[0081] FIG. 1A shows a perspective front view of a device 100 for delivering a dry bulk material such as chocolate sprinkles. This device 100 is suitable for fitting on a pack of cardboard having a pour opening. The pour opening is well known in the art, and is usually made of plastic with a circular cross section and can be closed off with a plastic screw cap.

[0082] FIG. 1B shows a cross section of the device 100 of FIG. 1A, looking in the direction away from the front side of the device. FIG.

[0083] 1C shows a front view of the device 100.

[0084] The device 100 has a first end 101 and a second end 102.

[0085] A body 105 is shown having a first chamber 110, a second chamber 120 separated by a divider wall 130, wherein the first chamber 110 and the second chamber 120 are connected via a transition chamber 140 having a back wall 141 (FIG. 2B). The first chamber 110 is situated at a first side 131 of the divider wall 130 and the second chamber is situated at a second side 132 of the divider wall 130. The first chamber 110 provides a lateral opening 111 for allowing dry bulk material to enter into the first chamber 110.

[0086] The transition chamber 140 comprises an inlet 142 at the first side 131 of the divider wall 130, which permits the dry bulk material to end up in the transition chamber 140 via the first chamber. The dry bulk material can exit the transition chamber via a passage opening 143 and then ends up in the second chamber 120. The dry bulk material can exit the second chamber 120 via a dispensing opening 151 in a front wall 150 of the device 100 at the first end thereof. By way of decoration the front wall 150 is provided with eyelets which, together with the dispensing opening 151, represent a face (FIG. 1C).

[0087] When the device 100 is held horizontally the dry bulk material will fall on the first side 131 of the divider wall 130. By tilting that dry bulk material will slide over the divider wall 130 into the transition chamber 140. By tilting back again the dry bulk material will exit the second chamber 120, and it will exit the device 100 via the dispensing opening 151.

[0088] The embodiment illustrated in FIG. 1 includes a collar 106 which can cover a plastic section of a pour opening of the pack that is protruding from said pack. Therewith the collar 106 may clamp the plastic part or by contacting a wall of the pack prevent the device from ending up in the interior of the pack.

[0089] The plastic device described here is also suitable for dispensing liquid.

[0090] FIG. 1D shows a device 100 similar the one of FIG. 1A fitted in a neck 171 of a bottle 170 that contains a flowable material 191, here a liquid. The liquid may be dispensed portion-wise.

[0091] The device 100 of FIG. 1 is made of plastic and comprises two device sections (FIG. 2A) both of which can be manufactured by means of injection molding.

[0092] The first device section 210 comprises the front wall 150 and the divider wall 130. The second device section 220 comprises the transition chamber 140 with back wall 141 (FIG. 2B).

[0093] In the embodiment illustrated here the second device section 220 is in the form of a cap for the first device section 210, which is connected therewith by clicking. Recesses 221 can be seen for receiving the divider wall 130.

[0094] For a given first device section 210 the length of the a second device section 220 can be adapted to provide the desired dosage. In other words: The injection mold for the first device section 210 can be the same, thus saving cost.

[0095] FIG. 2B shows a view of the second device section 220, in the longitudinal direction of the device 100.

[0096] FIG. 2C shows a schematic longitudinal sectional view of the device 100 of FIG. 1A.

[0097] For a dry bulk material the volume of the first chamber 110 is advantageously larger than that of the transition chamber 140 and the latter, when the device is turned back upright, is completely filled up to the edge 243.

[0098] In case of a liquid the volume of the first chamber 110 is advantageously smaller than the volume of the transition chamber 140. Hereby it is avoided that liquid will flow over the divider wall 130 back into the first chamber 110.

[0099] FIG. 3A shows a perspective view on the interior of the upper part of a cardboard pack 390. In FIG. 3B that part is provided with a device 100 according to the invention as discussed above.

[0100] FIG. 3A shows a roof shaped top side comprising two angled roof sections, that is a first roof section 391 provided with a pour opening 393 and a second roof section 392. The roof sections and folded in wall parts of the cardboard pack 390 provide internally a pyramidal shape, which will lead the dry bulk material automatically to the device 100. Now, the device 100 is fitted in the pour opening 393 in such a way (FIG. 3B) that the lateral opening 111 faces the point of the pyramidal shape. The little face at the first end 101 increases the likelihood that even without instructions the user will orient the device correctly for proper functioning thereof. When tilting the pack the dry bulk material will fall from the corner of the pyramidal shape into the first chamber 110.

[0101] FIG. 4 shows a side view of a cardboard pack 400 with a top side wall 401 and a bottom 402 and in a sidewall 403 a pour opening 470. The pack 400 comprises a retractable tab 471 for closing off the pour opening 470.

[0102] A body 405 that includes a divider wall 430 is fitted into the interior of the pack 400. The pack 400 comprises a first chamber 410, a second chamber 420 and a transition chamber 440. Dry bulk material present in the first chamber 410 can reach the pour opening 470 via the transition chamber 440 by tilting the pack 400.

[0103] The back wall of the transition chamber 440 is formed by the bottom 402 of the pack.

[0104] By connecting to the divider wall 430 to the top side wall 401 the direct passage of the dry bulk material from the first chamber 410 to the second chamber 420 is prevented preferably completely.

[0105] FIG. 5 shows a horizontal cross section of the cardboard pack 400 of FIG. 4. The inlet 442 can be seen via which bulk material from the first chamber 410 can end up in the transition chamber 440. When the pack is relatively full, there is no need to tilt the pack for this. When the pack is getting empty (to below the upper edge of the transition chamber 440), the pack 400 will be tilted in order to introduce bulk material in tothe transition chamber 440. As a result the dry bulk material will end up on the divider wall 430, and upon tilting back will then slide into the transition chamber 440.

[0106] FIG. 6 shows a blank 600 for manufacturing a body 405 for a pack 400.

[0107] The blank 600 can also provide the tab 471 directly with side flaps 472. Folding lines are shown dashed. To form the body 405 from the blank 600 sections of the blank folded against each other will be connected by gluing to one another. However, the body 405 can also obtain or maintain its shape by placing it in a packaging, and be secured by clamping and/or glueing in the pack.

[0108] FIG. 7 shows a perspective view on the body 405, with the inlet 442 and the tab 471 with side flaps 472.

[0109] FIG. 8A to FIG. 8C show a front side of an alternative embodiment of a pack 800, a cross section of the pack 800 in a closed state and a cross section of the pack 800 in a usage state.

[0110] FIG. 8A shows the front side of a cardboard pack 800, more specifically the front sidewall 403, in which there is a perforation 831 which defines the cardboard part of a half-circular lip section 830. By pressing the lip section 830 inward the cardboard of the front sidewall 403 will tear, resulting in a lip section 830 with a free distal end 832. This distal end 832 presses the divider wall 430 inward until it ends up on the top side of the top edge 843 thereof (FIG. 8C), which blocks the the lip section 830 from moving back. The pour opening 470 is now free and the contents of the pack 800 can flow out hindered by the lip section 830. After pouring the divider wall 430 can be pushed inward with a finger again, freeing the distal end 832 of the lip section 830 becomes free and so moves back because of the resilient character of the cardboard. The moving back can be enhanced by using a resilient element 860, such as a plastic plate.

[0111] When this resilient element 860 protrudes to beyond the circumference of the cardboard part of the lip section 830, the resilient element 860 also acts as an abutment as a result of which the pack 800 stays perfectly closed (corresponding to FIG. 8B). Such a packaging is for instance suitable for rice, cereals and the like.

[0112] FIG. 9A shows a blank 900 for manufacturing a cardboard pack 800 provided with a resilient plastic element 860 in the form of a sticker.

[0113] FIG. 9B shows a cross section of the pack 800 of FIG. 8A made of the blank 900 of FIG. 9A in a glued, folded state, wherein glue 901 is indicated.

[0114] FIG. 9C shows a horizontal cross section of the pack 800 manufactured with the glued blank of FIG. 9B in a folded out state.
