the present invention generally includes a removable handle 10 for use with a specimen container . as shown in fig1 and 2 , the specimen container generally includes a specimen container body 12 forming an inner wall 14 and an outer wall 16 . the inner wall 14 and the outer wall 16 further define a collection cavity 18 , a fluid collection and retrieval opening 20 , and a rim 22 . one embodiment of a removable and adjustable handle according to the present invention is shown in fig3 - 6 . a second embodiment is shown in fig7 - 9 . a third embodiment is shown in fig1 . a fourth embodiment is shown in fig1 . as shown in fig3 - 6 , and with particular reference to fig3 , the first embodiment of a removable and adjustable handle 10 according to the present invention generally includes a first body member 24 , a second body member 26 , and a locking member 28 connected to the second body member 26 by a flexible chord 30 . as shown in more detail in fig4 , the first body member 24 extends about a longitudinal axis l and forms an internal channel 32 , a channel member orifice 33 , guide holes 34 , and a first contact member 36 . the first contact member 36 forms a first contact surface 38 and an inner surface 40 . the second body member 26 , shown in detail in fig5 , forms locking holes 42 and a second contact member 44 . the second contact member 44 forms a second contact surface 46 and an outer surface 48 . the second contact member 44 is attached to the second body member by a channel member 50 . referring again to fig4 , the second body member 26 is slidably received by the internal channel 32 formed by the first body member 24 . the channel member 50 protrudes through the channel member orifice 33 , allowing the attached second contact member 44 to move when the second body member 26 is moved in a first direction a1 , or a second opposite direction a2 , as indicated by the arrows . when the second body member 26 is moved in the first direction a1 , the distance between the first and second contact members 36 , 44 is reduced . this allows the first and second contact members 36 , 44 , and more specifically , the first and second contact surfaces 38 , 46 engage the inner and outer walls 14 , 16 of the specimen container body 12 . conversely , when the second body member 26 is moved in the second direction a2 , the distance between the first and second contact members 36 , 44 is increased . this allows the handle 10 to be removed from the specimen container body 12 . referring again to fig3 , the locking member 28 , in combination with the guide holes 34 and the locking holes 42 , helps to keep the second body member 26 from moving after the first and second contact members 36 , 44 engage the inner and outer walls 14 , 16 of the specimen container body 12 . the locking member can be cylindrical , squared , rectangular , triangular , tapered , wedge - shaped , or any other suitable shape . however , because the locking member 28 is received by the guide holes 34 formed by the first body member 24 and the locking holes 42 formed by the second body member 26 ( when the guide holes 34 and the locking holes 42 are aligned ), the locking member 28 should form the same exterior shape as the guide holes 34 and the locking holes 42 . the first body member 24 , second body member 26 , and the locking member 28 are preferably formed from a material , such as plastic ( i . e ., polyethylene or high density polyethylene ), with plastic being preferred because it is inexpensive and disposable . however , reusable handles 10 ( including the chord 30 ) should be made from a material that can be autoclaved or otherwise sterilized , such as surgical grade stainless steel or other suitable material . in general , any sturdy material is clearly contemplated . referring again to fig4 and 5 , the first contact surface 38 and the second contact surface 46 are preferably arcuate in shape . an arcuate shape is preferred because a vast majority of the specimen containers currently being sold ( fig1 ) have a circular cross section when viewed through the fluid collection and retrieval opening 20 . however , the first contact surface 38 and the second contact surface 46 can resemble any shape , so long as the first and second contact surfaces 38 , 46 can engage the inner and outer walls 14 , 16 of the specimen container body 12 and securely hold the specimen container body 12 . fig7 - 9 show a second embodiment handle 10 ′ according to the present invention . the second embodiment handle 10 ′ is similar to the first embodiment handle 10 , with like reference numerals indicating like parts . however , as shown in detail in fig7 and 8 , the second body member 26 ′ forms external threads 52 which are received by internal threads 54 formed by the internal channel 32 ′ of the first body member 24 ′. a 360 ° swivel joint 53 is positioned adjacent to the second contact member 44 and the threaded portion 52 of the second body member 26 ′. as shown in fig9 , as the second body member 26 ′ is rotated in a first direction a3 , the second body member 26 ′ is threadedly advanced in the first body member 24 ′ and the distance between the first contact member 36 and second contact member 44 is decreased . conversely , if the second body member 26 ′ is rotated in a second direction a4 , the distance between the first contact member 36 and the second contact member 44 is decreased . this design eliminates the need for the locking members 28 , the guide holes 34 , and the locking holes 42 , as illustrated in fig3 . fig1 shows a third embodiment handle 10 ″ according to the present invention . as shown in this embodiment , the first and second contact surfaces 38 ′, 46 ′ can form notches 56 to accommodate threads 58 ( for a screw - on type lid ) formed adjacent the rim 22 ′ of the specimen container body 12 ′. similarly , as shown in fig1 , the first and second contact surfaces 38 ″, 46 ″ of a fourth embodiment handle 10 ′″ can form scored sections 60 to provide a raised surface area to help increase friction between the first contact surface 38 ″ and the interior wall 14 ″ of the specimen container body 12 ″ and between the second contact surface 46 ″ and the outer wall 16 ′ of the specimen container body 12 ″. in addition to being adjustable , an important aspect of this invention is that , shown generally in fig3 , the first contact member 36 and the second contact member 44 engage the inner wall 14 and the outer wall 16 of the specimen container body 12 securely but removably attaching the handle 10 to the specimen container ( preferably adjacent the rim 22 ). therefore , other types of handles or approaches , when used in connection with the specimen container , are clearly contemplated . an example is u . s . des . pat . no . 384 , 243 , herein incorporated by reference , which discloses a removable handle for cooking utensils . the invention has been described with reference to the preferred embodiment . obvious modifications and alterations will occur to others upon reading and understanding the preceding detailed description . it is intended that the invention be construed as including all such modifications and alterations .
