- Tennis balls are manufactured to close specifications in order to have a uniform product for use anywhere in the world.
- One of these specifications is that the ball must have a bounce between 53 inches and 58 inches when dropped on a concrete surface from 100 inches in height.
- tennis balls are made with a relatively thin wall of elastomeric material, covered on the out side with a felt fuzz, and filled with gas (such as air) under pressure.
- the halls are usually packaged in groups of three in a container having sufficient pressure to substantially equalize the pressure in the balls. This method of packaging maintains the physical characteristic of the balls until the container is opened.

Tennis balls are manufactured to close specifications in order to have a uniform product for use anywhere in the world. One of these specifications is that the ball must have a bounce between 53 inches and 58 inches when dropped on a concrete surface from 100 inches in height. In order to meet this specification and other specifications, tennis balls are made with a relatively thin wall of elastomeric material, covered on the out side with a felt fuzz, and filled with gas (such as air) under pressure. The halls are usually packaged in groups of three in a container having sufficient pressure to substantially equalize the pressure in the balls. This method of packaging maintains the physical characteristic of the balls until the container is opened. At this time the fresh balls begin to age in a primary way, that being the gradual escape of internal gas through the thin wall of the ball at all times and also the acceleration of this escape when the ball is hit with a racket.
The importance of having tennis balls with uniform physical characteristics must not be minimized. Those who are serious tennis players, either the relatively few competitors in tournaments or the many more competitors in recreational play, appreciate the feel of striking a good ball with a racket. It is well known that old defective balls will not go where they are hit and that in trying to compensate for the deficiencies in an old ball, a player will often ruin a good stroke that has been developed with much practice. Some of the best players would rather not play at all rather than play with defective balls.
Once the tennis ball pressurized container which is in common use has been opened, the balls which are not being used and are located in that container begin their deterioration. Also, once a ball has been used, it would be desirable to relocate the used ball in a pressurized atmosphere in order to decrease the balls deterioration.
In the past, there have been several types of containers which have been proposed for such use. However, such previously known containers are complex in construction and therefore costly to manufacture and also require to be connected with a source of pressurized gas once the container is reclosed. As a result, such containers have not achieved any significant commercial success and as of the present day, no repressurizing type of container is known to be employed which repressurizes by interconnecting members.
The pressurization which is required in the containers in which the balls are sold is approximately 13 pounds per square inch. This pressure is not so significantly high as to require a separate pressurizing apparatus to be connected with the container to repressurize the container. It is one object of this invention to employ the use of a pressurizing means incorporated with the container which can be readily applied manually.
SUMMARY OF THE INVENTION The container of this invention provides for a body portion and a cap portion. Once the cap portion is initially inserted upon the body portion, an air-tight connection is established therebetween through an O-ring seal mounted upon the body, closing off the interior of the body portion of the container to the ambient. Means are provided between the cap and the body portion such as a threading arrangement which permits the cap to be tightened upon the body. As a result. the volume of the space within the body portion of the container is decreased. This decreasing of the volume causes a compression of the gas, which is normally air, within the body. The arrangement between the cap and the body is such so that with the cap completely tightened upon the body, the pressurization of the gas within the body will be approximately [3 pounds per square inch. Therefore, the tennis balls which are to be located within the container will again be placed within a pressurized environment. Means are provided between the cap and body to maintain and prevent leakage of the established pressurized environment, such means being described in the Abstract of the Disclo sure and reference is to be had thereto,
BRIEF DESCRIPTION OF THE DRAWING FIG. I is an isometric view of the container of this invention showing the cap disassociated from the body;
FIG. 2 is a side view of the container of this invention showing the cap completely closed about the body;
FIG. 3 is a cross-sectional view of the container of this invention taken along line 33 of FIG. 2; and
FIG. 4 is an enlarged cross-sectional view of a portion of FIG, 3 showing the means to maintain the pressurization of the container of this invention.
DETAILED DESCRIPTION OF THE SHOWN EMBODIMENT Referring particularly to the drawing, there is shown in FIG. 1 the container 10 ofthis invention which is basically composed of a cap 12 and a body I4. The body 14 includes an interior chamber 16 which is adapted to receive a plurality (normally three in number) of tennis balls 18. However, it is to be understood that although this invention is described in reference to the use of tennis balls, it is considered that the apparatus of this invention may be employed for other types of game balls or to pressurize other types of contents. The device of this invention could be readily used for handballs and racquet balls with the container body and cap being scaled to provide the required pressure.
The cap 12 also includes an interior chamber 20. The size of chamber 20 is just slightly larger than the body I4 so that body 14 can be telescopingly received in chamber 20 establishing a close interfit between body 14 and cap I2. An O-ring seal 22 is mounted within an annular groove 23 formed in body 14 adjacent the inner end 25. Seal 22 is formed of a conventional resilierit material such as rubber. The purpose of the seal 22 is to insure that an airtight connection is established between the cap I2 and the body 14 when the cap 12 is inserted upon the body 14.
Located within chamber 20 adjacent the closed end of cap 12 is an inwardly extending annular flange 29. The function of flange 29 will be explained further on in the specification.
Secured to the cap 12 within the chamber 20 is an internal thread 24. Fixedly mounted upon the body 14 is a thread 26. Threads 24 and 26 cooperate together to move body 14 within cap 12. The inner end of thread 24 terminates in a stop 27. With thread 26 in contact with stop 27, the inner end 25 is just slightly spaced from the closed end of cap 12 forming a gap therebetween. In this position the O-ring seal 22 is tightly pressed against flange 29 and actually deforms slightly (approximately nine thousandths of an inch). This pro duces an extremely air-tight connection between cap 12 and body 14 and prevents leakage of the pressurized air from chamber 20. In essence. the cooperation between the flange 29 and the seal 22 is a secondary seal with the primary seal being the O-ring seal 22 in tight contact with the wall of section 30. As illustrated by the dotted line position of the groove 23 and O-ring seal 22 in FIG. 4, the O-ring seal 22 seals against the wall section 30 as it moves to its upper full line position in FIG. 4.
The operation of the container of this invention is as follows: A person grasps both the body 14 and the cap 12 and causes a turning movement to occur there between by the application of manual force. Turning of the body [4 in respect to the cap 12 is facilitated by gripping area 15 on body 14 and gripping area 13 on cap 12. This causes the thread 24 to be moved along the thread 26 until the cap 12 can be disassociated from the body 14. It is to be noted that the depressuration of the chamber 16 is accomplished gradually and no ejecting of the cap 12 is caused. Once the cap 12 has been removed from the open end of body 14, the ball (or balls) 18 which is stored within the chamber 20 can be readily removed.
Let it be assumed that only a single ball 18 has been removed from the chamber 20. The operator then relo cates the cap 12 upon the body portion 14 so that thread 24 becomes coupled with the thread 26. ln this initial position an air-tight seal is established between the O-ring 22 and the smaller diameter section of the cap [2. It is to be noted that the diameter of the thread 24 is equal to or greater than the diameter of the section 20 in order to permit passage of the O ring 22 past the thread 24. With the air-tight connection being initially established between the cap 12 and the body 14 as the cap 12 is rotated about the body 14, a recompression occurs within the chamber 16. The longitudi nal movement of the cap 12 upon the body [4 is preselected so that the compression of the gas within the chamber 16 is to the value of approximately 13 pounds per square inch with three balls located in the chamber 16. Therefore. the balls which are not in use and are being retained within the chamber 16 are not caused to deteriorate but are stored in a satisfactory pressurized environment. New tennis balls are pressurized internally to a value of about 13 psi It is to be understood that with one or two balls removed from chamber 16, a pressurization of less than the initial 13 psi would resultv However, a partial pres surization is better than no pressurization.
At the time the operator decides to relocate the ball that is being used within the container 10, the container 10 is opened, the ball inserted in the container 10 and then closed. This causes a pressurization of the gas within chamber 16 and prevents the ball that was used from deteriorating as well as the unused balls.
