Definitions

  • This invention relates to a small piston actuated dispensing pump made of molded or pressed parts of thermoplastic material and serving to discharge small amounts of liquid or paste out of a container, for'which the pump serves as a closure member, in which a tubular piston including an elastic sealing collar is guided within a pump cylinder and yieldingly urged outwardly by a spring so as to be operable from the outside, the pump cylinder being connected to the container by a cap, or the like, through which the tubular piston extends;
  • Some known pumps allow air to enter directly into the container due to the provision of suitable clearances for their parts relative to each other, but in this case the container is not tight any more, after the pump has been used, whereby a contents of pasty consistency may harden by the air admittance, or a liquid content may leak out of a horizontal or tilted container.
  • closure cap portion of the pump is provided with an elastic annular flange projecting with clearance into the cylinder and surrounding the tubular piston with suitable clearance so as to form an annular gap with the upper inner cylinder wall communicating through an aperture in the upper section of the cylinder wall with the inside of the container, and that in the resiliently outwardly urged position of the tubular piston the lower edge of the annular flange of the cap resiliently engages an annular conical surface of the piston to form a seal.
  • annular conical surface may, as will be explained in greater detail below, be a substantially rigid surface on the circumference of the shank of the tubular piston or may be formed by a corresponding surface section of the sealing collar of the piston.
  • FIGURE 1 is an elevational view in axial section showing a pump embodying the invention including an interiorly threaded closure member for use with a glass bottle or other container having an exteriorly threaded neck.
  • FIGURE 2 is a view similar to FIG. 1, illustrating a modified form of the invention, the closure member being arranged for use with the appropriately shaped top of a sheet metal container such as a can.
  • a first embodiment of a small piston pump according to the invention is shown in FIG. 1.
  • the pump is made of molded or pressed parts of thermoplastic material.
  • the pump comprises a cylinder 1, formed of thermoplastic material, and which has at its lower end a tubular extension serving to receive a thin-walled suction tube 2 extending down to substantially adjacent the bottom of the container on which the pump is mounted, and within the tubular extension a check valve 3 is arranged.
  • the cylinder 1 At its upper end the cylinder 1 is provided with a radial flange 1a, and in the corner formed between the cylinder Wall and the radial flange at least one aperture 4 is formed in the wall, the operation of which will later be explained.
  • a cap 7 is attached by snap action, or in any other suitable way, to the top end of the tubular piston 5.
  • the cap 7 is provided with a lateral channel 8 for the outlet of the container contents, if of pasty consistency, or with a nozzle (not shown) for spraying liquid contents.
  • the tubular piston 5 is guided by a lower sealing collar 9 slidable within the cylinder 1 and this collar 9 is formed by two oppositely extending lips with a tapering cross sectional shape which diverge upwardly and downwardly with obtuse angle, therebetween, the'lips being stressed to bear yieldingl against the inner wall of the cylinder 1.
  • the collar 9 may be formed of thermoplastic material integrally with the tubular piston 5, or as shown in FIG. 1, with an upwardly directed annular extension 10 fitted into an upwardly extending inner recessed bore at the lower end of the tubular piston 5 and provided, for example with circumferential retaining ribs, or other projections, which snap resiliently int-o corresponding grooves or recesses of the recessed bore wall.
  • tubular piston is, according to the invention, provided with a frusto-conical surface 11 diverging downwardly, the operation of which will be explained hereinafter.
  • the pump cylinder 1 together with the vertically reciprocable tubular piston 5, which is yieldingly urged upwardly by a helical compression spring 12 into its outwardly directed position of rest, may be connected in different Ways to the container 13. If the container 13 has an exteriorly threaded neck 14, as shown in FIG. 1, then the radial cylinder flange 1a seats on the upper edge of the container neck 14 and is then secured by an interiorly threaded cap 15, a cap screw, or the like. If the container 13 is provided with an aperture 17 in the cover surface 16, as shown in FIG.
  • annular cap 18 may be formed in such a way that the radial flange 1b of the cylinder 1 engages an inner groove 18a of the cap 18, while the cap is provided at the outer circumference with an annular groove defining edges which, after the cap has been pressed into the aperture 17, engage around the edge of the aperture.
  • the cap 15, or 18 respectively is also made of molded or pressed thermoplastic material, and is, according to the embodiment of FIG. 1, provided with an elastomeric annular flange 19 projecting into the interior of the cylinder and forming together with the outer circumference of the tubular piston an annular gap 20 tapering somewhat comically and preferably resiliently engaging with its lower end 19a the frusto-eonical surface 11 of the piston 5.
  • this flange 19 also defines an annular gap 21 around the inner wall of the cylinder 1 and which communicates via the aperture 4 in the cylinder wall with the interior of the container.
  • the cap 18 includes an elastic annular flange 19 projecting into the interior of the cylinder, but in this case it defines with the circumference of the piston 4 an annular gap 20a and with the upper part of the inner wall of the cylinder an annular gap 21a.
  • the cylinder wall in the upper part is provided with at least one aperture 4.
  • the tubular piston is in this case not provided with a rigid frusto-conical surface 11 as in FIG. 1, but this conical surface is, according to FIG. 2, formed by the upwardly divergent surface 22 of the upper lip of the obtuse-angled sealing collar 9 facing the shank 5 of the piston, and having walls tapering towards the outside and sealingly engage the inner cylinder wall under pretension.
  • a reciprocating piston pump for dispensing pumpable material out of a container, said pump comprising a closure cap for said container, a pump cylinder connected to said cap, check valve means arranged in the bottom of said cylinder, a suction tube extending from the bottom of said cylinder to a location adjacent to the bottom of said container, a tubular piston slidably guided within said cylinder and extending upwardly out of said cylinder, and outwardly through said closure cap, spring means arranged within said cylinder and said tubular pis ton yieldingly urging said piston upwardly into a normal position of rest, said piston being actuated from outside against the force of said spring means, an elastic sealing collar provided at the lower end of said tubular piston 'sealingly bearing against the cylinder wall, further check valve means arranged in the upper part of said tubular piston, means defining an outlet passage connected through said further check valve means to the interior of said tubular piston, an elastic annular flange formed integrally with said closure cap and projecting with clearance downwardly into said cylinder and
  • a small piston pump made of molded or pressed parts of thermoplastic material for discharging small amounts of liquid or paste out of a container, said pump comprising a cylinder attached to a closure cap of said container, suction valve means arranged in the bottom of said cylinder, a suction tube extending from the bottom of said cylinder to adjacent the bottom of said container, a tubular piston slidably guided within said cylinder and extending upwardly out of said cylinder, and outwardly through said closure cap, spring means arranged within said cylinder and said tubular piston urging said piston upwardly into its position of rest, said piston being actuated from outside against the force of said spring means, an elastic sealing collar provided at the lower end of said tubular piston formed by two annular lips with outwardly tapering walls extending in opposite direction so as to include an outwardly open obtuse angle, said lips sealingly bear against the cylinder wall, pressure valve means arranged in the upper part of said tubular piston controlling an outlet passage through said tubular piston, an elastic annular flange provided on said
