Description

Technical Field

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

[0002] A cup sleeve is an accessory specially designed to be put on the outside of a cup. Its main function is to insulate, protecting the user's hands from being scalded by hot drinks. It can also prevent external factors from affecting the temperature of the drink, allowing hot drinks to stay warmer for longer and cold drinks to stay cooler for longer. It is usually used in milk tea shops, coffee shops and household glass cups.

[0003] Especially for milk tea shops and coffee shops, the cups used for milk tea and coffee are usually made of paper or plastic materials. When milk tea and coffee are hot drinks, due to the poor heat insulation of milk tea cups or coffee cups, if people touch them directly, the risk of being scalded is high. At present, the common means in the market is that milk tea shops and coffee shops will provide handbags for users to use. However, putting milk tea cups or coffee cups in handbags will make it difficult to place the milk tea cups or coffee cups. That is, when the milk tea cups or coffee cups are placed, the bottom of the handbag will affect the flatness of the bottom of the cup and the table or countertop foundation; on the other hand, the top of the handbag is often higher than the mouth of the cup, affecting the user's drinking. Therefore, there are many inconveniences in using handbags to insulate milk tea cups or coffee cups.

[0004] In this regard, in order to solve the above problems, the prior art has proposed a cup sleeve design that is mounted on the cup body. For example, a common cup sleeve design on the market is a cardboard tube mounted on the outside of the cup body. This design is equivalent to adding another layer of insulation to the outside of the cup body, which can only play a role in preventing scalding and its function is relatively simple. There is also a patent document with publication number TWM547909U that discloses a cup sleeve, in which a tear line is provided on a cylindrical cup body, and two straps can be torn off by pulling the tear line to be used as a handle; for this cup sleeve, if the stability of the cup sleeve is to be ensured, a thicker material needs to be used to make the cup sleeve, which will inevitably lead to a higher cost of the cup sleeve; if the cup sleeve is made of a thinner material to achieve the effect of reducing costs, since it is necessary to provide a tear line on the cup sleeve, when the handle is pulled up, the cup sleeve will have a hollow structure, which greatly affects the structural stability of the cup sleeve; and when making this cup sleeve, since its structural size is often small, the tear line on the cup body requires multiple actions to complete. If mechanical processing is used, the structure of its production equipment will be more complicated and the production cost will also be higher.

[0005] Therefore, the cup sleeve in the prior art has the problem of not being able to simultaneously achieve low cost and high structural stability. Utility Model Content

[0006] The purpose of the utility model is to solve the above problems in the prior art. The utility model provides a new cup sleeve, which can take into account both low cost and high structural stability. Specifically,

[0007] This cup sleeve includes a cylinder and a handle arranged on the cylinder. The cylinder has a side wall, a guide opening located at the top of the side wall, and a limiting opening located at the bottom of the side wall. The guide opening can be used to guide the cup sleeve to be sleeved on the outer wall surface of the cup body. By making the diameter of the guide opening larger than the diameter of the limiting opening, the guide opening can pass through the bottom of the cup body and allow the cup sleeve to be sleeved on the outer wall surface of the cup body. For a conical cup body, when the cup sleeve can be gradually sleeved from the bottom of the cup body to the cup opening using the guide opening, the limiting opening will gradually approach the outer wall surface of the cup body until it is tightly embraced by the outer wall surface of the cup body, thereby achieving relative fixation of the cup sleeve and the cup body.

[0008] Furthermore, the side wall of the cup sleeve smoothly extends from the limit opening to the guide opening in the height direction of the cylinder, and when the cup sleeve is completely sleeved on the outer wall of the cup body, the side wall of the cup sleeve can be completely fitted with the outer wall of the cup body, so that when the cup body is lifted by the cup sleeve, the gravity of the cup body will be evenly distributed to various parts of the side wall of the cup sleeve, avoiding excessive stress concentration on a certain part of the side wall of the cup sleeve, which may cause damage to the cup sleeve. Therefore, this design will make the structure of the cup sleeve more stable.

[0009] Furthermore, since the side wall is formed with a sealing part extending in the height direction of the cylinder, the stress direction applied by the cup body to the cup sleeve is not in the same direction as the sealing direction of the side wall of the cup sleeve. When the cup body is lifted, only a small part of the stress applied by the cup body to the cup sleeve will act on the sealing part. Therefore, this design will also reduce the stress value of the sealing part, thereby avoiding the existence of a vulnerable area on the cylinder, which is conducive to further improving the structural stability of the cup sleeve.

[0010] Furthermore, the cup sleeve provided by the utility model is also provided with a handle, so the cup sleeve and the cup body can be lifted by holding the handle, which is more convenient, and the two ends of the handle are respectively fixed to the end of one side of the side wall close to the guide port, at positions opposite to each other, and the two ends of the handle are arranged radially symmetrically with respect to the guide port, so that the force on the two ends of the handle is more uniform, and the handle and the cylinder body will not affect each other, that is, when the handle is pulled up or put down, the side wall of the cylinder body will not be affected.

[0011] Therefore, the cup sleeve designed with the above structure will have better structural stability when in use, the side wall of the cylinder does not require thicker materials, and does not require complicated processes and manufacturing equipment for production, thereby improving the structural stability of the cup sleeve while taking into account lower costs.

[0025] How to solve the problem of cup sleeves with both low cost and high structural stability is an urgent problem to be solved in the field of container technology. Especially with the continuous development of society, milk tea and coffee are becoming more and more popular among consumers, and various brands of milk tea shops and coffee shops have appeared on the market. In order to enhance the consumer experience, various milk tea shops and coffee shops will use a variety of cups for consumers to use.

[0026] Currently, the common milk tea cups or coffee cups on the market include cylindrical cups, conical cups and other types of cups. The body of the cylindrical cup is roughly cylindrical, with a slightly tilted top and a slightly narrowed bottom; the body of the conical cup is similar to a cone, with a wider bottom and a narrower top. It can be seen that the above two types of cups are basically large at the top and small at the bottom.

[0027] Furthermore, in the selection of milk tea cups or coffee cups, various milk tea shops and coffee shops usually use disposable cups, such as paper cups or plastic cups, in order to meet the convenience needs of consumers, diversify flavor choices, and consider cost factors. However, paper cups or plastic cups have relatively poor heat insulation during use, and are easy to burn hands for hot drinks, and are easy to deform at high temperatures, which will bring inconvenience to consumers.

[0028] In response to this, some milk tea shops or coffee cups are gradually considering adding a heat-insulating sleeve to the milk tea cup or coffee cup or providing a handbag to solve this problem. However, the existing heat-insulating sleeve is usually a hard paper tube, which can only play a role of heat insulation and has a relatively single function; although the handbag is more convenient to carry, it will affect the placement of the milk tea cup or coffee cup and the drinking of consumers.

[0029] It can be seen that it is extremely important to provide a cup sleeve that can take into account both heat insulation and portability. In the prior art, some solutions (such as the patent document with publication number TWM547909U) disclose a cup sleeve, which can solve the problem of taking into account both heat insulation and portability, but its production cost is high, and the structural stability of the cup sleeve is poor during use.

[0030] Furthermore, the utility model provides a new cup sleeve, which can reduce the manufacturing cost of the cup sleeve and improve the structural stability of the cup sleeve during use while taking into account heat insulation and portability.

[0031] The cup sleeve provided by the utility model is described in detail below:

[0032] See also Figures 1 to 3 The cup sleeve provided by the utility model includes a cylinder 100 and a handle 200 arranged on the cylinder 100, which is equivalent to the handle 200 being additionally fixed on the cylinder 100. In this way, during the manufacturing process of the cup sleeve, there is no need to perform other operations on the cylinder 100, and there is no need to set the cylinder 100 thicker in order to consider the setting of the handle 200.

[0033] Furthermore, the cylinder 100 has a side wall 110, a guide opening 120 located at the top of the side wall 110, and a limiting opening 130 located at the bottom of the side wall 110. The guide opening 120 can be used to guide the cup sleeve to be sleeved on the outer wall surface of the cup body. By making the diameter of the guide opening 120 larger than the diameter of the limiting opening 130, the guide opening 120 can pass through the bottom of the cup body and allow the cup sleeve to be sleeved on the outer wall surface of the cup body. For a conical cup body, when the cup sleeve can be gradually sleeved from the bottom of the cup body to the cup opening using the guide opening 120, the limiting opening 130 will gradually approach the outer wall surface of the cup body until it is tightly embraced on the outer wall surface of the cup body, thereby achieving relative fixation of the cup sleeve and the cup body.

[0034] The shape of the cylinder 100 is not limited, for example, it can be a cone, a pyramid, etc.

[0035] Taking a cone as an example, the side wall 110 of the cylinder 100 can be formed by winding a piece of substrate, and the two sides of the substrate are joined to form a sealing portion 111, and the cylinder 100 as a whole is a hollow truncated cone, and the cross section is a trapezoidal profile. In the manufacturing process, the substrate can be realized by a simple cutting action, and no complicated process actions and manufacturing equipment are required. The production cost of this cup sleeve can be further reduced.

[0036] The specific sizes of the calibers of the guide opening 120 and the limiting opening 130 are not limited. In one embodiment, the guide opening 120 and the limiting opening 130 are both circular openings, the inner diameter of the limiting opening 130 is in the range of 4 cm to 8 cm, and the inner diameter of the guide opening 120 is 1.2 to 1.6 times the inner diameter of the limiting opening 130. This structure of the cup sleeve is not only more coordinated in structure and more aesthetically pleasing, but also applicable to milk tea cups or coffee cups of various specifications on the market, and has a wider range of applications.

[0037] It should be understood that the inner diameter of the limit opening 130 can be any size in the range of 4 cm to 8 cm. Of course, for cups of some special sizes, the inner diameter of the limit opening 130 can also be set to other sizes. Correspondingly, the inner diameter of the guide opening 120 can be set to be in the range of 1.2 to 1.6 times the inner diameter of the limit opening 130. It is specifically determined according to the size of the cup body, and the present invention does not make a sole requirement.

[0038] Furthermore, during the design, the height dimension of the cylinder 100 can be designed to be 1.4 to 2.5 times the inner diameter dimension of the limit opening 130. On the one hand, it can effectively increase the area of ​​the cylinder holding the cup body, thereby making it easier for people to take the cup body and avoiding scalding the hands of the person taking the cup due to hot milk tea in the cup; on the other hand, it is conducive to improving the aesthetics of the cup body.

[0039] It should be understood that there is no specific requirement for the specific height dimension of the cylinder 100 , and it can be set within the range of 1.4 to 2.5 times the inner diameter dimension of the limiting opening 130 .

[0040] Furthermore, after the cup sleeve is formed, the side wall 110 smoothly extends from the limit opening 130 to the guide opening 120 in the height direction of the cylinder 100. When the cup sleeve is completely sleeved on the outer wall of the cup body, the side wall 110 of the cup sleeve can be completely fitted with the outer wall of the cup body. In this way, when the cup body is lifted by the cup sleeve, the gravity of the cup body will be evenly distributed to various parts of the cup sleeve side wall 110, avoiding excessive stress concentration on a certain part of the cup sleeve side wall 110, which may cause damage to the cup sleeve. Therefore, this design will make the structure of the cup sleeve more stable.

[0041] Furthermore, a sealing portion 111 extending along the height direction of the cylinder 100 is formed on the side wall 110, so that the stress direction applied by the cup body to the cup sleeve is not in the same direction as the sealing direction of the cup sleeve side wall 110. When the cup body is lifted, only a small part of the stress applied by the cup body to the cup sleeve will act on the sealing portion 111. Therefore, this design can also reduce the force value of the sealing portion 111, thereby avoiding the existence of a fragile area on the cylinder 100, which is conducive to further improving the structural stability of the cup sleeve.

[0042] Furthermore, the cup sleeve provided by the utility model is also provided with a handle 200, so when in use, the cup sleeve and the cup body can be lifted by holding the handle 200, which is more convenient, and the two ends of the handle 200 are respectively fixed to the end of one side of the side wall 110 close to the guide port 120, at positions opposite to each other, and the two ends of the handle 200 are arranged radially symmetrically relative to the guide port 120, so that the force on the two ends of the handle 200 can be more uniform, and the handle 200 and the cylinder 100 will not affect each other, that is, when the handle 200 is pulled up or put down, the side wall 110 of the cylinder will not be affected.

[0043] Therefore, the cup sleeve with the above structural design will have better structural stability when in use, the cylinder side wall 110 does not require thicker materials, and does not require complicated processes and manufacturing equipment for production, thereby improving the structural stability of the cup sleeve while taking into account lower costs.

[0044] Based on the above structure, during the cup sleeve forming process, the base material is wound and connected through the sealing portion 111 to form the cylinder 100 .

[0045] In one embodiment, see Figures 3 to 9 , the two side edges of the substrate may overlap up and down in the thickness direction of the side wall 110 and be fixedly connected to each other to form a sealing portion 111.

[0046] Regarding the position of the outer seam of the sealing portion 111:

[0047] like Figure 4 As shown, when the two side edges of the substrate overlap up and down in the thickness direction of the side wall 110 , the outer seam of the two side edges of the substrate may be located on the left side of the cup sleeve side wall 110 .

[0048] like Figure 5 As shown, when the two side edges of the substrate overlap up and down in the thickness direction of the side wall 110 , the outer seam of the two side edges of the substrate may be located on the right side of the cup sleeve side wall 110 .

[0049] The above two solutions only require overlapping and fixing the two side edges of the substrate, which makes the manufacturing process simpler and reduces the cost.

[0050] In another embodiment, see Figures 6 to 9 In the illustrated embodiment, two side edges of the substrate overlap and are fixedly connected to each other to form a sealing bending portion 112 , and the sealing bending portion 112 is joined to the wall surface of any adjacent side wall 110 of the two side edges to form a sealing portion 111 .

[0051] It should be understood that the sealing and bending portion 112 is formed by bending toward one side after two side edges of the substrate are butted, overlapped, and fixed to each other.

[0052] Regarding the bending direction of the sealing bending portion 112:

[0053] like Figure 6 and Figure 7 As shown, the sealing and bending portion 112 is bent toward the inside of the cylinder 100 , and the sealing and bending portion 112 is joined to the inner wall surface of any adjacent side wall 110 of the two side edges to form a sealing portion 111 .

[0054] like Figure 6 As shown, the sealing bending portion 112 is engaged with the inner wall surface of the right side wall 110 among the two side edges. For example, the two side edges of the substrate are bonded to each other and then bent toward the right side wall 110 among the two side edges inside the cylinder 100 and bonded to the inner wall surface of the right side wall 110.

[0055] like Figure 7 As shown, the sealing bending portion 112 is engaged with the inner wall surface of the left side wall 110 among the two side edges. For example, after the two side edges of the substrate are bonded to each other, they are bent toward the left side wall 110 among the two side edges of the cylinder 100 and bonded to the inner wall surface of the left side wall 110.

[0056] In the above two solutions, by bending the sealing bending portion 112 toward the inside of the cylinder 100, the seam at the outer wall 110 of the cylinder 100 can be made smooth and aesthetically pleasing.

[0057] like Figure 8 and Fig. 9As shown, the sealing bending portion 112 is bent toward the outside of the cylinder 100 and is joined to the outer wall surface of any adjacent side wall 110 of the two side edges to form a sealing portion 111 .

[0058] like Figure 8 As shown, the sealing bending portion 112 is joined to the outer wall surface of the right side wall 110 among the two side edges. For example, after the two side edges of the substrate are bonded to each other, they are bent toward the outside of the cylinder 100 toward the right side wall 110 among the two side edges and bonded to the outer wall surface of the right side wall 110.

[0059] like Figure 7 As shown, the sealing bending portion 112 is engaged with the inner wall surface of the left side wall 110 among the two side edges. For example, after the two side edges of the substrate are bonded to each other, they are bent toward the outside of the cylinder 100 toward the left side wall 110 among the two side edges, and bonded to the outer wall surface of the left side wall 110.

[0060] In the above two solutions, by bending the sealing bending portion 112 toward the outside of the cylinder 100, the seam at the inner wall 110 of the cylinder 100 can be made smooth, so that when the cup sleeve is put on the cup body, the inner wall surface of the cup sleeve can be completely fitted with the outer wall surface of the cup body, and the stability is better.

[0061] The size of the sealing portion 111 is not limited. For example, two side edges of the substrate with a width of 1.5 mm to 5 mm overlap each other to form the sealing portion 111, so that the width of the sealing portion 111 is within the range of 1.5 mm to 5 mm. Specifically, it can be any size within the range of 1.5 mm to 5 mm, such as 1.5 mm, 2.0 mm, etc.

[0062] Regarding the structural setting of the handle 200:

[0063] The structure and setting method of the handle 200 are not limited. For example, the handle 200 can be a flat belt, a cylindrical rope, or a rope with a triangular cross-section. The two ends of the handle 200 can be fixed to the inner wall of the cylinder 100, or fixed to the outer wall of the cylinder 100.

[0064] In one embodiment, see Figure 1 , Figure 2 , Fig.10The handle 200 is in the shape of a rope, and both ends of the handle 200 respectively have an extension section 210 extending to the lower side of the guide opening 120 (referring to the side extending beyond the guide opening 120 toward the limit opening 130 when viewed from the direction of the handle 200) in the height direction of the cylinder 100, and the extension section 210 is connected to the side wall 110 of the cylinder 100. For example, the extension section 210 can be fixed to the outer wall of the side wall 110, or the extension section 210 can be fixed to the inner wall of the side wall 110. Through this design, the connection of the handle 200 can be completely fitted with the side wall 110 of the cylinder, so that the connection area between the handle 200 and the side wall 110 of the cylinder is larger and more secure.

[0065] In one embodiment, the extension section 210 is fixed to the inner wall of the side wall 110, so that when the cup sleeve is arranged outside the cup body, the extrusion force applied by the cup body to the inner wall of the cup sleeve will be applied to the extension section 210, which will increase the connection pressure between the extension section 210 of the handle 200 and the side wall 110, which is conducive to a more secure connection between the handle 200 and the side wall 110.

[0066] The extension length of the extension section 210 is not limited. For example, the extension section 210 may extend beyond the guide opening by 10 mm, 20 mm, etc. Specifically, the distance that the extension section 210 extends beyond the guide opening 120 may be less than one-fourth of the height of the cylinder 100. In this way, the cup sleeve as a whole can achieve connection strength while also having good overall aesthetics. For example, if the extension section 210 is too large, the cup sleeve as a whole will appear too bulky. If the extension section 210 is too small, the connection area between the handle 200 and the cylinder 100 will be small, affecting the connection stability of the handle 200.

[0067] The material of the barrel 100 and the handle 200 is not limited, for example, it can be plastic, paper, non-woven fabric, etc.

[0068] In one embodiment, the barrel 100 and the handle 200 are both made of non-woven fabrics. Both ends of the handle 200 are fixed to the side wall 110 by heat sealing means, and the sealing portion 111 is also formed by heat sealing means, which can be formed by ultrasonic hot stamping.

[0069] In another embodiment, the cylinder 100 and the handle 200 may both be made of paper sheets, and both ends of the handle 200 may be glued to the side wall 110 of the cylinder 100 , and similarly, the sealing portion 111 may also be sealed by gluing.

[0070] In another embodiment, the cylinder 100 and the handle 200 may also be made of different materials, for example, the cylinder 100 may be a non-woven fabric, and the handle 200 may be a paper rope; the cylinder 100 may be a paper material, and the handle 200 may be a non-woven fabric belt, etc. The sealing portion 111 of the non-woven cylinder 100 may be ultrasonic heat-sealed, the sealing portion 111 of the paper cylinder 100 may be glued, and the handle 200 and the cylinder 100 may be glued and fixed.

[0071] As mentioned above, the cup sleeve provided by the utility model can be applied to various conical cups such as milk tea cups and coffee cups, and the cup sleeve not only has a simple manufacturing process and saves materials through the above design, but also has extremely strong structural stability. It can reduce the manufacturing cost of the cup sleeve and improve the structural stability of the cup sleeve during use while taking into account heat insulation and ease of carrying.
