Lawrence Levinson BY 32. F lg. 4 MW ATTORNEYS United States Patent O 3,534,424 COLLAPSIBLE CONTAINER, DUSTPAN ASSEMBLY FOR SOLID CLEANING MATERIAL Lawrence Levinson, Newton Centre, Mass., assiguor to Control Packaging Corporation, Medford, Mass., a corporation of Massachusetts Filed July 15, 1968, Ser. No. 744,868

Int. Cl. A471 13/52 US. Cl. -105 12 Claims ABSTRACT OF THE DISCLOSURE A container, useful in packaging solid cleaning aids, which is convertible into a dustpan and reconvertible into a disposal container. The container is formed of triangular sidewalls and two main wall panels, each said wall panel extending between a pair of said sidewalls and each said wall panel being pivotally hinged one to the other at the smallest angle of said triangular sidewalls.

BACKGROUND OF THE INVENTION The rapid collection and removal of noxious spillage especially in public places such as schools, hospitals, and doctors offices is most desirable. This removal should be accomplished by means readily stored near the site of probable use, but should be accomplished by relatively simple manipulative steps. If so accomplished, any odor from the spillage will be contained in the smallest possible area for the shortest possible time. Thus any chainreaction often caused by such odors will be avoided.

Although there have been solid absorbents impregnated with deodorizers and suggested for use in such situations, there has been a need for a convenient dispensing and disposal means for such materials.

SUMMARY OF THE INVENTION Therefore it is an object of the invention to provide an article which is compact, easy-to-use and sufliciently versatile to serve as a package for a solid cleaning aid, a dustpan, and a disposal container.

Another object of the invention is to provide a disposable dustpan of simple construction and a process for forming such a dustpan.

Another object of the invention is to provide a box blank easily convertible into a disposable dustpan.

Other objects of the invention will be obvious to those skilled in the art on reading the instant specification.

These objects have been substantially achieved by providing a multipurpose container of triangular cross-section which container is adaptable for use as a disposable dustpan. This container is formed of a top wall and a bottom wall pivotally connected at an apex of the triangle. Each of the top wall and back wall is provided with triangular side walls and a rectangular back wall. In use as a dustpan the top wall and walls associated therewith form n angled support suitable for holding the bottom wall and walls associated therewith in an advantageous attitude for use as a dustpan. In the more advantageous embodiments of the invention, the rectangular backwall of the top wall includes a cut out to provide easier handling, and a flexible sheet is attached to the bottom wall to provide positive means for reducing the angle of contact between the floor being cleaned and the dustpan.

This novel apparatus has been found to be particularly useful in the removal and disposal of small-volume spillage. Among the uses are the cleaning-up of spillage such as might result from motion sickness in school buses, airplanes, automobiles, boats, and other confined locations where the usual cleaning aids and disposal means are unavailable. Moreover the article of the invention is con- 3,534,424 Patented Oct. 20, 1970 veniently used in doctors offices, hospitals, schools, theaters, stores, and other such public places as well as 1n the home and in laboratories.

ILLUSTRATIVE EMBODIMENT OF THE INVENTION FIG. 1 is a plan view of a box blank, an advantageous embodiment of the invention.

FIG. 2 is a plan view of a scraper, or brush, means useful with, and advantageously included with, the package assembly of the invention.

FIG. 3 is a view in elevation of the container in its closed position.

FIG. 4 is a plan view of the container in its open position.

FIG. 5 is a side view in elevation of the container in its closed position.

FIG. 6 is a rear view, in elevation, of the container in its closed position.

FIG. 7 is a perspective view of the blank of FIG. 1 arranged as a dustpan.

Referring to FIG. 1, it is seen that a box blank 12 formed of cardboard comprises a top major wall, or panel, 14 and a bottom major wall, or panel, 16 joined at a central scored hinge line 18. Along each lateral side of walls 14 and 16 at hinged score lines 19 are substantially triangular side walls 20 which meet at the terminals of line 18, each said wall 20- being divided by a scored hinge line 22 into a larger sidewall component 24 and a smaller sidewall component 26. The width of sidewall component 26 is approximately the same as the height along its dimension a of backwalls 2-8 and 30. At the outer extremities of walls 14 and 16, and attached thereto by scored hinge lines 27, are backwall members 28 and 30* respectively. Each of backwalls 28 and 30 have side tabs 32 at either end thereof. Side tabs 32 are suitably truncated triangular shape and are attached to backwalls 28 and 30 on hinged score lines 33. Backwall member 28 has a cut out handhold '34 and a closure means 35 i.e. tab 36. Backwall member 30 comprises a receiving means 38 for tab 36, said receiving means comprising slots 39.

A scraper, or brush, means 42 comprising a piece of cardboard 43 of such size that it will fit on top wall 16 is seen in FIG. 2. Scraper 42 has a cutout 44 to facilitate removing the same from flatwise contact on panel 14 or 16 and to serve as a hand grip.

Referring to FIG. 4 a container 45 is seen as assembled from blank 12 of FIG. 1: an additional feature has been added to FIG. 4 in that a flexible plastic sheet 47 is adhesively connected to bottom wall 16 and extends therefrom so that it overlaps part of top wall 14. This sheet 47 is advantageously treated on the bottom side thereof with a non-slip additive such as is known to the packaging art. Also shown in FIG. 4 is a partial view of a plastic bag 48 containing absorbent granules 50, an item for which the container of the invention is a particular suitable package for reasons described hereinbelow. In FIG. 4, backwall 28 is shown in collapsed position, that is with backwall 28 and sidewalls 20 folded inwardly to contact top wall 14. This folding is made possible by score lines 22 which provide means for bending larger sidewall component 24 inwardly, whereupon backwall 28 can fold directly down over the smaller sidewall component 26 and over end tabs 32. This folding capability makes it possible to store finished boxes in a minimum of space.

FIG. 7 shows container 45 emptied of its contents and with that half of container 45 which comprises bottom wall 16 turned through an angle of 270 on fold line 18 and resting on the outside of top wall 14, thereby forming a suitable dustpan receiver 49 with top wall 14, back wall 28, and the triangular sidewall 20 associated therewith forming an angled support 51 for receiver 49.

In forming container 45 from blank 12, the blank is folded along score lines 18, 19, and 27. End tabs 32 are inserted under smaller sidewall components 26 and may be fastened thereto with staples, adhesives, or any other fastening means. A scraper means 42 is inserted into container 45. Also inserted into container 45 is a bag containing a quantity of particulate absorbent which may be formed of diatomaceous earth, silica, or the like and which is advantageously treated with an effective quantity of deodorant such as di-isobutylphenoxyethoxy ethyl dimethyl benzyl ammonium chloride or the like.

In use, container 45 is a convenient dispenser, dustpan and disposal unit. On opening container 45 and bending it ito the dustpan position shown in FIG. 7, granules from plastic bag 48 are emptied into dustpan 49 and spread over the spillage by hand. Scraper 42 is then used to push the entire mass of spillage plus absorbent granules back into the dustpan. Once the mass is returned to the dustpan, it is closed, fastened and thereby packaged for convenient disposal.

Although the container of the invention may be formed of any suitable material of construction, paperboard or plastic sheeting is preferred. When plastic sheeting is used, relatively thin wall paths can take the place of the scored hinge lines use for paperboard. When paperboard is used, it is most advantageous that it be selected from stock which is treated so as to be resistant to wetting on the outside surface of the container. On the contrary, it is most advantageous for the inside surface of the container to be easily wetted so that droplets of waste which may not be absorbed on the solid material will be absorbed on the inner surface of the carton and not be susceptible to spilling.
