available from Portola, located in Batazia, Illinois. The container 10 as shown has thread-like ridges 24 that are adapted for use with screw-on caps, however, it will be understood that a snap-on removable securing mechanism, or other similarly known removable securing mechanisms may provide a viable alternative.
The handle portion 18 has an upper end 26 and a lower end 28. The upper end 26 is integrally formed with the neck portion 16 proximate the spout 20 and the lower end 28 is integrally formed with the neck portion proximate the annular sidewall portion 14. In one embodiment, the handle portion 18 has a generally hollow shape that may provide a portion of the cavity used for storage of liquid inside.
In one embodiment, the handle portion includes a generally horizontally extending member 18 a and a generally vertically extending member 18 b that are joined together at a relatively perpendicular angle. The upper support surface 38 is formed in the generally horizontally extending member 18 a such that the upper support surface 38 may be generally flat in shape and extend to essentially to a corner formed by the generally horizontally extending member 18 a and generally vertically extending member 18 b.
The generally vertically extending member 18 b extends from the annular sidewall portion 14 to a height above the base portion 12 approximately equal to the height of closure cap 22 when secured on the spout 20.
In another embodiment, base portion 12 may have a number of corners 44 that are each chamfered with a portion of the annular sidewall portion 14. In another embodiment, the chamfered portion of the corners 44 may include ribs 46 for enhanced structural rigidity.
In one embodiment, a gusset 32 may be provided between the spout 20 and the handle portion 18 as best shown in
In another embodiment, a number of generally horizontal ribs 50 may be formed in the upwardly extending cavity 48 to enhance the structural rigidity of the base portion 12. The generally horizontal ribs 50 may exist in any configuration that reinforces the point loading strength of the base portion 12. This optional feature may be particularly useful when several containers 10 are stacked one upon another without the use of slip sheets or other such intermediary devices.
The particular liquid container 10 as disclosed is configured to store approximately one U.S. gallon of liquid. It will be understood however, that a container having other capacities could be constructed using the teachings of this disclosure. The container 10 as best shown in
The liquid container 10 may be constructed of a high density polyethylene (HDPE) plastic material, which is generally “food safe”, for storage of human consumable liquids. However, the liquid container 10 may formed from any suitable plastic material appropriate for the type of liquid it is adapted to contain. Nevertheless, the present embodiment may be formed using conventional blow molding techniques, which are well known to those skilled in the art.
Although an embodiment of the present disclosure has been described using specific terms, such description is for illustrative purposes only. The words used are words of description rather than of limitation. It is to be understood that changes and variations may be made by those of ordinary skill in the art without departing from the spirit or scope of the present disclosure, which is set forth in the following claims. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments disclosed therein.
