Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a metal easy-open can lid that prevents the tab from separating from the can panel.

A circular panel part in the center part, a countersink part on the periphery, a joint S-type mochi for connecting with the can body following the countersink part, and a score line surrounded by a circle in the armpit panel part. The removal part, the lid, and the tab (4JA, this tab is completely separated from the panel part together with the IIE removal part) installed in the removal part as a means for cutting off the score line value worked. Metal easy-open can lids are well known and are still widely used as closures for beverage cans and non-beverage liquid cans.

With this type of can, if the separated removal part with the tab attached is carelessly discarded, the tab with the removal part may cause unexpected injury, and it is difficult to clean the scattered tabs with the removal part. For this reason, many metal easy-open cans with tabs have been proposed in which the tab is fixed to the panel even after opening. However, many of them are difficult to mass-produce (they have a difficult structure, -〇 operation is complicated, *the broken part completely crosses the panel part and is so long that it flops), and when opening the can or drinking the contents of the can, the long and thin broken part is However, there are still some points that cannot be said to be practical, such as the a-stump part of the stump can injure fingers, nose, feet, etc., and it has not been used conveniently in practice.

A representative example of metal easy-open cans with small tabs, which are currently in widespread use, is JP-A-51-82.
It is called a "stay-on tab" disclosed in the lss issue.

This is a picture with a reference text, aluminum can 1121
In the panel portion 22 in the central portion of the panel section 22, a score line 25 defining a generally elliptical i[cut section 23 and having spaced apart edges lI24. The front end 27 that serves as the breaking part is the breaking part 2.
3. On the other hand, the rear 1111s28, which is used for pushing up (or pulling up), is i! It is outside of 1523, and the score line is 25, 26 neighborhood f)ll
Wft part 23 (Outside Te +) Panel part 2 depending on the head
2 and a tab 29 fixed to the holder. In addition, 3
o surrounds the fixation ll31 of the tab 29 in a C shape,
This is a slit that allows the tab 29 to be pushed up into a container.

To open this can lid, first open the rear 111 of the tab 29.
When you push up (or pull up) the end part 28 by inserting your finger into the negative part of s28, the front end part 27 becomes the point of action due to the lever action using the 1wU attachment part 31 as a fulcrum.
Since it is strongly pressed, the part ρ of the score 1ilzs that is close to the tab fixing part 31 is approximately the length of the entire score line (in Figure 1, from the end s24 to the part closest to the chest edge of the panel part 22 The 137825 portion up to the position 137825) breaks instantly, and when the end 28 is pushed up to the east, the unbroken portion of the score line 25 breaks one after another following the +lLI portion. When the tab 29 is pushed up to a position where it is at a right angle to the panel portion 22rc or at an angle exceeding this.

The break progresses to the position of the end 26 of the score line 25 and ends f. At this time, the break 11 section 23 is MIIi with a score line of 25.
124.26 - is 9.26 at an angle of 30 to 90 degrees to the nozzle part 22 with the leapfrog as the hinge part. It is in a state of being suspended from the panel section, so to speak, and by pressing down on the end section 28,
Even if 9 is returned to its original position, 411IIIFT section 23&X
Since the panel 1s22 is still hanging inside the can body, the tab 29JP holder 23 does not get in the way when the consumer drinks the liquid from the can directly, and the 1io It has the advantage that there is almost no risk of injury to the operator's or drinker's fingers, etc., both during operation and when drinking.

However, this can 1121. In order to make it possible to return the tab 29 to its original position with the break 112m suspended from the panel s22 after breaking the score line 25f), the tab 2s and the matching part 31 of the panel s22 are connected. i [# part 2
Set on the outer side of 3, and score only by the pressing force in front of tab 29 @ @ 27! 125, so tab 2
The front end 27 of 9 cannot be brought close to the score line 25 that will break first (the score line 25 near the bond 1131).

Therefore, it is necessary to break the score 17125 and use a fairly strong force to open the can, making it difficult for women and girls to open the can, and making it able to withstand strong pressing force.

It is necessary to use thick tab material.

Furthermore, as mentioned above, the 1IIWR section 23 of *l121 is suspended inside the can body (inside the can body) after RO.
Because of this, when 1B packaging is transported or displayed, it may accumulate on the ground or accumulate on the ground. Dropped gourds and dust may fall into the moat inside a can (when the can is opened, etc.) or be washed away by the moat inside the can (when the hanging can wtS comes into contact with the wave inside the can). Regardless of whether you drink the 1F liquid in a can directly or transfer it to a can or cup, etc.

Consumers end up drinking 1IIIFT, K11, and dust, which poses a problem from a microbiological point of view.

This product @ is a tab non-separable metal easy-o 17 that eliminates the above drawbacks and also retains the advantages of the above type of can basket.
A can lid is provided, according to which there is a circular panel part, an iIl cut part defined by a discontinuous score line with both ends of the armpit panel part, and a rear part for pushing up. In the metal easy-open can 1iK, a set of tabs has a tab with the front part fixed in the cough cutting part.
The tab has an elliptical or III-shaped shape as a whole, and is located from near the periphery to the center of the cough panel part, and the tab is attached to the long axis of the cough value section or The scissors 1 [111] near the intersection of the dividing line and the score line are fixed in the 111 part, and one end of the cough score line is also near the [tab fixed part, and the score line is fixed in the sales tab. A non-separable metal tab, characterized in that the end near the fixing head extends to the other end through a location close to the tab fixing part between the tab fixing part and the rear part. 17 can lids manufactured by Easy-O are obtained.

1. In the present invention, the term "approximately oval" refers to a shape similar to a chicken egg, with one longitudinal end having an arcuate portion with a large radius of curvature and the other end having an arcuate portion with a small radius of curvature.
It also includes score lines with less roundness on one side, as shown in figure 7, and cases in which both ends of the score line are separated by p, as in figure 9. Furthermore, in the present invention, the term "approximately elliptical" includes the case where the arc of the intersecting portion along the long axis has a radius of curvature smaller than that of the original ellipse.

Next, an embodiment of the present invention will be described with reference to one drawing.

Figure 2 is a plan view of an example of the can lid of the present invention, spear 31Q is a plan view showing a state in which the score line of this can lid is cut halfway, and Figure 4 is a plan view showing the state in which the score line of this can lid is cut halfway. Figure 5 is a partial plane view in which the ffl amount tab shown in Figure 2 is omitted.

141 in the figure. Meso non-separable aluminum Easy-Own can lid with a circular panel part 2° in the center and outside
nikara/tarsink s3. Further, on its outer periphery, there is a joint 4 for joining the can to the can by a well-known means such as seaming and joining. 5, and in order to partially open the panel section 2, it is a roughly oval-shaped discontinuous score line carved into the panel section 2 and having a length of 6° 7, and 8 is this score! i [section] surrounded by I5. As can be clearly seen from Figure 5, this (・) score line 5 shows the state in which the tab explained in the next step has been removed.
It is a continuous line except around 6.7 of the 911 part, and is curled outward in the approximately I-angle direction around 6°7 of both ends. This score 115 has only a short length from the back of the tab fixing part 11 to one end 7, but has a considerable length from the other end 6. 9, and score l near the intersection of the longitudinal bisector of break s8 and score 115.
In the area surrounded by the small arc drawn by i5.

Its front portion lO is a tab fixed with a rivet, and one end of the score line 50 s61! , and the other end s7 is located in front of and opposite to the front portion 10 of the tab 9, and the other end s7 is located in the negative side of the front portion 10 of the tab 9. In addition, in the previous part lO of the tab 9, there is a recess s12 to strengthen this part tm.
is provided.

Also, the rear portion 13 of the tab 9 is chimled so that TWAv can be easily inserted from below. Further, in the cut section 8, a C-shaped recess W (that is, protruding inward from one can) 14 is provided along the score line 5 for imparting lIl properties. In addition, there is a score line 5 near the chest edge of the panel (on the inside and outside of the broken part 80) to prevent the broken edges of the broken part from damaging the lips, etc.
A pin 17.17 is provided which projects upwardly.

To open the can lid in this example, first insert your finger under the rear part 13 of the tab 9,
v Push up. Tab t panel fjAzttcl'! When it is pushed down until it becomes a varus of about 60 degrees, the flange score m5 of the tab fixed part 11 (score of the part indicated by 1 in Figure 5! 1) is increased due to the action of the lever using the fulcrum as a fulcrum. MIlla+ of the medullated part at the ruptured and i[IFl score edge
Lifted up with Etape 9.

At this time, score edge 5 (shape part in figure 7s) is fixed at 1! Since it is close to IIK and is a small arc with a small one-rate cattle price, it is easy to am.

Next, grab the tab with finger 11 and index finger (finger II is touching the bottom of tab 9 1111I and II!)
, while pushing it up (without lifting it up) and twisting it clockwise, a shearing force acts on the IFr score aS that is adjacent to the part of the score that has already been NII, and the breakage of the score Is5 occurs. Get up and get ready!
As the twisting force continues to be applied to the tab 9, the curl gradually progresses in the direction of the arrow (b) in Figures 1 and 5.
It stops after reaching FfrQ (see Figure 5).

The i[ll1f of the score line 5 due to the torsional force is 1IIFr due to the shearing force, and the shape of the score II5 as a whole is a gentle oval shape of 1 m1it, and the part that is i[ll1lr due to the torsional force is RK From the exposed part (portion a of III, 75-), there is no extension toward the outer angle (the angle direction in Figure 2g, 1, 5).

Moreover, the part that lies on the ground towards the outer corner is a gentle cocoon 1iI
Since the tabs 9 are connected by K, the breakage of the score 115 by applying a twisting force to the tab 9 proceeds with a relatively small force.

At this time, almost all of the score iIS from behind the tab fixed part ll to the tIIA part 7 direction III has already been broken by the 1lIWR force caused by the previous tab pushing up.

Also, near the end 7, the circumference of the fixed sll is 9ρ・etc.!
Curl in a direction approximately perpendicular to the 50 direction (-curl)
(However, when breaking i by pushing up the tab, refer to Figure 5, IIQ! [Bending to a corner (If the rupture does not reach the point P, then i[Wk progresses to the KP point).In other words, the breaking force due to this twisting is The break in the score line of 1rK is only used,
This point is also the reason why ii* progresses with less force.

The curl point Q near the score line end s7 of this example is as follows:
A car with a score of 70 or the other with a score of around 6.
Since it is roughly the same as the direction of the score 1m5 on the m+ side, the curl-like score near the m part 6 is close to aI50 i! It breaks as the break progresses, but after the break progresses to end 7, the score iIC is completed and the curl IIWr near *lIg is in a direction approximately perpendicular to the direction of the 1IllT force at this time. However, no further failure will occur. Further, when the twisting force is continued to be applied to the tab, the tab will be attached to the narrow hinge zhong which is sandwiched between both ends 6 and 7 of the score 5, as shown in Figure 4, while the tab s8 is fixed at the fixed part 11. At 15, it is fixed (or connected) to the panel s2 and is folded back at the ridge 1 and turned inside out, and the tab 9 is attached to the panel ill! will not be separated from you.

At this time, the tab 9 and the broken part 8 are essentially turned over on the panel s2 outside the opening s16, as can be clearly seen in Fig. 4, so that they can be directly transferred into the can from the H1 can ρ. It does not get in the way when drinking liquid.

(There is almost no risk of damaging your lips or nose with the 11g edge of the lip, and even if 1,000 dust is collected on a part of the can, there is no chance of it falling into the contents of a can.) It is hygienic as there is no
Since it is not very long and extends completely across the panel section 2, there is no danger of injuring fingers when opening the opening.

The soil is the can of this invention.

*IIF+ with score Ii5 initially pushes the tab fixation s11 peripheral score line *IFrL by lever action by pushing up the tab.
.

Next, the shearing force caused by pushing up and twisting the tab is applied to the remaining score lines, and essentially one score line is sequentially 111
Since it is done in the form of rj, the score is low!
2, the force on spear 1 shown in the diagram is large
Therefore, there is an advantage that a thin tab material can be used and manufacturing costs can be reduced. In addition, since the break s8 extends from near the center of the panel 20 from point p to the center, the opening 16 formed after the score m value is broken pours out the liquid transferred inside the can and becomes an island.

Note that if the C-shaped recess 14 is provided in the part along the score l115 in *#*B, the rigidity of this part will be increased, and the torsional force applied to the tab 9 will cause the broken 1urr part 8
This has the effect of preventing bending.

If the torsional force does not bend the fractured part 8, the force applied to the tab will efficiently work as a shearing force for score ii*, and therefore the force required for 10K11j will be even less. . - It is not necessary to provide '+R' in the case where the force expended on Ichiro is reduced by making the A section 8 smaller or the remaining plate thickness of the score section thinner in the case shown in 1111. but.

From the viewpoint of reducing the force that contributes to opening, it is preferable to provide this.

This rigidity is being added! R is a C-shaped 291 as shown in Figures 1-2 to 5, if the purpose can be achieved.
114, if fI, the tab sticks 1 as shown in Figure 16.
111 and the bottom part 111 of the front part 10 of the tab 9 is excluded.

As shown in the off-line diagram, the score is 1 is KB, and the part that is distorted by the arc that is about the length of a cow and the string that connects both ends of this arc is concave, and there are multiple parallel concavities as shown by the arrow 8. In addition to the grooves and 7, it may have any shape, such as multiple radial grooves extending from the center of the iI exposed 11s to the outer part, a combination of two or more grooves extending in different directions, or an annular depression. Can be done. In addition, in order to connect the purpose, the rigidity imparting means only needs to be Wl from 5 seconds of the score line breaking W# due to the twisting force to approximately a cow's worth of 11 WR.

*-The sex imparting hand R may be a convex part or convex strip of the same shape instead of the concave part or concave strip of the above-mentioned shape, but the opening operator or the can directly transfer liquid from the can to the can. the fingers of the person who drinks, m,
From the viewpoint of protecting the nose, etc. from the sharp broken part of the cut part 8 (injury prevention), a recessed part or grooved strip is preferable.

In addition, if the tab is completely turned over after the tracing movement has been completed, but the broken part 8 is not completely turned over yet, you can press down the broken part 8 with your finger. It does not get in the way when drinking the contents of the can directly from the can, and there is less risk of damaging the aiIF nose, etc. Further, if the rigidity imparting means in the portion of the broken wt portion 8 close to the score line is a convex portion, a grooved groove, or the like.

When 1ILIIFrs8 is turned upside down, it becomes a convex part or protruding strip, which prevents the broken part from coming into contact with fingers, lips, nose, etc., so it can be used when pushing down with fingers or when drinking the liquid inside a can. Consumers are no longer at risk of injury.

Next, another example is a@ with jF6B (1,000 II figure).

The main point that this differs from the above-mentioned implementation model (Figs. 2 to 5) is that a shallowly carved non-4I [score border of the section] is provided on the outer part of the score line 5, and it is a gender imparting means. Recess 1
4 is the shape of the tab fixing part 11 and the front part 10 of the tab 9.
Substantially the entire oval-shaped broken part 8 except for the part that becomes 0-lower is recessed and horizontally circular, and the front part 10 of the tab 9
The shape of.

In the above example, ? There are three recesses l112 for the 11-strong type, and while the rivet hole is in the central flat recess 12, one has a bowl-shaped recess 18 on the edge of the rivet hole.

It has two concave lines ls and is (both for the tab ring part) facing this concave 161g and extending substantially perpendicularly to each other.

Score 815 KE for 1IIFr! By providing a score of 1Iif/ for non-a cutting, it is possible to improve the ease of manufacture and opening property by widening the criteria for embedding the tube, such as the depth of the groove for score 5 for I[. The front part of the fixed part 11 and the tab 9] By recessing the entire part of the broken part 8 except for the lower part of 0, the score is made into a double score, and this makes the score better than that of the embodiment shown in Figures 72-5. It can also be opened quite easily. Furthermore, the ring around the rivet hole! ! l1ii
1B and the two grooves 19, 19 around it are the example of m! ! Similarly to Part 1 17, when the score line 5 is i[W#, 8v serves to prevent the tab from deforming.

The opening operation of the spear 6 shown in Figures @iil is exactly the same as in the embodiment shown in Figures 2 to 5 for 1 year, and briefly, insert your finger into the lower part of the rear part ls of the tab 9 and push it up.

Break the score line 5 around the stuck m1ll, and then grab the tab 9 that still has an inclination of about 5♂ to 7♂ with respect to the panel SZ, push it up slightly and turn it clockwise to remove the remaining score line 5. It gradually breaks from the tab fixing part 11 toward the end 11116, and after the score line 5 is broken, the tab 9
The broken part 8) can be turned over onto the tunnel 2.

This can 111 also has tabs 9 and 111TI turned inside out.
#aS is connected to the panel part 2 between both ends 6.7 of the score sheet 50, and this part is a hinge part.
The 16 foreign panels are folded into the 2nd earth, so =*
*It prevents the SS tab 9 from scattering, does not get in the way when drinking the liquid directly from the can, and is 1ItFr.
Coupled with the presence of the bead 17 and recess 14 close to 1111, there is almost no risk of injury to the drinker due to heat or nose pressure, and furthermore, the gourds and dust accumulated in the broken part 8 of the can can fall and the contents. It is hygienic as there is no risk of soil being washed off and mixed in, and the force required to open the opening is small, so even women and girls can open the opening, and there is almost no risk of injuring fingers, etc. % has the same effect.

The score S residual thickness of the right 11 part of lFr1iB (see Figures 2 to 11) is made thinner (the board thickness after the score is carved) (then the force applied to the opening is reduced, so a rigidity imparting means is also used) Even if V is not provided, it can be opened easily.In order to make the score S thinner than the remaining thickness, it is recommended to use a tuple score edge as shown in the example of 1 year old and 6 years old.

*WIS, or reduce the distance between both ends of the score line.
By widening I as in the example in figure 9, or by selecting conditions such as the direction of the score line at the part where the 41L break stops, you can ensure that the i[lFr1B is turned into a KJI turnout to 11 outside the counter tank part! ! ! You can prevent it from coming out.

It is preferable to do this from the viewpoint of preventing serious injury to the collecting staff when collecting the cans 4.

In addition, in the embodiment described above, the fracture part 8 closest to the periphery of the panel part may be a part with a relatively small medium diameter of curvature (in this case, 4[*lI8 and tab 9 The same part of the panel will also be moved to the periphery of panel s2.

In the can lid/work of the present invention, as described above, after performing the score IFrY around the tab fixation S using the lever action of pushing up the tab,
Since the remaining score line is cut by the shearing force caused by the twisting force of pushing up the tab, it can be opened with relatively little force, and there is no need to use a particularly thick tab material. The broken part is approximately oval or 1111!R circular, so there is no risk of hurting your fingers when opening the opening.
Furthermore, the broken W#S fixed to the tab is turned over onto the panel part with a portion thereof fixed to the panel part.

It is hygienic as there is no risk of dirt or dust accumulated on the outer surface of the can getting into the contents of the can, and the tab with the iIW# part of the can whose contents have been consumed will not be scattered in the consumption area etc. In addition, since the i[llFr1l is located near the first side of the panel 5jii to the central part, the contents of the can can be easily spilled out, and in addition, the liquid inside the can can be easily removed from the can when drinking or drinking. 1 effect that there is almost no risk of hurting! do.
