Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging bag technology, specifically to a food packaging bag with an observation window. Background Technology
[0002] Food packaging bags are containers or materials specifically designed for packaging food. They are primarily used to protect food from external contamination, extend shelf life, facilitate storage and transportation, and also serve functions such as brand display and consumer convenience.
[0003] Currently, to avoid direct sunlight, food packaging bags are generally made of colored film. This prevents consumers from seeing the appearance and type of food inside the bag, affecting their purchasing desire. Furthermore, the lack of a clear view can influence consumers' judgment of the food. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a food packaging bag with an observation window, the packaging bag body is transparent, and the protective bag body can cover the packaging bag body to avoid sunlight exposure, so as to solve the problems mentioned in the background art.
[0005] This utility model is achieved through the following technical solution: a food packaging bag with an observation window, comprising a packaging bag body and a protective bag body. The packaging bag body is at the opening, and the remaining edges are thickened outward to form a sealing edge. The protective bag body is set outside the packaging bag body. The protective bag body is divided into two halves in the middle, and one end of each half bag is heat-pressed and fixed to the packaging bag body. The two sides of each half bag expand inward to form a sealing part, which covers the sealing edge on both sides of the packaging bag body. A sealing element is installed between the sealing parts to fix them together.
[0006] As a preferred technical solution, the sealing element includes a concave strip and a convex strip. The concave strip is embedded and hot-pressed to be fixed on one side of the sealing part, and the convex strip is embedded and hot-pressed to be fixed on the other side of the sealing part. The convex strip is inserted into the concave strip and is fitted and connected with the concave strip.
[0007] As a preferred technical solution, the sealing edge of the packaging bag is provided with multiple positioning holes, and the end face of the sealing part protrudes to form a positioning part opposite to the positioning hole, and the positioning part is inserted into the corresponding positioning hole.
[0008] As a preferred technical solution, the packaging bag is made of transparent PP material.
[0009] As a preferred technical solution, the protective bag is made of black PP material.
[0010] As a preferred technical solution, the sealing parts are all arranged in a "J" shape, and a channel is formed between the sealing parts to match the sealing edge on the packaging bag. The sealing edge of the packaging bag is inserted into the channel and fits against the inner wall of the channel.
[0011] As a preferred technical solution, the edge banding is thickened.
[0012] The beneficial effects of this utility model are: the structure of this utility model is simple. The protective bag can cover the transparent packaging bag. After opening the protective bag, the appearance and type of the food inside can be clearly seen through the transparent packaging bag, which makes it convenient for consumers to distinguish and judge. Furthermore, the protective bag and the packaging bag can provide double protection for the food, which increases safety. At the same time, the protective bag is easy to open and close.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0020] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.
[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a food packaging bag with an observation window, comprising a packaging bag body 1 and a protective bag body. The packaging bag body 1 is located at the opening, and the remaining edges are thickened outward to form a sealed edge. The protective bag body is located outside the packaging bag body 1. The protective bag body is divided into two halves 2 in the middle. One end of each half 2 is heat-pressed and fixed to the packaging bag body 1. The two sides of the half 2 expand inward to form a sealing part 3. The sealing part 3 covers the sealed edges on both sides of the packaging bag body 1. A sealing element 4 is installed between the sealing parts 3 to fix the sealing parts 3 together.
[0023] In this embodiment, the sealing element 4 includes a concave strip and a convex strip. The concave strip is embedded and hot-pressed to be fixed on one side of the sealing part 3, and the convex strip is embedded and hot-pressed to be fixed on the other side of the sealing part 3. The convex strip is inserted into the concave strip and fits into it. This structure is a common pressure strip design. The bag opening is sealed by the fit between the groove and the convex strip. In this case, it fixes the half bag together. This structure also facilitates opening outward and reconnecting the half bag later.
[0024] In this embodiment, the packaging bag body 1 has multiple positioning holes 5 on its sealing edge. The end face of the sealing part 3 protrudes from the positioning hole 5 to form a positioning part 6, and the positioning part 6 is inserted into the corresponding positioning hole 5.
[0025] In this embodiment, the packaging bag 1 is made of transparent PP material, so that the appearance of the food inside can be clearly seen through the packaging bag.
[0026] In this embodiment, the protective bag is made of black PP material, which can block external sunlight.
[0027] In this embodiment, the sealing parts 3 are all arranged in a "J" shape, and a channel matching the sealing edge on the packaging bag body 1 is formed between the sealing parts 3. The sealing edge of the packaging bag body 1 is inserted into the channel and fits against the inner wall of the channel. The sealing parts can better clamp the sealing edge, and the combination of the positioning part and the positioning hole can position the protective bag body, increasing the stability after installation.
[0028] In this embodiment, the edge sealing is thickened, which increases the strength of the edge sealing and reduces the probability of the packaging bag edge breaking.
[0029] The protective bag covers the transparent packaging, preventing sunlight from passing through and contacting the packaging, thus providing a light-blocking effect. When consumers make purchases, they can pull out half of the bag, allowing the raised strip on one half to emerge from the recessed strip, exposing the entire packaging. Through the open half, consumers can fully see the appearance and type of the food inside, facilitating their judgment.
[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
