Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of apple packaging protection, in particular to an external protection device for space-ready-to-eat fresh apples. Background Technique
[0002] With the rapid development of the aerospace industry, the demand for aerospace food is increasing day by day. In the aerospace environment, due to special conditions such as high stress and microgravity, traditional fruit protection devices can no longer meet the protection requirements for fruits. Especially for high-value fruits such as ready-to-eat fresh apples, the design of their external protection devices is particularly important.
[0003] When facing the aerospace high-stress environment, traditional apple protection devices often fail to provide sufficient protection, resulting in apples being easily damaged by external forces such as extrusion and collision during transportation and storage. Secondly, traditional protection devices often lack the supporting effect on apples. In the aerospace microgravity environment, apples are prone to floating and moving, causing mutual collision and damage. Moreover, in the aerospace environment, the respiratory metabolism of apples will produce a certain amount of carbon dioxide and other gases. If the air permeability of the protection device is poor, these gases cannot be discharged in time, which will lead to an increase in the internal temperature and humidity of the fruits, thus accelerating the spoilage and deterioration of apples. Content of the Utility Model
[0004] In order to overcome the shortcomings existing in the above background technique, the purpose of the utility model is to provide an external protection device for space-ready-to-eat fresh apples, which not only plays a role in product protection but also can conduct ventilation and air permeability to ensure that the products of respiratory metabolism can be diluted by the outside air and will not cause damage to the fruits.
[0005] The technical solution is: an external protection device for space-ready-to-eat fresh apples, including a hollow corrugated box with an open top, a cover plate is provided on the top of the hollow corrugated box, a middle lining is provided inside, cushion plates are respectively arranged on the upper and lower sides of the middle lining, several fruit placement holes are arranged at intervals and penetrate through the upper and lower surfaces of the middle lining, vertical holes corresponding to the positions of the fruit placement holes are provided on the cushion plates, and several ventilation holes are uniformly arranged on the cover plate, the side surfaces and the bottom surface of the hollow corrugated box.
[0006] Further, the hollow corrugated box is made of 3 mm thick polypropylene corrugated board.
[0007] Further, the aperture of the ventilation hole is not less than 20 mm.
[0008] Further, the cushion plates and the middle lining are made of polyethylene foam.
[0009] Further, the aperture of the vertical hole is not less than 30 mm.
[0010] Further, the aperture of the fruit placement hole is 75 - 78 mm, and the height is 65 - 70 mm.
[0011] Further, a plurality of strip-shaped ribs are formed along the circumferential direction of the inner wall of the fruit placement hole. The strip-shaped ribs are in the same direction as the fruit placement hole. After the ribs are provided, when an apple is placed in the fruit placement hole, there are gaps between the ribs, which improves the air circulation. In addition, the protruding ribs have a better supporting effect on the apple and are more firm.
[0012] Further, a plurality of vertical concave portions are formed on the outer side wall of the middle liner. The concave portions are arranged between two adjacent fruit placement holes. Setting the concave portions can, on the one hand, improve the supporting strength, on the other hand, reduce the overall weight, and is also conducive to air circulation.
[0013] The beneficial effects are as follows:
[0014] By using a hollow corrugated box as the outer packaging, its structure is firm and has strong impact resistance. It can effectively resist external impacts and squeezes, and protect the apples from damage.
[0015] A middle liner and a cushion plate are arranged in the hollow corrugated box to form a multi-layer buffer structure. These buffer materials have good elasticity and energy absorption performance, and can effectively reduce the damage to the apples caused by external impacts.
[0016] Ventilation holes are opened on the hollow corrugated box and the cushion plate to ensure that the respiratory metabolites generated by the apples during storage and transportation can be discharged in time, and the internal environment of the fruits is kept stable.
[0017] By setting a support structure on the middle liner and the cushion plate, the apples can be effectively fixed and supported, preventing the apples from floating and moving and colliding with each other and being damaged in the micro-gravity environment of spaceflight.
[0018] In summary, the external protection device for fresh apples for instant consumption in space provided by the present utility model has the advantages of high protection level, good buffering performance, excellent air permeability, and strong support, ensuring to meet the random vibration, external force resistance, sine, and anti-sine impact resistance caused during the ascent of the spacecraft. The materials used can meet the environmental requirements of the space capsule, and have high practical value and market prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their detailed description will be omitted.
[0024] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the icon to another component, these terms are used in this specification only for convenience, for example, according to the directions of the examples described in the accompanying drawings. It can be understood that if the device of the icon is turned upside down, the component described as "upper" will become the component "lower". Other relative terms such as "high", "low", "top", "bottom", "left", "right", etc. also have similar meanings. When a structure is "on" another structure, it may mean that a structure is integrally formed on another structure, or that a structure is "directly" provided on another structure, or that a structure is "indirectly" provided on another structure through another structure.
[0025] Figure 1 The schematic three-dimensional structure diagram of the external protection device for instant fresh apples in space shown includes a hollow corrugated box 1 with an open top. A cover plate 2 is provided at the top of the hollow corrugated box 1. The cover plate 2 can be covered on the hollow corrugated box 1 or can adopt an integrally formed flip structure. The hollow corrugated box 1 and the cover plate 2 are made of 3-mm thick polypropylene corrugated board. The hollow corrugated box 1 made of polypropylene corrugated board has excellent cushioning performance and can effectively protect the apples from being squeezed, vibrated, etc. during transportation. In addition, several ventilation holes 5 with a pore diameter of not less than 20 mm are provided on the four sides and one bottom surface of the hollow corrugated box 1. By designing the ventilation holes 5, this helps air circulation, reduces the temperature of the apples, prevents the apples from generating heat during the oxidation process, and further extends the freshness preservation period of the apples.
[0026] As Figure 2 and Figure 3As shown, a horizontally arranged middle liner 4 and a cushion plate 3 are provided inside the hollow corrugated box 1. A cushion plate 3 is provided on each of the upper and lower sides of the middle liner 4. The number of middle liners 4 is determined according to the height of the hollow corrugated box 1. Through comprehensive comparison of air permeability, the extrusion force between each other, and the loading capacity, setting two layers of middle liners 4 is the best choice. The middle liner 4 is provided with several fruit placement holes 7 arranged at intervals and penetrating through its upper and lower surfaces. The aperture of the fruit placement hole 7 is about 75 - 78 mm, preferably 78 mm; the height of the placement hole 7 is about 65 - 70 mm, preferably 70 mm. The inner wall of the fruit placement hole 7 is formed with a plurality of strip-shaped ribs 8 along its circumferential direction, and the strip-shaped ribs 8 are in the same direction as the fruit placement hole 7. After setting the ribs, when apples are placed in the fruit placement holes 7, the gaps between the ribs can improve the air circulation. In addition, the protruding ribs have a better supporting effect on the apples. It should be noted that a plurality of vertical concave portions 9 are formed on the outer side wall of the middle liner 4, and the concave portions 9 are arranged between two adjacent fruit placement holes 7. By setting the concave portions 9, on the one hand, the supporting strength of the middle liner 4 can be improved, and on the other hand, the weight of the overall hollow corrugated box 1 can be reduced.
[0027] The cushion plate 3 is provided with vertical holes 6 corresponding to the positions of the fruit placement holes 7, and the aperture of the vertical holes 6 is not less than 30 mm. Among them, the cushion plate 3 and the middle liner 4 are made of polyethylene foam. The cushion plate 3 and the middle liner 4 are made of polyethylene foam material, which can effectively reduce the damage caused by external impact to the apples and ensure the safety of the apples during transportation. And the porous structure inside the polyethylene foam helps to maintain the humidity inside the package and slow down the evaporation of the moisture of the apples. This moisture retention function can extend the freshness period of the apples and keep their freshness and taste.
[0028] The above embodiments only represent the preferred implementation modes of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
