Embodiment Construction

[0030]While this invention is susceptible of embodiment in many different forms, there is shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.

[0031]FIGS. 1-4 show a hand operated pump 10 having a plunger 12, a barrel 14, a cap 16 and an adapter 18. The pump 10 has a proximal end 20 and a distal end 22. The hand operated pump 10 is useful in evacuating excess air from a vacuum storage container, such as those shown in FIGS. 10 and 11, to increase the shelf life of food within the container. FIG. 2 shows the hand operated pump 10 in a disassembled state. The plunger 12 has a handle 30 at a proximal end, a piston 32 at a distal end and a stem 39 therebetween. The piston 32 has annular recess 33 about a circumferential portion thereof that ...
