Abstract
The present invention provides a needle for injecting substances into food products, and a method of making such needles, such devices comprising a generally tubular body having a pointed end and a second end, an axial duct in the tubular body, openings located on the tubular body near the first and second ends, and an insert located in the axial duct between the second end of the tubular body and the opening located near the second end of the tubular body, whereby material is prevented from being deposited in the axial duct between the second end of the tubular body and the opening located near the second end of the tubular body.
Claims20
A needle for injecting substances into food products, the needle comprising:
- (a) a generally tubular body having:
- (i) a first end having a pointed tip;
- (ii) a second end;
- (iii) an axial duct in said tubular body, said axial duct extending out of the second end of the tubular body and having a first central axis;
- (iv) at least one first opening located near said first end of said tubular body, said at least one first opening having a second central axis generally perpendicular to said axial duct;
- and
- (v) at least one second opening located near said second end of said tubular body, said at least one second opening having a third central axis, generally perpendicular to said axial duct;
- and
- (b) an insert located in said axial duct generally at said second end of said tubular body between said at least one second opening, and said second end of said tubular body, whereby material is prevented from being deposited in said axial duct between said at least one second opening and said second end of said tubular body.
A needle having a generally tubular body for injecting substances into food products, the needle comprising:
- a first end and second end, wherein said first end has a pointed tip and said second end is closed;
- an axial duct having a first central axis and extending from said first end of said tubular body to a planar surface of an insert within the axial duct, said planar surface being generally perpendicular to said first central axis;
- a first opening on said tubular body, located near said first end of said tubular body;
- and
- a second opening on said tubular body, located where said axial duct meets said closed second end of said tubular body, said second opening having a second central axis disposed generally parallel to said planar surface plane, whereby material is prevented from being deposited in said axial duct between said second opening and said second end of said tubular body.
A needle for injecting substances into food products, the needle comprising:
- a generally tubular body, made of a stainless steel, the tubular body having:
- a first and second end;
- an axial duct in said tubular body, said axial duct having a first central axis and extending out of the second end of the tubular body;
- a pointed tip at said first end of said tubular body;
- at least one first opening located near said first end of said tubular body, said at least one first opening having a second central axis, said second central axis generally perpendicular to said axial duct;
- and
- at least one second opening on said tubular body located near said second end of said tubular body, said at least one second opening having a third central axis, generally perpendicular to said axial duct;
- an insert, made of a stainless steel, having a first insert end and a second insert end, the insert located in said axial duct generally at said second end of said tubular body with the first insert end near the said at least one second opening, and the second insert end near the said second end of said tubular body, said first insert end defining a planar surface being generally perpendicular to said axial duct;
- and
- a cap, located on the second insert end, whereby material is prevented from being deposited in said axial duct between said at least one second opening and said second end of said tubular body.
