    • A temperature controlled food service container is formed with an inner portion having side walls and an opening for the receipt of food, and an outer portion having sidewalls spaced from the inner portion with a eutectic gel, disposed between them. A ledge extends from the periphery of the outer portion with a flange extending from the inner portion seated against the ledge; and is held by an ultrasonic bond joining the ledge to the flange. The food container has ribs along the sidewalls of the inner and outer portions. Peripheral channels and ridges are formed respectively on the ledge and flange for welded engagement with each other, the channels having enlarged segments which extend beyond the cross-sectional dimension of a respective ridge received therein. The method for making the food service container includes molding an outer walled shell portion having a ledge with at least one peripheral channel, and molding an inner walled shall portion having a major peripheral flange with at least one peripheral protuberance. Thereafter a eutectic gel is placed into the outer walled shell portion and the inner walled shell portion is placed therein. The peripheral protuberance is indexed into the peripheral channel and the ledge and flange are ultrasonically bonded.
    • 一个温度控制的食品服务容器形成有一个具有侧壁和用于接收食物的开口的内部部分,以及设置在它们之间的具有与内部部分间隔开的具有共晶凝胶的侧壁的外部部分。 凸缘从外部部分的周边延伸出一凸缘,该凸缘从靠在凸缘上的内部部分延伸; 并且通过将凸缘连接到凸缘的超声波接合来保持。 食物容器沿着内部和外部的侧壁具有肋。 分别在凸缘和凸缘上分别形成外围通道和脊,以便彼此焊接接合,这些通道具有延伸超过其中接收的相应脊的横截面尺寸的扩大段。 制造食品服务容器的方法包括:具有至少一个周边通道的具有凸缘的外壁壳体部分,以及具有至少一个周边隆起部的具有主要周边凸缘的内壁部分。 此后,将一个共晶凝胶放置在外壁壳体部分中,并且将内壁壳体部分放置在其中。 周边突起被分配到周边通道中,并且凸缘和凸缘被超声波接合。
