Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an easy-opening can lid that has a prize tip with a mark that can be exchanged for prizes or prizes used by canned drinks selling companies to promote the sales of canned goods.

[0002]

[Prior Art]

 Easy opening of canned beverages.Scores and figures are printed on the ruptured part of the can lid, and a certain number or more of the number of points and figures printed on the ruptured part are collected and sent to the beverage canning sales company. Commercial methods are often used to promote the sale of canned beverages in which the prize money and prizes are exchanged for prizes or prizes are given to the winners.

A conventional easy-opening can lid 100 for a beverage as shown in FIG. 6 (A) is a platter fixed in a breaking portion 104 surrounded by continuous score lines 101. 102 to rupture the score line 101 around the fixed portion 103, and then pull up the pull tab 102 to rupture the remaining score line 101, and the rupture portion 104 is separated from the lid plate 105 together with the pull tab 102. The consumer can collect a fixed number of the broken portions 104 as shown in FIG. 6 (B) on which the scores and figures are printed and mail them to the beverage can sales company.

However, if the breaking portion with the pull tab is separated from the lid plate and is thrown to a place other than the trash can, it is difficult to clean, and the breaking portion may cause an unexpected injury. Also, an easily opened can lid of a type in which the tab is not separated from the lid plate, in particular, an easily opened can lid called "Steion tab" disclosed in Japanese Patent Publication No. 57-42544 has begun to be widely adopted.

This easy-to-open can lid has a break portion surrounded by a score line (a score line having a start end and an end end separated from each other) having a discontinuous portion on the cover plate, and on the break portion. It is located near the front end with the front end placed, and most of it, including the rear end, placed on the lid plate outside the break, and is surrounded by a C-shaped cut line that is open on the front end side. The attachment part has a tab fixed to the lid plate at a position close to the score line outside the fractured part.

This easy-to-open can lid further causes the score line between the front end of the tab and the attachment to break first when the consumer puts his or her finger under the rear end of the tab to cause the rear end. And the remaining score line breaks, and the broken part hangs down from the lid plate into the can with the discontinuity of the score line as the hinge part.

After that, even when the tab is returned to its original position, the fractured part remains hung and the tab remains fixed to the lid plate at the attachment part. Therefore, when the can is discarded after the can contents have been consumed, the breaks and tabs do not scatter away from the can.

[0008]

[Problems to be solved by the device]

 However, since the breakage part of the easy-open can lid called the Stein tab does not separate from the lid plate, the beverage can sales company can print the score etc. on the breakage part as in the past, and keep the fixed number of points. The sales promotion law of giving prizes to the collected consumers is no longer valid.

[0009] Because empty cans are very bulky, it is expensive to collect some of them and send them to the sales company, and the sales company also needs to make the space for the empty cans very large. This is because it is not suitable for cost.

It is an object of the present invention to provide an easy-to-open can lid that can carry out a sales promotion method as in the past even in the case of the easy-to-open can lid whose breakage part and tab are not separated from the lid plate. And

[0011]

In order to achieve the above object, in the easy opening can lid of the present invention, a scoring line having a discontinuous portion is engraved to form a broken portion in a part of the lid plate. The tab consisting of the holding part at the front end, the lifting part at the rear end, and the intermediate mounting part places the holding part on the breaking part and places the lifting part on the lid plate outside the breaking part. In the easy-open can lid of the type in which the mounting portion is fixed to the lid plate outside the breaking portion and the breaking portion and the tab are not separated from the lid plate in the mounted state, the tab is A central hole portion having an inner peripheral curl portion between the mounting portion and the lifting portion, and a position between the central hole portion and the mounting portion, the tip of which is close to the upper surface of the lid plate, or For a prize with a marked mounting hole, with a connecting part with a protruding protrusion to abut -Up has been the mounting hole to the configuration provided by fixedly fitted on the projecting portion. It is preferable that this easy opening can lid is formed so as to penetrate through the attachment hole of the prize chip, and the tip of the protruding portion of the tab is extended larger than the attachment hole of the prize chip. The mark on the prize chip is made up of one or more of symbols, letters, numbers, figures, patterns, or one or more of concaves and convexes with ink or paint. It can be a symbol, a letter, a number, or a figure consisting of one or more.

[0012]

[Action]

 Prior to opening the lid plate, the prize chip with attachment holes has its attachment holes fitted and fixed to the protrusions provided on the connecting portions of the tabs, and the tabs have the tips of the protrusions on the top face of the lid plate. Since the prize chips are mounted close to each other or in contact with each other, the prize chip will not be taken out from the central hole without being removed or dropped during transportation.

When opening the cover plate, put a finger under the lifting portion at the rear end of the tab and raise the lifting portion. Then, due to the lever action, the score line is broken, and the broken portion hangs down from the lid plate into the can with the discontinuous portion of the score line serving as a hinge portion. After that, even if the tab in a substantially vertical state is returned to its original position, the fractured part remains hung and the tab remains fixed to the lid plate at the attachment part.

Then, the tab is in a substantially vertical state from the time when the tab is opened and the tab is returned to the original position while the tab is not cut off from the lid plate. There is no obstruction on the tip side of the protruding part, and since the inner edge of the central hole is curled, even if you press it strongly with the finger from the curl surface side, you will not hurt your finger. It is possible to displace it so much that only the prize tip can be pulled out from the tip of the protrusion.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. (Structure) FIG. 1 is a plan view showing an easy opening can lid of the embodiment, and FIG. 2 is a sectional view taken along line II-II of FIG.

The easy opening can lid A is composed of a lid plate 1 wound around an opening portion of an upper surface of a can body (not shown) and a tab 2 fixed to the lid plate 1.

The cover plate 1 has a fractured portion 11 surrounded by a score line 10 having a discontinuous portion 15 having a start end and a termination end spaced apart from each other, and a reinforcing bead 12 for reinforcing the fractured portion 11. A fixing rivet 13 formed at a substantially central position of the lid plate 1 for fixing the hook 2 and a finger insertion concave portion 14 formed at a position opposite to the breaking portion 11 with the fixing rivet 13 interposed therebetween are provided. There is.

The score line 10 is a double score line consisting of an inner score line and an outer score line. Of these, the depth of the outer score line is deeply engraved, and this part is broken when opened. It is supposed to be done.

The tab 2 has an outer peripheral curl portion 20 on the outer periphery and is composed of a front end pressing portion 21, a rear end lifting portion 22 and an intermediate mounting portion 23. The pressing portion 21 is placed on the breaking portion 11. It is fixed to the fixing rivet 13 of the lid plate 1 at the mounting portion 23 in a state where it is placed and most of the portion including the lifting portion 22 is placed on the lid plate 1 outside the breaking portion 11. The mounting portion 23 is arranged near the pressing portion 21 of the tab at a position close to the outer score line 10 of the breaking portion 11, and the pressing portion 21 side is opened by a C-shaped cut line 24. being surrounded.

Further, the tab 2 includes a central hole portion 26 surrounded by an inner peripheral curl portion 25 that is bent between the lifting portion 22 and the mounting portion 23, and the central hole portion 26 and the mounting portion 23. A connecting portion 31 having a protruding portion 30 whose tip is in contact with the upper surface of the cover plate 1 is provided at a position in the vicinity of the center. Then, between the tab 2 and the upper surface of the cover plate 1, it extends from the mounting portion 23 side to the lower end of the inner curl portion 25 of the lifting portion 22, and a mark (a star-shaped figure in the figure) 27 is formed. A prize tip 29 with a mounting hole 29a made of resin (made of polypropylene in this example) that is easily formed by extrusion molding is provided by fitting and fixing the mounting hole 29a to the protrusion 30.

The tab 2 is such that the tip of the protruding portion 30 to which the prize chip 29 is fitted and fixed is caulked and brought into contact with the upper surface of the lid plate 1, and the lower surface of the outer peripheral curl portion 20 is placed on the lid plate 1. It is firmly attached to the cover plate 1 so as to be closely attached to. In this way, unless the consumer puts his / her finger under the lifting portion 22 of the tab 2 and raises the rear end vertically, the prize tip 29 fixed to the protruding portion 30 of the tab 2 cannot be removed. is there.

When eating or using the contents of the can having the easy-open can lid A, when the lid plate 1 is opened, the consumer puts his / her finger under the lifting portion 22 of the tab 2 to set the rear end. When raised, the score line 10 between the holding portion 21 and the mounting portion 23 of the tab 2 breaks first due to the lever action with the holding portion 21 of the tab 2 as a fulcrum and the vicinity of the mounting portion 23 as the point of action. .. After that, the remaining score line 10 is broken by the lever action with the pressing portion 21 as the point of action with the vicinity of the mounting portion 23 of the tab 2 as a fulcrum, and the pressing force from the pressing portion 21 continues to act on the breaking portion 11. The breaking portion 11 hangs down from the lid plate 1 into the can using the discontinuous portion 15 of the score line 10 as a hinge portion.

After removing the prize chip 29 from the tab 2 (removal operation will be described later), even if the tab 2 which is in a substantially vertical state is returned to its original position, the broken portion 11 still hangs down. The tab 2 is still fixed to the cover plate 1 by the fixing rivet 13 at the mounting portion 23.

(Removing operation of prize chip 29) As shown in FIG. 3, when the tab 2 is raised up to be almost vertical to the lid plate 1 for opening, the prize chip 29 is fixed. Since there is no obstacle on the tip side of the protruding portion 30 and the inner edge of the central hole portion 26 is curled on the inner circumference and there is no sharp edge around it, a prize is awarded from the inner peripheral curl portion 25 side of the central hole portion 26. A strong pressing force can be applied to the surface of the tip 29 for displacement, and the tip 29 for competition can be easily pushed out and removed from the protrusion 30 by making a large displacement. Then, the required number of prize chips 29 can be attached to an application form or the like with a tape or the like, and sent to a sales company or the like by mail.

(Manufacturing Method) The easy-open can lid A of the embodiment is manufactured by using the following method, for example. The tab 2 is formed by a curl forming step of edging the central hole portion 26 and its peripheral edge in a transfer press step as disclosed in, for example, JP-A-60-23145 or JP-B-64-9227. It is manufactured by incorporating the protrusion 30 molding process.

The resin-made prize tip 29 which can be easily removed by extrusion is separately manufactured by injection molding or compression molding separately from the manufacture of the tab 2, or is pressed on the resin sheet after extrusion molding. It can be manufactured continuously or by injection molding to form a very long molded product by connecting the front and back with a fine chain.

After the tab 2 and the prize chip 29 with the attachment hole 29a are manufactured, the tab 2 and the prize chip 29 are combined to make the tab 2 with the prize chip 29 in advance. As a combination method, for example, a product manufactured on a resin sheet is, for example, continuously cutting the prize chip 29 from the resin sheet in the transfer press process of the tab, while the prize hole 29a of the prize chip 29 is attached. A method of inserting and fixing the protruding portion 30 of the tab 2 can be adopted. In order to ensure that the tab 2 of the prize tip 29 is fixed to the protrusion 30, the diameter of the attachment hole 29a of the prize tip 29 is made larger by pressing the tip of the protrusion 30 or the like. Crimp to.

After that, the tab 2 with the prize chip 29 is fixed to the fixing rivet 13 of the cover plate 1 at the mounting portion 23.

When the marks 27 are formed on the prize chip 29 by molding concave portions or convex parts, or by printing or painting, the prize chip 29 can be molded (for example, by injection molding, press molding, extrusion molding). A concave portion or a convex portion is formed, or before or after the prize chip 29 is combined with the tab 2, or after the tab 2 combined with the prize chip 29 is fixed to the cover plate 1 by a jet printer.

As described above, in the easily opened can lid A of the embodiment, the following effects are obtained.

(A) A protrusion 30 formed on the upper surface side of the lid plate 1 of the connecting portion 31 of the tab 2 and having a mark 27 extending from the mounting portion 23 side toward the lifting portion 22 side for easy extrusion removal. Since the breakable portion 11 and the tab 2 are the easy-open can lid A of the type in which the breakable portion 11 and the tab 2 are not separated from the lid plate 1, only the prize tip 29 with the mark 27 is provided with the protruding portion 30. It can be extruded from the product to win prizes and apply to sales companies. That is, when the cans are discarded after the contents of the cans are consumed, the breakage portion 11 and the tabs 2 do not scatter apart from the cans without impairing the usefulness of the Steion tub, and the beverage can sales company. The sales promotion method of giving a prize to a consumer who has collected a certain number or more of the marks 27 on the can lid A can be carried out as usual.

(B) When the prize tip 29 is largely displaced with a finger or the like and pushed out and removed from the protruding portion 30, the inner peripheral curl portion 25 is formed at the inner edge of the central hole portion 26 on the pressing surface side, which is sharp. Since there is no cut portion, even if a strong pressing force is applied to the prize tip 29, the finger is not injured at the periphery thereof.

C) The tab 2 is closely attached to the lid plate 1 with the tip of the protruding portion 30 to which the prize chip 29 is fitted and fixed is brought into contact with the upper surface of the lid plate 1, and is attached to the lid plate 1. Fixed. Therefore, the prize chip 29 will not be illicitly removed during the store display, and will not fall off from the protruding portion 30 during transportation or transportation.

D) Furthermore, the prize chip 29 can be provided by a simple attachment means that is fixed to the protrusion 30, and can be manufactured in a large amount by a simple molding means such as injection molding. As a result, the production cost is not too high.

Although the embodiment of the present invention has been described above with reference to the drawings, the specific configuration is not limited to this embodiment. For example, the mark given to the prize chip 29 is not limited to the uneven shape at the time of molding, but may be ink or paint, or a combination of two or more thereof. In the case of the ink or paint mark, , A symbol, a character, a numeral, a figure, or a pattern. In the case of a mark having a concave portion or a convex portion, it may be one or more of a symbol, a character, a numeral, or a figure. In addition to the polypropylene of this example, vinyl chloride, nylon, polyethylene, etc. can be used as the material of the resin prize tip 29, and the heat-resistant resin is used for the can lid for the retort can that is sterilized at 100 ° C or higher. To use.

Further, in the present example, the shape of the prize chip 29 is a substantially triangular shape so that the prize mark 27 can be made large, but the shape is not limited to this, and when the mark is small, it is possible. May be smaller than this, and is appropriately determined according to the shape of the central hole portion 26 and the manner of applying the mark.

Further, in the tab 2, the tip end of the protrusion 30 to which the prize chip 29 is fitted and fixed is brought into contact with the upper surface of the lid plate 1, but the prize chip 29 is displayed during the store display. The tip of the protruding portion 30 may be brought close to the upper surface of the cover plate 1 if it can be prevented from being illegally removed or dropped during transportation or transportation. In addition, as shown in FIG. 2, the shape of the tip of the protruding portion is such that the hole does not penetrate, and as shown in FIG. good. Further, as shown in FIG. 5, a bottomed mounting hole 29b into which the tip of the protruding portion 30 can be inserted is provided in the prize tip 29 without the protruding portion 30 completely penetrating the prize tip 29, so that unevenness is formed. The same effect can be obtained by fitting and fixing.
