Description

Technical Field

[0001] This utility model relates to a bag, a stacked structure, and a bag assembly. Background Technology

[0002] Bags are commonly used for packaging or containing items. They have many uses, with common applications including as garbage bags. To facilitate production and transportation, bags are usually connected end-to-end; that is, the bottom of one bag connects to the opening of another, forming a strip. These strips are typically rolled up for storage, forming a bag roll. To use them, the roll is pulled out, one bag is torn off, and the bag can then be used to contain items or garbage.

[0003] Chinese patent ZL202010037393.9 discloses a bag in which the perforations on one side wall of the bag are offset from those on the other side wall, allowing one side of the bag to be hung on a bag fixing device through the perforations. When individual garbage bags need to be separated, they are pulled off the fixing posts one by one, eliminating the need for the traditional method of tearing the garbage bag roll. Furthermore, the first garbage bag at the front of the stack can be easily opened without affecting other garbage bags behind it, making it more convenient to use than traditional rolled garbage bags. It is also suitable for garbage bins with automatic bag-opening functions, allowing the garbage bags to be automatically opened inside the bin.

[0004] The drawback of this type of bag is that the perforation is connected to the internal storage space. When the perforation is located near the middle or bottom of the bag, liquid garbage, small particles, or dust can easily leak out, soiling surrounding items and the environment. Summary of the Invention

[0005] The purpose of this utility model is to provide a bag, a stacked structure, and a bag assembly that can solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: This utility model provides a bag, including a bag body, which includes a front bag face, a rear bag face, a left bag face, a right bag face, and a bottom face. The front bag face, left bag face, rear bag face, right bag face, and bottom face form an accommodating space with an opening at the top. The left bag face and right bag face are foldable and disposed between the front bag face and the rear bag face. The two sides of the rear bag face extend outward with rear extension edges that are not connected to the accommodating space. Each rear extension edge is provided with a fixing hole through which a bag-fixing protrusion can pass, so that the bag opening side and the bag bottom side of the bag body are positioned at multiple locations.

[0007] Preferably, the front side of the bag is provided with multiple pick-up parts and is evenly distributed on both sides of the front side of the bag, so that the bag opening side and the bag bottom side of the front side of the bag can be picked up by multiple parts.

[0008] Preferably, the two sides of the front bag surface extend outward to form front extension edges that are opposite to the rear extension edges and not connected to the receiving space. Each front extension edge is provided with the pickup part, and the front extension edge is also provided with a clearance area that corresponds one-to-one with the fixing hole and allows the bag fixing protrusion to pass through.

[0009] Preferably, the clearance area is a clearance hole, the diameter of which is larger than the outer diameter of the fixed bag protrusion, or the clearance hole has a notch on its edge. Alternatively, the avoidance area is an avoidance buttonhole, the diameter of which, when opened, is larger than the outer diameter of the fixed bag protrusion.

[0010] Preferably, the part to be picked up is a thin metal sheet that matches the magnetic part on the bag-picking component.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figures 1-10 As shown, this utility model provides a bag, including a bag body, which includes a front bag face 1, a rear bag face 2, a left bag face 3, a right bag face 4, and a bottom face. The front bag face 1, left bag face 3, rear bag face 2, right bag face 4, and bottom face form an accommodating space with an upper opening. The left bag face 3 and right bag face 4 can be folded between the front bag face 1 and the rear bag face 2. The two sides of the rear bag face 2 extend outward with rear extension edges 5 that are not connected to the accommodating space. Each rear extension edge 5 is provided with a fixing hole 6 through which a bag-fixing protrusion can pass, so that the bag opening side and the bag bottom side of the bag body are positioned at multiple locations.

[0029] The bag of this invention has a rear extension edge 5 on the rear bag face 2, and a fixing hole 6 on the rear extension edge 5. The rear extension edge 5 is not connected to the containing space, and the fixing hole 6 is also not connected to the containing space of the bag. Therefore, there is no leakage problem when liquid garbage or garbage containing fine particles and dust is placed inside the bag, and it will not soil surrounding items or the environment. The left bag face 3 and right bag face 4 of this invention can be folded and positioned between the front bag face 1 and the rear bag face 2, allowing multiple bags to be stacked together. The bag of this invention can be directly or indirectly installed in a trash can through the fixing hole 6, achieving multi-part positioning of the bag opening and bottom sides. The front bag face 1 is not positioned, allowing it to be easily separated from the rear bag face 2, thus enabling the bag opening and bottom sides to be easily unfolded. It can be placed in a trash can and can be automatically unfolded in multiple parts.

[0030] Preferably, the front side of the bag has multiple pickup sections evenly distributed on both sides of the front side, so that the bag opening and bottom sides of the front side of the bag can be picked up from multiple parts. During the bag unfolding process, the pickup section on the bag-retrieving device in the trash can can pick up multiple pickup sections, allowing the bag opening and bottom sides of the front side of the bag to be picked up from multiple parts, thus separating the front and rear bag surfaces, enabling both the bag opening and bottom sides to be unfolded. The pickup section on the bag-retrieving device can be a magnetic part, and the pickup section is a thin metal sheet 7 that matches the magnetic part on the bag-retrieving device. By having the magnetic part on the bag-retrieving device approach the front side of the bag and attract the thin metal sheet 7 on the front side of the bag, the front bag surface 1 and the rear bag surface 2 are separated, thus unfolding the bag. Alternatively, the pickup section on the bag-retrieving device can be an adhesive part, which can adhere the pickup section on the front side of the bag, thus separating the front and rear bag surfaces, thus unfolding the bag. The picking part on the bag picker can also be a clamping part. The clamping part can clamp the part to be picked up on the front side of the bag body, and then separate the front bag surface from the back bag surface to unfold the bag.

[0031] Preferably, the front bag surface 1 has two outwardly extending front extension edges 8 that are opposite to the rear extension edges 5 and not connected to the receiving space. Each front extension edge 8 has a pickup part, and each front extension edge 8 also has a clearance area 9 that corresponds one-to-one with the fixing holes 6 and allows the bag-fixing protrusions to pass through. When the bag is folded, the front extension edges 8 and the rear extension edges 5 are opposite to each other, and the clearance area 9 is opposite to the fixing holes 6. In this way, the front extension edges 8 will not block the front of the fixing holes 6, making it convenient for the bags to be positioned through the fixing holes 6 when stacked together. Moreover, the fact that the front extension edges 8 are not connected to the receiving space means that the clearance area 9 is also not connected to the receiving space of the bag. There is no leakage problem when liquid garbage or fine particles and dust are put into the bag, and the surrounding items and environment will not be soiled.

[0032] Preferably, the clearance area 9 is a clearance hole with a diameter larger than the outer diameter of the bag-fixing protrusion; or, the clearance hole has a notch 10 on its edge; or, the clearance area is a clearance buttonhole with a diameter larger than the outer diameter of the bag-fixing protrusion when opened. When the clearance area 9 and the fixing hole 6 are positioned together on the bag-fixing protrusion, the rear bag surface 2 can be left on one side of the bag-fixing protrusion during bag unfolding, while the front bag surface 1 can easily detach from the bag-fixing protrusion, allowing for smooth bag unfolding.

[0033] Preferably, the fixing hole 6 has at least one easy-tear seam 11 on the edge of the hole, so that the back bag 2 can be easily removed from the fixing protrusion after use.

[0034] Preferably, the bag body is provided with a handle 12, which can be a drawstring or a lifting hole. After the bag is used, the entire bag can be lifted by the handle 12.

[0035] Preferably, each of the rear extension edges has one fixing hole, which is a vertically arranged elongated hole. The two ends of the elongated hole extend to the bag opening side and the bag bottom side of the bag body, respectively, so that the upper and lower ends of both sides of the bag body can be positioned on the bag fixing protrusion. Alternatively, each of the aforementioned rear extension edges has at least two fixing holes, which can be round or polygonal and evenly distributed between the bag opening side and the bag bottom side on the same side of the bag body, so that the upper and lower ends of both sides of the bag body can be positioned on the bag fixing protrusions.

[0036] like Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10As shown, this utility model also provides a stacked structure, including multiple bags, each of which is the bag described above. The multiple bags are stacked together, and the fixing holes 6 of the multiple bags are aligned one-to-one. The back bag surface 2 of the previous bag is aligned with the front bag surface 1 of the next bag. After being stacked, the multiple bags can be positioned together on the bag-fixing protrusions through the fixing holes 6. The structure is simple and easy to use.

[0037] like Figure 4 , Figure 5 , Figure 6 , Figure 9 , Figure 10 As shown, this utility model also provides a bag assembly, including a bag fixing component 13 and a bag. The bag adopts the aforementioned stacked structure. The bag fixing component 13 is provided with multiple bag fixing protrusions 14, which pass through the fixing holes 6 of the bag to position the bag on the bag fixing component 13. The front bag face 1 of the bag is located on the outer side. Multiple bags of this utility model can be stacked and installed on the bag fixing protrusions 14 of the bag fixing component 13, thus forming a bag assembly with the bag fixing component 13. Multiple bags can be detachably installed in a trash can through the bag fixing component 13, making operation convenient and quick. When there are two bag-fixing protrusions, they can be elongated and aligned with the elongated holes on both sides of the bag body, so that the upper and lower ends of both sides of the bag body can be positioned on the bag-fixing protrusions. When there are at least four bag-fixing protrusions 24, they can be cylindrical, prismatic, etc., and aligned with the fixing holes distributed between the upper and lower ends of both sides of the bag body, so that the upper and lower ends of both sides of the bag body can be positioned on the bag-fixing protrusions 24. Some or all of the bag-fixing protrusions 14 are provided with anti-detachment protrusions 15 at their outer ends, so that the bag fixing holes 6 cannot be freely detached after being fitted onto the bag-fixing protrusions 14. After the picking part on the bag picking component picks up the front side of the bag body, it ensures that the back side of the bag is left on the bag-fixing component 13.

[0038] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
