DETAILED DISCLOSURE OF EMBODIMENTS

Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with technology- or business-related constraints, which may vary from one implementation to another. Moreover, it will be appreciated that the effort of such a development might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

In order to present the background for the inventive concept more vividly, reference is now made to FIG. 1, showing a reusable handle for cups of WO2013163725, described in more details in paragraphs of [027] to [0058] and FIGS. 1 to 4 of WO2013163725 The reusable handle for cups shown in FIG. 1, according to WO2013163725, includes a quick-mount mechanism mounted to the handle portion and being adapted for removable attachment to the disposable cup. Notably the reusable handle for cups shown in FIG. 1 is adapted for removable attachment to the disposable cup including a cover, as shown in FIGS. 1 and 3-4 of WO2013163725.

It should be appreciated that in order to attain a sufficient compressing force, so as to removably attach the reusable handle for cups shown in FIG. 1 to and lift a disposable cup with a cover, as shown in FIGS. 1 and 3-4 of WO2013163725, the reusable handle for cups shown in FIG. 1 includes quick-mount mechanism mounted to the handle portion. The quick-mount mechanism requires an additional step of actively locking the quick-mount mechanism, see for instance paragraphs [0034] and [0036] of WO2013163725, order to attain a sufficient compressing force, so as to removably attach the reusable handle for cups shown in FIG. 1 to and lift a disposable cup with a cover.

Reference is now made to FIGS. 2A and 2B, showing a detachable cup handle of U.S. Pat. No. 6,588,064, described in more details in column 5 lines 1 to 42 as well as FIGS. 6 and 7 of U.S. Pat. No. 6,588,064. Notably the detachable cup handle of U.S. Pat. No. 6,588,064, shown in FIGS. 2A and 2B, is suboptimal for attaining a sufficient compressing force, so as to attach the detachable cup handle to and lift a disposable cup with a cover.

Reference is now made to FIGS. 3A and 3B, showing a detachable cup handle of U.S. Pat. No. 5,788,298, described in more details in column 2 lines 1 to 55 as well as FIGS. 4 and 5 of U.S. Pat. No. 5,788,298, which are incorporated herein by reference. Notably the detachable cup handle of U.S. Pat. No. 5,788,298, shown in FIGS. 2A and 2B, is suboptimal for attaining a sufficient compressing force, so as to attach the detachable cup handle to and lift a disposable cup with a cover.

In accordance with some preferred embodiments of the present invention reference is now made to FIGS. 4A and 8B, respectively showing improved cup handle 200 and locking mechanism 210. Cup handle 200 comprises locking mechanism 210 disposed oppositely to back portion 212. Back portion 212 forms a continuum with top portion 214 and bottom portion 218. Top portion 214 comprises frontal extension 216. Top portion 214 optionally comprises lateral appendages 226.

Bottom portion 218 preferably embodies an inwardly arcuate shape. Bottom portion 218 extends towards and forms a continuum with front portion 222. Bottom portion 218 extends towards and forms a continuum with front bottom portion 224. Front bottom portion 224 optionally comprises lateral appendages 228.

Front portion 222 forms a continuum with blade 220. Blade 220 typically embodies an inwardly arcuate shape, so as to exert a greater force on the pointed front edge thereof. Blade 220 comprises an arcuate front face and back face. Blade 220 optimally comprises planar back face 230, slanted towards the bottom. As can be particularly seen in FIG. 8A, back planar face 230 of blade 220 defines an acute angle between the front arcute face of blade 220. It is noted that prior art handles according to WO2013163725, U.S. Pat. No. 6,588,064 and U.S. Pat. No. 5,788,298 comprise a blade where a back planar face does not define an acute angle to the front arcute face of the blade. Thus WO2013163725, U.S. Pat. No. 6,588,064 and U.S. Pat. No. 5,788,298 describe blades where a front planar face defines an acute angle to the back arcute face of the blade. The inventor has extensively experimented with various configurations of the blade and has established that the configuration of blade 220 where back planar face 230 defines an acute angle to the front arcute face of blade 220 is particularly beneficial for exerting a greater compressing force by blade 220 of locking mechanism 210 onto circular rim 252, allowing lifting cup 250, with a cover (not shown), of lager weights with handle 220.

Moreover, as can be appreciated from FIG. 8A, planar face 230 of blade 220 defines a reflex angle ranging between 300 and 340 degrees relatively to abscissa X. It is noted that prior art handles according to U.S. Pat. No. 6,588,064 and U.S. Pat. No. 5,788,298 do not comprise a blade where a planar face defines an acute angle between the front arcute face of the blade. Thus U.S. Pat. No. 6,588,064 and U.S. Pat. No. 5,788,298 describe blades where a planar face defines a reflex angle of about 270 degrees relatively to abscissa X, essentially paralleling to ordinate Y. The inventor has extensively experimented with various configurations of the blade and has established that the configuration of blade 220 where planar face 230 defines a reflex angle ranging between 300 and 340 degrees relatively to the abscissa X is particularly beneficial for exerting a greater compressing force by blade 220 of locking mechanism 210 onto circular rim 252, allowing lifting cup 250, with a cover (not shown), of lager weights with handle 220.

Alternatively or additionally blade 220 comprises lateral extensions 232. As can be particularly seen in FIG. 4A to 6, lateral extensions 232 define a widened pointed terminal portion of blade 220, wherein the width of the front edge of the pointed terminal portion of blade 220 is larger than the base portion of blade 220. It is noted that prior art handles according to WO2013163725, U.S. Pat. No. 6,588,064 and U.S. Pat. No. 5,788,298 do not comprise lateral extensions that define a widened pointed terminal portion of the blade, wherein the width of the front edge of blade pointed front portion of the blade. Thus WO2013163725, U.S. Pat. No. 6,588,064 and U.S. Pat. No. 5,788,298 describe blades where the front portion of the blade is of a uniform width relatively to the rest of the blade, so that the width of the terminal portion of the blade is essentially of the same width as the base of the blade. The inventor has extensively experimented with various configurations of the blade and has established that the configuration of blade 220 with lateral extensions 232 which define a widened pointed terminal portion of blade 220, wherein the width of the front edge of the pointed terminal portion of blade 220 is larger than the base portion of blade 220, is particularly beneficial for exerting a greater compressing force by blade 220 of locking mechanism 210 onto circular rim 252 allowing lifting cup 250, with a cover (not shown), of lager weights with handle 220.

Frontal extension 216 of top portion 214 preferably comprises a slanted back planar face, which terminates with upwardly pointed backward edge 234. Slanted back planar face of frontal extension 216 preferably defines a reflex angle of about 250 degrees relatively to abscissa X. It is noted that prior art according to WO2013163725, U.S. Pat. No. 6,588,064 and U.S. Pat. No. 5,788,298 do not teach handles comprising a slanted back planar face which terminates with an upwardly pointed backward edge. Thus WO2013163725, U.S. Pat. No. 6,588,064 and U.S. Pat. No. 5,788,298 describe frontal extensions comprise an arcuate back face without nay upwardly pointed backward edge. The inventor has extensively experimented with various configurations of the blade and has established that the configuration of blade 220, with a slanted back planar face, which terminates with upwardly pointed backward edge 234, is particularly beneficial for attachment of cup handle 200 to cups without covers, as can be seen in FIGS. 8A and 8B.

Referring to FIGS. 5 and 7 shows cogs 240, disposed on front portion 222 and bottom front portion 224. Cogs 240 terminate with a pointed tip, configured to affix handle 200 to the surface of cup 250. Upon lifting cup 250 a force is exerted by front portion 222 and bottom front portion 224 in the direction of the exterior surface of cup 250. Consequently the pointed tips of cogs 240 affix handle 200 and prevent any sliding thereof over the surface of cup 250. Cogs 240 are an effective substitution to the flanking wings, such as flanking wings on the cup handle disclosed in U.S. Pat. No. 6,588,064. The lengths of cogs 240 is not sufficient to penetrate throughout cup 250 but rather to merely scratch and/or form minute indentations in the exterior surface of cup 250.

Handle 200 typically further comprises inner bumper extension 236, disposed on the bottom face of top portion 214. Inner bumper extension 236 is configured to prevent the sliding of rim 252 of cup 250 backwards.

According to another embodiment of the present invention reference is now made to FIG. 9 showing improved cup handle 260. Handle 260 comprises locking mechanism 210 as well as essentially the same constituents as handle 200, shown in FIG. 4A to 8B, but has a modified front bottom portion 262. Front bottom portion 262 embodies a circular or discoid shape, preferably resembling a coin. Front bottom portion 262 is optionally introducible into a coin operated lock of supermarket carts.

According to another embodiment of the present invention reference is now made to FIG. 10 showing improved cup handle 270. Handle 270 comprises locking mechanism 210 as well as essentially the same constituents as handle 200, shown in FIG. 4A to 8B, but has a modified front bottom portion 272. Front bottom portion 272 embodies a smaller shape, optimized for smaller cups as well as requiring less material.

It is noted that according to the present invention improved cup handles 210, 260 and 270, shown in FIG. 4A to 8B, comprising optimized locking mechanism 210, sustain attaching handles 210, 260 and 270 to cups with cover as well as without cover. Moreover it will be appreciated that improved locking mechanism 210, optimized to sustain a greater compressing force, thereby allowing handles 210, 260 and 270 to lift larger cups 250, particularly cups compliant with size standards of 3 oz, 4 oz, 6 oz, 7 oz, 8 oz, 9 oz, 10 oz, 12 oz, 16 oz, 20 oz, 22 oz, 32 oz and 64 oz, inter alia with standard covers.

It is noted that according to the present invention improved cup handles 210, 260 and 270, shown in FIG. 4A to 8B, comprising optimized locking mechanism 210, sustain attaching handles 210, 260 and 270 the physical parameters of which are set forth in TABLE 1, inter alia with standard covers.

TABLE 1 Cup Dimensions mm Cup Capacity Cup Size Top Bottom Height 120 ml  4 oz 63 44 64 190 ml  6 oz 72 53 76 220 ml  7 oz 74 52 83 280 ml  8 oz 80 52 92 300 ml 10 oz 90 60 95 400 ml 12 oz 90 60 110 510 ml 16 oz 90 61 135 600 ml 20 oz 90 62 150 660 ml 22 oz 90 61.5 168 720 ml 24 oz 90 63 177 960 ml 32 oz 104 71 180 550 ml 16 oz-E 95 61.5 120 700 ml 22 oz-E 95 61.5 148

As can be seen in FIG. 8A, handle 200 is initially appended cup 250 so that locking mechanism 210 is disposed above rim 252. Then, in order to lock locking mechanism 210, as seen in FIG. 8B, the user slightly pulls bottom portion 218 in a downward direction, namely in the negative direction of ordinate Y, so that blade 220 spontaneously snaps into place.

Thereafter the user can lift and tilt cup 250 by holding handle 200. As opposed to WO2013163725, handle 200 obviates the need in an addition step of actively locking the locking mechanism, which is required WO2013163725, since handle 200 is spontaneously activated and blade 220 automatically snaps into place, merely by slightly pulling bottom portion 218 in a downward direction, namely in the negative direction of ordinate Y.

It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described herein above. Rather the scope of the invention is defined by the claims which follow:
