Abstract: The present disclosure relates to a cup cap 20 for a straw cup and a straw cup 1. The cup cap for the straw cup proposed herein comprises a cap body 30 and a movable cap 40 mounted on the cap body. The movable cap is movable between a closed position and an open position. The cap body is provided with a suction nozzle 34 and a normally closed valve 32. A guide track 46 is provided on a side of the movable cap facing the cap body. During a movement of the movable cap between the closed position and the open position, the guide track passes through the normally closed valve and applies a force to the normally closed valve to open the normally closed valve to balance the pressure inside and outside the straw cup. The present disclosure further provides a straw cup comprising such a cup cap. Embodiments of the present disclosure may prevent leakage, and may prevent hot water in the cup from spilling out from the suction nozzle and causing scald during the opening of the straw cup.

Abstract: The present invention relates to a pump arrangement (1) for a double breast pump (2). The pump arrangement (1) comprises first and second terminals (23, 24) for connecting first and second expression kits (3, 4) having first and second breast shields (5, 6) and at least one container (7) for collecting breast milk (8) in fluidic connection with the expression kits (3, 4), a pump (9) for generating reduced pressure within said breast shields, a plurality of conduits (10, 11, 14, 15, 16), a suction valve (12) connected to the pump (9) by a connection conduit (14) and to the first and second terminals (23, 24) by respective air conduits (10, 11), and a venting valve (13) connected to the first and second terminals (23, 24) by venting conduits (15, 16), wherein the venting valve (13) comprises an opening (17) to the environment. The pump (9) is alternatingly connected to the first and second terminals (23, 24) by alternate opening and closing of the suction valve (12) and the venting valve (13).
