Abstract
A combination receptacle opener including a plate member having at least one aperture with serrations for gripping for twisting off a twist-cap inserted into the aperture. The aperture also includes a segment for engagement beneath the lip of a crown cap for prying the cap off its bottle, this second function being performed from the same face of the plate member as the twisting function. Further embodiments include tang members extending from one face of the plate member around an aperture, which serve as insertion depth regulations for twist-cap inserted into the aperture, and a baffle extending from one face of the opener around an aperture for adjusting the operative diameter of the aperture for use with smaller twist-caps.
Claims18
A combination receptacle opener, comprising:
- a plate member having two faces and an aperture, wherein a portion of the inner surface of the plate member surrounding the aperture includes serrations for gripping for twisting off a twist-cap inserted flatly into the aperture (i.e., in such a way that the plane of the top of the cap is parallel to the plane of the plate member), and a further portion of such inner surface includes means for engaging a crown cap such that the serrated portion of such inner surface serves as a fulcrum for prying such a cap off its bottle, wherein in each case, the twist-cap or the crown cap is first inserted into the same face of the plate member (hereinafter the "insertion face") for removal.
A combination receptacle opener, comprising:
- a plate member having two faces and an aperture, wherein a portion of the inner surface of the plate member surrounding the aperture includes serrations for gripping for twisting off a twist-cap inserted flatly into the aperture (i.e., in such a way that the plane of the top of the cap is parallel to the plane of the plate member), and a further portion of such inner surface includes means for engagement beneath the lip of a crown cap for prying such a cap off its bottle, wherein in each case, the twist-cap or the crown cap is first inserted into the same face of the plate member (hereinafter the "insertion face") for removal;
- and
- a baffle member extending from the non-insertion face of the plate member at a site along the surface surrounding the aperture, such baffle so positioned that when a twist-cap of a certain size (i.e., having a diameter too small to allow frictional contact with the serrations when inserted so that the plane of the top of the cap is parallel to the plane of the plate member) is inserted into the aperture in such a way fhat the plane of the top of the cap is at an angle relative to the plane of the plate member, the baffle will be met by the cap at an oblique angle and thus cause a portion of the side of the cap to be toothedly engaged by the serrations for effective gripping for twisting off the twist-cap.
A combination receptacle opener, comprising:
- a plate member having two faces and an aperture, wherein a portion of the inner surface of the plate member surrounding the aperture includes serrations for gripping for twisting off a twist-cap inserted flatly into the aperture (i.e., in such a way that the plane of the top of the cap is parallel to the plane of the plate member), and a further portion of such inner surface includes means for engagement beneath the lip of a crown cap for prying such a cap off its bottle, wherein in each case, the twist-cap or the crown cap is first inserted into the same face of the plate memeber (hereinafter the "insertion face") for removal;
- and
- at least one tang member extending from the non-insertion face of the plate member at a site along the surface surrounding the aperture, such tang member being positioned so as to (i) define a limit for the insertion depth of a twist-cap inserted into the aperture, such limit allowing the serrations to continue to grip the twist-cap when the cap is inserted to the limit, and (ii) act as a baffle, such that when a twist-cap of a certain size (i.e., having a diamter too small to allow frictional contact with the serrations when inserted so that the plane of the top of the cap is parallel to the plane of the plate member) is inserted into the aperture in such a way that the plane of the top of the cap is at an angle relative to the plane of the plate member, the baffle will be met by the cap at an oblique angle and thus cause a portion of the side of the cap to be toothedly engaged by the serrations for effective gripping for twisting off of the twist-cap.
A combination receptacle opener, comprising:
- a plate member having two faces and an aperture, wherein at least a portion of the inner surface of the plate member surrounding the aperture includes serrations for gripping for twisting off a twist-cap that is inserted flatly (i.e., such that the plane of the top of the cap is parallel to the plane of the plate member) into the aperture from the insertion face of the plate member;
- and
- a baffle member extending from the non-insertion face of the plate member at a site along the surface surrounding the aperture, such baffle member so positioned that when a twist-cap of a certain size (i.e., having a diameter too small to allow frictional contact with the serrations when inserted so that the plane of the top of the cap is parallel to the plane of the plate member) is inserted into the aperture in such a way that the plane of the top of the cap is at an angle relative to the plane of the plate member, the baffle will be met by the cap at an oblique angle and thus cause a portion of the side of the cap to be toothedly engaged by the serrations for effective gripping for twisting off of the twist-cap.
A combination receptacle opener, comprising:
- a plate member having two faces, comprising:
- (a) first and second aperture arrangements, each including:
- an aperture, wherein at least a portion of the inner surface of the plate member surrounding the aperture includes serrations for gripping for twisting off a twist-cap that is inserted into the aperture from the insertion face of the plate member;
- at least one baffle member extending from the non-insertion face of the plate member at a site along the surface surrounding the aperture, such that when a twist-cap of a certain size (i.e., having a diameter too small to allow frictional contact with the serrations when inserted so that the plane of the top of the cap is parallel to the plane of the plate member) is inserted into the aperture in such a way that the plane of the top of the cap is at an angle relative to the plane of the plate member, the baffle will be met by the cap at an oblique angle and thus cause a portion of the side of the cap to be toothedly engaged with the serrations for effective gripping for twisting off of the cap;
- and
- a relatively straight segment along one portion of the inner surface surrounding the aperture;
- wherein the second aperture is generally smaller than the first aperture for accommodating a range of twist-caps of a generally smaller size;
- and
- wherein the relatively straight segments of the first and second apertures are proximate to one another on the plate member.
