Description

  The present invention relates to a packaging sleeve and a packaging body including the packaging sleeve.

  In the packaging of food and the like, the contents may be filled in a resin container or the like, and the resin container may be covered with a packaging sleeve.

  Resin containers have the advantages of excellent sealing performance and good sealing at the flanges, but have the disadvantage of having a beautiful print on the outer surface.

  Paper containers have the advantage that they can be printed beautifully on the outer surface, but have the disadvantage that air and contents may leak from fine pinholes during long-term storage. Further, when the lid is closed after filling the contents, there is a possibility that a seal failure may occur at the seam step of the flange.

  Therefore, in order to take advantage of both advantages, a packaging body in which a paper sleeve (exterior body) subjected to gravure printing or the like is provided on the outer periphery of a resin container has been proposed. That is, paper is used for the packaging sleeve.

  By the way, in the packaging body for foods and the like, the area of the upper surface and the lower surface is larger than the thickness (height). That is, it becomes flat. Therefore, beautiful printing is performed on the top plate of the packaging sleeve.

  On the other hand, when flat products (packaging bodies) are displayed in stores, they are generally stacked. In a flat display, more products can be placed, but since the direction of the printing surface (top plate) and the line of sight of the consumer do not match, only eye catching by side printing can be obtained, and eye catching effect by printing Is not fully demonstrated.

  In order to enhance the eye-catching effect at the store, a surface display in which the product is self-supporting and the printed surface matches the consumer's line of sight is desired. However, in general, the resin container has a taper that decreases from the top to the bottom, and the packaging sleeve has a shape corresponding to the resin container. That is, the side surface serving as the ground contact surface when standing is inclined and is smaller than the bottom surface. Therefore, it is difficult to make the product independent.

  On the other hand, the technique regarding the surface display which makes goods self-supporting and makes a printing surface correspond with a consumer's eyes | visual_axis is proposed (for example, patent document 1 or patent document 2).

  The packaging sleeve of Patent Document 1 includes a top plate, two side plates, and a bottom plate. The bottom plate is provided with connecting means. By the connection, a packaging sleeve is formed so as to cover the entire circumference of the container. A cut is provided between the side plate and the bottom plate so as to protrude from the folded portion toward the side plate. That is, a part of the bottom plate protrudes outward due to the cut. For the surface display, the protrusions act as legs. Thereby, a sufficient eye catching effect can be expected.

  The packaging tool of patent document 2 is provided with the support body connected with a top plate and a top plate. The top plate and the support are continuous through the folds, and a part of the support is bonded to the top plate. An insertion slit is provided between the top plate and the support, and the flange of the container is inserted into the insertion slit so that the packaging tool and the container are integrated. With respect to the surface display, the bottom surface of the support serves as a ground contact surface during self-supporting. Thereby, a sufficient eye catching effect can be expected.

  However, the packaging sleeve of Patent Document 1 and the packaging tool of Patent Document 2 have the following problems.

  The packaging sleeve of patent document 1 makes the connection means in a bottom plate an essential structure. Without the connecting means, the packaging sleeve and the container are not integrated. However, since the bottom plate has the next largest area after the top plate, if the bottom plate is provided, a paper sheet having a larger area is required in the developed state (blank).

  The packaging tool of patent document 2 makes adhesion an essential process. If there is no adhesion, the packaging and container will not be integrated. However, as a result, the manufacturing cost is increased and the manufacturing speed is lowered, which is not preferable. Moreover, it becomes bulky when it is discarded after use. To reduce the volume, it is necessary to peel off the adhesive. Furthermore, when the contents are food, the odor of the adhesive is often regarded as a problem.

  That is, it is important to consider how to integrate the packaging sleeve and the container as a premise for the self-supporting packaging (product).

  SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, reduces the sheet area to be used, enables the packaging sleeve and the container to be reliably integrated without requiring adhesion, and enables the product to stand on its own. The object is to provide a sleeve.

  In order to achieve the above object, the present invention provides a packaging sleeve for packaging a container, and a top plate provided so as to correspond to the upper portion of the container, and one of the top plates via a first folding portion. A first side plate that is provided continuously, a second side plate that is provided continuously with the other of the top plate via a second folding portion, and a third plate that is provided continuously with the first side plate via a third folding portion. And a cut (third cut) provided between the first side plate and the third plate so as to protrude from the third fold portion toward the first side plate, and the third plate is in a blank state. And a locking portion that protrudes toward the first side plate from the third folding portion, and a leg portion that is continuous with the locking portion and that is connected to the first side plate via the third folding portion. Have

  In order to achieve the above object, the present invention provides a packaging sleeve for packaging a container, and a top plate provided so as to correspond to the upper portion of the container, and one of the top plates via a first folding portion. A first side plate that is provided continuously, a second side plate that is provided continuously with the other of the top plate via a second folding portion, and a third plate that is provided continuously with the first side plate via a third folding portion. The third plate stands upright with a locking portion protruding inward from the third folding portion so as to be locked to the bottom surface of the container in a state in which the container is packaged. A leg portion protruding outward from the third fold portion.

  By engaging the third folding part, the locking part and the leg part are formed simultaneously.

  The locking portion is locked to the bottom surface of the container. The packaging sleeve and the container are integrated. The leg part makes the top plate (printing surface) stand up in a state where the container is packaged by grounding the end part. At this time, since there is no bottom plate, the sheet area to be used can be reduced. Adhesion is also unnecessary.

  In the above invention, preferably, the third folding portion has a gradient that rotates the locking portion toward the bottom surface of the container.

  Thereby, a latching | locking part is latched to a container bottom face more reliably.

  Preferably, in the above invention, the packaging sleeve packages the flanged container. A first cut provided at the center of the first fold, and a first cut provided at both ends of the first cut and cut so as to protrude toward the top plate from the first cut. A flange clasp, a second cut provided at the center of the second fold, and formed at both ends of the second cut and cut so as to protrude from the second cut to the top plate side. A second flange clasp.

  Thereby, a latching | locking part is latched to a container bottom face more reliably, and also ensures integration of a container and a packaging sleeve.

  In order to achieve the above-mentioned object, the present invention provides a packaging sleeve for packaging a container with a flange, the top plate provided so as to correspond to the upper part of the container, and the top plate via a first folding part. A first side plate provided on one side, a second side plate provided on the other side of the top plate via a second folding portion, a first cut provided in the center of the first folding portion, and the first A first flange stop provided at both ends of the first cut and formed by being cut so as to protrude from the first cut toward the top plate side, and a second cut provided at the center of the second folding portion And a second flange clasp that is provided at both ends of the second cut and is cut and formed so as to protrude from the second cut toward the top plate.

<Embodiment>
~ General configuration / action ~
The schematic configuration and operation of the embodiment of the present invention will be described. 1 and 2 are diagrams showing a schematic configuration of the packaging sleeve according to the present embodiment. FIG. 3 is a view showing a state of the package immediately before the integration of the container and the packaging sleeve.

  The packaging sleeve 10 is developed into a single sheet (blank) (see FIG. 1) and is formed by folding at a folding portion (see FIG. 2). Furthermore, a package is formed by covering the container 50 with the packaging sleeve 10 (see FIG. 3).

  The container 50 is a resin container, for example. Other materials such as aluminum foil may be used as long as the contents can be filled. The content is, for example, food, but may be other content.

  In the case of illustration, the container 50 has a substantially rectangular bottom surface 51, a side surface 52 rising from the bottom surface 51, and a flange 53 protruding to the outer periphery at the upper end of the side surface 52. The side surface 52 has a taper that decreases from top to bottom. Chamfered portions 54, 54, 55, 55 are formed so as to chamfer the four corners of the flange 53 in a curved shape. The opening of the container 50 is sealed with a film (not shown).

  The packaging sleeve 10 is made of paper, for example. Other materials may be used as long as they can be folded and cut easily and printing is easy. A laminate coating (preferably a film having water resistance or water repellency) made of a polymer or the like may be applied to the paper surface (preferably the outer surface but may be both surfaces). In addition, it is possible to perform precise and beautiful printing on the paper surface in advance using the ease of printing on paper products.

  The packaging sleeve 10 is configured to cover the container 50. That is, the top plate 1, the two side plates 2 and 3, and the special plate (third plate) 4 are developed on one paper sheet.

  The top plate 1 faces the opening of the container 50. The side plate 2 is connected to one side of the top plate 1 via the fold lines 11, 11, 12, 12 and the adjustment surfaces 5, 5. The side plate 3 is connected to the other side of the top plate 1 through the folds 21, 21, 22, 22 and the adjustment surfaces 6, 6. The folds 11, 11, 12, 12 and the adjustment surfaces 5, 5 constitute a first fold portion. The folds 21, 21, 22, 22 and the adjustment surfaces 6, 6 constitute a second fold part.

  A cut (first cut) 13 is provided along the first fold at the center of the boundary (first fold) between the top plate 1 and the side plate 2. A cut (second cut) 23 is provided in the center of the boundary (second fold) between the top plate 1 and the side plate 3 along the second fold.

  The cut 13 is cut at the center and both ends so as to protrude from the cut 13 to the top plate 1 side. The cut 23 is cut at the center and both ends so as to protrude from the cut 23 toward the top plate 1.

  When the fold lines 11, 11, 12, 12 are mountain-folded (shown by broken lines), the cut line 13 forms a slit 14. Accordingly, the protrusion at the center of the cut 13 forms a center flange member 15, and the protrusions at both ends of the cut 13 form end flange clips (first flange clips) 16, 16. When the fold lines 21, 21, 22, and 22 are folded in a mountain, the cut line 23 forms a slit 24. Accordingly, the projection at the center of the cut 23 forms a center flange engagement 25, and the projections at both ends of the cut 23 form end flange clips (second flange clips) 26, 26.

  The special plate 4 (third plate) is connected to the side plate 2 via the fold lines 31 and 31 (third fold portion). The special plate 4 has a locking portion 34 and a leg portion 35.

  In the center of the boundary (third fold) between the side plate 2 and the special plate 4, a cut (third cut) 32 is provided. The cut 32 is cut so as to protrude from the folds 31, 31 toward the side plate 2.

  The locking portion 34 is formed corresponding to the cut 32. That is, the locking portion 34 protrudes from the fold line 31 toward the side plate 2 in the blank state. The leg portion 35 is continuous with the locking portion 34 and is connected to the side plate 2 through the fold line 31.

  When the fold line 31 is valley-folded (the dashed line in the figure), the cut line 32 forms an opening 33, and the protrusion at the center of the cut line 32 forms a locking part 34 that protrudes inward (towards the container) from the fold line 31. To do. On the other hand, a region of the special plate 4 other than the locking portion 34 forms a leg portion 35 that protrudes outward (in a direction away from the container) from the fold line 31.

  The locking portion 34 is locked to the container bottom surface 51. The leg 35 raises the top plate 1 in a state where the container 50 is packaged by grounding its end.

-Detailed configuration and action-
The detailed configuration and operation of this embodiment will be described with reference to FIGS. 4 to 6 will be referred to for the configurations that are not sufficiently illustrated in FIGS.

  FIG. 4 is a diagram showing a detailed configuration of the package according to the present embodiment. The package is formed by integrating the packaging sleeve 10 and the container 50.

  One side of the container flange 53 protrudes through the slit 14. At that time, the center flange member 15 is locked to the back side of the return portion of the container flange 53 (not shown). Further, the end flange clasps 16 and 16 are brought into contact with the chamfered portions 54 and 54. Similarly, one side on the opposite side of the container flange 53 is inserted through the slit 24 and protrudes. At that time, the center flange engagement member 25 is locked to the back side of the return portion of the container flange 53. Furthermore, the end flange clasps 26 and 26 are in contact with the chamfered portions 55 and 55. In addition, it can be locked even on the back side of the flange without the return portion.

  On the other hand, the locking portion 34 is locked to the container bottom surface 51. Thereby, the packaging sleeve 10 and the container 50 are reliably integrated.

  When the package is formed by the locking by the locking portion 34, the leg portion 35 protrudes in the container outward direction (the direction away from the container). When the flange 53 protruding from the slit 14 and the leg portion 35 are grounded, the packaging body is self-supporting so that the printing surface of the top plate 1 matches the consumer's line of sight.

  The angle formed between the top plate 1 and the ground plane is preferably less than 90 degrees. The angle formed between the top plate 1 and the ground contact surface can be adjusted by the length of the leg portion 35 (the distance from the fold line 31 to the leg 35 ground contact end).

  When the angle formed between the top plate 1 and the ground contact surface is less than 90 degrees, a part of the weight of the contents acts in the bottom direction (right direction in the drawing). A reaction occurs in the locking portion 34. Thereby, the latching | locking part 34 is latched to the container bottom face 51 more reliably.

  When the packages are stacked, the weight of the contents acts in the bottom direction, and the locking portion 34 is more reliably locked to the container bottom surface 51 (not shown).

  FIG. 5 is a diagram showing a detailed configuration of the third folding portion (folds 31, 31) according to the present embodiment. The left and right folds 31, 31 shown in the figure have a slight gradient from the outer edge toward the side of the cut 32 toward the side plate 2. For convenience of explanation, the gradient is emphasized in the drawing.

  When the folds 31, 31 are valley-folded, the rotation (first rotation) in the direction of returning the valley fold acts due to the elasticity of the sheet. At that time, the first rotation is biased by the gradient.

  FIG. 6 is a diagram for explaining the effect of the rotating operation according to the present embodiment. Due to the action of returning the valley fold and the gradient of the folds 31, 31, a first rotation (counterclockwise in the figure) is urged around the folds 31, 31, and the locking portion 34 is rotated in the direction of the container bottom 51. Thereby, the latching | locking part 34 is latched to the container bottom face 51 more reliably.

  Subsequently, the second rotation will be described based on FIGS. 3 and 6.

  As described above, one side of the container flange 53 protrudes through the slit 14, the center flange engagement 15 is locked to the back side of the return portion of the container flange 53, and the end flange clamps 16, 16 are chamfered. It abuts on the parts 54 and 54.

  The contact between the end flange clasps 16 and 16 and the chamfered portions 54 and 54 acts to push both ends of the side surface 2 toward the container. That is, the rotation (second rotation) that brings the side surface 2 closer to the container side around the vicinity of the first folding portion (folds 11, 11, 12, 12, adjustment surfaces 5, 5) is biased. The locking portion 34 is rotated toward the container bottom surface 51 via the side surface 2 by the second rotation (counterclockwise in the drawing). Thereby, the latching | locking part 34 is latched to the container bottom face 51 more reliably.

  In the example shown in the figure, the end flange retainers 16 and 16 are in contact with the chamfered portions 54 and 54, but even if they are in contact with the straight portion of the flange 53, the second rotation occurs.

  Returning to FIG. 3, another operation of the end flange clasps 16 and 16 and the end flange clasps 26 and 26 will be described.

  Due to the contact between the end flange clamps 16 and 16 and the chamfered portions 54 and 54, the end flange clamps 16 and 16 become the outermost edge of the container flange 53 (in the case of FIG. 3, the container flange 53 between the chamfered portions 54 and 54. It is located on the inner side (direction approaching the container center) from the straight line part. As a result, the container flange 53 is restrained between the end flange clasps 16 and 16.

  The end flange clamps 26 and 26 also restrain the container flange 53 in the same manner as the end flange clamps 16 and 16. Thereby, the shift | offset | difference of the container of a 1st fold part and a 2nd fold part parallel direction is suppressed.

  Next, the operation of the adjustment surfaces 5 and 5 and the adjustment surfaces 6 and 6 will be described.

  In the present embodiment, the first fold portion is composed of the fold lines 11, 11, 12, 12 and the adjustment surfaces 5, 5, but the first fold portion may be composed of only the fold lines 11, 11. .

  However, in the case of only the folds 11 and 11, the chamfered portions 54 and 54 hit the side plate 2 in the vicinity of the folds 11 and 11, and the side plate 2 is pushed outward (in a direction away from the side surface of the container). The opposite force acts.

  On the other hand, in the present embodiment, the adjustment surfaces 5 and 5 are formed by the fold lines 11, 11, 12, and 12.

  Since the adjustment surfaces 5 and 5 are formed so as to be directed outward from the top plate 1 toward the side plate 2 (a direction away from the side surface of the container), the contact between the side plate 2 and the chamfered portions 54 and 54 can be avoided. Therefore, the second rotation is not hindered.

  Further, the inner pieces (sides close to the container) of the adjustment surfaces 5 and 5 are in contact with the chamfered portions 54 and 54. The adjustment surfaces 5 and 5 also restrain the container flange 53 similarly to the end flange clasps 16 and 16. Thereby, the shift | offset | difference of the container of a 1st folding part parallel direction is suppressed.

  The operation of the adjustment surfaces 6 and 6 is the same as that of the adjustment surfaces 5 and 5.

~effect~
The effect of this embodiment will be described.

  The packaging body is self-supporting by the legs 35. Thereby, the printing surface of the top plate 1 and the line of sight of the consumer coincide. A sufficient eye-catching effect can be expected from the display.

  Due to the locking structure of the locking portion 34 and the container bottom surface 51, the packaging sleeve 10 and the container 50 are integrated. That is, no bottom plate is required. Compared with a packaging sleeve having a bottom plate, the sheet area to be used can be reduced.

  In addition, since the packaging sleeve 10 and the container 50 are integrated with each other, no adhesion is required, so that no problems relating to adhesion occur.

  By the first rotation due to the gradient of the fold lines 31, 31, the locking portion 34 is more securely locked to the container bottom surface 51.

  Due to the second rotation due to the contact structure between the end flange holders 16 and 16 and the chamfered portions 54 and 54, the locking portion 34 is more reliably locked to the container bottom surface 51.

  The abutting structure between the end flange clasps 16 and 16 and the chamfered portions 54 and 54 and the abutting structure between the end flange clasps 26 and 26 and the chamfered portions 55 and 55 are parallel to the first folding portion and the second folding portion. Suppresses the displacement of the container. This also ensures the integration of the packaging sleeve 10 and the container 50.

  The adjustment surfaces 5, 5 and the adjustment surfaces 6, 6 prevent the second rotation hindrance and suppress the displacement of the container in the first fold portion and the second fold portion parallel direction. This also ensures the integration of the packaging sleeve 10 and the container 50.
