Abstract

The invention belongs to the field of environmental protection products, and in particular relates to a garbage bag and a manufacturing method thereof. It includes the bag body and the bag mouth, and also includes the thickened fixing part, which is arranged under the bag body. The radius of the thickened fixing part is smaller than the radius of the bag mouth. The whole garbage bag is in the shape of an inverted cone, and the thickened fixing part is made of paper It is made of high-quality materials or degradable materials, double-sided laying and bonding of conventional plastics, and formed into a fixed bowl or dish shape, with a thickness of 1-3mm and a height of 1/5-1/3 of the height of the garbage bag . The garbage bag of the present invention will not be easily broken, and can contain liquid garbage and garbage leachate, which is beneficial to protect the indoor environment; and when the garbage bags are stacked, they are in the form of nesting each other, which can save the space occupied by the garbage bags; and is convenient Used in combination with various types of common garbage cans, it has greater practicability and convenience, is beneficial to environmental protection, is economical and practical, and is suitable for widespread promotion.

Description

A kind of refuse bag and preparation method thereof

Technical field

The invention belongs to the environment-friendly products field, be specifically related to a kind of refuse bag and preparation method thereof.

Background technology

The proprietary design of relevant refuse bag is a lot, convenient unitized design, the refuse bag that generally concentrates on refuse bag and sewage disposer seals and design etc. is extracted in portable design, refuse bag, is proprietary designs such as 2008202035575,200810337734,032356218,912160446,2007200139541 as application number.Refuse bag commonly used is a plastic material, volume extraction-type and the disconnected formula tearing mode of point, no matter whether be thickening type, there are the following problems usually to use this common refuse bag: although refuse bag intensity can satisfy the needs of splendid attire rubbish usually, but refuse bag is usually had the prominent rubbish of quil and rib to be punctured or punctures, so that percolate is leaked out, particularly can produce more percolate for containing more liquid household garbage or rubbish from cooking, gently then stain sewage disposer, heavy then overflow on the floor and spill leak in abandoning on the road of sending rubbish, living environment is had very disadvantageous negative effect, and the refuse bag of carrying the continues patter of raindrops to go out when abandoning be very inconvenient and embarrassed.Have not yet to see about solving the proprietary design of foregoing problems.

Summary of the invention

In order to solve present domestic prior art and principle of design defective and deficiency in the field, the object of the invention is to provide a kind of refuse bag and preparation method thereof.

The refuse bag that the present invention proposes, comprise bag 4 and the sack 5 that surrounds by the upper surface of this bag, also comprise thickening connecting element 2, bag 4 belows are embedded in the thickening connecting element 2, and thickening connecting element 2 radiuses are less than the radius of sack 5, refuse bag integral body is is inverted the frustum shape, thickening connecting element 2 is a raw material with paper material or degradation material, two-sidedly lays bonding conventional plastics and makes, and form the fixing bowl or the shape of dish, its thickness is the 1-3 millimeter, highly is the 1/5-1/3 of refuse bag height.

Among the present invention, sack 5 both sides are provided with triangle folding line 3, and sack 5 width of sack both sides triangle folding line 3 after folding are identical with thickening connecting element 2, and an employing disconnected formula structure 1 is connected between the sack 5 between adjacent two refuse bags and the thickening connecting element 2.

Among the present invention, a plurality of refuse bags are treated the time spent, and bag 4 can compress and be folded to thickening connecting element 2, is the form that mutual cover is piled up.

The method for making of the refuse bag that the present invention proposes, concrete steps are as follows:

1. sack 5 and the thickening connecting element 2 choosing bag 4, surround by the upper surface of this bag;

2. with step 1. each parts of choosing of process carry out machine-shaping by mould;

3. with step 2. the refuse bag of process machine-shaping assemble.

Beneficial effect of the present invention is:

The refuse bag bottom is made for fixedly bowl-type or the dish that thickening is strengthened with papery or degradation material, thickening connecting element tough and tensile intensity is enough to resist and has engaging in internal strife of the prominent or quil rubbish of rib, and can not break easily, so refuse bag can hold liquid rubbish and percolate, can not form overflowing and spilling leakage of percolate, be convenient to abandoning of rubbish and send, help protecting indoor environment; And stand-by refuse bag is the form that mutual cover is piled up when stacking, and can save refuse bag and take up room; And be convenient to be used in combination with various common car wastebasket, have bigger practicality and convenience, help protecting environment, economical and practical, suitable extensively popularization.

Description of drawings

Fig. 1 interconnects figure for a plurality of refuse bags;

Fig. 2 is the structural representation of single refuse bag;

Fig. 3 piles up dormant state figure for the mutual wedging ring of refuse bag;

Wherein, number in the figure: 1 is the disconnected formula structure of point, and 2 are the thickening connecting element, and 3 is the triangle folding line, and 4 is bag, and 5 is sack.

The specific embodiment

The following examples are to further specify of the present invention, rather than limit the scope of the invention.

Referring to Fig. 1-Fig. 3, the present invention has developed a kind of thickening dish bottom environmental protection disjunctor refuse bag, takes following steps:

This environmental protection disjunctor refuse bag is made up of thickening connecting element 2 and bag 4, thickening connecting element 2 is arranged on bag 4 belows, thickening connecting element 2 radiuses are less than sack 5 radiuses, integral body is is inverted the frustum shape, sack 5 triangularity folding lines 3, sack 5 width behind the folding line are identical with thickening connecting element 2, are connected to put the formula structure 1 of breaking between the sack 5 of adjacent two refuse bags and the thickening connecting element 2.

Described thickening connecting element 2 is a raw material for paper material or degradation material, two-sidedly lays bonding conventional plastics and makes, and form fixing dish-shaped shape, and its thickness is the 1-3 millimeter, and dish limit height is 1/5～1/3 of a refuse bag height.

Environmental protection disjunctor refuse bag bottom described thickening is dish-shaped, a plurality of refuse bags are treated the time spent, and the dish bottom is fixed into shape, and non-reinforcement can compress and be folded in the dish-shaped bottom, for overlapping the dish-shaped attitude of piling up mutually.

In addition, the present invention and not meaning that by scheme drawing and specification sheets limits to, and can change to some extent under the prerequisite that does not break away from design aim and principle thereof.
