Description

Technical Field

[0001] This application relates to the technical field of stand-up pouches, and in particular to a bullseye straw-inserting stand-up pouch. Background Art

[0002] A stand-up pouch is a special type of soft packaging bag that has the function of standing on its own, that is, it can stand by itself without a support. This type of bag is usually made of plastic or a composite material of plastic and paper, and has good sealing and protective properties, and is commonly used for packaging products such as food, beverages, and cosmetics.

[0003] The existing Chinese patent with the publication number CN218663165U discloses a food packaging stand-up pouch with eating tools, including a food packaging bag and an eating tool bag; the eating tool bag is connected to the top of the food packaging bag; wherein: the bottom of the food packaging bag is enclosed into an ellipse to vertically support the food packaging bag; the eating tool bag contains eating tools and cleaning supplies; the eating tool bag is connected to the food packaging bag through a tear line; a sealing zipper is provided below the tear line, and a first tear opening is provided at the end of the tear line.

[0004] The above-mentioned food packaging stand-up pouch with eating tools is connected to the food packaging bag through a tear line, and the eating tool bag contains eating tools and cleaning supplies, which increases the functions of the food packaging bag, and has a simple structure, is practical and convenient, provides convenience for users, and is suitable for production and use. However, the above-mentioned food packaging stand-up pouch with eating tools still has some disadvantages, such as: during use, first tear the food packaging bag through the tear line, then move the sealing zipper to open the opening of the food packaging bag, and finally insert the straw into the packaging bag through the opening of the packaging bag. Since there is a large gap between the straw and the packaging bag, when there is a lot of liquid in the bag and the user sucks the liquid in the bag, squeezing the packaging bag will cause the liquid to easily overflow, which is inconvenient to use and needs to be improved. Summary of the Utility Model

[0005] The purpose of this application is to provide a bullseye straw-inserting stand-up pouch to reduce liquid spillage.

[0006] A bullseye straw-inserting stand-up pouch provided by this application adopts the following technical solutions: including a support film and two interconnected composite films, both of the two composite films are connected to the support film, the support film and the two composite films enclose a containing cavity, and one of the composite films includes a through layer and a puncture layer connected to the through layer, the through layer is provided with a through area, and the through area penetrates the through layer.

[0007] By adopting the above technical solution, during the use of the stand-up pouch, one end of the straw passes through the passing area and punctures the easy-to-puncture layer, so that one end of the straw extends into the stand-up pouch. The outer peripheral surface of the straw is in close contact with the inner wall of the punctured hole, and the gap between the straw and the easy-to-puncture layer is small. When the stand-up pouch is squeezed, the liquid is not easily discharged from the gap between the straw and the easy-to-puncture layer, thereby reducing liquid spillage.

[0018] Optionally, the passing layer includes a polyester layer and an aluminum oxide PET layer connected to the polyester layer. The easy-to-puncture layer is a polyethylene layer. The aluminum oxide PET layer is located between the polyester layer and the polyethylene layer. The aluminum oxide PET layer is connected to the polyethylene layer. The passing area penetrates through the polyester layer and the aluminum oxide PET layer.

[0019] By adopting the above technical solution, the aluminum oxide PET layer serves as a barrier layer, playing the role of blocking oxygen and blocking moisture, thereby extending the shelf life of the things in the stand-up pouch. The aluminum oxide PET film also has high thermal stability.

[0020] Optionally, the through layer is a polyester layer, the puncturable layer includes an aluminum foil layer and a polyethylene layer connected to the aluminum foil layer, the aluminum foil layer is located between the polyester layer and the polyethylene layer, the polyester layer is connected to the aluminum foil layer, and the through area penetrates the polyester layer.

[0021] By adopting the above technical solution, the aluminum foil layer serves as a barrier layer, playing the role of blocking oxygen and moisture, thereby extending the shelf life of the contents in the stand-up bag. The aluminum foil layer can reflect ultraviolet rays, protecting the product from damage by ultraviolet rays; the aluminum foil layer can inhibit the growth of bacteria, maintaining the freshness, hygiene and safety of food.

[0022] Optionally, a self-sealing strip for sealing the accommodation cavity is connected between the two composite films, and the self-sealing strip is located at one end of the composite film away from the support film.

[0023] By adopting the above technical solution, when the user needs to pour out the solid or liquid in the stand-up bag, the design of the self-sealing strip allows the user to easily open and close the stand-up bag without additional sealing tools, which is more convenient.

[0024] Optionally, a reserved cavity is formed between the two composite films, the self-sealing strip is located between the accommodation cavity and the reserved cavity, the self-sealing strip is used to separate the accommodation cavity from the reserved cavity, and the composite film is provided with a tear opening corresponding to the reserved cavity.

[0025] By adopting the above technical solution, the reserved cavity is exposed only when the stand-up bag is torn open through the tear opening, thereby preventing dust from entering the stand-up bag.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. During the use of the stand-up bag, one end of the straw passes through the through area and punctures the puncturable layer, so that one end of the straw extends into the stand-up bag. The outer peripheral surface of the straw is in close contact with the inner wall of the punctured hole, and the gap between the straw and the puncturable layer is small. When the stand-up bag is squeezed, the liquid is not easily discharged from the gap between the straw and the puncturable layer, thereby reducing liquid spillage.

Detailed implementation manners

[0039] The following further elaborates on the present application in conjunction with the attached Figure 1 - attached Figure 8 and provides a more detailed description.

[0040] Embodiments of the present application disclose a self-standing bag with a bullseye inserted straw.

[0041] In conjunction with Figure 1 and Figure 2 as shown, it includes a support film (not shown in the drawings) and two interconnected composite films 1. The two composite films 1 are connected by heat sealing, and one end of the two composite films 1 close to the support film is also connected to the support film by heat sealing. The support film and the two composite films 1 enclose an accommodation cavity 2. A self-sealing strip 3 for sealing the accommodation cavity 2 is fixedly connected between the two composite films 1, and the self-sealing strip 3 is located at the end of the composite film 1 away from the support film. One of the composite films 1 includes a through layer 11 and a puncture layer 12 fixedly connected to the through layer 11. The through layer 11 is on the outside and the puncture layer 12 is on the inside. The through layer 11 is provided with a through area 4 that penetrates through the through layer 11. The through area 4 is a cross-shaped dotted line 41, and the dotted line 41 is located between the self-sealing strip 3 and the support film. The other composite film 1 also includes a through layer 11 and a puncture layer 12, and this through layer 11 does not need to be provided with a through area 4.

[0042] Combined Figure 1 and Figure 2 As shown, the through layer 11 includes a polyester layer 111 and an aluminum oxide PET layer 112 connected to the polyester layer 111 by heat sealing. The easy-to-puncture layer 12 is a polyethylene layer 121. The aluminum oxide PET layer 112 is located between the polyester layer 111 and the polyethylene layer 121, and the aluminum oxide PET layer 112 is connected to the polyethylene layer 121 by heat sealing. The polyester layer 111 is on the outside and the polyethylene layer 121 is on the inside. Since the aluminum oxide PET layer 112 is not easily punctured, the dotted line 41 penetrates through the aluminum oxide PET layer 112.

[0043] The implementation principle of a bullseye straw-inserting self-standing bag in an embodiment of the present application is as follows:

[0044] During the use of the self-standing bag, one end of the straw punctures the dotted line 41 and the easy-to-puncture layer 12, so that one end of the straw extends into the self-standing bag. The outer peripheral surface of the straw is in close contact with the inner wall of the punctured hole, and the gap between the straw and the easy-to-puncture layer 12 is small. When the self-standing bag is squeezed, the liquid is not easily discharged from the gap between the straw and the easy-to-puncture layer 12, thereby reducing liquid spillage.

[0045] Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 is that, as Figure 3 shown, the through layer 11 is a polyester layer 111, and the easy-to-puncture layer 12 includes an aluminum foil layer 122 and a polyethylene layer 121 connected to the aluminum foil layer 122 by heat sealing. The aluminum foil layer 122 is located between the polyester layer 111 and the polyethylene layer 121, and the polyester layer 111 is connected to the aluminum foil layer 122 by heat sealing. Since the aluminum foil layer 122 is easily punctured, the dotted line 41 does not need to penetrate through the aluminum foil layer 122.

[0047] Embodiment 3

[0048] The difference between this embodiment and Embodiment 1 is that, as Figure 4 shown, the through area 4 is a dotted line 41 in a cross shape.

[0051] Embodiment 5

[0052] The difference between this embodiment and Embodiment 1 is that, as Figure 6 shown, the through area 4 is a through groove 42 in a cross shape.

[0053] Embodiment 6

[0054] The difference between this embodiment and Embodiment 1 is that, as Figure 7 shown, the through-hole 43 is formed in the area 4.

[0055] Embodiment 7

[0056] The difference between this embodiment and Embodiment 1 is that, as Figure 8 shown, a reserved cavity 5 is formed between the composite films 1, the self-sealing strip 3 is located between the accommodating cavity 2 and the reserved cavity 5, the self-sealing strip 3 is used to separate the accommodating cavity 2 from the reserved cavity 5, the composite film 1 is provided with a tear opening 6 corresponding to the reserved cavity 5, and the tear opening 6 penetrates through the two layers of the composite film 1.

[0057] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
