Technical Field
[0001] The utility model relates to the technical field of retort packaging bags, in particular to a set-type retort packaging bag. Background Art
[0002] The main reason for food spoilage is the growth of bacteria and microorganisms. In order to preserve food for a long time, strict sterilization is usually carried out. Steaming and sterilization is the most common method. The packaging of these foods is called steaming and boiling packaging bags. However, this type of packaging bag is easily damaged during transportation, causing the food in the packaging bag to deteriorate, or it cannot be reheated, making the packaging bag lose its function. Moreover, packaging bags generally cannot be placed upright. When transporting or storing, they can only be stacked, which causes the packaging bags to be squeezed and easily deformed and damaged.

[0004] According to the utility model, a set-type cooking packaging bag is proposed, comprising an outer jacket bag, a cooking packaging bag and a trumpet-shaped support bag, the bottom and top of the cooking packaging bag are respectively provided with a first hot-pressed edge seal and a second hot-pressed edge seal, the cooking packaging bag is hot-pressed with a label tape at the middle position of the second hot-pressed edge seal at the top, the top opening of the trumpet-shaped support bag is sleeved on the bottom edge of the cooking packaging bag and is hot-pressed on the cooking packaging bag below the first hot-pressed edge seal, the trumpet-shaped support bag is inserted from the bottom of the outer jacket bag and the bottom edge of the trumpet-shaped support bag is hot-pressed around the bottom edge of the outer jacket bag to form an annular hot-pressed edge, a sealing strip is provided on the inner side of the top opening of the outer jacket bag, and a plurality of circles of hemispherical protrusions are provided on the inner wall of the outer jacket bag.
[0005] In some embodiments of the present invention, a handle extending upward is provided at the middle position of the front and rear sides of the top pocket opening of the outer jacket pocket 1 .
[0006] In some other embodiments of the present invention, the outer bag is heat-pressed and sealed at the opening edge above the sealing strip.
[0007] In some other embodiments of the present invention, the circumference of the outer bag wall is 1.2-1.5 times the circumference of the cooking packaging bag wall.
[0008] In other embodiments of the utility model, during steaming, water is firstly put into the outer bag, the air is exhausted, and then the top opening of the outer bag 1 is sealed with the sealing strip.
[0009] In some other embodiments of the present invention, the thickness of the trumpet-shaped support bag is 3-5 times the thickness of the outer jacket bag, and the thickness is 3-5 mm.
[0010] In the utility model, an outer bag is arranged outside the retort packaging bag, a certain amount of air is filled into the outer bag and then sealed, so that the inner retort packaging bag can be protected during transportation and storage. When heating is required, the outer bag is opened, water is filled into the outer bag and air is exhausted, so that after heating, the hot water in the bag can still keep the retort packaging bag warm, thereby reducing the cooling speed of the retort packaging bag.

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0019] Reference Figure 1-4A set-type cooking packaging bag comprises an outer jacket bag 1, a cooking packaging bag 3 and a trumpet-shaped support bag 2, wherein the bottom and top of the cooking packaging bag 3 are respectively provided with a first hot-pressed edge seal 31 and a second hot-pressed edge seal 32, and the cooking packaging bag 3 is hot-pressed with a label tape 33 at the middle position of the second hot-pressed edge seal 32 at the top, the top opening of the trumpet-shaped support bag 2 is sleeved on the bottom edge of the cooking packaging bag 3 and is hot-pressed on the cooking packaging bag 3 below the first hot-pressed edge seal 31, the trumpet-shaped support bag 2 is inserted from the bottom of the outer jacket bag 1 and the bottom edge of the trumpet-shaped support bag 2 is hot-pressed with the bottom edge of the outer jacket bag 1 to form an annular hot-pressed edge 11, a sealing strip 12 is provided on the inner side of the top opening of the outer jacket bag 1, and a plurality of hemispherical protrusions 13 are provided on the inner wall of the outer jacket bag.
[0020] First, put the food into the steam-cooking packaging bag 3, and heat-press and seal the upper and lower sides to form a first heat-pressed sealed edge 31 and a second heat-pressed sealed edge 32. Sterilize the steam-cooking packaging bag 3 by steaming. After sterilization, put the top opening of the trumpet-shaped support bag 2 on the steam-cooking packaging bag 3 below the first heat-pressed sealed edge 31 and heat-press to form a sealed edge 21 at the opening. Then, insert the steam-cooking packaging bag 3 from the bottom of the outer bag 1, so that the bottom edge of the trumpet-shaped support bag 2 and the bottom edge of the outer bag 1 are heat-pressed to form a circular heat-pressed edge 11, and a sealing strip 12 is provided on the inner side of the top opening of the outer bag 1, which can be squeezed and sealed by hand.
[0021] During the manufacturing process of the outer bag 1, a raised hemispherical protrusion is formed on the inner wall to prevent the outer bag 1 from contacting with the cooking packaging bag 3. When the outer bag 1 is squeezed or punctured by the outside, it plays a buffering and protective role and will not damage the cooking packaging bag 3.
[0022] A carrying strap 10 extending upward is provided at the middle position of the front and rear sides of the top of the outer bag 1, so as to facilitate taking.
[0023] The outer bag 1 is heat-pressed and sealed at the opening edge above the sealing strip 12. The sealing strip 12 may leak and have poor sealing, so heat-pressing and sealing are performed to improve the sealing performance.
[0024] The perimeter of the outer bag 1 is 1.2-1.5 times the perimeter of the wall of the retort packaging bag 3, so that the retort packaging bag 3 can be moved inside the outer bag 1.
[0025] During cooking, water is firstly filled into the outer bag 1, air is exhausted, and then the top opening of the outer bag 1 is sealed with the sealing strip 12. When the food needs to be heated again, the edge of the opening above the sealing strip 12 is cut off and heat-sealed, the outer bag 1 is opened, water is filled in, air is exhausted, and heating is performed. After the air is exhausted, water is filled in, so that the heat outside the outer bag 1 is transferred to the inside of the cooking packaging bag 3.
[0026] The thickness of the trumpet-shaped support bag 2 is 3-5 times the thickness of the outer bag 1, and the thickness is 3-5 mm. The trumpet-shaped support bag 2 plays a certain supporting role and needs to have a certain thickness so that it can be placed upright without bending.
[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
