Description

PRIORITY CLAIM

This invention is a continuation-in-part of U.S. patent application Ser. No. 12/981,040, filed Dec. 29, 2010 and entitled “Fluid Safety Dispenser System” claiming the priority date of Nov. 28, 2010 based upon Provisional Patent Application No. 61/407,775 entitled Fluid Safety Dispenser System, the contents of the applications are incorporated herein by reference.

FIELD OF THE INVENTION

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.

BACKGROUND OF THE INVENTION

The packaging for liquid medications used for children, adults, geriatrics and animals has always been vague and included a wide range of dosing. The problem is especially pronounced in pediatric elixirs wherein the dosing recommendations are by age, which can lead to improper dosing for children. Although there currently exists weight-specific dosage calculations presented on charts and pinwheels, they are not readily available to the general public. Even if available, the charts could present a confusing array of dosages that may not be understood by the general consumer. The Physician's Desk Reference may be used for the calculation, but such a reference book is not typically purchased or understood by the average consumer. It should be noted that even though an individual reaches maturity, dosing levels should still be of concern. Adults are of all sizes, and the elderly can be just as susceptible to overdosing as can a child.
While the instant invention is specifically applicable to liquid medications for children, adults, geriatrics and animals, it will be obvious to one skilled in the art that the disclosed system can be utilized with any liquid dispenser. However, for ease of explanation, this disclosure will exemplify pediatric elixirs as an example of use.
Applicant's U.S. Pat. Nos. 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. Should the guardian continue to give the child the same amount of medication months later, 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.
Thus, while the aforementioned addresses proper dosing, a problem remains in that a child may access the medication or fails the proper dosing amount is not properly measured. While known child resistant containers exist, they are only as secure as the closure top is installed properly. For instance, if the closure top is not properly engaged after opening, the safety aspect of the closure top is defeated and a child can easily access the medication. Further, once the cap is removed there is nothing to prevent the entire contents of the container from being poured out and ingested, e.g., by children who may not comprehend the threat of serious injury from improper use.
Even if the medication is in the hands of a guardian, the guardian may not have a measuring cup or understand liquid conversions. For instance, if a guardian is instructed to provide 20 ml 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.
Some 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.
The criticality of dosing is compounded by the readily available liquid medications which are marketed for treating, management or mitigation of most any ailment. For instance, novel pharmaceutical compositions such as Coricidin®, Coricidin D®, Comtrex®, Dristan®, Daycare®, Cotylenol®, Sinubid® and the like are now well known OTC products. These 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. When used properly, these medications are very predictable and beneficial. When 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). Or more critically, why a child's fever increased shortly after receiving a dose of acetaminophen (typically overdosing). Combinations of such compositions are commonly recommended under a physician's supervision; the combination only heightens the need for proper dosing. Well known measures are milliliters, ounces, teaspoons, tablespoons, capfuls, drops, cc's, all of which are simply poured or otherwise dispensed from the medicine container which compound the inaccuracies.
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 is 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 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. When normally assembled, the outer cap will freely rotate around the inner cap without moving the inner cap. When the slide is depressed by pressure exerted through the aperture against the action of the spring, the slide is moved to disengage the slot from the stop and partially out of the guideway.
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. 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.
While the prior art is directed to assuring that the consumer is knowledgeable of the proper amount of medication and the need for child resistant closures to the medication, no known prior art exists for keying a dosing container to a medication container. Thus, what is needed is a dosing syringe that is used to draw an exact amount of fluid needed to medicate an individual while assuring that only the proper dosing syringe will operate with the medication container.

SUMMARY OF THE INVENTION

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 an opening in the container for passageway of the fluids stored therein. A dispensing valve is positionable in the opening employing a spring loaded valve member capable of displacement between an open position to allow fluid passage and a closed position to eliminate fluid passage, and a keyed fluid dispenser 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 spring loaded valve member forming a flow through chamber when displaced by a keyed fluid dispenser, the dispensing valve forming a child resistant protector.
Another objective of the instant invention is to disclose the use of a keyed fluid dispenser that can be temporarily secured to a container having a matched dispensing valve.
Another objective of the instant invention is to disclose the use of a keying receptacle positioned on keyed fluid dispenser wherein the keyed fluid dispenser must be attached to a container before fluid can be drawn from the container, and the keyed fluid dispenser must be detached before the fluid from the keyed fluid dispenser can be released, wherein the fluid container is maintained in a closed position when the keyed fluid dispenser is detached.
Still another objective of the instant invention is to disclose the use of a geometrically keyed syringe dispenser and 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 measurement indicia for use in measuring the amount of fluid drawn from a container.
Another objective of the invention is to provide a container that is economical to manufacture and easy to use.
Other objectives and advantages of this invention will become apparent from the following description taken in conjunction with any accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Now referring to the Figures, set forth is a container defined by a bottom 12, a continuous sidewall 14, and an upper section 16. 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 liquid medicines for children. The upper section 16 of the container resembles a conventional bottle having a mouth 18 with threads 20 for receipt of a threaded cap 21. A valve assembly 22 is inserted into an opening of 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 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 grooves 41 which operate as a keying mechanism for receipt of matched protrusion 42 arranged on the receptacle insert 34. When keyed alike, the grooves 41 and protrusions 42 cooperate for temporarily accessing the fluid held within the container 10.
The aperture 31 and protrusions 42 are geometrically arranged to create a mating receptacle for use forming a dripless interface. Although simple protrusions are depicted, it will be recognized to those skilled in the art that the protrusions can be of any shape, size, position, or combination thereof so as to provide a keyed locking mechanism unique to a keyed fluid dispenser 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 top 56 of the valve assembly forms a cover over a valve body 50. The upper surface 52 of the valve body 50 has a notched area 54 for receipt of the protrusions 42, and is designed to allow the protrusions to rotate beneath the lower surface 58 of the top, temporarily securing the keyed fluid dispenser 24 to the valve assembly. Securing the keyed fluid dispenser to the valve assembly, and thus the bottle, insures proper alignment of the receptacle to the bottle by forcing a proper seal necessary during the draw of fluid from the container. As the level of fluid in the bottle is consumed, it may be more convenient to invert the bottle to draw fluid into the keyed fluid dispenser with the assistance of gravity. In such instances, 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. If large volumes of fluid are drawn, the lower surface 60 of the keyed fluid dispenser 24 and the upper surface 52 of the top 56 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 outer surface of the valve body 50 is circular in shape and employs an interior chamber 62 for receipt of displacement valve 64. The displacement valve 64 has a frusta-conical upper 66 to permit self-alignment into a circular 68 that adjoins notched area 54 and aperture 31. The displacement valve 64 includes a top sealing surface 70 that is juxtaposition against lower surface 72 of the valve body 50 creating a fluid seal for containing the fluids within the bottle until otherwise drawn. A spring 76 is positioned between a bottom surface 78 of valve body 64 and a spring ramp 80. The spring 76 maintains the valve body 64 in a sealed position when the keyed fluid dispenser 24 is removed from the aperture 31. It should be noted that the upper 66 on the valve body 64 is sized to open only when the keyed fluid dispenser 24 has been inserted far enough so that the receptacle end is depressed firmly against the upper 66 to create a fluid seal. In an embodiment that includes a notched area 54, the protrusions must be inserted into the notched area 54 for a proper seal to occur. The spring can be made of a higher tension to further inhibit children from accessing the fluids by requiring a higher fluid dispenser mounting pressure.
Referring to FIG. 3, the keyed fluid dispenser 24 is illustrated as being disengaged from the container 10, the protrusions 42 aligned for immediate insertion into grooves 41. The upper 66 of displacement valve 64 fits within the aperture 31, the frusta-conical shape of the upper 66 and top sealing surface 70 create a fluid seal. The spring 76 is biasing the displacement valve 64 against the valve body 50. FIG. 4 depicts the keyed fluid dispenser 24 partially engaging the aperture 31 of the container 10, the protrusions 42 are shown partially inserted into the length of the grooves 41, allowing the receptacle 34 to engage the upper 66 of displacement valve 64. The displacement valve 64 is also shown partially displaced wherein fluid can be drawn into the opening 73 which is fluidly connected with the upper chamber 75. During this time, air is allowed to escape or enter the bottle so as to prevent a vacuum lock from occurring. The upper 66 and top sealing surface 70 are shown separated, allowing fluid to be drawn into the keyed fluid dispenser by drawing of the plunger to create a vacuum. Fluid can then be drawn through the opening 73 into the upper chamber 75 for entry into the keyed fluid dispenser 24 through receptacle 34. FIG. 5 depicts the keyed fluid dispenser 24 fully engaging the container 10, the protrusions 42 have passed through the grooves 41 and are now inserted into the notched area 54 allowing the receptacle 34 to fully engage the upper 66 of displacement valve 64 creating a seal between mating surfaces. The displacement valve 64 is shown fully displaced wherein fluid can be drawn into the opening 73 which is fluidly connected with the upper chamber 75. The upper 66 and top surface 70 are now separated allowing fluid, including fluids having the thickness of syrup, to be drawn into the keyed fluid dispenser. Fluid can then be drawn through the opening 73 into the upper chamber 75 for entry into the keyed fluid dispenser 24 through receptacle 34. In this position, the spring 76 is fully compressed providing maximum sealing between the mating surfaces, namely the lower end of the receptacle and the upper end of the displacement valve. When a proper seal has been formed, the bottle can be inverted to allow fluid to be drawn into the fluid dispenser with the assistance of gravity.
The valve assembly shown in this first embodiment allows for the temporary securement of the fluid dispenser to the bottle. While complex components can be used to accomplish this task, a low cost method of manufacturing employs a top 56 formed from a disk shape member that is sized to cover the width of the container opening including the lip 71 of the container 10. The top 56 has a lower surface 58 that is attached to the upper surface 52 of the valve body 50. Attachment of the top 56 to the valve body is preferably by heat weldment, adhesive, or as illustrated in an alternative embodiment, by a single component. The valve body 50 includes a chamber or notched area 54 that, when the top 56 is secured to the valve body 50, forms an area that can be further keyed for receipt of the protrusions. For example, the notched area may be higher in one area so that a protrusion length must match in order to rotate. Another example can be the use of ramps wherein the protrusions assist in creating a pressure gradient for further sealing of the receptacle to the valve body.
The keyed fluid dispenser 24 includes a plunger 30 that is used to draw fluid from the container in a conventional manner by pulling on the handle 26 which creates a collection area for fluid beneath the plunger by the use of a vacuum void. The amount of fluid drawn can be checked against measuring indicia 48 which can be any type of indicia and is not limited to conventional measurements. For instance, the measuring indicia could refer to the third line, alphabet characters, shapes, colors, and so forth. The use of unique indicia further enhances the security of the fluid dispenser by informing the guardian that the fluid dispenser characters must match the medication instructions. Anything that provides a measurement level corresponding to the required dosing level is appropriate.
The protrusions 42 and/or grooves 41 placed in the top can be keyed to a particular manufacturer or individual products. The protrusions can be configured to prevent removal of the keyed fluid dispenser or simply keyed to allow proper displacement of the dispensing valve. It should be noted that the cap 21 can be eliminated; however, for aesthetic purposes the cap allows the container to appear conventional and prevent debris from entering the aperture when stored. Should the cap be displaced, the bottle would remain sealed when the fluid dispenser is detached.
The top 56 is also used to position the valve assembly at the top of the container, and is preferably oversized so that the valve assembly cannot be pushed inside the container. The disk covers the width of the container opening having a lower surface 58 that may be attached to the upper surface 52 of the valve body 50. Attachment of the top 56 to the valve body is preferably by heat weldment or adhesive. During installation, the valve assembly 22 is inserted into a container opening until the edge of the lower surface 58 of top 56 engages the lip 71 of the container top to assure proper positioning.
Referring in general to FIGS. 9-11, set forth is an alternative embodiment wherein the valve body 90 is defined from a single piece having a top 92, a bottom 94, outer wall 96 and inner chamber 98. The valve body 90 has a centrally disposed aperture 100 for receipt of the keyed fluid dispenser shown in the previous embodiment. The centrally disposed aperture 100 has a chamfered opening with sealing surface 104 forming the top of chamber 98. Displacement valve 110 has an upper section 112 with an outer surface containing grooves 114 for receipt of keyed alike protrusions placed on the keyed fluid dispenser. A sealing surface 116 is formed along the upper surface of the displacement valve 110 and is constructed and arranged to seal against the sealing surface 104 located at the top of the chamber 98. The grooves 114 are sized to engage the protrusions on the keyed fluid dispenser; failure to engage will cause an air gap that prevents fluid from being drawn from the container by the fluid dispenser or in a controlled manner. For instance, if the displacement valve is to be engaged, fluid could not be removed as no seal would be made to a keyed syringe. Thus, when the container is inverted, the fluid would likely fall to the floor. Further, if an inappropriate keyed fluid dispenser is used, without proper engagement of the grooves 100, the plunger could not draw fluid as no vacuum would be created.
The keyed fluid dispenser that is properly keyed is then matched with the grooves 114, wherein an internal spacing of the grooves is sized to allow fluid to be drawn from the container and into the keyed fluid dispenser. An upper section 112 of displacement valve 110 fits within the aperture 100 wherein the frusta-conical shape of the upper 112 and top surface 104 allow for a fluid seal. Similar to the previous embodiment, the spring 120 is used to bias the displacement valve 110 against the valve body 90 when in a closed position. The outer surface 96 of the valve body frictionally engages the inner surface of the bottle 10. FIG. 10 depicts the displacement valve 110 in a depressed mode wherein fluid can be drawn into the chamber 98 which is now fluidly connected with grooves 114. The upper 112 and top surface 104 are separated allowing fluid, including fluids having the thickness of syrup, to be drawn into the keyed fluid dispenser by drawing of the keyed fluid dispenser plunger which creates a vacuum. In this position, the spring 120 is fully compressed providing a tight seal between the mating surfaces, namely the end of the upper and the end of the keyed fluid dispenser receptacle. When a tight seal has been formed, the bottle can be inverted to allow fluid to be drawn with the assistance of gravity.
The two embodiments disclose the use of a multi component dispensing valve that, which will be obvious to one skilled in the art, can be made from various manufacturing techniques to lessen the amount of components used. The valve assembly and keyed fluid dispenser provide a lock and key type arrangement for the control of fluids from a container. The use of a keyed fluid dispenser verifies that the amount of fluid drawn is exact with the calibration provided by the manufacturer. For instance, if the fluid drawn is measured in ml, then the indicia on the measuring indicia will be marked appropriately. This provides further assurance that the keyed fluid dispenser can only be used in combination with the container to which fluid is to be drawn and the keyed fluid dispenser would have no other useful purpose. The use of all plastic materials allows the container and keyed fluid dispenser to be recycled.
