Description

Cigarette with fire-retarded butt

The utility model belongs to the cigarette of gas defence of preventing fires

The length that the cigarette of this fire-retardant stub can be scheduled to stub, purpose is as follows:

1. add Frpipe in the cigarette, stop firing of predetermined stub, the flue gas poisonous substance of stub enrichment just can not discharge, and the effect of gas defence fireproof is arranged;

2. when cooperating the utility model to use smoking set, the domestic new suitable long stub of filter poison cigarette is convenient to clear up smoking set, and the Frpipe of available cheapness replacement filter tip, eliminate filter tip because of discharging poison gas near burning-point.

Document that can be for reference at present, " the coating type self-extinguishing of cigarette is to be the surface, inside that fire proofing is coated on cigarette paper with fire-resistant argillic horizon to US4480650, plays anti-fire action.

The utility model is more more except that malicious function than general self-extinguishing of cigarette, because the stub length that should stay when in making the system design, being scheduled to smoking, a Frpipe is arranged below this section stub, flatten reinforcement filter toxic effect fruit in the cigarette face processing that connects fire-retardant pipe end, or add the agent that removes carbon monoxide in right amount at the Frpipe epimere; If the utility model is supporting with the malicious cigarette of filter, predetermined stub is saved in the upper end of Frpipe.

Assembly method of the present utility model is described in conjunction with Fig. 1:

The cigarette installation diagram of Fig. 1---fire-retardant stub: the following termination Frpipe (2) of stub (1), the fire-retardant termination cigarette of Frpipe (2) props up the upper end of (3), seals paper (4) sealed interface with blank sheet of paper or fire retardant papers.

The utility model during as supporting use designing for manufacturing saved predetermined stub, the stub (1) that promptly is Fig. 1 saves, assembly method is that the fire-retardant termination cigarette of Frpipe (2) props up the upper end of (3), seals paper (4) sealing Frpipe (2) and cigarette and props up the upper end interface surface of (3).

Following 4 kinds of the preparation method of the described Frpipe of Fig. 1 (2):

1. the preparation of double-tube series formula Frpipe: the fire-retardant end of Frpipe is a metal tube (or sheet metal roll cast), and pipe range 3-10mm(4-6mm is long more suitable), internal diameter 2-8mm, external diameter is consistent with the external diameter of the cigarette that is equipped with; The other end of Frpipe is a cardboard tube (it is better to be rolled into multilayer with thin paper), length 10～30mm, the hollow internal diameter 1～9mm of pipe, the external diameter at the two ends of pipe and metal tube consistent, be hollow in the pipe, also can put extremely thin bright absorbent cotton or other filtrates or the placement agent that removes carbon monoxide;

2. the preparation of glass fiber filter paper Frpipe: can directly roll into cardboard tube with flame-retardance fiberglass filter paper and adhesive, or roll with double glazing fiber filter paper therebetween one deck blank sheet of paper, an end of the paper that do not show money or valuables one carries unintentionally is fire-retardant end;

3. the preparation of the Frpipe of aluminum foil paper wall: an end 10mm of cardboard tube inner and outer wall long or pipe entirely is pasted the covering aluminum foil paper form the fire-retardant end of metal covering, this Frpipe and cigarette can seal paper (4) with aluminum foil paper when propping up assembling;

4. other preparation methods: paste the inside and outside wall that covers cardboard tube with fire proofing, or become Frpipe with anti-flaming dope dipping or coating cardboard tube, or with a metal tube as Frpipe.

The preordering method of the described stub of Fig. 1 (1): can not cut segment length 20～30mm to be predefined for stub (1) promptly be that cigarette props up (3) for remaining one section to there being filter-tip cigarette; To filter-tipped cigarette, below filter tip, stay the long pipe tobacco section of 15～20mm to be predetermined stub (1).
