The invention relates to a container for holding a flowable substance, and more specifically, to a container having characteristics to enhance pouring of a flowable substance therefrom.
It is known to make containers for liquid of plastics material, for example, high density polyethylene. Such containers may be closed by, for example, sealing the opening of the container with a cap, such as a threaded cap that screws onto a mouth of the container. While liquid containers are known, they often exhibit undesirable properties when pouring out the contents. As a flowable substance is poured from a container, a vacuum is created, drawing air into the container to replace the volume of the contents poured out. Typically, this airflow enters the container through the same opening through which the flowable substance is exiting the container. At a certain point, the flow of the flowable substance reaches a point where the substance exiting the container blocks or interrupts the air flow into the container, creating a phenomenon known as “glugging.” Glugging often causes uneven and uncontrollable pouring, leading to splashing, spills, and other undesirable results. Existing containers typically do not exhibit satisfactory performance in enhancing a smooth, controllable flow of contents when poured and reducing glugging.
The present assembly is provided to solve the problems discussed above and other problems, and to provide advantages and aspects not provided by prior containers of this type. A full discussion of the features and advantages of the present invention is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
Aspects of the present invention relate to a container for containing a flowable substance that includes a container body, a substantially elliptical opening in the container body, and a resealable closure affixed over the opening. The container body defines an internal cavity that is adapted to contain the flowable substance therein. The opening is adapted to allow the flowable substance to flow therethrough. The resealable closure is adjustable between an open position, where the flowable substance can flow through the opening, and a closed position, where the closure obstructs the opening to prevent the flowable substance from flowing through the opening.
According to one aspect of the invention, when the closure is in the open position and the container is substantially filled with the flowable substance, the flowable substance can flow through the opening without interrupting airflow through the opening when the container is tilted over a range of tilt angles of at least 25 degrees, and in one embodiment, over a range of approximately 35 degrees.
According to other aspects of the invention, the container body has a concave area positioned adjacent to the opening and flat panels on opposed sides thereof. According to a further aspect, the container includes a handle adapted to be grasped by a user, and the handle is oriented in alignment with the major axis of the elliptical opening.
Additional aspects of the present invention relate to a container for containing a flowable substance that includes a container body, a non-circular opening in the container body, and a resealable closure affixed over the opening. The container body defines an internal cavity that is adapted to contain the flowable substance therein. The opening is adapted to allow the flowable substance to flow therethrough. The resealable closure is adjustable between an open position, where the flowable substance can flow through the opening, and a closed position, where the closure obstructs the opening to prevent the flowable substance from flowing through the opening. When the closure is in the open position and the container is substantially filled with the flowable substance, the flowable substance can flow through the opening without interrupting airflow through the opening when the container is tilted over a range of tilt angles of at least 25 degrees, and in one embodiment, over a range of approximately 35 degrees.
Further aspects of the present invention relate to a container for containing a flowable substance that includes a container body, an elongated opening in the container body, and a resealable closure affixed over the opening. The container body defines an internal cavity that is adapted to contain the flowable substance therein. The opening is adapted to allow the flowable substance to flow therethrough. The resealable closure is adjustable between an open position, where the flowable substance can flow through the opening, and a closed position, where the closure obstructs the opening to prevent the flowable substance from flowing through the opening. When the closure is in the open position and the container is substantially filled with the flowable substance, the flowable substance can flow through the opening without interrupting airflow through the opening when the container is tilted over a range of tilt angles of at least 25 degrees, and in one embodiment, over a range of approximately 35 degrees.
Other features and advantages of the invention will be apparent from the following specification taken in conjunction with the following drawings.
To understand the present invention, it will now be described by way of example, with reference to the accompanying drawings in which:
While this invention is susceptible of embodiments in many different forms, exemplary embodiments of the invention are shown in the drawings and will herein be described in detail with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
Referring initially to
The container 10 may be manufactured from any suitable material known in the art of container production. In one exemplary embodiment, the container is made of high-density polyethylene in a blow-molding process. In other embodiments, the container may be made of a different polymer material, such as low-density polyethylene, polyethylene terephthalate, polypropylene, polyvinyl chloride, or polystyrene, or of a non-polymeric material, such as glass. Additionally, the container may be made using different techniques, which may be influenced by material choice.
In the embodiment shown in
The container 10 shown in
As best illustrated in
In many applications, the container 10 includes a closure to cover the opening 16, preventing unwanted spilling of the contents, contamination, etc. In some embodiments, the container 10 may include a resealable closure to allow the container 10 to be selectively opened or closed. Examples of such closures include a snap-on closure, a flip-top closure, a plug closure, or many other types of resealable closures known in the art. In certain embodiments, the opening 16 may include a neck allowing for attachment of such a closure. Generally, such a resealable closure is adjustable between an open position, where the flowable substance can flow through the opening 16, and a closed position, where the closure obstructs the opening 16 to prevent the flowable substance from flowing therethrough.
The closure 40 illustrated in
The features of the exemplary embodiments of the containers 10, 110 herein provide for improved rate and control of pouring of the flowable substance from the container 10, 110. The narrowed front 70 of the opening 16 provides for a slow initial pour, increasing control of pouring and decreasing spilling and splashing, particularly when the container 10 is tipped along the axis A during pouring. The elongated nature and orientation of the opening 16 permits increased airflow back through the rear 72 of the opening 16 during pouring without obstructing or interrupting such airflow, increasing maximum flow rate and reducing glugging during pouring. Reduced glugging also results in increased pouring control and reduced spilling and splashing.
As illustrated by
Several alternative embodiments and examples have been described and illustrated herein. A person of ordinary skill in the art would appreciate the features of the individual embodiments, and the possible combinations and variations of the components. A person of ordinary skill in the art would further appreciate that any of the embodiments could be provided in any combination with the other embodiments disclosed herein. It is understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein. The terms “top,” “bottom,” “length,” “width,” etc., as used herein, are intended for illustrative purposes only and do not limit the embodiments in any way. Additionally, the term “plurality,” as used herein, indicates any number greater than one, either disjunctively or conjunctively, as necessary, up to an infinite number. Accordingly, while the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention and the scope of protection is only limited by the scope of the accompanying claims.
