Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is described in further detail, but the utility model be not limited to
Lower embodiment.
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5, in the cross section figure of the moulding of plant fibres cup lid, cup lid edge to cup lid
The boss side straight flange 7 for being followed successively by the cup lid side straight flange 3, arcuation groove 2 and the cup lid boss 5 that are smoothly connected at center, cup lid is convex
The top surface of platform can be fabricated to various shape (such as inclined-plane, aperture) as needed;This and existing moulding of plant fibres cup lid
Structure it is similar.
The improvement of the utility model is that a ring plain 6 is being set up between arcuation groove 2 and boss side straight flange 7;Therefore
Moulding of plant fibres cup lid described in the utility model contains arcuation groove 2, cup lid side straight flange 3, cup lid boss 5, cup lid boss
5 side is boss side straight flange 7, and cricoid arcuation groove 2 is located at the top of cup lid side straight flange 3.It is set in the bottom of cup lid boss 5
Vertical ring plain 6, as shown in Figure 3, Figure 4, ring plain 6 are that a circular plane (is parallel to level as seen from the figure
Face), between arcuation groove 2 and cup lid boss 5, i.e., between the bottom of boss side straight flange 7 and arcuation groove 2;Arcuation groove 2
The connection of connection and boss side straight flange 7 and ring plain 6 with ring plain 6 can use arc transition.
When producing the moulding of plant fibres cup lid, moulding of plant fibres cup lid break away from moulds after thermocompression forming is planted
After fibres molding cup lid leaves thermocompression forming mold, it can deform and shrink, the moulding of plant fibres cup lid after cooling
Last size depend primarily on it is cooling after the shrinkage of material add the deflection of 2 curved surface of arcuation groove, because of the contraction of material
Very little, either the deflection very little of the arc length of plane length or width or curved surface are measured, but the arc shape of arcuation groove 2 becomes
Shape is bigger, i.e., the opening of Curved arc can shrink and become smaller.
As shown in figure 5, the arc shape because of arcuation groove 2 deforms, the opening L of cyclic annular arcuation groove 2 in curved surface, which is shunk, to be become
It is small, and ring plain 6 is plane, the shrinkage very little of material, so the shrinkage of the ring width W of ring plain 6 is very
It is small.Therefore, ring plain 6 is set up, and may establish that junction (and the arcuation groove 2 of arcuation groove 2 and ring plain 6
Opening inner side, also referred to as groove face connection ring 8) geometric position from the cup lid center line and size be basically unchanged, then arcuation groove 2
Opening L become smaller, can only be that arcuation groove 2 and the arc near 3 junction of cup lid side straight flange are close to cup lid center line, thus band
Dynamic cup lid side straight flange 3 slopes inwardly (as shown in Figure 7).
Again because dixie cup ring-type peristoma 1 is an annulus, there is certain anti-pressure ability (as shown in Figure 6, Figure 7);Work as dixie cup
When cyclic annular peristoma 1 slides entirely over the opening of arcuation groove 2 of cup lid, the opening that arcuation groove 2 reduces can be opened and enter arc
In shape groove 2, ring plain 6 is made to withstand dixie cup ring-type peristoma 1, and dixie cup ring-type peristoma 1 can push arcuation groove 2 and dixie cup
Cyclic annular 1 contact portion of peristoma is turned out around groove face connection ring 8, is further resulted in cup lid side straight flange 3 tiltedly.If arcuation groove
2 depth H is sufficiently large, and oblique effect is then more apparent in cup lid side straight flange 3;In addition, if the depth of arcuation groove 2 is deep enough, arc
Shape groove 2 itself also has clamping action to dixie cup ring-type peristoma 1.In the inside of paper cup rim, ring plain 6 withstands paper cup ring again
Shape peristoma 1, in this way, the opening two sides that arcuation groove 2 reduces can block dixie cup ring-type peristoma 1, to prevent the ring-type of cup body
Peristoma is skidded off from " the arcuation groove " of cup lid.If setting a pingbian 4 in cup lid opening, when arcuation groove 2 reduces
Opening two sides when blocking dixie cup ring-type peristoma 1, arcuation (when such as hand takes cup lid) can be further prevented when there is external force
The open outer side that groove 2 reduces expands outwardly, and plays reinforcement effect.
As shown in fig. 7, this form the naturally clamping of " overhead kick " and arcuation groove 2 itself to dixie cup ring-type peristoma 1
Effect, has reached the locking and sealing purpose between the arcuation groove 2 of moulding of plant fibres cup lid and dixie cup ring-type peristoma 1.Through
Many experiments, if the ring width W of ring plain 6 is greater than 1 millimeter and less than 20 millimeters, locking and sealing effect is preferable;Arcuation ditch
The top of slot 2 is more than or equal to the top arc radius R of arcuation groove 2 with 6 distance H of ring plain, and locking and sealing effect is also more preferable.
