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

  The present invention is basically provided with a cap having a funnel with a rising wall and / or an auxiliary member for refilling, for transferring contents, containing additives and ingredients to the contents, etc. The present invention can be applied to all aspects of the stool. 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 refilling container 1 includes a cylindrical container body 2, a cap 3, a sheet-like lid member 4 having a barrier property, a refilling auxiliary member 5, and a refilling auxiliary member 5. It consists of a lid 6 that closes an opening 5D (described later).

  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 paper, aluminum foil, polyethylene terephthalate, and low-density polyethylene in order from the outside, and a composite material with high gas barrier properties (oxygen, water vapor, content-derived volatile components) is used. Is done. 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 annularly wound outward and the curled portion 2 </ b> B is integrally formed.

  A cap 3 is fitted into the opening 2A of the container body 2 as shown in FIG. The cap 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 cap 3 includes a rising wall 3 </ b> A around it, and the rising wall 3 </ b> A is fitted into the opening of the container body 2. In addition, a funnel 3B that is integrally inclined from the lower end edge of the rising wall 3A to the upper side and toward the center is provided. The taper angle of the funnel 3B is set to at least 20 °, more preferably 40 to 45 °. The instant coffee P (see FIG. 5) in the container body 2 works by the funnel 3B to be collected in the center. Further, the upper end of the rising wall 3A is provided with a flange 3C placed on the upper end of the container body 2, that is, the upper end surface 2B1 of the curled portion 2B.

  The base material of the hermetic seal 4 is a single layer or laminated structure made of plastic, paper, and aluminum, and when the contents need to have a barrier property, it is desirable to provide the barrier property. As an example, uniaxially stretched polyethylene is used, and polyethylene, aluminum foil, and polyethylene are sequentially laminated and subjected to surface treatment. As a processing means, a known technique is adopted, which is a general technique such as laminating or coating. An easy peel material having a thickness of 15 to 100 μm is used for the inner surface, ie, the lowermost layer, of the hermetic seal 4 adhered on the upper end surface 2B1 of the curled portion 2B of the container body 2 so as to adhere with strength that allows easy opening. . As shown in the figure, the overall shape is a circle having substantially the same diameter as the cap 3, and the peripheral edge portion 4 </ b> A is just attached to the collar portion 3 </ b> C of the cap 3, that is, the top surface of the cap 3 as appropriate. Generally, it is heat-sealed.

  As shown in FIGS. 3 and 4, the overall shape of the above-described hermetic seal 4 has a circular shape with substantially the same diameter as the opening 2 </ b> A of the container body 2, specifically about 90 mmφ, and the peripheral edge 4 </ b> A is the container body 2 Is appropriately attached to the upper end of the opening 2A, that is, the upper end surface 2B1 of the curled portion 2B. Generally, it is heat-sealed. However, although it may be affixed to the upper end surface of the rising wall 3A of the cap 3, the upper end edge of the funnel 3B of the cap 3, that is, the upper edge of the opening 3B1 is simply in contact with it. It is as.

  From one peripheral edge of the hermetic seal 4, a pull-out opening piece 41 of a narrow strip shape having a width approximately the same as the opening diameter of the opening 3 </ b> B <b> 1 of the funnel 3 </ b> B of the cap 3, with its one end 41 </ b> A connected integrally, The seal seal 4 is extended to a length slightly longer than 1.5 times the diameter of the hermetic seal 4, and a knob 42 is integrally provided at the extended end. The pull-opening piece 41 formed in this way is folded back at the connection point portion of the peripheral edge and is superposed on the upper surface of the sealing seal 4 to reach the side opposite to the one end 41A. It is formed so as to hang down on the outer wall of the main body 2.

  Further, as shown in FIG. 1, the drawing / opening piece 41 is connected to the connection point of the drawing / opening piece 41 with the sealing seal 4, that is, at the meeting portion between the base end 41 </ b> A of the drawing / opening piece 41 and the peripheral edge of the sealing seal 4. A notch 43 is provided along the drawing direction. This is because the pull-out opening piece 41 can be more accurately torn from the sealing seal 4 and the accuracy of opening is improved. That is, by the action of the cut 43, the pull-open piece 41 is cut into strips (bands) with a narrow width that is substantially the same as the opening diameter of the opening 3B1 of the funnel 3B. The cut 43 may be provided as necessary. Further, when the sealing seal 4 is mainly made of paper, in order to perform tearing more efficiently, linearly with the same width as the width of the drawing / opening piece 41 from the left and right of the connection point of the drawing / opening piece 41. Cut line perforations can also be provided that traverse the hermetic seal 4.

  The refilling auxiliary member 5 has a cap shape and is made of polyethylene. A peripheral wall 5A that fits outside the opening 2A of the container body 2 is provided in the periphery, and protrudes upward at the center of the top surface 5B that is continuous with the upper end of the peripheral wall 5A (from the diameter of the opening 3B1 of the funnel 3A of the cap 3) (Large) cylindrical wall 5C is integrally provided to form an opening 5D. Since the opening 5D obtained by the cylindrical wall 5C is internally fitted in an opening of a refill container 9 described later, the instant coffee P can be well prevented from directly touching the outside air during refilling, or the instant coffee P can be inadvertently spilled. It can be prevented from falling.

  The lid 6 is made of polypropylene and seals the opening 5D of the refill auxiliary member 5. The outer wall 5A is externally fitted to keep the inside hygienic.

  As shown in FIG. 3, the refilling auxiliary member 5 includes a gap 7 between the top surface of the cap 3. This is for facilitating extraction when the extraction opening piece 41 of the sealing seal 4 is extracted and opened. The structure for obtaining this gap 7 is as follows.

  That is, the thickness of the peripheral wall 5A of the refilling auxiliary member 5 is increased. Specifically, the dimension is set to be larger than the sum of the thickness of the peripheral wall 2B of the container body 2 and the thickness of the rising wall 3A of the cap 3. Then, on the inner surface of the lower end of the thick peripheral wall 5A, a step portion 5F is formed by recessing a predetermined dimension upward from the lower end edge 5E, specifically, approximately half of the vertical height of the peripheral wall 5A. As a result, when the refilling auxiliary member 5 is put on the opening 2A of the container main body 2, the upper end of the opening 2A of the container main body 2 is brought into contact with the stepped portion 5F, and the top surface of the refilling auxiliary member 5 is placed. A gap 7 is obtained between the lower surface of 5B and the opening 2A of the container body 2. The gap 7 is formed by partially cutting out the peripheral wall 5A or by forming it in a slit shape by being elongated in the side, so that the extraction opening piece 41 can be extracted.

In addition, although the peripheral part of the said sealing seal 4 will be pressed by the ceiling surface of the step part 5F, since it is not a pressing force which becomes resistance to pulling out the extraction opening piece 41, this extraction opening piece 41 of Pulling out can be done smoothly.
Further, the gap 7 is not always necessary. What is necessary is just to employ | adopt as needed.

  4 is an inspection window 8 provided in the bottom 2C of the container body 2, and a hole 8A is provided in the center of the bottom 2C, and a transparent sheet or a resin flat plate 8B is hermetically sealed in the opening. By sticking, it is configured to check the internal state such as the instant coffee refill status. This inspection window 8 is also provided as necessary.

Next, the operation of the refill container 1 of the first embodiment configured as described above will be described.
As shown in FIG. 5 (A), the lid 6 is first removed, and then the container body 2 is turned upside down as shown in FIGS. 5 and 6 (as shown in FIG. 6 (A). The lid 6 may be removed after the main body 2 is turned upside down], and the peripheral wall 5A of the refilling auxiliary member 5 is fitted into the mouth of the jar 9 as an example of a refilling container. Next, as shown in FIG. 6B, the knob 42 of the seal 4 is picked with a fingertip and pulled horizontally. Then, as shown in FIG. 6 (C), the drawing / opening piece 41 is operated by the notch 43 provided in the meeting portion with the sealing seal 4 (see FIG. 2), and only this drawing / opening piece 41 is the sealing seal 4. Is torn along its pulling direction. As a result, as shown in FIGS. 5 and 6C, the opening 3B1 of the funnel 3B of the cap 3 as a part of the opening of the container body 2 is opened, and an example of the contents in the container body 2 The instant coffee P is guided down into the jar 9 while being guided to the center by the funnel 3B of the cap 3. Therefore, the instant coffee P is not likely to spill out of the refill container 9 due to the peripheral wall 5A of the refilling auxiliary member 5 fitted inside the mouth of the jar 9 and the funnel 3B. There is no fear of touching, and the possibility of impairing the aroma and flavor can be reduced as much as possible.

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

Specifically, this will be described below with reference to FIGS.
This other structure can obtain the same effect as the above-described embodiment and can be provided at a low cost by reducing the number of parts used.

  In this structure, the refilling container 1 basically includes a container body 2 shown in FIG. 7, a hermetic seal 10, and a refilling auxiliary member 11 shown in FIG.

  First, as shown in FIG. 8, the hermetic seal 10 is basically formed of a laminated structure in which an upper layer mainly composed of paper and a lower layer mainly composed of a plastic film are formed through a release layer. Is attached to the upper end edge of the peripheral wall of the opening 2A of the container body 2 through the lower seal layer 10B. More specifically, the upper layer is mainly made of paper and is formed by laminating plastic film, aluminum foil, etc., and the lower layer is laminated by plastic film, paper, aluminum single layer or at least two or more of them. The thickness is 15 to 100 μm.

  The lower layer seal 10B is bonded to the upper layer seal 10A with an easily peelable adhesive and a wax-based release varnish at the peripheral part. In order to form an opening in the central part, leaving the peripheral part. The upper seal 10 </ b> A is inseparably intimately joined in a circular shape. And since it is a hermetic seal mainly made of paper, as shown in FIGS. 10A and 10B, a half cut or a perforation 10C (perforation in the illustrated example) is provided at the boundary between the two. Yes. Needless to say, these half cuts or perforations 10C extend from the lower layer to the upper layer.

  Further, a strip-shaped pulling-opening piece 101 having a predetermined width is provided from one peripheral edge of the hermetic seal 10, and one end 101 </ b> A is integrally connected, and the other end is provided with a knob 102. 10 is superposed and extended to the side opposite to the one end 101 </ b> A, and the knob 102 is set to a size such that a part of the knob 102 hangs down on the outer wall of the container body 2. Further, as shown in FIGS. 10A and 10B, the base end of the extraction opening piece 101, that is, a portion connected to the periphery of the sealing seal 10 is also half-cut or perforated 10D (sewing machine in the illustrated example). Eyes) and serves to separate the upper and lower layers of the hermetic seal 10 with the release layer. Therefore, it is desirable that the position to be provided is a position slightly deviated outward from the portion where the sealing seal 10 and the curled portion 2B of the container body 2 are bonded.

  Therefore, when the pull-open piece 101 is peeled off, the peripheral portion of the lower seal 10B is left in a donut shape at the upper end of the peripheral wall of the opening 2A of the container body 2 as shown in FIG. The container body 2 is opened by being peeled off together with the upper seal 10A.

As shown in FIG. 9, the refilling auxiliary member 11 has a circular cylindrical shape opened up and down, and is made of polyethylene.
The thickness of the peripheral wall 11A of the refilling auxiliary member 11 is increased. Specifically, it is desirable to make the wall thickness about twice that of the peripheral wall 2B of the container body 2. Then, on the inner surface of the lower end of the thick peripheral wall 11A, a stepped portion 11F is formed by recessing a predetermined dimension upward from the lower end edge 11E, specifically about half of the vertical height of the peripheral wall 11A, Accordingly, when the refilling auxiliary member 11 is put on the opening 2A of the container main body 2, the upper end of the opening 2A of the container main body 2 is configured to come into contact with the stepped portion 11F. In addition, a slit 11G that communicates with the inside and outside of the circumferential wall 11A is provided at the same height level as the ceiling surface of the stepped portion 11F, and the circumferential wall 11A corresponding to the central portion in the longitudinal direction of the slit and the like. A pullout opening 11H is formed by partially cutting out, so that the pullout opening piece 101 and the upper seal 10B can be pulled out.

  In addition, although the peripheral part of the said sealing seal 10 will be pressed by the ceiling surface of the step part 11F, since it is not the pressing force which becomes resistance to pulling out the extraction opening piece 101, extraction of this extraction opening piece 101 is carried out. Can be done smoothly.

The operation of the above embodiment configured as above will be described.
As shown in FIG. 7, the opening 2 </ b> A of the container body 2 is hermetically sealed with a hermetic seal 10. In this state, the store is displayed and sold. Further, the refilling auxiliary member 11 is sold as a set.

  In order to perform refilling, first, the refilling auxiliary member 11 is externally fitted to the opening 2A of the container body 2 so that the peripheral wall on the side of the peripheral wall 11A where the extraction opening 11H is provided is positioned at the lower position. Next, as shown in FIG. 11, the container body 2 is turned upside down, and the peripheral wall 11 </ b> A of the refilling auxiliary member 11 is externally fitted to the mouth portion of the jar 9 which is an example of a refillable container. Next, the knob 102 of the hermetic seal 10 is picked with a fingertip and pulled in the horizontal and horizontal direction. Then, as shown in FIG. 10, the peripheral portion of the lower seal 10B is left in a donut shape at the upper end of the peripheral wall of the opening 2A of the container body 2, and the central portion is peeled off together with the upper seal 10A. Withdrawn, the opening 2A of the container body 2 is opened. By this opening, the instant coffee P, which is an example of the contents in the container body 2, is guided down into the jar 9 at once.

  Therefore, in this embodiment, the refilling operation can be easily performed, and the instant coffee P is not likely to spill out of the jar 9 due to the peripheral wall 11A of the refilling auxiliary member 11, and may be exposed to the outside air more than necessary. The possibility of impairing the scent and flavor is reduced as much as possible.

  In addition, the parts used are the seal seal 10 and the refilling auxiliary member 11 which are remarkably small in number of parts. Needless to say, the structure is simple and the manufacturing and processing are very simple, resulting in a very low price. Can be provided.

  In addition, as shown in FIG. 12, it is desirable that the other end of the drawing / opening piece 101 is adhered to the peripheral wall 2B of the container body 2 with a sealing material 13 such as an adhesive tape.

Further, as another configuration, a structure as shown in FIG. 13 can be employed.
This further embodiment shows a structure without the gap 7 employed in the embodiment shown in FIG. Accordingly, the step portion 5F provided in the refilling auxiliary member 5 is not provided.

Specifically, as shown in FIG. 13, the peripheral wall 5A of the refilling auxiliary member 5 is formed to have the same thickness as the top surface 5B and the cylindrical wall 5C. And when covering the container main body 2, it comprises so that the sealing sheet 4 may be directly pressed by the lower surface of this top | upper surface 5B in an outer peripheral area rather than the cylinder wall 5C.
Since the pressing force is not a pressing force that resists pulling out the pulling / opening piece 41, the pulling / opening piece 41 can be pulled out smoothly.
Further, the upper edge of the extraction opening 5G is formed at the same height level as the lower surface of the top surface 5B.

  It should be noted that the sealing seal 4 shown in the embodiment of FIGS. 1 to 6 and the sealing seal 10 shown in the embodiment of FIGS. Absent.

  In each of the above embodiments, 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 powder appropriately combined with these. 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 the jar 9, it can also be applied to a coffee powder tank of a coffee making device, and a toner replenishing container of a copying machine.

Example 1
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 cap 3 provided with the rising wall 3A, the funnel 3B, and the flange 3C was manufactured by injection molding using high-density polyethylene (Mitsui Chemicals 2100K). The rising wall 3A, the funnel 3B, and the flange 3C were all formed to have a thickness of about 0.8 mm. Furthermore, [Upper] Transparent vapor-deposited polyethylene terephthalate layer (12 μm) formed by vapor-depositing metal / Ester-urethane two-component adhesive layer for dry lamination / polyethylene terephthalate layer (15 μm) / ester for dry lamination -A laminated material composed of a low-density polyethylene layer (50 µm) [lower side] as an adhesive layer / sealant layer composed of a urethane-based two-component curable type was produced, and a hermetic seal was produced using this laminated material. The shape of the hermetic seal was 90 mm in diameter, and the pull-open piece extended from one end was 210 mm in length and 30 mm in width.
In the first embodiment, the base end connected to the edge 4A of the hermetic seal of the pull-open piece is not provided with a cut.

  Next, the cup-shaped container body described above is inserted into the anvil, the curl portion at the upper end of the body portion is supported from the lower side, the body portion is fixed, and the cap 3 is inserted into the opening inside the upper end of the body portion. The outer surface of the rising wall 3A was joined to the inner surface of the opening using a welding machine.

  Next, instant coffee P was filled into the container body through the opening of the funnel of the part. Finally, the above-mentioned sealing seal is heat-sealed by the heat seal method on the upper surface of the curled portion to seal the upper end side of the container, and the refilling auxiliary member 5 is fitted on the lid member for refilling. A container was prepared.

(Example 2)
Further, the sealing seal 4 provided with the notch 43 at the base end of the extraction opening piece 41, that is, the boundary with the edge of the sealing seal 4, was produced by the above-described method and means.

(Example 3)
Further, the hermetic seal 10 shown in FIGS. 7, 8 and 10 was produced by the following method and means.
[Upper side] Paper layer (single art paper with a basis weight of 104.7 g / m ² ) / peeling varnish layer (wax-based) / polyethylene layer (15 μm) / aluminum foil layer (9 μm) / low density polyethylene layer as sealant layer ( 50 [mu] m) [lower side] was produced, and a hermetic seal was produced from this laminated material with a diameter of 90 mm, the full length of the pull-opening piece extending from one end thereof being 210 mm, and the width being 30 mm. Also, as shown in FIGS. 10A and 10B, a circular half-cut 10C for forming an opening at the center of the seal-seal 10 is set to a diameter of 40 mm that is slightly larger than the opening diameter of the funnel 3B. The lower sealant layer was provided about one third of the size from the bottom of the upper paper layer. Further, a half cut 10D was also provided at the boundary between the base end of the drawn-opening piece 101 and the hermetic seal 10 from the lower sealant layer by about one third of the size from below the upper paper layer. Needless to say, the peeling varnish layer is not applied to the inside of the circular half-cut portion provided in the central portion of the seal seal 10 for forming the opening, so that when the pulling opening piece 101 is pulled, From the lowermost sealant layer to the uppermost paper layer of the circular portion surrounded by the half-cut, it is separated and cut from other parts together with the drawn open piece 101 to form an opening.

  In addition, the container main body and the refilling auxiliary member 11 shown in FIGS. 7 to 12 were produced by the same method and means as in Example 1 above.

  Furthermore, the refilling auxiliary member 5 without the gap 7 shown in FIG. 13 was produced by the above method and means.

  Further, a hopper 3 of a type that does not include the flange 3B at the upper end of the ring 3A was manufactured by the above-described method and 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 addition, the peel strength representing the openability of the hermetic seal is about 200 N in Example 1, about 180 N in Example 2, and 100 N in Example 3. In either case, there is no problem with the peel feeling and smooth peeling is achieved. I did it. In addition, although the instant coffee produced by the spray-drying method shows the occurrence of caking when it is exposed to the outside air for a long time, as a result of the test, no caking occurred in any of the examples and there was no problem.

  Further, even in the structure shown in FIGS. 7 to 12, since the parts used are the seal seal 10 and the refilling auxiliary member 11 which are remarkably small in number, it goes without saying that the structure is simple. It was found that manufacturing and processing are very easy, and as a result, it can be provided at a very low price.

  Furthermore, it was found that the extraction opening piece 41 can be smoothly extracted even in the structure shown in FIG.
