Description

The present invention relates to a pull tab such as a beverage can, a method for manufacturing the pull tab, and a method for using the pull tab.

In the past, the history of can development was that cans that can be opened with can openers, and then cans with pull tabs that do not require can openers were sold along with the appearance of aluminum cans. Due to the accident of infants due to the separation of the pull tab from the can lid and the effects on animals, the can was developed in which the pull tab was not separated from the can lid. These are the history of the development of convenient and convenient cans.

In recent years, in order to promote sales of canned beverages, sales promotion measures have been taken to receive benefits by attaching stickers for application for prizes to the can body and collecting and mailing them.

In addition, there is a method of use as a sales promotion measure in which an Internet URL or can identification number is written on a sticker, which is input and transmitted to a portable terminal or a computer, and then communicated to be linked to sales promotion.

Further progress has been made in an example in which a sticker described in a two-dimensional code that does not require the input of a URL is pasted on the side of the can and used for sales promotion planning.

Further, the construction of a system capable of exchanging information between the purchaser's mobile terminal and the beverage manufacturer's server is required as a customer containment strategy.

Two-dimensional code has begun to be recognized as one of the important materials and technologies of the above sales promotion strategy.

Two-dimensional codes are an important technical element when creating a system in which information can be exchanged mutually by connecting a purchaser, a purchased item, and a manufacturer's server via the Internet easily and inexpensively.

The function provided by the two-dimensional code can also be considered as an information exchange function for easily connecting the purchaser's mobile terminal and the beverage manufacturer's server.

In addition, the element technology provides not a “simple information exchange function” but a mobile phone that records the operation of connecting to the server based on the result of reading the two-dimensional code. It is to develop various services for telephones.

By recording the right to receive these services in a database and building a system that can access the data through the network, it is possible to use the two-dimensional code as a tool for transferring rights. You can also.

For this purpose, the unused (undisclosed) information (including identification number) of other unsold products is inferred from the used information (including identification number) encoded in the two-dimensional code. Must not.

For this purpose, it is necessary to encrypt the identification number encoded in the two-dimensional code or to make the two-dimensional code invisible. However, redundancy of information encoded by encryption increases.

If security management including encryption is applied to the two-dimensional code, the can becomes the proof and key of the access history, and the can of the present invention is based on the result of the mobile phone reading the two-dimensional code as a can with fraud prevention function. It is possible to record operations for connecting to a server and provide various services for mobile phones.

By recording the right to receive these services in a database or the like and building a system that can access the data through the network, it can be considered that the two-dimensional code can serve as a storefront or a contract.

For example, in the case of a sales promotion plan, the mobile phone can be used as a tool for automatic personal authentication by recording the connection to the server based on the result of reading the two-dimensional code. It is possible to develop a reliable credit service.

Customers can be locked in by managing the right to receive these services for a long period of time. Customer service that has never existed before can be constructed.

The function given to the two-dimensional code is that the consumer can read and transmit the two-dimensional code according to the information encoded in the two-dimensional code and the usage conditions, the program set in the server, and the conditions set in the program. If it was devised as a bonus, a lottery ticket, a voucher, a point service ticket, a service exchange ticket according to the number of times it was used Even if devised in, all of these can be thought of as a right exchange function associated with the provision of a right and the acceptance or use of that right.

In other words, pulling up the pull tab and opening the can and reading the two-dimensional code written on the printing field is different in name, changing the shape, the manufacturer entrusts the canned beverage of each one unit, the above to the consumer Content that can be exercised at the time of renewal by reading the two-dimensional code with the mobile terminal and communicating with the server database based on the information encoded in the two-dimensional code. It can be thought that there is a meaning similar to clarifying rights using a contract at the store.

Therefore, in a system that uses a two-dimensional code, the availability of the two-dimensional code is verified, the validity is confirmed, the duplicate use is eliminated, the access is restricted (including the number of times), and the access form is restricted. Similarly, the portable terminal to be read performs confirmation of the validity of the portable terminal including identification of the user of the portable terminal, elimination of redundant use, restriction of access (including restriction of the number of times), and restriction of the form of access.

Furthermore, it becomes necessary to associate and manage the identification number encoded in the two-dimensional code and the information managed by the server such as the identification number of the portable terminal.

This is an act of the same purpose as the management of transaction requirements in normal business practice. Therefore, first of all, it must be possible to prevent unauthorized use of the two-dimensional code.

Otherwise, the credibility of the manufacturer adopting the two-dimensional code in the sales promotion plan is damaged, and not only the sales promotion effect is halved but also the original business and credit are hindered, resulting in consumer distrust.

In other words, the necessary conditions regarding the two-dimensional code that should be provided in the system using the two-dimensional code are 1) provided with an unauthorized use prevention function that only the purchaser can access.
2) The 2D code can only be accessed after purchase.
3) Easy to read and use.
4) The cost of using it is low.
5) It is necessary to grasp the user's rights and to have a function for restricting it, such as verification of availability, confirmation of validity, elimination of duplicate use and access restriction.

When displaying a two-dimensional code on a beverage can as a product, it is generally known that the label is attached to the can body.

However, the can beverage with the two-dimensional code attached to the can barrel can be read by peeling off the label attached to the can barrel without purchase, and there is a problem in preventing unauthorized use. Also lost,
There were also problems that could not be read correctly during the campaign period due to damage, contamination, deformation, deterioration of the material that clearly indicated the 2D code, and so on.

As is well known, various types of questionnaire systems are known in which a two-dimensional code is attached to a beverage can or the like and the purchaser's reaction after purchase is collected.

For example, Japanese Utility Model Laid-Open No. 5-94121 relates to a pull tab for applying for a campaign. However, it is said that at least a part of the separation piece portion is located below the finger-hanging portion, but this cannot be implemented in an economically reasonable manner.

Japanese Patent Application Laid-Open No. 2004-309885 is known as an invention for the purpose of preventing a person who does not purchase a product from reading a two-dimensional code. However, there is a defect that the label can be removed without opening the can. The present invention causes an irreversible change in the shape of an article, and a structure in which a two-dimensional code can be read only after an overflow of contents and a can opening action with sound such as “push” or “kappa” It has become. For example, fraud is prevented by not being able to read a two-dimensional code by stealing a store clerk's ear.

Japanese Patent Application Laid-Open No. 2006-58767 describes a label in which two layers of base materials are detachably laminated, an upper layer base material is peeled off, and a two-dimensional code on a lower layer base material surface is read by a mobile phone.
In the above invention, a label is attached to the can body. It is easy to peel off the upper layer base material, and it is also easy to peel off the entire lower layer base material. There is a defect that even a non-purchaser can read a two-dimensional code.

Japanese Patent Application Laid-Open No. 2006-268863 discloses a questionnaire system based on information communication between a mobile phone and a server via a two-dimensional code. However, there is no mention of collecting evaluations immediately after drinking for each single item such as a can beverage.

Japanese Utility Model Laid-Open No. 5-40132 describes an example in which a promotion tool is attached to the back side of a pull tab. However, there is no mention that a two-dimensional code is printed with a laser marker and fixed or integrated to realize an anti-theft mechanism, and a real-time questionnaire survey is conducted to the purchaser via the two-dimensional code. Is not mentioned.

In the following paragraphs, “pictures and characters” will be described as “two-dimensional code”.

According to the present invention, the following excellent effects are exhibited. None of these were possible with the prior art.

The advantages brought about by displaying the two-dimensional code on the back of the pull tab shown in FIG. 1 are effective in 1) prevention of unauthorized use.
2) It can only be read after opening the can.
3) It is configured to perform an operation of reading after drinking.
4) The configuration that is read after drinking matches the human behavior.
5) The two-dimensional code can be freely concealed and disclosed in accordance with the drinking timing.
6) When configured as described above, resource saving, energy saving, and recycling performance were improved.

It consists of pull tab, printing field, 2D code, laser marker and management code,
1) When attaching a label that can conceal and expose the 2D code to the can body,
In contrast to the method of installing a two-dimensional code on the upper surface of the can lid and concealing it with a pull tab, the two-dimensional code is installed in a printing field fixed to the pull tab or integrally formed.
2) If you start the action of putting your finger under the pull tab and starting it, the pulling angle is about 15 degrees, and the can lid 9 starts to tear along the score line. At the same time, the sound such as “push” or “kappa” To emit.
3) When moving around 15 degrees or more at the same time, the container undergoes an irreversible shape change, and the contents overflow accordingly.
4) However, at this angle, the two-dimensional code 2 cannot be read by the portable terminal 5.
5) Since non-purchasers cannot prevent sound, it is now possible to reliably prevent unauthorized acts of reading only a two-dimensional code in the store.
6) Even if an attempt is made to read a two-dimensional code illegally and an attempt is made to read by turning the pull tab with the rivet as the center of rotation, the torque required for the original opening operation of the pull tab is impaired and the can cannot be opened. Without opening the can, the 2D code will not be exposed and cannot be read. This is an effect that the printing field of the present invention is fixed to the pull tab or formed integrally.
7) With the pull tab according to the present invention, the two-dimensional code cannot be read by anyone other than the purchaser.
8) Since the purchaser can read the two-dimensional code without opening the can, it is now possible to collect questionnaires of the purchaser's evaluation immediately after the purchaser has surely opened and taken the drink.
9) Since the printing field and the pull tab are fixed or integrally formed and the printing field is installed on the back of the pull tab, the printing field is not visible to the purchaser and, naturally, the two-dimensional code is not visible to the purchaser. . Even if it can be seen, it cannot be read on a mobile device.
10) As a result of having a structure that cannot be read smoothly unless at least the pull tab is pulled up by 100 degrees or more, the display of the two-dimensional code is after opening the can.
11) The two-dimensional code of the present invention does not appear so that the whole image can be read smoothly unless the pull tab is raised to about 110 degrees after the can is opened and drinking is completed. Even buyers don't understand.
12) Before purchase, it is not noticed that a foreign object is displayed at a position (can lid) where the purchaser touches the mouth.
13) Therefore, there is an effect that does not give a sense of incongruity. (Don't watch until you finish drinking.)
14) Having a sense of incongruity is not a good idea in terms of sales promotion. This is an important response from customers.
15) If the rivet is forcibly swung to read, the can opening function is lost as an original pull tab, and the can cannot be opened even if the swivel is restored.
16) By using the same material for the printing field and the pull tab, the material utilization efficiency is improved, resources can be used effectively, recycling efficiency is improved, and production costs are reduced.
17) As a result of printing with a laser marker, it was possible to print directly on the metal that is the sheet metal material of the pull tab.
18) Since the sheet metal material is integrally formed, the laser marker can be used for printing, and the concealed two-dimensional code and the always-disclosed management code can be simultaneously printed on the same sheet metal material.
19) As a result, it has become possible to guarantee equivalence to the data that is always visible (external data) that can be seen after the opening operation (internal data).
20) Since the internal data and the external data (management code) can be used in the same value, it has become possible to perform single item management required as a manufacturer.

Furthermore, the effect of the invention of another object is that it is composed of a printing field, a two-dimensional code, a laser marker, a pull tab and a seal, and when the pull tab is pulled up and opened, the sales promotion utilizing the information clearly shown on the first visible seal Participate in the project first, and then re-participate in a sales promotion plan that uses a two-dimensional code that is exposed after the seal is peeled off. Multiple projects with time differences can be done. This mechanism has made it possible to implement more complex and highly effective sales plans at a low cost.

Further, the effect of the method of use as an invention is that the printing field, the two-dimensional code, the laser marker, the pull tab, and the seal are constituted, and the identification number of the two-dimensional code encoded in the two-dimensional code is a continuous missing number from N to M. By setting the unit LOT configured with the identification number to a non-natural number, the setting of the access to the remaining cans of the same LOT and the limit on the response time limit from the time when the first unit LOT is opened and the server is accessed I was able to. By using such an identification number of a numerical sequence, it becomes possible to operate the restriction on the answer end time from the first answer start time in LOT units.

Further, the effect of the manufacturing method is that the printing field, the two-dimensional code, the laser marker, the pull tab, the first mold part, the second molding part, or the printing field, the two-dimensional code, the laser marker, the pull tab, the seal, and the first. It consists of a mold part and a second mold part,
1) According to the pull tab according to the present invention, the manufacturing and assembly process of the three types of components that constitute the beverage can, that is, the can body, the can lid, and the pull tab, and the development, update, and change of new equipment are minimized. There is an effect to suppress to the limit.
2) In the case of the present invention, the beverage manufacturer does not need to recombine the assembly process of the three types of components, the can body, the can lid, and the pull tab, in the existing factory equipment.
3) In the case of the present invention, the can manufacturer does not need to update, change, or recombine processes in the existing factory equipment to the production line of two types of components, the can body and the can lid.
4) In the case of the present invention, the can manufacturer does not need to update, change, or recombine the process to the can lid main body line except the pull tab in the existing factory equipment.
5) In the case of the present invention, the can manufacturer can renew, change, and recombine the equipment in the process of combining the pull tab with the can lid body in the existing factory equipment, but this can be suppressed as the minimum necessary change. effective.
6) In the case of the present invention, there is an effect that the can maker only has to concentrate on the development of only the machine that makes the pull tab.
7) By using the same material for the printing field and pull tab, compared to the case where a two-dimensional code is displayed on a label, etc., the can manufacturer does not need to separate waste materials in the factory and does not need to be separated in the market. It becomes. By using the present invention, there is an effect that effective use of resources and recycling performance are improved. There is no need to transport labels.
8) It becomes possible to collectively purchase materials, and there is an effect of reducing the cost of purchasing materials.
9) There is also an effect that the process is simplified by making the printing field the same material as the pull tab.

Furthermore, the effect of the present invention as another method of use is that a printing field, a two-dimensional code, a laser marker, a pull tab, a portable terminal, a server, or a printing field, a two-dimensional code, a laser marker, a pull tab, a seal, a portable terminal, and a server. And consists of
1) It is possible to reduce the difference between the time when the can drink was drunk and the time when the questionnaire was answered, and there is an effect that the evaluation information of the product at the time of drinking can be obtained.

The design, characters, etc. include 2D barcodes, 1D barcodes, 3D barcodes, and the like.

Sheet metal materials include aluminum coils, aluminum plates, tin plates, and iron plates.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Items common to a plurality of embodiments are described in the first embodiment and may be omitted later.

Proprietary nouns that are uniquely named and adopted verbs are defined at the beginning.

FIG. 1 is a perspective view of the outline of a beverage can in which an opening is opened, a two-dimensional code is printed on a printing field on the back side of the pull tab at a position facing the upper surface of the can lid, and the pull tab is raised to an angle that can be read by a mobile terminal. is there.

1, reference numeral 1 denotes a printing field, reference numeral 2 denotes a two-dimensional code, reference numeral 4 denotes a pull tab body, reference numeral 8 denotes a rivet, reference numeral 9 denotes a can lid body, and reference numeral 10 denotes a can body.

The printing field is fixed to the pull tab or is integrally formed, and the entire image of the two-dimensional code printed on the printing field is exposed and readable only when the can is opened by raising the pull tab.

FIG. 2 is a plan view of the can lid before being opened as shown in FIG.

FIG. 3 is a view in which the pull tab is folded back to just above the opening. It can be seen that the pull tab and the printing field are fixed or integrally formed. This state is inherently easy to read on a portable terminal.

FIG. 15 shows that even if the pull tab attempts to open by turning more than 90 degrees horizontally with the rivet as the center of rotation, the pull tab cannot correctly open the score line and cannot open the can.

The force required to break the score line is learned from the relationship of the three points (fulcrum, force point, action point) acting on the insulator: the point where the finger of the pull tab acts, the position of the rivet, and the point where the pull tab touches the opening. Therefore, the position of the point acting on the opening must be an appropriate position as intended as designed.

For this reason, the pull tab is elaborately calculated and attached.

If you open the can with excessive force, the pull tab will bend and you may not be able to open it even if you try to open it back to its original position.

FIG. 3 is a view in which the pull tab is folded back 180 degrees above the opening. It shows that the pull tab and the printing field are fixed or integrally formed. Reference numeral 1 is a printing field, reference numeral 2 is a two-dimensional code, reference numeral 4 is a pull tab body, reference numeral 7 is an opening, reference numeral 8 is a rivet, reference numeral 10 is a can body, reference numeral 11 is a folding line, reference numeral Reference numerals 70 denote seals.

FIG. 4-A is a plan view of a completed pull tab table (front) surface manufactured based on FIG. 5-A. Reference numeral 4 denotes a pull tab body, reference numeral 8A denotes a rivet hole, reference numeral 21 denotes a half-moon hole, reference numeral 22 denotes a tongue-shaped portion, reference numeral 24 denotes a finger hole, reference numeral 25 denotes a nail hook, reference numeral 17 denotes a management code. Each part is shown.

The management code display section only needs to be able to print the management code on the transition between the finger hole and the meniscus or on the other pull tab surface. The control code must be visible at all times.

FIG. 4-B is a plan view of the back surface of FIG. 4-A. The printing field boundary line 12 indicates that the printing field 1 is at a position that does not hinder the rivet mounting operation. Reference numeral 1 denotes a printing field, reference numeral 2 denotes a two-dimensional code, reference numeral 4 denotes a pull tab body, reference numeral 8A denotes a rivet hole, reference numeral 12 denotes a printing field boundary line, reference numeral 26 denotes a caulking edge, and reference numeral 70 denotes a seal. Each is shown.

FIG. 5-A is a basic plan view of the pull tab of the present invention before the forming process. Reference numeral 2 is a two-dimensional code, reference numeral 8A is a rivet hole, reference numeral 11 is a folding line, reference numeral 13 is a first mold part, reference numeral 14 is a second mold part, reference numeral 15 is a contour band, Reference numeral 16 denotes a contour band crossing portion, reference numeral 17 denotes a management code display portion, and reference numeral 70 denotes a seal. The first mold part and the second mold part, the printing field and the two-dimensional code to be printed, even if the first mold part and the second mold part are cut out from the sheet metal material, the sheet metal material main body is the contour band crossing part , The printing field is wider than the pull tab, and the management code display section can be located anywhere, and can be always visible when attached to the can lid.

FIG. 5-B is a diagram in the case where the first mold part and the second mold part are adjacent to each other on the left and right, which produce the same effect as FIG. 5-A. Since the description is repeated, it will be omitted.

FIGS. 13-1 to 5 show a process in which the pull tab, the printing field, and the two-dimensional code are fixed or integrally formed.

FIG. 13-1 shows that the printing section of the two-dimensional code is calculated on the sheet metal material, and in addition, the coating section is determined.

The print section is the position where the two-dimensional code is printed.

The painting section refers to a section in which the section including the position where the two-dimensional code is printed is painted black in advance in order to improve the two-dimensional code recognition rate of the mobile terminal. The center point of the paint zone and the print zone is the same. The color to be painted is not limited to black, and other colors may be used as long as the difference in brightness is expressed greatly when printed with a laser marker and the portable terminal recognizes and reads it as a two-dimensional code. In general dark colors are suitable for this purpose.

FIG. 13-2 shows that the two-dimensional code has been printed on the defined paint section. After printing, the sticker 70 described in claim 2 may be partially pasted on the entire surface of the sheet metal material or in an appropriate place, and then the process may proceed to a subsequent cutting step.

FIG. 13C shows that the first mold part and the second mold part are cut out with a contour band on the basis of the position of the printed two-dimensional code. At this point, the sheet metal material is a flat plate.
Rivet holes, meniscus holes, and finger holes penetrate.

FIG. 13-4 shows that after the first mold part and the second mold part are pushed down to a position below the flat plate, the first mold part is molded, and the second mold part is placed under the first mold part. FIG. It can be seen that a part of the second mold part (printing field boundary line) appears to cover the half-moon hole 21 and is in close contact appropriately.

FIG. 13-5 is a diagram in which the first mold part and the second mold part are in close contact and pressed together, and the left and right ends of the second mold part wrap around both ends of the first mold part, and are caulked. is there. This completes the intended pull tab. Then wait for installation.

FIG. 8 shows that the manufacturing process of FIG. The beverage can with the pull tab manufactured in this way is a so-called steion tab type can. Reference numeral 50 denotes a long sheet metal material main body, reference numeral 51 denotes a trace after the pull tab is removed, and reference numeral 52 denotes a completed pull tab main body before attachment. Although not shown in the drawing, the width of the caulking end portion is wider than the width of the pull tab (the shorter dimension), so that it protrudes from the contour band, so the contour band needs to be a little wider.

FIG. 14 shows a process in which the pull tab and the can lid are fixed or integrally formed.

FIG. 14 is a conceptual diagram of the process of fixing or integrally molding the can lid and the pull tab. The processes 1 to 3 are the can lid rivet molding process, 4 to 5 are the score processing process, and 6 is the pull tab attachment. 7 indicates that the attachment is completed.

Returning to FIG. 1, the two-dimensional code 2 is fixed or integrally formed with the printing field 1, the printing field 1 is fixed or integrally formed with the pull tab 4 body, and the pull tab 4 is fixed or integrally formed with the can lid 9. Has been. Therefore, the two-dimensional code is fixed to the can lid or integrally formed.

In FIG. 2, since the two-dimensional code is fixed or integrally formed with the pull tab, the two-dimensional code is not 100% exposed, and the purchaser of the can drink does not see the two-dimensional code at the time of purchase. Or even if a part of it can be seen, it cannot be read using a mobile phone or the like.

In FIG. 2, when the operation of putting the finger under the pull tab and starting the pull is started, the pulling angle is about 15 degrees, and the can lid 9 starts to tear along the score line. At the same time, “Pushu” or “Kappa” The sound is emitted. The container undergoes an irreversible shape change and the contents overflow with it.

The purchaser has not yet seen the two-dimensional code even when the content overflows around 15 degrees.

If you pull up to an angle where you can drink (pickup angle around 30 degrees), drinking and drinking is suitable for human behavior.

At this angle, it is still not possible to read on a mobile device.

No one drinks with the pull tab pulled up to an angle where the two-dimensional code is easy to read (pickup angle around 110 degrees). The pull tab is uncomfortable against the upper lip.

Therefore, it can be understood that the can beverage with the two-dimensional code of the present invention can be read only after the can is opened and not read after drinking.

In this way, it is understood that the feature of the can equipped with the pull tab of the present invention is “the can open first, then read”.

Describes the anti-fraud mechanism.

The fraud prevention mechanism is a mechanism that prevents a person who does not own the two-dimensional code attached to the beverage can held by the store or others from reading the two-dimensional code printed on the beverage can without the consent of the owner. To tell.

For example, the contents of a can beverage are considered as being filled with beer, sparkling liquor or carbon dioxide.

It is assumed that a two-dimensional code that cannot be read unless the can is opened is printed on the beer can, and a “cook” using the two-dimensional code is attached.

There are no buyers who can open a can and read a two-dimensional code in order to participate only in “籤” and do not drink beer.

On the other hand, if you can read the 2D code without purchasing or opening the can, and you can participate in “参加”, there are people who participate only in “籤”. This person is the performer of cheating.

In the present invention, since the pull tab and the printing field are fixed or integrally formed, the printing field is not exposed even if the pull tab is swung horizontally by 90 degrees horizontally with the rivet as the center of swiveling. It is not exposed and cannot be read.

Even if the pull tab is slightly pulled up in the vertical direction to pull out the print field from the gap, it is fixed or integrally formed and cannot be pulled out.

If it is forcibly extracted, the printing field, pull tab, and 2D code displaying the 2D code will be destroyed.

The operation of raising the pull tab that shields the two-dimensional code and exposing the two-dimensional code is the same operation for both the purchaser and the non-purchaser (who is assumed to be a fraudulent person).

In order to read the two-dimensional code under the pull tab for the non-purchaser, the present invention raises the pull tab as a shield and overflows the contents while causing an irreversible change in the shape of the beverage can. And a phenomenon suitable for the laws of nature accompanied by sound such as “Pushu” or “Kappa” as a fraud prevention mechanism.

The portable terminal 5 can read the information encoded in the two-dimensional code, decode it, send it to the beverage manufacturer's server 6 and start communication for the first time.

The order of “can open first, read the two-dimensional code after drinking” provided by the present invention is in accordance with the laws of nature, and the purchaser's actions are performed accordingly.

This fraud prevention mechanism is realized because the two-dimensional code is fixed or integrally formed with the pull tab.

Moreover, since the purchaser can only read the two-dimensional code after drinking the canned drink, the timing at which the questionnaire can be answered is limited to after drinking.

Therefore, it is possible to reliably collect questionnaires of purchaser evaluations after drinking.

In other words, a system was created that only collected evaluations after drinking.

However, since the purchaser has the right to decide when to open the bottle, concealment and disclosure can be made freely according to the timing of drinking.

The point of making the pull tab less environmental load such as resource saving, energy saving and recycling performance is shown in the manufacturing method stage.

The problem “beverage can with fraud prevention mechanism” imposed on the first invention has been realized.

The description is limited to an example in which the seal 70 is used (items related to the seal).

The surface of the two-dimensional code printed on the printing field 1 of the pull tab is covered with an opaque seal 70 describing information.

Describe the multiple entry function that uses this sticker.

When the pull tab is pulled up and opened, the seal covers the two-dimensional code.

The seal 70 plays a role of concealing the two-dimensional code when the pull tab is pulled up, and has a property of being easily peeled off.

On the side of the seal that is not the two-dimensional code side, information indicating the function as a lottery ticket, the function of a voucher, or an application ticket is described.

The information described on the sticker may be a keyword for accessing the two-dimensional code 2 covered by the sticker.

Or it can be just a note.

The two-dimensional code has a new interest when combined with the information of the server 6,
It is desirable to use it as a combination of information.

On the two-dimensional code side of the seal, information different from the front surface of the seal can be written.

When the three types of information are combined, the combination of time difference and interest becomes the basis for more projects.

By using the two-dimensional code function that cannot be read without opening the can, you can get more benefits than other applicants by answering the questionnaire by how many hours after opening the can You can also promote application to the questionnaire.

The sticker is a printed matter that has a function to display information, so when exchanging information via a two-dimensional code, it plays the role of a keyword, and consumers want to participate in sales promotion plans including information exchange Give a trigger role.

For example, it is assumed that the number “5” is written on the seal. Those who participate in the project using the “5” will receive “5 times” benefits than others.

Combining information performed via a two-dimensional code, a game that has never existed can be played.

If you collect “people” as much as the number “5”, you may be able to participate in a new game using the mobile phone of the people you collected. However, if they are similar to these embodiments, a similar one may be realized without the seal 70.

Describes the method of use where the identification number is limited to a sequence of natural numbers.

Take 6 beers as an example.

The identification number of the two-dimensional code encoded in the two-dimensional barcode 2 is a natural number without consecutive missing numbers from N to M.

Assume that the two-dimensional code identification numbers of six beers are consecutive, such as N to M.

The beer sold is an integer multiple of 6. The server can easily grasp the LOT.

The server can easily manage each LOT number for each LOT of beer, and the load on the server is reduced.

With the same capacity server, more beer LOT units can be managed.

Suppose that one of six of the same LOT has been drunk first.

The server 6 is accessed by reading the two-dimensional code.

In the server 6, six identification numbers are managed as one LOT.

The time at which one of the 1 LOT is drunk and accessed is taken as the access start time of the LOT.

The server replies to the mobile terminal that sent the message “Permit access until after OO time” based on the beer that made the first access based on the time allowed for access from the remaining five beers. To do.

By doing so, it is possible to promote responses such as LOT unit questionnaires.

For example, if you drink the first one of LOT, you can easily apply the remaining five if you do not apply within 24 hours.

In this way, the system contributes to promoting early consumption of LOT units.

In addition, in the case of a 6-unit LOT, a cooperation degree contest for a questionnaire response can be performed in six accumulated times required for an answer from the first access time of the first to the last access time of the sixth. By doing this, when eating and drinking in a group, a common topic and a common experience can be made, so the venue is exciting, eating and drinking is promoted, and the sales promotion effect is enhanced. Promotion planning and questionnaires that have never been realized in the past are now possible.

By using such a series of identification numbers, it is possible to notify the drinker of the limited operation from the response start time to the response end time in units of LOT, and use it as a new incentive for the group, which can be used in a questionnaire survey system for new product development.

The method for manufacturing the pull tab described in the first embodiment will be described from the step of setting the first mold part and the second mold part on the sheet metal material.

A step of setting a pull tab in the first mold part and a printing field in the second mold part.

The manufacture of the pull tab of the present invention starts by determining the center position of the two-dimensional code printed on the sheet metal material.

The position setting of the first mold part and the second mold part (determining the center position of the two-dimensional code) determines the center position of the two-dimensional code to be printed on the second mold part and marks the position. Not that.

Based on the numerical values of the specifications of the long sheet metal material and the shapes and numerical values of the first mold part and the second mold part, the center position of the printing operation of the two-dimensional code in the second mold part is determined. That is.

The center position data of the paint section and the print section is input to the controllers of “Coating Machine” and “Laser Marker”. This is the assignment. That is, it is to determine numerical data necessary for allocation.

The center position of the two-dimensional code is used as print section data and is also the center of the paint section.

A step of providing a management code display section on the pull tab.

Determine the center position of the 2D code and determine the position of the management code display. What is necessary is just to select a place where it is easy to see as shown in FIG.

A step of setting a printing field in the second mold part and painting the printing field in black.

Once the position data is input to the “painter” and “laser marker” controllers, the painter is ready to paint.

In order to improve the recognition rate of the two-dimensional code to be printed, the printing place, that is, the position to be painted is painted.

The step of determining the printing section of the two-dimensional code in an array.

It is also possible to calculate the relative positions of the two-dimensional code rows and columns in an array. If the printing sections are shifted and assigned, it is easy to secure a working space for processing machines such as presses later.

A step of printing a two-dimensional code using a laser marker on the painting section.

FIGS. 13-1 to 5 show the process of manufacturing one pull tab, but the actual mass manufactured is manufactured as a continuous body as shown in FIG.

The server 6 generates information (including an identification number and the like including the URL accessed by the portable terminal 5) generated by the laser marker 3 (not shown) by the server 6 and transmits the information to the laser marker 3.

The laser marker 3 prints the received information at the position of the print field 1 on the sheet metal material in accordance with the print section data while sequentially converting the received information into a two-dimensional code.

A step of printing a management code on the management code display section.

Following the printing of one two-dimensional code, one management code is printed on one pull tab.

As the two-dimensional code printing means, an ink jet printer or a laser printer may be used instead of the laser marker.

Even if the identification number encoded in the two-dimensional code is composed of simple identification number logic, N
To a number sequence suitable for LOT number management based on a natural number without consecutive missing numbers from M to M, or a unique identification number.

Normally, the identification numbers are encoded and printed on the two-dimensional code in ascending or descending order, so the sheet metal material after printing will not be a problem if it is attached to the can lid immediately after printing. If the sheet metal material is not rewound from the work site, the identification numbers are reversed and the LOT number management is hindered.

Cutting out the first mold part and the second mold part from the sheet metal material;

FIG. 13C shows that the first mold part and the second mold part were cut out along the contour band 15 before the molding process, based on the printed position of the printed two-dimensional code. . At this point, the sheet metal material is a flat plate.

As shown in FIG. 5-A, the first mold part and the second mold part are adjacent to each other, and the rivet hole 8A, the half-moon hole 21, and the finger hole 24 are cut out at this point, and the sheet metal material body and the first mold part are The second mold part is connected to the sheet metal material main body at the contour band crossing part 16.

Pressing the pull tab body against the first mold part to form the pull tab body.

The first mold part 13 and the second mold part 14 are folded and pushed down to a position below the flat surface of the sheet metal material while the first mold part and the second mold part are connected to each other at the crossing part. Securing the working space, first, the outer peripheral portion of the first mold part is bent to form a pull tab shape, and further, finger holes and the like are formed to increase rigidity.

A step of bending the printing field of the area including the two-dimensional code of the second mold part;

Next, as shown in FIG. 13-4, the second mold part is folded and overlapped on the back of the first mold part.

Next, as shown in the lower part of FIG. 16, the first mold part (printing field 1) is formed after the pull tab is completed in accordance with the process of bending the second mold part (printing field 1) at the lower part of the first mold part. As the processing of the nail hooking portion 25 (the portion that becomes a mechanism that makes it easy to open the can), which is the position where the finger or nail on the side is hooked, the portion of the second molding die portion corresponding to this position is deeply recessed to perform the first molding It is wound around the mold part and molded, and then brought into close contact with the back of the pull tab.

By doing so, it is possible to form a shape providing the same function at the same position as the claw hooking portion 25 at the tip of the pull tab, which is in the conventional pull tab, and the pull tab is structurally strong.

Pressing the first mold part and the second mold part relatively close to each other and pressing the pull tab main body and the printing field from above and below to integrally form the first mold part and the second mold part;

Next, as shown in FIG. 4-A, the first mold part and the second mold part are in close contact with each other so as to wrap both ends of the first mold part at the left and right ends of the second mold part. 2 The both ends of the mold part are bent, and the first mold part and the first mold part are squeezed by crimping the leading edge part, whereby the first mold part and the second mold part are fixed or integrally molded.

The management code is displayed in the management code display section so that the serial number necessary for various management of the pull tab can be visually checked in the information encoded in the two-dimensional code so that it can be seen from the surface of the can lid surface. Printed. Or if it is the surface of a pull tab, you may print in the part pinched by the finger hole and the meniscus. The timing for printing the management code printed here follows the printing of the two-dimensional code.

The target pull tab with a two-dimensional code was formed on the long sheet metal material of FIG.

The long sheet metal material of FIG. 8 shows a trace 51 in which a pull tab is attached to a can lid, the completed pull tab 52 and the long sheet metal material main body 50 of FIG.

Moving the pull tab to the can lid assembly process;

As shown in FIG. 14, the sheet metal material main body FIG. 8, which is a continuous body of pull tabs, is moved to a process in which the score processing of the can lid has been completed. A step of separating and forming the pull tab from the sheet metal material.

The pull tabs formed on the long sheet metal material are cut one by one at the contour band crossing portion 16, and the contour band crossing portion 16 is bent to adjust the shape.

Riveting the pull tab to the can lid.

As shown in FIG. 14, on the can lid after completion of the score processing or the like, the sheet metal material body that is a continuous body of pull tabs, and the pull tabs that are cut one by one from the contour band crossing portion 16 from FIG. After bending and shaping the shape, move it over the can lid and cover the rivet with the rivet hole.

Or even if you change the process so that the pull tabs are separated from the long sheet metal material as a single unit, stacked in the order of the encoded identification numbers, packed, and inserted into the process of uniting with the can lid at another time good. It can be made in stock.

The advantage of these series of work steps is that the sheet metal material can be processed only from the direction of one surface, and it is not necessary to reverse the entire surface of the sheet metal material.

A can lid with a pull tab with a two-dimensional code was formed.

About the pull tab manufacturing method using the printing field 1 piece of Drawing 6-D and Drawing 7-D.

When using the “printing area 1 piece printed with a two-dimensional code” shown in FIG. 6 and FIG. 7, neither the printing on the piece nor the technology for producing the piece is anything special, and the mounting technique is “kashing”. "Electric spot welding" is not special either.

Therefore, it is recommended from the viewpoint of effective use of existing facilities.

The series of processing equipment and techniques required by these are processes and modifications to the jigs and techniques used in the existing can manufacturing process, and can be realized at any time.

It is easy for the current sheet metal material processing technology for processing a part of the can lid instead of the rivet.

The finished can lid with the pull tab attached has no change in the external dimensions of the conventional product and the product of the present invention that would hinder assembly.

The method of FIGS. 6-D and 7-D produces a pull tab by the same process as the conventional pull tab production equipment,
This is a method in which a single printing field single piece separately manufactured is combined with a pull tab.

6A to 6D and 7A to 7D can make the pull tab main body and the small piece of the printing field 1 separately, so that the change of the process of making the existing pull tab can be reduced.

This is a conventional manufacturing process in which a two-dimensional code is printed on a single sheet metal material or a long sheet metal material, processed into small pieces, and one small piece of printing field is attached to the pull tab main body through the same process as conventional pull tab processing equipment. It is a method that is technically easy to introduce, using a lot of equipment and methods used to complete a can lid that can be used for the same purpose as the pull tab of the present invention with a little new equipment.

One small printing field can be produced using conventional production equipment.

In short, the goal is completed by attaching a small piece of printing field to a pull tab that has been manufactured as usual.

However, care must be taken when displaying a management code using a small piece of print field. The occurrence of this problem is the biggest drawback of this method.

The reason is that the management code composed of serial numbers is the same as the two-dimensional code data composed of serial numbers, and the subsequent number is shifted, and all subsequent numbers are shifted between “internal” and “external”. is there. When this method is adopted, an error occurs when making the same value as the management code encoded in the two-dimensional code and the management code printed on the management code in the table. It is easy. It is difficult to make it the same value, and it costs money.

About cutting of the printing field 1 small piece of Drawing 6-D or Drawing 7-D.

The sheet metal material on which the two-dimensional code is printed is cut out to obtain a print field 1 small piece in FIG. 6-C or FIG. 7-C.

Next, the print field 1 pieces shown in FIG. 6-C or FIG.

According to the manufacturing method of FIG. 6-D, it can be seen from the size in FIG.

According to the manufacturing method of FIG. 7D, as can be seen from the size in FIG.

In addition, it is easier to make a device for making a small piece of the printing field 1.

About the method of uniting a small piece of printing field with a pull tab.

As shown in Fig. 6-D, a printing field 1 in which a two-dimensional code is printed on a pull tab manufactured by a conventional facility.
Install the pieces in close contact.

As shown in FIG. 7-D, a printing field 1 in which a two-dimensional code is printed on a pull tab manufactured by a conventional facility.
The small pieces may be brought into close contact and attached by electric spot welding.

FIG. 6-D is a cross-sectional view of the pull tab after merging.

FIG. 7-D is a cross-sectional view of the pull tab after merging.

Regardless of which manufacturing method is selected, the pull tab and the printing field 1 are fixed or integrally formed (unintegrated with each other).

Other issues.

It adds about the component of this invention.

About management code.

A set of data that cannot be referred to each other of a large number of items, “Management code written inside” and “Management code written outside” cannot be referred to each other. Guaranteeing (maintaining the same value) is very difficult in practice. Its execution is costly.

Subsequent to the operation of printing the two-dimensional code, this problem can be solved by printing the management code on the first mold part on the same plane.

If it does so, a printing process can be continued with a laser marker and it can print without a loss of time.

Describe how to use the management code.

Regardless of the management code, consumers can read the two-dimensional code and participate in sales promotion projects.

This is because the consumer does not judge whether or not the information read and displayed is himself / herself, but judges the transmitted data on the server side.

Without the management code, the manufacturer cannot refer to the information encoded in the two-dimensional code from the outside of the can.

This is because the beverage can filled with the contents has a mechanism in which the two-dimensional code is concealed by the pull tab.

The manufacturer needs to be able to refer to the data of the two-dimensional code from the outside.

If you can't refer to it, you won't be able to manage sales promotions, manage sales promotions, or manage production.

Therefore, it is necessary to print the management code at a position where the manufacturer can see it.

However, it should not be possible to infer the contents of a two-dimensional code that has not yet been opened (unused) from the specified management code. Therefore, it becomes necessary to encrypt or hide the two-dimensional code.

The data displayed on the management code display unit is necessary for the manufacturer.

It can be used only by the manufacturer.

If it is a position where it becomes flat after pull tab molding of the first mold part of FIG. 5-A, printing may be performed anywhere, and since it is a laser marker, it can be printed finely. In order to reduce the number of digits, the management code may be printed using only the alphabet, not numbers.

Care should be taken when displaying a management code using a small piece of printing field. It is easy to make a mistake in making a set of data of “a management code encoded in a two-dimensional code” and “a management code printed in a management code printing unit” the same value. However, these concerns do not arise in the case of FIGS. It can be guaranteed that the set is correct. This is because it is printed on the same plane of the same sheet metal material and is folded and turned upside down.

Along with printing 2D codes, a management code (usually a manufacturing serial number, etc.) used in manufacturing, LOT management, etc., of the information encoded in the 2D code is not a printing section. Sometimes it prints at a position where it can be read without causing it.

This number is called a management code, and the position where the management code is displayed is called a management code display section.

About laser marker, sheet metal material and paint.

An investigation was conducted to pursue a faster printing speed of the laser marker.

In FIG. 16, reference numeral 60 is a sheet metal material, reference numeral 61 is a black paint, and reference numeral 62 is a white paint.

The laser marker can adjust the irradiation energy. The counterpart substance irradiated with the amount of energy per unit time to be irradiated differs in the degree of denaturation (degeneration or change).

A paint that can be easily denatured in a shorter time than metal was applied to the sheet metal material, and after waiting for drying, a two-dimensional code was printed on the painted surface with a laser marker.

Here, the depth at which the paint applied to the sheet metal material is peeled can be adjusted.

In the first test, the sheet metal material 60 was directly irradiated.

FIG. 16 shows that in the second test, a black paint 61 was applied on the sheet metal material 60 and dried to perform a printing experiment.

Adjust the thickness of the paint and remove the black. The laser beam partially peels off the sheet metal material. If the sheet metal material is white, it should be possible to print faster by removing the black paint.

FIG. 17 shows an experiment in which a black paint 61 was applied on the sheet metal material 60 and a white paint was further applied in the third test.

Calculate the paint thickness and remove the white paint. Some bite into black paint. It should be possible to print the two-dimensional code faster by removing the white paint.

However, the result was that the white paint layer could be printed sooner, but it was not as expected, but it was faster when the black paint was applied on the sheet metal material.

Describe sheet metal materials.

The width | variety of a sheet metal raw material should just be a width | variety which can cut out, press, and shape | mold a multiple row simultaneously like FIG.

Where to print 2D codes.

1) A reading error is likely to occur depending on a printing place.
2) The image is distorted in the displayed two-dimensional code depending on the shape of the printing place.
3) The cause of distortion is that the printed two-dimensional code is deformed when there is a physical deformation at the display location. The two-dimensional code has an error correction capability against deformation (up to 25% of data loss, fouling and deformation can be corrected), but there is a limit to the cover.
4) Furthermore, since a two-dimensional code is photographed as an image with a mobile terminal, the image is distorted or halated by exposure to light, resulting in a phenomenon in which the reading rate decreases.
5) This is why it is desirable to print on a flat place.
6) In the two-dimensional code, since the information is recognized by using the difference in brightness between adjacent cells, the reading rate is reduced or cannot be read depending on the material of the printing field 1 being printed.
7) Even if the display size of the two-dimensional code is too large or too small, the reading capability of the portable terminal cannot be supported.
8) If “distance” cannot be switched in the shooting mode, even if the display size of the two-dimensional code is too large or too small, it will not fit in the appropriate read image size as an image, and focusing will not be possible. The terminal cannot be analyzed as a two-dimensional code. It is necessary to print based on the characteristics of these two-dimensional codes.

About reading inspection.

Next, 100% inspection is performed to determine whether or not the printed two-dimensional code can be read by a two-dimensional code reader.

While the laser marker is printing, reading inspection is performed in parallel. During this time, there is no time loss because the sheet metal material is stationary.

About the features of laser marker printing capability.

For practical application of the present invention, it is necessary to print a large number of two-dimensional codes at high speed.

As the amount of information increases, the laser marker printing speed decreases.

The laser marker gives energy to the irradiated partner, the material of the partner is denatured by that energy, and the brightness of the surface of the material changes.

Is it easy to read a two-dimensional code when it is irradiated to paint or metal? Although it depends on the light source and output of the laser marker, in many cases, it is easier to denature the paint.

Even for a laser marker, it is easier to remove a softer one than to remove a hard one.

By modifying or peeling the painted surface, a difference in brightness occurs on the painted surface.

The difference in light and darkness on the paint surface is easier to read than the difference in light and darkness on the surface of the sheet metal material.

If the resin is peeled deeply, a two-dimensional code can be expressed by the difference in brightness between the surface of the sheet metal material and the resin, but there is a drawback that it takes a long irradiation time to peel deeply.

Whether a lot of energy can be irradiated depends on whether it is irradiated for a long time or a high-power machine.

About laser marker printing characteristics.

This is the case of printing on an ink-free material, for example, printing on metal or glass.

Furthermore, it is printing on things that do not want to use ink, printing on food itself.

Furthermore, it is optimal when printing on objects that are covered with water after printing, or when exposed to beer or beverages overflowing after opening, especially in an environment where ink such as water, alcohol or organic solvent is likely to bleed.

For the purpose of single item management, the present invention is most suitable as a method of attaching a different identification number one by one to a beverage can, concealing it, and printing it on the metal of the opening where the food comes into contact, considering the conditions exemplified above It is.

Laser markers can be the ultimate printing means.

This is because there are no consumables other than electricity bills.

No label or ink ribbon is used.

Therefore, the running cost is close to zero.

This means that the cost for the variable price of the product price is zero.

Gas-sealed carbon dioxide laser tubes are mass-produced, and maintenance work is almost eliminated.

Some fixed costs (cost for electricity and tube replacement) are required.

The laser tube has a lifetime, but it may be longer than the lifetime of the equipment.

The price is getting cheaper.

Although the printing range was narrow, a printing area of about 300 mm × 300 mm, which has become wider, has been put into practical use.

Laser markers take a long time to print a barcode, apart from a two-dimensional code.

This is because it is necessary to take irradiation time in order to obtain contrast.

The current laser marker is the most effective means for writing small characters and two-dimensional codes in a small area.

About the characteristics of the two-dimensional code.

What is the problem when printing 2D codes at high speed?
1) It is desirable to reduce the two-dimensional code.
2) If the size is the same, it is desirable not to increase the printing density of the two-dimensional code.

1) If a large number of information is encoded, if the display size is the same, the printing density (the point irradiated by the laser marker) becomes high, that is, the density becomes high, and reading errors are likely to occur.
2) As a function for covering an error, there is a method for creating a two-dimensional code in consideration of an error correction rate.
3) Increasing the error correction rate increases the redundancy of encoded information and increases the amount of information.
4) When the amount of information increases, the two-dimensional code of the same size increases the printing density and decreases the reading rate of the portable terminal.
5) In order not to increase the error correction rate and increase the amount of information, it is necessary to reduce the amount of information to be encoded. However, it conflicts with the purpose of developing a two-dimensional code (a large amount of information can be included in one two-dimensional code).
6) Since unused information (including identification number) must not be inferred from used information (including identification number), it is necessary to encrypt information (identification number) encoded in a two-dimensional code. is there. However, the amount of information encoded by encryption further increases.

About four types of printing patterns of two-dimensional code.

A continuous strip-shaped white background (actually a portion denatured by a laser) surrounding the four circumferences that separates the entire two-dimensional code symbol from the other outside the two-dimensional code will be described.

If a belt-shaped white background (hereinafter referred to as a section band) that clearly divides the four periphery of the two-dimensional code into a two-dimensional code part and other parts is provided, the reading rate of the portable terminal is improved, but the laser marker printing speed Becomes extremely slow. Details will be described later.

A band-shaped white background (hereinafter referred to as a section band) is defined as a two-dimensional code for printing with a band. Hereinafter, it is referred to as a “banded two-dimensional code”.

A band-free white background (hereinafter referred to as a section band) is defined as a two-dimensional code for band-less printing. Hereinafter, it is referred to as a “bandless two-dimensional code”.

There are two types of “black” and “white” in the square section at the center of the symbol symbol (there are three in the periphery) of the two-dimensional code.

The “black two-dimensional code” in which the square section at the center of the symbol is “black two-dimensional code” is hereinafter referred to as “black two-dimensional code”.

The square section at the center of the symbol symbol is hereinafter referred to as “white two-dimensional code”, and is hereinafter referred to as “white two-dimensional code”.

The “band” “not present” and “black and white” “not present” cause a difference in whether the mobile terminal can read, whether it is readable, not readable, easy to read, or difficult to read.

A normal mobile terminal (mobile phone) is designed to read (black two-dimensional code).

Furthermore, it is designed so that it can be read regardless of whether the zone is “present” or “none”.

However, the “work amount” for printing the zone is a very heavy load for the printing capability of the laser marker.

An example in which a zone is a load on the laser marker printing capability is described.

The number of points (cells) irradiated by the laser marker constituting the “two-dimensional code with band” 9.5MMX9.5MM angle is 44 × 44 = 1936.

The experiment is based on the above-mentioned values, although it varies slightly depending on the manufacturer and model.

The number of cells constituting the original two-dimensional code is 1296.

Assuming that an average of 50% of the cells are irradiated to represent a two-dimensional code, the number of irradiated cells is 1296/2 = 648.

The number of cells constituting the zone of the banded two-dimensional code is 640.

If a band is made, the number of cells to be irradiated (work amount) will be doubled if it is not made.

This means that the work of drawing a zone with a laser marker increases.

If the entire surface of the two-dimensional code is irradiated, the two-dimensional code becomes pure white and does not function as a two-dimensional code.

If the entire surface of the two-dimensional code is not irradiated, the two-dimensional code becomes black and does not function as a two-dimensional code.

This is an illustration showing that the plotting speed is doubled straight when the section band is drawn with a laser marker.

About the characteristics of mobile devices.

What are the conditions for mobile terminals with a high 2D code recognition rate?

The two-dimensional code to be read must be recognized with an appropriate image size.

Therefore, it is necessary to switch the focus between “far” and “near”.

Appropriate image resolution is required.

The image recognition program must be competent.

Describes the interrelationship between laser markers, two-dimensional codes, and mobile terminals.

What does it mean to draw a two-dimensional code with a laser marker and read it with a portable terminal?

Considering the two-dimensional code as an aggregate of a large number of points, the laser beam causes the object to be printed to be modified according to the principle of the two-dimensional code, and a large number of points (which are areas as a set of cells) are denatured. Creates an image with a light and dark difference on the surface of the object to be printed, and recognizes it as a two-dimensional code by a two-dimensional code analysis program (one-dimensional and two-dimensional barcodes), which is one of the image processing functions of mobile terminals The mobile terminal decodes the information encoded in the two-dimensional code and causes the mobile terminal to perform the required information processing.

The interrelationship between the elements related to the good and bad reading performance that occurs between the laser marker, the two-dimensional code, and the mobile terminal is that each element has a trade-off. )).
About the two-dimensional code printing method.

Research and experiment on whether a two-dimensional code can be printed on a sheet metal material or can lid directly using a laser marker and read by a portable terminal, and what conditions should be provided for an easy-to-read two-dimensional code. went.

About the primary printing test.

There are two types of printing conditions: a non-painted sheet metal material (hereinafter referred to as a white fabric) and a gold-colored can lid (hereinafter referred to as a gold fabric).

The print sections were divided into three locations A, B, and C (directly below the pull tab and at the pull tab end boundary, but outside the boundary, but where the two-dimensional code is partially hidden by the pull tab and can only be read after opening).

The print size is 14X14MM (referred to as B-14), 12X12MM (referred to as B-12),
10 × 10MM (referred to as B-10).

The amount of data to be encoded is 130 digits and 170 digits.

Two types of commonly used mobile phones were used as mobile terminals.

A two-dimensional code was printed by combining the print section, print size, and data amount, and a reading inspection was performed.

The inspection result is shown in FIG.

As a result of the experiment, the information that I wanted to know most was “the time required to print one two-dimensional code that can be read by a portable terminal”.

The primary print test does not give instructions on which to perform the test with the banded 2D code, bandless 2D code, black 2D code, or white 2D code. I asked.

As a result, the following was found.

The material printed on unpainted sheet metal material (hereinafter referred to as white fabric) was readable by the laboratory two-dimensional code reader, but was not readable by the mobile terminal (hereinafter used in the same meaning as a mobile phone).

In many cases, the bandless two-dimensional code cannot be read by a mobile phone due to the reflected light of the sheet metal material.

The standard printing “white two-dimensional code” in the laboratory could not be read with a mobile phone.

The reason why the printing time can be shortened was found to be as follows.

In order to denature the metal sheet metal until it develops white, it is necessary to irradiate the laser beam with a lot of energy for a long time.

If the coating is modified rather than modifying the metal, less energy is required for modification. Irradiation time is short.

Depending on the case (depending on the thickness of the coating, etc.), the thin coating disappears more than the denaturation due to a large amount of energy irradiation, the sheet metal material of the background appears, and it plays the role of white denaturation. You can print a readable two-dimensional code. By doing so, a faster printing time may be realized. It is thought that a combination of many elements is necessary for elucidation of these.

Whether the printed two-dimensional code was too large or too small, it could not be read depending on the reading performance of the portable terminal (with or without the ability to switch the focus).

The reading performance was found to be highly model dependent.

The conclusion of the first experiment was that the 9.5 MM square two-dimensional code with a printing speed of about 1 second was fast, but could not be read by a portable terminal.

What can be read was found to be impractical because the printing speed of one piece was as slow as 20 to 47 seconds.

About the secondary printing test.

Based on the results of the primary test, it is assumed that the time required for creating a readable two-dimensional code is shorter when the colored surface is modified and colored than when the sheet metal material is modified and whitened. Did.

The printing conditions are black-coated sheet metal material (hereinafter referred to as black fabric).

The print size is 12X12MM (referred to as B-12), 11X11MM (referred to as B-11),
10 × 10MM (referred to as B-10), 9 × 9MM (referred to as B-9), and 8 × 8MM (referred to as B-8).

The amount of data to be encoded prepared 60 digits and 130 digits.

The printing section was one type of black-coated sheet metal material (hereinafter referred to as black fabric), and two types of laser markers, YVO4 and CO2, were prepared.

The inspection result is shown in FIG.

The information I want to know most is "What are the conditions that can be read by a portable terminal and have a high printing speed? It depends on the laser light source.

In conclusion, the CO2 laser was found to be unsuitable for use in printing metal sheet metal.

It has been found that a black-coated sheet metal material has a strip-shaped white background (hereinafter referred to as a section band), and a data amount is small, the printing speed is as fast as about 1 second per one and the reading rate is good.

About the third printing test.

The printing conditions are: a black-coated sheet metal material (hereinafter referred to as a black fabric), a printing size of 6 × 6MM (referred to as B-6), 7 × 7MM (referred to as B-7), 8 × 8MM (referred to as B-8), 9 × 9MM ( (Referred to as B-9) and 10 × 10MM (referred to as B-10).

The amount of data to be encoded is 60 digits and 80 digits, which are even smaller.

The printing section was a kind of sheet metal material plate (hereinafter referred to as a black fabric) of a black painted fabric, and the laser marker was performed by the YVO4 method.

The inspection result is shown in FIG.

The most important information is "What are the conditions that can be read by a mobile terminal and have a high printing speed?"

The conclusion is that a YVO4 laser marker is used, and the sheet metal material of the black paint fabric has a strip-shaped white background (hereinafter referred to as a section band), and the data amount is small, but the printing speed is fast and approximately 0.6 seconds per one. We were able to conclude that it was printed on average and the reading rate on mobile terminals was good, so that it could be provided practically.

Recommended 2D code.

The printing size of the two-dimensional code may be 6 to 10 mm square.

When a 6 to 10 mm square two-dimensional code is printed, the printing speed is fast and the marker productivity is the highest.

Printing with 6 to 10 mm square is the cheapest to print on the printing place 1.

The pull tab has a width (shorter side) of about 12 mm, and a position for sufficiently storing the printing field 1 of the present invention can be secured.

If it is a 6-10 mm square, a flat space without a smooth distortion can be secured in the printing field 1, and four types of mounting methods for the printing field 1 can be selected and implemented without any trouble.

There is a need to reduce the cost of printing two-dimensional codes.

About laser marker printing cost.

The purpose of the research is to reduce the cost of the display method as compared with the display method of the two-dimensional code generally used conventionally. Therefore, how to print a two-dimensional code that encodes the amount of data suitable for the purpose of use at high speed. Can the printed two-dimensional code be read? By referring to the result, the cost required for display per two-dimensional code is to be examined.

As a result of these three experiments, it has been found that it stably cuts 60 seconds / piece with a size of 6 to 10 mm square.
The printing capability of this laser marker when it operates 365 days 24 hours is 365 × 24 × 60 × 60 = 31536000 / year or more. The price of one laser marker is around 7 million yen.

It turned out that the printing cost of the laser marker should be considered starting from 0.22 yen / piece.

About label printing costs.

Next, a two-dimensional code in which two layers of base materials as shown in FIG. 4 of JP-A-2006-58767 are laminated so as to be peelable is printed.

A pattern Random number printing only 2 layers seal 10 million sheets 0.40 yen / sheet 100 million sheets or more 0.30 yen / sheet D pattern Variable QR + random number printing double layer seal 10 million sheets 0.45 yen / sheet 100 million sheets More than 0.35 yen / sheet size 20mm × 15mm
On paper White PET 50μ
Bottom YUPO 80μ strong adhesion re-peeling type printing Top 1 color / 1 color
Bottom 1 color + printing finish roll (1 roll 20000 rolls)
The print data must be supplied.
B / C pattern Single layer seal 10 million sheets 0.18 yen / sheet 100 million sheets or more 0.16 yen / sheet

The production cost for paper labels is the D pattern. Variable two-dimensional code + random number printing two-layer seal. It was found that 0.35 yen / sheet should be compared for more than 100 million sheets.

As a result of the experiment, it was found that the printing cost of the two-dimensional code was significantly cheaper with the laser marker.

About can body, can lid and pull tab as display media.

The beverage can has three components: a can body 10, a can lid 9, and a pull tab, and each can serve as a display medium.

The two-dimensional code displayed on any of the three components is the same in that it is displayed, but the cost of creating the anti-fraud effect, concealment of the two-dimensional code, exposure function, and anti-fraud function In consideration of the effect, the display of where to display is naturally limited.

The two-dimensional code cannot be concealed simply by printing on the can body with a laser marker. A separate concealment mechanism is required, increasing costs.

As shown in FIG. 12, when displayed on the can lid, if the pull tab is turned 90 degrees or more on the horizontal plane with the rivet as the center of turning on the horizontal plane, the printing field may be exposed and the two-dimensional code may be read.

When a seal printed with a two-dimensional code is attached to the pull tab by an adhesive, the print field may be read after the pull tab is slightly lifted and the print field is pulled out from the gap.

Furthermore, if it is forcibly pulled out and read, the seal is broken and the reading cannot be performed. If a non-purchaser performs such a thing at the store, the corresponding product is ineligible as a product although there is no excess or deficiency in the contents.

Fortunately, when making the can body, can lid, and pull tab of the component parts, the manufacturing equipment becomes smaller in order, the manufacturing process is simplified, equipment development cost, equipment procurement cost, running cost, The number of personnel is also reduced, and the overall display cost of the two-dimensional code is reduced.

The result of studying the problem for each of the above three components is the reason why the two-dimensional code is displayed by being fixed to the pull tab or integrally molded.

For the realization of the present invention, it is necessary to minimize the renewal of existing facilities, process changes, materials, and manufacturing methods of businesses related to current canned beverages.

It is desirable that the manufacturing process from the production of the pull tab to the attachment to the can lid is carried out in a consistent flow from sheet metal material development, painting, printing, cutting, caulking, pull tab completion, and riveting to the can lid.

By doing so, it is possible to minimize the renewal, modification and replacement of the current equipment.

Finally, by organizing the process while considering many of these issues in advance, the present invention does not change the manufacturing process of the can body constituting the beverage can and before the can lid (before the pull tab is attached) Complete the “can lid with a two-dimensional code that can be read after opening” by making a few changes to the pull tab manufacturing process and the process of attaching to the can lid, without any changes to the manufacturing process. It is understood that

Renewal and change of manufacturing and assembly process of each part, development of new equipment, update and change, etc., update of existing facilities related to canned beverages, change of process, The problem of the invention of minimizing changes in materials and manufacturing methods has been realized. Therefore, it is easy to employ the present invention for manufacturing a beverage can.

The technical scope of the present invention is not limited to the illustrated embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, in the embodiment, other methods may be used as long as the can lid and the two-dimensional code are fixed or can be integrally formed.

A specific example of the concealment structure will be described. For example, FIG. 1 is an example in which a concealment structure is realized using a pull tab of a beverage can. In this case, the article to which the two-dimensional code 2 is attached is the beverage can. According to the invention of claim 4, the beverage can is structured to be opened by an operation of exposing the two-dimensional code by the concealing structure. For example, it is assumed that the beverage can attached with the two-dimensional code 2 is a can beverage sold as a product, and the concealing structure is a pull-top structure as shown in FIG. Then, it is impossible to perform the action of “reading the two-dimensional code 2 without opening the can beverage and answering the questionnaire”. Therefore, it is possible to reduce the difference between the time when the can drink was drunk and the time when the questionnaire was answered, and the evaluation information of the product at the time when it was drunk can be obtained. Therefore, it is possible to obtain extremely useful information for product development.

FIG. 18 is a network diagram in the present invention. The two-dimensional code 2 is installed on the back side of the pull tab 4 in the can container 808.

The Internet 806 is a communication means for connecting the portable terminal 5 and other computers. Not limited to the Internet, any communication means such as a wired or wireless LAN or BLUETOOTH communication means may be used. In addition, it is not necessary for all connections to be the same communication means. For example, the communication between the mobile terminal 5 and the server 6 may be the Internet, and the other communication may be a wired LAN.

The portable terminal 5 is a computer terminal connected to the server 6 via the Internet 806. Further, the portable terminal 5 includes means for reading a two-dimensional code, reads the two-dimensional code 2, decodes and extracts the encoded data, and connects to the server 6 based on the decoded result data. Have means.

A user 807 is the owner of the mobile terminal 5. If the questionnaire response history (which includes both the content of the response and the time when the response was made) is tracked for the unique identification number 802A in the mobile terminal 5, the response history of the user 807 is tracked. Will be. As the identification number, an aircraft number, a telephone number, an e-mail address, etc. can be used.

The server 6 is a computer that is connected to the portable terminal 5 and the production management computer 805 via the Internet 806 and is connected to the management database 810 to read and update the data. The server 6 includes a server program, and distributes the questionnaire to the portable terminal 5 when receiving a questionnaire transmission request from the portable terminal 5, and records and statistics the result of the questionnaire response received from the portable terminal 5 and its time Have The management database 810 is used as a data storage location for recording statistics.

The production management computer 805 is a computer connected to the server 6 via the Internet 806 and connected to the manufacturing database 811 to read and update the data. Furthermore, it is a computer that manages information when the can container 808 is shipped as a product using a record in the manufacturing database 811. The production management computer 805 includes a production management program and has means for recording the can container 808 and the two-dimensional code 2 in association with each other when the can container 808 is manufactured.

A process until the two-dimensional code is attached to the can 808 and shipped is described with reference to FIG. In addition, it is clear that the steps of the S3000 series and the S5000 series operate on the server 6 and the production management computer 805, respectively. The subject description may be omitted.

By receiving the start input, the production management computer 805 starts the production management program.

In step S5001, a two-dimensional code issuance request is made to the server 6. This step is performed in order for the production management computer 805 to associate the two-dimensional code 2 with the can container 808 using the commodity recorded in the manufacturing database 811 as the can container 808.

In step S3001, the server 6 issues a two-dimensional code ID. Since the two-dimensional code ID is a unique number for each two-dimensional code, an ID that does not overlap with the already issued two-dimensional code ID is selected.

In step S3002, a data record for managing a two-dimensional code having a two-dimensional code ID is generated and recorded in the management database 810. Here, details of the management database are shown in FIG. 5 (details will be described later).

Next, the server address and the two-dimensional code ID are encoded to generate the two-dimensional code 2 as image data (step S3003).

In step S3004, the two-dimensional code 2 generated in the previous step is transmitted to the production management computer 805. In this step, although the two-dimensional code is encoded in the server 6, the encoding operation may be performed in the production management computer 805.

In step S5011, the production management computer 805 receives the two-dimensional code 2.

In step S5012, the two-dimensional code 2 received in the previous step and the can container 808 are associated with each other and recorded in the manufacturing database 811.

At this point, the preparation for shipping the can container 808 is completed.

Then, the can container 808 is shipped, and the fact that the can container 808 has been shipped is output in step S5013, and the information is recorded in the manufacturing database 811.

Next, a process from when the two-dimensional code 2 attached to the shipped can container 808 is read by the portable terminal 5 until a questionnaire is answered by the user 807 will be described with reference to FIG.

See FIG. 21 for the structure of the management database 810. In FIG. 21, PK indicates a primary key attribute, and FK indicates a foreign key attribute.

First, the terminal program operates when the user 807 operates the portable terminal 5.

In step S2001, the mobile terminal 5 reads the two-dimensional code.

In step S2002, a questionnaire transmission request is made to the server 6 based on the result of reading the two-dimensional code 2 in the previous step. In this case, information regarding the can container 808 is encoded in the two-dimensional code 2, and a questionnaire question is selected by transmitting the information. This information is a primary key attribute in the product plan 104. Includes product planning code.

What kind of lottery 103 the product planning 104 performs when answering a questionnaire for what kind of product 101, and what kind of two-dimensional code ID the two-dimensional code 202 for referring to the information has? It is a data table provided with a record that associates the above.

The question set description 107 is a data table for associating what kind of questionnaire to which product plan 104 is to be conducted. The contents of the questionnaire questions, their fields, answer methods (information such as selection formulas and description formulas), etc. are defined in the questionnaire questions 106.

The mobile terminal 105 is a data table for creating a list of mobile terminals 5 that participated in the questionnaire.

The answer detail 108 is a data table that records what kind of answer is given by which portable terminal to what kind of questionnaire question 106. Note that the same two-dimensional code 2 is read a plurality of times by the same portable terminal 5 by using a method such as referring to the attribute of the response details 108 and using whether or not the value is NULL. It is possible to determine whether or not.

In step S3101, the server 6 receives a questionnaire transmission request.

In step S3102, the process branches depending on whether the answer is the first time. In this case, the first time means that the same mobile terminal 5 is not going to make multiple responses to a questionnaire based on a certain two-dimensional code 2, or that multiple responses are made to a questionnaire based on a certain two-dimensional code 2. A plurality of patterns such as whether or not to break are considered.

The next step branches to S3103 and S3104 by the branch of step S3102.

A case where step S3104 is executed after step S3102 will be described.

From step S3104, information indicating that it is not possible to participate in the questionnaire is generated and transmitted to the portable terminal 5.

In step S2003, the portable terminal 5 displays warning information indicating that it cannot participate in the questionnaire, and the process ends.

A case where step S3103 is executed after step S3102 will be described.

In step S3103, a questionnaire question to be transmitted to the mobile terminal 5 is determined. In determining this question, methods such as setting a question pattern in advance or using a random number are employed. Alternatively, information that has already been collected can be added as a factor when selecting a question.

In step S3105, a questionnaire question is transmitted to the portable terminal 5.

When there are a plurality of questionnaire questions, if one answer is transmitted to the server 6 one by one, the processing load on the communication line and the server 6 increases. Therefore, data regarding answers to a plurality of questions may be transmitted to the server 6 in a batch. For this function, dedicated software may be incorporated in the mobile terminal 5, or a program in a script language may be transmitted to the mobile terminal 5 when a question is transmitted from the server 6.

Next, in the portable terminal 5, the received question is displayed in step S2004.

In step S2005, an answer input operation for the question is accepted. Therefore, the user 807 performs an input operation, and the process proceeds to the next step.

In step S2006, information including the answer result acquired in the previous step is transmitted to the server 6.

Next, in step S3106, the server 6 receives the answer to the questionnaire question.

In step S 3107, the answer result for the questionnaire question and the time when the answer result was obtained are recorded in the management database 810.

Next, lottery processing is performed. The lottery is conducted for the questionnaire participants. The purpose is to improve the willingness of the participants to obtain more answers.

In step S3108, a lottery is performed. The determination of winning is made by a method such as following a pattern prepared in advance, using a random number, using time, or a combination thereof.

In step S3109, the lottery result is transmitted to the portable terminal 5.

Next, the lottery result is displayed on the portable terminal 5 in step S2007. When displaying the result, an input of a destination of a product to be sent to the winner may be accepted.

Thus, a series of processes is completed.

In this embodiment, the questionnaire is started when the portable terminal 5 reads the two-dimensional code 2 and requests the server 6 to send a questionnaire. The role of the two-dimensional code 2 may be replaced by RFID or the like. it can. In this case, the portable terminal 5 is configured to have an RFID reading function.

Assume that the concealing structure is a pull-top structure as shown in FIG. Then, it is impossible to perform the action of “reading the two-dimensional code 2 without opening the can beverage and answering the questionnaire”. Therefore, it is possible to reduce the difference between the time when the can drink was drunk and the time when the questionnaire was answered, and the evaluation information of the product at the time when it was drunk can be obtained. Therefore, it has become possible to obtain extremely useful information for product development. A can with a pull tab that can be used for questionnaires to collect consumer's reaction and evaluation information after the can has been opened and the contents consumed has been realized in the investigation of canned beverage sales promotion plans did. This is an effective means for new product development.
