Japanese Utility Model Publication No. 2-21406 JP-A-11-255251

  However, providing an opening history indicating mechanism such as a TE band complicates the structure of the container lid, resulting in an increase in cost and the like. Also, the TE band is provided on the upper lid, and is always separated from the upper lid when the upper lid is opened. Due to the fact that the TE band is separated, the fact that the upper lid has been opened to the general consumer. It is to make you recognize. However, when the upper lid is attached to the cap body together with the separated TE band, the general consumer may overlook the fact that the TE band is separated, and its opening history clear function (TE property). Was not always satisfactory.

  Accordingly, an object of the present invention is to provide a container lid with a pull ring with improved TE properties without providing a special member such as a TE band.

According to the present invention consists of a cap body provided with a pull ring for forming and contents dispensing opening is fitted and fixed to the container mouth portion, an upper lid that is removably attached to the cap body pull ring Tsukeyo in Utsuwafuta, the top surface of the upper lid, the transparent regions are formed for observing a pull ring of the cap body, a portion of the top face all or top surface of the upper lid has a transparent region, the upper lid The other part is a translucent or opaque region, the upper lid is formed of a transparent material, and the translucent or opaque region of the upper lid is formed on a rough surface. A container lid is provided.

  In the container lid with pull ring of the present invention, a transparent region is formed at least on the top surface of the upper lid, and a general consumer can observe the pull ring of the cap body through the transparent region with the naked eye. Therefore, it is possible to recognize whether the pull ring is attached to or removed from the cap body with the top cover closed, and without opening a special member such as a TE band. Can be specified.

  In the present invention, the entire top surface of the top cover or a part of the top surface may be a transparent region, and the other part of the top cover may be translucent or opaque. That is, the entire upper lid can be made transparent, but when the entire cap body can be seen through the entire upper lid, the pull ring becomes rather inconspicuous. However, by making only the top surface of the upper lid transparent (that is, the entire top surface or a part of the top surface becomes the transparent region), the pull ring can be watched through the upper lid, and the pull ring is removed. This is because inconveniences such as oversight can be effectively avoided.

  In addition, when the internal solution adheres to the outside of the dispensing cylinder after use, it is preferable that the upper surface of the cap body is as inconspicuous as possible, so that only necessary portions are partially transparent than when the entire upper lid is transparent. Is preferred.

  The transparent region may be formed in an annular shape on the top surface of the upper lid, and the pull ring may be arranged so as to align with the annular transparent region when the upper lid is closed. That is, by configuring the pull ring so as to coincide with the annular transparent region, even a slight state change of the pull ring can be easily recognized, and the TE property can be further enhanced.

  Further, at least the upper lid may be formed of a transparent material, and at least the semi-transparent or opaque region of the upper lid may be formed on a rough surface. That is, it is preferable in terms of production and production cost to form a semi-transparent or opaque region by roughening a container lid made of a transparent material.

  Furthermore, in the present invention, it is preferable that the upper lid is colorless and the cap body is colored. This is because the cap body (particularly, the pull ring) can be seen most clearly through the transparent region.

The present invention will be described below based on specific examples shown in the accompanying drawings.
FIG. 1 is a top view (a), a side sectional view (b) and a bottom view (c) of a container lid with a pull ring of the present invention,
Drawing 2 is an explanatory view for explaining the function in other embodiments of the container lid with a pull ring of the present invention.

  Referring to FIGS. 1A to 1C, the container lid with a pull ring of the present invention includes a cap body 1 and an upper lid 2.

  The cap body 1 includes a top wall 5 and a cylindrical side wall 6 provided with an engagement protrusion 7 that engages with a mouth portion (not shown) of the container. It has a double wall structure composed of the outer side wall 19 and is connected at the lower end. The engaging protrusion 7 is formed on the lower inner surface of the inner wall. An upper wall 24 that protrudes inward from the upper end of the inner wall is formed, and an inner ring 9 that extends downward and a screw cylinder 16 that extends upward are provided inside the upper wall 24. A thread 17 for holding the upper lid 2 is formed on the outer surface portion of the spiral tube. An extraction tube 15 is provided at the upper end of the spiral tube via a connecting portion, and the top wall 5 is formed at the lower end portion of the extraction tube 15. That is, a container mouth portion is fitted into the space between the inner ring 9 and the cylindrical side wall 6, and the fitted container mouth portion is firmly fixed by the engagement protrusion 7.

  The top wall 5 is endlessly provided with a score 10, and an opening for pouring contents is formed in the top wall 5 by tearing the score 10. Therefore, a support column 11 is provided in the vicinity of the score 10, and a pull ring 13 is provided at the upper end of the support column 11. That is, by pulling the pull ring 13 with a finger and pulling it up, the score 10 is torn through the support column 11 and an opening for pouring the contents is formed.

  Further, the extraction cylinder 15 is provided so as to surround the score 10, and the pull ring 13 is accommodated in the extraction cylinder 15. That is, after pulling the pull ring 13 to form the pouring opening, the container contents can be smoothly poured out along the inner surface of the pouring cylinder 15 through the pouring opening. The upper end 15a of the pouring tube 15 extends in a trumpet shape to prevent dripping.

  The cylindrical side wall 6 constitutes the double wall structure by forming slits circumferentially by cutting from above. With such a configuration, by allowing the outer wall 19 of the cylindrical side wall 6 to be torn, the cap body 1 can be easily removed from the container mouth portion, and the sorting and discarding property is improved.

  On the other hand, the upper lid 2 includes a top surface 20 and a skirt portion 21.

  A ring-shaped small protrusion 22 is provided on the inner surface of the top surface 20. When the upper lid 2 is attached to the cap body 1, the small protrusion 22 comes into close contact with the inner surface of the dispensing tube 15. Yes. Thereby, the sealing performance after the opening for content extraction is formed by tearing the score 10 is secured.

  Further, on the inner surface of the skirt portion 21, a screw 23 that is screw-engaged with the screw 17 provided on the cap body 1 described above is formed. That is, the upper lid 2 can be attached to the cap body 1 by screwing these screws 17 and 23 together.

  An outer flange 25 is provided at the lower end of the skirt portion 21 as necessary. The outer flange 25 has the same outer diameter as the outer diameter of the upper end portion of the cylindrical side wall 6 of the cap body 1. When the upper lid 2 is closed, the upper end portion of the cylindrical side wall 6 (the inner side wall 18 and the outer side) The upper end of the wall 19 is covered exactly. Therefore, for example, when the cylindrical side wall 6 has a double wall structure by a cut (slit) from the upper end, such a cut (slit) can be concealed by the upper lid 2, and the product of this composite container lid Value can be increased.

  In the present invention, a transparent region for pull ring observation is formed on at least the top surface 20 of the upper lid 2. That is, by forming such a transparent region, the pull ring 13 can be visually observed with the upper lid closed. For example, the pull ring 13 is removed and an opening for content extraction is formed. If so, you can recognize that fact at a glance.

  The transparent region only needs to have transparency to the extent that the pull ring 13 can be seen from the outside, and is not necessarily completely transparent, and may be colored.

  In the present invention, the transparent region as described above can be formed on the top surface 20 as a result of making the entire upper lid 2 transparent, but only the top surface 20 is transparent and the skirt portion 21 of the upper lid 2 is formed. It is preferably opaque or translucent. That is, if the entire upper lid 2 is made transparent so that the entire inner cap main body 1 can be clearly seen, the pull ring 13 positioned inside the dispensing cylinder 15 will be inconspicuous and easily overlooked. turn into. Therefore, by making only the top surface 20 transparent, by limiting the clearly visible range to the pull ring 13 and its peripheral part, oversight and the like can be prevented. Alternatively, it is preferable that the upper surface of the cap body is as inconspicuous as possible when the internal solution adheres outside the dispensing cylinder after use.

  In addition, when the internal solution adheres to the outside of the dispensing cylinder after use, it is preferable that the upper surface of the cap body is as inconspicuous as possible, so that the clearly visible range is limited to the pull ring 13 and its peripheral portion. It is preferable that a circular transparent region 30 is formed on the top surface 20 and the other part is a translucent or opaque region 31.

  Furthermore, the range that can be clearly seen can be limited to the pull ring 13. For example, as shown in FIG. 2A, an annular transparent region 32 can be formed on the top surface 20, and the other part can be a translucent or opaque region 33. That is, the ring of the pull ring 13 provided in the cap body 1 is arranged so as to coincide with the annular transparent region 32. In such a case, even when the upper lid 2 is once removed and the pull ring 13 is pulled and the score 10 is slightly torn, the fact can be clearly recognized. That is, as shown in FIG. 2B, even when the position of the ring of the pull ring 13 is slightly shifted, it can be easily recognized.

  In the present invention, in order to clearly recognize the pull ring 13, it is most preferable that the upper lid 2 is colorless and the cap body 1 is colored.

  In the above-described specific example, the upper lid 2 is attached to the cap body 1 by screw engagement. Of course, the present invention can also be applied to a container lid of the type in which the upper lid 2 is hinged to the cap body 1. Needless to say.

  The cap body 1 and the upper lid 2 described above are manufactured by injection molding or compression molding using a known thermoplastic resin, but the container lid is molded from a transparent material to form a transparent region. In this case, when the mold surface is a mirror surface and a semi-transparent region is formed, the mold surface may be a rough surface, depending on the combination with the type and composition of the resin (for example, a colorant such as a pigment). A transparent region can be formed in a predetermined portion of the upper lid. Of course, the entire container lid is made transparent, or a transparent region and an opaque region are formed by a transparent material and an opaque material by two-color molding or the like. You can also.

  According to the present invention described above, the opening history clarification function can be provided with a simple configuration without using a special member such as a TE band, which is extremely advantageous in terms of cost and productivity.

It is the top view (a), side sectional view (b), and bottom view (c) of the container lid with a pull ring of the present invention. It is explanatory drawing for demonstrating the function in other embodiment of the container lid with a pull ring of this invention.
