Description

Technical Field

[0001] This invention relates to the field of food packaging technology, and in particular to an auxiliary opening and extrusion assembly device for flexible packaging bags. Background Technology

[0002] Currently, common flexible packaging bags on the market (such as instant noodle seasoning packets, sauce packets, hot pot base packets, and condiment packets) are generally sealed with plastic film. Consumers need to tear open one end of the packaging bag by hand and then squeeze out the contents by hand or with a tool. However, this traditional opening method has the following problems and shortcomings in practical applications: Inconvenient to operate: When opening the packaging bag, consumers need to use both hands to tear it open and squeeze it repeatedly to squeeze out the contents, which is quite cumbersome. This is especially true for semi-solid, paste-like, or viscous contents, which are even more difficult to squeeze out and are easy to get their hands dirty.

[0003] Incomplete extrusion: Due to the soft material and lack of an effective extrusion structure, consumers often find it difficult to completely expel the contents, typically leaving 10% to 30% of the contents inside the bag, resulting in waste. For pre-portioned foods like instant noodles, seasoning residue can affect the final taste and flavor.

[0004] Time-consuming and laborious: It usually takes ordinary consumers 1 to 2 minutes to open and squeeze out a package, while it takes even longer for the elderly, children, people with disabilities or other special groups with weak hand strength, which makes it difficult to meet the requirements of convenience in modern life.

[0005] Hygiene risks: During the squeezing process, the contents can easily come into direct contact with hands, making them dirty. Furthermore, some consumers may place unopened bags directly into hot water to melt them before squeezing, but this could pose a risk of harmful substances migrating from the plastic packaging at high temperatures.

[0006] To address the aforementioned problems, some improvements have been proposed in the prior art. For example, Chinese patent CN201790471U discloses a fork for instant noodles, with slits in the fork to hold the sauce packet and squeeze it out through sliding motion. Another example is Chinese patent CN211168048U, which discloses an instant noodle bag for conveniently squeezing out the seasoning packet, using through holes in a plastic sheet for the seasoning packet to pass through and be squeezed out. However, these solutions all have the following shortcomings: First, the opener and the packaging bag do not form a pre-assembled and fixed structure, requiring consumers to assemble them temporarily, making operation inconvenient; second, they lack an effective anti-drop design, allowing the packaging bag to easily slip off the opener during transportation or use; and third, they cannot achieve simultaneous squeezing of multiple packaging bags or selective use, resulting in poor flexibility.

[0007] Therefore, it is necessary to develop a flexible packaging bag auxiliary opening extrusion assembly device that is simple in structure, easy to operate, ensures thorough extrusion, is hygienic and reliable, and can be adapted to various usage scenarios. Summary of the Invention

[0008] The purpose of this invention is to provide a flexible packaging bag opening and extrusion assembly device, which aims to achieve a quick opening, convenient extrusion, complete emptying and clean and hygienic operating experience for flexible packaging bags, while meeting the diverse needs of single bag use and multi-bag combination use.

[0009] This invention is achieved using the following technical solution: a flexible packaging bag assisted opening extrusion assembly device, including an opener with at least one through-slit; a packaging bag comprising a main body, barrier portions respectively disposed at both ends of the main body, and an easy-tear portion disposed between the barrier portions and the main body; wherein the main body of the packaging bag passes through the through-slit of the opener, and the cross-sectional dimension of the barrier portion is larger than the width of the through-slit, preventing the barrier portion from reversing after passing through the through-slit. In this invention, the barrier portion is made of the same flexible film material as the main body of the packaging bag, and the barrier portion can pass through the through-slit through its own elastic deformation, and elastically recovers to its original cross-sectional dimension after passing through the through-slit, thereby achieving irreversible limiting and fixing after passing through. The elastic deformation capability of this flexible film material allows the cross-section of the barrier portion to temporarily shrink to below the width of the through-slit when subjected to external force, and returns to its original shape after passing through the slit and the external force constraint is released. This allows the packaging bag and the opener to be pre-installed and fixed together to form a combination. When in use, tear open the easy-tear section at the end of the through-slit to open the main body of the packaging bag. Move the opener from one end of the packaging bag to the other end. The main body of the packaging bag moves relative to the through-slit and is squeezed by the edge of the through-slit, and the contents are discharged from the opened main body of the packaging bag.

[0010] Furthermore, when there is only one main body of the packaging bag, the tear-off sections at both ends are used to open the main body of the packaging bag and separate the barrier from the main body of the packaging bag, so that the opener is separated from the packaging bag.

[0011] Furthermore, it also includes multiple packaging bag bodies, the two ends of which are connected to the same set of barrier parts, and the set of barrier parts are inserted into the same through-slit; each packaging bag body and the barrier part are provided with two easy-tear parts, wherein the easy-tear part away from the packaging bag body is used to remove the packaging bag body from the assembly separately without opening the packaging bag body, and the easy-tear part close to the packaging bag body is used to open the packaging bag body to discharge the contents.

[0012] Furthermore, when the contents of a particular packaging bag are no longer needed, the bag can be removed individually by tearing the tear-off section at the far end of the bag, while the remaining packaging bags remain in their combined state with the opener.

[0013] Furthermore, the opener is made of plastic and is a fork-shaped, spoon-shaped, or sheet-like structure.

[0014] Furthermore, the opener is made of food-grade edible material, so that after the contents are discharged, the opener can be soaked or cooked together with the food for consumption.

[0015] Furthermore, the tear-off portion is one or more combinations of dotted line cuts, semi-penetrating indentations, tear strips, and weakening lines.

[0016] Furthermore, the cross-sectional dimension of the barrier is 1.2 to 3 times the width of the through gap.

[0017] The flexible packaging bag assisted opening and extrusion assembly device of the present invention has the following advantages: Easy to operate, time-saving and efficient: This invention combines the opener with the packaging bag in a pre-installed and fixed assembly. When using it, consumers only need to tear open the easy-tear section and slide the opener to squeeze out the contents. The operation steps are simple and the operation time can be shortened to about 10 seconds, saving a lot of time and effort compared with the traditional method.

[0018] Thorough extrusion reduces waste: The edge penetrating the gap applies uniform pressure to the main body of the packaging bag during sliding, which can fully extrude the contents, effectively avoiding waste caused by contents residue and ensuring the flavor consistency of quantitatively formulated products.

[0019] Hygiene and Safety: Throughout the extrusion process, the contents do not come into direct contact with hands, preventing hand contamination. Furthermore, the edible material used for the opener allows it to be consumed after use, eliminating the environmental impact of waste plastics and avoiding the safety hazards of heating plastics at high temperatures.

[0020] Highly adaptable and flexible: This invention can be used independently for single-bag packaging, or multiple bags can be squeezed out simultaneously or selectively by sharing the same set of barriers and the same through-slit, meeting the needs of different consumption scenarios. The shape and material of the opener can be flexibly selected according to actual needs. The plastic material solution is low-cost and can also be used as tableware, while the edible material solution provides a more environmentally friendly and fun experience.

[0021] Simple structure and low cost: This invention only requires adding a barrier and an easy-tear part to the existing packaging bag, and performing a simple slit process on the opener. It does not require changing the overall framework of the existing production process, making it easy to achieve industrialized mass production. It has good economic benefits and promotional value.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0026] Example 1: like Figure 1 As shown, this embodiment provides a flexible packaging bag auxiliary opening extrusion assembly device, which is suitable for single-bag flexible packaging scenarios such as instant noodle sauce packets and hot pot base packets.

[0027] The opener 1 has at least one through slit 11. The width of the through slit 11 is adapted to the thickness and width of the packaging bag body 21, so that the packaging bag body 21 can pass through it.

[0028] The packaging bag 2 includes a main body 21, barrier portions 22 respectively disposed at both ends of the main body 21, and an easy-tear portion 23 disposed between the barrier portions 22 and the main body 21. The cross-sectional dimension of the barrier portion 22 is larger than the width of the through gap 11. Specifically, in this embodiment, the width of the barrier portion 22 is 1.5 times the width of the through gap 11. The easy-tear portion 23 has a dotted cut structure and can be torn off manually.

[0029] Before leaving the factory, the main body 21 of the packaging bag is inserted into the through-slit 11 of the opener 1. Then, the blocking parts 22 at both ends are sequentially inserted into the through-slit 11. Since the blocking parts are made of the same flexible plastic film as the main body of the packaging bag, when they pass through the through-slit, they undergo elastic compression deformation under the squeezing force of the edge of the through-slit, and their cross-section temporarily shrinks to the size that can pass through the slit. After passing through the slit, the squeezing force is released, and the blocking parts elastically return to their original size, achieving a limiting effect that prevents them from falling out in the opposite direction. Since the cross-sectional size of the blocking part 22 is larger than the width of the through-slit 11, the blocking part 22 cannot fall out in the opposite direction after passing through the through-slit 11, thus pre-installing and fixing the packaging bag 2 and the opener 1 to form a combination. At this time, the main body 21 of the packaging bag is located in the through-slit 11, and the blocking parts 22 at both ends are located on both sides of the opener 1, playing a role in axial limiting and preventing falling out.

[0030] In use, the consumer first locates the barrier 22 at the end furthest from the opener 1, tears open the tear-off section 23 at that end, separating the barrier 22 from the main body 21 of the packaging bag. Simultaneously, a discharge port is formed at that end of the main body 21. Then, the consumer holds the opener 1 with one hand and the other end of the main body 21 (closer to the opener 1) with the other, moving the opener 1 from one end of the packaging bag 2 to the other. During this process, the main body 21 moves relative to the through-slit 11, and the edge of the through-slit 11 continuously presses against the main body 21, causing the contents to be discharged from the opened discharge port. When the opener 1 moves to the other end of the main body 21, the tear-off section 23 at that end is torn open again, separating the barrier 22 from the main body 21 as well. At this point, the opener 1 is completely separated from the packaging bag 2, and all the contents are squeezed out.

[0031] Example 2: This embodiment has a structure that is basically the same as that of Embodiment 1, the difference being that the material of the opener 1 is a food-grade edible material. Specifically, the opener 1 is formed by pressing a pasta substrate into a rectangular sheet with a through slit 11 in the center. The pasta substrate can be made from raw materials such as wheat flour and corn starch, and is produced through processes such as cooking, rolling, and drying. It has sufficient strength to complete the extrusion operation, and can be softened and dissolved when exposed to hot water.

[0032] The structure of packaging bag 2 is exactly the same as that of embodiment 1, including packaging bag body 21, end barriers 22 and easy-tear part 23. The pre-installation and fixing method is also the same.

[0033] To use, tear open the tear-off section 23 at the end of the through-slit 11, and move the opener 1 from one end of the packaging bag 2 to the other, squeezing out the contents. After the contents are squeezed out, the opener 1 separates from the packaging bag 2. Since the opener 1 is made of edible material, consumers can place it directly into a food container and cook it along with instant noodles or other foods. The opener 1 softens quickly in hot water without affecting the taste and increases the weight of the food.

[0034] This embodiment is particularly suitable for instant noodle scenarios, as consumers do not need to discard the opener, achieving zero waste.

[0035] Example 3: like Figure 2 As shown, this embodiment provides a combined device in which multiple packaging bag bodies share the same set of barrier parts and the same through-slit, which is suitable for scenarios where multiple seasonings or ingredients need to be added at the same time, such as sauce packets, oil packets, and powder packets for instant noodles.

[0036] like Figure 3 As shown, this embodiment includes an opener 1 and multiple packaging bags 2. The structure of the opener 1 is the same as in embodiment 1, and it has a through slit 11. The two ends of the multiple packaging bag bodies 21 are connected to the same set of barrier portions 22. Specifically, the set of barrier portions 22 includes two barrier portions 22, located at both ends of the multiple packaging bag bodies 21 respectively. Each packaging bag body 21 is provided with two easy-tear portions 23 between it and the barrier portion 22, namely a distal easy-tear portion 23 away from the packaging bag body 21 and a proximal easy-tear portion 23 close to the packaging bag body 21. The distal easy-tear portion 23 is used to remove the packaging bag body 21 from the assembly separately without opening the packaging bag body 21; the proximal easy-tear portion 23 is used to open the packaging bag body 21 to discharge the contents.

[0037] During pre-assembly and fixing, the group of barrier parts 22 are inserted into the same through-slit 11. Since the cross-sectional dimension of the barrier part 22 is larger than the width of the through-slit 11, the barrier part 22 cannot be removed, thereby pre-assembling and fixing all the packaging bag bodies 21 and the opener 1 to form a combination.

[0038] When using the product, consumers can choose one of the following two operating methods as needed: Method 1 (Complete Extrusion): Tear open the distal easy-tear portion 23 at the end of the through-slit 11, separating the barrier portion 22 from all the main packaging bag bodies 21. At this point, all the main packaging bag bodies 21 form an outlet at this end. Then, move the opener 1 from one end of the packaging bag 2 to the other end, and all the main packaging bag bodies 21 are simultaneously squeezed by the through-slit 11, and the contents are discharged from their respective outlets simultaneously. This method is suitable for situations where all ingredients need to be added.

[0039] Method 2 (Selective Bag Removal): If the consumer does not need the contents of a particular bag body 21 (e.g., does not want the spicy seasoning packet), they can simply tear open the distal tear-off portion 23 (the tear-off portion furthest from the bag body 21) to remove that bag body 21 from the assembly without opening it. The remaining bag bodies 21 remain assembled with the opener 1. Then, tear open the proximal tear-off portion 23 of the remaining bag bodies 21 to open the discharge port and move the opener 1 to expel the contents. The removed bag body 21 remains sealed and can be used later.

[0040] In this embodiment, the key design feature is the provision of two tear-off sections 23 between each packaging bag body 21 and the barrier section 22: the distal tear-off section 23 is used for removing the bag (without damaging the seal of the packaging bag body 21), and the proximal tear-off section 23 is used for opening (damaging the seal of the packaging bag body 21). The distance between the two tear-off sections 23 can be adjusted according to the length of the packaging bag body 21, typically 5~15mm.

[0041] Example 4: like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the opener 1 is a fork-shaped structure made of plastic. The fork head of the opener 1 is provided with a through slit 11.

[0042] The structure of packaging bag 2 is the same as that of Example 1. The pre-loading and fixing method and usage method are the same as those of Example 1.

[0043] In this embodiment, the fork-shaped opener 1 can be used as tableware after use, further improving convenience.

[0044] The above embodiments describe the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Modifications and variations made by those skilled in the art without departing from the spirit and scope of the invention should be within the protection scope of the appended claims.
