Description

Technical Field

[0001] The utility model relates to the technical field of paper containers, in particular to a cup sleeve and a portable paper cup. Background Art

[0002] Paper cups are favored by the catering industry because of their lightness, low cost and environmental protection. In order to facilitate carrying, some paper cups are also provided with handles or grips. The existing handles are usually paper ropes or paper tapes, which are directly bonded to the side walls of the paper cups. Since the paper ropes or paper tapes need to occupy a certain space, the stacking space of such portable paper cups is often large, and the cup walls are easily crushed during the stacking and transportation process. In addition, the existing assembly method through plastic outer bags also requires manual bagging, which is cumbersome and not only unfavorable to the environment but also reduces the packaging efficiency. Utility Model Content

[0003] Since existing portable paper cups take up a large space when stacked and the handles or grips are easily crushed by the cup walls, it is necessary to provide a cup sleeve and a portable paper cup.

[0004] A cup sleeve, comprising:

[0005] A sleeve body, wherein the side wall of the sleeve body is provided with at least one hollow groove; and

[0006] At least one belt body is located in the hollow groove, and two ends of the belt body are arranged at intervals along the circumference of the sleeve body and connected to the sleeve body.

[0007] With such arrangement, since the hollow groove provides accommodation space for the belt body, the entire cup sleeve is more compact when actually stacked, which is beneficial to reducing the stacking volume of the cup sleeves, and the belt body will not affect the stacking of the sleeve bodies of multiple cup sleeves due to its own existence.

[0008] In one embodiment, the shape of the hollow groove is the same as the shape of the belt body.

[0009] Such an arrangement is helpful to reduce the influence of the hollow groove on the structural strength of the sleeve.

[0010] In one of the embodiments, the cup sleeve has at least one pair of indentation lines arranged at intervals along the axial direction, and the indentation lines have a starting point and an end point located on one side of the circumferential wall of the cup sleeve close to the end and arranged at intervals along the circumferential direction, and the two indentation lines of each pair of the indentation lines are respectively bent and extended along their own starting points toward the end points to divide the cup sleeve into the sleeve body and the belt body.

[0011] In this way, the shape of the belt body and the sleeve body is depicted on the cup sleeve through the indentation line, and in actual use, only the belt body needs to be folded. The production and processing are convenient, and the overall structural strength of the cup sleeve is high. In addition, the formation method of the belt body determines that it will not affect the stacking of the sleeve body, and the belt bodies of two adjacent cup sleeves can also overlap each other, thereby improving the compactness of the cup sleeve stacking.

[0012] In one embodiment, the indentation line includes a first extension segment axially extending from the starting point toward the other end of the cup sleeve, a second extension segment axially extending from the end point toward the other end of the cup sleeve, and a third extension segment extending from the first extension segment to the second extension segment.

[0013] Such a configuration is conducive to extending the length of the belt body, thereby increasing the accommodation space formed by the belt body and the sleeve body after the belt body is folded, making it easier to insert fingers.

[0014] In one embodiment, chamfers are provided between the third extension section and the first extension section, and between the third extension section and the second extension section.

[0015] Such an arrangement is helpful to prevent the belt body from being torn at both ends of the third extension section.

[0016] In one embodiment, the sleeve body has a first opening end and a second opening end that are far away from each other, the starting point and the end point of the indentation line are located on a side of the sleeve body peripheral wall close to the first opening end, the third extension section is arc-shaped, and the third extension section gradually approaches the second opening end in a direction extending from both ends toward the middle.

[0017] Such an arrangement further prolongs the length of the extension section and enlarges the accommodation space formed by the belt body and the sleeve body after the belt body is folded.

[0018] In one embodiment, each pair of the indentation lines extends at equal intervals.

[0019] With such arrangement, a creasing knife with a fixed spacing can be used in the production process, which simplifies the structure and reduces the production cost.

[0020] In one embodiment, the number of the hollow grooves and the number of the belt bodies are both two and they are symmetrically arranged along the central axis of the sleeve.

[0021] With such arrangement, the sleeve body is subjected to balanced force and is not easy to shake, which is helpful to prevent the liquid in the paper cup from spilling out.

[0022] The present application also provides a portable paper cup, comprising:

[0023] a paper cup body having a rolled mouth; and

[0024] As in the cup sleeve described above, the cup sleeve is mounted on the paper cup body and the rolled edge abuts against the end of the cup sleeve.

[0025] With such arrangement, the paper cup body and the cup sleeve can be kept in close contact with each other under the action of gravity, and are stopped by the rolled mouth, so that the paper cup body and the cup sleeve are not easy to separate after being locked together.

[0026] In one embodiment, the sleeve of the cup sleeve is bonded to the paper cup body, and the portable paper cup has a first state and a second state;

[0027] When the portable paper cup is in the first state, the belt body is located in the hollow groove and abuts against the outer peripheral wall of the paper cup body; when the portable paper cup is in the second state, the belt body is located outside the hollow groove and abuts against the rolled mouth of the paper cup body.

[0028] With such arrangement, the sleeve and the paper cup body are bonded and fixed, and the structure is firm. In addition, the portable paper cup provides the user with the option of carrying it by hand, that is, the user is not forced to accept the portable paper cup, and different practical usage requirements are taken into consideration.

[0041] Paper cups are favored by the catering industry because of their lightness, low cost and environmental protection. In order to facilitate carrying, some paper cups are also provided with handles or grips. The existing handles are usually paper ropes or paper tapes, which are directly bonded to the side walls of the paper cups. Since the paper ropes or paper tapes need to occupy a certain space, the stacking space of such portable paper cups is often large, and the cup walls are easily crushed during the stacking and transportation process. In addition, the existing assembly method through plastic outer bags also requires manual bagging, which is cumbersome and not only unfavorable to the environment but also reduces the packaging efficiency.

[0042] Based on this, it is necessary to provide a cup sleeve and a portable paper cup that can achieve tight stacking during production and prevent the cup wall from being damaged.

[0043] See also Figure 1 , Figure 1 The structure diagram of a portable paper cup in one embodiment of the utility model is shown in the figure. The portable paper cup provided by the present application includes a paper cup body 20 and a cup sleeve 10. The paper cup body 20 has a rolled mouth 21. The cup sleeve 10 is sleeved on the paper cup body 20 and the end of the cup sleeve 10 abuts against the rolled mouth 21. Specifically, the cup sleeve 10 matches the shape of the paper cup body 20, that is, the cup sleeve 10 has a first open end 101 and a second open end 102 that are away from each other. The size of the first open end 101 is larger than the size of the second open end 102. The paper cup body 20 enters the cup sleeve 10 from the first open end 101, and the first open end 101 of the cup sleeve 10 abuts against the rolled mouth 21 of the paper cup body 20. In this way, the paper cup body 20 and the cup sleeve 10 can be kept tightly together under the action of gravity, and are stopped by the rolled mouth 21. After the paper cup body 20 and the cup sleeve 10 are locked together, they are not easy to separate.

[0044] Optionally, in an embodiment provided in the present application, the cup sleeve 10 is bonded to the paper cup body 20, so that the overall structure of the portable paper cup is more solid.

[0045] See also Figure 2 , Figure 2 for Figure 1 Schematic diagram of the structure of the middle cup sleeve 10. Optionally, in an embodiment provided in the present application, the cup sleeve 10 includes a sleeve body 11 and two belt bodies 12, the hollow grooves 111 and the belt bodies 12 are arranged in pairs, and the cup sleeve 10 has two pairs of symmetrically arranged hollow grooves 111 and belt bodies 12, and the two ends of the belt body 12 are arranged at intervals along the circumference of the sleeve body 11 and connected to the sleeve body 11. Since the hollow grooves 111 provide a space for the belt body 12 to accommodate, the entire cup sleeve 10 is more compact when actually stacked, which is conducive to reducing the stacking volume of the cup sleeve 10, and the belt body 12 will not affect the stacking of the sleeve bodies 11 of multiple cup sleeves 10 due to its own existence.

[0046] It is worth noting that the portable paper cup has two states: a first state and a second state. Figure 1 The structure shown is a schematic diagram of the portable paper cup in the second state. When the portable paper cup is in the first state, the belt body 12 is located in the hollow groove 111 and abuts against the outer peripheral wall of the paper cup body 20; when the portable paper cup is in the second state, the belt body 12 is located outside the hollow groove 111 and abuts against the rolled mouth 21 of the paper cup body 20. The portable paper cup provides users with a portable option, that is, it is not mandatory for users to accept the portable paper cup, taking into account different actual usage needs.

[0047] Preferably, in an embodiment provided in the present application, the cup sleeve 10 has a pair of indentation lines 13 arranged at intervals along the axial direction, and the indentation lines 13 have a starting point 1301 and an end point 1302 located on one side of the circumferential wall of the cup sleeve 10 near the end and arranged at intervals along the circumferential direction, and the two indentation lines 13 of each pair of indentation lines 13 are respectively bent and extended from their own starting point 1301 to the end point 1302 to divide the cup sleeve 10 into a sleeve body 11 and a belt body 12. In this way, the shapes of the belt body 12 and the sleeve body 11 are depicted on the cup sleeve 10 by the indentation lines 13, and in actual use, only the belt body 12 needs to be folded. The production and processing are convenient, and the overall structural strength of the cup sleeve 10 is high. In addition, the formation method of the belt body 12 determines that it will not affect the stacking of the sleeve body 11, and the belt bodies 12 of two adjacent cup sleeves 10 can also overlap each other, thereby improving the compactness of the stacking of the cup sleeve 10.

[0048] It is understandable that in other embodiments, the number of the indentation lines 13 can also be three or more to form multiple belt bodies 12. As long as the belt bodies 12 and the hollow grooves 111 are arranged correspondingly, the shape and position of the indentation lines 13 are not further limited in this application.

[0049] Furthermore, in an embodiment provided in the present application, the shape of the hollow groove 111 is the same as the shape of the belt body 12 , which helps to reduce the impact of the hollow groove 111 on the structural strength of the sleeve body 11 .

[0050] See also Figure 2 Specifically, in one embodiment provided in the present application, the indentation line 13 includes a first extension section 131 extending axially from a starting point 1301 toward the other end of the cup sleeve 10, a second extension section 132 extending axially from an end point 1302 toward the other end of the cup sleeve 10, and a third extension section 133 extending from the first extension section 131 to the second extension section 132. This is conducive to extending the length of the belt body 12, thereby increasing the accommodation space formed by the belt body 12 and the sleeve body 11 after being folded, and facilitating the insertion of fingers.

[0051] Furthermore, in an embodiment provided in the present application, chamfers 1331 are provided between the third extension section 133 and the first extension section 131 and between the third extension section 133 and the second extension section 132 , which helps to prevent the belt body 12 from being torn at both ends of the third extension section 133 .

[0052] Optionally, in an embodiment provided in the present application, the starting point 1301 and the end point 1302 of the indentation line 13 are located on one side of the peripheral wall of the sleeve 11 close to the first opening end 101, the third extension section 133 is arc-shaped, and the third extension section 133 gradually approaches the second opening end 102 in the direction extending from both ends toward the middle, thereby further extending the length of the extension section and expanding the accommodation space formed by the belt body 12 and the sleeve body 11 after being folded.

[0053] Optionally, in an embodiment provided in the present application, each pair of creasing lines 13 extends at equal intervals. During the production process, a creasing knife with a fixed interval can be used, which simplifies the structure and reduces the production cost.

[0054] See also Figure 3 and Figure 4 , Figure 3 for Figure 2 The front view of the cup sleeve 10 is shown. Figure 4 for Figure 3 The cross-sectional view of the cup sleeve 10 taken along the AA direction is shown. Optionally, in an embodiment provided in the present application, the length of the first extension section 131 and the second extension section 132 used to form the belt body 12 is greater than the opening radius of the first opening end 101 of the sleeve body 11. In this way, the two belt bodies 12 can be cross-connected and locked, thereby maintaining the stability of the center of gravity of the entire portable cup sleeve 10 during use and preventing the liquid in the paper cup body 20 from spilling.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
