Description

[Technical Field]

[0001] The present invention relates to an outer case and a package. [Background technology]

[0002] BACKGROUND ART Box-shaped exterior cases that are formed by assembling paper or resin sheet materials and that can store items are known (for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jikko No. 51-93766 [Patent Document 2] Japanese Patent Application Publication No. 2023-124057 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the case of the outer case of Patent Document 1, in which a flap provided at the insertion opening is simply folded to support an item, the flap for supporting the item opens outward due to the weight of the item, etc., and is not strong enough to hold the item in its stored state.

[0005] Furthermore, in the outer case of Patent Document 2, if the insertion opening is left open, the item may fall out of the outer case due to the weight of the item, etc., and therefore the item cannot be securely held in a stored state. A configuration in which the insertion opening is sealed to securely hold the item is also disclosed, but it is necessary to insert an insertion plate of a restricting plate into an insertion hole in the flap, which makes the operation of storing the item cumbersome.

[0006] An object of the present invention is to provide a cylindrical outer case for storing items, which allows items to be stored with a simple operation and can more reliably restrict movement of the items. [Means for solving the problem]

[0007] The outer case of the present invention is an outer case for storing articles. The outer case is A cylindrical wall; an insertion opening for the article, which is one opening of the cylindrical wall; and at least one flap that is provided on at least a part of the edge of the cylindrical wall on the insertion opening side and that can be folded back toward the inside of the cylindrical wall. The flap has a holding portion for holding the article, and a protruding portion that is integrally adjacent to the holding portion and protrudes a predetermined length beyond the holding portion. The holding portion has an extending portion that extends and protrudes beyond a portion adjacent to the protruding portion. In a storage state in which the article is stored in the exterior case, an end surface of the article on the insertion opening side is spaced apart from an opening surface of the insertion opening on the opposite side to the insertion opening on the outer side of a central portion in a width direction of the flap; The flap is folded inward of the cylindrical wall at the boundary with the cylindrical wall, a tip end portion of the protrusion is sandwiched between the article and the cylindrical wall of the exterior case; The extending portion of the holding portion is located inside the cylindrical wall relative to the protruding portion, and the article is held by the holding portion. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a cylindrical outer case for storing items, which can store items with a simple operation and can more reliably restrict the movement of the items. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or common parts are designated by the same reference numerals.

[0011] 1 and 6 are photographs, substituted for drawings, showing a package 6 including an outer case 1 of the embodiment and an article 5 housed in the outer case 1. FIG. FIG. 2 is a development view of the sheet material 10 forming the outer case 1 of the embodiment. 3 to 5 are photographs showing the exterior case and the like.

[0012] In this specification, terms including "upper" and "lower" may be used, but "upper" and "lower" are based on the state in which the side where the flap 3 is provided (the insertion opening 2c side) is the lower side and the opposite side (the top wall 4 side) is the upper side relative to the direction in which the cylindrical wall 2 extends. However, these terms are used to identify the directions in the outer case 1, and are not limited to the state in which the outer case 1 is used (such as when installed in a store) as the reference. The up-down direction on the paper surface of Figure 1 coincides with the reference state.

[0013] <Outer case> 1 and 6, an outer case 1 of this embodiment is an outer case for storing an article 5. That is, the article 5 is stored inside the outer case 1 (inside the cylindrical wall 2).

[0014] 2 to 5, outer case 1 includes a cylindrical wall 2, an insertion opening 2c, and at least one flap 3. As shown in FIG. The insertion opening 2c is an opening (lower opening) on ​​one side of the cylindrical wall 2, through which the article 5 is inserted. At least one flap 3 is provided on at least a part of (connected to) the edge 2a (lower end) of the cylindrical wall 2 on the insertion opening 2c side. The flap 3 can be folded back to the inside (upper inside) of the cylindrical wall 2 of the exterior case 1 (see FIG. 4).

[0015] (Goods) In the case of the articles that are the subject of the present invention, when stored (Figures 1, 6, and 8(a)), the end face 5a of the article 5 on the side of the insertion opening 2c is spaced further outward from the center in the width direction (horizontal direction in Figure 8) of the flap 3 than from the opening surface of the insertion opening 2c toward the opposite side of the insertion opening 2c (upward in Figure 8).

[0016] The end surface 5a may be a surface at any position when the article 5 is in use, and may be a bottom surface, a side surface, or the like when the article 5 is in use. In this embodiment, the item is a cylindrical container (e.g., a jar) that is relatively thin (its height is smaller than its diameter) and consists of a container body 51 and a lid 52 as shown in Figure 7, and the side surface of the item 5 in its use state (Figure 7) is the end surface 5a on the insertion opening 2c side in the storage state.

[0017] In the container (article 5) shown in FIG. 7, the end surface 5a (side surface of the cylindrical container) is a curved surface (a surface having a rounded outer shape when viewed from above in the state in which the article 5 shown in FIG. 7 is in use (see FIG. 8)). That is, the illustrated container (article 5) has a circular outer periphery when viewed from above in the state in which it is in use, and the end surface 5a is semicircular when viewed from above in the state in which it is in use. However, the present invention is not limited to this, and the end surface 5a of the article 5 (which faces the insertion opening 2c in the stored state) may be an end surface 5a such that the outer side of the center in the width direction (horizontal direction in FIG. 8) of the flap 3 is spaced away from the opening surface of the insertion opening 2c toward the opposite side of the insertion opening 2c. For example, the article 5 may have a polygonal outer periphery when viewed from above in the used state, and the end surface 5a may be a part of the polygonal outer periphery when viewed from above in the used state.

[0018] For example, when the article 5 has side surfaces, a top surface, and a bottom surface in its use state (FIG. 7), and at least a portion of the side surface is the end surface 5a, the shape of the top surface and the bottom surface is not particularly limited, but for example, the top surface and the bottom surface may be flat, may have curved (rounded) edges, or may be curved surfaces overall.

[0019] For example, as shown in FIG. 7, the article 5 may have side surfaces (peripheral surfaces), a top surface, and a bottom surface, and the entire side surfaces (peripheral surfaces) may be circular in top view. That is, the side surface (periphery) of the article may be approximately cylindrical. In this case, the entire side surface of the article is curved. Examples of such articles include cylindrical articles.

[0020] 7. For example, the side surface of the container body 51 and the side surface of the lid 52 may have different shapes, sizes, etc. In this case, in the two flaps 3 shown in the figure, the shapes of the extension portions 31a of the holding portions 31 may be designed to be different shapes so as to conform to the shapes of the end faces 5a (the side surfaces of the container body 51 and the lid 52) that they each hold (see Figures 9(a) and (b)).

[0021] The article 5 is not particularly limited, but may be, for example, a cosmetic container. Such a container is not particularly limited, but examples thereof include resin containers (such as a jar container as shown in FIG. 7) and glass containers.

[0022] (cylindrical wall) The shape of the cylindrical wall 2 is not particularly limited as long as it is cylindrical, but it is preferably angular.

[0023] In the sheet material 10 shown in Figure 2, the tubular wall 2 can be formed by folding the folding line 22a and adhering the adhesive portion 21 provided at one side end of the tubular wall 2 to the other side end of the tubular wall 2. The folding line 22b is not necessarily required, but the cylindrical wall 2 may be folded along the folding line 22b, and the ends of the cylindrical wall 2 may be overlapped, and then the adhesive portion 21 may be attached.

[0024] By inserting an item 5 (cylindrical container) into the insertion opening 2c (see Figure 4), which is one opening of the cylindrical wall 2 (outer case 1), the item 5 is held in the outer case 1 by the function of the flap 3 described below (see Figure 5). That is, the protruding portion 32 of the flap 3 is clamped between the bottom surface (and top surface) of the cylindrical container and the cylindrical wall 2, and the side surface (circumferential surface) of the cylindrical container is held by the extending portion 31a of the holding portion 31 of the flap 3.

[0025] The cylindrical wall 2 may be provided with an opening assisting line 23 for opening (see FIG. 2). For example, if two parallel opening assisting lines 23 are provided along the length of the cylindrical wall 2, the outer case 1 can be easily opened by grasping the end of the portion of the cylindrical wall 2 between the opening assisting lines 23 and removing that portion. The opening assisting line 23 may be formed by a plurality of cut lines as shown in the figure, or may be a perforation, a half-cut line, or the like.

[0026] (flap) The flap 3 is provided on at least a part of the edge (lower end) of the cylindrical wall 2 on the insertion opening 2c side.

[0027] The flap 3 has a holding portion 31 (claw portion) for holding an article 5 (stored inside), and a protruding portion 32 (clamping portion) that is integrally adjacent to the holding portion 31 and protrudes a predetermined length from the holding portion 31. The holding portion 31 has an extending portion 31a that protrudes beyond the portion adjacent to the protruding portion 32. Preferably, the holding portions 31 are provided on both sides of the protruding portion 32 (both sides in the width direction of the flap 3).

[0028] As shown in Figures 1 and 6, when the item 5 is stored in the outer case 1 (hereinafter sometimes simply referred to as the "stored state"), the flap 3 is folded inside the cylindrical wall 2 at the boundary with the cylindrical wall 2 (the base end of the flap 3), and a portion of the tip side of the protrusion 32 is clamped (clamped and fixed) between the item 5 (the outer surface of the item 5) and the cylindrical wall 2 of the outer case 1. This is because the protruding portion 32 protrudes by a predetermined length from the portion of the holding portion 31 adjacent to the protruding portion 32 . In the drawings, the protrusion 32 protrudes further than the extending portion 31a of the holding portion 31, but it does not necessarily have to protrude further than the extending portion 31a of the holding portion 31. Even if the length of the protrusion 32 in the protruding direction is slightly shorter than the outer widthwise portion of the extending portion 31a of the holding portion 31, as long as the protrusion 32 protrudes a predetermined length further than the portion of the holding portion 31 adjacent to the protrusion 32, a portion of the tip side of the protrusion 32 can be clamped between the outer surface of the item 5 and the cylindrical wall 2 of the outer case 1. In other words, the protrusion 32 has a predetermined length (in the protruding direction) required to be clamped between the outer surface of the item 5 held by the holding portion 31 and the cylindrical wall 2 of the outer case 1 in the storage state in which the item 5 is stored in the outer case 1. 6, the extending portion 31a (tip) of the holding portion 31 is not clamped like the protruding portion 32, so it rises up in response to the bending and is positioned more inward than the protruding portion 32, and the article 5 is held by the holding portion 31 (extending portion 31a). In other words, the article 5 is prevented from moving in a direction (downward) that would cause it to fall out toward the insertion opening 2c.

[0029] As described above, in the stored state (Figures 1, 6, and 8(a)), the end face 5a of the item 5 on the side of the insertion opening 2c is spaced further outward from the center in the width direction (horizontal direction in Figure 8) of the flap 3 than from the opening surface of the insertion opening 2c toward the opposite side of the insertion opening 2c (upward in Figure 8). Here, because the two holding portions 31 provided on both sides of the flap 3 in the width direction are provided with extension portions 31a, a force acts on the end surface 5a of the article 5 by the two extension portions 31a provided on both sides in the width direction, pushing the article 5 back from the outside in the width direction of the flap 3 toward the center. As a result, the article 5 is not only prevented from moving downward, but is also held in the center (the center in the width direction of the flap 3) so as not to move in the width direction of the insertion opening 2c (the width direction of the flap 3).

[0030] Referring to FIG. 9, the shape of the extension 31a (the shape of the end in the protruding direction) is preferably a shape that follows the end face 5a on the insertion opening 2c side of the article 5 in the stored state. For example, if the end face 5a is part of a circle in plan view, it is preferable that the shape conform to the end face 5a as shown in Figure 9(a).If the end face 5a is part of a polygon in plan view, it is preferable that the shape conform to the end face 5a as shown in Figure 9(b). In this case, the article 5 can be more reliably prevented from moving in the width direction of the insertion slot 2c. Furthermore, the holding portion 31 (extending portion 31a) has excellent strength for preventing the article 5 from moving downward.

[0031] However, the shape of the extension 31a does not need to be such that it completely fits along the end face 5a of the article 5 on the insertion opening 2c side in the stored state. For example, the shape of the extension 31a may include a recess 31b that is recessed on the opposite side of the protruding direction from the shape that fits along the end face 5a of the article 5. Even if such a recess 31b is present, as long as the part of the extension 31a other than the recess 31b fits along the end face 5a of the article 5 in the stored state, the effect of holding the article so that it does not move downward and in the width direction of the insertion opening 2c is achieved.

[0032] The protruding portion 32 is provided integrally with (connected to) the holding portion 31, and therefore serves to reinforce the holding portion 31. This prevents downward deformation of the holding portion 31, even when stress (such as gravity, vibration during transport, or reaction force when lifting the outer case 1) occurs that causes the item to move downward inside the outer case 1, and the item 5 is securely held in place (restricting movement of the item 5).

[0033] In order to improve the workability of folding the protruding portion 32 (flap 3) and to enable it to be folded at a desired position, an easy-to-fold portion may be provided in at least a portion of the boundary between the protruding portion 32 and the tubular wall 2 in the sheet material 10. The easy-to-fold portion is not particularly limited as long as it is a portion that can be easily folded, and examples of the easy-to-fold portion include half-cut lines (lines with cuts that do not penetrate through the thickness of the sheet), perforations (intermittent cut lines of 2 mm or less), and cut lines (cuts with a predetermined length excluding perforated cuts). In particular, when the width of the protruding portion 32 is long, it is difficult to fold it, so it is preferable to provide an easy-to-fold portion.

[0034] The easy-to-bend portion provided at least in part of the boundary between the protrusion 32 and the cylindrical wall 2 is preferably a cut line 20 provided through the sheet material 10. It is particularly preferable that the cut line be provided over 50% or more of the width of the protrusion. In this case, by folding the protrusion 32 inward, the protrusion 32 is easily positioned along the inside of the cylindrical wall 2, so that when the outer case 1 is attached to the item 5, the protrusion 32 does not interfere with the attachment, and in the stored state, the protrusion 32 is easily sandwiched between the outer surface (of the straight body) of the item 5 and the cylindrical wall 2 of the outer case 1.

[0035] Furthermore, since the cut lines 20 partially separate the protruding portions 32 from the cylindrical wall 2, the stress generated when the protruding portions 32 are folded is dispersed, and the holding portions 31 are less likely to be folded completely, and are slightly raised toward the inside of the cylindrical wall 2. This allows the holding portions 31 to hold the article 5 more reliably.

[0036] Furthermore, even if an easy-to-bend portion other than a cut line such as a half-cut line or a perforation is provided at the boundary between the protrusion 32 and the tubular wall 2, for example, by not providing an easy-to-bend portion at the boundary between the holding portion 31 and the tubular wall 2, the holding portion 31 may not be completely folded, and therefore it is possible for the holding portion 31 (extension portion 31a) to be positioned on the inside when stored.

[0037] That is, it is preferable that the boundary between the holding portion 31 and the cylindrical wall 2 is designed to be more difficult to bend than the boundary between the protruding portion 32 and the cylindrical wall 2. In this case, the holding portion 31 (extending portion 31a) is raised inward, and the holding portion 31 can hold the article 5 more reliably.

[0038] In order to improve the workability of folding the holding portion 31 (flap 3) and enable it to be folded at the desired position, a folding line 20a such as a half-cut line or perforation may be provided on the sheet material 10 at the boundary between the holding portion 31 and the tubular wall 2.

[0039] When the folding line 20a is provided at the boundary between the retaining portion 31 and the cylindrical wall 2, it is preferable that the folding line is not a cut line. If the folding line 20a is a cut line, the retaining portion 31 tends to follow the inner surface of the cylindrical wall 2, and the retaining portion 31 (extending portion 31a) may not easily rise inward relative to the protruding portion 32 that follows the inner surface of the cylindrical wall 2.

[0040] 2, a cut line 20 is provided at the boundary between the protruding portion 32 and the cylindrical wall 2, and a folding line 20a (half-cut line, perforation, pressed crease, etc.) is provided at the boundary between the holding portion 31 and the cylindrical wall 2. In this way, it is preferable that the boundary between the holding portion 31 and the cylindrical wall 2 is designed to be more difficult to fold than the boundary between the protruding portion 32 and the cylindrical wall 2.

[0041] 2, the flap 3 is provided with a plurality of folding assist lines 20b, 20c (half-cut lines, perforations, pressed creases, etc.) extending in the vertical direction near the boundary between the holding portion 31 and the protruding portion 32. When the flap 3 is folded back, the folding assist lines 20b become mountain folds and the folding assist lines 20c become valley folds, causing the holding portion 31 to rise slightly toward the inside of the cylindrical wall 2. This makes it possible to more stably position the extending portion 31a of the holding portion 31 inside the protruding portion 32, thereby more reliably holding the article.

[0042] The number of flaps 3 is not particularly limited and may be one or more. The number of protrusions 32 and the number of holding portions 31 provided on one flap 3 are also not particularly limited. A small number of flaps 3 is preferable in terms of facilitating the work of folding the flaps 3. When there is only one flap 3, it is preferable that there are two holding portions 31 spaced apart from each other in the circumferential direction of the cylindrical wall 2 in order to stably hold the article 5. Therefore, it is preferable to increase the width of the protruding portion 32 and provide holding portions 31 on both sides of the protruding portion 32.

[0043] In the illustrated exterior case 1, the cylindrical wall 2 is a rectangular tube, and the flaps 3 are provided on two opposing sides of the rectangular shape formed by the edge 2a on the insertion opening 2c side. In this case, the article 5 can be stably held and workability is also good. In this way, it is preferable that the flaps 3 are provided at two opposing locations on the edge of the cylindrical wall 2 on the insertion opening 2c side.

[0044] In addition, in the illustrated outer case 1, holding portions 31 are provided adjacent to both sides of the protruding portion 32. In this case, by grasping and folding one protruding portion 32, it is possible to fold in two holding portions 31, which makes it easier to assemble the outer case 1. For example, if two protrusions 32 are provided, the portion connecting these two protrusions 32 is different from the retaining portion 31 of the present invention. When two such protrusions 32 are provided in the center of the flap in the width direction, it is preferable to provide one retaining portion 31 and one extending portion 31a on the outside of each protrusion 32 in the width direction.

[0045] The flap 3 only needs to be folded in before storing the article 5. That is, the flap 3 may be folded in before storing the outer case 1, or may be left unfolded during storage and folded in before use.

[0046] (Top wall) As shown in the figure, the exterior case 1 preferably has a top wall 4 that closes at least a part of the opening (upper opening) of the cylindrical wall 2 on the side opposite to the insertion opening 2c.

[0047] If the outer case 1 does not have a top wall 4, the item 5 can be inserted from the upper opening, and therefore there is no need to use the flap 3 in this embodiment; for example, the insertion opening 2c side of the cylindrical wall 2 can be blocked. However, if the outer case 1 has a top wall 4, the item 5 must be inserted from the insertion opening 2c on the opposite side, and in this case, the mechanism for holding the item 5 with a simple operation using the flap 3 in this embodiment is useful.

[0048] The shape of the top wall 4 in a plan view is not particularly limited, and may be, for example, the same shape (rectangular) as the upper opening of the cylindrical wall 2 in the stored state. The size of the top wall 4 in a plan view may also be approximately the same as or different from the size of the upper opening of the cylindrical wall 2 in the stored state.

[0049] 2, the cylindrical wall 2 is folded along the folding line 22b, and the ends of the cylindrical wall 2 are overlapped, and then the adhesive portion 21 is attached. At this time, the adhesive portion 21a provided at the tip 412 of one flap 41 constituting the top wall 4 is attached to the tip 422 of the other flap 42 constituting the top wall 4. Thereafter, when using the outer case, the cylindrical wall 2 is folded in a mountain fold at the folding line 22a, and at the same time, the flaps 41, 42 are folded in a valley fold at the folding line 4b and in a mountain fold at the folding line 4a, whereby the base ends 411, 421 of the flaps 41, 42 form a top wall 4 that blocks at least a portion of the upper opening of the cylindrical wall 2.

[0050] At least one of the cylindrical wall 2 and the top wall 4 may be printed as desired, if necessary. An opening 2b may be provided in at least one part of the cylindrical wall 2 and the top wall 4 so that a printed marking on the surface of the article 5 can be seen through the opening 2b. Furthermore, the outer case 1 may be formed using a transparent sheet material 10 (such as a resin sheet material) so that the printed display on the surface of the article 5 can be seen through the cylindrical wall 2 or the top wall 4.

[0051] (sheet material) The outer case 1 is formed by assembling sheet materials 10, for example.

[0052] The sheet material 10 forming the outer case 1 is not particularly limited, and various known sheets used for outer cases for storing items can be used.

[0053] The material constituting the sheet material 10 may be paper or resin, but from the viewpoint of reducing the environmental load, paper is preferable.

[0054] Examples of materials for the sheet material 10 include cardboard (including cardboard laminated with a thin synthetic resin film), synthetic resin sheets (including synthetic resin sheets laminated with thin paper), synthetic resin sheets with a metal vapor deposition layer, and laminated sheets of these. It is preferable to use cardboard or synthetic resin sheets because they are relatively inexpensive. Examples of synthetic resins that are materials for synthetic resin sheets include sheets of polyolefin-based resins, polyester-based resins (polyethylene terephthalate, etc.), polystyrene-based resins, (meth)acrylic resins, etc. Examples of polyolefin-based resins include polyethylene-based resins, polypropylene-based resins, cyclic olefin-based resins, and copolymers containing polyethylene. Polypropylene-based resins are preferred because they have appropriate rigidity.

[0055] The thickness of the sheet material 10 is not particularly limited, but is preferably 0.2 to 1.5 mm. For example, the thickness is 0.5 to 1.5 mm in the case of cardboard, and 0.2 to 0.6 mm in the case of a synthetic resin sheet.

[0056] There are no particular limitations on the shape of the sheet material 10 (developed view of the outer case 1) used to assemble the outer case 1. The sheet material 10 may have one or more attachment portions (glue portions 21, 21a) for forming the outer case 1.

[0057] Any of the corners of the sheet material 10 (for example, the corners at both ends of the protruding portion 32, the corners at both ends of the flap 3, and the step between the holding portion 31 and the protruding portion 32) may be rounded (may be rounded) (see FIG. 2, etc.). The rounded shape makes it less likely for fingers to get caught when assembling the outer case 1, improving workability and safety. In particular, it is preferable that the step portion between the holding portion 31 and the protruding portion 32 has a rounded shape. Since the holding portion 31, which is subjected to the most stress from the article 5, is supported by the protruding portion 32, there is a possibility that the holding portion 31 and the protruding portion 32 may break, but if the step portion between the holding portion 31 and the protruding portion 32 has a rounded shape, breakage of the holding portion 31 and the protruding portion 32 is suppressed.

[0058] <Package> The present invention also relates to a package 6 (item with outer case) that includes the above-mentioned outer case 1 and an item 5 stored in the outer case 1. If a package 6 (item with outer case) in which an item is stored in an outer case 1 is prepared in advance, the package 6 can be displayed and sold as is on a display shelf or the like, or can be transported, carried, stored, etc.

[0059] In this way, there is no particular limit to the number of items stored in the outer case 1, and one item or multiple items may be stored. For example, two items 5 stacked vertically may be stored in the outer case 1. The multiple items may be the same item or different items. When multiple items are stored, when the multiple items are combined, the end face of the entire item (as a whole) on the side of the insertion opening 2c should be spaced away from the opening surface of the insertion opening 2c on the opposite side of the insertion opening 2c, outside the center in the width direction of the flap 3.

[0060] In the illustrated packaging body 6, normally, when the packaging body 6 (stored state) is in a state where the edge 2a (lower end) of the outer case 1 (cylindrical wall 2) on the insertion opening 2c side is located lower than the end face 5a (lower end face) of the item 5 on the insertion opening 2c side (see Figure 8(a)).

[0061] In the stored state, the article 5 is held by the holding portion 31 (extending portion 31a) at the end surface 5a on the insertion opening 2c side.

[0062] The outer case 1 (sheet material 10) may be provided with a hanging hole 1a for hanging the package 6. Furthermore, the exterior case 1 (sheet material 10) may be provided with an opening 2b that allows the stored article 5 to be visible.

[0063] <How to use> The method for storing the item 5 inside the outer case 1 is not particularly limited, but one example is to store the item inside the outer case 1 by inserting the item from below into the insertion opening 2c (lower opening) of the outer case 1 and pushing the item up (see Figure 8(b)).

[0064] When storing an item, the retaining portion 31 is temporarily pushed toward the cylindrical wall 2 by the item, but after the retaining portion 31 is folded, when the item passes upward through the retaining portion 31 (see FIG. 8(b)), the extending portion 31a of the retaining portion 31 returns to the inside of the cylindrical wall 2 again. This restricts the item from moving downward thereafter (see FIGS. 8(a) and 6). Note that the protruding portion 32 is sandwiched between the outer surface of the item and the cylindrical wall 2 and supports the retaining portion 31 from above, so that the retaining portion 31 has sufficient strength to withstand the stress of the item attempting to move downward.

[0065] To enable such insertion and storage of items, it is preferable to design the outer case 1 so that the height H1 (depth from the insertion opening 2c) of the storage space in the outer case 1 is slightly (for example, about 1 to 10 mm) longer than the height H2 of the stored item 5 (the vertical length of the item when stored).

[0066] The height H1 of the storage space of the outer case 1 is the vertical distance from the highest position (upper limit position) at which the article 5 can be inserted to the edge 2a (lower end) of the cylindrical wall 2 on the insertion opening 2c side. For example, if the exterior case 1 has a top wall 4, the upper limit position is the position of the underside of the top wall 4 (see FIG. 8(b)). Also, for example, if the exterior case 1 has a limiting part (limiting mechanism) other than the top wall 4 that limits the upward movement of the article 5, the upper limit position is the position of the limiting part (the uppermost position at which the article 5 can be inserted under the restriction of the limiting part). The limiting portion is not particularly limited, but may be, for example, a protrusion provided on the cylindrical wall 2 and protruding inward of the cylindrical wall 2. Alternatively, for example, the cylindrical wall 2 may be designed so that the storage space of the cylindrical wall 2 is narrower at the top than at the bottom (the length in any direction in the cross section is shorter), and a limiting mechanism may be provided that limits the uppermost position at which the article 5 can be inserted (see FIG. 10 described later).

[0067] More specifically, it is preferable that the height H1 of the storage space of the outer case 1 is designed relative to the height H2 of the stored item 5 so that when the item 5 is inserted from the insertion opening 2c (edge ​​2a side) and pushed up to an upper limit position on the top wall 4 or the like (see Figure 8(b)), the end face 5a of the item 5 on the insertion opening 2c side goes over the extension portion 31a of the flap 3 but does not go over the tip 32a (in the protruding direction) of the protruding portion 32. As a result, by simply inserting and pushing the item 5 through the insertion opening 2c, the protruding portion 32 of the flap 3 is clamped between the item 5 and the cylindrical wall 2, and the holding portion 31 (extension portion 31a) of the flap 3 is raised inside the cylindrical wall 2, so that the movement of the item 5 can be more reliably restricted with a simple storage operation.

[0068] It is preferable that the size of the outer case 1 (height of the cylindrical wall 2, length of the protruding portion 32 and the holding portion 31 in the protruding direction, etc.) be designed so that the gap between the top wall 4 and the item 5 is small when the packaging body 6 (stored state) is in a stored state. In this case, vertical movement of the article 5 inside the exterior case 1 is minimized, and the article 5 can be held securely.

[0069] However, if the gap between the top wall 4 and the item 5 is too narrow, the friction between the item 5 and the outer case 1 will be large when inserting the item 5 (see Figure 5), and the item 5 may not be stored (inserted) smoothly.

[0070] In this embodiment, the side surface of the cylindrical wall 2 (external case 1) is folded so that a folding line 22b near the center in the thickness direction (direction perpendicular to the paper surface of FIG. 8) protrudes outward (see FIGS. 3 and 4). This allows the length of the outer case 1 in the thickness direction to increase in accordance with the thickness of the item 5. As a result, when inserting the item 5 (see FIG. 5), the frictional force between the item 5 and the outer case 1 is reduced, allowing the item 5 to be stored (inserted) smoothly. Furthermore, if the sides of the outer case 1 are folded sufficiently at the folding lines 22b, the elastic force of the outer case 1 trying to return to its folded, thin state will cause the outer case 1 to adhere closely to the item 5 in a manner sandwiching the item 5 in the thickness direction when stored, thereby preventing the item 5 from moving in the thickness direction relative to the outer case 1 and allowing the item 5 to be held stably. Furthermore, even if folding line 22b is not provided on the side of outer case 1, movement of item 5 in the thickness direction can be prevented by making the thickness direction length of outer case 1 approximately the same as the thickness of item 5, but this may increase the friction force between item 5 and outer case 1 when inserted, making it difficult to store item 5 smoothly.

[0071] When stored before use, the outer case may be folded along two opposing folding lines 22b that extend in the length direction of the cylindrical wall 2. In this case, the outer case can be stored in a space-saving manner. From the viewpoint of ease of folding, the folding line 22b is preferably provided in a portion other than the portion where the flap 3 is provided in the circumferential direction of the cylindrical wall 2 (the longitudinal direction of the cylindrical wall 2 in FIG. 2).

[0072] <<Modified outer case>> Fig. 10 is a development view of a sheet material 10 forming a modified example of the outer case 1. Fig. 11 is a vertical cross-sectional view showing a modified example of the outer case 1. In this modification, the configuration of the top wall 4 of the exterior case 1 differs from that of the above embodiment. In this modification, the top wall 4 is made up of two sheets of material extending obliquely upward from the stored article 5 (the portion of the cylindrical wall 2 above the stored article 5). Here, by curving the folding line 22a, the cylindrical wall 2 is designed so that the storage space of the cylindrical wall 2 is narrower at the top than at the bottom (the length in the short direction in the cross section (horizontal direction in FIG. 11) is shortened). For this reason, the uppermost position at which the article 5 can be inserted (the position of the upper end of the article 5) is limited to be approximately the same as the top wall 4 of the exterior case 1 shown in FIG. 2 etc. (see FIG. 11). In other respects, the outer case is basically the same as the outer case of the above embodiment.

[0073] In this modification, the area of ​​the outer surface of the cylindrical wall 2 is large, so that the area of ​​the printed portion can be made large.
