Description

The present invention relates to collapsible cups.

Paper or plastic resin cups are used as disposable cups for temporary use. The mouth is usually circular, and the overall shape is an inverted truncated cone or cylinder. When storing and carrying multiple disposable cups, the cups are stacked inside and outside. At present, the shape of the cup does not change and remains as it is, so when storing and carrying it, it is necessary to secure a space equivalent to the volume of at least one cup.

Japanese Utility Model Application No. 61-179259 (Japanese Utility Model Application No. 63-86011) Japanese Patent Application No. 2003-287188 (Japanese Patent Application No. 2005-22753) Japanese Patent Application No. 2003-291848 (Japanese Patent Application No. 2005-29249)

Types of cups include glass, ceramic, metal, wood, plastic resin, paper, etc. Disposable cups for temporary use are mainly made of paper or plastic resin. be. On the market, there are bellows-type expandable cups made of silicone, but silicone requires a certain thickness and does not become completely flat even when folded. In addition, it is not disposable because it can be washed and used repeatedly.

It is required that items used for mountain climbing, camping, etc. do not become luggage as much as possible and do not take up much space. If you use a reusable cup over and over without washing it, bacteria will grow, and depending on the type of drinking water that contains sugar, it may become sticky or leave an odor. is sometimes useful. Moreover, in the event of a disaster, it may be difficult to use water, so the frequency of using disposable cups will increase.

In highly public places, it is preferable to use disposable cups when providing beverages such as tea and cold water at drink servers from the viewpoint of preventing infectious diseases such as viruses and bacteria.

When carrying it inside a bag or rucksack when going out, it is currently carried in the shape of a cup, so it requires a minimum space equivalent to the volume of one cup or more, and the space is limited. occupy part of the Disposable cups made of paper or plastic resin are thin and soft, so if you carry them with a lot of luggage or heavy luggage, there is a risk that the cup body will be crushed if you put it in a bag or backpack. be.

In the case of a retractable cup, the number of stages that can be contracted and expanded inevitably increases due to the complexity of the structure and the increase in the number of manufacturing processes, which inevitably increases the manufacturing cost. In addition, it is not disposable because it is made on the premise of reuse. Furthermore, the weight of a single cup is necessarily increased when compared to disposable cups. Further, in the case of an extendable cup, when it is shrunk and folded, it does not become completely flat when stored, but becomes thicker because it has a cubic or rectangular parallelepiped shape.

Disposable collapsible cups have been used for a while after the transition from the days of Japanese National Railways to passenger railway companies. Envelope-shaped paper cups, which were used as utensils, are widely known. This cup is formed in the shape of an envelope-shaped three-sided bag, and has an ideal shape as a folding cup that is completely flat when stored. However, since the shape of the cup is very unstable when filled with water, in order not to spill the water in the cup, always hold both sides of the cup and hold it with your hands while trying to maintain a certain shape. I had to have it.

Considering the recent carbon dioxide emission reduction, resource saving, waste plastic problem, etc., it is not necessary to limit it to disposable, but it is made of plastic resin or water resistant paper, and it can be reused. Of course it is one of the options.

In order to solve all of the above problems, the present invention reduces the storage width when folded at the time of storage, and makes it possible to store more compactly. An object of the present invention is to provide a plastic resin cup.

The collapsible cup according to the present invention has a rectangular prism shape in the main portion for containing liquid in the unfolded state in use, and a rhombic or square cross-section of the mouth portion in drinking. The shape of the main portion for drinking is elliptical or cylindrical, and the cross section of the mouth portion during drinking is elliptical or circular.

In addition, the reverse tapered type, which is similar to a normal cup, can be applied to each of the square prism shape and the elliptical or cylindrical shape.

In the quadrangular prism-shaped folding cup according to the present invention, of the four vertices on the upper part, two apexes that are not suitable for drinking, which are located at the sealing portions on both sides of the cup, are removed. Except for this, the remaining two opposing vertices are used as drinking holes.

In addition, in the elliptical cylindrical or cylindrical folding cup according to the present invention, except for a part of the circumference of the two non-drinkable portions located at the sealing portions on both sides of the cup, As with a normal cup, the edge of any portion of the circumference is used as a drinking spout.

The basic shape and structure of the folded cups of both shapes according to the present invention when formed and folded is a structure in which the cup-forming sheet is folded in two at the center, and joints are provided on both sides of the cup. It is composed of a portion of the seal location.

A folding cup according to the present invention is formed by the following method.

The folding cup according to the present invention is in a completely flat state when folded, and changes from a bag-like shape to an unfolded state when the cup is drunk. In order to be able to do this, it serves as a guide for folding, and is preliminarily placed in the central portion of the cup-forming sheet by pressing the crease with the prescribed unevenness related to the formation of the cup. All of this is carried out before pressure bonding for forming the cup body. Mountain folds are convex, valley folds are concave, and each fold is pressed. This fold press is the cornerstone of the folding cup according to the present invention, and serves as a guide when assembling and forming the cup. It is a part. This crease will also simultaneously form the bottom surface of the bottom of the cup and the drinking surface of the top of the cup.

A quadrangular prism-shaped folding cup according to the present invention will be described. Paper rolls made from paper or plastic resin, or plastic roll resin, either before or after cutting into rectangular or square cup-forming sheets of the specified size for forming cups. With the 1/2 center of the sheet in the longitudinal direction and the position where the sheet is folded and bent in two as the reference line, the line is the axis of symmetry, and the isosceles triangle or the isosceles right triangle is linearly symmetrical, that is, the entire A crease forming a rhombus or square is placed in the central portion of the sheet, which is used as the bottom surface of the cup. Further, a folding position for forming a quadrangular prism-shaped folding cup, in which a crease that forms a mountain fold is added to the outer side of the cup in the longitudinal direction from the center of the short side direction of the sheet, and the crease is used as the unfolded position. , resulting in a crease with a drinking spout. The standard shape of the base of the bottom of the cup is rhombus, and as the area of the bottom of the bottom of the cup and the area of the mouth of the cup are increased, the rhombus gradually approaches a square, and the upper limit of the formable shape is becomes a square.

After making a crease that becomes a valley fold toward the outside of the cup in the boundary line between the sealing portion in the longitudinal direction of both ends of the cup-forming sheet, the sheet is folded in two facing each other and pressure-bonded. Just by doing so, the folding cup is completed.

At the same time, it can be folded flat into a rectangular or square shape, and when drinking, both rhomboidal and square shapes are formed from the sealed portions at both ends after pressure bonding toward the center of the cup mouthpiece. , so that the shape of the central part forms a rhombus or square, it is folded with equal force from both the left and right directions, and finally the rhombus or square that is the bottom of the bottom of the cup is folded into the same rhombus or square as the crease By folding back the same shape from the outside of the cup to the inside of the cup along the crease, the part for containing the liquid is formed in the shape of a quadrangular prism, and the cup is assembled.

That is, the shape of the rhombus or square that forms the base of the bottom of the cup placed in the center of the cup-forming sheet also becomes the shape of the drinking spout. In addition, when the area of the bottom surface of the bottom of the cup is greatly increased, the area of the mouth of the top of the cup is also increased proportionally.

Next, an elliptical cylindrical folding cup according to the present invention will be described. Paper rolls made from paper or plastic resin, or from plastic roll resin, into rectangular or square cup-forming sheets of specified size for forming cups, either before or after cutting the sheets. With the center of 1/2 in the longitudinal direction and the position where the sheet is folded in half and bent as a reference line, a semi-ellipse or semi-circle, that is, an ellipse or a circle, which is symmetrical about the line, is formed. Place the crease in the center of the sheet and use it as the bottom of the cup. The standard shape of the base of the bottom of the cup is elliptical, and as the area of the bottom of the cup and the area of the mouth are increased, the ellipse gradually approaches a circular shape, and the upper limit of the shape that can be formed is becomes a square.

After making a crease that becomes a valley fold toward the outside of the cup in the boundary line between the sealing portion in the longitudinal direction of both ends of the cup-forming sheet, the sheet is folded in two facing each other and pressure-bonded. Just by doing so, the folding cup is completed.

At the same time, it can be folded into a flat state with a rectangular or square shape when it is folded, and when drinking, both elliptical and circular shapes are directed from the sealed portions at both ends after pressure bonding to the center of the drinking mouth of the cup. Then, it is bent toward the center with equal force from both the left and right directions so that the shape of the central portion forms an ellipse or circle. By folding the cup along the crease in the same shape from the outside so that it has the same elliptical or circular shape as the crease, the portion for containing the liquid is formed into an elliptical or cylindrical shape, thereby making the cup. Assembled state.

That is, the elliptical or circular shape of the bottom surface of the cup placed in the center of the cup-forming sheet also becomes the shape of the drinking spout. In addition, when the area of the bottom surface of the bottom of the cup is greatly increased, the area of the mouth of the top of the cup is also increased proportionally.

Folding cups in the shape of a quadrangular prism are cut from roll paper or plastic roll resin made from paper or plastic resin into rectangular or square cup-forming sheets of the specified size related to the formation of the cup, and the sheets are At 1/2 position of the longer side of the rectangle or one side of the square, a crease is made parallel to the short side or one side of the rectangle in the shorter direction of the same sheet as a folding point of the cup. . In addition, at the position where the long side of the rectangle in the longitudinal direction of the sheet or the center of one side of the square is divided into two, when the sheet is folded in two at the same position, this fold line is the axis of symmetry. A line-symmetric isosceles triangle or right-angled isosceles triangle across both contiguous cylindrical walls and side surfaces, and the overall shape of the base of the bottom of the cup when in use forms a diamond or square crease. . When folded, if the shape of the base of the bottom of the cup is rhomboid, it will be an isosceles triangle that is symmetrical with the axis of symmetry on the longer diagonal of the folding point, and if it is square, the folding point will be are divided into isosceles right triangles having line symmetry with the diagonal line of the line as the axis of symmetry. In other words, it becomes an isosceles triangle or a right-angled isosceles triangle that is line-symmetrical at the folding point. This portion is for forming the bottom surface of the bottom of the cup when unfolding from the folded state and drinking. In the unfolded state, the shape of the bottom of the cup when viewed from the vertical direction is a rhombus or square. About 1/6 to 1/12 of the short side or one side of the rectangle in the short direction of the sheet is attached to both ends of the long side of the rectangle in the longitudinal direction or one side of the square of the same sheet. A margin for sealing is provided in the width of the range, and a crease is made to form a part of the side surface of the quadrangular prism that accommodates the liquid when the cup is unfolded. In the short side of the rectangle in the short direction of the sheet or half of one side of the square, folds are made to form a part of the side of the square prism when unfolding for drinking, The upper side of this crease is used as a mouthpiece.

In the next step, the glue margin portions of the sealed portion of the cup-forming sheet that has been divided into two parts are folded in two facing each other and pasted together for pressure bonding, and one cup-forming sheet is folded in half in two. Keep it folded. As a result, the folding cup according to the present invention is completed in the folded state, and this state becomes the state at the time of shipment from the factory.

Cylindrical folding cups are made by cutting roll paper made from paper or plastic resin or plastic roll resin into a rectangular or square cup-forming sheet of the specified size related to the formation of the cup, and then At half the length of the long side of the rectangle or one side of the square, there is a crease as a cup folding point that is parallel to the short side of the rectangle in the width direction of the same sheet or one side of the square. put in. In addition, at the position where the long side of the rectangle in the longitudinal direction of the sheet or the center of one side of the square is divided into two, when the sheet is folded in two at the same position, this fold line is the axis of symmetry. It has a line-symmetrical semi-elliptical or semi-circular shape across both connecting cylindrical walls and side surfaces, and the overall shape of the bottom surface of the bottom of the cup when in use forms an elliptical or circular crease. When folded, the shape of the bottom of the bottom of the cup is elliptical, semi-elliptical with line symmetry with the major axis of the folded part as the axis of symmetry, and the same circular shape is the diameter of the folded part are arranged in a line-symmetrical semicircular shape with the . This part is for forming the bottom surface of the bottom of the cup when it is unfolded from the folded state and used. In the unfolded state, the bottom of the cup has an elliptical or circular shape when viewed from the vertical direction. About 1/6 to 1/12 of the short side of the rectangle in the longitudinal direction of the sheet or one side of the square on both sides of the long side of the rectangle of the same sheet or one side of the square A glue margin is provided with a certain width, and a crease is made here to form the side part of the elliptical cylinder or cylinder that stores the liquid when the cup is unfolded, and the upper part of this crease part is used as a mouthpiece.

In the next step, the glue margin portions of the sealed portion of the cup-forming sheet that has been divided into two parts are folded in two facing each other and pasted together for pressure bonding, and one cup-forming sheet is folded in half in two. Keep it folded. As a result, the folding cup according to the present invention is completed in the folded state, and this state becomes the state at the time of shipment from the factory.

The folding cup in the shape of a quadrangular prism, in the unfolded state at the time of drinking, has the opening and bottom of the cup at the top and bottom bottom portions in the vertical direction of the quadrangular prism forming a rhombus or square, and four cylindrical walls. It consists of side surfaces and is assembled to form a rhombic or square tubular shape as a whole.

As for the method of unfolding the folding cup in the shape of a quadrangular prism, hold the two seal points on both sides of the cup near the opening of the top of the cup with both hands, and spread it evenly from both the left and right sides toward the center of the cup on the drinking mouth side. With the force of , push the cup to the extent that it forms a rhombus or square in the center of the cup so as to be pulled together from the direction of the seal points on both ends. Next, the cup body is fixed, and on the side opposite to the opening side, the center part that constitutes the bottom part of the square prism, which is also the folding part of the cup and the bottom surface that becomes the bottom of the cup, is attached to the cup. The bottom surface of the bottom of the cup is formed by folding the central portion of the diamond or square along the crease into a diamond or square toward the interior containing the inner liquid. When the bottom surface of the bottom of the cup is folded back inside the cup, the shape of the bottom surface of the bottom of the cup is fixed, and at the same time, the cylindrical wall and side surface on the mouth side, that is, the side surface of the square prism are also fixed. This is because the area of the bottom surface of the bottom of the cup is the same as when it was folded, so by folding it back in the opposite direction, lateral pressure is applied to the cylindrical wall and the side surface, and the crease shape of the bottom of the bottom of the cup to be formed is the shape of the cup. This is because the bottom surface of the bottom of the is to be fixed. Here, a drinking mouth having the same size as the rhombus or square formed on the bottom surface of the cup is formed on the bottom surface on the opposite side of the square prism. The rhombic or square shape fixed to the bottom surface of the cup ensures a certain volume in the cup, allows the liquid to be stored in the cup in a stable state, and stabilizes the overall shape of the cup. It can be maintained continuously.

An elliptical cylinder or cylindrical collapsible cup, when unfolded during drinking, has an elliptical opening on one side of the upper and lower bottom surfaces of the elliptical cylinder or cylinder, and the bottom part is elliptical or It has a circular shape and is composed of side surfaces that are also cylindrical walls at two locations, and is assembled to form an elliptical or circular cylindrical shape as a whole.

This is a method of unfolding an elliptical cylinder or cylindrical folding cup. Pick up two seal points on both sides near the opening side of the upper part of the cup with both hands and move it in both left and right directions toward the center of the drinking mouth side of the cup. With an equal amount of force, the cups are pushed together from the directions of the seal points on both ends to the extent that an oval or circular shape is formed in the center of the cup. Next, the cup body is fixed, and the central portion constituting the bottom portion of the elliptical cylinder or cylinder, which is the folding part of the cup and the bottom surface that is the bottom of the cup at the opposite side to the opening side, The elliptical or circular central portion is folded along the crease into an elliptical or circular shape toward the liquid containing interior of the cup to form the base of the bottom of the cup. When the bottom surface of the bottom of the cup is folded back inside the cup, the shape of the bottom surface of the bottom of the cup is fixed, and at the same time, the cylindrical wall and side surface on the drinking mouth side, that is, the side portion of the elliptical cylinder or cylinder is also fixed. This is because the area of the bottom surface of the bottom of the cup is the same as when it was folded, so by folding it back in the opposite direction, lateral pressure is applied to the cylinder wall and the side surface, and the fold shape of the bottom of the bottom of the cup to be formed is the shape of the cup. This is because the bottom surface of the bottom is to be fixed. Here, the lip of the same size as the ellipse or circle formed on the bottom surface of the cup is formed on the portion of the bottom surface on the opposite side of the elliptical cylinder or cylinder. The rhombic or square shape fixed to the bottom surface of the cup ensures a certain volume in the cup, allows the liquid to be stored in the cup in a stable state, and stabilizes the overall shape of the cup. It can be maintained continuously.

In addition to square prismatic, elliptical prismatic or cylindrical folded cups, cups of each shape can also be formed, such as those having an inverse tapered shape close to the shape of a general cup. The position where the cup-forming sheet for two symmetrical isosceles trapezoids sharing the upper base portion of the reverse tapered isosceles trapezoid is divided into two halves at the center of the longitudinal direction as the folding point of the cup. , with the folded portion as a reference, the upper base portion of the isosceles trapezoid is a common axis of symmetry, and two axisymmetric isosceles trapezoids are arranged facing each other. When the sealing part is pressure-bonded, the upper base part of the isosceles trapezoid is folded, and the two line-symmetrical isosceles trapezoids are integrated into one, and both ends of the isosceles trapezoid become the two sides of the cup. The glue margins, which are the sealing portions of the cup-forming sheets provided on the legs of the cup-forming sheet, are folded in two facing each other and adhered together to perform pressure bonding, and one cup-forming sheet is folded in half and folded. state. As a result, the folding cup having the reverse tapered shape according to the present invention is completed in the folded state, and this state becomes the state at the time of shipment from the factory. Folding cups having an inverse tapered shape can be formed into three types: a square prism, an elliptical cylinder, or a cylindrical cylinder. In addition, in the case of the folded cup having the reverse tapered shape, since the cup-forming sheet cannot be composed only of straight lines, the edge of the cup-forming sheet is slightly lost, so it is necessary to devise the cutting method and cutting shape. be.

The rectangular, elliptical, or cylindrical collapsible cup according to the present invention cannot be placed independently on a grounded surface such as a desk or table without holding hands. Therefore, a pair of small individual pieces forming a pair of rectangles about 1/4 to 1/5 of the height (longitudinal width) of the cup are placed below the sealing portion, which is the pressure-bonded portion on both sides of the cup. A leg sheet for a leg-opening type cup is formed separately, and has a crease that divides the longitudinal direction of the leg sheet into three equal parts, and sandwiches the lower two places of the sealing parts on both sides of the cup. The above problems can be solved by performing pressure bonding as shown in FIG.

In addition, the inverted tapered rectangular, elliptical, or cylindrical folding cup according to the present invention cannot be placed independently on a ground surface such as a desk, table, or the like. Therefore, at the lower part of the sealing part, which is the pressure-bonded part on both sides of the cup, a pair of inverted V-shaped letters of the alphabet about 1/4 to 1/5 of the height (longitudinal width) of the cup is formed. A pair of small, individually formed open-leg cup leg sheets are separately formed, and have folds that divide the length of the same leg sheet into three equal parts, which are attached to the sealing points on both sides of the cup. By performing pressure bonding so as to sandwich the lower two places and adding a small leg that can be spread in parallel with the ground surface in the shape of the letter Y or T, the above problem can be solved in the same way. be done.

In addition, it is possible to form the leg portions in different ways. When forming the folding cup in the shape of a square prism, elliptical cylinder or cylinder according to the present invention, widen the width of the sealed portions at both ends of the cup, and vertically extend the cup at the central portions of the sealed portions on both sides. Approximately 1/3 to 1/2 of the length in the longitudinal direction, approximately 1/2 of the width of the seal portion, parallel to the end of the cup and the portion of the seal portion, and the leg of the cup. To form the legs of the cup that are separated from the perforation-like perforated cut lines, the shape of which is an isosceles trapezoid or rectangle, and to insert the apex of the center part into the lower part of the sealing part of the cup body. Insert a punch (notch) with a slight width and a length of about 1/2 of the width of the leg part, and cut the leg part from the seal part from the perforated break line , separated from the cup body, and inserted into the insertion openings provided at the lower portions of the sealed portions on both sides of the cup. As a detachable leg, it is a type that the user assembles by himself. The advantage of this type is that it can be completely flat without any projections on the plane when folded, and it can be used to form a cup leg at a lower cost. In addition, when the beverage in the cup is immediately consumed, there is no need to place the cup on a ground surface such as a desk or table, and the cup can be discarded as it is. The point is that it can be used properly.

The detachable leg type described above can also be applied to folding cups having reverse tapered shapes. When forming a folded cup in the shape of a quadrangular prism, elliptical cylinder, or cylinder having an inverse tapered shape according to the present invention, widen the width of the sealed portions at both ends of the cup, and the central portions of the sealed portions on both sides. In addition, it has a length of about 1/3 to 1/2 in the longitudinal direction, which is the vertical direction of the cup, and a width of about 1/2 of the sealing portion, and is parallel to the end of the cup and the sealing portion. , The leg part of the cup that is parallel to the inclination angle of the cup that forms an inverse tapered shape, and that is peeled off from the cut line by the perforation-like breaking line in which the shape of the leg part of the cup forms an isosceles trapezoid or rectangle. At the apex of the center part, a punch (notch) with a slight width and a length of about 1/2 of the width of the leg part for inserting into the lower part of the sealing part of the cup body is made, The legs are separated from the cup main body along perforation-like cut lines from the seal portions, and are inserted into the insertion openings provided at the lower portions of the seal portions on both sides of the cup. As a detachable leg, it is a type that the user assembles by himself. The advantage of this type is that it can be completely flat with no projections on the plane when folded, and that the legs can be formed at a lower cost. In addition, when the beverage in the cup is immediately consumed, there is no need to place the cup on a ground surface such as a desk or table, and the cup can be discarded as it is. The point is that it can be used properly.

In the above-mentioned method, the leg portions are formed by a method in which two independent legs are pressure-bonded to the pressure-bonded seal portions on both sides of the cup body, respectively. Separately from the above, it is possible to form a leg part by separately forming a sheet for a leg unit of a small integrally formed open leg type cup, placing it in the central part of the cup forming sheet and pressing and bonding it. is.

Rectangular or square sheet for forming the folding cup body according to the present invention. The length is about 1/4 to 1/5 in the longitudinal direction, and the width is the same as the width of the cup. A sheet for the leg unit of the leg-opening type cup is formed separately, a straight crease perpendicular to the longitudinal direction is made in the center of the longitudinal direction of the sheet, and the cup body is placed in the center of the sheet. A cutout (punching) is made with a slight width that is the same width as the cylindrical wall and side surfaces of the cup-forming sheet excluding the sealed portions on both sides, and when this part unfolds the cup during drinking, the cup is opened and the cup is opened. The cylindrical wall and the lower part of the side, which are deformed into a shape that surrounds the bottom of the bottom of the cup, bend and open the legs in conjunction to become the legs of the cup, and the legs are always on the ground. The legs are opened so as to be parallel to the bottom of the cup, and the cylindrical wall surrounding the bottom surface of the cup and the lower portion of the side surface become the legs of the cup. Also, the leg portion surrounding the bottom surface of the cup serves as a guide for folding back the bottom surface portion of the cup when the cup is unfolded. This cup leg unit is cut out (punched out) from the central part of a small rectangle, and has a crease at both ends in the longitudinal direction of the rectangle that is the same width as the sealing part, and is parallel to the short side at the center. At the center in the lateral direction, there is a crease corresponding to the folding position of the cup and an elongated punched portion in a cut-out state. Except for the crease formed on the bottom surface of the bottom of the cup, all the creases have the same fold positions as the folding cups of each shape, and are bonded so as to work in conjunction with the cup body and bend. So that the center of the crease pressed into each shape of rhombus and square and the center of the cut (punched) leg exactly overlap, the same width as the pressure-bonded seal points on both sides of the cup, and the cup body Only the lower part of the sealing part is press-bonded by an open-leg type integrally formed leg unit added to the sealing part, and the sealing part of the cup body is preliminarily pressure-bonded before the cup body is pressure-bonded. After pressure-bonding an open-leg type integrally-formed leg unit to be added to the sealing portion of the cup body to the central portion of the cup-forming sheet of the cup body, the cup body folded in two is pressure-bonded to form an integral unit. This completes the quadrangular prism-shaped folding cup according to the present invention to which the leg unit is added.

Rectangular or square sheet for forming the folding cup body according to the present invention. The length is about 1/4 to 1/5 in the longitudinal direction, and the width is the same as the width of the cup. A sheet for the leg unit of the open leg type cup is formed separately, and is placed in the center of the same sheet in the longitudinal direction, with the same width as the cylindrical wall and the side surface, except for the sealing parts on both sides of the sheet for the cup body. , Cut out (punch) with a slight width, and when this part unfolds the cup at the time of drinking, it is opened and the shape of the bottom of the bottom of the cup surrounds the circumference of the cylindrical wall and side The lower part bends and spreads in conjunction to become the legs of the cup. And the lower part of the side becomes the leg of the cup. Also, the leg portion of the cup surrounding the bottom surface of the cup serves as a guide when the bottom portion of the bottom portion of the cup is folded back when the cup is unfolded. This cup leg unit is cut out (punched out) from the central part of the small rectangular shape. There are creases corresponding to the folding positions of , and an elongated, punched-out portion in the cut-out state. Except for the crease formed on the bottom surface of the bottom of the cup, all the creases have the same fold positions as the folding cups of each shape, and are bonded so as to work in conjunction with the cup body and bend. So that the center of the crease pressed into each oval and circular shape and the center of the cut (punched) leg overlap exactly, the cup body is the same width as the pressure-bonded seal points on both sides of the cup. An open-leg type integrally formed leg unit added to the sealing part of , and pressure bonding is performed only to the lower part of the sealing part, and before pressure bonding of the cup body, it is pressure bonded to the sealing part of the cup body in advance. . After press-bonding an open-leg type integrally-formed leg unit to be added to the seal part of the cup body to the cup body, the cup body folded in half is pressure-bonded, and the integrally-formed leg unit is added. This completes the elliptical cylindrical or cylindrical folding cup according to the invention.

Two line-symmetrical isosceles trapezoids with the upper base portion of an isosceles trapezoid forming a reverse tapered shape of a prescribed size as a common axis of symmetry It has a length of about 1/4 to 1/5 in the longitudinal direction of the sheet that forms a shape in which the pieces are arranged facing each other, the width is the same as the width of the cup, and the inclination angle of the cup that forms the reverse tapered shape of the cup body. Similarly, a sheet for the leg unit of a small integrally formed open-leg type cup having a shape like two axisymmetric isosceles trapezoids arranged facing each other is separately formed, and the sheet is arranged in the longitudinal direction. In the center of the sheet, a straight crease perpendicular to the longitudinal direction is made, and in the center of the sheet, the same width as the cylindrical wall and side surfaces excluding the seal points on both sides of the sheet for the cup body and a slight width When cutting (punching) is performed and this part unfolds the cup at the time of drinking, the cylindrical wall and the lower part of the side surface that are opened and deformed into a shape that surrounds the circumference with the shape of the bottom of the cup , The legs are bent and spread in conjunction with each other to form the legs of the cup, and the legs are always spread so that they are parallel to the ground surface. The part becomes the leg of the cup. Also, the leg portion surrounding the bottom surface of the cup serves as a guide for folding back the bottom surface portion of the cup when the cup is unfolded. This is a cup leg unit that cuts out (punches) the central part of the shape in which two small isosceles trapezoids with line symmetry are arranged facing each other. At both ends of the shape in the longitudinal direction, there are creases of the same width as the sealing area, and in the center of these creases, there is a crease that is the same as the inclination in the transverse direction, and in the center of the transverse direction, there is a crease that corresponds to the folding position of the cup. , with an elongated, punched-out portion in the cut-out state. Except for the shape creases formed on the bottom surface of the cup, all of the shapes have creases at the same folding positions as the folding cups of each shape, and are bonded so as to work in conjunction with the cup body and bend. So that the center of the crease pressed into each shape of rhombus and square and the center of the cut (punched) leg exactly overlap, the same width as the pressure-bonded seal points on both sides of the cup, and the cup body Only the lower part of the sealing part is press-bonded by an open-leg type integrally formed leg unit added to the sealing part, and the sealing part of the cup body is preliminarily pressure-bonded before the cup body is pressure-bonded. After press-bonding an open-leg type integrally-formed leg unit to be added to the seal part of the cup body to the cup body, the cup body folded in half is pressure-bonded, and the integrally-formed leg unit is added. This completes the square pole-shaped folding cup having the reverse tapered shape according to the invention.

Two isosceles trapezoids with line symmetry, with the upper base portion of the reverse tapered isosceles trapezoid of the specified size as the common axis of symmetry for the formation of the cup, related to the formation of the folding cup body according to the present invention. It has a length of about 1/4 to 1/5 in the longitudinal direction of the sheets arranged facing each other, the width is the same as the width of the cup, and the inclination angle is the same as the inverse tapered shape of the cup body. A separate sheet for the leg unit of a small, integrally-formed open-leg type cup having a shape in which two isosceles trapezoids having line symmetry are arranged facing each other is formed separately, In the center, excluding the seal points on both sides of the sheet for the cup body, a cutout (punching) is made with a slight width that is the same as the cylinder wall and side surfaces, and when this part unfolds the cup when drinking. , The cylindrical wall and the lower part of the side, which are opened and deformed into a shape that surrounds the bottom of the bottom of the cup, bend and open the legs in conjunction to become the legs of the cup, and the legs of the cup. The legs are always spread parallel to the ground surface, and the cylindrical wall surrounding the bottom surface of the cup and the lower portion of the side surface are the legs of the cup. Also, the leg portion surrounding the bottom surface of the cup serves as a guide for folding back the bottom surface portion of the cup when the cup is unfolded. This is a cup leg unit that cuts out (punches) the central part of the shape in which two small isosceles trapezoids with line symmetry are arranged facing each other. At both ends of the shape in the longitudinal direction, there are creases of the same width as the sealing part, and at the center of the creases are the creases that are the same as the slant in the transverse direction, the crease corresponding to the folding position of the cup, and the cut-out elongated, There is a punched part. Except for the crease formed on the bottom surface of the bottom of the cup, all the creases have the same fold positions as the folding cups of each shape, and are bonded so as to work in conjunction with the cup body and bend. So that the center of the crease pressed into each oval and circular shape and the center of the cut (punched) leg overlap exactly, the cup body is the same width as the pressure-bonded seal points on both sides of the cup. An open-leg type integrally formed leg unit added to the sealing part of , and pressure bonding is performed only to the lower part of the sealing part, and before pressure bonding of the cup body, it is pressure bonded to the sealing part of the cup body in advance. . After press-bonding an open-leg type integrally-formed leg unit to be added to the seal part of the cup body to the cup body, the cup body folded in half is pressure-bonded, and the integrally-formed leg unit is added. This completes the elliptical or cylindrical folding cup having the reverse tapered shape according to the invention.

The square prism-shaped, elliptical cylinder-shaped or cylindrical-shaped folding cup according to the present invention has a simple shape and structure, and therefore requires a complicated manufacturing process because it only needs to be pressed and pressure-bonded at two flat locations. Therefore, mass production becomes possible, and at the same time, it leads to suppression of manufacturing costs. Moreover, the shape of the unfolded cup at the time of drinking is a shape that combines practicality and design.

To assemble the square prism-shaped folding cup according to the present invention from the folded state, the right and left sides of the cup are placed from the seal points on both sides of the cup toward the center of the cup so that the shape of the bottom surface of the bottom of the cup is formed. The cup can be easily assembled by applying an equal force from both directions and finally folding back the folds of the rhombic or square portion of the bottom surface of the cup. The shape of the bottom of the bottom of the cup when viewed from directly below in the vertical direction is a rhombus or a square. A congruent shape having the same shape and size is also formed on the drinking mouth side, which is the opening in the opposite direction, so that the shape of the cup can be stably maintained.

When assembling the elliptical cylindrical or cylindrical folding cup according to the present invention from the folded state, the seal points on both sides of the cup are directed toward the center of the cup so that the shape of the bottom surface of the bottom of each cup is formed. The cup can be easily assembled by applying equal force from both left and right directions and finally folding back the elliptical or circular portion of the bottom surface of the cup. The shape of the bottom surface of the bottom of the cup when viewed from directly below in the vertical direction is elliptical or circular. A congruent shape having the same shape and size is also formed on the drinking mouth side, which is the opening in the opposite direction, so that the shape of the cup can be stably maintained.

When assembling the inverted-tapered quadrangular prism-shaped folding cup according to the present invention from the folded state, the seals on both sides of the cup move from the sealing points on both sides to the center of the cup so that the shape of the bottom of the cup is formed. The cup can be easily assembled by directing it toward the cup, pulling it with equal force from both left and right directions, and finally folding back the rhombic or square portion of the bottom surface of the cup. The shape of the bottom of the bottom of the cup when viewed from directly below in the vertical direction is a rhombus or a square. A similar shape having the same shape is also formed on the drinking mouth side, which is the opening in the opposite direction, so that the shape of the cup can be stably held.

To assemble the elliptical cylindrical or cylindrical folding cup having an inverse tapered shape according to the present invention from the folded state, the drinking mouth of the cup is pulled from the sealing points on both sides of the cup so that the shape of the bottom surface of the bottom of each cup is formed. The cup can be easily assembled by pulling it toward the center of the cup with equal force from both left and right directions and finally folding back the oval or circular part of the bottom surface of the cup. The shape of the bottom surface of the bottom of the cup when viewed from directly below in the vertical direction is elliptical or circular. A similar shape having the same shape is also formed on the drinking mouth side, which is the opening in the opposite direction, so that the shape of the cup can be stably held.

In the square prism-shaped cup according to the present invention, the liquid is concentrated in one place at the two apex portions of the square prism except for the seal portions at both ends, so it is suitable for small children. Also easy to drink. In addition, the elliptical cylindrical or cylindrical cup according to the present invention can be used from any part of the rim, which is on the circumference of the ellipse or on the part of the circumference excluding the parts where the seals are placed at both ends, like a normal cup. can drink

By increasing the length of each side of the rhombus or square shape of the mouthpiece, the capacity of the square prism is increased at the same time, and the size and capacity can be freely changed. In addition, by lengthening the circumference of an ellipse or the circumference of a circle, which is another mouth shape, the capacity of the elliptical cylinder or cylinder can be increased at the same time, and the size and capacity can be freely changed. .

A single folding cup according to the present invention cannot be placed on a ground surface such as a desk or table by itself. Can be used like a cup. In addition, the width of the sealing portion on both sides of the cup is widened, and detachable legs are formed in this portion by perforation-like cut lines, and are separated from the main body when drinking to seal both sides of the cup. It can also be processed to attach detachable legs by inserting it into the socket provided at the bottom of the part. In addition, since the width of the sealing portion is sufficiently secured at that time, there is no fear of liquid leakage, breakage, or the like. There is no need to put the cup on the ground, and if you drink it up immediately and throw it away, there is no need to cut off the legs formed by the perforation-like break lines at the seal points on both sides. , can be selected depending on whether or not they are used.

Although the handle part is not formed, the sealing positions on both sides of the cup, which are the pressure bonding parts that form the cup, have a certain width, so they can also serve as the handle part. In particular, formation of a handle portion is basically unnecessary. In addition, even when a hot drink is put in, if you hold this part, the heat will not easily transfer to your hand, so it has the advantage of being able to be held for a relatively long time.

The folded state can be stored in a smooth and completely horizontal plate shape without irregularities such as rectangles, squares, or trapezoids. It can be stored and carried without taking up space for use or portability.

By using a dedicated stand, the folding cup can be stably placed on the ground surface of the desk, table, etc. while suppressing the manufacturing cost per cup.

When compared with ordinary cups made of paper or plastic resin when the same number of cups are stacked, the thickness when folded (height when stacked) can be compressed to about 1/3 to 1/4. .

At the time of disposal, it becomes thin and compact when it is returned to its original folded state, and there is no need to prepare a trash box dedicated to cups, neatly stack and crush the cups in order.

At the boundaries between the seal portions in the longitudinal direction of both ends of the cup-forming sheet, the positions of creases 5, 5', 6, and 6' that form valley folds with respect to the outer side of the cup are sealed. It becomes the boundary part with the part. T3 and T4 indicate the cylindrical wall and side surface of the collapsible cup. It is in a flat folded state with a rectangular or square shape when folded.

The as-formed condition of the cup as well as the folded condition is shown in FIG. 22B. From this state, it is 5, 6, t'5, t'6, 01b, 02b, w3, w4 that become the part of the bending range of motion for assembling and deploying the cup.

Next, the procedure for assembling and unfolding the bag for drinking from the folded state will be described. Since the development procedure is performed in the same manner as in the first embodiment, the drawings of the first embodiment are also used. FIG. 22B shows a front view of the cup in the formed and folded states of the second embodiment as seen from the horizontal side, which is the same state as shown in FIG. 11A. When folded, it is composed of two surfaces T3 and T4, which are the cylindrical wall of the cup and the side surfaces, excluding the portions where the seals are placed at both ends. First, hold the portions P3 and P4 of the sealing portions on both sides of the cup, and as shown in A of FIG. 16B is obtained by bending toward the center with equal force from both left and right directions so as to form an elliptical or circular crease. When the cup in this state is viewed from directly above in the vertical direction, it becomes as shown in FIG. 19B. At the bottom portion of the bottom of the cup, there are w3 and w4 of folding positions. 01b and 02b are portions that are expanded and bent when the cup is unfolded, and at the same time are portions that are folded back in the opposite direction inside the cup. Next, the unfolded cup body is turned upside down, and auxiliary lines 01b and 02b are used to assist smooth folding in the direction of arrow R, as in the first embodiment shown in FIG. 14A. As shown in FIG. 20B, the elliptical or circular t'5 and t'6 portions that are the base of the bottom of the cup and the folded portions of w3 and w4 are the portions of the cup. From the outside, the part that holds the liquid is formed into an elliptical or cylindrical shape by folding the same shape in the opposite direction to the inside of the cup along the uneven part of the crease so that it has the same elliptical or circular shape as the crease. This completes the folding cup as shown in FIG. 18B. When the bottom surface of the bottom of the cup is folded back inside the cup, the shape of the bottom surface of the bottom of the cup is fixed, and at the same time, the cylindrical wall and side surface on the drinking mouth side, that is, the side portion of the elliptical cylinder or cylinder is also fixed. This is because the area of the bottom of the bottom of the cup is the same as when it was folded, so by folding it back in the opposite direction, lateral pressure is applied to the cylindrical wall and side surfaces, and the shape of the crease of the bottom of the bottom of the cup that you want to form is the shape of the cup. This is because the bottom surface of the bottom is to be fixed. In addition, the state shown in FIG. 18B is a view from the bottom side opposite to the mouth side so that the state of the bottom of the cup during use can be easily understood. When the cup in this state is viewed from directly below in the vertical direction, it becomes as shown in FIG. 20B. FIG. 9A is a front view showing the unfolded state of the cup at the time of drinking from just beside in the horizontal direction. Also, a side view showing the unfolded state at the time of drinking from right beside in the horizontal direction is as shown in FIG. 10A, like the first embodiment.

FIG. 19B shows the upper part of the unfolded cup at the time of drinking as viewed from directly above in the vertical direction. It becomes the upper part t04 and t'04 of the pasting location of P4. For drinking, the spout e formed at the edge t5 of the cup and the spout f formed at the edge t6 of the cup are used, and the glued portion of t03 and t'03 above the sealing portion is used. g, t04, t'04 pasted portion h above the sealing portion is not suitable for drinking. FIG. 20B shows the lower part of the cup in the unfolded state at the time of drinking as viewed from directly below in the vertical direction, and shows the lower parts w03 and P4 of the joints of the seal points P3 on both sides. The lower part becomes w04. As can be seen from B in FIGS. 19 and 20, the elliptical or circular shape of the base of the bottom of the cup placed in the center of the cup-forming sheet is at the same time the same as the shape of the drinking spout. In addition, when the area of the bottom surface of the bottom of the cup is greatly increased, the area of the mouth of the top of the cup is also increased proportionally, so that the capacity of the cup can be freely changed.

An embodiment of the inverted tapered quadrangular prism-shaped folding cup according to the third embodiment of the present invention will now be described in detail.

FIG. 24C is a perspective view showing an example of the folding cup of the third embodiment in an unfolded state at the time of drinking. 24C is a perspective view of the upper portion of the cup as viewed from the direction of the spout during drinking. Of the four apexes of the upper part of the square prism forming an inverse tapered shape in the direction of arrow X, which is the vertical direction of the upper part (drinking mouth) of the cup, two of the apexes are located at the seal points on both sides of the cup. The remaining two vertex portions are used as the spouts i and j, except for the vertex portions k and l that are not suitable for drinking.

As shown in FIG. 24C, the folding cup of the third embodiment has a shape that spreads from the bottom side to the mouth side like a general cup, and is wider than that of the first embodiment. Wide mouth side.

A method and procedure for forming the folding cup of the third embodiment will be described. FIG. 25C shows an exploded view of the cup-forming sheet before formation. A straight line connecting w05, w5 and w6, w06 in the center is a place to fold in half.

The drinking mouth of a normal general cup is circular, and the whole is in the shape of a gentle inverted truncated cone or cylinder, but as shown in FIG. The shape of the main part of the cup is a square prism with an inverse tapered shape, which is different from the shape of a general cup.

There is no difference from the first embodiment when the cup is viewed from vertically above and vertically below when drinking in the third embodiment, so it is omitted. The area becomes wider as it approaches the mouth side.

P5 and P6 shown in the developed view of C of FIG. 25 and P1 and P2 shown in the developed view of A of FIG. 6 are sealing portions of the cup. The major difference is that the shape of the sealing portion in the first embodiment is a rectangle, whereas the shape of the sealing portion in the third embodiment is a parallelogram. The numbers of angles 101 and 102 shown in KC of FIG. 44 do not represent the angles themselves, but are for comparing the positions of the inclination of the cup. The steeper the angle of the inclined position, the greater the elasticity of the auxiliary lines 7b and 8b shown in FIG. Since there is no gap, the deployment becomes uneven, so it is preferable to set the angle as gentle as possible. In addition, as shown in C of FIGS. 26 and 27, a short and narrow space u between the sealed portions on both sides of the cup also causes unsmooth deployment. Furthermore, the wider the width of the seal points P5 and P6 is, the closer the angles 101 and 102 are to a right angle.

t05 and t'05, t7 and t9, t8 and t10, t06 and t' centering on the positions of w05, w5, w6, and w06 in the center dividing the cup forming sheet into two in the longitudinal direction shown in FIG. 25C. 06, opposite sides of the sheet in the short direction are folded in half in the folding direction Q of the sheet to form P5 and P'5, P6 and P'6 on both sides of the cup. Pressure bonding is performed at the sealing portion of

A horizontal end-on view of the cup as it is formed and folded is shown in FIG. 26C. An elliptical cylindrical or cylindrical folding cup having an inverse tapered shape according to a fourth embodiment, which will be described later, also has the same pressure-bonded shape. P5 and P6 shown in C of FIGS. 26 and 27 are portions of pressure-bonded sealing portions of the cup. This basic structure and shape are applied to all shapes of folding cups according to the present invention, from the first embodiment to the sixteenth embodiment.

In order to implement the folding cup of the third embodiment, two isosceles trapezoids that are linearly symmetrical with the upper base of the isosceles trapezoid as a reference and the upper base of the isosceles trapezoid as a common axis of symmetry are formed. From the cup forming sheet having a shape in which the cups are arranged facing each other, the cup is easily folded in each direction so that it can be easily folded into a mountain fold or a valley fold to be in an unfolded state at the time of drinking. The specified concave and convex folds related to the formation are pressed and put into the same sheet in advance. This should be done prior to the pressure bonding involved in forming the cup body. As shown in FIG. 25C, t'7, t'8, t'9, t'10 forming a rhombus or square, and main folds of the tube wall and the side surface T5 with the spout i during the formation of the cup. 7, an auxiliary line 7b incidental to the fold 7 that assists in smoothly folding the bottom surface of the bottom of the cup, a main fold 8 of the cylindrical wall and the side surface T6 having the spout j when forming the cup. And press molding is simultaneously performed with the mold of the auxiliary line 8b attached to the fold line 8, which similarly assists in smoothly folding back the bottom surface of the bottom of the cup. The crease 9 and the crease 9 ′ forming the boundary with P5 of the sealing part are valley folds to the outside of the cup, the creases 7 and 8 are mountain folds to the outside of the cup, t′7, t of the rhombus or square part Folds '8, t'9, t'10 are mountain folds to the outside of the cup, auxiliary lines 7b and 8b are valley folds to the outside of the cup, fold 10 forming the boundary with P6 of the sealing location , the crease 10′ is a valley fold with respect to the outside of the cup, and the folds w5 and w6 and w05 and w06 at the bottom of the sealing portion are all mountain folds with respect to the outside of the cup, and the mountain folds are convex and valley folds. is concave and presses each crease. This fold press is the cornerstone of the folding cup according to the present invention, and serves as a guide when assembling and forming the cup. It's the important part.

As shown in FIG. 25C, two isosceles trapezoids that are linearly symmetrical with the upper base of the isosceles trapezoid as a reference and the upper base of the isosceles trapezoid as a common axis of symmetry are placed face to face. From the cup forming sheets arranged in a shape, the center of the 1/2 of the sheet in the longitudinal direction and the positions w05, w5, w6, and w06 where the sheet is folded and bent are set as the reference line, and the line is set as the axis of symmetry. A line-symmetrical isosceles triangle or right-angled isosceles triangle, that is, the overall shape of which is a rhombus or a square, is pressed into the central portion of the sheet and arranged to form the bottom surface of the cup. When this portion is folded, t'7 and t'9 and t'8 and t'10 overlap. Furthermore, in the longitudinal direction from the center of the short direction of the same sheet, a fold line 7 and a fold line 8 that form a mountain fold are added to the outer side of the cup, and these folds are used as the unfolded position to form an inverted tapered square prism shape. At the folding position for forming the cup, the fold with the spout is formed. The standard shape of the base of the bottom of the cup is a rhombus, and as the area of the bottom of the cup and the area of the drinking mouth are increased, the rhombus gradually approaches a square, and the upper limit of the shape that can be formed is a square. Become.

As shown in FIG. 25C, the cup-forming sheet is folded in two at folding points w05, w5, w6, and w06 so that t05 and t'05, t7 and t9, t8 and t10, and t06 and t'06 are folded. At the overlapping positions, pressure bonding is performed using the entire longitudinal portions forming parallelograms of P5 and P'5 and P6 and P'6 as sealing points, respectively.

This results in the as-formed and folded condition of the pressure-bonded cup as shown in FIG. 26C. Sealing points are P5 and P6. Folds 9, 9', 10, and 10', which are valley folds toward the outer side of the cup, are formed along the boundaries between the portions of the cup-forming sheet and the sealing portions in the longitudinal direction of both ends of the cup-forming sheet as the sealing portions. becomes the boundary of T5 and T6 indicate the cylindrical wall and side surface of the collapsible cup. When folded, it forms an isosceles trapezoid shape and is in a flat folded state.

The state immediately after the formation of the cup is shown in FIG. 26C. 7, 8, 9, 10, t'7, t'8, t'9, t'10, 7b, 8b, 7b, 8b, They are w5 and w6.

Next, the procedure for assembling and unfolding the bag for drinking from the folded state will be described. Since the development procedure is performed in the same manner as in the first embodiment, the drawings of the first embodiment are also used. FIG. 26C shows a front view of the cup in the formed and folded states of the third embodiment as seen from the horizontal side, which is the same state as shown in FIG. 11A. When folded, it is composed of two surfaces T5 and T6, which are the cylindrical wall of the cup and the side surfaces, excluding the portions where the seals are placed at both ends. First, hold the portions P5 and P6 of the sealing portions on both sides of the cup, and as shown in A of FIG. When it is folded toward the center with an equal force from both the left and right sides so as to form a rhombic or square crease, the state shown in FIG. 13A is completed. At the bottom portion of the bottom of the cup, there are w5 and w6 of folding positions. Reference numerals 7b and 8b denote portions that are expanded and bent when the cup is unfolded, and at the same time, are portions that are folded back inside the cup in the opposite direction. Next, as shown in FIG. 14A, the unfolded cup body is turned upside down. Mainly the auxiliary lines 7b and 8b that assist in folding in the direction of arrow R shown in A of FIG. t'7, t'8, t'9, t'10 and w5, w6 folds from the outside of the cup so that they are the same rhombus or square as the creases. By folding the inside of the cup in the opposite direction along the same shape, the part for storing the liquid is formed into a square prism shape with an inverse tapered shape, and the folding cup as shown in FIG. 24C is completed. . When the bottom surface of the bottom of the cup is folded back inward, the shape of the bottom surface of the bottom of the cup is fixed, and at the same time, the cylindrical wall and side surface on the side of the drinking mouth, that is, the side surface of the square prism forming an inverse tapered shape, is also fixed. be done. This is because the area of the bottom of the bottom of the cup is the same as when it was folded, so by folding it back in the opposite direction, lateral pressure is applied to the cylindrical wall and side surfaces, and the shape of the crease of the bottom of the bottom of the cup that you want to form is the shape of the cup. This is because the bottom surface of the bottom is to be fixed. FIG. 27C is a front view showing the unfolded state of the cup at the time of drinking from the side in the horizontal direction. FIG. 31C is a side view showing the unfolded state of the cup at the time of drinking from the side in the horizontal direction.

As shown in FIG. 24C, the upper part of the unfolded cup at the time of drinking is the upper parts t05 and t'05 where the sealing points P5 on both sides are joined, and the upper parts t06 and t'06 where the P6 are joined. consists of For drinking, the spout i formed at the fold 7 and the spout j formed at the fold 8 are used. The lamination portion 1 of t06, t'06 above the portion of is not suitable for drinking. The lower part of the cup is the lower part w05 where the seal points P5 on both sides are joined, and the lower part w06 where the seal points P6 are joined. As can be seen from C in FIGS. 24 and 25, the shape of the rhombus or square that forms the base of the bottom of the cup placed in the center of the cup-forming sheet is at the same time the same as the shape of the drinking spout. Its size and area are smaller toward the bottom of the cup and larger toward the mouth of the cup. In addition, when the area of the bottom surface of the bottom of the cup is greatly increased, the area of the mouth of the top of the cup is also increased proportionally, so that the capacity of the cup can be freely changed.

Now, an embodiment will be described in detail with respect to an elliptical cylindrical or cylindrical folding cup having an inverse tapered shape according to the fourth embodiment of the present invention.

An example of the folding cup of the fourth embodiment in an unfolded state for drinking is shown in D of FIG. It is assumed that the shape of the main portion that accommodates the liquid is an elliptical cylinder or cylinder that forms an inversely tapered shape. 2 places on the elliptical circumference or part of the circumference of the upper part of the cup, excluding the 2 places o and p that are not suitable for drinking, which are located at the sealing places on both sides of the cup, and the remaining 2 places The circumference of the ellipse or the edge of the portion of the circumference is used as the mouthpiece m and the mouthpiece n.

As shown in D of FIG. 30, the folding cup of the fourth embodiment has a shape that widens from the bottom side toward the mouth of the cup like a general cup, and the mouth of the folding cup of the fourth embodiment is wider than that of the second embodiment. the sides are wider.

A method and procedure for forming the folding cup of the fourth embodiment will be described. A developed view of the cup-forming sheet before formation is shown in D of FIG. 28 . The position of the straight line connecting w07, w7 and w8, w08 in the center is the part where the paper is folded in two.

The drinking mouth of a normal general cup is circular and has a shape of a truncated cone or cylinder with a gentle reverse taper shape as a whole, but as shown in D of FIG. In the cup, the shape of the main portion of the main body is an elliptical cylinder or a cylinder having a reverse tapered shape, which is close to the shape of a general cup.

There is no difference from the second embodiment when the cup is viewed from vertically above and vertically below when drinking in the fourth embodiment, so it is omitted here. The area becomes wider as it approaches the mouth side.

P7 and P8 shown in the developed view of D in FIG. 28 are sealing portions of the cup. The major difference is that the shape of the sealing portion in the second embodiment is a rectangle, whereas the shape of the sealing portion in the fourth embodiment is a parallelogram. The numbers of angles 101 and 102 shown in KD of FIG. 47 do not represent the angles themselves, but are used to compare the inclined positions of the cup. As the angle of the inclined position becomes steeper, when the bottom surface of the cup is folded back, the portion of the auxiliary lines 03b and 04b shown in FIG. It is preferable that the angle is as gentle as possible because the stretchability is lost and the deployment becomes uneven. In addition, as shown in D of FIGS. 29 and 30, a short and narrow space u between the sealed portions on both sides of the cup also causes unsmooth deployment. Furthermore, the wider the width of the sealing portions of P7 and P8, the closer the angles 101 and 102 are to a right angle.

t07 and t'07, t11 and t12, and t08 and t'08 are accurately centered around the central positions of w07, w7, w8, and w08 dividing the cup-forming sheet in the longitudinal direction shown in D of FIG. The opposite sides of the sheet in the short direction are folded in half in the folding direction Q of the sheet so that the opposite sides of the sheet overlap, and the seal points of P7 and P'7 and P8 and P'8 on both sides of the cup are sealed. Partial pressure bonding.

FIG. 29D shows an end-on horizontal front view of the cup as it is formed and folded. P7 and P8 shown in D of FIGS. 29 and 30 are portions of pressure-bonded sealing portions of the cup. This basic structure and shape are applied to all shapes of folding cups according to the present invention, from the first embodiment to the sixteenth embodiment.

In order to implement the folding cup according to the present invention of the fourth embodiment, the upper base portion of the isosceles trapezoid is used as a common axis of symmetry with the upper base portion of the isosceles trapezoid as a reference, line symmetry, etc. A cup-forming sheet having a shape in which two trapezoidal legs are arranged facing each other is easily folded in each direction so as to be easily folded into a mountain fold or a valley fold to be in an unfolded state at the time of drinking. In addition, the specified concave and convex creases related to the formation of the cup serving as a guide are pressed and put into the same sheet in advance. This should be done prior to the pressure bonding involved in forming the cup body. As shown in FIG. 28D, t'11 and t'12 forming an ellipse or circle, a cylinder wall and a side surface T7 having a mouthpiece m when forming the cup, and a bottom surface of the bottom of the cup are folded back. Auxiliary line 03b, which is also the minor axis radius in an elliptical shape and the radius in a circular shape, as well as the cylindrical wall and side surface T8 with the mouthpiece n in the formation of the cup, as well as In the case of an ellipse, the auxiliary line 04b, which is also the minor axis radius and the radius of the circular shape, is used to assist the smooth folding of the bottom surface of the bottom of the cup. conduct. The crease 11 and the crease 11 ′ forming the boundary with the seal point P7 are valley folds toward the outside of the cup, the crease 12 and the crease 12 ′ forming the boundary with the seal point P8 are valley folds toward the outside of the cup, The creases t'11 and t'12 of the elliptical or circular portion are mountain folds against the outside of the cup, the minor axis radius in the ellipse, and the radius in the circle, auxiliary line 03b, auxiliary line 04b is the valley fold to the outside of the cup, the major axis radius in the elliptical shape and also the radius in the circular shape. On the other hand, all the folds are mountain folds, and the mountain folds are convex and the valley folds are concave, and the respective creases are pressed. This fold press is the cornerstone of the folding cup according to the present invention, and serves as a guide when assembling and forming the cup. It's the important part. The fourth embodiment is the same as the one shown in FIGS. 19 and 20B of the second embodiment, so the drawing is omitted, but the drinking spout at the top of the cup and the rim of the cup are the same as those of a general cup. Since the cylindrical wall and the side surfaces T7 and T8 of the cup are not provided with creases that bend for unfolding, the cylindrical wall and the side surface T7 are provided with an auxiliary line for forming a drinking mouth that serves as a curved guide. r3, the cylinder wall, and the side surface T8 are provided with only a drinking spout forming auxiliary line r4 that serves as a curved guide.

As shown in D of FIG. 28, two isosceles trapezoids that are linearly symmetrical with the upper base of the isosceles trapezoid as a reference and the upper base of the isosceles trapezoid as a common axis of symmetry are placed face to face. From the cup-forming sheets arranged in a shape, the center of the 1/2 of the sheet in the longitudinal direction, and the positions w07, w7, w8, and w08 where the sheet is folded and bent are set as the reference line, and the line is set as the axis of symmetry. A line-symmetrical semi-ellipse or semi-circle, that is, the overall shape of the sheet is an ellipse or a circle. When this portion is folded, t'11 and t'12 overlap. Furthermore, as shown in FIG. 28D, a formation auxiliary line r3 is provided in the longitudinal direction from the center of the sheet in the lateral direction to facilitate the formation of an elliptical or circular shape at the mouth portion when drinking. , r4 at a folding position for forming an elliptic cylindrical or cylindrical folding cup by adding a crease that becomes a mountain fold to the outer side of the cup with a slight length, and making it an unfolded position, It becomes a crease with a spout. The standard shape of the bottom surface of the bottom of the cup is elliptical, and as the area of the bottom surface of the bottom of the cup and the area of the drinking mouth are increased, the elliptical shape gradually approaches a circular shape. The upper limit is circular.

As shown in D of FIG. 28 , the cup-forming sheet is folded in two at the fold points w07, w7, w8, and w08, and at positions where t07 and t'07, t11 and t12, and t08 and t'08 overlap, respectively. , P7 and P'7, and P8 and P'8, which form parallelograms, are pressure-bonded as seal points.

This results in the as-formed and folded condition of the pressure-bonded cup as shown in FIG. 29D. Sealing points are P7 and P8. Folds 11, 11', 12, and 12', which form valley folds with respect to the outside of the cup, are formed at the boundaries between the portions of the cup-forming sheet in the longitudinal direction at both ends thereof where the cup is to be sealed. , a boundary portion with the sealing portion. T5 and T6 indicate the cylindrical wall and side surface of the collapsible cup. When folded, it forms an isosceles trapezoidal shape and is in a flat folded state.

The state immediately after the formation of the cup is shown in FIG. 29D. 11, 12, t'11, t'12, 03b, 04b, w7, and w8 are the parts of the bending range of motion for assembling and deploying the cup from this state.

Next, the procedure for assembling and unfolding the bag for drinking from the folded state will be described. Since the development procedure is performed in the same manner as in the first embodiment, the drawings of the first embodiment are also used. FIG. 29D shows a front view of the cup in the formed and folded states of the fourth embodiment as seen from the horizontal side, which is the same state as shown in FIG. 11A. When folded, it consists of two surfaces T7 and T8, which are the cylindrical wall of the cup and the side surfaces, excluding the portions where the seals are placed at both ends. First, hold the portions P7 and P8 of the sealing portions on both sides of the cup, and as shown in A of FIG. When it is folded toward the center with an equal force from both the left and right sides so as to form a rhombic or square crease, the state shown in FIG. 13A is completed. At the bottom portion of the bottom of the cup, there are w7 and w8 of double-folding positions of folding portions. Auxiliary lines 03b and 04b are portions that are expanded and bent when the cup is unfolded, and at the same time are portions that are folded back inside the cup in the opposite direction. Next, as shown in FIG. 14A, the unfolded cup body is turned upside down. As shown in D of FIG. 28, mainly the auxiliary lines 03b and 04b that assist the smooth folding in the direction of the arrow R shown in A of FIG. The elliptical or circular t'11, t'12 parts and the folding part of w7, w8 are pulled from the outside of the cup along the uneven parts of the folds so that they have the same elliptical or circular shape as the folds. Then, by folding the same shape in the opposite direction inside the cup, the portion for containing the liquid is formed into an elliptical or cylindrical shape with a reverse tapered shape, and the folded cup as shown in D of FIG. 30 is completed. . When the bottom surface of the cup is folded back inside the cup, the shape of the bottom surface of the cup is fixed, and at the same time, the cylindrical wall and side surface on the side of the drinking mouth, that is, the side portion of the elliptical cylinder or cylinder forming a reverse tapered shape. is also fixed. This is because the area of the bottom of the bottom of the cup is the same as when it was folded, so by folding it back in the opposite direction, lateral pressure is applied to the cylindrical wall and side surfaces, and the shape of the crease of the bottom of the bottom of the cup that you want to form is the shape of the cup. This is because the bottom surface of the bottom is to be fixed. FIG. 30D shows a front view of the cup in a state of being unfolded at the time of drinking from right beside in the horizontal direction. Also, a side view showing the unfolded state at the time of drinking from the horizontal direction of the cup has almost the same shape as that of the third embodiment, as shown in FIG. 31C.

The upper part of the unfolded cup at the time of drinking is composed of upper parts t07 and t'07 where the seal points P7 on both sides are joined, and upper parts t08 and t'08 where P8 is joined. For drinking, the mouthpiece m formed at the edge t11 of the cup and the mouthpiece n formed at the edge t12 of the cup are used, and the glued portion of t07 and t'07 above the sealing portion is used. o, the laminating portion p of t08, t'08 above the portion of the sealing portion is not suitable for drinking. The lower part of the cup is the lower part w07 where the seal points P7 on both sides are joined, and the lower part w08 where the seal points P8 are joined. As can be seen from D in FIG. 28, the elliptical or circular shape of the base of the bottom of the cup placed in the center of the cup-forming sheet is at the same time the same as the shape of the spout, but in the second embodiment. Its size and area are smaller toward the bottom of the cup and larger toward the mouth of the cup. In addition, when the area of the bottom surface of the bottom of the cup is greatly increased, the area of the mouth of the top of the cup is also increased proportionally, so that the capacity of the cup can be freely changed.

Side views of the collapsible cups of the first embodiment and the second embodiment as seen from the horizontal side are both shaped as shown in FIG. 10A. When the cup is formed after the pressure bonding is completed, it is in the form of a bag as shown in A of FIG. 7. As shown in A of FIG. Of these, only two points, w01 and w02, are supported on a straight line, and since the bottom structure is unstable, the cup alone can stand on its own by releasing the hand from the ground surface such as a desk or table. is difficult.

Therefore, in order to make it possible to stably place the folding cup according to the first and second embodiments of the present invention on the ground surface, separately formed dedicated cups as shown in L1 and L2 in FIG. The folding cups of the fifth and sixth embodiments are the folding cups of the fifth and sixth embodiments.

The leg of the cup used in the fifth and sixth embodiments is pressure-bonded to the lower part of the sealing portion of the bottom of the cup. is. 33 and 34 are viewed from the bottom side of the bottom of the cup in the direction of the arrow Y. FIG. Similarly, LA and LB in FIG. 35 show the state from folding to just before use when viewed from the arrow Y direction on the bottom side of the bottom of the cup.

In the fifth embodiment, as shown in A of FIG. 5, legs of a dedicated cup as shown in L1 and L2 of FIG.
