Hans 0. Irmscher,
New York 'New York, N.' Y., assigner to Millie Plfent Holding Inc., a corporation of Application May 26, 1938, Serial N0. 210,152 10 Claims. (Cl. 93-3) This invention relates in the manufacture and nlling oi' containers or bags. Although in prac-v tising the invention containers or bags may be l' made for use to package various materials, the
embodiment of the invention as herein described is directed to the packaging of tea, coii'ee and similar essence containing products made and sold as complete articles of manufacture for use in brewing beverages, as for example, in making so-called tea-balls in packages or bags formed of crease-retaining sheet material, such as illter paper or perforated vegetable parchment paper and Cellophane, and is also directed to the novel method of producing the same.
Among theobiects of the invention is to generally improve packages of the character described and the methods of manufacturing same. which shall have joint seams formed by folding and creasing alone, said seams being 4ilrmiy retained against separation without the use of any adhesives, which shall comprise of few and simple fastenings arranged to provide an inexpensive article of new. neat and attractive appearance, the improved method of manufacture lof lwhich shall be particularly adapted for large scale production, and which method and article shall be efcient and practical to a high degree. Other objects of the invention will in part be obvious and in part hereinafter pointed out. The
invention accordingly consists of features of construction and method, combinations of elements, arrangements of parts and steps in the process of manufacture which will be exemplified in the construction and method hereinafter described and of which the scope of the application will be indicated in the following claims. l
In' the accompanying drawing in which is shown various possible illustrative embodiments Figs. 1 and 1a are perspective views showing an unperforated and perforated sheet material, respectively, in cut blanks for use in practising the invention:
Fig. 2 is a perspective view of a blank wrapped around a form to provide a seamed tubular structure;
Fig. 3 is a view similar to Fig. 2 showing the tubular structure provided with a bottom closure:
Fig. 4 is a fragmentary cross-sectional view of the seam taken on lines 4-4 in Fig. 3;
Fig. 5 is a front elevational view of the partially lled bag in bottom closure tucked in and the top closure flaps infolded. the dot and dash lines indicating ilattened condition with the the position of the flaps before being infolded; Fig. 6 is a cross-sectional view taken on lines 6 6 in Fig. 5,'
Fig. 7 is similar to Fig. 6 but shows the nishing lof the top closure stapled to anchor the string handle; Fig. 8 is a perspective view showing a completed tea-ball made in accordance with the invention; and
Fig. 9 is a perspective view showing a tea-ball during brewing operations in an expanded condition and the control of the drip therefrom.
Referring in detail to the drawing l0 denotes a tea bag manufactured and constructed to embody the invention.
In practising the embodiment of the invention for making tea-balls I0, a suitable sheet material il may be used 'either cut from a roll or precut in strips `or blanks of required size in the well understood manner. Said sheet material when" used merely as a protective cover in embodiments of the invention for small packages of any product other than here shown may be made of any of the various commercially obtainable forms of paper, Glassine or Cellophane. In practising the invention for makinar tea-balls, however, wherethe product contains an essence to be extracted by brewing and-the like, there lmay be used as the sheet material, suitable filterpaper l i of a character that will withstand emersion in boiling water without damage or disintegration. or said sheet material may be made of vegetable parchment paper or Cellophane I2 finely perforated as at I3 td permit passing therethrough liquids forming the brew with the contents of the package.
In carrying Out the improved method for making tea-balls I0, a strip of sheet material il or I2 may preferably be applied to or wrapped around a hollow form F and joined by creasing and folding aligning edge portions that extend lengthwise thereof as showny in Figs. 2, 3 and 4 to provide a tubular structure Il. Said creased and folded joint portions form a seam II for the tubular structure I4 without the use of any adhesives or other securing means. The lower end Ila of the tubular structure Il, which is seen in Fig. 2 to extend beyond the form F, may
' next be infolded all around and the extreme end of the portion infolded gathered together to make a bottom closure lib. A metallic staple or band IB or other suitable securing means is then applied to the gathered to form a bag I1 as shown in Fig. 3, The infolding 4oi' the end Vportion ila as above described provides a cross fold at lia which retains the seam I against separation.
Next the bag II as now formed is partially filled with a product T, such as tea through the center of the hollow form F. Thereafter the filled bag I1 is removed from the form F, preferablyV simultaneously with such removal of said filled bag I'I from the form F, the bottom closure Mb may be tuckedy in, and the filled bag I1 attened so that the staple or band I8 and gathered portion is concealed from view as shown in Figs. 5 and 8. The other or top end portion of the partially filled flattened bag I1, shown in the dot and dash line position in Fig. 5, is next infolded from opposite longitudinally extending single fold creased edges Ilb to provide flaps I9 which preferably have edges thereof come into a position of abutment or slight overlapping as shown in Fig. 5 at 20 in dotted lines and form a tapered shaped end for the package as shown in Figs. 5 and 8. Each of the unfolded at tapered sides of the bag is then cross-folded at 2| and 22l to cover any openings at the Joint 20 between the aps I9. The fold at 2l which extends across the seam I5 serves to retain and co-act with the fold I5a. on the bottom closure Mb for retaining in laundry work and also in household and facfv f the seam I5 against separation to assure that the joint at said seam l5 stays tight. A small staple 28 or other anchoring means may be applied to retain the folds at 2i and 22 together to make the top closure tight and form an additional securing means for said seam I5. Where a string handle 24 and tag 25 is used on the package as in making tea-balls I0, an end of the string handle is anchored by the staple 23 as shown in Figs. 'I and 8.
The tea-ball I0 made by the improved method and construction above described can be utilized in the well-known manner by holding the string handle 24 and immersing the tea-ball Il) in a cup C or like container having preferably water at boiling temperature to make a brew in the well understood manner. As the tea-ball i0 is lifted out of the cup to drain the brewing liquid, the bottom end of the tea-ball is expanded from its normally flattened condition and the draining will take place by the brew following the gathers at the bottom closure Mb dripping from the teaball Iii in a guided stream from the end adjacent the staple I6 as shown in Fig. 9. Thus itis seen that the dripping is facilitated and conned so that it can easily be managed, a feature greatly desired in this type of article as it aids in avoiding accidental spillage.
As seen from Fig. 8 the tea-ballv I0 as supplied to thel user is in a flat compact condition with the bottom closure IIb tucked in and concealed, the longitudinal edges I1b formed with smooth single folds, and a seam I5 extending across the middle of one of the fiat surfaces of the tea-ball I0, said seam I5 forming a bracing as well as an ornamental trimming. The top closure of the tea-ball I0 is formed with tapered infolded flaps I9 which are also concealed, a string handle 24 and tag 25 being anchored at the staple 23 which secures the folds 2l and 22 of the top closure, the entire construction forming a harmoniously shaped article which is neat and attractive in appearance.
As stated above the embodiment of the invention shown in the drawing and described herein is directed to the manufacture of a package for brewing, such as a tea-ball. It is to be understood, however, that the identical package may be utilized for blueing or otherwise tinting clothes tory dyeing operations. Packages for dispensing various dry products, samples thereof. medicinal products and the like, may be manufactured in accordance with the invention using sheet materials that are not to be immersed in liquids but on the contrary may be moisture-proof. Such package may be made with or without string handles.
It is thus therefore seen that there is provided an improved article of manufacture and a method for making the same in which the objects of the invention are achieved and which are well adapted to meet all conditions of practical use.
As various possible embodiments may be made in the above invention for use for different purposes and as various changes might be made in the embodiments and method above set forth, it is understood that all the above Vmatters here set forth or shown in the accompanying drawing are to be interpreted as illustrative and not in a limiting sense.
