Description

  The present invention relates to a hinge cap that is attached to the mouth of a container filled with highly viscous contents and can easily open and close the upper lid. More specifically, after the container contents are opened and poured out. In particular, in the case of highly viscous contents, it is possible to scrape the contents adhering to the inner wall surface of the dispensing cylinder during dispensing so that the dispensing space of the dispensing cylinder is not blocked at all times. It relates to a hinge cap.

  In the hinge cap, the cap body and the upper lid are connected by a hinge, and in addition to the openability of the upper lid, easy opening of the cap body is also given, and the convenience is enhanced, so seasoning and natural fruit juice It is often used for containers that contain liquid contents such as. In other words, the hinge cap is liquid-tight by screwing or plugging the cap body into the mouth of the container, and maintains the liquid-tight state so as not to be easily removed. In addition, there is a type in which the upper lid can be freely opened and closed by the hinge connection, and the hinge cap can be screwed and detached from the container mouth portion with the hinge connected.

  Containers with hinged caps often contain liquid contents that are frequently used such as seasonings because of the openability of the top lid, and a lid is provided on the top lid to make it easier to open and close. Furthermore, after the cap body is covered with the upper lid, the upper lid is not detached from the cap body except during use. However, when a hinge cap is used for a container containing a liquid material having a high viscosity, for example, a liquid miso that has recently been on the market for the convenience of cooking, When liquid miso adheres to the inner surface of the dispensing tube and it becomes dry and solidified, the dispensing space of the dispensing tube will be reduced, which is not only unsanitary but also good in appearance. It's not a thing and it's wasted.

  Therefore, the amount of liquid miso dispensed should be removed if the liquid miso remaining on the inner surface of the dispensing tube is removed from the inner surface of the dispensing tube each time the dispensing is completed. Will not decrease and will not be wasted. From this point of view, after opening the upper lid from the cap body of the hinge cap and pouring out an appropriate amount of liquid miso from the dispensing tube, when closing the upper lid, scrape off the remaining liquid miso attached to the inner surface of the dispensing tube Can be considered.

  As shown in FIG. 7, as shown in FIG. 7, the cap body 50 and the upper lid 51 are connected to each other by a hinge 52 so that the liquid miso can be scraped off when the upper lid is closed. The upper lid 51 is provided with an inner plug 53, and the tip 53 a of the inner plug 53 extends outwardly downward, and when the upper lid 51 is put on the mouth 55 of the container 54, There is one in which the distal end portion 53a of the inner plug 53 is in close contact with the inner peripheral surface (see, for example, Patent Document 1).

  Similarly, when the upper lid is closed, the hinge cap that can scrape off the miso is connected to the cap body 50 and the upper lid 51 so as to be opened and closed by the hinge 52 as shown in FIGS. The cap cylinder 50 is provided with a pouring cylinder 56 standing upright, and the upper lid 51 is formed with an inner ring 57 that contacts and seals the inner peripheral surface of the pouring cylinder 56. When covered, there is a case in which the bulging ring 58 at the tip of the inner ring 57 is in sliding contact with the inner peripheral surface of the dispensing cylinder 56 (see, for example, Patent Document 2).

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

In the drawings, reference numeral 1 denotes a hinge cap. The hinge cap 1 is formed by connecting a cap body 10 and an upper lid 20 so as to be freely opened and closed by a hinge 30.
The cap body 10 is composed of a top surface 11 and a skirt wall 12 that hangs down from the periphery of the top surface 11 and is attached to the mouth 3 of the container 2, and forms a pouring cylinder 13 on the top surface 11. In addition, a planned opening portion 16 surrounded by an annular fragile line 15 is formed on the closing middle plate 14 provided in the pouring cylinder 13, and on the upper surface inside the planned opening portion 16 in the vicinity of the planned opening portion 16. A pull ring 18 is erected via a support column 17 to form an outer wall 19 for closing and fixing the upper cover 20 outside the pouring cylinder 13 on the top surface 11. The upper cover 20 includes a top plate 21 and the top plate. The inner ring 23 is formed by a side wall 22 that hangs down from the peripheral edge of the base plate 21, hangs down from the inner surface of the top plate 21, contacts the inner peripheral surface of the extraction tube 13, and is opposite to the hinge 30. Ridge 24 protruding outward from the outer surface of the side wall 22 It is intended to be provided.

  By providing a scraping portion 25 that is thin and extends outward at the tip of the inner ring 23 of the upper lid 20, and the outer surface of the scraping portion 25 is in close contact with the inner peripheral surface of the dispensing cylinder 13. The inside of the container 2 after the breakage of the fragile line 15 can be maintained, the planned opening 16 is cut off by the pull ring 18, and the contents 4 in the container 2 are removed from the dispensing cylinder 13. After the dispensing, when the cap body 10 is covered with the upper lid 20, the scraping portion 25 at the tip of the inner ring 23 can scrape off the remaining contents 4 of the container 2 attached to the inner surface of the dispensing cylinder 13. Is.

Further , when the top lid 20 is put on the cap body 10, there is a range where the scraping portion 25 at the tip of the inner ring 23 is not in sliding contact with the inner side surface of the upper portion of the dispensing cylinder 13, and the content 4 remaining in this range is sufficiently There is a drowning that will not be scraped off. In order to avoid this problem, in the present invention, the inner side surface of the dispensing tube 13 is formed vertically.
By making the inner surface of the dispensing cylinder 13 vertical, the possibility that the remaining contents 4 adhered to the inner surface of the dispensing cylinder 13 will flow down by its own weight increases, and the inner ring 23 is covered when the top cover 20 is covered. The starting height of the sliding contact with the tip can be made from the upper end side of the pouring cylinder 13, and coupled with the effect that the contents 4 flow down under its own weight, the contents are placed on the inner peripheral surface of the upper part of the pouring cylinder. It is possible to effectively avoid remaining.

  The container 2 that bears the hinge cap 1 is not particularly limited as long as the cap body 10 can be attached to the mouth portion 3 by plugging or screwing, and any type and material may be used. In the container 2 of the first embodiment, the inner cylinder 5 is provided concentrically with the skirt wall 12 on the lower surface of the top surface 11 of the cap body 10, and the mounting formed between the skirt wall 12 and the inner cylinder 5 is provided. The container 6 is crowned with the hinge cap 1 by placing the part 6 in the mouth 3 of the container 2 and plugging it. The hinge cap 1 is used for frequently dispensing high-viscosity contents such as liquid miso, and is relatively opened and closed by the upper lid 20, and on the inner surface of the dispensing cylinder 13 of the cap body 10. It is assumed to be used when it is likely to adhere and remain.

  As described above, the cap body 10 is formed by plugging the mounting portion 6 formed by providing the inner cylinder 5 concentrically with the skirt wall 12 on the lower surface of the top surface 11 to the mouth portion 3 of the container 2. Become liquid-tight. Furthermore, since the upper lid 20 is connected to the cap body 10 via the hinge 30 as described above, the upper lid 20 can be rotated around the hinge 30. And since the said outer side wall 19 is provided on the top | upper surface 11 outside the said extraction pipe | tube 13, as above-mentioned, even if there is a liquid dripping from the extraction | pouring cylinder 13, from the outer wall 19 immediately. It is designed not to spill outside.

  The weak line 15 in the cap body 10 has a score 15a formed from the upper side, and is provided at the boundary between the dispensing tube 13 and the closing middle plate 14, so that the opening planned portion is formed by the pull ring 18. 16 is cut along the score 15a of the fragile line 15 and opened, the closed plate 14 is not left in the pouring cylinder 13, and the contents 4 scraped off by the scraping portion 25 are smooth as it is. It can be returned to the container 2.

  Further, the closing middle plate 14 provided in the dispensing cylinder 13 of the cap body 10 is inclined downward toward the hinge 30 side, makes it easy to cut the planned opening portion 16 by the pull ring 18, and the inner ring 23. A guide portion 26 described later is easily stored. Therefore, since the closing middle plate 14 is inclined downward toward the hinge 30 side, the fragile line 15 attached to the closing intermediate plate 14 is also inclined downward, and the score 15a of the fragile line 15 is easily broken, and the opening scheduled portion 16 is easily cut out, and a space is created in the extraction tube 13 on the hinge 30 side, so that the guide portion 26 of the inner ring 23 can be accommodated.

  As described above, the upper lid 20 has the side wall 22 and the inner ring 23 suspended from the outer side to the inner side under the top plate 21, and one end of the side wall 22 is connected to the hinge by a hinge 30 so that it can be opened and closed. A flange 24 is provided at the other end to facilitate opening and closing of the upper lid 20. Further, a ring-shaped groove 22a is provided on the inner peripheral surface of the side wall 22, and in cooperation with the outer wall 19 of the cap body 10, it prevents the upper lid 20 from coming off after opening and prevents entry of dust and the like.

  Further, a guide part 26 for the contents 4 is provided under the scraping part 25 on the hinge 30 side of the inner ring 23 of the upper lid 20, and the hinge 30 side of the dispensing cylinder 13 of the cap body 10 is provided from the guide part 26. A content receiver 27 for receiving the content 4 is provided. Accordingly, when the contents 4 in the container 2 are opened and opened, and then the upper lid 20 is opened and closed again from the cap body 10 to use the contents 4 in the container 2, the contents remaining in the inner ring 23 of the upper lid 20 are retained. 4, the guide portion 26 of the inner ring 23 and the content receiving portion 27 in the dispensing cylinder 13 of the cap body 10 do not come out of the inner ring 23 and the dispensing cylinder 13.

Next, a method for using the hinge cap 1 configured as described above will be described.
First, the upper lid 20 is fitted to the cap body 10 to form the closed hinge cap 1 shown in FIG. 1, and the container 2 is filled with contents 4 such as liquid miso, and then the hinge cap is placed on the mouth 3 of the container 2. 1 is attached, that is, the cap 3 is applied to the mouth 3 of the container 2 and the inside of the container 2 is sealed (see FIG. 2). Then, if necessary, the container 2 with the hinge cap 1 is packaged to obtain a final product.

  In use, the upper lid 20 can be opened by placing the finger on the collar 24 of the upper lid 20 and pushing up the upper lid 20, and the inner ring 23 of the upper lid 20 is removed from the dispensing cylinder 13 of the cap body 10. Then, the planned opening portion 16 is cut along the score 15 a of the weak line 15 by the pull ring 18 and opened.

  Then, a necessary amount of the content 4 such as liquid miso in the container 2 can be poured out from the dispensing tube 13 to another container or the like. After the content 4 has been poured out, the cap body 10 is covered with the upper lid 20, but the scraping portion 25 at the tip of the inner ring 23 is thin, so that it is easy to bend and the The contents 4 remaining on the inner surface can be scraped off by the scraping portion 25 at the tip of the inner ring 23. On the other hand, the scraped contents 4 are smoothly returned to the container 2 because the closing middle plate 14 in the dispensing cylinder 13 is completely removed. After the scraping, the scraping portion 25 seals the dispensing tube 13 and seals the contents 4 in the container 2 so as not to leak. Thereafter, the same operation described above is repeated until the content 4 in the container 2 is used up (see FIG. 5).

  In the process until the contents 4 in the container 2 are used up, the contents 4 are placed in the inner ring 23 of the upper lid 20 by shaking or lying down to prevent the contents 4 from being settled. This causes a phenomenon in which adhesion remains. Then, when the upper lid 20 is opened from the cap body 10, the content 4 adhered and remaining in the inner ring 23 hangs down to the extraction cylinder 13 on the hinge 30 side due to the external force, but the guide at the tip of the scraping portion 25. The contents 4 are guided by the part 26, and the contents 4 hang down on the contents receiving part 27, and when the top cover 20 is put on the cap body 10, the contents 4 hang on the contents receiving part 27 by the cooperation of the scraping part 25 and the guide part 26. The dropped contents 4 are scraped off and returned to the container 2 (see FIG. 6). Accordingly, the contents 4 do not contaminate the outside of the dispensing cylinder 13 and the inner ring 23.

  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.

  After the hinge cap of the present invention is opened and the contents of the container are used, each time the top cover is put on the cap body, the contents of the container remaining on the side surface of the dispensing cylinder are scraped off, and the viscosity of the contents is reduced. Even if it is high, the availability is extremely high when it is desired not to block the dispensing tube and to secure the sealing.
