Description

  The present invention is used for refilling powders and granules, and is provided with a cup-shaped container body mainly made of paper, a ring-attached part, a seal-like lid material, and further an overcap. The present invention relates to a part-attached paper container in which the parts are joined to an opening of a main body.

  In the paper container with parts according to the present invention, the parts include a ring, a flange projecting outwardly, and a funnel portion for use in transferring contents such as instant coffee. Specifically, it is integrally molded with high-density polyethylene (HDPE) or the same paper as the container body.

  By the way, as such a container for refilling, a packaging bag made of a synthetic resin film is often used. For example, it is a self-supporting gusset bag provided with a reseal zipper part above.

On the other hand, as a conventional structure provided with a ring inside the opening of the container main body, there is a structure mainly intended to increase the strength of the container. Specifically, the flange of the ring is placed on the upper surface of the flange or curl portion formed by projecting the upper end of the body portion of the container body outward, and the upper surface of the flange of the container body is joined to the lower surface of the flange of the ring. It is. Further, a sheet-like lid member having a barrier property is attached to the upper surface of the flange of the ring, or the opening of the container body is sealed with a cap.

  However, the above-mentioned conventional structure requires opening the gusset bag or container in advance when refilling the contents such as instant coffee, and the contents are easily spilled during refilling. There was a problem of being troublesome. Furthermore, since the contents such as instant coffee come into contact with the outside air when refilling, the scent and flavor of the contents are impaired, and there is a problem that moisture in the atmosphere is absorbed.

  The present invention has been made to solve such a problem, and as a result of various studies, it is needless to say that refilling can be performed easily and reliably and the risk of fragrance and flavor being impaired can be reduced. It is an object of the present invention to provide a paper container with parts that can reduce the wraparound of the contents from the part to the outer part as much as possible.

In order to solve the above technical problems, there a cup-like container body in which the paper mainly, and part of the ring with a sheet-shaped lid member, in the parts with paper container and a overcap Te, parts provided with a substantially the same diameter cylindrical ring with the opening of the container main body, a flange projecting outwardly is provided at the upper end of the-ring, also a tapered toward the opening in the ring It features a funnel is set so that the leakage DOO opening and the flange is substantially the same height level position, the path over tool flange is joined to the upper surface of the opening of the container main body, flange A sheet-like lid material having a barrier property is attached to the upper surface, and the lid material is provided with a plurality of strength weak points extending radially from the center of the lid material, above the lid material , Obaki turbocharger-up with the peripheral portion of the undercut portion Wear is the opening of the container body is sealed, after removing the O Bakya' flop, by pressing the lid at the opening of the sorting containers, are broken split lid is along the strength weak parts by the opening of the funnel is opened, while collecting the contents housed in the container body in a funnel part to the central part, directly from the open mouth of the funnel to the sorting container contents by Pas over Tsu The feature is that it can be poured.

  In the paper container with parts configured in this way, the overcap is removed, and then the container body is turned upside down as shown in FIGS. 5 and 6, and the jar mouth portion which is an example of a container for refilling the hopper funnel To the position where it can be fitted inside. Powders such as instant coffee in the container body have also flowed down from the hopper into the funnel, but are held by the lid. Next, as shown in FIGS. 7 and 8, a pressing force is applied to the container body so as to push the funnel toward the mouth of the jar. This pressing force acts as a force for the upper part of the cylinder, which rises in a cylindrical shape from the main body of the jar, to push the lid member. That is, the mouth portion of this jar functions as a force that pushes up the lid and pushes it into the space on the cross-sectional triangle between the hopper ring and the funnel. The lid member to which the pressing force is applied is broken and divided into a plurality of divided pieces, for example, along radial perforations and cut lines which are strength weak points provided in advance in the lid member. At the same time, the funnel enters the mouth of the jar. As a result, the opening of the funnel of the hopper is opened, and powder such as instant coffee in the container body is guided and flowed into the jar all at once while being guided to the center by the funnel of the hopper.

  In the above configuration, since the ring flange and the funnel opening are located at substantially the same level, the funnel opening is pressed and sealed by the lid material existing on the ring flange. By pressing, the adhesion between the lid material and the funnel opening is improved, and it is possible to successfully prevent the useless gap from being formed between the lid material and the funnel opening. In addition, since the flanges of the parts are mounted on the opening of the container body and joined together, the attachment position with respect to the container body is always constant.

Therefore, this invention has the following effects.
The paper container with parts of the present invention is completely different from conventional standing pouches and the like, because the lid is pushed and pressed by pressing the container body against the mouth of the refill container. Because it is in direct communication with the refill container, the refill operation can be performed easily and reliably with very simple operation, there is little risk of touching the contents to the outside air, and the aroma and flavor may be impaired. Few.

  Particularly in the present invention, since the opening of the funnel is firmly pressed by the lid material and the overcap and an unnecessary gap is hardly formed between the lid material and the powder as the contents, the opening of the funnel and the lid material It is possible to reduce as much as possible the risk of sneaking out of the funnel. Therefore, when refilling, the risk that the mouth and the periphery of the refill container will be inadvertently soiled by the wrapping powder is reduced, and it can be used in a sanitary manner. At the same time, the parts are always attached to the container body at a fixed position by the flange, so that a stable mounting state can be ensured, an accurate filling operation is possible, and the wraparound of the powder is prevented more accurately. it can.

In the above configuration, as described in claim 2, it is desirable that the funnel is provided with a cylindrical guide duct integrally from the end edge of the opening.
Compared to the fact that the funnel has an inclined wall that abuts the mouth of the refill container, and its abutment posture tends to be less stable, the cylindrical guide guide connected to the funnel can be reliably inserted into the mouth of the refill container. . Therefore, the powder guide to the mouth of the refill container, the scattering of the powder being filled out of the container, and the contact with the atmosphere and moisture can be reduced, and the risk of fragrance loss can be reduced. . In particular, it is more effective for use in powders that are easily affected by air and moisture.

Further, as described in claim 3, it is desirable that the upper end of the opening of the container main body is provided with a flange or a curled portion protruding outward.
Since the strength of the opening of the container body can be increased and deformation can be reduced, the installation position of the parts can be maintained as expected and the parts can be held firmly, making it more difficult to create a gap between the funnel opening and the lid. is there.

  Hereinafter, an embodiment when the paper container with parts of the present invention is applied to the instant coffee refilling container 1 will be described in detail with reference to the drawings.

  In addition, this invention is fundamentally applicable to the whole thing which the part provided with the funnel was joined to the opening part, and the content can be refilled efficiently. Therefore, it goes without saying that the present invention is not limited to the examples described in the following embodiments.

  First, as shown in FIGS. 1 and 2, the refill container 1 includes a container body 2, a hopper 3, a sheet-like lid member 4 having a barrier property, and an overcap 5.

The container body 2 has a bottomed cylindrical shape, and a rectangular piece of paper is used as the base material. This paper cylinder is composed of a paper layer, an aluminum foil layer, a polyethylene terephthalate layer, and a low-density polyethylene layer in order from the outside, and a composite with high gas barrier properties (oxygen, water vapor, content-derived volatile components). The material is adopted. A known technique is employed as the laminating means. For example, it is a general method such as laminating or coating. In order to produce the container body 2, the rectangular paper pieces having high gas barrier properties as described above are rounded into a cylindrical shape, the left and right sides are polymerized, and the overlapping portions are used as adhesive margins as appropriate. As the joining means, an adhesive is used, heat-sealing, or a known means is appropriately employed. As shown in FIGS. 1 and 2, the upper end is wound in an annular shape toward the outside, and the curled portion 6 is integrally formed.

As shown in FIGS. 1 to 3, a hopper 3 (hereinafter simply referred to as a hopper) that is an example of a part is fitted in the opening 2 </ b> A of the container body 2. Specifically, the hopper 3 is made of the same material as the container body 2 or an appropriate resin material such as high-density polyethylene (HDPE) or polypropylene whose thickness is set to 0.8 mm. The hopper 3 includes a rising wall 3A (hereinafter simply referred to as a ring) as a ring. The ring 3A is integrally provided with a flange 3B projecting outward at its upper end, and its lower surface is placed on the upper end of the opening 2A of the container body 2, that is, the upper end surface 6A of the curled portion 6, Are fitted into the opening 2A. In addition, a funnel 3 </ b> C composed of a wall that inclines upward and toward the center integrally with the lower end edge of the ring 3 </ b> A. The taper over angle of the funnel 3C is at least 20 °, more preferably set to 40 to 45 °. Further, the upper end of the funnel 3C of the hopper 3, that is, the opening 3C1, is designed to be arranged at substantially the same height position, that is, substantially on the same plane as the upper end surface of the flange 3B. As the joining means, the most preferable means such as heat fusion, high frequency welding, use of an adhesive, etc. are appropriately employed.
In addition, 6B in the figure is a step generated in the curled portion 6, but is well sealed by a sealant layer 7 (described later) formed in the innermost layer of the sheet-like lid member 4.

The lid 4 having a barrier property is sealed at the upper end of the hopper 3.
As shown in FIG. 4, the lid 4 having a barrier property has an innermost layer 7 of a polyethylene sealant layer, a polyethylene terephthalate layer 8 outside the sealant layer 7 and an adhesive layer 9 outside the metal foil. A composite sheet having a high gas barrier property to which the layer 10 is adhered is adopted, and the innermost sealant layer 7 is provided with a plurality of strength weak points 11 radially from the center thereof. The metal foil layer 10 including the sealant layer 7 is easily broken by the portion 11 and is easy to open.

Moreover, as shown in FIGS. 1 , 2, and 5, the overall shape of the lid member 4 is substantially the same diameter as the opening 2A of the container body 2, specifically, a circular shape having a diameter of about 90 mm. The part 3 is appropriately attached to the upper surface of the flange 3B. Generally, heat fusion means is employed. However, in this case, the upper edge of the funnel 3C, that is, the upper edge of the opening 3C1 is merely in contact. Rapid opening of the apertures 3 C1 of the funnel 3C, and, in order to facilitate.

Furthermore, as shown in FIGS. 1, 4, and 5, the lid member 4 having the barrier property has a plurality of perforations or cut lines (perforations in the illustrated example) as the strength weakening portions 11 radially from the center. Is provided so as to reach the innermost sealant layer 7 and the polyethylene terephthalate layer 8. The metal foil layer 10 including the innermost sealant layer 7 is easily broken by the perforation or the cut line which is the strength weak point portion 11, and is easily opened. As shown in FIGS. 1 and 5 , the perforations or cut lines are three straight lines intersecting each other at the center, and the length of the perforation is set to 9 mm and the joint is set to 1 mm. The number of three is a minimum number for achieving the intended purpose of the present invention. Further, although it depends on the size of the lid member 4, the desirable upper limit is ten. On the contrary, if the number is 10 or more, there is a possibility that the strength of the lid member 4 is weakened, which is not preferable. Ideally, there are 3 to 8 (eight examples are shown in FIG. 13).

Overcap 5, before Kiyo body 2 of the same material or high density polyethylene which is set to a thickness of about 0.8 mm (HDPE), an appropriate resin such as polypropylene is employed, as shown in FIGS. 1-3 The cover body 4 is externally fitted to the opening 2A of the container body 2 to protect the lid member 4 and to keep the inside hygienic. In particular, an undercut 5B is provided at the lower end of the peripheral hanging wall 5A. The undercut 5B is elastically engaged with the lower surface of the curled portion 6 of the container body 2 to maintain the fitted state.

Task of accommodating the instant coffee P powdery on the inner portion of the container 1 refill the according to the invention is generally carried out through the opening 3C1 of the hopper 3.

Next, how to use the refill container 1 configured as described above will be described.
First, remove the overcap 5, then as shown in FIG. 6 and FIG. 7, the container body 2 upside down, jar 1 2 of the cylindrical mouth portion 1 which is an example of a container for refilling the funnel 3C of hopper 3 2 Assign to the position where A can be internally fitted. The instant coffee P in the container body 2 has also flowed down from the hopper 3 into the funnel 3 </ b> C, but is held by the lid member 4. Then, as shown in FIGS. 8 and 9, the container body 2, to load the pressing force so as to push towards the funnel 3C to jar 1 2 of the mouth portion 1 2 A. The pressing force, jar 1 2 of the mouth portion 1 2 A, in general acts as a force for cylindrical upper part rising cylindrically from the body breaks down the lid 4. That is, the mouth portion 1 2 A of the jar 1 2 pushes up the lid member 4, which functions as a force to push in the space S on the triangular section between this hopper 3 of the ring 3A and funnel 3C. The lid member 4 to which the pressing force is applied is provided with perforations which are strength weak points 11 in a radial manner. Therefore, it is very easy to break and divide into a plurality of divided pieces along the perforation. Is done. At the same time, the funnel 3C is entering the jar 1 2 of the mouth 1 a 2 A. As a result, the opening 3C1 funnel 3C of the hopper 3 is opened, instant coffee P in the container body 2, the funnel 3C of hopper 3, while being guided to the center, guided flow down to the stroke in jar 1 in 2 The Jar 1 2 The refill container 1 having been subjected to replenishment to is discarded. In the figure, 2B is the bottom of the container body 2.

Until the instant coffee P in the container body 2 is unsealed, it is completely sealed by the lid 4 and does not come into contact with the atmosphere, so that the airtightness in the refill container 1 is kept high. The jar 1 2 of the mouth portion 1 2 fitted into the A engaged the funnel. 3C without compromising spill the instant coffee P jar 1 2 to the outside, also, us it yet greens exposing unnecessarily to the outside air. Therefore, the possibility that the fragrance and flavor are impaired can be reduced as much as possible.

The important point is, until the refill is performed, the rim of the funnel 3 C of the opening 3C1 is in close contact lid member 4. Furthermore, it is more firmly adhered by the pressing force of the overcap 5 on it. As a result, the funnel 3 C hardly unnecessary gap is formed between the opening 3C1 and the lid 4 of a slightly occurs if, instant coffee P in the container body 2 from flowing to the outside of the funnel 3 C We can prevent fear well. As a result, when the refill, fear of inadvertently contaminate the mouth 1 2 A and the surrounding jar 1 2 This wraps around it instant coffee P becomes small, it can be used hygienically. In addition, since the hopper 3 is always attached to the container main body 2 at a fixed position by the flange 3B, a stable attachment state can be secured, an accurate filling operation can be performed, and the wraparound of the instant coffee P can be performed. This can be prevented more accurately.

  Further, since the curled portion 6 of the opening 2A of the container body 2 can increase the strength of the opening 2A and reduce deformation, the installation position of the hopper 3 is properly maintained as expected, and the hopper 3 is firmly held. The gap between the 3C opening 3C1 and the lid member 4 can be made more difficult to occur.

  As a result of performing a performance test of the finished lid member 4, the central portion was successfully broken. Incidentally, the breaking strength was 100 N or less. In the permeated liquid check test at the step 6B (see FIG. 1) of the opening 2A using a paper cup, no leakage was observed. Furthermore, the example which the cover material 4 peels from the opening part 2A of a paper cup at the time of high temperature preservation was not seen. Moreover, the barrier property of the whole lid | cover material 4 obtained the preferable result as inferior to an aluminum lid | cover material. There was no odor generation compared to the hot melt lid.

  In the embodiment described above, a partially different structure as described below can also be adopted.

Specifically, as shown in FIGS. 10 and 11, the case is applied to the container body 2 that does not include the curled portion 6 in the opening 2 </ b> A.
In this configuration, the projecting dimension of the flange 3B of the hopper 3 is the same as that applied to the container body 2 provided with the curled portion 6. The undercut 5B is elastically engaged with the lower surface of the flange 3B by shortening the hanging dimension of the hanging wall 5A of the overcap 5 by the vertical dimension of the curled portion 6.
Other configurations are the same as those in the above embodiment.

Further, as another configuration, as shown in FIG. 12, the hot path 3 tubular integrally from an opening edge of the opening 3C1 above, preferably it may be provided with a cylindrical guide 3D of the same diameter to the upper end. Needless to say, the upper end of the cylindrical guide 3D and the height level of the flange 3B are formed to be the same.

The guide 3D is helpful for being accurately inserted into jar 1 2 of the mouth portion 1 2 A. In the hopper 3 with a tapered only easy displacement per position of the aperture 3C1 in the mouth portion 1 2 A of the jar 12 is Yayamosureba tend to inadvertently spilling the instant coffee P outside of the jar 1 2 if a cylindrical guide 3D, since the guide 3D can enter from the mouth 1 2 a to the inside of the jar 1 2, by inadvertently spilling the instant coffee P outside of the jar 1 2 There is no fear of it.

  In the above embodiment, instant powdered coffee is used as the contents, but it can be applied to other fluids of food and non-food. For example, water-soluble milk (powdered milk), cocoa, tea, or a combination thereof. Furthermore, it is a toner of a copying machine in addition to dried mashed potatoes and other dried foods, sauce or gravy powder, soup powder and the like.

Further, as an alternative to jar 1 2, coffee powder tank of a coffee-making apparatus, and further it can be applied to such a toner refill container of the copying machine.

(Example)
First, by the laminating method, [container outside] paper layer (basis weight 300 g / m ² ) / adhesive layer / aluminum foil layer (7.0 μm) / polyethylene terephthalate layer (12 μm) / adhesive layer A low-density polyethylene layer (50 μm) [inner side of container] laminated material was produced. As the bottom member, [outside of container] low density polyethylene layer (20 μm) / paper layer (basis weight 230 g / m ² ) / low density polyethylene layer (20 μm) / aluminum foil layer (7.0 μm) / adhesive layer / A laminated material having a configuration of polyethylene terephthalate layer (12 μm) / adhesive layer / low density polyethylene layer (50 μm) [inner side of container] was prepared. Using these laminated materials, a cup-shaped container main body having a curled portion on the outer periphery of the upper end of the trunk portion was produced by a cup molding machine manufactured by PMC. Next, the hopper 3 provided with the ring 3A, the flange 3B, and the funnel 3C was produced by injection molding using high-density polyethylene (Mitsui Chemical 2100K). The ring 3A, the flange 3B, and the funnel 3C were each formed to have a thickness of about 0.8 mm. Furthermore, a laminate composed of an aluminum foil layer (15 μm) as the metal foil layer 10 / adhesive layer 9 / polyethylene terephthalate layer (12 μm) 8 / low density polyethylene layer (40 μm) as the sealant layer 7 (lower side) A material was produced, and a lid material was produced using this laminated material.

Then inserting the cup-shaped container body mentioned above the anvil, a body portion fixed with supports the curl portion of the body portion upper from the lower side, the opening of the barrel upper end inside the hot path ring of the upper end Was inserted and inserted so as not to protrude upward from the upper end of the curled portion, and the outer surface of the ring was joined to the inner surface of the opening using a welding machine.

  The instant coffee was then filled into the container body through the funnel opening of the part. Finally, the lid material is heat-sealed by the heat seal method on the upper surface of the curled portion to seal the upper end of the container, and an overcap is further fitted on the lid material to attach the paper container with parts. Produced.

  Moreover, the container main body which is not provided with a curl part was produced with said method and means.

Furthermore, the tubular guide and relieved path that provided integrally produced by the above method, means.

All of the obtained products are completely different from conventional standing pouches and the like, and the refilling operation can be performed easily and reliably with a very simple operation. It was found that the flavor was maintained.
In particular, the opening 3C1 of the funnel 3C was firmly pressed by the lid member 4 and the overcap 5, and there was no evidence that the instant coffee P had turned around outside the funnel 3C. In addition, in any of the plurality of test bodies, the hopper 3 was always in a fixed position with respect to the container body 2 as expected, and a stable attachment state was ensured.
