Description

Technical Field

[0001] This application relates to the field of cups, and more particularly to a paper cup. Background Technology

[0002] Paper cups are a necessity in daily life. Because they are safe, hygienic, and portable, they are used in various public service venues and even in households. However, due to their lightweight nature, paper cups are prone to tipping over. Furthermore, common paper cups, aside from the cup holder, lack additional storage space, making their function relatively limited. Utility Model Content

[0003] Therefore, it is necessary to provide a paper cup that is less prone to tipping over and can improve storage capacity.

[0004] This application provides a paper cup, which includes a cup cylinder and a base. The cup cylinder is shaped like a frustum with a large cross-sectional area at one end and a small cross-sectional area at the other end. The end of the cup cylinder with a small cross-sectional area has a rim, and the base is installed at the end of the cup cylinder with a large cross-sectional area. The base has a receiving groove with an opening facing away from the rim. The receiving groove is used to install and fix a spoon. The height of the receiving groove along the axial direction of the cup cylinder is h, where 3mm ≤ h ≤ 40mm.

[0005] In one embodiment, the base is shaped like a frustum of a cone with a large cross-sectional area at one end and a small cross-sectional area at the other end. The base is installed inside the cup and is bonded and fixed to the wall of the cup. It is understood that this arrangement allows the shape of the base to match the shape of the cup, thus facilitating the installation of the base inside the cup.

[0006] In one embodiment, the end of the base with the larger cross-sectional area has a slot that connects to the receiving groove. The slot is positioned away from the rim of the cup, and a mounting position is provided on the bottom wall of the receiving groove opposite the slot. The mounting position is used to fix the spoon. It is understood that this design makes it convenient for users to take the spoon out and put it in through the slot.

[0007] In one embodiment, the mounting position is configured as an adhesive layer coated on the bottom wall of the receiving groove; or, the mounting position is configured as a slot formed on the bottom wall of the receiving groove.

[0008] In one embodiment, the wall of the cup tube is folded inward at the end furthest from the rim, forming a sandwich space. The side wall of the base is sandwiched within this sandwich space and bonded to the wall of the cup tube. It is understood that this arrangement not only helps to further lower the center of gravity of the paper cup but also increases the bonding area between the cup tube and the base, making the connection between them more secure.

[0009] In one embodiment, the angle between the side wall of the cup and the axis of the cup is α, and 2° < α ≤ 10°. It is understood that this design not only helps to lower the center of gravity of the paper cup but also avoids affecting the user's ability to drink.

[0010] In one embodiment, the thickness of the base is greater than the thickness of the cup tube. It is understood that this arrangement helps to further lower the center of gravity of the paper cup, thereby improving its resistance to tipping.

[0011] In one embodiment, the cup rim has a rolled edge with a circular cross-sectional area and a diameter d, where 2.5mm ≤ d ≤ 5mm; or, the rolled edge has an elliptical cross-section. It is understood that this design prevents the cup rim from scratching the user, improving the user experience, and also increases the strength of the paper cup.

[0012] In one embodiment, one end of the rolled edge is connected to the cup tube, and the other end is rolled towards the inside of the cup tube.

[0013] In one embodiment, one end of the rolled edge is connected to the cup tube, and the other end is rolled towards the outside of the cup tube.

[0014] Compared to existing technologies, the paper cup provided in this application, by arranging the cup tube in a frustum shape with a large cross-sectional area at one end and a small cross-sectional area at the other, and with the smaller cross-sectional area end having a rim and the larger cross-sectional area end having a base, lowers the center of gravity of the paper cup, making it less prone to tipping over. It also helps prevent the contents of the paper cup from splashing out when it shakes. Especially when the paper cup is used to hold hot water, it also helps to reduce heat loss through the rim. By providing a receiving groove in the base for mounting and fixing a spoon, the storage function of the paper cup is expanded. Furthermore, when the spoon is mounted and fixed in the receiving groove, the center of gravity of the paper cup is further lowered, thereby further improving the anti-tipping ability of the paper cup.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0027] Please see Figures 1 to 2 This application provides a paper cup 100, which includes a cup cylinder 10 and a base 20. The cup cylinder 10 is a frustum-shaped structure with a large cross-sectional area at one end and a small cross-sectional area at the other end. The end of the cup cylinder 10 with a small cross-sectional area has a cup mouth 11, and the base 20 is installed at the end of the cup cylinder 10 with a large cross-sectional area. The base 20 has a receiving groove 21 with an opening facing away from the cup mouth 11. The receiving groove 21 is used to install and fix a spoon. Along the axial direction of the cup cylinder 10, the height of the receiving groove 21 is h, where 3mm≤h≤40mm.

[0028] By designing the cup 10 into a frustum shape with one end having a larger cross-sectional area and the other a smaller cross-sectional area, and with the smaller cross-sectional area end having a rim 11 and the larger cross-sectional area end having a base 20, the center of gravity of the paper cup 100 is lowered, making it less prone to tipping over. This also helps prevent the contents of the paper cup 100 from splashing out when it shakes, especially when the paper cup 100 is used to hold hot water, as it helps reduce heat loss through the rim 11. By providing a receiving groove 21 in the base 20 for mounting and fixing a spoon, the storage function of the paper cup 100 is expanded. Furthermore, when the spoon is mounted and fixed in the receiving groove 21, the center of gravity of the paper cup 100 is further lowered, thereby further improving the anti-tipping ability of the paper cup 100.

[0029] The setting is 3mm ≤ h ≤ 40mm. This allows for a wide range of height h in the receiving slot 21, accommodating various sizes of spoons. For example, when h is configured as relatively large values ​​such as 20mm, 30mm, 35.5mm, 37mm, and 40mm, the receiving slot 21 can be used to hold larger plastic spoons; when h is configured as relatively small values ​​such as 5mm, 6mm, and 10mm, the receiving slot 21 can be used to hold smaller wooden ice cream spoons. The specific value of h can be set according to actual needs, as long as h is within the above range, and will not be listed individually here.

[0030] Furthermore, the base 20 is shaped like a frustum with a large cross-sectional area at one end and a small cross-sectional area at the other end. The base 20 is installed inside the cup cylinder 10 and is bonded and fixed to the cylinder wall of the cup cylinder 10. That is, the shape of the base 20 is adapted to the shape of the cup cylinder 10, thereby facilitating the installation of the base 20 in the cup cylinder 10. In addition, the base 20 and the cup cylinder 10 overlap at least partially along their own axial direction, which helps to lower the center of gravity of the paper cup 100.

[0031] Optionally, the thickness of the base 20 is greater than the thickness of the cup cylinder 10. This helps to further lower the center of gravity of the paper cup 100, thereby improving the anti-tipping ability of the paper cup 100.

[0032] Alternatively, in one embodiment, as Figure 2 As shown, the base 20 has a slot 211 at the end with the larger cross-sectional area, which connects to the receiving groove 21. The slot 211 is positioned away from the cup opening 11, and a mounting position 212 is provided on the bottom wall of the receiving groove 21 opposite to the slot 211. The mounting position 212 is used to fix the spoon. This allows the user to easily install the spoon into the mounting position 212 through the slot 211 and to easily remove the spoon through the slot 211. However, this is not a limitation; in other embodiments, the slot 211 may also be provided on the side wall of the base 20.

[0033] Optionally, in one embodiment, the mounting position 212 is configured as an adhesive layer coated on the bottom wall of the receiving groove 21. In this embodiment, the spoon is bonded and fixed to the bottom wall of the receiving groove 21 by the adhesive layer. Specifically, the adhesive layer can be double-sided tape or glue.

[0034] Alternatively, in another embodiment, the mounting position 212 is configured as a slot formed in the bottom wall of the receiving groove 21. In this embodiment, the spoon is secured to the bottom wall of the receiving groove 21, thereby facilitating the user's handling.

[0035] like Figure 2 and Figure 4As shown, the wall of the cup cylinder 10 is folded inwards at the end away from the cup opening 11, forming a sandwich space 12. The side wall of the base 20 is sandwiched in the sandwich space 12 and bonded to the wall of the cup cylinder 10. That is, the cup cylinder 10 forms a double layer at the end with the larger cross-sectional area. This not only helps to further lower the center of gravity of the paper cup 100, but also increases the bonding area between the cup cylinder 10 and the base 20, making the connection between the cup cylinder 10 and the base 20 more secure. The cup cylinder 10 and the base 20 can be bonded together using a roll bonding process.

[0036] like Figure 2 As shown, the angle formed between the side wall of the cup cylinder 10 and its axis is α, and 2° < α ≤ 10°. It can be understood that, given the same height of the cup cylinder 10 and the same cross-sectional area of ​​the base 20, the larger α is, the greater the difference between the cross-sectional area of ​​the cup opening 11 and the cross-sectional area of ​​the base 20, resulting in stronger anti-tipping ability of the paper cup 100 and better heat retention. However, if α is too large, the cup opening 11 will be too small, making it inconvenient for the user to drink. Therefore, setting 2° < α ≤ 10° not only helps to lower the center of gravity of the paper cup 100 but also avoids affecting the user's drinking experience. For example, the value of α can be 2.5°, 3°, 3.5°, 5°, 9°, 10°, etc., as long as the value of α is within the above range; these will not be listed individually here.

[0037] like Figure 2 and Figure 3 As shown, the cup rim 11 is provided with a rolled edge 111. The rolled edge 111 is used to prevent the edge of the cup rim 10 from scratching the user, improving the user experience, and also increasing the strength of the paper cup 100.

[0038] In one embodiment, the cross-sectional area of ​​the rolled edge 111 is circular, and the diameter of the rolled edge 111 is d, where 2.5 mm ≤ d ≤ 5 mm. In another embodiment, the cross-section of the rolled edge 111 is elliptical.

[0039] Optionally, in one embodiment, one end of the rolled edge 111 is connected to the cup tube 10, and the other end is rolled towards the inside of the cup tube 10. That is, in this embodiment, the rolled edge 111 is located inside the cup tube 10.

[0040] In another embodiment, such as Figure 5 As shown, one end of the rolled edge 111 is connected to the cup cylinder 10, and the other end is rolled towards the outside of the cup cylinder 10. That is, in this embodiment, the rolled edge 111 is located on the outside of the cup cylinder 10.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0042] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
