Abstract

The utility model discloses a new barrelhead structure of packing barrels, which is mainly formed by assembling a bunt edge at the periphery edge of a barrelhead, and a groove is arranged at the inner side of the bunt edge. The periphery edge of the upper end of a packing barrel is provided with a flange which is suitable to be tightly clamped into a ring groove of the barrelhead; the periphery at the upper end of the bunt edge is sheathed with an elastic ring which not only can cause the effect of complete seal to be obtained after the barrelhead and the packing barrel are clamped but also has the characteristic that the elastic ring is unable to be recovered after damaged, and the function of recognition can be obtained, and thus, the defects can be improved that the packing barrel and the barrelhead are bonded only by seals in a conventional mode, the effect of the complete seal is not good, and the complete seal is easy to recover after damaged and can not be recognised effectively.

Description

Cover structure of packing drum

The relevant a kind of new packing barrel bung structure of the utility model refers to that especially a kind of sealing effectiveness is good, and has the recognition function that can't restore after the destruction.

Packing barrel generally is widely used in all trades and professions, for example the splendid attire raw material of industry, oil product, fertilizer, medicine, food ... Deng, especially more be applicable to the transaction of huge quantity, so its leak tightness and intact Feng Xingshi are extremely important.Commonly use the sealing of packing barrel bung, mostly utilize to screw togather or mode such as engaging, at most again between packing barrel and bung with adhesive tape seal in addition, reach the effect of sealing to reach sealing.The sealing of right screw-in version since must the rotation bung a few, obviously comparatively time-consuming, nor be applicable to the bung that area is bigger.Moreover, intact envelope mode with adhesive tape strip of paper used for sealing seal, also very easily restored by people's unpacking earlier and then seal, so just, can't identification its whether once broken seal, therefore be often take place to be substitute or the capacity shortage or even dispute such as the return of goods, this is real totally unfavorable to the seller (especially production plant), not only causes damage, even the loss of goodwill more takes place sometimes.Therefore, packing barrel bung sealing good and identification easily and intact envelope structure have its cooresponding essentiality in fact, because it not only can take the production and selling into account person's's (being the seller) interests, and more can protect customer's rights and interests.

Main purpose of the present utility model promptly not only has excellent sealing effect providing a kind of, and has more the whether new packing barrel bung structure of intact envelope of easy identification, in order to do can avoid substitute, bad phenomenon such as shortage.

The utility model is for reaching above-mentioned purpose and effect, and in the bulk technology solution of being taked, this new packing barrel bung structure comprises: a body, but it is the hollow container of an article-containing, outside projection one flange of its top periphery; One bung, edge is supported in the outside projection one of its periphery, should support the edge lower end and have a groove, can engage sealing with the flange of body, and the upper end then has a bearing; It is characterized in that this bung supports the edge upper end, be positioned at multiple consubstantiality ground, the outside of the bearing that should support the edge consubstantiality and have an elastic band, the bottom of this elastic band and support between the edge and have a gap and make and have weak coupling link between the two, the power of inwardly bringing together that this elastic band has, make flange tightr with engaging of groove, so that can't open bung and the intact envelope of tool effect, go to pot and removed when sealing effect the recognition effect of tool identification immediately in this elastic band.

Now lift that details are as follows with next preferable possible embodiments conjunction with figs.:

Figure 1 shows that the three-dimensional exploded view of embodiment of the present utility model

Figure 2 shows that the assembled sectional view when embodiment of the present utility model finishes envelope

Figure 3 shows that the assembled sectional view when embodiment of the present utility model seals

As shown in the figure, packing barrel of the present utility model comprises: body 10 and bung 20; Wherein, this body 10 is for being hollow circle tube, and the outside projection of its top periphery has a flange 11.

Bung 20 utilizes the PE plastic cement material one-body molded, and the outside projection of its periphery has one to support edge 21.Should support inboard, edge 21 lower end and have a groove 22, this groove 22 can snap in and driving fit for the flange 11 of body.Should support consubstantiality ground, edge 21 upper end and have a bearing 23, the outside of this bearing 23 has an elastic band 24 again, the bottom of this elastic band 24 with weak coupling link be connected moulding to edge 21, and therefore have a gap 25 between the two.

During according to above-mentioned tectonic association, to being pressed on the body 10 under bung 20 application of forces, the flange 11 that makes the groove 22 of bung 20 align body 10 snaps in and driving fit.Because this bung 20 is to utilize the PE plastic cement material one-body molded, thereby slightly has the elastic telescopic performance, so when its application of force was pressed down, groove 22 natures of its bottom can slightly expand outwardly, and flange 11 can be snapped in smoothly.And because these groove 22 its shapes and flange 11 are suitable, add to edge 21 tops, outside promptly on this groove 22, have more an elastic band 24, it has the elastic force of inwardly bringing together, so after can making flange 11 in a single day snap in groove 22, not only can reach the degree of suitable driving fit, and more can reach the intact envelope effect that bung 20 can't be opened.This moment, bung was the state that connects airtight with body 10 lateral walls to edge 21, as shown in Figure 2.

When desire is removed its intact envelope with bung 20, it is the gap 25 that must utilize instrument (for example corkscrew or blade) to insert own elasticity ring 24 and bearing 23 or support 21 at edge, with elastic band 24 with support the intermarginal weak loop section that is connected moulding and cut apart from destruction, just can be as on the direction this elastic band 24 being cut from destruction being shown in shown in Fig. 2 arrow A-A ' or the B-B ', so this elastic band 24 has promptly lost the power of bringing together to groove 22, make to support edge 21 and separate with body 10 lateral walls and have a spacing 26, as shown in Figure 3.Only, at this moment, though bung 20 has lost the effect of envelope, the sealing effectiveness of right still maintenance and body 10.

When further bung 20 being opened as desire, then relend instruments such as helping corkscrew, this spacing 26 is inserted certainly, gradually bung 20 perks are made it to separate with body 10, shown in arrow C-C ' direction among Fig. 3, can reach the purpose that bung 20 is opened.

So by above explanation as can be known, the utility model has possessed following all advantage and effect in the use at least, and far away and more progressive more practical than known person:

(1) utilizes engaging of groove 22 and flange 11, add the power of bringing together of elastic band 24, make bung 20 can reach quite good intact envelope effect, substitute or bad phenomenon such as capacity shortage, thereby can guarantee the producer and customer both sides' rights and interests so can exempt fully.

(2) in case after elastic band 24 goes to pot,, can obtain identification thus though the intact envelope effect of bung 20 is removed immediately, still do not known so also unlikely generation substitute or capacity is short bad incline resemble; Easy speech, promptly the utlity model has suitable good identification effect.

(3) bung 20 of the present utility model intact envelope render a service remove after, but itself and body 10 engaging of mat groove 22 and flange 11 still and reach quite good sealing effectiveness.

(4) reach bung 20 and seal with intact with the sealing of body 11, all quite easy and rapid in operation.

Claims

1, a kind of new packing barrel bung structure comprises:

One body, but it is the hollow container of an article-containing, outside projection one flange of its top periphery;
