The present invention relates to a heat-insulating cup, in particular to a multi-lid heat-insulating cup which can conveniently perform heat insulation for a pop can or beer bottle.
Traditional heat-insulating cups are only used for drinking tea and water. In many occasions, such as drinking while working, or needing to slowly sip canned or bottled iced beverage (such as cola and beer) in a leisure environment, as time passes by, temperature of the beverage will quickly increase due to ambient temperature, and the mouthfeel of the beverage will soon become compromised. Moreover, condensed water formed on a can or bottle body flows down along the body, and contaminates documents and devices. In addition, such traditional heat-insulating cups are prone to shake and cause the beverage to splash out when fixing a canned or bottled beverage.
In view of the aforementioned current situation, some people invented, for example, a “Dual-purpose Heat-Insulating Cup” under the CN utility model patent number ZL202021395246.0 (publication number CN212939250U), which discloses a heat-insulating cup, including a cup body and a fixing ring fixed at an opening of the cup body, where the cup body is a vacuum cup body, the inner wall of the cup body is stepped, and the inner wall of the opening of the cup body is provided with an internal thread. Since the vacuum cup body is adopted, and the inner wall of the cup body is stepped, the diameter of an upper section of an inner space of the cup body is greater than that of a lower section, so that a heat insulation effect of the heat-insulating cup can be ensured, and the heat-insulating cup can adapt to pop cans of different sizes; when the fixing ring sleeves the opening of the cup body, heat insulation can be performed on the canned or bottled beverage, if the fixing ring replaced with a cup lid mating with the internal thread at the opening of the cup body, the heat-insulating cup can be directly used for drinking tea or water, so that the heat-insulating cup has a wider range of applications; the fixing ring is made of elastic silica gel, the fixing ring is provided with a fastening ring around the center of the circle, and the inner wall is provided with anti-slip patterns, which can fix the pop can so that the pop can will not shake easily.
However, when the pop can is placed in the aforementioned heat-insulating cup, a top end of the pop can is completely exposed, which affects the heat insulation effect for the pop can. Moreover, after the pop can is opened, the beverage will lose its fizz and go flat fast as a drinking port is exposed all the time.
The technical problem to be solved by the present invention is to provide, in view of the current situation of the prior art, a multi-lid heat-insulating cup which is rational in structural design and convenient for performing heat insulation on a pop can, and the heat-insulating cup can enclose the pop can for heat insulation and can also serve as a conventional heat-insulating cup.
The technical scheme adopted by the present invention to solve the above technical problems is: a multi-lid heat-insulating cup, including a heat-insulating cup body with an accommodating cavity and a cup lid detachably connected to the heat-insulating cup body, the cup lid being provided with a drinking mouthpiece and a drinking mouthpiece lid being disposed at the drinking mouthpiece, where an inner top surface of the cup lid is provided with a ring-shaped sealing gasket; and with the cup lid covering an opening end of the heat-insulating cup body, the sealing gasket is capable of sealing both the opening end of the heat-insulating cup body and a top periphery of a pop can placed in the accommodating cavity, and a beverage outlet of the pop can is in communication with the drinking mouthpiece.
Further, as an improvement, an inner wall of the heat-insulating cup body is provided with one or more step portions, such that a diameter of an upper section of the accommodating cavity is greater than that of a lower section. This structure can accommodate pop cans of different sizes.
Optionally, the drinking mouthpiece is configured to protrude upwards, the drinking mouthpiece lid is attached to the drinking mouthpiece by a threaded or snap-fit connection, and an inner end surface of the drinking mouthpiece lid is provided with a sealing ring which forms sealing with an opening end of the drinking mouthpiece. The drinking mouthpiece is configured to protrude upward, which is convenient for users to drink, and the sealing ring is disposed to better prevent liquid leakage from the drinking mouthpiece.
Optionally, a connecting sheet is hinged to a top portion of the cup lid, the connecting sheet is provided with a mounting hole, and the drinking mouthpiece lid is constrained within the mounting hole and capable of rotating around its own axis. The connecting sheet connects the drinking mouthpiece lid and the cup lid together to prevent the drinking mouthpiece lid from being lost.
Still further, as an improvement, the cup lid includes an outer lid and a top lid, the outer lid being ring-shaped; the outer lid is attached to the heat-insulating cup body by a threaded or snap-fit connection; a top portion of an inner peripheral wall of the outer lid is provided with an inwardly extending stop ring; the top lid is detachably nested into the stop ring, a bottom surface of the top lid has a downwardly extending ring-shaped wall, a nesting groove in which the sealing gasket is to be nested is formed between an outer periphery of the ring-shaped wall and the inner peripheral wall of the outer lid, and the drinking mouthpiece is disposed on the top lid and is in communication with a space defined by the ring-shaped wall. With this structure, the top lid part can be detached from the outer lid, after the top lid is detached, the existing heat-insulating cup structure for the pop can is realized, the top end is open and enables placement of a beer bottle, and the beer bottle can penetrate the outer lid upwards.
Further, as an improvement, an outer periphery of the top lid and an inner wall of the stop ring are detachably attached to each other by a snap-fit connection through a rib-groove configuration. A snap-fit constraint is formed between the top lid and the inner wall of the stop ring, such that a considerable force has to be exerted to detach the top lid from the outer lid, that is, the top lid is prevented from being easily detached from the outer lid.
As an improvement, a bottom portion of the outer periphery of the ring-shaped wall is provided with an outwardly extending stop, and the stop forms a position limitation on a bottom surface of the sealing gasket. The stop is configured to further limit the sealing gasket, such that the combination of the sealing gasket and the cup lid is more robust.
In order to further firmly combine the sealing gasket with the cup lid, a top surface of the sealing gasket is provided with a plurality of upwardly extending elastic catches, the top lid is provided with recesses, and the elastic catches are snap-fitted in the recesses.
Further, as an improvement, a top surface of the outer lid is fixedly provided with a ring-shaped limiting member made of a flexible material, and an inner edge of the limiting member protrudes radially inward from a peripheral wall of the stop ring. The limiting member plays a role in retaining and decorating the top lid, and more importantly, when the top lid is detached, the inner edge of the limiting member makes frictional contact with the peripheral wall of the beer bottle penetrating the outer lid, thereby retaining the beer bottle.
Optionally, the limiting member is integrally formed with the outer lid. Of course, ultrasonic welding can also be used.
Compared with the prior art, the present invention has the advantages: on the basis of the existing heat-insulating cup body, the cup lid which can cover an opening of the heat-insulating cup body is disposed to increase a heat insulation effect, and the sealing gasket is disposed to form sealing with the top periphery of the pop can placed in the accommodating cavity, so that the beverage flowing out from a drinking mouthpiece of the pop can is prevented from flowing into the heat-insulating cup body, and a beverage outlet of the pop can is in communication with the drinking mouthpiece, without affecting drinking of the beverage.
The present invention will be further described in detail with reference to the accompanying drawings and embodiment.
