Abstract
The invention involves a childproof box that suitable for medicinal items such as tablets, medication or other consumables that may be desirably restricted from children. The childproof mechanism that restricts access to the contents of the box may employ a base shell that slides in and out of a cover shell, which respectively conceals and exposes a storage cavity. Both shells have corresponding tracks and corresponding protrusions configured to engage with each other in a manner so that the base shell may only be accessed (or slid open) when a user presses and pushes on a top surface of the cover shell. The structural elements of each of the shells are such that a user may operate the childproof box with a single hand. In exemplary embodiments, the childproof box comprises of flat surfaces that form a generally rectangular box, which is easy to carry, manipulate and store.

(25) Turning now to the figures, FIG. 1 illustrates a perspective view of a childproof box in accordance with an exemplary embodiment of the present invention, shown in a close position. More specifically, FIG. 1 shows childproof box 100, which comprises flexible cover shell 101 and rigid base shell 102. Rigid base shell 102 slidably registers inside a cavity of flexible cover shell 101. Both shells include complementary elements that register together or engage to form locking components 103 and 104 and retention components 105 and 106 (see FIG. 2), which are located internally (when closed as in FIG. 1) protruding from side walls of each shell. Locking components 103 and 104 prevent rigid base shell 102 from being easily slid into an open position (unless operated to disengage the same). Retention components 105 and 106 prevent rigid base shell 102 from being completely removed or decoupled from flexible cover shell 101.
(26) Flexible cover shell 101 is typically made of a plastic or copolymer implementing a density, strength, and hardness such that the cover shell is flexible. Moreover, certain structural elements may be implemented such as aperture 119a (see FIG. 4(f)) in order to improve a flexibility for the cover shell. Conversely, rigid base shell 102 is typically made of a plastic or copolymer implementing a density, strength, and hardness such that the base shell is rigid and does not bow or flex when pressed upon. This configuration of childproof box 100 aids in the safety aspect of the receptacle, because it is more difficult for small children to open by, for example, biting the box or plying it open. Moreover, this configuration makes operation of childproof box 100 easily manageable with a single hand so that elderly adults or adult users with diminished strength can operate childproof box 100 with ease.
(27) In exemplary embodiments, each shell is rectangular as shown in the figures, although in other embodiments a square shape may be implemented without deviating from the scope of the present invention. A childproof box in accordance with the present invention may be constructed using one or several types of plastics or polymers. In exemplary embodiments however, plastic resins certified as USP Class VI may be utilized so that the receptacle is suitable as a medical devicethis may be useful for implementation with prescription or non-prescription medications, other medicinal items and edibles or consumables that be desirably restricted from children.
(28) Turning now to the next figure, FIG. 2 illustrates a perspective view of childproof box 100, shown in an open position. More specifically, FIG. 2 depicts rigid base shell 102, which has been slid out of a cavity extending through opening 110 within flexible cover 101 to the open positionmaking any items or articles therein accessible to a user. From this view, retention components 105 and 106 may be better appreciated; although the individual retention ridges 105a, 105b, 106a, and 106b are also visible in FIG. 1, albeit disengaged. In the view of FIG. 2, wherein childproof box 100 is in the open position, retention ridges 105a, 105b, 106a, and 106b are in the engaged position (touching each other) to form retention components 105 and 106 to prevent rigid base shell 102 from being removed from the flexible cover shell 101.
(29) Opening or accessing a storage cavity of rigid base shell 102 is typically achieved by pressing and pushing on a portion of top surface 111 of flexible cover shell 101 (for example pressing serrated section 112 (see FIG. 4(a)) in order to disengage a pair of locking ridges 103a and 104a of rigid base shell 102 from a pair of corresponding locking ridges 103b and 104b (respectively) of flexible cover shell 101 that (respectively) form locking components 103 and 104. Disengaging these locking components allows rigid base shell 102 to slide open upon the user simultaneously pushing on flexible cover shell 101.
(30) Moreover, and as will be explained in more detail below with reference to FIG. 7, pressing down and pushing on top surface 111 of flexible cover 101 disengages each locking component 103 and 104 without misaligning the pair of retention ridges 105b and 106b of flexible cover shell 101 from the pair of corresponding retention ridges 105a and 106a of rigid base shell 102 (see for example FIG. 7), thereby retaining rigid base shell 102 partially within the cavity extending into flexible cover shell 101 from opening 110, as shown in FIG. 2. Since pressing down and pushing on top surface 111 of flexible cover shells 101 does not misalign retention ridges 105b and 106b from retention ridges 105a and 106b, these elements engage to form retention components 105 and 106 preventing rigid base shell 102 from being removed completely or disengaged from flexible cover shell 101.
(31) Turning next to FIG. 3, a perspective exploded view of childproof box 100 is illustrated. The exploded view better depicts each of the locking ridges 103a, 104a, 103b, and 104b protruding from side walls on their respective shells are visible. Similarly, this view better depicts each of the retention ridges 105a, 106a, 105b, and 106b protruding from side walls of their respective shells. It may also be noticed that each of retention ridges 105a, 106a, 105b, and 106b on their respective shells are situated along side walls at a height that is greater than a height of each of the locking ridges 103a, 104a, 103b, and 104b. Further, the ridges (locking and retention ridges) of flexible cover shell 101 are situated along interior side walls of flexible cover shell 101 protruding towards the interior cavity, while the ridges (locking and retention ridges) of rigid base shell 102 are situated along exterior or exterior side walls of rigid base shell 102, protruding towards the interior side walls of flexible cover shell 101.
(32) Turning now to the next set of figures, FIG. 4(a) illustrates a perspective view of flexible cover shell 101 of childproof box 100 in accordance with an exemplary embodiment of the present invention. More specifically, FIG. 4(a) depicts flexible cover shell 101, comprising top surface 111, front opening 110, a cover back wall (back wall 109; (see also FIG. 4(c)-(f))), and two cover side walls (side walls 107 and 108), which form an open cavity in-between that extends inward from front opening 110 towards back wall 109. Side walls 107 and 108 include tracks 113 and 114, which run a length along a bottom edge of an interior side surface of each cover side wall 107 and 108. Further, flexible cover shell 101 also comprises serrated section 112, which provides a user with friction to facilitate the pressing and sliding motion required to slide open rigid base shell 102 away from flexible cover shell 101 so as to access the storage cavity therein.
(33) FIG. 4(b) illustrates a front view of flexible cover shell 101. From this view, without rigid base shell 102, locking ridges 103b and 104b as well as retention ridges 105b and 106b may be seen protruding from the interior or interior side surface (of side walls 107 and 108) of cover shell 101. As may be appreciated from this view, the pair of retention ridges 105b and 106b of flexible cover shell 101 are situated along the interior side surface closer to an interior top surface 111a and above the pair of locking ridges 103b and 104b of flexible cover shell 101, so that retention ridges 105b and 106b are situated at a greater height (along a length of each side wall 107 and 108, respectively) than the height of locking ridges 103b and 104b. Moreover, the pair of locking ridges 103b and 104b are situated in proximity, or immediately adjacent to, tracks 113 and 114, respectively. Further, each of locking ridges 103b and 104b may have a height that is approximately less than half the height of the inner side surface of the corresponding side wall. Similarly, each of retention ridges 105b and 106b may have a height that is also approximately less than half the height of the inner side surface of the corresponding side wall. In exemplary embodiments, retention ridges 105b and 106b are smaller than (or have a height less than) a height of locking ridges 103b and 104b.
(34) FIG. 4(c) illustrates a back view of flexible cover shell 101, showing back wall 109 is generally flat and smooth without any protrusions or curvature, similar to side walls 107 and 108 as illustrated in the side view of FIG. 4(d). Similarly, top surface 111 is generally smooth (with the exception of serrated section 112), runs substantially parallel to bottom surface 121 of rigid base shell 102, and does not include a curvature other than (in exemplary embodiments) smoothed edges of corners 155 of flexible cover shell 101. In exemplary embodiments, the smooth edges and flat surfaces of flexible cover shell 101 make the device easy to hold and operate. Moreover, the flat smooth surfaces make the device easy to store in a pocket, and easy for a distributer, such as a shop, pharmacy, or supplier, to store in large inventory form.
(35) FIG. 4(e) illustrates a top view of flexible cover shell 101. Other than serrated section 112, top surface 111 is generally smooth and planar or flat. In exemplary embodiments, serrated section 112 may have printed instructions such that a user may read how to operate childproof box 100. Of course, in other embodiments serrated section 112 may not be implemented at all, without deviating from the scope of the present invention.
(36) FIG. 4(f) illustrates a bottom view of flexible cover shell 101, where it may be appreciated that the cover shell includes an interior top surface 111a (see also FIG. 4(b)) having a planar or flat surface excluding any protrusions or structures that may otherwise interfere with items or articles that may be stored using childproof box 100. Moreover, from the bottom view of the flexible cover shell, it may be appreciated that back wall 109 has an interior back surface 109a, which is also smooth and does not include any structures or protrusions that may interfere with or otherwise minimize the size of the cavity within flexible cover shell 101 (and thereby minimizing storage within childproof box 100). Further, tracks 113 and 114 may be seen extending from the front opening 110 and terminating at recesses 113a and 114a (respectively). This configuration of the underside of the cover shell forms or defines an aperture 119a formed between interior back surface 109a of back wall 109 and each of the tracks 113 and 114. As mentioned above, aperture 119a adds additional flexibility to flexible cover shell 101.
(37) FIG. 4(g) illustrates a cross-sectional view of flexible cover shell 101 taken along cross-sectional line B (in the direction of the arrows or towards interior back surface 109a of back wall 109). More specifically, from this view, it may be appreciated that the pair of retention ridges 105b and 106b or locking ridges 103b and 104b protruding from the interior side surface of the flexible cover shell 101 are not visible so that the visible portions of interior walls of side walls 107 and 108 are smoothin contrast with the front view of FIG. 4(b), or the cross-sectional view along line A (see FIG. 1) that will be discussed further below with reference to FIG. 6(a), FIG. 6(b), and FIG. 7. This is because the pair of retention ridges 105b and 106b are situated in proximity to the front opening 110 of flexible cover shell 101, and the pair of locking ridges 103b and 104b are situated substantially at the center or middle portion of the cover shell and slightly closer to opening 110 (to the right of cross-sectional line B) than to interior back wall 109a. Also from this view, the proportions of tracks 113 and 114 may be further appreciated, which are generally of a thickness enough to structurally grasp or register with rigid base shell 102 but not so thick that they interfere with a flexibility of flexible cover shell 101. As in the shown embodiment, tracks 113 and 114 are configured to support the side walls (117 and 118) of rigid base shell 102 in a manner such that a bottom portion (or corresponding tracks 122) of each of the base's side walls 117 and 118 rest along a length of each track 113 and 114, respectively.
(38) Turning now to the next set of figures, FIG. 5(a) illustrates a perspective view of a rigid base shell for childproof box 100 in accordance with an exemplary embodiment of the present invention. More specifically, FIG. 5(a) depicts rigid base shell 102, which in the shown exemplary embodiment comprises bottom surface 121, front wall 120, base back wall (back wall 119) and two base side walls (side walls 118 and 117), forming a closed cavity in-between. Each of side walls 117 and 118 have interior surfaces 115 and 116 respectively, and include corresponding tracks 122 formed by step ridges 123 and 124 (see FIG. 5(f)) that run along an entirety of a length of rigid base shell 102 between front wall 120 and back wall 119. Corresponding tracks 122 are configured to register with tracks 113 and 114 of flexible cover shell 101. As may be appreciated from this view, every interior wall or interior surface of front wall 120 and back wall 119 as well as bottom surface 121, side walls 117 and 118 (or their interior surfaces 115 and 116) are substantially smooth, free of any structures or mechanisms that may interfere with the space or cavity within rigid base shell 102 so that storage space is maximized.
(39) On each outer or exterior surface of side walls 117 and 118, locking ridges 103a and 104a that correspond to the locking ridges 103b and 104b of flexible cover shell 101 and retention ridges 105a and 106a that correspond to the retention ridges 105b and 106b of flexible cover shell 101 extend outwardly or protrude from the exterior surface.
(40) FIG. 5(b) illustrates a side view of rigid base shell 102, in accordance with an exemplary embodiment of the present invention. From this view, it may be appreciated that corresponding tracks 122 extend along a bottom edge of each side wall 117 and 118 from front wall 120 to back wall 119 of the rigid base shell 102. From this view, as well as from the view depicted by FIG. 5(a), it may be appreciated that the pair of corresponding retention ridges 105a and 106a protruding from the exterior side surface of the base side walls 117 and 118 of the rigid base shell 102 are situated in relative proximity to the base back wall 119. Moreover, from the side view of FIG. 5(b) as well as the front view of FIG. 5(c), it is noticeable that the pair of corresponding retention ridges 105a and 106a of the rigid base shell 102 are situated at a greater height along the exterior side surface than a height of the pair of corresponding locking ridges 103a and 104a of the rigid base shell 102. Furthermore, the pair of corresponding locking ridges 103a and 104a protrude from the exterior side surface of the base side walls 117 and 118 of the rigid base shell 102 along an edge (131 and 132, respectively) of the corresponding tracks 122.
(41) FIG. 5(d) illustrates a top view of rigid base shell 102 in accordance with an exemplary embodiment of the present invention. More specifically, FIG. 5(d) depicts exemplary configurations of locking ridges 104a and 103a and retention ridges 105a and 106a. In such exemplary embodiment, corresponding retention ridges 105a and 106a protrude from side walls 117 and 118 a length L.sub.1 from back wall 119 of rigid base shell 102. In such exemplary embodiment, corresponding locking ridges 103a and 104a protrude from side walls 117 and 118 a length L.sub.2 from back wall 119 of rigid base shell 102. Accordingly, each pair of corresponding retention ridges protruding from the exterior side surface of the base side walls of the rigid base shell are situated in proximity to the base back wall in relation to the corresponding locking ridges. Further still, from this view, it may be appreciated that the bottom surface 121 of the rigid base shell 102 is a flat surface excluding any protrusions.
(42) FIG. 5(e) illustrates a close-up view of retention protrusion 106a and locking protrusion 104a, in accordance with an exemplary embodiment of the present invention. From this view, it may be appreciated that the corresponding locking ridges 104a and 103a may have a greater length than a length of the corresponding retention ridges 105a and 106a and typically include gradual edges 125 and 126 respectively in order to facilitate entry into the cavity of flexible cover shell 101. Further, these components further include substantially perpendicular edges 127 and 128 which engage with corresponding components of the flexible cover shell (also substantially perpendicular) in order to retain or lock each shell in place. Although not shown in this figure, locking ridges have a greater length than a length of the retention ridges of flexible cover shell 101 and are generally similar to each other in construction in that they each protrude from a side wall of their respective shells. FIG. 5(f) illustrates a cross-sectional view of rigid base shell 102 taken along cross-sectional line C (in the direction of the arrows or towards back wall 119).
(43) Turning now to the next set of figures, FIG. 6(a) illustrates a cross-sectional exploded view of childproof box 100, taken along the line A (as shown in FIG. 1) in accordance with an exemplary embodiment of the present invention; similarly, FIG. 6(b) illustrates a cross-sectional view of childproof box 100. From this view, it may be appreciated that in an exemplary embodiment, a bottom exterior surface of the rigid base shell may sit slightly below the tracks of the flexible cover shell.
(44) Finally turning to the last figure, FIG. 7 illustrates a cross-sectional view of childproof box 100 in accordance with an exemplary embodiment of the present invention, depicting a method of operation. More specifically, from this view it may be appreciated that pressing down and pushing on the top surface 111 of flexible cover 101 disengages each locking component 103 and 104 without misaligning retention components 105 and 106, which remain engaged. That is the pair of retention ridges 105b and 106b of the flexible cover shell 101 stay engaged with the pair of corresponding retention ridges 105a and 106a of the rigid base shell 102, thereby retaining the rigid base partially within the open cavity of the flexible cover, when it is opened. Since pressing down and pushing on the top surface 111 of flexible cover 101 does not misalign retention ridges 105b and 106b from retention ridges 105a and 106a, retention components 105 and 106 prevent the rigid base shell 102 from being removed completely or disengaged from flexible cover shell 101.
(45) This may be achieved because cover 101 is constructed so that it is flexible and can bend sufficiently in order for the side walls to swing outwardly. However, they do not swing so outwardly as to misalign retention components 105 and 106. Similarly, base 102 is constructed so that it is rigid, which keeps corresponding locking ridges 103a and 104a as well as corresponding retention ridges 105a and 106a substantially stillmovement preferably only occurs at the side walls of the flexible cover.
(46) In exemplary practice, operating the present invention may be achieved with a single hand. For example, and without limiting the scope of the present invention, supposing a user holds childproof box 100 in their right hand, the user may support childproof box 100 between their right index finger and their right thumb of their right hand, their thumb placed over a center portion of childproof box 100for example over serrated section 112 of top surface 111 of childproof box 100. Using their right thumb, the user may press down as shown by direction F.sub.1 and push or slide their thumb in a forward direction along (for example) direction F.sub.2 shown in FIG. 2. In this manner, an adult user may easily operate childproof box 100 with a single hand.
(47) A childproof box has been described. The foregoing description of the various exemplary embodiments of the invention has been presented for the purposes of illustration and disclosure. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching without departing from the spirit of the invention.
