RECEPTACLE COVER Victor C. Norquist, Kansas City, Mo., assignor to Butler Manufacturing Company, Kansas City, Mo., a corporation of Missouri Application July 14, 1932. Serial No. 622,397

2 Claims. (01. 220-40) My invention relates to receptacle covers and more particularly to receptacle covers of a quick acting type.

It has been common practice to use bayonet 5 joints in can covers to enable their rapid and convenient removal and positioning. in covering relation. It has been necessary when bayonet joints have been used in the past, to cut or form slots in the covermember to enable the pintles of the bayonet joint to cooperate with the bayonet slots. metal by removing part of the supporting structure. When a particularly tight closure is desired, the bayonet slots are apt to spring, particularly if they are of a pitch to give a high mechanical advantage.

One object of my invention is toprovide a novel bayonet slot construction in which no slots are used for the pintle entry.

Another object of my invention is to provide a construction in which the bayonet slots are supported enabling a longer slot of small pitch to be used, thus giving a high mechanical advantage enabling the closure to be tightly made.

Another object of my invention is to provide a novel construction in which a gasket receiving groove is formed in an expeditious and simple manner.

Referring now to the drawing which forms part of the instant specification and which is to be read in conjunction therewith, and in which like reference numerals are used to indicate like parts in the various views;

Fig. 1 is a perspective view showing a can fitted 35 with a closure of my invention.

Fig. 2 is a sectional view taken on the plane 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a perspective view of the closure of my invention. v I

The can 1 is'provided with a neck portion 2 which may be welded, riveted or secured to can 1 in any suitable manner. The neck portion 2 is provided with a rolled bead 3 adapted to form a seat for the closure. The neck portion 2 carries spaced pintles 4which are secured to the neck portion in any suitable manner. The closure proper comprises a dish-shaped member 5 9 which is made by stamping, forging, or inany other suitable manner and is provided with a stepped flange 11. Riveted to member 5 by rivets 7 is an annular member 6 which contains bayonet slots 8. Adjacent slots 8 are depressed or groove-like portions 9 which form grooves for When this is done, it weakens the the reception of pintles 4. It will be apparent that the metal of the grooves 9 supports the slots at the pintle entering end so that the slots are supported there and also at their other ends.

By this construction I am enabled to use a long 60 slot having but slight pitch so that a great mechanical advantage is attained which forces the gasket 10 firmly against the seat 3. The stepped flange 11 coacting with annular member 6 forms a gasket receiving grooveas. can be readily seen 35 by reference to Fig. 3. A suitable handle 12 is riveted to the dish-shaped member 5 and forms the operating handle.

In operation, the grooves 9 are aligned with the pintles 4 and the cover is pressed'downwardly 70 bringing the pintles opposite the bayonet slots 8. The handle is then turned, causing the pintles to ride along the bayonet slots which are inclined with a degree of pitch. As the pintles ride along the slots, the cover is forced downwardly, forming a tight joint.

It will be noticed that'my cover is exceedingl simple, comprising but two members, namely adished member and an annular member. The handle, of course, does not form part of the 30 cover, inasmuch as the cover may be operated and used without a handle if desired. It is to be understood, therefore, that I have shown a cover made of two parts only. The ease of manufacture, the rigidity and strength of my 35- construction clearly aremanifest advantages of my construction. The closure formed is exceedingly tight and due to the fact that 'a low pitch is used, there is no danger of the cover accidentally becoming loose so that inflammable i101 liquids can be safely shipped in a container, equipped with a cover of my invention. 7

It will be understood that certain features and sub-combinations are of utility and may be em I ployed without reference to other features and sub-combinations.

This is contemplated by and is within the scope of my claims. It is further obvious that various changes may be made in details within the scope of my claims without departing from the spirit of my invention. It is, therefore, to be understood that my invention is not to be-limited to the specific details shown and described.

Havingthus described my invention, what I claim is: j Y

1. A quick-acting closure comprising in com bination an annular member having a plurality of inclined slots formed therein, the metal of said annular member being pressed to form channelportions adjacent respective slots, said channel portions being adaptedto receive pintles and to permit the entry of said pintles into the slots for coaction therewith when the closure is in operative position on a container, at dish-shaped member and a stepped flange formed integral with said dish-shaped member, means. for rigidly securing said last mentioned member to said annular member, in telescoped relation thereto whereby said stepped flange is adapted to form a gasket receiving space with said annular mem.-

her and a gasket in said space.

portions beingpositioned laterally adjacent the slot' portions and adapted to receive pintles to permit the entry thereof into the slots for coaction therewith when the closure is in operative position on the container.
