Abstract
Abstract A child-resistant package includes a tray with a compartment therein for receiving articles to be packaged, and a cover member slideably received on the tray and movable relative to the tray between opened and closed positions. The cover member is a flexible member having a top wall and peripheral sidewalls. The peripheral sidewalls of the cover member overlie peripheral sidewalls of the tray and latching members on the sidewalls of the cover member and tray cooperate to retain the cover member in a closed position relative to the tray. The latching members are released by applying an inward pressure to the top wall of the cover member, to thereby bias the sidewalls of the cover member outwardly relative to the sidewalls of the tray. An abutment member on the tray prevents such inward deflection of the top wall of the cover member in the event that a child bites down on the package in the forward region thereof. Preferably a peripheral skirt is provided on the tray for overlying lower marginal surfaces of the peripheral walls of the cover member, to thereby prevent a child from wedging his or her teeth between the peripheral walls of the cover member and tray, and thereafter prying the cover member off of the tray.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
237 words
A child-resistant package including: a tray having a bottom wall and peripheral rear, front and sidewalls defining a compartment for receiving articles to be packaged; a cover member slideably retained on said tray and movable between an opened and closed position relative to said tray, said cover member being a flexible member having a top wall and peripheral sidewalls and said top wall overlying and covering the compartment when the cover member is in a closed position relative to said tray; said sidewalls of said tray and of said cover member including cooperating latching members normally engaging each other when the cover member is in a closed position relative to said tray for preventing relative sliding movement between said tray and cover member to an opened position; said sidewalls of the cover member being biased outwardly from the sidewalls of the tray by inwardly deflecting the top wall of the cover member to thereby permit the cooperating latching members to disengage from each other to permit the cover member to be slid relative to the tray into an opened position; and abutment means adjacent a front end of the tray for impeding inward deflection of the top wall of the cover member adjacent the front wall of the tray to thereby make it difficult for an infant to release the latching members and open the package by biting down on said package at the front end thereof.
Claim 2
Dependent Claim
237 words
A child-resistant package including: a tray having a bottom wall and peripheral rear, front and sidewalls defining a compartment for receiving articles to be packaged; a cover member slideably retained on said tray and movable between an opened and closed position relative to said tray, said cover member being a flexible member having a top wall and peripheral sidewalls and said top wall overlying and covering the compartment when the cover member is in a closed position relative to said tray; said sidewalls of said tray and of said cover member including cooperating latching members normally engaging each other when the cover member is in a closed position relative to said tray for preventing relative sliding movement between said tray and cover member to an opened position; said sidewalls of the cover member being biased outwardly from the sidewalls of the tray by inwardly deflecting the top wall of the cover member to thereby permit the cooperating latching members to disengage from each other to permit the cover member to be slid relative to the tray into an opened position; and abutment means adjacent a front end of the tray for impeding inward deflection of the top wall of the cover member adjacent the front wall of the tray to thereby make it difficult for an infant to release the latching members and open the package by biting down on said package at the front end thereof.
Claim 3
Dependent Claim
25 words
The child-resistant package of claim 1 wherein the abutment means is a rib integrally molded as part of the tray in the inner compartment thereof.
Claim 4
Dependent Claim
24 words
The child-resistant package of claim 2 wherein said abutment means is a rib integrally molded to the front and bottom walls of said tray.
Claim 5
Dependent Claim
21 words
The child-resistant package of claim 2 wherein said abutment means is located substantially midway between the peripheral sidewalls of the tray.
Claim 6
Dependent Claim
80 words
The child-resistant package of claim 1 wherein the tray includes a peripheral skirt extending transversely beyond each of the sidewalls of said tray adjacent the bottom wall of said tray, said sidewalls of the cover member having lower marginal edges overlying and closely adjacent the peripheral skirts for preventing a child from wedging his or her teeth between the sidewalls of the cover member and the sidewalls of the tray and thereafter prying the cover member off of said tray.
Claim 7
Dependent Claim
58 words
The child-resistant package of claim 5 wherein said cover member includes a peripheral rear wall joined to the sidewalls of said cover, said tray including a peripheral skirt extending rearwardly from the rear wall of said tray adjacent the bottom wall of said tray for overlying a lower marginal edge of the rear wall of the cover member.
Claim 8
Dependent Claim
49 words
The child-resistant package of claim 1 including visually discernible areas on the outer surfaces of the top wall of the cover member and the bottom wall of the tray, said areas being engageable for the purpose of sliding the cover member relative to said tray into an opened position.
Claim 9
Dependent Claim
39 words
The child-resistant package of claim 7 wherein said visually discernible areas include serrations or ribs on the outer surface of the top wall of the cover member and on the outer surface on the bottom wall of the tray.
Claim 10
Dependent Claim
43 words
The child-resistant package of claim 8 wherein a pair of serrated or ribbed areas are provided on the outer surface of the top wall of the cover member, said pair of serrated areas being located on opposite transverse sides of the abutment means.
Claim 11
Dependent Claim
37 words
The child-resistant package of claim 9 wherein said abutment means is a rib integrally molded as part of the tray to the inner compartment thereof and being disposed substantially midway between the peripheral sidewalls of the tray.
