Description

A folding cup with a low height and a filter cup using the same after folding the horizontally; longer than vertically and pressing the edge to spread the bottom so that it is angled}

The present invention relates to a foldable multipurpose cup whose width is longer than length when folded on a flat surface and which is longer than width when unfolded by pressing a fold line portion, and a drip filter cup using the same.

Paper cups are widely used in vending machines, offices, homes, and outdoors, and have features such as mass production, easy handling, and recycling of resources.

However, since the disposable paper cup as described above has a normal cup shape with a wide upper part and a narrow lower part, the bulky burden of the original shape is maintained even when continuously stacked and inserted.

In order to solve this problem, a technology that can be used by unfolding and standing up a foldable paper cup is known as Korean Patent Registration No. 10-1114236. This is a perspective view of the folded state of the foldable paper cup as shown in FIG. 1, a perspective view of the expanded state of the foldable paper cup of FIG. 1 as shown in FIG. 2, a bottom perspective view of the expanded state of the foldable paper cup of FIG. 1 as shown in FIG. A separated perspective view of the paper cup, a developed view of the foldable paper cup according to FIG. 1 as shown in FIG. 5, and a perspective view of the folded state of the paper cup of FIG. 3 as shown in FIG. 6.

As shown in the figure, the cup body 10 made of paper coated with a synthetic resin layer such as polyethylene on one side and the bottom 20 covering the bottom of the cup body 10, the cup body ( 10) is coated on the inner surface and the outer surface of the bottom paper 20 is coated. In addition, when the cup body 10 is unfolded by pressing both ends in a folded state, the unfolded state must be maintained, so a thicker one is used than the bottom paper 20, and the bottom paper 20 is folded and unfolded To make this easier, use something relatively thin and soft.

The cup body 10 forms folding lines 11 and 11' folded at both ends based on the center line in the state in which paper in the form of a rectangle is cut and formed. At this time, the folding lines 11 and 11' may be formed through a pressing operation, or may be formed in the form of a dotted sheath or a pressed line. On both sides of the folding line 11, 11', as the bending lines 12, 12' having a curvature of the curve are symmetrically formed in an elliptical shape, these folding lines 11, 11' and the bending line 12 Press-fitting portions 13 and 13' formed by (12') are made on both sides of the folded cup body. The bending points 14 and 14' formed at the folds of the ends of the bending lines 12 and 12' at the upper and lower ends of the cup body 10 are the upper and lower ends of the cup body 10 extended in an elliptical shape. Since the lower end plays a role of suppressing and weakening the force to return to the folded state, the expanded cup body 10 is maintained as it is.

A bending line 15 in the transverse direction is further formed with respect to the vertical folding lines 11 and 11 'for the press-fitting parts 13 and 13', and when in use, the bending line 15 forms a curved surface. As bending occurs in the middle of the press-fitting parts 13 and 13', it serves to suppress the return force to the folded state. In addition, the bottom paper 20 fused to the inner lower end of the cup body 10 is cut into a rectangular square shape, and then perpendicular to the central fold line 21 rising to cross the central part in the horizontal direction and both sides As shown in FIG. It is folded, and in a state of being inserted into the inner lower end of the cup body 10, the cup body 10 and the cup body 10 are heat-sealed and attached and fixed.

At this time, the inner surface of the cup body 10 is coated with a coating layer, and the outer surface of the bottom paper 20 is coated with a bottom paper coating layer, so that they overlap each other and use heat, high frequency, or ultrasonic waves. When the cup body 10 and the bottom paper 20 are fused to each other in a watertight state, since the bottom coating layer (for example, polyethylene) is melted and adhered to each other when the cup body 10 and the bottom paper 20 are brought into close contact with each other.

In addition, a double fusion method in which the folded ends of the bottom paper are first folded and fused back to the cup body has been developed as domestic patent registrations No. 10-1401814 and No. 10-2186567, but it is used as a large-capacity cup whose height is higher than the folded bottom.

As shown in FIGS. 7 to 13, the foldable cup of the present invention folds the tubular cup body from both sides to form an inner space in which the width in the folded state is longer than the length and the width is shorter than the vertical when unfolded. Folding lines (11, 11 ' ), on both sides of each fold line (11, 11'), the length of the long axis is longer than that of the semi-ellipse and the length of the long axis is shorter than that of the ellipse, and both upper and lower ends of the long axis are cut to form a horizontal plane, and the upper and lower open-type similar elliptical bending lines (12c, 12'c), pressing the fold lines 11 and 11', the press-fitting parts 13 and 13' that open in a flat shape up to the fold lines 12a and 12'a, and between the two fold lines 11 and 11' a cup body 10 having an expansion portion 16, which is a front and rear portion excluding the press-fitting portions 13 and 13', and having a cup body coating layer 10b formed on an inner wall;

A bottom with a bottom coating layer (20b) formed on the surface to be fused with the cup body coating layer (10b) inside the bottom of the cup body (10), and both ends in the lengthwise direction are folded into a band shape, and then the center fold line (21) in the upwardly convex transverse direction The folded part is firstly fused to form a band-shaped band, and the bottom rim of the folded cup body 10 is fused to form a bottom fusion band 20d, and the width of the bottom fusion band 20d is longer Bottom paper (20) with a longer distance from the top to the center fold line (21);

The bottom paper 20 and the cup body 10 are additionally inclined upward from the point where the upper end of the bottom fusion band 20d and the pseudo-elliptical bending lines 12c and 12'c meet to the center of the folding lines 11 and 11'. ) is fused to the inclined fusion line 20f; constituted, including

An auxiliary bending line 20g is further added to the cup body 10 vertically toward the bottom of the cup body 10 at the point where the top of the bottom fusion band 20d and the pseudo-elliptical bending lines 12c and 12c' meet,

The expansion part bottom (D1) of the expansion part 16 between the auxiliary bending lines (20g) and the lower end short axis (R2) of the lower end of the expanded press-fitting parts (13, 13 ') have the same dimensions within the error range, and the expansion part The bottom (D1) and the bottom short axis (R2) are mutually buffered with the auxiliary bottom (D3) bent to be connected to each other, and are configured to maintain the unfolded state.

In the present invention, the lower short axis R2 of the similar elliptical bending lines 12c and 12'c constituting the press-fitting parts 13 and 13' is larger than the upper short axis R1, which is similar up and down in height Also, the minor axis is increased so that the lower area of the bending line 15 is larger, so that the additional fusion is performed with the inclined welding line 20f, so that when the press-fitting part is expanded, the pressing force acts on the lower side to increase, so that the press-fitting part of the cup body 10 When unfolding (13, 13'), it acts to easily maintain the shape of the triangular folded portion 26 on the bottom paper 20, and at the same time, the bottom paper 20 is not spread flat based on the top of the bottom fusion band 20d. To this end, in the triangular fold portion 26, when unfolded, it is double-bent downward and then unfolds horizontally at the same time, so that the pulling force (folding force again) from the bottom is close to zero.

To this end, the bottom paper 20 has a bottom fusion band 20d that is the vertical height of the inclined fusion line 20f greater than the width h1 of the bottom fusion band 20d where the cup body 10 and the bottom paper 20 are fused. When the distance (h2) from the top to the center fold line 21 is configured to be longer, and the press-fitting parts 13 and 13' are unfolded by pressing the fold line 11, the bottom paper 20 press-fitting part 13 , 13') a triangular folded portion 26 in which the lower bottom fusion band 20d and the inclined fusion line 20f are folded to form the same plane;

It is folded in a triangular shape at the triangular fold portion 26, and the center fold line 21 at the bottom of the spread portion D1 descends when unfolded to form a horizontal portion connected horizontally with the upper end of the bottom fusion band 20d.

The bending line 15 and the auxiliary bending lines 15-1 and 15-2 of the present invention are semi-elliptical press-fitting portions 13 that are unfolded when the cup body 10 is unfolded by pressing the folding lines 11 and 11'. , 13 '), the bending line 15 and the auxiliary bending lines 15-1 and 15-2 are pressed in at least one place so that the press-fitting parts 13 and 13' are spread horizontally It is bent so as to enter the inside of the cup body 10 more, and this provides a source force that blocks the central portions of the press-fitting portions 13 and 13' from returning to the folded state. The reason why the bending line 15 and the auxiliary bending lines 15-1 and 15-2 are formed in plural is to implement the bending function even if the vertical positions of the folding lines 11 and 11' pressed according to the user's flight are different. to be.

In the present invention, the cup body coating layer (10b) and the bottom coating layer (20b) of the bottom base paper (20a) are preferably coated with water-soluble and water-soluble emulsions, which are environmentally friendly non-toxic special coatings, which are harmless to the human body and are incinerated or incinerated. It is not harmful to the environment because it does not emit environmental hormones when landfilled, and it can be recycled after use, and it is easy to fold and discard. The main body 10 and the bottom paper 20' in the present invention can be used as a kind of paper, plastic, metal foil, wood, or pulp.

In the present invention configured as described above, the flooring 20 shown below in FIG. 11 is folded at both ends in a first band shape, and then the flooring coating layer 20b is formed around the center fold line 21 on the surface. , and the bottom coating layers 20b of both ends 25 and 25' folded in a strip are fused to each other.

Subsequently, as shown in FIG. 11, the press-fitting parts 13 and 13' formed in a pseudo-elliptical shape with upper and lower openings by the folding lines 11 and 11' and the pseudo-elliptical bending lines 12a and 12'a, and the press-fitting part 13 , 13 ') in the form of a press groove so that the bending line 15, auxiliary bending lines 15-1, 15-2, and auxiliary bending lines 20g perpendicular to the bottom of the auxiliary fusion band 20d are arranged. Pressing is performed, the central portion is folded so that the rim portion overlaps, and both ends are fused into a tubular shape to form an expanded portion fusion line 18 to form a cup body 10 in the form of a folded paper cup as shown in FIG. 12.

Next, in a state where the bottom paper 20 of FIG. 11 is placed on the bottom of the cup body 10 of FIG. 12 with the center fold line 21 facing upward, one of thermal fusion, ultrasonic fusion, and high-frequency fusion is selected. After fusion, the edge of the bottom paper 20 is placed in close contact with the fold lines 11 and 11' of the cup body 10, and then the bottom rim is fused with the bottom fusion band 20d, and the inclined fusion line 20f In this way, it is fused in the form of an oblique line from the top of the pseudo-elliptical bending lines 12c and 12'c and the bottom fusion band 20d to the bending line 15 of the folding lines 11 and 11'.

When using the present invention manufactured as described above, when at least one of the bending line 15 and the auxiliary bending lines 15-1 and 15-2 are pressed in a folded state as shown in FIG. 12, the unfolding portion as shown in FIGS. 8 to 10 (13,13') expands to maintain its shape.

In addition, in this case, an auxiliary bending line 20g is added vertically toward the bottom of the cup body 10 at the point where the top of the bottom fusion band 20d and the pseudo-elliptical bending lines 12c and 12c' meet in the cup body 10. add,

The expansion part bottom (D1) of the expansion part 16 between the auxiliary bending lines (20g) and the lower end short axis (R2) of the lower end of the expanded press-fitting parts (13, 13 ') have the same dimensions within the error range, and the expansion part The bottom (D1) and the lower short axis (R2) are mutually buffered with the auxiliary bottom (D3) bent to be connected to each other and configured to maintain the unfolded state;

The base paper 20 is at the top of the bottom fusion band 20d, which is the vertical height of the inclined fusion line 20f, than the width h1 of the bottom fusion band 20d where the cup body 10 and the bottom paper 20 are fused. When the distance (h2) to the center fold line 21 is configured to be longer, and the press-fitting parts 13 and 13' are unfolded by pressing the fold line 11, the bottom paper 20 press-fitting parts 13 and 13 ') A triangular folded portion 26 in which the lower bottom fusion band 20d and the inclined fusion line 20f are folded to form the same plane;

It has good shape stability and low height, so it is convenient to use it for drinking a small amount of medicine or water, or collecting saliva for confirming COVID-19 infection.

In this case, the height of the fold line (11, 11') side is lower than the bottom length of the cup body (10), and at the same time, the combined height of the bottom paper is fused to reach almost half of the height of the cup body, and once unfolded, it is restored. It is difficult to maintain the unfolded state, and the bottom is almost square, so there is no risk of overturning, and it is suitable for use in reducing the capacity. Suitable for applications with lower heights.

That is, the present invention folded together with the meter reading kit has a structure in which the height of the cup body is lower than the folded bottom, so it is suitable for the use of a small foldable cup. When the user's saliva is collected, a meter reading is performed immediately, and secondary infection can be prevented at the source by folding and discarding it again. This means, for example, when packaging hundreds of thousands or millions of meter reading sets, if the set is made in the form of a folding flat plate and made in the form of a disposable kit, the overall space is reduced, and since it takes up such a small space, it is possible to sell or store a large amount in a small rack, and when used Since it is unfolded and used as a cup, it is easy to use and the storage space is small, so logistics costs for movement are reduced.

In addition, since it is spread out and used for small cups, it is easy to use as a hygienic single-use for western medicine or herbal medicine where a small amount of quantitative intake is important, and it can be used conveniently for children or elderly people with dementia who have a weak concept of quantity.

In this case, the height of the fold line (11, 11') is lower than the bottom length of the cup body (10), and at the same time, the combined height of the bottom filter paper is fused to reach almost half of the height of the cup body, once unfolded It maintains an expanded state so that restoration is difficult, and as shown in FIG. It has almost the same dimensions as (D1) and forms a configuration connected to the auxiliary floor (D3) that is bent obliquely and connects them to maintain their shape and absorb shock. When included, it acts as a driving force to maintain its shape and prevent deformation with an octagonal stable floor. Of course, it will be appreciated that FIG. 10 is a drawing of a foldable cup, but the cup body and the bottom can be replaced with a bottom filter paper having the same configuration, so that the functions are performed the same.

As shown in FIG. 17, this bottom holding capacity performs a stable function of preventing shape deformation when used as a drip filter cup for tea or coffee by placing it on a regular cup, thereby fundamentally preventing side effects of contents being overturned or tilted when used as a drip filter cup. And, since it is in a folding form, the drip filter cup can be stored and transported in a flat package, so that the flat drip filter cup can be unfolded anywhere and used as a three-dimensional filter cup.
