Abstract

Provided is a paper bag for protection of a fruit. This paper bag for protection of fruit comprising an outer paper bag (1) and an inner paper bag (2) composed of oilpaper formed inside of the outer paper bag and set capable of tying an opening (3) with a coated wire (4) after covering the fruit, has a filter (5) along the inner periphery of the opening of the oil paper (2) to filter agrochemical, dust, rain water, or the like, penetrating through the opening (3). The bag is capable of preventing contact of the fruit with agrochemical and environmental pollution in a ratio >=95%, to protect the fruit such as an apple, a pear from penetration of agrochemical and damage with disease and harmful insects and enabling the growth of the fruit having quality better than conventional one.

Description

Protective paper bag for fruit

Technical field

The present invention relates to protective paper bag for fruit; particularly relate in order to protect apple and pear and other fruits to avoid the infringement of agricultural chemicals and damage by disease and insect etc.; and can cultivate than the better fruit of existing fruit quality, and can prevent agricultural chemicals and contacting fruit such as public hazards pollution more than 95%.

In general, fruit can be subjected to can causing the damage and the deformity of fruit like this, thereby causing the decline of the quality and the commodity price of commodity from too much etc. the influence of various insects, outside heat and UV sunlight in the process of growing up.

Background technology

In order to protect fruit to avoid infringement, generally be to use paper or plastic film to be made into bag, after fruit is packed into, use by the clad metal silk mouth is tightened.

But above-mentioned protection fruit is with in the paper bag, because inlet is to use by the clad metal silk to tighten, so can form little space in the porch.Therefore, the dust that suspends in the atmosphere, the rainwater when raining, and just may enter from the gap of above-mentioned inlet and contact with fruit in order to prevent and treat agricultural chemicals that the damage by disease and insect of fruit is used etc., becoming fruit growing is deformity and the low reason of quality.

Summary of the invention

The present invention is propose in order to address the above problem traditional paper bag is improved; on the inlet medial surface of protective paper bag for fruit; adhering to by cotton, synthetic fibers, cashmere human relations (Orlon; cashimilon), the filtering material that constituted such as nonwoven; with this paper bag fruit is coated; dust in the atmosphere, rainwater, agricultural chemicals etc. are when permeating by the gap of paper bag inlet; because the effect of filtering material; can be with Impurity removal; make fruit only contact pure material, thereby reach the purpose of producing fancy fruit.

Protective paper bag for fruit provided by the invention comprises outer paper bag, oilpaper, inlet; oilpaper is positioned at the inboard of outer paper bag; it is characterized in that: the medial surface at the inlet of described oilpaper is stained with filtering material, and wherein said filtering material is made of cotton, synthetic fibers, cashmere human relations and/or nonwoven.

Below in conjunction with accompanying drawing, describe in detail in order to reach the structure of the present invention of described purpose.

Protective paper bag for fruit of the present invention comprises: outer paper bag 1, oilpaper 2, inlet 3, by clad metal silk 4; There is the oilpaper 2 as interior paper the inboard of paper bag 1 outside, pack into after the fruit, inlet 3 can be with being tightened by clad metal silk 4, it is characterized in that, medial surface at the inlet 3 of described oilpaper (interior paper) 2 is stained with filtering material 5, can will filter out by enter the mouth 3 agricultural chemicals that penetrate into, dust, rainwater etc.

Fig. 4 is the profile that adheres to filtering material among the present invention along the medial surface of outer paper bag.

The wherein explanation of symbol

The outer paper bag of 1-; 2-oilpaper (interior paper); The 3-inlet; 4-is by the clad metal silk; The 5-filtering material; The 10-protective paper bag for fruit.

Embodiment

Following more specific description action effect of the present invention.

The present invention at first adopts automated system to carry out the making of protective paper bag for fruit 10 by the profile of Fig. 3 its structure as can be known.In other words, after the oilpaper 2 of the inboard of paper bag 1 formation outside as interior paper, the medial surface of paper bag 1 or oilpaper outside described (interior paper) 2 inlets 3 is stained with the filtering material 5 that is made of cotton, cashmere human relations, nonwoven, synthetic fibers etc. with binding agent.

In the protective bag of the present invention by the said method making; in order to prevent the influence to fruit in the growth stage such as damage by disease and insect, rainwater, dust, various public hazards and agricultural chemicals; with the fruit protective paper bag for fruit 10 of packing into; that is to say; after protecting paper bag that fruit is coated, the inlet 3 of described protective paper bag for fruit 10 can be with being tightened by clad metal silk 4.

At this moment, when the inside of protective paper bag for fruit 10 collection has fruit, enter the mouth 3 with being tightened on the handle of fruit, but be formed with little space at described inlet 3 places by the clad metal silk.

Like this, can protect fruit in the growth to avoid the infringement of insect, external heat and UV sunlight etc.But, infiltrate through the inside of described protective paper bag for fruit 10 for preventing space that the agricultural chemicals that damage by disease and insect sprays and the rainwater of dust in the atmosphere and pollution etc. just may form by inlet 3 places of described protective paper bag for fruit 10.Yet; in the present invention; tighten the water that space that inlet 3 places form is infiltrated by above-mentioned; before the fruit of the inside that touches protective paper bag for fruit 10; because in the filtration of the filtering material 5 that inner peripheral surface adhered to is made of cotton, cashmere human relations, nonwoven, synthetic fibers etc. of inlet 3 and can be with Impurity removal, what therefore contact with fruit surface be pure material only just.

Like this, can prevent trouble before it happens because of various insects, infringement that dust and exposed to pesticides caused, therefore just can not access and damage the fruit in vegetative period, and colory fruit.

By above explanation as can be known; the present invention is in order to prevent trouble before it happens because of contacting various insects, dust, public hazards and infringement that rainwater, agricultural chemicals caused to the fruit in vegetative period; be stained with filtering material in inboard along the porch of protective paper bag for fruit; make the surface of fruit only contact pure material, thereby reach the purpose that obtains colory fruit.

Claims

1, a kind of protective paper bag for fruit; comprise: outer paper bag (1), oilpaper (2), inlet (3); oilpaper (2) is positioned at the inboard of outer paper bag (1); it is characterized in that: the medial surface at the inlet (3) of described oilpaper (2) is stained with filtering material (5), and wherein said filtering material (5) is made of cotton, synthetic fibers, cashmere human relations and/or nonwoven.
