The present invention relates to containers such as hinge cover tablet boxes and the like and has particular reference to releasing the cover from a closed and locked position so that the box may be readily opened.
An object of the invention is the provision of a hinge cover tablet box or the like wherein the front edges of the box cover and body are formed with locking nodes and a pressure opening projection so that a pressure applied on the projection at the front edge of the body will spring it inwardly sufficiently to release the locking nodes and thereby permit easy opening of the cover by a hinging action thereof.
Another object is the provision of such a tablet box wherein the cover is secured in place by a pintle hinge, the pintle of which is retained under tension so that when the cover is released from a closed position, the tension in the pintle will quickly snap the cover open into a partially opened position where it will remain until further opened by hand.
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.
Referring to the drawing:
Figure 1 is a perspective view of a tablet box embodying the instant invention, the view showing the cover of the box in closed position;
Fig. 2 is an enlarged rear elevation of the box shown in Fig. 1;
Figs. 3 and 4 are enlarged sectional views taken substantially along planes indicated by the lines 3-3, 44 in Fig. 1, the two views showing the cover in different positions, Fig. 4 illustrating portions of a hand in the act of initially opening the box; and
Fig. 5 is an enlarged fragmentary front elevation of a modified form of the box shown in Fig. 1.
As a preferred embodiment of the instant invention, the drawing illustrates a rectangular shaped sheet metal tablet box which includes a body member II and a cover member 12 permanently connected by a pintle hinge 13. These box members are preferably of a shallow, onepiece die drawn construction.
The body member I l comprises a flat bottom wall section I5 (Fig. 3) which at its outer edges merges into a continuous, surrounding upright wall IS. The upright wall includes a front wall section IT, a rear wall section l8 and a pair of connecting side wall sections l9.
against inadvertent opening.
The cover member l2 comprises a semi-fiattended, dome shaped top wall section 2| which at its outer edges merges into a continuous, surrounding and depending flange wall 22. The flange wall includes a front wall section 23, a rear wall section 24, and a pair of connecting side wall sections 25. When the cover is in closed position on the body these depending cover wall sections extend'down adjacent to and outside of the corresponding wall sections of the body.
The hinge I3 preferably includes a straight wire pintle 2'! (Figs. 2 and 3) which is tightly secured in a hinge lug 28 formed in the rear wall section 2 5 of the cover. The ends of the pintle extend beyond the cover hinge lug 28 and are disposed in a pair of spaced hinge lugs 29 formed in the rear wall section N3 of the body II.
The rear wall section H; of the body, if de-- sired, may be offset or flexed inwardly a slight distance at its intermediate portion to accommodate and insure clearance for the inner terminal portion of the cover hinge lug 28, in which the pint1e2'l is tightly secured, as best seen in Figs. 3 and 4.
When the cover is in closed position the inside surface of the top wall section 2!, adjacent the hinge engages against the top edge of the body rear wall section, 18 or at the opposite end portions of the latter and hence raises the cover hinge lug 28 slightly out of alignment with the. body hinge lugs 29. This springs the wire pintle into a curved position as shown in Fig. 2 and thus puts the pintle under a tension so that opening of the cover as hereinafter explained will be facilitated.
The cover is locked against accidental opening when in closed position on the body. For this purpose the body front wall section I? is provided with a pair of spaced outwardly projecting nodes or projections 33 (Fig. 4). Similar nodes or projections 34 (see also Fig. 1) are formed in the cover front wall section 23. These two pairs of nodes engage or lock together when the cover. is in closed position and thus retain the cover Provision is made for easy opening cover when desired. This is effected by means of an outwardly extending button 36 (Figs. 1, 3 and 4) which is formed in the front wall section ll of the body ll. middle of the wall section, between the two spaced locking nodes 33. erably of oval or wheat shape as shown in Fig. 1 so that it is more easily actuated by thumb pressure. The frontwall 23 of thecover is relieved of the The button is located in the 1 This button is prefalong its front edges.
or cut away in an arcuate or curved clearance section 37 in order to clear the button and facilitate easy engagement and manipulation thereof.
A slight thumb pressure on the button 36 while holding the back edge of the box with forefinger and middle finger, moves the front wall section I"! of the body inwardly sufiiciently to disengage the body nodes 33 from the cover nodes 34, thereby releasing the cover for its initial opening. This releasing of the cover permits the hinge pintle to spring back into its original straight position and in so doing it snaps the cover upwardly into its initial or partially opened position as hereinbefore mentioned and as shown in Fig. 4. The initially "opened cover may thereupon be grasped with the other hand and raised into a fully open position to gain access to the box interior.
Upon closing the cover it may be again locked into position by a mere pinching of the box This action will snap the locking nodes into re-engagement and thus lock the cover in place.
Fig. illustrates a slightly different embodiment of the inventioninvolving a slightly difa.
ferent shape as to some parts without in any way altering the operation. In this modifiedform'a round opening button 41 -is substituted for the wheat shaped button in .thefront wall I? of the body ll and a rounded clearance section 42 is in the same manneras the wheat-shaped button.
It is thought that the invention and many of its attendant advantages willbe understood from the foregoing'description, and itwill be appar ent that various changes may-bemade in the form, construction and arrangementof the'parts without departing from the spirit and scope of the invention orsacrificing all ofits material advantages, the form hereinbefore described-being merely a preferred embodiment thereof.
