Definitions

  • a childproof safety package including a container having a spring member secured thereto with a cap engaging portion surrounding the discharge opening of the container, the cap engaging portion being yieldable along the container axis.
  • a plurality of container locking elements are located a fixed axial distance from the normal unstressed position of the cap engaging portion such that the cap engaging portion is resiliently yieldable toward the container locking elements from its normal position.
  • a safety cap is mounted on the container having a plurality of cap locking elements engageable with a disengageable from the container locking ele ments by combined axial and rotative motion of the cap relative to the container. and the cap engaging portion of the spring member engages the inner surface ofthe end wall ofthe cap when the locking elements are engaged to bias the cap against axial movement from locked engagement with the container.
  • CHILDPROOF SAFETY PACKAGE This invention relates generally to childproof safety packages and is particularly concerned with safety packages of the type having a cap that can be applied to and removed from its container only by combined axial and rotative motion.
  • Hedgewick U.S. Pat. No. 3,344,942 discloses a safety cap and container wherein a plurality of container-locking elements are spaced peripherally from each other on the outer wall of the mouth portion of the container for engagement with complementary cap-locking elements on the inner wall of the peripheral skirt projecting axially from the base of the cap.
  • the cap and container-locking elements are of the type wherein the cap must be engaged with and disengaged from the container by combined axial and rotative motion of the cap relative to the container.
  • the caplocking elements are biased against disengagement from the container-locking elements by a spring member in the form of an integral annular web formed on the cap.
  • An object of this invention is to provide a childproof safety package of the type in which a cap may be interlocked with and disengaged from a container only by combined axial and rotative motion of the cap relative to the container wherein biasing means is carried by the container for resiliently maintaining the cap in interlocked engagement with the container.
  • Another object is to provide a childproof safety package particularly suitable for liquid household products such as furniture polish, liquid cleansers, toiletries, and insecticides wherein the discharge opening of the container is surrounded by a cap-engaging portion which is yieldable along the axis of the container so as to provide a biasing force to bias a cap into locked engagement with the container.
  • Still another object is to provide a childproof safety package for liquid products such as furniture polish wherein it is desirable for the liquid to be dispensed through a small orifice either by shaking the container with the cap removed, or by squeezing a pliable container to cause liquid to be squirted through the dispensing orifice.
  • a further object is to provide a one-piece molded plastic spring member suitable for use with childproof safety packages wherein the spring member can be fixedly mounted on a container in such a manner that the spring member engages the safety cap when applied to the container to bias the safety cap into locked engagement with the container.
  • a further object is to provide a one-piece molded plastic spring member for safety packages that can be mounted on a container so that liquid contents of the container can be dispensed through an orifice in the spring member, and wherein the spring member reacts between the container and a safety cap applied thereto to maintain the cap and container in locked engagement with each other.
  • a plurality of container-locking elements are spaced peripherally from each other on the outer surface of the container and are located a fixed axial distance from the normal position of the cap-engaging portion of the spring member.
  • FIG. 1 is a sectional view of safety-dispensing apparatus embodying the present invention
  • FIG. 2 is an elevational view of the mouth portion of the container in the assembly of FIG. 1;
  • FIG. 3 is a top plan view of the container of FIG. 2.
  • a childproof safety package comprises a container 10 having a mouth portion 12 with a discharge opening 20 defined therein.
  • the mouth portion 12 projects upwardly from a radially outwardly extending flange 14.
  • Spring means designated generally by reference numeral 16 is secured to the container and includes a cap-engaging portion 19 surrounding the discharge opening 20.
  • the cap-engaging portion 19 is yieldable along the axis of container 10 from a normal, unstressed position illustrated in phantom lines in FIG. I at 16a.
  • a plurality of container-locking elements 18 are spaced peripherally from each other and are located a fixed axial distance from the normal position of the cap-engaging portion such that the cap-engaging portion I9 is resiliently yieldable toward the container-locking elements 18 from its normal position as indicated at 16a.
  • the container-locking elements 18 are of the type shown in the above-mentioned Hedgewick U.S. Pat. No. 3,344,942 and each includes a radially outwardly extending projection formed with a notch 22 formed between a stop portion 24 and a cam portion 26 (FIG. 2).
  • the childproof safety package of FIG. 1 further includes a cap 28 having an end wall 30 with a peripheral skirt 32 projecting axially therefrom for receiving the mouth portion 12 of the container. Spaced peripherally from each other on the inner surface of the skirt portion 32 is a plurality of caplocking elements 34 in the form of radially inwardly projecting lugs.
  • the cap-locking elements 34 are engageable with and disengageable from the container-locking elements 18 by an axial motion of the cap relative to the container followed successively by a rotative motion of the cap relative to the container. To apply the cap to the container, the cap-locking elements 34 are aligned with the spaces between the containerlocking elements 18 so that the locking lugs 34 engage the can surface of the cam portion 26 of the locking elements 18.
  • the cap-locking elements Upon rotation of the cap in the direction to move the caplocking elements 34 toward the left in FIG. 2, the cap-locking elements are cammed downwardly by the cam portion 26 until they engage the respective stop portion 24, at which point the lugs 34. come into alignment with the respective notches 22. Subsequent upward movement engages each cap-locking element 34 in a notch 22 to prevent relative rotation between the cap and container.
  • the cap-engaging portion 19 of spring member 16 engages the inner surface 36 of the end wall 30 of the cap when the locking elements 18 and 34 are engaged, as shown in FIG. 1, to bias the cap against axial movement from locked engagement with the container.
  • the cap-engaging portion 19 overlies the mouth of the container, and the discharge opening 20 is in the form of a dispersing orifice formed in the cap-engaging portion I9.
  • Extending from the end wall of the cap into the orifice is an integral axial projection 38 which acts to close the orifice 20 when the locking elements are engaged as well as to prevent clogging of the orifice.
  • Annular sealing elements 40 and 42 surround the projection 38 and the orifice 20. The sealing elements are engaged between the opposed surfaces of the cap end wall 36 and the cap-engaging portion 19 of spring member 16.
  • the annular sealing elements each comprise an axially projecting rib formed integrally on the cap-engaging portion 19.
  • Spring member 16 comprises a domelike body having a generally flat base portion which defines the cap-engaging portion 19, and yieldable means 44 supporting the base portion 19 in axially spaced relationship with respect to the container-locking elements 18.
  • Base portion 19 is supported by the yieldable means 44 in its normal position as indicated in phantom lines at 16a in the unstressed condition of the yieldable means, and is biased to return to the normal position 16a upon flexure of the yieldable means 44 when the cap is placed on the container as shown in FIG. 1.
  • the yieldable means 44 comprises a generally spherical wall portion integral with and curved outwardly and axially from the base portion 19 for reacting between the container and cap 28 to bias the cap toward locked engagement with the container.
  • Container 10 is formed with an annular rim 46, and the spring member 16 is formed with a rim-engaging portion 48 for securing the spring member 16 to rim 46.
  • the spherical wall portion 44 resiliently biases the rim-engaging portion 48 and cap-engaging portion 19 toward axially separated positions.
  • the rim-engaging portion 48 includes a radially outwardly extending flange 50 for overlying the container rim 46, flange 50 forming the upper portion of an annular groove 52 formed in the spring member 16. Groove 52 receives a complementary radially inwardly projecting annular rib 54 formed on the container adjacent rim 46.
  • the orifice 20 is tapered inwardly from the outer surface of the cap-engaging portion 19, and the projection 38 is tapered complementary with the orifice 20 as shown in H6. 1.
  • Ribs 40 and 42 are biased into contact with the inner surface 36 of the cap end wall 30 to provide a liquid seal.
  • the spring member 16 is thus in the form of a one-piece, molded plastic, dome-shaped body having a base portion 19 with a centrally located discharge opening formed therein.
  • An axially extending cylindrical mounting flange 48 has a diameter larger than the diameter of the base portion 19 for mounting the spring member on the rim 46 of the container, and a spherical wall portion 44 connects the periphery of the base portion 19 with the cylindrical mounting portion 48.
  • the spherical wall portion 44 is curved axially and outwardly from the base portion to the mounting flange 48 and yieldably maintains the base portion and mounting flange in axially separated positions.
  • the annular groove 52 formed on the mounting flange 48 is forced onto the annular projection 54 of the container to secure the spring member 16 to the container.
  • the cap is removed from the container by displacing the cap axially toward the rim 46 of the container until the caplocking lugs 34 are completely disengaged from the notches 22 of the respective container-locking elements 18.
  • the cap is then rotated to bring the cap-locking elements 34 out of registry with the container-locking elements and permit the caplocking elements 34 to pass axially between the containerlocking elements 18 as the cap is removed from the'container.
  • Liquid contents of the container 10 may then be dispensed through the orifice 20 either by shaking the container, or in the case of a pliable plastic construction for the container 10, liquid contents can be caused to squirt through the orifice 20 by squeezing the container.
  • Spring member 16 thus serves both as a biasing means to maintain the safety cap 28 in locked engagement with the container, and also to provide a dispensing outlet for liquid contents.
  • Suitable materials for the spring member are polypropylene, polyethylene, polystyrene, and other plastics.
  • the cap 28 may also be molded in one-piece from polypropylene, polystyrene, polyethylene and the like.
  • the illustrated container may also be blow-molded of polystyrene, polypropyiene polyethylene, or the like, although the cap and spring member may also be used with containers made of other materials.
