CHILD-RESISTANT BOX

Abstract

A child-resistant box that includes a container and a pivotally coupled closure. The closure includes one or more projections that can engage with the rolled rim of the container for securing the closure to the container. Under an external downwards force on the closure, the one or more projections can snap over the rolled rim. The closure can be opened by depressing a front wall of the container resulting in the rim moving inwards past one or more projections. Once the rim disengages from the one or more projections, the closure can be lifted and the box opened.

[0027] The following detailed description includes the best currently contemplated mode or modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention since the scope of the invention will be best defined by the allowed claims of any resulting patent.

[0028] Referring to FIGS. 1-5 which shows an exemplary embodiment of child-resistant box 10 that can have a container 100 and a closure 200. The container 100 can include a base 105 and a wall 110, wherein the base 105 and the wall 110 define an inner volume of the container 100. The container 100 can include an open-top for gaining access to the inner volume of the container 100. The container 100 shown in the drawings is rectangular, however, the containers of any other shape and size are within the scope of the present invention. For example, the container and the closure can be square-shaped. The container can be a palm-size container used for storing medicines or psychotropic substances. The container can be made from a medical-grade material, such as a sheet of metal. Coatings of suitable material can also be provided for safety and aesthetic purposes, such as a colored coating can be provided. In one case, the container can be made from a lightweight metal such as tin or aluminum. The rim 115 of the container 100 can be outwardly rolled. The outwardly rolled rim 115 can be more clearly seen in FIG. 6 which shows a sectional side view of the child-resistant box 10.

[0029] FIG. 4 shows the rear view of the child-resistant box 10. Two hinge joints 120 can be seen on the rear side of the child-resistant box 10 that can pivotally couple the closure 200 to the container 100. The rear side of the closure 200 can be coupled to the rear side of the container 100 through the one or more hinge joints 120. The closure 200 can be pivoted between an open state and a close state. FIGS. 3 and 4 show the closure 200 in the closed state, wherein the inner volume of the container is closed by the closure 200 encasing and protecting items contained in the container. FIG. 5 shows the closure 200 in the open state, wherein the inner volume of the container is accessible to put or withdraw an item from the container 100.

[0030] FIG. 3 shows a front of the child-resistant box 10 in the closed state. Two depressions can be seen on the front side of the closure. The closure, as seen in FIG. 5, can include a central section 205 and a skirt 215 extending downwards from a periphery of the central section. The rear side of the skirt can be coupled through hinge joints 120. The front side of the skirt as can be seen in FIG. 3 including two depressions that projects inwards as two half-moon shape projections 210. FIG. 5 shows the two half-moon shape projections 210 which are round or curved at the bottom and flat at the top. The projection 210 can be more clearly seen in FIG. 6 with a round or curved bottom and a flat top. FIG. 5 shows two such projections 210, however one or more of such projections are within the scope of the present invention.

[0031] Referring to FIG. 6, which shows the projections 210 engaged to the rim 115 of the container 100. The space between the projection 210 and the central section 205 of the closure can be proportionated to a thickness of the rim 115 of the container. To close the container, the closure can fall upon the container, however, the projection 210 is retained against the rim 115 preventing the closing of the closure. The closure can then be depressed downwards using suitable force, which may result in the rolled rim snapping over the projections 210. Because of the curved bottom of the projections, the projection 210 can smoothly slide over the rolled rim 115, and the rim snaps into the space between the projection and the central section of the closure. The projection 210 engaged to the rim 115 prevents opening of the box 10.

[0032] To open the closure, the front wall of the container 100 can be depressed inwards. At least the front wall of the container can be configured to be resiliently deformable. In one case, the box can be grasped in two hands with the thumbs placed on the front wall of the container. Thereafter, a force can be applied by the thumbs over the front wall of the container causing the front wall to bend slightly inwards resulting in the rim of the container moving inwards passing a width of the projection 210. When the rim 115 is just past the projection 210, the closure can be lifted resulting in the opening of the box. Alternatively, the front side of the skirt can be pulled outwards and upwards resulting in disengagement of the projection 210, and the closure can be lifted.

[0033] In one alternate embodiment, instead of the rolled rim, a similar but inverted half-moon shape projection can be provided on the outer surface of the front wall of the container and adjacent to the rim. The projection 210 on the skirt of the closure can engage with the inverted half-moon shape projection on the container.

[0034] In an alternate embodiment, instead of the rolled rim, grooves can be provided on the front wall of the container and adjacent to the rim, wherein the half-moon shape projections on the skirt of the closure can be received into the grooves.

[0035] While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
