AI Technical Summary
When the traditional braised egg food packaging bag is opened, the juice is easy to splash, affecting the consumer experience.
A splash-proof juice packaging bag composed of a first packaging film and a second packaging film is used. The second packaging film bulges outward to form an inner cavity, which is connected by heat sealing. An opening is left on the side of the sealed part. The diameter of the shrinkage opening is smaller than the maximum diameter of the inner cavity to form a gap cavity. After vacuuming, the marinade is distributed in the inner cavity and on the marinated eggs. When unsealing, it is difficult for the marinade to enter the gap cavity, kinetic energy is consumed, and the buffering effect is significant.
Effectively prevent the marinade from spraying out from the opening, improving the consumer experience.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of food packaging, in particular to a splash-proof packaging bag for braised egg food. Background Art
[0002] Braised egg food is generally packaged in food-grade stretch film vacuum packaging bags. Since it contains a certain amount of marinade or juice such as chili oil and chili water, the problems with traditional stretch film packaging bags are: the heat seal layer is too thick, which requires a lot of force to open the seal, and when consumers uncover or tear the bag, the juice will splash out instantly due to the pressure, easily staining clothes or the ground, and is often difficult to clean, which is very troublesome and greatly affects the consumer experience. The reason for the above problems is that after the vacuum packaging is completed, the plastic film of the bag forms a vacuum and taut wrap with the food, causing the plastic film to be stretched and in a taut state. When the consumer opens the bag, the plastic film of the bag shrinks, thereby squeezing the food and juice in the bag, squeezing the juice out of the gap and splashing. Utility Model Content
[0003] In view of the above problems, the utility model provides a sauce-proof juice-splashing packaging bag for braised egg food, which is used to solve the problem of juice splashing when the existing sauce-proof egg food packaging bag is opened, and has a good sauce-proof juice-splashing effect.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A splash-proof packaging bag for braised egg food comprises a first packaging film and a second packaging film, wherein the first packaging film is planar, and the second packaging film bulges outward to form an inner cavity for accommodating the braised egg; the first packaging film and the second packaging film are interconnected by heat sealing to form a sealing portion for sealing the inner cavity, and an unsealable opening is left on the side of the sealing portion; a circle of inwardly concave arc surface is formed at the connection between the second packaging film and the first packaging film, and this circle of arc surface constitutes a shrinkage opening, and a gap cavity is formed between the shrinkage opening and the first packaging film; the diameter of the shrinkage opening is smaller than the maximum diameter of the inner cavity.
[0006] As a further improvement of the above solution, the inner cavity bulges outward to form a spherical or ellipsoidal shape.
[0007] As a further improvement of the above solution, the first packaging film has a harderness than the second packaging film.
[0008] Compared with the prior art, the beneficial effects of the present invention are:
[0009] The marinated egg is placed in the inner cavity, and the shrinkage port is used to shrink the marinated egg in the inner cavity by vacuuming, and the marinade is distributed on the marinated egg as much as possible; a vacuum cavity is formed in the gap cavity; when the seal is opened, it is more difficult for the marinade to be discharged from the inner cavity into the gap cavity, and more kinetic energy is consumed. At the same time, the gap cavity plays a good buffering role, so that the marinade cannot rush out from the unseal port, thereby achieving an anti-splashing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with the embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.
[0014] like Figure 1-2 As shown, the specific scheme of this embodiment is: a splash-proof packaging bag for braised egg food, comprising a first packaging film 1 and a second packaging film 2, the first packaging film 1 is flat, and the second packaging film 2 bulges outward to form an inner cavity 7 for accommodating the braised eggs; the first packaging film 1 and the second packaging film 2 are interconnected by heat sealing to form a sealing portion 5 for sealing the inner cavity 7, and an unsealing opening 6 is left on the side of the sealing portion 5; a circle of inwardly concave arc surface is formed at the connection between the second packaging film 2 and the first packaging film 1, and this circle of arc surface constitutes a shrinkage opening 3, and a gap cavity 4 is formed between the shrinkage opening 3 and the first packaging film 1; the diameter of the shrinkage opening 3 is smaller than the maximum diameter of the inner cavity 7.
[0015] As a preferred embodiment of the above embodiment, the inner cavity 7 bulges outward to form a spherical or ellipsoidal shape.
[0016] As a preferred embodiment of the above embodiment, the hardness of the first packaging film 1 is greater than that of the second packaging film 2 .
[0017] The specific working principle of this utility model:
[0018] This packaging bag is an improvement to the problem that when a traditional vacuum food packaging bag is opened, the juice in the packaging bag is easily splashed out due to the pressure. The packaging bag is formed by heat sealing a first packaging film 1 and a second packaging film 2, wherein the first packaging film 1 is generally flat, while the second packaging film 2 is convex outward in a spherical or ellipsoidal shape, and the convex part forms an inner cavity 7; the braised egg and the juice are located in the inner cavity 7; the packaging bag is characterized by the presence of a contraction port 3 and a gap cavity 4; Figure 2 As shown, the diameter a of the contraction port 3 is smaller than the maximum diameter b of the inner cavity 7. When sealing the bag, vacuum is required. The contraction port 3 fixes the marinated egg in the inner cavity 7 and distributes most of the marinade in the inner cavity 7 and on the marinated egg. The gap cavity 4 is in a vacuum state. When the unseal 6 is opened, it is more difficult for the marinade to be discharged from the inner cavity 7 to the gap cavity 4, and more kinetic energy is consumed. At the same time, the gap cavity 4 plays a better buffering role, so that the marinade cannot rush out from the unseal 6, thereby achieving an anti-splashing effect.
