12 Claims. (Cl. 150-48) This invention is in the field of containers such as clothes hampers or the like, preferably made entirely out of plastic by injection molding, although it is by no means limited in this respect.

A primary object of my invention is a plastic container, such as a clothes hamper or the like, having good air circulation to prevent clothes from mildewing.

Another object is a plastic clothes hamper having a hinged top with a simplified but efiective hinge.

- Another object is a clothes hamper, preferably a11- plastic, with a'pivoted top constructed to withstand large compressive loads.

1 2,873,782 Patented Feb. 17, 1 959 ice creasing in width so that the side wall between adjacent corner portions, such as the short wall 20, decreases in lateral width upwardly as shown in Figure 4.

The major or longer walls 18 are each provided with an intermediate somewhat centrally located ofi'set portion or wall 34 which is tapered upwardly increasing in width so that the major walls are divided into generally equal wall sections 36 that are also generally equal to and approximately the same size as the minor walls 20.

At each of the offset corner portions and also at the intermediate offset portion 34, I provide depressions 38 which are integral with the bottom wall 14 and offset portions. These depressions are shown as somewhat squareand projecting below the bottom wall 14 to function as feet or supports for the hamper. It should also be noticed that the offset walls 30 and 32 and the well rounded corner 28, joining the sections 24 and 26, flow jection at each corner to function as legs or supports and Another object is a rectangular all-plastic clothes hamper with integral reinforcing offset portions.

Another object is a rectangular clothes hamper which may be injection molded. Anotherobject is a rib structure for the top of an allplastic clothes hamper or the like providing substantial air circulation.

Another object is a new and improved hinge structure for a container.

Other objects will appear from time to time in the ensuing specification and drawings in which:

also a supporting leg generally in the middle of the major or longer Walls 18. 7

Both the inner and outer surfaces of the offset portions at the corners and intermediate the major walls taper upwardly increasing in width as shown in Figures 1 and 2, for example. i I provide an offset or flange 40 toward the top of the hamper. Above the flange the 'top edge of the hamper is rolled over outwardly at 42 providing, as shown in In the-drawings, the container is shown in the form I of a clothes hamper but there are certain features and characteristics that might be used in other structures. In any event, the hamper has a body 10 and a cover or top 12. The body or main container is closed at its lower end by an integral wall 14 and is open at its upper end as at 16. As shown, the body has a polygonal cross section with four sides in the form of a rectangle truncated upwardly or tapered so that the base is smaller than the top. The longer or major, side walls 18 join the shorter or minor walls 20 at corner sections or portions 22 which are-offset outwardly. The corner portions are integral with the sidewalls and taperedupwardly. As shown, each corner portion has generally perpendicular sections 24 and 26 joined by a smooth, well-rounded, integral turn 28, with offset walls 30 and 32 joining the adjacent side. walls. Each section 24- and 26 tapers upwardly in-' Figure 4, a smooth upper surface or rolled edge to support the top. I v

The top 12 has a turned over flange or skirt 44 which is constructed to closely oppose and fully overlie the rolled edge 42 on the hamper. The lower or inner surface of the top is provided with an integral rib construc tion as in Figure 5. As shown, this bracing or ribbing includes a marginal rib 46 which is somewhat parallel to the skirt 44, but uniformlyspaced from it, thereby providing a continuous downwardly opening channel or groove 48, which receives and conforms to-the turned over edge of the hamper. Within the rectangle or area defined by the marginal rib 46, I may provide any suitable ribbing. I have shown diagonal ribs 50 which extend from one corner to the other crossing generally at the center 52 and longitudinal and lateral ribs 54 and 56. I

may provide arcuate ribs 58 at each end and a circular 'rib 60 around the center merging with the marginal ribs 46 on each side 61. j The downwardly opening channel 48 extending around the side is spanned by a suitable number of lateral ribs which may be formed as extensions of the marginal ribs at the corners as at 62, as extensions of the main lateral ri-b in the center, as at 64, and with additional spanning ribs 66 at intermediate locations, as desired. In any event, these spanning ribs rest against the rolled over upper edge of the body or container to hold the channel in spaced relation to all points to the rolled over edge. Thus, the skirt of the top and the rolled over edge on all sides provide an air vent or open slot for the circulation of air to prevent the clothes in' the hamper, which are normally moist, from spoiling and mildewing.

Additionally, on the top I provide a cover or plate 68 which may be buttoned to the top by a plurality of downwardly projecting buttons 70 through suitable apertures 72.

were

vided with an outstanding wall 78 below the countersink. Side walls 80'on each side complete theeockefwith the wall of the body terminating at 82. The inner surfaces of the walls 80 are provided with concave, somewhat spherical portions 84 Opp sing each other.

A ball element 86 depends from the top and is disposed in the channel 48. As shown, the, ball is slotted at.88 to provide two somewhat spaced, flexiblelobes 90, each of which hasa somewhat spherical portion 92, back. to back. The opposed .or inner surfaces of the lobes have concave recesses 94 adapted to receive spherical projections 96 on a circular wedge element 98. The lobes are otherwise flexible and to insert the ball, the wedge is removed and the lobes compressed together andinserted in the socket. Thereafter, the wedge is forced between the lobes until the spherical projections 96 pop into the slots or recesses 94 providing a solid hinge. The top'may be'mounted on the body by havingthe top'in itsjr'aised position. 'The'lob'esare compressed and PQPPedfinfo the sockets. Thereafter, fromt'h'e 'ins idethe wedgesmay he slipped intothefslot 88' between the lobes. The use, operation and function ofrny ,inventionam as'follows: i ii I provide a preferably all-plastic clothes hamper, although many of the features are applicable to other devices. Irrespective, the clothes hamper has a top which is hinged preferably at two places. The lower surface of the top has a rib structure which in additionto reinforcing the top providing a structurally strong member, and additionally spaces the top at all points from the rolled over upper edge of the container, thereby .providing a continuous peripheral air gap giving good air circulation. I connect the top and bottom together by a hinge structure which includes a ball and socket. The rolled over edge of the body is preferably countersunk into a socket. The ribbing and skirt on the top provides a continuous downwardly opening channel and the ball elements depend fronibut' are confined in the channel. When the top is mounted, the channel conforms to and somewhat surrounds the rolled over 'upper edge [Of the body.

The ball element is slotted and divided into two lobes which are somewhat flexible and maybe compressed and popped into the socket. The'wedge element can be in- 'serted into the slot thereby providing a solid ball. i

' The top is provided'with a plate which is buttoned .into a suitable number of apertures for additional strength and decorative purposes.

The body has ofiset corner portions and intermediate offset portions in the major walls. Depressions in the form of supports or legs are formedas c'ontin u'ations of the oifset portions, andt'he'bottoni wall is'show'n as separate planes rising to a'common central platform 1 00.

Additionally, the hamper is well ventilated, structurally strong, but inexpensive "to make. Thet'op is reinforced and will withstand bending loads. The jsidewa11s6r the container are reinforced by the" ofiset portion's fo carry compressive loads caused'by articles being placedon the top. The ball and socket elements of the hinge are aligned so'that compressive loads merely tend to drive the ball element into the socket, rather than separating them. The hamper can be easily cleaned, will not rust or break and can be easily handled due to its light weight.

While I have shown and described the preferred form and suggested various modifications of my invention, it should be understood that suitable additional modifica tions exist which will be obvious. For example, while I have stated that the device is preferably all-plastic, it might be otherwise. Additionally, I have referredtof the invention as s clothes'hampen'bufmany important feat tures could be used in other devices. The tapers'of the body or container areimportant in injection moldingso that the device can be gotten out of the mold. The top and body are, of course, molded separately. It is im: portant that the ribbing in the top l e integral. The wedge 98 might be metal or plastic. With these and other changes in mind, I, therefore, wish that the invention be unrestricted except as by the appended claims.
