Abstract

The utility model discloses a closing cap subassembly of container, the container have the receiving port, the closing cap subassembly including firmly hold female lid, the encapsulation on female lid on the receiving port, female lid has the oral area corresponding to the receiving port, the sub-lid constitute to the flange that the peripheral direction extends the formation by the upper end border that the longitudinal section is the U-shaped insertion portion and by the insertion portion, the outer peripheral face of insertion portion closely cooperates with the inner wall of oral area mutually, the flange withhold on female at least part upper surface of covering. The cover sealing component has the advantages of less material consumption and convenient use.

Description

A kind of closure assemblies of container

Technical field

The utility model relates to a kind of closure assemblies of container, particularly relates to a kind of closure assemblies of mental package jar.

Background technology

At present, container upper port at can body as metal can is connected with the female lid of a circle, covers encapsulation lid mother again, forms the sealing to entire container.In the prior art, female lid is generally annular arrangement, and sub-lid is circular flat board, and in order to make the primary and secondary lid to be sealed and matched mutually, the periphery that covers mother is formed with the U-shaped sunk structure, covers at son to be formed with the U type bulge-structure that matches with described U-shaped sunk structure.So not only processing trouble of the primary and secondary of the closure assemblies that is provided with lid, and consume material, use inconvenience.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of closure assemblies of container, and this closure assemblies processing is simple, consume material is few, easy to use.

For solving above technical matters, the utility model is taked following technical scheme:

A kind of closure assemblies of container, described container has receiving port, closure assemblies comprises the mother lid that is contained in securely on the receiving port, is encapsulated in the son lid that mother covers, female lid has the oral area corresponding to receiving port, described son lid is the insertion section of U-shaped by the vertical section and is made of to the flange that peripheral direction extends to form the edge, upper end of insertion section, the outer peripheral face of insertion section closely cooperates mutually with the inwall of oral area, flange withhold mother lid to the small part upper surface.

Described female lid is annular arrangement, and the insertion section is a drum shape, and flange also is an annular arrangement.

Described female lid is recessed to form concave face downwards near the upper surface of described oral area, and flange is withheld to the small part concave face.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:

The son lid is the insertion section of U-shaped by the vertical section and constitutes towards the flange that peripheral direction extends to form from the edge, upper end of insertion section, directly insert in the opening of female lid the insertion section, and closely cooperate mutually with the inwall of opening, thereby finish encapsulation to container, this package assembling is easy to use; Owing to need not to offer groove and projection, processing is simple, consume material is few, thereby productive costs is low.

Description of drawings

Fig. 1 is a fractionation scheme drawing of the present utility model;

Wherein:

1, female lid; 2, Zi Gai; 10, oral area; 11, concave face; 20, insertion section; 21, flange.

The specific embodiment

The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment:

As shown in Figure 1, be used for package metals packing jar according to the closure assemblies of present embodiment, have circular receiving port in the upper end of mental package jar, the purpose of closure assemblies is sealed this receiving port exactly, thereby finishes the sealing to packing jar.

Above-mentioned package assembling comprises female lid 1, son lid 2, and in use, female lid 1 is to link to each other with the receiving port of mental package jar.Female lid 1 oral area 10 that has corresponding to receiving port, son lid 2 correspondences are installed on the oral area 10.20 limit, the upper end on even keel flange 21 that forms that stretches out constitutes son lid 2 by barrel-shaped Plug Division 20 and from the Plug Division, and during encapsulation, son covers 2 Plug Division 20 corresponding inserted in oral area 10, and the outer peripheral face of Plug Division 20 closely cooperates mutually with the inwall of oral area 10; Simultaneously, 21 of flanges are withheld on mother is covered 1 upper surface.

For convenience son lid 2 being covered 1 from mother separates, the upper surface near opening 10 of female lid 1 is recessed to form concave face 11 downwards, flange 21 is withheld on the part surface of concave face 11, between flange 21 and female lid 1, there is the slit like this, by the slit, power is mentioned son lid 2 and final and female lid 1 is separated thereby can apply flange 21 easily.

In sum,,, avoid offering groove and raised structures, on the one hand, can reduce the consumption of material and the production and processing of simplification lid by change to mother's lid and son lid shape according to closure assemblies of the present utility model; On the other hand, make closure assemblies more convenient in use.
