Technical Field

[0001] The utility model relates to the technical field of packaging bags, specifically a triangular packaging bag. Background Art

[0002] Traditional single-cup packaging bags for coffee and tea drinks are usually quadrilateral structures, that is, they have four bag surfaces. In order to ensure the stability of coffee and milk tea and reduce shaking during food delivery or when consumers take them out, a cup holder will be placed in the bag, but this increases the cost, and the cup holder will get stuck with the cup when the consumer uses it, making it inconvenient to take out. To solve the above problems, this case came into being. Content of the Utility Model

[0030] Embodiment 1

[0031] As Figures 1 - 6 shown, this embodiment provides a triangular packaging bag, which includes a basic bag body. A number of bottom creases for folding to form the bag bottom and a number of side creases for facilitating the folding of the bag body are provided on the basic bag body. Any one side edge of the basic bag body is set as the adhesive edge, and the two side edges are adhesively closed through the adhesive edge to form the bag body. The bag body has a total of 3 bag surfaces, and the formed packaging bag is in a triangular prism structure. The bag body and the bag bottom are combined to form a placing cavity, and the top end of the placing cavity is the bag opening.

[0032] Furthermore, the packaging bag is integrally provided with a lifting part.

[0033] Furthermore, after the basic bag body is folded along the bottom crease to form the bag bottom, it is fixed by adhesive paste.

[0034] Furthermore, the bottom crease divides three bag bottom surfaces at the bottom end part of the basic bag body, and the three bag bottom surfaces are overlapped and adhered to form the bag bottom.

[0035] Furthermore, the three bag bottom surfaces are respectively the first bag bottom surface, the second bag bottom surface, and the third bag bottom surface. The second bag bottom surface is folded and adhered to the first bag bottom surface, and the third bag bottom surface is folded and adhered to the second bag bottom surface.

[0036] Furthermore, the packaging bag is integrally provided with a protruding structure. A notch for facilitating the folding of the bag bottom surface is provided at the bottom end of the basic bag body, and the shape and size of the notch are adapted to the protruding structure.

[0037] Furthermore, the protruding structure is of any shape, the shape area of the protruding structure is less than or equal to the shape area of the notch, and the shape range of the notch includes the shape range of the protruding structure. Any shape means that this part can be set as a logo pattern to achieve an identification effect. Taking the triangular packaging bag as a paper bag as an example, referring to Figure 3 , Figure 3It is a paper sheet unfolding structure for forming a triangular packaging bag by single folding. The paper sheet is successively cut into corresponding basic shapes through a bag-making device from a roll of paper; for example, if paper sheet A and paper sheet B are adjacent, after the roll of paper is cut, the notch of paper sheet A forms a protruding structure of paper sheet B. The protruding structure is designed as an M shape or a pentagram shape.

[0038] Embodiment 2

[0039] As Figures 7 - 9 shown, this embodiment provides a triangular packaging bag. The difference between this embodiment and Embodiment 1 is that a lifting part is formed by opening a hole at the top of the basic bag body.

[0040] The lifting part structures in Embodiments 1 and 2 are integrated with the packaging bag. In Embodiment 2, the lifting part can be formed by opening a hole on the corresponding bag surface of the basic bag body, and the position of this hole is the position where the hand reaches in to lift the packaging bag.

[0041] As Figure 9 shown, the bag surface of the triangular packaging bag is divided into three bag surfaces C, D, and A + B. Surface A and surface B are axisymmetric about La, and surface C and surface D are axisymmetric about Lb; L1 = L2, L3 = L4, (L1 + L2) ≤ L3; 0° ≤ θ ≤ 90°, preferably 60° ≤ θ ≤ 75°, and further preferably, θ is selected as 45°.

[0042] Embodiment 3

[0043] As Figure 10 shown, this embodiment provides a triangular packaging bag. The difference between this embodiment and Embodiment 1 is that a lifting part is fixedly pasted at the top of the basic bag body. That is, in this embodiment, the lifting part is not formed by using the structure of the basic bag body itself, but an additional lifting part is pasted with a colloid. This lifting part structure can be a lifting rope, and fixing pieces are pasted at both ends of the lifting rope, and the fixing pieces are then fixed on the bag surface by means of colloid pasting. Traditional packaging bags usually have two external lifting parts (lifting handles), and the bag mouth of traditional packaging bags is usually quadrilateral, so two lifting handles are set; in this embodiment, it is preferably to set three lifting handles on the triangular packaging bag, that is, one is set on each bag surface.

[0044] Embodiment 4

[0045] This embodiment provides a triangular packaging bag. The difference between this embodiment and Embodiment 1 is that a strengthening structure is arranged around the lifting part, and an adhesive structure for sealing is arranged around the bag mouth position of the packaging bag, such as: an adhesive structure is arranged near the bag mouths of the second bag surface and the third bag surface.

[0046] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
