The optimal morphology that carries out an invention
Describe example of the present invention with reference to the accompanying drawings in detail.Fig. 1 is the block diagram of the sealed package 10 of an example of expression the present invention.
(structure of sealed package 10)
The wall 11 of sealed package 10 is made of laminated sheet, and this laminated sheet comprises the substrate layer that has directivity along " specific direction ".So-called among the present invention " specific direction " means this direction in the base material that has directivity on certain 1 direction, in the illustrated embodiment, is " specific direction " along the direction of the imaginary line 30 among Fig. 1 (b).
When constituting sealed package 10 by the mono-sheet material, constitute that the sheet material of packing box 10 is whole to have directivity along " specific direction ", but by as can be known following, in order to realize purpose of the present invention, at least only wall 11 has directivity and gets final product.
Institute's measured length is extended in otch 12 crosscut in wall 11 " specific direction ".Its two ends 12a almost points to the same side (with reference to Fig. 1 (b)) abreast with " specific direction ".Otch 12 runs through wall 11 ground and forms.
Kaifeng covers these otch 12 ground with adhesion seal strip 13 and is attached on the wall 11.Mention Kaifeng adhesion seal strip 13, then the part from otch 12 begins to break, and can form opening 11a as described later on sealed package 10.
As shown in Figure 2, if tear Kaifeng adhesion seal strip 13 to the direction of arrow, wall 11 can begin to break from the part of otch 12, and along cut channel 15 extensions, finally as shown in Figure 3, the part of wall 11 is torn, and forms opening 11a at the position of perimeter 16.
In order to change the direction that breaks, cut channel 15 is located among the near zone A of the perimeter 16 shown in Fig. 1 (a).From the above point of view, cut channel 15 needn't be across the whole surface of wall 11, as long as it is neighbouring just much of that to be present in regional A at least.That is the imaginary line of, being drawn to " specific direction " from otch 12 two ends 30 easily breaks the zone with near the regional A perimeter 16 infalls.This example, forms and easily breaks the zone with the intensity of relief regions A by cut channel 15 is set on sheet material.
Not when imaginary line 30 is provided with cut channel 15 across whole wall 11,, therefore also can tear as illustrated in fig. 3 because wall 11 contains the base material that has directivity along " specific direction ".If just consider, preferably form cut channel 15 across whole wall 11 ground as shown in figure from being convenient to manufacture view.And this moment, cut channel 15 plays the effect of guiding, and the comparable directivity that only relies on base material is torn wall 11 along " specific direction " more reliably.
The sheet material that constitutes sealed package 10 contains the aluminium lamination as isolation layer that forms leak tightness.Concrete sandwich structure has no particular limits, as an example, can be to the order stack of private side according to " unilateral stretching PET (polyethylene terephthalate) layer, printed layers, binding layer, PE (polyethylene) layer, aluminium lamination (isolation layer), articulamentum, CPP layer (not extended polypropylene layer) " from the outside face of packing box.Herein, the unilateral stretching pet layer constitutes substrate layer.
Otch 12 runs through the whole sandwich structure of sheet material, but because Kaifeng covers otch 12 with adhesion seal strip 13, therefore can keep the leak tightness of packing box 10 before breaking a seal.
On the other hand, in order to keep leak tightness, for example can only cut unilateral stretching pet layer and printed layers from the outside face side, form short otch, above-mentioned short otch compartment of terrain linearity is provided with, and constitutes cut channel 15.
As shown in Figure 3, owing to sealed package 10 of the present invention breaks a seal by partly tearing wall 11, so himself does not have sealing function again.Shown in Fig. 4～6, the sealed package 10 that is in open state is contained in the external packing body 50 and uses.In addition, the pinprick shape that so-called cut channel 15 can be a sewing machine, linearity also can be a scar.
(easily breaking other formation in zone)
Among the present invention,, this zone is become easily break the zone, can remove the Kaifeng sheet in this zone for the intensity of sheet material among the relief regions A.Above-mentioned example constitutes and easily breaks the zone by cut channel 15 is set on sheet material, and other example is as described below.
(between substrate layer and sealing layer, be provided with easy peel ply form easily break the zone)
The example of Fig. 7 is provided with easy peel ply between substrate layer that constitutes sheet material and sealing layer in the zone of representing with label 60.
The sheet material that constitutes wall 11 superposes to the order of private side according to " unilateral stretching PET (polyethylene terephthalate) layer, printed layers, weak ラ ミ ニ ス layer, articulamentum, aluminium lamination (isolation layer), articulamentum, CPP layer (not extended polypropylene layer) " from outside face.Herein, the unilateral stretching pet layer constitutes substrate layer, and the CPP layer constitutes sealing layer.
Weak ラ ミ ニ ス layer in the above-mentioned sandwich structure is coating remover and the layer that obtains, the easy peel ply of this layer formation.
Among Fig. 7, by on any interlayer of sandwich structure the intensity that easy peel ply weakens sheet material being set, formation easily breaks the zone.Which position that easy peel ply is superimposed upon in the sandwich structure can suitably be changed.
Bottom line is just enough as long as the zone of strength reduction is present in the zone shown in the A.Calm easily openable opening sheet and the angle that is easy to make are set out, and also can constitute 1 band shape that links 2 regional A but as shown in Figure 7.
(adopt easy peel ply to constitute and easily break the zone) as sealing layer
Though not shown, also can adopt the easy peel ply that shows easy fissility as the most inboard sealing layer in the sandwich structure (easily fissility itself generally is known).At this moment, with cohesion peel off, any form in the splitting, interface peel peels off, and can consider that various conditions suitably determine.
(by laser beam machining on substrate layer, form the sewing machine pinprick form easily break the zone)
In the example of Fig. 8, form sewing machine pinprick 70 on the outermost substrate layer in above-mentioned sandwich structure, weaken the intensity of sheet material thus, form and easily break the zone.
Bottom line herein also is just enough as long as the zone of strength reduction is present in the zone shown in the A.Calm easily openable opening sheet and the angle that is easy to make are set out, and also can constitute the straight line that extends into that links 2 regional A but as shown in Figure 8.And the number of sewing machine pinprick 70 can have only 1 row, also can be multirow.3 row sewing machine pinpricks have been formed in the illustrated embodiment.And,, except utilizing laser beam, need only as the mode that forms sewing machine pinprick 70 with suitable method formation.
Among the present invention, as long as the intensity of the sheet material among the energy relief regions A, therefore concrete formation has no particular limits, and except above-mentioned formation, also can adopt suitable formation in addition.
(external packing body)
Among Fig. 4, thus at first to the direction of arrow 1 tear Kaifeng with adhesion seal strip 13 Kaifeng after, as shown in arrow 2, sealing packaging body 10 is packed in the external packing body 50 into close cap 52 (Fig. 5).
The below part 51 of bearing sealed packaging 10 and cap 52 combine by hinge, constitute external packing body 50, and by not shown spring material both are pressed to closing direction.Be among Fig. 5, below sealed packaging 10 is sandwiched under crimped status between part 51 and the cap 52.
In a word, the door leaf 55 that forms movable platen is in " off position " in Fig. 5, be in " open position " in Fig. 6.
Because opening 11a extends to its periphery near the wall central authorities of packaging body 10, when therefore taking out hygenic towelette 20, can take out hygenic towelette simply by mentioning its ora terminalis 20a.
After taking out hygenic towelette 20, only need close door leaf 55 and get final product, door leaf 55 is pushed down sealed packaging 10 with covering its opening 11a, therefore can reproduce and keep the sealing state of packaging body 10 well.
That is, no longer need to resemble and compressed the troublesome operations of adhesion sealing band meticulously in order to reproduce sealing state the former closing bag.
In addition, show the structure of external packing body 50 in the drawing briefly, but the mechanism particularly make sealed packaging 10 location that hold and the interior shape of door leaf 55 preferably suitably are set, so that the whole opening 11a of airtight well sealed packaging 10.
