Sliding cover safety package

A sliding cover safety package comprising:

• a container having a cover mounted thereon for longitudinal slidable movement in one direction from a closed position with respect to said container to an open position, and in the opposite direction to return from said open position to said closed position;
• said cover having a base portion and a pair of spaced, parallel side skirt members depending therefrom;
• a cover locking element projecting inwardly from each side skirt member near one end thereof;
• a slide member projecting inwardly from each side skirt member near the other end thereof;
• said container having a pair of spaced, parallel side wall members received between said side skirt members, and a pair of spaced end wall members extending between said side wall members;
• a flange projecting outwardly from the end of each of said side wall members and overlying the cover locking member and slide member of the adjacent side skirt member;
• a container locking member depending from each of said flanges intermediate the ends thereof;
• said cover having a closed and locked position with respect to said container in which said base portion completely overlies the space enclosed by said side wall members and end wall members of said container and is spaced from said flanges in a fixed axial position with respect thereto, and in which said cover locking elements and slide members engage the underneath side of the respective flanges of said container with each of said container locking members being located in the path of the respective one of the cover locking elements to prevent sliding movement of the respective cover locking element along said flange in said one direction;
• an end skirt extending between said side skirts at said other ends thereof;
• cooperating stop ribs formed on said end skirt and the adjacent end wall engageable in the closed position of said container to prevent movement of said cover in said opposite direction with respect to said container when said cover is in the closed position;
• said cover having an unlocked position in which the space between said base portion and said flanges is reduced to displace said slide members and container locking elements from the underneath sides of the respective flanges with the container locking elements out of the path of movement of the respective cover locker elements to permit movement of said cover in said one direction with respect to said container;
• a pair of spaced, elongated spring members extending between a respective one of the side walls of said container and the base of said cover in parallel relationship with said side walls;
• each of said spring members being integrally formed on one of said respective side walls and base of said cover with a free edge slidably engaging the other of said respective container side walls and base of said cover to resiliently bias said base to said fixed axial position and hence said cover to said locked position to permit movement of said cover from said closed position only subsequent to deflection of said spring members by movement of said base toward said flanges from said fixed axial position;
• and interengageable latching means formed on said cover and container for resiliently latching said cover in a latched position against movement in said one direction with respect to said cover from said closed and locked position, said latching means being disengageable by slight movement of said cover in said one direction against the resilient force of said latching means, said container locking elements being spaced longitudinally from the respective cover locking elements when the cover is closed and latched with the base portion thereof in said fixed axial position to permit the cover to move in said one direction a distance sufficient to permit slight opening movement of said cover before said cover locking elements come into engagement with said container locking elements.
