Abstract
A device 10 held and supported by one hand of a dentist's assistant to supply porcelain and other compounds 14 to a dentist, includes a cover member 16 that is held open by the same hand of the assistant that supports the device 10 to ultimately allow access by a dentist to the compounds 14 disposed upon a tray member 12. The cover member 16 is allowed to return to a closed position by the supporting hand of the assistant after the dentist has removed a selected compound 14 from the tray member 12, thereby preventing light from activating the compounds 14 while allowing the other hand of the assistant to perform other tasks required by the dentist.
Claims20
A dentist device for providing compounds to a dentist while an assistant supports the device with one hand such that the assistant can position a cover member of the device with the same hand to allow the dentist access to the compounds comprising:
- a tray member for receiving preselected compounds thereupon;
- a cover member for preventing light from engaging the compounds, said cover member being pivotally secured to said tray member;
- a support member secured to said tray member, said support member removably receiving a first portion of a first hand of a dentist's assistant supporting said tray member, said support member allowing the assistant to maintain said tray member in a substantially horizontal position, thereby maintaining the positions of the compounds disposed upon said tray member;
- and
- a lever member secured to said cover member such that a second portion of the first hand of the dentist's assistant is allowed to engage said lever member to ultimately urge said cover member to open and closed positions while said first portion of the assistant's first hand supports said tray member via said support member, whereby a second hand of the assistant is free to manipulate other instruments while said cover member is maintained open by the first portion of the assistant's first hand until portions of the compounds are removed from said tray member, whereupon, said cover member is re-disposed to a closed positioned by the first portion of the assistant's first hand immediately after the portions of the compounds are removed from said tray member, thereby minimizing the quantity of light engaging the preselected compounds portions remaining on said tray member.

A handheld dentist's tray comprising:
- a tray member for receiving preselected compounds thereupon;
- a cover member for preventing light from engaging the compounds, said cover member being pivotally secured to said tray member;
- a support member secured to said tray member, said support member removably receiving a first portion of a first hand of a dentist's assistant supporting said tray member, said support member allowing the assistant to maintain said tray member in a substantially horizontal position, thereby maintaining the positions of the compounds disposed upon said tray member;
- and
- a lever member secured to said cover member such that a second portion of the first hand of the dentist's assistant is allowed to engage said lever member to ultimately urge said cover member to open and closed positions while said first portion of the assistant's first hand supports said tray member via said support member, said lever member including a first portion secured to said cover member, and a second portion extending outside the periphery of a first end portion of said cover member, thereby allowing a thumb of a first hand of a dentist's assistant to engage and pivot said lever member to an open position that promotes the removal of portions of the preselected compounds disposed upon said tray member by a dentist, whereby a second hand of the assistant is free to manipulate other instruments while said cover member is maintained open by the first portion of the assistant's first hand until portions of the compounds are removed from said tray member, whereupon, said cover member is re-disposed to a closed positioned by the first portion of the assistant's first hand immediately after the portions of the compounds are removed from said tray member, thereby minimizing the quantity of light engaging the preselected compounds portions remaining on said tray member.

A tray device for dentists comprising:
- a tray member for receiving preselected compounds thereupon;
- a cover member for preventing light from engaging the compounds, said cover member including means for maintaining said cover member in an open position;
- a support member secured to said tray member, said support member removably receiving a first portion of a first hand of a dentist's assistant supporting said tray member, said support member allowing the assistant to maintain said tray member in a substantially horizontal position, thereby maintaining the positions of the compounds disposed upon said tray member;
- and
- a lever member secured to said cover member such that a second portion of the first hand of the dentist's assistant is allowed to engage said lever member to ultimately urge said cover member to open and closed positions while said first portion of the assistant's first hand supports said tray member via said support member, whereby a second hand of the assistant is free to manipulate other instruments while said cover member is maintained open by the first portion of the assistant's first hand until portions of the compounds are removed from said tray member, whereupon, said cover member is re-disposed to a closed positioned by the first portion of the assistant's first hand immediately after the portions of the compounds are removed from said tray member, thereby minimizing the quantity of light engaging the preselected compounds portions remaining on said tray member.
