Mustard, ketchup and similar pasty matter is metered out and served from a dispenser, including a container and an attachable outlet pipe of flexible material enclosing a valve member. The container has one plane end face, permitting it to stand upright during storage, and an opposite, truncated end face, to which the outlet pipe is attached at a threaded portion. A restriction at the truncated end face defines a seat for a valve member, which includes an upper big body and a lower small body interconnected by a rod. The length of this rod is selected so the big body is held mainly inside the threaded container portion, but lower than its seat when the small body rests against the lower end of the outlet pipe.

A dispenser for fluids comprising a container and an outlet pipe of flexible material attachable thereto and receiving therein a valve member, comprising one big and one small body interconnected by a rod, said container having a substantially planar first end face and an opposite, truncated second

A dispenser for fluids comprising a container and an outlet pipe of flexible material attachable thereto and receiving therein a valve member, comprising one big and one small body interconnected by a rod, said container having a substantially planar first end face and an opposite, truncated second end face, said second end face terminating in a first externally threaded neck portion surrounding a first seat for said outlet pipe, means at said first end face for suspending said container in an upturned position with the engaged outlet pipe extending freely therefrom, a restriction in said second end face inside of said threaded neck portion forming a second seat for engagment by the big body of said valve member, said second seat being formed in one piece with the container, said outlet pipe having a top flange mating with said first seat, and an outlet opening at its opposite end, internally formed as a third seat for engagment by said small valve member body, an internally threaded annular member, mating with said first threaded portion and having a ledge for forcing said top flange against said first seat, said first seat being formed by a radially inwardly turned portion, which defines an opening having a diameter so as to permit introduction of the big valve body into a chamber located within the neck portion and defined by an inner wall of said threaded neck portion, the radially inwardly turned portion and the second seat, the length of the rod of said valve member being sufficient to hold said big body mainly within said chamber, when said small body rests upon said third seat, whereas the chamber forms a flow path around the big valve body, said outlet pipe having a tubular main portion of sufficient length to enable gripping and squeezing of the flexible pipe below the threaded annular member, said valve member being adapted to be influenced indirectly by fluid pressure in the pipe and lifted so as to apply its big valve body against said second seat and remove its small valve body from the third seat upon squeezing of the pipe.
