Other objects of the invention will in part be obvious and in part hereinafter pointed out.
The invention accordingly comprises the steps ofthe manufacturing method and features of constructions, combinations of elements and arrangements of parts which will be exemplified in the method and constructions hereinafter disclosed, the scope of the application of which will be indicated in the claims following.
lIn the accompanying drawing in which possible illustrative embodiments of the invention are shown:
Figs. 1 and 2 are enlarged front and rear elevational views, respectively, of a tea bag manufactured with a non-tangling temporarilyretained looped configuration string-handle and tag for cartoning and as delivered to the consumer for use in a sanitary manner.

Figs. 6 and 7 are enlarged front and rear elevational views, respectively, of the modified form of tea bag shown in Fig. 5 with the string-handle and tag arranged in a 2,819,167 Patented Jan. 7, 1958 ICC Von in a cup and also to provide a tag which bears a legend or trademark of the manufacture, grade of tea, etc. -In order to eliminate dangling of the string-handle and tag which often results in accidental tearing of the bag when cartoning and handling when individually removed for use and to provide a neat and attractive tea package delivered to the user, various temporary retaining means have been devised.
The present invention, like those shown and described in my previous Patent No. 2,490,057, granted December 6, 1949, and my co-pending application, Serial No. 306,764, iile'd August 28, 1952, is intended to provide a practical construction for producing an infusion package with a non-tangling string-handle.
Referring in detail to the drawing, 10 denotes a iilled infusion package embodying the invention constructed inthe form of a square, that is, pillow-shaped, tea bag body portion 11 provided with a non-tangling stringhandle 12 and tag 13 temporarily retained in a slip looped configuration engagementwith an anchored string-handle end 12a made readily releasable by simply applying a pulling or lifting force Without putting tearing strains o n heat-sealed top closure seam ange 11a of said body portion 11 on which the string-handle end 12a is anchored'b'y staple 14.
'As is clear from Figs. 1 to 4, tea ball 10 may have body portion 11 thereof made of a suitable thin lter sheet material strip folded over on itself to provide a rounded bottom edge 11b forming superimposed layer vportions to provide front and rear flattened sides 11c and 11d, respectively, of body portion 11, said sides 11e and 11d being secured along the marginal areas on the remaining three edge portions with seam flange 11a forming said top closure extending between spaced apart parallelly aligned seam ilanges 11e and 11j to completely seal contents T in body portion 11.
Tea bag body portion 11 may be constructed of a suitable foraminous sheet material, as for example, lter paper, coated for heat-sealing more fully described in my said Patent No. 2,490,057.
Unlike theV construction of the `non-tangling stringhandle retaining means disclosed in my said Patent No. 2,490,057, heat-sealed top closure seam flange 11a is left unslit and otherwise uncut so that tearing strains to which the package structure may be subjected in use at and about anchoring staple 14 can be reduced to a minimum in the construction embodying the invention.
String-handle end 12a is attached to top closure seam flange 11a by staple 14 in a double, overcast locked anchorage, that is, the free end of string-handle 12 passes under staple 14 on body portion rear side 11d, then loops over the extreme edge of top closure seam ange 11a as at overcast portion 12b and' again passes under staple 14 on body portion front side 11e to complete the double anchorage. l
In the non-tangling shortened position shown in Figs. 1, 2, and 3 elongated mid-portion 12e of string-handle 12, after leaving said double anchorage, extends under, that is, through overcast portion 12b in a hitch, that is, slip knot configuration at 12e and over said extreme edge of seam flange 11a to lie against body portion rear side 11d as large loop 12d. The end portion 12f of stringhandle 12 adjacent tag 13 repasses through overcast portion 12b and over said extreme edge of seam flange 11a knot condi" 1% byondend portion 12). in any suitable manner, such Blf-'staples' oir,l as here shown, 'tag i3 is of re1auve1y thin ub1ewiftnr'sin coated paper stock folded over "and heat-sealed together onto string-handle 12 as fully described in my said co-pending application Ser. No.
inyention may be practiced by applying stringhandlesY 12 With tags 13 to top closure seam ilanges 11a 'of tea. bag. body portions 11 each heat-sealed with contents T by means of staples 14 with said double anchorages prgviding string-handle overcast portions 12b on a highv speed tea bag manufacturing apparatus fully described in my said tio-pending application Ser. No. 306,764, after whichl each string-handle mid-portion 12C is inseited `th'r'cmgli each of said overcast portions 12b finishi'ng` 'filled tea bag packages 10 with the non-tangling shortened string-handles and tags as shown in Figs. l, 2 and 3 and thereby permitting unobstructive advancenient throughI said manufacturing apparatus for automatic cai-toning and delivering tea bag packages 10 to the user in aI 'non-tangled shortened condition.
The tea'bag package 10 may be removed from an envelope or carton container without fingering body portion 11v by simply picking up tag 13 so that the weight ofthe filled package readily pulls large loop 12a' through overcast portion 12b from its temporary trictional retained position permitting suspension of body portion 11 `bythe entire lengtli'` of string-handle 12 as shown in Fig. 4t'liereb`y aiding a's a sanitary method for manipulating 'in brewing in the well understood. manner.
The methodetnbodying the invention will now be apparent.Afte r` forming filled tea ,bag body portion 11 wthheat-'iseald top closure seam flange 11a, string-handle 12 with tag 13 previously attached to one end thereof isn'securedto seamYA flange` 11aby arranging the stringpfiosi'te,l kAtag', 13 in an overcast position I l e' 'thereto' 't s'e'r've as. said double anchor- 'agewith -tiring-lian dlef,overcastI portion 12b extending ver( edge", f s'e'In-ilangel 11a. String-handle tnidportion 1.2;2 then'4 inserted under overcast portion Iz'bqapn'arja sthrhghgin a 'mrionauylemined slip tioned' to. lie nat against lrear side 11d with tag 13 against front'- side 11i-' l A modified form embodying" the invention is Yshown 'as tea bag package 20 in'Figs.. 5, 6, 7 and 8 t9 comprise body portion 21 provided with a rounded bottornedge 217; forming superimposed layer portions as front and rear `flattened sides 21e` and 21d, respectively, of body I iQlonZl and side seam ilanges 21e and 21f for containing contents T, all similar to the corresponding parts of te' bag package 10.
instead of utilizing a stapleV for attaching string-handle end22a, the latter in a serpentine configuration is placed between an upper margin portion of sides 21a and 21d and heat-sealed therein duringfthe bag closing operation forming vheat-sealed top closure seam flange 21a as a string-handle anchorage.
n order to'. provide a non-tangling string-handle retaining means embodying the invention, the serpentine configuration of string-handle end, 22a is so arranged when heat-sealed into seam flange 21a as to provide an auxiliary loop portion 22b extending beyond the extreme edge of top closure seam tlange 21a, as is clear from Fig. 5.
In the non-tangling shortened position shown in Figs. 6, 7 and 8, elongated mid-portion 22e of string-handle 22 after emerging for a second time from seam flange 21a extends in slip knot conguration as at 22e through auxiliary loop portion 22' and over vsaid extreme edge of seam flange 21a to lie against body portion rear side 21d as large loop 22d to large loop 12d of package 10 The end portion 22j of string-handle 22 adjanntilfst'ring-li'andle large loop 12d is posicent tag 23 repasses through auxiliary loop portionu22b and over said et'elne edge f seam Hnge ^2in einpleting said slip knot configuration to position tag 23 at against body portion front side 21e similar to tag 13 in package 10.
In the method of manufacturing tea bag package 20, string-handle end 22a is positioned between the lupper margins of front and rear sides 21e and 21d, respectively, in a serpentine configuration for forming said auxiliary loop portion 22b and is then anchored therebetween simultaneously with the heat-sealing ofin the top closure of filled body portion 21 forming seam flange 21a. Stringhandle mid-portion 22C is then inserted through auxiliary loop portion 22b and drawn through in a frictionally retained slip knot condition until string-handle large loop 22d is positioned to lie flat against rear side 21d with tag 23 against front side 21C in a manner similar to the insertion of string-handle mid-portion 12e under overcast portion 12b in forming package 10.
Tea bag package 20 may be removed from its envelope or carton container without nngering body portion 21 in the same manner as hereinbefore described for package l0. y
It is thus seen that there are provided improved infusion packages with non-tangling string-handlesand tags and a method for manufacturing same in which the sev eral objects of the invention are achieved and which are well adapted to meet the conditions of practical use. l
As various possible embodiments might be madein the above invention, and as various changes might be made in the constructions and. method. above set forth, it is to be understood that all mattersV herein. setnforth or shown in the accompanying drawings areto beginterpreted'as illustrative and not in a limiting sense.
