Description

[Technical Field]

[0001] The present invention relates to a package. [Background Art]

[0002] Conventionally, packages intended for long-term storage of an object while maintaining the quality of the object are known. For example, in the package disclosed in Patent Document 1, an object such as a high-humidity food, a liquid beverage, or a pharmaceutical product is sealed in an inner bag having an oxygen permeability equal to or higher than a predetermined value, and the inner bag and an oxygen scavenger are sealed in an outer bag. It is described that this enables long-term storage while maintaining the quality of an object whose quality is particularly likely to be degraded by oxygen. [Prior Art Literature] [Patent Literature]

[0003] [Patent Document 1] Japanese Unexamined Patent Publication No. Hei 5-319459 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] By the way, in recent years, with the trend toward BEV for automobiles, the discontinuation of production of old internal combustion engine components, for which demand continues in small quantities, has become one of the issues in corporate activities. This problem can be solved by producing a required quantity of automotive components and storing them for a long period of time.

[0005] However, in the package of Patent Document 1, for example, when automotive components including metal components are sealed in the inner bag, although quality degradation due to oxygen can be suppressed, there is a risk that quality degradation due to moisture may occur, such as rusting of the automotive components caused by moisture adhering to the automotive components or moisture (water vapor) present inside and outside the inner bag.

[0006] An object of the present invention is to provide a package that can be stored for a long time while maintaining the quality of automotive components. [Means for Solving the Problem]

[0007] The packaging according to the present invention comprises a resin inner bag (20), an oxygen absorber (51) and a dehydrating agent (52), and a high gas barrier bag (60). The inner bag is capable of storing an automobile part (10). The oxygen absorber and dehydrating agent are placed on the outside of the inner bag. The high gas barrier bag is formed in a bag shape such that its oxygen permeability and moisture permeability are below predetermined values, and is capable of enclosing the inner bag containing the automobile part, as well as the oxygen absorber and dehydrating agent. The inner bag has a specific functional section that allows the passage of gas while suppressing the passage of liquid.

[0008] In this invention, the intrusion of oxygen and moisture (water vapor) from the outside into the inside of the high gas barrier bag can be suppressed. Furthermore, oxygen and water vapor present inside the inner bag can pass through a specific functional section to the outside of the inner bag. The oxygen and water vapor that have passed to the outside of the inner bag are removed by the oxygen absorber and dehydrating agent inside the high gas barrier bag. As a result, the oxygen concentration and humidity inside the inner bag are reduced, which can suppress rusting of automotive parts stored in the inner bag, and can also suppress the oxidation of oil applied to automotive parts for rust prevention purposes.

[0009] Furthermore, in this invention, since the specific functional part can suppress the passage of liquid, it is possible to prevent oil applied to automotive parts from leaking out of the inner bag and adhering to the oxygen absorber and dehydrating agent. This suppresses the deterioration of the performance of the oxygen absorber and dehydrating agent. Therefore, long-term storage is possible while maintaining the quality of automotive parts.

[Figure 2] A schematic diagram showing a package according to a second embodiment and an automotive part contained therein. [Figure 3] A schematic diagram showing a package according to the third embodiment and an automotive part contained therein. [Figure 4] A schematic diagram showing a package according to the fourth embodiment and an automotive part contained therein. [Modes for carrying out the invention]

[0011] The following describes packaging according to several embodiments based on the drawings. In addition, substantially identical components in multiple embodiments are denoted by the same reference numerals, and their descriptions are omitted.

[0012] (First Embodiment) Figure 1 shows a packaging body according to the first embodiment and an automotive part stored therein. The packaging body 1 can be used, for example, for long-term storage of an automotive part 10. The automotive part 10 is, for example, a fuel injector capable of injecting high-pressure fuel into an internal combustion engine. The automotive part 10 includes metal parts such as a nozzle and a needle, and has a fuel supply port 11 for supplying high-pressure fuel, an injection port 12 for injecting fuel, an outlet 13 for discharging excess fuel, etc. In addition, oil used during performance testing may remain inside the automotive part 10, and rust-preventive oil may be applied to the outer wall of the automotive part 10.

[0013] The packaging body 1 comprises an inner bag 20, an oxygen absorber 51 and a dehydrating agent 52, and a high gas barrier bag 60. The inner bag 20 is formed in a rectangular bag shape from a resin such as nylon or polyethylene, which is a type of polyamide synthetic resin. Here, for example, if the inner bag 20 is made of nylon, the oxygen permeability (ml / m³) 2 The humidity (g / m²) is 30-120, and the moisture permeability (g / m²) is 30-120. 2 The day is 16. If the inner bag 20 is made of polyethylene, the oxygen permeability is 2000-5000 and the moisture permeability is 19.

[0014] The inner bag 20 has an open end 21 on a predetermined side. The inner bag 20 can store the automotive part 10 inside via the open end 21. Figure 1 shows the state in which the automotive part 10 is stored in the inner bag 20.

[0015] In this embodiment, the oxygen absorber 51 and the dehydrating agent 52 are provided integrally as the oxygen absorber moisture agent 50. The oxygen absorber moisture agent 50 (oxygen absorber 51, dehydrating agent 52) ​​is placed on the outside of the inner bag 20. The oxygen absorber moisture agent 50 (oxygen absorber 51) can absorb ambient oxygen through a chemical reaction. The oxygen absorber moisture agent 50 (dehydrating agent 52) ​​can absorb ambient moisture (humidity) through a chemical reaction. In addition, the oxygen absorber moisture agent 50 can absorb corrosive gases such as hydrogen sulfide, sulfur dioxide, hydrogen chloride, and ammonia through a chemical reaction. When a specified amount of the oxygen absorber moisture agent 50 is sealed in a suitable container, it is possible to reduce the oxygen concentration to 0.1% or less in about one day, the relative humidity to 10% or less in a few hours, and the hydrogen sulfide concentration to 1 ppm or less in a few hours.

[0016] The high gas barrier bag 60 is formed in a rectangular bag shape from, for example, multi-layer laminated aluminum foil, or a resin such as polyethylene terephthalate or polyethylene with a ceramic coating. For example, if the high gas barrier bag 60 is formed from multi-layer laminated aluminum foil, the oxygen permeability is less than 0.01 and the moisture permeability is less than 0.01. If the high gas barrier bag 60 is formed from a resin with a ceramic coating, the oxygen permeability is 0.5 and the moisture permeability is 1.5. In this way, the high gas barrier bag 60 is formed so that the oxygen permeability and moisture permeability are below predetermined values.

[0017] In the present embodiment, the specific functional portion 70 is an opening 71 formed in the inner bag 20. The opening 71 is formed at the open end 21 of the inner bag 20 at a position other than the seal portion 22 formed by joining opposing inner surfaces of the inner bag 20. Here, the seal portion 22 is formed by joining the opposing inner surfaces of the inner bag 20 by, for example, heat sealing (heat welding), an adhesive, a fitting structure, or the like after the automotive component 10 is housed in the inner bag 20. The specific functional portion 70 (the opening 71) allows passage of gas while suppressing passage of liquid. Therefore, oxygen and water vapor present inside the inner bag 20 can pass to the outside of the inner bag 20 via the specific functional portion 70 (the opening 71). On the other hand, oil detached from the automotive component 10 inside the inner bag 20 is suppressed from passing to the outside of the inner bag 20 via the specific functional portion 70 (the opening 71).

[0018] An inner diameter D1 of the opening 71 is smaller than a minimum outer diameter D2 of the automotive component 10 in the longitudinal direction. Therefore, the automotive component 10 can be suppressed from coming out of the inner bag 20 via the opening 71.

[0019] The high gas barrier bag 60 is capable of enclosing the inner bag 20 housing the automotive component 10 and a deoxidizing and dehumidifying agent 50 (a deoxidizing agent 51 and a dehumidifying agent 52). In the present embodiment, the inner bag 20 housing the automotive component 10 and the deoxidizing and dehumidifying agent 50 (the deoxidizing agent 51 and the dehumidifying agent 52) are put into the high gas barrier bag 60 through the open end 61, and the open end 61 is sealed by, for example, heat welding to hermetically seal the high gas barrier bag 60. Thereby, permeation of oxygen and moisture (humidity, water vapor) from the outside to the inside of the high gas barrier bag 60 can be suppressed, and the oxygen concentration and humidity in the high gas barrier bag 60 can be reduced to or below predetermined values by the deoxidizing and dehumidifying agent 50. In the present embodiment, since the specific functional portion 70 (the opening 71) is provided in the inner bag 20, oxygen and water vapor inside the inner bag 20 flow out to the outside of the inner bag 20 via the specific functional portion 70 (the opening 71) and are absorbed by the deoxidizing and dehumidifying agent 50 (the deoxidizing agent 51 and the dehumidifying agent 52). Thereby, the oxygen concentration and humidity inside the inner bag 20 can be maintained at or below predetermined values.

[0020] As described above, (1) the package 1 of the present embodiment includes a resin inner bag 20, an oxygen scavenger 51, a moisture scavenger 52, and a high gas barrier bag 60. The inner bag 20 can accommodate an automotive part 10. The oxygen scavenger 51 and the moisture scavenger 52 are arranged outside the inner bag 20. The high gas barrier bag 60 is formed in a bag shape such that its oxygen permeability and moisture permeability are equal to or less than predetermined values, and can enclose the inner bag 20 accommodating the automotive part 10, as well as the oxygen scavenger 51 and the moisture scavenger 52. The inner bag 20 has a specific functional portion 70 that allows passage of gas while suppressing passage of liquid.

[0021] In the present embodiment, intrusion of oxygen and moisture (water vapor) from the outside to the inside of the high gas barrier bag 60 can be suppressed. Further, oxygen and water vapor existing inside the inner bag 20 can pass to the outside of the inner bag 20 via the specific functional portion 70. The oxygen and water vapor that have passed to the outside of the inner bag 20 are removed by the oxygen scavenger 51 and the moisture scavenger 52 inside the high gas barrier bag 60. Thereby, the oxygen concentration and humidity inside the inner bag 20 are lowered, so that rusting of the automotive part 10 accommodated in the inner bag 20 can be suppressed, and oxidation of oil applied to the automotive part 10 for the purpose of rust prevention and the like can also be suppressed.

[0022] Further, in the present embodiment, since the specific functional portion 70 can suppress passage of liquid, it is possible to suppress the oil applied to the automotive part 10 from flowing out to the outside of the inner bag 20 and adhering to the oxygen scavenger 51 and the moisture scavenger 52. Thereby, performance degradation of the oxygen scavenger 51 and the moisture scavenger 52 can be suppressed. Therefore, the automotive part 10 can be stored for a long period of time while maintaining its quality.

[0023] Further, (2) in the present embodiment, the specific functional portion 70 is an opening 71 formed in the inner bag 20. An inner diameter D1 of the opening 71 is smaller than a minimum outer diameter D2 of the automotive part 10 in the longitudinal direction. The opening 71 is formed at an open end 21 of the inner bag 20 at a position other than a seal portion 22 formed by joining opposing inner surfaces of the inner bag 20.

[0024] Therefore, it is possible to prevent the automotive part 10 from coming out of the inner bag 20 through the opening 71. In addition, since the opening 71 can be formed at the same time as the sealing portion 22 is formed, the opening 71 can be easily formed.

[0025] (Second Embodiment) Figure 2 shows a package according to the second embodiment and the automotive parts contained therein. The configuration of the specific function unit 70 in the second embodiment differs from that of the first embodiment.

[0026] In this embodiment, multiple sealing portions 22 are formed at the open end 21 of the inner bag 20 in a predetermined direction x. Here, the predetermined direction x is the direction from the bottom of the inner bag 20 toward the open end 21.

[0027] More specifically, after the automotive parts 10 are placed in the inner bag 20, the inner bag 20 is formed such that, in a direction y perpendicular to a predetermined direction x, sealing portions 22 extending from one end to the other side of the open end 21 of the inner bag 20 and sealing portions 22 extending from the other end to the one end are arranged alternately in the predetermined direction x. The tip of the sealing portion 22 extending from one end of the open end 21 and the tip of the sealing portion 22 extending from the other end of the open end 21 overlap in the predetermined direction x. As a result, the opening 71 is formed in a labyrinthine shape (see Figure 2).

[0028] As described above, (3) In this embodiment, multiple sealing portions 22 are formed at the open end 21 of the inner bag 20 in a predetermined direction x. The opening 71 is formed in a labyrinthine shape. Therefore, the labyrinthine opening 71 allows for the passage of gas while more effectively suppressing the passage of liquid. Thus, the automotive part 10 can be stored for a long period of time while more effectively maintaining its quality.

[0029] (Third embodiment) Figure 3 shows a package according to the third embodiment and an automotive part contained therein. The third embodiment differs from the first embodiment in that it further includes a member for attaching to the automotive part 10.

[0030] This embodiment further includes sealing plugs 81, 82, and 83. The sealing plugs 81, 82, and 83 are formed in a bottomed cylindrical shape, for example, from resin. The sealing plug 81 is attached to the automotive part 10 so as to block the fuel supply port 11. The sealing plug 82 is attached to the automotive part 10 so as to block the injection hole 12. The sealing plug 83 is attached to the automotive part 10 so as to block the discharge port 13. The sealing plugs 81, 82, and 83 can suppress the leakage of oil from inside the automotive part 10.

[0031] In this embodiment, when storing the automotive parts 10 in the packaging 1, the automotive parts 10 with the sealing plugs 81, 82, and 83 attached are placed inside the inner bag 20.

[0032] As described above, (4) this embodiment further comprises sealing plugs 81, 82, and 83. The sealing plugs 81, 82, and 83 can suppress the leakage of oil from inside the automotive part 10. Therefore, it is possible to suppress the leakage of oil from inside the automotive part 10 into the inner bag 20, and furthermore, to suppress the leakage of oil to the outside of the inner bag 20 and adhere to the oxygen absorber 51 and the dehydrating agent 52. Thus, the quality of the automotive part 10 can be more effectively maintained while it is stored for a long period of time.

[0033] (Fourth Embodiment) Figure 4 shows a package according to the fourth embodiment and the automotive parts contained therein. The configuration of the specific function unit 70 in the fourth embodiment differs from that of the first embodiment.

[0034] In this embodiment, the functional part 70 has a hole 72 and a functional member 73. The hole 72 is formed in a circular shape, for example, to connect the inner and outer surfaces of the inner bag 20. The functional member 73 is formed in a circular sheet shape from a moisture-permeable waterproof material that suppresses the passage of liquids while allowing the passage of gases. The functional member 73 is joined to the inner bag 20 by heat sealing (heat welding), adhesive, etc., so as to close the hole 72.

[0035] In this embodiment, the seal portion 22 is formed by joining opposing inner surfaces of the inner bag 20 from one end to the other of the open end 21 after the automotive parts 10 have been placed in the inner bag 20. In other words, in this embodiment, no opening 71 is formed in the inner bag 20.

[0036] The special function section 70 (hole section 72, special function member 73) more effectively suppresses the passage of liquid while allowing the passage of gas. Therefore, oxygen and water vapor present inside the inner bag 20 can pass through the special function section 70 (hole section 72, special function member 73) to the outside of the inner bag 20. On the other hand, oil released from the automotive parts 10 inside the inner bag 20 is prevented from passing through the special function section 70 (hole section 72, special function member 73) to the outside of the inner bag 20.

[0037] As described above, in this embodiment, the quality of the automotive part 10 can be more effectively maintained while it is stored for a long period of time.

[0038] (Other embodiments) In the above-described embodiment, an example was shown in which the oxygen absorber 51 and the dehydrating agent 52 are provided together (oxygen absorber 50). In contrast, in other embodiments, the oxygen absorber 51 and the dehydrating agent 52 may be provided separately.

[0039] In other embodiments, the amount (number) and size of the oxygen absorber 51 and the dehydrating agent 52 (oxygen absorber / dehydrating agent 50) may be adjusted according to the volume of the high gas barrier bag 60 and the amount of oxygen and moisture (humidity) inside the high gas barrier bag 60.

[0040] Thus, this disclosure is not limited to the embodiments described above, and can be implemented in various forms without departing from its essence. [Explanation of symbols]
