Claims.
" the contents of the bottle when being poured out. A further object is to provide means for scaling to the bottle a bottle cap having a skirted pouring lip housing so that the skirt is sealed to the 1 bottle neck below it, reinforcing the skirt against flaring and preventing the entry of foreign-matter between it and the bottle. These and other desirable objects are obtained by applying to thecapped bottle a strip of sealing For amore complete understanding of this in vention, reference may be had to the accompanying drawing in which Figure 1 is a somewhat diagrammatic view of Y 30 a milk bottle to which a cover-all cap has been applied and showing the application thereto oi. the sealing strip.
caps are commonly formed of a paper composi- Y, on suitably moisture proofed, being formed up ls rom a paper disk with its edges folded together granted March 1, 1927. a o The skirt extends downwardly about the outer face of the bottle to such an extent as to bring its lower edge which is thick enough to form a substantial shoulder adjacent to a portion 4 of the bottleneck which-progressively is of reduced diameter for a distance from the top of the the bottle.
entry of foreign matter in between the' skirt and it conforms automarelation as shown at 6 and there secured to 'gether, the cap is securely sealed to the bottle. This winding is shown as accomplished by hand.
should be non-porous and self-sealing of the overlapped ends of the ,ma-
rubber compositions such as hydrohalides in combination with wax such as Such compositions, more particularly of chlorinated rubber, are marketed under various trade names, one of which is Pliofilm. A material particularly suitable is known ll without heat, and is waterproof.
2 Y i neonate in the trade as Parafllm and is a composition of rubber and wax,this material being manufactured by the Marathon Paper Mills Company of Rothschild, Wisconsin. This material is described in United States Letters Patent No. 2,054,112 and No. 2,054,115 et a1. September 15, 1936, and is particularly suitable since it will stretch up to about 100%, seals on itself under pressure, either with or adhere strongly to either the bottle or the bottle cap, but theadhesion to itself is sufiicient to hold it in place when wound under tension as here;- tofore described.
16 A milk bottle is under particularly favorable conditions forthe avoidance of adhesion of materials such as described which are somewhat heat sensitive and which are moisture proof, in
that the bottle as it passes from the filling me.-
20 chine is cold and commonly wet over that por-' tion where the sealing film will be applied, so that under such conditions it affords a surface repellent to thermoplastic adhesive agents of the film material which are of utility for efie'cting selfsealing of theoverlapped ends of the film together. Such film materials are so thin that they afford little resistance to turning of the cap when it is desired to open the bottle, but such turning of the cap so destroys their continuity that. it is very evident when the bottle has been opened.
Furthermore, the film being wound under tension about the skirt of the cap retains this skirt in closed condition against the bottle, insuring against any tendency to fiare due to rough handling or, since it is waterproof, to the entry of moisture into the cap material should the cap not be thoroughly waterproof. Due to the lack of adhesion of the film to both the bottle and to 40 the cap, the sealing of the overlapping ends of the strip to each other constitutes the major portion of the securement of the strip in sealing position. These various materials may be procured in different colors so that besides effecting a seal impervious to' moisture and providing evidence of tampering should the cap have been removed, they may produce a highly ornamental efiect.
From the foregoing description of the method of this invention and certain embodiments thereof it should be evident to those skilled in the art that various changes and modifications might be made without departing from the spirit or scope of this invention as defined by the appended claims.

2. In combination, a. container having a closure cap provided with a skirt engaging the outside of the container below its top, a strip of sealing film surrounding and contacting said con- 10 tainer and in overlapping relation to said skirt and with its ends in overlapping relation to each other, said film being formed of extensible material consisting of a thermoplastic composition which is heat sealable onto itself and is not suffl- 15 ciently adherent-to either the container or cap 1 to be secured thereto by adhesion, said strip being 7 held under sufficiet tension to be conformed to the contour of the container and cap, and being secured substantially solely by the sealing of its 20 ends together. v
3. In combination, a container having a closure cap provided with a skirt engaging the outside of the container below its top, a strip of sealing film surrounding and contacting said con- 25. tainer and in overlapping relation to said and with its ends in overlapping relation to'each other, said film being formed of extensible material consisting ofa wax-rubber composition which is heat sealable-ontoitself'andis not 30 sufficiently adherent to either the container or cap to be secured thereto by adhesion, said stripbeing held under suflicient tension to be conformed to thecontour of the container and cap, and being secured substantially solely sealing of its ends together.
4. In combination, a container having a clo-' sure cap provided with a skirt engaging the outside of the container below its top, the capskirt being thick enough to form a substantial shoul b der at the lower edgethereof, and a strip of sealing film surrounding and contacting said container and in overlapping relation to said and withits ends in overlapping relation-to each other, said film being formed of extensible ma- 45 terial consisting of a rubber composition which is sealable onto itself and is not suificiently adherent to either the container or cap to be secured thereto by adhesion, said strip being held under' sufficient, tension to be conformed to the 50 contour of the container and cap and the shoulder formed by the lower edge of the cap skirt, and being secured substantially solely by the sealing of its ends together.
.5. In combination, a container having a closure 55 cap provided with a skirt engaging the outside or the container/below its top, a strip of sealing. film surrounding and contacting said container and in overlapping relation to said skirt and with its ends in overlapping relation to each othensaid 60 film being formed ofextensible material consisting of a rubber composition which is sealable onto itself and is not sumciently adherent to either the I container or cap to be secured thereto by adhesion, said strip being held under sufiicient tension 5 to be conformed to the contour of the container I j and cap, and being secured substantially, solely a by the sealing of itsendstogether.
