[Embodiment]
Hereinafter, a first embodiment, which is a specific example of the present invention, will be described with reference to the drawings.

  Drawing 1 is a mimetic diagram showing nozzle 10 for oil supply concerning a 1st embodiment, and gasoline carrying can 1 which attaches it. As shown in FIG. 1, the refueling nozzle 10 is attached to the gasoline carrying can 1 and provides a flow path when the gasoline stored in the gasoline carrying can 1 is poured out.

  FIG. 2 is a schematic side view of the oil supply nozzle 10. The oil supply nozzle 10 includes a main body portion including a spout portion 101, a flow rate adjustment portion 102, and a bellows-like portion 103, and an attachment portion 104. For example, the oil supply nozzle 10 is made of polyethylene and the mounting portion 104 is made of ABS.

  The spout part 101, the flow rate adjusting part 102 and the bellows-like part 103 form a flow path when gasoline is poured out from the gasoline carrying can 1, and the attachment part 104 is the spout part 101, the flow rate adjusting part 102 and the bellows-like part. It plays the role of watertightly attaching the main body 103 made of 103 to the gasoline carrying can 1.

  The mounting portion 104 has, for example, a threaded valley inside, and is on the outer surface of a cylindrical projection that forms a gasoline pouring port of the gasoline carrying can 1 with the body portion of the fueling nozzle 10. It is attached to the gasoline carrying can 1 by being screwed into the screw thread cut into two.

  The spout part 101 is a circular tube.

  The bellows-like portion 103 has a hollow bellows shape, and the user can flexibly change the shape by applying a small force. Therefore, the user can adjust the direction of pouring gasoline by changing the direction of the axis.

  In FIG. 3, the flow rate adjusting unit 102 is disposed between the spout unit 101 and the bellows unit 103 and connects them to each other.

  FIG. 3 is a cross-sectional view of the flow rate adjusting unit 102 cut along a plane perpendicular to the axial direction, that is, the gasoline flow path direction. FIG. 3A is a cross-sectional view of the flow rate adjusting unit 102 in a state where crushing described later is not performed, and FIG. 3B is a cross-sectional view of the flow rate adjusting unit 102 in a state where crushing is performed.

  As shown in FIG. 3 (a), the flow rate adjusting unit 102 is generally a square tube in a state where the crushing is not performed, but in each of a pair of two side surfaces facing each other in the axial direction (that is, gasoline). A crease 105 extending in parallel with the direction of the flow of the gas) is provided, and the wall surface is bent along the crease 105 to the inside of the tubular body, and a pair of wall surfaces are slightly recessed when viewed from the outside.

  Since the fold 105 is provided in this way, when the user presses the two side surfaces of the flow rate adjustment unit 102 that are not provided with the fold 105 out of two pairs of side surfaces facing each other during refueling, The flow rate adjusting unit 102 is crushed along a fold 105 provided on two side surfaces different from the two side surfaces, and the cross-sectional area thereof is reduced.

  More specifically, as shown in FIG. 3 (b), when the user presses in the direction of the arrow shown in FIG. 3 (a), the two opposed opposing sides approach each other so as to snuggle up, The two opposing side surfaces that are not pressed bend inward along the fold 105 provided in them. As a result, the cross-sectional area of the oil supply nozzle 10 in the flow rate adjusting unit 102 is reduced, and the flow rate of gasoline flowing therethrough is reduced.

  The user can change the cross-sectional area by adjusting the strength of pressing to crush the flow rate adjusting unit 102. If the cross-sectional area is reduced, the flow rate of gasoline flowing therethrough is reduced. Accordingly, when the user pours gasoline from the gasoline carrying can 1 into another container or the like, the flow rate of the gasoline flowing through the cross-sectional area can be easily and quickly adjusted by adjusting the crushing force of the flow rate adjusting unit 102. Can be adjusted.

  Therefore, according to the refueling nozzle 10, the flow rate of the gasoline can be instantaneously reduced by crushing the flow rate adjusting unit 102 with the user's finger, so that it is desired to pour gasoline up to the full capacity of the gasoline refueling destination container. Even in such a case, there was no risk of gasoline spilling out of the container due to overcapacity, and it could not be realized with the oiling nozzle according to the prior art that gasoline could be poured vigorously until the end of refueling It becomes possible.

  By the way, in the case of the oil supply nozzle 10 according to the above-described first embodiment, after repeated use, the flow rate adjusting unit 102 is crushed along the fold 105 and is crushed by the user. Even in a state where it is not broken, a state may occur in which the cross-sectional area is not sufficiently widened. In that case, there arises a disadvantage that a sufficient flow rate cannot be obtained even when gasoline is to be poured out vigorously.

  A specific example of the present invention provided with a device for reducing such a problem will be described below as a second embodiment.

  FIG. 4 is a photograph showing the entire oil supply nozzle 20 according to the second embodiment. Compared with the oil supply nozzle 10 according to the first embodiment, the oil supply nozzle 20 includes a first high-rigidity part 2061 between the spout part 101 and the flow rate adjustment part 102, and a bellows-like part 103 and a flow rate adjustment part. The second high-rigidity portion 2062 is provided between the first and second high-rigidity portions 2062.

  FIG. 5 is a photograph showing the first high-rigidity portion 2061 and the second high-rigidity portion 2062 included in the fueling nozzle 20 together with the periphery thereof. 5A to 5C show the same fueling nozzle 20 rotated at different angles around an axis whose axis is the gasoline flow rate direction so that the shape thereof can be seen.

  As shown in FIGS. 5A and 5B, the first high-rigidity portion 2061 has a component portion having one shape obtained by dividing a sphere into eight parts, and the flow rate adjustment portion 102 provided with the fold 105 is provided. In the connecting portion between the pair of wall surfaces and the spout portion 101, the one-eighth sphere-shaped component portion is connected to the wall surface of the flow rate adjusting portion 102 that is recessed inwardly in a state of protruding outward. . Similarly, the second high-rigidity portion 2062 has a component portion having one shape obtained by roughly dividing the sphere into eight parts, and a connection between the pair of wall surfaces of the flow rate adjustment portion 102 provided with the fold 105 and the bellows-like portion 103. In the portion, the one-eighth sphere-shaped constituent part is connected to the wall surface of the flow rate adjusting part 102 that is recessed inward in a state of being convex outward. These components having a one-eighth sphere shape have rigidity higher than that of the flow rate adjusting unit 102 due to the shape thereof, so that the shape does not change much by the user's pressing against the flow rate adjusting unit 102.

  Therefore, as shown in FIG. 4B, when the flow rate adjusting unit 102 is crushed by the user and then released from the pressure by the user, the flow rate adjusting unit 102 has a restoring force that the flow rate adjusting unit 102 itself has. In addition to the above, the push-open force due to the high rigidity of the first high-rigidity portion 2061 and the second high-rigidity portion 2062 returns to the state of FIG.

  As a result, according to the fueling nozzle 20, for example, the deformation wrinkle after the same number of times of crushing is smaller than the fueling nozzle 10 according to the first embodiment. Therefore, the fueling nozzle 20 can withstand a greater number of uses than the fueling nozzle 10.

Furthermore, for example, when the cross section is a hollow triangle, it is sufficient that only one fold 105 is provided on any of the three side surfaces. As described above, the number of folds 105 and the arrangement thereof can be variously changed.

  Further, in the above-described embodiment, the fold 105 of the flow rate adjusting unit 102 is provided so that its top faces inward when it is crushed, but the fold is so formed that its top faces outward. It may be configured.

  In addition, although the oil supply nozzle 10 concerning embodiment mentioned above is a liquid supply nozzle used for the carrying can for gasoline, it cannot be overemphasized that the liquid of the use object of the liquid supply nozzle concerning this invention is not restricted to gasoline.
