United States Patent O 3,313,473 EISPENSING PACKAGE Lee Roy Witter-s, 1401 N. Main Ave., Sidney, Ohio 45365 Filed Apr. 2, 1965', Ser. No. 445,090 9 Ciarns. (Cl. 229-86) This invention relates to a dispensing package, and has particular adaptability to disposable packages, such as are utilized in dispensing individual servings of instant coffee or tea, or other powdered or liquid materials, although it is `within the purview of the instant invention to provide a similar package with resealable means so that the same can be employed more than once if desired, such as a tobacco pouch or the like.
A primary object of this invention is the provision of a unitary single or multiple use package provided with a pull-type lift tab, `which is adhesively secured to the package and serves as a seal, which tab, when opened, may serve as a pouring spout to pour the contents of the package directly into a cup or container without waste.
A further object of this invention is the provision of a package of this character which, `=by obviating the conventional pull string across the top of the package may be opened in a simple and expeditious manner without spilling the contents ofthe package.
Still another object of this invention is the provision of a package of this nature which may be opened with a minimum of diculty and effort.
A further object of this invention is the provision of a package of this nature provided with reusable adhesive sealing means, whereby the package may be employed for a multiplicity of servings before disposal.
A further object of this invention is the provision of a package of this nature which is sturdy and durable, which adequately protects the contents thereof, which may be manufactured simply and inexpensively, and which is reliable and eflicient in operation and which avoids tearing or mutilating the package during opening thereof.

Similar reference characters refer to similar parts throughout the several views of the -accompanying drawings.v
Having reference now to the accompanying drawings and more particularly to FIGURES l and 2, there is generally indicated at 20 one form of a package constructed in accordance with the instant invention. The package comprises a single sheet of material, any desired substance being utilized, but laminated aluminum foil having been found preferable, folded along a ybottom edge 19 thereby providing a top and bottom surface 21, 22 respectively. Surface or sheet 21 may be considered as the top of the package 20, and terminates in a straight edge 23, while surface 22 comprises a bottom sheet and is provided with a tab 24 extending across the entire width of edge 23 thereby conveniently providing a closure for package 20. Sheets 21 and 22, which are but extensions of the single piece of material folded along edge 19, are adapted to be sealed by any suitable adhesive 26 placed along the two side edges and bottom edge adjacent fold 19. A similar adhesive 28 is applied to upper sheet 21 between edges 28 of tab 24 as shown in FIG- URE l, a similar line of adhesive 29 extends between the inclined straight edges 2S at a point adjacent, but not including the extreme end 30 of the tab. Thus extreme end 30 of the tab 24 is left free and is bent upwardly as best shown in FIGURE 2. There is lthus provided a disposable package, of a convenient size which is easily held in the hand of a user for dispensing an individual serving of such material as instant coffee or instant tea. In the use and operation of the package upstanding end 30 of tabe 24 is grasped between the thumb and forenger, and by pulling thereon the adherence of adhesive disposed at 28 and 29 is released. The tab is then extended to the dotted line position of FIG- URE 2, and by pressing on the side edges of the package the tab may be concaved in much the same manner as FIGURE 16 to form a spout, by means of which the contents of the package may be readily poured into a cup or receptacle without waste thereof.
FIGURES 3 and 4 disclose a similar package generally indicated at 35 and comprised of a single sheet of material folded along lower edge 27 forming upper and lower sheets 36 and 37 marginally secured around side edges 38 to form outwardly extending flanges. In this form of the invention a closure tab 39 may form a separate piece which is adhesively secured as at 40 to lower sheet 37 and which is generally similar in coniiguration to tab 24 of the embodiment shown in FIGURES l and 2 with the following exceptions. Tab 39 has at the surface abutting package 35 an end 34 which is parallel to and extends along side edges 38 when tab 39 is in closed position. Tab 39 also has disposed on its outer surface a series of L-shaped reinforcing ribs 41 providing a stiffener in both the longitudinal and transverse directions. As shown in FIGURE 3 reinforcing ribs 41 do not extend to the center of tab 39 thus providing a substantially V-shaped spout when the edges 38 of the package are pressed together. Marginal adhesive 42 extends around the inside of tab 39 along end 34 to a point adjacent the extremity 43 thereof, extremity 43 being bent upwardly in a manner similar to that of the previously disclosed modification. The use and operation of this package is identical to that previously described, but it should be noted that adhesive along edge 34 provides a package which is particularly adapted to hold finely pulverized material and prevent it from escaping around the junction of tab 39 and upper sheet 36.
The modification shown in FIGURES and 6, and generally indicated at 45, is substantially identical to that shown in FIGURE 3, with the exception of the fact that reinforcing ribs 41 are omitted, and an additional interior tab 46 is provided adjacent the upper marginal edge or opening of package 45. Interior tab 46 may be conveniently provided by making upper surface 36a of package 45 somewhat longer than lower surface 37a in folding the edge thereof as shown in FIGURE 5. The provision of interior tab 46 aids in the retention of material inside package 45, and in this regard it has been found advantageous to provide a paraiiin seal between the surface of tab 46 and tab 39a. A tab 43a is provided for package 45 in much the same manner as tab 43 is provided for package 35, and pulling on tab 43a will release both the seal formed by marginal adhesive 42a and that formed by paraiiin secured tab 46. The use and operation of package 45 is identical to that of packages 20 and 35 previously described.
In FIGURES 7 and 8 there is shown a still further modification of a package construction generally indicated at 47 and including an auxiliary inner tab 46a of the same type as shown in FIGURE 5. Auxiliary inner tab 46a may be secured to closure tab 39h by paran, adhesive or the like, and is provided with an auxiliary strip 48 thereon. Aftr tab 43h has been raised should adhesive strip 46a adhere to tab 391'), identical to the previously described tab 39 except for the omission of the reinforcing ribs, auxiliary strip 4S may be grasped to release the further adhesive seal.
FIGURES 9 and l0 disclose a modified form of construction, wherein the package indicated generally at 50 is substantially identical to previous modifications, and includes a sealing tab 51 having marginal adhesive strips 52 and an upstanding tab 53. In this embodiment of the invention an additional strip of a reusable adhesive 54 is applied across the upper surface of package Sti so that when tab 51 is closed reusable adhesive 54 lies interiorly of the marginal adhesive sealing means S5. This package may be used for such commodities as candy, dry foods, or the like, wherein a larger package is desired, and wherein it is desirable that the package may be resealed after initial use. The use and operation of package 50 is substantially identical to that of packages 20, 35, 45 and 47 as previously described, however, the provision of reusable sealing means 54 enhances the possibility of reuse of package 5i).
FIGURE l1 discloses a still further modiiied form of package, generally indicated at 60, and including a tab 61 having marginal sealing means thereon similar to sealing means 52 of package 50, as well as a free tab 63 which protrudes upwardly as in the foregoing modifications. In this form of the invention an additional strip of adhesive 65 extends transversely across the body of the package, interior of the marginal sealing means indicated above, and extends diagonally upward as at 66 to the corners of package 60 as shown. This arrangement is particularly desirable in the case of semi-fluid materials, but may also be employed with solid materials such as dry salad dressing mix or the like wherein a relatively large package is employed. The use of the additional strip of adhesive diagonally extending from the corner of the package provides a receptacle which is peculiarly adept at retaining material therein without spillage at the corner thereof.
A still further modification is disclosed in FIGURES 12 to 14 inclusive, and is adapted to be utilized for powdered soups, powdered onions, vegetables or the like, wherein a relatively large quantity of material is eni` ployed for an individual serving. In this form of the invention reusable adhesive may or may not be employed, as shown in the species of the invention disclosed m HGURES 9, 10, and 11, depending on whether er not it is desired to reutilize the package, or dispose of all the contents at once. In this form of the invention package generally indicated at 70 is formed of a single sheet of material folded as at 69 to provide an upper and lower sheet 67, 68 respectively. As shown in FIGURE 13 the bottom of package 70 is folded inwardly as at 72 to form an accordion-like pleat, whereby the package may be expanded to hold a relatively large quantity of material. The marginal edges of package 70 are folded inwardly to form an internal iiange 71, which is adhesively sealed interiorly of package 70 and which provides another accordian-like pleat in much the same manner as lower fold 72. In this construction, an outer tab 73 is provided, beneath which and secured to upper surface 67 is a straight reusable adhesive strip 74 extending transversely across package 70. An upturned tip 75 is provided which may be grasped between the thumb and foreiinger rendering the use and operation of this embodiment identical with those previously described. An additional inner seal 76 may be provided to facilitate preservation of the retained contents whenv tab 73 is secured to upper surface 67 by an adhesive means in addition to lreusable strip 74.
FIGURES 18 to 2O inclusive disclose a modified form of construction, wherein the package indicated generally at 77 is similar to the form shown in FIGURES l to l1. The receptacle is formed by folding a single sheet 78 in order to provide one closed end 79 with adhesive 80 closing the marginal sides. A suitable adhesive 82 is secured transversely across the upper edge of package 77 and extends diagonally upwardly to the side edges thereof as shown. The tab 81 is provided which is of similar configuration to that previously described such that when tab 31 overlies the upper sheet of package 77 adhesive strip 82 falls interiorly of the upwardly extending tip portion 84, thus providing a means for convenient grasping. An additional sealing member or inner tab 83 is a paraffin or the like coated member for providing an additional inner seal. When initially assembled, inner tab 83 will bond or adhere to sheet 78 to provide a hermetically sealed package.
A further modification is shown in FIGURES 2l to 23 and is adapted to hold tobacco or other material in which the entire contents of the package are not used at one time. The receptacle shown generally at 85 is made of a single sheet of material 86 folded to provide a closed end 87 with side edges S8 being folded and secured by a suitable adhesive in any suitable manner. A tab 89 is provided with a suitable adhesive 90 secured transversely across upper sheet S6 and extending vertically upwardly to the corners of package 85. A strip of reusable adhensive 90 may be secured transversely across sheet 86 and provide a means of conveniently reusing package 85. An inner tab 99 is ixedly secured to tab 89 as shown in FIGURE 23 and extends downwardly to a point just above adhesive strip 90. When outer tab 89 -is closed, inner tab 99 provides an additional air seal in order to keep the contents of package 85 in a fresh condition.
FIGURES 24 to 26 inclusive disclosed a similar package generally indicated at 91 comprised of a single sheet of material 92 folded to provide a sealed end 93 with the side edges thereof adhesively bonded as at 94 in any suitable manner to provide an open top receptacle. As shown in FIGURE 26, a reusable adhesive strip 96 is provided with a tab 97 which acts as an upward extension of sheet 92. A tab 95 is reusably adhesively secured to sheet 92 by adhesive strip 96 which is exposed through a slot 98, the 4adhesive being carried interiority of the package, the adhesive strip being upturned at its ends to provide a substantially air tight seal. The use and operation is identical with those packages perviously described.
There is shown in FIGURE 27 a package indicated generally at 100 comprised of an upper and lower sheet 101, 102 and having a main tab 103. A convenient means of securing tab 103 to upper sheet 101 is shown in which a slot is formed of any configuration in sheet 101 and a strip of material 104 is fixedly secured in the cavity formed beneath sheets 101, 102 -along the later-al extent of the slot. Positioned in the slot in sheet 101 is a strip of adhesive 105 which makes a separable connection with tab 103 when the tab 103 is pressed thereagainst.
There is shown in FIGURE 28 another means of securing a tab 103 of a package 100 to an upper sheet 101 thereof. Fixedly secured to the outer surface of upper sheet 101 is a strip of material 106, which may be of any desired configuration, and on which is secured an adhensive strip 107 which may or may not be of the reusable variety.
In all of the species of the invention hereinbefore shown and described, the operation is essentially the same, in that there is herein provided a package which may be opened barely by lifting the end of a closure tab, which is adhesively sealed to the package, thus obviating the necessity of tear cords or the like. In certain modifications of the invention it will be seen that by the use of reusable adhesive the package may be opened and reclosed as desired until the contents thereof are exhausted.
It will also be seen that there is herein provided an improved disposable package which accomplishes all of the objects of this invention, and others, including many advantages of practical utility and commercial importance.
It has been found that many other modifications may be made in the inventive concept herein disclosed, among winch are constructing the body portion of a package out of two sheets of materials secured along three edges thereof rather than using a single sheet of material folded to form one edge. It has also been found that the adhesive strips securing the tab to the body portion may be placed on the tab rather than the body portion. As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiments herein shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
