Description

  The present invention relates to a packaging bag in which a piece such as a cutting bag or a round bag is contained in an individual packing bag.

  Conventionally, packaging bags sold at grocery stores and supermarkets are outer packaging bags that can seal together multiple pieces of oxygen contained in individual packaging bags and oxygen scavengers. Many of the bags are sold in a sealed state in an outer bag of a size that can be accommodated multiple times, but individual packaging bags containing these pieces have low gas barrier properties. If it is opened, it will be exposed to a large amount of air (oxygen and moisture) and cannot be stored until the expiration date displayed on the outer packaging bag. Store it in the refrigerator and eat it as soon as possible. It has to be.

  Originally, it is ideal that even if the outer packaging bag is opened, the individual packaging bags contained in the individual packaging bag in this outer packaging bag can be stored until the expiration date without being affected by the outside. It is.

  However, a pillow packaging bag is generally used as the individual packaging bag for storing the splinter. This pillow packaging bag has a very low probability, but a sealing failure occurs during sealing, and a leak hole is formed. (Pinhole) may occur, and if the packaging bag of the individual packaging bag with this leak hole is shipped, air (oxygen) from the leak hole into the individual packaging bag even within the expiration date. And water) will easily enter and become a problem.

  In order to prevent this, a pinhole inspection for inspecting the occurrence of leakage holes may be performed at the time of shipment. However, since this pinhole inspection is very difficult, it is actually an individual package. When the outer packaging bag is opened, it is stored in the outer packaging bag with extremely high airtightness so that the outer packaging bag can be stored in an unopened state until the expiration date. It cannot be stored until the expiration date displayed on the packaging bag, and must be stored in the refrigerator and eaten as soon as possible.

  The present invention makes it possible to inspect whether or not there is a leak hole (pinhole) in the individual packaging bag containing the piece very easily. The purpose of the present invention is to provide a packaging container that enables the expiration date management of the chip in units.

  The gist of the present invention will be described with reference to the accompanying drawings.

It is a top view which shows the back surface of the individual packaging bag of a present Example. It is explanatory drawing which shows the leak hole which arises in the individual packaging bag of a present Example. It is the schematic which shows the inspection apparatus of a present Example.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  In the present invention, the individual packaging bag 3 containing the flange 1 and the oxygen scavenger 2 is filled and sealed with helium gas together with an antioxidant gas mainly composed of an inert gas. When the filling gas becomes a bulging shape, and the individual packaging bag 3 having the bulging shape has a sealing failure or a leak hole 4 such as a pinhole, the bulging shaped individual packaging bag 3 is externally attached. Since the helium gas is discharged from the leak hole 4 by pressing, the helium detector 5 detects the helium discharged from the leak hole 4 by pressing the individual package bag 3 so that the individual package bag can be easily used. It is possible to detect that the leak hole 4 is generated in 3.

  That is, the present invention fills the individual packaging bag 3 by filling the individual packaging bag 3 containing the piece 1 and the oxygen scavenger 2 with helium gas together with an antioxidant gas mainly composed of an inert gas. If the helium detector 5 detects helium gas when the bulging individual packaging bag 3 is pressed in the inspection process and formed into a shape, it is determined that a leak hole 4 has occurred in the individual packaging bag 3, Even if the individual packaging bag 3 is pressed, if the helium detector 5 does not detect the helium gas, it can be determined that the leakage hole 4 is not formed in the individual packaging bag 3. It is possible to perform a pinhole inspection as to whether or not the leak hole 4 has occurred.

Accordingly, the present invention is to ship only such make pinhole inspection for all individual package cake 13, which is possible holes 4 leaks into individual packaging bag 3 does not occur is confirmed, the outer Even if the packaging bag 6 is opened and the individual packaging bag 13 in the outer packaging bag 6 is exposed to the air, air (oxygen or moisture) enters from the outside into the individual packaging bag 3 containing the bag 1. Therefore, the condition in which mold is generated is not established in the individual packaging bag 3, so that the epoch 1 in the individual packaging bag 3 can be stored until the expiration date.

  In addition, since the present invention accommodates the oxygen scavenger 2 in the individual packaging bag 3 together with the piece 1, the oxygen scavenger 2 absorbs and removes oxygen remaining in the individual packaging bag 3 when sealed. Since the oxygen is not present in the individual packaging bag 3 and further, the oxygen scavenger 2 absorbs and removes a slight amount of oxygen that permeates through the individual packaging bag 3 from the outside. Oxygen is reduced as much as possible, and it becomes a packaging container that is less prone to mold and can be stored for a long time.

Furthermore, since the helium gas filled in the individual packaging bag 3 gradually passes through the individual packaging bag 3 and flows out to the outside as time passes, the individual packaging bag 3 is used to remove residual oxygen. The bulging shape is relaxed by the outflow of helium gas, and the individual packaging basket 13 is formed with good appearance.

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

This embodiment, as shown in FIG. 1, the individual packaging cake 13 containing a rice cake pieces 1 into individual packaging bag 3, as shown in FIG. 2, packaging which is formed by several double sealed in an outer packaging bag 6 It is a spear.

In addition, the individual packaging bag 13 of the present embodiment puts the piece 1 and the oxygen scavenger 2 in the individual packaging bag 3, and an antioxidant gas mainly composed of an inert gas in the individual packaging bag 3. And the individual packaging bag 13 filled with helium gas and sealed, and the helium gas is swelled by the filled gas when a leak hole 4 is formed in the sealed individual packaging bag 3. This is a packaging bag set to a filling amount in which an amount detectable by the helium detector 5 is discharged from the leak hole 4 by pressing the sealed individual packaging bag 3 from the outside.

  More specifically, the scissors piece 1 of the present embodiment is specifically a small scissor such as a cut scissor or a round scissors.

  Further, the oxygen scavenger 2 accommodated in the individual packaging bag 3 together with the piece 1 specifically employs an oxygen scavenger with iron or iron oxide as a reaction main agent, and the surface side of the individual packaging bag 3 It is set as the structure provided in the affixed state on the inner surface.

  The individual packaging bag 3 that accommodates the piece 1 and the oxygen scavenger 2 is made of a synthetic resin film having a high gas barrier property, and contains an inert gas filled in the individual packaging bag 3 described later as a main component. The anti-oxidation gas is prevented from permeating and flowing out of the individual packaging bag 3, and air (oxygen and moisture) is prevented from penetrating into the individual packaging bag 3 from the outside.

Specifically, in this embodiment, the individual packaging bag 3 is configured such that the gas barrier property, that is, the oxygen permeability is 1 ml / m ² · day · MPa or less. It is composed of a three-layered individual wrapping bag 3 using linear low density polyethylene for the second layer, polyethylene for the second layer and nylon for the third layer. Is configured to shut off.

  Moreover, it is set as the structure which described the expiration date 7 of the accommodated piece 1 in the outer surface of the individual packaging bag 3 of a present Example, specifically, the surface.

  Furthermore, as shown in FIG. 3, the individual packaging bag 3 of the present embodiment is configured to employ a pillow packaging bag.

  In the individual packaging bag 3 configured in this manner, the above-described scissors 1 and the oxygen scavenger 2 are accommodated, and an antioxidant gas mainly composed of an inert gas and helium gas are contained in the individual packaging bag 3. Filled configuration.

  This individual packaging bag 3 is filled with an antioxidant gas mainly composed of an inert gas for the purpose of reducing the presence of oxygen in the individual packaging bag 3 as much as possible. 3 is filled for the purpose of use when inspecting the presence or absence of the occurrence of the leak hole 4 due to poor sealing that occurs when the opening 8 of the three is sealed.

  The filling amount of the antioxidant gas mainly composed of the inert gas and the helium gas into the individual packaging bag 3 is such that the individual packaging bag 3 that contains and seals the piece 1 and the oxygen scavenger 2 The amount of bulging shape is set by the gas.

  Furthermore, in other words, the filling amount of the antioxidant gas and the helium gas into the individual packaging bags 3 is such that after the individual packaging bags 3 are sealed one after another, the individual packaging bags 3 that are bulged by this sealing are used. When the leak hole 4 is generated in the sealed individual packaging bag 3 when pressed from the outside, the amount of helium gas that can be detected by the helium detector 5 is set to be discharged.

  Specifically, the filling amount of the antioxidant gas mainly composed of the inert gas filled in the individual packaging bag 3 is the residual oxygen gas in the individual packaging bag 3 immediately after the individual packaging bag 3 is sealed. The amount is set to 9 vol% or less with respect to the total gas capacity in the individual packaging bag 3.

  Further, the antioxidant gas mainly composed of an inert gas according to the present embodiment is an antioxidant gas mainly composed of an inert gas such as nitrogen gas or argon gas. Inexpensive nitrogen gas is used for the gas.

  The filling amount of the helium gas filled together with the antioxidant gas mainly composed of nitrogen gas is expanded by the filled gas when the leak hole 4 is formed in the sealed individual packaging bag 3. The amount that can be detected by the helium detector 5 is set to be discharged from the leak hole 4 by pressing the sealed individual packaging bag 3 from the outside, more specifically, the individual packaging bag 3. The amount is set to 1 vol% to 9 vol% with respect to the total gas capacity.

  In addition, as described above, the present embodiment employs a pillow packaging bag as the individual packaging bag 3, and this pillow packaging bag is used when the opening 8 is sealed as shown in FIG. Due to the effect of the level difference caused by the sticking part 9, there is a possibility that the leak hole 4 may be generated due to a seal failure although the probability is very low.

  Therefore, after sealing the individual packaging bag 3 as the pillow packaging bag, a pinhole inspection for confirming whether or not the leak hole 4 is generated in the sealed individual packaging bag 3 must be performed.

The inspection process for performing the pinhole inspection of the present embodiment will be described. In this inspection process, the individual packaging bag 3 has a bulging shape by being filled with an antioxidant gas mainly composed of nitrogen gas and helium gas. Whether or not the individual packaging bag 13 is conveyed into the inspection apparatus 10 and the individual packaging bag 3 is pressed from the outside in the inspection apparatus 10 so that the helium detector 5 attached to the inspection apparatus 10 detects helium gas. Thus, it is determined whether or not the leakage hole 4 is formed in the individual packaging bag 3.

  That is, when the leak hole 4 is formed in the individual packaging bag 3, the helium gas in the individual packaging bag 3 is discharged and diffused into the inspection device 10 when the individual packaging bag 3 is pressed. By detecting the helium gas diffused in the helium detector 5, it can be determined that the leak hole 4 is formed in the individual packaging bag 3, and the leak hole 4 is generated in the individual packaging bag 3. If not, the helium gas in the individual packaging bag 3 does not flow out of the individual packaging bag 3 even when the individual packaging bag 3 is pressed, so there is no helium gas in the inspection device 10, and thus the helium detector. No. 5 is an extremely simple inspection method that can determine that no leak hole 4 is formed in the individual packaging bag 3 because helium gas is not detected.

  Specifically, as shown in FIG. 5, the inspection apparatus 10 includes a belt conveyance mechanism 11 disposed above and below and a helium detector 5, and the belt conveyance mechanism 11 disposed above and below is viewed from above and below. By conveying the swelled individual packaging bag 3 while pressing it, if there is a leak hole 4 in the individual packaging bag 3, it is discharged when pressed from the gas suction part 12 provided in the middle of the conveyance. The helium gas is drawn into the helium detector 5 and the fact that the gas sucked by the helium detector 5 is recognized as helium gas is output to indicate that helium gas has been detected.

Thus, it is possible to perform the determining pinhole inspection for leakage hole 4 while being transported in the manufacturing process, it is possible to perform very fast and accurate pinhole inspection, all individual packaging produced It can perform total inspection against rice 13, whereby, since it is unnecessary to ship individual packaging mochi 13 two that is leaking hole 4 is generated in the individual package bag 3, a plurality accommodate individual package mochi 13 Even if the outer packaging bag 6 is opened and the individual packaging bag 13 in the outer packaging bag 6 is exposed to air, air (oxygen or moisture) enters the individual packaging bag 3 containing the bag 1 from the outside. Therefore, the condition for mold generation is not established in the individual packaging bag 3, and thus the epoch 1 in the individual packaging bag 3 can be stored until the expiration date.

  Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
