Abstract
The utility model discloses a flexible freight bag which comprises a bag body (1) provided with a feeding port (1). The lower portion of the bag body (1) is provided with multiple base plates (2) formed by splicing and sealing in a hot-pressing mode, the bottom portion of a conical bag bottom (3) is folded towards the upper end of the bag body (1) to form an inner sharp corner (31), and a sealing adhesive tape (4) is bonded on the outer wall of the conical bag bottom (3) located at the root position of the inner sharp corner (31). The sealing adhesive tape (4) consists of a transverse adhesive tape (41) and a vertical adhesive tape (42) which are arranged in a cross mode. The bag body (1) and the base plates (2) are of multiple-layer structures consisting of polyethylene glycol terephthalate layers, aluminum foil layers, nylon layers and polyethylene layers which are sequentially superposed and compounded from outside to inside. The flexible freight bag has the advantages of being good in bottom impact resistance capacity, not prone to crack and damage, long in service life, high in structural strength and good in humidity resistance.
Description
Technical field
The utility model relates to containers field, is specifically related to a kind of jumbo bag.
Background technology
The conventional collection in market fills plastic grain class at present, powdery type jumbo bag is efficient and convenient because of its pack bleed, is usually widely used by enterprise.As shown in Figure 1, the jumbo bag of prior art comprises the bag 1 with inlet point 11, and the bottom of bag 1 is provided with the bag flat 21 being spliced to form by hot-press sealed by multiple base plates 2.But in use there are a lot of shortcomings in existing jumbo bag, for example ought be in use in earlier stage in the process of bag 1 inflating pressure or charging, because bag flat 21 is spliced to form by hot-press sealed by multiple base plates 2, the hot-press sealed place of its bottom is hot-press sealed, therefore usually can not bear huge suddenly impulsive force because of the hot-press sealed place of flat 21 bottoms of bag and produce the phenomenon of bag bottom explosion, make enterprise reduce in use production efficiency, increased enterprise cost.
Utility model content
The technical problems to be solved in the utility model be to provide the shock-resistant ability in a kind of bag bottom strong, be difficult for explosion breakage, long service life, structural strength is high, anti-soak properties are good jumbo bag.
A kind of jumbo bag, comprise the bag with inlet point, at the bottom of the bottom of described bag is provided with the cone-shaped bag being spliced to form by hot-press sealed by multiple base plates, bottom at the bottom of described cone-shaped bag forms square corner to bag upper end turnover, and at the bottom of described cone-shaped bag, is positioned on the outer wall at square corner root place and is pasted with sealing tape.
Described sealing tape is made up of the horizontal adhesive tape and the vertical adhesive tape that are square crossing layout.
Described bag, base plate are the multiple-structure being made up of polyethylene terephthalate layer, aluminium foil layer, nylon layer, polyethylene layer superimposion successively from outside to inside.
Jumbo bag of the present utility model has following advantage: the utility model is owing to making the bottom at the bottom of cone-shaped bag form square corner to the turnover of bag upper end, and at the bottom of cone-shaped bag, be positioned on the outer wall at square corner root place and be pasted with sealing tape, therefore when in to the process of bag inflating pressure or charging, can reduce sudden surge power to cone-shaped bag at the bottom of the impact at hot-press sealed place of bottom, thereby can prevent from causing due to impact the explosion at the hot-press sealed place of bottom at the bottom of cone-shaped bag, have advantages of that the shock-resistant ability in bottom is strong, be difficult for explosion breakage, long service life.

Fig. 4 is the local structure for amplifying schematic diagram of bottom at the bottom of the cone-shaped bag of the utility model embodiment.
Marginal data: 1, bag; 11, inlet point; 2, base plate; 21, bag is flat; 3, at the bottom of cone-shaped bag; 31, square corner; 4, sealing tape; 41, horizontal adhesive tape; 42, vertical adhesive tape.
The specific embodiment
As shown in Figures 2 and 3, the jumbo bag of the present embodiment comprises the bag 1 with inlet point 11, the bottom of bag 1 is provided with at the bottom of the cone-shaped bag being spliced to form by hot-press sealed by multiple base plates 23, at the bottom of cone-shaped bag, 3 bottom forms square corner 31 to bag 1 upper end turnover, and at the bottom of cone-shaped bag, is positioned on 3 on the outer wall at square corner 31 root places and is pasted with sealing tape 4.The present embodiment due to cone-shaped bag at the bottom of 3 bottom form square corner 31 to bag 1 upper end turnover, and at the bottom of cone-shaped bag, be positioned on 3 on the outer wall at square corner 31 root places and be pasted with sealing tape 4, therefore work as in the process of bag 1 inflating pressure or charging, can reduce the impact at the hot-press sealed place to 3 bottoms at the bottom of cone-shaped bag, thereby can effectively prevent from causing due to impact the explosion at the hot-press sealed place of 3 bottoms at the bottom of cone-shaped bag, have advantages of that the shock-resistant ability in bottom is strong, be difficult for explosion breakage, long service life.
As shown in Figure 3 and Figure 4, the sealing tape 4 in the present embodiment is made up of the horizontal adhesive tape 41 and the vertical adhesive tape 42 that are square crossing layout.Laterally adhesive tape 41 and vertical adhesive tape 42 are square crossing and arrange, make sealing tape 4 more solid and reliable with the outer wall bonding of 3 bottoms at the bottom of cone-shaped bag, thereby can strengthen the shock-resistant ability at the hot-press sealed place of 3 bottoms at the bottom of cone-shaped bag.
In the present embodiment, bag 1, base plate 2 are from outside to inside successively by polyethylene terephthalate (PET) layer, aluminium foil (AL) layer, nylon (NL) layer, polyethylene (PE) are stacked and add the compound multiple-structure forming.Above-mentioned multiple-structure can strengthen at the bottom of bag 1 and arc bag 2 structure, has advantages of that structural strength is high, anti-soak properties good.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
