Description
Background of the Invention
1. Field of the Invention
The present invention generally relates to bottle holding devices and, more particularly, is concerned with a handled closure device for use with standard size plastic bottles, such as one and two-liter plastic beverage containers or bottles.
2. Description of the Prior Art
The utilization of one- and two-liter plastic bottles as standard beverage containers has gained mass market acceptance in recent years. The resilience and durability of such bottles provides important benefits to the average consumer. A certain difficulty may be experience, however, by some consumers in pouring a beverage satisfactorily from such bottles. For example, people with reduced muscular strength in hands and arms, such as children or adults with arthritis or similar conditions, may experience difficulty in handling these types of bottles and in pouring beverages therefrom without spillage.
A variety of bottle holding devices have been developed providing features for overcoming such difficulties. Representative examples of such devices are disclosed in U.S. patents to Beekes (U.S. Pat. No. 4,456,135), Watson et al (U.S. Pat. No. 4,666,197), Polotti (U.S. Pat. No. 4,667,354), Reyes Jr. (U.S. Pat. No. 4,842,158), Kennedy (U.S. Pat. No. 4,896,913), Russell (U.S. Pat. No. 4,936,614), Robbins III (U.S. Pat. No. 4,982,869) and Gilmour (U.S. Pat. No. 5,078,291).
Most of the above cited devices are designed particularly for use with one- and two-liter plastic bottles. The Robbins III device may be utilized with a wider range of container sizes holding various solid substances as well as a variety of liquids. The Gilmour device is principally for use with a much larger plastic bottle typically supplying bottled water for water dispensers.
The Gilmour device provides a cap feature having handle components attached directly thereto, being attachable together above the cap. The Beekes and Russell devices each basically provide a top annular feature attachable to the neck of a bottle and a specific type of handle attached to the top feature and extending downwardly therefrom for pouring liquid from the bottle.
Each of the other aforecited devices provides a top annular feature attachable to the neck of a bottle and one or more lower annular band structures for holding the body of a bottle. Also, each of the these other devices has a particular type of handle being attached between the top annular features and lower annular band or bands providing a pouring capability for the device.
Several of these devices seem complex in design and construction and therefore costly in production. Such devices include the Beekes, Polotti, Reyes Jr., and Robbins III devices. Additionally, such complexity in design of these devices tends to make use thereof rather cumbersome and inefficient for many people. Further, the Watson, Kennedy and Russell devices seem somewhat awkward to use due to the extended length of the particular handles thereof.
Consequently, a need still exists for a bottle handling device which substantially eliminates the drawbacks of the prior art without introducing other drawbacks in their place.
Summary of the Invention
The present invention provides a handled closure device designed to satisfy the aforementioned needs. The handled closure device of the present invention provides expanded capabilities not available in the prior art bottle handling devices.
One capability is the simplicity in design and construction of the handled closure device for inexpensive production thereof and for ease in use by both children and adults, including those with limited muscular strength. A second capability is the easy installation and removal of the attachment feature of the device with respect to a bottle, thereby promoting the long life of the device. A third capability is the manner in which the device is securely tightened to the threaded portion of the bottle so as to give the device and bottle the feel of a one-piece assembly with the weight of the bottle being adequately leveraged by the handle of the device for pouring liquid therefrom without spillage.
Accordingly, the present invention is directed to a handled closure device which includes a closure body, a closure cap and a handle. The closure body has spaced upper and lower portions and defines an interior cavity extending between the upper and lower portions. The interior cavity of the closure body has an open bottom adapting the closure body to be fitted over and receive an upper portion of a bottle containing a liquid. The closure cap fits on the upper portion of the closure body. The handle disposed on the exterior of the closure body is attached to and extends between the upper and lower portions of the closure body.
The handled closure device also includes means in the form of first interfitting elements defined on the closure cap and the upper portion of the closure body. The first interfitting elements are adapted to mount the closure cap on the upper portion of the closure body for undergoing rotational movement by the user turning the closure cap relative to the closure body between an opened position wherein flow of liquid is permitted from the bottle through the closure device and a closed position wherein flow of liquid is prevented from the bottle through the closure device.
In a first embodiment of the closure device, the first interfitting elements includes a series of internal screw threads defined on an interior surface of a cylindrical sidewall portion of the closure cap and a series of external screw threads defined on an exterior surface of a cylindrical wall portion of an upper annular head of the closure body. The series of external screw threads are threadably engaged with the series of internal screw threads to permit rotation of the closure cap by the user between the opened and closed positions relative to an open top on the closure body.
In a second embodiment of the closure device, the first interfitting elements includes an annular groove defined in an exterior surface of an annular sidewall portion of the upper annular head of the closure body and an annular rib defined on an interior surface of an annular sidewall portion of the closure cap. The annular rib is received in the annular groove to permit rotation of the closure cap by the user between the opened and closed positions relative to the upper annular head of the closure body.
Also, in the second embodiment of the closure device, the closure cap and upper annular head of the closure body have respective apertures formed therein. The apertures are aligned with one another when the closure cap is disposed at the opened position relative to the upper annular head of the closure body and are displaced from one another when the closure cap is disposed at the closed position relative to the upper annular head of the closure body. Further, the closure cap and the upper annular head of the closure body have respective venting passages formed therein. The venting passages are aligned with one another when the closure cap is disposed at the opened position and are displaced from one another when the closure cap is disposed at the closed position relative to the upper annular head of the closure body.
The handled closure device further includes means in the form of second interfitting elements defined on the closure body. In both first and second embodiments of the closure device, the second interfitting elements is a series of internal screw threads defined on an interior surface of the closure body. The series of internal screw threads are adapted to be removably and rotatably threaded by the user with the series of external screw threads on the upper portion of the bottle to securely mount the closure device on the bottle.
These and other features and advantages of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings wherein there is shown and described an illustrative embodiment of the invention.
