TECHNICAL FIELD
[0001] The utility model belongs to the technical field of preservative bag, specifically relates to a preservative bag convenient to use. BACKGROUND
[0002] Preservative bag mainly refers to the bag for preserving vegetables, fruits, cereals, cooked food and other food made of food preservative film, and is widely used in daily life, its principle is to form a relatively closed space in the bag to reduce the contact between the outside and the inside environment, thereby prolonging the preservation period of food, and the preservative bag is usually made of high-density polyethylene or polyvinyl chloride plastic material, which has good oxygen, water vapor and aroma barrier properties, and can effectively slow down the oxidation speed of food, water evaporation and the invasion of external odor.
[0003] At present, the preservative bags on the market mostly adopt a completely sealed mode to store food in the bag body, but some fruits or vegetables and other food will undergo respiration during storage, produce carbon dioxide and consume oxygen, although the sealed packaging can isolate the invasion of external microorganisms, but it can also lead to imbalance of the gas environment in the packaging and accelerate the aging process of food.
[0004] Therefore, the utility model provides a preservative bag convenient to use to solve the above problems. UTILITY MODEL CONTENTS
[0005] In order to achieve the above purpose, the utility model provides the following technical scheme: a preservative bag convenient to use, comprising a bag body with an opening, a cover connecting portion connected with the bag body is arranged on one side of the opening end of the opening, a concave cavity is formed between the cover connecting portion and the bag body, when the opening of the bag body is turned over into the concave cavity, the cover connecting portion covers the opening to form a relatively sealed space in the bag body.
[0006] As a preferred preservative bag convenient to use of the utility model, a through hole two is arranged in the bottom of the bag body opposite to the opening.
[0007] As a preferred preservative bag convenient to use of the utility model, the top end of the cover connecting portion is integrally connected with one side of the opening end of the opening, and the two sides are hot-pressing connected with the bag body to form a concave cavity between the bottom of the cover connecting portion and the bag body.
[0008] As a preferred preservative bag convenient to use of the utility model, a hanging portion is connected with the side opposite to the cover connecting portion of the opening end of the opening through a punching line.
[0009] As a preferred preservative bag convenient to use of the utility model, a through hole one is arranged on the surface of the hanging portion opposite to the cover connecting portion.
[0010] The utility model discloses a convenient to use's fresh -keeping bag optimizes, the opening inboard and the bag body inside still are equipped with opposite sealing pressure strip, when the sealing pressure strip of opening inboard and the bag body is sealed, to make the bag body form sealed.
[0011] Compared with the prior art, the utility model has the advantages of:
[0012] 1. The utility model discloses a cover joint part is set up to the opening side of the bag body, when the food is filled in the bag body, the opening is turned over, and the cover joint part covers the opening, to form the relatively closed space in the bag body, which can slow down the outside air entering, and the gas environment imbalance caused by the food breathing in the bag can not be produced, the food preservation is guaranteed, and the production cost is effectively reduced.
[0013] 2. Secondly, the utility model discloses a sealing pressure strip is set up to the opening inboard and the bag body inside, when the two sealing pressure strips are pressed, the bag body can form the sealed space, so that the bag body can form the relatively sealed or completely sealed according to the actual use demand, and the practicality is effectively improved.

[0022] Clearly and completely describe the technical scheme in the embodiments of the utility model with the drawings in the embodiments of the utility model below, obviously, the described embodiments are only a part of the embodiments of the utility model, and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the scope of the utility model protection.
[0023] The utility model relates to a kind of fresh-keeping bags of convenient use, as shown in Figure 5 It includes the fresh-keeping bag body 1 formed by the plastic film along fold line 7 staggered folding and along heat-pressing line 8 press-connection, as shown in Figures 1-2 .
[0024] The bag body 1 has an opening 2, and cover joint part 3 is formed on the side of opening 2 after staggered folding and heat pressing, and the recess cavity for accommodating opening 2 is formed between cover joint part 3 and bag body 1;As shown in Figure 4 When using, by turning over opening 2, opening 2 is placed in the recess cavity formed between cover joint part 3 and bag body 1, to realize the covering of opening 2 by cover joint part 3, and the food in the bag will also press cover joint part 3 and opening 2 side wall together, so that the relatively sealed state is formed in bag body 1, to slow down the entry of external air, since the internal and external environment is not completely sealed, therefore, the balance of gas environment in the bag can be maintained, to realize the effective preservation of food.
[0025] Further, as shown in Figure 3 The opening end of opening 2 is connected with hanging part 9 on the side opposite to cover joint part 3 through punching line 4, and opposite through hole one 5 for hanging is also provided on hanging part 9;When using, by hooking the hook on wall with through hole one 5, bag body 1 can be hung, at the same time, if pulling bag body 1, bag body 1 will be separated from hanging part 9 under the action of punching line 4, to facilitate taking down bag body 1 for use.
[0026] Further, in order to reduce the influence of humidity generated by temperature difference effect in bag body 1, opposite through hole two 6 for ventilation and drainage can be provided on the bottom of bag body 1, which can well discharge the humidity and moisture in bag body 1, to prevent the food preserved in bag body 1 from being damp and deteriorated.
[0027] Further, as shown in Figure 6As shown, the sealing pressing strips 10 are arranged in the inside of the bag body 1 and above the through hole two 6 and the inside of the opening 2, and the sealing pressing strips 10 have mutually matched rubber concave-convex sealing strips, which can be connected together to form a seal when the concave-convex sealing strips are pressed against each other, and the principle of the sealing pressing strips 10 is the same as that of the self-sealing bag in the prior art, and thus will not be described in detail here; when it is needed to store food such as dried fruits which needs to be sealed, the bag body 1 can be completely sealed by the sealing pressing strips 10, so as to facilitate the storage of the food such as dried fruits.
[0028] In conclusion, the bag body 1 can selectively store the food in a relatively sealed or completely sealed manner according to the different types of food to be stored, so as to improve the practicability and facilitate the use.
[0029] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features.
