ARTICLE DISPENSER Filed Feb. 1, 1961 United States Patent 3,127,225 ARTICLE DISPENSER Willard J. Oehrlein, Milwaukee, Wis., assignor to Kimberly-Clark Corporation, Neenah, Wis., a corporation of Delaware Filed Feb. 1, 1%1, Ser. No. 86,351 9 Claims. ((11. 312--50) This invention relates to improvement in article dispensers.
A primary object of the invention is to provide an improved dispenser particularly adapted for the convenient storage and dispensing of paper towels and the like.
-A further object is to provide an improved low cost dispenser which may be fabricated of plastic materials by known production techniques.
Another object is to provide an attractive end type dispenser particularly adapted for use in barber shops and beauty parlors for the convenient dispensing of paper barber towels and the like.
Other adaptations and modifications of the invention will become readily apparent to persons skilled in the art upon examination of the drawings, description, and appended claims.
In the drawings:
FIG. 1 is a perspective view of a paper towel dispenser incorporating the invention principles,
FIG. 2 shows in perspective the dispenser of FIG. 1, with the front closure member thereof hinged open to permit access to the contents,
FIG. 3 is a front elevational view of the dispenser of FIGS. 1 and 2, with the front end closure member also shown hinged open, and broken off,
PEG. 4 is a fragmentary elevational view, in partial section, showing the front end closure member in locked position.
Referring to FIGS. 1 and 2, a dispenser incorporating the invention comprises generally a boxlike article storage container portion 11} of generally rectangular configuration, a hinged cover 12, and a hinged end closure member 14. The three components comprising the dispenser preferably are of a moldable plastic material and may be unitarily fabricated by known molding techniques. While the invention is not limited to a specific type of material, the physical properties of polypropylene render that material ideally suited for use for reasons stated below.
Container portion includes opposite side walls 16, 18, and a back wall (not shown) of equal height, the front wall 21) being of reduced height as best shown in FIGS. 2 and 3. Front wall is centrally provided with an upwardly open dispensing opening marginally defined by thickened portions which serve to reinforce the opening along the sides 22, 24 and along the bottom 26 thereof. The thickened front wall portion also adds to the attractiveness of the dispenser when closed, as shown in FIG. 1.
Cover 12 is hinged to the rear wall of container 10 in a known manner, and preferably by a thin strip-like hinge portion, preferably an integral portion intermediate container portion 10 and cover 12 as unitarily formed by a single molding operation. The front end of cover 12 terminates short of the container front wall 20, as best shown in FIGS. 2 and 4, with the cover lip 13 extending along the sides and back thereof. The front cover margin 30 is centrally provided with an extending locking fixture 32 transversely channeled at 34 to receive a hasp 36 integrally formed at a corresponding position of the top margin of closure member 14 for locking engagement therebetween, as shown in FIG. 4.
Closure member 14 is preferably formed as an integral extension of the bottom wall 36 of container 10 with a 3,127,225 Patented Mar. 31, 1964 thickness reducing groove 38 provided therein to extend along the base of the centrally thickened portion of front wall 20. Closure member 14, of generally T configuration, includes a top portion 40 of a width equal to that of cover 12 and of proper arcuate configuration to nest against the front end of container 10 and its cover 12 in a. manner to close the opening between front margin 31} of cover 12 and the top margin 44 of front wall 20 when member 14 is hinged from the open position of FIG. 2 to the closed position of FIG. 1. Leg portion 46 of member 14 is of a width simultaneously to close and overlap the front wall dispenser opening. Cover 12 is sufiiciently flexible to allow fixture 32 momentarily to be depressed by hasp 35 as member 14 is hinged into closed position and to then spring back into a locking position with hasp 36 held in channel 34.
As is apparent, the dispenser is constructed in a manner permitting fabrication by known high speed plastic molding techniques. For example, container 10, closure member 14, and cover 12 may unitarily be formed in a single mold of suitable design from polypropylene. Polypropylene offers the desirable feature that when grooved as at 38 a resulting flexible hinge line withstands fatigue during many thousands of hinging operations. If desired, container 1t) and closure member 14 may be formed in separate molding operations with member 14 thereafter suitably heat fused to container 10 along the base portion of front wall 20. Member 14 could, for example, be molded of polypropylene, with container 10 and cover 12 of a different plastic material, it being necessary of course that the container 10 be of a plastic to which polypropylene may be beat fused. Alternately, plastic materials which do not offer the same resistance to hinging as does polypropylene may be employed in fabricating the three major dispenser components, if such material allows fusion thereto of an insert of polypropylene which forms the hinge line along groove 38.
The invention is not, however, limited solely to the use of plastic materials, it being apparent that metal sheet stock, for example, may be employed to form the three major components by known stamping techniques, with member 14 hinged to container 10 either by an integral hinge area of reduced thickness or by a suitable mechanical hinge. The improved dispenser, in addition to permitting low cost fabrication, is ideally suited for barbershop use, since when positioned on a shelf it requires a minimum of space while offering the many advantages of front end dispensing plus an attractive appearance when either open or closed.
