'Hassler, Glenview, 111., assignor to Morton Salt Company, Chicago, III., a corporation of Illinois ' 1 Filed May 20, 19-51, Ser.No. 660,159 ~ 1 Claim}: (c1. 222-556) ' tainer end surface 11 in spaced relation with respect‘to said enlarged aperture. 7 _ The pouring spout 12, which is of conventional ‘con struction, is pivotally mounted on the surface 11 and is adapted, whenin the position shown in Figs. 1 and 2, to overlie and close o? aperture 12a. The aperture 12a and pouring spout 12 are provided to enable 'a large ‘amount of material disposed within the'container to be poured This invention relates to a closure construction and, 1. “ 15 directly from the container through aperture 12a. The perforations 14, on the other hand, are provided to enable‘ the material within the container to be sifted therefrom upon the container being disposed in an inverted position, In containers of this type, it is most desirable to close the pouring spout 12 in a closed position, and the closure off the perforations formed in one surface of the con tainer, when the latter is not in use, so as to prevent 'ac 20 13 in the position shown in Fig. 2. The perforations 14 are arranged, in this instance, in relatively close proximity cidental discharge of the contents of the container or to with respect to one another and de?ne a triangular pat prevent moisture or foreign matter from ?nding its way tern. It is to be understood, of course, that the arrange into the interior of the container. ment of the perforations may be varied from that shown, Various closures of this particular type have hereto fore been proposed, which are ineffective or undesirable 25 without departing from the scope of this invention. Formed in container surface 11, in this instance, in ad for one or more reasons. For example, such prior closures more particularly, to a closure for a sifter-type ofcon tainer, such as a salt box or the like. ‘ ' ‘ ~ ' " dition to aperture 12a and perforations 14, is a slit ar are oftentimes of complex construction and have a tend rangement comprising a pair of slits 15 which are dis ency to be adversely a?ected or rendered inoperative by posed in relatively spaced relation with respect to one an the material being dispensed from the container. In ad dition, such prior closures frequently are not provided 30 other and with respect to the perforations 14. The func tion of the slits 15 will become apparent from the dis with means for effectively retaining the closure in a closed _ cussion to follow hereinafter. In addition, the number, position with respect to the container perforations. shape, and relative position of the slits may be varied with Thus, it is one of the objects of this invention to pro out departing from the scope of the invention. vide an improved closure which is not beset with the afore The improved closure 13 comprises a relatively flat mentioned di?iculties. 35 cover piece 16 which, in‘ this instance, de?nes a triangu It is a further object of this invention to provide an im proved closure which is simple, yet sturdy, in construction, attractive in appearance, and automatically prevents clog ging of the container perforations by the material being lar shape of greater proportions than the triangular pat tern formed by perforations 14. The cover piece 16 is provided, along one side thereof, with a pair of tabs 17 which are adapted to embrace a staple or pin 18, carried dispensed therefrom. , , 40 by the container surface 11 in a position adjacent and Further and additional objects will appear from the de substantially parallel to one side of the triangular pattern scription, accompanying drawings and appended claims. formed by perforations 14. The tabs 17 permit the cover In accordance with one embodiment of this invention, piece 16 to be pivoted or hinged about pin 18 as an axis ' an improved closure is provided which is adapted to be used in combination with a surface having a plurality of -~ ' whereby the cover piece either overlies'and closes off the perforations arranged in relatively close proximity to one 45' perforations 14 formed in container surface 11 or un covers the same, depending upon the purpose for which the container is to be used. Cover piece 16 is also pro vided,.along the other two sides thereof, with tabs 20 which tions. The improved closure comprises ‘a cover piece are bent in substantially the same direction relative to the which is pivotally mounted on the surface adjacent the perforations thereof and is adapted, when in one posi 60 cover piece to assume angular positions with respect to the plane of cover member 16, whereby such tabs will be tion of pivotal adjustment, to overlie and close off the inserted in the corresponding slits 15 formed in the con perforations. The cover piece is provided with a tab tainer surface 11 and, thereby, frictionally retain the cover which extends angularly from the periphery thereof and is adapted to be inserted in the surface slit arrangement ‘ 'piece in its closed position as shown in Fig. 1. The tabs and frictionally retain the cover piece in its overlying 55 20 are formed on the periphery of the cover piece 16 and are preferably spaced a substantial distance from the piv position. . otal axis of the cover piece. For a more complete. understanding of this invention, Formed in the central portion of the cover piece 16 are 7 reference should be made to the drawing, wherein: a plurality of protuberances 21, which extend from the Figure 1 is a fragmentary perspective view of a con tainer, showing the improved closure mounted thereon 60 cover piece in substantially the same direction as tabs 20 and, when the cover piece is in the position shown in Fig. "and the cover piece thereof in overlying relation with 1, are adapted to register with and project into or through respect to a plurality of perforations formed in said con another and a slit arrangement formed in said surface in spaced relation with respect to said plurality of perfora the perforations 14 formed in container surface 11. By . _ reason of this fact, protuberances 21 prevent perforations Fig. 2 is similar to Fig. l, but showing the cover piece 65 14 from becoming clogged with the contents of the con of the ‘improved closure in its open position. tainer and, in addition, prevent moisture or foreign mat Fig. 3 is an enlarged sectional view taken along line ter from ?nding its. way through perforations 14, when 3-—3 of Fig. 1. the cover piece 16 is in its closed position.
