SEALED PACKAGE AND PARTS THEREOF` Filed Dec. 18, 1953 mma f7 /U/llll, 6" if I ein ATTORNEY Patented Apr. 4, 1939 UNITED STATES PATENT OFFICE 2,153,426 SEALED PACKAGE AND PARTS THEREOF Application December'18, 1933, Serial No. '702,884

12 Claims.

The present invention relates to the sealing art, and more particularly to a sealing -device for containers which cannot be removed Without visible indications thereof.

Screw caps are very desirable for sealing bottles and the like, because of the secure seal and because ofI the ease of application and removal. In addition, the cap can, be used as a. convenient reseal during the consumption of the contents of the package. One serious objection to screw caps, as Well as certain other typesI of caps, is that the contents of the package can he sampled, tampered with, or adulterated and thereafter sold as. an original package. Furthermore, `thecontents can .be removed and an imitation or an inferior A.product can be substituted without knowledge of the consumer. 'I'he package may `also be relled with a substitute after the contents have been used and sold as an original package. These frauds are frequently perpetrated upon the unsuspecting consumers, and more particularly where the packages are sold for a substantial sum. A particularly annoying situation arises in connection with bottles for spirituous liquors, Where the contents are diluted in numerous instances and thereafter sold.

Packers and bottlers advertise the quality of their products and desire that the purchaser obtain their product. The consumers also want to be sure of receiving theproduct purchased and not an infe-rior product or substitute. Thel sale of counterfeit packages is, therefore, highly detrimental to the good will of the packer or bottler. Another serious objection to screw caps is that the caps frequently back off or become loose in shipment and subsequent handling. As a result, the contents are lost andthe `Wrappers of adjacent packages are spoiled or other damage is sustained. a Y

Various attempts have been made to achieve these results and to eliminate the objections of the prior art seals. In most cases, the cost of the resulting package is prohibitive and in other cases the difficulty of removal discourages the use of the cap. I t has been found that consumers do not read orfollow instructions as to the opening of a package; hence, a package difficult to open is not popular. In addition, the consumer demands, in most cases, a convenient reseal. Some bottlers have gone to the extent of providing an over-allfcover cap Which must be torn from the container. This increases substantially the cost of the package.. Frequently. the cover cap does not tear. as it should, and

(Cl. 21S-'7) the part remaining o-n the opening operation, is likely to cut-or injure erson using the package.

The present invention aims to overcome-the above difficulties by providing an inexpensive seal Which cannot be removed without visible indicatons thereof, and by providing means for locking a screw cap on the container to prevent accidental backing off or loosening.k lThe invention also aims to achieve these results Without complicating the removal of the cap or lrequiring instructions therefor, and Without impairing the reseal use of the closure. A

An, object of the present invention is to provide an improved closure which cannot be opened and replaced without visible indications thereof.

Another object of, the invention is to provide a closure which is lockedv against accidental loosening thereof.

Another objectof the invention is to provide an improved closure which cannot be opened and replaced Without the knowledge of the consumer, and toY achievethis result Without impairing the utility of the closure for reseal purposes.

Another object of the invention is to provide a closure which is locked against accidental removal Without impairing its utility as a reseal.

Another object of the invention is to provide an improved closure which cannot be opened and replaced Without visible indications, and which permits the cap to be removed by the usual method of unscrevving.v t

Another object of the invention is to provide a screw cap which is locked against accidental removal and which can be removed by the usual method of unscrewing.

bottle, as well as the the Another 4object of the invention is to provide a sealed package having a closure -c'ap locked in position by a visible frangible member, which is automatically broken by unscrewing the cap.

Another object of the invention is to provide means for automatically locking the cap against removal.

A further object of the invention is to provide a simplainexpensive container adapted to cooperate with the closure to-accomplish the above enumerated objects and advantages.

Other and further/objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be described or Will be indicated in. the accompanying claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

Referring again to the drawing, the several parts of the device are shown more particularly in Fig. 2, and comprise a bottle I, a resilient member 2, a frangible member 4 which may be in the form of a band, sleeve, collar or the like, all of which terms are intended to 4be synonymous when used herein, a ratchet member 5 and a screw cap 6. 'I'hese will be'des'cribed in the order named. 'I'he bottle I may have the usual shoulder I and may be provided with any suitable means for interlocking with the band 4. As illustrated herein, a pair of projections 8 are provided adjacent the shoulder adapted to llt in grooves o-r recesses 9 in the band 4. AA shoulder I8 is provided on the container adapted to seat the resilient member 2. 'Ihe upper end of the container is preferably reduced slightly in size and provided with a thread II adapted to cooperate with the thread on the interior of the cap 6.

' The resilient member 2 is illustrated herein as a coil spring formed from-a suitable Wire. The pressure which the spring exerts is relatively small but is sufficient to urge the ratchet member 5 upwardly. It will be understood, however, that any other suitable means for exerting resilient pressure against the ratchet member 5, when the parts are assembled, may be utilized; for example, a rubber ring may be used, or any other suitable device. The spring, or other resilient member, isY adapted to telescope over the mouth of the bottle and seat upon the shoulder I0 and extend about an enlarged portion I2v on the container below the thread thereof.

'I'he band or collar 4 is preferably formed of a frangible material, for example, a phenolic condensation product or a synthetic resin', which, While having substantial strength, breaks quite easily. Such material is brittle and, unlike glass',

Vdoes not form sharp edges likely to cut or injure the hand. 'I'he grooves or recesses 9, extending axially of the band, serve` a three-fold purpose. First, they are suitably sized to fit over the lugs 8 of the container and thus lock the band against rotation with respect to the container. Secondly, the grooves engage the projections I4 on the Vratchet to lock it against rotation with respect to the band. Thirdly, the grooves weaken the band so that it breaks quite readily. Preferably, either the projections 8 or one side wall of each of the grooves 9, or both the projections and the grooves, are formed Awith a cammed surface I3, here shown on the projections 8 of the container. The purpose` of this inclined or cammed surface, is to cause the projections 8 to attempt to force their way out of the grooves 9 when the cap 6 or the band 4 is rotated backwardly. This expansion is intended to break the band and to give a visible indication of the package having been tampered with. The band may have a suitable trade-mark or design embossed thereon to prevent unauthorized duplication thereof.

The ratchet member 5 preferably comprises a circular collar having ratchet teeth or projections I5 on the upper rim thereof. The projections I4 0n the ratchet fit into the grooves 9, as described above, to hold the ratchet in position. Ihe ratchet member 5 may be made of any suitable material but, as illustrated herein, it is also made of molded material such as synthetic resins. It Would be obvious, however, that other types of material could be used and their uses are contemplated herein.

The closure cap 6 may be of any suitable shape. As here shown, it comprises a cover portion I6 and a depending skirt I'I with suitable screw threads I8 on the interior thereof. The inner part of the skirt is extended downwardly at I9 and is provided with ratchet projections 2U 'on the bottom of the extension. These ratchet projections are adapted to engage and cooperate with projections member 5. The outer portion of the skirt may terminate in a shoulder 2| adapted to abut the upper end of a frangible sleeve or collar 4. While the closure cap may be made of various materials, the construction shown is a molded cap preferably made of a phenolic condensation product or a synthetic resin. Such caps may be molded in the form shown by stripping the caps from the molding pins before the caps have been completely cooled, the elasticity of the mal terial before it has completely' hardened or set being utilized to permit the cap to jump over the threads on the pin. A'suitable liner 22, of cork or other material, may be utilized as the sealing element between the rim of the container and the cover part of the cap. Any other suitable sealing means may be utilised, for example, rubber, felt, cardboard and similar materials.

While the parts herein may be assembledY in any desired way, one convenient way is to drop the coiled spring 2 over the end of the container so that it rests on the shoulder I0 about the enlarged portion I2, thereafter the collar or sleeve 4 may be telescoped over both the spring and the end of the container and t-he grooves 9 made'to register with the projections 8 so that the bottom of the collar rests upon the shoulder 'I ofthe container. Thereafter, the ratchet member 5 may be dropped over the end of the container and the projections I4 may be placed into the grooves 9 on the interior of the frangible collar or sleeve 4; preferably the spring 2 is not sufficiently large to force the ratchet member 5 out' of the collar, but permits it to rest in the upper part thereof with the projections I4 in registry with the grooves 9. 'I'he cap 6 is then screwed'upon the container in the usual manner. The ratchet projections 20 engage the projections I5 on the ratchet member 5 and the rotation of the cap is continued with the usual ratchet sound until the cap is screwed home. In this position, the bottom of the skirt of the cap 2I abuts the upper end of the collar 4. The ratchet teeth 20 on the cap extend sufciently far down into the collar member 4 to prevent one from using a pin or other instrument to pry into the cap and push down the ratchet so that the cap can be removed without breaking the collar 4. The assembly of the parts is I5 on the ratchet shown in section in Fig. 1 and in elevation in Fig. 4.

In removing the cap, one takes the package in the usual manner and unscrews the cap 6. It is immaterial whether the person grips just the skirt of the cap 6, or the entire cap and band In either case, backward rotation of the cap or the band will cause the band to attempt to ride over the projections 8 on the container, and the outward pressure at Athe projections 8 causes the band to break, as shown more particularly in Fig. 5. After the band breaks, the cap proper may be rotated either alone or together with the broken band 4, and the cap removed. After removal of the cap, the band 4 and spring 2 and ratchet member 5 are preferably removed from the neck of the bottle and thereafter the cap 6 is utilized as an ordinary screw cap for reseal purposes, as shown more particularly in Fig. 6. It will be noted in Fig. 6 that the removal of the partsjexcepting the cap, is very noticeable and the consumer willy immediately know that such a package has been tampered with. In fact, the consumerV learns to listen for the cracking noise of the frangible collar, also enjoys breaking the collar. A break 23 in the collar, as shown in Fig. 5 is readily noticeable and prevents any attempt being made to pass such a package as an" original package. In addition to being tamper-proof, the cap is locked in position so that it cannot become loose during shipment and handling, which is an important feature.

It will be seen that the present invention provides a sealing device in which the several parts may be readily and inexpensively manufactured and easily assembled. The closure cap is applied in the same manner as any ordinary closure cap and is likewise removed as a screw cap is removed. No directions are necessary for the consumer in opening the package. In addition, the cap is locked against loosening during shipmentor improper removal by persons desiring to tamper with the contents. The frangible band 4 is readily broken without materially increasing rthe turning effort necessary to remove the cap. The material of the band prevents cutting the hands or otherwise injuring the person removing the cap. The band 4 may be, if desired, given a contrasting color. For example, the cap may be black, the band red, or any desired colors may be utilized, since a synthetic resin may be made in almost any color. To further assure the customer that the package is genuine, both the band and the cap may be embossed with the packers trade-mark or any other decoration desired. Such embossment on the band may be stripped from the mold, as described above with respect to the closure cap.

As various changes may be made in the material used, dimensions, relative proportion and the construction of the several parts described herein without departing from the spirit and scope oi the invention and without sacrificing its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in a limited sense, as the scope of the invention is to be coextensive with the scope of the claims.
