The area of described gangway is at least about 50cm 2.
In one embodiment, the present invention relates to the packaging for Powdered infant nutriment.In this packaging, importantly, foreign matter does not enter in this packaging and to powder and pollutes.On the other hand, this packaging needs to open repeatedly.
Usual use Metering spoon obtains Powdered baby's milk foods from container.Metering spoon is often included in packaging.Therefore, in order to suitably obtain powder from container, gangway should be large as far as possible.
All these demands seem to be difficult to be incorporated into together in single container.But, such as, provide the most straightforward procedure of carrying out excellent sealing to container to be make gangway little as far as possible.In addition, sealing is realized by (partly) permanent type closing appliance usually preferably.
But cover of the present invention makes it to become possibility.The invention provides the cover for container of gangway, this gangway is enough large to make content (such as, powder) by Sheng outside container, and can have the sealing effectively reducing foreign matter and enter.It is unexpected that discovery be, the cover with vomitoria of the present invention can be closed repeatedly and keep excellent sealing.
Cover of the present invention provides excellent sealing, its container preventing from foreign matter from entering this cover covering., the lid of cover needs repeatedly open continually and close every day, and provides excellent sealing after frequent use.Preferably, sealing is realized in an easy manner.In fact, found in embodiments, the crack force of about 2-5N is acceptable.For seal force, in embodiments, the power of about 6-15N is acceptable.
The container covered due to cover needs to be discardable, and therefore cover is preferably cheap, thus produces in a large number and provide minimal waste.In addition, it is advantageous that be easy to process cover in process of production and in the production process of complete container.In addition, if the contents of packaging are moisture absorptions, then excellent sealing is especially expected.The air (having high moisture content) better closed between can reducing inside and outside packaging exchanges, thus reduces the formation of block in hygroscopic material (such as baby milk).Therefore, the present invention is particularly useful for storing in tropical climate environment for baby milk.
Cover of the present invention can be used for the container such as with cardboard wall, but is not limited only to this use.Usually, this cardboard wall is coated with or scribbles one or more layers sealing layer, thus seals to make it from environmental concerns to receiving thing in container.The embodiment of this packaging is disclosed in WO2005075314 and WO2007142522 of applicant.Be for the significant jurisdiction of courts for this, these files are incorporated to herein by reference, as it is documented in herein completely.
Cover is especially applicable to using together with the container for storage powder.In fact, it is suitable for storing hygroscopic powder, the specifically food of similar baby milk well.Manually opened and closedly preferably need very limited effort and/or strength.Preferably, lid can come manually opened by a hand.This is especially be correlated with for baby milk packaging, because mother preferably can open and enclose when having baby in arms.
In order to avoid hand directly contacts with content, lid is provided preferably with clamper, for clamping and keeping Metering spoon or spoon.This further restricts the selection of size.
Therefore the size of the handle of this spoon is limited.On the other hand, this also may limit the size of packing container.In embodiments, the handle long enough of spoon, with the bottom making people can touch container.In embodiments, described circulating type first flange has: the first periphery, near described connecting portion; And second periphery, near the edge of described flange, the edge of described flange is positioned at the end away from described connecting portion of described flange, and the second periphery of described circulating type first flange is greater than its first periphery, and described lid has: the first inside circumference, near described lid; And second inside circumference, near the edge of described lid flanges, described second inside circumference of described lid is less than described first periphery on the edge near described lid flanges, the periphery of described lid flanges and the periphery of described first flange are applicable to mutually, to allow described lid to close in a sealing fashion on described first flange of described connecting portion, and the lid flanges of described lid is around described first flange.This permits easily closed and unlatching, especially for routine use.In addition, by sealing lid flanges around the first flange, easier release cap parts after molding.
In embodiments, the first flange be positioned on connecting portion provides snap lock to seal together with lid flanges.Corresponding lid flanges (sealing band (bead) on lid) is thus interlocked with one another, and such first flange carries out suitable seal interference.Sealing is interfered can provide suitable sealing load, enter or leave container, or it can be implemented to ensure that maximum clearance is enough little of to prevent foreign matter from entering container to prevent moisture.These features also allow by using usual engineering plastics to provide sealing property, and can help avoid the extra cost of the elastomeric material of two component overmoulding.
In addition, in embodiments, flange and lid flanges (can also be hereinafter referred to as chimney (chimney) and engaging sealing band feature) can exchange to play same mechanism, and/or two " chimney " features can instead use.It should be noted, chimney feature can have similar curvature on inner and outer wall, this allows chimney feature to be injected shaping, make that therefore this feature can allow to cool faster when peeling off from mould without when special floating core, lower cycle time and therefore allow lower cost.In addition, for considerable larger diameter hole, the layout of these seal feature allows strong engaging sealing property.
In addition, the layout of flange or engaging seal feature can be adjusted to allow sufficient sealing property, suitable crack force and suitable seal force.And, when packaging is subject to external force interference, seals by engaging the confining force provided and prevent cover part ground or fully open or seem partly to open.The concrete curvature of flange, angle and processing geometry (undercutgeometry) (chimney and sealing band feature) and assembling thereof are interfered can be adjusted to change sealing load, crack force and seal force like that according to what may need.
In embodiments, the area of gangway is at least about 60cm 2.This allows the discrepancy better of hand.In embodiments, the area of gangway is at least about 75cm 2.
In embodiments, the area of gangway is at least about 250cm 2.Therefore, can be easy to come in and go out for the hand of adult provides, and still allow to be closed with making sealing of lid by simple action.In embodiments, the area of gangway is at least about 200cm 2.These upper and lower bounds the easy discrepancy of staff, fully rigidity, good close and provide can keep in the lid and provide compromise between the possibility of the spoon that can reach bottom container assemblies or spoon.
In embodiments of the present invention, described first flange defines described gangway.This can increase the rigidity of cover further.
In embodiments, described first flange launches away from described gangway or opens, thus the periphery of described first flange is increased.
In embodiments, described circulating type first flange is near the described edge of described first flange or thickening around ground in the neighboring of described circulating type first flange along place described first flange described.Alternatively, or additionally, the inside circumference of lid flanges is near described edge or described thickening along place.
In embodiments, described second inside circumference of described lid flanges is less by about 2% to 7% than described first periphery of described connecting portion.Especially, when lid flanges is made up of thermoplastic material, find to this provide excellent sealing but still keep enough easily opening.
In embodiments, described gangway is substantially circular or substantially elliptic.This in most of the cases can provide moisture seal.In some applications, with regard to seal degree, even the rectangular aperture with fillet also may be acceptable.This kind of shape allows excellent sealing.In order to provide moisture seal to hygroscopic powder, in gangway or the first flange and lid, preferably avoid large (with regard to discussed size) straight parts.
In embodiments, the area of described gangway is at least 50% of the area of connecting portion.This is assigned with sufficient space to allow a hand to send spoon to obtain content.On the other hand, this allows appropriate seal, and allows suitable spoon or spoon to be clamped in inside lid.
In embodiments, the area of described gangway is the about 60-70% of the area of connecting portion.This is seemingly suitable compromise.
In embodiments, the internal diameter of described gangway is about 9 to 13cm.In embodiments, the diameter of connecting portion is at least 10 to 13cm.These sizes provide excellent sealing and the capacity sufficient of container.
