Description

CARBONATED SOFT DRINK FINISH MODIFICATION

PRIORITY [0001] This application claims the benefit of and priority to U.S. Patent Application No. 14/938,596 filed onNovember 11, 2015 and U.S. Provisional Application, entitled “Carbonated Soft Drink Finish Modification,” filed on November 13, 2014 and having application serial number 62/079,431.

FIELD [0002] 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.

BACKGROUND [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 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.

[0004] 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 carbondioxide 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. There is a need for 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.

2015346342 31 Jan 2020 [0005] Alternatively or additionally, there is a need to at least provide the public with a useful choice.

SUMMARY [0006] The present invention provides 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 comprising: a cylindrical body comprising a peripheral portion with a first edge and a second edge disposed at opposite ends, the first edge defining a first opening and configured to receive a container cap, the second edge defining a second opening and configured to receive a neck of the container, wherein the first and second openings are in fluid communication; one or more threads on an exterior of the peripheral portion, the threads configured to rotatably engage with one or more threads of the container cap; and a plurality of notches disposed at the first edge, peripheral to the first opening, each notch comprising a cross-sectional shape suitably formed to substantially reduce foaming of the contents; wherein the plurality of notches comprises two notches disposed on opposite sides of the first opening, the cross-sectional shape of each of the two notches being a half-circle; the first edge is configured to receive a seal of the container cap and the seal is disengageable from the plurality of notches prior to withdrawing from the rest of the first edge, thereby slowing down the pressure release occurring within the container.

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.

DETAILED DESCRIPTION [0024] 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

2015346342 31 Jan 2020 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.

[0025] 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 a first 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 defines a second opening and is configured to receive a neck of the container. The first and second openings are in fluid communication. 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 first opening, wherein the crosssectional shape of each of the notches comprises a half-circle configured to substantially reduce foaming of the contents.

[0026] 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. 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

2015346342 31 Jan 2020 connects to a bell 128. In the embodiment illustrated in Fig. 1, 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.

[0027] 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.

[0028] As illustrated in Fig 2, 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. 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 maybe coupled with the finish 140, without limitation. As such, Fig. 4 A 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. The CSD container cap 180 comprises a multiplicity of threads 176 suitable for rotatably engaging with the threads 172 of the finish 140. During tightening of the container cap 180, a seal 188 within the cap enters into the opening 144 and is placed into a pressed relationship with the first edge 152. Further, Fig.

2015346342 31 Jan 2020

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. Thus, during tightening of the container cap 184 onto the finish 140, the seal 192 enters more deeply into the opening 144 than the seal 188. It will be appreciated that 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.

[0029] In the embodiment illustrated in Fig. 2, 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. In the illustrated embodiment, the cross-sectional shape of the notches 196 is a half-circle. In other embodiments, 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. 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 gas exits the container 100 through the notches 196 when the container cap 164 is twisted. Moreover, it is to be understood that although the 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.

[0030] It will be appreciated that when the container cap 164 is tightly engaged with the finish 140, as shown in Fig. 3, the seal within the cap, such as the seal 188, and the first edge 152 cooperate so as to prevent pressurized contents within the container 100 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

2015346342 31 Jan 2020

152. In absence of the two notches 196, withdrawing the seal 188 from the first edge 152 causes an abrupt drop in pressure within the container 100 to the 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 seal 188 and the first edge 152, and out of the container 100. In the embodiment illustrated in Fig. 2, however, as the seal 188 is withdrawn from the 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 permits the use of additional carbon-dioxide content within the container, thereby increasing the shelflife of the contents.

[0031] 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.

[0032] 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 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

2015346342 31 Jan 2020 is removed from the container, thereby amplifying the audible sound as pressure within the container 100 is relieved.

[0033] 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.

[0034] Throughout this specification and the claims which follow, unless the context requires otherwise, the word comprise, and variations such as comprises and comprising, will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.

[0035] The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.
