TEA BALL.

Application filed October 8, 1923. Serial No. 667,239.

particularly the invention relates to a class of perforated metal containers adapted to fully inclose a suflicient quantity of the material for individual requirements.

One of the objects of the invention is to provide a container of simple construction that may be made from a single blank or sheet of material without waste thereof.

A. further object is to provide a container having a shape adapted to olfcr the greatest strength and resistance for the amount of material used in its formation, thus permitting the use of relatively thin material in its construction.

A further object is to provide a container having similar triangular faces which when turned or agitated will permit the contents to freely flow by gravity to the lowermost face.

A further object is to provide means for movably suspending or agitating the container, or allowing the same to rest upon any one of its several faces to effect a more rapid infusing action.

A further object is to provide a method of construction whereby the container may be formed into the desired shape from a single piece of material.

A further object is to provide in the construction of the container an open mouth through which the material may be inserted and closed therein by joining together the upper edges of the container.

For further comprehension of the invension, and of the objects and advantages thereof, reference is had to the following description and accompanying drawings and to the appended claims in which the various features of the invention are more particularly pointed out.

Figure 1 of the drawings is a view showing an extended blank from which the improved t-eaball is adapted to be made.

Figure 2 is an end view showing a step in the construction in which the blank is shaped tubular, with its opposite ends joined together by a seam.

Figs. 3, a, and 5 show respectively side, end, and edge views of the next following step in which the opposite plates at the lower end of the tube is contracted in wedge form, with a tag-string introduced therebetween.

Figs. 6 and 7 show views corresponding respectively with Figs. 8 and land which further show the edges of the contracted plates joined together with a double seam, and the tag-string doubled up with the seam and secured thereby, the opposite end of the tube being leftopen at this step for introducing the material to be enclosed.

Figs. Sand 9 show views corresponding respectively with Figs. 6 and 7 and which also show the opposite plates at the opposite or upper end of the tube to be similarly contracted in wedge form, and as indicated from the broken lines 8 the contraction from the latter position causes the plates to be extended in a right-angle direction as indicated in Fig. 9.

Figs. 10 and 11 show views corresponding respectively with Figs. 8 and 9 and which also show the upper edges of the plates as being seamed over to securely seal the contents of the container. Y

As shown in the drawings numeral 10 designates a blank consisting of a rectangular piece of relatively thin material, preferably aluminum foil, provided with suit ably disposed perforations 11, and score lines 12 the latter being arranged in triangular relation corresponding with the bends or folds to be made in the blank.

In the formation of the article the blank is first folded over in tubular form with the ends 13 joined together and forming, as shown in Fig. 2, a seam 1.4, the score lines 12 dividing the surface of the tube into four equal triangular spaces. The side walls of the tube at its lower end are then closed to gether, a tag-string or corresponding flexible connection 15 being interposed therebetween, as shown in Figs. 3, 4 and 5, the lower end of the walls being then folded over to form a double seam 16, adapted to form a closed joint and securely hold the string as indicated in Figs. 6 and 7. At this point in the forming operation the upper end 17 of the tube will be left open to receive the material to be inclosed and after the same has been inserted the upper edges of the tube will be closed together as shown in Figs. 8 and 9 and provided with a seam 18 adapted to securely retain the contents within the container, the closed seam being indicated in Figs. 10 and 11 which show side views of the finished container taken at right angles to each other.

It will also be seen that the closing operations of the lower and upper edges of the tube are made respectively at right angles to each other, and that the effect thereof is to bend the tube. along the corresponding score lines 12 and form a closed container having four triangular perforated faces adapted by means of the flexible cord or connection to be immersed in a liquid for obtaining the desired infusion.

lVhat 1 claim as my invention and desire to scour by Letters Patent, is:

1. A receptacle-blank comprising a single piece of material in theform of an oblong plane quadrilateral, the same being scored in zigzag lines extending lengthwise of the blank and obliquely of the sides thereof, the ends of said lines being spaced from the sides of said blank.

2. A receptacle-blank comprising a single piece of perforated material in the form of an oblong plane quadrilateral, the same being scored in zigzag lines extending lengthwise of the blank and obliquely with the sides thereof, the ends of said lines being spaced from the sides of said blank.

3. A receptacle-blank comprising a single piece of perforated metal in the form of an oblong plane quadrilateral, the same being scored in zigzag lines extending lengthwise of the blank and obliquely with the sides thereof, the ends of said lines being spaced from the sides of said blank.

f. A tea-ball comprising a perforated receptacle formed of a single rectangular strip of material shaped to form four pyramidal triangular faces, the edges of the strip being joined together and forming a closed retainer.

5. A tea ball comprising a perforated receptacle formed of a single rectangular strip of aluminum foil shaped to form four pyramidal triangular faces, the edges of the strip being joined together and forming a closed container.

6. A tea ball comprising a perforated receptacle fromed of a single rectangular strip of material shaped to form four pyramidal triangular faces, the edges of the strip being joined together and forming a closed container and a flexible connection secured thereto.

7. A tea ball comprising a perforated receptacle formed of a single rectangular strip of material shaped to form four pyramidal triangular faces, the edges of the strip being joined together to form a closed container, one of the joints of said faces constituting a double seam, and a flexible connection secured to the container by said double seam.

Signed at New York in the county of New York and State of New York this 5th day of October A. D. 1923.
