[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a measuring and packaging container for powder and granule contents, particularly contents that are not sensitive to moisture.

[0002]

[Prior art and its problems]

 Although used for liquid packaging, brick-type box-shaped containers and gable-type gable-top box-shaped containers are known. (See, for example, Japanese Utility Model Laid-Open No. 63-169415).

However, since the spout of the brick-type box-shaped container does not have a resealing function, it is particularly suitable for animals such as powder, granular food, seasonings, coffee, medicine, pesticides, dog food, etc. It is not suitable as a packaging container for feed, fertilizer, etc.Also, the gable-type gable-top box-shaped container has a plastic sealing member at the spout, which has a resealing function. Since it protrudes from the container body, there is the inconvenience that it lacks stacking suitability. It is also known that a slit is provided on the side plate of the container for the purpose of measurement, and the slit is closed with a transparent film. Outside air flows into the container from the slit and / or the film. However, it is not suitable as a container for contents that dislike moisture as described above.

The object of the present invention is to prevent moisture absorption of the contents not only before opening but also after opening, so that alteration and modification of the contents can be easily prevented, and the contents can be stacked and evenly distributed. , Providing packaging containers that can be reasonably used by weighing.

[0005]

[Means for Solving the Problems]

 The structure of the present invention, which solves the problems of the prior art, has an outer side of an opening for taking out contents formed at a required portion of a container body having a moisture-proof property, and one end portion having a wider area than the opening is formed on the outer surface of the container body. A moisture-proof sealing sheet with heat-sealing and tabs formed on the other end is placed, while at least peeling and sticking to the inner surface of the sealing sheet excluding the portion corresponding to the opening. Repeatable adhesive is attached, and the sealing sheet is attached to the outer surface of the container body via this adhesive so that it can be unsealed and resealed, and the contents can be measured on any side plate of the container body. The transparent window portion is provided, and the inside of the transparent window portion is closed with a transparent film having a gas barrier property.

[0006]

[Action]

 The peeling action of the sealing sheet is stopped at the fixed portion of the sealing sheet and the container body, the opening is properly opened, and the resealing is easy and the moisture-proofing effect on the contents can be properly performed. Further, for example, it is possible to evenly spread the contents by filling a pesticide such as granules and granules for home gardening and shaking the container body while carrying it by hand. Further, the contents can be sprayed while visually observing the transparent window portion for measurement, and the excess or deficiency of the pesticide spraying can be adjusted appropriately, and the film having the transparent window portion closed can enhance the moisture-proof effect.

Next, the details of the embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment in which a packaging container has a box shape, FIG. 2 is a cross-sectional view of a see-through window portion, FIG. 3 is a developed front view of a sealing sheet portion, and FIG. 4 is an opening portion provided with a sealing sheet. FIGS. 5 to 13 are front views of the container showing the embodiment of the transparent window portion. The shape of the see-through window may be any shape such as a column, a circle, a triangle, a quadrangle, and a polygon.

Reference numeral 1 denotes a box-shaped container body made of a material coated with, for example, linear Rhoden polyethylene (not shown) on the inner and outer surfaces of a paper board 2, and one of the top plates 3 of the container body 1. On the side, an opening 4 having a droplet shape in a plan view is formed. The large-diameter portion of the opening 4 is arranged so as to be close to the one side ridge 1a of the container body 1 so that powder or granular contents can be easily poured out. 5 is a moisture-proof sealing sheet that is wider and longer than the opening 4, that is, has a large area. This sealing sheet 5 has a composite film structure, for example, on the upper surface of an aluminum foil sheet. The polyester film is heat-fixed under biaxially-stretched condition, and is composed of an aluminum foil sheet and a linear rhoden polyethylene film laminated on the lower surface of the aluminum foil sheet. Then, one end of the sealing sheet 5 is heat-sealed 6 to the outer surface of the top plate 3 that constitutes the container body 1 with a required width, and the other end of the sealing sheet 5 is opened and resealed. A knob 7 is provided for this purpose. The heat seal 6 has an opening stopping action when the knob 7 is held and the sealing sheet 5 is opened. In addition, the lower surface of the sealing sheet 5, that is, the lower surface of the linear Rhoden polyethylene film that constitutes the sealing sheet 5, is peeled off at least in the area corresponding to the opening 4 and the area excluding the knob 7 described above. The adhesive 8 that can be repeatedly applied is attached. Further, as shown in FIG. 1, the sealing sheet 5 is folded straight at the corner ridge 1a of the container body 1 and attached along the surface of the end face side plate 9 forming the container body 1.

As shown in FIGS. 3 and 4, the entire outer peripheral edge of the opening 4 formed in the container body 1 and the sealing sheet 5 are heat-sealed 10 in a narrow width, and a layer of the adhesive 8 is interposed therebetween. This heat seal 10 is used to prevent moisture from permeating. Furthermore, an auxiliary sealing sheet 11 having a larger area than the opening 4 and made of, for example, a Rhoden polyethylene material is put on the heat seal 12 on the inner surface of the container body 1 including the opening 4 constituting the container body 1. The auxiliary sealing sheet 11 portion is heat-sealed 13 to the sealing sheet 5 portion corresponding to the opening 4 under an adhesive strength condition larger than the breaking strength of the auxiliary sealing sheet 11. According to this structure, the opening 4 is closed by the double structure of the sealing sheet 5 and the auxiliary sealing sheet 11, and the moisture-proof effect before opening is further enhanced. When opening, the auxiliary sealing sheet 11 heat-sealed to the sealing sheet 5 is broken to open the opening 4, and the broken auxiliary sealing sheet 11 is attached to the sealing sheet 5. It is in.

On the other hand, as shown in FIG. 1, a measuring transparent window portion 15 having a slit structure is provided in a vertical posture in a lower half portion of a central portion of a side plate 14 constituting the container body 1, and the transparent window portion 1 is provided. As shown in FIG. 2, a film 16 having transparency and gas barrier properties is heat-sealed on the inner surface of the side plate 14 on which the transparent window portion 15 is formed, and the transparent window portion 15 is hermetically closed. The film 16 is made of, for example, a composite material such as a polyethylene film, PET, a silicon vapor deposition layer, a dry laminate, and a polyethylene film, and has appropriate transparency and a high gas barrier property. Although not shown, a measuring scale is attached to one side or both sides of the side window 14 of the transparent window portion 15. Further, as shown in the figure, by providing the transparent window portion 15 on the side plate 14 which is a side plate parallel to the dispensing direction of the contents and which is the front face when the container body 1 is gripped by the left hand, for example, pesticide In the case of diluting etc. with an aqueous solution, the pesticide is dispensed while being measured with the left hand, and the aqueous solution can be stirred with the right hand. However, the transparent window portion 15 is not necessarily attached to the side plate 14 and can be visually measured and dispensed even if the transparent window portion 15 is provided on another side plate portion. is not.

5 to 13 show a modified example of the transparent window portion 15. FIG. 5 shows a perspective window portion 15a having a slit structure formed in a vertical posture substantially in the central portion of the plate surface of a required side plate that constitutes the container body 1 so that the contents can be weighed from the initial stage of dispensing. is there. In FIG. 6, a transparent window portion 15b having a slit structure is formed in a vertical posture at a portion close to a corner ridge on one plate surface side of a required side plate. In this embodiment, the see-through window portion 15b is formed at a position close to the corner ridge on the right side of the paper, but it may be formed at a position near the corner ridge on the left side of the paper. In FIG. 7, the side window width of this side plate is effectively used in the required side plate, and the transparent window portion 15c having a slit structure is formed in an inclined posture from the upper portion of one side to the lower portion of the other side. In this embodiment, the see-through window portion 15c is tilted downward from the upper right part of the side plate toward the lower left direction, but it may be formed in a reverse tilted position. FIG. 8 shows a modification of the embodiment shown in FIG. 7, in which the transparent window portions 15d of the slit structure are formed in two tilted postures in parallel, and also in two upper and lower stages. The slope is the same level as the upper end. In this embodiment, the two transparent window portions 15d are formed in upper and lower two stages, but it is possible to have a multi-stage structure, and therefore it is not limited to the embodiment. In FIG. 9, the transparent window portions 15e having a relatively short slit structure in a vertical posture are formed in a zigzag pattern in substantially the entire length of the central portion of the required side plate, and the upper and lower end levels of the left and right transparent window portions 15e are aligned with each other. It is something that is done. In this embodiment, two sets of the transparent window portions 15e are arranged in a zigzag pattern, but a large number of sets may be used. In FIG. 10, the transparent window portions 15f having the same short slit structure as those in FIG. 9 are divided into left and right staggered arrangements near the right and left corners of the required side plate, and the left and right transparent window portions 15f are formed. The upper and lower end levels are made to coincide with each other. FIG. 11 shows that a large number of small-diameter circular transparent window portions 15g are formed in a vertical line shape at a portion close to the corner ridge portion of the required side plate, and the transparent window portions 15g are arranged at required measurement intervals. Each of the see-through windows 15g is configured to have a function of a measuring scale. Further, in this embodiment, the row of the transparent window portions 15g is formed on the left side of the side plate in the drawing, but it may be formed on the right side. The shape of the see-through window portion 15g is not limited to a circular shape, but may be an arbitrary shape such as a triangle, a quadrangle, or a polygon. In FIG. 12, a relatively wide and short see-through window portion 15h is provided vertically in the lower center of the required side plate. This example is mainly based on the confirmation effect of the residual amount rather than the measurement of the content. FIG. 13 shows a modified example of FIG. 12, in which a transparent window portion 15i having a relatively large diameter and a circular shape is formed in two upper and lower stages at the lower center of the required side plate. Similar to the embodiment of FIG. 12, this embodiment also aims at confirming the residual amount of the content rather than weighing the content. Although not specifically shown, the transparent window portions 15a to 15i shown in the respective embodiments of FIGS. 5 to 13 are hermetically closed by a film 16 having transparency and gas barrier properties. Of course.
