Description
Technical field
The present invention relates to a kind of container, this container need be invaded moisture has the bounded system of high block.
More particularly, the present invention does not relate to the bounded system that a kind of container that is made of metal is used uniquely, and this bounded system should have high moisture barrier property.
Background technology
Some dry products are extremely sensitive for the deterioration that causes because of the absorption moisture.For example, milk powder and dispensed food for baby comprise labile vitamin, if reach too high moisture level, these vitamins are deterioration fast.As another more extreme example, the applicant has been found that the nutrition/flavored milk additive of some type is extremely responsive for moisture, if the weight increase that causes because of the absorption moisture equals or exceeds 2%, they just can not use.
Owing to these reasons, traditionally before with still be packaged in this series products in the leak free metal can now.
For within easy reach, have high resealability and have tamper-evident evidence, metal can generally includes bounded system, this bounded system is called as " additional annular part and paper tinsel " (tagger ring and foil) " TRF " system in this area.
Traditional T RF system comprises first parts of " annular element " form.This annular element is suitable for making the known double-seam process seal in field to tank body through jar, and according to known technology, this annular element comprises that use flows into joint seal agent (flowed-in seaming sealant).Aquaseal normally provides the rubber constituent of the sealing characteristics of expectation when compression.Annular element limits the controlled central opening of internal diameter, and this central opening has roughly vertical wall, and this wall has inside side cut towards container, and second parts can form the interference sealing with this central opening.
Traditional T RF system also comprises second parts of " prying open the formula connector " (lever plug) form.The formula connector of prying open comprises tabular surface and flange; Tabular surface is connected on the vertical wall of column roughly; Vertically the external diameter of wall is suitable for forming interference fit with the opening of annular element; Flange extends the inside to prevent that connector is pulled to jar from vertical wall, and for example allows to use suitable utensil such as spoon that connector is prized from jar.
For the purpose of this specification sheets; Interference sealing is understood that to enter into the sealing that the opening of the controlled diameter of another parts (annular element) provides through parts (connector) that force controlled diameter, and wherein the diameter of connector is more than or equal to the diameter of the opening of annular element.
Traditional T RF system also comprises the 3rd parts of foil seal form.Foil seal is positioned at a jar inside, and the seam flange from annular element extends across whole end.This foil seal is maintained in the seam flange, and when sealing, is encapsulated in the double seam.Keeping the method for foil seal can be in the side cut of foil seal, to apply joint sealers.
In use, foil seal provides initial sealing.When opening, progressively to use between the common stage of exhaustion of product in (can be several weeks or some months in some families), the interference sealing between annular element and the connector provides enough moisture barrier property, to keep product quality.
In optional bounded system, the paper tinsel that is encapsulated in the seam is replaced by the paper tinsel on the par that is heat sealed to annular element.This has reduced the use amount of paper tinsel, has therefore directly reduced the cost of paper tinsel.Yet, can thermosealed system cause cost to increase owing to using.
Because intensity and formability, paper tinsel is normally made of aluminum.Aluminium foil is expensive.In addition, the customer finds after removing connector, need puncture and remove very inconvenience of paper tinsel.And there is injury customer's danger in the side cut of the paper tinsel that punctures.Particularly attempt to come under the situation of cost-cutting through the thickness that reduces paper tinsel all the more so.In addition,, do not hope in cylinder of steel, to use aluminium foil,, when reclaiming the ladle dress, will remove as slag because aluminium is a kind of impurity as sealing member along with the raising of environmental consciousness.
For above-mentioned reasons, need a kind of TRF system that does not use aluminium foil.
In the past, the applicant thought that the moisture barrier properties of the connector of steel-steel and annular element assembly was not enough to the lasting as ground long term storage sensitive product in wet environment.This causes the applicant to continue to use traditional T RF bounded system for this product.
Above-mentioned explanation not will be understood that it is the common practise at Australia or elsewhere.
Summary of the invention
Now, the applicant has been found that the shallow layer that between the connector of TRF system and annular element, uses extensible sealing substance can increase to the moisture barrier property of system and does not use independent sealed foil just can realize the degree of very long pot-life.
Therefore, the bounded system that the present invention provides a kind of container to use, this container needs high moisture barrier property, and bounded system comprises: annular element, it limits opening; Connector, it is used to seal opening; And extending leakproofing material, it is used for contact plunger and annular element, and when bounded system was in detent position, this extending leakproofing material formed sealing between annular element and connector.
