The container having a valve body positionable in the opening of the container, the valve body having a plug member biased to allow fluid passage through the opening of the container when in a displaced position and to eliminate fluid passage through the opening of the container when the plug member is in a seated position. The keyed fluid dispenser assimilates a syringe and is releasably securable to the valve body for use in depressing the plug member by movement of a leaf spring when the keyed fluid dispenser is in position. The keyed fluid dispenser has indicia to provide for exact measurement and can be temporarily coupled to the container to provide ease of fluid transfer.

Description

    PRIORITY CLAIM
  • This invention is a continuation-in-part of U.S. patent application Ser. No. 13/008,121, filed Jan. 18, 2011 and entitled “Spring Loaded Fluid Safety Dispenser System” which 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 patents address proper dosing, a problem remains in that a child may access the medication or 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 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. 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 leaf 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. 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.
  • 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

  • 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 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. In a preferred embodiment, 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. When keyed alike, the flute 41 and tang cooperate allowing insertion of the receptacle insert for accessing the fluid held within the container 10. Alternatively, the receptacle insert 34 may be sized to create a seal, thereby acting as a keying feature. For instance, the receptacle insert may be 3.5 mm 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 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. Once secured, the keyed fluid dispenser and the bottle are in alignment forcing a proper seal necessary to allow the draw of fluid from the container. As the level of fluid in the bottle is lowered from consumption, it is more convenient to invert the bottle to allow fluid flow 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 body 11 permit venting of the container while secured together; venting is permitted by spacing the lower surface 60 and upper surface 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 FIG. 5. The displacement of the plug member permits fluid flow into the fluid dispenser. As shown in FIG. 6, 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.
  • Referring to FIG. 4, the keyed fluid dispenser 24 is illustrated as being disengaged from the container 10, the tang 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. FIG. 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. FIG. 6 depicts the keyed fluid dispenser 24 fully engaging the container 10. The tang 42 has passed through the aperture 31 and by rotating of the fluid dispenser 24, the tang is moved away from the flute that allowed movement through the aperture and is now used to temporarily secure the fluid dispenser to the bottle. Placing of the tang beneath the surface 58 assures proper sealing between the lower surface 60 of the fluid dispenser 24 and the upper surface 52 of the valve body 11. The plug member 64 is shown fully displaced wherein fluid can be drawn into the opening 73. 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 molded valve body 11 with the lid 13 attached by a living hinge 15. The upper surface 52 notched area provides the benefit of a drip collection, however, the notched area is not essential to the primary function of the fluid dispenser. Alternatively a lid may be sized to fit within the notched area 52.
  • Referring now to FIGS. 7-11, set forth is another embodiment of the invention having valve body 80 defined by a top surface 82, lower surface 84 and continuous side wall 86. The side wall 86 has a lower section 88 sized to frictionally fit within the mouth of a container and upper section 90 sized to overlap the upper edge of a container 10. In addition to the upper edge providing a fluid seal, the upper edge operates as stop measure to prevent the valve body from falling into the container.
  • The previous embodiment employs the use of a tang mounted on a fluid dispenser. As an alternative, set forth is an embodiment depicting the placement of a tang on the valve body with a receptacle flute placed on the fluid dispenser. Also unique to this embodiment is the use of a separate lid 92 for covering of the valve body 80 when it is not in use. The lid 92 is of conventional design having an internal thread groove, not shown, receptive to the outer screw thread 96 placed on the outer surface of the bottle. The keyed fluid dispenser 150 includes a plunger that is used to draw fluid from the container in a conventional manner by pulling on the handle 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 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 tang 152 and/or flute 154 placed in the top 80 can be keyed to a particular manufacturer or individual products. The tangs 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 lid 92 can be eliminated; however, for aesthetic purposes the lid allows the container to appear conventional and prevent debris from entering the aperture when stored. Should the lid be displaced, the bottle would remain sealed when the fluid dispenser is detached.
  • The valve body 80 has a centrally disposed aperture 100 for receipt of a keyed fluid dispenser. In this embodiment, the centrally disposed aperture 100 has tangs 102 positional along an upper area of the aperture 100 for use in aligning to flutes 104 of the fluid dispenser 150.
  • Referring to FIG. 8, the keyed fluid dispenser 150 is illustrated as being disengaged from a container 10, the tang 152 placed within the aperture 100, the size of which can be used to block most items from being inserted into the aperture. In this embodiment, the fluid dispenser 150 has a flute 154 formed into the receptacle insert 156. The flute 154 must align with the tang to allow insertion into the aperture. Illustrated is the leaf spring 170 pressing the plug member 177 against the lower opening of the aperture 100, providing a normally closed position. Shown in FIG. 8, the lid 92 is placed over the end of the bottle preventing entry of unwanted debris into the bottle. The valve body 80 available for receipt of the keyed fluid dispenser 150, the lid 92 has been removed, which engages the aperture 100 wherein tang 152 allows insertion by cooperating with the flute 154, the end 146 of the receptacle insert engages the upper portion 112 of plug member 177. The plug member 177 is displaced wherein fluid can be drawn into the opening 173. During this time, air is allowed to escape or enter the bottle so as to prevent a vacuum lock from occurring. FIG. 10 depicts the keyed fluid dispenser 150 fully engaging the container 10, the tang has been driven along the length of the flute and entered a flute offset by rotation of the fluid dispenser 150. The placement of the tang 152 into the flute 154 allows the movement through the aperture, and by engaging the offset, allows the fluid dispenser to be temporarily secured to the bottle. Placing of the tang within the flute offset further assures proper sealing between the lower surface 146 of the fluid dispenser 150 and the upper surface 82 of the valve body 80.
  • Referring now to FIGS. 12-19, set forth is a third embodiment of the instant invention depicting a valve assembly 200 valve body 210 with an upper surface 212 and centrally disposed aperture 214. Lid 216 is coupled to the top of the valve body 210 by a living hinge 218. The lid 216 includes a seal 220 and engages the aperture 214, securing the lid 216 to the valve body 210. An indentation 222 is provided beneath the lip 224 of the lid 216 for the ease of lifting.
  • FIG. 14 depicts a cross sectional view of the valve body 210 and lid 216. An inner surface of the valve body includes a thread groove 226 to provide an engaging thread to a bottle top. Upon entry through the aperture 214, an enlarge opening is defined by the inner sidewall of the bottle. A base holder 211 is formed along the upper edge of the side wall and may be formed for a continuous ledge placed around the inner circumference for holding of a plug member, or the ledge may consist of a non-continuous ledge.
  • FIG. 15 depicts the valve body 210 with a ratchet engagement 230 consisting of about thirty-two ratchets equally spaced around the circumference so as to allow unidirectional placement of the valve body 210 onto a bottle. In the preferred embodiment, the ratchet engagement 230 does not include a means for reversing the ratchet engagement so as to prevent removal of the valve body once installed.
  • The valve body 210 has a base 240 formed of a single piece of material, preferable plastic. The base 240 is a substantially round disk shaped member having a diameter defined by an outer edge wall 242 securable to a flange member 211. An inner edge wall 243 forms an open area 244 with at least one bridge support 246 extending from the inner edge 247 on one side of the inner edge wall to an inner edge 248 on the opposite side. A plug element 250 has a lower surface 260 constructed and arranged to engage the bridge support 246 and an upper surface 254 sized to plug the lower opening of the aperture 214. The bridge support 246 maintains the plug element in contact with the aperture to prevent fluid flow until a displacement of the plug element allows fluid flow. The base 242 and plug element 250 are preferably molded from a single piece of material and adjoined by a living hinge 252. The living hinge 252 is folded over to align the plug element 250 in an aligned position calculated to present the dome shape plug member into the lower opening of the aperture. Channels 254 are formed into the upper surface of the plug member 250 which facilitates fluid flow when the plug element is displaced by a receptacle insert 310. The channels allow ease of fluid flow even if the plug element is only partially displaced.
  • FIG. 18 depicts the valve body 240 with the plug element 250 in a folded position along living hinge 252 with the upper surface 260 of the plug 250 engaging the bridge support 246 which operates as a biasing spring. FIG. 19 depicts the valve body 210 mounted on a bottle 10 with base member 240 secured to the valve body by placement with flange member 211, the flange member surrounds at least a part of the base. The base member is snapped into the flanges with the dome shape portion of plug member 250 facing upward in a position that will seal the aperture 214 from fluid exiting the container. The fluid dispenser 300 has a receptacle insert 310 that fits within the aperture 214 and depresses plug member 250 away from the end of the aperture, eliminating the seal thus allowing fluid to be drawn into the fluid dispenser 300 by use of a syringe type mechanism as previously mentioned.
  • The embodiments disclose the use of a multi component fluid 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.
