Description

Technical Field

[0001] This utility model relates to the field of bags, and more particularly to an integrated handle-binding paper bag. Background Technology

[0002] Most existing paper bags have a regular hexahedral structure with a handle only at the top and no internal positioning structure for cup-shaped containers. When a single or double cup of beverage is placed inside, the cup can easily tilt, wobble, or even tip over, causing spillage. Some solutions incorporate independent trays or dividers inside the bag, but these require additional components, increasing cost and space. Other solutions involve punching holes in the bag wall to create the cup opening, but this compromises the bag's integrity and reduces its load-bearing capacity. Therefore, achieving reliable cup positioning without affecting the folding of the paper bag or adding excessive material has become a pressing technical problem. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an integrated handle-binding paper bag.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] The one-piece handle-binding paper bag includes an adjacent front and side panels. The side panels have a vertically extending center crease that divides them into a first side and a second side. A side crease connects the front panel to the first side.

[0006] It also includes a restraint strap, which has a first fixing part and a second fixing part, as well as a cup-shaped part between them. The first fixing part is connected to the inner surface of the front of the bag body, and the second fixing part is connected to the inner surface of the side of the bag body. The connection here can be a fixed connection, a detachable connection, or a movable connection, as long as it ensures that the restraint strap is integrated with the bag body and will not detach from the bag body during normal use. The inner surface of the front of the bag body and the inner surface of the side of the bag body are broad concepts, referring to the front or side of the bag body or parts extending from the bag body.

[0007] The restraint strap is at least in an unfolded state. The cup support part forms a channel between the front and side of the bag body, allowing the cup to be inserted from top to bottom. The cup support part is used to wrap around one side of the cup body within the insertion channel. The inner surfaces of the front and side of the bag body are used to contact the other side of the cup body. The restraint strap, together with the front, side, and bottom of the bag body, forms a limiting support for the outer periphery of the cup body. Compared with traditional cup holders that rely on themselves to support the bottom of the bag body, the bag body of this utility model also participates in limiting the cup body from the bottom and side surfaces of the cup body. The restraint strap does not achieve cup body limiting on its own. This reduces costs, makes full use of materials, and reflects the concept of environmental protection.

[0008] The binding strap also has a folded-up state that fits snugly against the inner surface of the bag. The inner surface binding strap on the side of the bag has a first crease that overlaps with the side crease. When the bag is opened or folded, the binding strap remains snug against the front and sides of the bag. When unfolded, the cup support, together with the front and sides of the bag, forms a channel for inserting the cup. The cup support wraps around one side of the cup, and the bag wall contacts the other side. Utilizing the adjacent sides of the bag itself and a binding strap in conjunction, a three- or four-point arc-shaped restraint is formed, creating a lateral circumferential restraint on the outer periphery of the cup, keeping the cup upright during transportation. When folded, the binding strap fits against the bag wall and folds along with the creases of the bag, while the paper bag remains flat and folded. The binding strap can also increase friction with the cup by adding protrusions and increase the contact area with the cup surface by widening it, thereby enhancing the anti-tipping effect.

[0009] Preferably, the second fixing part is fixedly connected to the inner surface of the second side, so that the cup support part passes over the middle crease, and the binding strap has a second crease that overlaps with the middle crease when it is in the gathered state.

[0010] Preferably, the two ends of the cup support are equidistant from the side crease, so that the binding strap, together with the front and side of the bag, forms a limiting support with three isosceles triangles or four squares on the side of the cup. Since the optimal range is less than two cup diameters and greater than half the cup's circumference, the purpose is that when the cup is placed inside the bag, the cup support can be opened. If the binding strap is large, the first crease remains slightly folded, and the sides of the cup support form two arc-shaped bindings on the cup. If the binding strap is small, the second crease is opened by the cup, and the center of the cup support forms an arc-shaped binding on the cup.

[0011] Preferably, the binding strap is made of strip or sheet of paper, and the first fixing part and the second fixing part are respectively fixed to the front and side of the adjacent bag body by adhesive.

[0012] Preferably, the direction of the binding strap is parallel to the bottom plane of the paper bag.

[0013] Preferably, the first and second fixing parts at both ends of the binding strap are at the same height, with the side of the first and second fixing parts furthest from the side crease being higher than the side closest to the side crease. The binding strap is inclined with higher sides and lower middle, giving the cup support a tapered shape that tapers inward from top to bottom when the binding strap is unfolded. This design can accommodate the typical frustum shape of a cup, which is wider at the top and narrower at the bottom, allowing the cup support of the binding strap to fit more snugly against the cup surface, resulting in greater stability of the cup during use.

[0014] Preferably, the distance from the highest point of the restraint strap to the bottom of the bag increases as the height of the cup increases or the diameter of the cup decreases. The higher the cup's center of gravity, the higher the position of the restraint strap should be, typically at least one-third of the cup's height above the bottom, to provide more stable support. When the cup diameter is small, the center of gravity is high and the support surface is small, making it prone to tilting. In this case, the point of application of the restraint strap 2 needs to be raised as needed. For larger diameter cups, due to the larger bottom contact area and lower center of gravity, the point of application of the restraint strap 2 can be appropriately lowered.

[0015] Preferably, the distance S between the lowest point of the cup-supporting part of the restraint strap and the bottom of the bag body is not less than 0.2 times the length L of the cup-supporting part. When the cup diameter is too small and the point of action is too low, the cup body is prone to detach from the limiting area. Therefore, the restraint strap is above a certain height, and the restraint strap is located at or above the center of gravity of the cup to better support the cup body and ensure that the cup does not tip over. This makes the cup body more stable.

[0016] Preferably, the number of straps is one, and the paper bag is used to hold the single cup.

[0017] Preferably, there are two binding straps. The paper bag is used to hold the double cups, and the binding straps on both sides are symmetrically fixed to different sides of the bag. Since the cups are restrained by the binding straps on the outer front, sides, and inner sides of the bag, even if placing a single cup causes an imbalance in weight on both sides of the bag, the cup holder will not become unbalanced like a traditional built-in cup holder. Its position of action is higher than that of a traditional cup holder, and it still has a good restraining and anti-tipping effect on the cups.

[0018] Preferably, at least two binding straps are distributed vertically on the front and sides of the bag, corresponding to the same cup. This provides multiple layers of binding for the cup, resulting in better support.

[0019] This utility model, by adopting the above technical solution, has significant technical effects:

[0020] 1. The restraint straps form a lateral embrace with the adjacent bag walls to prevent swaying. The restraint straps can be positioned high, and their effective position is higher than that of traditional cup holders. This allows the point of contact between the cup support and the cup body to be higher than the cup's center of gravity, resulting in better anti-tipping performance and reliable cup body positioning.

[0021] 2. No additional parts are required. The restraint strap is glued on as a whole during the bag body processing. Users do not need to add a cup holder step. Simply stretch the restraint strap and put the cup in.

[0022] 3. The folding method remains unchanged, and the pre-set creases on the binding straps overlap with the original creases on the bag body, allowing the paper bag to still be flattened for transport. It is also thinner than traditional cup holders, making it easier to store.

[0023] 4. Wide range of applications: By setting a single restraint strap or symmetrical double restraint straps, it can be compatible with single-cup and double-cup scenarios.

[0024] 5. Made of paper strips or sheets, it is cheaper than traditional cup holders. The binding strap is easy to process; it only needs to be cut and glued to the upper surface of the bag blank before the bag body is processed into a tube. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] One-piece handle binding paper bag, such as Figure 1-2 As shown, the bag includes an adjacent front panel 11 and a side panel 12. The side panel 12 has a vertically extending center crease 121 that divides it into a first side panel 122 and a second side panel 123. A side crease 13 is located between the front panel 11 and the first side panel 122.

[0036] like Figure 4As shown, it also includes a restraint strap 2, which has a first fixing part 21, a second fixing part 22, and a cup-supporting part 23 between them. The first fixing part 21 is connected to the inner surface of the front side 11 of the bag body, and the second fixing part 22 is connected to the inner surface of the side side 12 of the bag body.

[0037] like Figure 1 and 3 As shown, the restraint strap 2 is at least in an unfolded state. The cup support 23 forms a channel 3 between the front 11 and the side 12 of the bag body, through which the cup body is inserted from top to bottom. The cup support 23 is used to wrap around one side of the cup body in the insertion channel. The inner surfaces of the front 11 and the side 12 of the bag body are respectively used to contact the other side of the cup body. The restraint strap 2, together with the front 11, the side 12, and the bottom surface of the bag body, forms a limiting support for the outer periphery of the cup body.

[0038] like Figure 2 and 7 As shown, the binding strap 2 also has a gathered state that adheres to the inner surface of the bag. The inner surface of the binding strap 2 on the side 12 of the bag has a first crease 24 that overlaps with the side crease 13. When the bag is opened or folded, the binding strap 2 remains attached to the front 11 and the side 12 of the bag. The binding strap 2 can be made of the same paper as the front 11 and the side 12 of the bag, or it can be made of thicker paper or other materials that are easy to stick.

[0039] like Figure 5-6 As shown, the second fixing part 22 is connected to the inner surface of the second side 123, so that the cup support part 23 passes over the middle crease 121. When the binding strap 2 is in the folded state, it has a second crease 25 that overlaps with the middle crease 121.

[0040] The two ends of the cup support 23 are equidistant from the side crease 13, so that the binding strap 2, together with the front 11 and the side 12 of the bag body, forms a limiting support for the side of the cup body with three arc surfaces distributed in an isosceles triangle or four arc surfaces distributed in a square.

[0041] The binding strap 2 is made of strip or sheet of paper, and the first fixing part 21 and the second fixing part 22 are respectively fixed to the adjacent front 11 and side 12 of the bag body by adhesive.

[0042] The extension direction of the binding strap 2 is parallel to the bottom plane of the paper bag.

[0043] In this embodiment, there are two binding straps 2. The paper bag is used to hold the double cups. The binding straps 2 on both sides are fixed to different sides of the bag in a centrally symmetrical manner.

[0044] like Figure 6-7As shown, before processing, the bag body has unfolded pieces with a front (11), sides (12), and bottom. A binding strap 2 is cut out and attached to the inner surface of the bag body. The cup-shaped portion 23 of the binding strap 2 crosses the center crease 121. The bag body is then shaped using traditional methods. When folding the bag body, the side 12 presses against the center crease 121, and a side crease 13 is pressed between the front (11) and the first side 122. The bag body is then folded along these creases, causing the binding strap 2 to form a first crease 24 and a second crease 25, coinciding with the bag body creases. The entire bag can then be flattened and folded.

[0045] When in use, open the bag and operate the cup support part 23 to leave the bag wall to form the channel 3; insert the cup body from top to bottom, the cup support part 23 surrounds the side wall of the cup body, and together with the front 11 and the side 12, it forms a three-point arc surface limit or a four-point arc surface limit to keep the cup body upright and not shake.

[0046] In this embodiment, a second binding strap 2 is symmetrically arranged on another set of adjacent sides of the bag, with the two straps being symmetrical. The two channels 3 can each accommodate a cup, the bag is balanced by force, and it remains stable when lifted.

[0047] The distance from the highest point of the restraint strap 2 to the bottom surface of the bag increases as the height of the cup increases or the diameter of the cup decreases.

[0048] Example 2

[0049] In another embodiment, the number of straps 2 is one, the paper bag is used to hold the single cup, and the rest of the structure is the same as in embodiment 1.

[0050] Example 3

[0051] In another embodiment, at least two binding straps 2 are distributed vertically and connected vertically to the front 11 and the side 12 of the bag body, corresponding to the same cup body. The number of cup bodies can be one, two, or more. The rest of the structure is the same as in embodiment 1.

[0052] Example 4

[0053] As another implementation, the rest of the structure is the same as in embodiment 1 or 2, except that the first fixing part 21 and the second fixing part 22 at both ends of the binding band 2 are at the same height, and the side of the first fixing part 21 and the second fixing part 22 away from the side crease 13 is higher than the side of the side crease 13. The binding band 2 is in an inclined state with high sides and low middle, so that the cup support part 23 has a tapered inward from top to bottom when the binding band 2 is unfolded.
