Description
Technical field
The utility model relate to a kind of adopt that moulding of plant fibres method is made, to comprise that the string of paper pulp (is called for short string; As follows) be bowl cover or the lid of material; Be applicable to bowl cover and lid that all adopt the various shapes of string making, especially cover on dixie cup or carton, the disposable plant fiber molding bowl cover that need to be combined with dixie cup or carton or lid goods (being referred to as below bowl cover), this moulding of plant fibres bowl cover goods can be circular can be also square or other abnormity.
Background technology
The manufacturing process of plant fibre moulding article is: string first passes through filtering molding in filtering molding device, the wet base of making articles, wet base is sent in the hot pressing die that is heated to uniform temperature, hot pressing die matched moulds also carries out hot-pressing drying sizing to wet base, make the plant fibre moulding article of various shapes, the manufacture method of this plant fibre moulding article is called " moulding of one-step method moulding of plant fibres " or claims " moulding of wetpressing moulding of plant fibres "; Another kind method is that wet base oven dry or air dry is dry, wet base is dried or air dry arrives certain mass dryness fraction, again goods are sent in the hot pressing shaping mould that is heated to uniform temperature and carried out hot pressing shaping, and further dry, this is plant fibre moulding article manufacture method " moulding of two step method moulding of plant fibres " or claims " moulding of dry pressing moulding of plant fibres ".Moulding of plant fibres bowl cover, can adopt these two kinds of methods to be made.These two kinds of methods all need " hot pressing mold " and " hot pressing bed die " to carry out upper and lower matched moulds wet base to be carried out hot-pressing drying sizing or the goods after drying are carried out to hot pressing shaping, also need " hot pressing mold " and " hot pressing bed die " carry out die sinking and take out goods.Therefore the structure of moulding of plant fibres bowl cover goods must be can the demoulding without the concavo-convex structure in side, the only in this way goods demoulding smoothly, this is industry general knowledge.
As shown in Figure 1, the upper shed edge of dixie cup is that arc structure (is called for short " arcuation peristoma ", as follows), in order to make bowl cover and cup close contact, it is so-called arcuation " groove " that bowl cover is also made the arc structure similar to " the arcuation peristoma " of dixie cup to " arcuation peristoma " close contact part of dixie cup.Only in this way, arcuation " groove " and " arcuation peristoma " match and just can play good sealing effectiveness.Therefore, bowl cover and cup close contact must be accomplished: should seal locking again.
For realizing this two functions, current published cup lid structure all attempts to produce the arcuation " groove " that can seal like this and can be locking.For example, " the disposable paper bowl cover " that the patent No. is ZL200920053929.5, alleged " groove " and Chinese Patent Application No.: 200910157668.6 so-called " barb grooves ".Cup lid structure described in these two patents is same structure, from they diagram and text description all clearly tell us, this bowl cover is that side direction is protruded with " groove that cup opening part flange fastens ", the goods that have " side direction is concavo-convex " structure are with after mould molding, goods can be stuck on mould, be difficult to and mould separating, in industry, be referred to as " demoulding " difficulty.Patent 200920053929.5 is to adopt following methods to make: after string (paper pulp) is molded, after thermocompression forming or hot pressing shaping, then through the method for secondary operations, suppress " groove " of one ring bodies.But there is following problem in " groove " of ring bodies or ring-type " barb groove ": one, the disclosed moulding of plant fibres cup lid structure of patent 200910157668.6 and manufacture method can be found, on bowl cover border, process after ring-type " barb groove ", when goods are taken out in die sinking, ring-type on bowl cover border " barb groove " can be stuck in (" barb groove " blocked by the holding groove of bed die) on bed die, because bed die is integral structure, want bowl cover goods to take out from bed die, it is bowl cover demoulding from bed die, must force to eject with so-called " ejection block ", could depart from counterdie, forced stripper mechanism easily draws bad goods, two, can there is internal stress distortion in this whole ring-type " barb groove " out of secondary operations of carrying out after being dried, and this ring-type " barb groove " has been difficult to an accurate size, and cup peristoma very difficult and ring-type is accomplished real close contact, three, ring-type " barb groove " is combined and is made by its so-called segmentation " moulding bar ", and therefore, ring-type " barb groove " tends to stay seam in process of production, and circular-arc " groove " sealing effectiveness is reduced, four, annular ditch groove is the formation that is squeezed of bowl cover circumference, and the bowl cover after being squeezed has certain resilience after die sinking, is difficult to reach accurate arcuation " groove " and matches with the arcuation peristoma of cup.The problem of existing ring-type " barb groove " is to go out " arcuation groove " complete, good sealing effect one by disposal molding.
Again for example: application number is: 201220410099.9, name is called " a kind of paper pulp bowl cover with buckle " and application number is: 201310359135, name is called the patent of " two-sided paper mould bowl cover and manufacture method thereof without reticulate pattern ", alleged " buckle " is also " groove " that has " side direction is concavo-convex ", from " Fig. 3 " shown in these two patents, can clearly be seen that, " buckle " is arcuation, and is protruding laterally.Therefore also there is " demoulding " difficult problem in described " buckle "; This being called " buckle " " groove " is discontinuous, and with the edge of opening " clamping " of cup, and the edge of opening of cup is continuous annular structure, so discontinuous " buckle " cannot form sealing with the edge of opening of the cup of continuous annular.From position and the shape of this " buckle ", it can also be seen that, so-called " buckle " is exactly " the barb groove " described in patent ZL200920053929.5 and the application number patent that is 200910157668.6, difference be this so-called " buckle " be discontinuous, can be referred to as discontinuous " barb groove ", this discontinuous " buckle " is that " arcuation peristoma " matches with continuous dixie cup edge of opening, cannot realize sealing function.So both having there is demoulding difficult problem in the bowl cover of this band " buckle ", cannot reach sealing function aborning again, therefore without practical value.
Because of a little, if " groove " of bowl cover is reasonable in design, when bowl cover is produced, the demoulding is just easy, and provides possibility for realizing automated production; When bowl cover is used, can play good sealing effectiveness.
