Tamper resistant wide mouth package with dynamic seal

A tamper resistant package comprising:

• a container having a side wall defining an open end, a closed end wall attached to said side wall, and a radially extending sealing surface formed on said side wall at said open end;
• a closure formed of a flexible material having a depending annular skirt adapted to securely fit onto said open end of said container, and a radially extending inner sealing surface for engaging said radially extending sealing surface on said container to form a first static seal;
• an outwardly extending annular ridge formed on said container having an upwardly and outwardly facing chamfer;
• an inwardly extending annular ridge formed on said skirt having a downwardly and outwardly facing chamfer, said ridges adapted to engage placing said container and closure under tension to secure said closure on said container and said chamfers forming a second static seal;
• and
• an outwardly facing annular sealing surface formed on said side wall and a lip formed on said closure for engaging said outwardly facing sealing surface to form a dynamic seal, and whereby an attempt to disengage said closure from said container will cause a visual change to at least one of said container and said closure which damage can be seen by observing the package from said open end.

A tamper resistant package comprising:

• a container having a side wall defining an open end, a closed end wall attached to said side wall, said side wall including an inner wall and an outer wall at said open end, and said outer wall forming a generally U-shaped channel;
• a closure formed of a flexible material having a depending annular skirt adapted to securely fit into said generally U-shaped channel to close said open end of said container;
• a first seal formed from abutting a radially extending sealing surface on said inner wall at said open end and a radially extending inner sealing surface formed on said closure;
• a second seal formed by abutting a radially outwardly extending ridge formed on an outer surface of said inner wall and a radially inwardly extending ridge formed on said depending skirt;
• a third seal formed by abutting an inwardly facing annular sealing surface formed on said outer wall and an outwardly facing annular sealing surface formed on said depending skirt;
• and
• a fourth seal formed by abutting an outwardly facing annular sealing surface on said inner wall and a generally inwardly extending annular lip formed on an inner surface of said closure, said first, second and third seals being static seals and said fourth seal being dynamic seal.
