[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0031] According to an embodiment of the utility model, a contactless straight straw connected packaging bag comprises a packaging bag body 1, in which a straight straw 2 is sealed and packaged, wherein at least one end of the straight straw 2 has a pointed tip 3, and a packaging film 4 matching the pointed tip 3 is provided on the packaging bag body 1, and the straight straw 2 can be separated from the packaging bag body 1 by piercing the packaging film 4.

[0032] Embodiment 1, as Figure 1 , Figure 2As shown, the packaging bag body 1 includes a packaging bag film 1a (sealing edge 1b formed by hot-melting three sides), and the packaging bag film 1a is formed by folding a packaging film 4 that matches the pointed tip 3. In addition, the sealing edge 1b of the three-side sealing is in a concave shape; at least one end of the straight straw 2 in the packaging bag body 1 has a pointed tip 3, and the pointed tip 3 of the straight straw 2 and the packaging film 4 are arranged at the same end.

[0033] like Figure 3 As shown, when the packaging bag body 1 adopts a back-sealing structure, packaging films 4 with folded edge structures that match the straight straw 2 are provided at both ends of the packaging bag body 1. The packaging film 4 is folded so that the pointed head 3 and the folded edge packaging film 4 are adjacently distributed, and the pointed head 3 of the straight straw 2 can effectively pierce the packaging film 4. In addition, when the packaging bag body 1 is a tube film with a hollow tube structure, after the straight straw 2 is placed, it is only necessary to seal the upper and lower edges of the tube film to complete the sealed packaging of the packaging bag body 1. The pointed head 3 of the straight straw 2 is located at either end of the left or right ends.

[0034] Embodiment 2, as Figure 4-Figure 7 As shown, the packaging bag body 1 includes a first packaging film 1-1 and a second packaging film 1-2; a packaging film 4 with a groove structure is integrally formed on the surface of the first packaging film 1-1, the second packaging film 1-2 is sealed and covers the surface of the first packaging film 1-1, a straight straw 2 is inserted into the groove, and the edges of the first packaging film 1-1 and the second packaging film 1-2 are hot-melt fused and connected.

[0035] Specifically, the packaging film 4 adopts a blister structure, which is conducive to using existing equipment to directly load the straight straw 2 into the groove of the blister structure, and then seal and connect the first packaging film 1-1 and the second packaging film 1-2. In addition, there is no obstruction of the sealing edge structure, which is conducive to the sharp end 3 of the straight straw 2 to pierce the packaging film 4.

[0036] Embodiment 3, as Figure 8 , Fig. 9 As shown, the utility model also discloses a packaging box body 5 used in conjunction with a contactless straight straw connected packaging bag, the packaging box body 5 comprises a box body 5a, a cover film 5b is sealed on the box body 5a, and the box body is connected by hot-melt fusion to form a sealed packaging box body.

[0037] Specifically, the thickness of the cover film 5b on the box body 5a is greater than the thickness of the packaging film 4. After the straight straw 2 pierces the packaging film 4 and the cover film 5b, the straight straw 2 enters the box body 5a, completing the insertion and connection of the straight straw 2. At the same time, since the thickness, material density, and friction of the cover film 5b are greater than the thickness, material density, and friction of the material itself of the packaging film 4, the friction of the cover film 5b on the straight straw 2 is greater than the friction of the packaging film 4 on the straight straw 2. In this way, after the straight straw 2 is pierced, the packaging bag body 1 can be removed smoothly, and the cover film 5b can be used to limit the sliding of the straight straw 2 and keep it inside the box body 5a. During the connection process, the hardness of the tip 3 of the straight straw 2 needs to meet the hardness of piercing the packaging film 4 and the cover film 5b at the same time.

[0038] When in use, pinch the upper half of the outer surface of the packaging bag body 1 with your hand, and insert the packaging bag body 1 equipped with the straight straw 2 into the box body 5a with the cover film 5b. During the insertion process, when the pointed head 3 of the straight straw 2 in the packaging bag body 1 contacts the cover film 5b of the box body 5a, the pointed head 3 can pierce the packaging film 4 and the cover film 5b, and the straight straw 2 penetrates into the box body 5a. In the process of the straight straw 2 penetrating the box body 5a, the packaging bag body 1 is compressed and deformed after being squeezed on the surface of the cover film 5b, so that the cover film 5b does not enter the box body 5a. When the straight straw 2 penetrates the bottom of the box body 5a, the penetration of the straight straw 2 is completed, and then the compressed and deformed packaging bag body 1 is pulled up until the packaging bag body 1 is separated from the straight straw 2, and the connection between the straight straw 2 and the box body 5a is completed.

[0039] In order to prevent the packaging bag body 1 and the straight straw 2 from being pierced into the box body 5a when the packaging bag body 1 pierces the cover film 5b, the width of the packaging bag body 1 needs to be set or widened according to a certain ratio according to the diameter of the straight straw 2. The widened packaging bag body 1 has a larger contact area and resistance during the insertion of the straight straw 2 into the cover film 5b, which can prevent the packaging bag body 1 from being dragged into the box body 5a when the straight straw 2 is inserted into the cover film 5b. When the ratio of the diameter of the straight straw 2 to the width of the packaging bag body 1 is greater than / equal to 1:3, it can effectively prevent the packaging bag body 1 from being dragged into the box body 5a. For example, the diameter of the straight straw is 5mm, and the width of the packaging bag body is 15mm or 20mm.

[0040] like Fig. 9 As shown, when the straight straw 2 is inserted into the cover film 5b, when the packaging bag body 1 is removed, in order to prevent the straight straw 2 from being taken out of the box body 5a, it is necessary to ensure that the friction between the cover film 5b and the connected straight straw 2 is greater than the friction between the packaging bag body 1 and the straight straw 2. This can effectively prevent the straight straw 2 from being taken out when the packaging bag body 1 is removed. Usually, this effect can be achieved by making the thickness of the cover film 5b greater than the thickness of the packaging bag body 1 by a certain multiple.

[0041] like Figure 8 , Fig. 9 and Fig.10 As shown, when the packaging bag body 1 and the cover film 5b are made of the same material, the thickness of the cover film 5b is 4 times or more than the thickness of the packaging bag body 1. When the straight straw 2 pierces the packaging film 4 and the cover film 5b to connect, the friction force of the cover film 5b on the straight straw 2 is much greater than the friction force of the packaging bag body 1 on the straight straw 2. In this way, when the packaging bag body 1 is pulled upward, the straight straw 2 is limited by the cover film 5b and will not move upward. The packaging bag body 1 is subjected to the upward pulling force and slides along the surface of the straight straw 2 until the packaging bag body 1 and the straight straw 2 are separated.

[0042] like Figure 8 , Fig. 9 and Fig.10 As shown, when the packaging bag body 1 and the cover film 5b are made of different materials, for example, the cover film 5b is a composite film, and also contains an aluminum-plated layer or an aluminum foil layer composite film. At this time, the outer surface, middle layer or inner surface of the cover film 5b has a plastic film of the same material as the packaging bag body 1, and the thickness of the plastic film of the outer surface, middle layer or inner surface of the corresponding cover film 5b is greater than or equal to the thickness of the packaging bag body 1. In this way, it can be ensured that during the insertion of the straight straw 2 into the cover film 5b, firstly, the packaging bag body 1 is prevented from being brought into the box body 5a together with the straight straw 2. Secondly, the plastic film of the same material or thickness can ensure that during the insertion of the straight straw 2 into the cover film 5b, the pointed tip 3 of the straight straw 2 punctures the packaging film 4 on the packaging bag body 1. Among them, the plastic film of the outer surface, middle layer or inner surface of the packaging bag body 1 and the cover film 5b is a single-layer plastic film, or it can be a composite film material.

[0043] Embodiment 4, as Fig.11 As shown, when one end of the straight straw 2 in the packaging bag body 1 is a curved straw 6, and the other end is a straight straw with a pointed tip 3; at the same time, the packaging bag body 1 is bonded to the box body 5a as a whole; the sealing edge of the packaging bag body 1 equipped with the curved straw is provided with a row of continuous easy-tear openings 8; the packaging bag body 1 is fixed to the packaging box body 5 through the first bonding end 9 at the top and the second bonding end 10 at the bottom. In addition, the first bonding end 9 is located at the position of the easy-tear opening 8, and is located in the upper middle part of the packaging bag body 1.

[0044] Fig.12 As shown, specifically, the first adhesive end 9 is kept at a distance of 2-5 cm from one end of the top of the packaging bag body 1. The second adhesive end 10 is located at the end of the other end of the packaging bag body 1. When in use, the packaging bag body 1 is torn open along the easy-tear edge 8 by the first adhesive end 9 from the top of the packaging bag body 1. After the entire packaging bag body 1 is torn open, the packaging bag body 1 is divided into two parts. The upper part of the packaging bag body 1 is pinched by the hand, and the curved straw 6 is taken out from the other part fixed at the bottom of the packaging bag body 1 ( Fig.12). Then insert the other end of the curved straw with the pointed tip 7 into the box body 5a, remove the upper half of the bag body 1 pinched by the hand, and complete the connection between the curved straw and the box body 5a.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
