Description
FIELD OF THE INVENTION

This invention relates generally to package opening devices, particularly including devices capable of opening a wide variety of packages, including bottles, cans, jars and bags.


BACKGROUND OF THE INVENTION

Many bottles, cans, and bags are tightly sealed and can be difficult to open. A typical household includes a variety of different devices for opening, including can openers, bottle openers, scissors, and special gripping devices. While each such device can be useful for its particular purpose, it would be better if a single device could perform the function of many different devices, eliminating the need for several devices while providing improved opening functions at the same time.


SUMMARY OF THE INVENTION

A container opening tool includes first and second legs hingedly secured to one another. Each leg has proximal and distal portions each having an aperture wall including a gripping material. The aperture walls of the proximal portions of the first and second legs form a proximal aperture and the aperture walls of the distal portions of the first and second legs are positionable to form a distal aperture. The proximal and distal apertures may have differing sizes and shapes. In one embodiment, the aperture walls of the distal portions define an elongate aperture, such as an oval or ellipse, with the first and second legs contacting each other near the major axis of the elongate shape. A projection may secure to an arcuate outer surface formed on the first leg and extend substantially tangentially from the outer surface. The projection is engageable with pull tabs of containers in order to lift the pull tabs upon pivoting the container opening tool relative to the container.


Bottle opening flanges secure to the first and second legs and project into the proximal aperture. When the legs are pivoted together, the flanges are positioned adjacent one another and function as a single bottle opener. The bottle opening flanges secure to the legs at the edge of the aperture walls such that a lid can be positioned within the proximal aperture having the flanges resting on the lid to aid in positioning the opening tool on the lid. In a like manner, skirts secure to the edges of the aperture walls of the distal portions and provide a surface engaging the top of a lid being opened.


The first and second legs each include a junction positioned between the proximal and distal ends. The junctions join the proximal and distal portions and include a gripping surface. The gripping surfaces of the junctions are placed in contact with one another when the legs are pivoted together in order to grip items such as safety seals covering container openings.


A blade secures to the second leg near the distal end. The distal ends of the legs are pressed together around a bag and the bag moved relative to the blade in order to cut an opening in the bag. In one embodiment, the blade is positioned within a recess formed proximate the distal end of the second leg. A projection is formed on the distal end of the first leg and positionable proximate the blade to press a bag against the blade.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1, 2A, and 2B, a container opening tool 10 includes a first leg 12a and a second leg 12b pivotally secured to one another by means of a pivot 14. The legs 12a, 12b are formed of a rigid material such as plastic, aluminum, steel, or the like. The legs 12a, 12b may also have an outer cover made of natural or synthetic rubber that provides cushioning and gripability to the user. The pivot 14 may be embodied as a pin 16 positionable within apertures 18a, 18b formed in the legs 12a, 12b. The aperture 18a in the leg 12a may be formed in two arms 20 positioned on either side of the portion of the leg 12b having the aperture 18b formed therein. The legs 12a, 12b include proximal and distal portions 22a, 22b each having an aperture wall 24a, 24b. The apertures walls 24a, 24b of the legs 12a, 12b are positionable adjacent one another to form proximal and distal apertures 26a, 26b.


The aperture walls 24a, 24b may be formed of a grippable material such that the legs 12a, 12b can be positioned around a lid or other structure to facilitate twisting. The aperture walls 24a, 24b may be formed of a material different than the material covering other parts of the tool 10 such that the aperture walls 24a, 24b are better suited for gripping lids. In the illustrated embodiments, the apertures 26a, 26b are of different sizes to accommodate differently sized lids. The aperture 26b may be embodied as an arcuate, elongate shape, such as an oval or ellipse, in order that the same aperture can readily grip lids of different sizes. The aperture walls 24b are typically portions of the elongate shape formed by dividing the elongate shape along its major axis. In this manner, when the legs 12a, 12b are closed, the length of the minor axis of the elongate shape is small enough to allow the legs 12a, 12b to close around small lids. The legs 12a, 12b may be expanded such that lids closer in size to the length of the major axis may also be gripped.


The legs 12a, 12b may have one or more bottle opener flanges 28a, 28b secured thereto and projecting outwardly from the aperture walls 24a. The flanges 28a, 28b of the legs 12a, 12b are positioned adjacent one another when the legs 12a, 12b are pivoted together to such that the combined flanges 28a and the combined flanges 28b each function as a conventional bottle opener flange suitable for opening bottles having crimped metal lids and the like.


In the illustrated embodiment, the flanges 28a, 28b are secured to the legs 12a, 12b near the edge of the aperture walls 24a. In this manner, the flanges 28a, 28b serve as stops, contacting the top of lids positioned between the legs 12a, 12b for gripping with the aperture walls 24a. A similar function may be provided by skirts 30 secured to the legs 12b along the edges of the aperture walls 24b. The skirts 30 and flanges 28a, 28b facilitate positioning of the apertures 26a, 26b around lids by encouraging the apertures to align with the rim of the lid such that the area of the aperture walls 24a, 24b in contact with the lid is substantially at its greatest possible extent.


A projection 32 secures to one of the legs 12a, 12b and facilitates opening of pull tab containers, such as canned beverages. In the illustrated embodiment, the projection 32 is wedge shaped and secures at its wide end to the leg 12a such that it projects substantially tangentially from the outer surface 34 of the leg 12a. The outer surface 34 of the leg 12a and an outer surface 34 of the leg 12b may together form a single arc. In use, the projection 32 can be positioned under a pull tab of a can with the legs 12a, 12b resting on the can proximate the pivot 14. The legs 12a, 12b may then be pivoted on the outer surfaces 34 such the projection 32 lifts the pull tab.


Referring to FIG. 3, while still referring to FIGS. 1, 2A, and 2B, the proximal and distal portions 22a, 22b of the first and second legs 12a, 12b are joined together at a junction 36. The junction 36 may include a gripping surface 38 such that the gripping surfaces of the legs 12a, 12b are in contact when the legs 12a, 12b are pivoted against one another. The gripping surface 38 may include texturing such as a series of parallel grooves and is typically formed of a gripping material such as a natural or synthetic rubber. The gripping surfaces 38 may be used to grip such things as safety seals secured to bottle openings in order to facilitate removal.


Referring to FIGS. 4 and 5, in one embodiment a blade 40 secures to the leg 12b, such as near a distal end 42 of the leg 12a, in order to cut open bags. In use, a bag is positioned between the distal end 42 of the leg 12a and a distal end 42 of the leg 12b. The distal ends 42 are pushed together and the bag is moved relative to the distal ends 42 such that the blade 40 cuts an opening in the bag.


In some embodiments, the blade 40 is positioned within a recess 44 formed near the distal end 42 of the leg 12b. The cutting edge of the blade 40 in such embodiments may be flush with, or below, the surface of the leg 12b. In such embodiments, a projection 46 may secure to the distal end 42 of the leg 12a and serve to press the bag against the blade 40. Recessed positioning of the blade 40 reduces the likelihood of injury through accidental contact and also hinders dulling of the blade 40 through contact with other cooking utensils in a storage drawer or dishwasher.


While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
