POWDER BOX I Filed Sept. 27. 1945 F lbra M; 7(ack/ey Jane 7 W/u'fman 9. JW M Patented Jan. 7, 1947 POWDER BOX Flora M. Kackley, Faversham, England, and Jane Whitman, Great Neck, N. Y.; said Whitman assignor to said Kackley Application September 27,1945, Serial No. 618,946

6 Claims. (01. 229-45) This invention relates to boxes for the reception and holding of loose or pulverant material types for holding face .powder permit the discharge and escape of the powder when the box is opened, closed or otherwise handled. An example of this is found in the opening of a box of the usual type in which the cover and bottom parts telescope in closing and the cover extends downwardly over and about the sides of the bottom. When such a box'is opened by raising the lid a vacuum is created within the box into which air rushes when the lid is fullyremoved, thus causing the powder to be disturbed and discharged from the bottom part. It has been suggested to prevent this by utilizing a closure of the slide type but this has not proved to be satisfactory for the reason that when the slide lid is closed it often moves under heaped-up powder which is thus left outside the box causing both wastage and undesired spilling.

It is the principal object of the invention to prevent these undesired effects by providing new and improved closure means for powder'boxes which are operative to prevent the spilling or other release or discharge of the powder upon opening or closing of the closure or upon any movement of the box, as by upsetting. It is particularly useful as a package, suitable for shipping and for mass production by maufacturers.

It is a further object of the invention to provide a box having a primary closure and a secondary closure which is moved to open and closed position by the movement of the primary closure.

A further object of the invention is to provide a closure for a powder box which will comprise a primary closure of the slide typeand a secondary closure which is connected to be operated by the movement of the primary closure and which is flexible whereby it will be bent to open or closed position.

Other objects and features of novelty of the invention will be made apparent by the follow ing description and the annexed drawing which disclose a structure which is illustrative of the 2 invention but imposes no limitations thereon not imposed by the appended claims.

Referring to the drawing, in which similar reference numerals refer to like parts,

Fig. 1 is a perspective view of a box incorporating closure means according to my invention;

Fig. 2 is a view which is similar to Fig. 1 but shows the closure means in open position, and

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

In the drawing there is disclosed a powder box which is illustrative of the invention and which comprises a lower container part 2, within which the powder is received, and a cover part 4 which is of the usual type which telescopes downwardly over the lower container part and comprises the side walls 6 and top 8. The top 8 is provided with an opening i0 therethrough which, in the disclosed embodiment is rectangular, of less-area than the top 8 and is disposed centrally thereof.

, This opening provides access to the powder within the box as inthe normal use of the box the cover part 4 is never removed.

Means are provided by the invention for closing the opening Ill in order to retain the powder therein and which may be moved to uncover the opening in such a manner that easy access to the powder may be had. Such means comprise a slide type cover comprising a fiat, preferably stifi member 20 which is positioned closely beneath the top part Band which is of larger area than the opening ID in the top part in order that when in closed position it will completely cover the opening in and hold the powder within the box. sliding movement of the cover member 20 to open and closed positions is permitted by an elongated opening or slot 22 in one of the side walls 6 of the cover part 4 and in the plane of the member 20. The sliding cover 2|] may be provided with oppositely and laterally extending ears 24 at the inner end thereof, 1. e. the end remote from the slot 22, in order to prevent complete. withdrawal thereof through the opening 22 when the slide is moved to open the box. A tab .26 extends outwardly from the outer edge of the slide 20, i. e. the edge adjacent the slot 22, and provides a means for manually operating the sliding cover.

A secondary cover for the boxis provided by the invention and comprises a flexible member 30 which underlies the slide 20 and is independent thereof except for the operating connection to be described hereinafter. This flexible cover is connected to the container part 2 of the box adjacent the slot 22 and is of approximately the same area as the opening III in the top in order that it may be moved therethrough from closed to open position as it bends due to its own flexibility. Movement of this inner cover is effected by means of a connection between the outer end of the sliding cover 20 and the remote or inner end of the flexible member 30, which connection may be made by any suitable means such as the ribbon 3; or, if desired, by an integral extension of either the member .30 or the sliding cover.

The closure means which have been described and illustrated are normally in the closed posiof the box interior of the box and means for closing said tion shown in Fig. 1 in which the flexible closure member 30 closely overlies the powder within the container part of the box and is itself held in place by the sliding cover which is, of course, held in place byethe parts of the top 8 which surround the opening Hi. When it is desired to open the box the sliding cover is moved to open position and through the connecting means 32 pulls on the flexible closure causing the same to be lifted from a closed to an open position, as shown in Fig. 2, giving access to the powder within the box. The initial movement of the sliding cover necessarily flexes the inner part of the flexible cover, thereby gradually opening the box, overcoming any tendency for the contents opening, said means comprising a sliding cover and a second flexible coverunderlying said sliding cover when in closed position and bendable means connecting the free end of said flexible cover to the opposite end of said sliding cover for causing said flexible cover to be initially flexed and thereafter moved to open position by movement; of the sliding cover to open position.

3. A box comprising a bottom, sides, a top having an opening therein giving access to the interior of the box and means for closing said opening, said means comprising a sliding cover and a second flexible cover secured at one end of said box underlying said sliding cover when in closed position and flexible means connecting the free end of said flexible cover to an opposite end of said sliding cover for causing said flexible cover to be initially flexed andthereafter moved to open position through said opening by movement of the sliding cover to open position.

to be spilled by a rush of air into the box and this flexible cover remains flexed as indicated in Figure-2 until approaching closing position when it unbends into the position of Figure 1 and, as indicated in Figure 3, the sliding cover can con: tinue its closing movement after the cover has closed the opening. When the slide is moved inwardly to closed position the flexible inner closure 32 is consequently mov'ed downwardly into engagement with the powder, compressing it into the box and holding it therein.

It will be apparent that many departures may be made from the embodiment of the invention described and illustrated in this application without departing in any way from the invention. For example, it is not at all necessary in practicing the invention to use a boxof the telescoping type disclosed herein. Further, it may be found desirable to employ some type of means for opening the sliding cover 20 other than the tab 26. All such modifications, as well as others which will occur to those skilled in the art, may be made and practiced without departing in any way from the spirit or scope of the invention, for the limits of which reference must behad to the appended claims.

What is claimed is:

1. A box comprising a bottom, sides, a top having an opening therein giving access to the interior of the box and means for closing said opening, said means comprising a sliding cover and a second flexible cover underlying said sliding cover when in closed position and bendable means connecting one end of said flexible cover to the opposite end of said sliding cover for caus- & ing said flexible cover to be initially flexed and thereafter moved to open position through said opening by movement of the sliding cover to open position.

4. A box comprising a bottom, sides, a top having an opening therein giving access to the interior of the box and means for closing said opening, said means comprising a sliding cover and a second cover of flexible material underlying said sliding cover when in closed position and bendable means connecting one end of said flexible cover to an opposite end of said sliding cover for causing said flexible cover to be initially flexed and thereafter moved to open position by movement of the sliding cover to open position thereby gradually opening said box.

5. A box comprising a bottom, sides, a top having an' opening therein giving access to the interior of the box and means for closing said 'opening, said means comprising a sliding cover mitted to unbend in closing whereby its end will drop upon the contents within said box.

6. A box comprising bottom, sides, atop having an opening therein giving access to the interior of the box and means for closing said opening, said means comprising a sliding cover and a second cover of flexible material underlying said sliding cover when in closed position and a ribbon connecting one end of said flexible cover to an opposing end of, said sliding cover for causing said flexible cover to be initially flexed and thereafter moved to open position through said open- FLO-RA M.
