Application October 3, 1949, Serial No.=119,270

4 Claims. (01. 222-90) .provements in dispensers;

:-An object. of -.this inventionis to. pierce. a.- can eorxother container havinga pierceableportion by .means of.a hollow.member,..as.a tube, which. has

:asharpened end andthen. retain the tube in the :container so that the contents "of the container zorlcanmaywbe poured through the tube.

Another object of this invention is to seal the tube tight withthe top ofthecan so as to prevent :leakage whilethe-contents of-the can isbeing zpom'edtherefrom.

rtfurther object of-this invention is to-resil- :iently: retain the'sealagainst the top .of the-can and at the same time maintain the tube fixed in the container. I

Other objects and features willbecomea-p- 'parent-in following the illustratedform ofthe invention. r

Figure 4 is afragmentary elevational view of one of the projections in apart of the tube on which the projection is'disposed;

.I-Figure Bis a front view of the detail of construction shown in Figure 4. I 1

The device may :beemployedin connection with any type of container, can orthe like wherein. it is found practical and desirable. A metalliccan or'container i'fl'is'illustrated having a top I2.

A hollow member, as a tube I4 is provided with asharp'end portion- I6 which'is employed for piercing the top ii of the can It]. Lateral openings I 8 are provided in the tube adjacent the sharpened portion or sharpened end thereof so as to allow the contents of the can to be poured therethrough as well as through the open sharpened end of the device.

A seal which is in the form of a resilient ring is disposed in a carrier or retainer 22. The ring is preferably rubber and has an inwardly extending concentric ring 24 integral or rigidly fixed therewith. The ring 24 is adapted to seat in the groove 26 which is formed peripherally of the tube l4.

The retainer 22 has an annular seat 28 formed abutment for one end of the spring 32. .tainer vas well astheseal has a central passage therein wherein the seal 20 is disposed. A flange .30 also i'ormsa part of the retainer and forms an The retherein accommodating the tube I4.

Thecspring=32 seats on the, abutmentflfl and :-also one. shouldenwhich may be formed by the -.washeri 34,-,fixed to the exterior surfaceof the tube I4 and spaced from the retainer. Accordingly, the spring reacting on the tube-and the retainer, constantly .pushes the retainer together withthe seal. downwardly toward the top l2 of thecan.

An upper. limit; stop 133 1 fixed, to thezexterior surface ctthe tube and disposed within the re- .tainer; 22. 'A lower limitstop 40 is also fixedto the exteriorsurfaceof the tube and on the other -side-of the .gro0ve.:26 with respect to the stop 38. .The. function of the stop '38. is to limitthe downvwardtravel of the. retainer 22 with respect tothe tube, The function of the lower-stop is'to ;-limit the downward movement .of the tube through the top [2 of the can.

.Aipair of projections 42 and (44 respectively are formed on the exterior surface of the tube below the stop: 40. .These. projections are passed through-openings 46 and which are formed in the top E2 of the can as the tubeis forcibly thrust therethrough.

In operation, the sharpened enct I f the tube -is pressedthrough thetop12 of the can. lIt is -pushed inwardly until-such time as the upper surface of the top i2 engages the stop 40. -'-At that-time, the recesses' IB- and Attire-formed" on opposite-sides of the opening which isformed by the tube in -the-cantop. Then, the tube "His rotated -so that the upper surfaces of the I enlargements or projections 42 and *44 engage the undersurface of thel'top I 2. This holds the tube impl-ace.

When the tube M 'has penetrated the top of'the can an=-amount sufiic-ient to have the uppersurface of the top I2 strike the stop 40, the resilient seal 20 has been pushed upwardly against the force of the spring 32. Accordingly, the spring 32 forcing the retainer 22 downwardly constantly presses the seal 20 against the upper surface of the top of the can. This forms a substantially fluid tight seal and any leakage is received in the chamber 50 defined by the inside surface of the seal 20, outside surface of the tube l4 and the connecting membrane 52 which joins the ring or bead 24 with the body of the seal 20.

When it is desired to remove the device, it is only necessary to rotate it so that the projec- 3 tions 42 and 44 pass through the recesses or openings 46 and 48.

The specific structure of the projections 42 and 44 is of importance. Reference to Figures 4 and 5 show the actual structure best. The projection has a lower end tapering to a point, as at 69, but blending into the material of the tube l4. Moving upwardly on the projection 42 the smoothly surfaced projection grows larger to a maximum, as at 52. and thickness region there is the beginning of a taper in the opposite direction from that taper extending from the lower end 60 to the maximum point 62. However, the upper taper does not terminate in a point but rather in a shoulder As the tube is pressed through the top of the container If], at the obvious part of the downward travel of the tube, the lower end portions 60 begin to spread the material of the top adthat the tube i4 is rotated so that the shoulders 64 abut the undersurface of the top l2 of the container I9.

In removal of the device from the container 19, the spring 32 assists. The tube 14 is rotated until such time that the projections 42 and 44 may pass through the openings 46 and 48. Since the taper from the shoulder 64 to the maximum thickness region 62 is formed so that the smaller part is adjacent the shoulder and the larger part is downward thereof, this taper acts in the nature of a guide whereby the projections are passed through the openings 46 and 48 very easily, as assisted by the spring 32.

Having described the invention, what is claimed seal disposed on said hollow member with one stop adapted to engage the carrier to limit the relative travel of the carrier and the hollow member, the other stop being located above the loweredge of said seal and adapted to engage the can to limit the penetration into the can.

2. A can opener and dispenser comprising a hollow member constituting a spout and having a harp cutting end, said member having a peripheral groove, a pair of spaced stops carried by said member with said groove between said At this maximum width 4 stops, a seal disposed on said member and adapted to engage the can, said seal having a ring disposed in said groove, a carrier for said seal disposed on said hollow member with one stop adapted to engage the carrier to limit the relative travel of the carrier and the hollow member, the other stop being located above the lower edge of said seal and adapted to engage the can to limit the penetration into the can, and a spring reacting on said hollow member and said carrier to press said seal against the can.

3. A can opener and dispenser comprising a hollow member constituting a spout and having a sharp cutting end, said member having a pcripheral groove, a pair of spaced stops carried by said member with said groove between said stops, a seal disposed on said member and adapted to engage the can, said seal having a ring disposed in said groove, a carrier for said seal disposed on said hollow member with one stop adapted to engage the carrier to limit the relative travel of the carrier and the hollow member, the other stop being located above the lower edge of said seal and adapted to engage the can to limit the penetration into the can, and a spring reacting on said hollow member and said carrier to press said seal against the can, and means carried by said hollow member below said seal for releasably retaining said hollow member fixed to the can.

4. A can opener and dispenser comprising a hollow member constituting a spout and having a sharp cutting end, said member having a peripheral groove, a pair of spaced stops carried by said member with said groove between said stops, a seal disposed on said member and adapted to engage the'can, said seal having a ring disposed in said groove, a carrier for said seal disposed on said hollow member with one stop adapted to engage the carrier to limit the relative travel of the carrier and the hollow member, the other stop being located above the lower edge of said seal and adapted to engage the can to limit the penetration into the can, and a spring reacting on said hollow member and said carrier to press said seal against the can, and a pair of projections on said hollow member for engaging the inside surface of the can top when the member is rotated after passing through the lid to clamp said member in the can.
