Description

  The present invention relates to a coaster laid under a cup, and more particularly, to a coaster that does not stick to the bottom of a lifted cup even if it is a lightweight material mainly made of paper.

  Coasters are used under the cups with drinks. The purpose of use of this coaster is to allow water droplets that have adhered to the outer surface of the cups or water droplets that have condensed on the outer surface of the cups containing cold beverages such as iced beverages to flow down from the outer surface of the cups. This is to prevent the mats such as the table surface and the table cloth laid on the table surface from getting wet. In addition, the coaster is also required to play a role as a cushioning material that softens the impact when placing cups on the table surface.

  There are various types of coaster materials such as paper, wood, cloth, rubber, resin, etc., but as a commercial coaster used in restaurants, etc., it is easy to print on the surface of the coaster, any coaster shape Paper coasters are widely used because they are easy to mold and relatively inexpensive in terms of cost.

  A paper coaster forms a coaster with a water-absorbing paper material so that water droplets flowing down from the outer surface of the cups are absorbed by the coaster surface. However, when the cups are lifted from the laid coaster, the surface of the coaster adheres to the bottom surface of the cups that are lifted through the water droplets adhering to the bottom surface of the cup or the water droplets flowing from the outer surface of the cup surface to the coaster surface. However, there was a harmful effect of sticking to the bottom of the raised cups and lifting them together. In particular, since the coaster made of paper is light in weight, even if the degree of close contact with the bottom of the raised cup is not so strong, this lifting problem is likely to occur.

  Moreover, in the flat paper coaster generally used, the buffer performance which softens the impact at the time of putting cups was inferior.

  As a coaster trying to solve the harmful effect of sticking to the bottom of lifted cups and lifting together, the bottom surface of the coaster is formed in a recess, and a function as a sucker that adsorbs the bottom surface of the coaster to the table surface is given Is known (Patent Document 1). However, the known coaster with a sucker function provided on the bottom surface of the concave portion of the coaster has a drawback that the material of the coaster is limited to a material such as rubber that can easily function as a sucker, and if the table surface is mirror-like However, if mats such as cloth table cloth made of a coarse fiber material are laid on the table surface, there is a fatal defect that the sucker function cannot be expected.

The coaster elastically deforms from a curved shape to a flat shape by its weight, and when the cups are lifted to remove the weight of the cups applied to the surface side of the coaster, the coaster is restored from the flat shape to the original shape. Since the elastic force is applied to the curved shape, it returns instantly by the coaster's own repulsive force, so when placing the cups on the coaster, it was elastically deformed from the curved shape to the flat shape due to the weight of the cups. The cups can be stably placed on the coaster, and when the cups are lifted from the laid coaster, the coaster lifts the cups at the same time as its coasting force. Since it returns instantly from the flat shape to the original curved shape and is momentarily detached from the bottom of the raised cups, it does not stick to the bottom of the raised cups and lifts together with the raised cups. Can be resolved.

  In addition, the coaster of the present invention has a curved shape that is curved in an arc shape in one direction, and a direction perpendicular to the direction is not curved but is a straight coaster surface. Therefore, the cups placed on the coaster have a flat bottom as well as the cups that have a dent in the bottom (that is, a convex peripheral edge at the bottom) that are curved in the entire circumference. Unlike the one (curved in the circumferential direction, the convex peripheral edge of the bottom is in close contact with the coaster surface over the entire circumference.) The bottom of the cup is not in close contact with the curved coaster surface. The sticking between the bottom surface of the cup and the curved coaster surface can be effectively eliminated.

  In the coaster 1 of the embodiment shown in FIG. 1 to FIG. 7, the planar shape of the coaster 1 punched into a coaster shape can adopt a round shape in addition to the illustrated substantially square shape, and is not particularly limited. However, when the planar shape of the coaster 1 is substantially rectangular as shown in the illustrated embodiment (the lengths of the corresponding sides are equal and parallel), the coaster 1 is orthogonal to the corresponding parallel sides 1a and 1a. If the coaster is curved in the direction (X-X direction) to form a curved shape that is curved in an arc shape (that is, parallel sides 1a and 1a corresponding to both ends of the coaster in the bending direction may be disposed. If the coaster 1 of the present invention formed in a curved shape is placed on the table surface F, both sides 1a, 1a are securely grounded to the table surface, and the stability performance is excellent.

  In all the embodiments shown in FIGS. 1 to 7, the coaster 1 of the present invention is formed in a curved shape that is curved in an arc shape in one direction (XX line direction). The YY line direction (the depth direction of A in each figure) perpendicular to the left and right direction of A in the figure is not curved, and the coaster surface in the YY line direction has a linear shape. Therefore, the cups G placed on the coaster 1 have a flat bottom surface, as well as the cups having a dent in the bottom (that is, having a convex peripheral edge at the bottom) are curved in the entire circumferential direction. (The curved surface of the bottom part is in close contact with the coaster surface over the entire circumference.) The cups are in close contact with the curved coaster surface. The sticking between the bottom surface of the glass and the curved coaster surface can be effectively eliminated.

To 1 cm, more preferably from 2 mm to 5 mm. In the present invention, the degree of curvature of the coaster is not limited to the above numerical value. However, if the degree of curvature of the coaster is made smaller than the above value, the effect of detaching from the raised cups will be reduced, and conversely if the degree of curvature of the coaster is made larger than the above value, the effect of detaching from the bottom of the cup However, it is necessary to increase the coating amount of each of the molten resin materials (the resin members 3, 4, and 5) that gives elastic force to the curved coaster. Therefore, the degree of curvature is determined in consideration of the separation effect and the coating amount of the molten resin material (resin member).

  The bonding molten resin material (solidified by cooling at room temperature to become the bonding resin member 3), the reinforcing molten resin material (solidified by cooling at room temperature to become the reinforcing resin member 4), and the back surface melting resin material (Solidified at room temperature to become the back resin layer 5) As a solid at room temperature, heated and melted to form an adhesive paste, coated on the adherend surface, then solidified within a few seconds at room temperature cooling At the same time, a hot melt adhesive that completes the bonding can be used.

The moisture absorbed by the front surface side coaster member 2A passes between the bonding resin members 3 of a plurality of streaks arranged apart from each other, and is further absorbed by the back surface side coaster member 2B. Therefore, the water absorption performance of the coaster can be enhanced. In addition, this invention is limited to the coaster of embodiment shown in FIGS. 1-4 in the aspect with which the surface side coaster member 2A and the back surface side coaster member 2B are adhere | attached through the joining resin member 3 solidified.

For example, the bonding resin in which both coaster members are bonded together via the bonding molten resin material in a heated and melted state spray-coated on a bonding surface of at least one coaster member, and both the coaster members are solidified in a sprayed state It does not exclude what is adhered through the member 3. However, in the case of the spray mode, if the spray coating is performed so that the innumerable liquid passage portions remain in a scattered manner, the water that has passed through the innumerable liquid passage portions is further absorbed by the back surface side coaster member 2B. It is possible to improve the water absorption performance of the coaster.

  In the coaster 1 of the embodiment shown in FIGS. 1 to 4, the surface side coaster member 2 </ b> A and the back surface side coaster member 2 </ b> B are made of paper or nonwoven fabric having water absorption, but the surface side coaster member 2 </ b> A is compared. The back side coaster member 2B is relatively thick, the front side coaster member 2A is relatively thick, and the back side coaster member 2B is relatively thin. These combinations, such as those in which the coaster members 2A and 2B are plate-like members having the same thickness, can be appropriately adopted. However, the front side coaster member 2A is a relatively thin coaster member made of a thin pulp fiber sheet having a water absorption property or a non-woven sheet, and the back side coaster member 2B is a recycled paper such as a thick liner base paper having a water absorption property. When a relatively thick coaster member made of is used, there is an advantage of enhancing the resource saving effect.

  The coaster 1 of the embodiment shown in FIG. 5 to FIG. 7 in which the coaster member 2 is composed of a single sheet uses a relatively thick one as a paper or nonwoven fabric coaster member having water absorption. For example, when a relatively thick coaster member made of recycled paper such as thick liner base paper having water absorption is used, there is an advantage of improving the resource saving effect.

  The coaster 1 of the embodiment shown in FIGS. 2 and 4 further strengthens the elastic force of the coaster by the elasticity of the curved reinforcing resin member 4 in addition to the action and effect of the coaster of the embodiment shown in FIG. it can. In addition, as shown in the figure, when the reinforcing resin member 4 having a convex shape is bonded and formed on the surface side of the coaster 1, the cups (G) placed on the coaster surface (the surface side of the surface side coaster member 2A). The reinforcing resin member 4 having a protruding shape is interposed between the bottom of the glass and the detachment performance of the cup bottom from the coaster surface can be further enhanced. The coaster of this embodiment is suitable as a coaster used when it is heavy and has a large amount of water drops, such as a mug for beer or a glass for water splitting. Also in the coaster 1 of the embodiment shown in FIG. 6 and FIG. 7, since the reinforcing resin member 4 is formed on the surface side of the coaster 1, the coaster surface (the surface side of the surface side coaster member 2 </ b> A) ) And the bottom of the placed cups (G), the protruding reinforcing resin member 4 is interposed, and the ability to remove the cup bottom from the coaster surface can be further enhanced.

  The coaster 1 of the embodiment shown in FIG. 3, FIG. 4, FIG. 5 and FIG. 7 has the back surface resin layer 5 having no moisture permeability laminated and adhered to the back surface of the coaster. It can be completely stopped by the back surface resin layer 5, and there is an advantage that water stains on the table surface and table mat on which the coaster is placed can be completely prevented.

The coaster is formed into a curved shape that is curved in an arc shape in one direction in the same direction as the extending direction of the reinforcing resin member so that the surface side of the coaster protrudes and the back surface side is recessed. Due to the elasticity of the reinforcing resin member solidified into a curved shape substantially the same as the shape, if the cups are placed on the surface side of the coaster, the coaster will elastically deform from the curved shape to a flat shape by its weight. When the cups are lifted to remove the weight of the cups applied to the surface side of the coaster, the coaster returns from the flat shape to the original curved shape by the self-repulsive force of the coaster. A featured coaster.   Reinforced molten resin material in a heated and melted state is coated on a surface of a coaster member made of paper or non-woven fabric that is punched into a planar shape of a coaster, and is applied as a plurality of spaced apart ridges extending in one direction. In addition, the entire surface of the back side of the coaster member is coated with a backside molten resin material in a heated and melted state, and these molten resin materials are solidified by cooling at room temperature, so that the surface side of the coaster member is Adhering a plurality of protruding reinforcing resin members made of reinforced molten resin material solidified, and laminating and adhering a back resin layer made of solidified back surface molten resin material to the entire back surface of the coaster member In this coaster, the entire surface of the coaster is projected in the process of solidifying the reinforced molten resin material and the back surface molten resin material, and the back surface side is recessed. In the same direction as the coating direction of the reinforced molten resin material, it is formed into a curved shape that is curved in an arc shape, and thus a plurality of ridges separated from each other on the surface side of the coaster member are solidified The reinforcing resin member is bonded and formed, and the solidified back resin layer is laminated and adhered to the entire back surface of the coaster member, and the entire coaster protrudes from the front side of the coaster and the back side is recessed. The reinforcing resin member solidified into a curved shape substantially the same as the curved shape of the coaster on a coaster formed in a curved shape that is curved in an arc in one direction the same as the extending direction of the reinforcing resin member, and the If the cups are placed on the surface side of the coaster due to the elasticity of the back surface resin layer, the coaster will elastically deform from a curved shape to a flat shape by its weight and lift the cups If rid the weight the coaster drinking glasses applied to the surface side of the coaster returns on its own repulsive force of the coaster to its original curved shape from a flat shape, coaster, characterized in that imparted an elastic force.
