BoTTLE'scRUBBEi Filed Nov. 28, 1941 i F; ESTHER /V. Yak/v lNVENTOR 24 E N BY F/G' ATTORNEY mmn emersyj c S1 ra er N.fden,Colbei-t,,Washf t v -;h;pucah.. Nevembrzs',1941;se ialNaazmsr f My invention relates to a bottle scrubber that is formed of resilient materialand is particularly adapted for the manual cleansing j of bottles toremove internal foreign deposits.

An important object of my invention is the provision of a bottle scrubber that may be simply formed according to modern manufac j turing practices from resilient, materials that are long-lived, easily maintained sterile, and may be produced in 'great quantities at low costs.

Anotherobject of the invention is to provide a bottle scrubber. having radiating blades from top to bottom formed of resilient material so that the device may be distorted for insertion into the restricted neck of a bottle tobe cleaned. One other object here is the provision of a bottle'scrubber having novel' and simply joined handle means fora body portion whereby a strong and rigid joinder may be effected A further object of the inventionis the pro vision in a bottle scrubber of spirally helical 4 blades of flexible or resilient material that is effective either when a the device is rotated or reciprocated within a container to be cleaned to cover a maximum of the interior surface. 4

Still another object of my invention is to provide a novel blade structure for use in bottle 'scrubbers whereby through the use of edge flanges on the blades an improved scraping action may be obtained.

Other objects and advantages of theinven- 1 also.

In the drawing: Fig. 1 is a side elevational view of a preferred form ofmy bottle scrubber with a portion of the handle shank omitted for convenience of V illustration,

The shank, herein shown, is produced of twisted wires arranged together in the form of aspiral helix to provide thread-like protrusions on its,

in the stem'the material ofthe stem is stretched and gripshe shank rigidly to effect J'oinder of these elements.

InFigs. 1 and 2 the stem' can beseen to have a plurality of radial blades formed integral therewith and consequently of a resilient nature These blades arearranged spirally about may be slitted at IG'inorder that they may more readily conform to the contours of any surface over which they may be passed. Theulower corners of the bladesjat jl'l are shown extended.

lower than the end of the stem, so that, in the caseof bottles having convex inner surfaces on their bottoms, the shape will insure that comers and the like are also cleaned. r

In the showing of Figs. '7 and 8,, the radial blades 24 protrude from the. stem longitudinally in a manner'parallel'tothe axis of the I stem 20'. .These bladesare also slitt'edfat 2611s, in the, case of the other spiralform of device shown'and'described. V

One additional feature that may be incorporated in the scrubber is' the use, of edge I flanges 3lr and32 that are formed on or attached to the outer edges of the blades accord ing to Figures 51 and 5. 'Theseflanges lie m'opposition to each other'so thatyno matter how the "device is rotated, a scoop-like scraping Fig.. 6 is fragmentary perspective view ."of

the upper portion of the scrubber adjacent'its point of joinder with the handle shank,

action is obtained on the surface beingcleaned to improve theaction of the scrubber. "The slits in the edges of the bladeswill also pass through the flanges. On theouter face of the blade edge V and the flanges, away'from the axis of the stem,

a depression 33 is provided ,so that the actual scraping blade will befslightly under-cut, as may best be seen in Fig.5. The flanges may also a simple.

be used in the blades shown in theiorm of invention appearing in Fig. 7.

In operation, my scrubber is inserted into the container to be cleaned, such as a milk bottle, by forcing it through the usual restricted neck.

This insertion is simple when the resiliency 'of V the device is borne in mind because distortion rotary action ,is probably the best as recipr0-- cation will produce only limited cleaning by scraping due to the limited amount of cleaning face that ispresented to the bottle surface.

In using the slits in the elgesof the blades,

flexing of portions of the blades independent of the remainder may be efiected so that uneven surfaces will be readily accommodated.

It is to be understood that the showing and the description of my invention is purely illustrative and that changes and alterations may be madein materials, size, shape and general arrangement of the parts without departing from the scope and spirit of the subjoined claim.

Having, thus described .my invention, I claim: I A-bottle scrubber comprising a central stem of resilient material and having radial resilient blades, means for manually manipulating said I scrubber from a remote point, and scraper means on each blade edge having the shape of an arcuate portion'of a cylinder wall and attached to said "blade edge'so that its radius of curvature is radially outward'of the blade to which it is attached.
