  • Some containers have closures of the slip-over type wherein the closure is removed from the container or closed thereon by slipping it in a longitudinal direction relative to the container neck. Turning of the closure by a screwthreaded connection is not required. In such type of container, the same principle is also employed. However, instead of spaced abutments, the container is provided with an outwardly extending flange and the closure has radially spaced-apart teeth engageable with the underside of the flange, thus preventing removal of the closure. However, the closure can be removed by displacing its conically shaped skirt portion by inversion.
  • the invention has as its objects, among others, the provision of an improved safety closure which is of simple and economical construction wherein the closure is latched by cooperable latching means thereon and on the container, and wherein in the latched condition the latching means is completely covered and inaccessible and extremely difficult if not impoosible for a child to unlatch, but which can be readily unlatched by an adult for opening the container by removal of the closure.

  • one latching abutment and one latching tooth may be used, such arrangement is not desirable because of substantial free play when the container closure is closed in latched condition.
  • Container 2 is of more or less conventional construction, usually 6 having complementary threads by turning in one direction, usually in a clockwise direction, and removed from the neck by turning the same in a counterclockwise direction. The fully fastened position of the closure is determined when top 8 engages the rim 11 of the neck through the usual gasket 12 seated in the cap.
  • skirt portion 13 Integrally connected to the lower edge (all positions referred to hereinafter are with reference to the container standing in an upright position) of the sleeve portion 9 is a skirt portion 13, which is of continuously solid material all the way around such connection being along a circular hinge connection area 14 which is a molded section between the skirt and the cap as can be seen from FIG. 2.
  • skirt portion 13 can be displaced by inverting the same from a depending or downward closed position over the frustum conically shaped portion 4 of the container to an open upstanding position, as shown in FIG. 3.
  • Skirt portion 13 is also advantageously of frustum conical shape of substantially the same angle as the frustum conical portion 4 of the container, and in the closed position it engages such container portion 4 with the lower edge 15 of skirt portion 13 overhanging slightly cylindrical portion 3 of the container to provide a notch at 3.
  • This notch enables engagement of an implement, such as the fingernail, with the overhang to effect inversion of frustum conical section 13 from the position shown in FIG. 1 to the position shown in FIG. 3.
  • At least one latching abutment 21 is provided on the portion 4 of the container, and desirably two of them are provided at diametrically opposite sides of the container.
  • Such abutments 21 are advantageously formed as an integral part of the container, which is usually molded plastic or glass, wherein a recess 22 is formed during the molding thereof, leaving a flat upright abutment face 21.
  • At least one integral substantially flat latching tooth 23 is formed internally of the closure on skirt portion 13 which, in the down position of the skirt portion and after the closure is screwed on tightly, can engage abutment 21.
  • skirt portion 13 completely covers latching means 21, 23, thus rendering them inaccessible.
  • skirt portion 13 over cylindrical portion 3 of the container provides a notch around the periphery of the container which enables edge 15 of the closure to be engaged by a fingernail or other implement to invert displaceable skirt portion 13 to disengage the latching means for opening of the closure.
  • Substantial force is required to effect this inversion which a child of five or under, experimenting with the container, does not have; and even if such child should solve how the closure can be removed, which is unlikely, he would not be able to open the same, whereas an adult can readily invert the closure in the manner described.
  • two diametrically opposite latching teeth 23 are provided on skirt portion 13 in the embodiment of FIGS. 1 through 7, and two diametrically opposed latching abutments 21 on the container.
  • four equally spaced teeth 23 may be provided on the closure and four complementary abutments 21 on the container, as shown inFIGS. 8 and 9.
  • the closure is made entirely of integrally molded material, advantageously polypropylene or a copolymer of polypropylene and ethylene having built-in hinge properties.
  • Suitable plastic material for this purpose can be obtained from Eastman Kodak, known as Tenite polypropylene or Tenite polyallomer, having built-in hinge properties.
  • the polyallomer is used having the following properties determined by ASTM test methods indicated: flow rate 2.0 (by test method D1238L); density 0.896 (D1505); softening point C., 125 (D1525); Rockwell hardness R scale, 56 (D785).
  • any other suitable material can be employed having such hinge properties.
  • FIG. 2 discloses a closure for a conventional bottle neck having an outside diameter at the hinge connection area 14, indicated by dimension 24, of about 1.2 inches.
  • the height of the hinge connection area, indicated by dimension 26, is about 0.040 inch.
  • the wall thickness of the hinge connection, indicated by dimension 27, is about 0.012 inch, while that of skirt portion 13 is about 0.030 inch so as to have limited flexibility.
  • the wall thickness of the cap is greater, about 0.050 inch so as to be relatively stiff, and top 8 is about 0.050 inch.
  • the interior angle of conical skirt portion 13 is about 45.
  • the diameter at the loweredge 115 of skirt portion 13 is about 1.7 inches, and the width of the skirt about 0.32 inches.
  • hinge connection 14 be sufficently strong so that it can be repeatedly flexed to allow repeated inversion of the skirt portion from a down position to an upward position and vice versa, and yet be sufficiently stiff to require adult force to invert the conical section.
  • the thickness of section 13 and its angle should be such as to require adult force to invert the same.
  • a suitable dimensional range for the thickness of hinge area 14 is about 0.010 to 0.016 inch, with a height varying from about 0.040 to 0.050 inch.
  • the interior angle of the skirt may also vary, a suitable range being from about 30 to 60", but an angle of about 45 to the vertical has been found to be desirable for offering suitable resistance to inverting the conically shaped section but allowing the same to be inverted by adult force.
  • the greater the interior angle, measured from the vertical the easier it is to invert the skirt. In this connection, it is usually necessary to push the lower edge 15 upwardly at several spaced-apart locations before the skirt will assume a fully inverted position.
  • FIGS. 10 and 11 disclose the embodiment thus far described with the addition of a downwardly extending circular flange 31 embracing the container for the purpose of revealing to the initial purchaser whether the container has been opened beforehand or tampered with.
  • Flange 31 extends downwardly from the lower end of conical sec tion 13 and is connected thereto along a line of weak ness 32, allowing the flange to be torn from the closure.
  • a pull tab portion 33 can be torn away along an upright line of weakness 34 to separate the flange.
  • a head 36 on the container engages in a groove 37 in flange 31.
  • This engagement serves as a latch to prevent the skirt portion 13 from being displaced upwardly, to invert the same by pushing flange 31 upwardly and thus effecting unlatching of the closure. It is only when the flange portion 31 is torn away by pulling on a pull tab 33 to separate it along a line of weakness 34, and when tearing off the flange along line of weakness 32, that the skirt portion becomes accessible in the manner described for invert- .ing the same to open the container.
  • a thickness of about 0.005 to 0.007 inch at the lines of weakness, preferably in the lower range, will permit easy tearing away of flange 31.
  • the abutments on the container may be formed by providing spaced-apart slots 37 in the top portion of the container, as shown in FIG. 12, in which teeth 23 on skirt portion 13 of the closure can engage in the closed position of the closure, as shown in FIG. 13.
  • the respective transverse edges of the slots 37 which are engaged by the teeth when effort is made to unscrew the closure for opening it, thus serve as the latching abutments on the container.
  • FIG. 114 discloses a modified latching abutment formation on the container which is cooperable with the closure of FIG. 8 which has four equally spaced latching teeth about its periphery.
  • the principle is the same as previously described.
  • it is provided with a peripheral top ledge 41, and with four equally spaced integral projections 42 which have flat surfaces 43 that provide abutment faces for the teeth.
  • the upper edges 46 of faces 43 are at the same angle as the angle of frustum conical section 13 shown in FIG. 8, so that this section is in engagement with such edges in the latched position of the closure.
  • the upper surfaces 47 of the projections 42 are curved and taper substantially to a point at the edge of ledge 41 to provide camming surfaces for the closure teeth when the closure, with its conical section down, is turned to tighten it.
  • FIGS. 15 through 17 illustrate a safety closure arrangement adapted for such squeeze tubes.
  • the tube body ll is formed of the usual thin walled material, which in the case of tin may be in the order of 0.005 inch thick to enable ready squeezing.
  • the top of such tube, which is integral with the body, is made of heavier gauge, in the order of about 0.030 inch, so that it will maintain its shape and not readily deform.
  • top portion is made with a frustum conically shaped portion 52 ex tending downwardly from the usual threaded neck 53.
  • a cylindrical portion 54 having a plurality of upright radially extending spaced-apart teeth 56, is integrally molded with the frustum conically shaped portion 52; and a ledge 57 is formed below teeth 56.
  • Teeth 56 do not extend to the upper periphery of ledge 57, for a purpose to be described, and they serve as the latching abutments on the container.
  • the closure for the tube of FIG. comprises cap portion 58 integrally connected by hinge connection 59 to a frustum conically shaped section 60 having at its bottom a hinge connection 6E with a downwardly sloping flange 61a rigid with a circular depending flange 62 having spaced-apart internal latching teeth 63.
  • flange 62 provides a means for grasping by the fingers of a person to displace the conically shaped section 60 upwardly along hinge connection 59, and thus invert the same.
  • the closure teeth 63 engage the container abutments 56 as shown in FIG. 16
  • the closure cannot be removed by mere turning thereof, and the container recess above ledge 57 accommodates flange 62.
  • latching teeth 63 are not directly on the conically shaped section 60 of the closure it is only when such section is displaced or inverted that unlatching occurs, because the construction is such that the latching teeth on the closure, as in the previous modifications, are movable with movement or displacement of the conically shaped section.
  • the principle of the construction is the same as that previously described and can be used, if desired, on containers other than of the tube type.
  • FIGS. 18 and I9 illustrate another type of construction adapted for relatively large containers, such as 5- gallon size, where there may be a space limitation as to height.
  • the closure comprises cap portion 70, having top 7E, a screw-threaded connection with neck 72 of the container, and frustum conically shaped portion 73.
  • the conically shaped portion is hingedly connected along the top end of the cap at 74, and it is provided with latching teeth 76, each of which for conservation of space is formed of a diamond shaped indentation, as shown in FIG. 18, having an abutment surface 76a, as seen in FIG. 19a.
  • These abutment faces can engage abutments 77 on the container.
  • a bevel 79 is provided in the periphery of the container to accommodate skirt portion 73, which overlaps the outer faces of abutments 77 in the closed position. As described previously, a notch 81 is formed at the lower edge of skirt 73 to permit insertion of a fingernail or other implement for inverting the skirt to unlatch the closure to the position shown in FIG. 19.
  • the diamond shaped latching teeth have greater rigidity than the flat teeth of the previous embodiments, and if desired, may be employed in all embodiments hereof.
  • Some types of containers do not have a screwthreaded connection between the cap and the container, but are of the slip-on or slip-over type wherein the closure is pushed downwardly over the container neck.
  • the invertible conically shaped section 9t is hingedly connected along hinge connection 92 to a conically shaped downwardly extending flange 93 integral with the top 94 of the cap.
  • Neck 96 of the container has an outwardly extending pheriperal flange 97 which serves as a latching abutment; and in the closed position of the closure, inwardly extending teeth 98 below hinge connection 92 engage the underside of flange 97 to latch the closure.
  • a rim on the underside of top 94 provides a sealing and centering groove in which the container neck engages.
  • latching teeth 98 become disengaged from under flange 97 to permit removal of the closure, and latching can be obtained when the closure is placed on the container neck 96 and the conically shaped section 91 is inverted downwardly from the position shown in FIG. 21 to that in FIG. 20.
