Abstract
The utility model relates to a packaging product, in particular to a new type composite cement bag with valve port made of plastic. The utility model is characterized in that a valve port (3) is arranged at a corner end of a bag mouth. The valve port (3) is folded concavely into the inner cavity of a bag body (1) to form a right-angled trapezoid. The opening of the valve port (3) is connected with the inner cavity of the bag body (1). A strengthening sheet (2) is folded transversely toward a side of the upper end of the bag mouth. The upper end of the bag mouth, the strengthening sheet (2) and the upper end of the valve port (3) are in sewing connection by a commissural thread (4). The folding width of the strengthening sheet is 25 mm, and the length is 280 mm. The material to be thrown off is used sufficiently. The manufacturer can save plenty of raw and processed materials. The quality of the finished product can be guaranteed. The economic efficiency of the manufacturer is further improved.
Description
Technical field
The utility model relates to package packing supplies, particularly the novel valve port compound cement bag of plastic knitting.
Background technology
In the past mould the volume compound cement bag owing to when can cement, need bear certain temperature, pressure and cement weight, when therefore making finished product, must there be compound cement bag the flanging 25mm of sack place of valve port wide,, just can meets the requirement of cement packing industry with special suture sealing.When making, elder generation cuts through cutting mechanism in the Bag Making Machine, when cut-off knife cuts valve port, can cut out the one piece material of sack to the compound cement bag blank, and the about 280mm * 50mm of area has been wasted in vain.When making sack, sack reflexed 25mm, seal with line sewing more again, whole like this sack will dwindle 25mm.The consumption of this compound cement bag, all want several hundred million every year, and so above-mentioned waste is just very surprising.As shown in Figure 2, the shape of compound cement bag sack place after cutting, cutting originally is that this piece of reinforced sheet (2) is cut, cut dotted line position to the figure, roll over valve port again, again the sack place to side folding 25mm, make the sack and the bag end then, the general oblong of bag (1).
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of novel valve port compound cement bag is provided.
The technical solution of the utility model is that one jiao of end of compound cement bag sack is made valve port (3), and this valve port (3) is converted into right-angled trapezium to bag (1) inner chamber concave, and valve port (3) opening is communicated with bag (1) inner chamber.The sack upper end has reinforced sheet (2) to a side cross break, and has sealing line (4) to be connected with sack upper end, reinforced sheet (2), the sewing of valve port (3) upper end.Constitute novel valve port compound cement bag.
Said reinforced sheet (2) is rolled over wide 25mm, long 280mm.
The utility model has the advantages that saving in material, make the annual lot of materials of saving of manufacturer, improve the economic benefit of compound cement bag manufacturer.
Description of drawings
Further describe embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the full pattern figure after the utility model blank cuts.
The specific embodiment
With reference to Fig. 1,1-bag, 2-reinforced sheet, 3-valve port, 4-sealing line, 5-stitch bottom line.Finished product bag (1) is rectangle, the wide 420mm of bag, long 780mm; The long 280mm of reinforced sheet (2), wide 25mm, cross break is in a side, and valve port (3) is in one jiao of sack, is converted into right-angled trapezium to bag (1) inner chamber concave, shown in the dotted line right angle among the figure.Valve port (3) opening is communicated with bag (1) inner chamber, is used for can cement in bag (1).Sealing line (4) connects reinforced sheet (2), valve port (3) upper end and sack sewing.Seam bottom line (5) connects the sewing of the bottom of former opening.Become the finished product of a compound cement bag like this, could be when can cement, bear certain temperature, pressure and cement deadweight, there compound cement bag must be had the sack place of valve port to fold into 25mm to be wide, with special suture sealing, just can meet the standard-required of cement packing industry.Changed the past when cutting bag of cement valve port shape, removed the material of a slice 280 * 50mm, become reinforced sheet and use, simultaneously no longer when making sack the wide sack of reflexed 25mm sewed.This just makes manufacturer save material greatly, has improved the benefit of manufacturer again, and end product quality is guaranteed, and through trial production with fall the bag test, requirement fully is up to state standards.
With reference to Fig. 2,1-bag, 2-reinforced sheet, 3-valve port.This is before the finished bag, cuts the full pattern of compound cement bag blank from Bag Making Machine, and the dotted line on its figure is represented reinforced sheet (2) cross break place.Reinforced sheet (2) right side and valve port (3) are unconnected, and valve port (3) is to the recessed folding of bag (1) inner chamber.
Claims (2)
1. novel valve port compound cement bag comprises oblong bag (1) and seam bottom line (5), it is characterized in that one jiao of end of sack has valve port (3), and this valve port (3) is converted into right-angled trapezium to bag (1) inner chamber concave, and valve port (3) opening is communicated with bag (1) inner chamber; The sack upper end has reinforced sheet (2) to a side cross break, and has sealing line (4) to be connected with sack upper end, reinforced sheet (2), the sewing of valve port (3) upper end.
2. according to the said novel valve port compound cement bag of claim 1, it is characterized in that reinforced sheet (2) rolls over wide 25mm, long 280mm.
