Definitions

  • thermo jugs for coffee, tea and other containers.
  • the invention is characterized in the way that the container changes form concerning how much fluid is in the container.
  • the word “container” represents all kind of thermo jugs and other opaque containers.
  • RODRIGUEZ KIMBERLY J US
  • RODRIGUEZ JIMMY US
  • U.S. Pat. No. 5,447,248 describe a thermo jug with a level indicator made of a glass pipe, which is connected in the top and the bottom to the rest of the container. The fluid level can be read on the outside of the container.
  • GB2332522 O'NEILL ROBERT ANDREW is another typical invention with at level indication made by a glass cylinder connected with the el kettle.
  • the isolation characteristic become worse if the fluids connect with a non isolated glass pipe situated on the outside of the container used for fluid level indication.
  • a “bypass” glasspipe makes it difficult to conduct proper cleaning and increases the danger of bacteria. This aspect can be disastrous when the container is use to contain drinking fluid, medicine, specimen, etc.
  • a small scale on a glass pipe can also be difficult to read from some distances.
  • a bypass construction will also make the container weaker for bumps and also less suited to contain fluids under pressure. And with this kind of construction it will necessary have at point of assemble between the pipe and the container. This could be a potential point of a leak.
  • the purpose of this invention is to present a solution that makes it visually possible to see from a distance how must fluid there is in the container.
  • the present invention is using the elementary principle that a containers weight varies with the amount of fluid the container is containing. This observation is used in the present invention to show the amount of fluid in the container by a simple weight measurement of the container.
  • the container/jug is placed on or hung one or more springs ( FIG. 2.B .) or other material with the same elastic characteristic.
  • the indicator of the fluid level is achieved by the inner containers position read in comparison to the outer container. ( FIG. 1.C .). As the container/jug is emptied, the weight decreases and the inner container will get a higher rest position and a further bigger part of the inner container (indicator) will be visible.
  • FIGS. 1 and 2 (left container) illustrate a jug filled with coffee (fluid).
  • the spring is calibrated in a way that the inner container (A) has a rest position, where it is nearly invisible and covered by the outer container (C).
  • FIGS. 1 and 2 illustrate a jug that is nearly empty.
  • the inner container now has a considerable lesser weight and a high rest position. It gives a visual effect indicating the amount of fluid in the jug and it will be possible to make that estimate at a distance.
  • the inner container position at full capacity can be marked on a scale on the outer container and so on for 3 ⁇ 4 1 ⁇ 2 and empty.
  • FIG. 3 Another design of the invention could be an “add-on” version ( FIG. 3 ).
  • a unit could be placed under existing jugs and alike.
  • the unit could be developed to specifics and popular models and could be prepared for permanent mounting on the thermo jugs. If this design version should be used to all types of thermo jugs, it must be able to calibrate the unit.
  • the advantages of the invention are the possibility from a distance to determine how much fluid the container/jug contains without shaking/lifting the jug, because the container/jug is changing form depending on how much fluid its contain.
  • the situation is well known with coffee and tee jugs, where people always ask “is there more coffee in the jug?”.
  • the invention will be a great advantage in catering, restaurants and hotel branchs. It will be a time saver for the waitress to be able to spot the jugs fluid level from a distance.
