[0003]

However, in the conventional cap with a lid described above, when the lid (200) shown in FIG. 3 is mounted on the cap body (100), the center of the cap body and the lid are closed. Since the center is easily displaced due to distortion during molding or the like, two rows of thin strip-shaped hinge portions (301, the other not shown) connecting the cap body and the lid portion.
Was twisted or cut.

Further, when the lid is opened to incline the container to pour out the contents, the lid may fall forward to prevent the pour out of the contents.

The present invention has been made to solve the above-mentioned problem of the conventional cap with a lid. When the lid is mounted on the cap body, the center of the cap body and the center of the lid naturally fit together. The two rows of thin strip-shaped hinges that connect the cap body and the lid are not twisted or cut, and when pouring out the contents, the lid falls forward to prevent pouring. The present invention is to provide a cap with a lid made of polyethylene without any.

[0006]

According to the present invention, as shown in FIGS. 1A and 1B, a top plate (120) is provided inside a cylindrical peripheral wall (110) of a cap body (100). And a column (142) having a pull ring (143) at its tip protruding below the inside of the injection tube to form an annular thin weak line (141) on the outer periphery. In a cap provided with a plate (140) and connected to a lid (200) via two rows of hinges (301 and 302) parallel to the upper end of one side of the peripheral wall, the cap body (100)
The two rows of hinge portions (301 and 30) of the peripheral wall (110) of

A cap (10) with a lid (10), wherein a temporary fixing and positioning projection (230) is provided at the upper end of the peripheral wall (210) of the lid (200) corresponding to the vertical groove so as to slidably contact the vertical groove on a curved surface. ).

[0007]

The container having the cap with the lid of the present invention attached to the mouth has a vertical groove provided on the peripheral wall of the cap body and a temporary groove provided on the peripheral wall of the lid when the lid is attached to the cap body. The locking and positioning projections engage with each other while sliding on each other's curved surfaces, so that the center of the lid part naturally fits the center of the cap body, and two rows of hinges connecting the cap body and the lid part. The part is not twisted or cut.

Further, when the lid is opened and the container is tilted to pour out the contents, even if the lid falls forward,
Since the distal end surface of the temporary fixing and positioning projection of the lid portion abuts on the distal end surface of the vertical groove of the cap body, it does not hinder the pouring of the contents.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a cap with a lid according to the present invention;
As shown in FIGS. 1 (a) and 1 (b), a top plate (120) is provided in the middle of a height direction inside a cylindrical peripheral wall (110) of a cap body (100) to form an upper end. An ejection tube (130) having a spout is provided upright, and a column (14) having a pull ring (143) at the tip is provided below the inside of the ejection tube.
2) is provided, and a sealing plate (140) having an annular thin fragile line (141) formed on the outer periphery is provided, and two rows of thin strip-shaped hinge portions (301 and 302) parallel to the upper end of one side of the peripheral wall are provided. And a vertical groove having a semicircular cross section between two rows of hinges (301 and 302) on the peripheral wall (110) of the cap body (100). (150) is provided from the front end to the top plate position, and the temporary fixing and positioning projections are engaged with the upper ends of the peripheral walls (220) of the lid (200) corresponding to the vertical grooves by slidingly engaging the vertical grooves with each other. (230). The cap with a lid of the present invention is manufactured by injection molding using polyethylene.
The cap body and the lid are integrally formed.

Then, as shown in FIG. 2, on the lower inner surface of the peripheral wall (110) of the cap body (100), for example, an occlusal ring (113) for engaging with the occlusal ring (21) at the mouth of the container (20) is provided. Alternatively, an engagement ring with a threaded portion at the mouth of the container is provided, and an engaging ring (112) with an engagement ring (112) with the lid (200) at the outside of the tip is provided inside the upper end surface of the peripheral wall (110). (111) is provided, and a sealing ring (121) is provided on the lower surface of the top plate (120) in close contact with the inner surface of the mouth of the container, and a peripheral wall corresponding to the hinge portion (301, the other is not shown) of the lid portion is provided. Opening knob (212) on the outer peripheral surface of (210)
Is provided, and an occlusal ring (21)
1) is provided, and a sealing ring (221) is provided on the inner surface of the top plate (220) of the lid portion so as to be in close contact with the inner surface of the upper end portion of the discharging cylinder (130) of the cap body.

Further, the cap body, the hinge part and the lid part are usually integrally formed by injection molding using low-density polyethylene.

The cap with the lid of the present invention was attached to the mouth of the container filled with the contents, and the lid was opened and the container was inclined to pour out the contents. Did not obstruct the dispensing of the contents. Also, when the lid is attached to the cap body, the hinge is twisted,
It was not cut.

[0013]

According to the container of the present invention having the cap with the lid attached to the mouth, when the lid is attached to the cap main body, the vertical groove of the cap main body and the temporary fixing and positioning projection of the lid are formed. The sliding of the curved surfaces causes the center of the lid to naturally align with the center of the cap body, so that the hinge connecting the cap body and the lid is not twisted or cut.

Further, when the contents are poured out, the lids fall forward by the vertical grooves of the peripheral wall of the cap body and the temporary fixing and positioning projections of the peripheral wall of the lids, and the contents are discharged. There is no hindrance.
