Definitions

  • the application relates to a lightweight container closure or cap, and in particular to a container closure having a child-resistant safety feature to inhibit opening of the container by a child.
  • Child-resistant container closures are known in the art. Such closures typically have a nested two-cap construction, including a base cap for sealing a container opening and a cover cap that captures the base cap. The base cap threads onto a neck of the container about the opening. Cooperating features disposed on an inner portion of the cover cap and an outer portion of the base cap enable selective engagement between the base cap and the cover cap, such that a single rotational action is sufficient to install the closure onto the container while a combined rotational and pushing and/or squeezing action is required to remove the closure from the container.
  • the cover cap and the base cap reliable engage and rotate in tandem, but when the cover cap is rotated in second a direction so as to unthread the base cap from the container neck, the cover cap must be further manipulated (e.g., by pushing downward on the cover cap or squeezing a portion of the cover cap while rotating) to cause the base cap to rotate in tandem with the cover cap. If the cover cap is rotated in the second direction without further manipulating the cover cap, the closure the closure will not open the container.
  • GB2138410 discloses a two-piece closure with a cover cap and a base cap.
  • the base cap includes internal threads for engaging with threads on the neck of a container.
  • the cover cap includes a skirt that overlies the base cap and that includes a lower ring which engages with an outwardly projecting bead on the base cap for securing the cover cap to the base cap.
  • a top surface of the base cap includes vertical pawl projections that engage with downwardly projecting ratchets. The combination of the pawl and ratchets provide a clicking sound and bias the caps apart.
  • WO 98/22362 discloses a two-piece child-resistant closure.
  • the closure includes a cover cap and a base cap.
  • the base cap includes internal threads for engaging with threads on the neck of the container.
  • the cover cap includes a skirt that overlies the base cap and that includes a lower lip that engages with an outwardly projecting flange for securing the cover cap to the base cap.
  • a top surface of the base cap includes vertical castellations that engage with downwardly projecting castellations formed on the cover cap for removing the closure from the container. Fingers project down from the cover cap and engage with ramps on the base cap for providing a clicking sound as one cap rotates relative to the other.
  • a child-resistant container closure includes a base cap and a cover cap.
  • the base cap has a top and a skirt depending downwardly from the top, the skirt including a plurality of formed in an outer wall of the skirt below the top, internal threads for engaging a neck of the container, and a bottom end.
  • the cover cap has a top with a central opening and a skirt depending downwardly from the top, the top including a plurality of asymmetric downwardly extending teeth adjacent to the skirt, the skirt having a plurality of interspersed vertical legs each spaced apart from adjacent legs by vertical openings, the legs being joined at or near a bottom end of the skirt by a support ring.
  • the cover cap teeth are adapted for engagement with the base cap teeth.
  • the cover cap teeth When the cover cap is rotated in a first (locking) direction, the cover cap teeth engage the base cap teeth to cause the base cap to rotate along with the cover cap in a direction to tighten the base cap onto a container.
  • the cover cap teeth When the cover cap is rotated in a second (opening) direction in combination with a predetermined downward force urging the cover cap top toward the base cap top, the cover cap teeth engage the base cap teeth to cause the base cap to rotate along with the cover cap in a direction to loosen the base cap from the container.
  • the base cap teeth each have a sloped sliding face to ensure that one of the cover cap teeth will drop into a notch between adjacent base cap teeth when the cover cap is rotated in the second direction.
  • the base cap When the cover cap is rotated in the second direction in the absence of the predetermined downward force, the base cap remains nonrotating and the cover cap teeth slide over the base cap teeth causing an audible clicking sound as pairs of teeth jump from one sliding engagement to another.
  • a child-resistant container closure in another embodiment, includes a base cap and a cover cap.
  • the base cap has a top and a skirt depending downwardly from the top, the skirt including a plurality of asymmetric teeth recessed below the top, internal threads for engaging a neck of the container, and a bottom end.
  • Each of the base cap teeth has a closing face sloped about 20 degrees from vertical, an opening face sloped about 30 degrees from vertical, and a sliding face disposed between the closing face and the sliding face and sloped about 6 degrees from horizontal, a junction between the closing face and the sliding face being disposed above a junction between the opening face and the sliding face.
  • the cover cap has a top with an central opening and a skirt depending downwardly from the top, the top including a plurality of asymmetrical downwardly extending teeth adapted for engagement with the base cap teeth, the skirt having bottom end, an inwardly protruding raised ridge for centering the cover cap on the base cap, and a support ring protruding radially inwardly from the bottom end to engage with a ridge protruding radially outwardly from the bottom end of the base cap skirt to inhibit removal of the cover cap from the base cap.
  • Each of the cover cap teeth has a closing face sloped about vertical, an opening face sloped about 45 degrees from vertical, and a sliding face disposed between the closing face and the sliding face and sloped about horizontal.
  • the cover cap teeth When the cover cap is rotated in a first (locking) direction, the cover cap teeth engage the base cap teeth to cause the base cap to rotate along with the cover cap in the first direction to tighten the base cap onto a container.
  • the cover cap teeth When the cover cap is rotated in a second direction in combination with a predetermined downward force urging the cover cap top toward the base cap top, the cover cap teeth engage the base cap teeth to cause the base cap to rotate along with the cover cap in the second direction to loosen the base cap from the container.
  • the slope of the sliding faces of the base cap teeth ensures that one of the cover cap teeth will drop into a notch between adjacent base cap teeth when the cover cap is rotated in the second direction.
  • the closure 10 is a two-piece device including a cover cap 100 and a base cap 200.
  • the base cap 200 is designed to seal a container opening by threading onto a neck of the container.
  • the cover cap 100 is designed to snap around and capture the base cap 200, as depicted in Figs. 1 and 4 , and as is described in detail below.
  • the cover cap 100 includes a top 110 and a skirt 120 depending downwardly from a periphery of the top 110.
  • the top 110 has a centrally disposed opening 112 to reduce the amount of material required to make the cover cap 100, which also reduces the shipping weight of the closure 10.
  • the skirt 120 extends from a top end adjoining the top 110 to a bottom end 126.
  • the skirt 120 has a plurality of interspersed vertical legs 122 and vertical cut-outs or openings 124.
  • the legs 122 and the openings 124 preferably alternate in a regular pattern and the legs 122 are preferably joined together at a bottom end 126 of the skirt 120 by a support ring 128.
  • the support ring 128 provides rigidity to the skirt 120 while the openings 124 enable the skirt 120 to be lighter in weight and to use less material than a conventional solid skirt.
  • the skirt 120 further includes an inwardly protruding raised ridge 116 on each of the legs 122 to center the cover cap 100 on the base cap 200.
  • the interspersed legs 122 and slots 124 provide a good gripping surface for a user, particularly for a user with arthritis, advanced age, or other condition that limits gripping strength.
  • the base cap 200 includes a top 210 and a skirt 220 depending downwardly from a periphery of the top 210.
  • the skirt 220 extends from a top end adjoining the top 210 to a bottom end 224.
  • Internal threads 222 protrude inwardly from the skirt 220 for engagement with a container neck.
  • the base cap 200 has an outer diameter and the cover cap 100 has an inner diameter, the outer diameter of the base cap 200 being sufficiently smaller than the inner diameter of the cover cap 100 to create an annular gap 300, as shown in Fig. 4 .
  • the raised ridge 116 on each of the legs 122 is sized to be slightly smaller than the annular gap 300 to center the cover cap 100 on the base cap 200 while still allowing the cover cap 100 to rotate freely about the base cap 200 with minimal frictional interference with the base cap 200, such that contact between the raised ridges 116 and the base cap skirt 220 does not provide enough friction by itself to cause the base cap 200 to rotated when the cover cap 100 is rotated.
  • a plurality of cover cap teeth 130 extend downwardly from the top 110 of the cover cap 100 adjacent to and preferably formed integrally with the skirt 120.
  • the teeth 130 are circumferentially spaced apart at a regular spacing distance.
  • each tooth 130 is preferably formed on an inside surface of a leg 122, thus helping to stiffen the leg 122 when it attaches to the top 110.
  • Each tooth 130 is shaped with an asymmetric bias, having a sliding face 136, a closing face 132 disposed on one side of the sliding face 136, and an opening face 134 disposed on an opposite side of the sliding face 136.
  • a junction between the closing face 132 and the sliding face 136 forms a right angle or an obtuse angle, and a junction between the opening face 134 and the sliding face 136 forms an obtuse angle.
  • the sliding face 136 is preferably sloped in a range of about horizontal to about 5 degrees from horizontal, sloping downward from the junction with the closing face 132 to the junction with the opening face 134. In the depicted embodiment, the sliding face 136 is disposed at about horizontal.
  • the closing face 132 is preferably sloped in a range of about vertical to about 10 degrees from vertical. In the depicted embodiment, the closing face 132 is about vertical.
  • the opening face 134 is preferably sloped in a range of about 35 degrees to about 55 degrees from vertical.
  • each cover cap tooth 130 can include a recessed rear notch 114.
  • a plurality of base cap teeth 230 are formed in an outer wall of the skirt 220 of the base cap 200, the teeth 230 and are preferably located below the top 210. A portion 222 of the skirt 220 is recessed from the teeth 230.
  • the teeth 230 are circumferentially spaced apart at a substantially equal distance, the positioning of the teeth 230 of the base cap 200 substantially corresponding to the positioning of the teeth 130 of the cover cap 100 to enable engagement or meshing between the teeth 130, 230.
  • the number of teeth 130 and the number of teeth 230 need not be the same, but are preferably multiples of each other.
  • the cover cap 100 can be rotated no more than about 30 degrees (or one-twelfth of a rotation) relative to the base cap before engaging the base cap 200.
  • the number of teeth 130 and the number of teeth 230 can be selected to achieve the desired amount of free play between the cover cap 100 and the base cap 200 and the required engagement force between the sets of teeth 130, 230.
  • each base cap tooth 230 is shaped with an asymmetric bias, having a sliding face 236, a closing face 232 rising from a base 238 and disposed on one side of the sliding face 236, and an opening face 234 rising from an adjacent base 238 and disposed on an opposite side of the sliding face 236.
  • a junction between the closing face 232 and the sliding face 236 forms a right angle or an obtuse angle, and a junction between the opening face 234 and the sliding face 236 preferably forms an obtuse angle.
  • the sliding face 236 can be sloped in a range of about 2 degrees to about 10 degrees from horizontal, sloping downward from an apex 240 at the junction with the closing face 232 to a lower apex 242 at the junction with the opening face 234. In the depicted embodiment, the sliding face 236 is disposed at about 6 degrees from horizontal.
  • the closing face 232 can be sloped in a range of about vertical to about 20 degrees from vertical. In the depicted embodiment, the closing face 232 is at about 20 degrees from vertical.
  • the opening face 234 can be sloped in the range of about 20 degrees to about 45 degrees from vertical. In the depicted embodiment, the opening face 234 is sloped at about 30 degrees from vertical.
  • the base cap teeth 230 are preferably recessed into the outer wall of the base cap skirt 220.
  • the asymmetry of the cover cap teeth 130 and the base cap teeth 230 enables the teeth 130, 230 to engage more positively in a first, tightening or closing direction of rotation (typically clockwise for right-handed threads) than in a second, loosening or opening direction of rotation (typically counter-clockwise for right-handed threads).
  • a purpose of the closure 10 is to inhibit opening thereof by a child
  • the teeth 130, 230 engage in a way so as to bias the closure 10 to be closed with ease but opened with more difficulty, the closing operation requiring mere turning of the cover cap 100 in the first direction whereas the opening requiring a combination of urging the cover cap 100 downward toward the base cap 200 with a predetermined force and simultaneously rotating the cover cap 100 in the second direction.
  • the closing face 232 of the base cap teeth 230 can be undercut with respect to the base cap skirt 220, and the closing face 132 of the cover cap teeth 130 can be undercut with respect to the cover cap skirt 120. Accordingly, when the undercut faces 132 and 232 engage with each other, the rotational force applied to the cover cap 100 is partially directed to drawing the cover cap skirt 120 toward the base cap skirt 220, and the undercut cases 132, 232 are substantially locked together to inhibit jumping or stripping of the teeth 132, 232 during rotation.
  • the closing face 132 of the cover cap tooth 130 drops into the recess defined by the shape of the base cap teeth 230 and comes into contact and engages with the closing face 232 of the base cap tooth 230 in a manner that substantially prevents further rotation of the cover cap 100 with respect to the base cap 200.
  • the sloped sliding face 236 of the base cap tooth 230 ensures that the tooth 130 will drop into a notch between adjacent teeth 230 and that the closing faces 132, 232 of the respective teeth 130, 230 will engage, even if the speed of rotation of the cover cap 100 is fast. Without a sloped sliding face 236, it is possible that the teeth 130, 230 could skip or jump over each other without engaging when the cover cap 100 is rotated quickly in the first direction.
  • the opening face 134 of the tooth 130 comes into contact with the opening face 234 of the tooth 230 and the opening faces 134, 234 frictionally and slidably engage with each other.
  • This safety feature prevents the closure 10 from being opened by the mere turning of the cover cap 100 in the second direction but enables the closure 10 to be opened by a combination of simultaneously turning the cover cap 100 in the second direction while urging the cover cap 100 toward the base cap 200 with the predetermined force.
  • an audible clicking sound is emitted each time the teeth 130, 230 jump into a new contact between the opening faces 134, 234.
  • the audible clicking sound serves two purposes. First, it reminds a user that the closure 10 is a child-resistant cap and that a more complex pushing and rotating action is required to open the closure 10. Second, it provides an audible alert to an adult in the event a child is attempting to open the closure 10.
  • a particular advantage of the closure 10 is that the openings 124 in the skirt 120 and the opening 112 in the top 110 permit the clicking sound made by the releasing of the teeth 130, 230 from each other to more readily escape from within the cover cap 100, thereby making the sound louder and more audible by a user or an adult responsible for the safety of a child.
  • the cover cap 100 and the base cap 200 are held together to form the closure 10, such that the cover cap 100 is rotatable with respect to the base cap 200 but the cover cap 100 is not readily removable from the base cap 200. Capturing the base cap 200 within the cover cap 100 in this manner prevents a child from circumventing the safety features of the closure 10 by simply removing the cover cap 100 to directly rotate the base cap 200.
  • a rim on the cover cap support ring 128 protrudes radially inwardly from the bottom end 126 of the skirt 120 to bridge the gap 300, such that when the cover cap 100 is installed over the base cap 200, the support ring 128 is beneath the bottom end 224 of the base cap skirt 220.
  • the support ring 128 will contact the bottom end 224 of the base cap skirt 220 and prevent removal of the cover cap 100. It is understood, however, that the cover cap skirt 120 and the support ring 128, as well as the base cap skirt 220, are sufficiently flexible that if a large enough force and/or a skewed force is applied when attempting to lift the cover cap 100, the cover cap 100 can be forcibly removed from the base cap 200.
  • the bottom end 224 of the base cap skirt 200 can also include a raised ridge 226 protruding outwardly therefrom for engagement with the support ring 128.
  • the openings 124 in the cover cap skirt 120 can be sized to be sufficiently small so as to prevent a child's fingers from directly accessing and turning the base cap 200 without having to rely on the engagement between the cover cap 100 and the base cap 200 to open the closure 10.
