The present invention relates generally to child safety container systems, and more specifically to push and turn child resistant container type enclosures.
Child safety container systems are used on containers that store substances which may be potentially dangerous, harmful or otherwise undesirable for children. The nature of such substances is quite wide ranging, including such things as medications, cleaning products, poisons, gas, bleach, and many others. They may also include substances which are deemed appropriate for adults, but not so for children, such as cosmetics, alcohol, and medicinal or recreational products.
The central theme of such child safety container systems is clear—prevent a child from opening the container while permitting an adult to do so at will. Often this simple premise can be frustrating, for many adults suffer from arthritis or ailments of stiffness and weakness such that it may be physically challenging for an adult to open the safety container. More simply stated, making the container difficult for a child often makes it difficult for the elderly or infirm.
One form of such safety containers is recognized as the push and turn enclosure or system. Essentially the user must push the cap and bottom together with sufficient force so as to engage some form of internal locking structure such that rotation of the cap and container relative to each other translates to rotation of the interlocking threads permitting the cap and container to be unscrewed from one another.
The prior art is riddled with an impressive array of such devices. Some, but certainly not all examples of such systems can be found in US Patent Publication 2009/0032486 to Brozell et al. for TWO-PIECE CHILD-RESISTANT CLOSURE AND PACKAGE, US Patent Publication 2016/0030285 to Miceli et al. for CHILD PROOF CLOSURE, U.S. Pat. No. 10,414,560 to Aryanpanah et al. for CHILDPROOF JAR.
These references have been identified as a specific representation set of such child safety container systems because they share a common thread, and shortcoming. In an effort to assist an adult in manipulating the cap each of these references teaches a plurality of ridges about the outer wall. In other words, the outer wall of the cap is highly textured, and uniformly so. This is clearly to provide a non-slip surface that may be easily grasped and held during the press and turn operation required to open the container. Helpful to the grasping hands of an adult, these ridges are equally helpful to the hands of a child.
In contrast to these device, US Patent Publication 2015/0298866 to Hagen for CONTAINER, and Design patent D781,151 to Lerman for JAR, appear to go too far in the other direction by providing an entirely smooth outer surface wall. While indeed avoiding the potentially helpful outer grasping surface of the above references, these smooth walled alternatives may go too far and once again present a significant dexterity challenge to some adults.
Hence there is a need for a method and system that is capable of overcoming one or more of the above identified challenges.
Our invention solves the problems of the prior art by providing a novel child safety container for push and turn enclosures with finger grips.
In particular, and by way of example only, according to at least one embodiment, provided is a push and turn child safety container including: an outer body characterized by: a first circular element bounded by a first circumferential wall extending normally away from the first circular element for a first distance, the distal end of the first circumferential wall having an inward lip; an inner surface of the first circular element providing a plurality of first ridges; an inner body characterized by: a second circular element bounded by a second circumferential wall extending normally away from the second circular element a second distance less than the first distance, an inner surface of the second circumferential wall having first threads; and an outer surface of the second circular element having a plurality of second ridges for temporarily engaging with the first ridges of the first circular element; wherein the inner body is structured and arranged to nest within the outer body and be retained by the inward lip, the inner body freely rotating within the outer body below the lip when the first ridges are not engaged with the second ridges; and a screw element characterized by: a circular first element having an outer circumferential wall having three generally equally spaced indents structured and arranged to receive a user's finger tips; and a threaded collar extending normally from the circular first element below the indents, the threaded collar structured and arranged to be disposed within the inner body and engage the first threads of the inner surface of the second circumferential wall to temporarily bind the screw element with the inner body, the threaded collar defining at least a portion of a storage space for the safety container.
In yet another embodiment, provided is a push and turn child safety container including: an outer body characterized by: a first circular element bounded by a first circumferential wall extending normally away from the first circular element for a first distance, the distal end of the first circumferential wall having a retainer; an inner surface of the first circular element providing a plurality first grippers; an inner body characterized by: a second circular element bounded by a second circumferential wall extending normally away from the second circular element a second distance less than the first distance; an inner surface of the second circumferential wall having a first screw threads; and an outer surface of the second circular element having a plurality of second grippers for temporarily engaging with the first grippers of the first circular element; wherein the inner body structured and arranged to nest within the outer body and be retained by the retainer, the inner body freely rotating within the outer body below the retainer when the first grippers are not engaged with the second grippers; and a screw element characterized by: a circular first element having an outer circumferential wall having three indents structured and arranged to receive a user's finger, the circumferential wall sections between the indents being substantially smooth; and a threaded circular wall extending normally from a circular first element below the indents, the threaded collar structured and arranged to be disposed within the inner body and engage the first threads of the inner surface of the second circumferential wall to temporarily bind the screw element with the inner body.
For yet another embodiment, provided is a screw element with finger grips for a push and turn child safety container having an outer body having a first circular element bounded by a first circumferential wall extending normally away from the first circular element for a first distance, the distal end of the first outer wall having a retainer with an inner body having a second circular element bounded by a second circumferential wall extending normally away from the second circular element a second distance less than the first distance with an inner surface of the second circumferential wall having a first screw thread, the inner body nested with in the outer body and retained by the retainer, including: a screw element characterized by: a circular first element having an outer circumferential wall having three indents structured and arranged to receive a user's finger, the circumferential wall sections between the indents being substantially smooth; and a threaded circular wall extending normally from a circular first element below the indents, the threaded collar structured and arranged to be disposed within the inner body and engage the first threads of the inner surface of the second circumferential wall to temporarily bind the screw element with the inner body, the threaded collar defining at least a portion of a storage space for the safety container.
Before proceeding with the detailed description, it is to be appreciated that the present teaching is by way of example only, not by limitation. The concepts herein are not limited to use or application with a specific child safety system with push and turn resistant enclosure. Thus, although the instrumentalities described herein are for the convenience of explanation shown and described with respect to exemplary embodiments, it will be understood and appreciated that the principles herein may be applied equally in other types of systems involving push and turn enclosure systems.
This invention is described with respect to preferred embodiments in the following description with reference to the Figures, in which like numbers represent the same or similar elements. Further, with respect to the numbering of the same or similar elements, it will be appreciated that the leading values identify the Figure in which the element is first identified and described, e.g., element 100 first appears in
Turning now to the figures, and more specifically
To facilitate the description of systems and methods for embodiments of SCFG 100, the orientation of SCFG 100 as presented in the figures is referenced to the coordinate system with three axes orthogonal to one another as shown in
As may be appreciated from the perspective view of
It will be appreciated that for at least one embodiment the outer circumferential wall 108 has a first height 114. It will also be appreciated that the outer body 104 has a second height 116, and that the second height 116 is at least about one-and-a-half (1.5) times greater the first height 114. For at least one embodiment, the second height 116 is at least twice the first height 114. Moreover, the second height 116 is pre-selected to facilitate easy grasping with or without an external roughing or gripping element being provided upon the outside of the outer body 104.
In contrast, the screw element 102 has a first height 114 sufficient to accommodate indents 110, but is also thin enough and provided with smooth wall sections 112 such that it may be challenging to firmly grip and rotate, absent placement of a user's finger and thumb tips within the indent 110.
As noted above, the elderly and infirm may have issues with dexterity and hand strength. In contrast to prior art systems that offer texturized, ridged, ribbed or other roughened outer surfaces to increase the opportunity for friction as between the user's fingers and the container, the indents 110 of SCFG 100 provide true abutment surfaces 118, further shown in
In other words, indents 110 receive lateral force from the user's finger tips to assist in rotation of the screw element 102 relative to the outer body 104. This lateral force as provided by the user's finger tips is achieved by indents 110 being structured and arranged provide abutment surfaces 118 to receive the finger tips (including thumb tip/side) of a typical adult. More specifically, the indents 110 permit a user to push against surfaces to drive rotation as opposed to relying upon friction between the user's fingers and the outer surface to induce rotation.
Moreover, to provide indents 110 with sufficient size and abutment surfaces to receive a user's finger tips, for at least one embodiment each indent 110 has a length 120 of between about 1 centimeter and 2 centimeters, a depth 122 of between about 0.25 centimeters and 0.75 centimeters, and a height 124 of between about 0.25 centimeters and 0.75 centimeters. More specifically, for at least one embodiment each indent is about 1.5 centimeters in length 120, 0.5 centimeters in depth 122 and 0.5 centimeters in height 124.
The disposition of three indents 110 advantageously permits a user's thumb, first and second fingers to easily and naturally engage with the indents 110 and advantageously achieve an improved grip and ease of rotation. As used herein “fingertip” is understood and appreciated to include the thumb tip and or side of the thumb proximate to the thumb tip as well as the tip and/or side proximate to the tip of any finger.
A recent safety test conducted over the dates Jan. 13-24, 2021 in accordance with US 16 CFR § 1700.20 and recorded as Report No.: B-5210134471 by Beide Compliance Laboratory, was performed with fifty (50) children between the ages of 3.5 years and 4.25 years, and fifty (50) adults between the ages of 50 years and 70 years, found that adults were able to quickly realize the advantageous nature of the indents 110 of SCFG 100 to facilitate opening while the children were not.
Indeed, even when the children were shown where and how to place their fingers and thumb, the 49 of the 50 were still unable to repeat the demonstrated behavior and open the SCFG 100. Moreover, the physical difference in hand size and differences in developed visual acuity permits improved use of SCFG 100 by adults while SCFG 100 still advantageously provides a challenge to children.
With respect to
The inner surface 214 of the first circular element 202 has a plurality of first grippers 216 (See
As noted, the SCFG 100 also has an inner body 200 structured and arranged to nest within the outer body 104. The inner body 200 has a second circular element 218 (e.g., a top) bounded by a second circumferential wall 220 extending normally away from the second circular element 218 for a second distance 222 that is less than the first distance 206. The inner surface 224 of the second circumferential wall 220 has first screw threads 226.
The inner body 200 is structured and arranged to nest within the outer body 104 and be retained by the retainer 210. It will further be appreciated that the inner body 200 is structured and arranged to freely rotate within the outer body 104 and below the retainer 210, unless or until a user provides a sufficient press force upon the inner body 200 and the outer body 104 to achieve a temporarily locking or binding relationship as between the inner body 200 and the outer body 104.
This temporary locking or binding relationship is achieved by a temporarily engaging the first grippers 216 with the second grippers 230. Free rotation of the inner body 200 occurs within the outer body 104 and below the retainer 210 when the first grippers 216 are not engaged with the second grippers 230.
For yet another embodiment, the first grippers 216 are a plurality of notches with upward oriented openings, and the second grippers 230 are a plurality of ridges correspondingly sized and spaced to engage with the notches. It will be appreciated that the notches may be formed as structures depressed into the inner surface 214 of the first circular element 202, or defined by walls/ridges rising from the inner surface 214 to define a notch, or plurality of notches as between the raised walls/ridges.
For at least one embodiment, the first grippers 216 are a plurality of raised ridges, and the second grippers 230 are a plurality of notches with downward oriented openings correspondingly sized and spaced to engage with the plurality of ridges. It will be appreciated that the notches may be formed as structures depressed into the outer surface 228 of the second circular element 218, or defined by walls/ridges rising from the outer surface 228 to define a notch, or plurality of notches as between the raised walls/ridges.
Moreover, for at least one embodiment the first grippers 216 and the second grippers 230 are each provided as corresponding ridges which are correspondingly sized and disposed upon the inner surface 214 of the outer body 104 and the outer surface 228 of the inner body 200 to temporarily engage when the inner body 200 and outer body 104 are pressed together. For yet another embodiment the first grippers 216 and the second grippers 230 are substantially paired sets of bumps and indents. For still yet another embodiment the first grippers 216 and the second grippers 230 are correspondingly angled with respect each other to deflect engagement by rotation without a press fitting force applied simultaneously.
For at least one embodiment, at least one spring element 232 may be disposed between the inner body 200 and the outer body 104 to facilitate a non-locking/non-binding state as between the first grippers 216 and the second grippers 230 when the SCFG 100 is at rest. In varying embodiments, spring element 232 may be a coiled spring or a resilient material that may be temporarily compressed when a load is applied such as rubber/foam/bent wire/or the like, or such other element as is deemed appropriate for providing separation between the inner body 200 and the outer body 104 until such time as a user applies appropriate force to induce the temporary engagement as between the first grippers 216 and the second grippers 230. For at least one embodiment, the at least one spring element 232 may be incorporated as part of the inner surface 214 of the outer body 104 and the outer surface 228 of the inner body 200.
Screw element 102 may also be appreciated to have a threaded collar 234 extending normally from the circular first element 106 below the indents 110. The threaded collar 234 provides second screw threads 236 which are structured and arranged to engage with first screw threads 226 of the inner body 200. More specifically, the threaded collar 234 is structured and arranged to be disposed within the inner body 200 and to engage with the first screw threads 226 of the inner surface 224 of the second circumferential wall 220 to temporarily bind the screw element 102 with the inner body 200.
As an embodiment of SCFG 100 may be provided with the screw element 102 providing both the hollow area 238 for storage as well as the intended element to be grasped by a user and twisted while pressed against the nested inner body 200 and outer body 104, the terms of “cap” and “base” have not been specifically used herein so as to avoid a possible misperception of roles provided by these elements. In addition, the terms “top” and “bottom” as used herein are intended as terms of convenience in describing views and orientations, which may be interchanged. For ease of discussion, it may be generally be understood that for at least some embodiments the screw element 102 is essentially a jar—a wide mouth container providing product storage, and nested inner body 200 and outer body 104 provide the cap, or lid.
It is to be understood and appreciated that for at least one embodiment of SCFG 100, the engagement between the threaded collar 234 and the inner body 200 is substantially water tight. For yet another embodiment, one or more vent holes (not shown) may be disposed within the inner body in fluid connection to the outer body 104 such that vapor may escape from the hollow area 238 when the threaded collar 234 is engaged with the inner body 200.
In addition, as originally presented with respect to the description of
For at least one embodiment, the outer surface 900 of second circumferential wall 220 and the inner surface 1000 of first circumferential wall 108, may have optional one-way binders—elements 902 in
With respect to SCFG 100 as herein described, it will be understood and appreciated that the screw element 102, outer body 104 and inner body 200 may be formed of glass, ceramic, polycarbonate, metal, wood, or such other durable material as may be desired for varying embodiments. Indeed, in varying embodiments one or more of the elements may be made from different materials, e.g., the screw element may be formed of ceramic material while the outer body 104 and inner body 200 are formed of plastic or polycarbonate.
With respect to the above description and accompanying figurers, it will be appreciated that for at least one embodiment, SCFG 100 may be summarized as comprising: an outer body 104 characterized by: a first circular element 202 bounded by a first circumferential wall 204 extending normally away from the first circular element 202 for a first distance 206, the distal end of the first circumferential wall 204 having an inward lip 212; an inner surface 214 of the first circular element 202 providing a plurality of first ridges; an inner body 200 characterized by: a second circular element 218 bounded by a second circumferential wall 220 extending normally away from the second circular element 218 a second distance 222 less than the first distance 206, an inner surface 214 of the second circumferential wall 220 having first threads 236; and an outer surface of the second circular element 218 having a plurality of second ridges for temporarily engaging with the first ridges of the first circular element 202; wherein the inner body 200 is structured and arranged to nest within the outer body 104 and be retained by the inward lip 212, the inner body 200 freely rotating within the outer body 104 below the lip 212 when the first ridges are not engaged with the second ridges; and a screw element 102 screw element 102 characterized by: a circular first element 106 having an circumferential wall 108 having three generally equally spaced indents 110 structured and arranged to receive a user's finger tips; and a threaded collar 234 extending normally from the circular first element 106 below the indents 110, the threaded collar 234 structured and arranged to be disposed within the inner body 200 and engage the first threads 236 of the inner surface 214 of the second circumferential wall 220 to temporarily bind the screw element 102 with the inner body 200, the threaded collar 234 defining at least a portion of a storage space for the safety container 100.
For yet another embodiment, SCFG 100 may be summarized as comprising: an outer body 104 characterized by: a first circular element 202 bounded by a first circumferential wall 204 extending normally away from the first circular element 202 for a first distance 206, the distal end of the first circumferential wall 204 having a retainer 210; an inner surface 214 of the first circular element 202 providing a plurality first grippers 216; an inner body 200 characterized by: a second circular element 218 bounded by a second circumferential wall 220 extending normally away from the second circular element 218 a second distance 222 less than the first distance 206; an inner surface 214 of the second circumferential wall 220 having a first screw threads; and an outer surface of the second circular element 218 having a plurality of second grippers for temporarily engaging with the first grippers 216 of the first circular element 202; wherein the inner body 200 structured and arranged to nest within the outer body 104 and be retained by the retainer 210, the inner body 200 freely rotating within the outer body 104 below the retainer 210 when the first grippers 216 are not engaged with the second grippers; and a screw element 102 characterized by: a circular first element 106 having an circumferential wall 108 having three indents 110 structured and arranged to receive a user's finger, the circumferential wall sections 112 between the indents 110 being substantially smooth; and a threaded circular wall extending normally from a circular first element 106 below the indents 110, the threaded collar 234 structured and arranged to be disposed within the inner body 200 and engage the first threads 236 of the inner surface 214 of the second circumferential wall 220 to temporarily bind the screw element 102 with the inner body 200.
It will also be appreciated that the advantageous screw element 102 with finger grips for a push and turn child safety container (e.g. SCFG 100) may be summarized as comprising: a circular first element 106 having an circumferential wall 108 having three indents 110 structured and arranged to receive a user's finger, the circumferential wall sections 112 between the indents 110 being substantially smooth; and a threaded circular wall extending normally from a circular first element 106 below the indents 110, the threaded collar 234 structured and arranged to be disposed within the inner body 200 and engage the first threads 236 of the inner surface 214 of the second circumferential wall 220 to temporarily bind the screw element 102 with the inner body 200, the threaded collar 234 defining at least a portion of a storage space for the safety container 100.
