  Next, the lid 4 will be described. As shown in FIG. 7A, the lid 4 has a substantially cylindrical shape with a bottom whose upper base is sealed by a head 43 and whose lower base is open. The peripheral portion of the head 43 extends in the outer diameter direction to form a collar portion 45. When the collar portion 45 is formed on the head portion 43, the discharge container 1 (the discharge container 1 in the state shown in FIG. 1) in which the discharge port 31 is closed by the lid body 4 is placed on the lower side. And can be placed stably.

  A bar-like portion 41 for sealing the discharge port 31 is provided at the center of the lower surface (inner surface) of the head 43 so as to protrude downward. As shown in FIG. 3, the rod-like portion 41 protrudes inside the discharge port 31 in a state where the discharge port 31 is closed by the lid 4. The height of the rod-like portion 41 (downward height from the lower surface of the head 43) is, for example, 2 to 30 mm.

In the process of closing the discharge port 31 with the lid 4, the rod-like portion 41 is configured to form a communication path that connects the inside and the outside of the discharge device 3.

Since the introduction guide 44 is provided, the distal end portion 33 (discharge port 31) of the discharger 3 is guided toward the rod-like portion 41 by the introduction guide 44 in the process of closing the discharge port 31 by the lid 4. It has become.

As shown in FIG. 3, the vertical cylindrical portion 42 forming the side wall of the lid body 4 has a size and a shape that can completely surround the barrel portion 34 of the discharger 3 from the side. Therefore, in a state where the discharge port 31 is closed by the lid 4, the vertical cylinder portion 42 is configured to cover the trunk portion 34 and the lower end portion of the vertical cylinder portion 42 reaches the base portion 32.
The height of the vertical cylinder part 42 is, for example, 26 to 71 mm. The cross-sectional area inside the vertical cylinder portion 42 is, for example, 28 to 315 mm ² .

An inner wall projection 42B is provided on the inner wall 42A of the vertical cylindrical portion 42. The inner wall protrusion 42B protrudes in the inner diameter direction over the entire circumference of the inner wall 42A. The vertical position of the inner wall projection 42 </ b> B is, for example, in the range of 0 to 10 mm from the lower end portion of the vertical cylinder portion 42.
In the present embodiment, an inner wall recess 42C is formed to be recessed in the outer diameter direction on the lower end side of the inner wall 42A of the vertical cylindrical portion 42, and an inner wall projection 42B is formed so as to protrude from the inner wall recess 42C.

As shown in FIG. 3, the outer wall 32 </ b> A of the base portion 32 and the inner wall 42 </ b> A of the vertical cylindrical portion 42 abut each other in a state where the discharge port 31 is closed by the lid body 4. Specifically, the outer wall protrusion 32B and the inner wall protrusion 42B are abutted.
Further, the base 32 is sandwiched between the upper end portion of the opening portion 21 and the lower end portion of the vertical cylinder portion 42 in a state where the discharge device 3 is fitted to the container body 2 and the discharge port 31 is closed by the lid body 4. It has become.

The container main body 2 accommodates an object, and the opening 21 is sealed with a cap C as shown in FIG. The lid 4 is attached to the discharger 3.
First, the cap C is removed from the opening 21 of the container body 2, and the opening 21 is opened as shown in FIG. Next, as shown in FIGS. 1 and 3, the base portion 32 of the discharger 3 with the lid 4 attached is fitted into the opening 21.
As a result, the inner peripheral edge of the opening 21 of the container body 2 is sealed by the inner cylinder 51 of the discharger 3. The upper end of the opening 21 is sealed by the downward rib 53 of the discharger 3. The outer peripheral edge of the opening 21 is sealed by the outer cylinder 52 of the discharger 3. The outer cylinder convex portion 52 </ b> B functions as a stopper for removing the discharger 3 from the opening 21.

Thus, after fitting the discharger 3 to the container body 2 and integrating them, the lid 4 is removed from the discharger 3, and the discharge port 31 of the discharger 3 is opened as shown in FIG. Then, the contents stored in the container body 2 are moved into the body 34 of the discharger 3 with the discharge port 31 facing downward or sideways. Furthermore, the body part 34 of the discharger 3 can be pressed from the lateral direction, and an appropriate amount of the contents accommodated in the body part 34 of the discharger 3 can be discharged from the discharge port 31.
When all the contents are used up or when the contents are not storable, the used discharge container 1 may be discarded. In the case where a stored item remains, the discharge port 31 may be resealed with the lid 4 and the discharge container 1 may be stored until it is used again.

Therefore, even if the air pressure in the storage space of the container main body 2 and the discharge device 3 is high, the rod-like portion 41 is pulled out from the storage space of the discharge device 3 as the lid body 4 is removed from the discharge port 31, The volume of the rod-shaped part 41 which occupies storage space reduces gradually. Accordingly, the air existing in the accommodation space is gradually expanded, and the pressure in the accommodation space is gradually reduced. As a result, when the lid 4 is removed from the discharger 3 and the discharge port 31 is opened, the contents remaining in the vicinity of the discharge port 31 of the discharger 3 are unlikely to overflow from the discharge port 31 and liquid dripping occurs. Hateful.

  On the other hand, the rod-like portion 41 is configured such that a communication path that connects the inside and the outside of the discharge device 3 is formed in the process of closing the discharge port 31 by the lid 4. In the present embodiment, a communication path forming groove 41A extending in the length direction is provided on the outer surface of the rod-like portion 41, and the communication path is formed from the communication path forming groove 41A. Therefore, in the process of closing the discharge port 31 by the lid body 4, the inside and the outside of the discharge device 3 communicate with each other through the communication path, so that the container body 2 resulting from closing the discharge port 31 by the lid body 4. And the rise of the atmospheric pressure in the accommodation space of the discharger 3 can be prevented or reduced. From such a point, the rise in the atmospheric pressure in the storage space of the container body 2 and the discharger 3 is prevented or reduced in advance.
