Abstract

The utility model provides a cover structure which comprises an upper cover and a lower cover; the edge of the upper cover is encapsulated and fixed with the edge of the lower cover through a disposable rotary-fracture wrapping edge. The wrapping edge also comprises a pull ring, and the connection part of the pull ring and the wrapping edge is provided with a crease, so the wrapping edge can be torn down by the pull ring from the crease. The lower cover forms an accommodation cavity, and an auxiliary pull ring is arranged on the bottom surface inside the accommodation cavity; the lower cover can be opened easily by the auxiliary pull ring. The cover structure has good sealing effect, occupies no space and is easy to open, and can be used repeatedly.

Description

A kind of lid structure

[technical field]

The utility model relates to a kind of lid structure, but particularly a kind of good seal, is easy to open and the lid structure of long-term use, can be used for the sealing of various bottleneck, packing jar mouthful.

[background technology]

Traditional lid mostly is single layer structure, and as the bottle cap of ordinary beer bottle, it is pressed on the bottleneck with the pressure bottle capper, needs during use bottle cap is levered up by force, and bottle cap promptly wrecks, thereby can't continue to use.The lid that also has a kind of bottle cap or packing jar in addition, cooperate by an outside thread that covers set negative thread and bottleneck or packing jar mouthful and to screw, after opening, this lid structure also can continue to use, but the sealing effectiveness of follow-up use is not ideal enough, and bottleneck or a packing jar mouth need have higher projection in order to machining screw as screwing portion, for the packing jar of larger volume, take up room very much especially like this, simultaneously very not attractive in appearance yet.

[summary of the invention]

The technical problems to be solved in the utility model is to provide a kind of bottle cap, its good sealing effect, but do not take up room and be easy to open and the lid structure of long-term use.

The utility model is that this will realize, a kind of lid structure is characterized in that: it comprises a loam cake, a lower cover, and the edge of described loam cake and lower cover is fixing with the bound edge encapsulation of disposable rotation fracture.

Described bound edge also comprises a draw ring, and this draw ring is extended to the lid center by the arbitrary position of bound edge.

The connecting portion of described bound edge and draw ring is provided with a tear mark, and tear mark is extended in bound edge by the edge of connecting portion.

Described loam cake integral body is schistose texture, and central authorities are provided with an annular groove, and this annular groove is corresponding with the shape of described draw ring.

The vertical section of described lower cover is flanged U-shaped, and central authorities form a containing cavity, and the outer wall lower end of this containing cavity from top to bottom forms the conical surface of convergent.

The containing cavity inner bottom surface of described lower cover is provided with an auxiliary draw ring, and this auxiliary draw ring is connected as a single entity by connecting portion and containing cavity inner bottom surface.

Described loam cake and bound edge are that metallic gets, and described lower cover is that plastics make.

The utlity model has following beneficial effect: it adopts two-layer setting, and most of recessed being embedded in the packing jar of lower cover do not take up room, and is convenient to pack stacking of jar; Loam cake adopts schistose texture and packing jar identical material, makes whole packing jar unified appearance attractive in appearance during encapsulation; When first unlatching, with draw ring bound edge is torn up, loam cake just drops out, and by auxiliary draw ring lower cover is extracted to get final product again.Follow-up use only need lower cover compressed or pull up but can, its sealing effectiveness is better, applicable to various bottle and packing jar, is particularly useful for packing jar.

[description of drawings]

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

Fig. 1 is the decomposing schematic representation of the utility model lid structure.

Fig. 2 is the assembled state scheme drawing of the utility model lid structure.

Fig. 3 is the cross-sectional schematic of the utility model lid structure.

[specific embodiment]

See also Fig. 1 and shown in Figure 3, a kind of lid structure of the present utility model, it comprises a loam cake 1, a lower cover 2 and a bound edge 3, it is used to cover at packing jar 4.

See also Fig. 1 and Fig. 3, described loam cake 1 integral body gets for schistose texture and by metallic, and central authorities are provided with an annular groove 11.

See also Fig. 1 to Fig. 3, described lower cover 2 makes for plastics, the vertical section of described lower cover 2 is the U-shaped of flanged pin 21, central authorities form a containing cavity 22, the outer wall lower end of this containing cavity 22 from top to bottom forms the conical surface 221 of convergent, bottom surface 222 in the containing cavity 22 is installed with an auxiliary draw ring 23, and this auxiliary draw ring 23 is connected as a single entity by the bottom surface 222 in a junction 232 and the containing cavity 22.

Described bound edge 3 is made for thin metal, and it comprises a draw ring 31, and this draw ring 31 is extended by the center position of the arbitrary position of bound edge to lid, and the shape of this draw ring 31 is corresponding with the annular groove 11 of loam cake 1; Described bound edge 3 is provided with a tear mark 33 with the connecting portion 32 of draw ring 31, and tear mark 33 is extended in bound edge 3 by the edge of connecting portion 32; Come as long as a pull-up draw ring 31 firmly slightly, bound edge 3 promptly rupture gradually from the tear mark 33 of connecting portion 32, therefore the bound edge 3 of can tearing be the bound edge that disposable rotation is ruptured.

During encapsulation described loam cake 1 is stacked in the top of lower cover 2, and with the edge of loam cake 1, the flange 21 of lower cover 2 and opening 41 edges of packing jar 4, fixing with bound edge 3 encapsulation, and allow the draw ring 31 of bound edge 3 place in the annular groove 11 of loam cake 1, smooth to keep covering body structure surface.Lower cover 2 most of recessed being embedded in the packing jar 4 after packaged do not take up room, and are convenient to pack jar 4 stack;

When unpacking for the first time jars 4 the time, earlier with draw ring 31 pull-ups, the bound edge 3 of tearing, loam cake 1 just drops out, and lower cover 2 also separates with the opening 41 of packing jars 4, and at this moment, draw ring 23 is assisted in pull-up, lower cover 2 is pulled out get final product, and is convenient and practical.
