It is a longitudinal cross-sectional view of the state which opened completely.
In these drawings, a hinge cap 1 is a cap body 10 and an upper lid 20 which are connected to each other by a hinge 30 so as to be freely opened and closed. The cap body 10 is suspended from the top surface 11 and the periphery of the top surface 11. The skirt wall 12 is fitted and fixed to the mouth portion 3 of the container 2, and the opening 11 is formed on the top surface 11 and the pouring cylinder 14 surrounding the opening 13 is formed. 14 is formed with an outer wall 15 for closing and fixing the upper lid 20, and the upper lid 20 is composed of a top plate 21 and a side wall 22 depending from the periphery of the top plate 21. An inner ring 23 that hangs down from this and contacts the inner surface of the dispensing cylinder 14 of the cap body 10 is formed. After the opening 13 is removed during use, the cap is again covered with the cap body. In, by the inner ring 23 abuts against the pouring cylinder 14, is to seal the container.

  The container 2 to which the hinge cap 1 is attached is not particularly limited as long as the cap body 10 can be stoppered or screwed into the mouth portion 3, and may be of any type and material. In the first embodiment, an example of a container in which opening and closing by the upper lid 20 is performed relatively frequently is shown, particularly for use in frequently dispensed items such as seasonings.

  The cap body 10 is provided with a skirt wall 12 and an inner cylinder 16 below the top surface 11 to form a fitting portion 17, and the mouth portion 3 of the container 2 is plugged into the fitting portion 17. Make it liquid-tight. Furthermore, as described above, since the upper lid 20 is connected to the cap body 10 via the hinge connecting portion 30, the upper lid 20 is rotatable around the hinge connecting portion 30. Since the outer wall 15 is provided on the top surface 11 outside the pouring tube 14 as described above, even if there is liquid dripping from the pouring tube 14, the outer wall 15 is immediately outside. No spills.

  4 and 5, the upper end portion 14a on the hinge connecting portion side of the pouring tube 14 of the cap body 10 forms a flange portion 18 that is formed in a flange shape protruding outward in the radial direction, In addition, since the extended portion 24 is provided on the end of the inner ring 23 of the upper lid 20 on the hinge connecting portion 30 side, the liquid content attached to the inner ring 23 of the upper lid 20 does not leak to the outside. It has become.

  Further, when the upper lid holding convex portions 19 are provided on both sides of the hinge connecting portion 30 at the upper end of the skirt wall 12 of the cap body 10 and the upper lid 20 is opened about 90 degrees with respect to the cap body 10, the lower end of the side wall of the upper lid 20 is the upper lid. The upper lid 20 can be held in a state of being opened about 90 degrees with respect to the cap body 10 by stopping against the holding convex portion 19, and as described above, the extended portion 24 of the upper lid 20 is formed on the cap body 10. The liquid content 4 adhered to the inner ring 23 of the upper lid 20 smoothly flows down into the container 2 with the guarantee that it is located on the radially inner side of the flange 18, and the liquid content in the container 2 It is easy to transfer 4 to another container.

  The upper lid holding convex portion 19 has an inclined surface 19a whose upper surface is inclined radially outward and upward. Therefore, when the consumer opens the upper lid 20 with a finger or the like, the inclined surface 19a gradually As a result, the consumer can be aware of an appropriate opening degree of the upper lid 20, for example, about 90 degrees, and stop opening any more. Therefore, the upper lid holding convex portion 19 provided on the skirt wall 12 of the cap body 10 prevents the upper lid 20 from being opened at an appropriate angle, and the liquid content 4 adhering in the inner ring 23 of the upper lid 20 is extended. It can be guided by the outlet portion 24 and reliably flowed down into the container 2. In addition, it is possible to prevent the liquid contents 4 from being opened in the inner ring 23 and on the extension 24 even if the upper lid 20 is forcibly opened more than about 90 degrees. Will not spill outside.

  The planned opening portion 13 inside the dispensing tube 14 is surrounded by a score 13a and is a part that can be removed by breakage.When the score tearing tab 5 provided on the planned opening portion 13 is hooked and pulled, The score 13a can be broken to remove the planned opening portion 13 for opening. In FIG. 1, reference numeral 5 a denotes a slip stopper when placing a finger on the score tearing tab 5. On the other hand, the main seal after opening is performed by fitting the inner ring 23 of the upper lid 20 into the extraction tube 14 of the cap body 10. That is, when the outer peripheral surface of the inner ring 23 is in sliding contact with the inner peripheral surface of the dispensing tube 14, sealing after opening is performed.

  The upper lid 20 has a side wall 22 and an inner ring 23 that are suspended from the outer side to the inner side under the top plate 21. One end of the side wall 22 is connected by a hinge connecting part 30 so that it can be opened and closed. Is provided to facilitate the opening and closing of the upper lid 20. Further, a locking ridge 26 is formed on the inner peripheral surface of the side wall 22 and is locked to the locking ridge 15a of the outer wall 15 of the cap body 10 to prevent the upper lid 20 from coming off by cooperation thereof. Prevents intrusion of garbage.

Next, a method for using the hinge cap 1 configured as described above will be described.
First, the hinge cap 1 with the top lid 20 fitted to the cap body 10 is filled, the liquid content 4 is filled into the container 2, and the mouth 3 of the container 2 is plugged into the fitting portion 17 of the cap body 10. Thus, the inside of the container 2 is sealed with the hinge cap 1 (see FIG. 1). Then, if necessary, the container 2 with the hinge cap 1 is packaged to obtain a final product.

  When the final product is consumed, first, at least a portion of the hinge cap 1 is bare, and the upper lid 20 can be opened from the cap body 10. The upper lid 20 can be easily opened from the cap body 10 by pushing up the collar portion 25 with fingers. Further, when the score tearing tab 5 is pulled with a finger, the score 13a can be broken, and the opening scheduled portion 13 can be removed to open the score tear tab. Then, the required amount of the liquid content 4 in the container 2 can be poured into the necessary container or the like from the dispensing tube 14 of the cap body 10. When the cap body 10 is covered with the upper lid 20 after pouring the liquid content 4, the inner ring 23 is fitted into the dispensing cylinder 14, and the side wall 22 of the upper lid 20 and the outer wall 15 of the cap body 10 are And the liquid content 4 in the container 2 is sealed so as not to leak. Thereafter, the same operation as described above is repeated until the liquid contents in the container 2 are used up.

  However, when the liquid content 4 in the container 2 is used, if the container 2 is shaken with the top lid 20 covered to make the liquid content 4 homogeneous, the liquid content 4 will adhere to the inner ring 23 of the top lid 20. There are things to do. In this state, when the upper lid 20 is opened by pushing up the collar portion 25 with fingers, the load applied to the fingers gradually increases due to the inclined surface 19a of the upper lid holding convex portion 19, and an appropriate opening degree of the upper lid 10, for example, about 90 Be aware of the degree and stop opening any more. Therefore, the liquid content 4 adhering in the inner ring 23 is guided by the extending portion 24 and surely flows down into the container 2 via the flange portion 18 of the dispensing cylinder 14. In addition, when the upper lid 10 is forcibly opened more than about 90 degrees, the liquid content 4 stays in the inner ring 23 and on the extension part 24 and does not spill out.

  Furthermore, even if the liquid content 4 is poured out homogeneously while being rotated and shaken, or the liquid content 4 is poured out sideways, there is no notch or hole in the upper end portion 14a of the pouring cylinder 14. Since the liquid content 4 does not exceed the upper end portion 14a, the liquid content 4 does not leak to the outside and the surroundings are not soiled.

  While the first embodiment of the present invention has been described above, it should be understood that the specific configuration is not limited to this, and that modifications can be made as appropriate without departing from the scope of the present invention.

  Of course, the hinge cap of the present invention does not leak the liquid content attached to the upper lid to the outside, even if it is somewhat rough handling by the consumer, the liquid content in the container does not leak to the outside, When you do not want to pollute the surroundings, its availability is extremely high.
