The present invention relates to an asymmetric tube container, the outlet side, which is a portion adjacent to the outlet of the tube container is formed so that the cross section is elliptical shape, and the distal end located in the opposite direction to the outlet side is formed on one plane, By forming the angle formed by the plane of the end portion within 90 degrees to improve the content ejection performance and to facilitate gripping.

The conventional structure of the tube container made of synthetic resin was to allow the contents to be discharged and the ends extending in one direction from the discharge ports are joined on one plane to store the contents. Holding the tube container in his hand and pressing the tube container using a thumb or the like was to discharge the contents.

However, the conventional tube container is formed in a symmetrical structure in which the contents are stored, and there is a limit in that pressure is applied only to a local part when the container is pressed with a finger to discharge the contents.

The present invention has been invented to provide a new tube container which is different from the conventional tube container structure described above, and an object of the present invention is a closed end portion formed on an outlet side and an outlet side on which the outlet is formed and opposite to the outlet side. A tube container having, the outlet side is formed in an elliptical cross section, the distal end is formed on one plane, and the major axis of the ellipse in the outlet side cross section has an angle within 90 degrees with respect to the one plane on which the distal end is formed. It is to provide an asymmetric tube container, characterized in that forming.

An object of the present invention described above has a discharge portion on which an outlet through which contents are discharged is formed and a storage portion having a closed end portion formed on an opposite side to the discharge side, and on one plane parallel to a plane perpendicular to the direction from the distal end toward the discharge opening. The cross section of the outlet side of is a closed curve having a long axis and a short axis, and a projected straight line projecting a projected long axis projecting the long axis on the one plane and a straight line connecting both ends of the distal end onto the one plane. The acute angle formed by the projected long axis and the projected straight line intersecting with each other, is achieved by an asymmetric tube vessel, characterized in that it is greater than 0 degrees and less than 90 degrees.

In order to achieve the above object, the acute angle formed by the projected long axis and the projected straight line is preferably 20 to 70 degrees.

In addition, in order to achieve the above object, the closed curve preferably includes an ellipse.

In addition, in order to achieve the above object, the length from the outlet to the distal end of the tube vessel is preferably 6 to 15 centimeters.

In addition, in order to achieve the above object, the material of the asymmetric tube container is preferably a synthetic resin.

Other objects, specific advantages and novel features of the invention will become more apparent from the following detailed description and the preferred embodiments associated with the accompanying drawings.

Hereinafter, with reference to the accompanying drawings will be described in detail asymmetric tube container according to a preferred embodiment of the present invention.

As shown in Figures 1 to 4, an asymmetric tube container according to a preferred embodiment of the present invention largely includes a reservoir 20 and a lid 10.

Storage portion 20 is a portion for receiving the contents to be stored in the tube container is formed with an outlet 21 at one end and the distal end 29 is formed at the other end and the outer wall surface (between the outlet 21 and the distal end 29) 27) is formed.

Discharge port 21 is a structure that protrudes upward and the discharge hole 22 is formed at the upper end and the thread is formed on the periphery can be combined with the cover 10. The lower end of the outlet 21 is connected to the outlet support 25. The outlet support 25 is an elliptical surface formed substantially perpendicular to the outlet 21 to support the outlet 21 and similar to the area of the lid 10 so that the lid 10 can be positioned when the lid 10 is covered. Has an area.

The outer wall surface 27 is formed below the outlet support part 25.

The outer wall surface 27 extends continuously below the outlet support 25, and the outer wall surface 27 has a shape that is continuously twisted from the upper end to the lower end. In other words, it has an asymmetrical structure in any direction. A portion of the outer wall surface 27 adjacent to the outlet support part 25 is called 'outlet side'. Since the outer wall surface 27 extends downward from the edge of the outlet support 25 which is an elliptical surface, the 'outlet side cross section adjacent to the outlet support 25' becomes elliptical. As shown in FIG. 4, the 'outlet side end surface adjacent to the outlet support part 25' means a cross section on one plane S parallel to a plane perpendicular to the direction from the distal end 29 toward the outlet port 21. it means. The one plane (S) is parallel to the plane (not shown) where the ellipse formed by the circumference of the elliptical surface of the outlet support 25 is located.

As shown in FIG. 5, a straight line L1 connecting the both ends of the distal end and the projected long axis M projected on the one plane S to project the long axis of the ellipse, which is an outlet side cross section, into the one plane ( The projected straight lines L2 projected onto S) intersect to form a predetermined angle to each other. Here, the straight line L1 and the projected straight line L2 connecting both ends of the distal end are located on one plane to which the distal end described later is joined.

The angle at which the projected long axis M and the projected straight line L2 must be made to form the tube vessel into an asymmetrical structure is characterized by the torsional moment and Since the number of working points of the force must be increased, it is required to be at least larger than 0 degrees and smaller than 90 degrees, preferably 20 to 70 degrees, and more preferably 30 to 60 degrees.

The lower end of the outer wall surface 27 is formed with a distal end 29. The distal end portion 29 has a structure in which the end portions of the outer wall surface 27 are closely adhered in both directions and are bonded on one plane, thereby blocking one end portion of the outer wall surface 27 so as to store contents in the storage portion 20. The end portion 29 is formed by a method such as thermocompression bonding.

Method for producing an asymmetric tube container according to a preferred embodiment of the present invention described above is as follows.

The process of manufacturing the asymmetric tube container of the present invention is similar to the process of manufacturing a conventional tube container, except that the process of forming the distal end 29 is different.

Since a process for manufacturing a conventional tube container is obvious to those skilled in the art, a description thereof will be omitted here, and a process for forming a distal end portion 29 which is different from the conventional process will be described.

The process of forming the distal end portion 29 by thermocompression in order to have a predetermined angle on the one plane on which the outlet support 25 and the distal end portion 29 are formed is as follows. When the two press molds approach the one plane on both sides of the outer wall surface 27, and the ends of the outer wall surface 27 are brought into close contact with each other, the tubes are overlapped in two layers and the end portions 29 are formed. In the press process for forming the distal end 29, the outlet support 25 of the tube container is fixed in position. At this time, in order to form the tube container in an asymmetrical structure, the outlet support portion 25 is fixed by arranging the outlet support portion 25 so that one plane formed by the oval long axis of the outlet support portion 25 is in close contact with the press to form a predetermined angle. do. When press thermocompression is performed while the outlet support part 25 is fixed, the tubular container is formed in an asymmetrical structure while the elliptical long axis of the outlet support part 25 forms a predetermined angle with one plane formed by the press being in close contact. That is, as shown in Fig. 5, the two presses in the state in which the outlet support is fixed so that the major axis A of the ellipse of the outlet support of the tube container forms a predetermined angle with the one plane C on which the distal end is formed. It is to perform a thermocompression process in which the mold is brought into close contact with the one plane C.

As shown in Figs. 6 and 7, when the finger grips the asymmetric tube container and presses it with a finger, the force applied by the index finger and the thumb applied in both directions of the tube container act on two lines separated from each other. Each of the forces acting on the asymmetric tube vessel outer wall surface 27 by the index finger and thumb is the component of the force in the direction toward the center of rotation of the asymmetric tube vessel and the center of rotation, as described in Equation 1 below. It can be divided into the component of the force in the direction perpendicular to the direction.

F ₁ = P ₁ + T ₁ , F ₂ = P ₂ + T ₂

Therefore, the forces (P ₁ , P ₂ ) in the direction toward the center of rotation press the asymmetric tube vessel, and the forces (T ₁ , T ₂ ) in the direction perpendicular to the direction toward the center of rotation cause the torsional moment to the asymmetric tube vessel. Act.

As a result, as shown in Figs. 8 and 9, the asymmetric tube container is accompanied by a deformation D ₁ due to the compressive force and a deformation D ₂ due to the torsional moment at the same time, so that the deformation larger than that when only the compression force is applied. In other words, the volume reduction is greater.

The forces acting on the outer wall surface 27 of the asymmetric tube vessel can also be seen to act on four points, as shown in FIG. 10. Since the forces acting on both sides of the asymmetric tube vessel act on two different lines, considering the forces and reaction forces generated by each of the forces acting on the two lines, pressing the asymmetric tube vessel at four points It can be seen as. As a result, deformation D ₃ occurs.

In the case of the conventional symmetrical tube container, the forces acting on the outer wall surface 27 of the symmetrical tube container are generated by the force acting on one line, since they act on one line, as shown in FIG. Considering the applied force and reaction force can be seen to press the symmetrical tube vessel 30 through two points and the resulting deformation (D ₄ ) is smaller than the deformation shown in FIG.

Pressing four points rather than pressing two points results in a larger deformation of the tube vessel.

The discharge of the contents stored in the tube container is proportional to the deformation amount of the tube container when the tube container is pressurized, so that the larger the tube container is deformed, that is, the larger the volume reduction of the tube container, the larger the discharge of the content. .

As described above, the asymmetric tube container according to the present invention provides a compressive force and a torsional moment simultaneously due to the asymmetrical structure, and the number of working points of the force acting on the outer wall surface 27 of the container is increased to reduce the deformation amount of the tube container. Since it is increased, the discharge performance of the contents is greatly improved.

In addition, since the asymmetric structure of the asymmetric tube container according to the present invention corresponds to the asymmetrical internal space of the hand formed when the human hand is held, the grip of the asymmetric tube container becomes stable.

The material of the asymmetric tube container according to the present invention may use synthetic resins typically used in tube containers. The asymmetric tube container of the present invention exerts an effect on the synthetic resin material, and the effect is difficult to be exhibited in the metal tube container. This is because the metal tube container does not return to its original shape even if it is pressurized and released.

In addition, by forming the distal end 29 of the asymmetric tube container according to the present invention from 6 to 15 cm from the distal end 29, the user can hold the entire asymmetric tube container in the user's hand, so that the stability of the grip is optimal. It will help to improve the emission performance.
