Description

[Technical field]

[0001] The present invention relates to a sleeve-type package, and more particularly to a sleeve-type package that can hold a flanged container having a flange around the periphery of its opening, filled with desserts and sealed, without allowing the flanged container to fall out. [Background technology]

[0002] Conventionally, sleeve-type packages have been used to package flanged containers, such as cup-shaped containers, filled and sealed with desserts such as yogurt, pudding, and various jellies. Sleeve-type packages can protect products from external pressure received when the product is dropped, and can enhance sales promotion effects by displaying information, designs, and the like on the sleeve-type package used for packaging. Furthermore, because the sleeve exposes the sides of the flanged container, this package gives consumers a sense of security.

[0003] In such a sleeve-type package, for example, a cut line is provided at the corner where the top plate and the side plate meet, and the side plate is bent to form a flange insertion groove into which the flange of the cup container is inserted and held (for example, see Patent Document 1). However, when the product is turned on its side, sometimes the flange of the cup container comes out of the flange insertion groove of the sleeve-type package, causing the cup container to fall out.

[0011] Fig. 1 is a development view of a blank showing an example of the sleeve-type package according to the present invention, and Fig. 4 is a plan view and a cross-sectional view showing a state in which a flanged container is held in the sleeve-type package according to the present invention. The flanged container that is the subject of the sleeve-type package of the present invention comprises a plastic or paper container body and a lid, the container body having a bottom, side surfaces rising from the peripheral edge of the bottom, an upper opening, and a flange facing outward from the peripheral edge of the upper opening, the container body being filled with contents such as food, for example, and covered with a lid made of a laminate film having sealing properties, and the laminate film being sealed to the flange of the container body.

[0012] Blank 1 shown in Figure 1 is assembled into a sleeve-type package P, which is used to hold a flanged container V, as shown in Figure 4. Blank 1 consists of a sheet of paperboard on which a product description, design, etc., has been printed, and which is punched out to a predetermined shape and size.

[0013] 1, from the top, a bottom panel 11, a side panel 12, a top panel 13, a side panel 14, and a retaining panel 15 are connected via fold lines a, b, c, and d. The retaining panel 15 has a fixed portion 16 and a movable portion 17 connected via fold line e, and the fixed portion 16 is connected to the side panel 14 via fold line d.

[0014] The fixed portion 16 of the retaining panel 15 is overlapped with the bottom panel 11 and fixed with an adhesive when the sleeve-type package P is assembled. The movable portion 17 has an arch-shaped cutout portion 17a at the center of the left and right sides, with the chord portion positioned on the fold line e. The cutout portion 17a is formed so that the lower portion of the container body of the flanged container V can be inserted into it. As will be described later, the portion of the movable portion 17 other than that connected to the fixed portion 16 is a free end, and is movable around the fold line e as a rotation axis.

[0015] A roughly U-shaped insertion notch 18 is provided in the center of fold line b where side panel 12 and top panel 13 are connected, into which part of flange Vf is inserted when flanged container V is packaged. The closed U-shaped portion of insertion notch 18 protrudes slightly into the side panel 12, and the left and right leg portions protrude slightly into the top panel 13. Fold line e is divided by insertion notch 18, and fold line e does not exist in the area surrounded by the U-shaped notch of insertion notch 18.

[0016] Next, the assembly of the sleeve-type package P will be described. The sleeve-type package P is assembled by folding the blank 1 shown in Fig. 1 along the fold lines a, b, c, d, and e. First, the movable part 17 is folded along the fold line e and placed on the fixed part 16. Furthermore, the side panel 14 and the fixed part 16 are folded integrally along the fold line c, and the movable part 17 and the side panel 14 are placed on the top panel 13. Next, the bottom panel 11 is folded along the fold line a and placed on the fixed part 16 and the top panel 13, and the inner surface of the bottom panel 11 and the outer surface of the fixed part 16 are bonded together with an adhesive or the like, completing the folded sleeve-type package (not shown).

[0017] When the fold lines a and c of the sleeve-type package in the folded state are pushed inward so that they approach each other, the side panel 12 and the top panel 13 are folded along the fold line b, and the side panel 14 and the bottom panel 11 are folded along the fold line d, and the box is raised from the folded state to complete the sleeve-type package P. Figure 2 shows this state, with (a) being a perspective view and (b) being a side view, and in Figure 2(b) the front and back surfaces of the paper surface are open to form the square cylindrical sleeve-type package P.

[0018] When the box is erected, the area surrounded by the insertion slits 18 is located on the same plane as the top panel 13, and the U-shaped portion protrudes slightly outward. The portion where the insertion slits 18 protrude into the side panel 12 forms a strip-shaped insertion opening 12a in the side panel 12.

[0019] When the box is erected as shown in FIG. 2, the free end side of the movable portion 17 of the holding panel 15 rises from the folded state due to the rigidity of the paper, with the folding line e as an axis, to form an inclined surface.

[0020] Next, a method for packaging a flanged container V with a sleeve-type package P according to the present invention will be described with reference to Fig. 3. Fig. 3 is shown in a side view. First, the sleeve-type package P, which has been raised as shown in Fig. 3(A), and the flanged container V are prepared. The flanged container V consists of a plastic or paper container body and a lid, and the container body has a bottom surface Vb, a side surface Vs rising from the periphery of the bottom surface Vb, an upper opening, and a flange Vf facing outward from the periphery of the upper opening. The container body is filled with contents such as food, and is covered with a lid made of a laminate film with sealing properties, and the top surface Vt is formed by sealing the laminate film constituting the lid to the flange Vf of the container body.

[0021] The flanged container V is slid and inserted into the sleeve-type package P while applying pressure to the movable part 17, which has become a rising inclined surface due to the box-raising process, so that it overlaps with the fixed part 16. When the sliding insertion starts, the movable part 17 is pressed only by the weight of the flanged container V. When the sliding insertion further progresses and the flanged container V reaches the position of the notch part 17a (see FIG. 2), the pressure on the movable part 17 is released, the container body of the flanged container V is fitted into the notch part 17a, and the movable part 17 is inclined. Also, a part of the flange Vf is inserted into the insertion port 12a (see FIG. 2). The movable part 17 is swung toward the top panel 13 with the folding line e as an axis due to the repulsive force caused by the rigidity of the paperboard, and as a result, the movable part 17 exerts a force that pushes the flanged container V in the direction indicated by the arrow as shown in FIG. 3(c), and the flanged container V is pressed against the side panel 12 (locking effect). Therefore, the flanged container V can be held without falling out of the sleeve-type package P.

[0022] The cardboard used for the sleeve-type package P can be coated cardboard, uncoated cardboard, kraft cardboard, etc., and the basis weight is 200 g / m 2 More than 400g / m 2 In order to improve the aesthetic appeal of the sleeve-type package P, metallized paper made by depositing aluminum on paperboard can be used. The basis weight is 200 g / m 2 If the locking effect is insufficient, the repulsive force of the movable part 17 decreases. Furthermore, when it is desired to impart high designability, a plastic film such as polyethylene terephthalate or the like, or such a film vapor-deposited with aluminum, may be laminated to the paperboard.

[0023] 4 shows a state in which a flanged container V is held in a sleeve-type package P according to the present invention, where (A) is a plan view and (B) is a cross-sectional view taken along line AA. In a package in which a flanged container V is packaged in a sleeve-type package P, the top surface Vt of the flanged container V is covered by a top panel 13, the side surface Vs is covered by opposing side panels 12 and 14, and the bottom surface Vb is covered by a bottom panel 11. The opposing side surface Vs in the direction perpendicular to the direction in which the covered side surfaces Vs face is exposed. Note that, although a circular cup container has been exemplified as the flanged container V, it is not limited to a circular shape and may be an elliptical shape.

[0024] The top surface Vt of the flanged container V is covered with a substantially circular lid having a knob that bulges outward in part, and the flanged container V is stored so that the knob is located in the direction of the opening of the sleeve-type package P. Regarding the side panels 12 and 14 of the flanged container V, the container body of the flanged container V on the side panel 14 side is fitted into the notch 17a provided in the movable part 17. On the side panel 12 side, the flange Vf is inserted into the insertion opening 12a, and the flanged container V is pushed in the direction shown by the arrow by the repulsive force of the movable part 17 trying to rise, and the flanged container V is held in a fixed state by the notch 17a, the insertion opening 12a, and the movable part 17, so that the flanged container V can be prevented from falling out of the sleeve-type package P even if the product is turned sideways.

[0025] The embodiments described so far are representative of the sleeve-type package according to the present invention, and the sleeve-type package according to the present invention is not limited to these, and includes those that do not deviate from the spirit of the present invention. As long as the flanged container V has a flange, the container body and the lid may be separate members. Also, for example, the container body and the lid may be a molded product that are integrated with each other via a hinge. The contents stored in the flanged container may be not only dessert foods such as yogurt, pudding, and various jellies, but also disposable contact lenses, household goods, and the like.
