Abstract
Description
Technical Field
[0001] This application relates to the field of adsorbent product technology, and more particularly to a packaging container and packaging product. Background Technology
[0002] To extend the shelf life of plants such as flowers and vegetables, or fresh foods, they are usually placed in refrigerated environments such as cold storage. However, this preservation method is not conducive to the purchase of these products, and the previous preservation measures are immediately lifted after the plants or foods are sold to the buyers. Summary of the Invention
[0003] In order to solve at least one of the above-mentioned technical problems, this application proposes a packaging container with a preservation function and a packaging product configured with such a packaging container.
[0004] Firstly, a packaging container is proposed, comprising:
[0005] An inner container, which defines a first containment space within itself for containing the packaged item;
[0006] An outer container that houses the inner container and defines a second accommodating space outside the inner container within it, wherein the inner container has higher air permeability than the outer container;
[0007] The preservative is contained in the second containment space.
[0008] In some possible implementations, at least a portion of the inner container is formed of breathable packaging paper.
[0009] In some possible implementations, the thickness of the packaging paper is 0.6-0.8 mm.
[0010] In some possible implementations, the outer container is a transparent plastic bag, and at least a portion of the inner container is formed as a transparent structure suitable for observing the packaged item.
[0011] In some possible implementations, the inner container has:
[0012] The opening is defined by the packaging paper;
[0013] A transparent film is used to seal the opening, forming the transparent structure.
[0014] In some possible implementations, the plastic bag is a PE plastic bag, and the packaging paper contains PE fibers.
[0015] In some possible implementations, the inner container is a box or a bag.
[0016] In some possible implementations, the preservative is a humectant, desiccant, oxygen absorber, or ethylene remover.
[0017] Secondly, a packaged product is proposed, including:
[0018] The packaging container as described in the first aspect, and
[0019] The packaged item.
[0020] In some possible implementations, the packaged item is a plant or food.
[0021] The packaging container provided according to this application includes: an inner container defining a first containment space therein for containing the packaged item; an outer container containing the inner container and defining a second containment space therein located outside the inner container, wherein the inner container has higher permeability than the outer container; and a preservative contained in the second containment space. With this design, based on the higher permeability of the inner container, the preservative disposed in the second containment space can effectively provide preservation support for the packaged item in the first containment space, and based on the lower permeability of the outer container, the influence of the external environment on the lifespan of the preservative is suppressed.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.
[0037] In the description of this application, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects, and, for example, the term "first element" itself does not imply the existence of a "second element," nor does the term "second element" itself imply the existence of a "first element." Furthermore, words such as "a" or "one" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates not less than two.
[0038] In the description of this application, the terms "comprising" or "having" indicate the presence of the said features, numbers, operations, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, numbers, operations, elements, and / or combinations thereof.
[0039] In the description of this application, references to "one embodiment" or "some embodiments" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.
[0040] Figure 1 The illustration schematically shows a packaging product 100 provided in an embodiment of this application. The packaging product 100 includes a packaging container 10 and a packaged item 20 packaged in the packaging container 10. The packaged item 20 may be food or plants such as flowers or vegetables, and the packaging container 10 can provide a preservation environment for the packaged item 20 to extend its shelf life.
[0041] The packaging container 10 includes an inner container 1, an outer container 2 that contains the inner container 1, and a preservative 3 located between the outer container 2 and the inner container 1. Figure 2 This diagram shows the packaged product 100 after the outer container 2 has been removed.
[0042] More specifically, the inner container 1 is formed as a box with a cuboid shape, thereby defining a first cuboid-shaped receiving space 4 inside, in which the packaged item 20 is housed. Furthermore, the majority of the inner container 1 is formed of wrapping paper 8 with excellent breathability, and has a square opening 6 defined by the wrapping paper 8. This opening 6 is sealed by a transparent film 7 attached to the periphery of the wrapping paper 8, so that the packaged item 20 can be observed from the outside through the transparent film 7 even without opening the inner container 1. With this design, when the packaged item 20 is flowers, the buyer can easily select a satisfactory product from the many packaged products 100.
[0043] In practice, the inner container 1 can be manufactured by die-cutting the packaging paper 8. Furthermore, this packaging paper 8, with its excellent air permeability, is commercially available; its air permeability is several times that of ordinary white cardboard.
[0044] An outer container 2 contains an inner container 1 and defines a second containing space 5 located outside the inner container 1 within the outer container 2. The second containing space 5 is formed between the outer container 2 and the inner container 1 and can be defined by the outer surface of the inner container 1 and the inner surface of the outer container 2. In this embodiment, the outer container 2 is a transparent PE plastic bag, so the air permeability of the inner container 1 is much higher than that of the outer container 2. Therefore, water vapor and oxygen can easily flow between the second containing space 5 and the first containing space 4, but it is difficult for them to flow between the second containing space 5 and the external environment.
[0045] In addition, since the outer container 2 is a transparent PE plastic bag and a part of the inner container 1 is formed into a transparent structure, the packaged item 20 inside can be observed from the outside of the outer container 2 without opening the outer container 2.
[0046] The preservative 3 is contained in the second containment space 5. Since the inner container 1 has higher air permeability than the outer container 2, the preservative 3 placed in the second containment space 5 can effectively provide preservation support for the packaged item 20 in the first containment space 4 and suppress the impact of the external environment on the service life of the preservative 3.
[0047] The preservative 3 can be a humectant, desiccant, oxygen absorber, or ethylene remover. In one embodiment, the packaged item 20 is a moisture-loving flower, the preservative 3 is a humectant, and the humectant is sealed in a highly moisture-permeable small packaging bag and placed in the second containing space 5.
[0048] In some embodiments, the transparent film 7 of the inner container 1 is a PE plastic film, which is consistent with the material (PE) of the outer container 2, thus facilitating the recycling and reprocessing of the materials in the packaging container 10.
[0049] Despite Figure 1 In the diagram, the inner container 1 is shown as a box with a rigid shape, and the outer container 2 is shown as a flexible plastic bag. However, it should be understood that the inner container 1 can also be formed as a plastic bag with high air permeability, and the outer container 2 can be formed as a box with low air permeability.
