DUST-PAN Patented Nov. 16, 1948 NITED STATES PATENT OFFICE DUSTPAN 'William E. Coats; Los Angeles, Calif.
Application October 11, 1946, Serial No.. 702,697
v'pain can be formed.
-It is an object of the invention to provide a scored blank, which may be made of cardboard or other suitable materials, to form a dust pan, scoop, or the like.
A further object is to provide a scored blank for forming a dust pan or the like which is of such inexpensive construction that it can be discarded after one or two uses.
A further object is to provide a scored blank for forming an inexpensive dust pan or the like which is well adapted for advertising purposes, the cost of the device being so small that it can be given away as a souvenir bearing advertising matter and the like.
These and other objects are attained by the novel construction and arrangement of parts hereinafter described and illustrated by the accompanying drawings, forming a part hereof, and in which:
Fig. 1 is a perspective view of a dust pan formed in accordance with the invention.
Fig. 2 is a sectional View of the dust pan.
Fig. 3 is a plan view of a blank for forming the dust pan.
Referring to the drawings, in Fig. 3 is shown a blank from which the dust pan is formed. This blank comprises a main body I, trapezoidal in shape. Connected to the main body by scored lines 2 are side aps 3, trapezoid'al in shape, the aps 3 having connected thereto by scored line 4 a section 5, rectangular in shape, and connected to the section 5 by scored line 6 is a second section 'I. Section 5 has a slit 8 and section 'l has two parallel slots 9. Attached to the main body I and separated by scored line 9 are triangular tabs I0 adapted to enter the slits 8.
Attached to the body I and dened by scored line II is a back piece I2, substantially of trapezoidal shape, which is separated by scored line I3 from a rectangular handle section I5. The back piece I2 is provided with a pair of slots I4 adapted to coincide with the slots B. Scored lines I6 connect the section I5 to trapezoidal side pieces I1, the latter having connected thereto by scored lines I8 the flaps I9. Connected to aps I9 by scored lines 20 are tongues 2|, adapted to pass through the slots 8 and I4. The aps I9 are provided with inclined slits 22 for holding the flaps together.
To form the dust pan, the blank is laid on a table face down, and the handle is formed by folding along the scored lines I6 and I8, the flaps I9 locked together by means of the slits 22 to provide a double thickness on the underside of the handle. The blank is turned over, and the tabs I9 and side flaps 3 bent upwardly, the tabs being pushed through the slits 8. The sections 'l are then folded along scored lines 6 to bring the slots 8 to a position to coincide with slots I4 in the back piece I2. The tongues 2l are then folded under to enter the lowermost slots 8 and I4 and up and back through the upper slots 8 and I4 (see Fig. 2), the handle section I5 having previously been folded back on scored line I3. The dust pan now has the shape shown in Fig. 1.
The upper edges of the back piece are preferably inclined as shown at 23, which facilitates folding and the forming of the pan, the supporting sections 'I for the back piece aiTording a full capacity of the pan, the sections 'I being of uniform height with the sections 5.
A dust pan of the type described formed from cardboard or similar material is able to pick up dust more electively than the common type of metal pans, as the card board body has a front edge which can be readily forced flat with the floor by pressure, while this is not possible with a metal pan having a dent or bend in its forward edge.
The blanks can be cheaply cut in large quantities, and shipped flat, the forming of the pans being accomplished at leisure by the distributor or by the ultimate user of the pan. The blank can bear advertising matter, and can be used as a calendar, or the like, providing an attractive and useful souvenir.
The above description is to be considered as illustrative and not limitative of the invention of which modifications can be made without departing from the spirit and scope of the invention as set forth in the appended claim.
The invention having been described, what is described is:
In a blank for forming a scoop comprising a single sheet of material having a main body section of polygonal outline formed by a top and a bottom parallel sides and end sides connecting said top and bottom sides, each said end side being formed by a rst straight part joined to the bottom side and a second straight part joined to the top side, said rst and second parts eX- tending towards and joining each other and forming an obtuse angle with each other, triangular sections integral with and hinged to said main body section at said second straight parts, respectively, of said main body section whereby each said triangular section is foldable toward said main body section, a back section having a top side and a bottom side, said back section being integral with said main body section and hinged thereto at the top side thereof whereby the back section is foldable toward said main body section, said back section having parallel to the top side thereof a pair of parallel slots, said back piece having end sides connecting the top and bottom sides thereof, each said side being formed by a third straight part joined to the bottom side and a fourth straight part joined to the top side, said third and fourth parts extending towards each other and forming an obtuse angle with each other, an elongated side section integral With said main section and hinged thereto at each of said first straight parts, each said elongated side section having a side'flap portion, a side corner portion and a back flap portion With the boundary lines between said portions being scored, the lengths of said side flap por tion and side corner portion being substantially equal to the respective lengths of said iirst part and said second part, each said side corner portion having a slit and being adapted to be folded against said triangular section whereby the apex 4 thereof may be pushed through said slit, said back flap portion having a pair of parallel slots adapted to be placed in register with the back section slots, a substantially rectangular handle section integral with and hinged to said back piece, side sections extending from and hinged to said handle section along the length thereof, and flap sections extending from said side sections and extending lengthwise beyond the same, each said flap sections terminating in a pair of tongue portions With the boundary lines between said tongue portions and the remainder of said flap section being scored, said tongues being adapted to be threaded through the registered slots for holding the sections in assembled scoop form.
