Description
- This is a continuation-in-part of U.S. application Ser. No. 08/501,815 filed on Jul. 13, 1995.
- This invention relates to an improved specimen container which is adapted to maintain the sterile integrity of the container and to prevent leakage yet which can be temporarily, partially opened and closed with one hand, leaving the other hand free to insert the specimen with a needle and syringe (N&S), cannula and syringe (C&S) or a syringe with no attachment without having to first put the instrument down.
- Specimen containers are well known in the art and are available in a host of shapes and sizes. However, a user of specimen containers typically must use both hands to operate the container. The user must hold the receptacle in one hand and remove the cover with the other hand, while holding a syringe containing an aspirated specimen. The user must then squirt the specimen into the open receptacle, risking the possibility of splash back or spillage. Therefore, it has been identified that a specimen container which enables a user to grasp, open and close the lid with one hand, and with the user's other hand, to inject the aspirated specimen into the container without splash back or to withdraw a specimen from the container without spillage, would be beneficial to the user. Further, it is also recognized that a specimen container which facilitates insertion of a cannula or a syringe with no attachment into the specimen container by providing a cannula guide would also be beneficial.
- It is therefore a primary object of this invention to provide a specimen container which enables a user to grasp a specimen container with one hand and, with the user's other hand, to inject the aspirated specimen into the container without splash back or to withdraw a specimen from the container without spillage.
- It is a further object of this invention to provide a specimen container having a plug cover which enables a user to grasp, open and close the plug cover with one hand, and with the user's other hand, to inject the aspirated specimen into the container without splash back or to withdraw a specimen from the container without spillage.
- It is a further object of this invention to provide a specimen container which facilitates insertion of an instrument, such as a needle or cannula, into the specimen container by providing a guide for the tip of the instrument.
- It is a further object of this invention to provide a lid, provided with one or more self-resealing portals therethrough, for any type of receptacle adapted to contain a solid and/or a liquid.
- A preferred embodiment of the specimen container of this invention, adapted to maintain the sterile integrity of the container and to prevent leakage, comprises: a receptacle having an opening; a lid comprising a means to seal said opening and having a top surface and a bottom surface and a bore therethrough; and a plug comprising, an upper and lower shoulder, at least one of said shoulders is deformable, wherein said plug is seated in said bore of said lid so that said upper shoulder is seated on said top surface of said lid and said lower shoulder is seated on said bottom surface of said lid, and a membrane capable of being penetrated with a material transfer device and which self-reseals to prevent leakage from said container. Material transfer device generally refers to a variety of instruments used to transfer fluids or other similar materials from one point to another, including but not limited to cannulas, needles and syringes connected to a somewhat pointed attachment adapted to puncture a membrane.
- The specimen container may further comprise a plug cover, preferably comprising high density polyethylene, which covers a top surface of the plug and which is adapted to be raised and lowered by a person's one hand leaving the person's other hand free to insert a specimen into, or withdraw a specimen from, the specimen container. The plug cover is preferably hingedly fixed to the lid and includes a flange which surrounds the upper shoulder of the plug when in a lowered position. The plug cover may further comprise a flange which is adapted to engage a corresponding flange on the lid when the plug cover is in a lowered position so that the plug cover is removably fixed in the lowered position to further prevent any material from entering or leaking out of the receptacle. A portion of the plug cover preferably extends beyond the outer edge or boundary of the lid. The plug may be adapted to be removed after the plug is inserted through and seated in the bore for purposes of replacement or otherwise.
- The shoulders of the preferred embodiment of the specimen container are generally annular and the plug of the specimen container may further comprise an instrument guide for directing the instrument into the plug and through the self-sealing membrane. If such an instrument guide is provided, the guide typically has an outer diameter and the plug should further comprise one or more means for altering the outer diameter of the instrument guide to enable the guide to adaptably flex in order to accommodate instruments such as needles or cannulas having varying outer diameters. The means for altering the outer diameter preferably comprises one or more expandable slits in the plug which extend radially outward from the instrument guide.
- In the specimen container of the invention, the upper shoulder preferably has an outer diameter greater than the lower shoulder and the lid may further comprise a conduit, which extends into the receptacle of the container downward from the bottom surface of the lid, through which said bore further extends, and which comprises a lower lip on which the lower shoulder of said plug is seated.
- The receptacle typically comprises threads proximate the opening of the receptacle and the means to seal the opening of the receptacle comprises threads on the lid which correspond to threads on the receptacle. The plug of the specimen container may be molded from thermoplastic rubber and may also include a continuous ridge on the top surface of the plug, wherein the ridge presses against an underside of the plug cover to provide additional protection against leakage.
- Yet another preferred embodiment of the plug and plug cover of the invention are connected to each other by a flexible cord. The plug, plug cover and flexible cord of this embodiment are preferably a molded unitary member molded from thermoplastic rubber, C-Flex or isoprene.
- Yet another preferred embodiment of the improved specimen container of the invention, adapted to enable a user to inject or withdraw materials into or out of said container using a material transfer device with minimal risk of spills or leaks, comprises: a receptacle having an opening; a lid comprising a means to seal said opening and at least a first bore and a second bore therethrough; and a first plug, which is seated in said first bore of said lid comprising, a membrane capable of being penetrated with a material transfer device and which self-reseals to prevent leakage from said receptacle; and a second plug which is seated in said second bore. Said second bore is adapted allow a material transfer device, a syringe without an attachment, a sterile loop and transfer pipet to be inserted at least partially into the specimen container. Both the first and second plug may each be provided with a plug cover. The plug covers may be connected to their respective plugs with or without flexible cords.
- Yet another preferred embodiment of the improved specimen container of the invention, adapted to enable a user to inject or withdraw materials into or out of said container using a material transfer device with minimal risk of spills or leaks, comprises: a receptacle having an opening; and a molded lid comprising a bore therethrough and a self-resealable membrane insert-molded into the lid and across the bore.
- Yet another preferred embodiment of the improved specimen container, adapted to enable a user to inject or withdraw materials into or out of said container using a material transfer device with minimal risk of spills or leaks, comprises: a receptacle having an opening; and a molded lid, having a top surface, comprising a bore therethrough and a self-resealable membrane fixed to the top surface of the lid and across the bore.
- The lid of the invention may be adapted for virtually any type of receptacle for containing a solid or liquid adapted to be covered or otherwise sealed with a lid having one or more limited access portals therethrough. It is envisioned that the lid of the invention may be useful for non-medical uses including but not limited to collecting environmental or industrial specimens for testing, storing and transportation.

- A preferred embodiment of the container of this invention is shown and generally referred to in
FIG. 1 ascontainer 10.Container 10 generally comprisesreceptacle 12 andlid 14.Threads 26 are provided onreceptacle 12 proximate the lip ofreceptacle 12 which engage corresponding threads 27 (shown inFIG. 2B ) located on the inside ofcylindrical wall 23 oflid 14 to positively seallid 14 from being axially displaced fromreceptacle 12.Lid 14 is provided withvertical ridges 24 around the outside ofcylindrical wall 23, to griplid 14 while attaching and removinglid 14 to and fromreceptacle 12, respectively, and sleeve-like bore 25 which extends (shown inFIGS. 2A and 2B ) downward throughlid 14 and is located off center oflid 14. - As an alternate to
threads receptacle 12,lid 14 andreceptacle 12 may alternatively be provided with a means for snapping the lid onto the receptacle. -
Container 10 is also provided with plug 38 (shown in FIGS. 2B and 4A-4F) which is seated inbore 25 and has a top shoulder and a bottom shoulder which sit on the top surface oflid 14 and the bottom edge of sleeve-like bore 25, respectively. The top ofplug 38 is covered by plug cover 16 (shown inFIGS. 1, 2A , 2B and 3A-31).Plug cover 16 is preferably made of molded high density polyethylene. -
Plug cover 16 is provided withcam 20 which removably fixes the cover tolid 14 by hingedly engaging two raised cam locks 18 provided on the top surface oflid 14.Cam 20 snaps into and is frictionally held in cam locks 18. Each one of cam locks 18 (FIG. 2C ) has a generally triangular shape from the side, however the top of the triangle is missing to formchannel 17. The center of the triangle is also missing to formgroove 19.Channel 17 andgroove 19 of one of the cam locks should be parallel to channel 17 andgroove 19 of the other cam lock.Plug cover 16 is removably fixed tolid 14 by pressingcam 20 intochannel 17 untilcam 20 locks into place ingroove 19.Channel 17 should angle inward slightly down to groove 19 so that the lower end ofchannel 17 which opens intogroove 19 is smaller in width than the largest diameter ofgroove 19. The diameter ofcam 20 should be slightly greater than the lower end ofchannel 17 and the same as or slightly smaller than the diameter ofgroove 19. -
Plug cover 16 is also provided with notch 36 (shown inFIGS. 3G and 3H ) onflange 34 which engages a corresponding notch located onflange 22 provided onlid 14.Tip portion 28 ofplug cover 16 extends partially outward from the periphery oflid 14 to enable the user with one hand to release and raise plug cover 16 from the notch onflange 22 with a flip of the user's thumb or finger.Tip portion 28 should extend beyond the periphery oflid 14 as needed to provide the user sufficient leverage to raiseplug cover 16. The periphery oflid 14 may have an inwardly stepped edge (FIG. 10 ). InFIG. 10 ,lid 110 is provided with steppededge 112 so that the user can wedge his or her finger betweensteps 112 andtip portion 116 ofplug cover 114. Utilizing a stepped edge reduces the distance to whichtip portion 116 needs to extend beyond the outer periphery oflid 110. -
Plug cover 16 is portioned into three increasingly stepped sections as shown inFIGS. 3E and 3G . The first and lowest section ofplug cover 16 is bounded bycam 20 at one end and rises in elevation to the second and middle section at step 30 (FIG. 3A ).Wall 21 extends downward from the bottom surface of plug cover 16 (FIGS. 2B, 3B , 3C, 3D, 3E, 3G and 31) so that when plug cover 16 engages the notch onflange 22 in a closed position,wall 21 substantially covers and seals the top ofplug 38 and bore 25. The middle section of the plug cover rises further in elevation to the third and upper section at step 32 (FIG. 3A ). The upper section formstip portion 28 which extends beyond the periphery oflid 14.Wall 21 should have an inside dimension which is the same as or slightly greater than the corresponding outer dimension ofplug 38. In the preferred embodiment, the outer dimension of the upper shoulder ofplug 38 is 0.577 inches (FIG. 4C ) and the inside dimension ofwall 21 is 0.580 inches (FIG. 3E ). -
Plug cover 16 is also provided with notch 36 (FIGS. 3G and 3H ) proximate the lower edge offlange 34.Flange 34 is essentially a thickened and slightly forwardly protruding portion ofwall 21 nearest tip portion 28 (FIG. 3F ). When plug cover 16 is in a closed position, notch 36 ofplug cover 16 engages the notch onflange 22 oflid 14.Notch 36 can be readily released from the notch onflange 22 by lifting gently upward ontip portion 28. Depending on the relative dimensions of the specimen container, notch 36 and the notch onflange 22, when engaged should be small enough to require only minimal pressure to disengagenotch 36 from the notch onflange 22. For example, notch 36 oflid 14 is a mere 0.005 inches thick. The notch onflange 22, likewise, corresponds in size to notch 36. -
Flange 22 is not limited to a single notch or a single flange as shown inFIG. 2A but rather may comprise a series of notches or flanges which extend further around the circumference oflid 14. For example, it may be desirable to provide a greater notch area onflange 22 to hold plug cover 16 more securely againstlid 14 when plug cover 16 is in a closed position. This object may be achieved by increasing the size offlange 22, and likewise the notch onflange 22, or by providing more than oneflange 22 around the perimeter oflid 14, each flange having a notch capable of engaging a corresponding notch onplug cover 16. - As noted,
container 10 is also provided withplug 38.Plug 38 is preferably made of molded thermoplastic rubber, C-Flex or isoprene.Plug 38 is preferably deformable so that the plug can be inserted intobore 25 for quick and easy assembly.Plug 38 has a largerupper shoulder 40 and a smallerlower shoulder 42, (FIGS. 4A-4C and 4E). Whenplug 38 is inserted intobore 25,shoulder 40 is seated on the top surface oflid 14 andshoulder 42 is seated on the bottom edge ofbore 25, as shown inFIG. 2B .Shoulder 42 preferably has alip 43 which slightly wraps around the bottom edge ofbore 25 to preventplug 38 from being pulled up throughbore 25 as the end of a cannula is pulled out through plug 38 (FIGS. 2B and 4E ).Plug 38 has a slightlyelongate portion 50 betweenshoulders like bore 25 as shown inFIG. 2B .Elongate portion 50 ofplug 38 should be about the same as the internal length ofbore 25. -
Plug 38 also has acentral bore 44, however bore 44 does not extend the entire length ofplug 38 as shown inFIG. 4E . A thin section at the upper end ofelongate portion 50 is solid across its diameter to form self-sealingmembrane 51. A smallinverted notch 47 is provided in the bottom ofmembrane 51 to guide a material transfer device (not shown) back out throughplug 38 and to channel any material back into receptacle 12 (FIG. 4F ). The hole created by inserting a transfer device throughmembrane 51 will effectively close when the transfer device is removed due to the elasticity of thermoplastic rubber, C-Flex or isoprene. The term material transfer device generally refers to any of a variety of instruments having a pointed tip capable of puncturing a membrane and used to transfer fluids or other similar materials from one place to another, including but not limited to cannulas, needles and syringes connected to an attachment having a pointed tip adapted to puncture a membrane. -
Upper surface 41 ofplug 38 is substantially solid across its face except fortransfer device guide 46 and expansion slits 52. Annular sealingridge 48 also extends upward fromupper surface 41 so that when plug cover 16 is closed, sealingridge 48 presses firmly against the bottom surface of the middle portion of plug cover 16 withincylindrical wall 21 to further inhibit leakage fromcontainer 10.Top surface 41 may also include radial ridges 53 (FIG. 4D ) to aid the user to line up the tip of the transfer device with the central bore. - The plug of the invention may also be made by a technique known as insert molding. This technique requires shooting heated plug material into a pre-molded housing in the lid. Insert molding would eliminate the need for separate production and installation of the plug.
Transfer device guide 46 is a cylindrical well formed inupper surface 41.Membrane 51 forms the bottomtransfer device guide 46.Transfer device guide 46 should have a diameter sufficient to receive at least the tip of the transfer device. The preferred embodiment oftransfer device guide 46 has a diameter of {fraction (3/32)} of an inch. Expansion slits 52 are small slits formed inupper surface 41 which radiate out fromtransfer device guide 41. There are four expansion slits in the preferred embodiment. The expansion slits are designed to expand slightly when a transfer device is inserted into and removed fromcannula guide 41 to avoid undue friction between the transfer device and the transfer device guide and to prevent the transfer device guide from splitting. Similar tomembrane 51, slits 52 should return substantially to their original position once the transfer device is removed, due to the elasticity of thermoplastic rubber, C-Flex or isoprene. - Another preferred embodiment of the specimen container of the invention, generally referred to as
container 100, is shown inFIGS. 5 and 6 .Container 100 comprisesreceptacle 102,lid 104 and plug 106. Unlikebore 25 described above as off center oflid 14, bore 110 and plug 106 are centered inlid 104.Plug 106 is substantially similar to plug 38 ofcontainer 10 except thatplug 106 is substantially solid across its top surface. As shown inFIGS. 5 and 9 , plug 106 could be provided withannular ridge 108 having an inner diameter which corresponds approximately to the inner diameter ofbore 110 to facilitate insertion of a transfer device into and throughbore 110. - Another preferred embodiment of the specimen container is shown in
FIG. 7 and 8, generally referred to ascontainer 122. Similar tocontainer 100,container 122 comprises areceptacle 122,lid 124, bore 128 and plug 126, however bore 128 and plug 126 are off center oflid 124. - Another preferred embodiment of the plug and plug cover of the specimen container of the invention are shown in
