Description

  The present invention relates to a two-piece hinge cap formed by separately forming a cap body and a hinge lid that covers the cap body, and fitting and connecting the hinge lid to the cap body.

  A hinge cap in which an upper lid (hinge lid) is hinge-connected to a cap body mounted on a container mouth is used for various purposes as a cap of a container filled with various seasonings, for example. Such a hinge cap is opened by turning the hinge lid. However, since the hinge lid is fixed to the cap body by a hinge band, the hinge lid is connected to the cap body even in the opened state. . Therefore, the hinge lid may become an obstacle when taking out the contents of the container from the container. For example, when a hinge cap is used as a cap of a container filled with a beverage, if a beverage is directly drunk while the hinge lid is opened, there arises a disadvantage that the nose hits the hinge lid.

There has also been proposed a hinge cap that is devised so that the opened hinge lid does not interfere with the removal of the contents of the container. For example, Patent Document 1 is fitted to the outer surface of the cylindrical side wall of the cap body on the hinge connecting portion side. A hinge cap is disclosed in which a fitting convex portion is provided and a fitting concave portion is formed on the hinge connecting portion side on the top surface of the top plate of the hinge lid. That is, in this cap, when opening the hinge lid, the hinge lid is swung largely until the top plate of the hinge lid hits the outer surface of the cylindrical side wall of the cap body, and the fitting convex portion is fitted into the fitting concave portion. Thus, the opened hinge lid is fixed so as not to obstruct the removal of the contents.

  However, in the hinge cap of Patent Document 1, not only is it necessary to accurately shape the position and size of the fitting convex portion and the fitting concave portion, but a general consumer can easily fit or fit the fitting cap. There is a problem of having to cancel. In other words, it is necessary to fix the hinge lid by fitting the fitting convex portion into the fitting concave portion, but if the fitting is not easy, the fitting is easily released and the hinge lid is hung and gets in the way. However, if the fitting is firmly performed so that the fitting is not easily released, it is difficult to close the hinge lid again, and it is extremely difficult to set the degree of fitting.

  Therefore, the object of the present invention is to easily hold the opened hinge lid so as not to obstruct the removal of the contents of the container by an extremely simple operation at the time of opening. An object of the present invention is to provide a hinge cap that can be closed again by operation.

According to the present invention, a cap body having a top plate portion and a cylindrical side wall that descends from the periphery of the top plate portion, and a cap body in which a container mouth portion is fitted and fixed inside the tubular side wall, is connected to the cap body. In a two-piece hinge cap consisting of a hinge lid,
A bearing frame for attaching a hinge lid is provided on the outer surface of the cylindrical side wall on the cap body, a concave portion for bearing is formed on the upper part of the bearing frame, and the outer surface of the bearing frame and the cylindrical side wall is formed. A space for holding the shaft that is open at least at the upper end is formed between
The hinge lid includes a lid formed from a top plate, a skirt wall descending from a peripheral edge of the top plate, an overhang portion projecting outward from the outer surface of the skirt wall, and a hinge band on the overhang portion. It consists of a fitting part that is hinged,
The fitting portion extends from a surface of the support substrate to which the hinge band is coupled and the side of the support substrate opposite to the hinge band, and is fitted into the fitting recess and is rotatably held. A shaft and a locking piece which is formed at the tip of the fitting shaft and is located in the shaft holding space and prevents the fitting shaft from being pulled out from the fitting recess,
When opening the cap, the lid of the hinge lid that closes the cap body is swung around the hinge band as a fulcrum, and then the hinge lid is rotated around the fitting shaft to invert the hinge lid. A two-piece hinge cap is provided that is capable of being held together.

In the present invention,
(1) The fitting shaft has a rectangular vertical cross section, and the bearing recess has a square shape corresponding to the vertical cross sectional shape of the fitting shaft.
Is preferred.

  In the two-piece hinge cap of the present invention, the hinge lid and the cap body are formed as separate bodies, and the fitting shaft provided on the hinge lid is fitted into the fitting recess of the cap body. The hinge lid is connected to the cap body. Therefore, when opening a plug, a general consumer turns the hinge lid with the hinge band as a fulcrum, opens the hinge lid, and then rotates the hinge lid with the fitting shaft as a fulcrum. The hinge lid can be inverted and held in a position that does not interfere with the removal of the container contents. Further, when closing the hinge lid again, the hinge lid is rotated with the fitting shaft as a fulcrum, reversed to the original state, and in this state, the lid is turned again in the closing direction with the hinge band as a fulcrum. Close it. Thus, in the present invention, the hinge cover that has been opened can be easily held so as not to obstruct the removal of the container contents by an extremely simple operation of rotation with the fitting shaft as a fulcrum, A similar very simple operation makes it possible to close again.

  In the present invention, the vertical cross-sectional shape of the fitting shaft is preferably a square shape (for example, a quadrangle), and the shape of the concave portion for bearing is also a rectangular shape (for example, a quadrangle) corresponding to the vertical cross-sectional shape of the fitting shaft. . Thereby, the fitting shaft can be rotated stepwise according to the angle of the side of the square, and in particular, the inverted state of the hinge lid can be stably maintained.

  In addition, the two-piece hinge cap of the present invention opens the hinge lid particularly when the container contents are beverages, and the opened hinge lid obstructs drinking when drinking directly from the container. There is an advantage that does not become. Therefore, in order to use for such a use, the content liquid pouring opening forming score is formed in an endless shape on the top plate portion of the cap body, and the upper surface of the top plate portion surrounds the score. It is preferable that a pouring tube formed as described above and a score tearing tab ring connected to a support provided in the vicinity of the score are formed.

And a lid 3. That is, the cap body 1 and the hinge lid 3 are formed as separate bodies and integrated by fitting as will be described later.

  Referring to FIGS. 5 and 6 showing the assembled state and FIGS. 7 and 8 showing the disassembled state, the cap body 1 is roughly composed of the top plate portion 5 and the top plate. It is comprised from the cylindrical side wall 7 hanging from the peripheral part of the part 5. FIG.

  An inner ring 9 is formed on the inner surface of the top plate portion 5 so as to extend downward with a space from the cylindrical side wall 7. That is, the cap main body 1 is mounted on the container mouth portion 80 by fitting the container mouth portion 80 into the space between the inner ring 9 and the cylindrical side wall 7 (see FIG. 1). An engagement protrusion 10 is formed on the inner surface of the lower end of the cylindrical side wall 7, and the cap main body 1 is connected to the container mouth portion by engaging the engagement protrusion 10 with the outer surface of the container mouth portion 80. It is firmly fixed to 80.

  Further, the top plate portion 5 is formed with a score 11 for forming a dispensing opening. On the top surface side of the top plate portion 5, a score breaking pull ring 13 is formed in the vicinity of the inside of the score 11. It is provided through the supporting column 15. That is, when the pull ring 13 is pulled, the score 11 is broken, and an opening for pouring out the contents is formed in the top plate portion 5.

  Furthermore, a pouring cylinder 17 for pouring liquid is formed on the upper surface side of the top plate portion 5 so as to surround the score 11, and the content liquid poured out through the pouring opening is It is guided by this dispensing cylinder 17. In the present invention, it is preferable that the pouring cylinder 17 is upright and straight so that the liquid in the container can be easily drunk (so that it is easy to drink so-called trumpet). A circumferential projection 19 for holding the closed hinge lid 3 is formed on the outside of the dispensing cylinder 17.

  In addition, a recess 21 is formed on a part of the outer surface of the cylindrical side wall 7 of the cap body 1 as shown in FIGS. 2 and 3, and this recess 21 is a closed hinge. The lid 3 is formed so that it can be easily opened with a finger.

  Further, referring to FIGS. 7 and 8 showing the disassembled state of the hinge cap, FIGS. 5 and 6 showing the assembled state, and FIG. 9 showing the side surface of the cap body 1, together with FIGS. A bearing frame 23 is integrally connected to the outer surface of the cylindrical side wall 7 of the cap body 1, particularly at a portion opposite to the concave portion 21. The bearing frame 23 is for attaching the hinge lid 3 to the cap body 1, and a bearing concave portion 25 is formed on the upper portion thereof (see FIGS. 7, 8 and 9 in particular). Both side end portions and lower end portions are connected to the outer surface of the cylindrical side wall 7. Between the bearing frame 23 and the outer surface of the cylindrical side wall 7, there is a shaft holding space 27 having an open upper end portion. Is formed. The attachment of the hinge lid 3 using the bearing frame 23 will be described later.

  On the other hand, referring to FIGS. 5 to 8 together with FIGS. 1 to 4, the hinge lid 3 roughly includes a fitting portion 3 a connected to the bearing frame 23 of the cap body 1, a lid portion 3 b, The overhanging portion 3c formed on the lid portion 3b, the overhanging portion 3c and the fitting portion 3a being hingedly connected by the hinge band 31, and the lid portion 3b and the overhanging portion 3c being fitted by the hinge band 31. It is possible to turn with respect to.

  First, the fitting portion 3 a will be described. The fitting portion 3 a has a support substrate 33, and a fitting shaft 35 is formed on one surface of the upper portion of the support substrate 33. That is, by fitting the fitting shaft 35 into the bearing recess 25 of the bearing frame 23 from above (see FIGS. 1 and 6), the fitting shaft 35 can rotate into the bearing recess 25. Thus, the hinge lid 3 is held on the cap body 1 so as to be rotatable about the fitting shaft 35.

  Further, a locking piece 37 having a larger diameter than the fitting shaft 35 is formed at the tip of the fitting shaft 35. That is, the locking piece 37 is accommodated in a shaft holding space 27 formed by the bearing frame 23 when the fitting shaft 35 is fitted into the bearing recess 25 from above (FIG. 1, FIG. 5 and FIG. 6 (9), the pull-out of the fitting shaft 35 from the bearing recess 25 is suppressed, and the connected state of the cap body 1 and the hinge lid 3 is stably maintained.

  On the other hand, referring to FIG. 1, lid portion 3 b has a top plate 51 and a skirt wall 53 extending from the periphery of top plate 51, and projects outwardly on the outer surface of the lower portion of skirt wall 53. An overhang portion 3c is formed. The projecting portion 3c and the support substrate 33 of the fitting portion 3a described above are connected to each other by a hinge band 31 so as to be rotatable. That is, by fitting the aforementioned fitting shaft 35 to the bearing recess 25 in a rotatable manner, the lid portion 3b of the hinge lid 3 connected to the cap body 1 is swung by the hinge band 31. Opening is performed.

  As shown in FIGS. 1 and 5 to 8, a seal ring 55 is formed on the inner surface of the top plate 51 in the lid portion 3 b, and when the hinge lid 3 is closed (see FIG. 1), The seal ring 55 is in close contact with the inner surface of the dispensing cylinder 17 of the cap body 1 so that the sealing performance is secured when the score 11 is broken to form the dispensing opening.

  Further, an engaging recess 57 is formed in a circumferential shape in the lower portion of the skirt wall 53, and when the hinge lid 3 is closed (see FIG. 1), the engaging recess 57 becomes the top plate portion 5 of the cap body 1. It is engaged with the circumferential projection 19 formed on the hinge lid 3 so that the closed state of the hinge lid 3 is stably maintained. Further, an opening tab 59 is formed on the outer surface of the lower end of the skirt wall 53 at a portion located on the side opposite to the overhang portion 3c. That is, when the hinge lid 3 is closed, the opening tab 59 is positioned just above the recess 21 formed on the cylindrical side wall 7 of the cap body 1. For this reason, a space is formed in the lower surface of the opening tab 59 by the concave portion 21, and the opening operation by pushing up the lower surface of the opening tab 59 with a finger can be easily performed.

  6 and 8, the hinge lid 3 is shown in an opened state, so that the engaging recess 57 and the opening tab 59 are shown in the upper part or the upper end part of the skirt wall 53. . Therefore, some members of the hinge lid 3 are upside down in FIGS. 1, 6, and 8.

  Referring to FIG. 8 in particular, the overhang portion 3c is formed on the outer surface of the lower portion of the skirt wall 53. The overhang portion 3c includes an overhang wall 61 projecting outward from the skirt wall 53 and the overhang wall. 61 has an upright wall 63 extending to the same height as the lower end surface of the skirt wall 53, and the upright wall 63 and the support substrate 33 of the fitting portion 3 a described above can be turned by the hinge band 31. It is connected to.

  Referring to FIGS. 5 and 7 together with FIG. 1, the hinge band 31 is a wide band that connects the lower end (upper end in FIGS. 6 and 8) of the upright wall 63 to the upper end central portion of the support substrate 33. 31a, a portion provided on both sides of the wide band 31a, and a portion slightly above the lower end of the upright wall 63 (below in FIGS. 6 and 8) and a portion slightly below the upper end of the support substrate 33 Narrow bands 31b and 31b are connected to each other. Moreover, it is preferable to insert a recess 65 in the central portion of the wide band 31a so that the band can be bent easily. Such a hinge band 31 closes and opens the hinge lid 3 (the lid portion 3b and the overhang portion 3c). In particular, the narrow band 31b, 31b, which is different from the wide band 31a, opens the plug. When done, the opening proceeds to a certain angle at once, and the hinge lid 3 is stably held at that angle. This is because the tension by the narrow band 31b acts.

  Further, when the hinge lid 3 (the lid portion 3b and the overhang portion 3c) is turned from the assembled state shown in FIG. 6 to the closed state shown in FIG. 1, the lid portion 3b is just the top plate portion 5 of the cap body 1. At the same time that the upper surface of the bearing frame 23 is closed, the overhang portion 3 c covers the upper surface of the bearing frame 23.

  In the present invention, when the hinge lid 3 is opened, the hinge lid 3 can be reversed by rotating it around the fitting shaft 35, so that the opened hinge lid 3 is obstructed. In this case, the liquid in the container can be poured out.

  That is, referring to FIG. 11 for explaining this function, the hinge lid 3 is closed in the hinge cap attached to the mouth 80 of the container 85 as shown in FIG. When the hinge lid 3 is opened in this state, as shown in FIG. 11B, the hinge lid 3 (the lid portion 3b and the overhang portion 3c) is opened at a stretch to a certain angle, and is stably held at that angle. The In this state, a pulling opening is formed by tearing the score 11 by pulling the tab ring 13, and the liquid in the container is poured out. In particular, when the liquid in the container is a beverage, as shown in FIG. For direct drinking in a state, the opened hinge lid 3 becomes an obstacle. At this time, in the present invention, the hinge lid 3 can be rotated and inverted about the fitting shaft 35, whereby the hinge lid 3 is inverted as shown in FIG. 11 (c). In this state, the container hangs down to the container 85 side. That is, in the state of FIG. 11C, the hinge lid 3 does not get in the way, and it is possible to easily drink the beverage that is the container content liquid. In particular, since the hinge lid 3 is held in the state of FIG. 11A for a long period of time, the hinge band 31 is bent in a bent state, and therefore the container 85 is tilted and drunk. Even if it is not held down by hand, the state shown in FIG. 11C is stably maintained, and the hinge lid 3 does not interfere with drinking.

  In the present invention, the shape of the fitting shaft 35 and the bearing recess 25 is not particularly limited as long as the fitting shaft 35 can be rotatably fitted in the bearing recess 25. For example, FIG. As shown in the drawing, the vertical cross-sectional shape of the fitting shaft 35 is preferably a square shape (for example, a quadrangle). In this case, as shown in FIG. The shape of the recess 25 is also preferably a square shape (for example, a quadrangle) corresponding to the vertical cross-sectional shape of the fitting shaft 35. That is, by forming the fitting shaft 35 and the bearing recess 25 in such a shape, the fitting shaft 35 can be rotated stepwise in accordance with the angle of the square, and the reversing angle can be adjusted as appropriate. In particular, since the angle is stable, there is an advantage that the inverted state of the hinge lid 3 as shown in FIG. 11C can be held extremely stably.

  As described above, the two-piece hinge cap of the present invention is extremely useful as a cap for a beverage container because the hinge lid 3 opened at the time of drinking a direct beverage does not get in the way.
