FIG.- 34

Nov. 16, 1965 J. B. GRANT ETAL 3,217,954

DISPENSING CONTAINER FOR PACKAGE STRIPS Filed July 29, 1964 2 Sheets-Sheet 2 United States Patent 3,217,954 DISPENSING CQNTAINER FOR PACKAGE STRIPS John Barrett Grant, Greenwich, and Garry Thomas Higgins, Cos Cob, Conn, assignors to Richardson-Mental Ina, New York, N.Y., a corporation of Delaware Filed July 29, 1964, Ser. No. 385,846 9 Claims. (Cl. 225-32) This invention relates in general to a container for packaging, shipping and dispensing a package strip of the type that has commodity-containing compartments spaced longitudinally thereof and is severable between said compartments so that the compartments can be separated from the strip individually or in groups, as desired. In a preferred embodiment, the present invention relates to a onepiece homogeneously integral dispensing closure or top for such containers which can be economically molded or formed from plastic material.

Package strips of the type contemplated for use in this invention generally include two layers of flexible packaging material such as cellophane or metal foil, sealed together along their longitudinal edges and transversely to form compartments between the layers in which the commodity such as tablets, powders, liquids, pastes or the like is enclosed. Generally the strips or layers of packaging material are weakened in lines transverse of the strip, for example by scoring, to facilitate separation of the individual strip packages or compartments. The strip can be pulled longitudinally through the dispensing opening of the dispensing container and one or more compartments can be severed by forcing the weakened edge against a series of teeth or a cutting edge protruding upwardly of the dispensing container top.

An object of this invention is to provide a dispensing container for package strips which provides for easy and quick removal of the package strip, which holds the package to prevent automatic or accidental movement thereof out of or back into the container, and which is economical to manufacture and assemble.

Another object of this invention is to provide a homogeneously integral dispensing closure for such containers which can be easily and economically molded and subsequently attached to a container and which provides novel and reliable dispensing means for package strips.

Other objects, advantages and results of the invention will be brought out in the following description with the accompanying drawings in which identical numerals refer to identical parts and wherein:

FIG. 1 is a side elevation of a dispensing container in accordance with this invention with a coiled line showing the package strip and its direction of movement out of the dispenser;

FIG. 2 is a front elevation of the dispensing container of FIG. 1 showing the top teeth and folded or coiled prod uct strip carrying tablets;

FIG. 3 is a plan view of dispensing container of FIG. 1;

FIG. 4 is a longitudinal vertical section of the upper portion of the container taken in the plane of the line 4-4 of FIG. 3 showing a product strip being cut by the dispensing closure teeth;

FIG. 5 is a longitudinal vertical section of the container of FIG. 4 with a product protuberance of the package strip yieldingly held within the dispensing opening of the closure;

FIG. 6 is a partial transverse horizontal section taken in the plane of the line 6-6 of FIG. 4;

FIG. 7 is a partial transverse vertical section taken in the plane of the line 7-7 of FIG. 4.

Referring now to the drawings, container 10 is rectangular and comprises a bottom wall 11, side walls 12 and 3,217,954 Patented Nov. 16, 1965 l4, and end walls 16 and 18. A dispensing closure about the container top has side walls 22 and 24, end walls 26 and 28, a top panel 32, upwardly projecting teeth 34, a horizontal ledge 35 and resilient tongue 36. The dispensing closure is frictionally held in place by cooperation of its walls with those of the container. The dispensing closure is homogeneously integral and preferably molded from a plastic material such as high impact polystyrene, polypropylene, polyethylene and the like. The midsection of side walls 22 and 24 rise gradually above end wall 23 of the dispensing closure after which they become substantially horizontal and then dip toward wall 26. The top panel 32 joins side walls 22 and 24 over a portion of their length and extends from end wall 28 up to the dipping portion of the side walls toward end 26. The edges of top panel 32 toward end 26 have an outwardly flanged inverted U-shaped configuration. The smooth, substantially horizontal ledge 35 is inwardly of teeth 34. The ledge 35 is spaced vertically below and horizontally away from the opposed edges of panel 32 and defines a dispensing opening therebetween which is partially obstructed by tongue 36 projecting into a portion of the dispensing opening area. The base of tongue 36 is homogeneously integral with ledge 35. The tip of tongue 36 dips downwardly and has a smooth reinforcing bead about its edge. Tongue 36 is also spaced vertically below and horizontally away from the opposing edges of panel 32. From the plan views it can be seen that the edges of the tongue and ledge and the opposed edges of panel 32 have a horizontal component therebetween so that there is no overlapping of the opposed edges and the distance therebetween forms a dispensing slot 37 having the outline of an inverted outwardly flanged U or that of a bell with an outwardly flanged base. The distance between these opposed edges of the slot have both a vertical and a horizontal component. These opposed edges of the slot are substantially smooth. The horizontal component of the slot or dispensing space between the end of the tongue and the opposed edges of panel 32 is greater than that of the horizontal component of opposed edges at the side of the tongue or between the ledge 35 and panel 32. This facilitates dispensing of strips containing pills and the like which are equidistant the longitudinal edges of product strip 40. The tip of tongue 36 as well as the apex of the inverted U opening in panel 32 are equidistant from the side walls 22 and 24 of the closure. The dispensing closure is easily fitted over the top of the container.

A primary advantage of the construction of the dispensing closure of this invention is in the absence of any spaced overlap in the vertical plane of opposed edges of the dispensing opening 37. This construction permits molding of the dispensing closure by a simple two piece male and female mold and does not require a side action mold. This permits economical manufacture of the closure. Also, the positioning of the teeth upwardly at one end of the closure gives much the same advantages. Further, a larger number of mold cavities can be provided in a mold than would be the case if a side action mold was required.

Another primary advantage in the dispensing closure construction of this invention is that the product protuberances on the product strip are raised upwardly above the edges of panel 32 as they pass over the tongue 36 due to the resilience of the tongue. This prevents backward movement of the strip into the container since the product protuberances would abut against these edges.

Package strip 40 comprises a top membrane 46 and a bottom membrane 48 of flexible packaging material such as cellophane, rubber, hydrochloride or metal foil, sealed together along the longitudinal edges and transversely to form protruding compartments 42 between the membrane layers in which a commodity such as tablets 44 is enclosed.

The operation of the dispensing container of this invention probably will be understood from the foregoing, but it might be pointed out that the package strip will be first of all within the container as shown in the drawings. The leading end of the package strip will be pulled outwardly over tongue 36 and ledge 35 through slot 37 and over teeth 34. In passing through slot 37, the top and bottom sides of the strip are pressed against the ledge and tongue and opposing edges of the top panel. This is particularly the case when a strip protuberance passes through dispensing slot 37 and the tongue 36 is yieldingly flexed inwardly of the container top. As the strip protuberance moves out of the dispensing slot, it is raised upwardly due to the resilience of the tongue. A suflficient amount of friction is encountered by the strip as it passes through the dispensing slot or opening 37 to prevent automatic or accidental movement thereof out of the container. In addition to friction encountered by the product strip and its product protuberances in moving out of the container, movement of the strip back into the container is hindered due to the abutting relationship of the raised product protuberances with the edges of the top panel 32. The strip is cut by being forced against the teeth of the dispensing closure.

Having now described the invention in specific detail and exemplified the manner in which it may be carried into practice, it will be readily understood that any number of variations, applications, modifications, and extensions of the principles involved may be made without departing from its spirit and scope. Illustratively, the dispensing closure can be stamped out of sheet steel or other materials which can provide a resilient tongue which can be flexed downwardly as the product protuberance is squeezed between the tongue and the top panel 32 and then spring upwardly to its original position. The upward movement of the tongue raises the product protuberance slightly above the top panel 32.
