(Cl. 221-23) This invention relates to can spouts adapted tin can as it appears when the spout has been to be punched through the top of a metal can removed, and showing the two semi-circular containing a liquid, and more particularly to a holes pierced therein by the insertion of said can spout of the above nature having interspout.

When the spout 10 has been inserted in the can top, but is not being used for pouring purleaving a narrow bridge between said wings, a pair of radial lugs located between said cutters for forcing said wings downwardly, exterior packing means adapted to engage the top of said poses, the open end of said spout may be sealed can located adjacent said knives and surrounding by means of a cylindrical slip cap or cover 28, which is detachably fitted over the pouring end of said spout 10, as shown in Figs; 1 and 2. When the spout 10 is detached from the can,'the cover 28 may be reversed and slipped over the

cutting knives

12, 12 of the spout 10, as shown in Fig. 4 to serve as a protective guard for the same. The cover cap has a domed head 29 adapted to fit the hand of the user when forcing the spout into the can top, and protect it from being cut by the end of the spout.

Operation In operation, when it is desired to open a can, the cover cap 28 will first be removed from the cutting knives 12, and slipped over the opposite or pouring end of said spout. With the cover 28 thus assembled, the spout 10 may then be placed on the top of the can 17 in the position shown in Fig. 1. Force will then be applied to the spout, causing the

points

15, 15 of the

cutting knives

12, 12 to puncture the top surface 16 of the can. The spout will then be swung back and forth in such a manner as to cause the

knives

12, 12 to cut out the pair of opposed openings 19 in the can top 16, as shown in Fig. 6. When the spout 10 has been pushed inwardly as far as it will go, as permitted by the flange 25, the spout will be twisted in a clockwise direction to firmly interlock the necks 24 of the bridge 20 in the slots 23 and hermetically seal the spout upon the top of the can 17. The can is then ready for pouringthe liquid through the spout.

In order to detach the spout from the can after. the desired quantity of liquid has been poured out, it is only necessary to twist the spout in a counter-clockwise direction until the

slots

23, 23 are clear of the

necks

24, 24 of the bridge member 20, and then pull straight out on the spout 10.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.
