7 Claims. (Cl. 222-82) The present invention relates to a closure device and relates, more particularly, to a rupturable closure device for use with a fire extinguisher. 7
An object of the present invention is to provide a rupturable closure device for a pressurized container such as a fire extinguisher, which upon operation will permit the contents of the container to be discharged rapidly and which can be made cheaply for use on containers of the throw-away type. Other objects andadvantages of the invention will be apparent and best understood from the following description and the accompanying drawings in which:
Fig. 1 is a side elevation of a pressurized container having a rupturable closure device embodying the invennon;
Fig. 2 is a vertical section view ofthe rupturable closure device illustrated in Fig. 1; f
Fig. 3 is a fragmentary view in section of a portion of the closure device illustrated in Fig. 2, but on an enlarged scale;
Fig. 4 is a fragmentaryview in section corresponding to Fig. 3, but with the parts shown in their positions after t operation of the device; 1 t
Fig. 5 is a side elevation in partial section of a part of the closure device illustrated in Fig. 2;
Fig. 6 is a fragmentary view in section of a portion of the part shown in Fig. 5, but on'an enlarged scale;
Fig. 7 is an end view as seen from the left of the part shown in Fig. 5, but on an enlarged scale; and
Fig. '8 is a fragmentary view in section of another part of the closure device illustrated in Fig. 2. p Referring to the drawings in detail, there is a container of the type commonly used for packaging and dispensing various commodities under pressure. In the case of a fire extinguisher, the container 10 may contain a dry powder, such as baking soda or other suitable fire extinguishing medium, and a suitable propellant, such as dichlorodifluoromethane (Freon-12).
The container 10 is provided with the customary closure cap 11 which is applied theretoin the usua'l manner. As shown in Fig. 2, the central portion of the closure cap is depressed and there is an opening thereinin which an elongated tubular shell or body' 12 is secured. Portions of the tubular body extend above and below the de pressed central portion 'of the closure .cap and the tubular body is sealed to the edges of the opening in the closure cap. The lower end of the'tubular body is closed by'a rupturable disc or diaphragm 13 with the upper end of the body being open. If desired, the tubular body or a portion thereof may be formed integrally with the closure cap for the container.
A plastic discharge cap 14 has a central opening 15 extending through it. The opening 15 is fitted over and communicates with the upper end of the tubular body which extends above the opening in the closure cap. The discharge cap 14 fits into the depressed portion of the closure cap and is normally held in place by frictional engagement with the tubular body and the closurecap.
ice
The discharge cap 14 is also provided with a discharge spout 16 which communicates with the central opening therein and through which the contents of the container will be discharged when the disc 13 is ruptured.
An operating member 17 extends into the tubular body and has a stem portion which extends through the opening in the discharge cap with the top thereof projecting beyond the topof the discharge cap to a position where it may be operated manually. The top of the operating member is threaded and an operating button 18 is attached thereto.
The lower end of'the operating or piercing member 17 carries an enlarged cutting head 19 which is positioned inside of the tubular body in opposing relation to the rupturable disc. In operation of the device, the cutting head is brought into engagement with the rupturable disc 13 by pressing down on the operating button 18 at the top end of the operating member and the disc is quickly severed from the tubular body. The opening 15 in the discharge cap is reduced in area at the top thereof and makes a close fit with the stem portion of the operating member at this point. This prevents discharge of the contents of the container through the top of the discharge cap and also prevents .the operating member from being removed from the discharge cap and the tubular body. However, it should be noted that the stem portion of the operating member is considerably smaller in diameter than the inner'dia'meter of the tubular body and does not interfere withthe discharge of the contents of the container through the tubular body.
Inorder to prevent the operating member from being depressed accidentally, a forkedclip 20 is located between t-he top of the discharge cap 14 and the bottom of the operating button 18. The clip 20 engages with ribs 21 on the top of the discharge cap and spaces the operating button from the cap a suflicient distance to prevent the cutting head from being brought into engagement with the rupturable disc 13. For operation of the device, the clip can be quickly removed.
As shown best in Figs. 6 and 7, the lower surface of the cutting head 19 is cut at an angle to the axis of the operating 'member' and has a sharp knife-like cutting edge 22 extending at an angle to the lower surface along a portion of its .outer edge. The lower surface of the cutting head is cut at an. angle of about 20 from a perpendicular to the axis of the operating member and the cutting edge is cut at an angle of about to the axis operation is completed.
of the operating member. The operating member may be formed ona standard coldheading machine with the angular surfaces on the lower surface of the cutting head being formed on a standard screw machine provided with a suitable cutter.
As shown best in Fig. 8, the lower end of the tubular body 12 is bevelled inwardly at an angle of about 30 to theaxis of the tubular body as indicated at 23. The lower end of the tubular body is joined to the bottom closure .disc 13 by a relatively thin membrane 24 which extends around the outer edges ,of the disc. The tubular body'rnay be formed on a standard eyelet machine.
Inoperatiomthe inwardly sloping portions 23 of the tubular body guide the cutting edge of the cutting head into engagement with the thin membrane 24 and permits the bottom disc to be ruptured thereby as the result of light finger pressure on the operating button. When the cutting head is moved down, the cutting edge engages with and ruptures the connection of the disc to lower end of the tubular body and the angular lower surface of the cutting head causes the cutting head to slide to one side under the lower end of the tubular body as the cutting In thisposition, the end of the tubular member engages with the rear of the enlarged cutting head, as shown in Fig. 4, and latches the operating member to the tubular member. This prevents the operating member and the discharge cap from being blown 01? of the closure cap under the force of the contents being discharged from the container.
If desired, asiphon tube 25 maybe telescoped over the lower endof the tubular body 11 in the usual manner.
It will be seen from the foregoing that a closure device embodying the present invention may be mass produced on standard types of machines and as a result, production costs are kept to a minimum. Also, the tubular, body may be formed as a one-piece metal part and: will effectively seal the opening in the closure cap without the use of sealing gaskets or the like which are subject to deterioration. The discharge rate may be varied, if desired, by changing the diameter of the cutting head. In addition, the closure device described provides for a quick rupture and a rapid discharge of the contentsv of the container, which is of importance in a fire extinguisher.
It will be understood that various changes and modifications maybe made in the embodiment of the invention illustrated and described herein without departing from the scope of the invention as defined by the following claims.
