Description

  The present invention is a hermetically sealed package that allows smooth removal of a stack of filter paper sheets, which are the items to be packaged inside, one by one from the top layer, and allows easy resealing to the opening of the lid. It is about the body.

  Conventionally, filter paper used for coffee drip is laminated with tens to hundreds of tens of sheets as one unit, and a paper bundle of a plurality of the laminated filter papers is wrapped in a paper box or film It is marketed by packaging in a bag.

  However, conventional film packaging bags cannot be sealed once they are opened when filter paper is used, and more than one filter paper cannot be used up at a time. Fold the periphery of the opening formed and fix the film packaging bag with rubber bands in this folded state, or use a commercially available adhesive tape to seal the opening formed It was necessary to take measures such as

  In addition, when a paper box is used, or when a film packaging bag is opened or left for a long period of time with a low sealing property such as rubber band fixation, the presence in the air There are problems that odor components, dust, and other various substances adhere to the filter paper. When the filter paper to which the above components are adhered after being left for such a long time is used for a coffee drip, there is a risk of adversely affecting the aroma and taste of the coffee to be drip.

  In addition, when sealing the opening using a commercially available adhesive tape, the adhesive component of the adhesive tape adheres to the packaging bag side by removing the adhesive tape when using filter paper, and this adhering matter takes out the filter. There is also a risk of sticking to paper. Moreover, when the adhesive component of an adhesive tape adheres to the packaging bag side in this way, there exists a complexity which must prepare a new adhesive tape.

  As a technique related to the opening to the packaging body as described above, the stacked cooking sheets are stored in the box body, and the takeout port straddling between the upper surface portion and the one side surface portion of the box body, There has been disclosed a cooking sheet packaging body provided with an opening line that leaves the lower part and both side parts of the side surface part and the rear part and both side parts of the upper surface part (see, for example, Patent Document 1). In the package of Patent Document 1, the box is cut along the opening line, and the takeout opening is opened by folding the cut inner part upward along the folding line. Moreover, the cut | disconnected inner part functions as a cover part, and prevents the penetration | invasion of the foreign material after opening.

  In addition, the pillow package has a top end portion and a bottom end portion that are laterally sealed and has a palm portion in the vertical direction, and has means for cutting the palm portion in at least one side end region of the palm portion. In addition, the region having the cutting means is in close contact with the surface of the pillow package body, and is the side end region of the pillow package on the side opposite to the side end portion of the palm portion, which is substantially the same as the cutting means. A pillow package having a means for opening the pillow package in a parallel position is disclosed (for example, see Patent Document 2). In the package shown by this patent document 2, the recloseability is provided to the package by attaching a zipper to the inner surface of the package.

  Moreover, the pillow type | mold which has a pair of horizontal seal part which each seals the upper end part and lower end part of the cylindrical body in which the opposing end parts of the film overlapped and stuck in the shape of a belt | band | zone, and the vertical seal part was formed, respectively. A predetermined opening start structure is formed at a position near one horizontal seal portion of the vertical seal portions, and the opening start structure is formed by two cuts formed adjacent to each other. The portion between the two cuts in the vertical seal portion is not adhered, and the packaging bag is opened along the horizontal direction starting from the opening start structure, so that one of the packaging bags is opened from the opening location. A packaging bag in which a portion on the side of the lateral seal portion can be used as a lid of an opened packaging bag, and the lid can be bound by a strip of the packaging bag generated by opening along the lateral direction. Disclosed (for example, See Patent Document 3.). In the packaging bag shown in this patent document 3, it can be opened by opening the notch part in the left and right direction, the upper side seal part side becomes a lid by this opening, and the lower side seal part side part is the main body. Part. And when closing the lid | cover of the packaging bag after opening, after covering a main body part, the lower end of a lid | cover is tied by the string part produced by opening.

  In addition, a packaging bag formed of a soft laminated sheet for hermetically sealing the contents, a hard shape-retaining sheet fixed to the outer surface, and a pressure-sensitive adhesive layer surface that can be re-removed and re-adhered to the shape-retaining sheet are applied. A cover body having a lid label bonded to and in contact with the laminated sheet and the shape-retaining sheet in a region where the lid label is bonded, so that the cut line is closed. A packaging body is disclosed that can be peeled off from a part of the shape-retaining sheet excluding the planned opening part surrounded by the cut line and can be opened and closed so that the peeled part can be reattached. (For example, refer to Patent Document 4). According to the package of the above-mentioned patent document 4, it can be peeled from the shape-retaining sheet from one end side of the lid label, and only the part surrounded by the cut line formed in the laminated sheet and the shape-retaining sheet is cut off. Since the opening is formed in the portion surrounded by the cut line of the laminated sheet and the shape-retaining sheet while being adhered to the lid label, the packaging object can be easily taken out from the opening. .

JP-A-10-17024 (Claim 1, paragraphs [0011] and [0016], FIGS. 1 to 3) Japanese Patent Laying-Open No. 2006-69663 (Claims 1 and 5, paragraphs [0029] and [0057], FIGS. 1 and 2) JP 2008-290723 A (Claim 1, paragraphs [0021] to [0024], FIGS. 6, 9, and 10) JP 2009-249032 A (Claim 1, paragraph [0007], FIGS. 1 and 3)

  However, the package shown in Patent Document 1 is a box that uses a material that easily maintains its shape, such as cardboard, cardboard, or a composite material in which a synthetic resin film is laminated on paper. Since the shape of the take-out port provided in is complicated, there is a problem that the manufacturing cost increases. In addition, although the open outlet is closed by the lid, the degree of sealing is not sufficient, and when filter paper is used as the contents, various substances such as odor components may adhere to the filter paper. is there. In addition, when a soft film or the like is used as the material, the lid for closing the opened outlet is also soft, so the sealing degree is lower and foreign matter can be prevented from entering inside. As a result, the material used is limited.

  Moreover, in the package shown by the said patent document 2, since the zipper is mounted | worn with the package inner surface, although a sealing degree becomes high, there exists a problem that manufacturing cost also becomes high correspondingly. In addition, there is no problem when the contents are solids such as foods or corn flakes, but the vertical and horizontal dimensions are different from those of coffee filter paper, and the shape is large and easy to tear. When the contents are used as the contents, the filter paper end may be caught by the zipper and damaged when taken out from the package.

  Moreover, in the packaging bag shown by the said patent document 3, after opening, since an opening part cannot be sealed, it is inferior to airtightness, and also binds with the strip | belt piece (string part) of the packaging bag produced by opening Since the lid is closed by this, the shape of the package at the tied-up position is crushed, which is not suitable for packaging contents that need to be maintained in the shape of coffee filter paper.

  Furthermore, in the package shown in the above-mentioned Patent Document 4, as shown in FIGS. 1 and 3 of Patent Document 4, the opening formed by peeling off the lid label is the central portion of the surface of the package and in the vertical direction. If the contents are wet tissue, candy, chocolate, etc., there is no problem, but the vertical and horizontal dimensions are different and the shape is large, such as coffee filter paper. In the case of using as a content, there is a problem that it is difficult to take out from the package. Moreover, since it is necessary to laminate | stack a shape retention sheet between a packaging bag and a lid | cover label, manufacturing cost rises.

  The object of the present invention is to smoothly perform the operation of taking out a sheet bundle of laminated filter papers, which are to be packaged inside, one by one from the top layer, and to the opening of the lid material. An object of the present invention is to provide a sealed package that can be easily resealed.

  As shown in FIG. 3, the first aspect of the present invention is as shown in FIG. 1, with a palm portion 2 in which end portions facing each other of a rectangular soft synthetic resin film having airtightness overlap each other in a band shape and are in close contact with each other. The upper end seal portion 3 that seals the upper end portion of the cylindrical body formed by being closely attached to the palm portion, and the lower end seal portion 4 that seals the lower end portion of the cylindrical body, and has a palm portion. A package body 1 having an opening 5 on the upper surface opposite to the side, and a lid that covers the opening 5 and is adhered to the surface of the package body 1 at the periphery of the opening 5 so as to be removable and reattachable. In the sealed package 10 which is composed of the material 6 and in which the package 7 is packaged, the package 7 has two arcuately trapezoidal filter papers each having an arcuate upper edge. The left and right edges and the bottom edge are joined together to separate the arc-shaped free edges from each other. And a paper bundle in which a plurality of filter papers used for coffee drip configured to form an inverted frustoconical bag are stacked, and the opening 5 is provided horizontally in the upper half of the package body 1. It is characterized by that.

  The second aspect of the present invention is based on the first aspect, and further, as shown in FIG. 2, the length of the opening 5 in the longitudinal direction is smaller than the length of the filter paper 7 in the short direction. 110% to 70%.

  A third aspect of the present invention is a device based on the first aspect, characterized in that the opening 5 is positioned so as to cross the lateral direction of the filter paper 7 as shown in FIG. To do.

  The fourth aspect of the present invention is based on the first aspect, and as shown in FIG. 2, the filter paper 7 has a convex knob 7a at its upper edge, and the opening 5 has a knob. It is provided in the position which faces the part 7a.

  In the first aspect of the present invention, since the opening portion is provided horizontally in the upper half of the package body, a sheet bundle of laminated filter papers, which are the packages to be packaged inside, is one sheet from the top layer. The operation of taking out each item can be performed smoothly. In addition, since the lid is adhered to the surface of the package body at the periphery of the opening so as to cover the opening, the lid can be easily re-sealed to the opening. The hermetic sealability of the package is improved.

  In the second aspect of the present invention, since the length of the opening in the longitudinal direction is 110% to 70% with respect to the length in the short direction of the filter paper, the length of the opening in the longitudinal direction is too short. When the filter paper is taken out from the opening, the package body and the filter paper are not damaged due to catching or the like. Further, there is no inconvenience of sticking the lid material so as to go around to the side surface side of the package when the lid material is resealed due to the length of the opening in the longitudinal direction being too long. Furthermore, if the length of the opening in the longitudinal direction is too long and reaches the side of the package or the vicinity thereof, the shape of the package is likely to collapse, but the longitudinal direction of the opening is provided only on the surface of the package. Therefore, the shape retention of the package is also excellent.

  In the third aspect of the present invention, since the opening is positioned so as to cross the transverse direction of the filter paper, the object to be packaged serves as a flat base. When the part is re-adhered, the lid becomes easy to stick, and the package body is less likely to wrinkle.

  In the 4th viewpoint of this invention, since the opening part was provided in the position which faces the knob | pick part of filter paper, when taking out filter paper, since it became possible to pick and pull out a knob | pick part, The operation to take out the filter paper becomes smoother.

It is the perspective view which represented typically the sealing packaging body surface side which concerns on this invention. It is a perspective view which shows the open state of the sealed package body of FIG. It is the perspective view which represented typically the sealed package body back side of this invention.

  Next, embodiments for carrying out the present invention will be described with reference to the drawings.

  As shown in FIG. 1, a hermetically sealed package 10 according to the present invention includes a package body 1 and a lid member 6, and an article to be packaged 7 is packaged therein. The packaged object 7 has an arcuate upper edge and two substantially trapezoidal filter papers, and the left and right edges and the lower edge are joined together to separate the arcuate free edges from each other. A paper bundle in which a plurality of filter papers used for a coffee drip configured to be an inverted frustoconical bag is laminated.

  A rectangular soft synthetic resin film having airtightness is used for the package body 1. This is because the soft synthetic resin film is excellent in handleability and processability and is economically preferable. The material of the soft synthetic resin film is a single film of a synthetic resin film such as polyethylene, polypropylene, ethylene-vinyl alcohol copolymer, polyester, polyamide, vinyl chloride, vinylidene chloride, cellophane, acetate, or a laminate of two or more of these. A film, a laminated film obtained by depositing aluminum on a single film or a laminated film, a laminated film obtained by laminating a resin film on a metal foil such as aluminum, or the like can be used. These laminated films can be produced by appropriately using a known lamination method such as a sandwich lamination method, a dry lamination method, or a melt extrusion lamination. The thickness of the film used is 10 to 300 μm, and 20 to 150 μm is preferable among them. When the thickness is less than the lower limit, the airtightness is poor and the film is easily broken. When the thickness exceeds the upper limit value, it becomes difficult to manufacture and process, and the material is used more than necessary, leading to an increase in manufacturing cost.

  A cylindrical body is formed by overlapping and adhering opposite ends of the soft synthetic resin film in a band shape. The close contact portion is a palm portion 2 as shown in FIG. Returning to FIG. 1, the upper end seal portion 3 and the lower end seal portion 4 are formed by sealing the upper end portion and the lower end portion of the cylindrical body, respectively. Furthermore, an opening 5 is provided on the upper surface on the side opposite to the side where the palm portion 2 is formed. In this way, the package body 1 is configured.

  The lid member 6 covers the opening 5 and has an area capable of adhering to the surface of the package body 1 at the periphery of the opening 5. The material of the lid member 6 is not particularly limited. Moreover, it is preferable to have the knob | pick part 6a in the end of the longitudinal direction of the cover material 6, and the notch part 6b in the other end. By having the knob portion 6a, the lid member 6 can be easily picked with a fingertip, so that the act of attaching or peeling the lid member 6 is facilitated. In addition, as shown in FIG. 2, when the lid member 6 is opened, the cut portion 6 b serves as a stopper, so that the lid member 6 is not peeled off excessively, and the lid member 6 is completely peeled off from the package body 1. This can be prevented.

A re-peelable pressure-sensitive adhesive capable of re-peeling and re-adhering is applied to the back side of the lid member 6, that is, the side in close contact with the package body 1. As the pressure-sensitive adhesive provided on the back surface of the lid member 6, a pressure-sensitive adhesive that can be removed and re-adhered is used. The re-peeling pressure-sensitive adhesive has a feature that it can be peeled off again after being attached and can be re-adhered after peeling. By increasing the cohesive force of the whole pressure-sensitive adhesive while leaving the pressure-sensitive adhesive force, it can be applied and peeled off many times. As the re-peelable pressure-sensitive adhesive, either a solvent-type pressure-sensitive adhesive or an emulsion-type pressure-sensitive adhesive may be used. As the solvent-type pressure-sensitive adhesive, rubber-based or acrylic resin-based is used. As the emulsion (or latex) type adhesive, natural rubber latex, synthetic rubber latex, acrylic resin emulsion or the like is used. A resin pressure-sensitive adhesive in which a tackifier such as a terpene resin or rosin is blended with a rubber-based resin or a synthetic resin can also be used. The re-peelable pressure-sensitive adhesive can be applied to the lid member 6 by a known application method such as a gravure coating method, a roll coating method, or a heat-melt extrusion method. Moreover, you may add additives, such as a thickener, a dispersing agent, an antifoamer, an antistatic agent, and antiseptic | preservative, to a re-peeling type adhesive as needed. The amount of the re-peelable pressure-sensitive adhesive applied to the lid material is preferably 5 to 80 g / m ^{2, and} more preferably 10 to 40 g / m ^{2 in} terms of solid content. In addition, the application of the re-peelable pressure-sensitive adhesive to the lid member 6 does not damage the package 7 and is economical if it is applied only to the portion to be attached to the surface of the package body 1 at the periphery of the opening 5. This is preferable.

  The characteristic configuration of the present invention is that the opening 5 is provided horizontally in the upper half of the package body 1. Since the opening 5 is provided horizontally in the upper half of the package body 1, the operation of taking out the sheet bundle of the laminated filter paper, which is the packaged object 7 packaged inside, one by one from the uppermost layer smoothly It can be carried out. Further, the lid 6 is adhered to the surface of the package body 1 around the opening 5 so as to cover the opening 5 so as to be removable and re-adhesive, so that the lid 6 is resealed to the opening 5. Is easy, and the hermetic holding property of the package 7 is improved.

  Further, it is preferable that the length of the opening 5 in the longitudinal direction is 110% to 70% with respect to the length of the filter paper 7 in the short direction. Due to the fact that the length in the longitudinal direction of the opening 5 is too short relative to the length in the short direction of the filter paper 7 by 110% to 70%, the length in the longitudinal direction of the opening 5 is too short. When removing the filter paper 7 from the opening 5, the package body 1 and the filter paper 7 are not damaged due to catching or the like. Further, when the lid 6 is resealed due to the length of the opening 5 in the longitudinal direction being too long, bothering to attach the lid 6 so as to go around to the side surface side of the package body 1 is troublesome. There is not. Furthermore, if the length of the opening 5 is too long and extends to the side surface of the package body 1 or the vicinity thereof, the shape of the sealed package 10 tends to collapse. Since it is provided only on the surface of the body body 1, it is excellent in the shape retention of the package.

  The opening 5 is preferably located so as to cross the short direction of the filter paper 7. By positioning the opening 5 so as to cross the lateral direction of the filter paper 7, the article 7 to be packaged inside serves as a flat base. When sticking, the lid 6 is easy to stick, and the package body 1 is less likely to be wrinkled.

  Furthermore, it is preferable that the filter paper 7 is provided with a convex knob 7a at the upper end edge, and the opening 5 is provided at a position facing the knob 7a. By providing the opening 5 at a position facing the knob 7 a of the filter paper 7, the filter paper 7 can be pulled out by pulling the knob 7 a when the filter paper 7 is taken out. The operation to take out becomes smoother.

  A method for producing the sealed package of the present invention will be described. A generally available pillow wrapping machine can be used for manufacturing the sealed package of the present invention. The pillow wrapping machine can be used either vertically or horizontally.

  First, a rectangular soft synthetic resin film having airtightness is continuously supplied. Then, an opening is formed in the supplied soft synthetic resin film for removing a hole by extracting a hole using a mold or the like. When the package is formed, the opening is formed on the upper surface of the package body so as to be horizontally long in the upper half. On the other hand, a lid member having an area capable of covering the opening is prepared, and a releasable adhesive is applied to the back side of the lid member. Next, a lid material coated with a releasable adhesive on the back side is supplied and placed on the surface on which the opening portion of the soft synthetic resin film is formed, and the peripheral portion of the lid material and the peripheral portion of the opening portion The mutual abutting portions are adhesively bonded. Next, prepare a paper bundle of filter paper laminated as a predetermined number of items to be packaged, wrap the paper bundle with a soft synthetic resin film that is adhesively bonded to the lid material, and connect the opposite ends of the resin film to each other. A palm portion is formed by overlapping and adhering in a band shape. Next, the end overlapping portions formed on both ends of the palm portion are joined to form a bag. Further, by cutting the boundary portion between the bag bodies and individually separating the bag bodies, a sealed package body in which an article to be packaged is packaged is manufactured.

  Thus, the sealed package of this invention can be obtained by passing through the said process. In the above method, since the sealed packaging body of the present invention can be manufactured only by partially improving the existing production equipment for manufacturing the conventional packaging body, it can be manufactured relatively easily. There are effects such as a small cost increase from the manufacturing cost of the body.

  The hermetically sealed package of the present invention is not limited to filter paper configured to be an inverted frustoconical bag, and may be used for packaging filter paper configured to be an inverted conical bag.
