Definitions

  • the present disclosure is related to a device that assists with equalizing air pressure within a bottle with the atmospheric air pressure, as liquid is being poured from the bottle.
  • a bottle 100 is shown in a cross-sectional view, wherein the cross-sectional alignment is taken along line 1-1 of the top elevation view of the bottle 100 depicted in Fig. 2 .
  • the bottle 100 includes a bottle wall 104 having an exterior surface 108.
  • the bottle wall 104 includes a base 112 and extends from the base 112 to the top 116 of the bottle 100.
  • the top 116 of the bottle 100 further includes a bottle opening 120 that leads to the bottle interior 124.
  • the bottle interior 124 is defined by an interior surface 128 of the bottle wall 104.
  • the bottle 100 has a bottle length B L , wherein the bottle length B L is defined herein as the height of the bottle interior 124; that is, the distance between the interior surface 128 of the bottle wall 104 at the deepest portion of the base 112 of the bottle 100 and a top edge 132 of the bottle rim 136 at the top 116.
  • FIG. 3 an enlarged cross-sectional view of an upper portion 140 of the bottle 100 is shown.
  • a variety of sealing mechanisms may be used to seal a bottle.
  • a threaded cap may be used to seal the bottle.
  • Such a configuration is illustrated in Fig. 3 , wherein a threaded cap 148 is depicted directly above the bottle 100.
  • the upper portion 140 of the bottle 100 includes a bottleneck 152. Threads 156 along the exterior surface 108 of the bottleneck 152 are configured to engage threads within cap 148.
  • the bottleneck 152 includes a substantially constant bottleneck diameter D Bottleneck .
  • the bottleneck 152 itself extends from the bottle rim 136 to a location where the bottle 100 begins its taper outward. That is, where the diameter of the bottle 100 increases from the bottleneck diameter D Bottleneck .
  • the bottleneck 152 has a bottleneck length L Bottleneck that is defined as the distance between the bottle rim 136 and the bottleneck base 160, which is the location where the bottleneck diameter D Bottleneck no longer remains substantially constant.
  • Prior devices for attempting to provide for smooth fluid pouring have performance issues, require significant materials, and/or have other limitations, such as extending above the bottle top, thereby complicating or even preventing recapping/resealing of the bottle. Accordingly, there is a need for other devices to address the glugging problem associated with pouring liquids from a bottle.
  • One or more embodiments of the one or more present disclosures are directed to a device that assists with equalizing air pressure within a bottle with the atmospheric air pressure, as liquid is being poured from the bottle.
  • Various embodiments of the pressure equalizers described herein can accommodate various bottle shapes, bottle sizes, liquids, and pouring angles.
  • the pressure equalizers are suitable for beverages, chemicals, solutions, suspensions, mixtures, and other liquids.
  • the pressure equalizer comprises two main fluid flow paths: (a) a channel that allows liquid to pass out of the bottle; and (b) one or more air tubes or air ducts to allow air to enter the bottle.
  • embodiments of the present disclosure are not limited to equalizing air pressure within bottles, but rather may be utilized to equalize air pressure in any container or vessel. As a couple of non-limiting examples, embodiments of the present disclosure may be employed to equalize air pressure in cartons, jugs, or any other hollow or concave structure for storing, pouring, and/or dispensing liquids.
  • At least one embodiment described herein utilizes one or more relatively short air tubes, as compared to the bottle length.

  • the pressure equalizer comprises at least one air tube with an air tube rim located substantially flush with the top of the bottle, or at least within 5% of the bottle rim relative to the length of the bottleneck. Unlike an insert used for alcohol bottles at a bar where the insert appears to be meant to slow the flow of liquid, embodiments described herein increase the flow of liquid and better facilitate air/gas entry into the bottle.
  • the pressure equalizers described herein mitigate or prevent the glugging effect that occurs when liquid is attempting to exit a bottle at the same time that air is attempting to enter the bottle.
  • At least some embodiments of the pressure equalizers can be incorporated directly into a current bottle mold design, a new bottle mold, or as an inserted device.
  • the device regardless of how it is incorporated into a bottle, involves one or more air tubes that extend partially into the bottle and allow air to pass into the bottle as the liquid exits the bottle. This device not only minimizes or prevents the common glugging effect, but it can allow liquid from a bottle to be poured smoothly at any angle.

  • a top of the air inlet channel is situated within a rim proximity distance above or below the bottle opening rim, the rim proximity distance equal to or less than about 5% of the bottleneck length L Bottleneck .
  • the bottle insert further comprises at least one additional air tube wherein the at least one additional air tube has an air tube diameter D AirTube between about 2% to 50% of the opening diameter of the bottle.
  • the bottle insert further comprises at least one additional air tube, the at least one additional air tube fluidly contiguous with the air inlet channel.
  • the bottle insert further comprises a flow block within the air inlet channel and situated between the air tube and the at least one additional air tube.

  • the air tube comprises a flared portion.
  • the flared portion includes a flared portion base that does not extend distally beyond the bottleneck base.
  • One or more embodiments include a pressure equalizer that includes an air tube having a flared portion. Accordingly, an article for holding and pouring a liquid is provided, comprising:

  • a manufacturing method may: (1) employ blow molding techniques to blow mold a smaller container top (e.g., having an inner diameter of approximately 11.5 mm); (2) extrude the air inlet(s); and (3) attach the air inlets to the inner sidewalls of the bottleneck using one or more of (friction welding, ultrasonic welding, radio frequency welding, heat welding, gluing, or the like).
  • a pressure equalizer that leaves the support ledge and throat of the bottle the same size. To do this, the entire top of the pre-formed container goes away, right down to the support ledge.
  • the pressure equalizer is then produced that includes the spout, air tubes, an appropriately-sized cap and a break-band to indicate that the cap has not been removed.
  • the pressure equalizer may then be attached (e.g., welded and/or glued) to the top of the pre-formed container.
  • each air tube is separately snapped into features within the spout.
  • a complete pressure equalizer may be provided with snaps or other friction fitting elements to snap the pressure equalizer into place relative to the body of the container.
  • Another advantage contemplated herein is the ability to employ bottle stacking. Specifically, since the bottle cap size is reduced (e.g., due to the reduction in the diameter of the bottle top), the top of one bottle or container may be sized to fit into the bottom of another bottle.
  • any number of materials may be used to manufacture the pressure equalizers described herein.
  • metal, metal alloys, non-metal alloys, ceramics, plastics, glass, and other materials used for the construction of container may be used for the pressure equalizers without departing from the scope of the present disclosure.
  • the top rim of the one or more air tubes associated with the pressure equalizer do not extend above the bottle rim 136 of the bottle 100.
  • a cap associated with the bottle can be reused with the pressure equalizer in the bottle 100.
  • Air tubes described herein preferably include solid, non-perforated tubing walls. That is, there are no holes along the side walls of the air tubes between the upper inlet rims 408 and the lower end edges 412 of the air tubes. In at least one embodiment of all of the various pressure equalizers described herein, there are no holes along the side walls of the air tubes between the upper inlet rims 408 and the lower end edges 412 of the air tubes. In at least one embodiment of all of the various pressure equalizers described herein, and as someone of ordinary skill in the art would appreciate, if present, any holes within the sidewalls of the air tubes preferably do not materially impact the flow characteristics of the subject pressure equalizer.
  • the lower end edges of the air tubes do not extend below about 25% of the bottle length B L .
  • At least a portion of the upper inlet rim 408 of at least one air tube is situated within a rim proximity distance that is less than or equal to 5% of the bottleneck length L Bottleneck .
  • the air tubes preferably include a diameter or equivalent diameter (by measuring the cross-sectional area of the air tube and solving for an equivalent diameter) that resides within a range of about 2% to 50% of the bottleneck diameter D Bottleneck .
  • the air tube length L Air Tube of the air tubes is greater than or equal to the bottleneck length L Bottleneck and less than or equal to about 25% of the bottle length B L (that is, L Bottleneck ⁇ L Air Tube ⁇ 25%B L ).
  • One, some, or all of the various pressure equalizers or containers described herein may further benefit from having air tubes that are specifically configured with a low-profile design that maximize the equalization of pressure between the interior of the container and the exterior of the container.
  • air tubes that are specifically configured with a low-profile design that maximize the equalization of pressure between the interior of the container and the exterior of the container.
  • many different shapes of air tubes were described.
  • An oval, oblong, tear-shaped, egg-shaped, or eye-shaped air tube may provide particularly good performance.
  • This particular shape of air tube may maximize the air inlets cross-sectional area near the outer diameter of the container opening but also maximize the amount of area through which fluid is allowed to travel out of the container.
  • a pressure equalizer or insert may be configured with some air inlets of one shape and some air inlets of another shape. Accordingly, a single container or pressure equalizer may comprise multiple air inlets, each having a different cross-sectional shape than any other air inlet.
  • a 1 liter soda container may have between three and six air inlets.
  • a 2 liter soda container may have between three and six air inlets.
  • a 1 liter water bottle may have between three and six air inlets.
  • a 1 liter juice bottle may have between three and six air inlets.
  • the length of the air inlets can be kept to a length of no longer than 3 inches per air inlet. Specifically, it may be revealed that air inlets longer than 3 inches in length are no more useful in equalizing pressure in a container than their shorter counterparts. Accordingly, in an attempt to control material costs, it may be desirable to maintain air inlet lengths to less than 3 inches.
  • containers with handles or other containers that have a generally constant pour direction may not require as many air inlets as containers without such a constant pour direction.
  • the direction with which a container is going to be poured is either controlled or somehow predictable, it may be possible to reduce the number of air inlets to one or two air inlets rather than three to six air inlets distributed evenly around the container opening.
  • the two or more air inlets may be grouped at one strategic location of the container opening rather than being evenly or randomly distributed about the container opening if the container has a direction of pouring that is somewhat predictable.
  • embodiments of the present disclosure may benefit from one or more manufacturing methods that were previously unknown in the container and bottle manufacturing arts.
  • the concept of building a fluid container that has substantially rigid (e.g., non-collapsable) body walls with an opening smaller than 15mm is something that has not been possible in the prior art due to the fact that fluid would simply get stuck in such a container without the advantage of the disclosed equalization mechanisms.
  • the way in which such a container or inlet for a container may be manufactured is to create a container perform with an opening smaller than 15mm.
  • the container perform may otherwise size the container in accordance with traditional design dimensions, but the container opening may be kept smaller than 15mm, thereby decreasing the amount of materials required to manufacture the container, increasing the pouring accuracy of the container, and the like.
  • air inlet tubes may be integral to the perform or they may be separately manufactured (e.g., via extrusion), cut to the desired length, and then attached to the container while it is still on the perform.
  • blow molding techniques can be employed to weld pre-manufactured air inlets into the desired location.
  • the blow molding process requires an increased heat, which may be sufficient to at least partially plasticize the container and/or air inlet material. This increased heat may also be sufficient to enable the air inlet to be stuck, adhered, welded, etc. to the inner wall of the container or insert opening.
  • a welder may be used to weld individual air inlet tubes into their desired location about the container and/or insert.
  • the pre-manufactured air inlets may be welded to the container and/or insert using any one of laser welding, ultrasonic welding, radio frequency welding, gluing/chemical welding, friction welding, spin welding, and shake welding.
  • a series of parts that include the finish (threaded male portion of the bottle) along with half of the support ledge (e.g., 4520, 4720, 4924, 5104, 5312, or 5724), the cap, the safety/tamper seal, the leakage seal, and the air inlets, can be installed at the capper stage of the line instead of capping a pressure equalization device that is already incorporated into a container.
  • the separate construction of the finish, support ledge, cap, tamper seal, leakage seal, and air inlets can be optimized separate from the construction of the container itself and a final step (before or after filling the container with the desired liquid) would be to connect to the container to the separately constructed finish and cap via the support ledge.
  • This final connection may be achieved using any of the welding, gluing, or other attachment techniques described herein or otherwise known in the container manufacturing arts.
  • the one or more present disclosures include components, methods, processes, systems and/or apparatus substantially as depicted and described herein, including various embodiments, subcombinations, and subsets thereof. Those of skill in the art will understand how to make and use the present disclosure after understanding the present disclosure.
  • the present disclosure includes providing devices and processes in the absence of items not depicted and/or described herein or in various embodiments hereof, including in the absence of such items as may have been used in previous devices or processes (e.g., for improving performance, achieving ease and/or reducing cost of implementation).
