Description

Technical Field

[0001] The present invention relates to the technical field of packaging, in particular to the technical field of beverage packaging, and in particular to a resealable heat-insulating beverage cup and a cup cover. Background Art

[0002] Beverage packaging is widely used in people's daily life. It is through various beverage packaging that a variety of beverage products enter people's daily life in various forms. Beverage cups are the main packaging for beverage takeout and dine-in, but there are still some problems with the beverage cup packaging currently on sale.

[0003] First, the sealing effect and reuse of beverage cups. Although some existing beverage cups are also designed with sealing lines, they are basically distributed on the edge of the inverted container or the edge of the lid. The liquid remaining in the gap between the edge of the cup and the edge of the lid cannot flow back into the cup. As time goes by, it is easy to leak out of the package, or spill out at the moment of opening the lid, causing pollution; the problem that needs to be paid attention to is that sealing requires stable and continuous contact stress. Existing beverage cups and cup lids basically use a buckle structure, which is difficult to ensure the contact stress between the sealing line and the sealing wall, so it cannot produce a good sealing effect. It is easy to loosen during transportation or use, resulting in leakage and a bad user experience; and these sealing solutions are difficult to buckle again and ensure the sealing effect after opening, and they are not suitable for reuse.

[0004] Secondly, there is the problem of heat insulation of beverage cups. Existing beverage cups use a smooth single-layer structure with thin walls. They conduct heat quickly, which makes the hands hot when drinking hot drinks and cold when drinking cold drinks. The user experience is not ideal. The reason is that there is no reasonable heat insulation structure. If heat insulation ridges are simply added to the cup body, the stacking height may increase significantly, the storage and transportation efficiency may decrease significantly, and the operating cost may increase, which is not cost-effective.

[0005] Thirdly, the design of the cup lid is complicated. Beverage products need to consider different usage scenarios, such as direct drinking and drinking with a straw. For this reason, some cup lids are only designed with a direct drinking port, but most cup lids are designed with two openings, namely the straw port and the direct drinking port. Those cup lids designed with a single direct drinking port cannot take into account the scenario of using a straw, and the cup lids designed with two openings are not only complex in structure, but also increase the risk of leakage by adding an opening. At the same time, they cannot be re-sealed after opening, which affects reuse.

[0006] Currently, there is a lack of a technical solution for reusable, heat-insulating, ventilated and sealed beverage cups and cup lids that can improve consumer experience while taking into account environmental performance and reducing plastic waste. Summary of the invention

[0013] Further preferably, the heat-insulating protrusions include a plurality of protrusion patterns or designs whose axial height is smaller than the side height of the small platform.

[0014] The present invention also provides a resealable cup lid, comprising a lid edge, a lid side, a lid top and a protective sheet; the lid edge is provided with a lid thread, which cooperates with the cup thread to form a threaded connection structure to connect the beverage cup and the cup lid; a sealing ring is provided inside the lid edge, and the sealing ring includes an outward annular sealing wall; when the beverage cup and the cup lid are matched, the annular sealing wall is inserted into the inner wall of the cup edge to form an interference fit internal plug-in sealing structure.

[0015] Further preferably, the insertion depth H of the internal plug-in sealing structure is between 0.5 mm and 9 mm.

[0016] Further preferably, an exhaust cavity is provided under the protective sheet, including a recessed portion provided on the top of the cover and a section of the protective sheet, which together form an exhaust cavity, a lower exhaust hole is provided at the lowest position inside the exhaust cavity, and an upper exhaust hole is provided at the highest position of the exhaust cavity.

[0017] Further preferably, the top of the lid is provided with a direct drinking straw opening protruding from the top of the lid and the side of the lid, which has the dual functions of a drinking opening and a straw opening; the direct drinking straw opening is circular, oval, or oval, and the protective sheet is connected to the top of the lid, and at least one end is provided with a plug, and when matched with the cup lid, the plug is inserted into the direct drinking straw opening to form an interference fit internal plug-in sealing structure.

DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other; the described embodiments are only embodiments of a part of the present invention, not all of the embodiments; in addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0023] The series of embodiments of the present application and the features contained therein can be applied to various technical solutions for beverage packaging. In particular, when packaging some hot or cold beverages, the application of the present invention can achieve multiple functions such as repeated sealing, heat insulation, and leak prevention, while not affecting stacking, and can achieve efficient storage and transportation, and improve logistics efficiency. The above objectives can be achieved by applying any of the series of embodiments of the present application. The series of embodiments of the present application can also be applied to any other scenarios that require repeated sealing, heat insulation, and leak prevention in the foreseeable future.

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] First, several definitions used in the present invention are explained: the plane passing through the central axis of the beverage cup is the axial section; the table bodies involved in the present invention are all inverted tables that are larger on the top and smaller on the bottom, so the axial section and the two sides of the side of the table body can form two intersection lines respectively, and the angle between the two intersection lines is an acute angle opening upward. The smaller the angle, the closer the side of the table body is to vertical, and the larger the angle, the more inclined the side of the table body is. In the present invention, this angle is defined as the roll angle, such as the angle α in the figure.

[0026] See also Figures 1 to 6 , Specific embodiment 1, a resealable insulated beverage cup and cup cover, including a beverage cup and a cup cover.

[0027] The beverage cup comprises a cup rim 3 , a cup body 2 and a cup bottom 1 .

[0028] The cup body 2 includes two inverted table side surfaces, and the angle between the two intersection lines of the axial section and the table side surfaces is the inclination angle α. In this embodiment, the inclination angles α of the two table side surfaces are different and are both greater than 2.6 degrees. The inclination angle α1 of the upper table side surface is smaller than the inclination angle α2 of the lower table side surface, that is: 2.6 degrees < α1 < α2.

[0029] The insulation protrusion is a solid insulation rib 2.1, which is arranged on the lower side of the platform with a larger inclination angle; the insulation rib 2.1 is arranged in a straight line on the side of the platform, and any insulation rib has a symmetrical middle surface perpendicular to the bottom surface; of course, as a variable design, the arrangement direction of the insulation rib can also be changed, as long as the demoulding problem is taken into account.

[0030] The cup rim 3 is provided with a cup thread 3.1, which is used to cooperate with the cup cover to form a threaded connection structure to connect the beverage cup and the cup cover.

[0031] The cup cover comprises a cover edge 5, a cover side 7, a cover top 6 and a protective sheet 9; the cover edge 5 is provided with a cover thread 5.1, which cooperates with the cup thread 3.1 to form a threaded connection structure to connect the beverage cup and the cup cover; a sealing ring 5.2 is provided inside the cover edge, and the sealing ring comprises an outward annular sealing wall 5.3. When the beverage cup and the cup cover are buckled together, the annular sealing wall 5.3 is inserted into the inner wall 3.2 of the cup edge to form an interference fit internal plug-in sealing structure.

[0032] For the insertion depth H of the inserted sealing structure, the more optimal setting is between 0.5 mm and 9 mm. The insertion depth H of this embodiment is designed to be about 3 mm. Of course, if the insertion depth is deeper, the sealing performance will be better, but if it is too deep, it will be difficult to demold. On the contrary, if it is too shallow, for example, less than 0.5 mm, the sealing effect will be poor.

[0033] An exhaust cavity 8 is also provided below the protective sheet 9, including a recessed portion 6.5 provided on the top of the cover and a section of the protective sheet 9, which together form an exhaust cavity 8, a lower exhaust hole 6.7 is provided at the lowest position inside the exhaust cavity, and an upper exhaust hole 9.7 is provided at the highest position of the exhaust cavity 8.

[0034] The lid top is provided with a direct drinking straw port 6.3 protruding from the lid top and the lid side, which has the dual functions of a drinking port and a straw port; the direct drinking straw port 6.3 is oval, ergonomic, and comfortable to drink from. Of course, as a variation of the design, it can also be round or oval, both of which can achieve the desired effect. The protective sheet 9 is connected to the lid top 6, and at least one end is provided with a plug 9.3. When the protective sheet 9 is matched with the cup lid, the plug 9.3 is inserted into the direct drinking straw port 6.3 to form an interference fit internal plug-in sealing structure.

[0035] In this embodiment, the protective sheet 9 is provided with two bending portions 9.5. Of course, the design of one or more bending portions can also be changed according to the shape of the protective sheet, and similar effects can be achieved; the protective sheet 9 is also provided with a locking notch 9.8 and a locking protrusion 9.9, which are detachably connected. When the direct drinking straw opening 6.3 is opened, one end of the protective sheet 9 with the plug 9.3 rotates around the bending portion, so that the locking notch 9.8 and the locking protrusion 9.9 are close to each other and connected, so as to fix the movable end of the protective sheet 9 to prevent it from interfering with drinking and affecting the consumer experience when it is active.

[0036] This embodiment adds a heat-insulating function to the beverage cup by setting a straight heat-insulating rib, and solves the problem of stacking caused by the structure of the heat-insulating rib by designing two sections of the platform side with different side inclination angles, so that this embodiment can take into account the stacking problem while setting the heat-insulating rib, which not only increases the practical function but also solves the problem of logistics efficiency; the setting of the plug-in sealing structure in this embodiment optimizes the sealing effect, and combined with the setting of the threaded connection structure, it further strengthens the sealing effect, and at the same time realizes the function of repeatable sealing, which provides convenience for the reuse of the beverage cup.

[0037] See also Figures 7 to 9 , Specific embodiment 2, a resealable insulated beverage cup and cup cover, including a beverage cup and a cup cover.

[0038] The beverage cup comprises a cup rim 3 , a cup body 2 and a cup bottom 1 .

[0039] The cup body 2 includes two inverted table side surfaces, and the angle between the two intersection lines of the axial section and the table side surfaces is the inclination angle α. In this embodiment, the inclination angles α of the two table side surfaces are different and are both greater than 2.6 degrees. The inclination angle α1 of the upper table side surface is smaller than the inclination angle α2 of the lower table side surface, that is: 2.6 degrees < α1 < α2.

[0040] The insulation protrusion is a solid insulation rib 2.1, which is arranged on the lower side of the platform with a larger inclination angle. The insulation rib 2.1 is arranged in a spiral shape on the side of the platform. As a variable design scheme, the shape of this insulation rib can also be changed in various forms, and can be designed with a combination of straight lines, spiral lines, or other curves. As long as the demoulding problem is taken into account, it can become an effective design scheme.

[0041] The cup rim 3 is provided with a cup thread 3.1, which is used to cooperate with the cup cover to form a threaded connection structure to connect the cup body and the cup cover.

[0042] The cup cover comprises a cover edge 5, a cover side 7, a cover top 6 and a protective sheet 9; the cover edge 5 is provided with a cover thread 5.1, which cooperates with the cup thread 3.1 to form a threaded connection structure to connect the beverage cup and the cup cover; a sealing ring 5.2 is provided inside the cover edge, and the sealing ring comprises an outward annular sealing wall 5.3. When the beverage cup and the cup cover are buckled together, the annular sealing wall 5.3 is inserted into the inner wall 3.2 of the cup edge to form an interference fit internal plug-in sealing structure.

[0043] For the insertion depth H of the inserted sealing structure, the more optimal setting is between 0.5 mm and 9 mm. The insertion depth H of this embodiment is designed to be about 3 mm. Of course, if the insertion depth is deeper, the sealing performance will be better, but if it is too deep, it will be difficult to demold. On the contrary, if it is too shallow, for example, less than 0.5 mm, the sealing effect will be poor.

[0044] In this embodiment, an exhaust cavity 8 is further provided below the protective sheet 9, including a recessed portion 6.5 provided on the top of the cover and a section of the protective sheet 9, which together form an exhaust cavity 8, a lower exhaust hole 6.7 is provided at the lowest position inside the exhaust cavity 8, and an upper exhaust hole 9.7 is provided at the highest position of the exhaust cavity 8.

[0045] The lid top is provided with a direct drinking straw opening 6.3 protruding from the lid top and the lid side, which has the dual functions of a drinking opening and a straw opening; the direct drinking straw opening 6.3 is oval, ergonomic, and comfortable to drink from. Of course, as a variation of the design, it can also be round or oval, both of which can achieve the desired effect. The protective sheet 9 is connected to the lid top 6, and at least one end is provided with a plug 9.3. When the protective sheet 9 is matched with the cup lid, the plug 9.3 is inserted into the direct drinking straw opening 6.3 to form an interference fit internal plug-in sealing structure.

[0046] In this embodiment, the protective sheet 9 is provided with two bent portions 9.5; the protective sheet is also provided with a locking notch 9.8 and a locking protrusion 9.9, which are detachably connected. When the direct drinking straw mouth is opened, one end of the protective sheet 9 with the plug 9.3 rotates around the bent portion, so that the locking notch 9.8 and the locking protrusion 9.9 approach each other and are connected, so as to fix the movable end of the protective sheet 9 to prevent it from interfering with drinking and affecting the consumer experience when it is moving.

[0047] The present embodiment provides a heat-insulating function for the beverage cup by providing a spiral heat-insulating rib, and solves the problem of stacking caused by the structure of the heat-insulating rib by designing two sections of the platform side with different side inclination angles, so that the present embodiment can take into account the stacking requirements while providing the heat-insulating rib, which not only increases the use function but also solves the problem of logistics efficiency; the provision of the plug-in sealing structure in the present embodiment optimizes the sealing effect, and combined with the provision of the threaded connection structure, it further strengthens the sealing effect, and can also achieve a repeatable sealing effect, which provides convenience for the reuse of the beverage cup.

[0048] See also Figures 10 to 12 , Specific embodiment 3, a resealable insulated beverage cup and cup cover, including a beverage cup and a cup cover.

[0049] The beverage cup comprises a cup rim 3 , a cup body 2 and a cup bottom 1 .

[0050] The cup body 2 is divided into an upper section and a lower section, the upper section is an inverted platform side, and the inclination angle is α1. The height of the upper platform can be adjusted arbitrarily according to the shape and capacity requirements of the cup, and it can also be a very small section in special cases; the lower section is composed of a group of inverted small platform sides, and the inclination angle of each small platform side is α3. In this embodiment, there are a total of nine small platform sides, and the heights of the small platform sides are (T1, T2, T3...), all of which are equal to the stacking height P; in the same axial section, the outermost points of the lowest positions of the nine adjacent small platform sides are connected to form a contour line of the platform side, and the inclination angle of the large platform side is α2, wherein α2 is greater than α3, and α3 can be very small, close to or equal to 2.6 degrees, and α1 is less than α2; in this embodiment, because the height of the small platform side is within the range of the stacking height, the stacking gap can be effectively utilized to set the insulation ribs without affecting the stacking effect. Of course, in order to seek some variations, the side inclination angles of the small platform bodies may be different, and their heights may also be different, thus producing some different designs.

[0051] The heat insulating protrusions 2.2 in this embodiment are nine groups of half-leaf-shaped patterns, arranged on the side surfaces of the nine small platforms; of course, the pattern of the heat insulating protrusions can be changed according to the product image design, thereby producing a variety of design solutions, as long as the demoulding problem is taken into account, they can all become effective design solutions.

[0052] The cup rim 3 is provided with a cup thread 3.1, which is used to cooperate with the cup cover to form a threaded connection structure to connect the cup body and the cup cover.

[0053] The cup cover comprises a cover edge 5, a cover side 7, a cover top 6 and a protective sheet 9; the cover edge 5 is provided with a cover thread 5.1, which cooperates with the cup thread 3.1 to form a threaded connection structure to connect the beverage cup and the cup cover; a sealing ring 5.2 is provided inside the cover edge, and the sealing ring comprises an outward annular sealing wall 5.3. When the beverage cup and the cup cover are buckled together, the annular sealing wall 5.3 is inserted into the inner wall 3.2 of the cup edge to form an interference fit internal plug-in sealing structure.

[0054] For the insertion depth H of the inserted sealing structure, the more optimal setting is between 0.5 mm and 9 mm. The insertion depth H of this embodiment is designed to be about 3 mm. Of course, if the insertion depth is deeper, the sealing performance will be better, but if it is too deep, it will be difficult to demold. On the contrary, if it is too shallow, for example, less than 0.5 mm, the sealing effect will be poor.

[0055] An exhaust cavity 8 is also provided below the protective sheet 9, including a recessed portion 6.5 provided on the top of the cover and a section of the protective sheet 9, which together form an exhaust cavity 8. A lower exhaust hole 6.7 is provided at the lowest position inside the exhaust cavity, and an upper exhaust hole 9.7 is provided at the highest position of the exhaust cavity 8.

[0056] The lid top is provided with a direct drinking straw port 6.3 protruding from the lid top and the lid side, which has the dual functions of a drinking port and a straw port. The direct drinking straw port 6.3 is oval, ergonomic, and comfortable to drink from. Of course, as a variation of the design, it can also be round or oval, both of which can achieve the desired effect. The protective sheet 9 is connected to the lid top 6, and at least one end is provided with a plug 9.3. When the protective sheet 9 is matched with the cup lid, the plug 9.3 is inserted into the direct drinking straw port 6.3 to form an interference fit internal plug-in sealing structure.

[0057] In this embodiment, the protective sheet 9 is provided with two bending portions 9.5, and the protective sheet 9 is also provided with a locking notch 9.8 and a locking protrusion 9.9, which are detachably connected. When the direct drinking straw opening 6.3 is opened, one end of the protective sheet 9 with the plug 9.3 rotates around the bending portion, so that the locking notch 9.8 and the locking protrusion 9.9 are close to each other and locked, so as to fix the movable end of the protective sheet 9 to prevent it from interfering with drinking and affecting the consumer experience when it is moving.

[0058] This embodiment adds a heat-insulating function to the beverage cup by providing a blade-shaped heat-insulating protrusion, and solves the problem of stacking caused by the structure of the heat-insulating ribs through the design of the multi-section small platform side, so that this embodiment can take into account the stacking requirements while providing the heat-insulating ribs, which not only increases the practical function but also solves the problem of logistics efficiency; the setting of the plug-in sealing structure in this embodiment optimizes the sealing effect, and the setting of the threaded connection structure further strengthens the sealing effect, and at the same time can achieve a repeatable sealing effect, which provides convenience for the reuse of the beverage cup.

[0059] In summary, it can be seen from several embodiments that as long as the side tilt angle of the cup body is reasonably designed, the space for arranging the heat-insulating protrusions can be cleverly reserved without affecting the stacking effect of the beverage cups, which can ensure both the heat-insulating function and the production and logistics efficiency; and the design of the plug-in sealing structure can well ensure the sealing effect, so that the liquid remaining within the sealing line can flow back into the cup to prevent leakage; the threaded connection structure can not only ensure the contact stress of the sealing structure, but also has a good reuse effect, so that consumers have the opportunity to reuse it, which plays a positive role in environmental protection; the drinking port and the straw port are combined into one, which greatly simplifies the cup cover structure, and the lack of an opening naturally reduces the risk of leakage, which is convenient to use and can greatly enhance the consumer experience. Each of the above embodiments includes or partially includes these features, that is, as long as these features are reasonably combined or selectively used or partially used, an optimized reusable heat-insulating beverage package can be designed, which can enhance the consumer experience while achieving the purpose of environmental protection.

[0060] The above are only optional implementation modes of the present invention. It should be pointed out that, for ordinary technicians in this technical field, it is possible to make several improvements and modifications based on the principles of the present invention without making any creative work. All other embodiments obtained thereby should be regarded as within the scope of protection of the present invention.
