Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter housing, and more particularly, to a filter housing in which a plurality of filters are stacked and housed in a packaging container.

[0002]

2. Description of the Related Art Conventionally, as a filter container of this type, for example, a container for a coffee filter, a pair of substantially trapezoidal thin pieces are overlapped in the same direction and their upper bases and sides are adhered to each other. An opening is formed on the lower bottom side of the substantially trapezoidal shape. In use, the bag-shaped filter having an opening at the top and having a diameter reduced toward the bottom is folded, so that two substantially trapezoidal paper pieces are folded. The thin flake-shaped storage form is used in a packaging container such as a rectangular paper box or a bag made of a flexible film material which is oriented and laminated in the same direction and stored. When the filter is used, an outlet is opened in the filter container, and the filters are taken out from the outlet. How to take out, for example, by putting or hooking a finger on the surface exposed from the take-out opening of the layer formed by the filter, grasping the edge of the filter,
This filter was pulled out of the outlet through the outlet.

[0003] However, since the filters in the laminating direction in which the thickness in the laminating direction are very thin are densely laminated, fingers can be inserted or caught in order to pick up the filter. The gap between the filters was very small. In addition, since the filters are stacked in the same direction, the vertically adjacent filters are almost in close contact over the entire edge thereof, and there is almost no gap for putting or hooking a finger. Condition. In such a state, even if one of the filters is forcibly grasped, even when a finger is inserted or hooked into the layers of the filters, the edges of the several adjacent filters are also touched. In many cases, there is a problem that it is not hygienic.

Further, even if the end of the target filter can be picked up and pulled, the filter is often made of paper or non-woven fabric having a rough surface. Even when trying to pull out, the fibers on the surface of the filter located above and below it are caught and the upper and lower filters also move in the direction in which they were pulled together, and more than the required number of sheets come out of the outlet. There were many. In such a case, there is a problem that unnecessary filters are discarded without being used, which is uneconomical. Alternatively, several filters are taken out of the packaging container, and a filter that exceeds the required number of them is returned into the packaging container, or another filter that has been pressed out with the required filter by holding the filter layer by hand. , And carefully extract only the necessary filters. However, there is a problem that it is not hygienic to re-contain and use the filter touched by hand in this way.

[0005] In view of such a problem, there has been proposed a filter in which the shape of the filter is devised. For example, as disclosed in Registered Utility Model No. 3044248,
A claw for holding the filter is provided on the inner wall, and a cylindrical container having a raised bottom is accommodated in a cylindrical container having a tongue-like projection formed on a part of the opening edge portion. The filter was lightly fixed in between. The container further includes a lever that is rotationally driven to slide from the tongue-shaped protrusion into the inside of the filter and remove the filter from a region that is held by the claw.
By rotating this lever, only one filter on the outermost layer can be taken out without directly touching it.

[0006] Alternatively, as a filter container which does not use the above-mentioned specially shaped filter, Japanese Utility Model Application Laid-Open No. 63-309 discloses a filter housing.
As disclosed in Japanese Patent Publication No. 26, a bifurcated pinching claw provided at the tip of a fan-shaped plate which is housed in a container and swings around its base in the container is housed in the container by folding it in two. There has been proposed a filter container in which an edge of a fold of a filter is sandwiched and the filter is pushed out of a container through a take-out opening formed in the swinging direction.

[0007]

However, when various functions are added to a packaging container that has been mainly used for packaging, such as the above-described packaging container or a filter container in which the shape of the filter is modified, the packaging container The structure becomes complicated and the size becomes large. Thus, considering the entire container, in order to accommodate the same number of the filters,
There was a problem that extra space was required.
In addition, a complicated process is required to manufacture such a packaging container, and in order for the constituent members to exert their functions, a resin or a resin having a higher strength than a soft material such as a paper box or a resin film is required. It is necessary to use a hard material such as a metal, so that there is a problem that the cost is increased and the weight becomes heavy and it is difficult to carry. Further, the two problems described above, that is, an increase in the size and weight of the filter container, cause a problem that the transportation cost increases when distributing them as products.

[0008] Alternatively, since the packaging container made of the above-mentioned hard material is not disposable but is assumed to be used repeatedly, the filter contained therein is stored in another conventional packaging container at the time of transaction. It is considered that the container is taken out of the container and transferred to a packaging container made of the above-mentioned hard material. Then, there is also a problem that the filter may be touched when the filter is transferred from the packaging container to the container.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a filter housing capable of taking out a filter sanitarily and easily with a simple structure in view of the above-mentioned drawbacks.

[0010]

According to a first aspect of the present invention, there is provided a filter container comprising: a plurality of filters laminated on a package container; A filter in which a set of substantially trapezoidal thin pieces are overlapped in the same direction in the accommodated filter container and their upper bases and sides are adhered to each other, and an opening is formed on the lower base side of the substantially trapezoidal shape. The lower bottom side is closed to form a thin piece into a storage form, wherein the upper bottom of one filter in the storage form and the storage form adjacent to the one filter in the stacking direction. The present invention is characterized in that a filter laminated body in which the lower bottom of another filter is disposed to face and is alternately laminated sequentially is accommodated in the packaging container. In the above-mentioned characteristic configuration, as described in claim 2, an outlet of the filter is opened at an end of the packaging container, and the side of the filter is exposed in a direction exposed from the outlet. It is preferable that the filter container is housed in the packaging container, and further, as described in claim 3, the take-out opening has a width substantially equal to the width of the filter in the housing mode. A rectangular opening formed on the end side of the packaging container, and a cutout portion continuously formed from the center of the rectangular opening toward the center side of the packaging container, It is preferable that a non-slip portion extends from the edge to the outlet between the edge and the outlet.
In addition, as described in claim 4, the packaging container
An opening / closing mechanism for opening and closing the take-out port may be provided, and the opening / closing mechanism may be slidable along an outer surface of the packaging container, as described in claim 5. Preferably, or as described in claim 6, the opening / closing mechanism removes the lid, the housing, one end of the lid, and one end of the housing with the outlet. And a hinge portion connected on a surface side facing the surface provided with the opening, wherein the lid portion turns to a surface side facing the surface on which the outlet is provided and the lid The outlet is opened in a state where the portion and the housing are separated from each other, and the lid is rotated toward the surface provided with the outlet and the lid and the housing are close to each other. Preferably the outlet is closed, or the package is as described in claim 7. A container is formed by opening the outlet in a main body in which both ends of a tubular flexible film are closed, and is formed on an edge of a flexible sealing material having a shape capable of covering the entire outlet. Forming the opening / closing mechanism by disposing the flexible sealing material with respect to the main body so that the bonding surface can be repeatedly bonded and peeled, and the bonding surface can be bonded to the periphery of the outlet. Preferably, furthermore, as described in claim 8, it is preferable that the packaging container is subjected to moisture-proof processing, and further, as described in claim 9, the filter is bonded by pressure bonding. It is preferable that it is formed by molding. And these effects are as follows.

That is, as described in claim 1,
A plurality of filters are stacked, and in a filter container housed in a packaging container, a pair of substantially trapezoidal-shaped thin pieces are overlapped in the same direction, and the upper bases and the sides are adhered to each other,
A filter having an opening formed on the lower bottom side of the substantially trapezoidal shape,
When the lower bottom opening is closed and formed into a flake shape to be in a storage form, the volume per filter becomes small,
In addition, since unevenness is reduced, lamination becomes easy. Then, instead of stacking the filters of this storage mode with all being oriented in the same direction, the upper bottom of one filter in the storage mode, and the storage mode adjacent to the one filter in the stacking direction. The lower bottom of some other filter,
When the layers are opposed to each other and are alternately stacked, the edge portion surrounded by the lower bottom and the side that intersects the lower base intersects the upper base of the filter vertically adjacent to the filter in the stacking direction of the filter. The filter laminate is formed so as to partially protrude from an edge formed by the side. That is, an edge portion surrounded by the lower base and a side crossing the lower base protrudes from the stacking surface of the filter stack as a projection for picking up with a finger. Above and below this projection, the vertically adjacent filter plays the role of a spacer, and is vacant by the thickness of one filter. Since it becomes easy to pick up, the operability is also improved. In addition, since it is difficult for a finger to touch an adjacent filter, hygiene is excellent. In addition, in order to accommodate the filter laminated body in which the filters are laminated in a packaging container, it is sufficient that the outlet is large enough to allow the filter to pass therethrough. For example, a packaging container having the simplest conventional shape, that is, a packaging container that can be used as a packaging / storage container and that can form an outlet can be used. Further, in particular, a packaging container such as a box body such as a rectangular body or a bag of a substantially cylindrical resin film is symmetrical in both the major axis direction and the minor axis direction. If it has a volume and a shape that can be accommodated only by itself, the coffee
It can also be accommodated in a direction. Therefore, as the packaging container used in the present invention, a conventional simple-shaped packaging container can be used as it is, and even if the same number of filters are accommodated in a packaging container having the same volume, the filter according to the present invention can be used. In the container, since the interval between the filters in the portion picked up by the finger is doubled, it is very easy to take out the container. In addition, the filter container according to the present invention has almost the same handling as the conventional filter container having a simple-shaped packaging container, so that the handling is easy, the storage space is small, and the cost of transportation and the like is low. Can be held down.

Further, in the above-mentioned characteristic configuration, an outlet of the filter is opened at an end of the packaging container, and the side of the filter is opened from the outlet. When the package stack is accommodated in the packaging container in a direction where the side is exposed, the area where the direction of the pair of filters oriented in the normal and reverse directions has been switched, that is, one side from the stacking surface of the filter stack. The protruding edge of this filter and the protruding edge of the other filter facing this protrude outward from the outlet. Then, since these protruding edge portions protrude outward from the outlet, they can be easily hooked or pinched, and the other portions remain in the packaging container. Therefore, external contact including a finger can be suppressed, and operability and hygiene are improved.

Further, as described in claim 3,
If the outlet is a rectangular opening formed at the end of the packaging container over substantially the same width as the width of the filter in the storage mode, the filter is less likely to be clogged at the outlet, and , And slide it in the packaging container to facilitate removal. And further, by providing a cutout portion that is continuously formed from the center of the rectangular opening toward the center of the packaging container,
When the filter is picked up or picked up, it is possible to pick up or change the direction of the filter to a portion exposed from the cutout portion, thereby improving operability. Further, if a non-slip portion extends from the edge to the outlet between the edge of the end and the outlet, the same filter can be used when gripping and pulling out the filter. Other laminated on the laminate,
In particular, it is possible to prevent the lower filter from protruding in the same direction and popping out, or to prevent the filter constituting the filter laminate from sliding out without permission when the packaging container is inclined.

Further, if the packaging container is provided with an opening / closing mechanism for opening / closing the take-out port, as described in claim 4, except when necessary such as when taking out the filter, Since it is possible to suppress the filter from coming into contact with the outside and to prevent the filter from suddenly popping out, it is hygienic and easy to handle.

Here, as described in claim 5,
When the opening / closing mechanism is a cylindrical body slidable along the outer surface of the packaging container, the opening / closing mechanism has a simple configuration and can be easily created. With advantages.

Alternatively, as described in claim 6,
The opening and closing mechanism is formed by a lid, a housing, and a hinge that connects one end of the lid and one end of the housing on the back side of the mantle container, The lid is pivoted to the rear side to open the take-out opening in a state where the lid and the housing are separated from each other, and the lid is pivoted to the front side of the mantle container and the lid is rotated. Even if it is configured to close the take-out port in a state in which the container and the storage portion are close to each other, there is an advantage in terms of hygiene and handling as described above.

Further, as described in claim 7, the packaging container 2 is formed by opening both ends of a tubular flexible film in a main body in which both ends are closed with the take-out opening. In this case, since the shape of the filter container can be easily changed, the filter container is deformed according to the shape of the storage space, or when the number of stored filters is reduced, the packaging container 2 is bent to form the filter stack. The volume can be adjusted to the volume of the body, and the volume can be easily reduced. This makes transport and storage even easier. Further, an adhesive surface that can be repeatedly adhered and peeled is provided on an edge of the flexible sealing material having a shape capable of covering the entire outlet, and the adhesive surface can be adhered to a peripheral portion of the outlet. When the flexible sealing material is disposed on the main body to form the opening / closing mechanism, it is possible to prevent the filter from contacting the outside unless necessary. The structure of this opening and closing mechanism is as follows:
Substantially, only a thin flexible sealing material is coated along the surface of the packaging container 2, so that the size of the packaging container 2 or the filter container is hardly increased.
It does not prevent volume reduction.

Further, when the packaging container is subjected to a moisture proofing process, the filter contained in the packaging container can be prevented from absorbing moisture, so that coffee can be prevented. Can be maintained for a long time, can be prevented from being deformed, and the propagation of microorganisms can be suppressed.

If the filter is formed by pressure bonding, small irregularities are formed on the bonding surface and the periphery. When the filters are stacked in the same direction, the small irregularities are in close contact with the corresponding concave and convex portions of the vertically adjacent filter, so that the thickness between the filters reflects the thickness of the filter in the laminating direction. Has little effect. However, as described in claim 9, when the orientation of the vertically adjacent filter is different, the small unevenness is placed at a position different from the unevenness of the vertically adjacent filter, and the concave portion has an amount corresponding to its bulk. Only the adjacent filters will be pushed up. Then, although a little,
The thickness between the filters is increased, so that operability is further improved when a finger is inserted or hooked. As a filter formed by pressure bonding, a general-purpose filter, that is, a fan-shaped filter base paper whose arc is substantially semicircular, is folded in half to form two layers, and the bottom side (top of the trapezoidal shape) is formed. A portion corresponding to the bottom) and a portion corresponding to the side portion are continuously pressed, and a bag-shaped filter having an open upper end can be used.

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.
An example in which the filter is a coffee filter for extracting coffee liquid from roasted coffee particles and filtering the coffee liquid from the roasted coffee particles will be described with reference to the drawings.

As shown in FIG. 1A, a filter container as a filter container according to the present invention is a filter laminated body 1 in which filters (coffee filters) 11 are laminated.
Is housed in a substantially rectangular packaging container 2. Specifically, the filter 11 constituting the filter laminate 1
As shown in FIG. 1 (a), a pair of substantially trapezoidal thin pieces are overlapped in the same direction, and their upper bottoms 11c and a pair of side edges 11d are adhered to each other. A filter having an opening formed on the bottom 11b side is closed and the opening on the lower bottom 11b side is formed into a flake shape to be housed. Then, the upper bottom 1 of one filter 11 in the accommodation mode
1c and the lower bottoms 11b of the other filters 11 in the accommodation form that are adjacent to the one filter 11 in the stacking direction and are alternately stacked so as to face each other, that is, the lower part of the one filter 11 The filter stack 1 is formed by alternately arranging and stacking the bottom 11b and the upper bottom 11c of another filter 11 adjacent to the one filter 11 in the stacking direction so as to overlap. The filter laminate 1 thus laminated has substantially the same bulk or a slightly higher bulk than the case where the same number of filters 11 oriented in one direction are laminated, for the reason described later.

When the filter laminate 1 is viewed from the laminating surface, an end 11e separated by a lower bottom 11b and a side 11d of the filter 11 laminated in the forward and reverse directions is formed by the lower bottom 1e.
1b and appear alternately and symmetrically with respect to a line connecting the midpoints of the upper base 11c. In other words, there is a space below and above the end 11e by the volume of one filter 11.

Here, as shown in FIG. 4 (a), the filter 11 is preferably formed by folding a filter base paper having a semicircular arc into two halves, and forming a substantially trapezoidal thin piece into two pieces.
Ends of the upper base 11c of this substantially trapezoidal shape and a pair of side edges 11d of the two pairs of side edges 11d.
And a side edge 11 corresponding to an edge of the filter base paper.
The end portions d are continuously bonded by pressure bonding to form a bag having an open lower bottom. By applying this pressure bonding, as shown in FIG. 4 (b), fine and very small irregularities 11f and 11g are formed on the end of the upper bottom 11c and the end of one side 11d. Are formed in large numbers. Since the unevenness is formed by pressure bonding, the concave portion 11f viewed from the front corresponds to the convex portion 11g on the back surface, and the convex portion 11g slightly rises at least with respect to one surface of the thin piece, and becomes bulky. . Therefore, if the filters 11 having the slightly higher bulk of the side 11d are stacked in the normal and reverse directions, the end portion 11e will have the convex portion 11g in addition to the bulk of the adjacent filter 11. At intervals of the bulk of
By protruding from the side surface of the filter stack 1 and putting a finger on it, the end 11e can be easily grasped.

The end of the packaging container 2 has a take-out port 2
1 is provided, and preferably, a rectangular opening 21a formed on the end side of the packaging container 2 over substantially the same width as the width of the filter 11 in the storage mode, and a center of the rectangular opening 21a. And a cutout portion 21b formed continuously from the portion toward the center of the packaging container 2. In addition, between the edge of the end and the rectangular opening 21a of the outlet 21, the rectangular opening 2
A non-slip portion 22 extends toward 1a, and serves to prevent the filter 11 accommodated in the packaging container 2 from unexpectedly slipping out of the packaging container.

The filter laminate 1 laminated as described above
As shown in FIG. 1A, when the container 11 is stored in the packaging container 2, the side 11 d side is exposed to the outlet 21, that is, the end 11 e is positioned on the outlet 21 side. To accommodate. When the filter stack 1 is accommodated in the packaging container 2 in this manner, the end 11e of the filter 11 is exposed from the rectangular opening 21a, and is hooked with the fingertip 4 (FIG. 2A). (See FIG. 2 (b)), and can be pulled out of the packaging container 2 (see FIG. 2 (c)). The notch 21 is located below the rectangular opening 21a.
When b is provided, as shown in FIG. 2B, when the filter 11 is picked up or picked up,
The end 11e of the filter 11 is
Can be touched or bent to the exposed portion, and can touch a wider range of the end portion 11e as compared with the case where the notch portion 21b is not provided, so that the operability is good.

Further, the filter container according to the present invention may include an outer box 3 having substantially the same shape as an opening / closing mechanism for opening and closing the outlet. For example, the outer box 3 is shown in FIG.
As shown in (a), the substantially rectangular front and rear walls 34, 35
And a substantially rectangular packaging container comprising left and right side walls 36, 37 and upper and lower side walls 38, 39, wherein the front wall 34
, The two ends of the front cleavage line 41 formed on the rear wall 35
The left and right side cleavage lines 42 and 43 connecting the both ends of the hinge 33 formed of the bent curve formed on the left and right side walls 36 and 3 respectively.
7 can be formed. A perforation is formed between the front cleavage line 41 and the left and right cleavage lines 42 and 43 so that the front cleavage line 41 and the left and right cleavage lines 42 and 43 can be easily opened. The filter housing is opened, and the upper side wall 38 side of the outer box 3 separated by the hinge 33 from the front cleavage line 41 and the left and right side cleavage lines 42 and 43 is the lid part 32 and the lower side wall 39 side is the storage part. It becomes 31. When the lid 32 is rotated toward the rear wall 35 around the hinge 33, FIG.
As shown in (b), an opening 44 is formed in a portion surrounded by the front cleavage line 41, the left and right cleavage lines 42, 43, and the hinge 33, and the filter 11 is accommodated from the opening 44. The outlet 21 of the packaging container 2 is configured to be exposed. At the time of non-use, if the cover 32 is rotated toward the front wall 34, the opening 44 is closed, and the filter 11 comes into contact with the outside or unexpectedly slides out of the outlet 21 of the packaging container 2. Can be prevented.

Alternatively, as shown in FIG. 1 (a), the filter container is formed in a cylindrical outer box 3 having substantially the same shape as the packaging container 2 and having openings in the surfaces corresponding to the upper and lower side walls.
So that the packaging container 2 can be inserted into the outer box 3 so as to be slidable in the vertical direction. With this configuration, when not in use, the packaging container 2 is housed in the outer box 3, the take-out port 21 is closed, and the filter 11 comes into contact with the outside or the packaging container 2 Can be prevented from slipping out of the outlet. Further, at the time of use, the packaging container 2 can be slid with respect to the outer box 3 so that the outlet 21 can be easily exposed.

[Another Embodiment] Another embodiment will be described below. (1) The packaging container 2 may be made of a material other than paper as long as the material is inert to the filter. For example, a light and easy-to-handle resin film may be used. (2) Both the packaging container 2 and the outer box 3 described above can be subjected to waterproof processing, whereby the filter 1
1 can suppress moisture absorption. The waterproofing method is to cover the paper constituting the packaging container 2 or the outer box 3 with a waterproof film, or impregnate the paper constituting the packaging container 2 or the outer box 3 with a resin to form a water-repellent layer on the surface. Or the packaging container 2
The outer box 3 may be made of a water-impermeable resin film. Further, the waterproofing process may be performed only on the inner surface of the packaging container 2 to waterproof the area closest to the filter 11 without waterproofing the entire packaging container 2 or the outer box 3. (3) The packaging container 2 does not need to be a fixed shape like a container made of paper or the like, and may be an irregular shape. For example, both ends of the tubular flexible resin film are closed by heat fusion or bonding with an adhesive to form a main body of the packaging container 2, and an outlet through which the filter can pass is provided on the upper surface side of the main body. May be formed. With this configuration, the shape of the filter container can be easily changed, so that the filter container is deformed according to the shape of the storage space, or the packaging container 2 is bent when the number of stored filters is reduced. Thus, the volume can be adjusted to the bulk of the filter laminate, and the volume can be easily reduced. This makes transport and storage even easier. The above-mentioned irregular-shaped filter container preferably further includes the opening / closing mechanism. For example, the packaging container may be a band-shaped or plate-shaped flexible sealing material having an adhesive surface that can be repeatedly adhered and separated. The outlet of the container 2 and its peripheral part, if necessary, may be completely covered so as to prevent contact between the filter and the outside unless necessary. More preferably, the adhesive surface is arranged at a position corresponding to a peripheral portion of the outlet when the flexible sealing material contacts the main body in order to avoid contact with the filter.
Further, if a protrusion not provided with the adhesive surface is extended at one end of the flexible seal material so that the flexible seal material can be turned up by grasping the protrusion, the take-out opening is provided. Can be easily opened. (4) The outlet 21 may be opened from the beginning, but a perforated line may be provided on a portion corresponding to the outer periphery of the outlet 21 so that the perforated line can be broken and opened when necessary. By doing so, the contact between the filter 11 and the outside can be prevented until necessary. (5) Although the case where the filter is a coffee filter has been described as an example, the use of the filter is not limited to the coffee filter, and is used, for example, for extracting and filtering tea products such as black tea, oolong tea, and green tea. Or it may be used for filtering soup stock. (6) The filter used in the present invention exhibits a liquid / solid holding function and a filtering function as the above-described filter, and a set of substantially trapezoidal thin pieces is overlapped in the same direction to form an upper base. A filter in which an opening is formed in the lower bottom side of the above-described substantially trapezoidal shape by adhering each other and sides to each other can be formed into a flake shape by closing the opening in the lower bottom side so that the filter can be housed. For example, the shape is not limited to the shape shown in FIG. For example, two substantially trapezoidal filter flakes of the same shape are superimposed in the same direction, and are continuously formed along the edges of the corresponding upper bases and both sides, that is, three sides excluding the lower base. A bag-shaped filter that is adhered and has an opening formed on the lower bottom side of the substantially trapezoidal shape may be used. In this case, when the opening on the lower bottom side of the filter is closed, the filter becomes a flake shape, and can be housed.
