Description

Technical Field

[0001] This application relates to a bag, and more particularly to a ventable high-temperature sterilization bag. Background Technology

[0002] Traditional sealed food packaging materials are mainly made of plastic film into sealed bags. During the heating process, especially when microwaved, the vapor in the sealed space of the bag heats up rapidly. The sealing rate and strength of the packaging material are often insufficient and cannot withstand the internal pressure, which makes the sealed bag prone to gas explosion.

[0003] Therefore, in the current design, a small opening must be torn in the plastic film to prevent the food and air inside the bag from expanding excessively when microwaved.

[0004] However, leakage of juices inside is still unavoidable during the heating process, so there is still room for improvement in conventional sealed bags. Utility Model Content

[0005] The main purpose of this application is to solve the problem that when microwave heating, it is necessary to tear a hole in the sealed bag beforehand and liquid may easily leak out during the heating process.

[0006] To achieve the above objectives, one embodiment of this application provides a ventable high-temperature sterilization bag, comprising a body. The body is made of a high-temperature resistant material and has an accommodating space. One end of the body has a filling port for filling articles, and the side of the body has at least one U-shaped venting section, with at least 3 / 5 of the volume of the venting section located in the accommodating space.

[0007] Another embodiment of this application provides a high-temperature sterilization bag with exhaust capability. It is a body, which consists of a first heat-resistant layer and a second heat-resistant layer that are stacked and sealed together, forming a sealing strip on each of the two sides. One of the sealing strips has a through hole. The body has an accommodating space, a filling port and an exhaust part. The accommodating space and the through hole are not connected. The filling port is located at one end of the body and the exhaust part is located on the side surface of the body.

[0008] With the above structure, the advantage of this application is that it provides a high-temperature sterilization bag that can effectively vent gas during microwave heating. When heated, the high-temperature sterilization bag does not need to be torn open, and steam can be smoothly discharged through the vent, thereby avoiding the problem of excessive internal pressure leading to gas explosion.

[0016] To facilitate the explanation of the central idea expressed in the above-described novel content section of this application, specific embodiments are provided below. The various objects in the embodiments are depicted to a scale, size, deformation, or displacement suitable for illustration, rather than being drawn to scale.

[0017] Please refer to Figures 1 to 4 This application discloses a high-temperature sterilization bag with exhaust capability, comprising a body 10. The body 10 is formed by overlapping and sealing a first heat-resistant layer 101 and a second heat-resistant layer 102. Figure 4 The second heat-resistant layer 102 is indicated by a dashed line on the other side. The body 10 is made of a high-temperature resistant material and has a accommodating space 11. One end of the body 10 has a filling port 12 for filling with items. The side of the body 10 has at least one U-shaped exhaust section 13. At least 3 / 5 of the volume of the exhaust section 13 is located in the accommodating space 11.

[0018] Please continue to refer to Figure 1 and Figure 2 The U-shaped bend of the exhaust section 13 is located in the accommodating space 11, which is beneficial to the effectiveness and efficiency of exhaust.

[0019] Please continue to refer to Figure 1 and Figure 2 The U-shaped notch of the exhaust section 13 is not connected to the accommodating space 11.

[0020] Please continue to refer to Figure 1 and Figure 2 A tear 14 can be provided on one or both sides of the main body 10, which makes it convenient for the user to tear the main body 10 open.

[0021] Please continue to refer to Figure 3 and pair Figure 1It is revealed that an ingredient 19 is filled into the accommodating space 11 of the body 10 through the filling port 12, and the filling port 12 is heat-sealed after filling is completed.

[0022] Please continue to refer to Figure 4 and pair Figure 1 and Figure 2 When the exhaust-capable high-temperature sterilization bag of this application is microwaved, the main body 10 can be placed directly into the microwave space without first tearing the main body 10 to form an opening. During microwave heating, some liquid will be converted into gas, and the gas temperature in the containment space 11 will rise. These changes will cause the volume of the containment space 11 to increase. When the containment space 11 cannot hold more gas, the excess gas will be discharged through the exhaust section 13.

[0023] Please refer to Figure 5 and Figure 6 This invention discloses a high-temperature sterilization bag with venting capability. The main body 10 is formed by overlapping and sealing a first heat-resistant layer 101 and a second heat-resistant layer 102, with a sealing strip 15 formed on each of the two sides. At least one sealing strip 15 is provided with a tear 14 and a through hole 16. The main body 10 has an accommodating space 11, a filling port 12, and an venting part 13. The accommodating space 11 is not connected to the through hole 16. The filling port 12 is located at one end of the main body 10. The venting part 13 is located on the side surface of the main body 10. At least 3 / 5 of the volume of the venting part 13 is located in the accommodating space 11. The side of the venting part 13 facing the main body 10 forms a protrusion. The adjacent area of ​​the venting part 13 and the sealing strip 15 constitutes a sealing area 17. The sealing area 17 is adjacent to the through hole 16 and is not connected to the accommodating space 11. The main body 10 is provided with a through hole 18 at the top. Figure 5 and Figure 6 The difference is that, Figure 5 The exhaust section 13 is generally conical. Figure 6 The exhaust section 13 is rectangular in shape.

[0024] With the above structure, the advantages of this application are as follows:

[0025] 1. High-efficiency exhaust design: The side of the main body 10 is provided with a U-shaped exhaust section 13, and at least 3 / 5 of the volume of the exhaust section 13 is located within the accommodating space 11, ensuring the effectiveness and efficiency of exhaust. When the gas pressure inside the main body 10 increases, excess gas can be discharged through the exhaust section 13, preventing the main body 10 from rupturing and effectively maintaining the stability of the main body 10.

[0026] 2. Avoid false vacuum: By providing through holes 16 to allow gas to enter or flow out, gas pressure can be balanced during the overlapping and sealing process of the first heat-resistant layer 101 and the second heat-resistant layer 102, avoiding twisting or deformation between the first heat-resistant layer 101 and the second heat-resistant layer 102; in addition, it can also reduce the formation of air bubbles during the sealing process, ensure the sealing performance of the first heat-resistant layer 101 and the second heat-resistant layer 102, and improve the sealing quality.

[0027] 3. Microwave-friendly: No need to tear open the body 10 beforehand to create an opening during microwave heating. The body 10 expands during microwave heating, and excess gas can be expelled through the exhaust 13, ensuring the safety of the heating process.

[0028] 4. High temperature resistant design: The body 10 is made of high temperature resistant material to ensure that the body 10 can withstand high temperature environment.

[0029] 5. Convenient filling port 12: One end of the main body 10 is provided with a filling port 12, which makes it convenient to fill food 19 or other items into the containing space 11. The filling port 12 can be heat-sealed after filling to ensure airtightness and hygiene.

[0030] 6. Convenient tear-out design: The main body 10 has a tear-out 14 on one or both sides, which makes it convenient for users to tear the main body 10 open when needed to take out the food 19 or process it further.

[0031] Although this application is illustrated with a preferred embodiment, those skilled in the art can make various modifications without departing from the spirit and scope of this application. The embodiments described above are merely illustrative and not intended to limit the scope of this application. All modifications or alterations made without departing from the spirit of this application are within the scope of this patent application.
