United States Patent 3,388,836 SHAKER-TYIPE BISPENSING PACKAGE Robert E. fitto, 5420 Briilwoori Lane, Cincinnati, (Brio 45243, and Herbert C. Brinkman, .Ir., Cincinnati, Ohio; saiai Brinkman assignor io said fitto Fieri Nov. 10, 1966, Ser. No. 593,577 6 Ciaims. ((11. 222-107) ABSTRACT @F TIIE BISCLOSURE This invention relates to -unt serving packages and is particularly directed to a nvel shaker-type package for dispensing granuiar or powdered eondiments, such as salt, pepper and the like.

In the past, several different types of disposable packages have been proposed for dispensing powdered or granu1ar condiments, such as sa1t and pepper. One highly desirable fezzture of such type of package is that it should produce a shaker or sprinkler eiect by means of which the condiments can be distributed over food. Previous efiords to provide a package of this type have resulted in pieateci or fluted packages or packages inciuding a number of spaced sealed areas eiective to define one or more spout-Iike openings. These packages have ali been subject to one or more objectionable defects. Por exarnple, some of these packages do not dispense the condiment in a dispersed strearn, but rather cause it to be poured in a. concentrated area, resuiting in -objectionable accumu- 1ation of seasoning. Others have been relatively bulky or expensive to manufacture.

The principal object of the present invention is to provide a new and improved shaker-type package which is not subject to these sbortcornings and has substantial advantages over any of the packages previously proposed.

More particularly, one important object of the presentinvention is to provide a sprinkler-type package baving an improved dispensing action by means of which condiments can be more uniformiy spread over food Without objectionable accumulations.

Another object of the present invention is to provide a flat package without flutes or the like. One advantage of such a package is that it is extrernely compact. Moreover, the sides of such a package can be printed With various types of advertising which can easily be read by the user.

A still further o'oject of the present invention is to provide a package which is extrerneiy economical to produce and which can be fabricated upon high speed packaging equiprnent.

More specifically, a package constructed in accordance with the present invention is formed from lightweight, fiexible paper. The periphery of the package is sealed and the opposing flat walls of the package are also joined to- -gether in interior areas spaced from one edge. The package is further provided With a perforated line consisting of spaced s1its extending parallel to the package edge in the area between the seaied edge and the interior sealed areas. The sealed areas and sealed edge portion of the package cooperate to hold the walis together in this area so that the slits do not open and the package contents do not leak.

The package is opened by tearing along the slits to rexnove an edge strip of the package. Even after the stnp has been removed, however, the two opposing wall portrons adjacent the tear 1ine are heid closeiy together by the interior sealed areas of the package and aiso, in many cases, by the interlocking of fibers along the torn edges. As a result, when the package is inverted and shaken, the material escapes slowly through the very narro w constructed slit-Iike space between the sheets. In practrcze, condirnents are distrbuted in substantially the same uniform manner as With conventional salt and pepper shakers.

It is another object of the present invention to provide a package which, when opened by even the most casual user, is torn in a manner to provide this optimum sprinking action. More particularly, in the preferred form of package of the present invention the two end siits respectively extend through the opposite side edges of the package. Consequentiy, when a person starts to pu1l the tear strip from either side, the package automatically starts to tear and continues to tear along the line of slits. The pouring opening is thus maintained in close proximity to the interior sealed areas which hold the Wails1 together restricting the escape of the packaged materra These and other objects and advantages of the present nvention Will be more readily apparent from the followmg detaled description of the drawings iliustrating a preferred embodiment of the invention.

In the drawings:

FIGURE 2 is a cross sectional view taken along line 2 2 of FIGURE 1.

FIGURE 3 is an elevational view similar to FIGURE 1 with a portion of the package being broken away to show details of constructon.

FIGURE 4 s a partiai elevational view of a package being opened.

FIGURE 5 is an elevational view showing a package With its top removed.

FIGURE 6 is a greatly enlarged, side elevatioual view of the package With its top removed.

The overall construction of one preferred form of package 1 embodying the present invention is best shown in FIGURES 1 and 3. As there shown, the package is of gcnerally rectangular outline configuration and is formed of a single sheet of folded, polyethylene coated, paper stock. One preferred paper is a paper which Weighs twentyone pounds per ream and which is coated on one side With polyethylene in the amount of five pounds per ream. The package is formed by overfoiding the sheet along a Iongitudinal edge 11 to forrn two opposing side walis. The remaining three edges of the package, i.e. top edge 12, side edge 13 and bottom edge 14, are closed by beat sealing the opposed polyethylene surfaces along a band of appreciable Width; for example, one-fourth of an inch.

The upper edge of the package is also provided With two spaced interior sealed areas 15 and 16. In one preferred package, these interior sealed areas are forrned by beat seaiing the opposed polye-thylene surfaces of the paper by means of pins one-sixteenth of an inch in diameter. The sealed areas 15 and 16 are preferably equally spaced from one another and from the fold line 11 and the inner edge 17 of edge sea1 13.

The present package further includes a line of perforations 18 which extends across the upper portico of the package parallel to the upper edge 12 intermediate the sealed areas 15 and 16 and the inner edge 20 of sealed strip portion 12. These perforations or slits are preferably formed by sharp, linear perforating knives. In one preferred package, the slits 21 are one-eighth of an inch long and the uncut Webs 22 between theslits are of a lesser length; for example, one-sixteenth of an inch. As best shown in FIGURES 3, 4 and 6, one slit 21 extends through fold line 11 on the right-hand edge of the package and a second slit 21 extends through the edge 13 on the left-hand edge of the package. This greatly facilitates tearng strip 23 from the upper edge of the packageto convert it to a dispenser in the manner shown in FIG- URE 4.

The complete package, as shown in FIGURES 1, 2 and 3, is adapted to be filled With any particulate material 24, especially a condiment, such as salt, pepper, sugar or the like. Even after the package is filled, opposing walls 25 and 26 of the package retain a substantially flat configu ration, it being understood that the thickness of the package is sornewhat exaggerated in FIGURE 2 for the purpose of illustration. Thus, these side wallscan be printed and the advertisernent, or the like, readily read by the user.

It Will also be noted that in the area of perforate line 18, the side walls 25 and 26 of the package are disposed closely adjacent one another and are practically in facial contact. The side walls are held together below the line of perforations 18 by interior sealed ateas 15 and 16 and above the line of perforations by sealed edge band along the top of the package. Thus, there is no tendency of the side walls to bulge in the areas of perforations 18 and no appreciable amount of material gathers between the side walls near the slits. The slits 21 rernain closed and substantially imperivous to the escape of the package contents. As a result, the present packages can be shipped and stored in a filled condition with practically no leakage of the contents.

In use, the user grasps the package and begins to tear the uppermost strip 23 beginning With the slit extending through one of the side edges 11 Or 13 of the package. These end slits insure that the strip tears along the line of perforations 18 shown in FIGURES 4 and 6. When the strip has been completely torn, it is discarded and the package is ready to be used as a dispenser. At this time, the two side Walls 25 and 26 of the package in the area of the line of perforations 18 still remain in substantial facial contact with one another, being held together by the interior sealed areas 15 and 16 Which are still intact. There is only a very narrow discharge slit between the opposed walls. Moreover, in some cases the irregularly s,sss,sss

torn fibers 27 in the areas between slits 21 on one side wall interlock With adjacent fibers on the other side wall to further hold the opposing side walls of the package togther and to restrict the discharge opening novv formed along the line of perforations 18.

As a result, when the package user inverts the package 10 and shakes it, the condiments are slowly discharged in somewhat of a curtain elfect, as shown in FIG- URE 5, in which they are distributed in a relatively uniforrn manner over the food to which they are being applied. As an example of the eiectiveness of the shaker feature of the present package, one package selected at random required well over one hundred shakes to discharge the two hundred and fifty milligrarns of pepper contained in the package. The pepper was quite evenly distributed over the area to which it Was applied.

From the above disclosure of: the general principles of the present invention and the foregoing description of a preferred embodiment, those skilled in the art Will reaclily comprehend various modifications to which the invention is susceptible. Accordingly, Wc desire to be limited only by the scope of the following claims.
