As shown in FIG. 9, a water discharge port 138 is perforated in the center of the front inner lid member 103 over the first layer 103A and the second layer 103B. A fuel discharge port 137 is perforated across the single layer 103A and the second layer 103B. The first layer 103A of the front inner lid member 103 is provided with a connecting hole 139, and the rear end except for the upper and lower ends of the connecting hole 139 is closed by the second layer 103B. A channel groove 134 is formed. The front channel groove 134 is continuously formed from a position overlapping the front end of the channel groove 121 to a position overlapping the front end of the channel groove 122, and is bent so as to avoid the water discharge port 138. The width is widened at a position corresponding to the outlet 132.

Similarly, a notch 136 is formed at the other end of the front channel groove 134 at the opposite edge, and the front channel groove 134 and the channel groove 122 communicate with each other through the notch 136. is doing.

  As shown in FIG. 10, since the front outer lid member 116 is overlaid on the first layer 103 </ b> A of the front inner lid member 103, the front channel groove 134 is covered with the front outer lid member 116, and is formed by the front channel groove 134. A flow path is formed. The front outer cover member 116 is perforated with a fuel discharge port 131, an air discharge port 132, and a water discharge port 133. A water discharge port 133 is formed at the center of the front outer lid member 116, and the fuel discharge port 131, the water discharge port 133, and the air discharge port 132 are arranged in a straight line along the width direction of the fuel container 100 in this order. Yes. The fuel discharge port 131 is opposed to the fuel discharge port 137 of the front inner lid member 103, and the water discharge port 133 is opposed to the water discharge port 138 of the front inner lid member 103.

  As shown in FIGS. 4 and 7, the fuel discharge port 131 and the air discharge port 132 penetrate from the rear surface of the front outer cover member 116 to the front surface. The periphery of each air discharge port 132 is provided in a nipple shape. The water discharge port 133 also penetrates from the rear surface to the front surface of the front outer lid member 116, but the periphery of the water discharge port 133 is provided flat.

  Even if an external force is applied to the hollow member 102, the fuel discharge port 131 and the fuel discharge port 137 require no fluid to flow out of the hollow member 102 through the fuel discharge port 131 and the fuel discharge port 137. A check valve 105 for blocking the flow is fitted. Specifically, the check valve 105 is a duckbill valve in which a material having flexibility and elasticity (for example, elastomer) is formed in a duckbill shape, and the check valve 105 has its duckbill tip on the inside of the hollow member 102. Is fitted into the fuel discharge port 131 and the fuel discharge port 137.

  The air discharge port 132 overlaps a midway between one end of the front flow channel 134 and the other end, and communicates with the midway of the front flow channel 134. The front channel groove 134 is provided so as to be wide at the position where the air discharge port 132 faces.

  The air discharge port 132 has a check valve 106 that prevents an unnecessary flow of fluid from the front channel groove 134 inside the fuel container 100 to the outside through the air discharge port 132 even when an external force is applied to the hollow member 102.

Specifically, the check valve 106 is a duckbill valve in which a flexible and elastic material (e.g., elastomer) is formed in a duckbill shape, and the check valve 106 has its duckbill tip on the inside of the hollow member 102. It is inserted into the air outlet 132 in a state of facing toward.

  The water storage port 110 and the water discharge port 138 are inserted so that the water storage pipe 110 penetrates, and one end of the water storage pipe 110 protrudes outside the front surface of the front outer lid member 116, The fuel discharge port 131 and the air discharge port 132 protrude to the same height. On the other hand, as shown in FIG. 2, a holding port 143 is perforated at the center of the first layer 104A and the second layer 104B of the rear inner lid member 104, and the other end of the water accommodation tube 110 is the first layer 104A. However, it does not reach the holding port 143 of the second layer 104B. Thereby, the water accommodation pipe 110 is constructed between the front outer lid member 116 and the rear inner lid member 104. In addition, vent holes 146 and 147 penetrating through the first layer 104A and the second layer 104B are formed on the left and right sides of the holding port 143 of the rear inner lid member 104, respectively.

  In the water containing pipe 110, near the end on the water discharge port 133 side, even if an external force is applied to the water containing pipe 110 through the hollow member 102, no fluid is required from the inside of the water containing pipe 110 toward the end opening.

Specifically, the check valve 107 is a duckbill valve in which a flexible and elastic material (e.g., elastomer) is formed in a duckbill shape, and the check valve 107 has a duckbill-shaped tip at the rear inner lid member 104. It is fitted in the water accommodation pipe 110 in a state directed toward the.

  FIG. 11 is a perspective view of the rear inner lid member 104 from the second layer 104B side. As shown in FIG. 11, the second layer 104 </ b> B of the rear inner lid member 104 is formed with openings that are continuously open to the holding port 143 on the left and right sides of the holding port 143, respectively. It coincides with the vent holes 146 and 147. The first layer 104 </ b> A of the rear inner lid member 104 is not opened in areas that do not overlap with the vent holes 146, 147, that is, between the holding port 143 and the vent hole 146 and between the holding port 143 and the vent hole 147. These unopened portions correspond to the bottom of the lateral groove 144 that communicates the holding port 143 and the vent hole 146 and the bottom of the lateral groove 145 that communicates the retainer port 143 and the vent hole 147, respectively.

  The second layer 104 </ b> B of the rear inner lid member 104 is further provided with another opening 152, and a rear channel groove 148 is formed with the first layer 104 </ b> A facing the opening 152 as the bottom. The rear flow channel 148 is continuously formed from a position overlapping the rear end of the flow channel 121 to a position overlapping the rear end of the flow channel 122, and is bent so as to avoid the holding port 143. In addition, a notch 149 is formed at one end of the rear flow channel 148 at the edge of the rear inner lid member 104, and the rear flow channel 148 and the flow channel are formed through the notch 149. The groove 121 communicates. Similarly, a notch 150 is formed at the other end of the rear channel groove 148 on the opposite edge, and the rear channel groove 148 and the channel groove 122 are interposed through the notch 150. Are communicating.

  As shown in FIG. 12, the rear outer lid member 117 is overlapped on the rear inner lid member 104, so that the rear channel groove 148 is covered with the rear outer lid member 117, and the channel by the rear channel groove 148 is formed. It is formed. As shown in FIGS. 2, 6, and 8, the rear outer lid member 117 has a first air inlet 141 and a second air inlet 142 drilled therein. The first air inlet 141 is formed at a position opposite to the fuel outlet 131, and the second air inlet 142 is formed at a position opposite to the air outlet 132.

  The first air inlet 141 penetrates from the front surface to the rear surface of the rear outer lid member 117. A vent hole 151 is formed in the rear inner lid member 104 at a position opposite to the first air inlet 141. Around the ventilation hole 151, the second layer 104B is projected in a nipple shape. The first air inlet 141 is fitted with a check valve 111 that prevents the flow of fluid from the hollow member 102 to the outside through the vent hole 151 and the first air inlet 141. Specifically, the check valve 111 is a duckbill valve in which a flexible and elastic material (e.g., elastomer) is formed in a duckbill shape, and the check valve 111 has its duckbill tip on the inside of the hollow member 102. Is fitted into the first air inlet 141 in a state directed toward the. An air chamber 153 located on the end side of the liquid fuel 114 and increasing in volume as the liquid fuel 114 is consumed, and an air chamber 153 located on the end side of the water 112 and increasing in volume as the water 112 is consumed. The chamber 154 has the same internal pressure because it communicates with each other via the vent holes 146, 147, the lateral grooves 144, 145 and the holding port 143 of the rear inner lid member 104. The check valve 111 allows air to enter from the outside of the fuel container 100 in order to buffer the pressure difference when the air pressure in the air chamber 153 and the air chamber 154 becomes significantly lower than the air pressure outside the fuel container 100. is there.

  The second air inlet 142 is formed in a rectangular shape. The second air inlet 142 overlaps a midway between one end of the rear flow channel 148 and the other end, and communicates with the midway portion of the rear flow channel 148. The rear flow path groove 148 is provided so as to be wide at the position where the second air introduction port 142 faces.

  The air filter 108 is fitted into the second air introduction port 142, and the second air introduction port 142 is closed by the air filter 108.

  As shown in FIGS. 3 to 8, the follower 113 is accommodated in the water accommodating tube 110 so as to be in contact with the end of the water 112 (on the rear inner lid member 104 side). Since the follower body 113 is in contact with the inner wall of the water accommodation pipe 110, the space in the water accommodation pipe 110 is partitioned by the follower body 113 into an area on the front inner lid member 103 side and an area on the rear inner lid member 104 side. Yes. The follower 113 is a liquid, sol, gel or the like having a low affinity for the water 112, and is a highly viscous liquid having a higher viscosity than the water 112 and insoluble in the water 112. Since the follower 113 has the property of a structural viscous fluid (abnormally viscous fluid) in which the apparent stress decreases as the shear stress (or shear rate) increases, the water 112 is discharged from the water discharge port 133. When the end of the water 112 on the rear inner lid member 104 side approaches the water discharge port 133 side, the follower 113 follows so that there is no gap between the end of the water 112. Thus, since the follower 113 closes the end of the water 112 in the water accommodation pipe 110, the water accommodation pipe 110 on the water discharge port 133 side has no gap due to air or the like as long as the water 112 remains. 112, the water 112 reaches the water discharge port 133 even if the fuel container 100 is tilted so that the water discharge port 133 is on the upper side. Therefore, the water 112 is easily discharged from the water discharge port 133. Cheap. Further, the follower 113 can suppress the volatilization of the water 112. As the follower 113, polybutene, liquid paraffin, spindle oil, other mineral oils, dimethyl silicone oil, methylphenyl silicone oil, other silicone oils, or combinations thereof can be used. In addition, since the check valve 107 is provided in the water storage pipe 110, the water 112 in the water storage pipe 110 is not unnecessarily leaked outside.

  In the hollow member 102, the follower 115 is accommodated so as to be in contact with the end of the liquid fuel 114 (on the rear inner lid member 104 side). Since the follower 115 is in contact with the inner wall of the hollow member 102, the space in the hollow member 102 is partitioned by the follower 115 into a region on the front inner lid member 103 side and a region on the rear inner lid member 104 side. The follower 115 is a liquid, sol, gel or the like having a low affinity for the liquid fuel 114, and is a highly viscous liquid that is higher in viscosity than the liquid fuel 114 and insoluble in the liquid fuel 114. Since the follower 115 has the property of a structural viscous fluid (abnormally viscous fluid) in which the apparent stress decreases as the deviation stress (or deviation speed) increases, the liquid fuel 114 is discharged from the fuel discharge port 131. When the end of the liquid fuel 114 on the rear inner lid member 104 side approaches the fuel discharge port 131 side, the follower 113 follows so that there is no gap between the end of the liquid fuel 114. Thus, since the follower 113 closes the end of the liquid fuel 114 in the hollow member 102, there is no gap due to air or the like in the water accommodation pipe 110 on the fuel discharge port 131 side as long as the liquid fuel 114 remains. Since the liquid fuel 114 is filled, the liquid fuel 114 reaches the fuel discharge port 131 even if the fuel container 100 is tilted so that the fuel discharge port 131 is on the upper side. 114 is easy to discharge. Further, the follower 115 can suppress the volatilization of the liquid fuel 114. Specifically, polybutene, liquid paraffin, spindle oil, other mineral oils, dimethyl silicone oil, methylphenyl silicone oil, other silicone oils, and combinations thereof can be used as the follower 115. Since the check valve 105 is provided in the fuel discharge port 131, even if an external force is applied to the hollow member 102 in this state, the liquid fuel 114 in the hollow member 102 does not leak unnecessarily.

  The air chamber 153 from the rear inner lid member 104 is connected to the rear opening of the water accommodation pipe 110 through the vent holes 146 and 147 and the lateral grooves 144 and 145 of the rear inner lid member 104 rather than the follower 115.

  The container body 101 configured as described above is packaged by the packaging material 159. The packaging material 159 is formed of a synthetic resin that does not sufficiently transmit air. The packaging material 159 is preferably packaged by vacuum suction inside the container body 101.

  The packaging material 159 includes a body winding portion 159g wound around the waist of the hollow member 102, and a first ear that extends forward from the body winding portion 159g and seals the front end surface of the container body 101 (the front surface of the front outer lid member 116). And a second ear portion 159i that extends rearward from the body winding portion 159g and seals the rear end surface of the container main body 101 (the rear surface of the rear outer lid member 117). The first ear portion 159h covers the fuel discharge port 131, the air discharge port 132, and the water discharge port 133, and the second ear portion 159i covers the first air introduction port 141 and the second air introduction port 142. .

  A cut line 159e along the front edge of the front outer lid member 116 is formed between the body winding part 159g and the first ear part 159h, and between the body winding part 159g and the second ear part 159i, A tear line 159f is formed along the edge of the rear surface of the rear outer lid member 117. By cutting the packaging material 159 along the cut line 159e, the first ear portion 159h can be easily separated from the body winding portion 159g, and by cutting the packaging material 159 along the cut line 159f, the second ear portion 159i. Can be easily separated from the body winding portion 159g. The body winding portion 159g includes the outer surface of the hollow member 102, the edge of the front outer lid member 116, the edge of the rear outer lid member 117, the edge of the first layer 103A of the front inner lid member 103, and the second of the rear inner lid member 104. It is preferable to adhere to the edge of the layer 104B.

  Since the container body 101 when not in use is sealed by the packaging material 159, it is possible to prevent the discharge of the liquid fuel 114 from the fuel discharge port 131 or the discharge of the water 112 from the water discharge port 133 in advance. Since the air filter 108 is not exposed at the second air inlet 142, deterioration of the filter can be prevented.

  When connecting the container main body 101 to a fuel cell or a unit having a fuel cell so that water 112 and liquid fuel 114 can be supplied from the container main body 101 to the fuel cell or the like, the cut line 159e is pulled by pulling the first ear 159h. The first ear part 159h is cut off from the body winding part 159g along and the fuel discharge port 131, the air discharge port 132, and the water discharge port 133 are exposed. Similarly, by pulling the second ear portion 159i, the second ear portion 159i is separated from the body winding portion 159g along the cutoff line 159f, and the first air introduction port 141 and the second air introduction port 142 are exposed. Thereafter, the container main body 101 with the trunk winding portion 159g left is set in a fuel cell or a unit having a fuel cell.

  As described above, when the container body 101 is not used (shipped), the front surface of the front outer lid member 116 and the rear surface of the rear outer lid member 117 are covered with the packaging material 159. Further, as shown in FIG. 13, a slight cut is made in a part between the body winding part 159g and the first ear part 159h, and the end part is along the periphery of the front outer lid member 116 so as to overlap the cut. The first ear portion 159h may be peeled off by providing a cutting guide tape 160 and pulling the cutting guide tape 160 in the peripheral direction of the front surface of the front outer lid member 116. It is desirable that a cut line 159e is provided under the cut guide tape 160 so that the flow channel grooves 121 and 122 are not exposed.

  Then, a slight notch is made in a part between the body winding part 159g and the second ear part 159i, and the cutting guide tape 161 is formed along the peripheral edge of the front surface of the rear outer lid member 117 so that the end part overlaps the notch. And the second ear 159i may be peeled off by pulling the cutting guide tape 161 in the peripheral direction of the rear outer lid member 117. It is desirable that a cut line 159f is provided under the cut guide tape 161 so that the flow channel grooves 121 and 122 are not exposed.

  Further, instead of the packaging material 159, the container body 101 may be packaged with a packaging material 259 as shown in FIG. The packaging material 259 is formed of a synthetic resin that does not sufficiently transmit air. The packaging material 259 preferably wraps the container body 101 by vacuum suction inside.

  The packaging of the fuel container 100 with the packaging material 259 having the structure shown in FIG. 14 is performed by the following steps. As shown in FIG. 15, the packaging material 259 is wound around the waist of the hollow member 102 so that the gaps in the channel grooves 121 and 122 are not crushed, and the body winding portion 259 g of the packaging material 259 is brought into close contact with the outer surface of the hollow member 102. . Then, the pair of ears 259a and 259a on the short side extending from the front surface of the front outer lid member 116 is preceded and folded inward, and then the pair of ears 259b and 259b on the long side is folded in the ear.
