Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a stay-on type easy-open container lid that opens a portion of the panel surface by breaking the score line.

(Prior Art) Conventionally, this type of easy-open container lid has a panel surface a as shown in FIGS. 9 and 10.
form a score line b in order to open a part of it,
In a container lid e in which a lifting lever d for opening is provided on a rivet c formed on a panel surface a, the score line b is connected to a curved first score line along the outer periphery of the rivet c on the tip f side of the pulling lever d. g, the starting end is connected to one end h of the first score line g, and the panel surface a
The starting end l is directed to the side of the pulling lever d near the other end m of the first score line g via a folded part k that is reversed near the peripheral edge i and faces in the direction of the side edge j of the pulling lever d. It is composed of a second score line n extending outward from the edge j, and a discontinuous portion o of the score line is formed between the other end m of the first score line g and the extreme end l of the second score line n. Things are known. When opening the container lid e attached to the container, first pull up the knob d' of the lift lever d and first
break the first score line g, then push the knob d' of the pulling lever d forward using the rivet c as a fulcrum, and move the tip f of the lifting lever d to the panel surface surrounded by the second score line n. A is press-contacted from above to break the second score line n to unseal a part of the panel surface a to form an unsealed part.

However, in such a configuration, since the opening area formed by the breakage of the score line b is small, there is an inconvenience that it takes time to take out the contents in the container if the contents are highly viscous.

Therefore, when the opening area is increased, the distance between the tip f of the pull-up lever d and the second score line n is wide, so the pull-up lever d needs to be opened in order to open the panel surface a.
When pulling up the knob d' and then pushing the knob d' forward to press the tip f of the pull-up lever d against the panel surface a and break the second score line n, the pushing force of the pull-up lever d is The second part was not conveyed sufficiently.
There is a problem in that an extremely strong pressing force is required to break the score line n.

(Problems to be Solved by the Invention) The present invention solves these conventional problems and allows the container lid to break the score line without any problem even if the pushing force of the pull-up lever is small, allowing the panel surface to be opened widely. This is what we are trying to provide.

(Means for Solving the Problems) The present invention has been made to solve the above problems, and includes forming a score line on the panel surface for opening a part of the package, and forming a score line within the score line. In a container lid in which a pull-up lever for opening is provided on a rivet formed on the panel surface of the container lid, the score line is connected to a substantially arc-shaped first score line along the outer circumference of the rivet on the tip side of the pull-up lever, and the starting end is connected to the first score line. A second score line that connects to approximately the center of the score line, extends further from the tip of the pull-up lever, and has its end near the periphery of the panel surface, and each start end is connected to the end of the second score line. , which extend in opposite directions from their respective starting ends, bend along the peripheral edge of the panel surface, and extend along the outer side edge of the pull-up lever via the bent portion toward the outside of the side edge of the pull-up lever. a third and fourth score line whose ends reach near the end of the first score line, and a score line between the end of the first score line and each end of the third and fourth score lines, respectively. forming a discontinuous portion of the first score line, and extending each side edge of the pull-up lever between the discontinuous portions of the score line and at least two-thirds of the distance between the discontinuous portions from the end of the first score line. It is characterized by being placed on both sides.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

1 to 6 show one example of implementing the present invention.

In the drawing, reference numeral 1 denotes a container lid made of commonly used aluminum or other metal thin plate material, and the container lid 1 has a score line 3 formed on its panel surface 2 for opening a part of the container, and the score line A rivet 4 formed on the panel surface 2 outside 3 is provided with a pull-up lever 5 for opening which has a bifurcated tip.

In the present invention, the score line 3 is replaced with a first score line 6 as shown in FIGS.
It is composed of a second score line 7, a third score line 8, and a fourth score line 9. That is, the first score line 6 has a substantially arc shape formed along the outer periphery of the rivet 4 on the side of the tip 5a of the pulling lever 5 with a gap therebetween.
The second score line 7 connects a starting end 7a to the approximate center of the first score line 6, extends further from the tip 5a of the pull-up lever 5, and has an end 7b connected to the peripheral edge 10 of the panel 2.
It is a straight line formed all the way to the vicinity. Further, the third and fourth score lines 8 and 9 are at the respective starting ends 8a,
9a is connected to the extreme end 7b of the second score line 7, extends in opposite directions from the respective starting ends 8a and 9a, and is bent along the peripheral edge 10 of the panel surface 2 so as to connect to the outer side edge 5b of the pulling lever 5. Bent portions 8b, 9b facing toward
Along the outer side edge 5b of the pull lever 5, the respective extreme ends 8c, 9c are connected to the end 6 of the first score line 6.
It has a substantially arc shape formed up to the vicinity of a.

Discontinuous portions 11 of the score line were formed between the end 6a of the first score line 6 and the extreme ends 8c, 9c of the third and fourth score lines 8, 9, respectively.

Further, an annular protrusion 12 that protrudes upward from the panel surface 2a surrounded by the second score line 7 and the third score line 8
, and the second score line 7 and the fourth score line 9
A recessed portion 13 recessed downward is formed in the panel surface 2b surrounded by. Further, the tip of the pull-up lever 5 is bifurcated, and the rear end thereof is provided with a knob portion 5c, and each of the opposite side edges 5b of the pull-up lever 5 is bifurcated.
Between the discontinuous portions 11 of the score line formed between the end 6a of the score line 6 and the extreme ends 8c, 9c of the third and fourth score lines 8, 9, and between the first score line 6 The distance H between the discontinuous portion 11 from the end 6a of
It was formed so as to be disposed at an outer position of 2/3 of the hole and fixed to the rivet 4.

In the drawings, reference numeral 14 indicates a convex strip formed along the outer periphery of the third and fourth score lines 8 and 9 on the panel surface 2 at a distance, and reference numeral 15 indicates a knob portion 5c of the pull-up lever 5 on the panel surface 2. This is a recess formed at a facing position.

With the above structure, when used as a container lid, when the knob 5c of the pull-up lever 5 is grasped and pulled upward, the first score line 6 formed along the outer periphery of the rivet 4 as shown in FIG. Then, the connection part A with the end 7a of the second score line 7 is broken, and then the first score line 6 and the second score line 6 are broken as shown by the arrow B.
The score line 7 is broken toward its extreme end 7b. While continuing to pull the knob 5c of the pull-up lever 5 upward, move forward, that is, at the extreme end 7 of the second score line 7.
When pushed out to the b side, the tip 5a of the pulling lever 5 descends using the rivet 4 as a fulcrum, and one of the tip 5a presses the panel surface 2a having the protrusion 12, and as shown by the arrow C in FIG. The score line 8 is broken from its starting end 8a through the bent part 8b to the starting end 8c, and the panel surface 2a surrounded by the second score line 7 and the third score line 8 is opened.

Also, a little later, the tip 5 of the pull-up lever 5
The other side of the panel a presses the panel surface 2b having the recessed part 13 to break the fourth score line 9 from its starting end 9a through the bent part 9b to the starting end 9c as shown by the arrow D in FIG. The panel surface 2b surrounded by the second score line 7 and the fourth score line 9 is opened.

Therefore, the panel surface 2 can be opened in two stages with the second score line 7 as a border: the first panel surface 2a and the second half panel surface 2b. Since the score line 3 can be broken by the pressing force, the size of the panel surface 2 to be opened can be increased. Further, each of the both side edges 5b of the pull-up lever 5 is located between the discontinuous portions 11 of the score lines on the panel surface 2, and the first score line 6
2/3 of the distance H between the discontinuous portion 11 from the end 6a of
Since the distance between the third and fourth score lines 8 and 9 on both side edges 5b of the pull-up lever 5 can be narrowed, the second score line 7 and the third score line 8 can be narrowed.
The panel surface 2a and the second score line 7 surrounded by
When opening the panel surface 2b surrounded by the and fourth score lines 9, the pressing force of the pull-up lever 5 that presses both panel surfaces 2a and 2b is reliably transmitted to the third and fourth score lines 8 and 9. It is possible to accurately break the score lines 8, 9 from their starting ends 8a, 9a to their extreme ends 8c, 9c.

Furthermore, since a discontinuous portion 11 of the score line was formed between the end 6a of the first score line 6 and the respective extreme ends 8c, 9c of the third and fourth score lines 8, 9, each score line 6, Both panel surfaces 2a and 2b opened by breaking 7, 8, and 9 are connected at the discontinuous portion 11 and do not separate from the panel surface 2, so there is no problem of the pulling lever 5 being separated and thrown away. .

Further, a protrusion 12 is provided on the panel surface 2a surrounded by the second score line 7 and the third score line 8, and a recess 13 is provided on the panel surface 2b surrounded by the second score line 7 and the fourth score line 9. Since panel surfaces 2a and 2b are provided respectively,
is reinforced so that when the pulling lever 5 is pulled and pushed out, the panel surface becomes difficult to bend, and one of the tips 5a of the pulling lever 5 presses the panel surface 2a provided with the protrusion 12 to open the package for the first time. The other half of the tip 5a of the pull-up lever 5 presses the panel surface 2b provided with the recessed portion 13, and the second half of the unsealing can be performed in two steps in an orderly and reliable manner, so that the panel surface 2 can be opened largely. I can do it.

7 and 8 show other embodiments of the present invention, in which the tip end 5a of the pull-up lever 5 is formed into a bifurcated shape, and the length of one crotch portion 16a is longer than the other crotch portion 16b. It was formed.

Also, in the drawings, reference numeral 17 indicates a panel surface 2a surrounded by the second score line 7 and the third score line 8, and a panel surface 2b surrounded by the second score line 7 and the fourth score line 9.
This is an annular protrusion that protrudes upward, provided on each of the above.

When using such a configuration, the second
Among the panel surface 2a surrounded by the score line 7 and the third score line 8 and the panel surface 2a surrounded by the second score line 7 and the fourth score line 9, the crotch of the pull-up lever 5 is longer. The tip 5a of the shorter crotch 16a presses against the panel surface 2a to break the score line for the first opening, and then the tip 5a of the shorter crotch 16b presses against the panel surface 2b. The second half of the opening after breaking the score line can be performed in two steps in an orderly and reliable manner.

(Effect of the invention) As described above, according to the present invention, the first score line, which is approximately arc-shaped along the outer periphery of the rivet on the tip side of the pulling lever, and the extreme end are connected to approximately the center of the first score line, and the rivet is pulled up. a second score line that extends further from the tip of the lever and has a starting end near the peripheral edge of the panel surface; The wires are bent along the peripheral edge of the panel surface and extend along the outer side edge of the pull-up lever via the bent portion facing outward from the side edge of the pull-up lever, and each end is near the end of the first score line. This is done by breaking the score line consisting of the third and fourth score lines.

Therefore, the opening of the panel surface is performed at the beginning of the panel surface surrounded by the second score line and the third score line due to the breakage of the third score line following the breakage of the first score line and the second score line. This can be done in two stages: opening the 4th score line, and then opening the latter half of the panel surrounded by the 2nd and 4th score lines due to the breakage of the 4th score line. The panel surface could be opened largely with pressure, and discontinuous portions of the score line were formed between the end of the first score line and the ends of the third and fourth score lines, so the score line Since the opened panel surface does not separate from the container lid due to breakage, there is no problem such as the pull-up lever being separated and thrown away.

and between the discontinuous portions of the score line formed between the end of the first score line and each end of the third and fourth score lines on both sides of the pull-up lever, and between the first score line Since the discontinuous portions are disposed at least 2/3 of the distance between the discontinuous portions from the ends of the It is effective to provide an easy-open container lid capable of surely transmitting the pressing force of a lever to both score lines and appropriately breaking both score lines from their starting ends to their ends.
