Description

The present invention relates to a lid for sealing a container main body that contains contents of food and drinks, and more particularly to a method for manufacturing a lid with an information code.

  Conventionally, regarding various products that are diversified, when a consumer obtains various types of product-related information, descriptions of product descriptions and instruction manuals described in individual products have been used. Also, tack seals and bill labels have been used for information on campaign information with prizes. However, the space for displaying the description of the product manual and the instruction manual is limited, and only the minimum necessary information can be described. In the case of tack seals and tag labels, there has been a problem that, when sticking these to a product, a machine for sticking is required or considerable personnel are required. Furthermore, since there is little product related information, there has been a problem of misunderstanding by consumers or misuse of products due to lack of understanding by consumers. Even in the campaign with a prize, the amount of information is small, so it takes time to fill out the necessary items on a separate postcard, which has become a big problem for both the seller and the consumer.

In order to solve these problems, in recent years, a one-dimensional barcode that provides product information or a two-dimensional code that provides more information is attached to the product, and this is read by a consumer with a terminal such as a mobile phone. In addition, services that obtain information and access information via a network to obtain information have also started. A method using an IC tag in which a very small IC chip is incorporated in an electronic tag has been developed (see, for example, Patent Document 1 or Patent Document 2). With this IC tag, it is possible to provide various information such as product information related to products, information on winning prizes, campaign information, company information, store information, product history, etc. to consumers, product distributors, etc. is there.
JP 2002-236888 A JP 2004-18003 A

  However, although the amount of information increases in the above-described method using an IC tag, a dedicated device such as an IC tag reader or an IC tag writer is required for reading and writing information on the IC tag. In addition, an antenna may be attached to the IC chip of the IC tag and information may be transmitted / received wirelessly to / from a reading device. In this case, however, a large-scale device is required. Wireless transmission and reception of information leads to leakage of consumer information.

  When product information is provided by a one-dimensional barcode, there is a limit to the data capacity that can be described, so the information is limited to minimum information such as a product code number and product price.

  When product information is provided using a two-dimensional code, the amount of information has increased dramatically due to recent development, and sufficient information can be provided to consumers. However, like a one-dimensional barcode, a two-dimensional code is usually printed, affixed, or branded (hereinafter referred to as “printing”) on the side of a container (hereinafter referred to as a one-dimensional barcode and a two-dimensional code). Alternatively, a generic name for other codes similar to this is referred to as “information code”). Therefore, when printing the information code or the like on the side surface in the manufacturing process of the container body, if the container has a polygonal cross section, a container positioning process is required to perform the printing or the like. In addition, when the information code is attached with a seal, a step of attaching the information code to a predetermined position is necessary so that the label is not always covered with the information code. In order to carry out this step, a sensor for positioning and a holding function of the container are required for the manufacturing apparatus, and the manufacturing apparatus is also expensive.

  Moreover, since information is printed in advance, it cannot be set as on-time information. For example, it is difficult to put campaign information for a limited time in the information code. In addition, a container manufacturer needs to stock a large number of container bodies that have already been printed with an information code. In this case, if the information is changed, the container body on which printing or the like is performed is wasted. In addition, the container body is usually designed to stimulate consumers' willingness to purchase, but printing information codes or the like impairs the aesthetics of the design.

  Further, printing of the information code or the like may be performed in advance on the shrink film separately from the container manufacturing process, and the shrink film may be attached in the container manufacturing process. However, the same problem as in the case of the container body, that is, the problem that cannot be made on-time information and the problem that impairs the aesthetics of the design cannot be solved.

  In addition, when an information code is attached to the side surface of the container body, it may be difficult to read if the container has a polygonal cross section. Furthermore, when the information code is printed on the side of the container, dirt is attached to the information code during transportation from manufacturing to display in the store, leading to erroneous detection of information and unreadableness. This is a big problem for information codes that are expected to become even smaller in the future.

The object of the present invention is to store the contents in the container body and write an information code on the top surface of the lid after or just before mounting the lid, so that (1) the cross-sectional shape of the container is any shape (2) Eliminates the need for a mechanism for positioning the container body (positioning in the rotational direction with respect to the shaft) in the information code applying device, (3) Providing on-time information, 4) To provide a method of manufacturing a lid with an information code that can realize that the stock of the lid with an information code is not generated.

The method for manufacturing a lid with an information code according to the present invention includes a step of writing an information code on the top surface of the lid of the container at the final stage of product manufacture, and the information code requires campaign information as on-time information. It is a two-dimensional code that encodes the information that it contains .

In the method of manufacturing the lid with an information code according to the present invention, the step of writing the information code at the final stage of manufacturing the product includes the step of mounting the lid on the container body containing the contents, and the step of mounting the lid on the container body. including form and a step mark the information code on the top surface of the lid.

In the method for manufacturing a lid with an information code according to the present invention, the step of writing the information code at the final stage of manufacturing the product is directed to the top of the lid of the container that closes the container body in a predetermined direction, and then the contents are the accommodating the said container body in the course of supplying the lid capping machine for capping comprising form mark the information code on the top surface of the lid.

  In the method for manufacturing a lid with an information code according to the present invention, it is preferable that the information code is written by ink-jet printing or a sticker on which the information code is printed. According to the above method, an information code can be written easily and instantaneously, so that it is possible to cope with a high-speed production line.

The method for manufacturing a lid with an information code according to the present invention makes it easy to write an information code regardless of the cross-sectional shape of the container body, and positioning of the container body (positioning in the rotational direction with respect to the shaft) in the information code applying device No mechanism is required. In addition, it has the advantage that it can provide on-time information and does not produce stock of lids with information codes. By writing the information code on the top of the lid of the container, it is easy to read the information code mechanically, and it is difficult for dirt to adhere to the place where the information code is written. . In addition, it does not affect the design of the container or label. In addition, by writing an information code at the final stage of product manufacture, it is possible to deal with a case where time-limited information is provided in a timely manner. Furthermore, by making the information code a two-dimensional code, even if the lid has a small area, sufficient information can be provided in that space.

  Hereinafter, although this invention is demonstrated in detail, showing embodiment, this invention is limited to these description and is not interpreted. Hereinafter, the lid with the information code and the manufacturing method thereof will be described with reference to FIGS.

  The lid with an information code of this embodiment is a lid of a container for closing a container body for accommodating the contents, and an information code is written on the top surface of the lid.

  This embodiment will be described with a lid 100 with an information code shown in FIG. A lid 100 with an information code is a schematic diagram showing one embodiment of the present embodiment. The lid 100 with the information code is an example when combined with the container body 11 (indicated by a dotted line in FIG. 1). The lid 100 with an information code has a flat top surface 1, a side wall 2, and an information code 3 written on the top surface 1. The lid 100 with the information code is screwed into the mouth portion 12 of the container body 11 to close the container body 11.

The lid of the lid 100 with the information code closes the container body 11 for storing the contents. The configuration of the lid is not particularly limited, but it is essential to have the top surface 1 .

  The top surface 1 which is a part of the lid 100 with the information code is preferably flat. Here, “flat” does not mean that there is no unevenness according to the wording, but the flatness is such that the information code 3 printed or pasted on the top surface 1 can be read by a reader (not shown) of the information code 3. Is enough.

  Here, the reader is a device that reads information recorded in the information code 3, and may be a mobile phone, a barcode reader, a mobile terminal, a personal computer, or the like.

  The shape of the lid 100 with the information code may be, for example, a screw cap used for a PET bottle or a crown or ring-pull type.

  The material of the lid 100 with the information code is not particularly limited, but may be, for example, plastic, metal, glass, or paper. When lid 100 with information code is made of plastic, PE (polyethylene resin), PP (polypropylene resin), polystyrene resin, cycloolefin copolymer resin, PET (polyethylene terephthalate resin), polyethylene naphthalate resin, ethylene-vinyl alcohol copolymer resin , Poly-4-methylpentene-1 resin, polymethyl methacrylate resin, acrylonitrile resin, polyvinyl chloride resin, polyvinylidene chloride resin, acrylonitrile / styrene resin, acrylonitrile / butadiene / styrene resin, polyamide resin, polyamideimide resin, polyacetal Resin, polycarbonate resin, polybutylene terephthalate resin, ionomer resin, polysulfone resin, tetrafluoroethylene resin, nylon 6, nylon 66 and MXD Nylon and the like. Of these, polyolefins such as PET, PP, and PE, and nylons such as nylon 66 are preferable.

  When the material is glass, but not limited, soda lime glass is suitable. When the material is a metal, although not limited, aluminum, steel, or the like is preferable. For example, it may be a crown or a heat fusion lid made of a metal / resin laminate.

  In this embodiment, the container main body 11 is for accommodating the contents, and the shape of the container main body 11 may be any cross-sectional shape. For example, it may be a bottle shape, a box shape, a cup shape, a bag shape, a pouch shape, a cylindrical shape, a quadrangular prism shape, or a polygonal prism shape. The size of the mouth of the container body 11 may be a wide mouth or a narrow mouth.

  The material of the container main body 11 is not particularly limited, but may be plastic as well as the material of the lid 100 with the information code, and may be glass, metal, or paper. The material of the container body 11 may be the same as or different from the material of the lid 100 with the information code.

  The contents include, for example, fruit drinks, soft drinks, coffee, tea, tea, beer, sparkling liquor, drinks such as sake, Western liquor, fruit liquor, foods such as jelly, chewing gum, dairy products, or seasonings good. Furthermore, it may be a pharmaceutical product such as a tablet or powder.

The information code 3 is obtained by coding product information or the like attached to a normal product and provided to a consumer. Information code 3 in the present embodiment, Ri Oh a two-dimensional code does not include a one-dimensional bar code.

The one-dimensional bar code, encodes the information, which is that of the encoded symbols by the array of bars and spaces, for example, Jan, Code39, Nw-7 , Code128, ITF, Ru standards der the UPC such .

  In the present embodiment, a two-dimensional code is a symbol in which information is encoded in two dimensions in the X direction and the Y direction, whereas a one-dimensional barcode is computerized in the X direction (one dimension). . The two-dimensional code may be a standard such as Code 49, PDF 417, Micro PDF 417, etc., which is a stack type two-dimensional code in which barcodes are stacked, and is a matrix type two-dimensional code in which black stones are placed on the grid of a board. A certain standard such as MaxiCode, VeriCode, QRCode, DataMatrix, AztecCode, or the like may be used. Further, when these standards are improved in the future or a new standard is developed, the standard may be used.

The information encoded in the information code 3 includes on-time information as essential. The on-time information is information including, for example, campaign information such as a campaign with a prize provided by a company for consumers. Information encoded in the information encoding 3, in addition to the on-time information, handling of goods, description of goods, the price of food, manufacturing date, expiration date, product number, also include the product information of raw materials In addition, company information such as a manufacturer company name and a distributor company name, store information, and a product history such as a recycling status may be included.

  FIG. 2 is a schematic view of the lid 100 with the information code as viewed from above. Since the information code 3 is written on the flat top surface 1, the information code 3 itself is also flat. The information code 3 has a size that fits within the area of the top surface 1. Note that the information code 3 in the present embodiment may be written in substantially the entire area of the top surface 1 as long as it falls within the area of the top surface 1, and the information code 3 is sufficiently larger than the area of the top surface 1. May be written at any position on the top surface 1.

  In FIG. 2, the information code 3 is a QRCode which is a two-dimensional code. There are several types of QRCode models, but the model shown in FIG. 2 is a micro QRCode. The micro QRCode shown in FIG. 2 is an image and does not conform to an actual standard. The micro QRCode includes a black square-shaped cell 4a which is a minimum unit of a code, a white square-shaped cell 4b, a data cell 5 into which a group of these is written, a cut-out symbol 6 which is a position detection pattern, and a timing. The pattern 7, separator 8, format information 9, margin 10, and the like are included. In the micro QRCode, the information code 3 can be made extremely small by using one place where the other QRCode models have three cut-out symbols 6. By using such an information code 3, the information code 3 can be written on a lid having a relatively small top surface 1, for example, a pouch container.

  The information code 3 of the present embodiment may be written on the top surface 1 by printing such as ink jet printing, branding, marking, electrostatic printing, or may be written on the top surface 1 by sticking or other methods. The information code 3 in FIG. 2 is an example written on the top surface 1 by printing.

  In the case of printing on the top surface 1 by printing, when the lid 100 with the information code is recycled, it is possible to apply the paint again to the lid 100 with the information code and print again from there. When it is marked on the top surface 1 by pasting, it can be peeled off and then pasted again when recycling.

In the lid 100 with an information code in this embodiment, the information code 3 is the information code 3 written after the container body 11 is closed or just before the container body 11 is closed . Thus, by writing the information code 3 at the final stage of manufacturing the product, the information code 3 can be used as on-time information. The information code 3 written in this way is preferably printed at high speed like ink jet printing.

  Moreover, since the lid 100 with an information code in this embodiment writes the information code 3 on the flat top surface 1, the information code 3 is mechanically easy to read. If the information code 3 is written on the outer side wall of the container main body 11 and the cross-sectional shape of the container main body 11 is, for example, a circle, the end of the information code 3 is on the reading surface of the information code 3 reader due to the curvature thereof. On the other hand, since it has distortion, the reading accuracy is lowered. In addition, when the container body 11 is flexible like a pouch container, the information code 3 is distorted, so that the reading accuracy is lowered. On the other hand, in this embodiment, since the information code 3 is written on the flat top surface 1, the information code 3 can be flattened and high reading accuracy can be realized. In addition, the lid 100 with an information code according to the present embodiment is made of a material such as plastic, metal, glass and the like, and is structurally smaller than the container body 11, so that distortion is small and high reading accuracy can be realized.

  In the lid 100 with the information code in the present embodiment, the information code 3 is written on the top surface 1 on which the dirt is difficult to adhere, and therefore the information code 3 is hardly stained. If the information code 3 is written on the outer side wall of the container main body 11, the dealer or the consumer holds the container main body 11 in the distribution process from the time of manufacture until the consumer purchases, and the information code 3 is contaminated. There is a case. Also, in the distribution process, a plurality of containers are packed in a single box, and displayed at the store so that the plurality of containers are in contact with each other. In such a case, the information code 3 may be scraped or peeled off or dirt may be attached due to contact with other containers. Since the information code 3 is data encoded in the black and white cell 4, the reader recognizes that the dirt is the black cell 4a, and a part of the information code 3 that has been cut off is white. The cell 4b may be recognized and information may be erroneously detected and cannot be read. On the other hand, in this embodiment, since the information code 3 is written on the top surface 1, the possibility of being touched by a trader or a consumer during the distribution process is low. Further, in the packaging of containers and the display in stores, it is unlikely that another container is stacked on the top surface 1 of the lid 100 with the information code. Accordingly, it is possible to reduce the possibility that dirt is hardly attached to the information code 3 and the information is erroneously detected and cannot be read.

  In addition, since the lid 100 with the information code in the present embodiment has the information code 3 written on the top surface 1, it does not impair the aesthetics of the container or label design. The container main body 11 and the shrink film covering the container main body 11 are usually designed on the outer side wall of the container main body 11 in order to urge consumers to purchase. In addition, a trademark is usually applied to the front surface of the container body 11, and a product description, component display, and the like are written on the front surface of the container body 11. In addition to the front of the container body 11, a one-dimensional barcode or two-dimensional code encoding product information such as a product price and a product number is written. This product description, component display, etc., one-dimensional barcode, and two-dimensional code are not integrated with the design or trademark (hereinafter referred to as “design etc.”), and the aesthetics of the design etc. are impaired. . This is particularly noticeable when the size of the product is small. On the other hand, in this embodiment, when product information such as product description, component display, product price, product number, etc. is encoded in the information code 3, There is no loss of aesthetics such as the design.

Next, a method for manufacturing the lid with information code 100 according to the present embodiment will be described. The manufacturing method of the lid 100 with an information code according to the present embodiment includes a step of writing an information code on the top surface of the lid of the container at the final stage of manufacturing the product, and the on-time information is encoded as the information code 2 Write the dimension code. The process of writing the information code at the final stage of manufacturing the product includes a first manufacturing method in which the information code is given after the lid is attached and a second manufacturing method in which the information code is given before the lid is attached. is there. First, the first manufacturing method will be described. FIG. 3 shows an example of the manufacturing flow of the first manufacturing method of the lid with information code, which includes a lid mounting step (step S2) and an information code applying step (step S3). In addition to this, the lid manufacturing process (step S1) will be described.

  In the lid manufacturing process (step S1), a lid before applying the information code, that is, a normal lid is manufactured. When the lid is made of plastic, the plastic material pellets described above are prepared. A lid is obtained by molding the pellets using an injection molding machine or an extrusion molding machine. In addition, the shaping | molding method described at this process is an example, Other methods may be sufficient. When the lid is made of metal or glass, each is performed by ordinary metal processing and glass molding.

  In the lid attaching step (step S2), the contents are accommodated in the container main body in the content accommodating step shown in FIG. 3, and the lid manufactured in the lid manufacturing step (step S1) is attached to the container main body and tightly covered. If the lid is a screw cap, the side wall of the lid can be gripped, the head holding the lid can be lowered while rotating, and the lid can be tightened. If the lid is a roll-on type, the container body It is good also as a system which puts a lid | cover on the mouth part of this, and screw-forms with a screw roller according to the screw | thread of a mouth part, and is mounted | worn. The lid mounting method described in this step is an example, and other methods may be used.

  In the information code providing step (step S3), an information code is written on the top surface of the lid after the lid is tightly closed. Here, after the lid is closed, it is during the manufacturing process after the lid is closed and before the container after the lid is packed.

  The method of writing the information code may be performed by ink jet printing, or a sticker printed with the information code may be attached. As other methods, it may be a branding, engraving, electrostatic printing, laser marking or the like. Further, in the above-described lid mounting step (step S2), the transfer film with the information code written on the top surface may be pressed and transferred using the operation of applying pressure to the top surface when mounting the lid. good.

  The information code described in the information code applying step (step S3) and the information encoded in the information code are as described above.

  In the information code providing step (step S3) in the present embodiment, the information code is written on the top surface, so that it is easy to write the information code regardless of the shape of the cross section of the container body. If an information code is written on the outer side wall of the container main body, the manufacturing apparatus for applying the information code requires a container holding function and a holding jig according to the cross-sectional shape of the container main body. On the other hand, in the information code provision process (step S3) of this embodiment, since the information code is written on the top surface of the lid, the manufacturing apparatus does not need a holding function corresponding to the cross-sectional shape of the container body, and has a wide range. Can be easily applied to any kind of container.

  In the information code applying step (step S3) in the present embodiment, since the information code is written on the top surface, the manufacturing apparatus for applying the information code does not require a detection sensor or a positioning mechanism for applying the information code to the container body. And Suppose that an information code is written on the outer side wall of the container body. When the cross-sectional shape of the container body is a polygonal shape, it is necessary to print at a predetermined position (hereinafter referred to as “predetermined position”) on a predetermined surface of the outer side wall. The device to be closed (hereinafter referred to as “manufacturing device”) must hold the container body and detect a predetermined position for printing the information code. Therefore, the manufacturing apparatus requires a sensor for detecting a predetermined position and a container body positioning mechanism. On the other hand, in the information code provision process (step S3) of this embodiment, the information code may be written at any angle with respect to the top surface, and the above-described sensor and the container body positioning mechanism are not required. The manufacturing process can be simplified and the manufacturing apparatus can be made inexpensive.

  In the information code provision process (step S3) in the present embodiment, the information code is written after the container body is closed, thereby providing on-time information to the consumer. For example, when a lid manufacturer assigns an information code and the beverage manufacturer stores the contents in the container body, closes the lid, and ships, there is a period from the provision of the information code to shipping, and the latest information is consumed by the consumer. Can not be provided. On the other hand, since the information code provision process (step S3) in this embodiment is performed at the final stage of manufacture of the container main body containing the contents, on-time information can always be provided.

  In the information code provision step (step S3) in the present embodiment, the information code is written after the container body is closed, so that the stock of the lid with the information code is not generated. Manufacturing companies that house the contents in the container body have a large amount of shrink film (hereinafter referred to as “container body etc.”) covering the container body and the container body in the manufacturing company in order to efficiently distribute the product to the market. Must be stocked. Usually, an information code is already printed on the container body or the like. Therefore, when a new campaign is planned, the stocked container body and the like are discarded. On the other hand, in the information code providing step (step S3) in the present embodiment, the lid with the information code is formed by using the lid with the information code in which the information code is written at the final stage of manufacturing the container body containing the contents. Does not generate stock.

  Next, a second manufacturing method (not shown) will be described. In the second manufacturing method, the top surface of the container lid that closes the container body is directed in a predetermined direction, and then the lid is supplied to a capping machine that tightens the container body containing the contents, Write an information code on the top of the lid.

  In the second manufacturing method, the lid before the information code is written is manufactured as in the lid manufacturing process (step S1) of the first manufacturing method. An information code is written on the lid in the same manner as in the information code applying step (step S3) of the first manufacturing method while the container body containing the contents is being supplied to the capping machine for fastening the lid. Thereafter, the lid with the information code is supplied to the capping machine.

  Here, the capping machine is a device that attaches a lid, which is supplied to the cap supply hopper and flows through the cap supply line, to the container body containing the contents, and tightens the lid. When the lid is a screw cap, it may be a device that grips the side wall of the lid, and the head holding the lid descends while rotating, and tightens the lid. If the lid is a roll-on type, the mouth of the container body It is also possible to use a device in which a cover is put on and then formed with a screw roller in accordance with the screw of the mouth and attached.

  By setting it as the 2nd manufacturing method, the manufacturing method of the lid | cover with an information code which concerns on this embodiment is applicable also in manufacturing processes, such as food and drink using a high-speed capping machine. In this case, in order to suppress a decrease in the flow speed of the cap supply line, the information code is preferably obtained by high-speed printing such as inkjet printing.

  Also in the second manufacturing method, the same effects as in the first manufacturing method can be obtained.

The use method of the present invention will be described by taking the lid 100 with the information code of FIG. 1 manufactured by the manufacturing method of the present embodiment as an example. The lid 100 with an information code is obtained by writing an information code on the top surface 1 of the lid. Therefore, when a consumer purchases a product, it is possible to obtain various product information by reading the information code 3 written on the top surface 1 of the lid 100 with the information code with a reader of the information code 3 such as a mobile phone. it can. Moreover, after a consumer purchases a product, the information code 3 of the lid 100 with an information code can be similarly read to obtain on-time information such as campaign information. Further, a trader in the distribution process or a store clerk reads the information code 3 of the lid 100 with the information code with a reader such as a barcode reader to obtain product information such as the shipping date of the product. Can do.

  The lid with an information code according to the present invention can be used as a lid for various containers such as a lid for a container for food and drink and a lid for a container for pharmaceuticals.
