This invention relates to a sealing mechanism in a container made of plastic.
BACKGROUND
Containers available in the market do not fulfil the normal requirements of household in terms of air-tightness of containers for storing items like biscuits and other food items. After some time contents of the container get either contaminated or spoiled due to moisture.
The object of the invention is to provide a sealing mechanism between the lid and the container to obviate the above drawback.
To achieve the said objective this invention provides sealing mechanism in a
container made of plastic comprising:
a container having a rib and a lip portion on the top of said container,
a lid to be snugly fitted on said lip portion of said container characterized in that the outer wall and the inner wall of the lip portion makes 81-85° and 82-88° angles with the horizontal axis and the radius of the lip at the top corners from inner to outer edge of the lip vary from 0.4-0.9 mm and 0.9-1.6 mm such that the thickness of the lip increases with the height from the rib for providing snugly fitting to said lid
The said lip portion at the top has flat surface 0.7-1.3 mm
The said lid comprising:
a female contour on the periphery of said lid to be snugly fitted on said lip portion of the container

the outer wall of said female contour makes 102.29-106.29° angle and inner wall makes 92-98° angle and the radius at the bottom corners of said lip contour vary from 0.9-1.4 mm on outer side and 0.4-0.8 mm on the inner side such that the thickness of the female contour increases with the height of the lip and snugly fits in on the lip of the container
The said female contour portion at the top has a flat surface 1.0-1.5 mm The container is made of polypropylene.
The invention will now be described with reference to the accompanying drawings
Figure 1 shows the container, according to this invention.
Figure 2 shows the lid, which is to be fitted on the top of the container according to this invention.
