Abstract

The utility model relates to an insulated cup lid, which comprises a lid core and a plastic lid and is characterized in that the top of the lid core is provided with a polygonal fastening pin; a clearance is reserved among every two adjacent edges of the polygonal fastening pin; the inner top of the plastic lid is provided with a polygonal fastening position matched with the polygonal fastening pin; and the lid core and the plastic lid are vertically fastened together into a whole by fastening teeth on the polygonal fastening pin and fastening slots on the polygonal fastening position. The insulated cup lid has the advantages that when in use, convolutional force can be scattered to a plurality of directions, thus preventing the lid core and the plastic lid from falling off and avoiding spinning in the circumferential direction; furthermore, the fastening structure has fewer parts, simple assembly and firmness and durability; and in addition, a silica gel ring arranged can play better water sealing and thermal insulation effects.

Description

The thermos cup lid

Technical field

The utility model relates to a kind of lid, particularly relates to a kind of lid of thermos cup.

Background technology

In daily life, existing bowl cover generally all adopts the structure of more complicated in order to reach good water shutoff and heat insulation effect.As China Patent No. is to disclose a kind of " lid " in 200620100996.4, comprise lid and enclosing cover, it is characterized in that: be articulated with a spanner on the end face of lid, the lower end mask of spanner possesses two highly not high table tops, seamlessly transits between two table tops; Also be provided with plunger and spring in the lid, plunger top is the bulb shape, with the lower surface of spanner to conflict, the plunger middle-end is a joint pin, bottom shape is consistent with the lid cross section, and matches with sealing ring on the lid.Because complex structure, the parts of this class bowl cover are more, assemble also more loaded down with trivial detailsly, increased production cost, be unfavorable for applying; And the rotating force of in use getting when covering is excessive, also can cause lid and lid shell to come off.

Summary of the invention

The purpose of this utility model provides a kind of thermos cup lid of simple in structure, firm and durable.

For this reason, the technical solution of the utility model is: the thermos cup lid, and comprise cover core, mould lid, it is characterized in that: the cover core top is provided with polygon and buckles pin, has the gap between per two adjacent edges of polygon button pin; Mould and cover inner top and be provided with the polygon button bit that matches with described polygon button pin, cover core and mould lid and buckle buckle teeth on the pin and the catching groove on the polygon button bit by polygon, snapping gets up to become one up and down.

As further improvement, described polygon button pin and polygon button bit are octagon button pin and octagon button bit.

In addition, cover core covers the middle silica gel circle that also is provided with moulding.

Assembling of the present utility model is earlier the silica gel snare to be moulded outside the polygon button bit that cover inner top, again with cover core with mould lid and buckle buckle teeth on the pin and the catching groove on the polygon button bit by polygon, snapping gets up to become one up and down, and is non-dismountable.

Advantage of the present utility model is: this thermos cup lid adopts technique scheme, and its power of in use circling round can be dispersed to a plurality of directions, makes cover core and mould to cover difficult drop-off and also can not spin in a circumferential direction; And this fastening structure parts are few, the assembling simple, firm and durable; Add the silica gel circle that is provided with, can play better water shutoff, heat insulation effect.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

Referring to accompanying drawing, present embodiment comprises cover core 3, moulds and cover 2.Cover core 3 and moulding covers 2 and becomes one by octagon fastening device snapping, is exactly that cover core 3 tops are provided with octagon and buckle pin 5, has gap 7 between per two adjacent edges of octagon button pin 5; Mould and cover 2 inner tops and establish the octagon button bit 4 that cooperates with described octagon button pin 5; Sky is dragged in the outside, lower end, every limit of octagon button pin 5, and the outside, upper end is an inclined downward, molds the buckle teeth 8 of tangent plane for " 7 " font; Sky is dragged in the inboard, upper end, every limit of octagon button bit 4, molds tangent plane for falling the catching groove 9 of " 7 " font; Cover core 3 and moulding covers 2 snapping and buckles into catching groove 9 on the octagon button bit 4 with regard to the elasticity of utilizing octagon to buckle buckle teeth 8 on the pin 5.

In addition, cover core 3 covers 2 middle silica gel circles 1 in addition with moulding.

Assembling of the present utility model is silica gel circle 1 to be enclosed within to mould octagon button bit 4 outsides of cover 2 inner tops earlier, again cover core 3 is covered 2 and buckles buckle teeth 8 on the pin 5 and the catching groove 9 on the octagon button bit 4 by octagon with moulding, and snapping gets up to become one up and down, and is non-dismountable.

Claims
