Description
SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a packaging body and resin-made film used therefor that can store the remaining contents even after a part of the contents is taken out, wherein the packaging body is easily openable and closable without providing a zipper, has a storage property equal to that of a body provided with a zipper, and can be manufactured at a low cost.
Namely, the present invention is a packaging body which houses contents in a sealable manner and at least a part of which is constructed with a resin-made film, where an opening part is formed in the resin-made film for taking the contents out, characterized in that; the resin-made film is constructed with at least an outer layer, an inner layer, and an adhesive layer in the middle thereof formed by applying an adhesive onto the outer layer and/or the inner layer; the adhesive is releasable and re-adherable; and at least a part of the adhesive layer is formed by a combination of an adhesive part where said adhesive is continuously applied and a part where said adhesive is discontinuously applied or a part where the adhesive is not applied (these are referred to as �non-adhesive part�),
A resin-made film for a packaging body according to the present invention is characterized in that the resin-made film is constructed with at least an outer layer, an inner layer, and an adhesive layer in the middle thereof formed by applying an adhesive onto the outer layer and/or the inner layer; the adhesive is releasable and re-adherable; and at least a part of the adhesive layer is formed by a combination of an adhesive part where said adhesive is continuously applied and a part where said adhesive is discontinuously applied or a part where the adhesive is not applied (these are referred to as �non-adhesive part�).
In the packaging body such as described above according to the present invention, functions of easily taking out the contents by opening of the opening part, re-closing of the opening part by covering the opening part, and being capable of repeating this are required. As already described, it is difficult to realize these functions with a simple combination of materials of the resin-made film for packaging bodies and adhesives such as in the prior art. As a result of verification, it has been made possible to realize these functions by constructing a resin-made film made of at least an outer layer, an inner layer, and an adhesive layer, and constructing the adhesive layer with a combination of an adhesive part where the adhesive is continuously applied and a non-adhesive part where the adhesive is discontinuously applied and/or the adhesive is not applied. Namely, for the contradicting functions of the adhesive layer of �facilitating the peeling off� and �ensuring the re-adhesion strength�, it has been made possible to set optimum conditions by not only selecting the adhesive but also selecting the pattern of application of the adhesive, the combination of the non-applied parts, and the amount of application thereof. Therefore, it has been made possible to provide a resin-made film used for a packaging body which is easily openable and closable, which nevertheless has a high sealing property, and which can be produced at a low cost. As the resin-made film for a packaging body according to the present invention, in addition to those produced by resin alone such as a later-described OPP (biaxially stretched polypropylene) film or a PET (polyethylene terephthalate) film, a film having aluminum vapor-deposited on the front surface thereof and a film having aluminum foil or the like laminated thereon are included.
The non-adhesive part is an important construction for ensuring the functions of �peeling off and re-adhesion of the outer layer�. Here, in order to prevent decrease in the peeling function due to excessively large adherability and decrease in the re-adhering function due to excessively small adherability, the amount of application of the adhesive onto the resin-made film and the pattern as well as the verification of the characteristics of the adhesive itself will be important factors. In the present invention, as a result of verification of these, as one effective method, it has been found out that the above-described two functions can be ensured by forming a pattern on which the adhesive is applied discontinuously in a straight line form or in a curved line form, whereby a secure sealing property can be ensured after the re-adhesion with little load imposed upon the user.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory drawing for illustrating one of the fundamental construction of the packaging body according to the present invention;
DETAILED DESCRIPTION OF THE INVENTION Embodiments of the packaging body according to the present invention will be described in detail with reference to the drawings. The packaging body houses contents in a sealable manner, and at least a part thereof is constructed with a resin-made film, and an opening part for taking out the contents is formed in the resin-made film. As specific modes, a packaging body fabricated by superposing resin-made films onto each other and sealing the end parts, a packaging body fabricated by joining a container having an opening and having a predetermined shape with a resin-made film forming the top seal thereof, and others are possible.
The resin-made film used in the packaging body P is constructed with at least an outer layer, an inner layer, and an adhesive layer in the middle thereof formed by applying an adhesive onto the outer layer and/or the inner layer; the adhesive is peelable and re-adherable; and at least a part of the adhesive layer is formed by a combination of an adhesive part where the adhesive is continuously applied and a part where the adhesive is discontinuously applied or a part where the adhesive is not applied (these are referred to as �non-adhesive parts�). Regarding the number of laminations of the resin-made film, a case of two layers will be hereafter touched upon for the sake of the simplicity of description; however, it goes without saying that the number and the kind (materials and processes) of the layers can be changed in accordance with the usage thereof, and there may be cases in which they are changed.
Specifically, as shown in FIG. 2(A), the resin-made film is formed by lamination of an OPP film or a PET film (corresponding to �an outer layer�, referred to as an outer layer 5) having a thickness of about 10 to 50 μm and an LLDPE (linear low density polyethylene) film (corresponding to �an inner layer�, referred to as an inner layer 6) having a thickness of about 30 to 50 μm. On the back surface side of the outer layer 5 (the side opposing the inner layer 6) or the front surface side of the inner layer 6 (the side opposing the outer layer 5), by printing or the like an adhesive layer 8 that the adhesive is applied at necessary sites as a pattern is formed. Also, in the resin-made film, an opening part 10 a for taking the contents M out is provided when the packaging body is fabricated. Specifically, as exemplified in FIG. 2(B), a structure is preferable in which a breakable slit 10 a (corresponding to the opening 10 a) is provided in the inner layer 6 so that the packaging body can be opened when the outer layer 5 is peeled, and the packaging body can be tightly closed when the outer layer 5 is re-adhered. In a step of fabricating the resin-made film, one smooth process can be constructed by applying an adhesive on the outer layer 5 and attaining a semi-dried state with use of a dryer, forming a slit in the inner layer 6, and bonding the inner layer 6 and the outer layer 5 in a state in which creases are extended. Specifically, the present step can be constructed, for example, at about 140 to 150 m/min to fabricate the resin-made film.
Generally in the formation of the adhesive layer 8 applying the adhesive, the adhesive is applied wholly on the surface. But adhesion and peeling-off of the outer layer 5 of the packaging body P in the present invention are carried repeatedly, so it is preferable that the adhesive layer 8 may formed with not only a part applied the adhesive (adhesive parts 8 b) but also non-adhesive parts 8A to 8E (these are referred to as �non-adhesive parts 8 a�) forming the combination of adhesive parts exemplified in FIG. 3(A) to 3(E) and a part 8 n not applied the adhesive. According to a condition of the size of resin-made film and opening part forming the packaging body P or of the use temperature and the condition of the contents M, the peeling-off and re-adhesion of the outer layer 5 is easy by controlling a material and thickness of the resin film, a kind of the adhesive, a width and height of the adhesive forming non-adhesive parts 8 a, or a ratio of the adhesive area per unit area. Then this pattern can be easily made by dry chisel. And the change of the pattern can be comparatively easy, so the voluntary combination of the patterns can be easy. Specifically, FIG. 3(A) shows the pattern 8A of non-adhesive parts 8 a applied the adhesive fragmentarily in the straight or curved shape. The strength of adhesion and peeling-off is controlled by the ratio of non-adhesive parts 8 a and adhesive parts 8 b and the direction of adhesive parts 8 b. FIG. 3(B) shows the pattern 8B of non-adhesive parts 8 a applied the adhesive continually with form of spline. It has the same function as that of the pattern applied the adhesive fragmentarily above described, and can get the higher strength. FIG. 3(C) shows a pattern 8C of the non-adhesive parts 8 a on which an adhesive is applied in a straight line shape and in a wave-like manner. By simply changing the width of the adhesive parts 8 a, the adhesion/peeling off strength can be adjusted. FIG. 3(D) shows a pattern 8D of the non-adhesive parts 8 a on which the adhesive is applied in a lattice form. By enhancing the adhesion strength relative to the longitudinal direction in addition to the functions of the pattern 8C in the lateral direction relative to the front of the view, the adhesion/peeling off strength having no orientation can be adjusted. Also, by setting the inter-lattice distance or the thickness of the lattice in an arbitrary manner, the adhesion/peeling off strength can be adjusted with a further better precision. FIG. 3(E) shows a pattern 8E of the non-adhesive parts 8 a on which the adhesive parts 8 b in a lattice form and the part 8 n where the adhesive is not applied are alternately formed. While giving priority to the adhesion strength relative to the lateral direction, an intermediate function of the patterns 8C and 8D can be obtained. By setting the inter-lattice distance or the thickness of the lattice in an arbitrary manner, the adhesion/peeling off strength can be adjusted with a further better precision.
