In the several'lforniszoffthelinventiondisclosed, thererisincludedra container havinga tubular body of substantially; rectangular 'form, in crosssection, a sheetmetal bottom head; a sheetwrnetal apertured top head, a slideivalveor-slidableplo-- sure; guide+ways-ior the closure; and moreparticularly; the1-slide=valve controlsa relatively; large:

However, the .dominatingtfeatureof .the; lumen-- tion resides in providing a counter-sunk top head, having a spoon opening and an embossed or raised rib surrounding the opening, with fiat horizontal side wall seats running parallel lengthwise with the opening on opposite sides thereof, and in providing fiat inclined end wall seats which merge at the lower corner portions thereof into the horizontal side wall seats adjacent the open ends of guide-ways for a slide valve so as to flex on an inclined plane opposite ends of the slide valve at the junctures of the horizontal side wall seats with the inclined end wall seats.

Referring to the drawings I disclose a container which includes a tubular fibrous, or paper body A of rectangular cross-section, having a sheet metal imperforate bottom head B and a sheet metal sifter and open top head provided with a slide valve, or closure member D. The bottom and top heads are united to the body A in any suitable manner, as by seams well known to the container art.

The top head C is formed with a countersunk horizontal wall or panel section I, which at its outer edges, merges into surrounding vertical side wall sections 2 and similar end wall sections 3 merged together by curved corners 4. The wall sections 2 and 3 are disposed within the top end of the tubular body A and engage against and extend above the walls of the body A. The upper edges of the wall sections 2 and 3 merge into outer marginal portions 3' preferably bent, or crimped over the top edge of the body A into tight engagement with the outside of the body A. This produces a top seam which unites the top head C with the top of the body A and provides a top rim 5 for the container.

The top head C is also provided with an embossed, or raised rib designated, generally, as 6 and of rectangular form which, preferably, conforms with the shape of the top head C. The rib 6 is drawn to provide inclined outer side walls I and similar end walls 8 joined by rounded corners 9.

At their bases, the inclined outer walls I and 8 of the rib 6 merge into the countersunk horizontal wall section I. I

As shown in Fig. 5, the rib 6, as initially formed, is also drawn to provide vertical inner side walls. It, the upper edges of which walls merge with the upper edges of the inclined outer walls 1,

and at their bases the vertical inner Walls I0 merge into narrow fiat horizontal side wall seats II disposed in a plane with the countersunk horizontal section I. The horizontal wall seats I I are disposed on opposite sides of a punched out opening I2 of rectangular shape as shown in Fig. l, which conforms substantially with the shape of the top head 0 and of a length to accommodate the width of an ordinary teaspoon. Also the rib 6 is drawn to provide opposed flat inclined end wall seats I3, the upper edges of which mergewith the upper edges of the inclined outer end walls 8, and the corner portions of the lower edges of the flat inclined end wall seats I3 merge into the ends of the opposed flat horizontal side wall seats II, while the free lower edges of the fiat inclined end wall seats II define the end edges'of the opening I2.

Guideways I4 are provided on opposite sides of the opening I2 above like outer edge portions of the upper faces of the fiat horizontal wall seats II by downwardly and inwardly deforming the inclined outer walls 'l and the inner vertical side walls I0 of the-rib 6 to form horizontal beads t5 after the slide valve D has been positioned over the opening I2 and the seats II and I3 and forced into contact with the horizontal and inclined wall seats II and I3, respectively, through the bead forming operation. The slide valve D thus mounted on the top head C is then slidable or shiftable longitudinally, in either direction, as desired, between the guideways I 4.

Through efficient utilization of the area of the flat horizontal wall seats II and the fiat inclined end wall seats I3, as above described, it is possible to make the opening I2 quite large with respect to the size of the container, especially for the insertion of the spoon through the opening I2.

The present embodiment of the invention contemplates utilization of the opening I2 to facilitate withdrawal of different measured quantities of material from the container through the use of an ordinary teaspoon F and to this end, the Opening I2, as shown in Fig. 1, has both of its long edges I6 formed straight so that the con.- tents withdrawn on a spoon E shown in Fig. 1, can be leveled off on a selected straight edge, if so desired. Thus, as shown in the drawings, the opening I2 is of such size both in length and in width as to permit the passage of the bowl of an ordinary teaspoon so that the bowl may be withdrawn from the container with its side edges in contact with either opening edge I6 selected to level off the contents on the spoon, or due to the fact that the width of the opening is greater than the depth of the spoon bowl, the outer curved face of the spoon bowl can contact one edge of the opening so that a heaping spoonful of contents can be withdrawn from the container.

To maintain the spoon opening I2 at the maximum, in a minimum size top head C, and thus adapt the top head C for use on minimum size condiment container bodies A that are substantially rectangular in cross-section, and at the same time provide a slide valve, or closure member D therefor which will normally lie below and within the bounds of the top rim 5 of the top head C, as well as one that can be easily and quickly moved to cover and uncover the spoon opening I2, and, at the same time be retained in its closed position against accidental displacement from any cause, I have especially designed the slide valve seats II and I3 on the apertured top head C to afford maximum areas therefor to prevent leakage of the container contents when the slide valve, or closure member D is in its closed position, and to provide substantial bearing surfaces for the slide valve to slide upon, and to this end, I have provided the opposed flat horizontal wall seats I I and fiat inclined end wall seats I3 to occupy positions surrounding the spoon opening I2 for the accommodation of the slide valve, or closure member D, the material of which is more or less flexibly resilient in order that the end portions thereof beyond the ends of the spoon opening I2 when the slide valve is in closed position, will be flexed upwardly on an inclined plane while the intermediate portion of the slide valve fully closes the opening I2 and lies in a substantially flat horizontal position relative to the inclined end portions thereof.

The slide valve, or closure member D, as shown in Fig. '7, is provided with a plurality of sifter openings I I which are so positioned relative to both ends of the member D that they will be closed by lying over the flat inclined end wall seats I3 when the slide member Dis in its fully smash shown in one instance in Fig. 9, causes the spoon I opening I 2 to be partially uncoverednear one end thereof to provide a pouring opening .I8 through'which contents of the container can be poured.

In order to afford means to prevent accidental shifting movement of the slide member D, when in closed position, I provide the free inner edge portion of each flat inclined wall seat I3 with a channeled seat I9 drawing the material into channel formation between opposite corners of the spoon opening I2 to receive outer transverse ribs 20 formed on the slide member D. And, in order to prevent accidental shifting movement of the slide member D when moved to either sifter position, I provide the slide valve D with inner transverse ribs 2I spaced from ribs 20, one of which will be seated in one of the channel seats I9, thus providing a stop for either sifter position of the slide valve D.

The channeled seats I9 at the inner edges of the inclined end wall seats I3 and their respective cooperating slide valve ribs 20 serve also to form a seal between the slide valve D and the fiat inclined end wall seats I3 to guard against leakage of contents from the container, especially during transportation thereof, and effectively seals the container when the slide valve D is in its closed position, as shown in Figs. and 16.

It will be further apparent from Figs. 4, l5 and 16, that the elongated flat horizontal wall seats II are disposed in a substantial plane with the top head wall section I, and by reference to Figs. 15 and 16, when the slide valve D'is in its closed position on the horizontal wall seats II, and inclined end wall seats I3, that the intermediate major portion of the slide valve D is disposed in a flat horizontal position between the inclined end wall seats I3 and does'not drop below the lower plane of the flat horizontal wall seats II, or the horizontal top head wall I, which is an important feature of the invention, to avoid complicated deep drawing operations, lends to the appearance of the top end of the package, and effects a slide valve in which accidental longitudinaldisplacement thereof is minimized, due to the end portions of the slide valve D assuming. positions in inclined planes relative to the fiat horizontal position of the relatively long intermediate portions of. the slide valve which lies on the flat horizontal wall seats I3 when the valve member is in its closed positions, as illustrated in Fig. 15 due to the fact that the inclined end portions of. the slide valve set up resistance. to accidental sliding movement, further aided by the. channeled seats I9 and slide valve ribs cooperating therewith, which channeled seats I9 and ribs 2E! serve to seal the ends of the spoon opening against leakage of container contents, particularly if the container is upsidedown, or lying on either si'de during transportation thereof. I

" In the modification shown in Figs. 7 to 10, inclusive, the spoon opening I2 is somewhat different in shape than the spoon opening l-2 in Fig. 14, in that it has but one straight edge I6, while the opposite edge of the opening is curved, as at I6. This particular opening is designed to accommodate a regular measuring spoon F of the teaspoon capacity; which is wider across the edges of the bowl than a regular teaspoon, thus the opening will also accommodate a regular teaspoon. To this end, I provide-a opposite corners of the spoon opening I2 in the top head C with a recess 22, communicating with the opening I2. One end of the arc shapeedge of each recess 22 merges with the ends of the straight edge It and the other end of each recess merges into a curved edge 23. This edge, in turn, merges into a straight edge 24 at the inner edge of the channel seats I9, which merges into a curved edge 25, which, in turn, merges into a straight edge 26 at the medial line of the head C, which merges with the ends of the curved edge a e. The slide valve having the sifter openings I1 is also employed with this type of head C. However, in this instance, three or half of the sifter openings I'I register with the spoon opening I2 when the slide valve D is moved into sifter position, as shown in Fig. 8, and the other half or three sifter openings register with a like number of sifter openings H in the flat horizontal wall seat II, which openings are clearly shown in Figs. 9 and 10. In Fig.9, the slide valve is shown as moved into pouring position to provide the pouring opening I8. In this modification, the sifter openings IT can be formed in one end only of the slide valve D, instead of both ends thereof, if so desired. v

In the modification shown in Figs. 11 to 14, inclusive, the spoon opening I2 is similar to that shown in Fig. 1 only having corner recesses 22, and instead of the sifter openings being formed in the slide valve D, the openings are'formed in the flat inclined end wall seats II and are designated II, and there are no openings formed in theslide valve D, as shown in Fig. 3, which shows the slide valve as it appears in top plan view without openings. It is, of course, understood that sifter openings can be formed in both fiat inclined end wall seats II, if so desired.

The modification illustrated in Fig. 18, as far as thehorizontal wall seats and the end wall seats are concerned, is the same as in the top head shown in Figs.' 3, l5 and 16, except that the inclined end wall seats designated I3 are suitably curved relative to the flat horizontal wall seats I I instead of being flat inclined Wall seats, as illustrated in above mentioned figures of the drawings.

It will be apparent'that in the several styles of top heads C shown, that fiat horizontal wall seats are provided on opposite sides of the spoon opening I2, which are in a plane with the countersunk head wall I, regardless of the shape and. size of the opening, that the fiat inclined end wall seats are the same, that the guideways are the same, and, also the slide valve D is the same in every-particular except for the number and location of the sifteropeningstherein, with the one exception where there are no sifter openings formed in the slide valve D, as shown in Figs. '3'and 11.

It is to be remembered thatthe aperturedtop head member vC and the slide valvetherefor, zis sodeSigned as to beiadapted 'fornse ini'connec-v tion with the smallest size of condiment, or like container bodies, as well as the larger sizes, and particularly rectangular container bodies which will not accommodate a spoon opening, transversely or diagonally thereof, and which will permit of the use of a slide valve or closure member which can be completely removed and replaced from either end thereof, and which will lie below the rim 5 of the top head 0 when fully; closed, and wherein any portion thereof will not lie below the lower plane of the flat horizontal wall seat H or II and Il and the countersunk head wall I.

1 In each instance, however, the slide valve D isprovided with a-suitably-shaped embossed or raised button like portion 21 to facilitate sliding movement of the slide valve and the slide valve can also-be provided with direction arrows 28, if so desired, to indicate the direction, or direc tions in which the slide should be moved to sifter position. e

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art of container manufacture.
