Description

Technical Field

[0001] This utility model relates to the field of liquid packaging, specifically to a liquid packaging bag with an internal straw. Background Technology

[0002] Currently, flexible plastic bags are widely used as the packaging structure for ready-to-drink liquids and are ubiquitous. Existing liquid packaging bags, such as patents CN201458069U and CN2587778Y, disclose a self-standing sealing packaging bag and a self-standing suction-type packaging bag, respectively. In these two patent documents, a groove is provided between the suction end and the upper seal of the bag body. One patent has a tear line on the suction end, and the other has a notch on the outer side of the suction end for easy tearing. The suction end is torn along the tear line or from the notch to expose the straw for convenient drinking. However, during transportation, because there is a groove between the suction end and the upper seal of the bag body, the suction end is easily damaged, leading to leakage and deterioration of the liquid inside the packaging bag. Utility Model Content

[0003] The purpose of this utility model is to provide a liquid packaging bag with a built-in straw, which is not easily damaged, has a simple structure, and is convenient for drinking.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A liquid packaging bag with an internal straw includes a bag body and a straw built into the bag body. The inside of the bag body is heat-sealed to form a liquid-filling cavity. The upper end of the liquid-filling cavity is heat-sealed to form a liquid-filling opening and a drinkable end. The liquid-filling opening is connected to the liquid-filling cavity. After liquid is filled, the liquid-filling opening is sealed by heat sealing. A vertical tear is provided at the connection between the liquid-filling opening and the drinkable end. The upper end of the straw is located inside the drinkable end, and the lower end of the straw extends into the liquid-filling cavity. The drinkable end has a straw hole corresponding to the straw opening. In use, the drinkable end is pulled and torn along the tear, and the drinkable end is pulled and bent away from the straw hole so that the straw opening protrudes from the straw hole.

[0006] As a preferred embodiment, the upper end of the tear is provided with a notch.

[0007] As a preferred embodiment, the lower end of the tear is provided with a U-shaped anti-tear portion.

[0008] As a preferred embodiment, the bottom of the liquid-filling cavity is arc-shaped.

[0009] As a preferred embodiment, the lower end of the straw is close to the bottom of the liquid-filling chamber.

[0010] As a preferred embodiment, the bag body is composed of a multi-layer film structure, which includes a heat-sealing layer, a pressure-bearing layer and a high-temperature resistant layer arranged sequentially from the inside to the outside.

[0011] As a preferred embodiment, the thickness of the heat-sealing layer is 0.012-0.015 μm.

[0012] As a preferred option, the thickness of the pressure-bearing layer is 0.07-0.010 μm.

[0013] As a preferred option, the thickness of the high-temperature resistant layer is 0.080-0.085μm.

[0014] As a preferred embodiment, the heat-sealing layer, the pressure-bearing layer, and the high-temperature resistant layer are made of PET, AL, and PE, respectively.

[0015] The beneficial effects of this utility model are:

[0016] This invention features a tear mark at the heat-sealed area between the liquid filling port and the suction end, and a straw hole on the suction end. Before drinking, the liquid filling port and the suction end are connected and are not easily damaged. When drinking, the suction end is pulled and bent to the side away from the straw hole so that the straw mouth can pass through the straw hole, making it convenient to drink. The structure is simple.

[0017] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments: Attached Figure Description

[0022] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1 As shown, this utility model discloses a liquid packaging bag with a built-in straw 20, including a bag body and a straw 20 built into the bag body. The inside of the bag body is heat-sealed to form a liquid filling cavity 11. The upper end of the liquid filling cavity 11 is heat-sealed to form a liquid filling port 12 and a suction end 13. The liquid filling port 12 is connected to the liquid filling cavity 11. After liquid is filled, the liquid filling port 12 is sealed by heat sealing. A vertical tear 14 is provided at the connection between the liquid filling port 12 and the suction end 13. The upper end of the straw 20 is located inside the suction end 13, and the lower end of the straw 20 extends into the liquid filling cavity 11. The suction end 13 is provided with a straw hole 131 corresponding to the straw opening of the straw 20. In use, the suction end 13 is pulled and torn along the tear 14, and the suction end 13 is pulled and bent to the side away from the straw hole 131 so that the straw opening 20 passes through the straw hole 131. By providing a tear 14 at the heat-sealed area between the liquid filling port 12 and the sippy end 13, and by providing a straw hole 131 on the sippy end 13, the liquid filling port 12 is connected to the sippy end before drinking, making it less prone to breakage. When drinking, the sippy end 13 is pulled and bent to the side away from the straw hole 131 so that the straw opening 131 can be passed through the straw hole 131, making it convenient to drink. The structure is simple.

[0025] To facilitate tearing along the tear line 14, a notch 15 is provided at the upper end of the tear line 14. To prevent tearing of the liquid filling cavity 11 during the tearing process, a U-shaped anti-tear part 16 is provided at the lower end of the tear line 14.

[0026] To facilitate clean drinking, the bottom of the liquid-filling cavity 11 is arc-shaped, and the lower end of the straw 20 is close to the bottom of the liquid-filling cavity 11.

[0027] The bag body 10 is composed of a multi-layer film structure, which includes a heat-sealing layer, a pressure-bearing layer and a high-temperature resistant layer (not shown) arranged sequentially from the inside to the outside. The thickness of the heat-sealing layer is 0.012-0.015μm, the thickness of the pressure-bearing layer is 0.07-0.010μm, and the thickness of the high-temperature resistant layer is 0.080-0.085μm. In this embodiment, the heat-sealing layer, the pressure-bearing layer and the high-temperature resistant layer are made of PET, AL and PE, respectively.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
