Description

[Detailed description of the invention] The present invention relates to a lid for liquid beverages, etc., and more specifically, a lid top plate on a disc is made of a comparatively rigid material such as paper, and the top plate 11 is provided with a pull tab. This is a lid for an easy-to-open container that has a pull piece for opening.

There are various types of lids for conventional pull-tab-type easy-open containers, but in general, the lid is made of metal with a notch called a score to define an opening piece, and a tension piece called a pull tab is riveted to the opening piece. Although easy-open containers are made of metal, they can be opened without using tools such as a can opener, and because they are easy to open, many containers today are considered easy-open containers. ing.

By the way, when the contents of this easy-to-open container are liquid, people often eat or drink by touching the mouth directly to the opening of the container, so it has been desired to keep the area around the opening hygienic.

However, with easy-to-open containers, it is difficult to keep only the area around the opening sanitary, so the entire top surface of the container is covered with a cap made of a thin synthetic resin film to keep the entire lid including the opening clean. When using a cap made of a thin resin film like the one described above, the cap may come off when the container is transported or stored, and when opening the container, it is necessary to remove the cap and then pull up the pull tab twice. There were drawbacks such as.

In contrast to the conventional pull-tab type easy-open container as described above, the present invention has a pull tab made of alloy resin and a sealing body 20 that fills the opening, and a cover that covers the sealing body 20 is integrated with a handle that serves as a pull tab. This easy-to-open container is easy to manufacture, can be opened as easily as a conventional metal pull-tab-type easy-to-open container, and can keep the opening portion 12 clean.

That is, as shown in FIGS. 1 and 3, the easy-open container according to the present invention has a lid 1o having an opening 12 having an area relatively small compared to the total area of the top plate 11. A sealed body 2 made of thermoplastic synthetic resin and equipped with an opening handle 14
An opening cover 24 having the shape of 0 and covering the entire area of the sealing body 20 extends horizontally from the base 15 of the opening handle 14 to the upper surface of the sealing body 2o, and also extends from the bottom of the periphery of the sealing body 20. An inner annular lower protrusion 27 is provided on the top plate 11 .
An outer annular downward protrusion 2 along the opening portion 12 on the lower side of the
6 are connected to the inner annular lower projection 27 via the thin wall portion 23, and a cover guide 29 connected to the outer annular lower projection 26 is provided below the outer periphery of the top plate 11. Easy-to-open lid with cover.

As described above, since the present invention has the opening cover 24 that covers the entire area of the sealing body 20, the opening part 12 and its surroundings can be kept clean, and the opening cover 24 is a pull tab. Since it is integrated with the handle 14, the opening cover 24 and sealing body 20 can be removed and the container opened by simply pulling up the handle 14, and these opening handle 14, sealing body 20, etc. can be combined. Since it is made of resin and integrally molded, it can be manufactured extremely easily by injection molding, etc., and the outer annular downward protrusion along the opening portion 12 is formed on the rigid disc-shaped top plate 11. Since the sealing body 26 is molded and added to the top plate 11, the sealing body 2 is securely and firmly attached to the top plate 11.
0 can be attached, and the outer annular lower projecting body 2
6 and the inner annular lower protrusion 27 on the lower side of the periphery of the sealing body 20, the opening can be made easy and reliable.

Furthermore, the covering guide 29 has the effect of making the attachment easy and reliable when attaching the lid 10 according to the present invention to the container body.

The embodiment of the present invention as described above will be described in detail with reference to the drawings.
As shown in FIG. 1, in the top plate 11 of the circular lid body 10 made of a relatively rigid material such as paper, an opening portion 12 having a relatively small area relative to the total area of the top plate 11 is punched out. A sealing body 20 with a ring-shaped opening puller 14 attached to 12
As shown in FIG. 3, at the base 15 of the unsealing handle 14, an opening cover 24 that covers at least the entire area of the sealing body 20 is provided extending horizontally on the upper surface of the sealing body 20.

An inner annular lower protrusion 27 is formed below the periphery 21 of the sealing body 20, and an inner annular lower protrusion 27 is formed on the lower side of the periphery 21 of the sealing body 20.
A thin wall portion 23 is extended to the lower side of the joint 2 with the top plate 11, and an outer annular lower protrusion 26 is then formed to be joined to the back surface of the top plate 11, thereby forming a sealed body 20 with an opening handle 14. Opening cover 2
4, the inner annular lower projection 27 and the outer annular lower projection 26 are integrally molded into the lid 10.

The opening cover 24 covers the entire area of the sealing body 20 as shown in FIGS.
3, and the peripheral edge 2 of the opening cover 24.
5, it is preferable to form the opening cover 24 so as to be spot-joined onto the top plate 11 to prevent the opening cover 24 from shaking.

As shown in FIGS. 2 and 4, an outer annular lower protrusion 26 at the outer edge of the opening portion of the end surface 13 of the top plate has a circular shape corresponding to the mouth edge of the container, and serves as a cover guide to the periphery of the lid. 29, it is preferable that the outer annular lower projecting body 26 is integrally molded.

However, the outer annular downward projection 26 on the outer side of the sealing body 20
The connecting portion extending from the top to the cover guide 29 is made as thin as possible to allow the cover guide 29 to be integrally formed with the outer annular lower projecting body 26, and the cover body 10 is inserted and fixed into the mouth of the container. To assist in this, when removing the sealing body 20, the thin wall portion 23 between the inner annular lower projection 27 and the outer annular lower projection 26 is torn, and the sealing body 20 is removed from the outer annular lower projection 26 and the covering guide 29. The structure shall be such that it can be easily separated from the

In this way, the present invention not only covers the entire area of the sealed body 20, but also
Since the periphery near the top plate end face 13 close to the opening portion 12 is covered, there is an advantage that the area including the periphery of the top plate 11 is always kept clean before opening.

Since the opening handle 14, the opening cover 24, and the sealing body 20 are integrally molded, there is an advantage that the opening cover 24 can be removed simultaneously with the removal of the sealing body 20 by one action.

Incidentally, the peripheral edge 21 of the sealing body 20 is connected to the inner annular downward projecting body 2.
Since there is no local deformation because it joins with 7, and the end surface 13 of the opening portion of the top plate 11 does not deform locally because it joins with the outer annular lower protrusion 26 on the lower side, there is no force to pull the ring upper opening puller 14 upward. is the joint 22 between the sealing body 20 and the top plate 11
to ensure easy and reliable rupture at joints.

The lower side of the joint 22 between the sealing body 20 and the top plate 11 is made into a thin wall portion 23, and the lower side of the periphery 21 of the sealing body 20 and the lower side of the top plate end face 13 are formed as reinforcing inner sides by sandwiching this thin wall portion 23. Since it includes the annular lower projection 27 and the outer annular lower projection 26, it is easily separated at the joint 22 when the opening handle 14 is pulled up, and the sealing body 20 can be easily removed from the top plate 11.

Further, a sealing body 20, an opening handle 14, an opening cover 24,
Since the inner annular lower projection 27, the outer annular lower projection 26, the cover guide 29, etc. are connected together as appropriate, the lid 10
