Definitions

  • This invention relates generally to fluid safety dispensers and, in particular, to a child resistant container having a dispensing valve that is operated by an independent keyed fluid dispenser.
  • Applicant's U.S. Patent 6,276,533 and 6,581,773 recognized the need for a weight based dosing regimen for pediatric elixirs, and disclosed a container mounted apparatus to accomplish the proper dosing; the contents of the patents are incorporated herein by reference.
  • These disclosures address the dosing recommendations on containers that are based on the child's age; unfortunately the significant variations of weights of children of the same age makes dosage determination based on age not only inaccurate but most dangerous. For instance, when a child's physician instructs a child's guardian to deliver a certain amount of elixir to a child on a certain date.
  • the dosage may not be correct if the child's weight has changed.
  • a child's weight can change quickly, and if the guardian does not inform the physician of the weight change, the dosage will be improper.
  • Continual adjustments in dosing, necessitated by the child' s rapidly changing body weight, are important to ensure maximum therapeutic response to a medication.
  • the guardian may not have a measuring cup or understand liquid conversions. For instance, if a guardian is instructed to provide 20ml of medication but has misplaced or was not provided with a measuring cup, the guardian may assume 1 ounce (over dosing) or 1 tablespoon (under dosing) is acceptable. Similarly, a guardian only conversant in the English system may receive instructions in ml and attempt to estimate the equivalent in teaspoons. Another example would be if a guardian is instructed to provide two teaspoons but employs a tablespoon. It is not uncommon for someone to believe one tablespoon equals two teaspoons (under dosing) . Further, the use of a teaspoon or tablespoon used for eating is not accurate as there is no required standard in the industry. Conventional eating spoons are shaped for aesthetic appearance, not for medical dosing.
  • Medication containers rely upon the use of the container cap as a measuring cup; again the medication is estimated as it is not possible to end with full caps unless the dosing is rounded upward or downward.
  • Medication containers may include a measurement container; however, they can be displaced or intermixed with other measuring containers, again risking improper dosing.
  • formulations generally contain aspirin, ibuprofen, salicylamide or acetaminophen, one or more conventional antihistaminics , decongestants, cough suppressants, antitussives and expectorants, and are designed to address cough, cold, cold/like and/or flu symptoms, discomfort, pain, headache, fever or any number of aliments and the general malaise associated therewith.
  • these medications are very predictable and beneficial.
  • improper dosing occurs, it is not uncommon to hear a guardian inquire as to why their child's fever has not gone down despite the use of medication prescribed (typically underdosing).
  • U.S. Pat. No. 3, 240,373 discloses a container with a side type dispenser wherein a release lock tab prevents opening of the slide unless first released.
  • U.S. Pat. No. 3,160,301 discloses a container which uses a key and slot wherein the key is attached to an outer cap with a resilient, flexible strap.
  • U.S. Pat. No. 3,501,041 discloses a bottle cap having an inner cap member enclosed by a sleeve member, and connecting means carried by the members provides for relative rotational and axial movement there between. Engagement of a separable locking means with the cap and sleeve members locks the members against relative rotational movement and thus permits threaded engagement or disengagement of the cap from the bottle.
  • U.S. Pat. No. 3,684,115 discloses a safety container having a skirt with internal screw threads to form a conventional screw cap closure, and an overcap completely covering the threaded closure member and being freely rotatable in relationship thereto.
  • the overcap has on its top a projecting stud and a similar shaped opening which serves as a key for unscrewing the inner closure member of another closure of similar construction.
  • U.S. Pat. No. 3,698,585 discloses an inner cap member adapted for being threaded onto the neck of a bottle for closing the opening therein.
  • An outer cap member interlocks with the inner cap member when it is turned in a direction to apply the inner cap member to the bottle. When turned in the opposite direction, the outer cap member normally does not interlock with the inner cap member.
  • U.S. Pat. No. 3,869,058 discloses a safety closure for a container to prevent inadvertent opening of the container.
  • the closure includes an inner cap having an internal threaded portion to be attached to the threads on the neck of the container and an outer cap overlying the inner cap.
  • the top of the inner cap has a raised plate or ledge which is tapered and is provided with notches extending inwardly of the outer rim and a leaf spring centrally located on the top of the inner cap.
  • the underside of the top of the outer cap has tracks to form a guideway and a stop.
  • a slide is disposed on the guideway between the inner and outer cap and engages the stop to prevent lateral movement of the slide.
  • U.S. Pat. No. 4,281,771 discloses a child-resistant cap closure with incorporated means for over-ride of conventional normally disengaged torque couplings which includes a hole formed in the top surface of the outer cap, a formed plug having a locking protuberance and removal ring, and a plurality of spaced stop lugs formed annularly on the top surface of the inner cap.
  • the free and separate movement of the outer cap is prevented in either direction of rotation by the plug's insertion into the hole of the outer cap as to place the base of the plug in the space between the stop lugs of the inner cap, rendering the cap non-child-resistant at the time of consumer purchase.
  • U.S. Pat. No. 4,854,459 discloses a container having a cylindrical neck at the top and threads molded about the exterior of the neck, as well as an inner cap and outer cap.
  • the inner cap has a top and cylindrical side wall with threads molded on the inside of the side wall so as to mate with the threads of the container.
  • the top or side of the inner cap has ratchet type segments on its outside and the outer cap has ratchet type segments on the inside of its top or side.
  • the outer cap has a cylindrical side wall and is usually freely rotatable about the inner cap so as to be childproof. When in the childproof configuration as described, downward pressure is required by the user so as to engage the two ratchet type segments and thereby engage . the two caps to permit opening.
  • U.S. Pat. No. 5,115,928 discloses a child-resistant closure and shell.
  • the shell mounts a latching key and the closure provides a complementary latch.
  • An alignment structure provides for aligning the latch and key for movement of the latching key from a mode in which the key is inactive to a mode in which it engages the latch to inactivate the child-resistant function of the closure. In that position the shell and closure are movable in both clockwise and counter-clockwise directions.
  • Leaf spring fingers may be provided to elevate the shell relative to the closure to provide an additional child-resistant function.
  • the latching key may be hingedly or slideably secured to the shell.
  • U.S. Pat. No. 5,484,070 discloses a container having a syringe tip connector for coupling to a container, the device directed to aspirating medication into a syringe for oral administration to children, adults or animals.
  • U.S. Pat. No. 7,111,746 discloses a child resistant closure having a pair of nested inner and outer caps.
  • the inner cap is coaxially positioned and nested within the outer cap such that a row of angular abutments on the inner cap engage a row of angular abutments on the outer cap when engaged to allow rotation of the cap.
  • the present invention provides a container and keyed fluid dispenser to inhibit inadvertent access to unmeasured quantities of potentially dangerous products, such as medicines, by requiring the user to repeat one or more deliberate steps before fluid can be extracted from the container .
  • the fluid safety dispenser system of the instant invention includes a container for storage of fluids having a controllable opening in the container for passage of fluids stored therein.
  • a dispensing valve is positionable in the opening, employing a leaf spring biasing a plug member wherein an open position allows fluid passage and a closed position prevents fluid passage.
  • a keyed fluid dispenser is releasably securable to the dispensing valve for use in drawing fluid from the container.
  • An objective of the instant invention is to disclose a dispensing valve having a leaf spring biased plug member forming a controllable flow through chamber; the plug member can be displaced by a keyed fluid dispenser forming a child resistant protector.
  • Another objective of the instant invention is to disclose the use of a keyed fluid dispenser in combination with a leaf spring biased plug member wherein the fluid dispenser can be temporarily secured to the container to permit inverted fluid withdrawal.
  • Still another objective of the instant invention is to disclose the use of a geometrically keyed syringe type dispenser and matched fluid container.
  • Yet another objective of the instant invention is to eliminate the need for a sealing cap. Yet still another objective of the instant invention is to disclose the use of a keyed syringe dispenser having personalized measurement indicia for use in measuring the amount of fluid drawn from a container.

  • the container may contain most any fluid, but for purposes of illustration, the container detailed in this specification will be a bottle used for storing liguid medicines for children.
  • the upper section 16 of the container resembles a conventional bottle having a mouth 18 with threads for receipt of a threaded cap.
  • a valve assembly 22 is threaded onto the mouth of the container for use in combination with a keyed fluid dispenser 24 allowing controlled retrieval of the fluids stored within the container.
  • the keyed fluid dispenser 24 of the instant invention is defined by a handle 26 having a shaft 28 coupling the handle to a plunger 30 that is used for drawing fluid into the chamber 32 by pulling a vacuum in the dispenser.
  • the end of the keyed fluid dispenser includes a receptacle insert 34 specifically designed to engage the valve assembly 22. But for the receptacle insert, the keyed fluid dispenser assimilates a conventional syringe type device.
  • the dispenser valve assembly 22 has an aperture 31 for receipt of the receptacle insert 34.
  • the aperture includes at least one flute 41 which operates as a keying mechanism for receipt of " matched tang 42 arranged on the receptacle insert 34.
  • the flute 41 and tang 42 cooperate allowing insertion of the receptacle insert for accessing the fluid held within the container 10.
  • the receptacle insert 34 may be sized to create a seal, thereby acting as a keying feature.
  • the receptacle insert may be 3.5mm in diameter, thereby requiring an aperture of the same size less a space to allow for a close tolerance coupling. If the aperture is too small, then the receptacle insert will not fit. If the aperture is too large, then the receptacle insert can be inserted but will not be able to draw fluids by vacuum. If the container is inverted with an undersized receptacle insert, fluid will spill around the fluid dispenser.
  • the keying feature may include both a tang/flute and unique diameter sizing.
  • the dispenser valve assembly includes a body 11 having a threaded inner surface and a lid 13 attached by a living hinge 15.
  • the lid 13 need not be threaded as the valve assembly prevents removal of the fluid contents unless the fluid dispenser is engaged. Rather, the lid prevents debris from collecting around the aperture and is sized to slip on and off an upper portion of the body 11.
  • the flutes 41 and/or tangs 42 are geometrically arranged to create a mating receptacle and dripless interface. Although simple tangs are depicted, it will be recognized to those skilled in the art that the tangs can be of any shape, size, position, or combination thereof so as to provide a locking mechanism unique to a keyed fluid dispenser having a mating receptacle for either a particular manufacturer, line of products, or type of product.
  • the keyed fluid dispenser 24 permits a child' s guardian to insure that the medication to be dosed to a child can be performed without displacing all medication held in a cabinet or refrigerator. If all medication containers are keyed, only the proper keyed fluid dispensers need be provided, thereby assuring that only the particular medication is utilized. This has particular benefit for medication that must be refrigerated, as it is difficult to hide medication in an unlocked refrigerator, and expensive to have a locked refrigerator for medicine only. Further, most medicine cabinets are unlocked and become a facilitator for selecting the wrong medicine.
  • the keyed fluid dispenser is not affected by temperature and can be left on a counter to provide a visual reminder of medication due. The keyed fluid dispenser would have no other use and preferably be discarded or recycled after use.
  • the body 11 of the valve assembly 22 is further defined by an outer surface 50 and an inner surface 53.
  • the inner surface includes a thread channel to cooperate with the thread formed along the outer surface of the bottle top.
  • the upper surface 52 of the valve body 11 has a notched area to collect fluid spillage, if any, when the receptacle insert 34 is removed from the aperture 31.
  • the aperture 31 includes a flute 41 for receipt of the tang 42.
  • the flute and tang are constructed and arranged to allow the tang to be directionally focused through the aperture and rotate beneath the lower surface 58 of the body 11 when fully inserted. Engagement of the lower surface with the tang temporarily secures the keyed fluid dispenser 24 to the valve assembly.
  • the keyed fluid dispenser and the bottle are in alignment forcing a proper seal necessary to allow the draw of fluid from the container.
  • a proper seal during the transfer necessitates that the alignment between the bottle and the keyed fluid dispenser is maintained while the bottle is inverted.
  • the lower surface 60 of the keyed fluid dispenser 24 and the upper surface 52 of the body 11 permit venting of the container while secured together; venting is permitted by spacing the lower surface 60 and upper surface 52 in an amount sufficient to allow air to be drawn in when fluid is removed, yet insufficient to allow fluid to escape.
  • the lower surface 58 includes a plug member 64 that is biased into the lower opening of the aperture 31. While a round plug is depicted, the plug can be of any size or shape; and the function of which is to seal the aperture from fluid flow until the plug is moved from the aperture.
  • the plug 64 is biased into the lower end of the aperture by a leaf spring member 76.
  • the leaf spring member 76 and plug 64 can be attached to the body 11 or, more preferably, made of resilient material with a distal end of the leaf spring member positioned along the top edge of the bottle before the valve assembly is inserted into the bottle opening, effectively capturing the end of the leaf spring between the bottle surface and the body surface.
  • the plug member 64 is shaped to permit self- alignment into the lower end of the receptacle and of a material that further assists in sealing while maintaining integrity of the fluid stored within the bottle. For instance, if the aperture does not include a flute, the plug member 64 may consist of a hard plastic ball shaped member. If the receptacle includes a flute within the aperture, the plug may include an elastomeric coating or be formed of a softer material that allows conforming to a non-circular opening. The plug member 64 is displaced from the aperture 31 by the end 61 of the receptacle insert 34 when inserted as shown in Figure 5. The displacement of the plug member permits fluid flow into the fluid dispenser.
  • the fluid dispenser 24 can be rotated upon insertion wherein tang 42 is positioned beneath the surface 58 allowing for the aforementioned temporary securement of the fluid dispenser to the container.
  • the leaf spring can be made of a higher tension to further inhibit children from accessing the fluids by requiring higher fluid dispenser mounting pressure in order to overcome the leaf spring biasing pressure.
  • the keyed fluid dispenser 24 is illustrated as being disengaged from the container 10, the tang 42 aligned for immediate insertion into flute 41.
  • the upper portion 67 of plug member 64 fits within the aperture 31.
  • the leaf spring 76 is pressing the plug member 64 against the aperture 31 opening in the normally closed position.
  • Figure 5 depicts the keyed fluid dispenser 24 engaging the aperture 31 of the container 10, the tang 42 shown inserted into the aperture allowing the receptacle 34 to engage the upper portion 67 of plug member 64.
  • the plug member 64 is also shown displaced wherein fluid can be drawn into the opening 73. During the fluid draw, air is allowed to enter the bottle so as to prevent a vacuum lock from occurring.

Abstract

La présente invention concerne un système distributeur de sécurité de fluide ayant un récipient de stockage de fluide monté à clavette sur un distributeur de fluide. Le récipient ayant un corps de clapet pouvant être positionné dans l'ouverture du récipient, le corps de clapet ayant un composant de bouchon dévié pour permettre le passage de fluide à travers l'ouverture du récipient lorsqu'il est dans une position déplacée et pour éliminer le passage de fluide à travers l'ouverture du récipient lorsque le composant de bouchon est dans une position installée. Le distributeur de fluide monté à clavette reçoit une seringue et peut être fixé de façon amovible au corps de clapet pour utilisation dans la dépression du composant de bouchon par déplacement d'un ressort à lame lorsque le distributeur de fluide monté à clavette est en position. Le distributeur de fluide monté à clavette a des repères pour permettre une mesure exacte et peut être temporairement couplé au récipient pour permettre un transfert aisé de fluide.
