Claims
I claim:
1. A bottle cap comprising:
A. a cap body;
B. a strip section through the length of the body with a pair of
lines formed by a series of perforations on the top of the body,
one line running along each side of the strip section, and a
corresponding pair of continuous grooves on the inside of the body
approximately opposite each line; and
C. a tab end extending radially from the strip section.
2. The bottle cap as recited in claim 1 including a cork seal on
the inside face.
3. The bottle cap as recited in claim 1 wherein the tab end has a
formed loop to insert a finger.
Description
The invention relates to bottle caps.
Bottle caps heretofore used require the aid of a lever tool
otherwise known as "bottle openers" to remove the caps from
bottles. The present invention eliminates the need for any tools
and permits a bottle to be pointed away from a person when the
bottle cap is removed.
In a preferred embodiment I provide a bottle cap comprising a
metallic cap having a middle strip section with a tab end extending
radially from the strip section. The strip section has a line
formed by a series of perforations on each side of the strip on the
top of the cover with a pair of corresponding grooves opposite the
pair of perforated lines and along the entire length of the cover
on that surface which faces toward a bottle opening. A cork seal is
placed on the inside of the cap.
In the foregoing general description I have set out certain
objects, purposes and advantages of my invention. Other objects,
purposes and advantages of this invention will be apparent from a
consideration of the following description and the accompanying
drawings in which:
FIG. 1 is a perspective view of a bottle with a bottle cap;
FIG. 2 is a perspective view of a bottle cap and a sealing means
which depicts the manner to detach the bottle cap;
FIG. 3 is a perspective view of the bottle cap which depicts the
state of the bottle cap after use;
FIG. 4 is a top sectional view of the bottle cap; and
FIG. 5 is a section view of the bottle cap in FIG. 4 taken along
the line V--V.
A bottle cap 1 appears as a conventional metallic bottle cap with a
radially extending tab end 4 formed in a loop to insert a finger as
shown in FIG. 2. Tab end 4 is an appendage of middle strip section
2 which is divided by perforated lines 3 on the top of the cap and
an undercut groove 3' on the inside of the cap approximately
opposite the perforated lines. A cork 5 seals the inside of the
cover 1.
To detach the bottle cap 1, the tab end 4 is pulled across the
bottle cap as shown in FIG. 2. As middle section 2 is torn from
cover means 1, tension in the cap 1 is lost and pressure in the
bottle escapes by forcing cork sealing means 5 against the cap 1.
The cap 1 bridles the cork 5 and directs the releasing pressure
away from said person if the bottle is pointed with the tab end 4
away from the person.
