DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
(17) FIG. 1 is an illustration of the paperboard box 100 that is configured in a child-resistant manner. With reference to FIG. 1, the paperboard box 100 is formed from a paperboard over-sleeve 110 and a paperboard tray 115 that is lockingly inserted within the paperboard over-sleeve 110 to create a locked storage compartment.
(18) The paperboard box 100 is constructed from a material, such as cardboard, which provides resistive properties, while at the same time is thin enough to be folded into the final form of the paperboard box 100. The paperboard box 100 is manufactured from 18 point to 22 point, preferably 20 point, board grade paper, which is a grade of paper made for packaging, as opposed to finished grade paper. The paper grade has been found to be a critical aspect of the invention and thus it has been found that the grade of 20 points provides the optimal level of resilience to provide required resistive or properties associated with resilience. The paperboard over-sleeve 110 and paperboard tray 115 are folded into mutually engaging rectangular forms, where the final assembly is held in shape via a suitable glue, in a manner known to the skilled person. In order to provide resistance to merely tearing the paperboard box 100 apart to gain entry, the box is provided with a plastic laminate layer. In this way, a child cannot simply tear the box apart without resorting to more destructive methodologies, such as cutting the box with scissors.
(19) As shown in FIG. 1, the paperboard over-sleeve 110 includes a flap that includes first and second sleeve tabs 120a, 120b, where the first sleeve tab 120a is resiliently biased in a manner that resists transverse or lateral movement of the paperboard tray 115 when the paperboard tray 115 is in the closed position, as depicted in FIG. 1. The second sleeve tab 120b engages with a first tray tab 135 of the paperboard tray 115 (see FIG. 3) in a locking manner when the paperboard tray 115 is pulled along the longitudinal axis of the paperboard box 100 to an open position.
(20) FIG. 2 shows an end view of the paperboard box 100 in accordance with the invention. Here, a sleeve divider tab 125 is shown arranged adjacent to the paperboard tray 115. The sleeve divider tab 125 extends along the interior of the paperboard tray 115 and creates a channel within which the paperboard tray 115 is locked in place by the sleeve divider tab 125. The sleeve divider tab 125 is circumferentially rotatable about an axis that extends lengthwise or longitudinally of the paperboard box 100 to permit transverse or lateral movement of the paperboard tray 115 when seeking to open the paperboard tray 115 to gain access to product stored within the paperboard tray 115.
(21) FIG. 3 is an illustration of the paperboard tray 115 in accordance with an embodiment of the invention. With reference to FIG. 3, the paperboard tray 115 is formed in the shape of a rectangle and includes an upper opening 130, a first tray tab 135 and a second tray tab 140, where the first tray tab 135 engages in a locking manner with the second sleeve tab 120b of the paperboard tray 115 (see FIG. 1) when the paperboard tray 115 is pulled along the longitudinal axis of the paperboard box 100 to the open position.
(22) FIG. 4 is an illustration of the paperboard tray 115 in accordance with a preferred embodiment of the invention. In the preferred embodiment, the paperboard tray 115 has closed upper and lower surfaces, where an opening is provided at one end that includes a first tray tab 135 and a second tray tab 140, where the first tray tab 135 engages in a locking manner with the second sleeve tab 120b of the paperboard tray 115 (see FIG. 1) when the paperboard tray 115 is pulled along the longitudinal axis of the paperboard box 100 to the open position. As opposed to providing the upper opening 130 of the prior described embodiment, the presently contemplated preferred embodiment includes cutouts 145a, 145b, in this way, the paperboard tray 115 of the preferred embodiment is easier to manufacture and more flexible in the types of product that can be housed in the paperboard box 100 without adding an additional piece or insert.
(23) FIG. 5 is a plan view illustration of the paperboard over-sleeve 110 in an unfolded state in accordance with the invention. As depicted in FIG. 5, the paperboard over-sleeve 110 has a flap that includes the first and second sleeve tabs 120a, 120b, the divider tab 125, first and second u-shaped cutouts 150, 155, a triangular shaped cutout 160, an internal sleeve locking tab 165 and an upper sleeve tab 170. In assembled form, the first sleeve tab 120a is resiliently biased in a manner that resists transverse or lateral movement of the paperboard tray 115 when the paperboard tray 115 is in the closed position depicted in FIG. 1. The second sleeve tab 120b engages, in a locking manner, with a first tray tab 135 of the paperboard tray 115 (see Fla 3) when the paperboard tray 115 is pulled along the longitudinal axis of the paperboard box 100 to an open position to prevent complete removal of the paperboard tray 115 from within the paperboard over-sleeve 110. The internal tray locking tab 165, on the other hand, engages with the first tray tab 135 of the paperboard tray 115 and prevents the paperboard box 100 from being opened through normal force when attempting to slide the paperboard tray 115 from within the paperboard over-sleeve 110 to reveal its contents. The first and second u-shaped cutouts 150, 155 are provided to permit access during removal of the paperboard tray 115.
(24) FIG. 6 is a plan view illustration of the paperboard over-sleeve 110 in an unfolded state in accordance with an alternative preferred embodiment of the invention. Here, the paperboard over-sleeve 110 is provided with a folding indentation section 180 that rests against the sleeve divider tab 125 when the paperboard tray 115 is locked in place by the sleeve divider tab 125 (see FIGS. 7 and 8). By providing the folding indentation section 180, the sleeve divider tab 125 requires a greater level of force to circumferentially rotate the sleeve divider tab 125 in the direction indicated by arrow A (see FIG. 9). When the required force is provided, e.g., when opening the paperboard box 100, the folding indentation section 180 moves into a final position in the direction indicated by arrow(s) C (see FIGS. 7 and 9), whereby the inner edge of the folding indentation section 180 moves to a position to form a planar edge with the upper edge of the paperboard over-sleeve 110.
(25) FIG. 10 is a plan view of the paperboard tray 115 in an unfolded state. As shown, the paperboard tray 115 includes an opening 130, a first tray tab 135 and a second tray tab 140, where the first tray tab 135 engages in a locking manner with the second sleeve tab 120b of the paperboard tray 115 (see FIG. 1) when the paperboard tray 115 is pulled along the longitudinal axis of the paperboard box 100 to the open position. The first tray tab 135 engages with the second sleeve tab 120b of the paperboard over-sleeve 115 (see FIG. 5) in a locking manner when the paperboard tray 115 is pulled along the longitudinal axis of the paperboard box 100 to an open position. The first tray tab 135 engages with the second sleeve tab 120b of the paperboard over-sleeve 110 and thus prevents the paperboard box 100 from being opened through normal force when attempting to slide the paperboard tray 115 out from the within the paperboard over-sleeve 110.
(26) FIG. 11 is a plan view of the paperboard tray 115 in accordance with the preferred embodiment in an unfolded state. The paperboard tray 115 includes a first tray tab 135 and a second tray tab 140, where the first tray tab 135 engages in a locking manner with the second sleeve tab 120b of the paperboard tray 115 (see FIG. 1) when the paperboard tray 115 is pulled along the longitudinal axis of the paperboard box 100 to the open position. The paperboard tray 115 also includes cutouts 145a, 145b such that the paperboard tray 115 is easier to manufacture and more flexible in the types of product that can be housed in the paperboard box 100 without adding an additional piece or insert.
(27) FIG. 12 shows the paperboard box 100 in a partially opened state. Here, the internal tray locking tab 165 has engaged with the first tray tab 135 of the paperboard tray 115 such that the paperboard tray 115 cannot extend tram the paperboard box 100 through normal force to reveal its content. The locking engagement of the internal tray locking tab 165 with the first tray tab 135 is shown in FIG. 13, which is a cross-sectional illustration along 9-9 of the paperboard box 100 in the partially opened state.
(28) FIG. 14 shows an end view of the paperboard box 100 with the paperboard tray 115 in a locked and inserted state in accordance with the invention. The sleeve divider tab 125 is shown arranged adjacent to the paperboard tray 115. The sleeve divider tab 125 extends along the interior of the paperboard tray 115 and creates a channel within which the paperboard tray 115 is locked in place by the sleeve divider tab 125. The sleeve divider tab 125 is circumferentially rotatable about an axis, in a direction indicated by arrow A, which extends lengthwise or longitudinally of the paperboard box 100 to permit transverse or lateral movement, indicated by arrow B, of the paperboard tray 115 when seeking to open the paperboard tray 115 to gain access to product stored within the paperboard tray 115.
(29) FIG. 15 shows the end of the paperboard box 100 with the paperboard tray 115 at an unlocked and inserted state in accordance with the invention. Here, the sleeve divider tab 125 has been rotated and the paperboard tray 115 has been moved transversely or laterally, in the directions indicated by arrows A and B shown in FIG. 14, such that it is now possible to slide the paperboard tray 115 lengthwise or along the longitudinal axis of the paperboard box 100 to gain access to product stored within the paperboard tray 115. In this state, the second sleeve tab 120b engages with the first tray tab 135 of the paperboard tray 115 (see FIG. 3) in a locking manner to prevent complete removal of the paperboard tray 115 from within the paperboard over-sleeve 110.
(30) FIG. 16 shows the paperboard box 100 in an opened state. Here, the second sleeve tab 120b has engaged with the first tray tab 135 of the paperboard tray 115 (see FIG. 3) in a locking manner to prevent complete removal of the paperboard tray 115 tram within the paperboard over-sleeve 110. The locking engagement of the second sleeve tab 120b with the first tray tab 135 is shown in FIG. 17, which is a cross-sectional illustration along 13-13 of the paperboard box 100 in the opened state.
(31) The inventive child-resistant paperboard box 100 advantageously includes a sleeve divider tab 125 and requires the paperboard tray 115 to be slid from one side to the other so as to “unlock” the paperboard box 100 before the paperboard tray 115 can be pulled from the paperboard over-sleeve 110.
(32) Thus, in accordance with the disclosed embodiments of the invention, in order to open the paperboard box 100, the paperboard box 100 is held in both hands with the top of the box facing up and a first side facing proximately, i.e., toward the body of the person seeking to open the paperboard box. While applying equal pressure to all tabs, they are push down and the paperboard tray 115 is pulled/slid toward the body of the person seeking to open the paperboard box 100.
(33) Once the paperboard tray 115 is completely pulled and touches the wall of the paperboard over-sleeve, fingers are placed on opposite sides of the end of the tray-(one on each side) to pull/slide the paperboard tray 115 from out the paperboard over-sleeve until it catches, i.e., the tabs engage. The box is now open.
(34) In order to close the inventive paperboard box 100, with the paperboard tray 115 fully extended from the paperboard over-sleeve 110, fingers are placed at opposite sides of the ends the paperboard tray 115. The paperboard tray 115 is now slid/pushed distally, i.e., away from the body of the person seeking to close the paperboard box 100 toward the opposite side of the paperboard over-sleeve 110.
(35) Once the paperboard tray 115 is completely pushed to the opposite wall of the paperboard over-sleeve 110, the paperboard tray 115 can now be slid/pushed back into the sleeve until it “clicks” in place to thereby lock the paperboard box 110.
(36) Thus, while there have been shown, described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the methods described and the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements or structure shown which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that elements or structure shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
