Containers that prevent exposure to water are known.

  For example, when a known container is squeezed to the outer layer, the air between the outer layer and the inner layer is not discharged to the outside, but only the contents of the inner layer are discharged. It is configured so that air between the outer layer and the inner layer is introduced by the restoring force and does not enter the inner layer. For this reason, a check valve mechanism for air between the outer layer and the inner layer and a reverse mechanism for the contents of the inner layer are provided. A valve stop mechanism provided in a cap is known (see, for example, Patent Document 1).

In this known container, the inner stopper fitted to the mouth tube portion of the container main body and the valve body arranged between the inner stopper and the cap are separated and provided in the inner stopper. A check valve mechanism for the contents of the inner layer is constituted by the discharge port and the valve body of the contents, and a check valve mechanism for the air between the outer layer and the inner layer is constituted by the suction port and the valve body provided in the cap, respectively. Yes.
Then, the tip of the opening of the spout has a structure similar to that of the known stopper of the container, so that the spout-containing container in which the insertion container having the spout is accommodated in the outer container is obtained. It is conceivable to use a spout storage container that can introduce air between the containers.

  The air valve body 162 of the tip flange portion 161 of the spout 160 is integrally formed so as to act as a valve by elastic deformation, and operates as a check valve by being pressed against the air valve seat 146 of the cap 130. Thus, even if the accuracy of the shape and position of each constituent member is low, the air valve body 162 of the spout 160 is elastically fitted to the inner peripheral surface of the air valve seat 146 of the cap 130 so that they can be aligned. Sealing performance is ensured. Further, since the air valve body 162 can be sealed even if the position of the cap 130 in the vertical direction is slightly shifted, it is possible to prevent deterioration of the sealing performance with time due to external force or vibration.

  The holding outer frame 151 of the inner plug 150 is closely fitted to the inner peripheral surface of the fixed wall portion 164 of the tip flange portion 161 of the spout 160, and the tip flange portion 161 is fixed to the upper outer peripheral side of the holding outer frame 151. An engaging jaw portion 154 sandwiched between the wall portion 164 and the upper holding convex portion 141 of the cap 130 described above is provided. With this configuration, the spout 160 and the inner plug 150 are internally fixed in the cap 130 by fitting the cap 130 to the mouth tube portion 120 of the outer container 112. This facilitates the assembly work for holding the spout 160 and the inner plug 150 inside the skirt wall 140 of the cap 130.

The operation and operation of the spout storage container 100 according to the first embodiment of the present invention configured as described above will be described with reference to FIGS. 1, 6, and 7.
First, the inner plug 150 is placed on the inner peripheral surface of the fixed wall portion 164 of the front end flange portion 161 of the spout 160 in a state where the insertion vessel 111 is accommodated in the outer container 112 and the contents are filled in the insertion vessel 111. As shown in FIG. 1, the cap 130 in a state where the cut portion 134 is not cut is fitted to the mouth tube portion 120, and the upper end of the mouth tube portion 120 and the upper holding convex portion 141 of the cap 130 are fitted. In between, the front-end | tip flange part 161 of the spout 160 and the engaging jaw part 154 of the inner plug 160 are pinched and fixed. At this time, the opening 165 of the spout 160 is designed to push the central valve body 152 of the inner plug 150 slightly upward, so that the central valve body 152 is always open by the elasticity of the elastic arm 155. It becomes possible to act reliably as a check valve.

  Moreover, since the pressing convex part 139 provided below the cutout part 134 is formed so as to press the pressed part 156 of the central valve body 152, the central valve body 152 is opened by pressure when not in use. Even if pressure is applied from the outside during transportation or storage, or the internal pressure rises due to temperature changes, etc., the check valve does not operate and the contents are prevented from leaking to the top of the central valve body 152 it can. In addition, the engaging jaw portion 154 of the inner plug 150 is pressed against the upper holding convex portion 141 provided on the cap 130 by the push-up. Thus, the upward air flow from the upper end of the holding outer frame 151 is prevented.

  When the contents are poured out from the opening from which the cut portion 134 has been cut, as shown in FIG. 6, it is deformed from the outside, for example, by firmly grasping the outer container 112 with the upper lid 133 opened. Apply pressure inside. At this time, the air existing between the outer container 112 and the insertion container 111 is pressurized, and through the through hole 163 of the spout 160, the front end flange portion 161 of the spout 160, the cap 130, and the engaging jaw portion 154 of the inner plug 150. The air in the space surrounded by is also pressurized.

At this time, the front flange portion 161 of the spout 160, the engaging jaw portion 154 of the inner plug 150, the engaging jaw portion 154 of the inner plug 150, and the upper holding convex portion 141 of the cap 130 are sealed, respectively. The flange portion 161 and the cap 130 are sealed by the air valve body 162 provided on the outer peripheral side of the upper end flange portion 161 being pressed against the air valve seat 146 of the cap 130 to act as a check valve.
For this reason, the pressurized air does not flow out, and the pressure acts only as a force for pushing out the contents in the insertion container 111. The content in the insertion container 111 that has been subjected to pressure pushes up the central valve body 152 of the inner plug 150 that closes the opening 165 against the elasticity of the elastic arm 155 as shown by the black arrow. Poured out.

  When stopping the pouring, the deformation of the exterior container 112 from the outside is released. At this time, since the outer container 112 tends to return to its original shape due to elasticity, the air existing between the outer container 112 and the insertion container 111 becomes negative pressure, and the mouth tube portion of the outer container 112 passes through the through hole 163. 120, the air in the space surrounded by the tip flange 161 of the spout 160, the cap 130 and the engaging jaw 154 of the inner plug 150 also has a negative pressure.

At this time, as shown in FIG. 7, the air valve body 162 provided on the outer peripheral side of the top flange portion 161 that sealed the cap flange 130 and the tip flange portion 161 of the spout 160, as shown by white arrows, Air that is separated from the air valve seat 146 of the cap 130 by the negative pressure and passes through the notch groove 145 provided in the skirt wall 140 is introduced, passes through the through-hole 163, and between the exterior container 112 and the insertion container 11. Air flows into the space. Moreover, although the content of the insertion container 111 also becomes a negative pressure, the force by which the central valve body 152 of the inner stopper 150 pushes up against the elasticity of the elastic arm portion 155 is released by the negative pressure, and the central valve body 152 is Since the opening 165 is closed and acts as a check valve, air does not flow into the insertion container 111.
In FIG. 7, the air valve body 162 is illustrated so as to be largely separated from the air valve seat 146 for the sake of explanation. However, it is sufficient that air passes by a negative pressure and a slight gap may be formed. .

An opening for taking out contents is formed at the inner end of the top wall 244 of the cap body 231.
An air valve seat 246 is provided on the inner peripheral surface of the skirt wall 240 on the top wall 244 side so that the air valve body 262 elastically contacts and constitutes a check valve mechanism. An opening for pouring the contents is formed in the center of the top wall 244, and a pouring cylinder portion 236 for smoothly pouring the contents upward is formed on the outer peripheral side of the opening.

  The inner peripheral surface of the extraction tube portion 236 extending upward from the upper surface of the top wall 244 is in close contact with the outer peripheral surface of the sealing wall portion 237 that hangs down from the inner surface of the top surface wall 232 of the upper lid 233 and is sealed. Further, a pressing projection 239 that presses the central valve body 252 toward the mouth tube portion 220 is formed at the center of the lower surface of the upper lid 233.

  Only the peculiar action and operation of the spout storage container 200 according to the second embodiment of the present invention configured as described above will be described.

The spout storage container 200 according to the second embodiment is unused because the pressing protrusion 239 provided at the center of the lower surface of the upper lid 233 is formed so as to press the pressed portion 256 of the central valve body 252. When the upper lid 233 is closed at any time after the start of use, the central valve body 252 can be prevented from opening due to pressure.
Therefore, even after the start of use, even if pressure is applied from the outside during transportation or storage, or the internal pressure rises due to a temperature change or the like, the check valve does not operate, and the contents remain above the central valve body 252. Can be prevented from leaking.

  The spout storage type container of the present invention is easy to manufacture and assemble, improves the sealing performance, does not deteriorate the sealing performance over time, and allows the cap to be provided with a large opening virgin seal. Only the insertion container is deformed due to the reduced pressure, and air is introduced between the outer container and the insertion container to prevent a change in the outer shape of the container, and the contents of the insertion container are exposed to the air. Therefore, it is possible to suitably use contents that require gas barrier properties, such as chemicals, pharmaceuticals, and foodstuffs, as containers that are used to repeatedly pour and store an appropriate amount.
