Abstract
A reusable closure device is secured to an engagement member on the nozzle of a container. The device has a stopper which can partially abut the nozzle. The stopper is connected by one or more hinge members to a sleeve. The sleeve has a retaining member which engages the engagement member. The hinge members allow the stopper to pivot about the nozzle from a closed position, which forms a leak-proof and air tight seal, to an open position, which allows access to the container contents.
Description
- The present invention relates to a reusable closure for providing access to the contents of a container without the necessity of completely removing the closure.
- Bottled beverages such as water, juices, carbonated beverages, iced tea, and alcoholic beverages are stored in a wide variety of different containers such as cartons, bottles, flasks or jugs, made from materials including paper, plastic and glass. A large number of different types of closures for these containers have been utilized, including corks, crown caps, lids, snap-on caps, push-pull caps and screw caps. Bottled beverages typically are sold in plastic or glass bottles, with metal or plastic closures sealing the container. At present most plastic beverage bottles are fabricated using polyethylene terephthalate plastic (PET), which is generally clear, tough and provides a good barrier to gas and moisture.
- Beverage containers typically include a narrowing neck with an opening for access to the beverage therein. Typical closures which cover the container opening include metallic crown caps that require a bottle opener or other similar device to remove, metal or plastic screw caps, and pull up and push down type caps. With the exception of metallic crown caps, these closures are designed to be reusable such that the closure may be removed and replaced onto the container thereby allowing a portion of the beverage contained within the container to be consumed over a period of time.
- Such closures have been designed to address a number of concerns, which include spillage, evaporation, retention of carbonation and ease of use. Spoilage is a particular concern with certain beverages, as prolonged contact with air is the primary cause of spoilage.
- A significant disadvantage associated with these closures is the requirement that the closure be completely removed in order to gain access to the container. This creates the risk that the closure will be discarded or misplaced.
- Several attempts have been made to develop reusable container closures with limited success. U.S. Pat. No. 184,908 to Root is an early example. Root discloses a container closure consisting of a spherical stopper, perforated with an aperture, firmly secured to a bottle by means of a wire yoke or other rigid material, a pintle and two projecting trunnions. By rotating the spherical stopper a quarter turn about the pintle, the aperture is aligned with the nozzle of the bottle, allowing access to the contents stored within. The yoke allows the rotation of the sphere about the pintle's axis. Access to the entire nozzle opening is not possible with this closure.
- The reusable container closure of U.S. Pat. No. 5,104,008 to Crisci engages a bottle such as a blow moulded water bottle. These types of reusable container closures are commonly referred to as push-pull caps, and are frequently used by energy and sports beverage providers. The contents stored within the bottle are accessed by pulling a movable spout vertically into its “open” position. When placed in the open position, the contents stored within are dispensed through an opening located at the top of the movable spout. The bottle is re-sealed by pushing the movable spout into its “closed” position. An empty bottle may be refilled by removing a tear tab, prying the closure off the bottle, filling the bottle and prying the closure back on. Repeated use of this closure with multiple water bottles or bottles having various nozzle diameters or configurations is not contemplated.
- The two-part reusable container closure of U.S. Pat. No. 6,264,051 to Reidenbach consists of a hinged cap attached to a sleeve containing internal threads for twisting the closure onto a threaded bottle. The contents stored within the container are accessed by partially unscrewing the closure until the hinged threaded cap portion is released. This closure is for use with a specific threaded bottle as the internal threads of the closure must engage the external threads of the nozzle.
- A need exists for an improved reusable container closure that can be coupled to various types of containers which addresses the limitations of the prior art.
- In accordance with the present invention, a reusable container closure is provided for providing access to the container contents without the necessity of completely removing the closure and thereby subjecting the closure to loss or damage, and the contents of the container to spillage, spoilage, evaporation and contamination.
- In one embodiment of the present invention, there is provided a reusable closure device which can be secured to the nozzle of a container, such as a bottle. Bottles used with the device include a standard polyethylene terephthalate beverage bottle.
- The nozzle has at least one engagement member, such as an annular flange, to allow the device to be secured thereon. The device comprises a stopper formed of a flexible and resilient material. The stopper has a non-abutting portion which does not contact the bottle neck and an abutting portion which is adapted to contact the bottle neck. The stopper is joined to one or more flexible, elastic and resilient hinge members at one end. At the other end, the hinge member(s) extend to and join a sleeve. The sleeve, which may be in the form of a ring or a resilient clamp, comprises a retaining member which is adapted to engage the engagement member of the nozzle. The hinge members are adapted to allow the stopper to pivot about the nozzle. The abutting portion of the stopper is adapted to form a leak-proof, air tight seal when it abuts the nozzle.
- If the device has one hinge member, it may be in the shape of a membrane which extends from the stopper to the sleeve. If the device has two or more hinge members, the members extend between the stopper and the sleeve such that they allow the stopper to pivot about the nozzle.
- In another embodiment, the sleeve further comprises a gripper tab which is adapted to aid in the removal of the device from the container. For devices having a ring-shaped sleeve, the gripper can be located anywhere on the sleeve. For devices having a clamp sleeve, the gripper is preferably located opposite the clamp opening.
- The stopper may be generally spherical or hemi-spherical in shape. The abutting portion of hemi-spherical shaped stoppers is not on the flat portion of the hemi-sphere.
- In another embodiment, aesthetic accessories may be releasably engaged to the stopper at the non-abutting portion.
- In another embodiment, the stopper further comprises a generally vertical cylindrical opening and a normally closed valve which closes the opening, such that the valve can receive a drinking straw.
- In other embodiments, the stopper can be made of regulatory approved food grade silicon rubber, regulatory approved food grade natural resins, and regulatory approved food grade synthetic resins.
- In other embodiments, at least one of the stopper, retaining member, and resilient hinge members comprises a food grade additive that imparts an aroma.
- In another embodiment, the stopper and/or the gripper comprise a hard plastic portion formed using co-injection mould techniques.

- Referring to
FIGS. 2 and 3 , perspective views of an embodiment of the present invention attached to a container or beverage bottle such as a standard PET beverage bottle in the closed position are shown. The nozzle ofbottle 150 comprises a threadedcap portion 155, an upperannular flange 158 and a lowerannular flange 160.Annular flange 158 is adapted to restrain and detach the safety seal (not shown) of a standard twist bottle cap. The radius ofannular flange 160 is typically greater than the radius ofannular flange 158 and is spatially positioned onbottle 150 to restrain the safety seal in place once the seal is broken. The reusable container closure of the present invention is attached to bottle 150 by inserting threadedcap portion 155 ofbottle 150 intoring portion 125. As threadedcap portion 155 is inserted intoring portion 125, retainingmember 130 is compressed byannular flange 160 until retainingmember 130 has clearedannular flange 160. In this manner,annular flange 160 is an engagement member since it engages retainingmember 130 ofring portion 125. The safety seal from the bottle cap may or may not be located betweenannular flanges portion 115 ofstopper 100 abuts the upper perimeter of threadedcap portion 155.Hinge members 120 exert sufficient force to circumferentiallydeform abutting portion 115 ofstopper 100 in contact withcap portion 155 so as to form a liquid leak-proof and airtight seal. - The reusable container closure is easily adaptable to non-standard PET beverage bottles, such as bottles with crown or screw caps that comprise at least one engagement member located near the nozzle. In this embodiment, the circumference of retaining
member 130 is adjusted such that at least one engagement member on the nozzle of the bottle is sufficient to engage retainingmember 130. Typically the engagement member is an annular flange, although those skilled in the art will appreciate that other protrusions or sharp changes in curvature on the neck of non-standard bottles may also function as an engagement member. - The reusable container closure is easily removed from
bottle 150 when the stopper is in the open position by grasping and pullinggripper 135 in a generally vertical direction away frombottle 150, such thatring portion 125 disengagesannular flange 160, thereby allowing retainingmember 130 to decompress reversing the above described attachment process. Thegripper 135 can be located anywhere onring portion 125. - In the closed position, the height that the reusable container closure extends above
bottle 150 is relatively small, typically about 1 inch above the top surface of threadedcap portion 155. This allows for convenient storage inside a refrigerator, without requiring to increase the shelf height. In addition, the reusable container closure is compatible and does not interfere with beverage bottle holders on bicycles and other recreational vehicles. - The reusable container closure of the present invention is opened by applying sufficient force to
stopper 100 in a generally horizontal direction away frombottle 150 until abuttingportion 115 ofstopper 100 is no longer in direct contact with the surface ofcap portion 155, as shown inFIG. 4 . Asstopper 100 is retracted fromcap portion 155,elastic hinge members 120 are actuated to pivotstopper 100 approximately 90° aboutcap portion 155, thereby allowing access to the beverage contained withinbottle 150. When the reusable container closure is in the open position, as shown inFIGS. 5 and 6 , hingemembers 120 exert sufficient force to firmlysecure stopper 100 against the threaded portion ofcap portion 155. As such,bottle 150 is freely movable in the open position withstopper 100 firmly secured, thereby providing clear access to the contents ofbottle 150. -
Hinge members 120 are of sufficient thickness to permit repeated openings and closings without breakage.Hinge members 120 may be circular in cross section, although any shape can be utilized, and are approximately 3/16 inch in diameter. - In another embodiment,
sleeve portion 125,fasteners 105 and hingemembers 120 are fabricated from the same material asstopper 100 using injection molding techniques. This permits the various elements of the reusable container closure to be integrally formed with the other portions, includingstopper 100 and retainingmember 130. - A reusable container closure according to another embodiment of the invention is shown generally in

In the illustrated embodiment,fasteners 205 and hingemembers 220 attach thestopper 200 to clampportion 225.Clamp portion 225 is fabricated from resilient material such as moulded plastic.Clamp portion 225 is generally C-shaped with an opening and adapted to encircle the neck ofbeverage bottle 250, such as a standard PET beverage bottle, by engaging an engagement member onbottle 250 such asannular flange 260. - Optionally,
clamp portion 225 also comprisesgripper 235. Thegripper 235 is preferably located onclamp portion 225 opposite the opening to maximize the effect of a lateral force ongripper 235 when disengaging the device of this embodiment frombottle 250. - The closure of this embodiment is attached to bottle 250 by positioning the opening of
clamp portion 225 adjacent to the neck portion ofbottle 250 belowannular flange 260. Sufficient force is applied in a generally lateral direction againstclamp portion 225, thereby expanding the opening ofclamp portion 225. Once the opening ofclamp portion 225 exceeds the diameter of the neck ofbottle 250, the neck ofbottle 250 passes through the opening andclamp portion 225 contracts to encircle the neck ofbottle 250 as shown inFIG. 8 . - The reusable container closure is easily removed from
bottle 250 by applying sufficient force to clampportion 225, such thatclamp portion 225 expands, thereby allowing the neck ofbottle 250 to pass through the opening reversing the above described attachment process. - In embodiments that comprise
gripper 235, the reusable container closure is easily removed frombottle 250 by grasping and pullinggripper 235 in a generally lateral direction away frombottle 250, such thatclamp portion 225 expands, thereby allowing the neck ofbottle 250 to pass through the opening reversing the above described attachment process. - A reusable container closure according to another embodiment of the invention is shown generally in
