Abstract
Current designs of dispensers often do not allow for proper ventilation. Additionally, current designs often do not permit proper liquid sealing during shipment. The disclosed apparatus can overcome these shortcomings. This foam dispenser comprises a container, a cylinder device, a collar connected to the cylinder device, the collar operably connecting the container with the cylinder device, and a seal located on the collar, wherein the seal expands under compression to a locked position to create an airtight and liquid tight seal substantially preventing air and liquid from entering or exiting the cylinder device.
