Abstract

A combustible garbage bag features that it is made up of non-chlorine synthetic resin and has a special opening and closing method for bag mouth. It can prevent environmental pollution.

Description

The refuse bag that is used to burn

Product of the present invention is a kind of combustible garbage bag that burns usefulness.It can be widely used in collects the rubbish that hospital, public place, office, workshop, dining room and average family etc. are poured out.

The rubbish that hospital, public place, office, workshop, dining room and average family etc. are poured out is of a great variety, comprises living rubbish (rubbish such as dish leaf that throw away in the kitchen), foul, various plastic product, waste paper or the like.At present, carry out burning disposal after these rubbish almost all are to use a kind of so-called refuse bag to collect.It is a kind of be that the cylindric long glued membrane of raw material blow molding cuts off at certain intervals and heat fuses and seals with synthetic resin such as polyethylene, polyvinylchlorides, its opposite side is provided with the refuse bag of opening.The plastic product that is burned contains the material of noxious gases such as might producing polyvinylchloride, polyvinylidene chloride, polyacrylinitrile.In addition, give birth to rubbish and printing paper, when burning, can produce noxious gas, particularly burn the rubbish time-like of chloride element,, have the possibility of hypertoxic gases such as generation bioxin under certain condition if with after polyester article etc. mixes.

On the other hand, the rubbish that hospital pours out, if tightly peristome is not fastened, the waste flow of the inside comes out to produce the problem on the health such as stench, also can bring the problem of very big difficulty in recycling.

In the past, the industry refuse was distinguished by particular industries refuse kind, in the workshop or the burning disposal of special disposal field.On the cleanup system of installation for blast furnace gas, try every means, grasp the input of the slack lime treatment additive of using and the clean combination of washing drying dirt collector as quilt.

But present situation is to burn the livings rubbish that is collected in little refuse bag etc. generally during rubbish burning, for causing that the problem that environment pollutes also do not take any effective method.

Purpose of the present invention has following 3 points:

The burning refuse bag that the one, provides a kind of hand of not making dirty just can fasten.

The 2nd, provides a kind of personnel of recovery to reclaim when being positioned over the refuse bag of Refuse bin, and is not contaminated, and can wholesomely reclaim the burning refuse bag of rubbish.

The 3rd. provide a kind of rubbish of packing into directly to burn, and can suppress the refuse bag that noxious gas produces, reduces environmental pollution.

In order to achieve the above object, the present invention is to be raw material with body with chlorine-free synthetic resin, and the switching of the peristome burning refuse bag that adopts specific process to constitute.

The present invention refers to make as raw material with the synthetic resin of chlorine-free the body of refuse bag.

Refuse bag to film-form or bag-shaped formation, as long as in the raw material chlorine-free synthetic resin of this refuse bag, in the molecule not chloride ion-containing, so to its as the kind of the chlorine-free synthetic resin of raw material without limits, the chlorine-free synthetic resin that exemplifies can be polyethylene, polypropylene, PETG etc. Wherein optimal is polyethylene. And polyvinyl chloride, polyvinylidene chloride etc. are when burning, owing to contain the chlorine element and have the organic matter that contains chlorine may have poison gas to discharge, so do not use now.

With regard to non-chlorine synthetic resin, can use the various additives of film-form moulding without large impact. Additive is such as lime, dyestuff, antistatic agent, lubricant etc. This makes it without the effect that poisons during wherein lime (calcium carbonate) can play in when burning and poison gas. Dyestuff can be with black, also can account for 10～50% of all constituent weight with the use amount of other colors of liking, lime (calcium carbonate), and preferably 20～40%.

Refuse bag of the present invention is to use above-mentioned chlorine-free synthetic resin at material, and has that the film of non-water penetration consists of, and 1 film bending, fuses also at the one end and can produce this refuse bag. According to the characteristics of blow molding, can produce as required the cylindrical shape of endless, also can fuse, cut off to random length. The film thickness of formation bag is 10～50% μ m, or preferably at 20～35 μ m.

Design at the method for opening and closing of refuse bag body openings section is very necessary. That the peristome of bag inwardly is converted into the path of belt as this method for opening and closing, by the structure of in path, fastening the gathering that belt seals or the pleat that the peristome of passway structure has the convex-concave shape, and be to give as security or with the ring of mutual chimeric formation, inlay slide fastener or button with inlaid in the ring or improve the method for sealing with bonding agent with hand. Simultaneously, can carry out various printings and color identifying and can change the belt color according to the design of the method for opening and closing of belt at the body of refuse bag, so also provide possibility for understanding rubbish kind.

For the present invention, contain under the situation of calcium carbonate in constituting the synthetic resin of refuse bag, its chemical action is clear and definite, at first is to be considered to when burning the effect that the various acidic gas that produce from rubbish are played neutralization, fix.Particularly be considered to, when containing rubbish (giving birth to rubbish, the plastics etc.) burning of chlorine elements such as chlorine element, the acidic gas that produces produces noxious gases such as bioxin when reacting with other organic gas, calcium carbonate can neutralize with this acidic gas that contains the chlorine element.

Embodiment

Bottom is with reference to the explanation of accompanying drawing to concrete instance.

Example 1

Calcium carbonate that accounts for total weight 30% and the mixing back of polyethylene are passed through the annular die blow molding, it is drawn out circumference is 100cm, the continuous cylindric thing of thickness 25 μ m its entirely folding back (smooth purpose be for 2 can be overlapping), rolls up with the deal of 500m.Next, this cylindric thing is pulled out from reel, and the printer by bending passes through cutting off machine again after certain intervals prints continuously, makes 2 coincidences fuse and be cut into simultaneously long 175cm at certain intervals, wide 50cm has only the bag of an end opening.Secondly, the long 10cm in the two ends of the opening portion of this bag, wide 1cm partly cuts away, and inwardly turns down with 8cm from peristome, and its edge is fused, and just forms the path that 2 belts can pass through at opening part like this.

Secondly, blue belt with the red belt of the wide 2cm of the same material of this bag and wide 2cm is passed the path of 2 belts of top, again the thawing of the top ends of each belt is coupled together, like this refuse bag that has 2 ring-type belts therefrom to pass with regard to the opening part that is formed on bag.

Fig. 1 is the oblique drawing of this refuse bag.Refuse bag 1 is to be made of the body 2 of bag and rope 3.The lower end of body 1 of bag is to fuse part 4, and it is fused sealing by 2, and is opening in the body upper end, and this shape has constituted 5, cut off at the two ends of opening part 5 just to form 6 and 6 '.In the upper end of bag body bag turnover to the inside, turnover end place and a bag body are fused together just
