' GONTAINER I Filed Jan. 24,- 1955 thereof.

Patented 1937 PATENT OFFICE CONTAINER John M. Hothersall, Brooklyn, N. Y., assignor to American Can Company, New York, N. Y., a corporation of New Jersey Application January 24, 1935, Serial No. 3,328

'6 Claims.

'The present'invention relates to sifter top dispensing containers and'has particular reference to a protective hermetic seal for the sitter dispensing outlet of such containers.

An object of the invention is the provision of a hermetic seal for a sifter top container which permits the container to be vacuumized, the seal Numerous other objects and advantages of the invention will beapparent as it is better under-- stood from' the following description, which, taken -'in connection with the accompanying drawing, discloses a preferred /embodiment Referring to the drawing:

Figure 1 is a perspective view of a container with a protective hermetic seal embodying the instant invention;

Fig. 2 is an enlarged plan view of the top construction of; the container illustrated in Fig. 1 showing the seal partially broken away;

Fig. 3 is an enlarged fragmentary view. partly in section and partly in side elevation, taken substantially along the line 3-4 in Fig. 2 showing one side of theseal before breaking.

Fig. 4 is a. view similar to Fig. 3 showing the same side of the seal after breaking; and

Fig. 5 is an enlarged sectional view of the I upper part of the container taken substantially along the line- 5-5 in Fig. 2 showing the seal broken 'on one side as illustrated in Fig. 4 and on the other side still intact.

As a preferred embodiment of the the drawing discloses a tubular bodygll having a top end member l2 and a bottom end member secured to the body in any suitable manner as by 45 seams I3. I w

With reference to Fig; 5, the top member l2 comprises an annular horizontal outer panel M which merges into a vertical'wall section l5 which -merges into a curved wall section or shoulder I6 which in turn merges into a depending vertical invention l3. From the lower-end oi the wall section II the material of the top member extends substan;

tially horizontally, except for an annular channel depression 18, to form a central sitter slide support or'panel IS. The panelwall i8 is provided with a dispensing opening 2| (also Fig. 2)

which is closable by a rotatable disk 22 pivotally connected at the; center of the panel 19. This disk is provided with a group of Sifter periora tions 23 and a pouring-aperture 2l, whleh group or aperture is respectively coextensive and may I be moved into register with the dispensing opening 2| in the usual manner for'dispensing the container contents. The. container interior is adapted to be vacuumizedthrough the dispensing openings in the wall- 19 and in the disk 22 and in order to hold the vacuum the container must be hermetically sealed. This sealing iseflfectedby a'cap or cover -25 which engages over the top of the seal receiving rib'or ridge.- This cap preferably comprises .a circular substantially fiat central panel or wall 26 -(Flg. 5) which at its outer marginal edge merges into an. inverted shallow channel wall section 21 which curves over the top ofthe curved wall section or shoulder l6 of the rib and terminates in a depending fiange'28, This flange extends down parallel with the. rib wall section and is in tight. fitting engagement therewith.

A gasket 28 of compound or other suitable material is carried-in the channel 21 and is interposed between the channel and the rib shoulder I 6. In this manner the container is hermetically sealed when the cap 25 is fully applied, and the vacuum created therein is heldand at the same {time the cap 25 protects the sifter construction against tampering until the seal is removed by the ultimate consumer.

To remove the cap 25 it is provided with a pair of opposed tearing tongues 3l formed in the flange 28, 'which is extended and curled at these points to provide outwardly curled finger holds 32 for ready engagement and tearing. v

To facilitate the tearing action a pair of slits or .openings 33, which may also take the form of score lines, is cut in the cap flange thereby defining the outlineof each tongue.

' In tearing the tongue away the material of l the flange first tears from the flange edge, adjacent each edge of the. curl 32, into the slits 33, as

then be'lifted and the tearing continued from the upper ends of the slits through and beyond the sealed part of the 'cap. Tearing beyond the so 1 .shown in Fig. 4, which'tearing may be done with only a slight, pulling'action. The tongue may;

seal immediately breaks the vacuum in the con.-

tainer and permits of removal of the cap with the foregoing description, and it will be apparent that various changes may be made in .the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbetore described being merely a preferred embodiment thereof.

I, claim: 1

LA dispensing container comprising in combination, a container body having a top end secured thereto provided with sitter means, said top end having an upstanding wall portion disposed inwardly of the container body walls surrounding and extending vertically above said sitter means, and a cap engaging and hermetically sealed to said wall above said sitter means whereby to hermetically seal said container and I protect said sitter means against tampering uncured thereto provided with sitter means, said til said sealing cap is removed.

2 A dispensing container comprising in combination, a body, an end closure secured thereto, sitter means in said closure, a wall in said closure surrounding and extending vertically above said sitter means, and a removable cap engaging said wall and hermetically sealed thereto above said sitter means to hermetically seal said container and to protect said sitter means.

3. A dispensing container comprising in combination, a container body having a top end setop end having an upstanding wall portion disposed inwardly ot the container body walls surrounding and extending vertically above said sitter means, and a cap engaging said wall and hermetically sealed thereto abovesaid sitter means to hermetically seal said container and to protect said sitter means, said cap having weakened portions extending inwardly from an edge thereof and defining a tongue for rupturing said cap beyond said hermetic seal to facilitate its removal.

4. A dispensing container comprising in combination, a container body having a top end secured thereto provided with sitter means, said top end having an upstanding wall portion disposed inwardly ot the container body walls surrounding and extending vertically above saidsitter means, and a cap engaging said wall and hermetically sealed thereto above said sitter means to hermetically seal said container and to protectsaid sitter means, said cap having slits extending inwardly from an edge thereof and defining a tearing tongue for rupturing said cap beyond said hermetic seal to facilitate its removal, said tongue having a finger hold extension tor gripping it during the rupturing operation.

5. A dispensing container comprising in combination, a body closed at both ends with end closures, sitter means in one of said end. closures, an upstanding wall formed in said closure surrounding and projecting above said sitter means, a cap for hermetically sealing said sitter means and spaced above the'latter, said cap having a depending flange for tightly embracing said upstanding wall in friction engagement therewith, a sealing medium between said cap and said wall for hermetically sealing them together, and a tongue formed in said depending flange for tearingthe same so that said cap may be removed.

6. In a dispensing container in combination, a tubular body, end closures hermetically secured to said body, a dispensing outlet in an end closure of said container, said end closure having an up standing wall spaced inwardly from the walls of said body surrounding and projecting above said outlet, a' cap adapted to be hermetically secured to said wall to enclose said outlet, said wall and cap cooperating to permit vacuumizing said container through said outlet and to hermetically hold said vacuum.
