Description

The present invention relates to a slit structure of the mouth and neck of a tube container capable of easily discharging contents such as toothpaste and cosmetics and using up the contents until the end.

Conventionally, a tube container is composed of a tube body, a mouth neck, and a cap, and has a structure in which the contents are extruded from the extrusion port after the cap is removed. When the contents in the container are low, it is usual practice to turn the container upside down, move the contents to the cervical side, and take out the moved contents from the extrusion port. However, with such a structure, even if the contents of the tube body can be taken out, it is difficult to take out the contents remaining in the mouth and neck.

A common home practice is to cut the tube body near the mouth and neck. Although such a cutting means can almost certainly take out the contents and use up to the end, it is troublesome to cut the tube one by one, and the cut tube is aesthetically unfavorable.

In view of the above problems, the applicant of the present application has invented a tube container capable of easily discharging the contents such as toothpaste powder and cosmetics and using up the contents until the end (Patent Document 1). This tube container is characterized by the mouth and neck, and is the mouth and neck of the tube container that is fitted to the outer circumference of the opening edge of the tube body to discharge the liquid, and is a fitting wall that fits to the outer circumference of the opening edge of the tube body. A liquid storage unit having an inner bottom surface for receiving and storing the liquid flowing from the tube body and a discharge port for discharging the liquid are provided, and a groove is provided in the center of the inner bottom surface of the liquid storage unit. The width is gradually reduced with respect to the liquid discharge direction. The groove bottom is cut in the direction of the groove length toward the tip of the discharge port, and the groove bottom is longer and wider than the cut. It is characterized in that the groove and the cut become a liquid passage from the liquid storage portion to the discharge portion so as to be wide. However, in the invention according to Patent Document 1, although the contents can be easily discharged and the contents can be used up to the end due to the structure of the mouth and neck, some contents are discharged after the contents are discharged. Remained in the cut, and it turned out that there was a problem in terms of aesthetics and hygiene.

Various inventions have been proposed for the cut or slit structure of the discharge portion of the container. The invention according to Patent Document 2 includes a valve having a structure in which the slit is opened and closed by an operation of pressurizing / releasing in the radial direction with respect to the outer circumference of the valve made of an elastic material in which the slit is cut. Slit containers have been proposed. In the invention according to Patent Document 3, it is proposed that the flat surface serving as the discharge port is formed into a shape such as a cross shape or a single character shape as a slit valve.

However, the container according to Patent Document 2 has a drawback that the structure is very complicated and the manufacturing cost increases. Further, in the slit of the container according to Patent Document 3, although the contents do not leak only by being inverted, the slit portion is removed in an attempt to remove the residue after the contents are discharged, as in the slit of Patent Document 1. When traced, the valve opens and the contents are discharged, which causes a problem that it is difficult to remove the residue.

In view of the above problems, an object of the present invention is that the contents such as toothpaste powder and cosmetics can be easily discharged and the contents can be used up to the end, and the contents remain when the contents protrude. It is to provide a tube container having a slit structure which can easily remove an object.

The slit structure of the mouth and neck of the tube container according to the present invention includes a fitting wall fitted to the outer periphery of the opening edge of the tube body, and a liquid storage portion including an inner bottom surface that receives and stores the liquid flowing from the tube body. In the mouth and neck of a tube container including a tip having a discharge port for discharging the liquid, the tip is composed of a flat surface, and the discharge port has a rectangle intersecting near the center of the flat surface. An X-shaped discharge groove is formed, and a slit is provided from the center of each short side of the rectangle to the center of the opposite short side, and the discharge groove is downward from the long side of each rectangle toward each slit. It is characterized by being inclined.

The discharge groove may have a V-shaped cross section, a U-shaped cross section, or a mortar-shaped discharge groove. Further, in the discharge groove, the depth of inclination downward from the long side of each rectangle toward each slit is preferably 0.1 to 0.2 mm.

Further, the pedestal according to the present invention is characterized in that the tube container is erected by supporting the above-mentioned mouth and neck body.
Further, the cap according to the present invention is provided with a support groove on a flat surface of a rectangular plate so that the container body can be inverted and supported by sandwiching the outer surface of the mouth and neck body described above, and the support groove is provided in the length direction. One is provided with an entrance that can be attached and detached by sliding the outer surface of the mouth and neck body, and the other end in the length direction is closed. The other end may be provided with a small protrusion at an arbitrary position on the inner surface thereof.

Alternatively, the support groove is provided with an inlet on one side in the length direction that allows the outer surface of the cervical body to be slid into and detached, and the other end in the length direction is closed to provide a tube container. It can also be used as a cap for the mouth and neck. Further, if a small protrusion is provided at an arbitrary position on the inner surface of the other end, the mouth and neck body can be prevented from coming off. Further, if the support groove is provided with a ridge pillar body at an arbitrary position in the length direction from each entrance of the inner facing surface toward the back, it is possible to prevent the mouth and neck body from coming off.

According to the present invention, when the tube is pushed out, the tube container is opened so that the slit is expanded by the contents pressurized by the pressing of the container, and the contents are discharged. In addition, when the liquid passage from the discharge groove to the cut is closed, the inflow of air or the like is prevented from the outside, and when the discharge of the contents is completed, the slit is self-closed and the contents are cut well and no dripping occurs. .. Finally, since the entire contents can be discharged, the user is given an exhilarating feeling that the contents have been used up, and since it is not necessary to cut the tube, the aesthetic appearance is not spoiled. Further, the slit structure according to the present invention makes it easy to remove the residue when the content protrudes, and by disposing a pedestal that supports the mouth and neck, it is possible to prevent the content from being discharged to the outside. At the same time, the installation location can be organized. Further, the structure of the present invention is simple and has an effect of reducing the manufacturing cost.
