Definitions

  • Bottle caps are very common and used to seal the top of a bottle that can often contain a liquid. Unlike metal bottle caps that can be removed by being pried off (as used, e.g., in beer bottles and the like), many bottle caps are made of plastic and designed to be removable and replaceable, so that the bottle can be resealed after removing some of the contents, e.g., by pouring or drinking.
  • a common type of bottle cap consists of a simple round body with a solid upper surface and internal threads, which can be unscrewed to access the contents and then twisted back on to reseal the bottle.
  • Such bottle caps are common for bottles containing beverages and other liquids such as sauces or condiments.
  • These “twist-off’ caps provide a solid mechanical seal when closed and are suitable for containing pressurized contents, such as carbonated beverages (soda, seltzer water, and the like). However, they require twisting motions to unscrew the cap and screw it back on each time the contents are accessed, which is not very convenient.
  • Some bottle caps are permanently affixed to the top of the bottle but include a flip top that can be raised to access the contents.
  • the flip top is typically attached to the body of the cap by a flexible plastic strip or the like, such that the flip top can be opened or closed while remaining attached to the cap.
  • a common type of flip top cap includes a flip top that covers the entire upper surface of the bottle cap, including the upper perimeter thereof.
  • Such bottle caps often contain a solid surface below the flip top that encloses the entire top opening of the bottle, with a small hole through this surface.
  • the hole is typically about 1/4 inches in diameter.
  • a small peg or protrusion is formed as part of the lower surface of the flip top, and configured such that the peg blocks the small hole when the flip top is closed, and the small hole is opened to allow access to the bottle contents when the flip top is raised.
  • the flip top can remain secured when closed by friction, and an optional peripheral ridge can be provided so the flip top snaps closed and requires a bit of additional force to raise it, thereby reducing the likelihood of accidental opening and spillage.
  • Such flip tops are commonly used for household items such as shampoo and lotion bottles.
  • the small opening is not suitable for drinking or rapid pouring of the contents.
  • Such bottle caps can optionally be provided with threads that screw onto the top of the bottle, but again this requires unscrewing the entire cap to access the large bottle top opening, and rescrewing the cap on to reseal the bottle.
  • flip-top lids include a large flip top that again forms the entire upper surface of the cap, with a larger opening beneath it.
  • Such caps typically include ridges on the inside perimeter of the flip top that interact with further ridges formed near the upper perimeter of the bottle cap body. Such ridges can provide a mechanical seal that prevents the flip top from opening unless it is lifted from one edge with sufficient force to separate the connecting ridges.
  • Such flip tops can be used in milk bottles and the like. Although such flip tops are useful for sealing the contents of a bottle, they are poor at resisting internal pressure in the bottle, such as pressure from carbonated beverages, because the large area of the flip top tends to result in large upward forces on the flip top when the contents are pressurized. Such forces, which can be comparable to the lifting force needed to manually lift the flip top, can easily pop the top off accidentally.
  • flip top caps include those in which the flip top forms just a portion of the upper surface of the cap, with edges of the flip top creating seams on the upper surface of the cap.
  • Such flip tops can be provided with notches or grooves that couple with corresponding notches or grooves on or just below the adjacent cap surface, such that the flip top locks in place when it is pushed down fully, and can be opened by lifting an edge of the flip top with sufficient force.
  • Such caps are commonly used for bottles containing pills or tablets, and provide a large opening for better access to the contents. Again, such caps are not used for pressurized contents because the large area of the flip top would generate larger forces on the flip top that is exposed to the internal pressure of the contents, thereby leading to undesirable accidental opening of the flip top.
  • the present invention provides a bottle cap with a flip top that can be used to seal the contents of a bottle and provide easier access to the bottle contents than a conventional screw-on cap.
  • Exemplary bottle caps include an opening provided through the upper surface of the cap that spans only a portion of the top surface of the cap, and a flip top configured to fit precisely or conformally within the opening when closed and generate a reliable mechanical seal.
  • the flip top can be attached to the surface or body of the cap by a flexible hinge, and the flip top can be flush with the top of the cap when it is closed.
  • the inner perimeter of the opening and the outer perimeter of the flip top can each be provided with a plurality of ridges that are configured to interlock when the flip top is pressed closed onto the cap. Such interlocking ridges can provide a reliable mechanical seal to prevent leakage of the bottle contents or accidental opening of the flip top.
  • An edge of the flip top can be provided with a tab to facilitate lifting of the flip top to reveal the opening in the cap, where such tab can protrude slightly beyond the edge of the cap.
  • a recess in the upper surface or edge of the cap can be provided below the tab to further facilitate lifting of the tab and attached flip top.
  • the bottle cap can be formed from any type of plastic commonly used to make conventional bottle caps such as, e.g., PEI' (polyethylene terephthalate), HDPE (high-density polyethylene), LDPE (low-density polyethylene), or PP (polypropylene). Other types of plastics and/or other materials can be used to form the bottle cap or portions thereof in further embodiments. The entire cap may be formed from a single type of material, or different components or portions of the bottle cap can be formed from different materials. [0012] The bottle cap can be provided in any one of a variety of sizes, including the cap size commonly used for plastic beverage bottles that is about 1-1/8 inches in diameter.
  • the bottle cap can be provided in other sizes, including larger sizes, based on the opening size of the bottle it will be used for.
  • the opening in the top of the bottle cap (and corresponding shape of the flip top) can be provided in a substantially round shape, in a teardrop shape, in an oval or ovoid shape, or the like.
  • the area-to-perimeter ratio of the opening may be preferably less than about 3/16 inches for bottle caps made from conventional plastic materials, or optionally less than about 5/16 inches.
  • Such small area-to-perimeter ratios can provide sufficient interlocking forces between the edges of the opening and of the flip top to generate a reliable seal by the flip top when closed. For example, such ratios can be sufficient to reliably seal the flip top even when the contents of the bottle are pressurized, as with carbonated beverages.
  • Bottle caps may be provided with various configurations for securing them to bottles, including: threads for screw-on applications (where the bottle cap may optionally be provided with a permanent collar to prevent twist-off removal once installed, or may be removable like a conventional twist-off cap); a locking clamp around the lower perimeter of the cap that is configured to slide over and hook onto a ridge on the neck of a bottle when the bottle cap is pressed onto the top of the bottle, preventing its subsequent removal; or an attachment surface around the lower inside perimeter of the bottle cap body to facilitate adherence of the bottle cap to a bottle top using, e.g., adhesives, cements, plastic welding, thermal bonding, and the like.
  • threads for screw-on applications where the bottle cap may optionally be provided with a permanent collar to prevent twist-off removal once installed, or may be removable like a conventional twist-off cap
  • a locking clamp around the lower perimeter of the cap that is configured to slide over and hook onto a ridge on the neck of a bottle when the bottle cap is pressed onto the top of
  • the bottle cap according to the invention may have an opening that is tapered below the top surface of the bottle cap to provide better flow of the bottle contents when poured from the bottle with the flip lid raised.
  • the bottle cap according to the invention may also include a tamper-resistant seal or mechanism, such as detachably affixing the flip top to adjacent locations on the cap surface when the flip top is in the closed position.
  • Such attachment points can be formed using localized thermal fusion, plastic welding, adhesives, or the like, such that they will break easily when the flip top is lifted for the first time, providing visible and tactile feedback confirming that the flip top had not been opened previously.
  • a sealing film can also be provided that can be broken upon first opening of the flip top on the bottle cap.
  • Such tamperresistant sealing films can be made using thin films of foil, plastic, or the like.
  • a sealing film may be provided over the top opening of a bottle and adhered to the upper rim, prior to installing the flip-top bottle cap. Such film can be seen and easily punctured when the flip top is opened for the first time.
  • a sealing film can be adhered to the lower portion of the opening of the cap itself, covering the opening in the top of the cap from below, and can be punctured in a similar manner.
  • the sealing film may be adhered to the lower edges of both the opening and the bottom portion of the flip top. This configuration allows the sealing film to be broken automatically when the flip top is lifted up for the first time, tearing the sealing film away from the bottom edges of the opening.
  • Such sealing film can cover the entire bottle cap opening under the flip top, or it can be provided as a thin strip that seals only the gap between the lower edges of the flip top and the lower edges of the opening in the top of the bottle cap.

  • the entire cap 100 can be formed of a single material, e.g., by an injection molding process or the like. Alternatively, the hinge can be formed of a different material from the bottle cap and/or flip lid.
  • the bottle cap 100 includes an upper surface 120 of the cap body that contains an opening 160 therethrough, which facilitates access to the contents of the bottle when the flip top 130 is raised or opened.
  • the flip top 130 is shaped and configured to completely cover the opening 160 when it is closed, forming a seal on the bottle cap 100 to prevent escape of the bottle contents.
  • the opening 160 extends over only a portion of the upper surface 120 of the bottle cap 100.

  • a recess 150 may be provided in the upper surface 120 of the bottle cap 100, adjacent to the opening 160. Such recess 150 can be located under or proximal to the tab 140 when the flip top 130 is in the closed or sealed position. The recess 150 can facilitate access to the tab 140, e.g., to make it easier to lift the flip top 130 by the tab 140 to access the bottle contents.
  • the tab 140 may protrude slightly from the edge of the upper surface 120 to also facilitate lifting of the flip top 130 by the tab 140
  • the lower surface of the flip top 130 includes a seal 175 that is shaped to fit precisely within the opening 160 when the flip top 130 is closed.
  • the seal 175 can be formed as a continuous wall protruding from the bottom of the flip top 130. This exemplary configuration can provide desirable sealing properties of the flip top 130 without requiring a lot of material to form the bottle cap 100.
  • the seal 175 can be provided as a solid protrusion extending from the bottom of the flip top 130, such that the center of the flip top 130 is thicker than its perimeter outside the seal 175. This may provide more structural stability for sealing the opening 160 but would require additional material e.g., plastic) to form the flip top 130.
  • the outer perimeter of the seal 175 can be provided with one or more continuous ridges 170.
  • Corresponding continuous ridges 180 can be provided along the inner wall of the opening 160.
  • the ridges 170 can be clearly seen in the side view of FIG. 1C.
  • the ridges 170, 180 can be configured to interlock and provide a strong mechanical seal when the flip top 130 is pressed down onto the upper surface 120 of the bottle cap 100.
  • the outer edges of the ridges 170, 180 may be slightly rounded or beveled, as shown in FIG. 1C, to facilitate their interlocking and separation when the flip top 130 is opened and closed.
  • the number of ridges 170, 180 may be varied. For example, in FIGS. 1A-1C, there are two ridges 170 provided on the seal 175 and two ridges 180 provided around the opening 160. Alternatively, either of the seal 175 or the opening 160 may be provided with a single ridge 170, 180. However, providing at least two ridges 170, 180 on each of the seal 175 and the opening 160 can provide a stronger seal of the opening 160 when the flip top 130 is pressed down in the closed position. Either of the seal 175 and/or the opening 160 may be provided with three or more such ridges 170, 180 to provide a stronger seal that is even more resistant to accidental opening of the flip top 130 due to internal pressure of the bottle contents.
  • the number of ridges 170, 180 provided on a particular bottle cap 100 may be selected based on several factors including, e.g., the desired pressure to be contained, the ease of opening the flip top 130 (more ridges 170, 180 may require a larger force to lift the flip top 130 from the closed position), the material(s) used to form the bottle cap 100 (stiffer plastics may require fewer ridges 170, 180 to obtain a strong closure of the flip top 130), the cost to provide more ridges, etc.
  • the seal 175 can be provided as a continuous wall configured to fit the opening 160, or as a solid protrusion that may provide additional mechanical stability and a stronger seal of the opening 160 when the flip top 130 is closed.
  • the bottle cap 100 can be formed from plastics used to make conventional bottle caps such as, e.g., PET (polyethylene terephthalate), HOPE (high-density polyethylene), LDPE (low-density polyethylene), or PP (polypropylene). Such materials are commonly used to form plastic bottles and caps. Other types of plastics and/or other materials can be used to form the bottle cap 100 or portions thereof.
  • the bottle cap 100 can be provided in a variety of sizes, depending on the size of the bottle opening and neck that the bottle cap 100 will be used with. For example, the most common size of a bottle cap used for many beverages is about 1-1/8 inches in diameter with the cap body 110 being about 1/2 inches high. This size cap is commonly used for a variety of beverage bottle sizes, including 12-oz, 16-oz, half-liter, liter, quart, 2-liter, and 3- liter bottles. Different sizes can be used to fit different sizes of bottle openings.
  • the opening 160 (and corresponding seal 175) can be provided in a teardrop shape, as shown in FIGS. 1 A-1C. Such shape facilitates easy poring of the bottle contents or drinking directly from the bottle when the flip top 130 is raised.
  • the opening 160 and seal 175 can be provided in a round shape. Such round shape may provide similar access to the bottle contents, but it will have a slightly larger area-to-perimeter ratio of the opening 160, and thus may be slightly inferior in resisting internal pressure of the bottle contents as compared to the teardrop shape, for a given configuration of the ridges 170, 180 and bottle cap material chosen.
  • the opening 160 and corresponding seal 175 can be provided in an oval or ovoid shape, which may increase the ability of the flip top 130 to remain closed at higher internal bottle pressures, but may also reduce the pour rate of liquids through the narrower opening 160.
  • the flip top 130 and the opening 160 can be sized to cover only a portion of the upper surface 120 of the bottle cap 100.
  • the length of the opening 160 and flip top 130 can be about 1/2 inches to about 3/4 inches long.
  • This relatively small size of the opening 160 and flip top 130 may be important for bottle caps 100 used to contain pressurized contents in a bottle, such as carbonated beverages.
  • the upward force on a closed flip top 130 is roughly proportional to the area of the opening 160 for a given internal bottle pressure
  • the closure or retaining force of the flip top 130 is roughly proportional to the total length of the ridges 170, 180 (e.g., to the perimeter length of the opening 160) for a given number and geometry of the ridges 170, 180.
  • the particular bottle cap embodiment illustrated in FIGS. 1 A-1C has been shown to be effective for providing a reliable seal against pressurized contents typical of carbonated beverages.
  • the area-to-perimeter ratio of a round opening 160 is equal to R/2, where R is the radius of the circular opening. (The area of a circular opening is 7tR 2 and its perimeter is 2KR, yielding a ratio of R/2.) Because this ratio is roughly proportional to the ratio of pressure forces on the flip top 130 to retaining or locking forces on the flip top 130, smaller values of this ratio are preferable to provide secure sealing of pressurized contents by the bottle cap 100. Accordingly, the exemplary bottle cap 100 shown in FIGS. 1 A-1C, sized for most common beverage bottles, has an opening 160 with an area-to-perimeter ratio that is less than about 3/16 inches.
  • the area-to-perimeter ratio of the opening 160 is preferably less than about this value of 3/16 inches for bottle caps 100 made from conventional plastic materials. A larger ratio would result in larger pressure forces on the flip top 130 relative to the closure forces provided by the ridges 170, 180 around the perimeter of the seal 175 and the opening 160, respectively.
  • a non-circular opening such as the exemplary teardrop-shaped opening 160 shown in FIG. 1 A will have a smaller area-to- perimeter ratio than a circular opening having the same area. Accordingly, such non-circular openings 160 can provide a smaller area-to-perimeter ratio for an opening having a particular area as compared to a circular opening having the same area.
  • the bottle cap 100 can be larger to accommodate larger bottle openings, but the area-to-perimeter ratio of the opening 160 should preferably remain less than a value of about 3/16 inches to ensure that the flip top 130 can reliably resist internal pressure to prevent accidental opening. In such embodiments, the flip top 130 would cover a smaller relative portion of the cap top 120 than the embodiment shown in FIG. 1 A.
  • larger bottle caps 100 can be provided with somewhat larger openings 160, e.g., openings 160 having an area-to-perimeter ratio of about 1/4 inches or even up to about 5/16 inches.
  • the reliability of the flip top closure can be increased for such larger openings 160, e.g., by providing a seal 175 that is solid or has thick walls and/or providing additional ridges 170, 180 around the perimeter of the seal 175 and the opening 160, respectively.
  • Bottle caps in accordance with the invention can be provided with various configurations for securing them to bottles.
  • a bottle cap 200 can be provided with internal screw threads 210.
  • Such threads 210 can be provided on the internal surface of the cap body 110. This configuration allows the bottle cap 200 to be easily screwed onto a conforming threaded bottle top, and is commonly used in plastic beverage containers.
  • the bottle cap 200 can include a breakable seal around the bottom perimeter of the bottle cap (not illustrated) that is seated below a ridge on the bottle neck when the bottle cap 200 is fully screwed down onto a threaded bottle top.
  • This type of seal is commonly used in plastic soda and water bottles, and provides a security seal that indicates the bottle cap 200 has never been removed if the seal is unbroken.
  • This exemplary configuration allows the cap 200 to be twisted on and off like a conventional screw-on cap, but also provides easier access to the bottle contents by simply opening the flip top 130.
  • the bottle cap 200 can be provided with a non-breakable ridge seal around the bottom perimeter of the bottle cap (not illustrated) that can also be seated below a ridge on the bottle neck when the bottle cap 200 is fully screwed down onto a threaded bottle top.
  • the non-breakable seal affixes the bottle cap 200 permanently to the bottle such that it cannot be unscrewed once it is installed. Therefore, the cap 200 cannot be twisted off, and access to the bottle contents is achieved only by opening the flip top 130.
  • FIG. 3 illustrates a bottle cap 300 similar to that shown in FIGS. 1 A-1C, where the bottle cap 300 has been provided with a locking clamp 310 around the lower perimeter.
  • This clamp 310 can be configured to slide over and interlock with a corresponding circumferential ridge 320 provided on the neck of a bottle 330.

  • Such attachment points can be formed using localized thermal fusion, plastic welding, adhesives, or the like. The attachment points can be formed such that they will break easily when the flip top 130 is lifted for the first time, thereby providing visible and tactile feedback confirming that the flip top 130 had not been opened previously.
  • any of the bottle caps 100, 200, 300, 400, 500 can be provided with a sealing film that can be broken upon first opening of such cap and provide visual evidence that the original bottle has remained sealed prior to such first opening.
  • a sealing film that can be broken upon first opening of such cap and provide visual evidence that the original bottle has remained sealed prior to such first opening.
  • Such tamper-resistant sealing films are common in the bottling industry, and can be made using thin films of foil, plastic, or the like that can be punctured or tom without requiring excessive force.
  • a sealing film can be provided over the top opening of a bottle, adhered to the upper rim, prior to installing a flip-top bottle cap. Upon opening the flip top 130 for the first time, the sealing film will be visible below the opening 160, 560, and can be easily punctured using a fingertip or other instrument. Alternatively, such a sealing film may be adhered to the lower portion of the opening 160, 560, rather than being adhered to the bottle top itself, and can be punctured in a similar manner.
  • a sealing film can be provided that extends across the opening 160, 560, and is adhered to the lower edges of both the opening 160, 560 and the seal 175.
  • the sealing film can be broken when the flip top 130 is lifted up for the first time, tearing the sealing film away from the bottom edges of the opening 160, 560. In this manner, a user can receive visible and tactile feedback that the contents of the bottle were safely sealed prior to first usage of the flip-top cap.
  • such sealing film may be provided only between the lower edges of both the opening 160, 560 and the seal 175, such that the sealing film has the shape of an open ring that does not span the entire width of the opening 160, 560. Such sealing film will also tear and provide tactile feedback upon the first lifting of the flip top 130
  • Attachment points between the flip top 130 and the cap surface 120 surrounding the opening 160, 560 can be provided together with any of the sealing film configurations described herein. Any other tamper-resistant packaging components and techniques known in the art may also be used with any of the bottle caps described herein.
  • a bottle cap can be provided having a cap body that is not round in shape but is shaped to conform to a non-circular opening of a bottle or container.
  • Such bottle caps can be configured to be secured to the bottle or container with a clamping arrangement, such as that shown in Fig. 3.
  • a non-circular cap can be configured to be adhered to the opening of a bottle or container, similar to the embodiment shown in Fig. 4.
  • These non- circular caps can include a similar opening, flip top, and various other features as described herein.

Abstract

L'invention concerne un capuchon de bouteille à partie supérieure rabattable qui permet un accès plus facile au contenu d'une bouteille par rapport à des capuchons classiques à ouverture par torsion. Le capuchon de bouteille peut être constitué de matières plastiques comprenant du PET, du PEHD, du PEBD, ou du polypropylène. Le capuchon comprend un trou à travers sa surface supérieure, et une partie supérieure rabattable qui se conforme à la forme du trou et peut être fixée au corps de capuchon par une charnière souple. Les périmètres de la partie supérieure rabattable et de l'ouverture sont pourvus d'une pluralité de crêtes qui se verrouillent afin de former un joint mécanique lorsque la partie supérieure rabattable est pressée vers le bas. Le rapport surface-périmètre de l'ouverture de capuchon peut être inférieur à environ 3/16 pouces, afin de fournir un joint qui résiste à la pression interne de boissons gazeuses. Le capuchon peut être apposé à une bouteille à l'aide de filetages, d'un collier de verrouillage, ou d'adhésifs. Des joints inviolables peuvent également être disposés sur le capuchon.
