Abstract

Easy-opening packaging barrel cap with open slot, including bung ontology made of plastic material, interior concave station is formed on the inside of bung ontology, flanging is formed on the outside of bung ontology, it is formed with bail wire in bung ontology, forms seal groove between bail wire and flanging, is formed with barb ring in flanging inner wall, the lower end of flanging connects anti-theft ring, and the flanging lower end is formed with 3 or 3 or more open slots.As long as slightly firmly opening bung ontology when uncapping, the lower end that flanging separates will under the action of plastic material elasticity outside flexible deformation, make flanging and staving disengagement suitable for reading, when being closed bung ontology, same flanging lower end outside flexible deformation under the action of plastic material elasticity, and when phenomena such as staving being toppled over, thrust after substance is toppled in bucket is then not enough to the flanging of bung ontology being pushed outwardly flexible deformation, therefore guarantee bung ontology under the premise of clamping is reliable, the folding of bung ontology is light, laborsaving.

Description

Easy-opening packaging barrel cap with open slot

Technical field

The utility model relates to packaging barrel caps, more particularly to the easy-opening packaging barrel cap for having open slot.

Background technique

The cover structure of existing pail pack generally comprises bung ontology, and bung ontology is formed with in-flanges, flanging and sealing Ring forms seal groove, and is formed with barb ring in flanging inner wall between flanging and sealing ring, in this way in closure, by turning up The barb and sealing ring on side block the inside and outside wall suitable for reading of staving, and bung will not automatically open when toppling over pail pack, but the structure Have the drawback that: blocking that staving is suitable for reading by flanging and sealing ring, if by inside and outside flange and staving it is suitable for reading between gap Setting too closely, then can block too tight, and bung is caused to be not easy to open, if inside and outside flange and staving it is suitable for reading between gap setting Greatly a bit, and it is unreliable to will lead to clamping, and influences sealing performance.

Summary of the invention

The purpose of this utility model is to overcome prior art there are the shortcomings that, provide and a kind of guaranteeing bung ontology card Under the premise of tight reliable, the folding of bung ontology easily, labour-saving have the easy-opening packaging barrel cap of open slot.

The technical solution of easy-opening packaging barrel cap of the utility model with open slot is: including made of plastic material Bung ontology, bung ontology inside are formed with interior concave station, are formed with flanging on the outside of bung ontology, are formed with clamping in bung ontology Ring forms seal groove between bail wire and flanging, be formed with barb ring in flanging inner wall, the lower end connection of flanging is antitheft Ring, the flanging lower end are formed with 3 or 3 or more open slots.

The utility model discloses a kind of easy-opening packaging barrel cap with open slot, mainly in the lower end of flanging 3 or 3 or more open slots are formed with, are separated the end portion of flanging by open slot, tear initiation is anti-when using for the first time Ring is stolen, when people uncap, as long as slightly firmly opening bung ontology, the lower end that flanging separates will be in plastic material Outside flexible deformation under the action of elasticity is conducive to open bung ontology, close to make flanging and staving disengagement suitable for reading When closing bung ontology, the lower end of same flanging outside flexible deformation under the action of plastic material elasticity is conducive to bung Ontology closure, and when phenomena such as staving being toppled over, the thrust after substance is toppled in bucket be then not enough to will bung ontology outside Flange is pushed outwardly flexible deformation, therefore guarantees bung ontology under the premise of clamping is reliable, and the folding of bung ontology is light, saves Power.

The utility model has the easy-opening packaging barrel cap of open slot, and the open slot is rectangle or square Either arc-shaped or triangle.The flanging lower end is formed with 8 open slots.The depth D of the open slot is flanging 1/3-the 2/3 of height H.The open slot of different depth can be opened up according to the size of bung ontology.

Detailed description of the invention

Fig. 2 is the schematic cross-sectional view of easy-opening packaging barrel cap of the utility model with open slot；

Fig. 3 is partial enlargement diagram at the A of Fig. 2.

Specific embodiment

The utility model relates to a kind of easy-opening packaging barrel cap with open slot, as shown in Fig. 1-Fig. 3, including modeling Expect bung ontology 1 made of material, is formed with interior concave station 2 on the inside of bung ontology, flanging 3 is formed on the outside of bung ontology, in bucket It is formed with bail wire 4 in lid ontology, forms seal groove 5 between bail wire and flanging, is formed with barb ring 6 in flanging inner wall, outside The lower end of flange connects anti-theft ring 7, it is characterised in that: 3 lower end of flanging is formed with 3 or 3 or more open slots 8. 3 or 3 or more open slots 8 are mainly formed in the lower end of flanging 3, by open slot by the end portion of flanging 3 every It opens, tear initiation anti-theft ring 7 when using for the first time, when people uncap, as long as slightly firmly opening bung ontology 1, flanging 3 divides The lower end separated will under the action of plastic material elasticity outside flexible deformation, to keep flanging 3 and staving suitable for reading de- It opens, is conducive to open bung ontology, when being closed bung ontology 1, the lower end of same flanging 3 is in plastic material elasticity Outside flexible deformation under effect is conducive to the closure of bung ontology 1, and when phenomena such as staving being toppled over, substance is toppled in bucket Thrust afterwards is then not enough to for the flanging 3 of bung ontology being pushed outwardly flexible deformation, therefore guarantees that bung ontology can in clamping Under the premise of leaning on, the folding of bung ontology is light, laborsaving.The open slot 8 be rectangle or square or it is arc-shaped or Person's triangle.3 lower end of flanging is formed with 8 open slots 8.The depth D of the open slot 8 is the 1/ of flanging height H 3—2/3.The open slot 8 of different depth can be opened up according to the size of bung ontology 1.
