United States PatentO seats: V .lNrusroNrAckAon. v Joseph V. Maloney,'Frankl in, Ind. Application February 27, 19512, Serial No. 273,517- 6 CIaims (crane- 0.5

This invention relates to an infusioncontainer adapted for useas a single-service package, embodying an envelope 'or bag containinga quantity of tea, coffee, -or other infusion material, and a dished receptacle pivotally connectedthereto. w i

In the Well knownand widely-used tea bag, the tea is contained in a bag or envelope which is connected'by a string'to a tag or label. The tag and'the string are used to manipulate the bag, to immerse it in a cup or pot of hot water or other infusion liquid, and especially to withdraw it therefrom when the 'brew has reached the desiredstrength. Such bags, with their attached strings,

present an awkward problem in packaging, for the strings tend to become entangled and the user has difficulty separating one bag from a group in the package.

In use,.especially at the dining table, when the*bag is withdrawn from theliquid in a cup, the useris presented with a troublesome" problem of what to do with the wet and dripping bag." Usually, the bag is'put in the saucer, with the result that liquid drains from it'to the bottom of the saucer and wets the bottom of the cup, and when theuser lifts the cup to drink from it, the cup drips.

It is an object of my invention to provide an infusion container or single-service package which will include a bag that may beused in.the same general way as prior 2,698,082 Patented Dec. 28, 1954 Fig.- 3 isan isometric view of an infusion package embodying my invention, in which the bag is attached to the receptacle byastapleg Fig. 4 is an isometricview showing a package embodying my"invention,-in' which-the connected end of the bag is received beneath'a bentover tab on the receptacle, and in which the parts areheld together by a-staple;'and

Fig. 5 is a view similar to Fig. 4 in which the parts are held together by a water-insoluble adhesive.

The infusion bag shown in the drawing is in the form of a rectangular envelope desirably of somewhat greater length than width and containing a single-service quantity 11 of tea, coffee, or other infusion'material. The attached end of the bag 10 desirably has a flat marginal portion 12 somewhat-wider than that at other edges of the bag, but otherwisethe bag closely resembles an teabags, in combination with areceptacle directly connected to' it to form a unitary package. It is an object of my invention to..provide..a unitary package which will conveniently stackwithothers inaggroup package. and will be easily separated and removed therefrom. It is an object of my invention to provide a combined infusion bag and dished receptacle so related that the unit may be manipulated with one hand to immerse the bag in a cup or pot of liquid and to withdraw the bag therefrom, and so related that a simple pivotal movement of the receptacle as the unit is withdrawn will cause the wet bag to enter the receptacle and be so received therein that the unit may be set on the table with the bag and its drippings wholly contained in the receptacle.

In accordance with my invention, I provide a dished receptacle, preferably (but not necessarily) of rectangular shape and preferably with a handle tab along one edge, with the receptacle of a size to receive a bag containing the infusion material; I place a bag therein, preferably with a flat marginal portion of the bag lying against the tab of the receptacle; and I join the bag to the receptacle at one edge, preferably at the tab, by a direct pivotal connection. The receptacle contains the dry bag during packaging and distribution, and may be nested with others in a market-size package; and the direct pivotal connection provides that after use the receptacle can be moved with one hand through a simple pivotal movement as by its handle tab, to cause the wet bag to enter the receptacle in a position where both it and any drainings from it will be contained in the receptacle. The receptacle is desirably made of a liquid-impervious --material, and may have an absorbent inner surface or lining. The receptacle serves as a convenient label, to carry printed instructions and other label information.

The accompanying drawing illustrates my invention. In such drawing:

Fig. 1 is a perspective view showing the operation of immersing in a cup of liquid the infusion bag of a package embodying my invention;

jg. 2- is a side elevation with parts in section, showing the bag in position in a cup of liquid;

envelope type bag of a type now on the market. Because of this resemblance, the'bag I use-may bemade on-the same machines as those now in use, indeed the bag itself may be identical with those of this type now on the market. The bag 10 is attached by its marginal end '12 to a dished receptacle 14, with the bag'10 resting in the receptacle 14 as-shownin Figs. 3 to 5. The receptacle 14 is desirably of sufficient volume to contain the filled portion of the bag wholly below the-plane of itstop edges, and is of suificientrigidity to be seuf-sustaining and to permit it to be handled in the manner noted below.

Desirably, the receptacle has an outwardly extending tab 16 at one end, to which the bag 10 may be attached and which serves as a handle for the container. The receptacle maybe made'of any of a number of materials, and by various methods. Conveniently, it may be molded ofpaper or plastic stock. The stock may be water resistant, or may be given a water resistant coating. It may be made of water-absorbent stock, and coated only on the outside so that after use it will absorb liquid which drains from the wet bag. Both the bag and the receptacle should be made of taste free material, to avoid contaminating the taste of the infusion material.

The receptacle 14 may be of any desired shape. It is desirably of the rectangular tray-like'shape as shown, especially when it is combined with a recentagular envelope-type bag. Its bottom is flat, or otherwise formed to provide a stable base on which it may rest in upright, liquid-retaining position. It is desirably somewhat longer and wider than the bag so that the bag 10 will not project beyond its sides or ends.

In Fig. 3, the bag 10 is attached to the single-layer tab 16 by a single staple 18, positioned parallel to the attached edge of the bag 12 and parallel to the edge of the tab 16. In Fig. 4, the receptacle 14 is provided with a somewhat longer tab 16 the outer end 20 of which is bent over the edge 12 of the bag 10 and held by a single staple 22.

Instead of a staple to connect the tea bag 10 and receptacle 14, a water-insoluble adhesive may be used, in either of the arrangements of Figs. 3 and 4, whether or not a tab portion is bent over the marginal edge 12 of the bag. The use of adhesive is illustrated in Fig. 5. As in Fig. 4, the receptacle 14 carries an elongated tab 16 whose outer end 24 is bent over the edge 12 of the bag 10. Here, however, the inner surfaces of the tab and its overlying portion 24 are coated with adhesive 25 which is caused to adhere to the opposite faces of the marginal edge 12 of the bag 10.

Various other attaching means may be used. For example, the porous material from which some tea bags now on the market are made is coated or impregnated with a heatsensitive adhesive, which under the application of heat and pressure closes the edges of the tea bag. With an infusion bag of this material, the marginal end 12 of the bag may be attached to a tab or edge of the receptacle 14 by a similar application of heat and pressure.

The attachment between the bag 10 and the receptacle 14 provides a pivotal connection therebetween, and desirably a hinge-type connection in which the parts are constrained to relative movement about a single transverse pivotal axis, indicated by a dashed line A-A in Fig. 3. In that Fig. 3, the constraint to relative ,is grasped at the movement in a single plane is provided by the use of a two-pronged staple 18 arranged parallel to'the edge of the marginal portion 12 of the bag 10. In Fig. 4, it is provided by the inward edge of the overlying portion 20 of the tab, and in Fig. by the similar edge of the overlying portion 24 of the tab. Such constraint to pivotal movement of the bag with respect to the receptacle is preferred but is not deemed essential to the desired manipulation, for the same result will be effectively obtained when the overlying margin 12 and tab are grasped between the thumb and finger of the user as shown in Fig. 1.

The bag normally lies within the dished receptacle 14, preferably with the bulky filled portion of the bag below the top edges of the receptacle 14, which gives the unit package a regular shape. The outer walls of the receptacle desirably slope outward to permit partial nesting between the several packages in a stack, which tends to prevent displacement of the package from the stack. A plurality of unit packages may be stacked in a market-size package in a regular and orderly arrangement, and the partial nesting between them will maintain them in good order in the package. There will be no strings to get tangled, and the individual unit package will be readily separable and removable from the package.

Figs. 1 and 2 illustrate .the use of my new package. For immersing the bag in a cup of liquid, the package attachment edge, as by its tab 16, between the thumb and finger of the user, and is held in a depending position. The relatively rigid receptacle 14 is swung downward and rearward to an inverted position, which leaves the bag hanging free. With the bag in this position relative to the receptacle, it can readily be lowered into the cup with the receptacle passing downward outside the cup. The package is then left hooked over the edge of the cup as is shown in Fig. 2, with the bag it) inside the cup and the receptacle 14 outside the cup, and with the tab 16 in an upstanding position above the cup. When the infusion has reached the desired strength, the package is again grasped by the tab and lifted clear of the cup, and the receptacle is swung forward and upward to carry the receptacle against the depending bag 10 and to cause the bag 10 to enter the I receptacle 14. Further pivotal movement brings the receptacle 14 with the wet bag therein to a horizontal or upright position. In that position it may be set on the table or on any horizontal surface, and the wet bag and any drainings therefrom will be wholly contained and confined Within the receptacle 14. The whole operation is a simple one-handed operation, and there is no need for the user to grasp the wet bag.

I claim as my invention:

1. An infusion package, comprising an infusion container having a flexible marginal portion, a dished receptacle of a size to receive the container, a handle-tab at one edge of the receptacle, the container being received in the receptacle with the flexible marginal portion thereof contiguous to the tabbed edge of the receptacle, and means aflixing the marginal portion and the tabbed edge together.

2. An infusion package, comprising an infusion container having a marginal portion, a dished receptacle of a size to receive the container, a projecting handletab at one edge of the receptacle, the container being received in the receptacle with a flexible marginal portion thereof overlying said tab, and means aifixing the marginal portion of the container to the tab.

3. An infusion package as defined in claim 2 in which the inner surface of the infusion container is absorbent.
