3D bags

Abstract

This invention discloses a three-dimensional bag, comprising a bag body with a cavity and a handle at the opening of the bag body. A handle perforation is formed on the side wall of the bag body near the opening, corresponding to the end of the handle. The end of the handle extends from one side of the side wall of the bag body through the handle perforation to the other side and connects to the other side surface of the side wall of the bag body. Furthermore, in the height direction of the bag body, a connection area is formed between the handle perforation and the upper edge of the side wall of the bag body. The connection area has a predetermined height in the height direction, and the ratio of the predetermined height to the height of the bag body is in the range of 1:6 to 1:12. On the one hand, by moving the connection part between the handle and the bag body downward from the easily worn edge of the bag opening, the connection stability between the handle and the bag body is improved, ensuring the normal use of the three-dimensional bag and the safe loading of goods. On the other hand, the connection area can be used to install accessories for closing the bag opening, head clips to strengthen the edge of the bag opening, or decorative parts.

12.

2. The three-dimensional bag according to claim 1, wherein, The three-dimensional bag also includes a bag opening connector, which is disposed in the connection area.

3. The three-dimensional bag according to claim 2, wherein, The bag opening connector is a buckle that is disposed in the connection area of ​​the side wall on opposite sides of the bag body and corresponds to each other.

4. The three-dimensional bag according to claim 1, wherein, It also includes an end cap disposed at the top of one side wall of the bag body, the end cap extending toward the other side of the bag body to close the bag opening; one end of the end cap is connected to the top of the one side wall, and the other end forms an adhesive portion that can be connected to the connection area of ​​the other side wall; the end cap can be bent toward the connection area of ​​the other side wall, and the adhesive portion is bonded to the outer wall surface of the other side wall to close the bag opening of the bag body.

5. The three-dimensional bag according to claim 4, wherein, When the bag opening is closed, one sidewall of the bag body is attached to the other sidewall, the end cap is bent toward the other sidewall, and the adhesive part is bonded to the outer wall surface of the other sidewall; or, when the bag opening is closed, one sidewall of the bag body is spaced apart from the other sidewall, the end cap is bent toward the other sidewall, and the adhesive part is bent and attached to the outer wall surface of the other sidewall.

6. The three-dimensional bag according to claim 5, wherein, The adhesive part is set as Velcro or double-sided tape, and the end cap and the bag body are made of paper material or non-woven material; the end cap is integrally formed with the side wall; or, the end cap and the opposite ends of the side wall are overlapped and fixedly connected to each other.

7. The three-dimensional bag according to any one of claims 1 to 6, wherein, The predetermined height of the connection area in the vertical direction is in the range of 15 mm to 50 mm.

8. The three-dimensional bag according to any one of claims 1 to 6, wherein, The handle perforations are symmetrically arranged on a pair of front faces of the bag body; each handle perforation includes a linearly extending main cut, the main cut including a first extension and two second extensions extending from both sides of the first extension and communicating with the first extension, the two second extensions extending linearly with the first extension and smoothly transitioning at the connection points; and, the extension direction of the first extension is parallel to the upper edge of the bag opening, each second extension is inclined relative to the extension direction of the first extension, and the two second extensions extend in directions opposite to each other.

9. The three-dimensional bag according to claim 8, wherein, The two second extensions each have linearly extending auxiliary cuts formed at their opposite ends. Each auxiliary cut extends from the end of the corresponding side in a direction that bends and intersects with the extension direction of the corresponding second extension at that end, and the two auxiliary cuts extend in opposite directions.

10. The three-dimensional bag according to claim 8, wherein, The three-dimensional bag also includes handle reinforcements disposed on a pair of front surfaces for securing the end portions of the handles, the handle reinforcements penetrating the sidewalls of the front surfaces and the ends of the handles.
