  • the container although shown as relatively small and of a round configuration may be larger in size and of other configurations.
  • container is provided with side walls 2, a bottom wall 3 and an open top 4 and a rim 5 surrounding the open top. Near the open top 4 the side walls have an outwardly extending flange or tooth ring 6. Adjacent the open top 4 and between the open top and the tooth ring 6 is an outwardly extending rib 7.
  • the rib is provided with an angled upper surface 8, which extends outwardly and downwardly with respect to the rim 5, and a substantially planar lower surface 9 extending from the end of the upper surface 8 inwardly to the side walls.
  • the rib 7 has two slots 10 and 11 cut therein with the entire rib removed at the slots. Except for the slots, the rib is continuous around the container. Although two slots are shown, the rib may contain only one slot.
  • Carried by the tooth ring 6 is an indicating means 12 which may be in the form of an arrow or other marking, the purpose of which will be set forth later.
  • a cap or cover 15 Received on and covering the open end of the container l is a cap or cover 15, having an upper wall or top portion 16 and askirt or depending wall portion 17.
  • the skirt l7 flares outwardly and downwardly with respect to the upper wall and is provided with equispaced flutes 18.
  • the cap or cover 15 is made of a flexible plastic material and this, together with the flared skirt provides flexibility in the removal from and application to the container.
  • the skirt 17 also has a lower ring 19 having at one portion an outwardly extending tab 20. Extending upwardly in one of the flutes 18 is an indicating means 21 terminating in the approximate center of the tab in the form of a pointed bar.
  • the upper wall 16 of the cap has an inner surface 22 which is substantially planar throughout its extent. There may be a very narrow planar ring 23 adjacent the inner surface 24 of the-skirt 17, the ring sealingly engaging the rim 5 when the cap is in closed position on the container.
  • the inner surface 24 has thereon in one semi-circular portion two locking lugs 25 and 26 in circumferentially spaced relation to each other and extending radially inwardly therefrom a distance substantially equal to the thickness of the skirt. Said lugs are near respective opposite ends of the tab 20 where the ends of the tab merge into the skirt.
  • each locking lug has a planar upper surface 27 and a downwardly and outwardly extending angled lower surface 28.
  • Also carried on the inner surface of the skirt l7 and within the other semi-circular portion thereof are three camming lugs 29, 30 and 31, each of said camming lugs having a planar lower surface 32 and an angled upper surface 33 similar to the shape of the locking lugs 25 and 26.
  • the remainder of the inner surface of the skirt between the camming lugs and the locking lugs and between the locking lugs being substantially a plane surface.
  • the camming lugs 29, 30 and 31 engage the lower surface of the rib 7 when the cap or cover is in locked or closed position on the container and aid in sealing complished by rotating the cap or cover relative to the container until the indicating means 21 on the cap or cover is aligned with the indicating means 12 on the container at which time the locking lugs 25 and 26 are aligned with the slots and 11.
  • the locking lugs will pass through the slots when the tab is raised upwardly and with the pivotal and fulcrum action of the camming lugs 29, 30 and 31 the cap or cover will be easily removed.
  • the cap or cover may be applied to the container in any position by first placing one of the semi-circular portions of the cap or cover under the rib on the container and then forcing the other semicircular portion o'ver the rib whereupon the lugs in the other semi-circular portion will pass over the rib with a snap action.
  • the flared skirt of the cap or cover extends outwardly to a point wherein it substantially covers the tooth ring with only the tab extending beyond the tooth ring.
  • the rim 19 of the skirt is also in contact with the upper surface of the tooth ring so that the cap or cover cannot be forced from its closing position by engagement or prying under the rim with the teeth or any instrument or tool except when the locking lugs are aligned with the slots in the rib.
  • the cap or cover may be difficult to turn with respect to the container to align the locking lugs with the slots in the rib.
  • another tab 35 is provided which is diametrically opposite to the tab 20.
  • lateral pressure against each tab will easily aid in turning the cap or cover.
  • the extra tab will not aid in the removal of the cap or cover from the container.
  • the indicating means 21 will only be on the tab 20.
  • FIG. 6 Another aid in the turning of the cap or cover is shown in FIG. 6 wherein a bar 36 is provided on the top of the cap or cover.
  • the bar 36 may be molded to or affixed diametrically across the cap or cover and grasped between the thumb and forefinger for turning movement.
  • the cap or cover may be modified as shown in FIG. 8 wherein a thick inner plug 37 is provided on the inside of the cap or cover.
  • the plug is of a size sufficient to pass within the wall of the container and be in engagement therewith.
  • a recess 38 is between the plug 37 and the skirt 17 to allow the insertion of the upper end of the container and the rib 7.
  • the locking lugs 25 and 26 and the camming lugs 29, 30, 31 are also on the inner side of the skirt. The plug aids in sealing the container to prevent contamination of the contents and to provide a good seal.
  • FIG. 9 A further modification of the cap or cover and the container is shown in FIG. 9, wherein the container is provided with a thread member 40 adjacent the top 41 cap or cover will draw the cap or cover downwardly upon the container to effect a tighter seal.
  • the cap or cover In an opening operation the cap or cover must be turned to first release the thread engagement and then place the lock ing lugs with the slots before removal of the cap or cover as described heretofore.
  • the cap or cover as shown in FIG. 9 may have the plug 37 therein or may be plain as shown in FIG. 4.
  • the container may be further modified as shown in FIG. 10, wherein the upper end of the container 44 is extended with the upper end or rim 45 having an outstanding bead 46 therearound.
