DETAILED DESCRIPTION

(17) While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward. It is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms.

(18) The present invention provides a novel and efficient a pressure-reducing bottle cover that is operably configured to safely and effectively discharge accumulated gas within a container before the cover or cap is removed by the user. Referring now to FIGS. 1-2, one embodiment of the present invention is shown in cross-sectional views. The figures herein show several advantageous features of the present invention, but, as will be described below, the invention can be provided in several shapes, sizes, combinations of features and components, and varying numbers and functions of the components. The first example of a pressure-reducing bottle cover 100, as shown in FIG. 1, includes a cap body 102 removably coupled to the distal end 104 of the container 106 in a hermetically sealed configuration, i.e., preventing gases (represented with arrows 108 in FIGS. 1-2) housed within the container 106 from unintentionally escaping. In one embodiment, the container 106 may be bottle, e.g., a sparkling wine bottle, and the cap or cover body 102 may be sparkling wine cover of a cork material.

(19) With brief reference now in conjunction with FIGS. 3 and 5, the cap body 102 may include a first end 300, a second end 302 opposite the first end 300 of the cap body 102, and a cap length 304 spanning from the first end 300 to the second end 302. Beneficially, a button 110 or nodule cover 500 can be seen disposed at the first end 300 of the cap body 102. In one embodiment, the button 110 is disposed at the terminal end of the body 102 (as shown in FIGS. 1-2) where a user can effectively and efficiently apply pressure to depress the button 110. In one embodiment, the body 102 and button 110 are of a polymeric material that are deformably resilient, e.g., natural rubber having a shore A hardness of approximately 20-50. The button 110 may be formed through an overmold manufacturing process that may define a recess 206 spanning a perimeter of the button 110, thereby enabling a more efficacious translation/deformation of the button 110. The button 110 also includes a lower surface 200, opposing an upper surface 202 where a user applies a force (represented with arrow 204) to translate/deform the button 110. In other embodiments, the nodule cover 500 is also disposed at the terminal end of the body 102 (as shown in FIG. 5), may be relatively planar or plate-like, shaped like a disc, and is of a substantially rigid (also referred to herein as rigid) polymeric material, e.g., PVC having a shore A hardness greater than approximately 80. The nodule cover 500 beneficially prevents inadvertent depression of the stem displacement nodule 336 when, for example, the bottle or other container is in transport. Said another way, the nodule cover 500 may be inflexible under forces greater than or equal to approximately 1-2 lbf. The button 110 and cover 500 also includes a lower surface 200, opposing an upper surface 202. When used as a button 110, the user applies a force (represented with arrow 204) to translate/deform the button 110.

(20) Still briefly referring to FIG. 3 in conjunction with FIGS. 1-2, the cap body 102 defines and surrounds a cap channel 306 defined and surrounded by the cap body 102. The cap channel 306 has a first channel end 308 and a second channel end 310 opposing the first channel end 308. Separating the first and second channel ends 308, 310 may be a channel length, wherein the channel length may substantially span, i.e., greater than 75% of or approximately equal to, body length 304. The channel 306 has a valve assembly 312 disposed within the cap channel 306, wherein the valve assembly 312 includes a valve stem 314 with a distal valve end 316. The valve assembly 312 includes a spring 318 operably configured to bias the valve stem 314 in a direction toward the lower surface 200 of the button 110. In one embodiment, the spring 318 is a compression spring of a stainless-steel material with a spring constant of approximately 55-75 lbf/in. The spring 318 may be seated within the channel 306 to bias the distal end 316 of the valve stem 314 proximal to, i.e., at or near, the lower surface 200 of the button 110.

(21) In one embodiment, the valve stem 314 of the valve assembly 312 may include a valve shoulder 328 disposed at an end of the valve stem 314 generally opposing the distal end 316, but positioned proximal to the second channel end 310. More specifically, the valve shoulder 328 includes an outer surface 330 operably configured to be seated in a hermetically sealed configuration with the second end 302 of the cap body 102 when the valve stem 314 is in a static position (shown best in FIG. 3) along the stem translation path 208, i.e., with the biasing force of the spring 318, via the geometric constraints of an internal shoulder 332 of the body 102 and a lower end 334 of the stem displacement nodule 336. In one embodiment, the valve shoulder 328 includes a first diameter, e.g., diameter 338 of approximately 0.5 inches, greater in length than a diameter, e.g., diameter 340 of approximately 0.2 inches, of the second channel end 310 and a second diameter, e.g., diameter 342 of approximately 0.15 inches, less in length than the diameter of the second channel end 310. In one embodiment, a shoulder length separates the first and second diameters 338, 342, wherein the valve shoulder 328 is of a uniform tapered width spanning the shoulder length. Said differently, the valve shoulder 328 may also be of a conical shape, or of another shape with a geometric configuration operable to create a hermetic seal with the second end 302 and second channel end 310. In one embodiment, the second end 302 of the cap body 102 is also beneficially of a conical shape conforming to the conical shape of the valve shoulder 328 to effectuate a tighter seal when the stem 314 is in the static position. In one embodiment of the present invention the outer surface 330 of the shoulder 328 may be of a deformably resilient material, e.g., natural rubber, to effectuate a tight and/or hermetic seal. In other embodiments, the outer surface 330 of the shoulder 328 may be of a substantially rigid material, e.g., stainless steel, PVC, etc., and include a rubber gasket disposed thereon.

(22) In another embodiment of the present invention, a valve assembly 400 as depicted in FIG. 4 may be employed. In this embodiment, the valve assembly 400 is disposed within a cap channel 402 and lockably retained in a position through use of a corresponding threaded configuration between the body 102 of the cap and the valve assembly 400. In one embodiment, a portion 404 along a length of the valve assembly 400 may include a gasket 406 to hermetically seal and seat the valve assembly 400 within the cap channel 402. In other embodiments, the threaded configuration may provide the hermetic seal.

(23) The body 102 also includes one or more gas discharge ports, e.g., ports 320, 322, defined on an outer surface 324 of the cap body 102. The gas discharge port(s) 320 is in fluid communication with the first channel end 308 to provide an exit for the accumulated gas 108 within an internal cavity 112 of the container 106 when the stem 314 is a gas-evacuation position (shown best depicted in FIG. 2) along a stem translation path (represented with arrow 208 in FIG. 2). In one embodiment, the gas translation path 208 is linear. In another embodiment, the gas translation path 208 is curvilinear. In one embodiment, the gas discharge port(s) 320 are of a plurality of ports disposed in the recess 206 spanning the perimeter of the button 110 so that the user can effectively feel the discharged gas downstream of the internal cavity 112 as it passed through the cap channel 306 and through the gas discharge port(s) 322. The gas discharge port(s) 322 may be of circular shape having a diameter of approximately 10-15 mils, but may be outside of said range and of another shape in other embodiments. Additionally, the gas discharge port(s) 322 may be disposed on a side surface 326 of the body 102, but at a location above the distal end 104 the container 106 when the cap body 102 is coupled to the container 106.

(24) With reference to FIGS. 5-7 and FIGS. 9-14, the nodule cover 500 may seat on the first end 300 of the cap body 102 through, for example, a recess and platform 1300 (shown best in FIG. 13) formed on the first end 300 of the body 102. Said another way, the recess 504 and platform 1300 on the first end 300 is shaped and sized to receive and support the nodule cover 500. In one embodiment, the platform 1300 may continuously span and support the nodule cover 500, while in other embodiments it may discontinuously span and support the nodule cover 500. In some embodiments, the nodule cover 500 may also include an adhesive disposed at the bottom of the nodule cover 500.

(25) As specifically seen in FIGS. 6-7, the wire-cover assembly or muselet 600, a wire cage assembly that also includes a muselet cap 602 defining a muselet cap aperture 900, are operably configured to cover and/or retain the cork, thereby preventing inadvertent emission or dislodging. The cap aperture 900 is best shown in FIG. 9 and is shaped and sized to permit entry and egress of the nodule cover 500, i.e., it has a geometry and/or dimensions greater than the geometry and/or dimensions of the nodule cover 500. In one embodiment, the nodule cover 500 is circular and has a diameter that is approximately 0.5 inches, wherein the cap aperture 900 is also circular and is approximately 0.6 inches. In other embodiments, the shape and sizing may vary. The cap aperture 900 may also conform or correspond to the shape of the nodule cover 500. While in transport and before use, the muselet 600 and nodule cover 500 may be surrounded and/or retained by a wrapper 604, which may be of a metallic foil or other deformable material. The nodule cover 500 may also be height when seated in and flush configuration in and with the top of the cap body 102 such that it does not exceed the height of the cap 602.

(26) Therefore, in one embodiment when in the container is desired to be used, the user may remove all or a portion of the foil wrapper 604, thereby exposing the nodule cover 500 for removal by the user. Said another way, the nodule cover 500 is selectively removably coupled to the top of the cap body 102 when the wrapper 604 is in a removed position along a wrapper removal path. In another embodiment, as best shown in FIG. 6, the wrapper 604 may be coupled to a portion of the rigid nodule 500 through use of a fastener 606, e.g., adhesive. As such, when the user desires to open the container and removes the wrapper 604, the rigid module cover 500 will also be removed simultaneously. The recess 504 defined by the first end 300 of the cap body 102 facilitates in supporting the nodule cover 500. Said another way, the recess 504 provides room for the nodule cover 500 to seat on top of the cap body 102. In one embodiment, the sidewalls of the cap body 102 defining the recess 504 prevent lateral movement of the nodule cover 500 when inserted therein. The muselet cap aperture 900 and recess 504 may be shaped and sized to permit entry and egress of the nodule cover 500 through the same when the wrapper 604 is removed. When seated in the cap body 102, the lower surface 200 of the nodule cover 500 may be disposed proximal to, i.e., at or preferably near (within 1 inch), the stem displacement nodule 336. The nodule cover 500 may include an indentation 502, approximately 0.25-0.75 inches in length, that may allow a user to effectively and quickly remove the nodule cover 500 with his or her fingernail and when not fastened to the wrapper 604. When the nodule cover 500 is removed, the muselet 600 and muselet cap 602 are still coupled to and/or retaining the cap body 102 to the container 106, but the stem displacement nodule 336 and the first channel end 308 of the cap channel 306 are exposed for releasing of the gases within the container, i.e., by placing the valve assembly 312 in a gas-evacuation position.

(27) As discussed above, and with reference to the process-flow diagram depicted in FIG. 8 in conjunction with FIGS. 1-7 and 9-14, an exemplary method of relieving gas within an internal cavity of a container is illustrated. Specifically, the figures will be described in conjunction with the process flow chart of FIG. 8, and although FIG. 8 shows a specific order of executing the process steps, the order of executing the steps may be changed relative to the order shown in certain embodiments. Also, two or more blocks shown in succession may be executed concurrently or with partial concurrence in some embodiments. Certain steps may also be omitted in FIG. 8 for the sake of brevity. In some embodiments, some or all of the process steps included in FIG. 8 can be combined into a single process.

(28) The process begins at step 800 and immediately proceeds to step 802, which includes directly coupling an outer surface of a cap body to an internal surface of a distal end of the container (as depicted in FIGS. 1-2) to hermetically seal the internal cavity of the container from the ambient environment. As discussed above, the cap body may include a button/switch disposed thereon, a gas discharge port disposed above the distal end of the container where the cap body is coupled, and will define and enclose a cap channel with a valve assembly disposed therein. Otherwise, the cap body will include a nodule cover 500 operably configured to seat on and be removed from the cap body 102 to expose the stem displacement nodule 336. The valve assembly 312 may hermetically seal a portion of the cap channel with the internal cavity of the container, i.e., fluidly separate the internal cavity from the cap channel. In one embodiment, depending on the material of the cap body 102, e.g., cork or natural rubber, the cap body 102 will be operably configured to directly and deformably couple with the outer surface of said cap body to the internal surface the distal end of the container.

(29) When the cap body 102 is coupled to the container 106, the valve assembly 312 may be in the static position along the stem translation path 208, wherein with the distal valve end 316 of a stem displacement nodule 336 is disposed proximal to, i.e., at or preferably near (within 1 inch), the lower surface 200 of the button 200 and/or nodule cover 500. In one embodiment the stem displacement nodule 336 will be formed as one piece with the stem 314, and may be of a substantially rigid (also referred to herein as rigid) material, e.g., stainless steel, ceramic, or PVC, to effectuate transfer of force caused by the depression of the button 110. In other embodiments, the stem displacement nodule 336 may be coupled to an end of the valve stem 314 with friction fitting, adhesive, or other fastening means. In other embodiments, the stem displacement nodule 336 is preferably rounded or spherical to reduce the likelihood of jeopardizing the structural integrity of the button 110 and/or nodule cover 500. In the static position, the valve assembly 312 is in a hermetically sealed configuration with the cap body 102 to fluidly uncouple the first channel end 308 and the container cavity 112.

(30) In embodiments of the invention utilizing the nodule cover 500 to prevent inadvertent depression of the stem displacement nodule 336, the user will remove a portion of the wrapper and the rigid nodule cover from the cap body to expose the first channel end of the cap channel and the distal end of the valve stem, e.g., the stem displacement nodule 336. As such, cover 500 may rest freely on the platform 1300 in a closed position (shown best in FIG. 14) and, when the user removes the wrapper, the user can place it in an open position (shown best in FIG. 15) in a cover translation path (represented in an exemplary path with lines 1302). Next, step 804 may include depressing and longitudinal translating the distal end of the longitudinally biased valve stem in a stem translation path to fluidly couple the first channel end, the container cavity, and the ambient environment, thereby discharging a gas housed within the container cavity. Thereafter, as part of step 806, a user may remove the muselet 600 and muselet cap 602, which may be collectively referred to as the muselet, along with the cap body to expose a distal opening of the container defined by the distal end of the container for use.

(31) When the user desires to use a version of the invention with the nodule cover replaced by the button, the user would remove the muselet and/or wrapper to expose the button. Then, the user would depres an upper surface of the button until a lower surface of the button reaches and longitudinal translates a distal end of a longitudinally biased valve stem in a stem translation path to fluidly couple the first channel, the container cavity, and the gas discharge port together, thereby discharging a gas housed within the container cavity. In one embodiment, the amount of force required to flex the button and/or move the nodule/valve stem nodule may be approximately 1-2 lbf to reduce the risk of inadvertent gas emission. Additionally, the depression of the upper surface of the button may be in a parallel, axial, and longitudinal direction opposite the biasing force direction (best represented by arrow 210 in FIG. 2) of the longitudinally biased valve stem. Said another way, the valve assembly may include a gas-evacuation position (best shown in FIG. 2) along the stem translation path with the button 110 in a depressed position and directly coupled to the distal valve end 316 to fluidly couple the first channel 308, the container cavity 112, and the gas discharge port 322. Another view of the valve assembly in the gas-evacuation position can be seen in FIG. 12.

(32) Again, step 806 may now include safely and effectively removing the cap body to expose a distal opening of the container defined by the distal end of the container for use by the user. Beneficially, the cap body 102 may be reusable with the container or other containers, thereby providing an effective and efficient solution to reducing safety risks associated with internal pressure build-up. The process may then terminate at step 808.

(33) With reference to FIGS. 15-16, fragmentary cross-sectional views of exemplary pressure-reducing bottle covers in accordance with embodiments of the present invention. Specifically, exemplary rigid nodule covers 1500, 1600 are depicted disposed within the muselet cap aperture and selectively removably coupled to the cap body 102. As depicted in FIGS. 15-16, the rigid nodule covers 1500, 1600 may be of a substantially flush height with the surrounding terminal end of the cap body 102 or raised above the surrounding terminal end of the cap body 102.

(34) A pressure-reducing bottle cover has been disclosed that includes a cap or cover body that is operably configured to safely and effectively discharge accumulated gas within a container that the cap is coupled to before the cover or cap is removed by the user.
