Abstract

The invention discloses the structure of a seal opening for a plastic container. The structure comprises a bottle body, a bottle neck and a bottle stopper, wherein the bottle body is an independently-machined part; the bottle neck and the bottle stopper are a connected cup joint part independently machined by the plastic, the top surface of the bottle neck and a contact part of the bottle stopper are mutually integrated, the top surface of the bottle neck is provided with a circle of easy-pull groove, and the easy-pull groove is torn, so that the bottle neck and the bottle stopper can be separated from each other; and the bottle neck of the connected cup joint part is fused with an opening of the bottle body through electromagnetic induction heating by an aluminum foil ring or an aluminum foil wafer. The structure disclosed by the invention is simple to manufacture, and good in seal effect, and can be repeatedly and continuously sealed by the stopper after being opened for once.

Description

The seal structure of plastic container

Technical field

The present invention relates to splendid attire food made of plastic, medicine airtight container, relate in particular to the seal of this container.

Background technology

The bottled container that existing plastics are made all is that design has bottleneck more than body, and design has a bottle neck on the bottleneck, when splendid attire food, medicine, all is to add revolving bottle cap seal mouth, also will adopt the hot pressing aluminium foil to seal before capping.Weak point is, the one, and the bad processing of bottle neck part during process vessel, the 2nd, process bottle cap separately, the 3rd, control step is many during sealing.For example beverage can is to adopt the encapsulation of aluminum alloy easy-open lid, and weak point is disposable use, can't reuse.Some bottled container is to adopt stopper that the bottle neck is sealed for another example, or use crown cap press seal, weak point be to open to bother, and need use professional tool.

Summary of the invention

For the technological deficiency that overcomes existing airtight container seal structure processed complex, sealing effectiveness difference and can not reuse, the present invention designs a kind of new seal structure.

For achieving the above object, the technical scheme that the present invention takes is:

A kind of seal structure of plastic container, it comprises body, bottle neck and bottle stopper, it is characterized in that, described body is the parts of processing separately; Described bottle neck and bottle stopper are Contiuum type socket parts of processing separately with plastics, and the end face of bottle neck and bottle stopper contact site be one each other, are provided with the easy kerve of a circle at bottle neck end face, by tearing easy kerve bottle neck are separated easily with bottle stopper; The bottle neck of Contiuum type socket parts fuses together by electromagnetic induction heating and body oral area with aluminium foil ring or aluminium foil disk.

The structure preferred version of above-mentioned Contiuum type socket parts is as follows:

The one,, bottle stopper bottom is in bottle neck fully or stretches in the body, and the end face of the end face of bottle neck and bottle stopper one each other, is provided with the portion of pinching of carrying at the bottle stopper end face.

The 2nd,, the bottom of bottle stopper is in bottle neck or stretches in the body, high bottle outlet neck top, the top of bottle stopper, bottle neck end face and bottle stopper contacts side surfaces position be one each other.

For saving in material, bottle stopper is a cavity body.

The socket fit structure of above-mentioned bottle stopper and bottle neck is that cone match or cylinder cooperate.

When needs are opened container, tear easy kerve, the portable portion of pinching of carrying, the rotation bottle stopper one firmly makes bottle neck separate with bottle stopper slightly, extracts bottle stopper out, can open container, and this moment, the bottle neck was stayed on the body.

Good effect of the present invention is:

Saved the labyrinth of bottle neck part and bottleneck when 1, making body, made simple.

2, because bottle neck and plug are the plastics disjunctor parts of processing separately, handling ease.

3, owing to adopt electromagnetic-induction heating method encapsulation oral area, encapsulation is timely, good sealing effect; Can continue to seal with stopper repeatedly after once opening.

4, since easily kerve be located at a bottle neck end face, when tearing easy kerve revolving bottle plug, the dust on the bottle stopper can not fall into container from the gap between bottle neck and the bottle stopper, when reusing, the bottle stopper end face of outwarding winding covers on the bottle neck just as a lid, makes sealing effectiveness better.

The specific embodiment

Embodiment one:

As Fig. 1 and shown in Figure 6, a kind of seal structure of plastic container, it comprises body 1, bottle neck 4 and bottle stopper 3, described body 1 is the parts of processing separately, the end face of body 1 is designed to the outlet less than the body external diameter, and described bottle neck 4 and bottle bottle stopper 3 are the plastics disjunctor socket parts of processing separately; The bottle neck of plastics disjunctor socket parts exports at body 1 by the electromagnetic induction heating fusion with aluminium foil ring 2; The structure of above-mentioned bottle neck 4 and bottle stopper 3 disjunctor socket parts is: bottle neck 4 and bottle stopper 3 cylinders closely cooperate, and bottle stopper 3 is in bottle neck 4 fully, and the end face of bottle neck 4 and the end face of bottle stopper 3 be one each other, are provided with the easy kerve 6 of a circle at the end face of bottle neck 4; Be provided with the portion of pinching 5 of carrying on bottle stopper 3, bottle stopper 3 is cavity body.

Embodiment two:

As Fig. 2, shown in Figure 6, embodiment two structures and embodiment one are basic identical, and different is: the bottle neck 4 and bottle stopper 3 conical surfaces closely cooperate.

Embodiment three:

As Fig. 3 and shown in Figure 6, embodiment three structures and embodiment one are basic identical, and different is: the end face of body 1 is designed to uncovered, and bottle neck 4 usefulness the aluminium foil disks 7 of plastics disjunctor socket parts fuse on body 1 is uncovered by electromagnetic induction heating.

Embodiment four:

As Fig. 4 and shown in Figure 6, the structure of embodiment four and embodiment two are basic identical, and different is: the bottle neck of plastics disjunctor socket parts exports at body 1 by the electromagnetic induction heating fusion with aluminium foil disk 7.

Embodiment five:

As shown in Figure 5 and Figure 6, the structure of embodiment five and embodiment four are basic identical, and different is: the bottom of bottle stopper 3 is in bottle neck 4, high bottle outlet neck 4 tops, the top of bottle stopper 3, and the position that bottle neck 4 tops contact with bottle stopper 3 is one each other.

Among above-mentioned five embodiment, bottle stopper 3 bottoms can also extend in the body 1.
