Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:

Fig. 1 is structural profile schematic diagram of the present invention;

Fig. 2 is the structural profile schematic diagram of Composition spacer.

Detailed description of the invention

As depicted in figs. 1 and 2, the combined bottle cap of information code sealant of the present invention, comprises bottleLid 100 and Composition spacer 200.

Wherein, bottle cap 100 is plastic bottle closure, comprises shirt rim 101 and roof 102 and card biting the end of knot structure 103.

Composition spacer 200 is positioned at bottle cap 100 and is attached on roof 102. This Composition spacer 200By pad 210, diaphragm seal 220 and the binding material between pad 210 and diaphragm seal 220Layer 230 composition. For by product-filled be food, the material of bonding material layer 230 is for meeting foodParaffin or the pectin of safety, it can be bonded together pad 210 and diaphragm seal 220, andAbsorbed by pad 210 in the situation of being heated, thereby pad 210 is separated with diaphragm seal 230.

In the inside of bottle cap 100, the position that shirt rim 101 approaches root has can block composite padThe card biting the end of knot structure 103 at sheet 200 edges. This card biting the end of knot structure can be the interrupted outstanding latch distributing a week,Also outstanding snap ring that can continuous one week.

Diaphragm seal 220 by PUR adhesion coating 221, sealant 222 and transparent covering layer 223 underTo upper compound formation successively.

PUR adhesion coating 221 adopts plastic sheeting, and this material can be utilized contactless ultrasonic waveOn solder technology welding bottleneck. Certainly other material can also can be adopted, as PUR.

Sealant 222 adopts metal-containing material, and for example aluminium foil or aluminizer can printing traders on itProduct trade mark, also can be implemented printing by the information code such as Quick Response Code, bar code printing equipment.

Transparent covering layer 223 is plastic sheeting, and such as 0PP, PET, NY etc., to improve outward appearance and to carryHigh strength.

In the present embodiment, diaphragm seal 220 is being printed with information code with respect to the front of pad 210,Be printed with the information code such as Quick Response Code or bar code at the upper surface of diaphragm seal 220. Information code canBe printed on sealant 222, then covered by transparent covering layer 223, also can directly be printed onThe surface of bright cover layer 223.

Pad is paperboard or the foamed sheet that adopts food security. This material pad has goodElasticity can be blocked by card biting the end of knot structure 103, and possesses good absorbability, can be under heating stateAbsorbent binder material layer.

Be exactly more than the combined bottle cap of information code sealant of the present invention, this combined bottle cap can lead toCross easy mode and carry out bottle sealing, concrete step is:

A, the combined bottle cap of above-mentioned information code sealant is filling or pack complete bonnet at commodityTight bottleneck, makes the PUR adhesion coating 221 of diaphragm seal reverse side fully contact with bottleneck.

B, bottle cap and bottleneck are heated, use contactless high-frequency welding manner to heat,Sealant 222, owing to containing metal material, produces heat in high frequency environment, makes PUR adhesion coating221 are heated welds with bottleneck, and then completes the sealing to bottleneck; Meanwhile, due to high-frequency weldingProcess produces heat, and this heat can make to form paraffin or the pectin fusing quilt of bonding material layer 230Pad 210 absorbs, thereby pad 210 is separated with diaphragm seal 220.

Because diaphragm seal 220 and bottleneck bond, pad 210 is fixed by card biting the end of knot structure 103,And diaphragm seal and pad have separated in the time of sealing, thus consumer open after bottle cap, pad withDiaphragm seal also can be retained in bottle cap after separating. And after separating, consumer also can see diaphragm sealPositive information code. Due to information code before consumer opens bottle cap all the time outside be not exposed toIn hermetically-sealed construction, there is very strong disguise, stopped information code and be replicated and steal the risk of brush. AgainBecause information code is the outside that is positioned at diaphragm seal, do not exist yet with bottle in product come in contact and polluteThe problem of product.

After can ensureing that pad separates with diaphragm seal, pad can also be retained in bottle cap, does not adoptCard biting the end of knot structure, can also adopt other modes to realize, for example, directly pad is bonded in to the inner top of bottle capOn wall, or also increase one deck PUR adhesion coating at the upper surface of pad, in when sealing, by padThe heating of sheet and bottle cap is finally bonded on roof pad.

Can find out by foregoing detailed description, it is directly not sudden and violent that combined bottle cap of the present invention has information codeExpose outside, disguised by force and can with, side simple by the product-filled advantage contacting and encapsulating methodJust, be conducive to improve packaging efficiency.
