Abstract
Description
Technical Field
[0001] This utility model relates to the field of disposable cup technology, and in particular to a disposable cup that is heat-insulating and not easily deformed. Background Technology
[0002] Disposable cups are convenient, inexpensive paper or plastic cups that are easy to carry and use. Milk tea shops and coffee shops commonly use disposable cups to serve hot drinks; after filling them, the top is simply sealed or a lid is put on. However, as temperatures drop, ordinary disposable cups have the following drawbacks when serving hot drinks:
[0003] Because ordinary disposable cups have a single-layer structure, they do not have heat preservation function. As a result, hot drinks cool down quickly after being filled with them, causing the drinks to get cold before they are finished, which affects the taste. Utility Model Content
[0004] The purpose of this utility model is to at least solve one of the technical defects described in the background art.
[0005] Therefore, one objective of this utility model is to provide a disposable cup that is heat-insulating and not easily deformed, in order to solve the problem that existing disposable cups do not have heat-insulating function, and hot drinks often cool down before they are finished when filled with them in cold weather.
[0006] To achieve the above objectives, one embodiment of this utility model provides a disposable cup that is heat-insulating and not easily deformed, comprising an inner liner, an outer shell, and a lid. The outer diameter of the opening of the inner liner is equal to the inner diameter of the opening of the outer shell, and the inclination angle of the sidewall of the inner liner is smaller than the inclination angle of the sidewall of the outer shell. The outer shell is fitted onto the outer surface of the inner liner. A first protrusion is fixedly connected to the top edge of the inner liner, and a second protrusion is fixedly connected to the top edge of the outer shell. A retaining ring is fixedly connected to the inner wall of the bottom end of the lid. The lid is fitted onto the outer surfaces of the first and second protrusions, and the retaining ring is engaged with the lower surface of the second protrusion. An insertion hole is provided on the top of the lid.
[0007] The beneficial effects are as follows: after the outer shell is placed on the surface of the inner liner, there is a gap between the outer shell and the inner liner, and the lid fixes the outer shell and the inner liner together, so it has a certain heat preservation performance. Therefore, when hot drinks are served in winter, the cooling time of the hot drinks can be delayed, thus avoiding the problem of the drinks getting cold before they are finished.
[0008] Preferably, in any of the above embodiments, the outer surface of the inner liner is fitted with a heat insulation sleeve, and the outer surface of the outer shell is provided with an indicator ring.
[0009] The beneficial effects are as follows: First, the gap between the outer shell and the inner liner makes it easy to deform the outer shell when it is directly squeezed after the inner liner is filled with hot drinks. However, the heat insulation sleeve is set between the inner liner and the outer shell, so the heat insulation sleeve can support the outer shell, making it less likely to deform when the outer shell is squeezed. The indicator ring also makes it easy to determine the specific part of the outer shell that is being squeezed. Second, when insulation is not needed in summer, the outer shell can be omitted, saving costs. When picking up the cup, the cup can be held by the heat insulation sleeve, so it will not be too hot to handle.
[0010] Preferably, as described in any of the above embodiments, the cup lid includes an inner lid and an outer lid, the inner wall of the bottom end of the outer lid is fixedly connected to the outer surface of the inner lid, and the retaining ring is fixedly connected to the inner wall of the bottom end of the inner lid.
[0011] The beneficial effects are: the lid has a double-layer structure with a gap between the inner and outer lids, which improves the heat preservation performance of the top of the cup and further delays the cooling time of hot drinks.
[0012] Another embodiment of this utility model provides a disposable cup that is heat-insulating and not easily deformed. The difference from the above embodiment is that the outer shell includes an inclined cylindrical section and a straight cylindrical section. The straight cylindrical section is fixedly connected to the top of the inclined cylindrical section. The second convex flange is fixedly connected to the top of the straight cylindrical section. The indicator ring is opened on the outer surface of the inclined cylindrical section. The inclination angle of the side wall of the inclined cylindrical section is equal to the inclination angle of the side wall of the inner liner.
[0013] The beneficial effects are as follows: the inner wall of the inclined cylindrical section of the outer shell is parallel to the outer wall of the inner liner, so the outer wall of the heat insulation sleeve can fit perfectly with the inner wall of the inclined cylindrical section. Thus, when the cup containing hot drinks is squeezed and handled, the heat insulation sleeve can provide stable support for the outer shell, making the outer shell less prone to deformation.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0024] This invention provides a disposable cup that is heat-insulating and not easily deformed.
[0025] Example 1:
[0026] like Figure 1-3 As shown, it includes an inner liner 1, an outer shell 2, and a lid 3. The outer shell 2 is fitted onto the outer surface of the inner liner 1. The outer diameter of the opening of the inner liner 1 is equal to the inner diameter of the opening of the outer shell 2, and the inclination angle of the side wall of the inner liner 1 is less than the inclination angle of the side wall of the outer shell 2. The inclination angle refers to the slope values of the side walls of the inner liner 1 and the outer shell 2 when the cup is inverted. This creates a gap between the outer shell 2 and the inner liner 1 after the outer shell 2 is fitted onto the surface of the inner liner 1, thereby improving heat retention. A fixed connection is made at the top edge of the inner liner 1. A first flange 11 and a second flange 21 are fixedly connected to the top edge of the outer shell 2. The first flange 11 rests on the second flange 21, which ensures that there is a certain gap between the bottom of the inner liner 1 and the outer shell 2, thereby further improving the heat preservation. A retaining ring 31 is fixedly connected to the inner wall of the bottom end of the cup lid 3. The cup lid 3 is fitted onto the outer surface of the first flange 11 and the second flange 21, and the retaining ring 31 is engaged with the lower surface of the second flange 21 to fix the cup lid 3. An insertion hole 32 is opened on the top of the cup lid 3 for inserting a straw.
[0027] Preferred, such as Figure 2 As shown, the outer surface of the inner liner 1 is fitted with a heat insulation sleeve 4. When the inner liner 1 is filled with hot drinks, the heat insulation sleeve 4 can support the inner wall of the outer shell 2 when the outer shell 2 is squeezed, so that the outer shell 2 is not easily deformed. In summer, when heat preservation is not required, the outer shell 2 can be removed from the inner liner 1 and hot drinks can be directly filled into the inner liner 1. The part of the hand holding the heat insulation sleeve 4 can avoid the problem of burning the hand. The outer surface of the outer shell 2 is provided with an indicator ring 22. The position of the indicator ring 22 corresponds to the position of the heat insulation sleeve 4, so that when the hand holds the outer shell 2, it is convenient to judge where the outer shell 2 needs to be squeezed.
[0028] like Figure 3 As shown, the cup lid 3 includes an inner lid 33 and an outer lid 34. The inner wall of the bottom end of the outer lid 34 is fixedly connected to the outer surface of the inner lid 33. The cup lid 3 has a double-layer structure with a gap between the outer lid 34 and the inner lid 33, which can further improve the heat preservation performance of the cup. The retaining ring 31 is fixedly connected to the inner wall of the bottom end of the inner lid 33.
[0029] Example 2:
[0030] like Figure 3-5 As shown, based on Embodiment 1, the difference from Embodiment 1 is that the outer shell 2 includes an inclined cylindrical section 23 and a straight cylindrical section 24. The straight cylindrical section 24 is fixedly connected to the top of the inclined cylindrical section 23, and the protruding edge 21 is fixedly connected to the top of the straight cylindrical section 24. The indicator ring 22 is opened on the outer surface of the inclined cylindrical section 23, and the inclination angle of the side wall of the inclined cylindrical section 23 is equal to the inclination angle of the side wall of the inner liner 1, so that the inner wall of the inclined cylindrical section 23 of the outer shell 2 is parallel to the outer wall of the inner liner 1. Therefore, the outer wall of the heat insulation sleeve 4 can perfectly fit with the inner wall of the inclined cylindrical section 23 of the outer shell 2, so that when the outer shell 2 is squeezed by hand, the heat insulation sleeve 4 can provide perfect support for the inclined cylindrical section 23, thereby making the outer shell 2 less prone to deformation.
[0031] The working principle of this utility model is as follows: In summer, since heat preservation is not required, hot drinks can be directly put into the inner liner 1, and then the opening of the inner liner 1 is sealed with plastic film. Finally, the heat insulation sleeve 4 is put on the outer surface of the inner liner 1 for use. In winter, when heat preservation is required, hot drinks are put into the inner liner 1, the heat insulation sleeve 4 is put on the outer surface of the inner liner 1, the inner liner 1 is then placed into the outer shell 2, the cup lid 3 is put on the top, and a straw is inserted into the socket 32.
