6 Claims. c1. 813.4)
This invention relates to a device for removing caps from containers and more particularly to a device for removing a closure from a container in which radioactive material is stored or shipped.
In the handling of radioactive material packed in conventional screw threaded containers with caps, it is necessary that precautions be taken to protect the person handling the said containers. This problem is especially acute during the operation of removing the cap from the container prior to removal of a portion or all of the radioactive material from the container. It is therefore desirable to have an opener, which in addition to opening the container rapidly and conveniently, will at the same time protect the operator from exposure to the radioactive material.
It is therefore an object of this invention to provide an improved closure removing device for a container of radioactive material, which is easy to handle.
It is also an object of this invention to provide an improved closure removing device for containers in which radioactive material is stored or shipped which will protect the operator from exposure to radiation.
It is still another object of this invention to provide a device for opening containers in which radioactive material i kept which will facilitate removal of a screw threaded closure of the container more rapidly and conveniently.
Other objects of the invention will be apparent from the detailed description and claims to follow when taken in conjunction with the accompanying drawings.
In the drawing:
Figure l is a side elevational view of the closure removing device engaging the closure of a container.
Figure 2 is a partial vertical sectional view of the closure removing device shown in Figure 1.
Figure 3 is a lower end view of the closure removing device of Figure 1 without the container associated therewith.
The opener shown in the drawing comprises a handle comprised of an elongated cylindrical section 11 which is made of a rigid material, preferably plastic, such as methyl methacrylate. Disposed at the upper end of the cylindrical section 11 and preferably formed of the same material as section 11 is a knob 12, which is axially bored a short distance inwardly to accommodate and seat therein the end of the section 11. Disposed at the lower end of the cylindrical section 11 and preferably comprised of the same material is a cylindrical block 13 which is axially bored a short distance inwardly to form a recess therein to accommodate and hold securely the lower end of section 11. Positioned immediately below the lower end of section 11 and seated in block 13 is a small lead disc 14 having a diameter equal to the diameter of the section 11. A large diameer lead disc 15 with an axial passage extending therethrough of a diameter substantially that of the cylindrical section 11 is transversely positioned about the section 11 and is held securely against the upper surface of the block 13 by a disc 16 which has an axial passage to accommodate section 11 and is preferably formed of the same rigid plastic material as the handle 10. The knob 12, block 13 and disc 16 are also preferably solvent sealed to the cylindrical section 11 to provide a secure assembly.
Extending inwardly from the lower surface of block 13 is a stepped cylindrical recessed compartment 17 formed by an inner cylindrical section 18 and an outer larger diameter cylindrical section 19. Compartment 17 serves to accommodate a flexible closure gripping member (as best illustrated in Figure 2). The gripping member 20 is comprised preferably of a cylindrical solid flexible rubber base section 21 and an outwardly extending flexible gripping wall 22 which preferably projects slightly beyond the end of the block 16.
The flexible closure gripping member 20 is positioned in compartment 17 by slightly moistening to lubricate the said gripping member at the time of insertion. Also, at the time of insertion, the base of the gripping member 20 is pierced through with a needle to allow for the escape of fluid pressure which forms behind the gripper at the time of insertion. By employing this procedure, the gripper 20 is held securely in compartment 17 by the friction and the resulting vacuum which is formed when any pulling force is exerted on the gripper when the opener is put into operation.
In operation, the flexible closure gripping member 20 is placed directly over and in axial alignment with the container cap 23 which threadably engages the threads 24 on the neck 25 of the container 26 the base of which is held by mechanical means against rotary movement. A downward force on the handle 10 causes the gripping member 20 to engage the container cap 23, as best shown in Figure 2 of the drawing. The handle 10 is then turned in the direction required to back off the cap .23 from the container. To replace the cap, the cap held by the gripping member 20 is positioned over the threaded neck of the container 24 and the handle 10 turned in a direction to screw the cap 23 onto the container 26, the handle 10 is given a slight pull in an axial direction opposite said container and the cap 23 is thereby released by the gripping member 20. During this operation it will be noted that the operators hand is completely protected from any possible radiation by the large diameter disc 15 and the small diameter disc 14 which together form a complete plane of protection.
It should be understood that while all of the parts of the novel opener are described as being comprised of a rigid plastic material, with the exception of the two lead discs and the rubber gripper, other rigid materials such as wood, steel, brass, aluminum and similar machineable materials can be employed.
It should also be understood that the term rigid plastic material as employed herein is meant to include such materials as methyl methacrylate, styrene, polyvinylchloride, nylon, lucite and similar natural and synthetic materials.
While the flexible gripping device herein described is composed of rubber, it should be understood that the gripping device can be made of other flexible materials such as polyvinylchloride and similar natural and synthetic materials.
