Description

  The present invention relates to a package that is externally fitted to an object to be packaged such as a container in which the stored items are stored.

  Conventionally, as a package of a packaged object such as a container in consideration of display properties at the time of display, an annular package of a predetermined width with a decoration such as a pattern is externally fitted to the packaged object, and the opening of the package Some of them have a device to increase the purchase motivation of the purchaser so that the packaged items can be seen from the part.

In addition, in order for this type of package to stably fit and hold the packaged object, slits are provided at both side corners of the upper part of the package, and the flange (flange part) provided in the packaged object such as a container in the slit. ) Are fitted and held externally, and those provided with a clamping means for clamping a collar part provided in the packaged object on the upper part of the package (for example, see Patent Document 1).
JP-A-10-236523

  However, since the packaged object that does not include the collar portion is difficult to be stabilized in the conventional package, there is a concern that the packaged product may fall out of the package.

  Moreover, the packaging body which fits the collar part which a to-be-packaged article is fitted to the slit provided in the both-sides corner part of a packaging body equips the upper part after connecting the both ends of a strip | belt-shaped sheet | seat, and forming an annular | circular shape in the upper part. Even when trying to insert a packaged object, the upper part width of the packaged object is larger than the opening width of the upper part of the package by the amount of the collar part, so that there is a problem that the collar part is caught and difficult to insert.

  On the other hand, an annular package body made of a heat-shrinkable film that is externally fitted to an object to be packaged by being thermally contracted as a whole has also been provided. However, since such a package shrinks as a whole along the shape of the package when it heat shrinks, the shrinkage rate at each part of the package becomes uneven, and patterns and characters attached to the package However, there was a problem that it was distorted when contracted.

  Therefore, the present invention can easily insert a packaged object even after being formed into an annular shape, and can stably fit and hold even a packaged object that does not have a collar part. It is an object of the present invention to provide a package that does not impair decorative effects such as printed patterns.

  In order to solve the above-mentioned problems, the packaging body according to the present invention has an annular shape by connecting both end portions of a belt-like sheet, and is at least one place on the peripheral surface of the packaging body that is externally fitted to an article to be packaged such as a container. And a contraction part capable of reducing the length in the circumferential direction by thermal contraction.

  By adopting the above configuration, the package is formed in an annular shape by connecting both end portions of the belt-shaped sheet, and the package is inserted through the opening formed at that time, and then the heat is applied to the contraction portion. In addition, by heat shrinking, the overall length is shortened, the opening diameter of the annular package is shrunk, and even a container that does not have a collar portion is stably fitted and held.

  In addition, the contraction portion may be configured to include a contraction body that is fixed to the sheet at at least two locations that are separated from each other in the circumferential direction and that can contract the sheet between the fixing portions by thermal contraction. With such a configuration, if heat is applied to the heat-shrinkable body, the sheet is contracted and the sheet between the fixed portions is contracted, whereby the overall length is shortened and the opening diameter of the annular package is contracted and inserted. It becomes possible to externally hold the packaged item.

  Further, the sheet between the fixed portions may be configured to have an opening. By setting it as such a structure, since the area of the sheet | seat of the position facing a contraction effect | action body becomes small, the elastic resistance of the sheet | seat with respect to contraction of a contraction effect | action body decreases, and a contraction part becomes easy to contract. As a result, the opening diameter of the annular package body is easily reduced, and the inserted article to be inserted can be held tightly.

  Further, the sheet between the fixed portions may have a plurality of bent portions in the width direction and be formed to be bent in a bellows shape. Even with such a configuration, when the contraction acting body contracts in the circumferential direction, the sheet of the facing portion becomes bellows-like, so that the elastic resistance of the sheet against the contraction of the contraction acting body is further reduced. As a result, the contracted portion is more easily contracted, and the packaged object container inserted in the same manner as described above can be fitted and held more firmly.

  In addition, the contraction portion may be configured to include a contraction acting body that is interposed at both end portions of the separated sheet and can contract between both end portions of the sheet by thermal contraction. By adopting such a configuration, when heat is applied to the contraction acting body, the contraction acting body contracts to narrow the interval between both ends of the sheet, and the opening diameter of the annular packaging body is contracted and stored. It becomes possible to externally hold the packaged item.

  Further, the contraction acting body may be composed of a heat-shrinkable film. By adopting such a configuration, even if the heat-shrinkable film is provided on the inner peripheral surface of the annular package, it is a very thin member, so it is substantially flush with the inner peripheral surface of the package, It becomes possible to insert the packaged article easily without being caught when it is inserted into the package.

  Moreover, it is good also as a structure comprised by a top wall, a bottom wall, and a pair of side wall, and the said shrinkage | contraction part being provided in at least one of the said pair of side wall. By adopting such a configuration, for example, in the case where the package is a container composed of a bottomed cylindrical container body portion and an outer lid that fits into the upper opening, when the contraction portion contracts Since the opening diameter of the annular package shrinks in the direction of pressing the outer lid of the container accommodated in the package against the container body, the container is removed while firmly pressing the outer lid against the container body. It becomes possible to hold the fitting.

  As described above, according to the packaging body according to the present invention, the container can be easily inserted even after being formed into an annular shape, and even if the container does not include the collar portion, the outer fit is stably retained. can do. In addition, since only a part is contracted and the other most part is not contracted, a decorative effect such as a given pattern can be sufficiently exhibited.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG.1 and FIG.2, the package 1 in this embodiment is formed in the cyclic | annular form (short cylinder shape) by connecting the edge parts of the strip | belt-shaped sheet | seat 2 of 1 sheet. The package 1 formed in an annular shape is used by being externally fitted to the container 20.

  The sheet 2 is made of paper and is made of cardboard (board) having an appropriate thickness and rigidity. As the cardboard, not only the paperboard is used alone, but also a paperboard in which a plastic film such as an aluminum foil, polypropylene (PP), or polyvinyl chloride (PVC) is laminated on the surface may be used. By using such laminated paperboard, performance such as water resistance and strength can be improved in addition to appearance such as surface gloss and smoothness.

  In order to enhance the buyer's willingness to purchase by adding decoration to the surface of the sheet 2, for example, by using various types of printing such as lithographic printing and screen printing and stamping dies, etc. Add decoration.

  Next, the packaging body 1 includes a top wall 3, a pair of side walls 4, 5, and a bottom wall 6. That is, the sheet 2 has a crease part a in which one side upper side wall 5a, the top wall 3, the other side wall 4, the bottom wall 6, the one side lower side wall 5b, and the overlapping part 7 are sequentially provided with folding ruled lines. , B, c, d. And the lower end back surface of the upper side wall 5a and the surface of the superposition part 7 are stuck. As a result, an annular (short cylindrical shape) packaging body 1 having a predetermined width in which both front and rear sides are opened is configured.

  A heat contraction C is formed on the side wall 4. The heat-shrinkable portion C includes an opening 8 provided in the sheet 2, a heat-shrinkable film (hereinafter simply referred to as “film”) 9, and sheet-shrinkable portions 10 and 10. If it demonstrates concretely, the horizontally long rectangular opening 8 will be provided in the upper part of the side wall 4, and the film 9 will be arrange | positioned so that this opening 8 may be straddled. Further, since the opening 8 is narrower than the width of the sheet 2, sheet contracting portions 10 are formed on the left and right sides (in the width direction of the sheet 2) by the remaining portions of the sheet 2.

  More specifically, the opening 8 is formed in a rectangular shape that is narrower than the sheet 2, and is provided at the center position in the width direction of the sheet 2. For this reason, the left and right sides of the opening 8 are formed so as to be parallel to both sides (side edges in the length direction) of the sheet 2 and the upper and lower sides are perpendicular to the both sides.

  The film 9 may have any shape as long as it is larger than the vertical width of the opening 8 (the length direction of the sheet 2), but the appearance is better because the opening 8 is closed when the lateral width is about the opening width. This is preferable because the contraction force is also increased. In the present embodiment, it is formed in a rectangular shape that is slightly larger than the opening 8.

  As the film 9, a stretched film such as polystyrene (PS) or polyethylene terephthalate (PET) is used. The stretched film 9 is disposed so that its stretch direction is along the length direction of the sheet 2 (the circumferential direction of the package). By disposing in this way, the contraction rate in the length direction of the sheet 2 is increased during thermal contraction.

  The film 9 is adhered to the sheet 2 so as to close the opening 8 on the wall surface of the side wall 4. In the present embodiment, the film 9 is disposed (attached) on the back surface of the sheet (inner peripheral surface of the packaging body 1), but is disposed on the surface of the sheet 2 (outer peripheral surface of the packaging body 1). Or may be provided on both sides.

  The said sticking position is a position which pinches | interposes the said opening 8 of the film 9 arrange | positioned so that the opening 8 may be plugged up. Therefore, there is no sticking portion between the sheet 2 and the film 9 at a position where the opening 8 is sandwiched in the width direction. More specifically, it is attached linearly in the width direction at a position sandwiching the opening 8 in the length direction. And this linear sticking part is formed in the position along the upper and lower sides of the opening 8.

  In addition, in this embodiment, although linearly sticking to the width direction, this linear shape does not need to be continuous and may be discontinuous. Moreover, the number of linear sticking parts does not need to be one, and a plurality may be sufficient. Furthermore, the sticking part may not be linear but may be planar.

  Moreover, in order to stick the film 9 to the side wall 4 (sheet | seat 2), the adhesive agent is used in this embodiment. As the adhesive to be used, a part of the film 9 may be dissolved and used as an adhesive in addition to a liquid or gel adhesive generally used for packaging materials. Furthermore, a sticking part may use a double-sided tape or the like instead of an adhesive.

  As described above, since the rectangular opening 8 is provided at the center position in the width direction of the sheet 2, the sheet contracting portions 10 and 10 are formed in a belt shape having the same width and parallel to each other. Yes.

  A plurality of broken lines e, e,... Are formed in the sheet contraction portions 10, 10 in the width direction. These broken lines e, e,... Are formed in parallel to each other and at equal intervals. Further, the polygonal lines e, e,... Are alternately formed on the front and back surfaces of the sheet contracting portions 10 and 10.

  These broken lines e, e,... Are provided so that the sheet contracting portions 10, 10 can be easily bent along the broken lines e, e,. By doing so, when the film 9 contracts in the length direction of the sheet 2, the sheet contracting portions 10 and 10 are bent at the folding lines e, e,. Become.

  In this embodiment, the broken lines e, e,... Are formed by providing a half cut, but may be formed by perforations, press lines, or the like.

  On the other hand, as shown in FIG. 3, the container 20 accommodated in the package 1 is detachably attached to a bottomed cylindrical container body 21 in which instant food such as instant noodles is accommodated and an upper portion of the container body 21. A partition lid 22 to be fitted, and an outer lid 23 that is detachably fitted to the container body 21 and covers and closes the partition lid 22.

  Next, a method of using the package 1 will be described. First, as shown in FIG. 2A, the overlapping portion 7 of the sheet 2 and the tip of the upper side wall 5a are adhered. By doing so, a pair of side walls 4, 5 are erected from the left and right ends of the bottom wall 6, and the top wall 3 is provided so as to be installed between the upper ends of the pair of side walls 4, 5. A housing part for the container 20 is formed. And the container 20 of the said structure is inserted in this accommodating part from the opening of the one side of the package 1 into the inside.

  At this time, the height (distance between the inner surfaces of the bottom wall 6 and the top wall 3) Lr on the side wall 5 side constituted by the upper side wall 5a and the lower side wall 5b of the package 1 is the height of the container 20. It is set equal to or slightly higher than (the distance from the bottom surface of the container body 21 to the top surface of the lid body 23). On the other hand, the height Ll on the side wall 4 side is set to be higher than the height of the container 20. That is, the length of the side wall 4 is set longer than the length of the side wall 5.

  The width (interval between the fold portion a and the fold portion b) Wt of the top wall 3 of the package 1 is set equal to or slightly wider than the maximum diameter of the outer lid 23 of the container 20. Further, the width (interval between the crease part c and the crease part d) Wb in the left-right direction of the bottom wall 6 of the package 1 is set to be equal to or slightly wider than the bottom part diameter of the container body 21 of the container 20.

  Then, as shown in FIG. 5B, when heat is applied to the film 9 provided on the upper side of the side wall 4, the film 9 is thermally contracted to shorten the length of the side wall 4, and the side wall 4 of the package 1. The height Ll on the side becomes a height Ll ′ substantially equal to the height of the container 20. That is, when the length of the side wall 4 in the vertical direction is shortened, the space between the top wall 3 and the bottom wall 6 on the side of the side wall 4 of the package 1 is reduced, and the opening diameter of the annular package 1 is reduced. Therefore, the container 20 to be accommodated is externally fitted while force is applied from the packaging body 1 in the direction in which the outer lid 23 is pressed against the container body 21.

  At this time, as shown in FIG. 4, the film 9 provided on the upper portion of the side wall 4 is shrunk, but only the upper and lower sides are linearly attached to the sheet 2 in the width direction so as to sandwich the opening 8. As the film 9 shrinks, the sheet 2 (side wall 4) shrinks in the length direction (circumferential direction). Moreover, the part located in the left and right of the opening 8 in the film 9 is not stuck to the sheet 2. Therefore, the contraction of the film 9 in the length direction is not hindered by the sheet contraction portions 10 and 10.

  Further, the sheet contracting portions 10 and 10 are provided with folding lines e, e,... Alternately on the front and back surfaces so as to be easily bent alternately in the front and back directions. Therefore, the sheet bending portions 10 are alternately bent along the fold lines e, e,... To have a bellows shape, so that the contraction in the length direction of the film 9 is not hindered.

  Furthermore, although the film 9 is disposed (attached) on the back surface of the sheet (inner peripheral surface of the package 1), since the opening 8 is provided and exposed to the outside (front side), heat is applied from the outside. It is easy to add, and the film 9 can be thermally contracted more reliably and sufficiently.

  As described above, since the opening diameter of the packaging body 1 is larger than the outer periphery in the vertical direction of the container 20, the container 20 can be easily inserted into the packaging body 1 in which the sheet 2 is annular. Then, by applying heat to the film 9 and sufficiently shrinking it, the package 1 can be stably fitted and held even in the case of the container 20 that does not have a collar. At this time, since portions other than the shrinkage portion C do not shrink, it is possible to obtain a package 1 having a high decorative effect by adding a pattern or the like to the portion.

  In addition, this invention is not limited only to the said embodiment, A various change in the range which does not deviate from the summary of this invention is possible.

  For example, in the present embodiment, the contraction portion C is composed of the film 9 and the sheet contraction portions 10 and 10, but may be composed only of a film or resin having heat shrinkability. Further, the film 9 is composed of a single film having substantially the same width as the sheet 2, but may be narrower or wider than the sheet 2. Further, a plurality of narrow films may be arranged in the width direction of the sheet 2.

  Moreover, although the opening 8 is formed in this embodiment, this opening 8 does not need to be formed. In this case, when the heat-shrinkable film or the like is thermally shrunk, the sheet 2 at a position facing the film or the like is formed of a flexible material so as not to be the resistance to shrinkage or does not become the resistance to shrinkage. For example, it is preferable to form a plurality of parallel and equally spaced fold lines in the width direction on the sheet 2 at the facing position so that the sheet 2 is easily bent in a bellows shape.

  Further, a broken line in a region corresponding to the opening 8 may be cut out of the broken lines provided to make the bellows bend easily. By forming in this way, such a portion becomes easy to bend due to the bellows shape, and the elastic resistance of the sheet against contraction in the length direction of the film is further reduced.

  Moreover, in this embodiment, although the shrinkage | contraction part C is provided in the middle of the sheet | seat 2, for example, when forming the sheet | seat 2 cyclically | annularly, the shrinking action bodies, such as the film 9, are arrange | positioned between the edge parts of the sheet | seat 2. You may do it. By setting it as such a structure, it becomes possible to change the opening diameter at the time of making it cyclic | annular only by changing the length of a contraction effect | action body, without changing the length of the sheet | seat 2. FIG.

  Further, in the present embodiment, the sheet 2 is formed so that the overlapping portion 7 is located on the side wall 5 of the annular package 1, but even if the sheet 2 is formed so as to be located on the bottom wall 6. Alternatively, it may be formed to be in another position.

The front view which the packaging body concerning this embodiment developed is shown. (A) in a state where the container is accommodated in the packaging body according to the embodiment shows a front view before the contraction portion contracts, and (b) shows a front view after the contraction portion contracts. The front fragmentary sectional view of the container accommodated in the package which concerns on the embodiment is shown.
