Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a packaging bag for steaming and boiling. Background Art

[0002] Steamed food is loved by the general public for its unique cooking method and taste. Some steamed foods are stored in packaging bags. Steamed packaging bags are generally composite plastic film bags that can be heated. They have the advantages of both canned containers and boiling water-resistant plastic bags. Therefore, this type of steamed packaging bag is also called "soft canned food".

[0003] However, after steaming or cooking food, the food often releases a large amount of water or soup, and some brine foods themselves will add juice into the packaging bag. These liquids accumulate inside the packaging bag. After the user tears open the sealing strip of the packaging bag, it is easy to cause liquid leakage, which may dirty the user's hands or clothes. Subsequent disposal may also easily contaminate the trash can, causing inconvenience to the user. In addition, if the food is not eaten in time, it will be soaked in the liquid in the packaging bag for a long time, which will also affect the quality and taste of the food. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a packaging bag for cooking to solve the above problems.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the utility model shown in the accompanying drawings and described according to the accompanying drawings are merely exemplary, and the utility model is not limited to these embodiments.

[0026] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not very relevant are omitted.

[0027] Reference Figure 1 As shown, an embodiment of the utility model provides a packaging bag for cooking, the packaging bag for cooking comprises a packaging bag body 1 and an easy-tear seal 2, the packaging bag body 1 comprises a containing cavity 11, a side liquid absorption cavity 12 and a bottom liquid absorption cavity 13.

[0028] The top of the accommodating cavity 11 is open and sealed by the tear-off seal 2. The side liquid absorption cavity 12 is located at one side of the accommodating cavity 11, and the bottom liquid absorption cavity 13 is located below the accommodating cavity 11. Figure 2 As shown, the surfaces of the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 are provided with a plurality of liquid permeable holes 10, and the surfaces of the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 are covered with a barrier film layer 14 for covering the liquid permeable holes 10, and the end of the barrier film layer 14 is bonded to the lower side of the easy-tear seal 2. Figure 3 As shown, the barrier film layer 14 can be torn off along with the tearable seal 2 to expose the blocked liquid permeable hole 10, the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 are filled with gas, and the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 are both provided with liquid absorption sponge blocks 15.

[0029] The cooking packaging bag is provided with a side liquid absorption cavity 12 on one side of the accommodating cavity 11 and a bottom liquid absorption cavity 13 at the bottom of the accommodating cavity 11, so that a large amount of water or soup or other liquid released by the food in the accommodating cavity 11 can flow into the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13, and be absorbed by the liquid absorption sponge block 15 located inside the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13, so as to quickly lower the liquid level line in the accommodating cavity 11 and avoid soiling the user's hands or clothes. As the time after the packaging bag is opened increases, most of the subsequent liquid will be concentrated in the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 to prevent the food from being immersed in the liquid in the accommodating cavity 11 for a long time, thereby reducing the impact on the quality and taste of the food, and also reducing the pollution of the trash can after the cooking packaging bag is discarded, thereby improving the user experience.

[0030] Specifically, after the user tears off the easy-tear seal 2, the barrier film layer 14 can be torn off along with the easy-tear seal 2, exposing the liquid-permeable holes 10, that is, through holes, blocked by the barrier film layer 14, so that the liquid in the accommodating cavity 11 can enter the side liquid-absorbing cavity 12 and the bottom liquid-absorbing cavity 13 through each liquid-permeable hole 10, and then be absorbed by the liquid-absorbing sponge block 15 located inside the side liquid-absorbing cavity 12 and the bottom liquid-absorbing cavity 13. Moreover, after the barrier film layer 14 is torn off and the liquid-permeable holes 10 are exposed, the gas filled in the side liquid-absorbing cavity 12 and the bottom liquid-absorbing cavity 13 is released, and the volume of the side liquid-absorbing cavity 12 and the bottom liquid-absorbing cavity 13 shrinks, which will promote and accelerate the absorption of the liquid in the accommodating cavity 11. Before the cooking packaging bag is opened, the gas-filled side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 can play a protective and buffering role for the cooking packaging bag, thereby reducing the possibility of damage to the cooking packaging bag during transportation and the like.

[0031] Furthermore, the bottom of the side liquid absorption cavity 12 is interconnected with the bottom liquid absorption cavity 13. The interconnection between the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 is conducive to the balanced exchange of liquid, expands the liquid storage area, and improves the liquid absorption efficiency.

[0032] Exemplarily, nitrogen is filled in the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13. Nitrogen has stable chemical properties and can be used as a protective gas to prevent corrosion and extrusion. It has low cost and is a commonly used protective gas in food packaging.

[0033] After the easy-tear seal 2 is torn, it is convenient for the user to easily take out the barrier film layer 14. The ends of the barrier film layer 14 are stacked and concentrated at the front end of the easy-tear seal 2. The barrier film layer 14 can be separated from the easy-tear seal, so that the user can directly grab the end of the barrier film layer 14, which is more convenient to operate.

[0034] Some water-absorbing materials that meet food safety requirements can be used as liquid-absorbing materials to fill the cavity. In this embodiment, the side liquid-absorbing cavity 12 and the bottom liquid-absorbing cavity 13 are also provided with water-absorbing resin blocks and non-woven fabric balls.

[0035] The plurality of liquid permeable holes 10 are distributed in an array on the surface of the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 . The liquid permeable holes 10 are arranged regularly, and the flow rate of the liquid in the accommodating cavity 11 through the liquid permeable holes 10 is higher.

[0036] Taking into account the food safety and cooking requirements, the materials of the containing cavity 11, the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 need to meet the requirements of freshness preservation, high temperature resistance and barrier performance. In this embodiment, the containing cavity 11, the side liquid absorption cavity 12 and the bottom liquid absorption cavity 13 are all composite film cavities including a PET film layer, an aluminum foil layer, a PA film layer and a PE film layer. The PET material is polyethylene terephthalate, which has excellent creep resistance, fatigue resistance and friction resistance, and is not easy to deform; the PA material is polyamide, which has good physical strength and puncture resistance, and the PE material is polyethylene, which is a commonly used material for fresh-keeping packaging bags. The composite film cavity thus formed can meet the above requirements.

[0037] Furthermore, the barrier film layer 14 is a PVA material layer, that is, a polyvinyl alcohol material layer, which has excellent water-barrier performance.

[0038] A buffer chamber 16 filled with nitrogen is connected to the side of the accommodating chamber 11 opposite to the side liquid absorption chamber 12 to more comprehensively protect the cooking packaging bag, and cooperates with the side liquid absorption chamber 12 and the bottom liquid absorption chamber 13 to play a buffering role, thereby reducing the possibility of damage to the cooking packaging bag during transportation.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0040] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
