Description

  The present invention relates to a distribution package, and in particular, when a flexible bag is joined to a cover plate and folded around the folding position of the cover plate, a plurality of discharge ports are formed along the folding position. The present invention relates to a distribution package in which a plurality of types of contents are discharged through an outlet.

  For example, Japanese Laid-Open Patent Publication No. 11-301746, Japanese Laid-Open Patent Publication No. 2001-180761, Japanese Laid-Open Patent Publication No. 2001-328095, etc. propose a distribution package. These distribution packages are a combination of a hard cover plate and a flexible bag, and are configured to join the peripheral edge of the upper opening of the bag to the peripheral edge of the cover plate. When the cover plate is folded around the center folding position so as to be worn, a discharge port is formed at the bending position, and the contents are discharged through the discharge port. Such a distribution package is a large container because the contents filled in the bag, such as seasonings, additives, dressings, and other various foods, can be filled in a single volume. It is hygienic and convenient to handle compared to the food in it. Therefore, it tends to be widely used in the school lunch and restaurant industries.

  Such a distribution package has a structure in which the cover plate is made of polystyrene and a polyethylene bag is joined to the inside as a main material. A half cut cut is made at the folding position of the cover plate that forms the discharge port, and the discharge port opens when the cover plate is bent around the folding position where the half cut is formed. It is supposed to be formed. However, in the conventional distribution package, the portion where the outer polystyrene half-cut is formed is broken when it is folded, but the polyethylene bonded to the inner side of the lid plate is stretched without breaking. As a result, there is a foreseeable problem that the discharge port is not formed and the contents are not discharged. In addition, due to the half-cutting of the polystyrene part of the lid plate, there is an accident that the half-cutting part breaks during use or storage for use in logistics before use, which causes the contents to flow out. It was easy. That is, the discharge port is not correctly formed by being broken, or a half-cut causes the crack to cross the long side direction of the lid plate, and an accident is predicted. Moreover, since the half-cut cut was formed in the cover plate, the thickness of the cover plate could not be reduced.

  The problem with such a distribution package is the same in a distribution package that allows two types of contents, called twin types, to be simultaneously discharged from the corresponding discharge ports. In the twin-type distribution package, break openings are formed at two locations along the folding line of the cover plate, respectively, and so as to correspond to the discharge ports composed of such break openings. In addition, the bag is divided into two by a partition wall, or two types of bags are joined to a lid plate. When the lid plate is folded at the folding position, the contents contained in each space are discharged from the corresponding discharge ports. In such a twin type distribution package, the breakage was correctly performed and the contents had to be smoothly discharged from the discharge port. Smooth discharge operation could not be expected.

Japanese Patent Laid-Open No. 11-301746 JP 2001-180761 A JP 2001-32809 A

  The present invention will be described below with reference to embodiments shown in the drawings. 1 to 4 show the distribution package of the first embodiment. The package is composed of a cover plate 10 and a bag 11. The lid plate 10 has a three-layer structure of a sealant layer / polypropylene containing, for example, polypropylene / EVOH (ethylene-vinyl alcohol copolymer), and preferably has a thickness in the range of 0.1 to 2.0 mm. Is formed of a relatively hard material of 0.3 to 0.4 mm. The lid plate 10 may be made of PP alone or a multilayer body mainly composed of PP (may include a barrier layer such as EVOH or an adhesive layer). On the other hand, the bag 11 is a container in which, for example, a laminated structure of polypropylene and EVOH is formed and the contents are filled therein. And the peripheral part of the upper opening on the outer peripheral side of the bag 11 is joined to the peripheral part of the lower edge of the cover plate 10 and sealed in a state filled with contents. The material of the bag 11 may be PP, PP / EVOH / PP, PP / PE / EVOH / PE, or the like.

  The distribution package of the present embodiment is a distribution package in which an internal space is divided into two and discharge ports are formed in accordance with the respective spaces to discharge a plurality of types of contents. Examples of combinations of substances filled in such a distribution package include tomato ketchup / mustard, balsamic / olive oil, jam / margarine, mayonnaise / sauce, mayonnaise / dressing, honey / lemon, soy sauce / wasabi Sauce, mustard, tartar sauce / lemon, shabu sauce / yuzu, custard / strawberry sauce, etc.

  On the upper surface of the cover plate 10, a pair of protrusions 14 are formed on the left and right sides thereof so as to face each other. The protrusion 14 has a semicircular cross section, and includes a slope 18 that is gentle toward the back side, and an arc-shaped rib 21 is formed at substantially the center of the slope 18. Triangular protrusions 22 are formed at both ends in the length direction. With such a structure, the cover plate 10 has a predetermined rigidity.

  Next, in particular, the structure of the fracture portion will be described. The front end surface of the projection 14 is composed of an inclined surface 26 with respect to a bending position 25 indicated by a chain line in FIGS. That is, the front end of the protrusion 14 is inclined, and a V-shaped recess is formed between the inclined surfaces 26 on both sides. The inclined surfaces 26 on both sides are formed with conical protruding portions 27 or beak-shaped protruding portions so as to face each other. These conical protrusions 27 are in contact with each other at their contact portions 28 (see FIGS. 9 to 11), and these contact portions 28 constitute stress concentration points.

  The discharge port 29 is formed by such a pair of conical protrusions 27 that are abutted against each other. Moreover, the bag 11 on the lower surface of the lid plate 10 is divided into two spaces by a partition wall 12, and the two spaces are filled with contents separately, and each space is It communicates with a pair of discharge ports 29.

  Such opening of the distribution package is such that the distribution package shown in FIG. 3 is turned upside down, and thereafter, both ends of the lid plate 10 are bent upward with the folding position 25 as the center as shown in FIG. At the same time, the bag 11 is sandwiched between the bent portions of the lid plate 10. Although the bag 11 is filled with the contents, since the bag 11 is made of a flexible material, the bag 11 is crushed when the cover plate 10 is folded around the folding position 25. At the same time, due to the bending of the cover plate 10, stress concentrates on the abutting portion 28 on the tip side of the conical protruding portion 27 on both sides, and the abutting portion 28 breaks to form the discharge port 29. Therefore, when the cover plate 10 is pushed from both sides so as to be close to each other, the contents 60 in the bag 11 are pushed out through the discharge port 29 and a discharge operation is performed. Here, the contents 60 of the two spaces partitioned by the partition wall 12 of the bag 11 are discharged from the corresponding discharge ports 29, respectively.

  FIG. 6 particularly shows the opening operation by the conical protrusion 27. In the case of a two-layer structure, as shown in FIG. 6A, the outer side of the folding position 25 is biased upward. When the lid plate 10 is bent, a force in a direction away from each other acts on the conical protruding portions 27 on both sides, and the contact portion 28 is broken to form the discharge port 29. That is, when the inner layer 52 is provided on the inner side of the surface layer 51, the surface layer 51 and the inner layer 52 are broken together so as to be separated from each other at the portion of the conical protrusion 27. When the cover plate 10 has three layers as shown in FIG. 6B and is composed of a surface layer 51, an inner layer 52, and an innermost layer 53, the cover plate 10 is composed of a laminate of these three layers 51, 52, and 53. The conical protrusions 27 are broken together at the contact portion 28 to form the discharge port 29.

  FIG. 6C shows a conventional distribution package of this type, in which a half-cut 58 is formed in advance on the surface layer 56 and an inner layer 57 is provided inside the surface layer 56. When the cover plate 10 is bent, the surface layer 56 is broken to form an opening, but the inner layer 57 moves so as to be biased inward, thereby causing a defect that an opening error occurs. In the present application, the conical protruding portion 27 forms a shape that intersects with the inclined surface 26 of the protrusion 14 and is connected to the upper surface of the protrusion 14. Therefore, the connecting direction and the flow of the shape coincide with the opening direction, and the shape connecting from the inclined surface 26 to the upper surface is folded. Therefore, as shown in FIG. 6B, when the surface layer 51 and the innermost layer 53 are made of the same resin that can be cracked, the two layers are simultaneously broken. As a result, the soft and thin inner layer 52 is also broken.

  Next, another embodiment of the overall configuration will be described with reference to FIGS. In this embodiment, the shapes of the protrusions 14 located on both sides of the bending position 25 are not the same, and one is longer and the other is shorter. And about the protrusion 14 biased to both sides, those both-ends shape is reverse. Further, another protrusion 22 is disposed at the end of the shorter protrusion 14. These protrusions 22 are for increasing the rigidity of the cover plate 10. Even in such a configuration, the cover plate 10 is bent with the folding position 25 as the center, whereby discharge ports 29 are formed on both sides, and the two spaces defined by the partition walls 12 from these discharge ports 29 are formed. The contents filled therein are discharged.

  Next, the form of the protrusion 14 formed on the upper surface of the lid plate 10 will be described. 9 to 11 show the protrusion 14 having a semicircular cross-sectional shape. The protrusion 14 is formed with a gentle slope 18 on the back side thereof. The back side of the gentle slope 18 is formed as a flat surface 19, and a groove 20 is formed in the flat surface 19. An arc-shaped rib 21 is formed on the gentle slope 18.

  A conical protruding portion 27 is formed in a beak shape on the front end side of the protruding portion 14. The tip of the cone-shaped projecting portion 27 constitutes the contact portion 28, and when the cover plate 10 is bent around the folding line 25, the discharge port 29 opens below the contact portion 28.

  Next, the structure of another protrusion 14 will be described with reference to FIGS. The feature of this protrusion 14 is that a concavity 41 is formed on the front end side and on both sides. The concavity 41 prevents the protrusion 14 from being deformed, particularly on the front end side, and increases the rigidity. If the protrusion 14 is soft and easily deformed, a reliable breaking operation cannot be expected when the lid plate 10 is bent. On the other hand, when the recess 41 is formed, the rigidity of the protrusion 14 is improved, and a more complete opening operation is achieved.

  Next, another protrusion 14 will be described with reference to FIGS. The protrusion 14 has a substantially triangular cross-sectional shape, and the top surface has an arcuate cross-sectional shape. In addition, the structure of the cone-shaped protrusion part 27 formed in the inclined surface 26 of the front end side other than that is the same as the structure shown in FIGS.

  The projecting portion 14 shown in FIGS. 18 to 20 has a triangular cross-sectional shape, and the upper surface is constituted by a linear ridgeline. The rest of the configuration is the same as the protrusion 14 shown in FIGS.

  Next, the protrusion 14 shown in FIGS. 21 to 23 will be described. The projecting portion 14 has a trapezoidal cross-sectional shape, and a gentle slope 18 is formed on the back side, and an arc-shaped rib 21 is formed thereon. Further, the back side is formed as a flat surface 19, and a concave groove 20 is formed in the flat surface 19. The conical protrusion 27 formed on the inclined surface 26 on the front end side is the same as the conical protrusion 27 shown in FIGS.

  Next, various shapes of the cone-shaped protruding portion 27 will be described below.

  FIG. 24 shows a cone-shaped projecting portion 27 in which a triangular discharge port 29 is formed. Triangular inclined surfaces 34 on both sides intersect with a straight ridgeline, and the ridgeline is slanted so that the front end is lowered. ing. The ridge lines on both sides are in contact with each other at the contact portion 28. The abutting portion 28 is biased outward of the lid plate 10 with respect to the folding position 25, and when the lid plate 10 is bent along the folding line 25, the conical protrusions 27 on both sides abut. The stress concentrates on the portion 28 and is broken to form the discharge port 29.

  The configuration shown in FIGS. 27 to 29 is similarly formed with a discharge port 29 having a triangular inclined surface, and the triangular plate-like portions on both sides of the cone-shaped protruding portion 27 are triangular flat located on the upper surface. It intersects with the surface 35. Then, the apexes of the triangles on both sides and the apex of the flat surface 35 of the upper triangle intersect each other at the contact portion 28, and this is the stress concentration point. Therefore, when the lid plate 10 is bent with the fold line 25 as the center, the lid plate 10 is broken at the contact portion 28 constituting the stress concentration point, and the discharge port 29 is formed. Such a configuration is intended to avoid deformation of the sinking of the conical protrusions 27 due to the shapes of FIGS. When the flat triangle 35 becomes the top surface in this way, the deformation strength of the cone-shaped protruding portion 27 is further improved, and even if the lid plate 10 is bent slowly, the cone-shaped protruding portion 27 is hardly deformed.

  30 to 32, the discharge port 29 having a triangular inclined surface is formed, and the triangular plate-like portions on both sides of the cone-shaped protruding portion 27 are arranged on the triangular inclined surface 34 located on the upper surface. It is supposed to cross. Then, the apexes of the triangles on both sides and the apexes of the triangular plate-like portion 34 on the upper surface intersect each other at the contact portion 28, and this is the stress concentration point. Therefore, when the lid plate 10 is bent with the fold line 25 as the center, the lid plate 10 is broken at the contact portion 28 constituting the stress concentration point, and the discharge port 29 is formed.

  Thus, when the cone-shaped protruding portion 27 having the inclined triangle 34 arranged on the upper surface is used, the ease of breaking is improved, and when the lid plate 10 is bent and the discharge port 29 is opened, the lid plate 10 is slowly folded. Even if it is bent, the opening operation is surely performed. That is, in the case where the triangles on both sides of the cone-shaped protruding portion 27 intersect with each other with a linear ridge line as shown in FIGS. 24 to 26, the cone-shaped protruding portion 27 is likely to sink, so that it can be opened slowly. Not suitable. On the other hand, the structure shown in FIGS. 30 to 32 brings about an advantage that the opening operation is reliably achieved even when the lid plate 10 is bent slowly.

  Next, the configuration of FIGS. 33 to 35 will be described. In this configuration, the base-side portions of the plate-like portions on both sides of the cone-shaped protruding portion 27 are formed in an arc shape, and intersect with the inclined surface 26 at the front end portion of the projecting portion 14 in an arc shape. Thus, by making the base side of the cone-shaped projecting portion 27 into an arc shape, the cone-shaped projecting portion 27 gradually changes from the three-dimensional curved surface on the base side to the planar shape on the opening 29 side and easily absorbs deformation distortion. It becomes a shape and it becomes difficult to produce distortion. Therefore, when the cover plate 10 is bent, the conical protrusion 27 does not deform, stress concentration occurs in the contact portion 28, the contact portion 28 breaks, and the discharge port 29 is reliably formed. .

  36 to 38 further improve the structure of the cone-shaped protruding portion 27 formed on the inclined surface 26 of the protrusion 14, and the cone-shaped protruding portion 27 as a whole is formed of an arc-shaped surface. A triangular inclined surface 34 whose front end side is lowered is continuously provided. And the discharge port 29 formed when it fractures | ruptures in the contact part 28 of such a cone-shaped protrusion part 27 is a pentagon as shown in FIG. 37, and the upper part is a triangle, The lower part is a quadrangle, and a pentagonal discharge port 29 combining these two shapes is formed. Such a configuration provides good unsealing properties. That is, when the discharge port 29 is triangular, the folding angle of the container is large at the start of the break, and the force that pulls the cone-shaped protruding portion 27 so as to open is sufficiently transmitted to the discharge port 29 side, and the tensile force is also large. . However, when folding progresses and the folding angle becomes small, the folding force becomes difficult to be transmitted to the discharge port 29 side, and the force for pulling becomes small. This is because the pulling force is directed to both ends in the longitudinal direction of the container, whereas the discharge port 29 is ruptured in a direction different from that by 90 degrees. Therefore, here, the discharge port 29 is made the same as the bending direction of the container from the middle so as to enable good opening.

  The cone-shaped protruding portion 27 shown in FIGS. 39 to 41 is configured by a curved surface having a substantially arc shape as a whole, and a short ridge line is formed at the upper end on the tip side of the cone-shaped protruding portion, and this ridge line is formed on the circular arc surface. It is gradually changing. The cone-shaped projecting portion 27 intersects the inclined surface 26 with a curve at almost the entire circumference. That is, this configuration is obtained by further improving the conical protrusion 27 of FIGS. In the case of FIGS. 36 to 38, the triangle 34 on the upper surface of the cone-shaped projecting portion 27 intersects the inclined surface 26 with a line. Therefore, when the lid plate 10 is bent, the shape connecting the inclined surface 26 and the fracture start point 28 is the triangle 34, so that the triangle 34 on the upper surface of the cone-shaped protruding portion 27 and the inclined surface 26 intersect with each other. Therefore, distortion is likely to occur at the intersection of the triangular portion 34 and the arcuate inclined surface 26. Therefore, in FIGS. 39 to 41, the triangle 34 on the upper surface of the cone-shaped protruding portion 27 is replaced with one ridge line, and the intersection shape of the upper ridge line of the cone-shaped protruding portion 27 and the inclined surface 26 is point-connected. Therefore, it is possible to obtain the effect of absorbing the deformation strain with the circular arc on the inclined surface 26.

  Next, another embodiment will be described with reference to FIGS. This embodiment is obtained by further improving the embodiment shown in FIGS. Here, it is the cone-shaped protrusion part 27 which makes | forms substantially arc shape, Comprising: The part which touches the inclined surface 26 is made into the cone-shaped protrusion part 27 comprised by circular arc shape. And the wall surface of the cone-shaped protrusion part of both sides cross | intersects by the ridgeline which inclines below toward the front, and the front end side of this ridgeline is the contact part 28. FIG. In other words, the ridge line rises from the stress concentration point 28 that is the starting point of the fracture toward the inclined surface 26. With such a configuration, stress concentration is particularly effectively performed at the contact portion 28, and only a small force is applied. Thus, the discharge port 29 is more reliably formed, and a good opening property is obtained.

  Next, another configuration of the cone-shaped protruding portion will be described with reference to FIGS. The cone-shaped projecting portion is composed of a ridge line whose upper surface is a straight line, and constitutes an upper projecting portion 42 at a portion of the ridge line on the inclined surface 26 side. The cone-shaped protruding portion 27 that forms the upper protruding portion 42 is pulled up above the inclined surface 26 when the lid plate 10 is bent, thereby increasing the stress concentration at the fracture start point 28, The ease of breaking was improved. Therefore, the concentration of stress for opening at the contact portion 28 is more reliably performed.

  Next, another conical protrusion 27 will be described with reference to FIGS. The cone-shaped projecting portion 27 has a substantially arc shape as a whole, and the base side portion is in contact with the inclined surface 26 by an arc surface. In particular, the discharge port 29 opened downward from the portion of the abutting portion 28 constituting the stress concentration point has a substantially triangular upper portion and a rectangular lower portion, and an upper portion. Both sides of the triangle are recessed inward. Even with such a structure, the contact portion 28 that is the break start point is formed thicker than the other end surfaces at the end surface of the fractured surface of the discharge port 29 of the cone-shaped protruding portion 27. By being recessed in the shape, it becomes possible to form the sheet more uniformly than the other end faces, and the breakage of the contact portion 28, which is the break starting point, is improved. Accordingly, the effect of stress concentration at the contact portion 28 when the lid plate 10 is bent is further improved.

  Next, still another embodiment will be described with reference to FIGS. In this embodiment, as shown particularly in FIGS. 51 and 52, the protrusions 14 arranged on the cover plate 10 are different from each other on both sides of the folding position 25. By arranging the two storage spaces on both sides of the partition wall 12 in an L shape, it is possible to fill even a highly viscous content. That is, in the case of the structure shown in FIG. 1 and FIG. 2, the internal space divided into two has an elongated shape, and therefore, a plurality of filling nozzles may be required when filling a high-viscosity content. There is. However, since the liquid containing paste-like substance has a property of spreading radially, the interior space is made into an L-shaped pocket, the length of the content storage portion is shortened, and the possibility of filling with a single nozzle is increased. It is expanding.

  Also, as shown in FIGS. 53 to 55, the shapes of the protrusions 14 that are arranged along the fold line 25 and that form a pair of discharge ports 29 that are adjacent to each other are also different. That is, one protrusion 14 on the right side in FIG. 53 extends long on the back side, and has a gently inclined surface 18 and a flat surface 19 on the rear side as shown in FIGS. 51 and 52 in particular. On the other hand, the other adjacent protrusion 14 on the left side in FIG. 53 is curled in an arc shape and has a small lengthwise dimension. If the dimensions in the back direction are reduced in this way, the top surface may become thin and the balance of strength may be lost. As shown in FIG. 54, the upper end of the projecting portion 14 is constituted by a small arc shape at the top of the cross section in the width direction orthogonal to the length direction, and such an arc is connected by a curved line continuous with relatively large arcs on both sides. The structure is made. As a result, the contents are smoothly discharged from the respective discharge ports 29 even if they are adjacent to each other on both sides and the shape of the protrusion 14 is different.

  56 to 59 show still another embodiment. The feature of this embodiment is that the shape of the protrusions 14 disposed on both sides of the folding line 25 is slightly changed. In other words, as shown in FIG. 58, these protrusions 14 have a substantially semicircular shape in the width direction orthogonal to the length direction of the protrusions 14, as viewed from the fold line 25. In addition, the concave portions 41 are respectively formed in the front end side portion on the inclined surface 26 side of the projecting portion 14 having such a semicircular cross-sectional shape.

  According to such a configuration, it is possible to give high rigidity while making the shape of the protrusion 14 an ordinary semicircular shape, thereby preventing deformation of the protrusion 14 and enabling smooth discharge. Will be.

  Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention. For example, various changes can be made to the dimensions of the cover plate 10 or the capacity of the bag 11 in the above embodiment. Moreover, the substance filled in such a container is widely applicable to various substances, and is not limited to a specific food.

  The present invention can be widely used as a distribution package used to fill and supply two types of contents corresponding to a single use amount.
