(01. 229-45‘) ' This invention relates to boxes for the recep tion and holding of loose or pulverant material‘ such as powder and, more particularly, relates to covers or closures for such boxes. 2 invention but imposes no limitations thereon not imposed by the appended claims. _ Referring to the drawing, in which similar ref erence numerals refer to like parts, I Fig. 1 is a perspective view of a box incorporat While the invention has utility with respect to all types of boxes, regardless of the contents or intended use thereof, it is particularly‘useful ing closure means according to my invention; Fig. 2 is a view which is similar to Fig. 1 but when applied to boxes which hold, or are intended shows the closure means in open position, and Fig. 3 is a sectional view taken on line 3-3 of to hold, pulverant of granular material and in this application the invention will be described 10 Fig. 1. holding face powder. - ,In the drawing there is disclosed a powder box in connection with and as applied to a box for which is illustrative of the invention and which \ comprises a lower container part 2, within which It is well known that boxes of usual and known the powder is received, and a cover part 4 which charge and escape of the powder when the box 15 is of‘ the usual type which telescopes downwardly over the lower container part and comprises the - is opened, closed or otherwise handled. An ex side walls 6 and top 8. The top 8 is provided ample of this is found in the opening of a box with an opening i0 therethrough which, in the of the usual type in which the cover and bottom disclosed embodiment is rectangular, of less-area parts telescope in closing and the cover extends downwardly over and about the sides of the 20 than the top 8 and is disposed centrally thereof. , This opening, provides access to the powder with bottom. When such a box'is opened by raising the lid a vacuum is created within the box into in the box as inthe‘normal use of the box the cover part 4 is never removed‘. ‘ which air rushes when the lid is _fully- removed, Means are provided by the invention for clos thus causing the powder to be disturbed and dis charged from the bottom part. It has been sug 25 ing the opening Ill in order to retain the powder ' gested to prevent this by utilizing a closure of the therein and which may be moved to uncover the opening in such a manner that easy access to the slide type but this has not proved to be satis powder may be had. Such means comprise a factory for the reason that when the slide lid is slideltype cover comprising a ?at, preferably closed it often moves under heaped-up powder which is thus left outside the box causing both 30 sti? member 20 which is positioned closely ' types for holding face .powder permit the dis wastage and undesired spilling. beneath the top part Band which is of larger area than the opening ID in the top part in order It is the principal object of the invention to prevent these undesired effects by providing new that‘ when in closed position it will completely and improved closure means for powder'boxes ' cover the opening in and hold the powder within which are operative to prevent the spilling or _ the box. sliding movement of the cover mem other release or discharge of the powder upon ber 20 to open and closed positions is permitted ' opening or closing of the closure or upon any by an elongated opening or slot 22 in one of the side walls 6 of the cover part 4 and in the plane of movement of the box, as by upsetting.

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 second-‘ ary 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 50 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 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 ?exible member 30 which underlies the slide 20 and is independ ent thereof except for the operating connection to be described hereinafter. This ?exible cover is connected to the container part 2 of the box adjacent the slot 22 and is of approximately the r 2,418,923 3 same area as the opening III in the top of the box ' in order that it may be moved therethrough from closed to open position as it bends due to its own ?exibility.
