UNITED STATES PATENT OFFICE CLOSURE MEANS FOR TUBES AND THE LIKE Ingwald Martinius Evensen, Weston, Ontario, Canada Application March 11, 193 7, Serial No. 130,260.

' 2 Claims. (01. 221-60) companying drawing that forms a part of'the.

same.

The invention consists essentially of the novel features of construction pointed out broadly and specifically in the claims for novelty followinga description in detail of an acceptable form of the invention.

The objects of the invention are to devise a closure means for tubes and other containers for retaining liquids and semi-liquids as well as other matters of a similar nature, e. g., toothpastes, oil tubes, vaselines, shaving creams and innumerable other commercial articles; to facilitate matters for the consumer in enabling him to remove the contents from the tube without getting his fingers smeared, which so often occurs in the use of ordinary capped tubes; to insure a tight closure for the tube and the consequent saving of the contents thereof; to eliminate the constant irritation and annoyance caused by the frequent losses of the caps of the tubes, and thereinplace substitute a cap that will be a fixed part of the tube itself and at the same time can not only be easily raised or lowered but securely locked in its closed position; to materially reduce the loss of the tube contents owing to the fact that by using this particular closure the unused contents of the tubes thatmay still project beyond the neck of the tube will be forced back into the tube rather than therearound, when the closure is closed; and generally to provide a very serviceable, durable and efiicient closure means at the minimum cost, that may be used for many varied purposes.

In the drawing:

Figure 1 is a. perspective fragmentary view of the tube without the closure means.

Figure 2 is a perspective fragmentary view of the tube with the closure means mounted thereon. Figure 3 is an assembly view of the different parts of the closure shown in perspective.

Figure 4 is an enlarged fragmentary sectional view of the tube with the closure means mounted thereon.

Figure 5 is an enlarged fragmentary sectional view of the tube and closure means in right angle to the view .shown in Figure 4.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the closure means is in the form of a cap as indicated by the. numeral ll having the lid II and the hinge bearing l2 and the central projecting curved boss l3 and the finger grip I4.

The lid II is pivotally secured to the cap l0. by the hinged pin 20. The curved boss l3 fits into the can In and into the tube. l5 when the 5 lid l I is turned down on the cap. The cap III has the orifice or groove l6 and the smooth vertical surface I! which is engaged by the finger grip H, when the lid is brought down on the cap. 'At the same time the spring I8 is pressed down into 10 the orifice or groove IS. The cap is internally threaded for engagement with the externally threaded neck 19 of the tube 2|. The cap II) has the groove 22 adapted to 'receive the spring 18 when the cap is locked to the tube.

All that is necessary is to turn the cap on the neck of the tube until the spring l8 engages the recess 22. The curved part of the spring I 8 follows the threads on the neck of the tube, and this spring is consequently forced into the recess 22, thereby locking the cap to the tube.

.For unlocking the closure means, .the cap is simply turned back to its original position, the spring I8 will then return to the sniooth vertical surface 23, on the neck 24 of the tube 2|, and by 25 pressing the finger grip l4 upwardly the. lid can be raised.

In other words, it is the turning of the cap on the neck of the tube that locks and unlocks the lid and consequently the cap to the tube. The curved boss l3 fits tightly into the neck of the tube and prevents the escape of the contents of the tube during the operation and at the same time it prevents the contents from becoming hardened due to exposure to the air.

It will be seen that it is not necessary to remove the cap from the container, the turning of the cap on the neck of the tube will allow the free use of the contents of the tube when desired.

It is of course understood that the closure 40 means herein described may be formed with slight modifications for other purposes apart from tubes, such as cans, pipefittings, bottles, radiator caps on automobiles, and on innumerable other objects, without departing from the scope of this invention.

What I claim is: 1. In closure means for tubes and the like, a container having a tubular seat member externally threaded and having a vertical smooth sura spring secured to said lid and having a tongue and adaptedto fit between the tubular member and the cap and to engage with the. groove of the cap in the closed position of the lid.

2. In closure means for tubes and the like, a container having a. tubular seat member externaliy threaded andhavingasmooth surface breaking the threads, an internally threaded cap having a vertical groove on its inner side and engaging with the tubular seat member 0! said container, a. lid hingedly secured to said cap and having a central projecting curved boss, a finger grip projecting from said lid, and a springaecured to said lid and having a tongue and adapted to fit between the tubular member and the cap and to 5 engage with the groove of the cap in the closed position of the lid.
