商品が利用されている。2. Description of the Related Art Since a tennis ball, which is a general pressure body, has an internal pressure applied to the ball, the air inside the ball permeates the material forming the shell of the ball with the passage of time under atmospheric pressure. There is a problem that elasticity decreases and impetus deteriorates. Therefore, conventionally, a pressure-enclosed type product is used in which two to four tennis balls are placed in a steel can having a bottomed cylindrical shape, and then the can is sealed while an air pressure equivalent to the internal pressure of the ball is applied. .

Next, the open end of the inner bag is heat-sealed by heat fusion in a state where the pressurizing body is filled, so that the inside of the inner bag is in a completely sealed and gas-impermeable state. By loading the inner bag filled with the pressurizing body into the outer bag and engaging the outer bag with the outer bag, the inner bag is corrected by the outer bag so as not to expand beyond the inner diameter of the outer bag. By injecting compressed air from the pressurizing valve, the inner bag swells, the outer peripheral surface of the inner bag and the inner peripheral surface of the outer bag are in surface contact with each other, and a force is evenly applied to the outer bag. On the other hand, since the pressure difference between the internal pressure and the external pressure of the pressurizing body becomes small, the air in the pressurizing body is unlikely to leak. Also, when taking out the pressure body,
After operating the pressure valve to remove air, the inner bag is taken out from the outer bag, and the inner bag is crushed with a cutter or the like.

I got 20 balls. After that, the open portion of the inner bag was heat-sealed, then loaded into the outer bag, covered with an outer lid, and chucked with a surface fastener. After that, high-pressure air was injected from the pressure valve that popped out at the bottom of the outer bag to increase the inner pressure of the inner bag, and the pressure inside the inner bag was 0.4 kg / cm 2 (pressure inside the ball was approximately 1.9 kg / cm 2 (Breakdown: nitrogen gas 1.7 kg / cm 2 , oxygen gas
0.2kg / cm 2 )). The performance of the container was measured based on the test method shown below. (1) Pressure resistance test A pressure of 0.8 kg / cm 2 was applied to the inner bag of the container, and the tightness and pressure drop of the container after 48 hours were measured. Result: The container was not destroyed after 48 hours,
No pressure drop was observed in the inner bag. (2) Drop Test The state of the container was examined by dropping the container filled with the ball from a height of 2.5 m twice each vertically and horizontally. Result: No abnormality was found. (3) Destruction test In order to investigate abnormalities due to the external pressure of the container, the container was fixed at a depth of 10 m and a water pressure test was performed to see the condition of the container after 48 hours. Result: No abnormality was found. (4) Gas Permeation Test of Tennis Balls with Time A tennis ball with an internal pressure of 1.9 kg / cm 2 and a gas permeation rate of 70 cc / m 2 · day · atm was stored in the atmosphere and put in a container according to the present invention. A comparison was made with a case in which an inner pressure of 0.4 kg / cm 2 was applied to an inner bag having a volume of about 30,000 cc. The results are shown in Table 5.
