Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an opening device for opening a spout provided on the top of a beverage container and covered with a pull tab, and a packaging container.
[0002]
[Prior art]
As a packaging container having a lip provided on the top of a beverage container and opening a pull tab covering a spout, for example, one described in International Publication WO 00/48914 is known. FIG. 4 shows the structure of the container, in which a lip 3 provided on the top 2 of the beverage container 1 and a pull tab 5 covering the spout 4 are formed.
[0003]
[Problems to be solved by the invention]
The opening device and the packaging container for opening the spout provided on the top of the beverage container and covered with the pull tab and protected by the inner film are required to have easy opening performance and a clean opening cross section. SUMMARY OF THE INVENTION It is an object of the present invention to provide an opening device and a packaging container thereof, which can easily open a container spout and obtain a good opening cross section without any unnecessary and unnecessary breakage.
[0004]
[Means for Solving the Problems]
In order to solve this problem, the present invention forms an opening start point on a part of the pull tab and the inner film in conjunction with the opening operation when opening the container spout, and further opening from the opening start point. It is configured to proceed.
[0005]
Thereby, easy opening performance and a clean opening cross section can be obtained.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
The invention according to claim 1 of the present invention is an opening device for a beverage container having a spout at the top covered by a pull tab and protected by an inner film,
A lip provided between the outer edge of the top and one edge of the spout;
A handle that is one edge of the spout and is sealed on the pull tab,
The handle is formed integrally with the lip and substantially surrounds the remaining edge of the spout. An opening device characterized in that the opening device is broken to form an opening start point.
[0007]
The invention according to claim 2 is a beverage container having a spout covered by a pull tab and protected by an inner film and an opening device for opening the spout at the top, wherein the opening device has an outer edge of the top. And a lip provided between one edge of the spout and
A handle that is one edge of the spout and is sealed on the pull tab,
The handle is formed integrally with the lip and substantially surrounds the remaining edge of the spout. A packaging container which is broken to form an opening start point.
[0008]
A lip provided near the outer edge of the top facilitates drinking by indicating the location of the lips of the consumer when the consumer drinks the filled beverage, and is sealed on the pull tab on one edge of the spout. When the pull tab is peeled off at the time of opening, the handle is easy to grasp by the consumer, and the pull tab is peeled off substantially in a straight line to enable easy opening performance and a clean opening breaking surface, and is formed integrally with the lip. A support substantially surrounding the remaining edge of the spout suggests / adjusts the direction of the pull tab peeling action by the handle, and raising the handle at one end causes the handle to break the pull tab and a portion of the inner film at the other end. Since the opening opening point is formed, the breaking force is concentrated on the opening point, and has an effect that a quick inner film breaking and a sharp breaking surface can be performed.
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0009]
(Embodiment 1)
FIG. 1 shows an opening device according to an embodiment of the present invention and a part of a container provided with the opening device. In FIG. 1, a beverage container 1 having a spout (not shown) covered with a pull tab 5 and an opening device 9 for opening the spout on a top portion 2, wherein the opening device 9 is an outer edge of the top portion 2. And a lip 3 provided between the lip 3 and one edge of the spout, a handle 7 which is an edge of the spout and sealed on the pull tab, and a lip formed integrally with the lip and the rest of the spout And the support 8 substantially surrounds the edge of the container. When the container is opened, when the handle is raised at one end, the protrusion 8 at the other end breaks the pull tab 5 and a part of the inner film to form an opening start point. .
[0010]
In this embodiment, the opening device 9 is integrally molded of plastic, the lip 3 and the support 6 have a substantially U shape, the handle 7 is one edge of the spout and is sealed on the pull tab and It is integrated with the lip 3 via a weakening line. At the time of opening, it is cut at the weakened line and the opening operation is performed.
[0011]
Next, an embodiment of a method of providing the opening device of the present invention in a packaging container will be described with reference to FIG.
In this embodiment, a spout 4 is formed on the top portion 2 of the beverage container 1, covered with a pull tab 5, and entirely or partially laminated from the inside with an inner film such as polyethylene. In this embodiment, a polyethylene film (layer) or the like is laminated on the pull tab from the inside to protect the cross section of the spout.
The opening device 9 includes a lip 3, a support 6, a handle 7, and a protrusion 8 at one end of the handle. As shown in FIG. 2, the joining with the container 1 is performed by joining the lip of the opening device 9 and the support to the sealing portion 10 outside the pull tab, and joining the handle 7 to the sealing portion 10a on the pull tab.
[0012]
Next, an embodiment of a method of opening a packaging container with the opening device of the present invention will be described with reference to FIG.
The beverage container 1 having a spout covered with a pull tab and an opening device 9 for opening the spout at the top is opened. When opening the container, grasp one end of the handle and pull up.
Due to this rise, the projection 8 at the other end falls to the pull tab side, and the pull tab 5 and a part of the inner film are broken. This break forms the opening start point of the inner film break.
In order to open all the spouts, the handle 7 is further pulled in the direction shown in FIG. By this operation, the pull tab is peeled as it is without being substantially torn, and the inner film is broken along the edge of the spout or at or near the junction between the pull tab and the inner film (layer) from the break opening start point.
[0013]
In addition to the container shape in the above embodiment, the packaging container according to the present invention includes, for example, a hexagonal column, an octagonal column, a tetrahedron, and the like, in addition to a brick (parallel hexahedron).
[0014]
【The invention's effect】
As described above, according to the present invention, the following advantageous effects can be obtained.
A lip provided near the outer edge of the top can assist in drinking when the consumer drinks the filled beverage by easily indicating the location where the lips of the consumer come into contact.
The handle sealed on the pull tab on one edge of the spout makes it easy for consumers to grasp when pulling off the pull tab at the time of opening, the pull tab is peeled off substantially in a straight line, and the opening performance is easy and a clean tearing section Enable.
[0015]
A support molded integrally with the lip and substantially surrounding the remaining edge of the spout suggests / adjusts the direction of the pull tab release operation by the handle.
When the handle is raised at one end, the other end of the handle breaks the pull tab and part of the inner film to form the break point of the inner film. With a large fracture surface.
