Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a wear-resistant packaging bag. Background Technology

[0002] Packaging bags are widely used in daily life for the storage and transportation of food, daily necessities, and other products. Traditional packaging bags are usually made of a single material, which, while possessing a certain degree of wear resistance and sealing, still has shortcomings in practical use.

[0003] For example, existing packaging bags often require the assistance of external funnels to feed powdery or granular materials (such as grains, seasonings, etc.), which makes them inconvenient to use.

[0004] Therefore, we propose a wear-resistant packaging bag. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a wear-resistant packaging bag that facilitates material pouring and improves convenience, effectively solving the problems in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wear-resistant packaging bag, including a packaging bag, a handle installed on the upper part of the packaging bag, a slanted cut on the upper part of the left outer surface of the packaging bag, a sealing assembly installed in the slanted cut, the sealing assembly including a diamond frame, a bag mouth, an internal threaded ring, a knob, a screw and a sealing ring, and the diamond frame is sealed and bonded to the position of the slanted cut.

[0009] Preferably, the packaging bag is made of food-grade PE.

[0010] Preferably, the bag opening is made of food-grade TPU.

[0011] Preferably, the lower outer surface of the bag opening is bonded to the inner wall of the diamond-shaped frame, the internal threaded ring is fixedly installed on the upper outer surface of the bag opening, and the sealing ring is fixedly installed on the upper outer surface of the internal threaded ring.

[0012] Preferably, the screw is fixedly installed on the lower outer surface of the knob.

[0013] Preferably, the screw and the internal threaded ring are connected by a thread.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a wear-resistant packaging bag with the following beneficial effects:

[0016] 1. This wear-resistant packaging bag features an integrated funnel design for easy operation. With its slanted cut and adjustable sealing assembly, it allows for rapid feeding without the need for an external funnel. After removing the knob and screw, pressing the inner threaded ring causes the bag opening to indent and form a funnel-shaped structure, simplifying the filling process and preventing material spillage. It is especially suitable for filling powdery or granular items.

[0017] 2. This wear-resistant packaging bag adopts a threaded knob and internal thread ring design, combined with a sealing ring, to ensure a tight seal of the packaging bag. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] This embodiment is a wear-resistant packaging bag.

[0025] like Figure 1-4 As shown, the packaging bag 1 is provided with a handle 2 on the upper part of the packaging bag 1. A slanted cut 3 is provided on the upper part of the left outer surface of the packaging bag 1. A sealing component 4 is installed in the slanted cut 3. The sealing component 4 includes a diamond frame 5, a bag opening 6, an internal threaded ring 7, a knob 8, a screw 9 and a sealing ring 10. The diamond frame 5 is sealed and bonded to the position of the slanted cut 3.

[0026] The packaging bag 1 is made of food-grade PE; the bag opening 6 is made of food-grade TPU; the lower outer surface of the bag opening 6 is bonded to the inner wall of the diamond frame 5; the internal threaded ring 7 is fixedly installed on the upper outer surface of the bag opening 6; the sealing ring 10 is fixedly installed on the upper outer surface of the internal threaded ring 7; the screw 9 is fixedly installed on the lower outer surface of the knob 8; the screw 9 and the internal threaded ring 7 are connected by threads.

[0027] It should be noted that this utility model is a wear-resistant packaging bag. The packaging bag 1, handle 2, and oblique cut 3 described herein are all prior art. The packaging bag 1 is made of PE material, which is more resistant to puncture and friction and has excellent flexibility. These features are readily available to those skilled in the art and will not be elaborated further. The sealing component 4 and the diamond frame 5 are attached to the oblique cut 3, as shown in the attached instruction manual. Figure 1 As shown, at this time, the bag opening 6 is located at the upper part of the diamond frame 5. When filling, such as filling soybeans, red beans, millet, etc., first turn the knob 8. The knob 8 drives the screw 9 to separate from the internal thread ring 7. Then, squeeze the position of the internal thread ring 7, squeezing the internal thread ring 7 and the bag opening 6 into the lower part of the diamond frame 5, as shown in the instruction manual. Figure 4 As shown, at this time, the bag opening 6 and the inner threaded ring 7 enter the interior of the packaging bag 1, and form a funnel shape at the oblique cut 3, which is convenient for filling materials. Compared with the existing technology, it is more convenient. The bag opening 6 is made of food-grade TPU (compliant with FDA or EU10 / 2011 standards), which is non-toxic and odorless, can directly contact food, and has good flexibility.
