for a container may be seen, the closure including a top por-tion 10 with a depending annular flange 11 joined by a thin frangible wall 12 to the upper edge of a depending distortable annular tear skirt 13. The lower edge O:e the annular tear skirt is integrally joined by a second thin f'rangible wall 14 -to the upper edge of an annular ring 15 which in turn is integrally formed with a flexible handle 16 of a generally U-shape, the ends of the arms of the generally U-shaped handle 16 extending from locations on -the opposite sides o e the ring 15. The handle 16 is initially -formed as illustrated in solid lines in Figure l of the drawings and like the remainder of the tamper evident closure is f'lexible and capable of being moved to an upright position as shown in broken lines in Figure l~ The base of the generally U-shape of' the handle 16 is a straight portion extending between the arms of the handle 16 and oppositely disposed ribs 17 are ~ormed thereon to reinf'orce the same and provide a more convenient and comfortable hand grip.
The tamper evident closure with the handle is -formed of' a resilient molded plastic material. The several portions o~' the . . ~

closure being moldecl of different thicknesses o.E material, for example the top 10 O:e the cap portion is of a firs-t known thickness so as to be able to carry an annular downturned sealing flange 18, see Figures 3 and 4, on its inner surface.
The depending flange 11 on the peripheral of the top 10 has a relatively thicker wall section than the known thi.ckness of the top 10 and is preferrably provided with a continuous thread pattern 19 on its inner surface, see Figures 3 and 4. The continuous thread pattern may be formed in an i.nterrupted configuration and the configuration of the thread pattern used to frictionally engage a neck portion of a container or it may threadably engage the same as illustrated in the embodiment of the invention shown in Figures 3 and 4 of the drawings. The lower edge of the depending flange 11 is integrally formed with the thin deformable resilient flexible tear skirt 13 and the thin wall section of the tear skirt 13 extends from the thin frangible wall 12 where it joins the lower edge of the annular flange 11 to the second thin frangible wall 14 by which it is affixed to the upper edge of the ring 15. The ring 15 is formed with a somewhat thicker annular body and reinforced by a plurality of ~L 3 ~
circumferentially spaced ribs 20 positioned vertically on the exterior o~ the ring 15. The ribs 20 and the handle 16 are arranged to permit the ring 15 to be stretched and positioned downwardly over an annular rib 21 ~ormed on a container C just below the neck portion thereof which receives the cap portion oi the closure. The resilient quality of the material irom which the closure is made and the di~ering thicknesses o~ the several wall sections enable the ring 15 to be sel~-retaining on the container beneath the annular rib 21 so that when the container such as a two li-ter size is ~illed with a beverage the same can be picked up and carried by the handle with no possibility o~ the ring and handle-moving away from their position beneath the annular rib 21 on the neck of the container. Sti]l reierring to Figure 3 of the drawings it will be seen that when the ring 15 is moved downwardle forceably over the annular rib 21 on the container C the ilexible and resilient tear skirt 13 is stretched to con~orm with -the shape of the annular rib 21 to which it closely adheres and the thin ~rangible wall 12 and the secondary thin i'rangible wall 14 are spaced vertically and horizontally with respect to one another. By re~erring now ~ 3 ~
to Figures 1 and 2 o~ the drawings, i-t will be seen that the depending flexible tear skirt 13 has a pull tab 22 formed integrally therewith which extends beyond a vertically positioned frangible wall 23 defining the ends of the flexible tear skirt 13 and that when the pull tab 22 is grasped and moved to the right as shown in Figure 2 o~ the drawings, the thin ~rangible walls 12,14 &23 will separate.withthe one end of the Ilexible tear skirt 13 moving away from its engagement with the annular flange 11 and the ring 15 so as to be completely removed from the tamper evident closure with handle leaving the closure portion of the device on the container C as shown in Figure 4 of the drawings and the ring 15 with the handle 16 still positioned on the neck of the container C and beneath the annular rib 21 thereon.
It will occur to those skilled in the art that the distorted position of the flexible tear skirt 13 o~ the device performs two ~unctions. The first of these occuring when it is removed providing visible evidence of the fact that the closure has been tampered with and/or opened and second assisting in securing the cap portion of the device including the top 10 and the annular depending flange 11 in position on the neck o~ the container C
, i , .
!, around the opening thereo~ and in sealing relation thereto.
There is a supplemental or a third advantage which is best illustra-ted in Figure 3 of the drawings wherein it will be observed that when the flexible -tear skirt 13 is in stretched installed position it assists in holding and positioning the ring 15 on the neck of the container C beneath the annular rib 15 on the container. This fact contributes to the security oi the placement of the ring 15 to which the hand].e 16 is attached insuring tha-t it will not accidentally move upwardly and over the annular rib 21 of the container when the container and its liquid contents are lifted by the handle.
It will thus be seen that the tamper evident flexible closure with handle for a container disclosed herein has an effective sealing means with respect to the opening in the container over and around which it is positioned as well as the tamper evident tear skirt which changes the appearance of the closure substantially when it is removed and it provides a highly desirable convenient and practical handle for carrying the container and the beverage or other liquid contained therein.
An additional advantage inherent in the construction disclosed is the ability of the closure portion o~ the device to be reapplied to the container about the opening therein to provide resealing or closing of the same as desired. Having thus described my invention, what I claim is:
