The specific embodiment

Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Referring to figs. 1 through Fig. 9, an embodiment of plastic closure of the present utility model is proposed, this plastic closure is used to be fastened on the vessel port of adaptive vessel, can be applicable to as in the containers such as uncovered cup, crisper, seal box.This plastic closure comprise lid 10 and evenly be arranged at least three of lid 10 peripheries can upper and lower folding button 20, lid 10 passes through the integrated through injection molding moulding to 20 with button.At button 20 internal faces are provided with and are used for the fastener that engages with groove on the vessel outside wall surface, this fastener is that a phase make-up is 20 intilted oblique buttons 200, on this oblique button 200, lower surface is the phase make-up 20 intilted level and smooth dip plane, tiltedly button 200 phase make-ups 20 intilted angles of inclination less than 65 °, then be bent to 20 downwards when vertical with groove on the vessel at button, tiltedly the groove on the button 200 relative vessels tilts, tiltedly the angle of inclination of the groove on the button 200 relative vessels is for oblique button 200 and detain the angle of inclination between 20 is added 90 °, the angle of inclination of then tiltedly detaining the groove on the 200 relative vessels is less than 155 ° and greater than 90 °, tiltedly detains 200 top ends and can insert in the groove on the vessel; And the size and the recess width on the vessel of tiltedly detaining 200 top ends are adaptive, then tiltedly detain 200 top ends and can directly snap in the groove on the vessel, thereby seal cover cap is sealingly fastened on the vessel.The utility model design-calculated fastener simple in structure need not need design overhead structure as original fastener, thereby need not to use oblique top to make overhead structure, can simplify mould structure, effectively improves the depanning shaping speed, enhances productivity; And when depanning, need not to use oblique top to eject mould.

Be provided with a nest 100 at lid 10 inner faces, this nest 100 is adaptive with the internal diameter of vessel port, is used for inserting vessel port and positions; On nest 100, evenly be provided with some thimble positions 101 that are used for for the thimble overhead, thereby at seal cover cap after injection mo(u)lding, can use the depanning of thimble overhead: thimble is evenly distributed on the thimble position 101 of nest 100, then the seal cover cap plastic of moulding is ejected and get final product, need not the staff pickup, can save manpower, enhance productivity, reduce production costs, avoid the generation of accident on duty in the production process.And after depanning, button is more attractive in appearance 20 outward appearance, can solve because of there is die joint in passing production method, the problem that causes the follow-up finishing of mould to cooperate.

In the present embodiment tiltedly button 200 phase make-ups be 20 intilted angles of inclination 57 °, be the optimum tilt angle, be beneficial to oblique button 200 and snap in or deviate from the groove of vessel.

Tiltedly the cross-sectional plane of button 200 is top width than the little triangle of bottom width or trapezoidal, and its top ends is taper comparatively, is beneficial to snap in the groove; Its end portion is comparatively generous, thereby is not easy to fracture.

Button be provided with on 20 outside wall surface one with tiltedly detain the cooresponding recess groove 210 of 200 shapes, tiltedly button 200 is the inside recessed formation of 20 outside wall surface from button, when the inside recessed formation of 20 outside wall surface tiltedly being detained 200 from button, at button 20 outside wall surface have been formed and the cooresponding recess groove 210 of oblique button 200 shapes, this design can make the thickness of detaining 20 reduce, and thickness is even, detain each position thickness unanimity 20, thereby solve because of detaining the big shrink problem that causes of 20 thickness, improve the yield rate of die production, make full use of material, reduce unnecessary waste.

Lid 10 and button be connected with between 20 one can upper and lower bending thin slice 120, the thickness of thin slice 120 is even, central authorities at thin slice 120 are provided with a rectangular gap slot 121, be used to reduce the concentrated stress of thin slice 120, prevent that thin slice 120 from producing endurance crack because of repeatedly bending, can improve the Occupation coefficient of thin slice 120, thereby improve the quality of seal cover cap.

Be provided with a ring cover groove 110 in the junction of lid 10 inner faces and vessel port, this lid groove 110 is equipped with the seal ring 111 that a usefulness glue clings around nest 100 peripheral settings in lid groove 110, be used to strengthen the leak tightness of vessel and seal cover cap.

The shape of lid 10 can be polygon or circle, and lid 10 shapes in the present embodiment are made as oblong.

Button can be oblong or arc to 20 shape, and the button in the present embodiment is made as arc to 20.

To shown in Figure 9, for the utility model seal cover cap is fastened on running condition figure on the vessel 30, be provided with the groove 300 that is provided with around vessel port as Fig. 7 on vessel 30, groove 300 openings are used for engaging with oblique button 200 on the seal cover cap down.When seal cover cap and vessel 30 fastened, the oblique button 200 on the seal cover cap was buckled in the groove 300 on the vessel 30, links closely mutually; Seal ring 111 on the seal cover cap strengthens the leak tightness between seal cover cap and the vessel 30.

The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model specification sheets and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
