Abstract
The packing tube that a kind of membraneous material is rolled into is an edge that forms barrel-contoured film, and its inner face is bonded into behind the state of putting the palms together before one each other with the first weld line welding.The film that two film edge partial sums that extend to the outside from this first weld line constitute packaging bodies together, with the second weld line welding.In this packing tube filling processing carnivorous and so on after with its closed at both ends.The part of above-mentioned second weld line is interrupted, and just can break the film that forms packing tube by tearing in this section, and film is easily peeled from content.
Description
The present invention is filled to packing material in the cylindrical thin-film, the cylindrical thin-film packing material that the customer is opened easily with processed foods such as sausage or cheese.
Figure 11 the has represented filling example of prior art of cylindrical thin-film packing material of processed food such as sausage.
This packing material is shown in the section-drawing of Figure 12, two the marginal portion 1a and the 1b of the membraneous material 1 of inferior chlorovinyl series and so on is overlapping, with dielectric bonding or ultrasonic brazing unit etc. the lap welding is formed weld line S, form packing tube 10a cylindraceous thus.When making sausage, arriving in this packing tube 10a cylindraceous of the carnivorous filling of processing, and when making rod shape cheese, process cheese is filled in the packing tube 10a cylindraceous, then two ends of packing tube 10a length direction are received to disturb and tie tight, and tighten sealing with metal clamps 2 such as aluminium.
When making sausage, will process meat be filled to packing tube 10a interior after, just be transferred to cooking process.Because the internal pressure of packing tube 10a raises in cooking process, has produced tension force on membraneous material 1, the direction of this tension force shown in arrow F among Figure 12 is to weld line S generation effect.And in this prior art example, as shown in figure 12, membraneous material marginal portion 1a and 1b are almost mutually with flat state weld together overlappingly, though the power of representing with arrow F that tension force produced by membraneous material works to weld line S, but because the weld strength of weld line S is enough high concerning this power F, in cooking process, packing tube 10a also still is that difficulty is broken.
Yet during membraneous material 1 on will tearing above-mentioned cylindrical thin-film packing material, except catching with finger from the outwards outstanding membraneous material marginal portion 1a of weld line S, not having can be for the start-up portion that tears weld line S.And, catch this membraneous material marginal portion 1a to determine very difficulty with finger owing to the marginal portion 1a that gives prominence to the membraneous material outside packing tube 10a is very short, therefore, it is just impossible to tear membraneous material from membraneous material marginal portion 1a.Like this, when the customer will tear membraneous material, just must on membraneous material 1, open a kerf earlier, then this otch be torn membraneous material as start-up portion, and then it is peeled from packaged object with pocket knife and so on instrument.Like this, in the past, when not having pocket knife and so on instrument at one's side, it is very difficult membraneous material being peeled from packaged object.
In addition, resemble cylindrical thin-film packing material rod shape cheese and so on, smaller, the Kaifeng band of dying color such as red is housed usually, draw this Kaifeng band just can make on the membraneous material 1 and produce cut.But, because the band that breaks a seal than other film for packaging material price height, uses to longer size the existing packing material of the band that breaks a seal so also just uneconomical because of the cost height.In addition, be used for the Kaifeng band on the packing materials such as rod shape cheese in the past, normally along being provided with endlong on the cylindrical thin-film packing material length direction, its two ends are tightened with membraneous material 1 together by clamp, therefore the Kaifeng band when packing tube 10a draws back, its two ends can win over clamp 2.Make whole packing tube 10a bow, the shortcoming that makes the packed article body deformability is arranged.
The objective of the invention is to solve above-mentioned existing in prior technology problem, a kind of cylindrical thin-film packing material (packaged object is contained in the packing tube, and two ends are tightened) is provided.This packing material also can easily be torn membraneous material even without dress Kaifeng band.And the weld strength of membraneous material marginal portion is also very high, can stand when making sausage the rising in its internal pressure of cooking process fully.
The present invention is two marginal portion welding with membraneous material, form packing tube cylindraceous, processed food is filled in this cylindrical package tube, simultaneously the closed at both ends on the packing tube length direction is made packaging film, it is characterized in that: two marginal portions of above-mentioned membraneous material are fitted the shape degree of putting the palms together before one that joins each other with the continuous two sides of the inside face of packing tube, and weld by first weld line, to be fitted in together on the outside face of packing tube from two marginal portions of the outward extending membraneous material of first weld line again, and by second weld line with two marginal portions of membraneous material with forms the membraneous material weld together of packing tube, and formation does not have soldered discontinuities on one section of this second weld line.
In addition, in foregoing invention,, on the edge of membraneous material, have breach (otch) in the discontinuities of second weld line.
Catch the membraneous material marginal portion of the discontinuities (do not have when welding soldered that part of) of second weld line of this cylindrical thin-film packing material with second weld line with finger, and its strip off, just can be two marginal portions that are welded on the membraneous material on the packing tube outside face from the second weld line strip off; Also can from the first weld line strip off, can make two marginal portions of membraneous material on the membraneous material that constitutes this part packing tube and produce cut according to different situations.Like this, two of membraneous material marginal portions can be brought into play with the Kaifeng that is installed separately with the membraneous material that constitutes packing tube in the prior art with roughly the same effect.By the marginal portion of strip off membraneous material, with regard to the membraneous material of tearable bale broken fitted tube, thereby just can be as with the start-up portion of membraneous material from the strip off of packed article surface.In addition, be preferably in gap (otch) on the membraneous material marginal portion of discontinuities of second weld line, like this, marginal portion that just can this part tear fracture membraneous material makes that the membraneous material marginal portion is easier to peel from packing tube.
In addition, since two marginal portions of membraneous material by first weld line with it inside face each other phase ground connection fit and become to put the palms together before one state ground weld together, then again by second weld line from the outside face weld together of two marginal portions of the outward extending membraneous material of first weld line with packing tube, it is quite high that the weld strength of membraneous material just becomes.Thus, even in the operations such as boiling when making sausage, producing under the situation of tension force on the membraneous material because of the internal pressure of packing tube raises, weld zone also can bear this tension force fully.

Below, to cylindrical thin-film packing material shown in Figure 1 (packaged object has been filled in the packing tube 10, and the packing material tightened of two ends), the example that membraneous material 1 is peeled the action that comes from the packed article surface is illustrated.
At first, catch the second weld line S with finger
2Discontinuities on, from two marginal portion 1a and the 1b tear fracture of breach 3 with membraneous material.Then as shown in Figure 5, along weld line S
1And S
2Pull two the marginal portion 1a and the 1b of membraneous material, they are torn it down with membraneous material 1 with becoming band discretely, thus the membraneous material 1 of packing tube 10 is torn.Its detailed process is, earlier by pulling two marginal portion 1a, 1b of membraneous material, that part of the staving of representing with arrow A among Fig. 3.Also be, because with respect to double-layer films material with two marginal portion 1a, 1b pointing the membraneous material that pulls, packing tube 10 1 sides are thin film material layers, by pulling two marginal portion 1a, 1b of membraneous material, the thin film material layer 1 of packing tube 10 1 sides is just at weld line S
2Part pulled open.Subsequently, pull two edge 1a, 1b of membraneous material, the weld line S that in Fig. 3, represents with arrow B
1Two marginal portion 1a, 1b of part membraneous material also separate with the membraneous material 1 of packing tube 10.Thus, as shown in Figure 5, two marginal portion 1a, 1b of membraneous material are torn with becoming band.According to different situations, A portion not only sometimes, even cut also appears at the membraneous material 1 of the formation packing tube 10 of B portion.Therefore, when two marginal portion 1a of membraneous material and 1b were torn it down with becoming band, the cut that constitutes the membraneous material 1 of packing tube 10 just enlarged, and packaged object is exposed.
In order to peel the membraneous material 1 on the cylindrical thin-film packing material, method shown in Figure 6 also is an actv..This method be earlier with finger from breach 3 two edge 1a of membraneous material and 1b tear fracture, then with among marginal portion 1a, the 1b of membraneous material with that part ofly tearing that D represents, as that part of the staving of above-mentionedly the membraneous material 1 that constitutes packing tube 10 being represented with A from Fig. 3 at least from packing tube 10.After this, press the end of packing material again with finger, packaged object is expanded, as shown in Figure 6, the rent of membraneous material 1 just enlarges, thereby packaged object is exposed.
Fig. 5 and method shown in Figure 6 be an example of the Kaifeng method of packing material shown in Figure 1 only, in addition, also can use other any methods Kaifeng.That is to say, by from weld line S
2Marginal portion 1a, the 1b of breach 3 tear fracture membraneous materials of discontinuities l, can be at an easy rate with membraneous material 1 strip off of packing tube 10.
Fig. 7 and Fig. 8 represent second embodiment of the present invention.
This embodiment is at the second weld line S
2Discontinuities l on be not arranged on the breach of representing with label 3 among Fig. 1.Yet even breach 3 is not set, the operation of strip off membraneous material 1 also still is easy to.An example of this method is to catch the second weld line S with finger earlier
2Marginal portion 1a, the 1b of membraneous material of discontinuities l, thus weld line S
2A part, according to different situations, sometimes also at weld line S
1A part on membraneous material 1 tear fracture of packing tube 10, expose packaged object.Like this, even without the structure that breach is set, the operation of strip off membraneous material 1 also is easy.
Among the embodiment of above-mentioned Fig. 1～shown in Figure 8, the membraneous material marginal portion 1a and the 1b that constitute packing tube 10 are by the first weld line S
1With the second weld line S
2, weld at Liang Chu.As shown in Figure 2, only marginal portion 1a, the 1b with membraneous material fits each other with putting the palms together before one, with a weld line S
1Under the situation of welding, bear the weld line S of the direction power shown in the arrow F
1Weld strength lower.For this reason, in the above-described embodiments, as shown in Figure 3, at the first weld line S
1The basis on added the second weld line S again
2, thereby improved weld strength.So during as the making sausage, be transferred to cooking process after packing finishes, along with the rising of internal pressure, the suffered tension force of membraneous material also increases, even the power of F direction is all acted on the weld zone, it also has enough intensity.That is to say, when the marginal portion of membraneous material 1a, 1b only fit and each other with a weld line S with putting the palms together before one
1During welding, the power F that is formed by the suffered tension force of membraneous material is as making the edge 1a of membraneous material and power that 1b tears each other work weld line S
1Just disconnect easily.But, adding the second weld line S
2Situation of the present invention under, at the second weld line S
2The place makes marginal portion 1a, the 1b of membraneous material and the membraneous material 1 of packing tube 10 be in closely weld together of overlapped state, above-mentioned power F just works in the direction that membraneous material will be staggered mutually, therefore, only can not make the second weld line S with this power F
2Disconnect.By the second weld line S
2With the first weld line S
1The two combined action, the intensity of weld zone has just been improved significantly.
In addition, make under the higher situation of the intensity of weld zone at needs, as shown in Figure 9, the membraneous material band 6 that strengthens usefulness can be clipped between the marginal portion 1a and 1b of membraneous material, this membraneous material band 6 can be welded on weld line S together with marginal portion 1a, 1b
1And S
2On.Can be previously used Kaifeng band as this membraneous material band 6.Like this, strengthen with membraneous material band 6, just can be increased in weld line S owing to used
1And S
2The film number of plies of place welding also just can improve the weld strength of dielectric bonding etc.Perhaps, as shown in figure 10, the membraneous material band 6 that strengthens usefulness is attached to the outside of the marginal portion 1a of membraneous material, by membraneous material band 6 is welded on weld line S
1And S
2On, just can improve the intensity of weld zone.
If use above-mentioned the present invention, owing to put the palms together before one each other and snugly weld together in two marginal portions of the thin-film material of formation cylindrical package tube, the marginal portion that makes simultaneously thin-film material forms second sealing wire along the thin-film material outer surface of packing tube, and be provided with discontinuities a certain section of second sealing wire, thereby just can catch with finger the marginal portion of thin-film material of the discontinuities of second sealing wire, with its strip off, also just can easily thin-film material be broken, make thin-film material be easy to peel from packaged object. In addition, owing to formed two sealing wires, with only two marginal portions of thin-film material being compared with the situation of a sealing wire welding each other with putting the palms together before one, the intensity of welding portion is improved, therefore, when making sausage, in cooking process, even inner pressure raises, packing tube does not destroy from welding portion yet.
