## Abstract

A container includes a cover secured on a base for receiving an insert. The base has a block formed in the real side portion for receiving a spring and a button. The spring includes a protrusion extended inward of the base for engaging with the insert and for retaining the insert in the base. The insert may be moved outward of the base when the button is depressed inward of the cover such that the container may be easily operated with only one hand. The button can be prevented from being depressed inward of the cover inadvertently. The button includes a knob for depression the button when a number of containers are stacked with each other.

## Claims

### Claim 1

A container comprising:
a base including a rear side portion having a block formed in said rear side portion of said base, said block including a cavity and a slit and a slot,
a cover engaged on said base, said cover including a rear side portion having a recess and an orifice and a channel formed in said rear side portion of said cover, said channel being communicating with said orifice,
a spring and a button engaged in said cavity of said block, said spring including a protrusion engaged in said slit and extended inward of said base, said button being engaged in said orifice of said cover and engaged in said recess of said cover, said button including an extension slidably engaged in said slot of said block and in said channel of said cover and including a knob secured to said extension for depression said button,
an insert slidably engaged in said base, said insert including a catch for engaging with said protrusion of said spring and for allowing said protrusion to retain said insert in said base, and
means for biasing said insert outward of said base,
said catch of said insert being caused to engage with said protrusion of said spring when said insert is moved inward of said base, for allowing said protrusion to retain said insert in said base, said biasing means moving said insert outward of said base when said catch is disengaged from said protrusion of said spring and when said button is depressed inward of said cover, and said button being engaged in said recess of said cover for preventing said button from being depressed inward of said cover inadvertently.

### Claim 2

A container comprising:
a base including a rear side portion having a block formed in said rear side portion of said base, said block including a cavity and a slit and a slot, said base including a front portion having a pair of flanges extended upward and including a rear portion having a wall extended upward, said flanges and said wall and said block each including a projection,
a cover including four holes for engaging with said projections of said base and for allowing said cover to be secured to said base, said cover including a rear side portion having a recess and an orifice and a channel formed in said rear side portion of said cover, said channel being communicating with said orifice, said cover including a front portion having a pair of ears extended downward,
a spring and a button engaged in said cavity of said block, said spring including a protrusion engaged in said slit and extended inward of said base, said button being engaged in said orifice of said cover and engaged in said recess of said cover, said button including an extension slidably engaged in said slot of said block and in said channel of said cover and including a knob secured to said extension for depression said button,
an insert slidably engaged in said base, said insert including a catch for engaging with said protrusion of said spring and for allowing said protrusion to retain said insert in said base, said insert including two side portions each having a shoulder formed therein for engaging with said ears of said cover and for guiding an outward movement of said insert relative to said cover, and
means for biasing said insert outward of said base,
said catch of said insert being caused to engage with said protrusion of said spring when said insert is moved inward of said base, for allowing said protrusion to retain said insert in said base, said biasing means moving said insert outward of said base when said catch is disengaged from said protrusion of said spring and when said button is depressed inward of said cover, and said button being engaged in said recess of said cover for preventing said button from being depressed inward of said cover inadvertently.
