[0021] 1. First Embodiment First, a shaker container according to the first embodiment of the present invention will be described with reference to Figures 1 to 22.

[0022] 1.1 Overview of the Shaking Container Figures 1 to 15 all show the overall configuration of the dispensing container 1 of the first embodiment. The dispensing container 1 contains, for example, a large number of tablet-shaped candies.

[0023] As shown in Figures 1 and 2, the dispensing container 1 comprises first and second frames 10 and 20 made of synthetic resin, and first and second wall portions 30 and 40 made of paper as a base material. Each of the first and second frames 10 and 20 has continuous peripheral walls 11 and 21 that form the outline of the container. Adhesive portions 12 and 22 are integrally formed around the inside of the peripheral walls 11 and 21. The peripheral edges of the back surfaces of the first and second wall portions 30 and 40 are adhered to the surfaces of the adhesive portions 12 and 22.

[0024] Notches 11a and 21a are formed in parts of the peripheral walls 11 and 21 of the first and second frames 10 and 20. A lid portion 25 that can be opened and closed is integrally formed in front of the notch 21a on the peripheral wall 21 of the second frame 20. As shown in Figure 14, when the first and second frames 10 and 20 are joined together, their respective notches 11a and 21a coincide, forming a single outlet. This outlet is opened and closed by the lid portion 25.

[0025] The following describes in detail each of the components that make up the dispensing container 1: the first frame 10, the second frame 20, and the first and second wall sections 30 and 40.

[0026] 1.2 First Frame Figures 16 to 18 all show the structure of the first frame 10. The first frame 10 is integrally molded from a synthetic resin such as polypropylene. As shown in Figure 16, the main outer shape of the first frame 10 is formed by the peripheral wall 11. The peripheral wall 11 as a whole forms a substantially rectangular contour. The main part of the outer surface of the peripheral wall 11 is composed of curved surfaces without corners (see Figure 18). The peripheral wall 11 is continuous along the substantially rectangular contour, except for the portion in which the notch 11a shown in Figure 17 is formed. On each of the two end faces of the peripheral wall 11 that face each other on both sides of the notch 11a, minute projections 11d extending in the vertical direction are integrally formed (see Figures 1 and 2).

[0027] An adhesive portion 12 having a roughly rectangular outline similar to the peripheral wall 11 is integrally formed on the inside of the peripheral wall 11. The surface of the adhesive portion 12 forms a step lower than the surface of the peripheral wall 11 (see Figure 18). A beam portion 13 is integrally formed approximately in the center of the adhesive portion 12. The beam portion 13 spans from one part to another approximately in the center of the adhesive portion 12. The surface of the beam portion 13 is at the same height as the surface of the adhesive portion 12 and forms a step lower than the surface of the peripheral wall 11 (see Figure 18). As shown in Figure 2, the peripheral edge of the back surface of the first wall portion 30 is bonded to the surface of the adhesive portion 12. In this embodiment, the back surface of the first wall portion 30 is not bonded to the surface of the beam portion 13. However, a portion of the back surface of the first wall portion 30 approximately in the center may be bonded to the back surface of the first wall portion 30.

[0028] As shown in Figures 17 and 18, a fitting groove 11b, locking claws 11c, and fitting shafts 14a for connecting with the second frame 20 are integrally formed on the back surface of the first frame 10. The fitting groove 11b is located near the lower edge of the circumferential wall 11. The fitting groove 11b is continuous over almost the entire circumference of the back surface of the circumferential wall 11, except for the portion where the notch 11a is formed. Each of the multiple locking claws 11c is formed at intervals on the back surface of the circumferential wall 11. The locking claws 11c have a length that reaches the fitting groove 11b. The lower end of the locking claw 11c faces the fitting groove 11b with a small gap between them. Each of the multiple fitting shafts 14a protrudes downward from the back surface of the circumferential wall 11. Here, only the fitting shaft 14a located approximately in the center of the back surface of the first frame 10 is integrally formed with the large-diameter first support column 14. The first support column 14 is integrally formed at the center of the back surface of the beam section 13.

[0029] 1.3 Second Frame Figures 19 to 21 all show the structure of the second frame 20. Like the first frame 10, the second frame 20 is also integrally molded from a synthetic resin such as polypropylene. As shown in Figure 20, the main outer shape of the second frame 20 is formed by the peripheral wall 21. The peripheral wall 21 as a whole forms a roughly rectangular outline. The main part of the outer surface of the peripheral wall 21 is composed of curved surfaces without corners (see Figure 21). The peripheral wall 21 is continuous along the roughly rectangular outline, except for the parts in which the notch 21a and the lid 25 shown in Figure 19 are formed.

[0030] As shown in Figure 19, the lid portion 25 is connected to the peripheral wall 21 via a hinge made of a thin synthetic resin film. The lid portion 25 can be opened and closed by the hinge. A receiving portion 25a, surrounded on all four sides by walls, is integrally formed on the inside of the lid portion 25. In addition, minute projections 25b extending horizontally, as shown in Figure 19, are integrally formed on each of the two sides of the lid portion 25 (see Figures 1 and 2).

[0031] As shown in Figure 20, an adhesive portion 22 having a roughly rectangular contour similar to the peripheral wall 21 is integrally formed on the inside of the peripheral wall 21. The surface of the adhesive portion 22 forms a step lower than the surface of the peripheral wall 21 (see Figure 21). As shown in Figure 19, a beam portion 23 is integrally formed in the approximate center of the adhesive portion 22. The beam portion 23 spans from one part to another in the approximate center of the adhesive portion 22. The surface of the beam portion 23 is at the same height as the surface of the adhesive portion 22 and forms a step lower than the surface of the peripheral wall 21 (see Figure 21). As shown in Figure 2, the peripheral edge of the back surface of the second wall portion 40 is bonded to the surface of the adhesive portion 22. In this embodiment, the back surface of the first wall portion 30 is not bonded to the surface of the beam portion 23. However, a portion of the back surface of the second wall portion 40 in the approximate center may be bonded to the back surface of the first wall portion 30.

[0032] As shown in Figures 19 and 21, a fitting claw 21b and a second support column 24 for connecting with the first frame 10 are integrally formed on the back surface of the second frame 20. The fitting claw 21b is located near the upper edge of the peripheral wall 21. The fitting claw 21b is continuous over almost the entire circumference of the surface of the peripheral wall 21, except for the portion where the notch 21a is formed. Each of the multiple second support columns 24 protrudes upward from the back surface of the peripheral wall 21. The diameter of the second support column 24 is the same as the diameter of the first support column 14 described above. A fitting hole 24a is formed in the center of the second support column 24.

[0033] Here, a second support column 24, corresponding to the first support column 14 of the first frame 10 described above, is integrally formed at the center of the back surface of the beam portion 23 of the second frame 20. A fitting shaft 14a formed in the first support column 14 is inserted into a fitting hole 24a formed in this second support column 24.

[0034] 1.4 First and second wall sections The first and second wall sections 30 and 40 have the same configuration. Therefore, the configuration of the first wall section 30 will be described, and the description of the configuration of the second wall section 40 will be omitted.

[0035] As shown in Figure 22, the entire first wall portion 30 has a roughly rectangular outline corresponding to the adhesive portion 12 of the first frame 10 described above. A semicircular gripping portion 31 is provided in the center of one of the shorter sides of the roughly rectangular first wall portion 30. The first wall portion 30 is made of paper with sufficient strength as a base material. The surface of the paper is coated with varnish. A plastic film is attached to the back of the paper with adhesive. Furthermore, printing is applied to the surface of the paper. When printing is applied to the surface of the first wall portion 30, the first wall portion 30 constitutes the wall of the dispensing container 1 and also serves the role of a conventional label. Therefore, when printing is applied to the surface of the first wall portion 30, the label sticker that was conventionally attached to the surface of the dispensing container becomes unnecessary.

[0036] The paper used as the base material for the first wall section 30 is preferably one selected from cup paper, coated cardboard, and virgin pulp. The basis weight of the paper is 50 to 500 g / m². 2 Within that range, especially 150-300 g / m 2 A range within this range is preferable.

[0037] The term "base material" refers to the main material constituting the first and second wall sections 30 and 40. While the first and second wall sections 30 and 40 are primarily made of paper, they may also be combined with other materials, such as varnish or plastic film, as described below. Conversely, the first and second wall sections 30 and 40 may be made solely of paper.

[0038] The varnish coated on the surface of the paper may be, for example, UV varnish (ultraviolet curing varnish). Alternatively, the surface of the paper may be coated with OP varnish (overprint varnish). An acrylic adhesive is preferred as the adhesive applied to the back of the paper. The plastic film attached to the back of the paper is preferably, for example, OPP (biaxially oriented polypropylene), CPP (unoriented polypropylene), or heat-seal OP (Oriented Polypropylene). The thickness of the plastic film is preferably in the range of 10 to 100 μm, and particularly preferably in the range of 15 to 40 μm. Such a plastic film is attached to the back of the first wall portion 30 in order to weld it to the surface of the adhesive portion 12 of the first frame 10 and the surface of the beam 13.

[0039] The semicircular gripping portion 31 of the first wall portion 30 is used to peel the first wall portion 30 from the adhesive portion 12 of the first frame 10. The diameter of the semicircular gripping portion 31 is, for example, in the range of 8 to 18 mm, and the radius of curvature of the semicircle is in the range of 4 to 9 mm. By setting these dimensions, an area of ​​the gripping portion 31 that is easy for the user to grasp with their fingers is obtained. When the back surface of the first wall portion 30 is welded to the surface of the adhesive portion 12 of the first frame 10, a part of the peripheral edge of the back surface of the gripping portion 31 is not adhered to the adhesive portion 12. When the user disposes of the shaker container 1, they can grasp the gripping portion 31 with their fingers and peel the first wall portion 30 from the first frame 10. The separated first wall portion 30 and the first frame 10 can be recycled separately. Note that the shape of the gripping portion 31 is not limited to a semicircle, and may be changed to other shapes that the user can grasp with their fingers.

[0040] 1.5 Merging the first and second frames Next, the configuration for combining the first frame 10 and the second frame 20 will be explained with reference to Figures 14, 15, 17-19, and 21.

[0041] The first frame 10 and the second frame 20 are joined by facing each other's back surfaces as shown in Figures 17 and 19, and pushing one of the first frame 10 or the second frame 20 into the other.

[0042] As shown in Figure 18, the multiple fitting shafts 14a of the first frame 10 all protrude downward beyond the lower end of the peripheral wall 11. These fitting shafts 14a serve as guides when connecting the first frame 10 to the second frame 20. That is, when connecting the first frame 10 to the second frame 20, first, the tips of each of the multiple fitting shafts 14a of the first frame 10 are inserted into the fitting holes 24a formed in the second support column 24 of the second frame 20. By inserting the tips of each of the multiple fitting shafts 14a into the fitting holes 24a, the first frame 10 and the second frame 20 are precisely positioned.

[0043] Subsequently, by pushing either the first frame 10 or the second frame 20 toward the other, the fitting claws 21b formed around the entire circumference of the upper end of the second frame 20 engage with the fitting groove 11b formed around the entire circumference of the lower end of the first frame 10. As shown in Figure 15, the fitting claws 21b engaged with the fitting groove 11b are pressed in the direction of the fitting groove 11b by the multiple locking claws 11c of the first frame 10. This firmly maintains the engagement between the fitting groove 11b and the fitting claws 21b over the entire circumference of both the first frame 10 and the second frame 20.

[0044] On the other hand, as shown in Figure 15, when the first frame 10 and the second frame 20 are joined together, the first support column 14 and the second support column 24 constitute a single support column that supports the two beam sections 13 and 23. That is, the fitting shaft 14a formed in the first support column 14 is inserted into the fitting hole 24a formed in the second support column 24. When the fitting shaft 14a is fully inserted into the fitting hole 24a, the lower end surface of the first support column 14 abuts against the upper end surface of the second support column 24. As a result, the first support column 14 and the second support column 24 become a single support column that does not move toward the center of the shaker container 1. This single support column supports the centers of the two beam sections 13 and 23, preventing the two beams 13 and 23 from bending. As a result, the strength of the center of the first and second wall sections welded to the surfaces of the two beams 13 and 23 is increased.

[0045] As shown in Figure 14, the first frame 10 and the second frame 20 are joined together so that their respective notches 11a and 21a align, forming an opening that is opened and closed by the lid 25. When the lid 25 is closed, two minute protrusions 25b formed on both sides of the lid 25 engage with two minute protrusions 11d formed on the first frame 10. Also, when the lid 25 is closed, the receiving portion 25a formed on the inside of the lid 25 fits into the opening.

[0046] 1.6 Welding of the first and second walls The peripheral edges of the back surfaces of the first and second wall portions 30 and 40 are welded to the surfaces of the adhesive portions 12 and 22 of the first and second frames 10 and 20, respectively. In addition, a portion of the back surfaces of the first and second wall portions 30 and 40, approximately in the center, is welded to the surfaces of the beam portions 13 and 23 of the first and second frames 10 and 20, respectively. Examples of methods for welding the first and second wall portions 30 and 40 include hot plate welding, hot melt welding, and ultrasonic welding.

[0047] Hot plate welding has the advantage of being able to generate a large amount of heat with relatively inexpensive equipment. Hot melt adhesives do not use organic solvents as adhesives and do not require a drying process, making them more environmentally friendly compared to adhesives. Ultrasonic welding can heat only specific areas to weld instantaneously, and also has the advantage of stable heat output even when welding is performed continuously.

[0048] Here, from the viewpoint of reducing the amount of synthetic resin used, the width of the adhesive portions 12 and 22 of the first and second frames 10 and 20 in the short-side direction is preferably within the range of 0.5 mm to 5 mm, and in particular, within the range of 2 mm to 3 mm. The back surfaces of the first and second wall portions 30 and 40 may be welded with the same width as the width of the adhesive portions 12 and 22 in the short-side direction, or they may be welded with a width less than the width of the adhesive portions 12 and 22 in the short-side direction.

[0049] Furthermore, the method of bonding the first and second wall portions 30 and 40 to the adhesive portions 12 and 22 is not limited to the welding described above, but may also be a bonding method using an adhesive, for example.

[0050] 1.7 Method for manufacturing tablet confectionery products Next, a method for manufacturing a tablet confectionery product in which a predetermined amount of tablet confectionery is contained in a dispensing container 1 will be described. The tablet confectionery product can be manufactured by one of the two methods described below.

[0051] As a first manufacturing method, first, a first semi-finished product of the dispensing container 1 is constructed by welding a first wall portion 30 to a first frame 10. Next, a second semi-finished product of the dispensing container 1 is constructed by welding a second wall portion 40 to a second frame 20. Then, a predetermined amount of tablet candy is placed on the back surface of either the first or second semi-finished product. After that, the first frame 10 of the first semi-finished product and the second frame 20 of the second semi-finished product are joined together. This completes the dispensing container 1 containing the predetermined amount of tablet candy.

[0052] As a second manufacturing method, first, a first semi-finished product of the dispensing container 1 is constructed by welding a second wall portion 40 to a second frame 20. Next, a second semi-finished product is constructed by joining a first frame 10 to the second frame 20 of the first semi-finished product. Then, a predetermined amount of tablet candy is placed inside the second semi-finished product through an opening on the surface of the first frame 10. After that, a first wall portion 30 is welded to the first frame 10 of the second semi-finished product. This completes the dispensing container 1 containing a predetermined amount of tablet candy.

[0053] 2. Second Embodiment Next, a dispensing container 2 according to a second embodiment of the present invention will be described. Note that the configuration of the second embodiment described below is illustrative, and the dispensing container of the present invention is not limited to the configuration of the second embodiment described below.

[0054] Figures 23 to 37 all show the overall configuration of the dispensing container 2 of the second embodiment. Figures 38 to 40 all show the configuration of the first frame 10 of the dispensing container 2. Figures 41 to 43 all show the configuration of the second frame 20 of the dispensing container 2. Figure 44 shows the configuration of the first and second wall portions 30 and 40 of the dispensing container 2.

[0055] The second embodiment of the shaker container 2 is primarily characterized by a first recess 16 formed in the first frame 10 shown in Figure 38 and a second recess 26 formed in the second frame 20 shown in Figure 42. Therefore, in the shaker container 2 of the second embodiment described below, components identical to those of the shaker container 1 of the first embodiment are denoted by the same reference numerals and their detailed descriptions are omitted.

[0056] As shown in Figures 38 to 40, a first recess 16 with a roughly semicircular cross-section is formed on the right side of the peripheral wall 11 of the first frame 10. As shown in Figure 38, the right side of the adhesive portion 12 of the first frame 10 is formed in a roughly semicircular shape corresponding to the shape of the first recess 16. Similarly, as shown in Figures 41 to 43, a second recess 26 with a roughly semicircular cross-section is formed on the right side of the peripheral wall 21 of the second frame 20. As shown in Figure 42, the right side of the adhesive portion 22 of the second frame 20 is formed in a roughly semicircular shape corresponding to the shape of the second recess 26.

[0057] As shown in Figures 23 and 24, the joining of the first and second frames 10 and 20 causes the first and second recesses 16 and 26 to coincide and form a single recess. As a result, as shown in Figure 37, the back surfaces of the right-center of the first and second wall portions 30 and 40 are not partially welded by the single recess.

[0058] When disposing of the dispensing container 2, the user can insert their fingertips into the single recesses formed by the first and second recesses 16 and 26, pinch the non-welded portion in the right center of each of the first and second wall portions 30 and 40, and peel each of the first and second wall portions 30 and 40 from the first and second frames 10 and 20, respectively. The first and second frames 10 and 20 can be recycled as recycled plastic. The first and second wall portions 30 and 40 can be recycled as recycled paper.

[0059] The diameters of the roughly semicircular first and second recesses 16 and 26 are, for example, within the range of 8 to 18 mm, and the radius of curvature of the semicircle is within the range of 4 to 9 mm. By using these dimensions, recesses of a size that allows the user's fingertips to easily fit are formed. Note that the shape of the first and second recesses 16 and 26 is not limited to a semicircle and may be changed to other shapes that allow the user's fingertips to fit.

[0060] 3. Effects According to the dispensing containers 1 and 2 of this embodiment described above, it is possible to significantly reduce the amount of synthetic resin used while maintaining high quality and high performance as packaging containers, thereby greatly contributing to the prevention of global warming. Assume that the dispensing containers 1 and 2 have the same vertical and horizontal dimensions as the actual dispensing container of the applicant's product name "Mintia® Breeze". In this case, the amount of polypropylene used by dispensing containers 1 and 2 can be reduced by approximately 40% compared to the actual dispensing container of the product name "Mintia® Breeze".

[0061] 4. Third Embodiment Next, we will describe the dispensing containers 1 and 2 according to the third embodiment of the present invention. Note that the configuration of the third embodiment described below is illustrative, and the dispensing container of the present invention is not limited to the configuration of the third embodiment described below.

[0062] 4.1 Substrate of the first and second walls In the dispensing containers 1 and 2 of the first and second embodiments described above, the base material of the first and second wall portions 30 and 40 may be a thin synthetic resin plate or film. The thickness of the synthetic resin plate or film is made thinner than the maximum thickness of the first and second frames 10 and 20. For example, as shown in Figures 15 and 37, the thickness of the first and second frames 10 and 20 is greatest at the peripheral walls 11 and 21. The thickness of the synthetic resin plate or film that forms the base material of the first and second wall portions 30 and 40 is, for example, 2 / 3 or less, preferably 1 / 2 or less, of the thickness of the peripheral walls 11 and 21.

[0063] The first and second wall portions 30 and 40, which are based on thin synthetic resin plates or films, are welded to the adhesive portions 12 and 22 of the first and second frames 10 and 20, similar to the first and second embodiments.

[0064] Furthermore, the surface of the synthetic resin plate or film that forms the base material for the first and second wall portions 30 and 40 is directly printed. In this case, the synthetic resin plate or film constitutes the wall of the dispensing container 1 and also serves the role of a conventional label. Therefore, when printing is applied to the surface of the synthetic resin plate or film that forms the base material for the first and second wall portions 30 and 40, the label sticker that was conventionally affixed to the surface of the dispensing container becomes unnecessary.

[0065] 4.2 Effects By using thin synthetic resin plates or films as the base materials for the first and second wall sections 30 and 40, it is possible to significantly reduce the amount of synthetic resin used while maintaining high quality and performance as a packaging container, thereby greatly contributing to the prevention of global warming.

[0066] For example, in the actual dispensing container of the applicant's product "Mintia® Breeze," if the portions corresponding to the first and second wall sections 30 and 40 are replaced with polypropylene plates with a thickness of 2 / 3 or less of the wall thickness of the dispensing container's perimeter, the total amount of polypropylene used in the dispensing container can be reduced by approximately 10%. Furthermore, if the portions corresponding to the first and second wall sections 30 and 40 are replaced with polypropylene plates with a thickness of 1 / 2 or less of the wall thickness of the dispensing container's perimeter, the total amount of polypropylene used in the dispensing container can be reduced by approximately 20%.

[0067] Furthermore, the dispensing containers 1 and 2 of the third embodiment exhibit a significant improvement compared to simply reducing the wall thickness of conventional dispensing containers. In other words, in order to reduce the wall thickness of conventional dispensing containers, it is necessary to narrow the mold cavity (gap). As a result, it becomes difficult to distribute the synthetic resin evenly into the narrow cavity when molding the dispensing container. Consequently, the wall thickness of the molded thin section becomes uneven, increasing the number of defective dispensing containers. In short, the thinner the wall thickness of the dispensing container, the lower the productivity of the dispensing container.

[0068] In contrast, in the third embodiment of the shaker containers 1 and 2, the first and second wall portions 30 and 40 can be manufactured independently of the first and second frames 10 and 20. Therefore, it is possible to make the wall thickness of the first and second wall portions 30 and 40 extremely thin. Furthermore, even if the wall thickness of the first and second wall portions 30 and 40 is reduced, this does not result in an increase in the number of defective products.

[0069] 5. Fourth Embodiment Next, a dispensing container 3 according to the fourth embodiment of the present invention will be described. Note that the configuration of the fourth embodiment described below is illustrative, and the dispensing container of the present invention is not limited to the configuration of the fourth embodiment described below. Furthermore, components similar to those of the dispensing containers 1 and 2 of the first and second embodiments described above are denoted by the same reference numerals, and detailed descriptions are omitted.

[0070] Figures 45 to 59 all show the overall configuration of the shaker container 3 of the fourth embodiment. Figures 60 to 62 all show the configuration of the first frame 10 of the shaker container 3. Figures 63 to 65 all show the configuration of the second frame 20 of the shaker container 3. Figure 66 shows the configuration of the first and second wall portions 30 and 40 of the shaker container 3. The shaker container 3 of the fourth embodiment has a simpler configuration compared to the shaker containers 1 and 2 of the first and second embodiments.

[0071] In comparison with the dispensing container 1 of the first embodiment, the first and second wall portions 30 and 40 of the dispensing container 3 of the fourth embodiment are rectangles with chamfered corners as shown in Figure 46, and do not have the grip portions 31 and 41 shown in Figure 2. Furthermore, the first and second frames 10 and 20 of the dispensing container 3 of the fourth embodiment do not have recesses corresponding to the grip portions 31 and 41 formed on the right-side surface of the peripheral walls 11 and 21.

[0072] On the other hand, in comparison with the dispensing container 1 of the second embodiment, the first and second frames 10 and 20 of the dispensing container 3 of the fourth embodiment do not have the first and second recesses 16 and 26 shown in Figure 24 formed on the right side of the peripheral walls 11 and 21.

[0073] As a result, the dispensing container 3 of the fourth embodiment is symmetrical in its front and back, left and right sides, and top and bottom surfaces, except for the lid 25. This dispensing container 3 of the fourth embodiment is composed of first and second frames 10 and 20 that significantly reduce the amount of synthetic resin used, and first and second wall portions 30 and 40 that serve as labels. Therefore, similar to the dispensing containers 1 and 2 of the first and second embodiments, the dispensing container 3 of the fourth embodiment can significantly reduce the amount of synthetic resin used while maintaining high quality and performance as a packaging container, thereby greatly contributing to the prevention of global warming.

[0074] 6. Fifth Embodiment Next, a dispensing container 4 according to the fifth embodiment of the present invention will be described. Note that the configuration of the fifth embodiment described below is illustrative, and the dispensing container of the present invention is not limited to the configuration of the fifth embodiment described below. Also, the same reference numerals are used for components similar to those of the dispensing containers 1 to 3 of the first, second, and third embodiments described above, and detailed descriptions are omitted.

[0075] Figures 67 to 81 all show the overall configuration of the shaker container 4 of the fifth embodiment. Figures 82 to 84 all show the configuration of the first frame 10 of the shaker container 4. Figures 85 to 87 all show the configuration of the second frame 20 of the shaker container 4. Figure 88 shows the configuration of the first and second wall portions 30 and 40 of the shaker container 4.

[0076] The dispensing containers 1 to 3 of the first, second, and fourth embodiments described above are relatively thick, box-shaped containers. On the other hand, the dispensing container 4 of the fifth embodiment is a thin, card-type container. Furthermore, the dispensing container 4 of the fifth embodiment, like the dispensing container 3 of the third embodiment, is symmetrical on the front and back, left and right sides, and top and bottom surfaces, except for the lid 25, and has a simpler configuration compared to the dispensing containers 1 and 2 of the first and second embodiments.

[0077] Here, as shown in Figure 68, a circular recess is formed in the center of the beam portion 13 of the first frame 10. As shown in Figure 81, this circular recess in the center of the beam portion 13 protrudes to the back side of the first frame 10. On the other hand, as shown in Figure 68, a second support column 24 is integrally formed in the center of the beam portion 23 of the second frame 20. As shown in Figure 81, when the first frame 10 and the second frame 20 are joined together, the second support column 24 in the center of the beam portion 23 comes into contact with the back side of the circular recess in the center of the beam portion 13. This prevents the bending deformation of the two beam portions 13 and 23. As a result, the centers of the first and second wall portions 30 and 40 welded to the adhesive portions 12 and 22 of the first and second frames 10 and 20 and the beam portions 13 and 23 are firmly supported by the two beam portions 13 and 23. As a result, even if the user grasps the center of the first and second walls 30 and 40 with their fingers, the first and second walls 30 and 40 will not dent.

[0078] The dispensing container 4 of this fifth embodiment also consists of first and second frames 10 and 20 that significantly reduce the amount of synthetic resin used, and first and second wall portions 30 and 40 that serve as labels. Therefore, similar to the dispensing containers 1 to 3 of the first, second, and fourth embodiments, the dispensing container 4 of the fifth embodiment can significantly reduce the amount of synthetic resin used while maintaining high quality and performance as a packaging container, thereby greatly contributing to the prevention of global warming.

[0079] 7. Other It should be noted that the configurations of the first to fifth embodiments described above are illustrative examples, and the dispensing container of the present invention is not limited to the configurations of the first to fifth embodiments.

[0080] For example, the contours of the first and second frames 10 and 20 are not limited to being approximately rectangular. They may be polygons other than rectangles, circles, or ellipses. For example, the surfaces of the adhesive portions 12 and 22 of the first and second frames 10 and 20 may be at the same height as the surfaces of the peripheral walls 11 and 21. In other words, the inner edges of the peripheral walls 11 and 21 may serve as the adhesive portions 12 and 22 for bonding the first and second wall portions 30 and 40. For example, the beams 13 and 23 are not limited to the shape and position shown in the drawings. Also, if the first and second wall portions 30 and 40 have sufficient strength, the beams 13 and 23 may be omitted. For example, the paper used as the base material for the first and second wall portions 30 and 40 is not limited to cup paper, coated cardboard, and virgin pulp. For example, the lid portion 25 is not limited to a configuration that opens and closes via a hinge. The lid portion 25 may be changed to a configuration that opens and closes by sliding, or a configuration that is detachable from the first and second frames 10 and 20. [Explanation of symbols]
