In the container lid of Patent Document 2, the upper lid is attached to the mouth and neck of the container, and the trunk and the skirt wall positioned below the upper lid are both attached around the mouth and neck. With such a structure, there is a problem related to the following airtightness before the upper lid is opened.
In Patent Document 2, if the upper lid is strongly attached to the mouth / neck portion of the container in order to improve the hermeticity, a strong force is required when the upper lid is detached from the mouth / neck portion. Therefore, it is only necessary to improve the sealing property between the trunk or the skirt wall and the mouth and neck, but a cut line for tearing the trunk is formed between the upper lid and the skirt wall. If there is this cut line, if the part with the cut line is attached to the mouth and neck by applying a strong force to improve the sealing, the cut line will be cut when the container lid is hit against the mouth and neck. Therefore, it is necessary to loosen a little between the trunk and the mouth and neck. Thus, structural problems arise due to the sealing properties.
In addition, the container lid disclosed in Patent Document 2 forms a band-shaped hinge portion that connects the upper lid and the skirt portion, which is obstructive because the upper lid hangs in a free state at the time of pouring. In order to prevent this, a locking portion of the upper lid is provided on the skirt portion. As described above, when the locking portion is separately formed, the degree of freedom in designing the lid member is lost and the material cost is excessive.

The lower opening score 21 is provided between the upper end inner peripheral surface, and the lower opening score 21 is provided between the lower end inner peripheral surface of the opening band 22 and the upper end inner peripheral surface of the dispensing tube portion 9. That is, after removing the opening band 22, the container can be resealed by inserting the sealing cylinder part 27 of the upper lid into the inner wall of the extraction cylinder part 9.
An opening knob 23 is formed on the back surface of the opening band 22. The opening knob 23 protrudes radially outward from the outer periphery of the opening band 22, extends upward from the tip thereof, and is refracted laterally toward the circumferential direction of the upper lid 4 at the position of the upper lid 4. A pin-shaped bridge 25 that connects the upper lid 4 and the opening knob 23 is formed on the upper end side of the opening knob 23. The bridge 25 holds the tip of the opening knob 23 and is broken by a slight external force by the fingertip.
When the opening knob 23 is pulled in the outer circumferential direction, the connection between the upper lid 4 and the opening knob 23 by the bridge 25 is released, and the upper and lower opening scores 20, 21 are torn, and the opening band 22 and the opening band are opened. The knob 23 is separated from the container lid 1. In addition, a thin portion for connecting the upper opening score 20 and the lower opening score 21 is formed at a position (left end portion) corresponding to the connection portion of the opening band 22 with the opening knob 23.

The upper lid 4 is provided with a sealing cylinder portion 27 on the lower side and a top surface portion 26 on the upper side. The cylindrical sealing cylinder part 27 forms an annular bead 28 protruding outward, and the outer diameter of the annular bead 28 is that of the reseal part 30 (FIG. 3) on the inner peripheral surface on the upper end side of the dispensing cylinder part 9. It is formed slightly larger than the inner diameter. The upper part of the sealing cylinder part 27 is formed with a restriction part 32 that protrudes outward in the circumferential direction at the upper part of the sealing cylinder part 27 and abuts on the upper edge of the extraction cylinder part 9 when resealed. The restricting portion 32 faces downward and has an annular flat surface.
After the unsealing band 22 is left behind, the sealing cylinder part 27 can be fitted into the reseal part 30, and the upper lid 4 can be closed with respect to the upper end opening (reseal part 20) of the dispensing cylinder part 9. By opening the upper lid 4, it is possible to open the plug (see FIGS. 5 and 6).

In addition, an annular outer peripheral wall 35 that protrudes upward from the outer periphery of the top surface wall 33 is formed on the top surface portion 26 of the upper lid 4 so as to surround the top surface wall 33. An opening knob 29 for opening the upper lid 4 is provided on the outer peripheral surface of the outer peripheral wall 35 so that the opening knob 29 protrudes outward from the outer peripheral surface of the outer wall 35 in a bowl shape. Is formed.
One end of a band-shaped connecting band 3 that connects the lid main body 2 and the upper lid 4 is connected to the lower part on the back side of the outer peripheral wall 35, and the other end of the connecting band 3 is on the outer peripheral surface on the back side of the dispensing tube portion 9. It is connected to a substantially middle position in the vertical direction.
Therefore, as shown in FIG. 1, on the back side of the container lid 1, there are a connection band 3, an opening knob 23 for tearing the opening band 22, and a separation knob 16 for tearing the separation band 15. It is arranged. The arm 23 a of the opening knob 23 is adjacent to the connection band 3 on the left and right sides, and the connection band 3 and the separation knob 16 are disposed in the vertical position of the container lid 1 at the same circumferential angle.

Engagement protrusions 37 and 38 are formed on the upper surface of the flat top wall 33 of the upper lid. The engagement protrusions 37 and 38 protrude upward from the top surface of the top wall 33, and as shown in FIG. 2, on one side (below the center line of the drawing) of the center line connecting the front surface to the back surface of the container lid 1. In other words, it is disposed on the side where the separation knob 16 is located. Specifically, the engaging protrusions 37 and 38 have a rectangular parallelepiped shape extending in one direction, one end of the engaging protrusions 37 and 38 is disposed on the center line, and the other end is a side of the container lid 1 (a knob body). 16a). The interval L1 between the engaging protrusions 37 and 38 arranged in parallel is formed to be the same as or slightly smaller than the height of the separation knob 16, and when the upper lid 4 is opened, the engaging protrusions 37, 38 are formed. The separation knob 16 is sandwiched or removed between the recesses formed by the above. The length of one engagement protrusion 37 is shorter than the other engagement protrusion 38 so as not to interfere with the outer peripheral wall 35. The height of the engaging protrusion 37 is the same as or slightly lower than that of the outer peripheral wall 35.
In addition, although the end of the engagement protrusions 37 and 38 was arrange | positioned according to the centerline, if it is the range which can clamp the separation knob 16, the position of the other end side will not be restrict | limited.
Furthermore, the surface between the engagement protrusion 37 and the engagement protrusion 38 may be inclined and extended in a direction away from the surface. By doing so, it becomes possible to easily fix the separation knob 16 between the engagement protrusion 37 and the engagement protrusion 38. In other words, in this case, the height of the separation knob 16 can be set within the distance L1 between the engaging protrusions 37 and 38.

Next, the operation of the container lid according to the embodiment of the present invention will be described.
In the present invention, when the container lid 1 is attached (plugged) to the container opening 7 of the container 6, an extra force is applied to the upper side of the dispensing cylinder part 9 including the dispensing cylinder part 9. Without any load, only the annular upper surface wall 11c of the base 8 is loaded. Therefore, the opening scores 20 and 21, which are thin portions formed on the upper and lower sides of the opening band 22, do not get over a portion larger than the opening scores 20 and 21 when the container lid 1 is stoppered. The opening scores 20, 21 are not damaged. As for the base portion 8, a conventional connection structure with the container mouth portion 7 can be used, and since the portion above the base portion 8 is completely sealed, the sealing property of the container is ensured.

When the container lid 1 is opened, the opening knob 23 is picked and the opening band 22 is turned over so as to be torn. Since the opening scores 20 and 21 are formed on the upper and lower sides of the opening band 22 in the circumferential direction, the opening scores 20 and 21 are broken and the opening band 22 can be removed. The opening tab 23 is disposed adjacent to the connecting band 3, and the opening band 22 starts from the opening tab 23 and breaks toward the opposite side of the connecting band 3. When 3 breaks, it does not get in the way. At the end of the break, the opening band 22 can be torn from the inside of the connecting band 3, and there is no hindrance when the connecting band 3 tears the opening band 22.
In addition, a thin wall portion for connecting the upper opening score 20 and the lower opening score 21 is formed at a position (left end portion) corresponding to the connection portion with the opening knob 23 of the opening band 22. The initial breaking of the score 20, 21 is facilitated.

After the opening band 22 is torn, the lid body 2 and the upper lid 4 are separated, but are connected via the connecting band 3.
When the upper lid 4 is closed by the lid body 2, as shown in FIG. 5, the sealing cylinder portion 27 is fitted to the reseal portion 30 opened at the upper end portion of the dispensing cylinder portion 9, and the restriction portion 32 is resealed. The sealing cylinder part 27 is pushed in until it comes into contact with the upper end of the part 30. Since the annular bead 28 formed in the sealing cylinder portion 27 is in close contact with the reseal portion 30, it is possible to ensure the hermeticity in the container when the upper lid 4 is closed.

When the contents of the container 6 are poured out, the upper lid 4 is used after being removed from the dispensing portion 9 of the lid main body 2, but the upper lid 4 is connected to the lid main body 2 via the connecting band 3 and is lost. There is nothing to do.
When the contents are poured out, the upper lid 4 is supported on the free end side of the connection band 3, so that the upper lid 4 may become an obstacle when the contents are poured. As a means for preventing this, the separation knob 16 is held by the recess between the engaging projections 37 and 38 formed on the upper lid 4 so that the upper lid 4 is held by the separation knob 16 as shown in FIG. . As described above, the upper lid 4 is held by the separation knob 16 so that the upper lid 4 does not get in the way. The separation knob 16 is necessary when the container lid 1 is removed from the container 6 after the container 6 is used, and it is not necessary to form a special holding portion for the upper lid 4, thereby reducing the material cost. When the upper lid 4 is removed, the separation knob 16 is simply held between the engaging protrusions 37 and 38, so that the removal is easy.
After the container 6 is emptied, the container 6 and the container lid 1 are separated as waste separation. In this case, the separation knob 16 is picked and the separation score 12 of the separation band 15 is obtained. Break. Then, the locking state of the separation band 15 and the locking jaw 14 of the container 6 is released, and the container lid 1 can be removed from the container mouth 7.

Thus, this invention provides the container lid 1 which can hold | maintain, without providing the holding | maintenance part of the upper lid 4 at the time of pouring, without losing sealing property before opening the upper lid 4. FIG.
Moreover, the container lid 1 in this embodiment is integrally molded in a molding die in the form as shown in FIGS. The normal container lid does not have the opening band 22 and is integrally formed with the upper lid opened in the horizontal direction. For this reason, the molding die requires a space corresponding to the area of the upper lid and the area of the lid main body (and the connecting member), but in this embodiment, the upper lid 4 and the lid main body 2 are substantially aligned on a straight line. Therefore, there is an effect that the size of the molding die can be reduced without requiring the area of the molding die. Furthermore, after the former molding die (conventional) is molded, it is necessary to close the upper lid to the lid body. However, in the present invention, the upper lid 4 and the lid body 2 are connected via the opening band 22. This has the effect of omitting such work.
