Abstract
Abstract The carton comprises a rectangular inner slide or base member of the utmost simplicity, which is adapted to slide within a sleeve member of somewhat greater length. The sleeve member has a double-bottom comprising an inner panel having an opening therein approximating the size and shape of the horizontal contour of the base member. The added length of the inner panel provides a strap-like abutment at each end of the carton between which the base member may be normally retained. The outer panel of the double bottom of the sleeve member is provided with an opening smaller than the area of the base member but large enough to admit the finger to press the base member upwardly sufficiently to ride over the abutment at either end of the carton.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A carton presenting some difficulty of access by immature or incompetent persons, said carton comprising a base member serving as the container proper and a sleeve member enveloping said base member and in which the latter is adapted to slide, the sleeve member having a bottom wall comprising a lamination of two panels, the inner panel provided with a slight inner upward protuberance at each end between which said base member is retained when the carton is closed, and openings in said panels in partial registry with each other whereby a portion of the bottom of said base member is exposed and may be contacted by the finger through the registering portions of said openings and pressed upwardly to elevate at least one end thereof above the adjacent one of said slight protuberances to free said end for sliding removal of said base member from the sleeve member.
Claim 2
Dependent Claim
148 words
A carton presenting some difficulty of access by immature or incompetent persons, said carton comprising a base member serving as the container proper and a sleeve member enveloping said base member and in which the latter is adapted to slide, the sleeve member having a bottom wall comprising a lamination of two panels, the inner panel provided with a slight inner upward protuberance at each end between which said base member is retained when the carton is closed, and openings in said panels in partial registry with each other whereby a portion of the bottom of said base member is exposed and may be contacted by the finger through the registering portions of said openings and pressed upwardly to elevate at least one end thereof above the adjacent one of said slight protuberances to free said end for sliding removal of said base member from the sleeve member.
Claim 3
Dependent Claim
110 words
The carton as set forth in claim 1 in which, said sleeve member is longer than said base member, the opening in the inner panel of the bottom wall being of the same area as that of the base member, whereby when the carton is closed, the base member seats within said opening and the narrow solid portions of the inner panel at the opposite ends of said inner panel opening constitute said slight protuberances, the opening in the outer one of said bottom panels being smaller than the first opening, whereby only a portion of the base member is exposed thereby for pressure by the finger to release it.
Claim 4
Dependent Claim
50 words
The carton as set forth in claim 2 in which the material of said sleeve is suffiently flexible for enabling the protuberance-carrying End portions of the double bottom wall of the sleeve member to be depressed slightly to assist in freeing the base member when the latter is pressed upwardly.
