Description

  The present invention relates to an improvement in the method of packaging for frying. Manufacturers can wrap the fried foods one by one with plain film, and then bind the bundles with a heat-weldable film printed with a label that conforms to laws and regulations. Can be easily inspected before wrapping, and consumers can avoid storing it in an open state, so they can always eat freshly fried freshly fried food, and it can rot. The amount of trash can be reduced.

  Since the frying is necessary for the packaging, the marking based on the laws and regulations is printed on the packaging film for the commonly-fried frying products. That is, as shown in FIG. 4, when the fried product 5 is packaged with the packaging film 5 a, the surface of the fried products 6, 6, 6 is hidden in the display prints 5 b, 5 c, and the mixed foreign matter cannot be found. It had the problem that there were many possibilities.

  In addition, if it is also the fried product 5 in which a plurality of fried items 6, 6 and 6 are packaged, the overlapping part of the fried items 6 and 6 will inevitably disappear, and if a foreign object is mixed there, it will be discovered It was extremely difficult to do.

Furthermore, when using only a few fried products 5 containing a plurality of fried products 5 and storing the rest in a refrigerator or the like, the packaging film 5a had to be stored in an opened state, so the odor was transferred to other foods. Or the odor was transferred from other foods, and the frying itself and other foods were adversely affected. Naturally, when stored in an opened state, it was easily contaminated with microorganisms, so the storage stability was also poor.
Japanese Patent Laid-Open No. 06-189705

  Ensuring food safety and security is the mission of food companies. Daily products such as fried goods were sold in retail stores in the old days, but now when large retailers sell them, they are all sold in film-wrapped form. It was.

  However, packaging with film complies with regulations such as the JAS Law and Food Sanitation Law, so it is necessary to display product names and various labels on the film surface, and the manufacturer or consumer confirms the entire surface of the frying itself inside the film. It became difficult to do.

  In particular, consumer demand for quality has increased, and not only foreign objects such as various kinds of garbage or insects, but even fried debris of 1 mm or less, which was not the cause of complaints before, has been pointed out as a foreign object. The burden of is increasing.

  Usually, the manufacturer visually inspects the fried food before packaging, applies the passed product to an automatic packaging machine, and takes measures against contamination by visual inspection after packaging.

  In addition, since the surface of the fried oil is wet with oil, there is a possibility of secondary contamination in the inspection of both the image apparatus and the human hand, and effective inspection is very difficult. And the inspection after film packaging was hardly effective.

  In addition, a product that is packed with a plurality of fried products in one film that occupies the mainstream presents a serious problem for consumers in addition to the inspection problem of the manufacturer. That is, a consumer who purchases such a product usually uses the required number of sheets at the time of use, and usually stores it in a refrigerator or a freezer for later use.

  However, once it is opened, it is known that frying will give off a unique odor and transfer unpleasant odors to ice and other foods stored in refrigerators and freezers. Deodorizers are put in place to prevent these problems.

  In addition, the remaining frying after the use of a part is stored at a low temperature in a refrigerator, etc., but when using a part of the frying, there is a high possibility that it will be microbially contaminated from the fingers, etc. Even if it is stored in a refrigerator such as a refrigerator, the number of microorganisms will be considerable in 3 days, so it is possible to guarantee the safety for a long time without opening, but it is very much guaranteed for those that have been opened difficult.

  In this way, there have been problems on both sides, such as efforts to ensure the safety and security of manufacturers and increased burden on consumers. The problem of odor transfer in the refrigerator and the shelf life of the consumer can be dealt with by packaging the fried chicken one by one, but the burden on the consumer is still reduced with the multi-package products with the highest sales volume. Not.

  For this reason, a method of bundling individually packaged products and packaging them with a large bag with a display can be easily considered, but the manufacturing method becomes complicated, the cost increases, and the economic burden on the consumer increases. Moreover, it is not preferable from the viewpoint of environmental protection, such as an increase in the amount of garbage after use.

  A relatively simple method is to combine multiple individual packages with belt film or rubber bands, but it is expected that they will be dropped during the display or intentionally removed. The surface must be printed film with various indications, and the problems of automation of inspection and accuracy improvement cannot be solved at all.

  Therefore, the present invention makes it possible for manufacturers to easily and reliably carry out visual inspection work for safety and security, and does not place a burden on consumers in terms of storage and hygiene, and always provides fresh fresh frying. An object of the present invention is to provide a method for packaging fried chicken that can be provided.

  In order to achieve the above object, the inventors have conducted intensive research, individually wrapping the fried oil pulled up from the oil tank one by one with a plain transparent film, passing through a foreign substance inspection device such as an image device or visually inspecting both sides. After that, the target number of sheets is wound in a strip with a film that has been labeled in compliance with laws and regulations, and the film used for the strip and the film individually wrapped with fried oil are welded with an appropriate heat source to produce an integrated product. I found out that various problems can be solved.

  Since the frying produced in this way is immediately packaged one by one with a transparent individual packaging film, the subsequent inspection work is performed in a very hygienic manner, and foreign matter inspection and individual packaging on the frying front and back, which could not be carried out conventionally, can be performed. There is no need for inspection of foreign matter under the film printing surface.

  For this reason, not only high-precision visual inspection but also machine inspection using an image processing apparatus or the like is possible, and the quality of the frying that is shipped is dramatically improved. Further, since a plurality of sheets are not wrapped in one individual packaging film, there is no need to worry about foreign matters mixed in the overlapped portion.

  Furthermore, the peculiar odor in the refrigerator or freezer caused by the remaining frying when a part is used in a home where a plurality of sheets have been purchased is also solved, and it is not subject to microbial contamination, thereby significantly reducing the burden on the consumer.

  Furthermore, since all the products are plain individual packaging film packages at the oil frying production factory, and products can be produced with combinations of other types of sheets simply by setting the stacker, a huge display printing for each item as before It is no longer necessary to prepare the individual packaging film, and it is freed from the complexity of the production line and the film inventory management, and the industrial profit is great from the viewpoint of production management and resource saving.

  Below, based on an accompanying drawing, the packaging method of the frying which is this invention is demonstrated in detail. FIG. 1 is a perspective view of the fried food and the band wrapped in a plain film before banding, FIG. 2 is a perspective view of the fried food bundled and banded, and FIG. 3 is a perspective view of the fried food wrapped in a plain film.

  As shown in FIG. 1, the packaging method for fried oil according to the present invention is provided with a display 2a corresponding to the legal regulations for individually wrapped fried foods 1, 1, 1,. The display band 2 is used for packaging.

  In the fried packaging method according to the present invention, the fried 1b is first packaged one by one with the plain film 1a to be individually packaged fried 1. As a material of the plain film 1a for individual packaging used at this time, polypropylene or polyethylene terephthalate is preferable.

  Polyethylene and nylon cannot be used because they are not welded. In view of the strength of welding with the display strip 2, the efficiency during production, and the visibility during inspection, polypropylene is most desirable.

  Moreover, the material of the display strip 2 on which the display 2a corresponding to the regulations is printed may be any material as long as a heat-welding agent is applied to a synthetic resin film, but preferably chlorinated polypropylene and ethylene vinyl acetate. What applied the mixture to the synthetic resin film has good compatibility in terms of the welding temperature and the welding time.

  Next, as shown in FIG. 2, the individually packaged oil frying 1, 1, 1 in which the oil frying 1 b is packaged one by one with the plain film 1 a is bundled. At this time, the number of individually wrapped frying 1 to be bundled is not limited, and the number of sheets necessary for selling as a product such as three or five can be bundled.

  The welding of the plain film 1a of the individual wrapping 1 and the display strip 2 uses hot water, hot air or a heating plate, and can be applied to any part as long as it does not impair the printing of the printed part of the display 2a corresponding to the legal regulations. It is only necessary to heat and weld by a general method of pressure bonding after passing the individual wrapping and frying 1 which is the frying 1b wrapped in the plain film 1a through a commercially available banding machine and banding the display band 2.

  In addition, when bundling a plurality of individually packaged oil pumps 1, any commercially available stacking machine may be used. Then, after the display band 2 is applied, the product is completed by heating and welding in a general pressure bonding method.

  In the state shown in FIG. 2, a display band 2 made of a polypropylene film coated with a mixture of chlorinated polypropylene and ethylene vinyl acetate is hung on a bundle of a plurality of individually packaged oil fryings 1.

  Bonding both ends of the display strip 2 at the bottom of the individual packaged frying 1 individually wrapped with the fried chicken, and fixing it first, then touching it with a 95 degree iron plate from the side, the plain film of the individual packaged frying 1 in 2 seconds 1a and the display band 2 are welded at the bonding portion 3.

  When using the fried food packaged by the fried food packaging method according to the present invention in which a plurality of individually wrapped fried food products 1 as shown in FIG. Pull out and use the individual packaged oil pump 1. FIG. 3 shows a drawing of the individually packaged frying 1 that has been pulled out.

  As shown in FIG. 3, the individual packaging oil frying 1 pulled out from the package in which the individual packaging oil frying 1 and the display strip 2 are welded appears on the side surface of the bonding portion 4 with the display strip 2, but the plain film 1 a Since it is not torn, it is very hygienic and convenient for storage.

  In the following, the conventional packaging method for packaging a plurality of fried oysters in one bag in each aspect of safety, hygiene, preservation, etc. will be compared with the packaging method for fried chicken according to the present invention.

Comparative Example 1

  Randomly put a foreign object on the frying box, bundle it in multiple sheets, package it in a bag and inspect it, and there are foreign objects on the top and bottom surfaces of the frying and the side of each packaged frying. Although things could be found by inspection, foreign matter could not be found in all other parts.

  On the other hand, when inspections were carried out on products that were wrapped in the same fried foods one by one with printed films, some foreign matter could be found, but some foreign matter attached to the inside of the print or design could not be found.

  Similarly, when the individually packaged fried chicken 1 individually packaged with the plain film 1a used in the packaging method of the fried chicken according to the present invention was randomly collected with foreign matters, all foreign matters were found. In other words, the individually packaged frying 1 individually packaged with the plain film 1a by the frying packaging method of the present invention is superior in terms of safety and the like.

Comparative Example 2

  I put a cup filled with water in the refrigerator, opened a bag of fried rice in multiple bags, left it next to it for a day, and drank a cup of water. In addition, when a similar frying was left in the freezer and drinking water with ice made in that state, a peculiar odor was felt.

  However, when the same experiment was conducted with the fried food packaged by the fried food packaging method according to the present invention in which the individually wrapped fried food 1 was bundled by welding the display band 2, it was not necessary to leave it in an unsealed state, so that the odor was transferred. There was no peculiar smell in water and ice.

Comparative Example 3

  Opening a bag of frying in multiple sheets, using a portion of it and storing it at a temperature of 10 degrees for 5 days, and conducting a microbiological examination. There were more than 300,000 microorganisms per gram.

  On the other hand, even when only the necessary number of sheets is used in the individually packaged frying 1 according to the frying packaging method of the present invention, microorganisms were not recognized because the frying itself was not touched. Therefore, it is much better in terms of hygiene than the conventional frying packaging method.

Comparative Example 4

  In the past, it was necessary to prepare a huge amount of individually printed film for display and printed for each item, and the stock film that occurred when the product was replaced had to be discarded. This led to simplification of production management and resource saving.

Comparative Example 5

  Try to implement a packaging form that bundles and wraps multiple individual wrappings 1 by using the friction between the strip and the wrapping film, and slides the individual wrapping 1 into polyethylene, nylon and polypropylene. As a result of banding with each of the coated coating materials, it cannot be fixed sufficiently, and adults can pull it off just by pulling it lightly. Became.

  In addition, although the individual wrapping frying 1 is bundled and banded with cellophane tape and vinyl tape, the bundled individual wrapping frying 1 can be fixed, but the strength of bonding the tape and the plain film 1a is too strong. Therefore, there is a problem that it is difficult to pull or tears from the bonded portion 4 of the plain film.

  Then, what apply | coated the mixture of the chlorinated polypropylene and ethylene vinyl acetate to the belt | band | zone was used, and the part of the adhesion part 3 of the display band 2 and the adhesion part 4 of the plain film 1a was heated at 95 degreeC for 2 second, and was adhere | attached.

  As a result, even if each individual wrapping frying 1 is spring-weighted and pulled with a strength of 500 g, it remains stable while being fixed to the display band 2, and even if the individual wrapping frying 1 is pulled out one by one, the plain film 1a is The unpacked individual wrapping 1 that was pulled out remained fixed to the display band 2 and did not fall apart.

It is the perspective view of the fried and the band wrapped in the plain film before banding. FIG. It is a perspective view of the fried food wrapped with the plain film. It is a perspective view of the fried food packaged with the conventional packaging method.
