Description

Technical Field

[0001] This utility model belongs to the field of drip coffee technology, specifically relating to drip coffee filter bags. Background Technology

[0002] Drip coffee filter bags have become a popular coffee brewing method in today's fast-paced lifestyle due to their convenience and ability to be brewed without special equipment. Their core design involves hanging the filter bag on both sides of the cup, allowing the coffee grounds to fully contact and extract the coffee from the hot water. However, existing drip coffee filter bags still have the following problems in practical use, affecting the brewing experience and stability.

[0003] First, traditional drip coffee filter bags typically have simple sheet or strip-shaped loops, with the connection point concentrated in a single area, resulting in limited support strength. When hot water is poured into the filter bag, the coffee grounds absorb water and expand, increasing the bag's weight. This uneven stress can cause the loops to deform, leading to the filter bag tilting to one side or even tipping over, causing coffee leakage and contamination of the cup. Furthermore, the small contact area between the loop and the cup rim, coupled with a lack of restraint mechanisms, means that even a slight touch during brewing can cause the loop to slip off the cup, further compromising safety.

[0004] In addition, the existing drip bag has poor stability in its folded shape, making it difficult to maintain the preset angle after unfolding. The conical opening at the top of the filter bag is prone to closing due to insufficient support, resulting in hot water not being able to penetrate the coffee powder evenly, leading to uneven extraction and flavor imbalance.

[0005] Furthermore, the bonding between the drip bag and the filter bag is often a straight line or a single connection segment, which is prone to delamination under long-term stress, reducing the overall structural strength of the filter bag and shortening its lifespan. These issues make it difficult for drip bag coffee filter bags to balance convenience with stability and brewing quality. There is an urgent need to optimize the structure to improve the support performance, connection strength, and compatibility with the cup, in order to solve the problems of unstable support, easy slippage, and uneven extraction found in existing products. Utility Model Content

[0006] To address the above problems, the purpose of this utility model is to provide a drip bag coffee filter bag that solves the problems of insufficient drip support strength, poor compatibility with cup body and easy slippage, weak stability of folded shape leading to uneven extraction, and easy delamination of adhesive parts in existing drip bag coffee filter bags.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a hanging-ear coffee filter bag, comprising:

[0008] The filter bag has two hanging ears, which are positioned opposite each other on both sides. The top opening of the filter bag forms a conical bag structure when unfolded. The hanging ears are cut and divided into sections, forming an adhesive part, an extension part, and a hanging part.

[0009] The adhesive part is bonded to the filter bag. The adhesive part includes a middle connecting part and an upper connecting part and a lower connecting part that are respectively connected to the upper and lower ends of the middle connecting part.

[0010] The extension portion, the bottom end of which connects to the bottom ends of the intermediate connecting portion and the lower connecting portion,

[0011] A suspension portion is located between the extension portion and the adhesive portion, and the top end of the suspension portion is connected to the top end of the extension portion.

[0012] The beneficial effects of this utility model are as follows: the extension part, as a transition part, expands the upper side of the upper connecting part while simultaneously expanding and deforming the lower side of the hanging part, thereby enabling the hanging ear to stably support the opened filter bag and hang it stably in the cup body; the use of the adhesive part and the lower connecting part further improves the stability of the hanging ear's support for the filter bag and the adhesive strength.

[0013] In order to effectively improve the stability of the ear loops supporting the filter bag;

[0014] As a further improvement to the above technical solution: the upper connecting part has an inverted "U" shape, and the top end of the middle connecting part is connected to the middle end of the adhesive part.

[0015] The beneficial effects of this improvement are: the two sides of the upper connecting part can stably support the sides of the filter bag, ensuring the stability of the hanging ears supporting the upper part of the filter bag.

[0016] To further improve the stability of the ear loops in supporting the filter bag;

[0017] As a further improvement to the above technical solution: the number of the lower connecting parts is two and they are arranged opposite each other on both sides of the middle connecting part, and the lower connecting parts are inclined from bottom to top in the direction away from the middle connecting part.

[0018] The beneficial effects of this improvement are: the lower connecting part can stably support the sides of the filter bag, ensuring the stability of the hanging ears' support for the lower half of the filter bag.

[0019] In order to effectively improve the stability of the suspension part on the cup body;

[0020] As a further improvement to the above technical solution: the left and right inner sides of the suspension part are protruding and formed with opposing limiting parts.

[0021] The beneficial effects of this improvement are as follows: by folding the hanging part outward to open the opening, the hanging part set on the hanging ears on both sides of the filter bag can be mounted on the cup mouth. At this time, the protruding limiting part is folded in the direction of the extension part so that when the weight of the water injected into the filter bag increases and the hanging part slides down, it is supported on the top of the cup mouth, which further improves the stability of the hanging part mounted on the cup body.

[0022] In order to maintain the stability of the folded shape between the suspension part and the extension part;

[0023] As a further improvement to the above technical solution: the connection between the suspension part and the extension part is embossed with a crease line extending downwards.

[0024] The beneficial effects of this improvement are: after folding, a fixed crease memory is formed at the crease line, which can maintain the folding shape between the hanging part and the extension part for a long time, making it less prone to deformation due to external forces and improving the overall support.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] Example 1:

[0033] like Figure 1 —As shown in Figure 4: Drip bag coffee filter bags, including:

[0034] Two hanging ears 2 are arranged opposite each other on both sides of the filter bag 1. The top opening of the filter bag 1 forms a conical bag structure when unfolded. The hanging ears 2 are cut and divided into sections with an adhesive part 10, an extension part 6, and a hanging part 7.

[0035] The adhesive part 10 is bonded to the filter bag 1. The adhesive part 10 includes a middle connecting part 4 and an upper connecting part 3 and a lower connecting part 5 connected to the upper and lower ends of the middle connecting part 4, respectively.

[0036] Extension 6, the bottom end of which connects to the bottom ends of the intermediate connecting part 4 and the lower connecting part 5.

[0037] The suspension part 7 is located between the extension part 6 and the adhesive part 10. The top end of the suspension part 7 is connected to the top end of the extension part 6. The extension part 6 acts as a transition part, allowing the upper side of the upper connecting part 3 to expand outward while simultaneously deforming the lower part of the suspension part 7 outward. This allows the hanging ear 2 to stably support the opened filter bag 1 and securely hang it in the cup body. The use of the adhesive part 10 and the lower connecting part 5 further improves the stability of the hanging ear 2 in supporting the filter bag 1. The upper connecting part 3 has an inverted "U" shape. The top end of the middle connecting part 4 is connected to the middle end of the adhesive part 10. The two sides of the upper connecting part 3 can stably support the sides of the filter bag 1, ensuring the stability of the hanging ear 2 in supporting the upper part of the filter bag 1. There are two lower connecting parts 5, which are arranged opposite each other on both sides of the middle connecting part 4. The lower connecting parts 5 extend from bottom to top away from the middle. The connecting part 4 is inclined, and the lower connecting part 5 can stably support the side of the filter bag 1, ensuring the stability of the hanging ear 2 supporting the lower half of the filter bag 1. The left and right inner sides of the suspension part 7 are protruding with oppositely arranged limiting parts 9. When the suspension part 7 is folded outward to open the opening, the suspension part 7 on the hanging ear 2 on both sides of the filter bag 1 can be mounted on the cup mouth. At this time, the protruding limiting part 9 is folded towards the extension part 6 so that when the weight of the suspension part 7 increases due to the water filling in the filter bag 1 and causes it to slide down, it is supported at the top of the cup mouth, further improving the stability of the suspension part 7 mounted on the cup body. The connection between the suspension part 7 and the extension part 6 extends downward and is pressed with a crease line 8. After folding, a fixed crease memory is formed at the crease line 8, so that the folding shape between the suspension part 7 and the extension part 6 can be maintained for a long time and is not easily deformed by external forces, thus improving the overall support.

[0038] The working principle of this technical solution is as follows: Pinch the ear loops on both sides of the filter bag with both hands and stretch outward along the connection edge between the ear loop and the filter bag. At this time, the crease line 8 on the ear loop plays a role, guiding the suspension part 7 and the extension part 6 to fold and unfold naturally along the crease. Since the bottom end of the extension part 6 is connected to the middle connection part 4 and the lower connection part 5, during the stretching process, the extension part 6 acts as a transition structure, driving the upper side of the upper connection part 3 to expand outward while causing the lower part of the suspension part 7 to expand and deform outward simultaneously, forming a stable support angle. The inverted "U" shaped structure of the upper connection part 3 will open naturally, with both sides fitting the sides of the upper half of the filter bag. The lower connection part 5 unfolds outward due to the inclined setting, supporting the lower half of the filter bag, ensuring that the conical opening at the top of the filter bag is fully opened, leaving sufficient space for subsequent water injection.

[0039] The unfolded hanging part 7 is placed on both sides of the cup mouth, ensuring that the two sides of the hanging part 7 are symmetrically distributed and the force is balanced. At this time, the limiting part 9 on the left and right inner sides of the hanging part 7 is in a natural state and in contact with the edge of the cup mouth. Press the hanging part 7 lightly to make it fit tightly with the cup mouth. Then fold the limiting part 9 towards the extension part 6. Utilize the shaping effect of the crease line 8 to make the limiting part 9 perpendicular to the hanging part 7 and fit the top of the cup mouth. The protruding structure of the limiting part 9 can effectively hold the edge of the cup mouth and prevent the filter bag from sliding down due to the increased weight after water is added, further improving the suspension stability.

[0040] Hot water is slowly poured into the conical opening at the top of the filter bag. The water flows along the inner wall of the filter bag and penetrates into the coffee powder. Because the filter bag is stably supported by the ear loops, the conical opening remains open, and the hot water can evenly cover the surface of the coffee powder, avoiding uneven extraction caused by local accumulation. During the water pouring process, the inverted "U"-shaped structure of the upper connecting part 3 continuously supports the upper part of the filter bag, while the lower connecting part 5 distributes the weight of the lower part of the filter bag by tilting. The multi-segment connection of the adhesive part 10 ensures the connection strength between the ear loops and the filter bag, preventing delamination due to water flow impact or increased weight.

[0041] After brewing, wait for the coffee liquid to drip completely into the cup, hold the extension 6 of the two side handles with both hands, lift the filter bag upwards, and discard the used filter bag along with the coffee grounds, or dispose of it according to the garbage classification requirements.
