Description

[Technical Field]

[0001] The present invention relates to a paper spoon used to scoop and remove granular or powdered materials from a container or bag containing the granular or powdered materials. [Background technology]

[0002] 2. Description of the Related Art Conventionally, plastic spoons that come with powder detergent products have been used as spoons for measuring and removing granular or powdery materials from containers containing such materials.

[0003] There are also products that contain granular or powdered substances such as nutritional supplements in bags, and some products require the purchaser to take out small amounts of the granular or powdered substance at regular intervals, so a plastic or metal measuring spoon may be included to avoid the need for a measuring cup or other measuring device.

[0004] Plastic and metal measuring spoons are disposed of by incineration after use, but this creates a significant environmental burden, as they produce toxic gases during disposal.

[0005] Therefore, paper spoons can be used instead of plastic or metal spoons that are usually included with products.

[0006] For example, paper measuring spoons are shown in Patent Documents 1 and 2. The paper spoons shown in Patent Documents 1 and 2 are assembled from a single blank and include a scooping portion and a handle portion that is continuous with a portion of the scooping portion.

[0007] The scooping portion of the paper spoon is formed into a box shape with an open top, consisting of a bottom plate and four side plates, and the handle portion is formed by bending the handle top plate and handle reinforcing plate into a gate shape or by extending a handle piece from the side plate, with the front part of the handle reinforcing plate glued to the scooping portion, and when measuring, the handle portion is grasped as usual and powdered materials are scooped up with the scooping portion to measure them.

[0009] However, with the conventional paper measuring spoons mentioned above, it is not just a matter of assembling a single blank; adhesive is used to bond the plates that make up the scooping portion together, and the plates that make up the handle together, and the scooping portion and the handle portion are connected by bonding together at the required points, so there is a problem in that the production of conventional paper measuring spoons is complicated.

[0010] In view of the above circumstances, an object of the present invention is to provide a paper spoon that can be easily made from a single blank. [Means for solving the problem]

[0011] The present invention has been made in consideration of the above-mentioned problems, and provides a paper spoon made from a single blank and equipped with a handle and a scooping part, The handle portion is surrounded by the top plate and the first side plate and the second side plate, which are respectively folded toward the lower side of the top plate, by connecting the first side plate, the top plate, and the second side plate via a fold line, and the cross section of the handle portion is a triangular cylindrical shape, a slit is provided between the first side plate and the second side plate, the slit intersecting the direction along the bent portion; The scooping portion is formed by three surfaces: a scooping portion bottom plate extending forward in the spoon longitudinal direction from the slit portion; and a first side plate extension plate and a second side plate extension plate extending forward in the spoon longitudinal direction along the side edge of the scooping portion bottom plate and folding up the first side plate and the second side plate, and the cross section of the scooping portion is formed in a square trough shape. The top plate has a closure plate that is bent toward the scoop bottom plate and engaged with the slit, The above-mentioned problem is solved by providing a paper spoon characterized in that the closing plate closes the rear opening of the scooping part.

[0012] In the present invention, the scooping portion bottom plate and the first side plate extension plate are connected via a fold line, and the scooping portion bottom plate and the second side plate extension plate are connected via a fold line, Preferably, each of the fold lines extends through a notch formed at an end of the slit to the first side plate and the second side plate of the handle portion.

[0013] In addition, in the present invention, it is preferable that each side of the opening periphery of the scooping portion is linear, so that the contents placed in the scooping portion can be leveled along the opening periphery.

[0014] Furthermore, in the present invention, it is preferable that the fold line at the position connecting the first side panel, the top panel, and the second side panel in the handle portion, and the fold line at the position connecting the first side panel extension panel, the scooping portion bottom panel, and the second side panel extension panel in the scooping portion are mountain folds.

[0015] In addition, in the present invention, it is preferable that the area near the slit in the folded portion where the fold line between the first side plate and the second side plate in the handle portion is folded in a mountain fold, has a cross section in a direction intersecting the fold line that is curved outwardly convex.

[0016] In the present invention, the scooping portion bottom plate of the scooping portion is aligned along the spoon longitudinal direction where the handle portion and the scooping portion are continuous, It is preferable that the front of the scooping part in the longitudinal direction of the spoon is open, and the tip edge of the scooping part serves as an insertion end.

[0017] Furthermore, the present invention provides a paper spoon made of a single blank and having a handle and a scooping part, The handle portion is formed by connecting the first side plate, the reinforcing plate, the second side plate, and the top plate via a fold line, An adhesive tape is provided on one surface of the reinforcing plate, The handle portion is surrounded by the top plate and the first side plate and the second side plate, each of which is bent downward toward the top plate, and the top plate and the reinforcing plate are bonded together to form a cylindrical cross section of the handle portion. An insertion hole slit is formed in the bent portion between the first side plate and the second side plate, penetrating in the thickness direction, The scooping portion is formed by three surfaces: a scooping portion bottom plate extending forward in the spoon longitudinal direction from the insertion hole; and a first side plate and a second side plate extending forward in the spoon longitudinal direction and folded along the side edge of the scooping portion bottom plate, and the cross section of the scooping portion is formed in a square trough shape. The top plate has a closure plate that is bent toward the scoop bottom plate and engages with the insertion hole, The above-mentioned problem is solved by providing a paper spoon characterized in that the closing plate closes the rear opening of the scooping part. [Effects of the Invention]

[0018] According to the present invention, a paper spoon is provided which is made from a single blank and has a handle and a scooping portion, and the handle is formed by bending a first side panel, a top panel, and a second side panel which are connected together to form a cylindrical shape with a triangular cross section. The scooping portion is composed of a scooping portion bottom plate, and a first side plate extension plate and a second side plate extension plate that extend the first side plate and the second side plate forward in the longitudinal direction of the spoon, and the cross section of the scooping portion bottom plate and the folded first side plate extension plate and second side plate extension plate is shaped like a square gutter.

[0019] Since the cross section of the handle is triangular, the shape of the handle does not collapse and the handle does not twist when gripped, so the paper spoon can be handled by holding it with a certain amount of force. The scooping portion is formed by folding up the first side plate extension plate, which extends the first side plate of the handle portion in the longitudinal direction of the spoon, and the second side plate extension plate, which similarly extends the second side plate in the longitudinal direction of the spoon, on both sides of the scooping portion bottom plate. Therefore, there is no need to use adhesive when creating the scooping portion, and also, when connecting the handle portion and the scooping portion to form a single unit, no work of gluing them together is required, making it easy to create a paper spoon.

[0020] Furthermore, the scooping part also has a square trough-shaped cross section formed by the scooping part bottom plate and the first and second side plate extension plates that are continuous with the handle part, so the shape does not collapse, making it easy to collect granular or powdery materials using the scooping part.

[0021] In addition, there is a closure plate that closes the rear opening of the scooping portion, and this closure plate forms a wall that is arranged to intersect with the longitudinal direction of the spoon, which has the effect of preventing the handle portion from losing its shape in the circumferential direction and increasing its strength.

[0022] Furthermore, the first side plate and the first side plate extension plate are continuous plate members, and similarly the second side plate and the second side plate extension plate are continuous plate members, so the handle portion and the scooping portion are continuous and integrated in the longitudinal direction of the spoon, giving the entire paper spoon high strength and preventing bending between the handle portion and the scooping portion. Furthermore, the handle portion, which is integrated with the scoop portion, is tapered in the opposite direction to the scoop portion, which has the effect of making the handle portion easier to grip.

[0023] Furthermore, according to the present invention, the three-sided plate material of the scooping portion bottom plate, the first side plate extension plate, and the second side plate extension plate are connected via fold lines, and each of the fold lines is extended to the first and second side plates via a notch made at the end of a slit that is located at the rear edge position of the scooping portion bottom plate.

[0024] As described above, the fold lines at both sides of the bottom plate of the scooping portion are extended to the first side plate and the second side plate of the handle portion, so even if the scooping portion is continuous with the handle portion, which has a triangular cross section, the scooping portion can be easily folded into a square gutter shape.

[0025] Furthermore, according to the present invention, since the contents placed in the scooping portion can be leveled along the periphery of the opening, granular or powdery materials can be measured using the scooping portion.

[0026] Furthermore, according to the present invention, the fold line at the position connecting the first side panel, the top panel, and the second side panel in the handle portion, and the fold line at the position connecting the first side panel extension panel, the scooping portion bottom panel, and the second side panel extension panel in the scooping portion are mountain folds.

[0027] The fold lines between the plate materials in the handle portion and the fold lines between the plate materials in the scooping portion are both mountain folds, so the bending directions for the plate materials that make up the handle portion and the scooping portion are the same, resulting in a paper spoon that is easy to assemble.

[0028] Furthermore, according to the present invention, the area near the slit in the handle portion has a cross section in a direction intersecting the fold line that is curved and convex outward, so that the shape of the area near the slit is stable. Therefore, even if the fingertips of the hand gripping the handle are placed in the area near the slit, the handle can be gripped without having to be careful about deformation of the area near the slit.

[0029] Furthermore, according to the present invention, the bottom plate of the scooping part is aligned along the length of the spoon where the handle and scooping part are connected, the front of the scooping part in the length of the spoon is open, and the tip edge of the scooping part serves as the insertion end, so that the contents, such as granular or powdered materials, can be easily removed by simply inserting the scooping part by holding the handle into the removal opening of a bag containing the contents.

[0030] According to the present invention, a paper spoon can be assembled without using a separate adhesive tool, and therefore a paper spoon can be obtained that can be easily made from a single blank. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0032] First Embodiment Next, the present invention will be described in detail based on the embodiments shown in the drawings. Figure 1 shows a paper spoon 1 according to the first embodiment of the present invention. Paper spoon 1 is made by folding a single blank 2, and has a handle 3 and a scooping part 4 that are integrally formed and connected in the longitudinal direction A of the spoon.

[0033] 2 shows a blank 2 for obtaining a paper spoon 1. The blank 2 has a handle forming region 5 that will become the handle 3 and a scoop forming region 6 that will become the scoop 4.

[0034] (Handle forming area of ​​blank) The handle portion forming region 5 of the blank 2 is formed by connecting the top plate 7, first side plate 8, second side plate 9 and support plate 10 via fold lines 100, 101 and 102, and the support plate 10 is bent toward the second side plate 9 at the fold line 102 so that the support plate 10 is on the inside, and the second side plate 9 is also bent from the fold line 101 toward the first side plate 8 while bending in the same direction, and the first side plate 8 is further bent from the fold line 100 toward the top plate 7. Then, by hooking the side edge of the top plate 7 onto the bent portion formed at the position of the fold line 102 as described below, the top plate 7 and the support plate 10 are stacked together to form a cylindrical handle portion 3 with a triangular cross section.

[0035] (Tabletop) The top plate 7 has a width that gradually increases toward the front in the spoon longitudinal direction A when the handle portion 3 is assembled, and is trapezoidal in shape with a longer distance between the front and rear sides facing each other in the spoon longitudinal direction A.

[0036] (first side plate) The first side plate 8, which is connected to the top plate 7, is trapezoidal and is provided within the handle forming area 5. Like the top plate 7, the width of the plate gradually increases toward the front in the spoon longitudinal direction A, giving it an elongated shape in the spoon longitudinal direction A.

[0037] (Second side plate) The second side plate 9 is trapezoidal and is provided within the handle forming area 5. Like the first side plate 8, the width of the plate gradually increases toward the front in the spoon longitudinal direction A, giving it an elongated shape in the spoon longitudinal direction A.

[0038] The support plate 10 is also trapezoidal in shape, the same as the top plate 7, and has a shape that is long in the spoon longitudinal direction A, with the plate width gradually increasing toward the front in the spoon longitudinal direction A.

[0039] The top plate 7, the first side plate 8, the second side plate 9 and the support plate 10 are each trapezoidal in shape with the width gradually increasing towards the front in the spoon's longitudinal direction A, and as described above, the top plate 7 and the support plate 10 are overlapped by folding each of the fold lines 100, 101 and 102 in a mountain fold so that the support plate 10 faces inward and wraps around from the support plate 10 side, as described above.

[0040] The top plate 7 has a locking tongue 13 connected to the center of the side opposite to the crease line 100 via the crease line 103. Then, as described above, each of the fold lines 100, 101, and 102 in the handle portion forming area 5 is folded inward while making a mountain fold, and the top plate 7 and the support plate 10 are overlapped, and the locking tongue 13 is inserted into the insertion hole 12 cut and formed in the fold line 102 portion of the support plate 10 and the second side plate 9.

[0041] The handle portion 3 is formed with a triangular cylindrical cross section by inserting the locking tongue 13 into the insertion hole 12, and has a top plate 7, a first side edge 8 and a second side edge 9 arranged on three sides, forming a triangular shape with continuous plate material in the circumferential direction, thereby improving rigidity and preventing the shape from changing even when the handle portion 3 is held with a certain amount of force.

[0042] (Scooping area of ​​the blank) The scooping portion forming area 6 is provided with a first side plate extension plate 14, a scooping portion bottom plate 16, and a second side plate extension plate 15, and the first side plate extension plate 14 and the scooping portion bottom plate 16 are connected via a fold line 104, and the scooping portion bottom plate 16 and the second side plate extension plate 15 are connected via a fold line 105.

[0043] (First side plate extension plate) The first side plate extension plate 14 is a plate member that extends the first side plate 8 of the handle portion 3 forward in the spoon longitudinal direction A. As shown in Figure 2, which shows the shape of the blank 2, it has a roughly triangular shape that tapers from the first side plate 8 toward the front in the spoon's longitudinal direction A, and the pointed part is aligned with the front edge of the scooping part bottom plate 16.

[0044] (Second extension plate extension plate) The second side plate extension plate 15 is a plate member that extends the second side plate 9 of the handle portion 3 forward in the spoon longitudinal direction A, similar to the first side plate extension plate 14. The spoon has a generally triangular shape tapering from the second side plate 9 side toward the front in the spoon longitudinal direction A, and the pointed portion is aligned with the front edge of the scooping portion bottom plate 16.

[0045] The fold lines 104 and 105 are formed so as to open forward in the spoon longitudinal direction A. Furthermore, the two fold lines 104 and 105 each extend to enter inside the plate material of the first side plate 8 and the second side plate 9 of the handle portion forming region 5.

[0046] Furthermore, at the boundary between the handle portion forming area 5 and the scooping portion forming area 6, a slit 17 is provided that is perpendicular to the direction of the fold line 101 at a position that passes through the tip of the fold line 101 between the first side plate 8 and the second side plate 9, and that extends between the two fold lines 104 and 105.

[0047] (Scooping bottom plate) The scooping section bottom plate 16 is arranged between the first side plate extension plate 14 and the second side plate extension plate 15, and has a trapezoidal shape with the position where the pointed portions of the first side plate extension plate 14 and the second side plate extension plate 15 are aligned as the front edge and the position of the slit 17 as the rear edge.

[0048] In addition, each end of the slit 17 has a notch 18 that overlaps with the fold lines 104 and 105, and the end of the slit 17 is formed in such a way that a T-shaped cut is made by the slit 17 and the notch 18.

[0049] (Scooping part) At the same time as forming the handle portion 3, the first side plate extension plate 14 and the second side plate extension plate 15 are folded toward the scooping portion bottom plate 16 at the positions of the fold lines 104 and 105, and the handle portion 3 is made cylindrical as described above, thereby forming the scooping portion 4 with the first side plate extension plate 14 and the second side plate extension plate 15 standing upright.

[0050] As shown in Figure 3, which shows the paper spoon 1 viewed from the scooping section 4 side, the scooping section 4 is bent upward (in the direction penetrating the scooping section bottom plate 16) from the bending portion where the fold lines 104 and 105 are located, and the first side plate extension plate 14, the scooping section bottom plate 16, and the second side plate extension plate 15 form a gate-shaped rectangular gutter in cross section.

[0051] (closing plate) A closure plate 19 is connected to the front edge (the edge on the scooping portion 4 side) of the top plate 7 of the handle portion 3 via a fold line 106. The closure plate 19 is folded down and is located at the boundary between the handle portion 3 and the scooping portion 4. The closure plate 19 is formed in a trapezoidal shape corresponding to the shape of the rear opening of the scooping portion 4, and closes the rear opening of the scooping portion 4.

[0052] The closure plate 19 has a locking tongue 20 on the edge on the scooping part bottom plate 16 side, and by inserting the locking tongue 20 into the slit 17, the closure plate 19 is fixed to the boundary between the handle part 3 and the scooping part 4.

[0053] As shown in Figure 5, which shows the state of paper spoon 1 as seen from the side, closure plate 19 is inclined, and the position of the edge with locking tongue 20 is forward in the spoon's longitudinal direction A from the position of the edge that forms the bent portion on the top plate 7 side. Since closure plate 19 is inclined downward toward the front in the spoon's longitudinal direction A, it is prevented from being folded inward by mistake into the cylindrical shape of handle portion 3 when folding closure plate 19.

[0054] Furthermore, flaps 21 are connected to each side of the closure plate 19 via fold lines 107 and 108, and are folded forward in the spoon longitudinal direction A so as to contact the inner surfaces of the first side plate extension plate 14 and the second side plate extension plate 15.

[0055] Each of the flaps 21 overlaps and contacts the first side plate extension plate 14 and the second side plate extension plate 15, preventing gaps from occurring between the closure plate 19 and the first side plate extension plate 14 and the second side plate extension plate 15, and preventing the granular or powdered material from entering the inside of the cylindrical shape of the handle portion 3 from the scooping portion 4 when the granular or powdered material is taken out with the paper spoon 1.

[0056] Between the first side plate 8 and the second side plate 9 of the handle portion 3, there is a folded portion 22 that is folded in a mountain shape at the position of the folding line 101. In the slit vicinity region 23 in the folded portion 22, which reaches the position of the slit 17, the cross section of the first side plate 8 and the second side plate 9 in the direction intersecting the fold line 101 is formed as a curved portion 24, with the cross section being an outwardly convex curved shape, as shown in Figure 4, which shows the cross section of the boundary between the handle portion 3 and the scooping portion 4.

[0057] Since the curved portion 24 is formed in the slit vicinity region 23 of the grip portion 3, the shape of the slit vicinity region 23 is stable even if the slit 17 exists. Therefore, even if the fingertips of the hand gripping the handle 3 are hooked on the slit vicinity region 23, the slit vicinity region 23 will not deform, and the handle 3 can be held with a certain amount of force applied.

[0058] As shown in Figure 1, which shows paper spoon 1 viewed from diagonally above, and Figure 5, which shows paper spoon 1 viewed from the side, each edge around the opening of scooping section 4 (the bent portion between top plate 7 and closure plate 19, the upper edge of first side plate extension plate 14, the upper edge of second side plate extension plate 15, and the front edge of scooping section bottom plate 16) is formed in a straight line.

[0059] Since each side constituting the periphery of the opening of the scooping part 4 is linear in this way, it is possible to hold the handle part 3 and scoop up the stored items into the scooping part 4, and then perform a leveling operation along the periphery of the opening, and the removed stored items can be easily weighed.

[0060] In addition, the scooping portion bottom plate 16 of the scooping portion 4 is aligned along the spoon longitudinal direction A where the handle portion 3 and the scooping portion 4 are continuous, and the front and top of the scooping portion 4 in the spoon longitudinal direction A are open.

[0061] Then, by holding the handle 3 and inserting the paper spoon 1 toward the stored item consisting of granular or powdery material stored in a bag or the like, the front edge of the scooping part bottom plate 16, which is one side around the opening of the scooping part 4, becomes the insertion end, allowing the scooping part 4 to be smoothly inserted by piercing it into the stored item, and the stored item can be placed into the scooping part 4 with a simple operation.

[0062] In contrast to the paper spoon 1 of this embodiment, conventional paper measuring spoons have a box-shaped scooping section with only the top surface open, so when removing contents from a container with a narrow insertion opening, the entire measuring spoon must be rotated significantly around the axis of the handle to insert the contents into the box-shaped scooping section.

[0063] Therefore, conventional paper measuring spoons have the problem that it is time-consuming to scoop out the contents while properly placing them in the scooping part, but paper spoon 1 has the advantage that the contents can be easily removed by holding handle part 3 and piercing scooping part 4 into the contents.

[0064] In the paper spoon 1 in the above embodiment, the slit 17 is placed at a position that passes through the tip of the fold line 101, but the present invention is not limited to the above embodiment, and it is possible to place the slit 17 at a position that intersects with the direction along the bent portion formed by the fold line 101.

[0065] Second Embodiment 7 is a diagram showing a paper spoon 31 according to the second embodiment of the present invention. The paper spoon 31 is made by folding a single blank 32, and has a handle 33 and a scooping part 34 that are integrally formed and connected in the longitudinal direction B of the paper spoon 31.

[0066] 8 is a diagram showing a blank 32 for forming a paper spoon 31. The blank 32 is configured to include a handle forming region 35 that will become the handle 33, and a scoop forming region 36 that will become the scoop 34.

[0067] (Handle forming area) In the handle forming region 35, the top plate 37, the first side plate 38, the second side plate 39, the first side plate extension plate 44, the second side plate extension plate 45, and the reinforcing plate 60 are connected via fold lines 200, 201, 202, 209, and 210.

[0068] The first side panel 38 and the second side panel 39 are bent so as to approach each other along the crease 201, and the second side panel extension panel 45 is bent toward the second side panel 39 at the crease 202 while bending in the same direction as the second side panel 39. Furthermore, the top panel 37 is bent toward the second side panel 39 at the crease 209.

[0069] Next, the first side panel extension 44 is folded toward the first side panel 38 at the fold line 200 while bending in the same direction as the first side panel 38. Furthermore, the reinforcing panel 60 is folded toward the first side panel extension 44 at the fold line 210. At this time, the release paper of the adhesive tape 61 of the reinforcing panel 60 is removed, and the surface of the adhesive tape 61 is pressed against the top panel 37, thereby adhering and fixing the reinforcing panel 60 to the top panel 37.

[0070] Next, the closure plate 49 is folded along the crease 206, and the locking tongues 50 are inserted and locked into the insertion holes 47. The flaps 51 are then folded away from each other and spread out so that they contact the first side plate 38 and the second side plate 39, respectively, completing the assembly of the paper spoon 31.

[0071] (first side plate) The first side plate 38 is connected to the second side plate 39 via a fold line 201. The first side plate 38 has a side 38a parallel to the longitudinal direction B that forms the fold line 201, a side 38b parallel to the side 38a that forms the fold line 200, a side 38c that extends obliquely from one end of the side 38a toward the side 38b and bends, then extends in a direction perpendicular to the longitudinal direction B and connects to the side 38b, a side 38d that is connected to the other end of the side 38a and forms a substantially arc shape, a side 38e that is connected to the side 38d and extends obliquely toward the side 38b, and forms the fold line 204, a side 38f that has one end connected to the side 38e and extends in a direction perpendicular to the longitudinal direction B and then bends, and a side 38g that has one end connected to the side 38b and the other end connected to the side 38f.

[0072] (Second side plate) The second side plate 39 is formed symmetrically with the first side plate 38 with respect to the fold line 201. To avoid duplication, similar to the first side wall 38, the sides 39a to 39g are indicated by reference numerals and the description thereof will be omitted.

[0073] (First side plate extension plate) The first side panel extension plate 44 is connected to the first side panel 38 via a fold line 200 and is formed into a rectangular shape. The first side panel extension plate 44 has a side 38b, a side 44a having one end connected to one end of the side 38b and extending in a direction horizontal to the longitudinal direction B, a side 44b having one end connected to the other end of the side 44a and extending at an angle to the longitudinal direction B, and a side 44c having one end connected to the other end of the side 44b and the other end connected to the other end of the side 38b.

[0074] (Second side plate extension plate) The second side panel extension plate 45 is connected to the second side panel 39 via the fold line 202 and is formed into a rectangular shape. The second side panel extension plate 45 has a side 39b, a side 45a having one end connected to one end of the side 39b and extending in a direction horizontal to the longitudinal direction B, a side 45b having one end connected to the other end of the side 45a and extending at an angle to the longitudinal direction B, and a side 45c having one end connected to the other end of the side 45b and the other end connected to the other end of the side 39b.

[0075] (Scooping bottom plate) The scooping portion bottom plate 36 has a trapezoidal shape with its rear side facing an insertion hole 47 (described later) located on the rear side in the longitudinal direction B. In the folding lines 204 and 205 forming the two oblique sides of the scooping portion bottom plate 36, notches 48 are formed so as to overlap with the positions where they connect with the insertion hole 47.

[0076] (Tabletop) The top plate 37 is connected to the second side plate extension plate 45 via a fold line 209, and is formed so that the plate width gradually increases toward the front B1 in the longitudinal direction B when the handle portion 33 is assembled, and is formed into a trapezoidal shape with a longer distance between the opposing front and rear edges in the longitudinal direction B.

[0077] (closing plate) A closure plate 49 is connected to the front side of the top plate 37 in the longitudinal direction B via a fold line 206 extending in a direction perpendicular to the longitudinal direction B. The closure plate 49 is formed in a trapezoidal shape with the fold line 206 as its base, and a convex locking tongue 50 that protrudes forward in the longitudinal direction B is formed at the upper base portion. Approximately square flaps 51 are connected to the fold lines 207, 208 that form a pair of oblique sides of the closure plate 49, respectively.

[0078] (reinforcement plate) A reinforcing plate 60 is connected to the first side panel extension plate 44 on the side opposite the first side panel 38 via a fold line 210. The reinforcing plate 60 has a side 44b, a side 60a connected to one end of the side 44b and extending at an angle toward the longitudinal direction B with respect to a direction perpendicular to the longitudinal direction B, a side 60b connected to the side 60a at one end and extending along the longitudinal direction B, and a side 60c connected to the other end of the side 60b at one end and the other end of the side 44b at the other end. The side 60b, the side 38b, and the side 39b are formed substantially parallel to one another. A strip-shaped adhesive tape 61 is provided on the surface of the reinforcing plate 60 so as to extend along the longitudinal direction B. The adhesive tape 61 is realized, for example, by double-sided tape, and has a release paper attached thereto at the time of shipment. The adhesive tape 61 may be applied by a so-called sack application using a sack application machine, or glue may be applied to the area of ​​the adhesive tape 61.

[0079] 9 is a front view of paper spoon 31, FIG. 10 is a side view of paper spoon 31, FIG. 11 is a view of paper spoon 31 taken along cross section line DD in FIG. 10, and FIG. 12 is a bottom view of paper spoon 31.

[0080] (Scooping part forming area) The scooping portion forming area 6 is constituted by the front portion of the first side plate 38, the scooping portion bottom plate 46, and the front portion of the second side plate 39. The front portion of the first side plate 38 and the scooping portion bottom plate 16 are connected via a fold line 204. The scooping portion bottom plate 16 and the front portion of the second side plate 39 are connected via a fold line 205.

[0081] Folding line 204 and folding line 205 are formed to widen and move away from each other as they move forward in longitudinal direction B. An insertion hole 47 is formed at the boundary between handle portion forming region 35 and scooping portion forming region 36, on the rear side in longitudinal direction B of scooping portion bottom plate 16, at a distance between the rear end of scooping portion bottom plate 16 in longitudinal direction B and the front end of folding line 201 in longitudinal direction B. Insertion hole 47 is a generally triangular hole that convex toward the rear in longitudinal direction B.

[0082] (Scooping part) At the same time as forming the handle portion 33, the first side plate 38 and the second side plate 39 are bent toward the scooping portion bottom plate 46 at the fold lines 204, 205 to form the handle portion 33 into a cylindrical shape, whereby the front portions of the first side plate 38 and the second side plate 39 are raised upright, thereby forming the scooping portion 34.

[0083] As shown in Figure 9, the scooping portion 34 is bent upward (in the direction penetrating the scooping portion bottom plate 46) at the position of the fold lines 204, 205, and the tip portion of the first side plate extension 44, the scooping portion bottom plate 46, and the tip portion of the second side plate 45 form a gate-shaped, angular gutter-like cross section.

[0084] The closure plate 49 is fixed to the boundary between the handle portion 33 and the scoop portion 34 by inserting the locking tongue 50 into the insertion hole 47. The closure plate 39 is folded down and positioned at the boundary between the handle portion 33 and the scoop portion 34. The closure plate 49 is formed in a roughly trapezoidal shape corresponding to the shape of the rear opening of the scoop portion 34, and closes the rear opening of the scoop portion 34.

[0085] 10, the closure plate 49 is provided at an incline, and the position of the edge having the locking tongue 50 is forward in the longitudinal direction B from the position of the edge that forms the bent portion on the top plate 37 side. Since the closure plate 49 is inclined downward in the longitudinal direction B, it is possible to prevent the closure plate 49 from being inadvertently folded inside the cylindrical shape of the handle portion 33 when folding it.

[0086] Furthermore, flaps 51 are connected to each side of the closure plate 39 via fold lines 207 and 208, and are folded forward in the longitudinal direction B so as to contact the inner surfaces of the first side plate 44 and the second side plate 45.

[0087] The flaps 51 are provided in contact with and overlap the first side plate 44 and the second side plate 45, respectively, preventing gaps from forming between the closure plate 49 and the first side plate 44 and the second side plate 45. This prevents the granular or powdered material from entering the inside of the cylindrical shape of the handle portion 33 from the scooping portion 34 when the granular or powdered material is taken out with the paper spoon 30.

[0088] 9, the locking tongue 50 formed at the tip of the closure plate 49 is inserted into the insertion hole 47. As a result, the locking tongue 50 is locked in a state where it protrudes downward from the insertion hole 47. Therefore, the closure plate 49 can be held in an inclined state, and the flap 51 can be reliably positioned between the closure plate 49 and the first side plate 44 and the second side plate 45.

[0089] As shown in Figure 10, each side around the opening of the scooping portion 34 (side 38g, side 44c, side 39g, side 45c, the bottom side of the closure plate 49 (fold line 206), and the front side of the scooping portion bottom plate 46) is formed in a straight line.

[0090] Since each side constituting the periphery of the opening of the scooping part 34 is linear in this way, it is possible to scoop up the stored items into the scooping part 34 by holding the handle part 33, and then to perform a leveling operation along the periphery of the opening, and the stored items taken out can be easily weighed.

[0091] Furthermore, the scooping portion bottom plate 46 of the scooping portion 34 is aligned along the longitudinal direction B in which the handle portion 33 and the scooping portion 34 are continuous, and the front and top of the scooping portion 34 in the longitudinal direction B are open.

[0092] Therefore, by holding the handle 33 and inserting the paper spoon 31 toward the stored item consisting of granular or powdered material stored in a bag or the like, the front edge of the scooping part bottom plate 46, which is one side around the opening of the scooping part 34, becomes the insertion end, allowing the scooping part 34 to be smoothly inserted as if piercing the stored item, and the stored item can be placed into the scooping part 34 with a simple operation.

[0093] The paper spoon 31 has a reinforcing plate 60, which includes a side 60b parallel to the longitudinal direction B. By adopting this configuration, a blank 32 can be cut from paper stock and transported below a roller around which adhesive tape 61 is wound, with the side 60b aligned with the wall of the factory line. Furthermore, in the process of applying the adhesive tape 61, the side 60b can be used as a guide to easily apply the adhesive tape 61 to the blank 32 along the side 60b, thereby facilitating the process of forming the adhesive tape 61. Furthermore, because the reinforcing plate 60 has the side 60b parallel to the longitudinal direction B, guiding the blank 32 along the longitudinal direction B allows glue to be applied automatically using a sack applicator. This allows for the realization of a paper spoon 31 that is highly suitable for mass production.

[0094] According to this embodiment, paper spoon 31 can be assembled in the following order: valley fold at crease 201, valley fold at crease 202, valley fold at crease 209, valley fold at crease 200, valley fold at crease 210, fixing top plate 37 and reinforcing plate 60 with adhesive tape 61, valley fold at crease 206, inserting locking tongue 50 into insertion hole 47, and unfolding flap 51. Therefore, paper spoon 31 can be assembled without using a separate adhesive tool, and paper spoon 31 can be easily produced from a single blank 32.

[0095] According to this embodiment, the paper spoon 31 can be shipped in a state in which the top plate 37 and the reinforcing plate 60 are secured with adhesive tape 61 after making a valley fold at crease line 201, a valley fold at crease line 202, a valley fold at crease line 209, a valley fold at crease line 200, and a valley fold at crease line 210, and the user can quickly assemble the paper spoon 31 with a one-touch operation of making a valley fold at crease line 206, inserting the locking tab 50 into the insertion hole 47, and unfolding the flap 51. Furthermore, in this way, even in a sealed state, the blank 32 can be kept flat and space-saving, so the paper spoon 31 can be stored together with a variety of products.

[0096] In the above description, a valley fold refers to folding in a direction in which the inner surfaces approach each other with respect to each fold line, based on blank 2 shown in Figure 2 and blank 32 shown in Figure 8. Conversely, a mountain fold refers to folding in a direction in which the outer surfaces approach each other. [Explanation of symbols]
