Patent NZ-710692-A (NZ)
Title: Expandable gravity-feed bin
Inventor: JOHNSON SCOTT
IPC: B65D21/08
Filed: 2014-01-06
Abstract: The present invention relates generally to a bulk-product inventory dispensing apparatus and, more particularly, to a gravity-feed dispensing apparatus with an expandable reservoir. Heretofore, gravity-feed bins have been provided with a reservoir having one of several fixed capacities. This limits the quantity of bulk inventory that is available for dispensing, particularly if the bulk inventory to be dispensed is relatively large or is a popular item. As a result, such inventory may be rapidly depleted. A gravity-feed bin (10) according to one aspect of the invention includes a generally hollow main bin (12) that has a storage reservoir (14) and an open end (32). A first generally hollow extension section (30) is selectably coupled to the open end (32) of the main bin (12). The first extension section (30) is in communication with the reservoir (14), and the storage capacity of the reservoir (14) is increased by the first extension section (30). In some embodiments a seal element (34) is intermediate the open end (32) of the main bin (12) and the first extension section (30), the seal element (34) providing a substantially air-tight seal between the main bin (12) and the first extension section (30). A plurality of extension sections (30) and seal elements (34) may be selectably coupled together in a stacked arrangement upon the main bin (12) to increase the storage capacity of the reservoir (14).

Title: A water jet for a showerhead
Inventor: YONGHUA TANG
IPC: B05B1/12
Filed: 2017-05-05
Abstract: The present invention provides a showerhead 100, and a water jet 200 for a showerhead, that is specifically configured to aerate at least some of the water passing through the water jet. The water jet 200 comprises a water passage, an air passage 206, an outlet for the aerated foamy water, a first conduit 204 linking the water passage to the air passage 206 to aerate the water, and a second conduit 208 linking the air passage 206 to the outlet. The first conduit 204 has a central vertical axis 204a and the second conduit 208 has a central vertical axis that is substantially in line with the central vertical axis of the first conduit 204. The first conduit tapers outwardly from its central vertical axis 204a along a portion of its length in a downstream direction and defines a flow path for water passing therethrough. The second conduit 208 tapers inwardly towards its central vertical axis along a portion of its length in a downstream direction, and has a first section 208b and a second section 208c, where the first section 208b has a reduced inward taper relative to the second section and includes an impact area for water travelling along the flow path to further aerate the water. The water jet may require less precision in manufacturing tolerances and may be a more cost-effective solution for producing a softer flow of water compared to prior art arrangements. The invention has particular application for handheld showerheads which have multiple spray arrays.
