As shown in FIG. 5, the tongue piece 40 has a mountain shape having a tip portion formed highest in a predetermined circumferential range when viewed from the direction of the hinge C (the direction of the arrow Y), and gradually increases from both sides of the tip portion. A slope portion 42 is formed to reduce the thickness.

A cut surface 43 having a chamfered outer peripheral surface is formed at the tip of the tongue piece 40 to form an acute point.
The outer peripheral surface 41 of the tongue piece 40 is provided with a friction locking portion 44 that rubs against the friction locking portion 28 provided on the inner peripheral surface of the lip portion 20 of the dispensing tube 5. As shown as a hatched range of 5, a predetermined width in the circumferential direction centered on the hinge C is provided from the vicinity of the cut surface 43 at the tip of the tongue piece 40 to the vicinity of the lower end 36 of the sealing cylinder 33.
Since the surface of the friction locking portion 44 has a rough surface such as a rough surface, embossed or knurled surface to increase frictional resistance, the inner peripheral surface of the lip portion 20 of the dispensing cylinder 5 and the tongue When the outer peripheral surface 41 of the piece 40 is in sliding contact, the upper lid B is locked at an arbitrary opening degree by rubbing the friction locking portion 28 and the friction locking portion 44.

In this embodiment, the opening degree at which the upper lid B can be locked is from 0 ° to about 80 °. However, the upper lid B is an angle that does not interfere with the dispensing of the content liquid, and the upper lid B can be tilted slightly. It is preferable that the content liquid adhering to the inner peripheral surface of the slag is such that it can easily recirculate through the tongue piece 40 to the spout, and the maximum opening is usually about 60 ° to 120 °. preferable.
Further, in the present embodiment, the tongue piece 40 is provided on the half circumference on the hinge C side, but it is not always required to be provided over the half circumference. 5 If it can be slidably contacted with the inner surface and the dripping of the adhering liquid can be prevented, it can be appropriately changed.
In the present embodiment, the friction locking portion for locking the upper lid B at an arbitrary opening during the opening of the lid, as shown in FIG. 2 (b), and the inner peripheral surface of the lip portion 20 of the dispensing cylinder 5 Although provided on both of the outer peripheral surfaces 41 of the tongue piece 40, the friction locking portion only needs to be provided on at least one of the inner peripheral surface of the dispensing tube 5 or the outer peripheral surface 41 of the tongue piece 40. Selectable.

Next, usage modes and operational effects of this embodiment will be described.
As shown in FIG. 3B, the hinge cap of the present embodiment is integrally formed with the cover fully opened.
In order to attach the hinge cap of this embodiment to the container body D, first, the upper lid B is rotated around the hinge C to close the lid, and the mouth portion 1 of the container body D is applied to the fitting groove 9 from above. By pressing and plugging, the overhanging protrusion 12 of the cap main body A gets over the engaging protrusion 2 of the container main body D, and the mouth portion 1 is fitted into the fitting groove 9.
In this embodiment, the fitting groove 9 is fitted into the mouth portion 1 and the hinge cap is mounted on the container body D. However, the present invention is not limited to such means, and other means such as screwing are used. You may wear it.

When closing the upper lid B, first, the cut surface 43 at the tip of the tongue piece 40 comes into contact with the tip 20a of the lip 20 of the dispensing tube 5 and rides on the inner peripheral surface of the lip 20; As shown in FIG. 1 and FIG. 2 (b), the friction locking portion 44 provided on the outer peripheral surface 41 of the tongue piece 40 is in sliding contact with the friction locking portion 28 provided on the inner peripheral surface of the lip portion 20. Then, the friction locking portion 28 rubs against the friction locking portion 44 and the upper lid B is locked.
When a force is further applied in the direction of closing the upper lid B from this state, the friction locking portion 28 and the friction locking portion 44 are merely rubbed together, so that the locking state is quickly released with a relatively small force, The tongue piece 40 has its upper lid B rotated while rubbing the inner peripheral surface of the lip portion 20, and the bulging portion 11 of the lid locking portion 10 is fitted in the locking groove 35 of the upper lid B, thereby completing the closing operation. Then, as shown in FIG. 2A, the lid is closed.

In order to use the container with the hinge cap attached, first, the finger 34 is pulled up and lifted from the state shown in FIG. 2A to release the fitting between the bulging portion 11 and the locking groove 35. Then, when the upper lid B is rotated, the outer peripheral surface 41 of the tongue piece 40 comes into sliding contact with the inner peripheral surface of the lip portion 20 of the dispensing cylinder 5 and the friction locking portion 28 rubs against the friction locking portion 44. Thus, the upper lid B can be opened to the position shown in FIG. 1, and the upper lid B can be locked at an arbitrary opening degree.
In this state, the pull ring 26 is pulled up, the thinned portion 23 is broken, the removal portion 24 of the partition wall 22 is cut off, and the spout is opened.
At that time, the pull ring 26 is provided with a flexible thin-walled finger rest 27, so that the finger does not hurt.

Since the upper lid B is locked at an arbitrary opening, if the container is tilted as it is, the content liquid in the container is guided and poured out from the spout to the inner peripheral surface of the lip portion 20 of the pour cylinder 5. The upper lid B does not rock and get in the way of being poured out or contaminated by the pouring liquid, and there is no trouble that the upper lid B has to be touched.
Furthermore, in the present embodiment, the frictional locking portion 44 of the tongue piece 40 is shown in the hatched range of FIG. 5 from the vicinity of the cut surface 43 at the front end portion of the tongue piece 40 to the vicinity of the lower end 36 of the sealing cylinder 33. However, since there is little need to lock the upper lid B with a small opening (for example, about 45 ° or less), the range in which the friction locking portion 44 is provided is limited to the vicinity of the cut surface 43 at the tip portion. May be. Then, when the lid is opened, the opening of the upper lid B can be smoothly opened when the outer peripheral surface 41 of the tongue piece 40 and the inner peripheral surface of the lip portion 20 of the dispensing cylinder 5 are less in frictional resistance. If the opening continues further, the friction locking portion 28 of the lip portion 20 of the dispensing cylinder 5 comes into sliding contact with the friction locking portion 44 provided on the tongue piece 40, and the frictional resistance suddenly increases. The user can be informed that the maximum opening is approaching.

In addition, when the container is tilted or shaken with the lid closed after use, the liquid content overflowing from the spout may adhere to the inner surface of the upper lid B. In order to use the container again, the upper lid B When the lid is opened, the content liquid adhering to the inner surface of the upper lid B flows down to the hinge C side, travels along the tongue piece 40 and returns to the spout, so that the adhering liquid does not drip and contaminate the surroundings.
In addition, although the hinge cap of the present embodiment has a flat top wall of the upper lid B, instead of this, if the inner surface of the top wall 31 on the inner peripheral side from the sealing cylinder 33 is formed in a dome shape, It is possible to prompt the content liquid adhering to the inner surface of the top wall 31 to quickly flow down to the inner periphery of the sealing cylinder 33.

Since the sharp tip is formed by the cut surface 43 in the front-end | tip part of the tongue piece 40, the liquid which transmitted the inner peripheral surface of the tongue piece 40 is easy to drip from this tip, and after closing a lid, The adhering liquid immediately flows down from the tip of the cut surface 43 at the tip of the tongue piece 40 which is the lowermost part, and the inside of the cap is kept clean.
Even when the opening degree of the upper lid B is relatively large and the adhering liquid accumulates as a residual liquid at the base of the tongue piece 40, the upper lid B may be tilted to use the container or may be closed again after use. When this is done, the residual liquid quickly returns to the spout through the tongue piece 40, so that the surroundings are not contaminated by the residual liquid.

Even if the residual liquid is relatively large and may return to the spout at a time, the overhanging portion 22a protrudes downward on the hinge C side of the partition wall 22 while being inclined downward. It is possible to prevent the residual liquid flowing down from the tip of the tongue piece 40 from directly falling into the container and scattering the content liquid, and to keep the container clean.
Further, since the tongue piece 40 forms an outer peripheral surface 41 having an arcuate cross section corresponding to the inner peripheral surface of the lip portion 20 of the dispensing cylinder 5, when the upper lid B is closed, the tip portion of the tongue piece 40 is the lip portion. The content liquid adhering to the inner peripheral surface of the lip portion 20 is scraped off to facilitate the flow of the content liquid adhering to the inner peripheral surface of the lip portion 20, while the top portion 20a of the lip portion 20 is a tongue piece when the upper lid B is opened. By scraping off the content liquid adhering to the outer peripheral surface 41 of 40, the flow of the content liquid adhering to the outer peripheral surface 41 of the tongue piece 40 can be promoted.

Further, the upper wall 6 is formed so that the width between the continuous portion with the pouring cylinder 5 and the continuous portion with the lid locking portion 10 is widened on the hinge C side. The gap b on the hinge C side between the lid locking portion 10 and the lid locking portion 10 has a wide space, and even if the content liquid falls on the upper wall 6 part carelessly, the dripping liquid is wiped off and the inside of the cap is removed. It can be kept clean.
Further, the hinge cap of the present embodiment, after finishing the use of the container, lifts the upper lid B to release the engagement between the frictional engagement portion 28 and the frictional engagement portion 44, and further raises the longitudinal tear line. Can be separated from the container body A and disposed of easily if the breakage is advanced to the horizontal tear line and the tightening of the overhanging projection 12 on the container body A is released.

  The hinge cap according to the present invention is capable of always locking the upper lid at an arbitrary opening and allowing the content liquid adhering to the inner surface of the upper lid to flow back to the spout through the tongue piece, so that the hinge cap is clean and easy to use. And can be suitably used as a cap for containers filled with food and drink, seasonings and the like that particularly require cleanliness.
