Description

Technical fields:

[0001] This utility model belongs to the field of bra packaging bags in the field of clothing packaging accessories, specifically relating to a packaging bag suitable for vacuum packaging of bras. Background technology:

[0002] As society develops, the packaging of bras and clothing has been gradually upgraded. Vacuum packaging of clothing can effectively prevent bacterial growth and improve the hygiene of clothing. In particular, close-fitting bras need to be vacuum packaged. However, the vacuum packaging bags currently used for bras still use the common flat film bag body. Since the molded cups of bras contain sponge, the molded cups do not have ideal resilience after compression. Therefore, it is necessary to improve the bag body. Summary of the Invention:

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a packaging bag suitable for vacuum packaging of bras that can overcome the above-mentioned shortcomings.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a packaging bag suitable for vacuum packaging of bras, the key being that the packaging bag includes a packaging film of a preset length unit, the packaging bag is a strip-shaped bag with a double-layer structure and an opening at one end, and the packaging film of the preset length unit is provided with two hemispherical protrusions corresponding to the bra cups.

[0005] A packaging bag suitable for vacuum packaging of bras, the key feature of which is that the packaging bag includes a series of packaging films of multiple preset length units, the packaging bag is a strip-shaped bag with a double-layer structure and openings at both ends, and each preset length unit of packaging film is provided with two hemispherical protrusions corresponding to the bra cups.

[0006] The preset length unit is a packaging bag length that is one or two times the width of the human chest cavity.

[0007] The preset length unit of the packaging film is the length of the packaging bag, which is one times the width of the human chest cavity. The two hemispherical protrusions are located in the middle of the packaging film and are suitable for packaging bras in the fastened state.

[0008] The preset length unit of the packaging film is twice the width of the human chest cavity, and the two hemispherical protrusions are located in the middle of the packaging film, which is suitable for packaging bras with back clasp type in the unfolded state.

[0009] The preset length unit of the packaging film is twice the width of the human chest cavity, and the two hemispherical protrusions are respectively set at both ends of the packaging film, which is suitable for packaging bras with front clasp type in the unfolded state.

[0010] Each preset length unit of the packaging film is the length of a packaging bag that is one times the width of a human chest cavity, with a length of 40 to 70 cm.

[0011] Each preset length unit of the packaging film is twice the width of a human chest cavity, with a length of 70-120cm.

[0012] A transition protrusion is provided between the two hemispherical protrusions corresponding to the bra cups.

[0013] One of the layers in the double-layer structure has a hemispherical protrusion, and the other layer is a plane.

[0014] This utility model discloses a packaging bag suitable for vacuum packaging of bras. The bag body is pre-made with protrusions that fit the shape of the bra cups according to the position and size of the bra cups. This makes the deformation of the bra cups less during the vacuuming process, thereby reducing the defect of poor recovery of the bra cups after the vacuum packaging is removed due to the shrinkage of the packaging bag film. It has the advantages of being easy to use and effectively improving the packaging quality. Attached image description:

[0017] Figure 3 This is a schematic diagram of another embodiment of the present invention.

[0018] Figure 4 This is a schematic diagram of two other embodiments of the present invention. Detailed implementation method:

[0019] like Figures 1 to 4 As shown, a packaging bag suitable for vacuum packaging of bras is characterized by the fact that the packaging bag includes a packaging film 1 of a preset length unit. The packaging bag is a strip-shaped bag with a double-layer structure and an opening at one end. The packaging film of the preset length unit is provided with two hemispherical protrusions 2 corresponding to the bra cups.

[0020] A packaging bag suitable for vacuum packaging of bras is disclosed. The packaging bag comprises a series of pre-defined length units of packaging film 1. The packaging bag is a strip-shaped bag with a double-layer structure and openings at both ends. Each pre-defined length unit of packaging film has two hemispherical protrusions 2 corresponding to the bra cups. To improve hygiene, it is necessary to use mechanical equipment for automatic bag opening, cutting, feeding, and vacuuming. The series of pre-defined length units of packaging film are suitable for packaging using mechanical equipment. The hemispherical protrusions in the double-layer structure of the packaging bag can be identical or inconsistent; preferably, the height of the protrusions on the bottom layer film is half the height of the protrusions on the top layer film.

[0021] like Figure 1 As shown, the preset length unit is a packaging bag length that is one or two times the width of the human chest cavity. Currently, bras on the market have front-closure and back-closure types, therefore, when unfolded, the molded cups are positioned differently, located at both ends and the middle of the packaging film, respectively.

[0022] The preset length unit of the packaging film 1 is the length of the packaging bag, which is one times the width of the human chest cavity. The two hemispherical protrusions 2 are located in the middle of the packaging film and are suitable for packaging bras in the fastened state.

[0023] like Figure 2 As shown, the preset length unit of the packaging film is twice the width of the human chest cavity, and the two hemispherical protrusions are located in the middle of the packaging film, which is suitable for packaging bras in the unfolded state with a back clasp.

[0024] like Figure 3 As shown, the preset length unit of the packaging film is twice the width of the human chest cavity, and the two hemispherical protrusions are respectively set at both ends of the packaging film, which is suitable for packaging bras in the unfolded state with front clasp.

[0025] Each preset length unit of the packaging film is the length of a packaging bag that is one times the width of a human chest cavity, with a length of 40 to 70 cm.

[0026] Each preset length unit of the packaging film is twice the width of a human chest cavity, with a length of 70-120cm.

[0027] When the two hemispherical protrusions are positioned in the middle of the packaging film, a transition protrusion is provided between the two hemispherical protrusions corresponding to the bra cup.

[0028] One of the layers in the double-layer structure has a hemispherical protrusion, and the other layer is a plane.

[0029] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
