Abstract Small glass bottles of unstable configuration are drop packed in several stages to fill a packing case capable of holding a relatively large number of such bottles. Separate slugs of articles are formed to fill predetermined portions of the case in a method which permits use of a conventional drop packer grid.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
213 words
A method for drop packing unstable articles into upwardly open packing cases and comprising the steps of: (a) feeding the articles on a conveyor in end-to-end relationship and in side-by-side columns to fill a drop packer grid of the type having side-by-side lanes for receiving the columns of articles at the downstream end of the conveyor whereby a charge of articles is provided in the grid, adjacent the downstream end of the conveyor, (b) stopping the flow of articles on the conveyor after a predetermined number of articles have entered the grid whereby the charge of articles in the grid are segregated from those being fed toward the grid on the conveyor, (c) mating a portion of the case with a funnel and dropping the charge of articles through the funnel so that only that portion of the case is filled by the charge, and continuing to hold back the flow of articles on the conveyor, (d) moving the case so that another portion is positioned below the grid to receive another charge, and mating that portion with the funnel, (e) allowing the articles to again flow into the grid to form a second charge, (f) dropping the second charge through the funnel and into the case to fill said another portion thereof.

A method for drop packing unstable articles into upwardly open packing cases and comprising the steps of: (a) feeding the articles on a conveyor in end-to-end relationship and in side-by-side columns to fill a drop packer grid of the type having side-by-side lanes for receiving the columns of articles at the downstream end of the conveyor whereby a charge of articles is provided in the grid, adjacent the downstream end of the conveyor, (b) stopping the flow of articles on the conveyor after a predetermined number of articles have entered the grid whereby the charge of articles in the grid are segregated from those being fed toward the grid on the conveyor, (c) mating a portion of the case with a funnel and dropping the charge of articles through the funnel so that only that portion of the case is filled by the charge, and continuing to hold back the flow of articles on the conveyor, (d) moving the case so that another portion is positioned below the grid to receive another charge, and mating that portion with the funnel, (e) allowing the articles to again flow into the grid to form a second charge, (f) dropping the second charge through the funnel and into the case to fill said another portion thereof.
Claim 3
Dependent Claim
33 words
The method of claim 1 further characterized by the steps of lifting the case upwardly to mate with the funnel prior to dropping the charges of articles into the portions of the case.
Claim 4
Dependent Claim
42 words
The method of claim 2 wherein the case is lowered onto a conveyor for movement into position to receive the second charge of articles and prior to said lifting step for mating the case with the funnel for dropping the second charge.
