Description

FIELD OF THE INVENTION

The present invention relates to holders for holding jars while loosening tight caps therefrom.

BACKGROUND OF THE INVENTION

Opening a jar with a tight cap is often tedious, especially for persons with limited manual strength, such as persons with arthritis, carpal tunnel syndrome and the like. Therefore, various attempts have been made to provide a retaining holder for a jar during the opening thereof, such as the pad-type jar gripper as described in U.S. Pat. No. 3,999,361 of Bingaman. However, the resilient compressible angular array of upwardly extending fingers of Bingaman '361 cannot be adjusted for jars of varying diameters.

Other jar holders include wedge shaped retaining walls, wherein the cap of the jar is inserted in a wide open portion until the diameter of the cap is gripped by the retaining members, at a point where the opening between the corresponding parts of the retaining walls, such as described in U.S. Pat. No. Des. 258,192 of Maloney, U.S. Pat. No. Des. 296,293 of Wheeler, U.S. Pat. No. Des. 333,958 of Wheeler, and U.S. Pat. No. Des. 257,318 of Zorzi.

Similarly, U.S. Pat. No. 5,097,729 of Brown includes a wedge shaped pair of gripping handles having a gripping band tightenable around a cap to be removed. However, these openers grip the cap only, and do not hold the jar to which the cap is attached, which further reveals the need for a jar gripper, as opposed to a cap gripper. The user still has to grip the jar of a generally wider diameter, which is a problem for persons with limited gripping powers.

Other screw cap removers are described in U.S. Pat. No. 4,306,470 of Woloszyn, which includes a lockable cam urging jaw members about a jar cap to be loosened, U.S. Pat. No. 4,165,115 of Olsson, U.S. Pat. No. Des. 265,647 also of Olssen, U.S. Pat. No. 3,950,801 of Morrison, U.S. Pat. No. Des. 351,970 of Barrio, U.S. Pat. No. 5,617,765 of Bennett, which includes worm gears moving gripping surfaces against a lid, U.S. Pat. No. 5,365,806 of Panemest, U.S. Pat. No. 5,647,251 of Hardman, U.S. Pat. No. Des. 303,343 of Nuss, U.S. Pat. No. 4,766,781 of Grise, which includes a lid engaging funnel with a gripping insert therein, U.S. Pat. No. Des. 249,323 of Hutson and U.S. Pat. No. Des. 249,324 also of Hutson. Moreover, U.S. Pat. No. 4,107,741 of Mikituk describes a locking system for tightening a blending jar of a blender in place for performing a blending operation.

OBJECTS OF THE INVENTION

It is therefore an object of this invention to provide a jar holder which firmly holds a jar, rather than a cap of a jar, for loosening the cap from the jar.

It is another object of this invention to provide a jar holder which frees the hands of a user during the jar opening task.

It is a further object of this invention to provide an adjustably sized jar holder that can hold jars of various sizes while dislodging the cap from the jar.

It is also an object of the present invention to improve over the disadvantages of the prior art.

SUMMARY OF THE INVENTION

In keeping with these objects and others which may become apparent, the present invention includes a flexible mounted jar holder which operates by resiliently and tightly holding a jar upon a flat base while loosening a cap therefrom.

The jar holder includes a resilient, ribbed gripping first retaining strap which locks the jar in place. A locking member includes at least one fixed post, such as a pair of upwardly extending fixed posts, and a third rotatable cam post, which includes an ellipsoid cross sectional diameter.

When the retaining strap is wrapped around an outside circumference of the jar, it is then inserted between one of the upwardly extending fixed posts and the rotatable locking cam post. Pulling the distal leading edge of the retaining strap therebetween causes the cam post to be rotated into place, and locks the retaining strap between the fixed post and the cam post.

A preferred embodiment includes a further retaining means which includes at least one further flexible strap, such as a strip, which is urged against a portion of the outer circumference of the jar to be held, at a point opposite to where the first retaining strap is urged against the outer circumference of the jar to be held. This at least one further flexible retaining strap, such as a strip, is stretched linearly between the pair of fixed posts. Preferably the at least one further flexible retaining strap includes a pair of further retaining straps, such as strips, each having respective looped ends insertable over each respective fixed post. The pair of further retaining straps therefore includes a further lower retaining strap below the jar engaging position of the first retaining strap. The further upper retaining strap extends thereabove.

The first retaining strap also includes a looped proximal end portion engagable over one post of the pair of fixed posts.

As noted above, at a distal end of the first retaining strap there is provided the locking end portion, which is lockable between one of the fixed posts and the movable cam post.

At a mid portion of the first retaining strap is preferably provided a wider jar engaging portion, which includes preferably a pair of parallel strips separated by a gap, to adapt to changing diameters of upper and lower portions of the jar to be opened, or to be able to grip both short or tall jars. This main retaining strap is wrapped around the jar and locked in place by the turning of the cam post until tightened by the movement of the retaining strap between the fixed post and the rotatable cam post.

DETAILED DESCRIPTION OF THE INVENTION

The following description of the drawings is merely illustrative of one embodiment, and is not meant to be limiting the scope of the invention.

FIGS. 1-3A show jar holder 1 for holding jar 2 having exterior circumferential girth 3 and tightened screwable cap 4 thereupon. Jar 2 is fixed in place by first retaining strap 20. Jar holder 1 includes flat base 10 upon which jar 2 sits while being held in place for manually opening cap 4 therefrom.

Base 10 preferably includes downwardly extending shoulder 11 providing a right angle corner 12 therebetween, for holding base 10 firmly against the edge of a surface 5 of a tabletop or countertop. Friction inducing pads 13, such as of foam rubber or other natural or synthetic compressible material, may be placed underneath base 10, between base 10 and the tabletop or countertop. To retain base 10 firmly in place without movement, fastener 14, such as a suction cup releasable by pivotable lever 15, is provided between base 10 and surface 5. Base 10 also includes at least one fixed post 16, preferably a pair of fixed posts 16, 17, extending upwardly from base 10.

To engage a portion of circumferential girth 3 of jar 2, at least one flexible but taunt strip 18, such as a pair of taunt strips 18, 19, extends between fixed posts 16, 17. When a pair of strips 18, 19 is used, one strip 18 extends below a proximal portion 20a of retaining strap 20. Each strip 18, 19 includes respective pairs of post-engaging loops 18a, 18b or 19a, 19b. Loops 18a, 18b are slid over respective posts 16, 17, and looped proximal end 20a of retaining strap 20 is slid over a fixed post, such as fixed post 16, above looped end 18b of strip 18. Afterwards, distal lockable end 20b is wrapped around the circumferential girth 3 of jar 2 and then slid between fixed post 16 and rotatable cam post 30, which includes ellipsoid portion 30a, having a wider diameter in one direction, cam post 30 is alternatively pivotable against distal end 20b of retaining strap 20, squeezing and locking distal locking end 20b of retaining strap 20 between cam post 30 and fixed post 16. When pivoted in an opposite direction, the wider part of cam post 30 is released from against distal locking end 20b of retaining strap 20.

Retaining strap 20 further includes a mid jar engaging portion 20c, which extends between proximal looped end 20a and distal locking end 20b. Preferably, as shown in FIG. 9, mid jar engaging portion 20c includes upper portion 20d and lower portion 20e, both separated by recess gap 20f. In that manner if jar 2 is bottled necked, with an upper neck having a smaller diameter than a wider lower portion, the differences in circumference between the upper and lower portions of the jar can be compensated for when bottle engaging portions 20e, 20d are urged against jar 2. Having two bottle engaging portions 20d and 20e also allows both short and tall jars to be held in place, since lower portion 20e can accommodate single short jars, but both upper and lower portions 20d, 20e together can hold a tall jar in place.

Therefore, in a preferred embodiment shown in FIGS. 1-9, jar 2 is squeezed between strips 18, 19 on one side and retaining strap 20 on the other side, as shown from above in the top plan view of FIG. 2.

The vertical arrow provided in FIG. 3, shows the slidable direction of looped ends 18a, 19a of strips 18, 19 upon fixed post 16. As shown in FIG. 6A, preferably strips 18, 19 include jar engaging members 20g, such as flexible protrusions.

FIGS. 5 and 7 show cam post 30 having wider portion 30a, which when cam post 30 is pivoted, squeezes distal end 20b of first retaining strap 20 between fixed post 16 and cam post 30.

When held in place, jar 2 is securely locked in place and is ready for removal of cap 4 therefrom by manual twisting of cap 4 in the approximate loosening direction.

Moreover, FIG. 3B shows an alternate embodiment wherein post engaging loop 20a of retaining strap 20 is placed over post 17, instead of post 16, above loop 18a of strip 18, instead of above loop 18b on post 16. Retaining strip 20 then extends around side and front portions of jar 3, and is inserted and locked in place between post 16 and cam post 30 extending up from base 10 with shoulder 11.

FIG. 3B does not show upper strip 19, which is normally placed above retaining strap 20. As noted before, upper strip 19 is held in place by the placement of respective looped ends 19a and 19b over respective posts 17 and 16, as shown in FIGS. 1, 3A and 9.

It is further noted that other modifications may be made to the present invention without departing from the scope of the invention, as noted in the appended claims.
