Description of the invention (12) As shown in FIG. 4, the 'return check valve (40) is interposed between the hollow needles (30), and its structure is the same as that of the air discharge portion (56) of the first embodiment. : That is, on the end surface adjacent to the toilet check valve (40), as shown in Fig. 4, < female touch > 7 丨 "Di has milk holes (57) 'The exhaust hole (57) is made of air The discharge shim (58) is plugged. On the other hand, a portion adjacent to the discharge port (36) of the air discharge portion (56) is provided with a liquid discharge filter (59) to plug the discharge port. In the liquid guide (60) of the third embodiment, the air discharge portion (66) is provided with an air discharge port (67) as shown in FIG. 6 and the liquid discharge filter (69) is for liquid According to the third embodiment, the outlet (36) can be covered with the cover (2a), and the air outlet (67) can also be covered. Therefore, during storage and storage, When a liquid container connector is not used, foreign matter or air can be prevented from being mixed in from the air discharge port (6 7), and the contents of the liquid container can be prevented from leaking out.

\\ 312 \ 2d-code \ 90-09 \ 90115730.ptd Page 15 503105 V. Description of the invention (13) The need for sex. Examples of the raw material for the filter sheet for air discharge include polypropylene, polyethylene, polyester, polytetrafluoroethylene, and po1yviny1idensifuoride. Since the resin film is hydrophobic and has extremely low water and moisture permeability, the possibility of accidentally leaking the contents of the liquid container to the outside is extremely low. In addition, since there are numerous fine pores in the resin film, the bubbles remaining in the contents can be passed through the load of the contents of the liquid container. The pores of the resin film constituting the filter for air discharge are preferably fine pores having a diameter of 0.2 to 120 μm, and those having a diameter of 0.5 to 1 5 // m are more suitable. If the diameter of the fine pores is smaller than the aforementioned range, it is difficult to discharge air. On the other hand, if the diameter exceeds the aforementioned range, the contents of the liquid container may leak. The thickness of the resin film constituting the air-exhaust filter is not particularly limited, and although it depends on the raw materials used, it is usually set within a range of 10 to 2000 mm. If the resin film is too thick, the air discharge property will be deteriorated. On the other hand, if the thickness is less than the above range, the strength may be lowered to affect production, or damage may occur during the liquid discharge operation. In this case, if a suitable non-woven laminate is applied to the resin film to increase its strength, # can be used. ~ • Liquid discharge filters The liquid guides (20), (50), and (60) of the above-mentioned third embodiment are provided more than the air discharge filters (28), (58), ( 68) Further downstream

C: \ 2D-CODE \ 90-09 \ 90ll5730.ptd Page 16 503105 V. Description of the invention (14) Filters for liquid discharge (29), (59), (69), which have excellent water permeability and Gas-shielding resin film. The purpose of the liquid discharge filter is to prevent bubbles contained in the liquid container (100) and the like from being discharged together with the contents of the liquid container (100). Therefore, there is a demand for the aforementioned good water permeability, and on the other hand, there is also a demand for good gas barrier properties (lack of gas permeability). Examples of the raw material for the liquid discharge filter include cellulose-based filters such as cellulose acetate, polyblocks (P 0 1 y SU 1 f one), and hydrophilically treated polytetrafluoroethylene (for example, G0ATECKS company's trade name "G0ATECKS", etc.), hydrophilic treated (polyvinylidensifluoride) (for example, MILIP0RE company's trade name "DURAP0RE"), and so on. The resin film mentioned above contains a large number of hydrophilic groups in the molecule, and also contains countless fine pores. Therefore, the contents of the liquid container can be easily passed through by the load of the contents of the liquid container. The pores of the resin film constituting the liquid discharge filter are preferably small pores having a diameter of 0.2 to 20 // m, and those having a diameter of 0.5 to 15 μm are more suitable. If the diameter of the fine pores is smaller than the aforementioned range, it is difficult to discharge the liquid. On the contrary, if the diameter exceeds the aforementioned range, there is a concern that air may leak out. The thickness of the resin film constituting the liquid discharge filter is not particularly limited. Although it depends on the raw materials used, it is usually set within a range of 10 to 2000 m. If the resin film is too thick, the discharge property of the liquid becomes poor. On the other hand, if the thickness is less than the above range, the strength may be lowered to affect production, or damage may occur during the liquid discharge operation. In this case, it is possible to use a suitable nonwoven fabric laminated on the resin film to increase its strength.

In addition, in FIG. 5 (a), the shape of the compression deformation state of the valve body (4 2) is shown by a dashed line. The above check valve, if a liquid container (not shown) is connected to the upstream U end of the check valve (40) When a fluid pressure P is applied to the valve body (4 2) from the open end (embedding port, not shown) of the guide body from the liquid container, the valve body (4 2) is compressed and deformed to open the communication hole (41a). . As a result, a gap portion (4 4) is formed between the valve seat (40) and the valve body (4 2), and the liquid is guided to the downstream D end of the check valve (40) through the gap portion (4 4). On the other hand, if the fluid pressure P is stopped, the compression-deformed valve body (42) returns to its original state, the communication hole (41a) is closed, and the gap portion (44) is eliminated. At this time, the valve body (4 2) is to be restored The direction of the original state (coaxial with the direction of the IL body pressure P and the direction opposite to the fluid pressure p) and the path through which the liquid flows countercurrently 逆
