Abstract
Abstract An appliance or utensil for removing remaining relatively viscous materials in bottles or containers having a relatively restricted neck. The appliance embodies a handle which is insertable through the neck of the bottle and an operative element in the form of a channel member having flexible side walls so that it can be rotated against the interior surface of the bottle with a side wall of the channel rubbing against the surface so as to pick up or gather in the channel the remaining viscous material in the bottle. The channel member is then removed through the neck of the bottle carrying the gathered material with it. The material is then removed from the channel by means of a pusher moved along the length of the channel member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
185 words
As an article of manufacture: an applicance having a handle member adapted for removing relatively viscous material remaining in a bottle or container having an enlarged body and a relatively restricted neck part, the body having several times the diameter of the neck part, an active element in the form of a channel member affixed to the end of the handle member, the active element being formed of relatively flexible material and configurated to form a channel having spaced side members and at least one side member adapted to be placed against the inside surface of the bottle and rotated so that the material in the bottle is gathered in the channel member, the channel member being of a size which is substantially that of the restricted neck so that it can be inserted into and withdrawn through the restricted neck of the bottle without displacement of the said spaced side members from their normal configuration, the appliance including a handle having sufficient flexibility that one full side surface of one of said side members can be pressed against the inside surface of the bottle.
Claim 2
Dependent Claim
185 words
As an article of manufacture: an applicance having a handle member adapted for removing relatively viscous material remaining in a bottle or container having an enlarged body and a relatively restricted neck part, the body having several times the diameter of the neck part, an active element in the form of a channel member affixed to the end of the handle member, the active element being formed of relatively flexible material and configurated to form a channel having spaced side members and at least one side member adapted to be placed against the inside surface of the bottle and rotated so that the material in the bottle is gathered in the channel member, the channel member being of a size which is substantially that of the restricted neck so that it can be inserted into and withdrawn through the restricted neck of the bottle without displacement of the said spaced side members from their normal configuration, the appliance including a handle having sufficient flexibility that one full side surface of one of said side members can be pressed against the inside surface of the bottle.
Claim 3
Dependent Claim
31 words

Claim 6
Dependent Claim
37 words
An article as in claim 1 including a member having a part configurated to fit into the active element and to be moved along the element to push the contents held therein out of one end thereof.
