Abstract
A child-resistant closure for a container includes an inner cap retained in an outer cap, the outer cap being rotatable with respect to the inner cap; the inner cap having a gripping surface on a circumferential sidewall; the outer cap having a circumferential lateral wall defining elongate cutouts that expose the gripping surface, the cutouts being sized and spaced to provide adequate contact area between a typical thumb of an adult and the exposed gripping surface to allow removal of the closure from a container and inadequate contact area between a typical thumb of a child.
Description
- Not Applicable.
- This disclosure pertains to child-resistant packaging and more particularly to internally threaded caps or closures that are highly resistant to removal from a container by a child, but which can be easily removed by an elderly, weak or infirm adult.
- Child-resistant locking closures were invented in the 1960's, and have been widely used as a last line of defense against the risk of children ingesting dangerous materials. The Poison Prevention Packaging Act requires the use of child-resistant packaging for most prescription drugs, over-the-counter drugs, household chemicals, and other hazardous materials that could be dangerous for children.
- There are now hundreds of child-resistant packaging designs available. Most of these designs require two dissimilar motions for opening, which are intended to be easy for adults, yet difficult for children. However, the U.S. Consumer Product Safety Commission has stated that there is no such thing as child-proof packaging. Thus, the objective is to design packaging that denies access to most children, while allowing access to most adults. Existing child-resistant packaging is reasonably effective at preventing most children from opening such containers, while allowing most adults easy access to the contents of such containers. However, because most of these designs rely on a disparity between the knowledge, strength and/or dexterity of the typical adult as compared with the typical child, there are precocious and/or unusually strong or dexterous children that will be able to open existing child-resistant packaging, and there are weak, elderly or infirm adults that will be denied access to the contents of child-resistant packaging.
- Thus, there is a need for an improved child-resistant cap or closure for a container that allows fewer children to open the container and also allows more adults to open the container.
- The disclosed child-resistant internally threaded closure relies primarily, or at least in part, on a difference between adults and children other than knowledge, strength and/or dexterity. Rather, the disclosed child-resistant internally threaded closure relies on an anatomical differences between children and adults that is more reliable than the difference between the strength, knowledge and/or dexterity of children as compared with adults. In particular, the child-resistant closures described herein employ a design that takes advantage of the more consistent disparity between the width or surface area of the flesh covering the phalanges of fingers and thumbs of the typical adult as compared with those of the typical child. The fingers and thumbs are unique precision tools that apply grip force in a specific way that no other body parts or body surfaces can emulate to the same degree. The differences in bone size of the fingers and thumbs govern structural support for the surface area of the flesh to provide an adequate area of contact pressure coverage. The thumb provides the greatest area of contact pressure coverage. However, an adult with a sufficiently large index finger could open the cap by gripping with their index finger (although the thumb applies force more efficiently, making opening with the thumb feel easier). Throughout the remainder of this disclosure, reference will be made to application of gripping forces using the thumb. However, the disclosed design is not limited to the thumb disparity between adults and children, but instead applies to the fingers as well.
- The disclosed child-resistant closure has an inner cap retained in an outer cap. Gripping surfaces on a sidewall of the inner cap are exposed through cutouts in the outer cap. The cutouts are sized and spaced so that a thumb of a typical adult can contact an area of the gripping surface that is sufficient to provide the force needed to remove the closure from the container, whereas the thumb of a typical child is too small to contact a sufficiently large area of the exposed gripping surface to allow removal of the closure from the container.

FIG. 5 is a bottom perspective view of the outer cap of the child-resistant closure. -
FIG. 6 is an exploded perspective view showing threading engagement between the child-resistant closure and a container. - Shown in
FIG. 1 is a child-resistant closure 10 in accordance with this disclosure. Closure 10 includes an inner cap 12 (shown inFIGS. 2 and 3 ), and an outer cap 14 (shown inFIGS. 4 and 5 ). As shown inFIG. 1 ,inner cap 12 is nested within and retained byouter cap 14. -
Outer cap 14 includes alip portion 16 that extends radially inwardly of alateral wall 28 that depends from anupper wall 19. In the illustrated embodiment,lip portion 16 is located at a bottom edge ofwall 28, but could conceivably extend from aninterior side 29 ofwall 28 disposed in spaced relation to the bottom edge ofwall 28.Lip portion 16 retainsinner cap 12 withinouter cap 14 so that it cannot be easily separated from the outer cap when theclosure 10 is completely removed from a container. -
Inner cap 12 includes atop wall 41 and a dependingcircumferential side wall 20 having aninterior surface 21 provided withinternal threads 34 for engagingexternal threads 36 on a container 22 (seeFIG. 6 ), and anexterior surface 23 provided withgripping features 32. In the illustrated embodiment, gripping features 32 comprise a plurality of parallel elongate protuberances or ribs that extend vertically (i.e., parallel to the screw axis of cap 12), however, other types of gripping features can be employed, such as hemispherical bumps, knurls, or the like. - The
lateral wall 28 includes an upperelongate cutout section 24 and a lowerelongate cutout section 26 that is spaced from thecutout 24 and separated fromcutout 24 by abridge portion 30.Cutouts exterior surface 23 ofsidewall 20 ofinner cap 12. Thecutouts gripping features 32, whereas the thumb of a typical child would contact a substantially reduced area of the exposed gripping surfaces. Therefore, a child would need to apply substantially more thumb pressure in order to apply the amount of force needed to unscrewclosure 10 from acontainer 22. For example, a typical adult has a distal phalanx portion of the thumb that is about 30 mm long and about 20 mm wide, whereas a typical child might have a distal phalanx portion of the thumb that is about 25 mm by 15 mm. Thus, if thecutouts closure 10 from acontainer 22, a typical child would be required to apply more than twice the amount of pressure needed by the typical adult to remove the closure. Stated differently, an adult-size thumb can wrap around thebridge 30 to apply pressure and torque toinner cap 12, whereas a child-size thumb cannot wrap aroundbridge 30 to allow sufficient contact with the exposed gripping surface. - The amount of effort needed to open the
container 22 can be controlled by appropriate design of the threads (e.g., pitch, lead, thread angle, thread depth, etc.), and by providing the closure with astop 46 that prevents over-tightening ofclosure 10 onto acontainer 22.Stop 46 is located on theinterior surface 21 ofwall 20 ofinner cap 12, and includes a bottom orstop surface 47 that engages anupper edge surface 50 ofbottle 22 to ensure that the amount of torque or force needed to removeclosure 10 does not vary appreciably after it is tightened ontobottle 22. - In the illustrated embodiment,
inner cap 12 is provided with one-way ratchet ramps 40 on the upper surface oftop wall 41.Ramps 40 each include asloped surface 52 and astop surface 54.Outer cap 14 is provided with one-way ratchet ramps 42 onbottom surface 44 ofupper wall 19. Each oframps 42 includes asloped surface 56 and astop surface 58. In the illustrated embodiment, clockwise rotation ofouter cap 14 causesouter cap 14 andinner cap 12 to lock and rotate together when stopsurfaces outer cap 14 causescaps sloped surfaces outer cap 14 to rotate unless adequate pressure is applied to the surfaces ofinner cap 12 exposed throughcutouts - The above description is intended to be illustrative and not restrictive. Many embodiments and applications other than the examples provided would be apparent upon reading the above description. The scope of the invention should be determined with reference to the appended claims along with the full scope of equivalents to which such claims are entitled. It is anticipated and intended that future developments will occur, and that the disclosed systems and methods will be incorporated into such future embodiments.
- All terms used in the claims are intended to be given their broadest reasonable constructions and their ordinary meanings as understood by those knowledgeable in the technologies described herein unless an explicit indication to the contrary is made herein. In particular, use of the singular articles such as “a,” “the,” “said,” etc., should be read to recite one or more of the indicated elements unless a claim recites an explicit limitation to the contrary.
