Description

  The present invention relates to an improvement of a paper container to which a handle body can be attached.

  As shown in FIGS. 11 to 13, there is a paper container C ′ having a structure to which a handle 700 can be attached. The paper container C ′ includes (1) a quadrangular bottom surface portion 200, (2) a first side surface portion 300 continuous to the bottom surface portion 2 with a side extending in the horizontal direction of the bottom surface portion 2 as a horizontal ruled line 300a, and (3) A side surface extending in the front-rear direction of the bottom surface portion 2 is defined as a horizontal ruled line 400a, and a second side surface portion 400 connected to the bottom surface portion 2 and (4) a first vertical ruled line 500a extending radially from the corner of the bottom surface portion 2. The second side surface portion 400 is connected to one side surface portion 300 through a second vertical ruled line 500b extending radially from the corner of the bottom surface portion 2 so as to form a fixed angle with the first vertical ruled line 500a. It is formed so as to be provided with a corner piece portion 500 that is between the first vertical ruled line 500a and the second vertical ruled line 500b and is folded in half by a third vertical ruled line 500c extending radially from the corner of the bottom face part 2. Than the finished paperboard (5) The surface portion of the corner piece 500 surrounded by the first vertical ruled line 500a and the third vertical ruled line 500c faces the outer surface of the first side surface 300, and the second vertical ruled line 500b is the paper container C ′. Are folded along the ruled lines 300a, 400a, 500a, 500b, and 500c so as to form the corners of the first side part 300, and the terminal part on the third vertical ruled line 500c of the corner piece part 500 that is folded from the right side of the first side part 300 And a terminal part on the third vertical ruled line 500c of the corner piece part 500 folded from the left side are overlapped and fastened to form a container shape. (6) The overlapping portion is used as a mounting portion 600 that can be hooked from below 700a of the handle 700 having hook-like portions 700a at both ends.

  However, in the paper container C ′, the distance from the corner of the bottom surface part 2 in the corner piece part 500 to the outer edge of the paperboard in the corner piece part 500 is the depth of the paper container C ′, that is, the side part. Therefore, when the paper container C ′ becomes shallower than a certain level, the end portions of the left and right corner pieces 500 folded as described above cannot be overlapped with each other. (FIG. 14) That is, the attaching part 600 of the hook-like part 700a cannot be formed. In this case, the handle 700 can be attached if a hole for hooking the hook-like portion 700a is formed in the first side surface portion 300, but this is not suitable for the paper container C 'having a watertight structure.

  The main problem to be solved by the present invention is that this kind of paper container can be appropriately fitted with the handle mounting portion without being affected by the depth dimension and without reducing the water tightness thereof. The point is that it can be formed.

In order to achieve the above object, according to the present invention, from the first viewpoint, a paper container is formed with a substantially rectangular bottom surface,
A first side surface portion that continues to the bottom surface portion as a horizontal ruled line that extends in the left-right direction of the bottom surface portion,
A second side surface portion connected to the bottom surface portion as a horizontal ruled line extending in the front-rear direction of the bottom surface portion,
The first vertical ruled line extending in the radial direction from the corner of the bottom surface portion is connected to the first side surface portion, and the fixed angle is formed between the first vertical ruled line and the radial direction from the corner of the bottom surface portion. A corner piece that is continuous with the second side surface portion via the second vertical ruled line and is folded in half by a third vertical ruled line that extends between the first vertical ruled line and the second vertical ruled line and extends radially from the corner of the bottom surface part. A paperboard formed to have a portion,
A surface portion surrounded by the first vertical ruled line and the third vertical ruled line in the corner piece portion faces the outer surface of the first side surface portion, and the second vertical ruled line is along each ruled line so as to form a corner of the paper container. At the same time as folding, the terminal part on the third vertical ruled line of the corner piece part folded from the right side of the first side part and the terminal part on the third vertical ruled line of the corner piece part folded from the left side are overlapped and fixed. A paper container having a hook-like attachment portion that can be hooked from below on the handle body provided with hook-like portions at both ends of the overlapping portion.
A vertical cut line formed by a predetermined dimension from the outer edge of the paperboard toward the corner along a virtual vertical line extending radially from the corner of the bottom surface between the first vertical ruled line and the third vertical ruled line. The horizontal cutting line formed between the vertical cutting line and the first vertical ruled line is provided along a virtual horizontal straight line that intersects the virtual vertical straight line.

In order to achieve the above object, according to the present invention, from the second viewpoint, the paper container is substantially a quadrangular bottom portion,
A first side surface portion that continues to the bottom surface portion as a horizontal ruled line that extends in the left-right direction of the bottom surface portion,
A second side surface portion connected to the bottom surface portion as a horizontal ruled line extending in the front-rear direction of the bottom surface portion,
The first vertical ruled line extending in the radial direction from the corner of the bottom surface portion is connected to the first side surface portion, and the fixed angle is formed between the first vertical ruled line and the radial direction from the corner of the bottom surface portion. A corner piece that is continuous with the second side surface portion via the second vertical ruled line and is folded in half by a third vertical ruled line that extends between the first vertical ruled line and the second vertical ruled line and extends radially from the corner of the bottom surface part. A paperboard formed to have a portion,
A surface portion surrounded by the first vertical ruled line and the third vertical ruled line in the corner piece portion faces the outer surface of the first side surface portion, and the second vertical ruled line is along each ruled line so as to form a corner of the paper container. At the same time as folding, the terminal part on the third vertical ruled line of the corner piece part folded from the right side of the first side part and the terminal part on the third vertical ruled line of the corner piece part folded from the left side are overlapped and fixed. A paper container having a hook-like attachment portion that can be hooked from below on the handle body provided with hook-like portions at both ends of the overlapping portion.
Between the first vertical ruled line and the third vertical ruled line, it extends between the outer edge of the paperboard and the first vertical ruled line along a virtual horizontal straight line that intersects a virtual vertical straight line extending radially from the corner of the bottom surface portion. It was supposed to be provided with a transverse line formed.

  The longer the length of the horizontal cut line, that is, the distance between the first vertical ruled line and the virtual vertical straight line, the more the end portion of the corner piece folded as described above is folded from the right side. If it is a corner piece portion that is folded, it is located on the left side, and if it is a corner piece portion that is folded from the left side, it is located on the right side. Thereby, the said attachment part can be formed appropriately, without being influenced by the depth of a paper container. In other words, the length of the horizontal cut line is adjusted according to the distance from the corner of the bottom surface portion to the outer edge of the paperboard at the corner piece portion based on the depth of the constructed paper container, thereby being folded outside the first side surface portion. In addition, it is possible to easily create a state in which the terminal portions of the left and right corner pieces overlap each other so as to be fixed.

  The outer edge of the paperboard is shaped to form a semicircular arc with the top located at the location located on the third vertical ruled line in the center of the corner piece, and the left and right corner pieces that became the attachment portions If the semicircular arc-shaped outer edge guides the claw portion formed inside the open end of the hook-like portion of the handle body, the handle body attached to the paper container can be rotated in the left-right direction. It can be done smoothly.

  Further, the corner piece portion is connected to the surface portion surrounded by the second vertical ruled line and the third vertical ruled line on the third vertical ruled line when the corner piece part is folded in two, and forward from the folded portion of the corner piece part. If a notch is formed so as to form a pressing piece located directly under the mounting portion, the side opposite to the open end of the hook-like portion of the handle attached to the mounting portion as described above is placed on the pressing piece. Thus, the attached state can be stably maintained by supporting from below.

  According to the present invention, it is possible to appropriately form the attachment portion of the handle body without being affected by the depth of the paper container and in a mode in which the water tightness is not lowered.

  A typical embodiment of the present invention will be described below with reference to FIGS. The paper container C according to this embodiment is a container generated from the paperboard 1 and has a water-tight structure and includes an attachment portion 6 for the handle body 9.

  Specifically, the paper container C is generated from the paperboard 1 punched by punching. In the punching process, the paper board 1 is provided with ruled lines 3 a, 4 a, 5 a, 5 b, 5 c (streaks attached by muscle pressing) and cut lines 7, 8 (cuts), which will be described later. By folding the paperboard 1 along the ruled lines and fastening described later (fastening of the terminal portions of the left and right corner pieces), a paper container C having an upper surface opening is generated.

  More specifically, the paper container C is generated from the paperboard 1 having one bottom surface portion 2, four side surface portions 3 ... 4, and four corner piece portions 5 ... 5.

  The bottom surface portion 2 is substantially rectangular. Each side 2a, 2b of the bottom part 2 may have a slight curvature. In the illustrated example, the bottom surface portion 2 has a rectangular shape.

  The four side surface portions 3... 4 include two first side surface portions 3 and 3 and two second side surface portions 4 and 4. The first side surface portion 3 continues to the bottom surface portion 2 with the side 2a extending in the left-right direction of the bottom surface portion 2 as a horizontal ruled line 3a. The second side surface portion 4 is connected to the bottom surface portion 2 with the side 2b extending in the front-rear direction of the bottom surface portion 2 as a horizontal ruled line 4a. In the illustrated example, the side 2 a extending in the left-right direction of the bottom surface part 2 is a side on the width side of the bottom surface part 2, and the side 2 b extending in the front-rear direction of the bottom surface part 2 is the side on the length side of the bottom surface part 2. It has become.

  The corner piece part 5 is connected to the first side face part 3 via a first vertical ruled line 5a extending in a radial direction from the corner 2c of the bottom face part 2, and forms a fixed angle with the first vertical ruled line 5a. As described above, the bottom surface portion is connected to the second side surface portion 4 via the second vertical ruled line 5b extending in the radial direction from the corner 2c of the bottom surface portion 2 and between the first vertical ruled line 5a and the second vertical ruled line 5b. 2 is folded in half by a third vertical ruled line 5c extending radially from the corner 2c.

  In the illustrated example, the fixed angle formed by the first vertical ruled line 5a and the second vertical ruled line 5b is an acute angle slightly smaller than a right angle.

  In this embodiment, the surface portion 5d surrounded by the first vertical ruled line 5a and the third vertical ruled line 5c in the corner piece portion 5 faces the outer surface 3b of the first side surface portion 3, and the first Folding is performed along the ruled lines 3a, 4a, 5a, 5b, and 5c so that the two vertical ruled lines 5b form the corners Ca of the paper container C, and the second corner ruled part 5 is folded from the right side of the first side face part 3. The terminal 5e on the three vertical ruled lines 5c and the terminal part 5e on the third vertical ruled line 5c of the corner piece 5 folded from the left side are overlapped and fixed to constitute the paper container C. Such fastening is typically done by gluing.

  In addition, the overlapping portion of the left and right corner pieces 5 and 5 in the paper container C becomes an attachment portion 6 that can hook the hook-like portion 9a of the handle body 9 having hook-like portions 9a at both ends from below. ing.

  In the illustrated example, the handle body 9 is formed by forming hook-shaped portions 9a at both ends of a thin strip-shaped body 9c. Then, one hook-like portion 9a of the handle body 9 is hooked on the attachment portion 6 on the first side surface portion 3 side of the paper container C configured as described above, and the other hook of the handle body 9 is hooked. The handle 9a is hooked to the attachment portion 6 on the other first side surface portion 3 side of the paper container C configured as described above, so that the handle C is held between the front and back first side surface portions 3 with respect to the paper container C. A body 9 is provided.

  In this embodiment, the hook-like portion 9a of the handle body 9 has one end integrally connected to the end of the band-like body 9c via the connecting portion 9d and is directed toward the center side of the band-like body 9c. It is comprised by the hook component piece 9e extended. A claw portion 9f is formed at the other end of the hook constituting piece 9e and facing the strip 9c, and the gap between the claw 9f and the strip 9c is smaller than the thickness of the attachment portion 6. . That is, the handle body 9 includes a claw portion 9f inside the open end 9b of the hook-shaped portion 9a.

  In this embodiment, after the end portion of the handle body 9 is inserted between the first side surface portion 3 and the attachment portion 6 from above, this end portion is moved upward to form the hook-shaped portion 9a. The hook portion 9e is positioned on the outer surface side 6a of the mounting portion 6 and the end portion of the strip 9c is positioned on the inner surface side 6b of the mounting portion 6 so that the mounting portion 6 is interposed between the open end 9b and the both ends. When inserted, the hook component piece 9e is elastically deformed so as to widen the gap between the connecting member 9d and the band-like body 9c, and the insertion is allowed. After that, when the nail portion 9f is inserted to the position where it is located on the upper edge 6c of the attachment portion 6, the hook component piece 9e is elastically restored so that the nail portion 9f is caught by the upper edge 6c. It has become. (FIGS. 4 and 5) The handle body 9 is typically made of a synthetic resin.

  Further, the paper container C according to this embodiment includes the paperboard 1 along a virtual vertical straight line x extending radially from the corner 2c of the bottom surface portion 2 between the first vertical ruled line 5a and the third vertical ruled line 5c. A vertical cutting line 7 formed by a predetermined size from the outer edge of the vertical cutting line 7 toward the corner 2c, and an end 7a of the vertical cutting line 7 and a first vertical ruled line along a virtual horizontal line y intersecting the virtual vertical line x And a transverse line 8 formed between 5a and 5a. A range located between the vertical cutting line 7 and the corner 2c of the bottom surface portion 2 is a substantially water-tight depth in the paper container C.

  The longer the length of the horizontal cutting line 8, that is, the distance between the first vertical ruled line 5a and the vertical cutting line 7, the more the terminal part 5e of the corner piece part 5 folded as described above has If the corner piece portion 5 is folded from the right side, it is located on the left side, and if it is the corner piece portion 5 folded from the left side, it is located on the right side. Accordingly, the attachment portion 6 can be appropriately formed without being affected by the depth of the paper container C. That is, the first side surface is adjusted by adjusting the length of the transverse line 8 according to the distance from the corner 2c of the bottom surface portion 2 to the outer edge of the paperboard 1 in the corner piece portion 5 based on the depth of the constructed paper container C. It is possible to easily create a state in which the terminal portions 5e of the left and right corner piece portions 5 and 5 folded on the outside of the portion 3 are overlapped so as to be fastened. Specifically, in the example of FIGS. 6 to 8 in which the depth of the paper container C is shallower than the example shown in FIGS. 1 to 5, the transverse line 8 is made longer than the example shown in FIGS. .

  Further, in this embodiment, the outer edge of the paperboard 1 is shaped so as to form a semicircular arc shape with the top located at a position located on the third vertical ruled line 5c in the center of the corner piece portion 5. The left and right corner piece portions 5 that become the attachment portions 6 serve as guides for the claw portions 9f formed inside the open ends 9b of the hook-like portions 9a of the handle body 9 by the semicircular outer edges 5f. I am doing so. Thereby, in this embodiment, the handle body 9 attached to the paper container C is smoothly rotated in the left-right direction.

  In the example shown in FIGS. 9 and 10, a virtual vertical line extending in the radial direction from the corner 2 c of the bottom surface portion 2 between the first vertical ruled line 5 a and the third vertical ruled line 5 c without forming the vertical cut line 7. Only a horizontal cut line 8 is formed between the outer edge of the paperboard 1 and the first vertical ruled line 5a along a virtual horizontal straight line y that intersects the straight line x. Further, in this example, the recesses 5i are respectively formed at symmetrical positions across the third vertical ruled line 5c in the semicircular arc-shaped portion of the corner piece portion 5. If such a recess 5i is formed, the recess 5i can be positioned at a position in the middle of the mounting portion 6 in the left-right direction. Therefore, the band-like body 9c constituting the handle body 9 extends in the vertical direction from the middle position in the left-right direction of the paper container C by storing the claw portion 9f of the hook-like portion 9a of the handle body 9 in the recess 5i. It becomes possible to maintain the posture of the handle body 9 that has been made. Thereby, the paper container C can be prevented from being inclined as much as possible when the handle body 9 is gripped and the paper container C is held down.

  In this embodiment, the corner piece 5 has a surface portion surrounded by the second vertical ruled line 5b and the third vertical ruled line 5c on the third vertical ruled line 5c when the corner piece 5 is folded in half. A notch 5h is formed so as to protrude forward from the folded portion of the corner piece portion 5 and form a pressing piece 5g located immediately below the attachment portion 6. In the illustrated example, the notch 5h has a semicircular shape in which the third vertical ruled line 5c side is curved inside, and the upper end of the notch 5h and the lower end of the notch 5h are in contact with the third vertical ruled line 5c, respectively. The corner piece 5 is formed on the surface 5d surrounded by the first vertical ruled line 5a and the third vertical ruled line 5c. Thereby, in this embodiment, the side opposite to the open end of the hook-like portion 9a of the handle body 9 attached to the attachment portion 6 as described above is supported from below by the pressing piece 5g. The mounting state is stably maintained.
