Abstract

The invention provides a bag in barrel with an inner bag and an outer barrel for a liquid container. The bag is used in a barrel, the inner bag cannot be distorted during filling, and liquid can be quickly and conveniently filled in the bag. The bag comprises an inner bag body, and is characterized in that: the inner bag body is formed by splicing at least three polyhedral films; a bag opening of the spliced inner bag is encircled by two sides, which are positioned on the uppermost part, of two adjacent films; the ends of two sides of the spliced inner bag are formed by connecting the ends, which are positioned on the same side, of all the films; and the two ends of the inner bag are higher than the bottom of the unfolded inner bag.

Description

Liquid type container with inner bag and outer bucket is used in the bucket with bag

Technical field

The present invention relates to the parts of the packing container of liquid, be specially liquid type container and use in the bucket with bag with inner bag and outer bucket.

Background technology

Bag in the bucket, a kind of novel package form as pure water, grape wine, fruit drink, edible wet goods liquid has obtained application more and more widely.Bag comprises inner bag and outer bucket in the bucket, and inner bag is processed by soft materials such as plastic sheetings, and outer bucket is meant the sealing bucket of the band oral area of the hard of processing with various metallic materials or non-metallic material.The direct packing liquid of inner bag, disposable use; Outer bucket provides rigidity to be beneficial to transportation and storage as the external packing of inner bag, and is reusable.

A kind of typical application of bag is a drummed pure water in the bucket, has the bucket of soft inner bag, is wrapped in after the oral area of soft inner bag turns up on the bung and also uses the bung component package, is provided with air extractor vent in the bottom of bucket.During use, utilize the pressure that gets into the air the bucket from air extractor vent, water is flowed out from inner bag.This patent is compared with traditional bucket that does not use inner bag, has to keep for a long time that pure water never degenerates, the characteristics of safety and sanitation, but this structure; At the bottom of bucket, open pore, destroyed the structure of bucket, reduced the intensity of bucket; And dust can get in the bucket from air extractor vent, and is not dustproof.Now adopt a kind of new manner of packing in the industry; Be exactly not punch at outer barrel bottom, through the pore that the bag mouth of installing at the inner bag oral area is provided with, make air from pore get into inner bag with outside barrel between; Form and the extraneous gas passage that is connected, realize discharging liquid in the bag.The advantage of this mode is to need not to offer air extractor vent on the outer bucket, and structural integrity also keeps its original intensity; But its shortcoming is exactly in canned process, and a bag bucket content outside is prone to distortion because inner bag normally the plastic film heat seal of whole piece form, it is plane that bag is generally, and normally sack carried when canned, the bag body folded fill in outer bucket, canned then.So just exist liquid to carry out to strut two angles of its in-to-in when canned, cause the inner bag distortion, canned difficulty.

Summary of the invention

To the problems referred to above, the invention provides liquid type container with inner bag and outer bucket with in the bucket with bag, use it in the bucket, distortion can not appear in inner bag when canned, liquid can the fast speed filling bag in, canned convenience.

Liquid type container with inner bag and outer bucket is used in the bucket with bag; Its technical scheme is such: it comprises the inner bag body; It is characterized in that: the inner bag body has at least three multiaspect shape films assembled; The sack of the inner bag that assembly unit is good is exactly that adjacent two films two limits being positioned at topmost surround, and the both side ends of the inner bag that assembly unit is good is respectively to be formed by connecting the end that all above-mentioned films are positioned at the same side, and the both ends of said inner bag are higher than the bottom after said inner bag launches.

It is further characterized in that: the inner bag body is assembled by the four sides film; Described four sides film becomes octahedral shape respectively; In the film of described four sides, during the assembly unit end, two faces that are parallel to each other, it is positioned at outermost limit, the amalgamation each other of interlude part, the outermost limit amalgamation of that face film that the remainder of both sides is adjacent respectively about being positioned at.

Be placed in the outer bucket the present invention is folding, sack is stayed bung, when canned; Liquid charges into inner bag fast, because by at least three film amalgamations, and the height of film end assembly unit is higher than the bottom of inner bag; But at high speed strutted inner bag after liquid charged into like this; Inner bag is launched, prevented the distortion of inner bag, easily and fast canned.

Description of drawings

Fig. 1 is the main structural representation of looking of the present invention;

Fig. 2 is a left view of the present invention among Fig. 1;

Fig. 3 is the outside drawing of film among the present invention;

Fig. 4 is the structural representation of inner bag body 1 end film amalgamation of the present invention.

The specific embodiment

Like Fig. 1～shown in Figure 3, the present invention includes inner bag body 1, inner bag body 1 is assembled by at least 3 multiaspect shape films 2, and among Fig. 2, inner bag body 1 is assembled by four sides film 2; Film 2 becomes octahedral shape (see figure 3) respectively; The sack 4 of the inner bag that assembly unit is good is exactly that adjacent two films two limits being positioned at topmost surround; The both side ends of the inner bag that assembly unit is good is respectively to be formed by connecting (seeing Fig. 1, Fig. 2) the end that film is positioned at the same side, and the both ends of inner bag 1 are higher than the bottom after inner bag 1 launches.

In the film 2 of four sides, during the assembly unit end, two faces that are parallel to each other; Be the face that is in vertical angles among Fig. 2, it is positioned at outermost limit, the mutual amalgamation (see figure 4) of interlude 3 parts; Form bonding part 5; Be positioned at the outermost limit amalgamation of that face film that the remainder of interlude both sides about in the of 3 is adjacent respectively, form bonding part 6, bonding part 6 overlaps with film piece 7 in Fig. 2.

Claims
