Disclosed is a drinking water that not only prevents the handle from slipping due to the continuous cotton shape of the protrusions, but also prevents the protrusions from being damaged, and does not cause cracks or plastic deformation regardless of heat shrinkage associated with high-temperature sterilization disinfection. Provide a resin bottle.
In a drinking water resin bottle P which is molded of plastic and has a small-diameter mouth 3 projecting so that a screw cap is tightly fitted to the upper end of a body 1, a four-sided panel having a body having a flat surface. A rectangular tube having a surface 6, each of the lower half of the panel surface corresponding to the finger of the handle is provided with a wide recess 8 by a step, and convex portions 11 are randomly arranged in the step.

Description

  The present invention mainly relates to a resin bottle for drinking water used for marketing drinking water such as deep ocean water, natural water, mineral water, and juice and tea.

  Conventionally, this type of resin bottle has a cylindrical shape such as a cylindrical shape or a square shape that is blow-molded with a plastic material. Packaged. There are many cylindrical shapes, but they do not roll carelessly when placed down, can be packed efficiently in a space, are easy to hold without slipping, and contents after high-temperature sterilization disinfection Square cylinders tend to be frequently used because they are easily adapted to heat shrinkage.

  As the plastic material, polyethylene, polypropylene, polystyrene, vinyl chloride resin and the like are used. Recently, however, bottles made of PET (thermoplastic polyester) have dramatically increased. This is because the PET bottle has a particularly excellent aspect in that it has low hardness but is not sticky and does not break, and can be reduced in weight by reducing its thickness. However, it is soft and easily damaged, and high temperature sterilization has disadvantages such as deformation of the material.

  With regard to the point of being easily damaged, especially when a rough surface is provided on the outer peripheral surface so that the hand does not slip, the convex part is easy to touch other objects, and the tip part is rubbed and faded. It was an obstacle.

  For high-temperature sterilization, in the case of deep sea water or mineral / natural water, it is heated at a temperature close to 100 ° C after bottling and then sealed with a screw cap while maintaining the heating temperature. Therefore, if the resin bottle is plastically deformed due to thermal shrinkage when the contents cool down, or if the resin bottle itself shrinks, there is a structural part in which the shrinkage is not absorbed on average due to the shape. There is a problem that cracks may occur due to concentration on the surface.

  In view of the above situation, this device not only prevents the handle from slipping due to the continuous cotton shape of the convex portion, but also prevents the projection from being damaged, and regardless of the heat shrinkage associated with high temperature sterilization disinfection. It was made into the subject to provide the resin bottle of the drinking water which a crack and plastic deformation do not produce.

  In order to solve the above-mentioned problem, in this resin bottle of drinking water, which is molded from plastic and has a small-diameter mouth projecting so that a screw cap is tightly fitted to the upper end of the body, the body is flat. It is a rectangular tube shape with four panel surfaces, and each of the lower half of the panel surface corresponding to the finger of the handle is provided with a wide recess in the step, and the protrusions are randomly in the step. Provided is a resin bottle of drinking water characterized in that the rough surface to be arranged is formed, and each convex part is formed lower than the virtual surface with the panel surface.

  Since the resin bottle for drinking water is configured as described above, the rough surface is provided in a low recess with a step, so it can be stably hung so that it does not slip and come off by dropping your finger there. Also, because the convex part is lower than the virtual surface with the panel surface, it is difficult to touch other objects, and the uneven rough surface is a random arrangement of convex parts, so it is free It is easy to deform.

  As described above, according to the drinking water resin bottle of the present invention, the handle is not slipped by the random-like arrangement of the convex portions and the concave portions thereof, and the drinking operation can be performed safely. The product display effect is effectively retained in combination with the design effect of the convex arrangement, and the heat shrinkage associated with high-temperature sterilization is absorbed by free deformation of the rough surface. Therefore, there is an excellent effect that the commercial value can be maintained aesthetically without causing cracks or deformation.

  The drinking water resin bottle P is manufactured by blow molding or the like of a plastic material using polyethylene, polypropylene, polystyrene, vinyl chloride resin, PET (polyethylene terephthalate), or the like. About the Example, it blow-molded using PET.

  FIG. 1 to FIG. 5 show an embodiment, and the resin bottle P of the drinking water has a barrel 1 as a main body having a rectangular tube shape (an octagonal tube shape because each corner of the square is taken). And a male screw is formed in which the screw cap 5 is screwed into the upper end opening portion 3, and each surface of the body portion 1 is formed on a flat panel surface 6. An annular groove 4 is provided, and a recess 8 is provided on each panel surface 6 in the lower half below the annular groove 4. The recess 8 is formed on the rough surface 10.

  The rough rough surface 10 has a shape in which a large number of convex portions 11, 11,... Are formed as continuous cotton inside the respective steps 9, and in this case, it resembles a flat pattern in which ice is randomly broken. In addition, since each convex portion 11 has a cut surface that resembles a jewel, the inside of the frame of the step 9 irregularly reflects light on the rough rough surface 10, which attracts the attention of a person. Focusing on this diffuse reflection effect of light, we decided to call it a crystal pattern (or an ice pattern or a gravel pattern). However, the rough rough surface 10 is not limited to a crystal pattern or the like, and can be freely and creatively formed by randomly arranging straight lines, curved lines, curved surfaces, and planes.

  For example, as another shape of the rough rough surface 10, in FIG. 6, a polka dot pattern in which the convex portions 11 are arranged at intervals like a polka dot, and in FIG. Each of the marble patterns represented as the convex portions 11 is shown.

  In any case, since the convex portion 11 has a shape lower than the virtual flush surface 6a having the same height as the panel surface 6 in the recess 8 which is lower than the step 9, the panel surface 6 becomes an obstacle and other Opportunities to touch things are greatly reduced. Moreover, even if it touches, it will become a light touch, there is no possibility of being damaged, and the beauty | look as a product can be kept safely.

  If the inside of the step 9 is a plane, the freedom of deformation of the plane is constrained by a uniform plane, so stress concentrates on one point and cracks easily occur from there. In No. 10, straight lines, curved lines, curved surfaces, and planes are randomly arranged and freely deformable, so that heat shrinkage is absorbed and cracks do not occur.

  On each panel surface 6 above the annular groove 4, three upper, lower, and lower lateral grooves 7, 7, 7 are formed and, together with the annular groove 7, function as a rib and absorb heat shrinkage.

It is a front view which shows the resin bottle of the drinking water as one Example of this device. It is sectional drawing of the AA arrow of FIG. It is sectional drawing of the BB line arrow of FIG. It is an expanded sectional view of the CC line arrow of FIG. It is a top view of the resin bottle of the same drinking water.
