  DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below with reference to the drawings. In the following description regarding the connector, “upper and lower” and “left and right” refer to those in FIGS. 1, 2, 6, 7, 9, and 10.

<First Embodiment>
A first embodiment of the present invention will be described with reference to FIGS.

  The fluid connector according to the first embodiment has a female member 2 having a through hole 21 fixed to the opening of the container 1 and communicating in the axial direction, and one end (lower end) opening of the through hole 21 of the female member 2. The valve body 3 arranged so as to cover the fluid body 411 is inserted into the through hole 21 through the valve body 3 from one end (lower end) of the female member 2, and has a fluid passage 411 extending in the axial direction therein and the tip The male member 4 having a communication hole 412 communicating with the fluid passage 411 in the vicinity and the male member 4 inserted into the through hole 21 are separated from the opening of the other end (upper end) of the through hole 21 and the other end (upper end). A plug 5 is provided that opens the opening and reseals the opening of the other end (upper end) of the through hole 21 when the male member 4 is removed from the through hole 21.

  The female member 2 is made of a synthetic resin and has a substantially boat-shaped base portion 22 that is heat-sealed in the opening of the container 1 and a locking portion that protrudes from the upper end of the base portion 22 and has an annular inward convex portion 231 at the distal end portion. 23, an annular first flange portion 24 formed at the lower end of the base portion 22, a cylindrical portion 25 protruding from the lower end of the base portion 22, and an annular second flange portion 26 formed at the tip of the cylindrical portion 25. And. A medium diameter cylindrical wall 212 is formed in the middle of the height of the through hole 21. The inner diameter of the medium-diameter cylindrical wall 212 is formed to be slightly larger than the outer diameter of the large-diameter portion 414 of the rod-like portion 41 of the male member 4 described later. A large-diameter cylindrical wall 211 having a slightly larger inner diameter than the intermediate-diameter cylindrical wall 212 is formed on the lower end side of the intermediate-diameter cylindrical wall 212. The container 1 is preferably a flexible container such as a pouch.

  The plug 5 is a cap-shaped member integrally formed with the female member 2 and is connected to the base portion 22 of the female member 2 via two flexible left and right connecting portions. The inner surface of the peripheral wall of the plug 5 is gradually reduced in diameter toward the top wall. The lower half of the peripheral wall of the plug 5 is fitted into the locking portion 23 of the female member 2. An annular step 51 is formed in the middle of the height of the outer surface of the peripheral wall, and the tip of the locking portion 23 of the female member 2 is received by the annular step 51. On the outer surface of the lower end portion of the plug 5, an annular outer convex portion 52 that engages with the annular inner convex portion 231 of the locking portion 23 is formed. Further, an annular inward convex portion 53 is formed on the inner surface of the lower end portion of the plug 5.

  The valve body 3 is formed of an elastic body such as an elastomer or rubber as a material, is formed on the axis of the through hole 21 of the female member 2 and protrudes toward the through hole 21 side, and a radial direction thereof. It has an annular base portion 32 that is formed on the outer side and abuts against the second flange portion 26 that is the lower end portion of the female member 2.

  An openable / closable cross slit 33 through which the male member 4 penetrates is formed in the central portion of the valve portion 31. A central portion of the valve portion 31 is divided into four flaps by a slit 33. The lower surface side of the valve portion 31 is hemispherical, and the upper surface side is formed flat near the center, so that the thickness gradually decreases toward the central portion.

  An outer peripheral wall of the second flange portion 26 is fitted on the outer side of the annular base portion 32 in the radial direction, and an attachment portion 34 for attaching the valve body 3 to one end portion (lower end portion) of the female member 2 is formed. The attachment portion 34 has an attachment cylinder portion 341 provided upright on the annular base portion 32, and an attachment ring portion 342 is formed in the inner diameter direction at the tip of the attachment cylinder portion 341.

  An annular thin portion 35 is formed on at least one of the upper surface side and the lower surface side of the annular base portion 32. Preferably, an annular thin portion 35 is formed on the lower surface side of the annular base portion 32. This is because the lower surface side does not come into contact with the female member 2, so that the attachment of the valve body 3 to the female member 2 does not become unstable due to the unevenness of the annular base portion 32. Since the annular thin portion 35 is easier to expand and contract than the other portions of the annular base portion 32, the valve portion 31 can be mounted even if the attachment portion 34 is pulled outward in the radial direction and fitted into the peripheral wall of the second flange portion 26. Pulling outward in the radial direction can be prevented, and the slit 33 shape can be maintained.

  The male member 4 includes a rod-like portion 41 having a fluid passage 411 extending in the axial direction therein and having a communication hole 412 opened in the peripheral surface near the tip (upper end), and connected to the tip of the rod-like portion 41 and connected to the plug 5. And an engaging head 42. The male member 4 is made of synthetic resin or metal.

  The outer peripheral surface of the head 42 is gradually reduced in diameter toward the tip, and can be fitted into the plug 5. In addition, an annular groove 421 is formed on the outer surface of the base end portion of the head portion 42 so that the annular inward convex portion 53 of the plug 5 is locked.

  The distal end portion of the rod-shaped portion 41 is a small-diameter portion 413 having a slightly smaller diameter than the proximal end (lower) portion. A plurality of communication holes 412 are formed in the small diameter portion 413 at intervals in the circumferential direction. An annular groove 415 is formed above the large-diameter portion 414 in the rod-like portion 41, and a part of the O-ring 43 that seals between the rod-like portion 41 and the inner surface of the through hole 21 of the female member 2 is formed in this annular groove. It is inserted.

  Next, a method of using the fluid connector in the first embodiment will be described. For example, the case where the fluid as the contents is poured out from the container 1 will be described as an example. From the state shown in FIG. 1, first, the male member 4 is first inserted into the through hole of the female member 2 fixed to the opening of the container. The slit 33 of the valve body 3 is penetrated from one end portion (lower end portion) of 21 and inserted into the through hole 21. The head 42 of the male member 4 is fitted into the plug 5 that has been engaged with the locking portion 23 (the other end portion) of the female member 2, and then the plug 5 is pushed upward to lock the female member 2. Depart from part 23. When the male member 4 is further inserted into the through hole 21, it moves to a position where the communication hole 412 of the rod-like portion 41 faces the inside of the container 1. Thereby, the fluid can be poured out of the container 1 from the communication hole 412 through the fluid passage 411.

  At this time, the valve portion 31 is opened and closed by the male member 4 so as to rise in the insertion direction, and is bent upward along the through hole 21. The valve portion 31 is accommodated in a space sandwiched between the rod-like portion 41 of the male member 4 serving as an accommodating portion and the large-diameter cylindrical wall 211 of the through hole 21. The large-diameter cylindrical wall 211 is formed so that the valve portion 31 in a state along the large-diameter cylindrical wall 211 has substantially the same inner diameter as the medium-diameter cylindrical wall 212. Since the valve portion 31 is accommodated in the accommodating portion, the female member 2 and the male member 4 can be arranged on the concentric shaft, and the male member 4 and the plug 5 can be reliably engaged. In addition, since the male member 4 can be smoothly inserted and removed in the through hole 21, damage to the valve portion 31 by the male member 4 can be prevented.

  When the fluid has been dispensed, the male member 4 is pulled downward (outward). Then, the plug 5 is moved downward together with the head portion 42 of the male member 4, thereby engaging with the locking portion 23 of the female member 2, and the through hole 21 of the female member 2 is closed. Furthermore, when the male member 4 is pulled, its head 42 is detached from the plug 5, and the male member 4 is pulled out from the through hole 21. At this time, since the valve body 3 has a self-closing function, it is restored to its original shape. The valve portion 31 can be closed regardless of the orientation of the fluid connector. Thereby, when pulling out the male member 4 from the female member 2, the fluid adhering to the inner surface of the female member 2 does not drip and can be used without polluting the surroundings. Further, when a poor engagement between the plug 5 and the male member 4 occurs, fluid leakage can be prevented by the valve body 3.

  Fluid connectors are often used to contain consumables such as food, chemicals, cosmetics, pharmaceuticals, detergents, and industrial products, so they are strongly demanded to be inexpensive and never ignore the high manufacturing costs It is not possible. The fluid connector according to the present invention has a simple valve body structure, and can save space and cost.
