The nozzle hole is provided on one side, and the outside air suction hole is provided on the other side so that the liquid can be poured out when the container is tilted.

[0003]

[Problems to be solved by the device]

 In the conventional fluid pouring cap in which a through hole is formed on the left and right of the top of the cap, one of which is used as a nozzle hole and the other of which is used as an outside air suction hole, since the nozzle hole remains open, dust, etc. enter. There was an easy drawback.

The present invention makes it possible to open and close the nozzle hole easily and reliably.

[0005]

[Means for Solving the Problems]

 From the left and right side surfaces of the upper end surface of the nozzle 4 provided on the cap top wall, the elastic side plates 5, 5 are made to taper in a manner that expands upward and outward, and the elastic top plate is arched between the upper ends of these side plates. 7 is installed between the lower ends of the both side plates and the joint between the side plate and the top plate, or between the joint and the left and right central portions of the top plate and the left and right portions of the top plate. Refraction lines 8 and 9 are provided, and the lower surface of the central portion of the top plate 7 is formed so as to open and close the upper end opening surface of the nozzle by elastic inversion of the plate portion between these two refraction lines.

[0006]

[Embodiment of device]

 First, the first embodiment shown in FIGS. 1 to 4 will be described. 1 is a top wall of a cap, and an outer peripheral wall 2 to be fitted to the outer surface of the neck of the container body is hung from the outer periphery of the top wall, and A small gap is provided between the inner peripheral wall 3 and the outer peripheral wall, and the inner peripheral wall 3 is hung from the lower surface of the top wall to the inner surface of the mouth / neck portion. A nozzle 4 having a quadrangular cross section is erected from the center of the top wall. As clearly shown in FIG. 3, elastic side plates 5, 5 are erected in a taper shape from both left and right sides of the upper end surface of the nozzle so as to spread upward and outward. These side plates project forward long, and the bottom plate 6 also projects long from the front end of the nozzle upper end to form a forward extension of the nozzle upper surface. An elastic top plate 7 is installed between the upper ends of the both side plates in a generally arch shape.

First and second refraction lines 8 and 9 are provided at the lower end of the both side plates and the joint between the both side plates and the top plate. As shown in FIGS. 2 and 4, by pressing down the top plate 7, the upper and lower ends of both side plates 5 and 5 open outward and descend, so that the lower surface of the top plate 7 is above the nozzle. The end opening surface can be closed. When pushing down the top plate, both side plates 5 and 5 try to rotate with the first refraction lines 8 and 8 as fulcrums, but since the upper ends are connected to the left and right ends of the top plate through the second refraction lines 9. , It bends downwards against its elasticity and descends, and after a point of thought, its elastic restoring force causes it to reverse its elasticity and press the lower surface of the top plate 7 against the upper end opening surface of the nozzle as shown in Figs. Then, the opening is closed. When the top plate 7 is pulled up, both side plates are elastically inverted and the top plate 7 is pushed up above the nozzle. The rear wall 10 having elasticity is projected rearward from the rear edge of the upper end of the nozzle through a refraction line, and the upper end of the rear wall 10 is inclined obliquely backward and is connected to the rear end of the top plate which is inclined and projected through a refraction line. The rear surface is closed in this manner, but the rear wall may be omitted.

In the embodiment shown in FIGS. 1 to 4, when the central portion of the top plate 7 is pushed down from the nozzle hole 4a opening state shown in FIGS. 1 and 3, the side plates 5 and 5 resist the elasticity. After being pushed down with the first bending line 8, 8 as a fulcrum, it bends and bends, and then elastically restores, and the upper ends of both side plates 5, 5 descend downward outward as shown in Figs. At this time, the lower surface of the central portion of the top plate closes the upper end of the nozzle hole 4a. By pulling up the top plate from the closed state, contrary to the case of the above-mentioned pushing down, after the both side plates pass the thought point, they are elastically reversed and both side plates 5 and 5 move upward and outward as shown in FIGS. 1 and 3. Stand up and keep the nozzle holes open.

The second embodiment shown in FIGS. 5 and 6 is one in which the front and rear diameter portions of the cap top wall 1 are raised to form a nozzle as a whole, and a nozzle hole 4a is opened in the center of the upper wall thereof. An example in which the left and right side plates 5, 5 and the top plate 7 are formed long in the front-rear direction is shown.

In contrast to the second embodiment, the third embodiment shown in FIGS. 7 and 8 has an inverted trapezoidal recess formed in the front and rear diametrical directions of the top wall of the cap. A nozzle hole 4a is bored in the center, and the left and right side plates of the recess are side plates 5, 5, and a top plate 7 is installed between the upper ends of both side plates. In the case of this embodiment, the joint between the side plate and the top plate is the first refraction line 8, and the second refraction line 9 is provided in the front-rear direction between the left and right portions of the central portion of the top plate in the left-right direction. . In the case of this embodiment, the plate portions as the left and right portions of the top plate 7 are elastically inverted, and as shown in FIG. 8, the top plate 7 fits into the recess of the cap top wall when the nozzle holes are closed. Will be done.

In the fourth embodiment shown in FIGS. 9 and 10, the lateral width of the side plates 5, 5 is made equal to the lateral width of the upper end of the nozzle, and the lower end of the side plate is the same as in the first and second embodiments. And the first and second refraction lines 8 and 9 are provided at the joint between the side plate and the top plate 7. In the embodiment, the side plates 5, 5 as plate portions for elastic reversal are provided so as to bend upward and outward when the side plates are erected, and by doing so, the elastic reversal is facilitated. The upper end surface of the nozzle is also curved in the same manner as the lower surface of the top plate 7 so as to make surface contact when the top plate descends.

[0012]

[Effect of device]

 Since the present invention has the already described configuration, the nozzle hole can be easily opened and closed, and the plate portion between the first refraction line 8 and the second refraction line 9 is elastically inverted to open and close the nozzle hole. Therefore, for example, there is no possibility that the nozzle hole will be opened carelessly or that the top plate will be lowered during the opening of the nozzle hole to prevent the pouring of the contents stored in the container.

[Technical field to which the device belongs]

 The present invention relates to a cap for pouring a fluid such as liquid or powder.

[0002]

[Prior art]

 As a cap of the above type filed by the present applicant, for example, there is a device disclosed in Japanese Utility Model Laid-Open No. 62-159352. The cap is formed by forming a recess having a reverse trapezoidal vertical cross-section with the upper surface and the front end surface open, and from the upper part of the recess to the upper part of the front surface of the peripheral wall from the rear part of the top surface of the cap to the upper part of the front surface of the peripheral wall. Contrary to the recess, it is a trapezoidal long lid with the bottom side removed, and the lower edges of the left and right side plates of the long lid and the left and right upper edges of the recess are used. The left and right side edges of the plate are covered by connecting them via thin hinges respectively, and the bottom plate of the recess is provided with an outflow hole to form a nozzle with the recess and the long lid. When the upper lid plate is pushed down, the left and right side plates of the long lid are elastically reversed, and the lower surface of the upper plate of the long lid seals the outflow hole, and when the upper plate of the long lid is pulled up, the left and right side plates are elastically reversed again. It is provided so that the nozzle hole can be opened.

[0003]

[Problems to be solved by the device]

 The above-mentioned cap elastically deforms the left and right side plates of the long lid, and since the left and right side plates are triangular with the upper and lower side edges being longer than the front edge, the upper and lower plates of the long lid can be pushed down and pulled up. In this case, the elastic deformation for elastic reversal is mainly performed at the front part of the side plate, so that the elastically deformed portion is likely to be small, and there is a drawback that it becomes difficult to cause the elastic reversal when the cap is downsized. Further, since the nozzle is opened at only one end, there is an inconvenience that it is necessary to re-hold the container body with the cap so that the opening is located in a direction in which the hand can be easily tilted when the stored item is discharged.

The present invention eliminates the above drawbacks by making the cross-sectional shape of the nozzle the same in the front and rear, opening both front and rear ends of the nozzle, and further reducing the width in the front and rear direction.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention hangs a peripheral wall 1 for fitting a container mouth neck portion from an outer periphery of a top wall 2, and bulges a central portion of the top wall into a cylindrical shape with an upper surface closed, and the ridge 3 The upper surface plate 4 is provided with an outflow hole 5 at the center thereof, and the upper surface plate is formed in a quadrangular shape and the upper surface of the quadrangular upper surface plate is formed into an arcuate surface having an intermediate portion higher than the left and right side portions. The elastic side plates 7, 7 of substantially the same width are projected obliquely outward from the left and right side edges of the left and right side through the first thin hinges 6, 6, and are formed in a substantially arch-shaped cross section to the upper end edges of both elastic side plates. The left and right lower end edges of the elastic top plate 8 formed are connected via the second thin hinges 9 and 9, and the elastic side plates 7 and 7 are displaced so as to project downward from the first thin hinges 6 and 6. By doing so, the outflow hole 5 is formed so that the lower surface of the elastic top plate 8 can be sealed.

[0006]

[Embodiment of device]

 In the fluid pouring cap of the present invention, the peripheral wall 1 for screwing the neck of the container body is suspended from the outer periphery of the top wall 2. A ridge 3 is erected from the central portion of the top wall 2, and an upper surface plate 4 of the ridge 3 has a quadrangular shape, an outflow hole 5 is formed at the center of the upper surface plate, and the upper surface of the upper surface plate is formed from the left and right portions. Also has an arcuate surface with a high middle portion. From the left and right side edges of the top plate, the elastic side plates 7 and 7 are protruded by bending obliquely outward through the first thin hinges 6 and 6, and to the upper edges of both elastic side plates, the cross section has a voluminous arch shape. The left and right lower end edges of the formed elastic top plate 8 are connected via second thin hinges 9, 9.

The upper plate 4, the elastic side plates 7, 7 and the elastic top plate 8 of the raised portion form a nozzle 10 having front and rear end surface openings. As shown in FIG. 2, when the elastic top plate 8 is pushed down, the nozzle is displaceable so that the elastic side plates 7 and 7 are elastically inverted about the first thin hinges 6 and 6 and protrude outward downward. In this state, the lower surface of the elastic top plate 8 is provided so as to seal the outflow hole 5. As shown in FIG. 2, the elastic top plate 8 is provided so that the outer edge portions 8a, 8a at the lower ends of the left and right side portions thereof project outward from the second thin hinges 9, 9 when the outflow hole 5 is sealed. By doing so, it is possible to hook the fingers on the outer edge portions 8a, 8a and pull up the elastic top plate 8 to open the outflow hole 5 as shown in FIG. However, it is not always necessary to form in this way, and for example, the front and rear ends of the upper plate portion of the elastic top plate may be lifted by fingers, and further, finger recesses may be provided on the outer surfaces of both the right and left sides of the elastic top plate 8. The elastic top plate 8 may be pulled up by use. The cap can be integrally molded with a synthetic resin agent.

In the fluid pouring cap, the outflow hole 5 is opened in the state shown in FIG. 1, and when the elastic top plate 8 is forcibly pushed down from that state, the elastic side plates 7, 7 are released. It elastically revolves and pivots around the first thin hinges 6 and 6 to be displaced downward and outward, and at this time, the lower surface of the elastic top plate 8 closes the outflow hole 5. By pulling up the elastic top plate 8 from this state, the elastic side plates 7 and 7 are elastically reversed again around the first thin hinges 6 and 6 to return to the outlet hole opening state of FIG.

[0009]

[Effect of device]

 The present invention is configured as described above, and the elastic side plates 7 and 7 are protruded obliquely outward from the left and right side edges of the upper surface plate 4 of the raised portion rising from the top wall 2 via the first thin hinges 6 and 6. The upper and lower edges of the elastic side plates are connected to the left and right lower side edges of the elastic top plate 8 having a substantially arcuate cross section through the second thin hinges 9, 9, that is, the upper plate 4 and the elastic side plates. Since the nozzle 10 is formed by 7 and 7 and the elastic top plate 8, the nozzle is opened at both front and rear ends. Unlike the nozzle of the above-mentioned conventional example in which only one end is opened, both nozzles are opened. The stored fluid can be poured out, and thus the inconvenience of having to re-hold the container in order to change the direction of the nozzle opening of the capped container can be eliminated. Further, since the nozzle is open at both ends and has elastic side plates 7 and 7 of substantially the same width from the front end to the rear end of the nozzle, the elastic side plates are similarly elastically deformed at any position between the front and rear, and therefore the existing The elastic inversion does not become difficult unlike the conventional example. Further, since the central portion of the top wall is raised in a cylindrical shape to form a horizontal nozzle on the raised portion, the upper surface plate of the raised portion is formed in a quadrangular shape, and the first thin hinges 6 and 6 are provided from the left and right side edges thereof. Since the elastic side plates 7 and 7 are erected upward and outward through the interposition, the cap shape can be made unique, and the width of the elastic side plate in the front-rear direction can be reduced, so that the elastic inversion of the elastic side plate is further improved. It will be easy.
