Description

  The present invention is a disposable dripper that is set in a cup and used to extract coffee or the like.

  In a disposable dripper that constitutes a filtration bag with a sheet material having water permeability and is set in a cup etc. to extract coffee etc., it is waterproofed as a support to hold the filtration bag on the mouth of the cup A filter bag was attached to the support made of cardboard and the like, and was held on the cup (Registered Model No. 1425541). The type to be placed on the mouth of these cups is above the mouth of the cup. In order to hold the bag portion, the hot water in the cup does not immerse the bottom of the bag portion and has a high drip property, but the support becomes large as a whole, and there are many manufacturing steps and high cost.

  Compared to this, in (Registered Model No. 2505959) and (Japanese Patent Application Laid-Open No. 2004-230143), a support is attached in advance to a belt-shaped sheet material, folded in half in this belt-shaped direction, and this bent side is folded. It is a low-cost type because it is a bag-making type manufacturing method that closes the right side and the upper and lower horizontal sides when positioned in the left vertical direction. The support cannot be extended and attached to the outside, and the support has a smaller configuration than the bag shape. Since the area of the support is small, the bag cannot be configured to be kept high on the cup. Since it is a system that hangs downward from the mouth and stabilizes, the dipping method and the drip method are used in which the lower half of the bag is immersed in hot water in the cup, and the drip of the hot water in the bag is somewhat low.

(Practical Registration No. 1425541) (Practical Registration No. 2565959) (Japanese Patent Laid-Open No. 2004-230143) (Japanese Patent Laid-Open No. 6-113952) (Japanese Patent Laid-Open No. 11-113752) (Japanese Patent Laid-Open No. 2001-314324) 5521)

  (Japanese Patent Laid-Open No. 2004-230143) discloses that the support is developed in a three-dimensional manner, and a locking piece that catches the cup mouth portion with respect to the size of the cup diameter is opened upward and outward in the left and right directions, and has a tensile strength that opens and opens. Since it has no deformation and has a high strength and is greatly extended, the opening angle of the locking piece can cope with the required cup diameter within the required range (Japanese Patent Laid-Open No. 6-133952). There is a problem that the locking piece that catches the side opens to the side and the adaptation range for the size of the cup caliber is small, this is a locking that catches the cup mouth part because the bending strength acts on the locking piece that opens sideways and extends Because the locking piece cannot be extended for a long time and becomes a small extending locking piece, the range of application for the cup caliber is small by changing the opening angle of the locking piece, and the shape of the body of the bag is extended to the left and right. , Ellipse Even when adapting to the size of the cup caliber, the support attached to the bag part extends the locking piece to the side and catches the cup mouth part. Therefore, even if the body of the bag is stretched to the left and right to make it oval, the changing width is small and the adaptation to the size of the cup caliber is small.

  (Registered Model No. 2505959) and (Japanese Patent Application Laid-Open No. 2004-230143) are bagging coffee powder such as when coffee powder is spilled into the cup when the upper mouth portion of the bag portion is smaller than the cup caliber. In Japanese Patent Laid-Open No. 6-133952, there is a point that is difficult to put in, but it is advantageous because it is an inverted conical bag type and has a wide upper mouth, but the locking piece that catches the cup mouth is bent from the support side to the side There is space to extend and catch the cup mouth, and if the size of the upper mouth of the bag is smaller than the cup mouth and the upper mouth of the bag is made larger than the cup mouth, the bag will be stretched upward and configured. There was a problem that the whole became a high center of gravity and became unstable.

  Conventional paper filters and the like (Japanese Patent Laid-Open No. 11-113752) are advantageous at a low cost, but have a problem that requires a lot of work, such as the need to wash the dripper every time it is used.

  The notch provided in the support that catches the mouth of the cup makes it easy to catch the cup mouth, such as rounding or widening the entrance that sandwiches the cup mouth as in JP-A-2001-314324, There is an enlarged version (Act. 7-5521), etc., but the locking parts that are held separately on the left and right sides of the mouth part of the cup are provided with a notch part that catches the mouth part of the cup on both ends. Two locking pieces located on the outer side of the cup mouth as shown in (57-145322) than the complicated set of hands that sandwich the cup mouth into the two notches on one side. It is more convenient to set the cup mouth part between the outer engaging piece and the engaging piece located inside the cup mouth part, which are connected and integrated. 5521) and (Sho 57-145 22) is an operation in which the outer corner of the cup mouth portion is caught within a narrow range between the tip end portion of the inner locking piece and the lower end portion of the outer locking piece, and the inner locking piece is pushed into the cup by hand. The set operation was also difficult.

  A belt-shaped member having a certain width is provided by the water-permeable filter material, and the sheet material is folded in this belt direction and the side that is bent is positioned on the left side. In the present invention, the upper and lower two sides were closed in the conventional bag making method, but in the present invention, the right side and the upper side are not closed, and only one side in the horizontal direction is closed, and at this time, the vertical and horizontal sides are closed. Are the same, and the whole is a regular rectangle. The corner where one side of the closed lower side and the two sides of the bent side touch is positioned downward, and the corner where the upper side and the right side touch is directed upward. In this case, an inverted conical bag shape is formed with the two sides open and the upper mouth of the bag, and the support attached to the sheet material in advance is the back side and the front side of the inverted conical bag part at this time. At this time, the support is mounted horizontally on the outer wall. It is mounting arrangement in the direction.

  The basic form is a bag-making type manufacturing method in which a support is attached in advance to a belt-shaped sheet material, and the three sides of the symmetrical side facing the side folded in two in the belt-like direction and the upper and lower sides are closed. This makes it a low-cost type, and by closing only one side to form a bag shape, the number of manufacturing processes is reduced, increasing production efficiency and reducing costs.

  Conventionally, when coffee powder is put into the bag from the upper mouth of the bag, the mouth of the bag is small and the coffee powder spills into the cup, so the upper mouth of the bag is larger than the cup mouth on the cup mouth. The body of the bag with a planar support on the inverted conical bag portion, the overall shape of the bag is enlarged so that the size of the body portion of the bag at the cup mouth portion occupies the whole inside the cup mouth portion. Hold the cup in the vertical direction so that there is no space in the cup mouth on the left and right outer wall surfaces of the cup, catch the cup mouth, and the bag shape extends upward from the cup mouth due to the inverted conical shape. The upper mouth of the bag is formed on the cup mouth portion at a position where the upper mouth of the bag is low to lower the center of gravity of the bag.

  If the upper mouth of the bag is larger than the cup diameter and the body of the bag is full in the cup, the amount of hot water in the cup cannot be confirmed during the drip, so the two supports attached to the left and right sides of the bag catch the cup mouth. By setting the support body in a shape that is straight and long in the horizontal direction when set, the difference between the curved shape of the cup mouth and the shape of the linear support structure constitutes a clear gap and the hot water surface in the cup Make it easy to check the amount of hot water so that it looks constant regardless of the size of the cup diameter.

  Regarding the adaptability to the size of the cup caliber, the overall shape of the bag is an inverted conical shape, and the shape of the bag is larger at the upper mouth, so even if the upper mouth is made larger than the cup diameter, the lower part of the bag can enter the cup. There is a large inverted conical bag that expands the body size of the bag at the mouth of the cup to the same body as the cup mouth when it is set in a cup. The support body is opened to the left and right, and the bag shape is made from a circle to a circle to widen the width to the left and right, expanding the adaptability to the size of the cup caliber.

  In order to position the lower center of the support inside the cup and the left and right ends on the outside of the cup, the support is provided with a notch opening on the left and right ends to the top and sandwiching the cup opening. The entire support is configured in a flat shape and is held in a direction perpendicular to the cup mouth portion, and the captured support supports the bag portion in the direction of the center of gravity of the bag by the weight in the bag.

  The support body is attached to the outer wall surface of the bag with a mounting portion in which only the central portion penetrates up and down, and the upper end side of the support body is a mouth arm for holding the upper mouth shape of the bag that is wide open As shown in the figure, the mouth arm is formed by cutting the support body into a side that is elongated from the center to the side of the left and right ends, and the lower end of the bag on the left and right sides of the ends of the open sides of the two sides. It is arranged to extend in a curvilinear shape that draws an arc as an axis, and is integrally attached to the outer wall surface of the bag, and a large upper mouth having an inverted conical shape is formed in a circular shape.

  In order to make setting to the cup mouth part easy, both ends of the outer locking piece located outside the cup mouth part are extended long downward by a support body that captures the cup mouth part widely, and the lower ends of the two end parts mutually As an integrated type that is integrally connected, the outer bottom side of the outer locking side is an outer side locking piece that has a wide width as a whole and that forms a lower end side that extends downward at both ends and the center part is recessed to draw an arc. Yes, the inner locking piece is a wide inner locking piece that has left and right cut openings that capture the left and right cup mouths, and the lower side shape is a lower side shape that draws an arc with the center side extending downward, A part of the lower side of the inner locking piece that extends roundly downward and holds the inner side of the cup mouth simply pushes the support body downward just by grasping the inside of the cup mouth, so that the inner locking piece enters the cup mouth and enters the cup It can catch the wall, and the outer locking piece is long downward When the left and right ends are positioned outside the cup mouth and the support itself is pushed downward, the lower side of the outer locking piece is recessed upward toward the center and has an arc. Since the lower side of the cup shape follows the outer corner of the cup mouth, the entire lower end of the outer latch is curved outward and opens, so it is large between the lower inner latch piece. The width that sandwiches the cup mouth part makes it easy to sandwich the cup mouth part. The outer locking piece that makes it easy to catch the outer corner of the cup mouth part and the inside of the cup mouth part is wide. The cup opening can be easily grasped with the inner locking piece that is easy to catch, and the distance between the outer locking piece and the inner locking piece is greatly extended outwardly by extending the outer locking piece downward. The side opens and increases the distance between the inner locking piece and the width direction The cup mouth is easy to catch, and both ends of the outer locking piece are extended downward and the vertical width with the center tip of the inner locking piece is increased. The upper and lower range where the stopper can be captured is expanded so that the cup mouth can be captured in a wide range in three directions: the vertical width, the width direction of the support in the left-right direction, and the width between the outer locking edge and the inner locking piece. It becomes easy to set.

  Conventionally, by the same method as the bag making method that closes the three sides of the symmetric side of the crease side and the two sides in the upper and lower horizontal direction, which is made into a belt-like sheet material having water-permeable filterability, In the present invention, only one side in the horizontal direction adjacent to the crease side is closed, and the corner portion where the closed side and the crease side are in contact is positioned downward, and the other two sides are opened, and an inverted conical bag having an upper mouth. Since the shape is formed, the number of manufacturing steps is smaller than that in the bag making method, and the production efficiency is increased and the cost is reduced.

  When trying to prevent coffee powder from entering the cup when the coffee powder is placed in the bag at the upper opening of the bag that is larger than the cup mouth, the inverted conical bag shape has a high center of gravity on the cup mouth. Since it is not stable to make the upper mouth of the inverted conical bag greatly stretched, the size of the body of the bag at the position of the cup mouth is enlarged to the same size as the cup diameter. By providing a bag portion and attaching and setting a support to the body portion, the upper mouth of the bag larger than the cup mouth portion can be configured at a lower position on the cup mouth portion while ensuring stability.

  Since it is an inverted conical bag portion having the same body portion as the cup diameter at the cup mouth position, the support attached separately to the outer wall surface of the bag body portion at the cup mouth position is left and right. When the body of the bag is a small cup with respect to the size of the cup caliber, the body of the bag is circular and the cup mouth is fully filled. The body part changes to an oval shape, and the left and right supports capture the cup mouth part. At this time, the support body remains flat and the surface of the support body is perpendicular to the cup mouth part. Since the support body has a tensile strength that supports the weight of the bag in the center of gravity of the bag in the direction of the surface of the support body, the support body constitutes a high support force, while Large inverted circular bag shape with the body part occupying the entire inside of the cup mouth By extending to the left and right from the circular shape in the body part, it can be expanded into an elliptical shape and the range to expand the left and right width can be expanded, ensuring the range of adaptation of the cup caliber and supporting body without deformation of the support body It can handle the cup caliber while maintaining a high support strength.

  In order to make the size of the body part of the inverted conical shape occupy the whole inside the cup at the position of the cup mouth part, the support body that holds the bag part and holds the bag part has a planar shape and the surface direction is the cup mouth. The cup mouth part is a notch mouth part that sandwiches the cup mouth part directed from the lower side to the upper side from the lower side of the left and right ends provided on the lower side of the support in the vertical direction with respect to the part. The bag body part can occupy the entire space in the cup mouth part so that no space is taken up in the cup caliber. At this time, the cup inner wall surface is located inside the cup of the support body. The inner locking piece of the support is also in contact with the inner wall of the cup, and when the hot water is poured into the bag containing coffee powder and drip, the hot water inside the cup cannot be seen, so the amount of hot water can be checked. There is no point for this The support that extends to the right and catches the mouth of the cup on both ends is made into a wide and wide support in the left-right direction, and the shape of the straight support and the curved shape of the cup mouth is obtained by catching the cup mouth. A gap is created by the difference so that the hot water surface in the cup can be seen regardless of the size of the cup diameter.

  In order to improve the setability to the cup, the outer locking piece located outside the cup mouth portion of the support is extended downward from the inner locking piece located inside the cup mouth portion. Extending the outer locking piece longer than the front end and extending the lower part of the inner locking piece to the lower end of the outer locking piece, The upper and lower widths of the outer side of the cup mouth on the inner wall surface of the locking piece are enlarged to make it easier to catch the outer corner of the cup mouth. If the corner is caught and the support is lowered downward, the outer locking piece will bend and open at the lower end to widen the space between the inner locking piece and make it easier to catch the cup mouth. The center part of the inner locking piece that extends downward It is an inner locking piece with a lower side shape that draws a downward and wide arc up to both sides that captures the cup mouth located at the left and right as the tip, and the inner wall side of the cup mouth is held wide and caught by the lower side that draws the arc The inner locking piece makes it easier to set because the lower side catches the inside of the cup mouth, and the lower end side of the outer locking piece extends below the lower side of the inner locking piece and the center side is upward The outer locking piece as a whole is formed on the cup mouth by simply lowering the support itself, which positions both ends of the outer locking piece held wide at the outside of the cup mouth. Follow the outer corner and curve outward to open the cup outside, catch the cup outer wall, open between the inner locking piece and the outer locking piece, and open the inner locking piece and the outer locking piece vertically. Cut in a wide range in three dimensions. It is likely to set caught the mouth.
