Abstract

The utility model relates to a protection ring structure of barrel containers, in particular to an external protection ring for a barrel, which comprises a plastic protection ring body in a hollow annular shape. An axial clamping groove in clamped connection with the edge of the barrel is arranged on the annular protection ring body; a fastening flange is arranged on the inner side of an outer ring of the axial fastening groove in a projecting manner; an anti-counterfeiting ring is axially connected to an outer ring of the axial fastening groove; and the inner ring of the axial fastening groove extends towards the center to form a check ring capable of carrying a barrel cover. The protection ring structure has the advantages of 1 fine anti-counter function, 2 capability of facilitating opening of the barrel cover in later use, 3 integral hollow design, saved material and cost, 4 independently manufacture and formed protection ring suitable for containers made of any materials, 5 capability of forming fine sealing effect as the clamping groove is tightly fastened with the barrel edge, 6 capabilities of preventing direct metal collision among barrels, avoiding damage to a barrel body and the like.

Description

A kind of barrel of external application back up ring

Technical field:

The utility model relates to the back up ring structure of barrel class container, refers in particular to a kind of barrel of external application back up ring.

Background technology:

The container of products such as existing charge of oil lacquer generally still is to use comparatively traditional irony paint kettle.The bung edge of this type of paint kettle has lug boss upward, and to the center interior ring is arranged, and is equipped with the recessed bung in middle part then, forms sealed package with this.No matter this mode opens all very effort and inconvenience of still later stage unlatching for the first time.In addition, traditional modes such as sealing bar is mainly adopted in the false proof design of this type of container at present, and this antiforge function is relatively poor, is easily changeed the gap utilization by the lawless person, brings loss to the customer.Certainly, also there are some to have better false proof design-calculated container or lid at present, for example Chinese utility model patent 200620065809.3 disclosed " a kind of bottle cap " etc., the false proof design of this class must be one-body molded with bottle cap, only be applicable to plastic bottle, so Applicable scope is narrow.

The utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of prior art, and a kind of barrel of external application back up ring is provided.

The utility model realizes that the technical scheme that its purpose adopts is: a kind of barrel of external application back up ring, has a plastic cement back up ring body, described back up ring body is the open circles annular, described annular arrangement back up ring body be provided with can with the axial draw-in groove of barrel rim clamping, the inboard, outer ring of described axial draw-in groove convexes with edge clipping, and the outer ring axially is connected with false proof ring; The inner ring of described axial draw-in groove extends to form the back-up ring that can accept bung to the center.

Described axial draw-in groove is " inverted U-shaped ".

One end of described false proof ring is provided with first draw ring.

Outer ring in described annular arrangement back up ring body is provided with second draw ring.

Advantage of the present utility model is: 1. can play good anti-fake effect; 2. make things convenient for bung to open in the time of can using in the later stage; 3. whole hollow design, energy saving in material and the cost of adopting; 4. the back up ring makes moulding separately, and the container of applicable any material uses; 5. draw-in groove and barrel rim screens are tight, can form good sealing effectiveness; 6. can play the metal direct impact that prevents between bucket and the bucket, avoid damaging staving etc.

Description of drawings:

Fig. 1 is a block diagram of the present utility model;

Fig. 2 is a cutaway view of the present utility model;

Fig. 3 is a main TV structure scheme drawing of the present utility model;

Fig. 4, Fig. 5 are the part sectional views of running condition of the present utility model.

The specific embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

Shown in Fig. 1～3, bucket external application described in the utility model back up ring has a plastic cement back up ring body, described back up ring body integral body is the open circles annular, described annular arrangement back up ring body is provided with axial draw-in groove 1, described axial draw-in groove 1 is " inverted U-shaped ", this axial draw-in groove 1 can with the clamping mutually of bung edge; 11 inboards, outer ring of described axial draw-in groove 1 convex with edge clipping 111, and this edge clipping 111 makes axial draw-in groove 1 more tight with the clamping of bung edge; 11 axially are connected with false proof ring 12 in the outer ring, and an end of this false proof ring 12 also is provided with first draw ring 121, are convenient to false proof ring 12 is torn use.The inner ring 13 of described axial draw-in groove 1 extends to form back-up ring 130 to the center, and this back-up ring 130 is used to accept bung, and promptly described back-up ring 130 internal diameters are less than the external diameter of bung, and the external diameter of the internal diameter of back-up ring 130 and bung inner concave quite is good (as shown in Figure 5).Outer ring 11 in described annular arrangement back up ring body is provided with second draw ring 112, is convenient to whole protecting circle body is taken off.

After the utility model adopts said structure, as shown in Figure 4, after staving 2 and bung 3 are packaged, the utility model back up ring is installed in bung 3 tops by modes such as hot pressing, the false proof ring 12 and the outside of staving 2 are fitted tightly, and thereby the axial draw-in groove 1 that makes the back up ring body engages with the bung edge of staving 2 and makes back up ring and staving 2, bung 3 is linked as an integral body, and since back-up ring 130 internal diameters that back up ring inner ring 13 extends less than bung 3 external diameters, the back-up ring 130 of back up ring blocks the joint of bung 3 and staving 1, therefore under the situation of not taking off the back up ring body, bung 3 can't be opened with staving 2; And to take off the back up ring body, and then need to utilize earlier first draw ring 121 that false proof ring 12 is removed, can the back up ring body be taken off by second draw ring 112 then.Like this, if during the product that the customer buys, can judge authenticity of products or be not used according to whether false proof ring 12 is complete, thereby realize antiforge function.

Again as shown in Figure 5, behind first unlatching bung 3, can earlier the utility model back up ring be connected to the bung edge of staving 2 by axial draw-in groove 11, and then cover bung 3, because of the back-up ring 130 of back up ring can be accepted bung 3, and the inner concave outer wall of back-up ring 130 madial walls and bung 3 can form good sealing, thereby is convenient to store; What is more important when opening, because bung 3 is undertaken on the body of plastic cement back up ring next time, and the outside of back up ring body is provided with second draw ring 112, therefore can pass through second draw ring 112 pull-up back up ring easily, promptly open bung simultaneously, laborsaving quick; And need not bung 3 and back up ring body are separated, directly will get final product on back up ring and bung 3 integral cap after using.

In sum, the utility model is simple in structure, and is easy to use, and applied widely, and result of use is good.
