FIEL
100021 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 that occurs with carbonated soft drink containers.
ACKGROUND
[0003] Plastic 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 forces exerted on the walls of the container by their contents. PET resins are also reasonably priced and easy to process.
PET bottles generally are made by a process that includes blow-molding of plastic pre-fauns that have been made by injection molding of the PET resin.
100041 A drawback to plastic containers is that those containing 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 clothing 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 leads to a decreased longevity of the flavor profile of the carbonated 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 so as to increase the longevity of the flavor profile of the contents.

The invention should be understood to not be limited to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure.
DETAILEI DESC ' PTI 1 N
[0025] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one of ordinary skill in the art that the invention disclosed herein may be practiced without these specific details.
In other instances, specific numeric references such as "first notch," may be made. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that the "first notch" is different than a "second notch." Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present disclosure. The term "coupled"
is defined as meaning connected either directly to the component or indirectly to the component through another component. Further, as used herein, the terms "about," "approximately," or "substantially" for any numerical values or ranges indicate a suitable dimensional tolerance that allows the part or collection of components to function for its intended purpose as described herein.
[0126] In general, the present disclosure describes an apparatus and a method for a finish configured to define an opening to an interior of a container and to substantially reduce foaming of contents when the container is opened. The finish comprises a cylindrical body including a peripheral portion with a first edge and a second edge disposed at opposite ends. The first edge defines an opening and is configured to receive a container cap. Generally, the first edge is configured to receive a seal of the container cap. The second edge is configured to receive a neck of the container such that the opening is in fluid communication with an interior of the container.
One or more threads on an exterior of the peripheral portion are configured to rotatably engage with one or more threads of the container cap. At least one notch is disposed at the first edge, peripheral to the first opening, and comprises a cross-sectional shape suitably formed to substantially reduce foaming of the contents. In one embodiment, the first edge comprises two notches, disposed on opposite sides of the finish, wherein the cross-sectional shape of each of the notches comprises a half-circle configured to substantially reduce foaming of the contents.
[0027] Figure 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. Preferably, the base 104 is of the petaloid variety, although other configurations of the base may be incorporated into the container 100, without limitation.
The grip portion 108 comprises a generally smooth, cylindrical portion of the container 100 suitable for affixing a label, as well as providing a location for grasping the container. In some embodiments, the grip portion 108 may comprise one or more sidewall ribs that generally may vary in depth, and may swirl or angulate around the grip portion 108.
Additional configurations of the grip portion 108 are disclosed in U.S. Patent Application, entitled "Plastic Container with Strapped Base," filed on January 16, 2014, having application serial number 14/157,400, the entirety of which application is incorporated by reference herein.

[0028- In the illustrated embodiment, the grip portion 108 transitions into a shoulder 124, which connects to a bell 128. Although the bell 128 illustrated in Fig. 1 is smooth and generally unornamented, in other embodiments the bell may include design features, such as, by way of non-limiting example, a plurality of scallops. The bell 128 connects to a neck 136, which connects to a Carbonated Soft Drink (CSD) 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 CSD finish 140. The CSD finish 140 may be adapted to receive a closure to seal contents in the container 100, such as, by way of non-limiting example, a container cap 164 or a bottle cap.
The CSD finish 140 generally defines an opening that leads to an interior of the container 100 for containing a beverage, or other contents.
[0029] Figure 2 illustrates an upper perspective view of an exemplary embodiment of the CSD
finish 140 that is configured to substantially reduce foaming of contents, particularly carbonated contents, during opening of the container 100. The CSD 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 an opening 160 and is configured to receive a plug seal 168 within the container cap 164, as disclosed herein. The second edge 156 is configured to receive the neck 136 of the container 100, as shown in Figs. 1 and 2, such that the opening 160 is in fluid communication with the interior of the container 100 once the CSD
finish 140 is installed thereon.
[0030] 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. A plurality of gaps 174 are disposed in the threads and positioned uniformly around the perimeter of the cylindrical body 148. Preferably, the gaps 174 of adjacent threads 172 are vertically aligned so as to form channels 178 extending longitudinally along the CSD finish 140. The channels 178 advantageously operate to relieve pressure within the container 100 when the container cap 164 is loosened. As will be appreciated, the channels 178 provide a direct route for gases escaping the interior of the container 100, rather than the gases being forced to travel around the finish between adjacent threads 172.

[0031] An engagement of the threads 172 of the CS lk finish 140 with the threads 176 of the container cap 164 is best shown in Fig. 3. It should be borne in mind, however, that 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 CSD finish 140, without limitation. As such, Fig. 4A
illustrates a cross-sectional view of an exemplary embodiment of a CSD container cap 180 that may be used to seal pressurized contents within the container 100. The CSD container cap 180 comprises a multiplicity of threads 176 suitable for rotatably engaging with the threads 172 of the CSD finish 140. Gaps 174 disposed in the threads 176 serve to vent pressurized gases escaping the container 100 when the cap 180 is loosened. During tightening of the container cap 180, a plug seal 188 within the cap enters into the opening 160 and is placed into a pressed relationship with the first edge 152. Further, Fig. 4B
illustrates a cross-sectional view of an exemplary embodiment of a Hot Fill container cap 184.
The Hot Fill container cap 184 is substantially similar to the CSD container cap 180, with the exception that the container cap 184 comprises a plug seal 192 which is taller than the plug seal 188. Thus, during tightening of the Hot Fill container cap 184 onto the CSD
finish 140, the plug seal 192 enters more deeply into the opening 160 than the plug seal 188. It will be appreciated that the first edge 152 is configured to tightly receive the plug seals 188, 192 into the opening 160 so as to retain the contents within the container 100 without leaking.
[00321 In the embodiment illustrated in Fig. 2, the first edge 152 comprises two notches 196 disposed on opposite sides of the opening 160. Although the notches 196 are aligned with two of the channels 178 in the embodiment illustrated in Fig. 2, in other embodiments the notches 196 may be positioned anywhere around the opening 160, as desired. Each of the two notches 196 comprises a cross-sectional shape suitably foimed so as to substantially reduce foaming of the contents when the container cap 164 is loosened with respect to the CSD finish 140. In the illustrated embodiment, the cross-sectional shape of the notches 196 is a half-circle. In other embodiments, however, 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 that is found to advantageously reduce foaming of contents when the container cap 164 is removed from the container 100.

[0033] In some embodiments, the cross-sectional shape of the notches 196 may be specifically designed so as to produce an audible tone or sound as pressurized gases exit the container 100 through the notches 196 when the container cap 164 is loosened. Moreover, it should be understood that although the CSD finish 140 is described herein specifically in connection with the container cap 164, the CSD 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 CSD 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 CSD finish 140 without detracting from the spirit and scope of the present disclosure.
[0034] When the container cap 164 is tightly engaged with the CSD finish 140, as shown in Fig. 3, the plug seal 168 and the first edge 152 cooperate so as to prevent pressurized contents from leaking out of the container. When the container cap 164 is loosened, generally by twisting so as to loosen the engagement between the threads 172 and 176, the seal 188 is withdrawn from the first edge 152. In absence of the two notches 196, withdrawing the plug seal 168 from the first edge 152 causes an abrupt drop in pressure within the container 100 to an ambient atmospheric pressure. Such a drop in pressure may cause the contents within the container 100 to foam and potentially force the contents between the plug seal 168 and the first edge 152, and out of the container 100. In the embodiment illustrated in Fig. 3, however, as the plug seal 168 is withdrawn from the CSD finish 140, 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. As will be appreciated, more slowly releasing pressure within the container 100 substantially reduces the likelihood that the contents will foam and push out of the container.
Those skilled in the art will further appreciate that slowly reducing internal pressure within the container 100 peiiiiits the use of additional carbon-dioxide content within the container, thereby increasing the longevity of the flavor-profile of the contents.
[0035] As mentioned above, 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. Further, 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. Thus, in some embodiments, the first edge 152 may comprise more than two notches 196. In other embodiments, the first edge 152 may comprise one suitably configured notch 196. In some embodiments, multiple notches 196 may be uniformly distributed around the circumference of the first edge 152. In some embodiments, multiple notches 196 may be positioned around the circumference of the first edge 152 with a non-uniform spacing between the notches. Accordingly, Fig. 5 is a table 200 illustrating results observed during experimental testing performed in connection with applications of various embodiments of the present disclosure.
[0936] In some embodiments, 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 plug seal 168 when the container cap 164 is tightly engaged with the CSD finish 140. 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 CSD
finish 140 and pressure is relieved from the interior of the container 100. 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 100, thereby amplifying the audible sound as pressure within the container is relieved.
[0037] Figures 6A through 6C illustrate perspective views of an exemplary embodiment of a container cap 204 and a liner seal 208 coupled with a CSD finish 212, in accordance with the present disclosure. As best shown in an exploded view illustrated in Fig. 6C, the liner seal 208 is disposed between the container cap 204 and the CSD finish 212. When the container cap 204 is tightly engaged with the CSD finish 212, the liner seal 208 operates similarly to a gasket that prevents pressurized contents from leaking out of the container 100. The CSD
finish 212 is substantially similar to the CSD finish 140, with the exception that the CSD
finish 212 may comprise one or more threads 172 that are configured specifically to engage with the threads within the container cap 204.
[00381 As shown in Fig. 6B, the liner seal 208 may be affixed to the first edge 152 by way of any of various suitable adhesives, or the liner seal 208 may be of the variety that is adhered to an inside of the container cap 204. As will be recognized, the liner seal 208 preferably has a thickness suitable to fill and seal the notches 196 so as to prevent pressurized contents from leaking out of the container 100. Thus, when the container cap 204 is loosened with respect to the CSD finish 212, the liner seal 208 loosens within the notches 196 before loosening from the first edge 152.
As disclosed herein, venting pressurized gases through the notches 196 before unsealing the entirety of the first edge 152 substantially reduces the tendency for carbonated contents to foam and push out of the container 100. Coupling the liner seal 208 with the CSD
finish 212 permits using a relatively greater carbon-dioxide content within the container so as to increase the longevity of the flavor-profile of the contents.
[0039] While the invention has been described in terms of particular variations and illustrative figures, those of ordinary skill in the art will recognize that the invention is not limited to the variations or figures described. In addition, where methods and steps described above indicate certain events occurring in certain order, those of ordinary skill in the art will recognize that the ordering of certain steps may be modified and that such modifications are in accordance with the variations of the invention. Additionally, certain of the steps may be performed concurrently in a parallel process when possible, as well as performed sequentially as described above. To the extent there are variations of the invention, which are within the spirit of the disclosure or equivalent to the inventions found in the claims, it is the intent that this patent will cover those variations as well. Therefore, the present disclosure is to be understood as not limited by the specific embodiments described herein, but only by scope of the appended claims.
