Description

[Detailed explanation of the idea] This case relates to unsealed containers.

Openable cans with finger rings are often used for various canned goods, canned drinks, and the like.

This type of can can be opened by hooking your finger on the ring and pulling it up strongly, which is convenient in that no tools are required to open the can.

However, since it is made of metal, the material cost and processing cost are high, and the yield is poor due to deformation, etc. Therefore, the cost is considerably high, and the loss is too large to be disposable.

Also, opening the package requires considerable force.

The present invention seeks to eliminate such conventional drawbacks.

The illustrated embodiment will be described below.

In the figure, 1 is a container body with a rectangular planar shape, and the outer layer of the container body is a plastic-coated aluminum sheet 11.
, the inner layer is made of a laminated material of plastic sheet 12.

Note that the plastic sheet may be the outer layer.

Alternatively, it may be made of plastic alone.

Reference numeral 2 denotes a lid that airtightly closes the mouth 13 of the container body 1; is shaped into a hook-shaped cross section, is fitted into the opening 13, and is welded and integrated with appropriate welding means.

Further, the lid body 2 is provided with a notch 24 that goes around the circumferential edge 23 in the lid body 21, and leaves thin torn pieces 25 at various places in the notch.

Furthermore, in the lid body 21, a window hole 26 is formed at the negative corner,
A blade 27 having a T-shaped longitudinal section and a blade 27a at the lower end is disposed at the window hole, and the - side end of the blade is connected to the lid peripheral edge 23.
The blade 27a is integrally connected via the thin breaking line 28.
is located in the window hole 26, and near the window hole 26 and the blade body 27, the integrally molded finger rest is a ring 29,
That is, the inner circular window hole 30 and the outer edged annular cut 3
1 and is slightly lifted from the plastic-coated aluminum sheet 22 and has a finger rest with a ring 29 with its base 29a facing the blade body 27.

Note that the plastic-coated aluminum sheet is an aluminum sheet with plastic layers provided on both the front and back sides.

When in use, the lid 2 is fitted onto the opening 13 of the container body 1 containing the contents in advance, and the opening 13 is airtightly closed by welding them together using appropriate welding means. ,use.

Next, when opening the package, first push down the blade 27.

Then, the plastic-coated aluminum sheet 22 is partially pierced by the blade 27a at the lower end of the blade.

Therefore, for the finger rest, raise the ring 29 and place your finger on it.
When the container body 1 is strongly pulled upward, the plastic-covered aluminum sheet 22 is broken along the notches 24 due to the above-mentioned partial breakage, and the container body 1 is opened wide.

Further, after pushing down the blade 27 and breaking through a part of the plastic-coated aluminum sheet 22 with the blade 27a, the blade 27 is
If 7 is broken and removed at the thin break line 28, a small hole for pouring will be opened in the window hole 26.

According to this proposal, the main part can be constructed by integral molding of plastic, the structure is simple, material costs, processing costs, etc. can be significantly reduced, deformation is difficult to occur, the yield is the same as above, and the yield is considerably high. Cost reductions can be achieved, there is little loss even when disposable, and the function as a conventional can and container is almost the same.

When the package is opened, the plastic-coated aluminum sheet 22 is broken, and at the time of breakage, the force guided by the notch 24 is efficiently concentrated at the breakage point, and the blade 27 initially This causes the finger rest to break due to the tension of the ring 29.
Breaking and opening can be performed easily and easily, and thereby the container body 1 can be opened wide.

Furthermore, using only the blade 27, by pushing down the blade, the blade 27a breaks through a part of the plastic-coated aluminum sheet 22, and by breaking and removing the blade at the thin break line 28, the window hole is opened. At 26, a small hole for dispensing can be made very easily, and there is no obstacle to dispensing, and no inconvenience occurs.
