DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a container with a cap made of synthetic resin.

[0002]

2. Description of the Related Art A cap made of a synthetic resin cap body and a synthetic resin lid for closing the upper surface of the cap body so that the cap body can be opened and closed is provided. Containers are widely used.

[0003]

In recent years, wastes have been separated and collected to reduce wastes and to reuse materials.

[0004] Even in the above-mentioned container, since the material of the container body and the cap are usually made of different materials, it is desirable to remove the cap from the container body and dispose them separately. Since it is tightly fitted so that it does not easily come off, it is difficult to remove it, and it is often discarded with the cap on.

[0005] The present invention is directed to a cap which, when a horizontal plate attached to a part of the cap body peripheral wall is pulled up, a part of the cap body peripheral wall is broken within a certain range from the lower end to the upper end of the peripheral wall, and the cap is further pulled up. The entire body is provided so that it can be easily removed from the mouth and neck of the container body.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, a conventionally known structural portion will be described below. Reference numeral 1 denotes a container body, and a mouth and neck 2 is erected from the upper end of a body via a tapered shoulder having an upper small diameter. A first engaging ridge 3 is provided around the outer periphery of the upper end of the mouth and neck, and a ridge 4 is provided below the first engaging ridge 3. The container may be made of a synthetic resin or glass, and the material is not limited.

A synthetic resin cap 11 is fitted to the upper end of the mouth and neck. The cap comprises a cap body and a lid for closing the upper surface of the cap body so as to be openable and closable. The cap body 12 comprises a first peripheral wall extending from the outer periphery of the flange-shaped top plate 13 placed on the upper end surface of the mouth and neck portion 2. The second engaging projection 15 provided on the inner surface of the peripheral wall is engaged with the lower surface of the first engaging projection 3 so as not to be pulled out. Further, the fitting tube 16 for sealing is hung from the flange-shaped top plate 13 by fitting it to the inner surface of the mouth and neck portion 2. Further, a spouting cylinder 17 is provided which rises upward from the inner part upper surface of the flanged top plate so as to expand the upper end upward and outward, and from the front part of the flanged top plate, a curved surface for fitting a lid outer peripheral wall described later. The ridge 18 is standing.

Reference numeral 19 denotes a lid, which is formed by suspending a sealing cylinder 20 water-tightly fitted on the inner surface of the above-described dispensing cylinder 17 from the lower surface of the top wall 21 and suspending the outer peripheral wall 22 from the outer periphery of the top wall. The lower end surface of the outer peripheral wall is placed on the upper surface of the outer peripheral portion of the cap main body flanged top plate 13. From the lower end of the front surface of the outer peripheral wall, a finger hook 23 for opening the lid may be projected forward.

The upper end of the rear surface of the first peripheral wall 14 of the cap body and the lower end of the rear surface of the outer peripheral wall 22 of the lid are connected by a hinge 24 to form the cap body and the lid integrally. In addition, a fourth engaging ridge is provided laterally on the inner surface of the lower end of the front portion of the lid outer peripheral wall 22 to a certain extent, and is engaged with the lower surface of the third engaging ridge provided on the front surface of the upper end of the curved ridge 18 of the cap body. By doing so, the fitting of the lid 19 to the cap body can be ensured.

In the present invention, the first of the cap body 12 is
The front part of the upper half of the peripheral wall is used as a connecting plate part 31, and first thin vertical grooves 32, 32 are vertically provided on both left and right sides of the connecting plate part. Thin transverse grooves 33, 33 of approximately the same length are provided horizontally, and second thin vertical grooves 34, 34 are vertically provided from the respective ends of the thin transverse grooves to the lower end of the first peripheral wall. The first peripheral wall portion below the connecting plate portion 31 is a first horizontal plate 35. Furthermore, the first horizontal plate 35
A second horizontal plate 36 is provided horizontally along the front surface from one end to the other end of the first and second horizontal plates, and the right and left ends of the first and second horizontal plates are connected to each other. In the illustrated example, the overhang plate 37 protrudes forward from the upper edge in the left-right direction of the second horizontal plate 36, and the first horizontal plate extends from the left and right side edges and the front edge of the overhang plate.
A covering plate 38 having substantially the same vertical width as that of 35 is hung down, and the composite plate and a second horizontal plate portion behind the composite plate form a knob 39 for pulling up the second horizontal plate. The first and second thin vertical grooves 32 and 34 and the thin horizontal groove 33 are formed so as to be breakable by forcible lifting of the second horizontal plate 36.

The container with a cap is used by opening the lid 19 to pour out the liquid in the container and closing the lid.

After use, when disposing, hold the knob 39 or the middle part in the left-right direction of the second horizontal plate 36, and pull it upward and outward. First, the second thin vertical grooves 34, 34 Then, as shown in FIG. 4, the thin horizontal grooves 33, 33 are broken from the outer end to the lower ends of the first thin vertical grooves 32, 32, and the first thin vertical grooves 32, 32 are further pulled upward to form the first thin vertical grooves 32, 32. It can be broken from the lower end to the upper end. In this state, the portion of the second engaging ridge 15 on the inner surface of the first horizontal plate 35 is disengaged from the lower surface of the first engaging ridge 3. Therefore, when the portion is further pulled upward, the front edge portion of the flange-shaped top plate 13 is raised. As a result, the cap body 12 is easily detached from the outer surface of the mouth and neck of the container body.

[0015]

According to the present invention, the second horizontal plate is provided along the front surface from one end to the other end of the first horizontal plate 35.
Since the both ends of the first and second horizontal plates are connected to each other, the first horizontal plate 35 which forms a part of the first peripheral wall of the cap body and fits on the outer surface of the mouth and neck portion is provided. Since the second horizontal plate 36 is not fitted to the outer surface of the mouth and neck, it is easy to pull it upward, and the first and second thin vertical grooves 34, 34 and the thin Since the lateral groove 33 is breakable,
By pulling up the second horizontal plate, the front portion of the cap body first peripheral wall 14 can be broken from the lower end to the upper end. Further, the second engaging ridge 15 portion of the first horizontal plate 35 can be removed from the front portion of the first engaging ridge 3 of the mouth and neck portion, so that the second
The cap body 12 is removed from the container body neck by pulling the horizontal plate 36 upward, and thus the cap is removed from the container body.
11 can be easily separated.

By forming the knob 39 for pulling up the second horizontal plate in the middle of the second horizontal plate 36 in the left-right direction as in claim 2, the second horizontal plate can be pulled up directly. The second horizontal plate 36 can be pulled up through the knob, and the first
Partial tearing of the peripheral wall 14 can be facilitated.
