DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a dispenser for injecting a viscous material, especially, an edible viscous material such as mayonnaise, cream or the like at a constant rate after it is once stored in the dispenser.
BACKGROUND ART
A dispenser for injecting a certain material such as a caulking agent or the like by actuating a trigger to squeeze a storing portion after it is once stored in the storing portion, in order to fill gaps or cracks arising inside/outside of a building with the foregoing material has been hitherto used (refer to an official gazette of, e.g., Japanese Patent Laid-Open Publication NO. 51-115718).
Trials have been made for practically employing a dispenser of the foregoing type as a cooking instrument for the purpose of injecting an edible viscous material such as mayonnaise, cream or the like. In recent years, especially, when mayonnaise is distributed over a number of dishes each having salad or the like placed thereon in a restaurant or the like, a dispenser including a cartridge molded of a thin sheet of synthetic resin by employing a blow molding process in consideration of easy exchanging of the present viscous material with other type of viscous material is increasingly employed as a cooking instrument. This type of dispenser is practically used by squeezing the cartridge with an operator's hand after the cartridge is once filled with the viscous material.
However, with respect to the cartridge having a small thickness as mentioned above, when the inner diameter of a storing portion for holding the cartridge is dimensioned to be equal to the outer diameter of an extrusion plate, there arise malfunctions that a bottom of the cartridge is infolded between the extrusion plate and the inner wall surface of the storing portion, resulting in the extrusion plate failing to be displaced further in the forward direction, and moreover, a part of the viscous material remains in the infolded Dart of the cartridge, resulting in the viscous material failing to be completely injected from the cartridge.
Even in case that no infolding occurs with the cartridge, it is observed that the outer peripheral surface of the cartridge comes in close contact with the inner wall surface of the storing portion with the result that the extrusion plate is hardly displaced in the squeezing direction.
To solve these problems, a proposal has been made with respect to a dispenser as disclosed in an official gazette of, e.g., Japanese Utility model Publication NO. 64-1270 wherein a container having a viscous material contained therein is received in an outer bag adapted to be slidably displaced so that the container can smoothly be compressed via the outer bag. However, this proposal is not practically employed due to an expensive cost because the container is produced by way of complicated steps, and moreover, it is a disposable container.
In addition, it is undesirably necessary from the viewpoint of structure that the dispenser is actuated with a large magnitude of actuating force. Since a viscous material contained in the container is not injected at a constant rate, there arises another malfunction that the viscous material can not exactly be injected through an injecting hole at a constant rate with the dispenser. Further, there appear problems that the injected viscous material is not sharply cut off from the container, and a part of the viscous material remains still in the vicinity of an injection port or the injection port is unsanitarily clogged with the remaining viscous material.
The present invention has been made in consideration of the foregoing background and its object resides in providing a dispenser for injecting a viscous material wherein an extrusion plate is smoothly displaced without incorrect operation of the dispenser due to infolding of a cartridge, and moreover, the dispenser can easily be handled with an operator's hand.
Here, a purport of the present invention consists in a dispenser employable as a cooking instrument. However, due to the fact that the foregoing
