Description

Insect-expelling food bag and processing method thereof

Technical Field

The invention relates to a food bag, in particular to an insect-expelling food bag.

Background

The food bag is a bag commonly used for packaging food, and generally comprises a paper bag, a plastic bag and an aluminum foil bag. Compared with a paper bag, the plastic bag has better water resistance and moisture resistance, and compared with an aluminum foil bag, the plastic bag has lower manufacturing cost. Plastic bags are therefore the most commonly used food bags today.

Although plastic bags have many advantages over other food bags, as the plastic bags store food for a longer period of time, the taste of the food is revealed and surrounding insects or mice are attracted. The plastic bags which are climbed and bitten by a large number of insects or rats cannot persist for a long time and can be damaged, so that the insects and the rats eat the food inside. Such plastic bags are not only not protected as they should, but also may be difficult for people to perceive that the plastic bag has been opened because only a tiny gap is pried open by insects and mice. Even cause physical discomfort after eating food moved by insects and rats.

Similarly, paper bags and aluminum foil bags cannot expel insects and cannot protect food well.

Therefore, it is urgently required to develop an insect-repellent food bag which can protect food from being contaminated by insects and mice.

Disclosure of Invention

The invention aims to provide an insect-repelling food bag to solve the problem that the existing food bag cannot repel insects.

The first scheme is as follows: the insect-repelling food bag comprises a food layer, at least three vacuum layers and a printing layer, wherein the food layer is tightly attached to food from inside to outside in sequence; a plurality of vacuum grids for loading insect-expelling mixed powder are uniformly distributed on the vacuum layer; the real blank space on each layer of vacuum layer is aligned with the vacuum grids on the other two layers; the insect-expelling mixed powder is prepared from the following raw materials in parts by weight: 4-6 parts of pepper, 4-6 parts of garlic, 5-7 parts of celery, 6-8 parts of litsea cubeba, 7-9 parts of shaddock peel and 5-7 parts of lemon.

The working principle and the beneficial effects are as follows:

the insect-repelling food bag sequentially comprises a food layer, a multi-layer vacuum layer and a printing layer from inside to outside. When the insects and the mice contact the outermost printing layer, the whole insect-repelling food bag is scratched to contact with food, the printing layer must be scratched first, then at least three vacuum layers are scratched, and the food can be contacted with the food after the food layer is scratched finally. However, when the outermost vacuum layer is scratched by an insect or a mouse, the mixed vermin-expelling powder in the empty cells is opened and emits a strong vermin-expelling smell, thereby masking the smell emitted from the food in the whole food bag. The insects and mice are repelled by the smell of the insect-repellent mixed powder and are kept away from the insect-repellent food bag after contacting the insect-repellent mixed powder.

Because the vacuum grids are filled with the insect-repelling mixed powder for repelling insects, insects and mice can be repelled by the insect-repelling mixed powder when the real space is scratched, and because the raw materials for forming the insect-repelling mixed powder are heavy-tasted materials, the taste emitted by the insect-repelling mixed powder in the scratched real space can cover the taste of food in the food bag, repel the insects and the mice around the food bag, and protect the food in the food bag from being bitten by the insects or the mice.

The insect-expelling mixed powder comprises pepper, garlic, celery, litsea cubeba, shaddock peel and lemon, the used materials are common food materials, and even if people eat the insect-expelling mixed powder by mistake, the insect-expelling mixed powder cannot cause harm to the human body. However, in the raw materials, the shaddock peel and the lemon can effectively adsorb other powder and taste besides the larger taste, and the tastes of other raw materials can be effectively combined, so that the taste of the whole insect-expelling mixed powder is uniform and lasting. In addition, the raw materials have no toxic or side effect on human bodies and are low in price. Compared with other insect repelling measures, the method is simple and easy to implement and has high safety.

At least three vacuum layers are provided, and the vacuum grids for placing the mixed insect-repellent powder are aligned. The mixed insect-expelling powder is placed in the vacuum grid, so that the mixed insect-expelling powder can be effectively protected, and the phenomenon that the mixed insect-expelling powder loses effectiveness too early after the taste is dispersed completely can be avoided. At least three vacuum layers are arranged, and the vacuum grids of each vacuum layer are aligned, so that when insects and mice break the outer food bag, even if the outer vacuum layer is broken at the same place, the inner vacuum layer can still play a role in next contact and damage, and at least three vacuum layers have at least three layers of protection. And each layer is provided with a plurality of real blank spaces which are uniformly distributed, so that the insect expelling capability and the insect expelling mixed powder at other positions cannot be influenced when different positions on the vacuum layer are scratched.

The invention can fully utilize the multilayer insect-repelling mixed powder clamped between the printing layer and the food layer to repel insects and mice, and can effectively repel insects and mice. And because the mixed insect-repelling powder is uniformly distributed in the vacuum spaces of each vacuum layer, and the vacuum layers are at least three layers which are connected in a laminated manner at one time, the insect-repelling capability of the insect-repelling food bag is omnibearing and durable, and the continuous protection effect of the insect-repelling food bag after being damaged once is facilitated.

Scheme II: further, the vacuum layer comprises two layers of transparent plastic films for wrapping the insect-repellent mixed powder.

The two layers of transparent plastic films wrap the mixed insect-repelling powder to form a vacuum layer.

The third scheme is as follows: further, the insect-expelling mixed powder comprises the following raw materials in parts by weight: pepper 4, garlic 4, celery 5, litsea cubeba 6, shaddock peel 7 and lemon 5.

And the scheme is as follows: further, the insect-expelling mixed powder comprises the following raw materials in parts by weight: 5 parts of pepper, 5 parts of garlic, 6 parts of celery, 7 parts of litsea cubeba, 8 parts of shaddock peel and 6 parts of lemon.

And a fifth scheme: further, the insect-expelling mixed powder comprises the following raw materials in parts by weight: pepper 6, garlic 6, celery 7, litsea cubeba 8, shaddock peel 9 and lemon 7.

Scheme six: the processing method of the insect-repellent food bag comprises the following steps:

the method comprises the following steps: laying a layer of transparent plastic film in a grinding tool;

step two: uniformly spraying the insect-repelling mixed powder on a transparent plastic film;

step three: spreading another layer of transparent plastic film on the insect-repelling mixed powder;

step four: compacting the two layers of transparent plastic films and the insect-repelling mixed powder between the two layers by using a sealing machine, and then separating and sealing to form a vacuum layer;

step five: sequentially overlapping tin foil paper serving as a food layer, at least three vacuum layers and a printing layer for printing, and pressing the overlapped multilayer structure into a packaging surface by using a hot press;

step six: and folding the packaging surface in half and sealing by a sealing machine to form the food bag.

Carbonic acid is a weak acid and does not react with inks that are also slightly acidic. And carbonic acid can automatically absorb heat and decompose into water and carbon dioxide when the temperature is too high, can cool down food, provides the storage environment of suitable temperature for food.

The scheme is seven: further, in the fourth step, the vacuum layer is sealed according to the uniformly distributed rectangular structure to form a plurality of real blank spaces.

The vacuum grids with the rectangular structures facilitate the longitudinal and transverse sealing of the sealing machine.

Detailed Description

The present invention will be described in further detail below by way of specific embodiments:

reference numerals in the drawings of the specification include: food layer 21, vacuum layer 23, print layer 24, vacuum grid 25.

The insect-repelling food bag comprises a food layer 21 tightly attached to food, at least three vacuum layers 23 used for filling insect-repelling mixed powder and a printing layer 24 covered outside the outermost vacuum layer 23 and used for printing product information, wherein the printing layer 24 is sequentially arranged from inside to outside; a plurality of vacuum grids 25 which are uniformly distributed and used for loading insect-expelling mixed powder are arranged on the vacuum layer 23; the vacuum grids 25 on each vacuum layer 23 are aligned with the vacuum grids 25 on the other two layers; the insect-expelling mixed powder comprises the following raw materials in parts by weight: 4-6 parts of pepper, 4-6 parts of garlic, 5-7 parts of celery, 6-8 parts of litsea cubeba, 7-9 parts of shaddock peel and 5-7 parts of lemon.

The vacuum layer 23 includes two transparent plastic films for wrapping the insect-repellent mixed powder.

The two layers of transparent plastic films wrap the insect-repelling mixed powder in the middle to form a vacuum layer 23.

The processing method of the insect-repellent food bag comprises the following steps:

step four: compacting the two layers of transparent plastic films and the insect-repelling mixed powder between the two layers by using a sealing machine, and then separating and sealing to form a vacuum layer 23;

step five: sequentially overlapping tin foil paper serving as a food layer 21, at least three vacuum layers 23 and a printing layer 24 for printing, and pressing the overlapped multilayer structure into a packaging surface by using a hot press;

Carbonic acid is a weak acid and does not react with inks that are also slightly acidic. And carbonic acid can absorb heat and decompose into water and carbon dioxide when the temperature is too high automatically, and can absorb the heat and can cool down food in the decomposition reaction process, provides the save environment of suitable temperature for food.

In step four, the vacuum layer 23 is sealed according to a uniformly distributed rectangular structure to form a plurality of real empty cells 25.

The vacuum grids 25 of rectangular structure facilitate the longitudinal and transverse directions of the sealing machine.

The insect-repellent food bag comprises a food layer 21, a multi-layer vacuum layer 23 and a printing layer 24 in sequence from inside to outside. When the insects and mice contact the outermost printing layer 24, in order to cut the whole insect-repellent food bag to contact with food, the printing layer 24 must be cut, at least three vacuum layers 23 must be cut, and the food layer 21 must be cut to contact with food. However, when the outermost vacuum layer 23 is scratched by an insect or a mouse, the vermin-expelling mixed powder in the empty cells 25 is opened and emits a strong vermin-expelling smell, covering the smell emitted from the food in the whole food bag. The insects and mice are repelled by the smell of the insect-repellent mixed powder and are kept away from the insect-repellent food bag after contacting the insect-repellent mixed powder.

Since the vacuum grids 25 contain the vermin-repellent mixed powder for vermin, it is possible to make vermin and mice repelled by the vermin-repellent mixed powder when the vacuum grids 25 are cut, and since the raw materials constituting the vermin-repellent mixed powder are materials having heavy tastes, the taste emitted from the vermin-repellent mixed powder in the cut vacuum grids 25 can mask the taste of food in the food bag, repel vermin and mice around the food bag, and protect the food in the food bag from being bitten by vermin or mice.

The insect-expelling mixed powder comprises pepper 4, garlic 4, celery 5, litsea cubeba 6, shaddock peel 7 and lemon 5, and the used materials are common food materials, so that the insect-expelling mixed powder cannot cause body harm even if people eat the insect-expelling mixed powder by mistake. However, in the raw materials, the shaddock peel and the lemon can effectively adsorb other powder and tastes except for the larger taste of the shaddock peel and the lemon, and the tastes of the other raw materials can be effectively combined, so that the taste of the whole insect-expelling mixed powder is uniform and lasting. In addition, the raw materials have no toxic or side effect on human bodies and are low in price. Compared with other insect repelling measures, the method is simple and easy to implement and has high safety.

At least three vacuum layers 23, and vacuum grids 25 for placing the mixed insect repellent powder are aligned. The mixed insect-repelling powder is placed in the vacuum grid 25, so that the mixed insect-repelling powder can be effectively protected, and the phenomenon that the mixed insect-repelling powder loses effectiveness as soon as the taste is dispersed is avoided. At least three vacuum layers 23 are arranged, and the vacuum grids 25 of each vacuum layer 23 are aligned, so that when insects and mice break the outer food bag, even if the outer vacuum layer 23 is broken at the same place, the inner vacuum layer 23 can still play a role in next contact and damage, and at least three vacuum layers 23 have at least three layers of protection. And a plurality of vacuum grids 25 are uniformly distributed in each layer, so that the insect repelling capability and the insect repelling mixed powder at other positions cannot be influenced when different positions on the vacuum layer 23 are scratched.

The invention can fully utilize the multilayer insect-repelling mixed powder clamped between the printing layer 24 and the food layer 21 to repel insects and mice, and can effectively repel insects and mice. And because the mixed insect-repelling powder is uniformly distributed in the vacuum grids 25 of each vacuum layer 23, and the vacuum layers 23 are at least three layers which are connected in a laminated manner at one time, the insect-repelling capability of the insect-repelling food bag is omnibearing and durable, and the continuous protection effect of the insect-repelling food bag after being damaged once is facilitated.

The food layer 21 and the vacuum layer 23 closest to the food layer 21 are connected to a channel sealed with wafer, which is located at the center of the food layer and covers at least ten corresponding vacuum compartments. When the food in the insect-repellent food bag is used, the glutinous rice paper is melted by adding hot water into the insect-repellent food bag, and the corresponding vacuum grids are opened. The mixed powder as seasoning is dissolved in water and soaked with food.

In the vacuum cells under these vacuum cells covered with the wafer, not the insect-repellent mixed powder but quicklime was loaded. When the glutinous rice paper is melted by water, the covered real blank spaces are opened, the top ends of the lower real blank spaces are also opened at the same time, and the quicklime in the space is exposed. Here, the vacuum compartment covered with the wafer is entirely opened, so that the vermin-repellent mixed powder therein falls into the bag formed by the two food layers to be mixed with the food. The vacuum grids filled with quicklime are opened to expose some gaps, but the quicklime in the vacuum grids is still in the vacuum grids and is not communicated with the food layer. When water is added, part of water falls into the true space filled with quicklime through the channel, the quicklime rainwater heats, and the food and the insect-expelling mixed powder wrapped in the food layer are heated. The food can be heated rapidly.

The processing method according to the present invention uses different insect-repellent mixed powders to construct the following three examples, respectively:

example 1: the insect-repellent mixed powder comprises the following raw materials in parts by weight: pepper 4, garlic 4, celery 5, litsea cubeba 6, shaddock peel 7 and lemon 5.

Example 2: the insect-repellent mixed powder comprises the following raw materials in parts by weight: 5 parts of pepper, 5 parts of garlic, 6 parts of celery, 7 parts of litsea cubeba, 8 parts of shaddock peel and 6 parts of lemon.

Example 3: the insect-repellent mixed powder comprises the following raw materials in parts by weight: pepper 6, garlic 6, celery 7, litsea cubeba 8, shaddock peel 9 and lemon 7.

The common food bags manufactured by the prior processing method are directly coated with the insect-repellent mixed powder which is the same as the insect-repellent mixed powder in the examples 1 to 3 on the surface layer thereof to be used as comparative examples 1 to 3, and the most common food bag which does not adopt the processing method of the invention and the insect-repellent mixed powder of the invention at present is used as comparative example 4. The same-sized food bags produced simultaneously in each comparative example and example were filled with the same amount of food and sealed, and the food bags in each example were placed in the same empty room. 7 starved mice were placed in the empty room each time, and after 5 minutes, the mice were repelled, and the operation was repeated to check the destruction of each bag by mice. Simultaneously, a batch of flies is put in. After comparison, the results shown in Table 1 were obtained.

TABLE 1

As can be seen from table 1, the food bags of examples 1 to 3 are the most excellent in insect-repellent and rat-repellent effects. Comparative examples 1 to 3 since the same insect-repellent mixed powder as in examples 1 to 3 was used, the initial insect-repellent and rat-repellent effects of comparative examples 1 to 3 and examples 1 to 3 were the same, but since comparative examples 1 to 3 did not adopt the processing method of the present invention, the structure of the food pouch in examples 1 to 3 was not used. Therefore, the comparative examples 1 to 3 are bitten by the mouse faster than the examples 1 to 3, and the mouse can eat the food after breaking the surface layer of the food bag coated with the vermin-repellent mixed powder.

In contrast, comparative example 4 was obtained because neither the same insect-repellent mixed powder as in the three examples nor the same processing method as in the three examples was used. Therefore, comparative example 4 has no insect-repellent effect at all. The mouse is bitten within the first minute of entering the empty room and then eats the food in the food bag.

Examples 1 to 3 do not bite at the first time because the insect-repellent food bag has a plurality of layers. The three vacuum layers 23 are all provided with the insect-repelling mixed powder layer by layer, which is equivalent to three barriers for the mouse, so that the mouse cannot bite the insect-repelling food bag under the condition that other foods can be selected. 7 starving rats, each of which eaten the food in the example pouch without being affected by the repellent effect, are treated as usual. However, since examples 1 to 3 and comparative examples 1 to 3 all had the insect repellent effect, the rats continued to eat the pouch-packed food having the good insect repellent effect after eating the pouch-packed food having no and poor insect repellent effect. As can be seen from table 1, the insect-repellent effect of example 2 was the best among the three examples.

Examining the remaining amount of food after two hours also demonstrated that examples 1 to 3 made using the scheme of the present invention had much stronger insect repellent effect than comparative examples 1 to 4.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
