DISPOSABLE FOAM PLASTIC CUP DISPENSER Filed April 15, 1964 INVENTOR THOMAS P. Mc GLYNN ATTORNEYS United States Patent.

3,261,500 DISPUSABLE FOAM PLASTIC CUP DISPENSER Thomas P. McGlynn, Short Hills, N.J., assignor to Continental Can Company, Inc., New York, N.Y., a corporation of New York Filed Apr. 15, 1964, Ser. No. 359,851 6 Claims. (Cl. 221-63) This invention relates to a novel disposable foam plastic cup dispenser constructed from a single integral sheet of formed foam material and folded along a longitudinal fold line to hold a plurality of stacked paper cups in a dispensing position and is particularly adapted to be discarded upon the dispensing of the stack of cups.

An object of this invention is to provide a novel disposable cup dispenser which doubles as a shelf package containing a plurality of cups in nested stacked relationship whereby a consumer can purchase the combined dispenser and stacked cups as a unit and upon dispensing of the last cup, dispose of the cup dispenser.

Another object of this invention is to provide a novel disposable cup dispenser which includes a pair of generally U-shaped body portions in opposed face-to-face relationship, the body portions being formed from a single integral sheet of molded plastic material and being folded along a single longitudinal fold line, longitudinal edges of the body portions being secured together to define a generally tubular dispensing body of the dispenser, a bottom end portion of the body being opened to define a cup-dispensing opening, and a plurality of inwardly directed cup-retaining projections adjacent the opening to maintain a plurality of stacked cups in the dispenser yet permit the dispensing of a lowermost one of the cups.

A further object of this invention is to provide a novel disposable cup dispenser of the type immediately abovedescribed in which one of the body portions includes a generally flat planar panel, pressure sensitive adhesive being applied to the planar panel, and a removable protective strip overlying the adhesive whereupon removal of the strip, the dispenser can be secured to a generally vertical supporting surface.

A further object of this invention is to provide a novel disposable cup dispenser of the type heretofore described in which each of the body portions includes a partial closure for sealing an upper end portion of the body along a generally transverse edge portion while the body portions are secured to each other opposite the longitudinal fold line along contacting longitudinal edge portions.

A further object of this invention is to provide a novel method of packaging a plurality of cups in a disposable dispenser of the type including at least a pair of generally U-shaped bodies joined along a longitudinal fold line, the bodies having partial closures at one end and cup-retaining projections at an opposite end, comprising the steps of at least nesting a plurality of cups having peripheral lips in a stack, placing the stack of nested cups in one of the U-shaped bodies with the lip of an outermost cup adjacent the cup-retaining projections, folding the bodies relative to each other about the longitudinal fold line to bring the bodies into opposed face-to-face relationship and defining therebetween a cup-receiving chamber, and securing contacting edge portions of the bodies to each other.

With the above, and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawing.

In the drawing:

FIGURE 1 is a top perspective view of a novel cup Patented July 19, 1966 dispenser of this invention, and illustrates in phantom outline, a plurality of stacked cups positioned in one of a pair of body portions of the dispenser prior to closing the dispenser.

FIGURE 2 is a top perspective view of the disposable cup dispenser of FIGURE 1, and illustrates the dispenser after the body portions have been folded relative to each other along a longitudinal fold line.

FIGURE 3 is a top perspective view of the dispenser of FIGURE 2, and illustrates a removable protective strip covering an adhesive coated panel of the dispenser.

FIGURE 4 is an enlarged transverse sectional view taken along line 44 of FIGURE 3, and illustrates the relationship between a plurality of inwardly directed cupretaining projections and the stack of cups in the dispenser.

FIGURE 5 is a longitudinal sectional view taken along line 55 of FIGURE 4, and more clearly illustrates the relationship between the cup-retaining projections and a lowermost one of the plurality of stacked cups.

Referring to the drawing in particular, a novel disposable cup dispenser constructed in accordance with this invention is generally designated by the reference numeral 10. The dispenser 10 is preferably constructed from a single flat sheet of foam plastic material, such as polystyrene foam, which is formed or molded in a conventional manner into first and second substantially

identical body portions

11 and 12 joined together along an integral longitudinal fold line 13 (FIGURE 4).

Each of the

body portions

11 and 12 includes three substantially identical longitudinal body panels 14 through 16 which are arranged in a generally U-shaped configuration, as viewed in FIGURE 1 of the drawing. The longitudinal panels 14 through 16 terminate in respective triangular panels 17 through 19 at a first end portion (unnumbered) of each of the

bodies

11 and 12 to define a partial closure 20 at an upper end portion of each of the

bodies

11 and 12, as is best illustrated in FIGURE 3 of the drawing. An identical radially inwardly directed cup-retaining projection 21 having a rounded shoulder 22 is integrally formed in the panels 14 through 16 of each of the

bodies

11 and 12 at a second or bottom end portion (unnumbered).

The panels 16 of the

dispenser bodies

11 and 12 each terminates in an identical longitudinal edge portion 23 while the

panels

17 and 19 of the partial closures 20 each terminates at a generally transverse edge portion 24 of each of the

bodies

11 and 12.

Each of the panels 14 through 16 is relatively flat and planar and a pressure sensitive adhesive 25 (FIGURES 3 and 4) is applied to the panel 15 of the body portion 11 to permit the dispenser 10 to be readily and effectively secured to a generally planar supporting surface, such as a wall, when in use. A removable protective strip of material 26 (FIGURES 3 and 4) overlies the pressure sensitive adhesive 25 but can be readily removed therefrom, as shown in FIGURE 3, when it is desired to expose the adhesive 25 and secure the disposable cup dispenser 10 to a supporting surface.

With the cup dispenser 10 in the fully open position thereof illustrated in FIGURE 1 of the drawing, aplurality of paper drinking cups P having lips or curls L are nested to form a stack S which is inserted in either of the

body portions

11 or 12, the stack S being illustrated in the U-shaped body portion 12 of the dispenser 10 in FIGURE 1. The lip L of an outermost or lowermost of the cups P forming the stack S rests upon the rounded shoulders 22 of the cup-retaining projections 21 of the body portion 12. The body portion 11 is folded relative to the body portion 12 about the longitudinal fold line 13 until the

body portions

11 and 12 are in opposed face-to-face relationship (FIGURE 4) and the longitudinal edge portions 23 as well as the transverse edge portions 24 are in contact. The longitudinal edge portions 23 and the transverse edge portions 24 are preferably secured together by a conventional heat sealing operation adajacent the

panels

16, 17 and 19. In lieu of such a heat sealing operation, the

edge portions

23 and 24 of either of the

body portions

11 and 12 can be provided with an adhesive A for securing the

body portions

11 and 12 in face-to-face opposed relationship.

After the stack of paper cups S have been positioned in the dispenser 10 and the

body portions

11 and 12 thereof have been secured together, the longitudinal edge portions 23 and the transverse edge portions 24 are suitably trimmed in a conventional manner, as is illustrated in FIGURES 3 and 4 of the drawings. In the final form of the dispenser 10 illustrated in FIGURES 3 through of the drawings, the panels 14 through 16 define a generally hexagonally shaped cup chamber C (FIGURE 4) opening outwardly through a bottom end portion (unnumbered) of a dispensing throat T (FIGURE 5).

The dispenser with the stack of cups S retained therein by the cup-retaining projections 22 is then preferably provided with an overwrap (not shown) which prevents contamination of the cups P. The dispenser 10, the cups P and the overwrap form a package for the cups P which is purchased by a consumer. The overwrap is removed and after the removal of the protective strip 26 (FIGURE 3) the dispenser 10 can be secured to a supporting surface by the pressure sensitive adhesive 25.

The cups P are dispensed in a singular fashion through the throat T (FIGURE 5) of the dispenser 10 in a known manner with the shoulders 22 of the radially inwardly directed cup-retaining projections 21 preventing more than a single cup from being dispensed at one time in a well known manner. After the last of the cups P has been removed from the dispenser 10, the dispenser 10 is merely discarded and replaced with a completely new filled dispenser.

Though the dispenser It has been described as being constructed from a single piece of foam plastic material, it is also considered within the scope of this invention to form the dispenser 10 from two separate body portions, similar to the

portions

11 and 12 and either adhesively or heat seal the same together along two longitudinal edge portions in lieu of the longitudinal fold line 13.

The dispenser formed from two separate body portions just described would be filled in a manner similar to that heretofore described in the consideration of the cup dispenser 1%. That is, a plurality of paper drinking cups P having lips or curls L are nested to form a stack S which is inserted in either of the separate body portions of the dispenser. The unfilled body portion is then positioned atop the filled body portion and the body portions are then preferably heat sealed together along three sides of the dispenser corresponding to the

edge portions

23, 24 and the fold line 13 of the cup dispenser 10. Adhesive, rather than heat sealing may be applied to the three sides of the dispenser prior to overlying the body portions relative to each other or thereafter.

From the foregoing, it will be seen that novel and advantageous provision has been made for carrying out 'the desired end. However, attention is again directed to the fact that additional variations may be made in this invention without departing from the spirit and scope of this invention.
