Definitions

  • U.S. Patent 4,997,096 discloses a child-resistant closure having inner and outer plastic shells.
  • the outer plastic shell has a base wall, a peripheral skirt and a circumferential array of lugs on an undersurface of the base wall.
  • the inner plastic shell has a base wall, a peripheral skirt, at least one internal thread segment on the skirt, and a circumferential array of lugs on an outer surface of the base wall for opposed engagement by the internal lugs on the base wall of the outer shell.
  • the outer shell To remove the closure when it is threaded onto a container neck finish, the outer shell must be pushed axially against the inner shell and simultaneously rotated so that the lugs on the outer shell engage the lugs on the inner shell and rotate the inner shell with respect to the container neck finish.
  • Each of the L-shaped lugs includes a first portion extending radially inwardly along an undersurface of the base wall of the outer shell for engaging the external lugs on the inner shell, and a second portion extending axially along an inner surface of the peripheral skirt of the outer shell for slidably engaging the inner shell and aligning the inner shell within the outer shell.
  • the second portions of the L-shaped lugs preferably have rounded radially inwardly facing surfaces for reduced sliding friction with the skirt of the inner shell.
  • the internal lugs on the outer shell and the external lugs on the inner shell may have opposed rounded axially facing surfaces such that the internal lugs on the outer shell cannot rest on the external lugs of the inner shell upon application of force to the outer shell.
  • the base wall of the outer shell may have a peripheral portion of a first thickness on which the internal lugs are disposed and an imperforate central portion of a second thickness less than the first thickness.
  • the base wall of the inner shell may have a peripheral portion of a third thickness on which the external lugs are disposed and an imperforate central portion of a fourth thickness less than the first thickness. The thinner central portions of the inner and outer shell reduce the weight and cost of the closure.
  • a child-resistant closure in accordance with another aspect of the present disclosure includes a plastic outer shell having an outer base wall with an outer peripheral portion and an outer central portion disposed within the outer peripheral portion.
  • the outer shell also has an outer peripheral skirt extending from the outer peripheral portion, and a plurality of internal lugs disposed at least in part on the outer peripheral portion.
  • a plastic inner shell of the closure has an inner base wall with an inner peripheral portion and an inner central portion disposed within the inner peripheral portion.
  • the inner shell also has an inner peripheral skirt extending from the inner peripheral portion, at least one internal thread segment on the inner peripheral skirt, and a plurality of external lugs disposed at least in part on the inner peripheral portion of the inner base wall adjacent to the inner peripheral skirt for engaging the internal lugs of the outer shell.
  • At least one of the central portions of the base walls has an array of ribs substantially equal in thiclaiess to its corresponding peripheral portion.
  • a child-resistant closure in accordance with a further aspect of the disclosure includes a plastic outer shell including an outer peripheral skirt, and an outer base wall from which the outer peripheral skirt depends and having a plurality of internal lugs adjacent to the outer peripheral skirt.
  • a plastic inner shell of the closure is disposed within the outer shell and includes an inner peripheral skirt with at least one internal thread segment, and an inner base wall from which the inner peripheral skirt depends and having a plurality of external lugs adjacent to the inner peripheral skirt.
  • the ribs 96 generally extend in a lateral direction from the peripheral portion 80 toward the central portion 82, wherein radially outer edges of one or more of the ribs 96 are contiguous with the peripheral portion 80. More specifically, the ribs 96 may be arranged in a spokelike pattern and, thus, may extend in a radial direction from the peripheral portion 80 to the center of the inner shell 42 or to the hub 98. In a preferred embodiment, however, and as shown in FIG. 8, there may be the same quantity of lugs 84 as there are ribs 96, and the ribs 96 may be generally radially aligned with the lugs 84.

Abstract

L'invention porte sur une coque en plastique (42 ou 44) pour une fermeture à l'épreuve des enfants à deux éléments de type pousser et tourner, laquelle coque comprend une jupe périphérique (48 ou 76), et une paroi de base (46 ou 74) à partir de laquelle la jupe périphérique s'étend. La paroi de base a une partie périphérique (50 ou 80) ayant une première épaisseur, une pluralité de crans (58 ou 84) disposés au moins en partie sur la partie périphérique adjacente à la jupe périphérique, et une partie centrale (52 ou 81) ayant une deuxième épaisseur inférieure à la première épaisseur. Une pluralité de nervures (66 ou 84) ayant une troisième épaisseur supérieure à la deuxième épaisseur et sensiblement égale à la première épaisseur s'étendent à partir de la première partie périphérique vers un centre de la paroi de base.
