Description

i3~

This invention relates to child resistant packages.

Background and Summary of the Invention It has been recognized that packages for medicinal and other materials should preferably be resistant to removal by childern. In the most commonly utiliz2d types of child re~i~tant package~, the package includes a closure which require~ a simultaneous application of axial pressure and rotation o the closure relative to the contalnerO Such simultaneous movements have been very effective in providing a child resistant feature. Howe~er, they have been difficult to u~e by the elderly or disabled who find it di~icult to make such .simultaneous manipulationsO Accordingly, it has ~een common for pharmacists to provide to the elderly or disabled an additional snap-on cap that can be used in lieu o~ the child resi~tant c losureO
~ k has al~o been heret~fore sugges ted that a closure be provided ~hat can be used in one positiQn as a child resis~ant clo~ure and then turned over and used in a conventional manner on the container as applying by the closure by threadingO
The pre5ent invention is directed to providing a child resistant package which does not rPquire simultaneous push or axial and rotating ~orces, which utilizes the simple expedient of moving a part axially to unlock the closure a~ter which it can be removed by a mere axial movement in the opposite direction; and which in the unlocked position can be ut.iliz~d to reclose the conta.iner without activating ;3~

the child resistant feature thereby providing an additional mode of use~
In accordance with the invention, the child resistant package comprises a container and c~osureD The container has a side wall, a bottom wall and an open end. The closure in-cludes an outer ~ember having a por~ion thereof ex~ending through an openi.ng in the outer member ~uch that axial pr~3-sure may be applied through this portion to move the inner rnember relative to the outer member in an axial directionO A
liner in~ert ~ealingly engages the upper en~ o~ the conkainerO
The inner member and the liner have interengaging portions .such that when the closure is removed from the container, the lin~r in~ert i~ al~o removedO A portion of the liner defines a ~pring between the liner and the i~ner member to yieldingly urging the inner member axially outwardly toward the outer memhern The container ha~ radially resilient portions on the upper end o~ the ~id~ wall, and the outer member .includes a peripheral ~kirt having a rib adapted to engage the radial re~ilient portions on the container~ ~he inner member 'na~ an annular w~ll adjacent the ~Xirt of the outer inember~ The annular wall has a bead thereon operable upon axial movement of the i~ner member towar~ the container t~ ~nove the radially movable portions of the container and disengage them from the rib o the outer member~ The wall of the inner member and and the ~irk of said outer member having interengaging portions which engage upon axially outward movement of the inner member relative to the outer member so that the closure can be removed by axial movement carrying with it the outer member, the inner member and the insert.

Referring to FIGSo 1 and 2, the child resi tant package embodying the invention comprises a container 10 and a closure 11~
The ~ontainer is made o plastic, comprises a side wall 12, a bottom wall 13, the side walL being cylindrical and having an open upper endO The container 10 is urther provided along its side wall 13 with a plurality of circum-ferentially qpaced axially extending portions 14 at the upper end that are supported in cantilever fashion so tha~ they can ~le~ radially inwardlyO The portions 14 defining locking lugs, a,~ pres~ntly de~cribedO
The closure 11 includes an outer member or lock ring 15 and an inner or release member 16 as well as a liner insert 17. The outer member li has a top wall 18 with a cylindrical op~n.inc~ 19 and a peripheral s~irt 200 The inner member 16 includ~s a cylindrical portion ~1 including a ~op wall 22 and a ,side wall 23 that extends upwardly into the opening 19 in the outer member 150 In the locked position the top wall 22 of portion 21 is flush with the top wall lg of the outer member lS~ The cylindrical portion 21 defines a release button for unlocking the closure, as presently descxibed~ The inner memhe.r 16 further includes an annular horizontal portion 24 ex-tending radially outwardly from side wall 23 and an annular wall 25 that ~xtends along the inner sur~ace of the skirt 20 o~ the outer member 15.

5i3~

The inner insert 17 includes a central flat portion 26~ a plug pox~ion 27 that forms an inner seal with the inner surface of ~he wall 12 at the upper end and also func~ions as a spxing, and a peripheral ~lange 28 that overlies the upper 5 end and extends downwardly for a short distance about the periphery o~ the up~er end of the containex~
As furthar sh~wn in FIGo 2~ the inner surface of the skirt 20 ~f the outer member 15 i~ formed wi~h an annular bead 30 that engages beneath a shoulder 31 on each of the radial portions 14 to loc~ the closure on ~he container. In the pos.ition shown in FI~. 2, the outer surface of the lower end o~ the inner me~ber 16 i9 formed with an annular bead 32 that enyage~ an annular groove 33 spaced above the bead 30 in the inner surface of the skirt 20.
~5 The outer rne~ber 15 and inner member 11 are preferably made Oæ rigid plastic material such as high density polyethylene or polypropyleneO The inner in~ert 17 is preferably made o~
~l~xible plastic such as low density polyethylene~ The ~on-tainer is preferab~y made of rigid transparent or translucent plastic such as polypropylene, high density polyethylene or polystyrene.
Referring to FIG. 3, when it is desired to remove the closuxe, an ax.ial force is applied to the release button 21 moving the inner member 16 axially inwardly relative to the ou~er member 15 against the ~pring force of the portion 27 of the insert 17. This causes the lower end of the annular wall 25 of the inner member 16 to engage do~wardly and outwardly tapex~d surfaces 35 on the upper end of the ~ 3~

radial por~ion~ 14 camming them inwardly in~o grooves 36 in the side wall l2, thereby disengaging the radial portions 14 from the annular bead 30 of outer member 150 Thi~ also moves the annular wall 25 downwardly bringing the bead 32 into engage-ment with another annular groove 34 on the inner surface ofskirt 20 positioned between the groove 33 and at ~he juncture o skirt 20 and bead 30~ The closure is then ~ree to be re-m~ved by merely grasping the periphery which may be formed with serrations 37~ As the closure is lifted9 an annular rib 38 on ~he inner surface of the wall 25 engages the periphery o~ the insert 17 to remove it with the remainder of the closure.
With the clo5ure in locked position, a protective flange 39 on the container serves as a deterrent to prying the closure offO
When it is desired to re-apply the closure, a mere axial movement i~ provided on the outer member and force in an axial direction causes the outer memher 15 to move axially relative inwar.dly to the inner member 16 to relock the closure~
By leaving the release button depressed as shown in FI~. 4, the closure be~omes a non~child resistant closure and can be applied by simply holding the release button in the ,~epressed position and pushing the closure onto the containerO
In this position, the locking lugs or portions 14 are not engaged by the bead 30, the bead 32 on the inner member 16 remains in engagement with groove 34 and the insert is not ~lexed on the containersO
To change to a child resistant mode, it is only necessary to push the outer me~ber or locking ring axially i3~

further until it snaps down under the locking lug on the radial por~ions.
It can thus be seen that there has been provided a child resistant package that requires only axial motion to open the pa~kage, that will function in a child resistant mode or a non~child resistant mode~ The closure has an outer Inember and an inner me~ber permitting these members to have di~ferent colors~
