ASEPTIC PAC~AGE TAP
The preaent inven~ion relates to a qy~tem for the delivery of a solution from an aseptic pac~age and, in particular, to a tap for such a package containing solution~ ~or medical applications ~uch as enteral feeding, a~ by nasal gauge.
For the purpo~es of the pr~sent specification and claims, the term "ascptic packaging" iY intended to e~brace the packaging of various liquid~ within a carton, the carton being o~
the type that i9 punctured to obtain acces~ to the packaged liquid. When the packaqed liquid is a food product, ~uch as juicea or ~ilk product~, it i~
common practice to puncture the packaging at a pre~elected location (which i~ often weakened) and to withdraw the liquid through a straw. In Europe, it i9 known to provide a "tap" which i~ pointed to puncture a ~idewall of th~ packaging and which ha~ a 1uid paqsaqe allowing the contained liquid to be poured through the tap.
Th~ characteri3tic~ of the not~d aseptic packaging system~ render th~ir u~o de~lrable in many medical application~. For example, it ia often :desirabl~, or nece~3ary, to deliv~r liquid~ ~o a person by a nn~al tub~ for ~uch purpo~a a~ enteral feeding, tho d011v-ry of nUtri~n~J, tho delivory of ~edication, etc. Aseptic packaginq i~ oft~n ~uitabl~
for such llquld~. However, whll~ ~apt~c packaging has b~en e~ployed for certain ~dlcal ~o' UtionA, it has oft~n been th~ practlcu to op~n th~ p~ckaga~ and empty their cont~nt~ in~o ~ ~or~ tr~dltlonal - ;~
` i3~93 ~3 40390-48 container for delivery. ln part, this has resulted from limitations on package size. However, more recent packaging techniques allow the packaging of liquid in greater quantities. Also, the tap described above in the context of food products, has the drawback of not discharging the liquid in an even flow but, instead, discharges the contents of the package intermittedly as air enters the container through the tap.
A tap which addresses the intermittent flow characteristics of the food product taps described above is know and will be identified herein as the Rautsola tap, after its inventor. The Rautsola tap provides, inter alia, a fitting having a projectingtpenetrating tip to form an orifice through the carton/package sidewall.
A liquid passage through the fitting allows a dispensing of the packaged solution, while provision is made for make-up air to the interior of the package. The fitting is maintained and positioned in the package sidewall by threads which cooperate with the orifice through the package sidewall.
The Rautsola tap is dependent upon the cooperation of the threads of the tap with the packages sidewall and also requires a significant relative rotation between the package and fitting for securement and sealing.
French patent 8S7,465 to Herve refers to a tap for metallic packages, the walls of which have a relatively high rigidity. Thus, this tap has a resilient disc which is pressed into an opening in the metallic wall which has been previously provided with an aperture by means of a penetrating tip shown in Fig. 4. As can be seen from Figs. 5 to 7, this hole or aperture in the wall forms an inwardly extending ring flange which presses against the portion of said resilient disc which has been pressed into the package. In other words, this means khe ` _3_ 1319343 resilient material of disc does not expand within the passage but is compressed by said ring flange in order to secure and seal the known tap at the wall.
Such a type of tap is however not suitable ~or use with aseptic packages.
Moreover, as can be seen from Figs. 1 and 2 o~ the French patent, the resilient disc comprises a radial dimension which is much broader that the radial dimension of the stem portion ~eing joined with the penetrating tip. Th~reFore, said resilient disc cannot be introduced through the aperture in the wall without axially pressing cn it as, for example, by the screw o~ Figs. 5 to 7 of the French patent.
As with the Rautsola taps described above the present invention provides a system for the enteral delivery of a solution contained within an aseptic package without the intervening step of emptying the package into a traditional container. ln this manner, the solution may be dispensed through a giving set anc metering system of known design and, typically, via a tube as by nasal gauge. To this end, and in common with the Rautsola tap, there is provided a tap having a body, a package penetrating tip extending from the body, a liquid passageway extending from the tip and through the body for dispensing liquid from the package and a fluid passageway extending from the tip through the body for admitting make-up air to the package. The package wall is al~o engaged to secure the tap within the package wall. However, the tap of the present invention employs a cylindrical member of a resilient material positioned ~between the body and the penetrating tip, the cylindrical member being insertable through the package wall in trailing relation to the tip. The resilient cylindrical member is selectively compressed, along its cylindrical axis, causing it to expand within the package against the 13193~3 package wall. ln this manner, the package wall is engaged without the requirement of a thread-type cooperation between the tap and package wall and without a significant relative rotation between the tap and package. ln a preferred embodiment of the present invention, a rotation of approximately 90 (one quarter turn) of a portion of the tap of the present invention is required for full engagement of the package wall.
ln the disclosed embodiment, the present invention employs a circular platform, the platform having cams extending from its surface toward the package penetrating tip of the tap. A cap having a -- --` 5 ~ ~19~3 platen de~ining an endwall thereof is positioned with the platen generally parallel to the platform and with a ~idewall o the cap ~urrounding a portion of the body. A resilient, cylindrical member is positioned between the cap and pentrating tip for selective compression along its cylindrical axis (and expan~ion within the package against the package wall) on movement of the cap away from the platform.
The platform of the di closed preferred embodiment i9 provided with a plurality of cams while the platen carrie~ multiple cam followers, each cooperating with a diferent one of th~ platform cams. On rotation of one or both of the platform and cap relative to the other, the cam~ and cam followers 3electively establi~h the di~tance between the cap platen and platorm and, accordingly, the state of compres~ion of the resilient member. That i~, the relative angular or rotational orientation of tho platen and platform establishes the distance between the platen and platform and the stata of compression o the cylindrical, re~ilient member. The cam followers may be formed a~ ramps with each ramp being provided with a plateau to provida a stable, compressed state of the cylindrical, r~silient member.
Briefly summarized, in contrast to the prior art arrangements, with the present invention, securement of the tap of the present invention to a package is accomplished by compression of the cylindrical resilient member within the package, said member being in its generally cylindrical configuration during entry Only after the cylindrical member has been introduced into the package is it compressed along its cylindrical axis to expand within the package and engage the side ~31~343 wall of the package to seal the orlfice formecl by tip and also to secure the tap to the package.

Figure 1 is an exploded view ancl partial cut-away illustrating a preferred embodiment of the present invention.
Figure 2 is a view of the embodiment of Fiyure 1 as seen along the line 2-2 of Figure 1.
Figure 3 illustrates a portion of the embodiment of Figure 1 viewed along the arrow 3 in Figure 1.
Figure 4 shows the cooperation of a tap in accordance with Figures 1-3 with the wall of a package and is illustrated as viewed in the direction of the arrow 3 in Figure 1.
Figure 1 is an explodecl view of a -tap in accordance with the present invention, including a body designated generally at 10, a cap desic~nated generally at 11, a cylindrical r resilient member 1~ and a penetrating tip member designated generally at 13. The body 10 is secured to a reservoir 14 in any clesired manner, the reservoir being connected to an elongaterl -tubing 15 which extends to a "giving set" and any desired metering system. The reservoir 14 may be ~ecured to the body 10 as by gluing it to a collar thereof. Accumulation of solution clispensed from an aseptic package will occur within the reservoir 14, allowing a monitoring of the dispensing.
The penetrating -tip 13 includes a generally conical portion 16 and an extending stem 17, the conical portion 16 and stem 17 being joined to each other at a shoulder 18. The conical portion 16 is obliquely truncated at a surface 19, the surface 19, in cooperation with the conical portion 16, providing a cutting edge to facilitate penetration of an ~r 131~3~3 aseptic package. A ~luid pa~ageway for nake-up air i~ repr~s~n~ed by dashed line 21 and extenda fro~ the surface 19 through the tip 13 to e~it through tho ~idewall of the stem 17. A ~econd paaaagaway for solution to be di~p~n~ed i~ represented by a da~hed line 22 and e~tend~ fro~ an opsnlng 23 in th0 conical portion 16 of tip 13 and through the ~tem portion 17. Passageways 21 and 22 cooperate wlth pas~agawdys within the body portion lO in a matter to be descri~ed more fully below.
A generally cylindrical, resilient member 12 i9 configured to fit over the stem portion 17 of tip 13 to abut against the shoulder 18. On insertion of the tip 13 through the wall of a package, the orifice made by the tip 13 will allow the member 12 to extend through the package wall and into the interior of the pac~age. ~g will be apparent from the discussion below, the cylindrical, resilient member 12 will be compressed along itq cylindrical a~is such that it will expand within the packaging to engage the package wall and seal the orifice in that wall formed by the tip 13 as well as aecure the tap to the package. The solution within the package will be dispen~ed ~hrough the pas0ageway 22, entering the tip 13 at the opening 23, while make-up air to the interior o~ the package will enter the package via the passageway 21.
The body lO is provided with a platform 25, the platform 25 having a central hub 26 and extending cam me~ber~ 27. The hub 26 ha~ a cantral opening 28 (See Figur~ 2) for accepting the stem 17 of tip 13.
Tha stem 17 may be secured within the opening 28 of hub 26 in any deslred manner, a~ by gluing, for example. A fir~ pas~geway 29 extende rom th~
opening 28 through the b~dy lO and into the res0rvoir 14 vla a ~tub 30. The pa~ageway 29 i~ repre~ented by a dashed lin~ in ~igure 1. A 3econd fluid 131~3~
pas~ageway 31 e~tend~ through a stub 32 in a ~id~wall of the body 10 and i~ also represented by a dashed lin~.
Tho pas~agoway 31 will, on proper orientation of stem 17 wlthln body 10, e0tablish fluid communlc~tion with the p~ageway 21 of tlp 13 when the stem 17 of the tip 1~ is within the opening 28 of hub 26. Similarily, fluid communication between the pas~ageway 29 of body 10 and the pa~ageway 22 of tip 13 is e~tablished when the ~tem 17 i9 inserted within the opening 28 and hub 26 of body 10. Thus, a passageway ~or solution i~
established through the opening 23, pa~sageway 22 and pas~ageway 29 and into the re3ervoir 14 for a solution to be di~pensed while make-up air for the package interior i9 provided through ~he pa3qageway 31 of body 10 and paqiageway 21 o~ tip 13.
As described to this point, assembly of the tip 13 and body 10, with their respective pa~sageways 21/31 and 22/29 in communication, establi~hes a tap by which solution within an aseptic package may be dispensed, with a provision for make-up air.
However, the tap, as described to this point, i8 not securable to a package.
Securement of the tap to a package i9 accomplished by compression of the cylindrical resi~i~nt member 12 within the pacXage. As noted above, the member 12 i9 po~itioned over the stem 17 and enters th~ package by an orifice formed by the tip 13. Uuring entry, tho member 12 i~ in its generally cylindrical confiquration. ThiR
configur~tion i~ illustrated in ~igure 3 which may be ter~od the packaga penetrating configuration. After entry into the package, tho memb~r 12 i9 compre~ed along ito cylindrical axiA ~o e~pand within ths pack~ge and ~ngag~ th~ 3id~wall o th~ package to s~al the orifice ~orm~d by th~ tip 13 and aleo to 9- ~3193~
secur~ the tap to the packag~. Thi~ conflguration of the member 12 i~ illu~trated in Flgure 4 with the cut-away element 35 representlng the packaqo wall.
Compression of the member 12 is accomp1ished by a ca~ming cooperation between the cams 26 on the plat~or~ 25 and cam surfaces 36 within a cap 38. The cap 38 includes an endwall 39, the inner ~urface o~
which serve~ as a platen carrying the camming ~urfaces 36. In a preferred embodiment, the platform 25 i~ generally circular, while the side~all of the cap 38 is cylindrical and extends over the body 10 with the platen surface o~ endwall 38 being generally parallel to the platform 25. The ca~ ~urfaces 36 each cooperate with a different one of the cams 27 and are formed as ramp~ ~uch that the relative rotation or orientation of the cap 38 and body member 10 e~tablishes the di~tance between the platen surface of endwall 39 and the platform 25. That i~, rotation of the cap 38, for e~ample, relative to the platform 25 cause~ the cams 27 to ride up the platformR of camming ~urfaces 36 and urge the cap away from the platform 25 and into compressing relation with the member 12. Compres~ion of the member 12 along it~ cylindrical a~is ~ill re~ult in an anlargement of that memb~r in a radial dir~ction, cau~ing it tc engage a wall 35 wi~hin a package it has penetrat~d--~ee Figura 4. In this mann~r, the tap i~ secured to the package wall whlle the orifice through that wall is sealed.
Obvlou~ly, many modifications and variations of the pre~ent invention are po~ible in light of the above teachings. For c~ampl~, th~ sidewall of the cap 38 ~acllitate~ manipulation o~ that cap during relative rotational movem~nt with the body 10, and it~ platform 25. To facilitato th~t movemQnt, whilc maintainin~ comp~ctneso in the t~p, it ~y desirable to provide the ~idewall with a cutout to acco~odate - lo - ~31~3~
the stub 32. Thi~ cutout is illustrated at 40 in Figures 3 and 4. Al~o, to control the inlet for mak~-up air, it may be desirable to provide a cap for the stub 32. Such a cap is illu3trated at 41 in Figure 1. The cap 41 will also a~sist in manipulation of the body 10 during e~tablishment of its relative angular orientation with the cap 38.
The cap 41 is not illustrated in Figures 2-4.
Further, to reduce friction between the wall 35 and a penetrated package (during rotation of the cap 38, for example), it may be desirable to provide a reduced surface engagement area on the cap 38 such a~
that illustrated at 42. The surface 42 may be provided with a recess to accept the end of the member 12, as desired. Finally, to provide a compres~ed state of member 12 having enhanced stab.ility, the camming surfaces 36 may be provided with plateaus in the regions indicated at 44, the plateaus being either ramps of reduced angle or "flat" portions. It i9 therefore to be understood that, within the scope of the appended claims, the invention may be practiced otherwi~e than i9 specifically described.

Similarily, fluid communication between the pas~ageway 29 of body 10 and the pa~ageway 22 of tip 13 is e~tablished when the ~tem 17 i9 inserted within the opening 28 and hub 26 of body 10. Thus, a passageway ~or solution i~
established through the opening 23, pa~sageway 22 and pas~ageway 29 and into the re3ervoir 14 for a solution to be di~pensed while make-up air for the package interior i9 provided through ~he pa3qageway 31 of body 10 and paqiageway 21 o~ tip 13.
As described to this point, assembly of the tip 13 and body 10, with their respective pa~sageways 21/31 and 22/29 in communication, establi~hes a tap by which solution within an aseptic package may be dispensed, with a provision for make-up air.
However, the tap, as described to this point, i8 not securable to a package.
Securement of the tap to a package i9 accomplished by compression of the cylindrical resi~i~nt member 12 within the pacXage. As noted above, the member 12 i9 po~itioned over the stem 17 and enters th~ package by an orifice formed by the tip 13. Uuring entry, tho member 12 i~ in its generally cylindrical confiquration. ThiR
configur~tion i~ illustrated in ~igure 3 which may be ter~od the packaga penetrating configuration. After entry into the package, tho memb~r 12 i9 compre~ed along ito cylindrical axiA ~o e~pand within ths pack~ge and ~ngag~ th~ 3id~wall o th~ package to s~al the orifice ~orm~d by th~ tip 13 and aleo to 9- ~3193~
secur~ the tap to the packag~. Thi~ conflguration of the member 12 i~ illu~trated in Flgure 4 with the cut-away element 35 representlng the packaqo wall.
Compression of the member 12 is accomp1ished by a ca~ming cooperation between the cams 26 on the plat~or~ 25 and cam surfaces 36 within a cap 38. The cap 38 includes an endwall 39, the inner ~urface o~
which serve~ as a platen carrying the camming ~urfaces 36. In a preferred embodiment, the platform 25 i~ generally circular, while the side~all of the cap 38 is cylindrical and extends over the body 10 with the platen surface o~ endwall 38 being generally parallel to the platform 25. The ca~ ~urfaces 36 each cooperate with a different one of the cams 27 and are formed as ramp~ ~uch that the relative rotation or orientation of the cap 38 and body member 10 e~tablishes the di~tance between the platen surface of endwall 39 and the platform 25. That i~, rotation of the cap 38, for e~ample, relative to the platform 25 cause~ the cams 27 to ride up the platformR of camming ~urfaces 36 and urge the cap away from the platform 25 and into compressing relation with the member 12. Compres~ion of the member 12 along it~ cylindrical a~is ~ill re~ult in an anlargement of that memb~r in a radial dir~ction, cau~ing it tc engage a wall 35 wi~hin a package it has penetrat~d--~ee Figura 4. In this mann~r, the tap i~ secured to the package wall whlle the orifice through that wall is sealed.
Obvlou~ly, many modifications and variations of the pre~ent invention are po~ible in light of the above teachings. For c~ampl~, th~ sidewall of the cap 38 ~acllitate~ manipulation o~ that cap during relative rotational movem~nt with the body 10, and it~ platform 25. To facilitato th~t movemQnt, whilc maintainin~ comp~ctneso in the t~p, it ~y desirable to provide the ~idewall with a cutout to acco~odate - lo - ~31~3~
the stub 32. Thi~ cutout is illustrated at 40 in Figures 3 and 4. Al~o, to control the inlet for mak~-up air, it may be desirable to provide a cap for the stub 32. Such a cap is illu3trated at 41 in Figure 1. The cap 41 will also a~sist in manipulation of the body 10 during e~tablishment of its relative angular orientation with the cap 38.
The cap 41 is not illustrated in Figures 2-4.
Further, to reduce friction between the wall 35 and a penetrated package (during rotation of the cap 38, for example), it may be desirable to provide a reduced surface engagement area on the cap 38 such a~
that illustrated at 42. The surface 42 may be provided with a recess to accept the end of the member 12, as desired. Finally, to provide a compres~ed state of member 12 having enhanced stab.ility, the camming surfaces 36 may be provided with plateaus in the regions indicated at 44, the plateaus being either ramps of reduced angle or "flat" portions. It i9 therefore to be understood that, within the scope of the appended claims, the invention may be practiced otherwi~e than i9 specifically described.
