Abstract

A container includes a cover 20 secured on a base 60 for receiving an insert 30, and a knob 51 slidably received in the base. A latch 52 is slidably engaged in the base 60 and is biased by a sprig 53 to secure the insert in place by engaging a notch 33. The knob 51 includes a tapered surface 511 for disengaging the latch 52 from the insert 30 on pressing the knob 51. A spring 40 biases the insert 30 outward of the base 60 and is secured to the base 60 by a retainer 64 and pin 65.

Description

2341594 CONTAINER FOR CASSETTE OR THE LIKE The invention relates to a

container for cassette.

Typical disc containers comprise a base for storing disc and a cover pivotally coupled to the base for covering the disc. The cover includes a f ront button for controlling the outward movement of the base. However, the spring for biasing the base outward of the container may not be stably retained in place, and the latch device may not be effectively operated.

It is accordingly an object of the present invention to provide an improved container that may be easily opened and closed.

According to the present invention there is provided a container for tape cassette comprising:- a) a base including a front portion having a first corner area and including a rear portion having a rear wall, the base including a chamber and a channel provided in the first corner area of the base, b) an insert slidably engaged in the base, the insert including a notch, c) a cover secured on the base for retaining the insert in the base, d) a latch slidably engaged in the channel of the base for engaging with the notch of the insert and for retaining the insert in place relative to the base, the latch including an extension extended upward, e) means for biasing the latch to engage with the notch of the insert and for retaining the insert in place relative to the base, f) a knob slidably engaged in the chamber and having a tapered surface for engaging with the extension of the latch and for moving the latch away from the insert against the latch biasing means and for disengaging the latch from the notch of the insert when the knob is depressed inward of the chamber, g) a spring engaged between the rear wall of the base and the insert for biasing the insert forward and outward of the base, the spring including a rear segment, and h) means for securing the rear segment of the spring to the base. The insert is allowed to be biased forward and outward of the base by the spring when the latch is disengaged from the notch of the insert by the knob.

The base includes a retainer and a pin formed in the rear portion of the base and close to the rear wall of the base, the rear segment of the spring includes an end portion for engaging with the retainer and includes a bent portion engaged with the pin, for allowing the rear segment of the spring to be stably secured in place to the base.

A bar is further provided and formed in the rear portion of the base and close to the rear wall of the base and close to the pin, the bent portion of the rear 3 segment of the spring is engaged between the pin and the bar for allowing the rear segment of the spring to be stably secured in place to the base. In the drawings:05 FIG. 1 is an exploded view of a container; FIG. 2 is a top perspective view of the container, in which the cover is removed and the insert is moved outward of the base for showing the interior structure of the container; 10 FIG. 3 is a cross sectional view taken along lines 3-3 of FIG. 5; FIG. 4 is a cross sectional view similar to FIG. 3, illustrating the operation of the container; FIGS. 5 and 6 are perspective views illustrating the operation of the container, in which the container is rotated for 180 degrees relative to FIG. 1; and FIG. 7 is a perspective view illustrating the operation of the container.

Referring to FIGS. 1-4, a container comprises a base 60 including four projections 62 provided on the four corner areas and including a rear portion having a wall 602 extended upward. A cover 20 includes four holes 21 for receiving the projections 62 and for allowing the cover 20 to be easily secured to the base 60. The base 60 includes a retainer 64 and a pin 65 and a bar 66 formed in the rear portion close to the wall 602 for engaging with and for securing the rear segment of a spring 40 in place. The cover 20 includes four depressions 22 formed in top of the four corners. The base 60 includes four bulges 63 extended downward from the four corners for engaging with the depressions 22 of the cover 20 and for allowing two or more containers to be stably stacked with each other (FIG. 7). The base includes two front corners each having a rib 67 and a protrusion 68 provided thereon respectively.

The base 60 includes a chamber 61 formed and provided on one of the front corners of the base 60 for slidably receiving a knob 51 which includes a tapered surface 511. A channel 611 is formed and provided behind the chamber 61. A latch 52 is slidably engaged in the channel 611 and includes an extension 521 extended upward for engaging with the tapered surface 511. A spring 53 is engaged with the knob 51 for biasing the knob 51 outward of the chamber 61 and inward of the base along a longitudinal path, and for biasing the extension 521 of the latch 52 to engage with the tapered surface 511 of the knob 51 and to move the knob 51 outward of the base 60 by the engagement of the extension 521 with the tapered surface 511.

An insert 30 is slidably engaged between the base and the cover 20 and includes a flexible disc retaining hub 302 provided in the center portion. The cover 20 may stably retain the insert 30 in the base 60. The insert 30 includes a seat 34 for receiving the other end or the bent end 46 of the spring 40 which is engaged between the insert 30 and the wall 602 for biasing the insert 30 outward of the base 60. The insert 30 includes a shoulder 32 formed in one of the side portions for slidably engaging with the rib 67 of the base 60 and for guiding the sliding movement of the insert 30 relative to the base 60. The insert 30 includes a stop 31 for engaging with the protrusion 68 and for preventing the insert 30 from disengaging from the container. The insert 30 includes a notch 33 for receiving the latch 52 which may-retain the insert 30 in the base 60.

The rear segment of the spring 40 includes an end portion engaged with the retainer 64 and includes the bent portion 41 for engaging with the pin 65 and the bar 66 and for allowing the rear segment of the spring 40 to be stably retained in place to the base 60. The spring 40 includes a middle segment 43 formed between the bent portion 41 and the other bent portion 44. It is preferable that a tapered portion 42 is formed between the middle segment 43 and the bent portion 41 for increasing the resilience of the spring 40 (FIGS. 3, 4). The spring 40 includes an outer segment 45 having the bent end 46 for engaging with the seat 34 of the insert 30, and includes a Z-shaped configuration (FIGS. 1, 3) for allowing the spring 40 to includes an excellent resilience.

6 In operation, as shown in FIGS. 2-6, when the insert 30 is moved inward of the base 60, the latch 52 may be biased by the spring 53 to engage with the notch 33 of the insert 30 for retaining the insert 30 in the base 60 (FIG. 3). When the knob 51 is depressed inward of the cover 20, the tapered surface 511 of the knob 51 may move the latch 52 away f rom the insert 30 against the spring 53 for disengaging the latch 52 from the notch 33 of the insert 30 and for allowing the insert 30 to be moved outward of the base 60 by the spring 40, such that the container may be easily opened with only one hand.

As shown in FIG. 7, the knob 51 may be easily depressed by the user when the containers are superposed with each other such that the insert 30 of the middle containers may also be easily opened.

Accordingly, the container includes an insert which may be easily opened and operated with only one hand even when a number of containers are superposed with each other. In addition, the knob 51 is facing forward and may thus be prevented from being depressed inward of the cover 20 by the other containers when a number of containers are stacked or superposed with each other. The latch may be effectively operated and biased to move along a longitudinal path by the spring 53.
