20100065567 | TAMPER-EVIDENT CONTAINER WITH EXTENDED BAND - A container can include a base, a lid, and a tamper-evident, closed band. The base can define a space and an opening at a periphery, the opening can include at least one outwardly extending base flange, and the flange can have a contact surface. The base can also include a base sealing section. The lid can have a shape that generally matches the opening of the base generally at a periphery of the lid. The lid can also include at least one outwardly extending lid flange with a contact surface at the periphery, as well as a lid sealing section. The base sealing section and the lid sealing section can together form a reclosable snap fit when the lid is forcibly applied to the opening of the base to generally close the opening. Further, the base flange and lid flange can be in at least approximate alignment when the opening is closed such that the lid and base flanges can be manually pulled apart to separate the lid and base and overcome the snap fit. The lid and base flanges can also include a removed portion to create an increased distance between contact surfaces on the lid and base flanges at least one region. The tamper-evident, closed band can attach at a first end to one of the base and lid substantially along its entire periphery. At a second end, the band can have a free end. The tamper-evident band can be substantially detachable from the base or lid as a closed band. The band can also extend to substantially prevent direct manual access to the lid and base flanges. | 03-18-2010 |

20090140461 | MOLDING APPARATUS AND METHOD OF FORMING UNDERCUTS - A molding apparatus can include a primary mold, a stripper, and a swinging member. The swinging member can comprise a molding surface defining an undercut portion of a molded item. The swinging member can directly contact or attached to the stripper and the primary mold. To facilitate removal of a molded item, the swinging member can withdraw through a hole in the primary mold as a direct result of a motion of the stripper to pull the molded item off the primary mold. The molded item can then be easily removed. | 06-04-2009 |
