Description

Porous Fruit Protection Case

The present invention relates to a fruit protection case that can protect the fruit from the outside during fruit growth of the fruit tree, and more particularly, to protect the inside from being prevented from being damaged from various pests and algae during growth before fruit harvesting. It relates to a porous fruit protective case that allows the fruit to be naturally ventilated and humidity controlled to the outside to allow normal fruit growth.

In general, fruits can be grown freshly through moderate temperatures, rainfall and sunlight, with nutrients from fertile soils. It will be stored in a cool place.

However, at the time of fruit harvesting, these fruits are not normally preserved and damaged from various pests or algae, and they may fall from the branches before they are fully ripened by the natural non-wind. Protective measures are being taken to protect.

Until now, it is a fruit protective bag using non-woven fabric that has less permeability and moderate transmittance because it has better permeability compared to general paper bags to protect fruits from various pests and improve the quality of fruits during fruit growth. Although it is used a lot, it is difficult to reliably protect from various algae, and in particular, its use is only one-time, and the inconvenience of having to purchase a new one at the next use, as well as environmental pollution due to waste of resources used once and thrown away there was.

On the other hand, fruit protection cases made of plastic materials have been introduced so that the fruit can be reliably protected from algae while being used semi-permanently, but the fruit protection cases made up of only plastic materials so far have naturally rainwater or moisture. There is a serious problem that unwanted bees or foreign substances penetrate into the plurality of drainage holes formed to be dropped and drained to prevent normal growth of the fruit.

Therefore, the present invention was developed to solve the above problems, while preventing the fruit from being damaged from various pests or algae during growth before fruit harvesting, in particular, the fruit protected inside the case body has a porous characteristic of the case body Its purpose is to provide a porous fruit protective case that can be naturally ventilated and humidity controlled by the structure and can be achieved normal fruit growth.

Porous fruit protective case of the present invention for achieving the above object is a crystalline plastic material of about 1-3mm and porous material of about 1-1.5mm so that the fruit protected inside the case body can be breathed with the outside during growth Is mixed at an addition ratio of 3.5-4.5: 1 and injection molded at a forming temperature of 180-270 ° C.

In particular, the porous material is formed of sawdust or rice hull excellent air permeability to form a large number of pores, the crystalline plastic material is made of polyethylene (PE) or polypropylene (PP) excellent in fluidity and dimensional stability during molding It features.

Hereinafter, a preferred embodiment of the porous fruit protective case according to the present invention will be described in detail based on the illustrative drawings.

1 and 2 show the inner structure and the side structure of the expanded state of the porous fruit protective case 10 according to the present invention, respectively, Figure 3 is a crystalline plastic material 12a and excellent moldability according to the present invention; An enlarged cross-sectional view of the case body 12 injection-molded with a porous material 12b which is a sawdust or rice hull having excellent porosity.

As shown in the figure, the fruit protection case 10 of the present invention, while reliably protecting the fruit 20 of the fruit tree from various pests or birds, the fruit 20 itself to fall to the floor by the load or rain-wind. Excellent extrusion molding and good acid and water resistance so that it can be structurally prevented. It can withstand the long term without being damaged in nature as well as have excellent fluidity and dimensional stability during molding so that the fruit protected inside can be breathed with the outside. Many voids are formed with the plastic material 12a, and the porous material 12b having excellent air permeability with the outside is mixed at an appropriate ratio to form a product by ordinary plastic injection molding.

In particular, the plastic material 12a is preferably a polyethylene (PE) or a polypropylene (PP), which is a thermoplastic crystalline plastic material, which is good in formability, strong in translucent, light and excellent in heat resistance, and protects the fruit. Do not put a heavy load on the tree branches.

In addition, the porous material 12b is mixed with the plastic material 12a in a relatively small addition ratio so that the fruit 20 can be respirated by being drained and vented without a separate drain hole for the plastic material 12a having excellent moldability. The porous material 12b has many voids, so that the sawdust or chaff is used so that the fruit protected inside the case body 12 can be naturally discharged while breathing with the outside, wherein sawdust or chaff alone It can be applied or mixed together.

In addition, the porous material 12b may be selectively applied to other wood by-products and agricultural product by-products having porosity, not sawdust or chaff, but a plurality of experiments have shown that the sawdust or chaff is inexpensive and molded with the plastic material 12a. It was also judged to be excellent in breathability and good, which makes it easy to solve the temperature and humidity problems at the time of fruit growth by faithfully acting as the air passage of the sawdust or chaff inside and outside the case body (12).

On the other hand, since the mixing ratio of the plastic material 12a and the porous material 12b is relatively high in moldability and durability of the product, the plastic material 12a is mixed 3.5 to 4.5 times as much as the porous material 12b. It was confirmed that the moldability and air permeability of the product when it is good, preferably the best product characteristics when mixing at an addition ratio of 4: 1.

When the plastic material 12a and the porous material 12b are mixed and injection molded through a conventional plastic injection molding machine, the molding temperature is set according to the molding temperature of the plastic material 12a, and polyethylene (PE) and The molding temperature of polypropylene (PP) is preferably about 190-270 ° C.

On the other hand, the fruit protective case 10 of the present invention is injection molded by mixing the plastic material (12a) and the porous material (12b) is a middle portion of the case body 12 on both sides is formed in the shape of a semi-circular sphere, the folding operation Body joint 16 is formed of a flexible material, which is configured so that both of the case body 12 is folded as one body to be closed in the form of a circular sphere, or spread apart to be opened in the form of a semi-circle, respectively. do. At this time, the case body 12 is fitted to each other can be modified in a variety of forms, such as an ellipsoid or other spherical body instead of a circular sphere.

In addition, both of the case bodies 11 and 12 are folded around the body joint 16 in the middle, as in the case of a conventional fruit protection case, so that they can be fitted to each other, the main end of one case body 11 While forming the fitting protrusions 12a in the longitudinal direction, the main end portion of the other case body 12 forms the fitting recesses 14b to be fitted to each other.

In addition, each of the case body 12 is formed in each of the through-holes 18 through the tap so that the fruit tap of the fruit 20 can pass through each other at the center of the upper part of the case body 12, the case body ( 12 is fixed to each of the case body 12 on the top of the tap through hole 18 so that the fixing fixture (not shown) and the tie fixing piece (not shown) are protruded so that 12) can be tied and fixed. desirable.

The porous fruit protective case 10 of the present invention formed as described above opens the case body 12 on both sides to open each other and puts the corresponding fruit 20 on one side of the case body 12 into another case body 12. When the case body 12 is slightly pressed and mutually fastened with the case body 12 on the opposite side, both case bodies 12 are coupled to each other as one body and at the top of the top center of these case bodies 12. Through the through hole 18, the fruit faucet of the fruit 20 can be passed without any difficulty.

As described above, the porous fruit protective case according to the present invention can structurally prevent the fruit from being damaged from various pests or algae during growth before fruit harvesting, and in particular, a plastic material having excellent moldability and a case body having breathability and drainage properties. Due to the material properties of the fruit inside can be naturally ventilated and humidity controlled with the outside has the effect of making a normal fruit growth.

In addition, it can be used semi-permanently instead of one-time due to the characteristics of the material, so it can reduce the waste of resources and environmental pollution caused by discarding and discarding it only once as before, and can be distinguished in the fruit protection case. It can be used more efficiently by screening and combining specific fruits or other fruits that require distinction, or even selling them by removing the stalks at the time of fruit harvesting. It is expected.
