Definitions

• the field of the present invention generally relates to plastic containers. More particularly, the field of the invention relates to an apparatus and method for reducing foaming occurring with carbonated soft drink containers.
• PET containers have been used as a replacement for glass or metal containers in the packaging of beverages for several decades.
• the most common plastic used in making beverage containers today is polyethylene terephthalate (PET).
• Containers made of PET are transparent, thin-walled, and have the ability to maintain their shape by withstanding the force exerted on the walls of the container by their contents.
• PET resins are also reasonably priced and easy to process.
• PET bottles are generally made by a process that includes blow-molding of plastic pre-forms which have been made by injection molding of the PET resin.
• a drawback to plastic containers is that those that contain carbonated contents may allow foaming of the contents onto a consumer upon initially opening the container. In some cases, the foaming may be great enough to spill the contents of the container onto the lap of a consumer, or onto nearby furniture.
• Another drawback to plastic containers is that carbon-dioxide content within the containers must be limited so as to accommodate the foaming tendency of carbonated liquids. Limiting the carbon-dioxide content effectively decreases the shelf-life of the contents. What is needed, therefore, is an apparatus and method for decreasing the foaming tendency of bottled carbonated contents, such that the carbon-dioxide content may be increased, thereby increasing the shelf-life of the bottled carbonated contents.

• FIG. 1 illustrates a lower perspective view of an exemplary embodiment of a container 100 in accordance with the present disclosure.
• the container 100 comprises a base 104 that extends up to a grip portion 108.
• the grip portion 108 comprises a plurality of grip portion ribs 112 (i.e., sidewall ribs). As illustrated in Fig. 1, the plurality of grip portion ribs 112 generally may vary in depth, and may swirl or angulate around the grip portion 108.
• a label portion 116 is connected to the grip portion 108 and comprises one or more label panel ribs 120 (i.e., sidewall ribs). The label panel portion 116 transitions into a shoulder 124, which connects to a bell 128.
• a shoulder 124 which connects to a bell 128.
• the bell 128 comprises a plurality of scallops 132. In other embodiments, however, the bell 128 may include design features, or may be smooth and generally unomamented.
• the bell 128 connects to a neck 136, which connects to a finish 140. As shown in Fig. 1, the bell 128 comprises a diameter that generally decreases as the bell 128 extends upward from the shoulder 124 to the neck 136 and the finish 140.
• the finish 140 can be adapted to receive a closure to seal contents in the container 100, such as by way of non-limiting example, a container cap or bottle cap.
• the finish 140 generally defines an opening 144 that leads to an interior of the container 100 for containing a beverage, or other contents.
• Figure 2 illustrates an upper perspective view of an exemplary embodiment of the finish 140 that is configured to substantially reduce foaming of contents, particularly carbonated contents, during opening of the container 100.
• the finish 140 comprises a cylindrical body 148 that includes a peripheral portion with a first edge 152 and a second edge 156 disposed at opposite ends.
• the first edge 152 defines a first opening 160 and is configured to receive a container cap 164, or bottle cap, as shown in Fig. 3.
• the second edge 156 defines a second opening 168 and is configured to receive the neck 136 of the container 100, as shown in Fig. 1. It will be appreciated that the first and second openings 152, 156 are in fluid communication so as to define the opening 144 into the interior of the container 100 once the finish 140 is installed thereon.
• an exterior of the cylindrical body 148 comprises one or more threads 172 that are configured to rotatably engage with one or more threads 176 of the container cap 164.
• An engagement of the threads 172 of the finish 140 with the threads 176 of the container cap 164 is best shown in Fig. 3.
• the bottle cap need not be limited to the container cap 164 and thus bottle caps other than the cap 164 may be coupled with the finish 140, without limitation.
• Fig. 4A is a cross-sectional view of an exemplary embodiment of a Carbonated Soft Drink (CSD) container cap 180 which may be used to seal pressurized contents within the container 100.
• CSD Carbonated Soft Drink
• the CSD container cap 180 comprises a multiplicity of threads 176 suitable for rotatably engaging with the threads 172 of the finish 140.
• a seal 188 within the cap enters into the opening 144 and is placed into a pressed relationship with the first edge 152.
• Fig. 4B is a cross- sectional view of an exemplary embodiment of a Hot Fill container cap 184.
• the container cap 184 is substantially similar to the container cap 180, with the exception that the container cap 184 comprises a seal 192 which is taller than the seal 188.
• the seal 192 enters more deeply into the opening 144 than the seal 188.
• the first edge 152 is configured to tightly receive the seals 188, 192 into the opening 144 so as to retain the contents within the container 100 without leaking.
• the first edge 152 comprises two notches 196 disposed on opposite sides of the first opening 160.
• Each of the two notches 196 comprises a cross-sectional shape suitably formed so as to substantially reduce foaming of the contents when the container cap 164 is removed from the container 100.
• the cross- sectional shape of the notches 196 is a half-circle.
• one or both of the notches 196 may comprise cross-sectional shapes other than a half-circle, such as, by way of non-limiting example, various segments of circles, ellipsoids, ovals, rectangles, squares, triangles, V-shaped wedges, and any other cross-sectional shape which advantageously reduces foaming of contents when the container cap 164 is removed from the container 100.
• the cross- sectional shape of the notches 196 may be specifically designed so as to produce an audible tone or sound as pressurized gas exits the container 100 through the notches 196 when the container cap 164 is twisted.
• finish 140 is described herein specifically in connection with the container cap 164, the finish 140 is not limited to being coupled solely with the container cap 164, but rather any container cap that is suitably configured to engage with the finish 140, such that contents are sealed within the container 100, including but not limited to the CSD container cap 180 and the Hot Fill container cap 184, may be coupled with the finish 140 without detracting from the spirit and scope of the present disclosure.
• Such a drop in pressure may cause the contents within the container 100 to foam and potentially force the contents between the seal 188 and the first edge 152, and out of the container 100.
• the seal disengages from the two notches 196 before withdrawing from the rest of the first edge 152, thereby slowing down the pressure release occurring within the container 100.
• more slowly releasing pressure within the container 100 substantially reduces the likelihood that the contents will foam and push out of the container.
• slowly reducing internal pressure within the container 100 permits the use of additional carbon-dioxide content within the container, thereby increasing the shelf-life of the contents.
• the cross-sectional shape of the notches 196 need not be limited to those illustrated in Fig. 2, but rather various other cross-sectional shapes may be utilized for the notches 196.
• the number and positions of the notches 196 on the first edge 152 need not be limited to the number and positions illustrated in Fig. 2.
• the first edge 152 may comprise more than two notches 196.
• the first edge 152 may comprise one suitably configured notch 196.
• multiple notches 196 may be uniformly distributed around the circumference of the first edge 152.
• multiple notches 196 may be positioned around the circumference of the first edge 152 with a nonuniform spacing between the notches.
• Fig. 5 is a table 200 illustrating results observed during experimental testing performed in connection with applications of various embodiments of the present disclosure.
• suitably sized and shaped holes may be implemented in lieu of the notches 196. It is envisioned that the holes may be positioned just below the first edge 152 so as to be covered over by the seal 188 when the container cap 164 is tightly engaged with the container 100. It is further envisioned that the shape of the holes may be suitably designed to issue an audible sound when the container cap 164 is removed from the container 100 and pressure is relieved from the interior of the container. In some embodiments, the shape of each hole may be fashioned to resemble a flute, or a reed, which vibrates when the container cap 164 is removed from the container, thereby amplifying the audible sound as pressure within the container 100 is relieved.
