Description

Easy-open package

Technical field

The present invention relates to a kind of easy-open package, more specifically, relate to a kind of easy-open package that can be also used as horizontal vessel and vertical vessel use.

Background technology

In having held the flexible packaging body of the content that as wet tissue, contains moisture, discussed such flexible packaging body, its taking-up easy to carry, easy, and the drying when preventing to reuse the residue wet tissue and can sealing once again.As such flexible packaging body, for example, Japan is real to open in clear 59-No. 99974 communiques, records: form otch and form peristome in the bag main body, face is provided with inclosure bag strippable cover, cosmetic lamination coating etc. by lining cement from it; A kind of peristome and its peristome leak free film flexible packaging body once again that has is also disclosed.

In addition, also discussed the scheme that makes up above-mentioned flexible packaging body and hold the rigid container of wet tissue; For example, 2003-No. 170950 communiques of TOHKEMY disclose such packaging body: it is made of film like flexible packaging body and rigid container, it is folding and with plane wet tissue after stacked that this film like flexible packaging body holds the wet tissue that will be cut open one by one, this rigid container holds this flexible packaging body in the mode of horizontal placement, makes its wet tissue plane become level; Rigid container is to be called the container that what is called is pushed to formula, and its container top board has conveying end, and this conveying end is used to extract out the wet tissue sheet and can takes out the wet tissue sheet continuously.This rigid container is owing to the conveying end that is provided with wet tissue at the top board center of container, so the peristome of flexible packaging body also is located at the center.

On the other hand, as the rigid container that holds wet tissue, in 8-No. 104377 communiques of Japanese kokai publication hei, disclose such rigid container: the folding and stacked wet tissue sheet that is cut open one by one, directly hold this wet tissue sheet so that the wet tissue sheet is the mode of plumbness; This rigid container has from being disposed at conveying end on the container top board pulls out the structure of thin slice.

As 2003-No. 170950 communiques of TOHKEMY, hold the flexible packaging body of wet tissue and hold under the situation of outer packaging container of rigidity of flexible packaging body in combination, must use the position of the peristome of flexible packaging body to meet the flexible packaging body of each rigid container peristome.For example, if common traverse form, then in the flexible packaging body and the cooresponding position of the substantial middle portion wet tissue plane, it is just passable to form ellipticity or tetragonal circular opening., under vertical situation of putting, consider that corresponding with it when the peristome of outer packaging container forms above it, the peristome of flexible packaging body also is formed on packaging body end from above-mentioned substantial middle portion to the top for well from the taking-up angle of wet tissue.

Like this, for example, even application target is similar, the identical thin slice of content (soup or nonwoven fabrics, size), because of the placement form difference of traverse or the vertical outer packaging container of putting, the customer must buy and be fit to the special product of the flexible packaging body of the refitting usefulness of shape separately, very inconvenience.

; in as the real flexible packaging body of opening in clear 59-No. 99974 communiques, 2003-No. 170950 communiques of TOHKEMY, 8-No. 104377 communiques of Japanese kokai publication hei in the past of above-mentioned Japan; because its placement form is to have determined to be traverse or vertical putting; so, also do not have the investigation wet tissue flexible packaging body of its both sides' of correspondence refitting form simultaneously.

In addition, in this specification sheets, " surperficial substantial middle portion " of packaging body is meant near the central portion of the packaging body upper surface side of placing in the plane under the packaging body state, for example, in the pillow package body, preferably with the central part of the face of face opposition side with back side mouth-sealed portion near.In addition, " the substantial middle portion " of so-called packaging body is meant the substantial middle portion on above-mentioned surface or any one in the back side substantial middle portion; So-called " its periphery " is meant the zone except substantial middle portion.

In addition, in this manual, the end that forms packaging body second peristome one side is " end ", and the end that does not form second peristome, one side is " the other end ".And so-called " end " is meant any periphery of packaging body, preferably thermal welding portion (mouth-sealed portion).For example, has back side mouth-sealed portion and up and down in the pillow package body of mouth-sealed portion, preferably a side (for example, last mouth-sealed portion) of mouth-sealed portion is " end of packaging body " up and down, the opposing party of mouth-sealed portion (for example, lower seal oral area) is " the other end of packaging body " up and down.

(2) in the described easy-open package of technical scheme (1), the described first Kaifeng line that described first peristome forms means is a ring-type; The described second peristome formation means are to be made of the second Kaifeng line and cover, this second Kaifeng line comprises two lines that extend towards a described end side from the described first Kaifeng line, and described cover covers described first Kaifeng line and the described second Kaifeng line simultaneously; On described cover, be formed with cut-off rule in the position of cutting apart the described first Kaifeng line and the second Kaifeng line.

According to this mode,, cover can be divided into two and it is peeled off by on a cover, forming cut-off rule.And, at this moment, under the situation of only peeling off the cover that comprises first Kaifeng line one side from cut-off rule, form first peristome of ring-type.In addition, under the situation of only peeling off the cover that comprises second Kaifeng line one side from cut-off rule, till packaging body one end, be stripped from, form second peristome from the second Kaifeng line.

In addition, so-called " ring-type " is meant that it all is the osed top line.Line itself can be a continuous lines, also can be to be interrupted wire.In addition, its shape can suitably be selected shapes such as circle, ellipse, quadrangle, does not limit." two lines that extend towards an end side from the first Kaifeng line " are meant the direction of such formation: peeled off under the situation of cover, and continuous from the first Kaifeng line of ring-type, and can flexible packing material be stripped from by the second Kaifeng line.It can be a straight line, also can be curve, also can be wave or rectangular lines.

In addition, so-called " position of cutting apart the first Kaifeng line and the second Kaifeng line " is meant under the separated situation of the first Kaifeng line and the second Kaifeng line, though preferably be positioned between the two, also can comprises a part first Kaifeng line and/or the second Kaifeng line.In addition, do not have under the separated situation at the first Kaifeng line and the second Kaifeng line, can make cutting plate separately comprise a part first Kaifeng line and/or the second Kaifeng line, still, preferably the second Kaifeng line is configured to exist only at least one side's the cutting plate.

(3) in the described easy-open package of technical scheme (2), the described second Kaifeng line be two terminal point towards the コ of described end word shape, the described first Kaifeng line conllinear of one partial sum.

According to this mode,, the first Kaifeng line and the second Kaifeng line can be set in less area by making the first Kaifeng line and the second Kaifeng line part conllinear.

(4) in technical scheme (2) or the described easy-open package of technical scheme (3), described cover periphery and described cut-off rule intersect near, be formed with second from described cut-off rule in a described end side and peel off beginning portion; Be formed with first in the other end described cover periphery, described packaging body side and peel off beginning portion.

According to this mode, when first peels off portion's peel-off covers parts, be stripped to the part of the cut-off rule that comprises the first Kaifeng line in the cover, only form first peristome of ring-type.In addition, peel off the position when peeling off since second, be stripped to an end of packaging body, form the second bigger peristome from the second Kaifeng line.

In addition, the what is called in this specification sheets " is peeled off beginning portion " and is meant the part as the beginning that is used to begin to break a seal, and is the part that can take easily with hand.Specifically, for example can enumerate the part that the back side does not have adhesive-applying as cover " peeling off beginning portion ", " peeling off beginning portion " as packaging body can enumerate, be formed at the otch or the known easily openable means (for example, in the part of mouth-sealed portion) of an end or the other end of packaging body with the fine scar of planar formation.

(5) in technical scheme (2) or the described easy-open package of technical scheme (3), described cover periphery and described cut-off rule intersect near, be formed with second from described cut-off rule in a described end side and peel off beginning portion; Described cover periphery and described cut-off rule intersect near, be formed with first from described cut-off rule in the other end of described packaging body side and peel off and begin the position.

According to this mode, when first peeled off portion's peel-off covers parts, the cut-off rule that only comprises the first Kaifeng line in the cover was stripped from, and only forms first peristome of ring-type.In addition, when second portion of peeling off peels off, be stripped to an end of packaging body, form the second bigger peristome from the second Kaifeng line.

(6) in the described easy-open package of technical scheme (1), described first peristome forms the described first Kaifeng line of means, is to peel away initial line and peel off a pair of line that stop line constitute relative with it by what be positioned at a described end side; Described two terminal points peeling off stop line are positioned at described foreign side of peeling away initial line; The described stop line double as of peeling off is the described second Kaifeng line that described second peristome forms means.

According to this mode, it is shared in the first Kaifeng line and the second Kaifeng line to peel off stop line.And, during from an end side of packaging body Kaifeng cover, peel off to peeling off stop line from peeling away initial line, two terminal points peeling off stop line are positioned at the foreign side of peeling away initial line, so peel off stop line in arrival just, peel off end, form first peristome of ring-type.On the other hand, during from the other end side Kaifeng cover of packaging body, tear line is with to peel away initial line irrelevant, and former state arrives an end of packaging body unchangeably and forms the second bigger peristome.In addition, the what is called in this specification sheets " foreign side " is meant a side and the opposing party's end direction of packaging body.As the shape of " a pair of first Kaifeng line ", can enumerate, form the shapes such as vee shape, コ font, U font of convex to the both end sides of packaging body.

(7) in the described easy-open package of technical scheme (1), the described first Kaifeng line that described first peristome forms means is to peel away initial line and peel off a pair of line that stop line constitute relative with it by what be positioned at a described end side; Described two terminal points peeling off stop line are positioned at described foreign side of peeling away initial line; The described initial line of peeling away is the line of two terminal point towards the other end of described packaging body; The described second Kaifeng line that described second peristome forms means is two lines peeling away initial line to described end side extension from described.

According to this mode, when the end side from packaging body breaks a seal cover, by a pair of first Kaifeng line, from peeling away initial line to peeling off first peristome that stop line forms ring-type.In addition, when the opposing party's end side from packaging body broke a seal cover, the side's end side from the second Kaifeng line to packaging body formed the second bigger peristome.

(8) in the described easy-open package of technical scheme (1), the described first Kaifeng line that described first peristome forms means is a ring-type; Described cover has the beginning of peeling off portion in a described end side; Be formed with non-weld portion in a described end; The described second Kaifeng line that second peristome forms means is the Kaifeng line that is formed at the pair of parallel on the described non-weld portion.

According to this mode, when forming second peristome, catch between the Kaifeng line of pair of parallel of the non-weld portion that is formed at packaging body one end and mention, thus, zone from non-weld portion side is downcut almost parallel to surperficial substantial middle portion can form from the second continuous peristome of an end of packaging body.

(9) in the described easy-open package of technical scheme (8), the distance between the Kaifeng line of described pair of parallel is less than the width of described first peristome.

According to this mode, the first peristome zone then, is also downcut along the first Kaifeng line in the zone of having downcut almost parallel from non-welding position, thereby as second peristome, can form from the end of packaging body to the continuous bigger peristome of first peristome.In addition, so-called " width of first peristome " be meant in first peristome, along the extreme length of the direction an of end of packaging body and the other end.

(10) in the described easy-open package of technical scheme (8), the distance between the Kaifeng line of described pair of parallel is greater than the width of described first peristome; And have two lines that extend to a described end side from the described first Kaifeng line.

According to this mode, the zone of having downcut almost parallel from non-welding position, then, because two above-mentioned lines, tear temporarily and stop, arriving the first Kaifeng line via these two lines further, the result, the zone of first peristome is also by down, thereby as second peristome, can form end from packaging body to the continuous bigger peristome of first peristome.In addition, because two above-mentioned lines can enlarge the interval of the Kaifeng line of a pair of almost parallel, so can form the second bigger peristome.

(11) in technical scheme (1) to the technical scheme (3) in each described easy-open package, an end of described packaging body is the heat-sealing oral area of easily openable.

According to this mode, by an end of packaging body being made the heat-sealing oral area of easily openable, when forming second peristome, can tear simply to the end and remove diaphragm.At this, so-called " the heat-sealing oral area of easily openable " can utilize known in the past, as to reduce heat-sealing mouthful intensity method, for example, as the sealant layer of film as long as utilize film with easy openability.

(12) in technical scheme (1) to the technical scheme (3) in each described easy-open package, described packaging body is a sealed packaging, the content of this packaging body is a wet tissue.

According to this mode, the wet tissue of refitting usefulness is contained in the common pillow package body, needs from then on to take out simply wet tissue, and, particularly need bigger peristome.On this point, if easy-open package of the present invention just can form bigger peristome, even outer packaging container be vertical placement, laterally place any one also can easily take out wet tissue.In addition, owing to be sealed packaging, so can prevent the content drying of wet tissue etc.

In the present invention, when having peeled off cover, be preferably on the flexible packing material means of inducing of tearing that the guiding flexible packing material tears that form, so that it forms the continuous peristome in an end from second peristome to packaging body by the second Kaifeng line.According to this mode, owing on flexible packing material, formed the means of inducing of tearing, so form bigger peristome easily from the terminal point of the second Kaifeng line to packaging body one end.

In addition, the terminal part that comprises the terminal point of " two lines that extend to an end side of packaging body " be preferably formed as into: angle angle, a described stripped end side between its line parallel with the cover direction of delaminate is less than 90 °.According to this mode, owing to second terminal point that breaks a seal line forms towards direction of delaminate, so the direction of bootable Tear Film.Therefore, film is torn with certain orientation, stably forms peristome.In addition, " second Kaifeng line " in this mode do not having specific restriction in shape, can be that the combination by straight line, curve and the straight line of or two or more forms, but the part that comprises terminal point forms with straight line.This straight line portion that comprises terminal point is " comprising the second Kaifeng line terminal point at interior terminal part ", and as long as such terminal part is at least apart from terminal point 1mm or more than the 1mm, preferably 5mm or more than the 5mm.

In addition, the surface that is preferably in the flexible packing material that covers with cover is provided with the embrittlement portion that forms through the embrittlement processed.According to this mode,, can substantially reduce the rigidity of film by being located at the lip-deep embrittlement of flexible packing material portion.Therefore, when having peeled off cover, it is bonding easily that film is followed cover one side, so can induce means positively separated along tearing, peristome can be set positively.It is in addition, so-called that to form " embrittlement portion " through the embrittlement processed can be for example by the Kaifeng line towards sword processing or laser beam machining wire that form, as continuous lines or intermittent line.In addition, being not limited to the line that breaks a seal, also can be that for example the fine scar shape on part or all the film surface that form, that be formed at the open area such as embossing processed by its surface attachment diamond chip is concavo-convex.

In addition, the beginning portion of peeling off of cover preferably with its beyond other covers partly compare, its bind strength is weak or do not have a gleyness.According to this mode, can control easily and peel off beginning portion and peel off cover easily.

According to the present invention, such easy-open package can be provided, released part by cover, or by peelling off flexible packing material from the Kaifeng line that is formed at packaging body, thereby can form difform peristome, so can be also used as the different container of peristome shaped position of outer packaging container.

The specific embodiment

Below, the example to embodiments of the present invention describes in conjunction with the accompanying drawings.In addition, in the explanation of following embodiment,, omit or simplify its explanation the identical Reference numeral of identical constitutive requirements mark.

[first embodiment]

The integral body of＜easy-open package constitutes 〉

Fig. 1, the 2nd, the figure of an example of the embodiment of expression easy-open package of the present invention, Fig. 1 is the block diagram of expression easy-open package summary, Fig. 2 is near the enlarged drawing the cover 200 among Fig. 1.

As shown in Figure 1, this packaging body 100 is pillow package bodies of using the film 110 made by flexible packing material to be constituted.Under state, be bonded with cover 200 in the upper surface side of film 110 with packaging body 100 horizontal positioned.The other end 131 of packaging body 100, an end 132 are respectively upper and lower across seal portions, and the central portion of side has not shown back side mouth-sealed portion overleaf.

As shown in Figure 2, on the film 110 of the part that cover 200 covers, be formed with the second Kaifeng line 220 towards the コ word shape of an end 132, from this second Kaifeng line 220 2 form the first Kaifeng line 210 with ring-type.That is, in the present embodiment, the second Kaifeng line 220 and first Kaifeng line 210 a part of conllinear, its result, the first Kaifeng line 210 becomes ring-type.Kaifeng line 210 by this ring-type forms open area 150.In addition, so-called " open area " is meant film by the zone before being peelled off, and so-called " peristome " is meant the zone that film reality has been peelled off.

Cover 200 can be separated into 200a, 200b by cut-off rule 230, and this 200a, 200b have second respectively and peel off the 240a of beginning portion, first and peel off the 240b of beginning portion, and are adhered on the film 110.In order to peel off cover 200 easily, preferably to peel off beginning portion and compare with other parts except that it, its bind strength is low or do not have a gleyness.At this, so-called " bonding " is meant and can peels off and leak free state more again.

On the extended line of two terminal points of the second Kaifeng line 220 of the upper surface of film 110, be provided with: means 160 are induced in two parallel tearing that are extended to across seal portion 132 (end of packaging body) from here.In the present embodiment, tearing and inducing means 160 is to be recited as long and two-short dash line, and in fact, the draw direction of the oriented film of formation film 110 is consistent with long and two-short dash line, and the orientation of this oriented film becomes the means 160 of inducing of tearing.

＜film 〉

Though film 110 is unqualified to be specific material,, the material that preferably can obtain bag shape and have the moisture resistance that is used to prevent inner wet tissue drying by heating, film adhesion.In addition, can also use its material as monomer, have gleyness and bubble-tight material, also can use several materials that have the film of different qualities respectively bonding.

In addition, will film as uniaxial drawing PET film, that improved tearing property of one-way during as base film, when then forming peristome, can form peristome straight line, stable, so be best tearing film from the slit.

＜the first Kaifeng line and the open area 〉

The first Kaifeng line 210 is so long as get final product with the mode setting of the open area 150 that produces ring-type.In Fig. 2, though have the shape of semiellipse shape, can be quadrangle, circle also, be not particularly limited.In addition, the size that becomes the open area 150 of conveying end also can or be taken out the size of content or shape and suitably selecting according to the size of packaging body 100.

The first Kaifeng line 210 is from just having formed at first the state of open area 150, can be states as shown in Figure 1, film 110 covering open areas 150, also can remove the film 110 that covers open area 150 in advance.Film 110 covers under the situation of open area 150, can be to punch film 110 and the state of complete opening, nature disconnection degree, so-called intermittent line degree in the time of also can be with the strip off label, its part or a plurality of parts be connected in the state on the film 110 of packaging body.In addition, can as being called as half cut off, be not die-cut fully to the thickness direction of film yet, be not cut to the undermost state of film.In such cases, when peelling off cover 200b, be preferably in and be pre-formed the Kaifeng line on the film 110, so that form the open area easily.In a word, when peelling off cover 200, so long as formation just can corresponding to the state of the peristome of the packaging body of horizontal vessel peristome.

＜the second Kaifeng line 〉

As long as the second Kaifeng line 220 is arranged to and can be formed the open area continuously to across seal portion 132 from the second Kaifeng line 220, its shape does not have specific limited.In order to form continuously to across seal portion 132, the terminal point that preferably comprises the second Kaifeng line 220 in interior terminal part and angles angle, across seal portion 132 sides of line that are parallel to direction of delaminate less than 90 °.In the present embodiment, this second Kaifeng is after line 220 is formed in the mode perpendicular to the cover direction of delaminate, with direction of delaminate abreast towards across seal portion 132, its terminal part forms the L word shape.

The embrittlement portion 250 of V-shape also can be set in the end side of packaging body of the second Kaifeng line 220 in addition.By this embrittlement portion 250, can reduce the rigidity of film 110.Thus, film 110 is easily by warpage, so open stripping from the second Kaifeng line 220 easily.Make film 110 easily by warpage as long as embrittlement portion 250 forms, its shape, length, bar number can suitably be set.For example, embrittlement portion 250 can be zig-zag, corrugated, R shape, also can be difform combination.In addition, can have only one, also can not be continuous lines but intermittent line.

In addition, the Kaifeng line can form the state that connects film 110, also can be the state of so-called half cut off, but the departure point of easier warpage is considered from reducing the film rigidity, preferably forms and connects film 110.In addition, half cut off can be by for example forming with the irradiation of laser or mechanical known method towards sword processing etc.

As mentioned above, the Kaifeng of second in present embodiment line 220 is and the first Kaifeng line 210 part conllinear.Its end forms from 2 ends towards packaging body of the first Kaifeng line 210.The second Kaifeng line is so long as be arranged to arrive across seal portion 132 and get final product the formation open areas continuously, and its shape is コ word shape or Eight characters shape preferably.In order to form peristomes continuously to across seal portion 132, the terminal point that preferably comprises the second Kaifeng line 220 in angles angle, across seal portion 132 sides of interior terminal part and the line that is parallel to direction of delaminate less than 90 °.

In order to make the directivity of tearing film stable as far as possible, preferably the second Kaifeng line 220 is cut fully and is worn film.Under the situation that is intermittent line, during with part that film 110 links to each other, rift direction can be disorderly, can not tear to want direction at tear fracture.Under the situation of half cut off, because the part of the residual orlop film that is not cut open also, so, make the direction disorder of breaking equally, can not tear to want direction, the film that the film on upper strata of " layering " and lower floor may occur being called as begins to peel off and can not stablize the formation peristome in the portion of breaking, and is therefore undesirable.
