    FIELD OF THE INVENTION
    [001] The present invention relates to a metering shell for dispensing products in particular powdered products, such as infant formula or powdered milk. Furthermore, the invention relates to the combination of such a shell with a space-limited package in which the shell can be retained before use. DESCRIPTION OF RELATED TECHNIQUE
    [002] Powdered materials, such as infant formula, have been sold for many years in various forms of packaging. Metal cans were initially the preferred container as they were relatively easy and inexpensive to produce and could be sealed for long-term storage. The seal comprised an aluminum foil placed over the mouth of the container and was removed on first use. As a single container would be used for an extended period, the containers were supplied with reusable plastic lids that closed around the outer edge of the can. A measuring ladle was often included in the container, packaged separately or in the can itself.
    [003] More recently, alternative packaging forms have been made available, which improve on existing cans. Such packages include plastic and laminated container bodies and hinge-lid assemblies having an ease of receiving and retaining a metering ladle. In particular, it has been found that it is not desirable for the ladle to be within the space containing the product as this may place more stringent requirements on ladle production and the introduction of the ladle in a final step is ruled out. Such a package is described in patent document US 2008041861 having a seal to initially close the package and a space between the seal and the upper edge of the container to partially receive the shell prior to use. By retracting the seal from an outer edge of the container, additional space for the ladle can be provided without having to vary the design of the lid. It will be appreciated that this can may be important in cases where a number of shells of different sizes may be needed.
    [004]The latest packaging designs aim to reduce unused space within the packaging. Therefore, it would be desirable to provide an alternative shell construction that can help reduce such unused space. Additionally, it is desirable to provide a combination dosing shell and package that can be adapted to different shell sizes. BRIEF SUMMARY OF THE INVENTION
    [005] According to the invention, a narrow profile shell is provided for dosing powdered infant formula, the shell having a handle and a cup with an open edge and a closed underside, wherein the cup has a width that it is relatively smaller than its length and depth. As a result of this configuration, the ladle can be placed in a lateral position inside the lid of a package with little clearance space. Furthermore, shells of different volumes can vary in depth of the bulge without needing more clearance space inside the package due to the lateral orientation of the shell. In the present context, clearance space is intended to denote the space between the upper surface of the product or a covering membrane and the underside, i.e. the space available for storing the shell. Also, the depth dimension of the shell is that extending from the edge to the underside; the length dimension is that oriented generally in line with the cable; and the width dimension is directed across the cable.
    [006] The shell is provided inside the package and can be placed above the sealing membrane before use. It is also possible for the shell to be integrally formed with the construction of the lid and separated on first use.
    [007] Preferably, the bulge can have an edge generally rectangular in shape. Most preferably, the cup has generally flat parallel sidewalls extending in the width direction. The closed underside of the shell can also be flat. It will be understood that the ladle is not intended for food use and the term "ladle" is not intended to refer to a spoon, such as that used for insertion into a user's mouth.
    [008] In one embodiment, the bulge may not be larger than the cable portion. In another embodiment, the edge has a width approximately corresponding to the width of the cable portion. Thus, the effective use of slack space inside the package can be maximized.
    [009] In certain embodiments, the depth of the bulge is greater than its length. Such a configuration allows for increased volume shells while maintaining the ability to stack with smaller volume shells of the same length dimension. It also ensures that the fixing parts inside the lid can also be tailored to different shell volumes. In one embodiment, the length of the bowl is about 50% greater than its width.
    [010] Most preferably, the shell is stackable and has a tapered or graduated cup that can fit into another shell of similar shape. Although during use of the ladle, stacking may not be necessary, during production and transport of the ladles, stacking can be advantageous.
    [011]The taper can be performed in several ways. In one case, the cup can be tapered from edge to underside at a taper angle of less than 8°, preferably less than 6° and more preferably around 4.5° in both the width and length directions. In this context, the taper angle is given as the angle with respect to the central line or plane of the symmetry of the bulge. In another embodiment, the shells can be graduated, in which a narrower bottom part can fit within part of the wider edge.
    [012] According to yet another embodiment, an elongated opening is provided along the portion of the handle adjacent to the bulge. This prevents the accumulation of powdered milk on the handle during use. The cable part can also include more than one opening. It has been found to be advantageous if the elongated opening has a larger dimension which is less than a width of the handle of the shell. This can prevent unwanted snapping of the shells during production due to the cables accidentally snapping into the openings of other shells.
    [013]The ladle may have any volume suitable for the purpose of dosing required. Preferably, the shell will have a bulge volume between 8 ml and 11.5 ml. However, larger and smaller volume shells may be available for specific dosing regimens, including large 20ml and small 5ml shells. In terms of other dimensions, the cup preferably has an edge width of less than 30 mm, more preferably less than 24 mm and most preferably about 20 mm. The cup preferably has a length at the edge of about 30 mm, but can range from 20 mm to about 40 mm. The main variable is depth, which can range from about 20 mm to about 50 mm. In particular, for a shell with an edge 28 mm long and 19 mm wide, the length dimension may be around 35 mm for a shell volume of 11.5 ml; 22 mm for an 8 ml shell volume; and 27 mm for a shell volume of 9.5 ml. The present invention is particularly applicable to shells having a depth bulge of at least 50% more than the width at the edge. The cable length can be around 70 mm.
    [014] The ladle is preferably provided with arrangements to improve the filling and release of powdered milk or similar. In order to ensure metering accuracy, the shell must be precisely filled without the formation of air gaps or gaps. The ladle should also completely empty by inverting the ladle without excessive agitation. As the shell becomes deeper and narrower, these requirements can become more difficult to learn. Increasing the taper angle of the shell can help with deflation, but at the cost of losing volume. Preferably, one or more small openings are provided along the closed underside of the bowl. These small openings help prevent the formation of a vacuum during the emptying of the ladle, while still being too small for the powdered formula to pass through. Thus, it is understood that the term “closed underside” is to be interpreted to include such small openings.
    [015] Another way in which the best filling of the cup bulge can be accomplished is by providing the underside of the bulge with a transition section providing an extended transition between the underside and an end wall of the bulge that is relatively less abrupt than a transition between the underside and the side walls of the bowl. The extended transition can be a section around 45° to the bottom of the shell and can have a length of at least 8mm. Alternatively, the extended transition may be a long radius curved transition having a radius of, for example, more than 8 mm. This transition may be relatively larger than the one between the side walls and the underside, which may have a radius of less than 1 mm. The extended transition can be provided at only one end of the shell, for example closer to the handle, or it can be provided at both ends.
    [016] The shell can be of any suitable plastic material, most preferably from injection molded polypropylene.
    [017] The invention also relates to a package for powdered infant food comprising a tube defining a space containing product and a lid, an amount of powdered infant food within the space containing the product and a sealing membrane closing the space containing the product before use, the packaging further comprising a shell as defined above, placed on its upper side to the seal within the clearance space of the lid. The clearance space defined as the region between the seal and the cap may be less than 30 mm in height, preferably less than 25 mm in height or about 20 mm in height, as measured at the shell location. The shell is preferably sized to take advantage of this clearance space. Preferably, the width of the cup bulge is not more than 4 mm smaller than this gap space, more preferably not more than 3 mm smaller and preferably about 2 mm smaller. In other words, the height of the slack space exceeds the width of the bulge of the shell by no more than the amounts revealed. Under certain circumstances, the shell can completely and evenly fill the gap and rest against the sealing membrane. The sealing membrane can comprise a metal sheet or it can be a plastic-only sheet. A preferred material comprises outer layers of polypropylene with a barrier layer, for example, of EVOH laminate between them. The membrane may be removed completely prior to use or may comprise a perforation line defining an open region and an opening tab. The clearance space must be sufficient so that the shell does not damage the seal. In particular, it must be excluded that undesired leakage or perforation of the seal or any damage that could cause gas and oxygen leakage into the package should be excluded. It will be understood that one purpose of the seal is to prevent oxidation of the contents, which can lead to a reduced shelf life of the product.
    [018] The shell can be placed loosely in the clearance space. But preferably, the lid has a clamp on its underside to hold the handle of the ladle and the ladle is fixed by the clamp. When opening the lid, the shell can be removed from the clamp. It will be understood that the shell can be permanently formed with the cap or the clamp, for example by a tearable connection. In general, such connections may be less desirable due to the risk of particles falling into the space containing the product.
    [019] In a more preferred embodiment, the tube is a thermoformed tube of relatively thin plastic material having a peripheral wall extending to an upper edge defining the space containing the product, and wherein the lid is hinged to a rim external, fitted to the upper edge of the tube. The lid and the rim can be integrally formed together with a built-in hinge, eg by injection molding. The preferred materials for the cap and rim are polypropylene (PP), polyethylene (PE) and polyethylene terephthalate (PET) or combinations thereof, although one skilled in the art is familiar with the many alternatives that could provide similar engineering properties.
    [020] The package may have a generally square or rectangular outer profile with curved corners. The volume of the package can be between 500 ml and 3 liters, preferably about 2 liters and 800 ml, and the access opening preferably has a minimum dimension of at least 70 mm, more preferably about 100 mm and an area of at least 100 cm2. The overall length of the package can be between 150 mm and 250 mm, preferably about 185 mm. The width of the package can be between 100 mm and 150 mm, preferably about 120 mm. The packaging can be available in multiple heights according to the volume needed, ranging from 80 mm to 150 mm.
    [021] The invention further relates to a plurality of shells as described above, the shells being stackable by nesting their bulges and having different volumes by varying their depths while maintaining their identical width and length dimensions. Such a set of similar shells allows a standard package having a smaller clearance space to be implemented. According to the dosage requirements of the powder content, a ladle of the required volume can be added to the packaging. Shells can be color coded according to their volume.

    [027] Figure 5 shows the shell of Figure 4 in plan view;
    [028] Figure 6 shows a shell according to a third embodiment of the invention in perspective view; and
    [029] Figure 7 shows a shell according to a fourth embodiment of the invention in perspective view. DESCRIPTION OF ILLUSTRATIVE ACHIEVEMENTS
    [030] Figure 1 shows a perspective view of a package 1 for powdered infant food according to a first embodiment of the invention comprising a tube 2 defining a space containing the product 20 and a lid 12. A quantity of powdered infant food is placed within the space containing the product 20 and a sealing membrane 6 is shown in a partially removed condition. Cap 12 is hinged to an upper rim 10 which mechanically engages a lower rim 8, connected to tube 2. It will be appreciated that other cap assemblies may also be used in this context. Tube 2 is thermoformed of relatively thin polypropylene material and a sleeve 4 formed by cardboard supports around it.
    [031] A shell 42 is placed inside the lid 12 according to the present invention. The shell 42 has a handle portion 41, which is secured by a clamp 44 to the underside of the cap 12. The shell 42 is conveniently molded to be relatively narrow, allowing it to be placed on its side within the limited clearance space within. of cover 12. The handle part 41 has an open structure, which is convenient to prevent the accumulation of dust on the handle part 41 when in use. The lower rim 8 also incorporates a shell holder 50 and left and right side levelers 52. After use of the shell 42, it can be placed on the support 50. It will be appreciated that the support 50 has an elongated generally rectangular shape corresponding to that. of the shell 42 and orients the handle portion 41 of the shell 42 into a position where it can be easily removed by a user.
    [032] Figure 2 shows a cross section through the packaging of Figure 1, taken along line II-II with the lid closed, before removing the seal 6. As can be seen in this view, the seal 6 closes the space containing the product 20 and remains under the lower rim 8. The upper rim 10 and cover 12 define a clearance space 21 above the seal 6. The clearance space 21 has a minimum height h, measured at the center of the lid 12. As can be seen, the shell 42 is slightly narrower than the height h of the clearance space, so that it can be positioned without interfering with the seal 6. It will be appreciated that while the shell 12 is illustrated with its barrel 41 secured by the clamp. 44, can also simply be placed on seal 6 during the manufacturing process.
    [033] Figure 3 shows in greater detail the shell 42 of Figure 1, including an elongated opening 43 through the portion of the handle 41. The bulge 51 of the shell 42 has a width w that is relatively smaller than both its length l and its depth d. The bowl 51 has a generally rectangular shaped edge 39 with a width corresponding approximately to the width of the handle portion 41. The bowl 51 has parallel generally flat side walls 55 extending in the length direction and curved end walls 57 extending in the width direction. The walls 55, 57 of the bowl 51 taper to a slightly narrower closed underside 53 with a tapered angle of about 4.5° in both the width and length directions. This allows for convenient stacking of shells during manufacturing and transportation. On the end wall 57 opposite the handle portion 41, the cup 51 is in a small spout 49, which assists during stacking by preventing the cup of one shell from being inserted deeply into the cup of another shell.
    [034] The illustrated shell 42 has an edge 39 of 28 mm in length and 19 mm in width. The depth dimension of about 35 mm guarantees a shell volume of 11.5 ml. By varying only the depth dimension, different shell volumes can be provided while maintaining the same overall design. In particular, an 8 ml shell volume can be provided having a shell depth of 22 mm and a shell volume of 9.5 ml can have a depth dimension of 27 mm.
    [035] Figure 4 shows a shell 142 according to a preferred embodiment of the invention, in which similar aspects are provided as references preceded by 100. This shell 142 has a bulge 151 of similar shape to that of Figure 3. In particular, the depth d in this embodiment is at least 50% greater than the width w of the cup 151. The shell 142 differs from that of Figure 3 in that the lower side 153 of the cup 151 has a transition section 159 between the lower side 153 and a end wall 157 of bowl 151 closest to handle portion 141. Transition section 159 provides an extended transition that is relatively less abrupt than a transition between underside 153 and side walls 155 of bowl 151. These latter portions may form corners with radii of about 1 mm or less. The transition section 159 may have a length of more than 5 mm and be angled between 30° and 60° with respect to the underside 153.
    [036] According to one aspect of the invention, it has been found that narrow shells, ie those having a relatively narrow width compared to their depth and length directions, can be difficult to fill precisely. Accurate filling is important to ensure correct dosage. In some cases, air pockets can be shaped towards the underside of the bowl during filling, in particular at the corners between the underside and the end walls. By providing a transition section 159 as shown in Figure 4. Smoother and more accurate filling can be achieved without the formation of air pockets. It will be understood that other provisions may aid in filling and that the transition section may be curved or otherwise formed.
    [037] Figure 4 also illustrates the cable part 141 has a slightly different shape from that of Figure 3. In particular, the cable part is provided with two elongated openings 143, each of which is less than a width of the cable part. 141. Thus, it can be avoided that a cable from one shell is lodged in an opening of another shell during production and transport.
    [038] Figure 5 shows the shell 141 of Figure 4 in plan view. In this view, parallel side walls 155 and curved end walls 157 are more visible. In addition, the underside 153 of the bowl 151 can be seen with three small openings 161. These openings 161 are too small to allow the passage of the powdered product, but can pass air in order to avoid gaps during ladle filling and formation. vacuum on emptying.
    [039] Figure 6 shows an alternative shell 242 having a handle portion 241 similar to that of Figure 3 with an elongated opening 243. The shell 242 differs from the previous design of Figure 3 in that the cup 251 has a graduated structure. The edge 239 is the same width as the handle portion 241, but the cup 251 does not taper downward. Instead, it has a constant cross section with respect to a step 250 at a midpoint of the bulge and then a smaller constant cross section extending to the closed underside 253. The scoops 242 of this design can be stacked or nested. bulge 251 of a shell extending into the next shell above the step 250. As above, different volumes can be provided by varying the depth of the cup 251 with the step 250 preferably always being located at the midpoint.
    [040] Figure 7 shows yet another shell design 342 having a relatively simple structure of cup 351. In this design, the cable portion 341 is identical to Figure 3, but cup 351 has a constant cross section from edge 339 to the underside 353 and is not stackable. The person skilled in the art will understand that many other alternative shell configurations can be provided and that the shell design can be adapted to the design of the container itself.
    [041] Thus, the invention has been described with reference to certain embodiments discussed above. It will be appreciated that many modifications in addition to those described above can be made to the structures and techniques described herein without departing from the spirit and scope of the invention. Thus, although specific embodiments have been described, these are only examples and are not limiting to the scope of the invention.
