FIG. 2 is a vertical sectional side view showing the internal construction of the tape container shown in FIG. 1.

' container shown in FIG. 1.

FIG. 4 is a top planar view of the container shown in FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIG. 1, the reference numeral 1 indicates a body portion of a tape container embodying the present invention. It is provided at the center thereof with a cylindrically protruding socket 2 having an opening 211 on the top thereof. The socket 2 is shaped to receive the central hole of the core of the tape reel put in a container. On the inner periphery of the opening 2a of the socket 2 is provided a stopper ring 3 as shown in FIG. 2.

The reference numeral 4 indicates a cover portion to be mated with the body portion 1. The cover portion 4 is provided with a rotary locker 5 at the center thereof in a recess 6 formed thereon as shown in FIG. 2. Referring to FIG. 2, the recess 6 has a through hole 6a at the center thereof defined by a downwardly extending cylindrical portion 6b of the recess 6. The lower portion of the cylindrical portion 6b is inserted into the opening 2a of the socket 2 of the body portion as shown in FIG. 2. The rotary locker 5 is engaged in the lower portion 6b of the recess and inserted into the opening 2a together with the lower cylindrical portion 6b. The rotary locker 5 has a conical hollow upper portion 5a fitted on the inside of the recess6 and is provided with a hole 8 at a position facing a latch hole 7 formed on the inside surface of the recess 6 of the cover portion 4.

The reference numeral 9 indicates a latch plate slidably mounted on the rotary locker 5. As shown in FIG. 3, a mounting member 9a is mounted on the bottom surface of the latch plate 9, and a pawl 10 is mounted on one end of the mounting member 9a. The pawl 10 is normally urged radially outward to be put into the latch hole 7 through the hole 8 of the rotary locker 5 by means of a spring 11. The mechanics of this operation will be explained in detail later in connection with FIG. 3. Returning to FIG. 2, on the bottom surface of the mounting member 9a at the center thereof is provided an arm support 12a extending longitudinally and an arm 12 extending laterally through the arm support 120. The arm 12 is spaced from the bottom surface of the latch plate 9 and is engaged with a U-shaped twofork coupling member 15 which in turn is engaged with a guide rod 13 extending vertically in the container at the center thereof. The U-shaped two-fork coupling member 15 has an upper fork portion 15a and a lower fork portion 15b. The upper fork portion 15a is engaged with said arm 12 of the mounting member 9a with said arm support 12a fitted therewith. The lower fork portion 15b is engaged with the upper end of the guide rod 13 so as to be rotated together with the guide rod 13. The guide rod 13 is provided at the lower end thereof with a finger plate 14 which is pressed on the stopper ring 3 at the time of locking. By the coupling member 15 and the mounting member 9a the latch plate 9 is connected with the finger plate 14 so that the finger plate 14 is rotated together with the latch plate 9 As shown in FIG. 3, in detail, the pawl 10 and the arm support 12a are fixed to a mounting member 9a which in turn is mounted on the bottom surface of the latch plate 9. An end of the mounting member 9a opposite to the end at which said pawl is mounted is provided with a spring holder 11a. The spring 11 is mounted to the spring holder and urges the mounting member 9a, and accordingly the latch plate 9, in the direction to put the pawl 10 into the latch hole 7 of the cover portion 4. By sliding the latch plate 9 in the longitudinal direction, the arm 12 slides in the fork portion a of the coupling member 15.

As shown in FIG. 4, the cover portion 4 is provided with three latch holes, an OPEN latch hole 7A, a CLOSED latch hole 7B, and a LOCKED latch hole 7C. The OPEN latch hole 7A has a ramp on one side to slip out the pawl 10, the CLOSED latch hole 7B has ramps on both sides thereof and is located on the ramp side of the OPEN latch hole 7A, and the LOCKED latch hole 7C, located on the opposite side of the CLOSED latch hole 78 from the OPENlatch hole 7A, has no ramp.

As shown in P16. 2, the finger plate 14 abuts on the cylindrical portion 6b of the recess 6 and the stopper ring 3 when the latch plate 9 is in the LOCK position. When the latch plate 9 is in the OPEN position, the finger plate 14 is aligned with the opening 2a of the socket 2 and is therefore removable from the body portion 1. When the latch plate 9 is not in the OPEN position, the finger plate 14 is not removable from the socket 2.

Now, in operation of the above described tape container, a reel on which a video tape or the like is wound is put into the body portion 1 with the cover portion 4 removed as shown in FIG. 1. The core hole of the reel is engaged with the socket 2 of the body portion 1 to prevent vibration of the tape reel in the container during transportation. Then, the latch plate 9 is rotated to the OPEN position 7A to bring the finger plate 14 to the position to be inserted into the opening 2a of the socket 2 so that the cover portion 4 may be brought into engagement with the body portion 1, and the cover portion 4 is placed over the body portion 1.

Then, in order to retain the cover portion 4 on the body portion 1, the latch plate 9 is rotated to the position where the pawl l0-comes to the CLOSED position 78. As the latch plate 9 is manually rotated, the finger plate 14 rotates in the socket 2 and rises on the stopper ring 3 in order to prevent the removal of the cover portion 4 from the body portion 1.

Although the cover portion 4 may not be removed from the body portion 1 with the latch plate 9 turned to the CLOSED position 7B, there is a ramp in the latch hole 78 and accordingly there is a possibility of removal of the pawl 10 from the latch hole 78. The latch plate 9 is required to be locked more firmly in case of transportation or the like.

ln order to lock the latch plate 9 more firmly, the latch plate 9 is rotated further to the LOCKED position 7C. The latch plate 9 can be easily rotated from the CLOSED position 78 rising on the ramp. At the LOCKED position, the pawl 10 fixed to the end of the latch plate 9 enters into the latch hole 7C by the spring force of the compression spring 11, and the latch plate 9 is firmly locked in the LOCKED position. The finger plate 14 also rotates together with the latch plate 9 and comes to the position where the plate 14 rides on the socket 2 and the stopper ring 3. The finger plate 14 is pressed on the stopper ring 3 at this position and firmly locked in place. Further, since the pawl 10 is engaged with the latch hole 7C without a ramp, the latch plate 9 never slips out of the hole, and the cover portion 4 does not separate from the body portion 1.

In order to open the cover by removing the cover portion 4 from the body portion 1 of the container, the latch plate 9 is slided against the spring force to pull the pawl 10 out of the latch hole 7C. Thus, the pawl 10 is removed from the hole 7C and the rotary locker 5 is made rotatable in the recess 6. By rotating the latch plate 9 up to the position where the pawl 10 comes to the OPEN position 7A, the finger plate 14 is made removable from the body portion 1 of the container. After the finger plate 14 is brought to the position where it is removable, the cover portion 4 is pulled upward to separate the cover portion 4 from the body portion 1. Thus, the cover is opened.

While the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof.
