Tool and method for opening a vacuum sealed bottle

Abstract

A tool and method for puncturing a lid of a vacuum sealed bottle to release the vacuum and allow easy opening. A point extends down from the tool, and force may be exerted against the tool by the palm or thumb of a user causing the point to penetrate the lid. The point preferably extends between 3/16 inches and 1/16 inches down from the handle, and more preferably about 3/16 inches. In some embodiments the tool is mushroom shaped having a wider round or oval upper portion for grasping and a narrower lower portion centered under the upper portion of the handle, the point extending down from the lower portion.

DETAILED DESCRIPTION OF THE INVENTION

(20) The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.

(21) Referring to FIG. 1, one embodiment of a lid puncturing tool 10a of the present invention is shown, the tool 10a comprises a handle 20 and a point 14. The tool 10a has an overall height (not including the point 14) H of about 1.1 inches, the handle 20 has a height H1 of about 0.6 inches, and the handle 20 is a height H2 of about 0.5 inches above the point 14. The handle 20 is configured to be held in the hand of a user and has a smooth circular convex top surface 16 against which pressure may be exerted by the palm, fingers, or thumb of the user, and a smooth rounded bottom surface 12 to facilitate grasping. An integral bottom portion (or spacer) 22 preferably resides below the handle 20. The spacer 22 preferably has a substantially cylindrical shape, and is sized to accommodate a user's index and middle fingers when the user holds the handle 20. A flat disk-like section 23 may reside under the spacer 22 and extends the diameter of the spacer 22 by a small amount.

(22) The point 14 extends down a depth d below the bottom surface 18 of the section 23 and the point 14 is configured to penetrate a vacuum sealed lid when force is exerted against the top surface 16 of the handle 20. The point 14 preferably extends the depth d between 1/16 and inches below the bottom surface 18, and more preferably the point extends about 3/16 inch below the bottom surface 18.

(23) Referring to FIG. 2, another embodiment comprising a tool 10b is shown, which is similar to the embodiment of FIG. 1 but does not include the section 23. Accordingly, for ease and consistency of description, when appropriate, the same element numbers will be used in FIG. 2 as used in FIG. 1. The tool 10b also comprises a handle 20 and a point 14. The point 14 extends from the bottom surface 28 of a spacer 30 replacing the spacer 22. The point 14 of the tool 10b is the same length as the point 14 described above.

(24) FIGS. 3 and 4 show top plan views of the tools 10a and 10b respectively. The handle 20 has a diameter D. The diameter D is preferably between 1.5 and 2.5 inches, and more preferably between 1.5 and two inches, and most preferably about 1.5 inches. The handle 20 may also be oval of about the same size.

(25) FIG. 5 shows a bottom view of the tool 10a. The section 23 has a diameter D1 of about 0.6 inches and is preferably a little greater than the diameter of the handle 20. The point 14 has a diameter D2 of about 0.15 inches.

(26) FIG. 6 shows a bottom view of the tool 10b. The spacer 30 has a diameter D3 of about 0.5 inches and is preferably about the diameter of the handle 20.

(27) Referring to FIGS. 7 and 8, tools 10c and 10d are shown wherein the respective tools 10a and 10b are each fitted with a layer 32 of compressible material. The compressible material can be in the form of a rubber or rubber-like washer, or a disk of felt, or a disk of a loop material of a hook and loop material, or similar compressible material. The point 14 extends through the layer 32 about 1/16 inch beyond the layer 32 when the layer 32 is uncompressed, reducing the likelihood of scratching or puncturing the skin of a user, or of kitchen items. The point 14 attached to the handle 20 at 14a, and has a tip 14b opposite to the handle 20.

(28) Cross-sectional views of the tools 10a, 10b, 10c, and 10d taken along lines 9, 10, 11, and 12 of FIGS. 1, 2, 7, and 8 are shown in FIGS. 9, 10, 11, and 12 respectively. The point 14 is defined by an exposed conical portion 15a and an attached cylindrical portion 15b (see FIG. 13A). The handle 20 is formed with a hole 40 for receiving the cylindrical portion 15b, which is secured therein. The hole 40 and shank 36 may include respective mating female and male screw threads so that the shank can be screwed into the handle (and easily replaced if needed).

(29) Details of a point 14a are shown in FIG. 13A. The point 14a has an overall length L of about 0.5 inch from its base 38 to a tip 39, a length L1 of about inches of a conical portion 15a, and a length L2 of about inches of the cylindrical portion. The conical portion 15a forms an angle A of preferably between 20 and 40 degrees and more preferably about 30 degrees from a centerline CL of the point 14. The cylindrical portion 15b includes male threads for cooperating with female threads in the hole 40. Using a threaded point 14a provides an advantage of being able to adjust the extent of protrusion of the point 14a from the handle 20.

(30) A second point 14b shown in FIG. 13B provides an interference fit with the hole 40. A smaller diameter stepped end 17 allows the point 14 to be easily started in the hole 40, and then mechanically pressed into a final position.

(31) The point 14 may also be secured by use of an adhesive, such as Locktite B (Eastman 9-10), secured by plastic injection molding, or the like. The handle 20 may be formed by plastic injection molding and the point 14 may include a medium knurl for retention.

(32) The handle and shank can be formed of the same or different materials. For example, the handle can be formed of ceramic material, or other material, or both the shank and handle can be formed of stainless steel or other metal. Preferably the handle is formed of a ceramic material, or of hardwood or plastic, and the shank is formed of stainless or other steel, preferably heat-treated. In an alternative embodiment, the handle and point are formed in one piece from plastic or steel, or other metal.

(33) The tool 10 is shown above a vacuum sealed bottle 52 and lid 50 in FIG. 14A, and after puncturing the lid in FIG. 14B. The length and pitch of the point 14 were selected after significant experimentation to puncture the lid 50 with little effort and to minimally puncture the lid 50 which is sufficient to release pressure vacuum in the bottle 52 allowing easy removal of the lid 50 from the bottle 52. Providing a minimal puncture allows the lid 50 to be reattached and provide a useful sealing of the bottle 52 after initial opening.

(34) A method for puncturing a lid of a vacuum sealed bottle to allow easy removal of the lid is shown in FIG. 15. The method includes the steps of grasping a handle of a lid puncturing tool at step 100, holding the tool to position a point extending down from the tool against a lid of a vacuum sealed bottle at step 102, pressing the point against the lid with sufficient force to puncture the lid at step 104, releasing vacuum from the bottle at step 106, removing the lid from the bottle at step 108, removing contents from the bottle at step 110, replacing the lid onto the bottle at step 112, and placing tape over the puncture in the lid at step 114. When the entire contents of the bottle are removed, there is no need to perform steps 112 and 114.

(35) The tool 10 may further find application in scoring fruit skins to facilitate peeling, tearing tamper proof seals to facilitate removal, tearing packaging tape to open packages, perforating frozen food covering before microwave cooking, perforating a canned drink lid to allow the lid to relax to expose a pull tab.

(36) While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
