Description

This application claims the benefit of US Provisional Application No. 61 / 530,908, filed Sep. 2, 2011, which is incorporated herein by reference in its entirety.
Bottled beverages, including water, carbonated beverages and juices, are a multi-billion dollar global industry. The primary container used for the storage and sale of such beverages is a plastic bottle. Plastic bottles have thus become widely used due to a variety of factors including low cost, light weight, ease of use, and durability. Plastic bottles are usually closed at the top with a plastic cap, usually with some type of safety seal. The cap can be removed by twisting or flipping to expose the beverage inside the bottle. Often, such caps include a movable valve, such as a sports bottle cap, that allows an individual to seal the bottle and use the movable valve as a drinking aid similar to a straw. to enable.

  Water-soluble drink mixes are widely used commercially. Often in tablet or powder form, these mixes allow consumers to make a beverage by simply adding water. The consumer weighs the indicated amount or desired amount of mix for water to make a beverage. Such mixing is impractical for commonly found plastic water bottles because it is difficult to introduce the powder through a narrow opening. It can be easier to do this indoors (using a small funnel), but it is extremely difficult when traveling or during outdoor activities such as hiking. Furthermore, such “outdoor” mixing requires the consumer to carry the bottle and drink mix separately. Also, it is easy to inaccurately measure the amount of water or drink mix, thus creating a beverage that is too thick or too light.

  It is well known in the art that beverage additives such as vitamins, nutrients, and other supplements become unstable when suspended in a liquid such as water. The efficacy of such beverage additives decreases over time in water. As a result, beverage manufacturers “overstrengthen” such beverages by adding extra vitamins, nutrients, and other supplements to ensure a minimum potency level when consumed or expired. There must be. This creates additional raw material costs for the beverage producer, greatly reduces the shelf life of the beverage, and leaves consumers with uncertainty about the efficacy or nutritional value of such beverages.

  The general concept of the top of a bottle or container with a storage reservoir for beverage additives is well known in the art. Various means have been described in the art. However, some may have one or more undesirable aspects.

  Aspects of the techniques described herein relate to a cap, the cap preferably including a first part that includes a piercing element and a second part that includes a chamber with a bottom seal, Is configured to receive a piercing element, which pierces the bottom seal as the first and second parts rotate relative to each other.

  Another aspect of the technology described herein relates to a cap that includes a first hollow portion that is capped at one end thereof and a pierceable seal that closes the one end thereof. Axially opposite the capped end so that the first hollow portion is slidably received therein and the pierceable seal defines a closed reservoir therebetween The second hollow portion and a lock retainer that holds the two hollow portions in a rotationally fixed relation with respect to each other, and when the lock retainer is unlocked, the first hollow portion Allows rotation with respect to the second hollow part and allows the engagement of the locking means, so that the uncapped end of the first hollow part at least partly pierces the seal. Allows you to push away.

  Another aspect of the technology described herein relates to a method for forming a cap that includes a first protrusion and a first recess on its outer diameter at one end thereof. Forming a capped first hollow portion and having a pierceable seal closing one end thereof, the first hollow portion being slidably received therein, Forming a second cavity that is axially opposite the capped end so that a possible seal defines a closed reservoir between them; and Forming a second protrusion surrounding the inner diameter, forming a second recess to receive the first protrusion therein, and a first between the two hollow portions By forming the annular space and engaging the second protrusion and the first recessed portion, the first annular space is closed. Forming a breakable annular seal arranged to hold the two hollow portions in a rotationally fixed relationship, and the first protrusion within the second recess Receiving and allowing the first hollow portion to rotate relative to the second hollow portion so that the uncapped end of the first annular portion pushes the pierceable seal by rotation. Forming an annular portion disposed surrounding and securely attached to the outside of the second hollow portion so as to define a second annular space therebetween, and the second hollow portion Extending around the inner diameter of the third annular portion so as to engage the bottle neck in the second annular space and place a pierceable one in the bottle during rotation of the first hollow portion relative to Forming a thread.

  The present technology relates to devices, systems, and methods for making caps. Each device, system, and method may include one or more embodiments in any combination. Features of any embodiment can be used in combination with any other embodiment. Furthermore, the use of the terms “top” and “bottom” is not intended to limit the orientation of any element (s), but is used for convenience of discussion only.

  Embodiments of the present technology relate to a bottle cap with a storage compartment, which may also be referred to as a cap with a storage section. As illustrated in FIGS. 1A-1D, the bottle cap is preferably comprised of a first part 70 and a second part 5 that are configured to interlock together. The first part 70 and the second part 5 can be hollow. As shown in FIG. 1A, the first part 70 can be a top piece 70 and the second part 5 can be a bottom piece 5. The bottom piece 5 includes a chamber 16 for receiving the top piece 70, a bottom seal 25 (also referred to as a pierceable seal 25), a surface for securing to a screw cap container, a screw cap seal, and / or A lock seal may be included. The top piece 70 may include a first hollow or reservoir 10 for receiving and storing beverage additives. The reservoir 10 of the top piece 70 can be of a shape that allows the reservoir 10 to function as a piercing element 75 for breaking the seal. Either piece can be composed of an opaque material that can block any light that degrades the beverage additive. When the two pieces are mated together, multiple seals can be formed to prevent deterioration of the beverage additive due to heat, moisture, air, and other environmental factors. The seal further prevents the fluid in the bottle from prematurely mixing with the beverage additive. Both pieces can be made from a material such as plastic through injection molding or a similar process. Other materials, including but not limited to polymer resins, paper, glass, rubber, silica, carbon, metal, or combinations of these materials (including plastics) to achieve the benefits herein. Can be used.

  In some embodiments, the piercing member 75 and the bottom seal 25 may cause the piercing member 75 to rotate at least a portion (or some of the bottom seals 25) by rotating the top piece 70 and the bottom piece 5 relative to each other. In this embodiment, all are configured to be perforated. Thus, the bottom seal 25 can be pierced by a simple rotating or twisting movement of the piercing element 75 without having to push the top piece 70 into the bottom piece 5. One advantage of such a cap is that any additional space between the top piece and the bottom piece 5 to prevent downward movement of the piercing element 75 which causes premature failure of the bottom seal 25. No separator is required. This can reduce the amount of material used and eliminate the additional step of removing the space separator before the piercing element 75 pushes the top piece 70 to break the bottom seal 25. You can also.

  As shown in FIG. 2A, in some embodiments, the piercing member 75 extends below somewhere in the bottom seal 25 before twisting the top piece 70 and the bottom piece 5 against each other. Rather, as shown in FIGS. 2B and 2C, it may be shaped or disposed to extend below at least a portion of the bottom seal 25 after twisting. For example, the piercing element 75 and the bottom seal 25 may have similar shapes on their respective sidewalls such that the piercing element 75 and the bottom seal 25 have a corresponding or matching taper or angle before twisting. Can be configured. For example, the bottom seal 25 can have a taper / angle that is similar to or coincident with the taper / angle based on the shape of the sidewall, ie, the taper / angle of the piercing element 75 based on the shape of the sidewall. Rotating or twisting the top piece 70 with respect to the bottom piece 5 causes a portion of the side wall of the piercing element 75 (eg, the longer side wall of the piercing element 75) to be below at least a portion of the bottom seal 25. Extending to the side, thereby piercing the bottom seal. In other embodiments, the taper or angle of the piercing element 75 and the bottom seal 25 may not be the same, but the rotation of the piercing element 75 nevertheless causes the hole in the bottom seal 25 to be at least a portion of the piercing element 75. To open.

  Alternative drilling techniques using a rotating / twisting cap can be used as well. In addition, the taper and angle of the piercing element 75 relative to the bottom seal 25 can vary and is not limited to the embodiments or examples depicted herein. Any structure, method, and / or system is contemplated in which the piercing element 75 punctures the bottom seal 25 when the top piece 70 / piercing element 75 is rotated or twisted.

  As illustrated in FIG. 3, the interface between the top piece 70 and the bottom piece 5 can be a locking mechanism, such as a lock retainer 55, which can be a mutually locked top piece 70 and bottom piece. The pieces 5 are prevented from inadvertently moving relative to each other in the absence of applied force or before twisting / rotating. For example, the lock retention feature may prevent the top piece 70 and the bottom piece 5 from rotating relative to each other until the user applies a twisting motion to break or release the locking mechanism, after which the top piece and the bottom piece The pieces 5 are no longer locked together by the locking mechanism. A rotating or twisting motion can be applied to either cap.

  In some embodiments, the locking mechanism includes one or more releasable or breakable “teeth” that interconnect the top piece and bottom piece 5 thereby preventing their free rotation relative to each other. May be included. Upon application of sufficient torsional force, one or more “teeth” are released or destroyed, so that the locking mechanism no longer prevents the top piece 70 and the bottom piece 5 from rotating relative to each other.

  In some embodiments, the bottom seal 25 does not require a line of weakness. In other words, the bottom seal 25 may have a relatively uniform strength / material throughout it, but can still be pierced by the hollow piercing element 75.

  As shown in FIG. 1A, in some embodiments, the top piece 70 includes first and second sidewalls 12 and 14 of different lengths, thereby tapering the bottom of the piercing element 75. Alternatively, an angled circular edge 100 is created. For example, the top piece 70 represented in FIG. 1A represents a cross-sectional view of the top piece 70, and FIG. 1B depicts an external view of the top piece 70. The top piece 70 comprises a hollow piercing element 75 formed by the outer wall 80 and has an angled circular edge 100 at the bottom of the piercing element 75. The angled circular edge 100 is such that, for example, when the lock retainer 55 is released or broken by the twisting movement of the top piece 70 and the top piece 70 rotates relative to the bottom piece 5, the angled circular edge 100 is at the bottom. The inclination angle is such that the seal 25 is broken and the bottom seal 25 is at least partially (or entirely) pierced and opened.

  In some embodiments, due to the taper / shape of both the piercing element 75 and the bottom seal 25, the bottom seal 25 is completely separated from the bottom portion even when the top piece and bottom piece are fully rotated relative to each other. I will not let you. In such an embodiment, the piercing element 75 no longer extends below the bottom seal 25 as it approaches its initial position due to the taper matching the bottom seal 25. Accordingly, the piercing element 75 does not pierce that portion of the bottom seal 25 as it approaches its initial position. This allows the bottom seal 25 to remain at least partially attached to the bottom portion, thereby preventing the bottom seal from falling into the container.

  The amount of rotation or twist required to break the bottom seal 25 can be varied and is not limited to any particular amount. For example, the rotation that breaks the seal can be 90 degrees, 180 degrees, or 340 degrees. Alternatively, the rotation that breaks the seal can be anywhere from 1 degree to 360 degrees.

  In some embodiments, the amount of rotation after releasing the locking mechanism may be limited by another structural feature on the top piece and / or the bottom piece 5. Such a structure can inhibit rotation of the top piece 70 relative to the bottom piece 5 after exceeding a certain amount, even after releasing the locking mechanism. In other embodiments, no such limiting structure exists or is required, so that the top piece and the bottom piece 5 can rotate freely relative to each other after releasing the locking mechanism.

  In some embodiments, the bottom piece 5 also includes a separate locking mechanism, such as a lock retainer 65, to prevent accidental rotation of the bottom piece 5 relative to the container to which it can be connected. The lock retainer 55 mechanism may also include one or more “teeth” as previously described. During the rotation of the bottom piece 5 with respect to the container, the lock maintaining mechanism 55 is released, for example by breaking or releasing the “teeth”, thereby allowing free rotation of the bottom piece 5 with respect to the container.

  In some embodiments, the bottom piece 5 further comprises an outer wall or protrusion 48 that allows the bottle cap 1 to be screwed to the bottle 160 by a ring or thread 35. The top piece 70 can also include a protrusion 18.
