Definitions

  • thermos bottles relate to the field of vacuum insulated containers of the type commonly referred to as thermos bottles. More specifically, it relates to an improvement in thermos bottle con- struction whereby the need to remove a cap to dispense the liquid therefrom is avoided. Since the purpose of a thermos bottle is to maintain its contents at a desired serving temperature, either hot in the case of coffee and the like or cold in the case of soft drinks, it is desirable to maintain the integrity of the vacuum unit to prevent hear transfer.
  • thermos bottle designs whether wide mouth or narrow mouth in construction, usually require that a cap be removed and the bottle be tipped to some degree to pour the contents from the bottle. During this dispensing operation the insulating properties of the bottle are impaired.
  • Another disadvantage of prior designs is that during pouring it is easy to spill the contents and if the liquid is hot, burns can result.
  • the invention provides-an improved vacuum bottle design which avoids the necessity for pouring liquids therefrom and which maintains the integrity of the temperature insulating bottle.
  • Pump units for vacuum bottles have been developed by others. These devices are highly complex employing a great number of components and being relatively more expensive to manufacture than the present invention.
  • the present invention achieves its simplicity through the use of a user controlled air intake and an efficient design whereby many of the components serves more than one function in the overall design.
  • a container having..a vacuum insulating filler, an outer protective jacket and a pouring opening through which liquids pass into and out of the interior of the container and a pump dispenser for said container adapted to removably engage the outer jacket of said container and seal the pouring opening to prevent heat loss and spilling, said dispenser including: means for pumping air into the container interior, means for preventing liquid in the container from entering said pumping means, and means for permitting liquid to pass out of the container when air pressure is increased in the container by the action of said pumping means.
  • the vacuum bottle for the purpose of the present application, includes an outer jacket 10,-a vacuum filler.12, a bottom cap 14 and a filler spacer 16 which positions the filler 12 in the jacket and protects the glass nipple through which air is withdrawn from the interior of the filler.
  • the filler is shown as being a narrow neck bottle, that is, one which tapers at its top to form a convenient pouring neck.
  • the pump dispenser according. to the invention is also capable of being used with wide mouth bottles. 'A wide mouth bottle does not have the taper and, accordingly, the pump dispenser would have a dimensional change to correspond to the opening of the wide mouth filler.
  • the pump 18, includes a dispensing spout 20, a spout channel 22 and a fluid tube 24 which extends downwardly into the interior of the thermos bottle. In response to air being forced into the interior of the thermos from the pump, fluid passes upwardly through the tube 24 into the channel 22 and out of spout 20.
  • Air is forced into the interior of the thermos by the manually operable pump portion of the unit which includes a disk 26, a flexible sealing member or pump diaphragm 28 and a return spring 30.
  • the disk 26 has an air port 32 located at its center for permitting the passage of air to an interior space 34 which is enclosed in part by the pump diaphragm 28.
  • the disk is retained in the position shown in Figure 2 by the inwardly directed flange 35 of a pump housing 36.
  • the disk 26 and diaphragm . 28 can, however, move vertically downward against the bias of a spring 30 to effect the pumping action to be described.
  • the spring 30 urges the disk and diaphragm back to their initial positions when manual pressure on the disk is removed.
  • the diaphragm 28 which has its outer end 29 secured between an upper portion 11 of the jacket 10 and a downwardly depending portion 37 of the housing 36, effectively seals the upper portion of interior space 34 to make it airtight except for opening 32 in the disk.
  • the inner surface of the diaphragm 28 is secured to the disk by any suitable bonding technique.
  • the lower portion of the space 34 is enclosed by a wall 39, a conical section 38, bottom 41, and a center post 40.
  • the upper portion of the center post 40 provides a means for mounting the helical spring 30.
  • Bottom portion 41 is provided with a number of openings 42 to permit the passage of air from the interior space 34 into the filler 12 in order to increase the air pressure on the surface of the liquid during pumping.
  • a gasket 44 encompasses the conical section 38 and bottom 41 of the pump housing. When the pump is secured over the filler 12 the gasket engages the top of the filler 12 to provide a fluid seal between the filler top and the conical section 38.
  • the central portion of the gasket has an aperture therethrough to permit the fluid tube 24 to pass downwardly into the bottle interior.
  • the gasket is retained in close proximity to the junction of the housing and the fluid tube. This securely covers the openings 42 to prevent the passage of liquid upwardly from the thermos into the interior space 34 ( Figure 4).
  • the lower portion of the gasket flexes away from the housing and fluid tube, as indicated in Figure 5, due to the air pressure generated by the pump unit. This permits the air to pass through the openings 42 and around the gasket end 50 into the interior of the thermos.
  • the gasket Upon completion of the pumping operation the gasket returns to its Figure 4 position to again seal the pumping unit.
  • the unit is secured to a thermos or other container for liquids by securing it-to the top in the manner illustrated in Figures 1 and 3.
  • the index finger or thumb of the user is placed over the opening 32 of the disk 26 thereby sealing the pump interior 34.
  • the user then applies downward pressure to the disk while maintaining the seal thereby forcing the air contained in the interior space 34 downwardly through the openings 42 into the interior of the vacuum bottle.
  • This air pres-. sure acts in a well understood manner to force the fluid in the container up the fluid tube 24 through the channel 22 and out the spout 20 to a cup or glass, as desired.
  • the gasket 44 alternately seals and unseals the openings 42 to prevent back flow of liquid while permitting entry of air to the container.
  • FIG. 9 and 10 a sealing arrangement according to a second embodiment of the invention is illustrated.
  • the gasket illustrated in Figures 9 and 10 is not in physical contact with the fluid tube 24. Instead, it is spaced slightly therefrom by virtue of having a slightly larger diameter aperture 71.
  • the following dimensions are exemplary of the type of relationship between the outside diameter of the fluid tube and the diameter of the aperture through the bottom of the gasket:
  • a gasket 70 is provided with a relatively thick tapering wall 72 aid a relatively thin bottom wall 74.
  • the opening 71 through the bottom of the gasket is defined by a circular bead 78 of increased dimension as compared to the bottom wall 74.
  • bead 78 is intended to normally maintain contact with the bottom portion 41 of the housing.
  • the holes 42 through the bottom portion 41 are located on the side of bead 78 opposite the tube 24 so that the bead normally provides a sealing relationship to prevent liquid from entering the pump interior through the holes 42.
  • the gasket When air is pumped, by operation of the disk and diaphragm, the resulting air pressure causes a slight flexing of bead 78 away from bottom portion 41 permitting air to pass into the vacuum filler to dispense the liquid contained therein.
  • the gasket should be formed of a.suitable material which will retain its initial shape so that it will return to the desired sealing position after each flexing away from the bottom of the housing.
  • suitable materials are available for this purpose and exemplary thereof is the material sold under the trademark LRATON.
  • the underside of gasket bottom 74 may taper upwardly and reduce in thickness (as viewed from the edge) to improve the flexing capability of the bead.
  • the angle of taper as measured from the edge, may be on the order of 3°. While this arrangement does not seal the pump unit against liquid as securely as the first embodiment does, it has the advantage of substantially reducing the amount of pressure required to operate the pump unit. This is due to the ease with which the gasket bead can be caused to flex away from the housing bottom 41 as compared to the pressure required to pass air around the gasket illustrated in Figures 4 and 5.
  • the pump housing 36 is provided with a plurality of guide ribs 52 spaced around its circumference. The ribs extend vertically substantially the entire length of travel of the disk between the positions illustrated in' Figures 2 and 3.
  • the disk 26 is provided with a corresponding set of grooves defined by projections 56 and 58 which mate with the guide ribs 52.
  • the pump unit may be provided with an internal thread 60 for engaging a mating thread on the jacket 10 of the thermos bottle.
  • the conical section 38 of the pump housing is dimensioned to securely seal on the filler opening so that as the threads are engaged the gasket 44 effects a good seal between the pump unit and the top of.the filler.
  • the threads 60 permit the pump housing to.engage the chermos bottle jacket quickly and conveniently to allow the pump unit to be attached to or removed from the thermos bottle for cleaning and refilling purposes.
  • this pump unit is designed for use with vacuum bottles or similar insulated containers, such as, foam bottles and the like.
  • Figure 8 illustrates the use of a pump unit according to the invention in conjunction with a quart container 64.which may be of the foam type or similar construction.
