Description

Technical Field

[0001] The utility model relates to the technical field of cup covers, in particular to an injection-molded integrated cup cover. Background Art

[0002] Cups are common daily necessities in people's lives. In daily life, meetings, dinners, leisure and entertainment and other occasions, people pay more and more attention to drinking tea and coffee, and various cups with unique shapes have also appeared. Among all cups made of materials, glass cups are not only transparent and beautiful, but also the healthiest. Glass cups do not contain organic chemicals during the firing process. When people drink water or other beverages with glass cups, they don't have to worry about the chemicals being drunk into their stomachs.

[0003] Cups are usually equipped with cup lids, and the types of cup lids mainly include glass cup lids, plastic cup lids, and cup lids made of a combination of glass and plastic. In the prior art, when producing cup lids, especially when producing cup lids made of a combination of glass and plastic, the various components of the cup lids are usually produced separately and then glued and assembled together. The cup lids produced in this way are not strong enough and are prone to breakage at the bonding points. The glue is easy to volatilize under high temperature conditions and produce toxic and harmful substances, which endanger the health of users. At the same time, after glue bonding, glue marks are likely to remain on the outer surface of the cup lid, and the glue marks are not easy to remove. Removing the glue is time-consuming and laborious, affecting production efficiency. In addition, when glue is used for bonding, gaps may exist at the bonding points, affecting the thermal insulation performance of the product. Therefore, a stronger, healthier, injection-molded integrated cup lid with good thermal insulation performance that does not require glue removal and can improve production efficiency is proposed.
