Filed Apr. 1, 1959, Ser. No. 803,467 v Claims. c1. 215-7 This invention relates to closures for sealing containers, such as bottles, and more particularlyto a type of closure intended to prevent tampering with the-contents of the container, since the closure cannot be removed from the container without leaving an indication thereof, such as printed words Has Been Open-Ed.then visible through the transparent top of the cap.

The closure shown and described herein includes a cap member adapted to be threaded upon the neck of the bottle having the usual screw threaded top finish, and gasket means within the cap for contacting the top of the neck which also constitutes a locking member and through which force is applied to compress it against .the end of the neck and effect atight seal when the cap is rotated to screw it in place.

The cap and locking member are formed with oooperating parts, which cause the cap and member to move.

Referring to the drawings there is of closure embodying the invention adapted to be applied to the neck 10 of a bottle which is provided with a conventional thread 11. The closure comprises a cap member 12 internally threaded at 13 for engagement with the bottle thread 11. It has a fiat crown 15 from the under surface of which depend a plurality of projections arranged in a circular series, including diametrically opposite ratchet teeth 16 having a vertical front wall 18 which leads as the closure is rotated to screw it on the bottle neck, and an inclined surface 19 which is formed to extend upwardly and rearwardly from the leading end of the teeth 16, and is curved in cross section.

Also included in the circular series are projections 20 likewise arranged diametrically opposite each other, and being positioned respectively immediately back of each one of the teeth 16. They are rectangular and formed with a front vertical wall 21 and a rear vertical wall 22. In'the' closure shown in the drawings the cap 12 has a pair of teeth 16 and a pair of rectangular projections 20, and is rotated clockwise, as viewed from the top, to thread it upon the bottle neck. p The cap is preferably made of plasticmaterial', such as transparent polyethylene the purpose of whichwill presently be explained.

" A combined inner locking member and gasket 30itis positioned in" the cap member between the crown 1-5 and a ledge 31- formed around the inner surfaceof the threaded skirt of the cap. Member, 30 may be madeof flexible material, preferably of polyethylene, and is formed with a relatively thin peripheralgflange 32 the overall diameter of which is; greater than the inside diameter of the ledge 31, and much greater'than the inner dialme being elastic will yield and allowmember 30 to' snap into place. The-construction is such as to render removalof member 30 extremely difiicult without destruction oftlie associated parts. I

Member 30 is. also .molded with a pluralityof projections extending upwardly therefrom and arranged in a circular series. They are adapted to cooperate with the projections of cap member 12, and comprise a pair of diametrically opposite ratchet teeth 35 having'a rear wall 56 which trails as the closure'is rotated to screwit on the bottleneck, and an'inclined surface 37 which extends downwardly and forwardly from the trailing end. Surface 37 of teeth'35 is normally in contact with the inclined surface 19 of teeth 16, as shown in Fig. Included'in the circular series of member 30 are "other projections 40 also arranged diametrically'opposite each other, and being positioned respectively immediatelyforward of teeth 35. They are rectangular in section, as

. shown in, Figs.v 6 and 7, and are formed with a front wall 41 and a rear wall 42, the latter being normally in contact with the front Wall 1801? the teeth 16.

For thepurpose of easy assembly in vertical alignment, the circular series of projections of member 30 areformed within an annular groove 50 in the top surface of the member, and within which groove the circular series of projections of the cap 12 extend, see Figs. 3,

its top surface has been opened the latter word being shown one form 7 Thus, when member; 30 p is e case may be, will be hidden beneath suitable embossing,

indicated at 55, and which may be molded on the under surface of the crown is of cap 12. Each embossed area is large enough for this purpose, the spaces 56 between remaining naturally transparent, and also being sufficient in area to serve as windows throughwh'ich the lettering or other suitable indici'a willbe plainly'visible when the respective series of projections of the cap and member are in the relative positions shown i Figs. '7 and 2.

Member '30 has {an annularbe'ad 57 formed on its upper surface between the lettering and the 'fia'nge 32. The

head has a'rounded top surface contacting the flat under lsrn'faee of the crown 15. When the cap is screwed down tightly force is applied to the head 57 which causes'the has lower surface of member 30 to be compressed against the bottle top and effect a tight seal. Because ofthe line contact of the parts, best shown in Fig. 3, frictional force's therebetwcen will be minimized.

The operation of the closure is as follows. Assuming the cap 12 and member 3e are in the relative position shown in Figs. 1, 3, 4, '5 and 6, with the cap tightly applied to the bottle neck 10, upon counter-rotation of cap 12 member 30 will remain stationary because of its much greater contacting areapressing against the top of "the bottle neck, and the relatively small area engaging along theline contact of head 57. Since the contacting surfaces 19 and 37 are relatively short and also are rounded in cross section with a short and long radius respectively, they likewise engage along a line and any friction generated between them will be negligible.

Therefore, ratchet teeth 16 will ride up ratchet teeth 33 pressing downwardly on member 30 so that its adhe- "sion to the bottle top will be' maintained, member 30 yielding somewhat until the teeth move far enough .relatively to jump each other, and reach the position shown in Fig. 7. When this occurs the vertical walls 22 and 41 of projections and 40 will be brought into confronting relationship as well as the vertical walls 18 and 36 of ratchet teeth 16 and 35, thus locking these two parts of fthe closure against further relative movement in either direction.

The closure will now be loosened on the bottle top ,andmay be easily unscrewed along the bottle threads, "the printedwords on member '30 being now in afixed position under the windows 56, asshown in Fig. 2, indicating that the closure has been opened. It may be applied again to reseal the bottle but without changing the .position of the lettered indication.

If desirable, a separate gasket or liner could be in- V cluded in the assembly shown in Fig. 3 having a suitable plastic-coated paper face, such' as saran, adapted to resist slippage-on the end of a glass container. In this instance the under surface of the locking member would be formed with an annular row of ratchet teeth such as shown in Patent'No. 2,560,793, issued to me July 17, 1951, and

"for the same purpose.

'I'claim: p I

1. A closure for sealing the opening through the end of a containen having an outer cap member for rotary application to the end of the container, and a resilient "lockin'ginember within the cap, the locking member and the cap having surfaces, substantially aligned with the "end sealing surface of the container, and being formed t'o "engage with a line contact, and said members having "of said-ratchet teeth which, upon .rotation of the cap engage positively to cause the locking member to rotate with the 'cap to force the locking member towards the end of the container and apply pressure thereto, said ratchet teeth having normally opposed surfaces inclined in such direction and at such an angle that, upon counterrotation of the cap said inclined surfaces slide relative to one another urging the locking member away from the cap to cause said ratchet teeth to jump each other with their vertical faces opposed, and ,said cooperating parts having other vertical surfaces normally spaced apart in a rotary direction adapted to engage following the jumping of the'ratchet teeth, and ,so that the cap and the locking member will thereby be prevented from moving relatively in either direction of rotation for the pur pose set forth.

2. A closure for sealing the opening through the end of a container, having an outer cap member for rotary application to the end of the container, and a resilient locking member within the cap constituting 'a gasket engageable with said container end to close the opening and being capable of resisting slippage thereon when under pressure, the locking member having its upper face formed with a convex bead adjacent its outer edge adapted'to contact the fiat under surface of 'the crown of the cap, the locking member and the cap having cooperatin'g parts which include ratchet teeth having vertical faces, and said parts having other vertical surfaces normally in opposed relation to the vertical faces of said teeth which, upon rotation of the cap engage positively to cause the locking member to rotate with the cap to force the locking member against the end of the container teeth, and so that the cap and the locking member will thereby be prevented from moving relatively in either "direction of rotation for the purpose set forth.

,3. The structure according to claim 1 in which the J side wall of the cap isformed with an internal ledge adjacent its crown, and the locking member has a relative'ly thinflexible flange around its outer edge greater in diameter than the inside diameter of said ledge.

4. The structure accordingjto claim 1 in which-the upper surface of the locking member is relatively close to the inside top surface of the cap and is marked'with indicia, and the crown of the cap has at least one transparent zone and one non-transparent zone, both being inrotary alignment with each other and with said'indicia, the latter being normally hidden beneath said non-transparent'zone, and said zones being so spaced and positioned that, following the initial relative movement of the flocking member and cap, the said .indicia will be exposed'to view beneath the transparent zone of the cap to thereby indicate that the closure has been unscrewed to open the container.

5. A closure for sealing the opening througdthecnd of a container, comprising *an' outer cap member for rotary applicationto theend-of the container, and a lock- :ing member-within the cap adapted to "close'said opening,

saidmembers having cooperating parts adapted to cause said members to move in unison during theapplication of the closure to'the container, and upon counter-rotation of said closure to cause said members to move'relative to one another a predetermined distance into locked rela .tionship with respectto rotary movement relatively "in either direction for the purpose-set forth.
