A nutrition syringe cap. The nutrition syringe cap is formed by assembling a housing (1) and an inner core (2)； the inner core (2) comprises a needle cylinder stopper (7)； an annular wall (10) is integrally provided outside the needle cylinder stopper (7)； the wall surface of the annular wall (10) is provided with a cutting groove (11)； the thread-added profiling cutting groove (11) comprises oblique window opening and vertical window opening； threads are provided on the inner surface of the annular wall (10)； an annular groove (13) is formed in the annular wall (10)； outer meshing teeth (14) are provided on the annular groove (13)； the housing (1) is of a circular housing shape with openings at two ends, and the opening of one end is provided with a step-shaped clamping ring (8) matched with the annular groove (13)； the step-shaped clamping ring (8) is provided with inner meshing teeth (15) matched with the outer meshing teeth (14)； the outer surface of the housing (1) is of a table shape and/or frustum shape. Window opening outside the threads facilitates pressing down a syringe and ejecting double-thread teeth during mounting, so that the fatigue of medical workers is reduced； the principle that the gravity center is downward is utilized, and no matter the syringe cap is thrown on a table top at any angle, the inner core of the syringe is upward, so that nursing staff can conveniently insert the inner core into the syringe, and the fatigue of re-upward positioning of the syringe is reduced.La présente invention concerne un capuchon de seringue de nutrition. Le capuchon de seringue de nutrition est formé par assemblage d'un boîtier (1) et d'un noyau interne (2)； le noyau interne (2) comprend un bouchon de cylindre d'aiguille (7)； une paroi annulaire (10) est disposée d'un seul tenant à l'extérieur du bouchon de cylindre d'aiguille (7)； la surface de paroi de la paroi annulaire (10) est pourvue d'une rainure de coupe (11)； la rainure de coupe de profilage à filetag
