Abstract: A breast pump adapter including a body, hooks, and wings. The body includes a top end that is configured to attach to a nozzle of a breast pump. The hooks extend outwardly from the body. Each hook is configured to be received in an aperture of a bag. The wings extend outwardly from the body. Each wing tapers from the body to a respective distal end.

Abstract: A plastic bag includes a front wall and a rear wall that are joined together to define a containment portion. To facilitate pouring a pourable substance from the containment portion, the plastic bag includes a pour spout. The pour spout includes an aperture that is defined in a lip. The lip can be formed into a channel such that the pourable substance is directed through the aperture. The plastic bag also includes a series of ribs that are formed in the region where the bag is folded to define a bottom end. The ribs reinforce the bottom end without compromising the flexibility of the bottom end.

Abstract: A plastic specimen bag (10) includes a front wall (20) and a rear wall (22) that are joined together to define a containment portion (32) having a bottom (24), side edges (26, 28), and a top opening (30). The plastic specimen bag (10) further includes a first closure (C1) located between the bottom (24) and the top opening (30) for selectively closing the containment portion (32). To facilitate opening the specimen bag (10), the specimen bag (10) includes a first grip enhancing profile (50) and a second grip enhancing profile (52) that are formed in the front wall (20) and spaced apart from one another to define a tear area (54) therebetween. The tear area (54) is located between the closure (C1) and the bottom (24).
