Description

Lid for sealing cup containing hot beverage The present invention relates to a lid for sealing a cup containing a hot beverage, the lid comprising means for cooperation with a cup rim in a pinch-tight manner, a lid surface extending substantially parallel to the cup rim when the lid is in cooperation with the cup rim, at least one support surface extending a distance from the lid surface and substantially parallel thereto, a disc-shaped baked product arranged to be supported above the lid surface and at a distance therefrom, one or more heat transfer apertures provided in the lid surface, a drinking opening, and a closure element, an assembly comprising a cup for containing a hot beverage and such a lid, and such an assembly comprising a disc-shaped baked product. Cups for holding hot beverages are well known in the art. In particular, disposable cups, also known as disposable cups, are often sealed by a lid that maintains beverage warmth for longer periods of time and reduces the risk of spillage. Such lids are clamped along the rim of a disposable cup, which is usually designed as a thickened rim, and a lid made of plastic or paper is clamped onto the rim by means of a snap connection. In fast food restaurants and beverage shops located at major transportation facilities such as gas stations, coffee is often sold in such packages and often accompanied by baked products such as syrup wafers, sandwich biscuits, cake pieces and the like. Syrup wafers are generally composed of two thin layers of baked dough with a caramel or syrup filling therebetween. Syrup wafers are often hard and difficult to bite without heating due to caramel or syrup crystallization. When heated, the syrup wafer is much softer, more intense tasting and easier to eat. US5,531,347 describes a lid of the above type in which a baked product such as a doughnut may be loosely placed on the lid. The lid may be closed with a closure member hinged to the periphery of the lid. The lid may be provided with a plurality of heat-conducting apertures or may be provided with preformed tabs which are removable by manual squeezing to form the heat-conducting apertures in the lid. When the cup contains a hot beverage, hot steam can flow through such heat conducting holes, thereby heating the doughnut. One or more of the tabs may be opened as desired before the donuts are placed on the lid. Once the donuts are placed on the lid, heat transfer is no longer controlled. In addition, the cup must then be placed upright and carefully moved to prevent the doughnut from sliding off the lid. WO2018/065752 describes a lid for sealing a cup having a plurality of radially positioned drinking openings that can be closed with a removable disc-like sealing element. This lid is not suitable for holding a disc-shaped baked product. US8,684,221 describes a lid on which a baked product, such as a syrup wafer, can be placed, which baked product can be heated with hot air or steam from a hot beverage. However, there are a number of disadvantages to such caps. For example, the lid must be removed to drink the beverage. Removing the lid when it is clamped to the rim of the cup can be cumbersome. Because the baked product is simply placed on the lid at will, it must be removed from the lid and set aside to remove the lid. After one or more beverages have been consumed, the lid must be replaced before the baked product can be replaced on the lid. This is very cumbersome and there is a risk of spillage and especially scalding when the beverage is hot. In addition, placing baked goods aside can also affect sanitation. Moreover, the degree of heating of the baked product is not controlled. In the case of syrup wafers, it is important to be able to control the degree of heating. If heated too much, the wafer will soften and there is a risk that caramel or syrup will become too thin and drip out of the wafer. In addition, the wafer with overheating may also have poor mouthfeel and be more difficult to take. WO2019/229481 describes a lid with a high flange forming a chamber in which a baked product such as croissants can be held. And the sealing element closes the top of the chamber. The lid has no opening to allow hot vapor from the cup into the chamber. WO2017/034544 describes a perforated lid through which water vapour can escape from a cup into a closed chamber in which snack foods can be contained. The top of the chamber is sealed with foil and is provided with a push-out element so that when the foil is opened the snack will pop up and be available for manual access. In such lids, the snack is placed directly on the perforated lid surface. The snack must be pre-packaged in the chamber at the factory and heated immediately after the lid is placed on the cup. The supply of steam is not regulated. The present invention aims at least partially to solve the above-mentioned problems and to provide a lid of the above-mentioned type by means of which, on the one hand, the beverage can b
