Abstract: A compressed unit dose toilet cleaning tablet for use with a wand. The unit dose contains surfactant, organic acid, and an organic acid buffering agent and is compressed into a tablet or puck that dissolves in toilet water after cleaning. The tablet has a top surface, a bottom surface, a height extending from the top surface to the bottom surface, and a diameter. The top surface has an indentation adapted to receive and engage with a wand. A ratio of the height to the diameter of the tablet is between 0.2 and 0.3. A kit contains a plurality of the tablets and a wand.

Abstract: A cleaning system includes a dissolvable cleaner head and a wand for removable attachment to the cleaner head. The cleaner head has a top surface, a bottom surface, and a height extending from the top surface to the bottom surface and includes an indentation having a depth same as the height of the cleaner head. The wand has a first end, a second end, and an attachment arrangement movable between an engaged position, wherein the wand is removably coupled to the cleaner head, and a disengaged position, wherein the wand is released from the cleaner head. The cleaner head also has a first sealing member sealing against the top surface of the cleaner head when engaged with the attachment arrangement and a second sealing member sealing against an inner surface of the indentation when engaged with the attachment arrangement to impede liquid intrusion toward the attachment arrangement.

Abstract: A plastic bottle including a body portion, a neck portion extending from the body portion, and a plurality of equally sized and spaced ribs disposed around a circumference of the neck portion. The body portion can be configured to contain liquid. The neck portion can define an opening for dispensing liquid from the bottle and have a central axis. Each of the plurality of ribs can extend across an interface region between the neck portion and the body portion. Each of the plurality of ribs can extend across the interface region at an angle relative to the central axis of the neck. Each of the plurality of ribs can have a length of 1 mm to 10 mm.
