Description

  The present invention relates to a paper tray-like container, and more particularly to a paper tray-like container formed by connecting a bottom plate and a peripheral side plate thereof with paper.

  For example, in Japanese Patent Application Laid-Open No. 2005-350133, a container main body including a rectangular bottom plate and four side plates connected to each side thereof, and a box-shaped lid body that can be held in a state in which the four side plates of the container main body are erected. The container main body is provided with a mark for cake cutting on at least one pair of opposing side plates among the four main side plates of the container, and the assembled container main body can be used as a molding frame by being loaded into the mold at the time of cake molding. After the cake is formed, it can be used as a distribution box as it is by putting a box-shaped lid on the container main body. Furthermore, when the consumer eats the cake, it can be divided equally by simply unfolding the container-side four-side plate. A cake container is disclosed which can be used as a cutting board having marks for dividing.

  Such a container can be used as a cutting board by expanding the four side plates connected to each side of the bottom plate to the outside, and is housed inside by cutting with a knife using the marks provided on the side plates. The cake can be cut at a predetermined interval, which is convenient.

  However, such a container must separate adjacent side plates and open the side plates outward. That is, there is a drawback that the cake cannot be cut with a knife while the assembled container remains in a box.

  Japanese Laid-Open Patent Publication No. 2001-180652 discloses a packaging frame material made of a flexible and thin paper material, or a packaging tray material inserted into a packaging lid material, and the packaging tray material is a rigid paper. Alternatively, an elliptical or circular blank made of biodegradable bioplastic film material is formed with transverse and longitudinal weakening lines or perforation lines in accordance with the projected dimensions of the confectionery, and at an angle of 45 degrees from the mutual intersection. Folding weak lines or perforation lines are formed, and a side wall capable of tightly covering the confectionery is formed by bending the weakening line or the perforation line, and the height of the top of the side wall is the height of the confectionery. And a confectionery packaging container in which subdivisions are marked outside the lateral and longitudinal weakening lines or perforation lines. That.

  The packaging tray material of such a packaging container has the long side wall and the short side wall in an upright state in close contact with the side surface on the long side and the side surface on the short side of the confectionery, respectively. Therefore, when trying to cut the confectionery with the knife in the state surrounded by the packaging tray material in this way, the blade of the knife becomes perpendicular to the long-diameter side wall of the packaging tray material. This prevents the cutting operation from being performed smoothly. That is, the confectionery cannot be cut with a kitchen knife while being surrounded by the packaging tray material.

  The present invention will be described below with reference to embodiments shown in the drawings. First, a first embodiment will be described. This embodiment is a paper tray-like container assembled using a base paper 10 as shown in FIG.

  As shown in FIG. 1, the tray-like container is assembled using a base paper 10 made of high-quality paper having a substantially rectangular shape. The base paper 10 is preliminarily joined with a polymer film such as a polyethylene film or a water-resistant resin layer at a portion corresponding to the inner surface thereof, thereby imparting water resistance. A rectangular bottom plate 11 is formed at the substantially central portion of the base paper 10, and a long side plate 13 can be bent at a long side portion of the bottom plate 11 via a fold line 12. It will be installed continuously. Further, a short side plate 15 is connected to the short side of the bottom plate 11 via a folding line 14 so as to be bent. A reinforcing piece 17 is foldably connected to a portion on the distal end side of the long side plate 13 via a fold line 16. The reinforcing piece 17 is formed with a notch 18 at each end portion on the tip side.

  Next, the joining piece 22 provided between the long side plate 13 and the short side plate 15 will be described. For example, the joining piece 22 is connected to the short side plate 15 so as to be bendable by a cutting line 23 that also serves as a bending line. The cutting line 23 has a perforated shape and has an intermittent connecting portion 24, and the connecting portion 24 is connected to an oblique edge of the short side plate 15. Note that a cut 25 is formed in the cutting line 23 so as to extend obliquely upward from the lower end of the connecting portion 24, whereby the cutting operation is performed stably and smoothly.

  FIG. 3 particularly shows an enlarged configuration for cutting the joining piece 22, and a plurality of connecting portions 24 formed on the cutting line 23 are left with a portion L above the cutting line 23. Formed on the lower side. Here, the length of L is at least 1/3 or more of the entire length of the cutting line 23. That is, the position of the connecting portion 24 is provided below 1/3 from the upper end of the cutting line 23. Further, the cut 25 formed obliquely from the lower end of the connecting portion 24 is formed obliquely upward, and the angle θ between the cutting line 23 and the cut 25 in FIG. 3 is set to a value of 90 degrees or less. Is done. In this way, when the connecting portion 24 having the incision 25 directed obliquely upward is formed below the upper end of the cutting line 23 except for a third, the cutting line 23 is broken with a light force. Become. On the other hand, if the position of the connecting portion 24 is formed extremely on the lower side, the form of the tray cannot be maintained.

  With such a base paper 10, a paper tray-like container is assembled as shown in FIG. That is, the bottom plate 11 is bent obliquely at the folding line 12 so that the long side plates 13 on both sides are opened outward, and obliquely at the folding line 14 so that the short side plate 15 is opened outward. Bend it. The inclination angle of the long side plate 13 and the short side plate 15 may be about 60 degrees with respect to the horizontal direction. Further, the reinforcing piece 17 on the distal end side of the long side plate 13 is bent outward at the folding line 16 so that it overlaps the upper end of the long side plate 13 at the upper end.

  Further, here, the long side plate 13 and the short side plate 15 are joined to each other by the joining piece 22. That is, the joining piece 22 is joined to the back side of the long side plate 13 and the joining piece 22 is long so that the edge portions at both ends of the long side plate 13 are aligned with the cutting line 23 at the base of the joining piece 22. Adhere to the outside of the side plate 13.

  In addition, about the structure of the cutting line 23 which has the connection part 24 and the notch | incision 25 in the part of the joining piece 22, as shown in FIG. 3, while forming the connection part 24 in three places, in the lower end side of those connection parts 24 A notch 25 is formed obliquely upward. Instead of such a configuration, as shown in FIG. 4, connecting portions 24 are formed at three locations along the cutting line 24, and left and right alternately with respect to the cutting line 23 on the lower end side of these connecting portions 24. You may make it form the cut | notch 25 so that it may become a reverse direction.

  According to the paper tray-shaped container having such a configuration, as shown in FIG. 5, for example, the meat 30 contained in the tray-shaped container can be cut using the knife 31 as it is. That is, when the blade of the knife 31 is inserted into the meat 30, the front side and the rear end of the knife 31 are pushed on the long side plate 13, which is connected to the outside of the bottom plate 11 so as to be bent. Then, when it is pushed down as it is, the portion of the cutting line 23 of the joining piece 22 is cut by the force of the knife 31, so that the long side plates 13 are opened outward. That is, the cut line 23 is provided with a short connecting portion 24, and an oblique cut 25 extends obliquely upward from the lower end of the connecting portion 24. The cut line 23 and the cut 25 intersect in a V shape, The connecting portion 24 is located at the crossing position. Accordingly, the connecting portion 24 is easily cut with a weak force, and the portions other than the cutting line 23 are not cut. The reinforcing piece 17 is folded and joined to the upper end portion of the long side plate 13 so that the long side plate 13 is not crushed before the cutting line 23 is cut.

  By the cutting line 23 having such a cut 25, the bottom plate 11 and the long side plate 13 form one continuous plane, as if the bottom plate 11, the long side plate 13 and the short side plate 15 A chopping board will be constructed. Therefore, the meat 30 can be cut with the knife 31 as it is. Therefore, the contents contained in the tray-like container can be cut using the knife 31 as they are, without using a cutting board, and can be cooked. In addition, it is not necessary to open the long side plate 13 to the outside in advance, and the long side plate 13 is automatically opened to the outside when the knife 31 performs the cutting operation. Therefore, the cooking operation of the contents contained in the tray-like container is extremely easy. Also, such a tray-like container is flat because the joining piece 22 connecting the long side plate 13 and the short side plate 15 is cut along the cutting line 23 as described above. This results in a less bulky advantage when discarded.

  Such a tray-like container is not only used for selling the meat 30 but also used for storing and selling various other foods in general. That is, foods such as sausages, pizza, vegetables, fruits, cakes, confectionery, etc. may be put in and displayed for sale. That is, it can be used for all foods sold at supermarkets and the like that are cut and eaten or cooked. Further, such a tray-like container is very convenient because it does not require a cutting board when cutting meat contained in a barbecue or the like outdoors.

  Next, another embodiment will be described with reference to FIGS. The paper tray-like container of this embodiment is assembled by a paperboard base paper 40 as shown in FIG. Here, the paperboard 40 is composed of high-quality paper, and at least the inner surface is joined with a polymer film such as a polyethylene film or a water-resistant resin layer is formed to provide water resistance.

  A curved fold line 42 is formed at a substantially central portion of the base paper 40 so that an intermediate portion in the length direction bulges to the side, and the long side plate 43 is formed by the fold line 42. Is continuously provided in the long side portion of the bottom plate 41. A short side plate 45 is formed on the short side of the bottom plate 41 via a linear fold line 44. In addition, a long side flange 47 is connected to the distal end portion of the long side side plate 43 via a curved fold line 46. A short side flange 49 is connected to the front end of the short side plate 45 via a fold line 48.

  Next, the joining piece 52 formed between the long side plate 43 and the short side plate 45 will be described. Between the long side plate 43 and the short side plate 45, an isosceles triangle is joined. A piece 52 is provided, and this joining piece 52 is connected to both ends of the short side plate 45 by a cutting line 53 so as to be bendable. That is, in the cutting line 53, the connecting portions 54 are intermittently formed at a plurality of locations in the form of perforations, and the cuts 55 are formed so as to extend obliquely upward from the lower ends of the connecting portions 54. Here, the angle of the cut 55 with respect to the cutting line 53 is set to an angle of 90 degrees or less. The connecting portion 54 is formed on the lower side of at least one third of the upper end side of the cutting line 53. Further, projecting pieces 58 are formed at both ends of the short side flange 49 so as to extend along the upper edge of the joining piece 52.

  FIG. 7 shows a state in which a paper tray is assembled with the base paper 40 having such a configuration. Here, the long side plate 43 is bent at a bent fold line 42, and the short side plate 45 is formed. Bend at the fold line 44. At this time, the bottom plate 41 is curved so that the middle portion in the length direction of the long side plate 43 is high and both ends are low. Then, the joining piece 52 positioned between the long side plate 43 and the short side plate 45 is bent at the cutting line 53 and joined and bonded onto the outer surface of the long side plate 43. At this time, the projecting pieces 58 extending from both side ends of the short side plate 45 support both ends of the flange 47 formed at the tip of the long side plate 43 from below. As a result, as shown in FIG. 7, a substantially ship-shaped paper tray-like container is assembled. In such a container, the bottom plate 41 is curved, and the upper edges of the long side plate 43 and the short side plate 45 are provided with flanges 47 and 49, respectively. Have.

  Also for such a container, the contents inside and stored in the bottom plate 41 can be cut as they are using a knife. That is, when the contents are to be cut by the knife, the leading edge and the trailing edge of the knife blade in the length direction respectively press the upper edge of the long side plate 43, and this force causes the root of the joining piece 52 to be cut. The connecting portion 54 formed on the side cutting line 53 is guided by the notch 55 and is broken by a light force. Accordingly, the connection between the long side plate 43 and the short side plate 45 by the joining piece 52 is released. Accordingly, when the contents are cut with a knife, the long side plates 43 on both sides and the short side plates 45 on both ends are in a flat state continuous with the bottom plate 41, thereby making it possible to easily cut the contents. .

  Next, a modification of the above embodiment will be described with reference to FIG. Said embodiment is comprised from the curve which the bending line 42 of the base side of the long side side board 43 curved (refer FIG. 6). Therefore, in such a tray-like container, the bottom plate 41 is curved such that the middle portion in the length direction of the long side plate 43 is high and both ends are low. Therefore, two folding lines 61 and 62 that are curved in opposite directions are formed on the base side of the long side plate 43 as shown in FIG. Further, fold lines 63 and 64 that are curved in opposite directions are formed on the base side portion of the short side plate 45. By such folding lines 61, 62, 63, 64, the bottom plate 41 becomes flat when assembled. Therefore, in addition to the reinforcing effect by the flanges 47 and 49 as in the first embodiment, the operability when cutting the contents with the knife is further improved.

  Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the two embodiments described above, and various modifications can be made within the scope of the technical idea of the present invention. For example, various design changes can be made to the dimensions and specific shape of the paper tray-like container in the above-described embodiment according to the type and size of the contents to be stored. Further, as the base papers 10 and 40, it is possible to use a water-resistant high-quality paper or other paper material in which a polymer film is bonded or a resin layer is formed not only on the inner surface but also on the outer surface.

  The present invention can be widely used as a tray-like container for storing contents such as various foods.
