DRINKING STRAWS AND DISPENSER CAPABLE OF USE THEREFOR 2 Sheets-Sheet 2 Filed Dec. 5, 1965 INVENTORS WALTER C.LOVLL Mmn75 United States Patent Mass.

Filed Dec. 3, 19163,.Ser. No. 327,666 16. Qlaims. (Cl. 225-1).

The present invention relates to improvements in the merchandising of drinking straws or the like, and further to improvements in dispensers for drinking straws and elongated products in general.

One object of the invention is to reduce the amount of space required by drinking straws or like tubular products in storage and shipment, and further to permit the length of the drinking straw to be readily selected according to the needs of the user.

Another object of the invention is to provide an economieal dispenser construction. which is particularly applicable to the above ends and which further has, general utility for dispensing elongated products.

The invention, in one aspect, is characterized by a flat card to which is secured a plastic shell forming therewith a chamber in. which is, disposed a coil of elongated product. Advantageously, the coil of elongated product takes the form of a flattened or collapsed tubular drinking straw of indeterminate length. An outlet opening is provided, from this chamber through which the product may be drawn and then any length thereof so drawn may be severed for its intened use.

Other dispenser constructions may be employed where the elongated product is a drinking straw which is wound in a coil. with its walls collapsed, but in any event, a form ing section will preferably be provided tov facilitate the straws being returned from their collapsed condition to an open tubular form, as they are drawn from the dispenser.

Other advantageous features include the provision of means for restraining free movement of the elongated product so that the end which is drawn through the outlet opening may not be inadvertently drawn back into the product receiving chamber. Further, a cut-off knife may be provided on the dispenser at a point spaced from the outlet opening so that after a length of the product is severed, there will remain a free end of the product which may be readily gripped for drawing further length of product. Also, it is desirable to provide a protective chamber outside the outlet opening in which the end of the elongated product is disposed. The product may thus be completely protected from dirt and contamination during storage and shipment. The protective chamber is readily detachable from the dispenser so that the product can be drawn from the dispenser by the ultimate user.

In accordance with another aspect of the invention, the coil of elongated straws is wound from an originally straight extrusion of medium density polyethylene or like material having a high degree of elastic memory. The straws are originally of tubular circular cross section and are wound as a coil with the walls collapsed, thereby effecting great space saving economies, both from the coil form and from the fact that the walls of the straws are collapsed.

' vertising, instructions, etc. A hole 14 maybe provided.

The above and other related objects and. features of the invention, will be apparent from. a reading of the; following description of the disclosure found in the accompanying drawings and the novelty thereof pointed out in the appended claims.

In the drawings;

FIG. 3. is a. section, on an, enlarged scale, taken on line HI.III in. FIG.. 1';

FIG. 4 is a section, taken on line IV-.-IV in FIG. 3;

FIG..,5, is. a. section taken, on line V-.-V in FIG. 4.;

FIG. 6, is. a View. showing portions of thecard forming;

part of the dispenserremoved; and

FIG. 7 illustrates a modificationembodying an alternate feature of the invention.

The illustrated. embodiment of the; invention comprises a flat card 10. having a plastic shell 12 secured thereto to. form a product receiving chambergl}, The card, 10- may be economically formed: of paper board, cardboard-. or the like, and provides, a convenient. surface for printing adin the card. 10, sothat it can conveniently be hung on a pegboard display in a retail store.

. The shell 12,, isbestformed, by a vacuum. forming process and the selection of a suitable plastic. material: for such purposes is well. within the ability of those skilled in the art. Simply for the sake of illustration, it may be assumed. that the shell, 12 is formed of polystyrene. The shell 12 comprises an. outer wall; 1 6. and a continuous peripheral wall. 18, preferably having an outwardly" extending: flange 20- which is; heat sealed or otherwise secured to the cardv 10 to space the outer wall 16. from the card and, thereby form the product receiving chamber 11 in combination with the card 10. The surface of the card 10 may be plasticrcoated to. facilitate the heat sealing attachment of the shell thereto, again a practice well known to those skilled in the art.

The outline 'of the outer wall 16. may take many forms for decoratiye or ornamental purposes, but tends to be circular in order to. minimize the amount of material used. As illustrated, the outer wall. 16 is in the form of a grotesque human caricature having an enlarged head. The facial features of this caricature being molded into the outer wall 16.

An, inwardly extending projection 22 is. formed in the outer wall 10 and is preferably circular-in outline with its.

end surface. 24 heat sealed to the card 10- to. give greater rigidity to the dispenser. The. projection 22 also serves the function of a hub, as will later appear, and will be referred to as such. A cup-shaped, piece 26 may be telescoped into the projection 22 and sealed in place. The function of the piece 26 is primarily to enhance the ornamental appearance of the dispenser and may be formed of a distinctive color toaccentuate a particular feature of the caricature, in the present instance it represents. a nose.

As herein disclosed, the elongated product within the product receiving chamber 11 takes the form of a continuous length of drinking straw s of indeterminate length which is wound in a coil 21 about the hub 22. The coil 21 is preferably wound from a length of originally straight extruded medium density polyethylene or like material having a high degree of plastic memory. In winding the coil 21, the walls of the straw s are collapsed from their original circular cross section. The degree to which the walls of the straw are collapsed governs the amount of space which may be saved by the present invention. As illustrated, the walls of the straw are collapsed but not actually flattened. This is preferred since the amount of space which is required is substantially reduced, while at the same time the straws may be more readily returned to their fully opened circular cross section, as will later be more fully described.

One end of the straw, indicated at (e) extends from the coil 21, through an outlet opening 28, formed in the upper portion of the peripheral wall 18, and terminates within a protective chamber 32. The protective chamber 32 is formed by extensions 16s, 18s and 20s, respectively, of the outer wall 16, the peripheral wall 18, and the flange 20. The flange extensions 20s are heat sealed to the card 10 to seal this protective chamber. The portion of the card 10 forming in part this protective chamber is defined by score lines which may be either cut or perforated, or otherwise weakened. The extensions 16s and 18s are defined by a score line 37, and the flange extensions are defined by notches 39, so that the protective chamber may readily be removed to expose the outer end of the straw when it is desired to draw the straw from the product receiving chamber 11.

The card 10 advantageously is provided with

margins

41 and 43 at the left hand side and lower side thereof. The inner limits of these margins are defined by score lines 38 and respectively which enable removal of these margins after the dispenser has been purchased. With the margins removed, the dispenser itself is more compact and convenient for use. FIG. 6 illustrates the dispenser after these margins and the protective chamber 32 have been removed.

The outer end of the straw is positioned so that it may be grasped and any desired length of straw drawn through the outlet opening 28. The construction of the outlet opening is such as to facilitate quick return of the straw to its original circular cross section as it is drawn therethrough. In this connection it will be pointed out that from a technical standpoint the outlet opening will herein be considered as an outline created by the score line 37 and the portion of card 10 falling in the plane of that line. Inwardly of this outline there is a forming section 45 which is preferably of square cross section which serves the function of returning the straw from its collapsed condition to its original fully opened tubular form of circular cross section. It has been found that this square forming section, having a periphery equal to the circumference of the straw, is highly effective in opening the collapsed straw to a circular cross section. However, it is also possible to employ other shapes which would be effective on the straw to assist in transforming it from its flattened or collapsed condition to an opened tubular form.

At this point it will be noted that the straw s is preferably a thin-walled extrusion of medium density polyethylene or other material having equivalent characteristics, and particularly a high plastic memory. The extrusion is originally straight and of circular cross section and is allowed to set with this configuration. This extrusion is then wound into the coil 21 and placed in the described dispenser. As it is drawn through the forming section 45, it is forced from its flattened or collapsed condition to a square shape. The combined effect of the forming section 45 and the plastic memory of the straw material is such that the straw is readily opened to the desired circular cross section and also the straw is essentially straight. Within the broader teachings of this invention, it will be appreciated that straws or other tubular products having a non-circular cross section could also be used and ap propriate forming sections provided for opening such 4, straws or the like as they are drawn from a collapsed condition on a coil. penser is desired, a second projection 48 (FIG. 7) may If greater straightness of the straws pulled from the disextend inwardly from the outer wall 16 of a plastic shell 12'. The projection 48 may be secured to the card 10 in the same manner as the hub 22. The length of straw drawn from the coil 21 is trained about the projection 43 to bend the straw in a direction opposite to which it is Wound on the coil 21. As the straw is drawn from the coil and bent around the projection 48 before passing through the outlet opening 28, the reverse curl tends to minimize, if not fully eliminate, any curve in the length of straw drawn.

A further function of the constricted outlet 28 opening and forming section 45 is that of restraining free movement of the straw so that its end may not be inadvertently drawn into the product receiving chamber. Such restraining means could be separately provided and for the sake of designating such means, in the present case, it will be considered that the inner outline at 42 serves this function.

The card 10 is generally rectangular in outline and has a portion of its upper edge disposed on a bias. A cut-off blade 45 is secured parallel to this biased upper edge at a point spaced from the outlet opening 28. The cut-off blade 46 preferably has a serrated edge which eliminates the need of sharpening the blade when it is formed of a; relatively thin material in the order of .015". The described disposition of the knife facilitates severing of a desired length of straw in that the angular disposition of the blade tends to concentrate the pressure of a single point of the blade as the straw is pulled thereover to thus obtain an initial puncture of the straw material so that it may then be readily severed.

It will, of course, be apparent that the present dispenser may be used for other elongated products and by the same token the specific details of the dispenser construction are not necessarily required in obtaining the advantages of dispensing straws or like tubular products in coil form bearing in mind the advantages which are obtained from the reduction in space requirements in storage and shipment, as well as convenience in being able to readily obtain any length of straw desired. Thus, for example, it will be noted that the space requirements for a 20-foot coil of straw, assuming reasonable hub diameter and with thin-walled (.008") straws completely collapsed from their circular cross section, are approximately /5 of what is required as for 24 ten-inch straws packaged in a rectangular container.

Variations of the present invention will occur to those skilled in the art and the scope thereof is to be derived solely from the appended claims.
