Detailed description of the invention
Please refer to Fig. 3, the packaging bag 20 of one embodiment of the invention forms hermetically-sealed construction by Heat Sealing, can be used for the article such as packaging medicine, food, cosmetics, amenities and workmanship.
This packaging bag 20 is formed by packing such as plastic film materials usually.This packaging bag 20 has the across seal 22 for sealing bags 20 one end.
In a typical structure, the two ends of this packaging bag 20 have an across seal 22 respectively, and middle also have a longitudinal direction to seal (not shown).Bearing of trend and longitudinal bearing of trend sealed of across seal 22 are substantially orthogonal.Wherein the bearing of trend of longitudinally sealing is parallel with the length bearing of trend of the packing provided when forming packaging bag 20, and the length bearing of trend of these packing is also longitudinal direction, also referred to as machine direction (Machine Direction); The bearing of trend of across seal 22 is then parallel with horizontal direction (Cross Direction).As everyone knows, on a production line described in stock production during packaging bag 20, form longitudinal sealing in a longitudinal direction by longitudinal end socket of heat-seal equipment, form across seal 22 by the horizontal end socket of heat-seal equipment along horizontal direction again, and along horizontal direction cut-out across seal 22, former and later two the adjacent packaging bags 20 arranged in a longitudinal direction are separated.
The present invention represents longitudinal direction with the arrow marking MD in figure 3, represents horizontal direction with the arrow marking CD, and the dependency structure of packaging bag 20 of the present invention is showed specifically with the relative position of the packing provided when producing.In packaging bag 20 shown in Fig. 3, the bearing of trend of this across seal 22 is substantially vertical with the length bearing of trend of the packing provided when forming this packaging bag 20, and also namely the bearing of trend of this across seal 22 is substantially vertical with longitudinal direction.Can be known by foregoing description, the definition of across seal 22 and the concrete size of packaging bag 20 have nothing to do, and relevant to the length bearing of trend of the packing in packaging bag 20 forming process.Therefore, in certain embodiments, even if packaging bag 20 has larger length than the length bearing of trend at packing in a lateral direction at packing, these packing formed in a lateral direction remain and be called across seal 22, and non-longitudinal sealing.
Due to the problem because of precision in production process, the length bearing of trend of the packing provided when forming this packaging bag 20 may not completely perpendicular to the bearing of trend of across seal 22.Therefore use " substantially vertical " to state mutual alignment relation between the two herein, this mutual alignment relation should be understood and comprise vertical relation and level off to vertical position relationship in the error allowed band of producing.
This across seal 22 comprises raised line 221 and the groove 222 of alternately arrangement setting successively.The region representation groove 222 with one fixed width between raised line 221, two raised line 221 representing projection in Fig. 3 with lines.It should be noted that, in actual product, this raised line 221 also should have certain width, namely has certain extension size in a longitudinal direction.These raised lines 221 and groove 222 are all arranged in bending.Although raised line 221 and groove 222 are bending, the extension trend of raised line 221 and groove 222 entirety is along horizontal direction.
In certain embodiments, two across seals 22 being positioned at the two ends of packaging bag 20 all can have the setting of this kind of bending raised line 221 and groove 222 interphase distribution.
The raised line 221 of across seal 22 and the bending advantage arranged of groove 222 are, when customer tears the article that packaging bag 20 uses in packaging bag 20, more laborsaving and convenient.Packing for the formation of packaging bag 20 have larger stretching resistance in a lateral direction, and its surface is more difficult than tearing packing along horizontal direction for tearing packing in a longitudinal direction.As shown in Figure 3, two curved arrow represent customer's both hands force direction, and middle straight arrows represents the Impact direction of packaging bag 20.Because raised line 221 and groove 222 are in after bending setting, the raised line 221 that the Impact direction of this packaging bag 20 is bent and groove 222 guide, it is no longer the extension trend completely perpendicular to this raised line 221 and groove 222, thus there are the power of part and the bearing of trend of raised line 221 and groove 222 to be formed and are greater than the angle that 0 degree is less than 90 degree, make to need the horizontal stretching resistance overcoming packing to be completely transformed in being packed by conventional bag and overcome the longitudinal stretching resistance of part and parts transversely stretching resistance, the required total dynamics applied can decline thus.Its concrete manifestation and customer become more easy when tearing across seal 22.
Certainly, in order to further laborsaving, also can be formed at the edge of across seal 22 and be beneficial to the breach 23 tearing across seal 22.These breach 23 indentations, synchronously can be formed when cutting off and be separated former and later two adjacent packaging bags 20.
In embodiment shown in Fig. 3, each raised line 221 and each groove 222 undulate of described across seal 22.Should understand each raised line 221 and not require that entirety is waveform with each groove 222, as long as part, the interlude of such as each raised line 221 and each groove 222 forms waveform, can reach object of the present invention.When the interlude of each raised line 221 and each groove 222 forms waveform, the shape of other parts is unrestricted, such as, can be traditional linear, also can be other curved shape.
In addition, this concrete shape should not be restricted, such as in other embodiments, each raised line 221 of described across seal 22 can be arranged to comprise the broken line be connected successively with each groove 222, and the angle that two adjacent fold-line-shapeds are become is greater than 0 degree is less than 90 degree.This kind arranges and can reduce equally to tear the shearing force needed for across seal 22 or pulling force.Similar, each raised line 221 and each groove 222 not require that entirety is fold-line-shaped, as long as part, the interlude of such as each raised line 221 and each groove 222 forms fold-line-shaped, can reach object of the present invention.When the interlude of each raised line 221 and each groove 222 forms fold-line-shaped, the shape of other parts is unrestricted, such as, can be traditional linear, also can be same as the previously described embodiments or similar waveform etc.
Further, the angle that two adjacent fold-line-shapeds become is greater than 30 degree and is less than 60 degree.Understandably, the angle that two adjacent fold-line-shapeds become should refer to that both intersect that the less angle formed, and this composition graphs 5 when heat sealed package equipment of the present invention is described has further instruction.
In order to make feature instantiation of the present invention clearly, can also be further described from the feature of another one angle to the across seal 22 of packaging bag 20 of the present invention.
