- the gasket stopper 68 is attached. Thereby, the prefilled syringe 10 shown in FIG. 1 is completed.
- the cross-sectional shape of the base end side inner peripheral surface 50a of the cover part 50 is formed when the cover part 50 heat-deforms with the heat
- the base-end-side inner peripheral surface 50a of the cover portion 50 after the sterilization process has an elliptical shape that matches the two protruding portions 30 provided in the lock adapter 100, as shown in FIG. That is, regardless of the circumferential position of the protrusion 30 and the cover 50, the protrusion 30 pushes a part of the cover 50 outward, so that the other part of the proximal end inner peripheral surface 50a is surely formed. Is deformed inward to form the small distance portion 50b. Thereby, the function of preventing the cap 14 from loosening with respect to the female luer 23 is exhibited.
- the cap 14 is attached to the female luer 23 of the outer cylinder main body 12.
- the sealing portion 39 made of an elastic material is in close contact with the distal end surface of the female luer 23, so the opening 23 b of the female luer 23 is liquid-tightly sealed.

- the cap 14 In a state where the cap 14 is attached to the female luer 23, that is, in a state where the pressing portion 28 is crushing the sealing portion 39, the cap 14 is rotated in the direction in which the cap 14 is loosened based on the elastic force of the sealing portion 39. The force to try acts. If the cap 14 is loosened before the prefilled syringe 10 is used, the medicine M may leak out. Therefore, in the present embodiment, the protrusion 14 is provided on the outer peripheral surface of the proximal end of the female luer 23 to prevent the cap 14 from being loosened before use.
- the protrusion provided on the outer peripheral surface on the proximal end side of the female luer 23 is formed in the small distance portion 50b of the main body portion 34 (cover portion 50) that has become a non-circular shape (elliptical shape) due to thermal deformation during sterilization.
- the part 30 is engaged with high precision. For this reason, loosening of the cap 14 before use is effectively prevented. Specifically, when the cap 14 is rotated in a direction in which the screw 14 and the female luer 23 are loosened due to the small distance portion 50b, the resistance for the small distance portion 50b to get over the protruding portion 30 is reduced. appear. As a result, the cap 14 is difficult to loosen.
- the small distance part 50b functions as a loosening resistance generating part.
- the cap 14 When using the prefilled syringe 10, the cap 14 is opened as shown in FIG. 8A. Specifically, with the posture in which the female luer 23 is directed upward, the cap 14 is rotated in a predetermined direction with respect to the outer cylinder main body 12, thereby engaging (screwing) the cap side fixing portion 44 and the female side fixing portion 26. And the cap 14 is removed from the female luer 23. In this case, when a rotational operation force of a predetermined level or more is applied to the cap 14, the base end side of the main body portion 34 (the cover portion 50) is elastically deformed, so that the cap 14 is allowed to rotate. be able to.
- the protruding portion 30 is provided on the outer peripheral surface of the proximal end side of the female luer 23, the engagement between the protruding portion 30 and the main body portion 34 is released only by slightly rotating the cap 14.
- the protrusion 30 and the main body 34 are engaged only in the initial stage of the opening operation, and thereafter the cap 14 can be rotated with a light operating force. it can. Therefore, the opening operation of the cap 14 is easy.
- the elastic member 32 rotates integrally with the main body portion 34 when the cap 14 is opened. For this reason, the elastic member 32 is reliably detached from the pressing portion 28 of the female luer 23 as the cap 14 rotates. Accordingly, the elastic member 32 does not stick to the pressing portion 28 of the female luer 23 and remains on the female luer 23 side.

It may be a chemical solution capable of dissolving or diluting the drug M. Note that the medical liquid L may not be prefilled in the prefilled syringe 80 as in the present embodiment, but may be aspirated from a vial or the like into an empty syringe as necessary.
- the medicine M is sucked from the outer cylinder main body 12 into the prefilled syringe 80, Mix in prefilled syringe 80 and dissolve or dilute. Thereby, the desired chemical
- a so-called pumping operation is performed in which the liquid mixed in the outer cylinder main body 12 is returned from the prefilled syringe 80 from which the drug M has been once sucked and sucked into the prefilled syringe 80 again. You may go.
- the gasket stopper 68 is attached to the base end portion (flange 24) of the outer cylinder main body 12, the gasket 16 does not come out from the outer cylinder main body 12 in the base end direction, and the base end of the outer cylinder main body 12 is removed.

Moreover, since the insertion part 37 of the cap 14 is inserted into the female luer 23, the medicine M is prevented from leaking when the male luer 82 is connected.
- the sealing portion 39 and the tip end surface of the female luer 23 are in close contact with each other, so The opening 23b is sealed in a liquid-tight manner. Therefore, according to the syringe outer cylinder 18 of the present invention, it is possible to ensure liquid tightness when the cap is not opened, prevent chemical leakage when the male luer is connected, and sterilize the inner peripheral surface 23a of the female luer 23. Is obtained.
- the pressing portion 28 crushes the sealing portion 39 once along the opening 23b, the pressing portion 28 and the sealing portion 39 are sufficiently in close contact with each other, and good sealing performance is obtained.
- the insertion part 37 and the sealing part 39 are formed by the integral elastic member 32, the part to be sealed is only one place, and good sealing performance can be obtained with a simple structure. .
- the main body portion 34 of the cap 14 has a rotation preventing portion 48 that prevents the elastic member 32 from rotating relative to the main body portion 34.
- the elastic member 32 can be prevented from sticking to the pressing portion 28 and remaining on the female luer 23 side.
- the rotation preventing portion 48 is inserted into the cylindrical portion 36 and engages with the inner peripheral surface 36a of the cylindrical portion 36, the relative rotation between the elastic member 32 and the main body portion 34 is effectively performed with a simple structure.

Therefore, relative rotation between the elastic member 32 and the main body 34 can be more effectively prevented.
- the female luer 23 is provided with the female side engaging portion 31 and the cap 14 is provided with the cap side engaging portion 51 (see FIG. 7), so that loosening of the cap 14 is preferably prevented. be able to.
- the cap side engaging portion 51 is formed at the proximal end portion of the cover portion 50, and the female luer 23 is formed to project from the outer peripheral surface of the proximal end portion of the female luer 23 in the radial direction. Since it has the protrusion part 30 which comprises the joint part 31, since engagement with the protrusion part 30 and the cover part 50 is cancelled
- the small distance portion 50b of the cover portion 50 that engages with the protruding portion 30 so as to prevent the cap 14 from loosening is obtained as a result of being deformed by receiving the force from the protruding portion 30. Therefore, the protrusion 30 and the cover 50 are engaged with each other with an accurate positional relationship. Therefore, it is not necessary to align the screwed structure between the cap 14 and the tube tip portion 22 and the protruding portion 30, and a loosening prevention structure for the cap 14 without backlash can be easily obtained.
