Claims
- 1. A blank for forming a U-shaped divider to be placed into subdividable carton:
- a generally rectangular shaped piece of corrugated sheet stock;
- a first pair of spaced apart, parallel score lines extending between a pair of oppositely disposed edges, each score line of the first pair being for use in determining a fold lien;
- a second pair of spaced apart, parallel score lines spaced from said first pair and extending between said pair of oppositely disposed edges, each score line of the second pair being parallel said score lines of said first pair and said score lines of the second pair being for use in determining a fold lien; and

Parent Case Info
This application is a continuation of our copending application Ser. No. 504,849 filed Apr. 5, 1990 and now abandoned.
The invention in general relates to corrugated shipping cartons or containers employed to ship a plurality of items which may be of the container type or of the non-container type.
More particulary the invention relates to shipping cartons or containers having internal partition means separating the items into groups, the arrangement providing that by cutting along exterior guide line means the carton can be divided into smaller independent shipping cartons.
A major defect in the design of such divisible cartons or containers is that where the path of the knife blade moving along guide line means on a side wall deviates from the line by a small amount, the blade cuts into one of the items in the carton.
The invention provides improvements in the partition means which functions to essentially eliminate the likelihood that an item in a carton will be cut even with abnormal deviation of a knife blade from the guide line on a side wall.
The invention contemplates that the partition means be structured to provide spaces inside the carton or shipping container each of which is adjacent to a side wall and co-extensive with the external knife-blade guide line means, each space being dimensioned to receive the end of knife blade being moved along the guide line and cutting the wall and to continue to receive the end of the blade even with substantial deviation from the guide line to thereby maintain the knife blade away from items in the carton and prevent the cutting of same.
The invention in one aspect, contemplates partition means in the form of a pair of C or U shaped dividers inside of a shipping carton, the respective bases of the dividers being closely adjacent to or abutting one another and the legs of the dividers being respectively glued to opposite side walls, the aforementioned knife-receiving spaces being provided by that each leg is joined to its base by space-providing structure preferably a chamfer.
The invention will be shown as employed in shipping medium such as a conventional four-panel corrugated carton or container (regular slotted carton) and as employed in a conventional five panel wrap around carton or container the foregoing being described below in connection with the following drawings wherein. It will be understood of course that the invention can be employed in a 1/2 slotted carton.
