Description
CONTAINER Filed Oct. 6, 1939 INVEN Patented Apr. 27, 1943( CONTAINER John M. Hothersall, Brooklyn, 'N. Y., assigner to American Can Company, New York, N. Y., a corporation of New Jersey Application october e, 1939, serial No. 298,300
1 Claim.
The present invention relates to containers for the packaging and delivery of liquids, such as milk, fruit juices or the like and has particular reference to sealing the closure of a sanitary libre container.
In certain respects, the invention constitutes an improvement upon the container illustrated and described in my United States Patent 2,085,979, issued July 6, 19'37, and is especially an improvement on further securing and sealing a top closure to make it tamper-proof.
The invention contemplates a liquid-proofed container which comprises a tubular body substantially square in transverse section, having flat top and bottom end members secured to the body by interfolded marginal portions constituting end seam joints in which the parts are permanently united by an interposed suitable liquidproof adhesive to. produce a leak-proof container.
An object of the invention is the provision of a tamper-proof libre container for liquids, such as milk wherein the top endmember, having a dispensing opening, isprovided with a hinged plug closure which is closed and secured at the dairy by a right angled metal band of U shaped cross section embracing the marginal flange of the hinged plug closure member and the end seam joint of the container to prevent accidental 4 opening of the closure or pilfering of .thecontainer contents without being detected by the ultimate consumer.
Numerous other objects and advantages of the invention will be apparent as it is. better understood from the following description, which, taken in connection with the accompanying drawing,-
Fig. 2 is also a view similar to Fig. 1 showing .a modiiied form of sealing band; and
Fig. 3 is a fragmentary enlarged sectional view taken substantially along a vertical plane indicated by lines 3 1 in Fig. 1, illustrating the' container parts in their sealed position:
The container illustrated in the drawing ,shows preferred embodiments of the invention. The drawing shows a container of the general construction describedin detail in my patent hereinbefore mentioned. The container generally comprises a substantially rectangular body Il closed at its ends with suitable top and bottom container contents.
closure members. lThese closure members are similar and for the purpose or this invention.
only the top closure member need be illustrated. The numeral i2 designates such a top closure member. v
The container body Itis preferably formed from a single sheet of liquid-proof brousmaterial folded at right angles'to provide four side walls designated by the numeral i3. The edges of the sheet are joined by a lap seam extending` same ilbrous material as the'body ofA the container. Figure 3 of the drawing shows in detail how the top closure member l2 is interlocked with the adjacent end or marginal portion ofy the body. For this purpose the body marginal end portions are bent inwardly at l5 and thence outwardly as at It thereby providing a seat or ledge il which extends circumferentially of the body and. upon which the closure member is supported. The extreme edges of the body marginal portions further are bent upwardly and thence inwardly from the outer edges'of the closure member to provide a spaced end nange portion I8v .which extends over the margins oi the closure member and seals it in place. The bent or folded parts II, I. of the body adjacent its end and the edges of the-top closure member I2 are permanently secured together with a suitable liquidproof adhesive. This manner of construction provides a liquid tight end seam which is indi-l 'cated by numeral II in Fig. 3 of the drawing.
The top closure member I2 is provided with a dispensing opening 2l (Fig. 3) which is formed adjacent one corner. This opening is preferably closed with a hinge plug closure element 22 having a slightly tapered cup-shaped plug section 23. The hinge closure element 22 is secured to thev top end closure member I2 as by a wire staple arranged to permit the plug closure to swing rearwardly to facilitate both subsequent operations of niling and pouring or dispensing ofthe As in my former patented container, the instant container is also temporarily closed by the Aplug section 23 of the hinge plug closure 22 being inserted into the dispensing opening while the container is empty. This operation is preferably performed in the container manufacturers plant so as to retain the containers in a sterile 'condition before and while being shipped to the dairy or packersv plant for illling and final sealing.
In order to illl the container the plug section 23 of the hinged closure is swung open on its hinged connection or staple 24 to permit iilling the container through the dispensing opening 2 II The lled container is then finally closed by hinging downwardly and re-inserting the plug of the plug hinged closure into the dispensing opening. The shape of the drawn plug may now be slightly altered by a suitable expanding tool to form a clrcumierental bead 2l. 'Ihis bead is pressed out of the plug section directly beneath the under side of the end closure I2 and e'ectively seals and locks the filled container.
Thus far the container as describedis of the same construction as'disclosed in my patent previously mentioned.
The filled and sealed container is now in a suitable condition for receiving'the tamper-prooi' seal constituting the present improvement and particularly designed for the type of container described. Said tamper-proof seal element, is
illustrated as a right angled band of U shaped cross section and is broadly designated by the numeral 28. This band embraces the front end portion of the hinge plug closure element where the latter'extends forwardly of the dispensing lopening 2| as a marginal vilange. This ilange -rests upon the end seam or joint Il and is best illustrated in Fig. 3 of the drawing. The band is further secured while in this position by a plurality of locking tongues 21 which are or may be triangular in shape, having twoadjoining sides cut from the metal band td form a tooth which is bent or struck inwardly and is imbedded in the marginal iiange oi the fibre hinge plug cl'osure element, thereby more securely locking the therefore does not extend beyond the two marginal flange edges ofthe hinge'plug closure 22 element. Such a band, however, also covers and of the drawing, that the metal band 26 securely retains the sealed hinge plug closure 22 ina tamper-proof condition and any piliering of such a sealed container and anyattempt to remove the band and open the closure will be-easily detected and-will anord visual evidence of such action.
It is thought that the invention and many of its attendant advantages will be understood froml the foregoing description, and it will be apparent that various changes may be made in the form,
construction and arrangement of the parts' withtages, the form hereinbefore described beinerv merely a preferred embodiment thereof. I claim: f
A tamper-proof fiber container for liquids,-
comprising a tubular fibre body of substantially square cross section having a fibre tcp end member adhesively secured to an end thereof in an outwardly projecting seam joint overhanging the upper end of said body, a dispensing opening in said end member adjacent a corner thereof' and a closure element hingedly secured to said end member for closing and sealing said opening, said closure element having' a forwardly extendingmarginal flange overlying and secured to said end seam joint adjacent angularly extending portions of the latter, and a metallic sf sling band of substantial channel section and angulaa shape embracing and secured to the localized angularly extending portions only of said'seam joint by means of spaced substantially parallel inwardly projecting portions of said band respectively engaging over the marginal ilange of said closure element and beneath said overhanging seam joint, said sealing band'further including an integral inwardly struck tongue formed in the portion thereof engaging over the marginal ilange of said closure element and penetrating said flange in locking engagement therewith. whereby to maintain said closure element JOHN MHOTHERSALL.
