JP4952316B2 - Packaging tube - Google Patents

Description

  The present invention relates to a packaging tube that contains toothpaste and the like. More specifically, the present invention relates to a packaging tube that can use a contained toothpaste and the like in a necessary amount without waste.

  Patent Documents 1 and 2 disclose packaging tubes that contain toothpaste and are provided with a narrow rectangular outlet.

According to Patent Document 1, the toothpaste squeezed out from the circular squeeze outlet has a round bar shape, and therefore has a small contact area with the toothbrush surface and is likely to fall off. By making the constriction outlet rectangular, the contact area between the toothpaste and the brush surface is increased, and it is difficult to drop off.
Further, if the rectangular cross-sectional area is set smaller than the circular cross-sectional area, the amount of use when toothpaste having the same length is squeezed out can be reduced.

In Patent Document 2, a cylindrical protruding portion is provided at one end of the packaging tube, and an elongated slit-shaped throttle outlet is formed on the side surface of the protruding portion.
Contained items (toothpaste, etc.) are squeezed out from the slit-shaped squeezing outlet in small amounts, making it easy to determine the amount to be used, making no waste, and dumping in the form of dumplings. Absent.

  The present invention is basically intended to use the contents without waste as in Patent Documents 1 and 2, but provides a packaging tube having a further advanced structure.

  The packaging tube of the present invention includes a throttle outlet for squeezing out the contents. The throttle outlet has a measuring plate that has “a long and narrow opening including two long sides facing each other” and protrudes from one long side.

According to the packaging tube of the present invention having the above-described configuration, the “metering plate dimension” and the “opening height of the throttle outlet (that is, the distance between two long sides)” are set to appropriate values. An appropriate amount of content is always squeezed out on the weighing plate.
Therefore, the necessary amount of content is consumed, and waste can be saved.

  Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view showing a packaging tube according to an embodiment of the present invention.

  The packaging tube of the present invention includes a throttle outlet 20 at one end of a tubular tube body 10. Although not shown, the other end is sealed by heat sealing or other appropriate methods.

  2A shows a longitudinal sectional view of the main part of the packaging tube with the cap 30 attached, and FIG. 2B shows an end view of the packaging tube with the cap 30 removed.

  As best shown in FIG. 2 (b), the throttle outlet 20 has an elongated rectangular opening 22 having two long sides 25 and 26 and short sides 35 and 36 facing each other. One long side 26 extends so as to protrude upward in FIG. 2A to constitute a measuring plate 28.

  The measuring plate 28 is used as shown in FIG. That is, the toothpaste 5 is squeezed out onto the measuring plate 28 by holding the packaging tube so that the measuring plate 28 is positioned on the lower side. By setting the dimensions of the measuring plate 28 and the height of the rectangular opening 22 of the restricting outlet 20 (that is, the distance between the long sides 25 and 26) to appropriate values, it is always appropriate on the measuring plate 28. An amount of toothpaste 5 will be squeezed out.

An example of the dimensions is as follows.
(1) Dimensions of measuring plate 28: 9 mm × 14 mm
(2) Distance between long sides 25 and 26: 10 mm

  However, the measuring plate 28 does not necessarily need to be rectangular, and the shape can be appropriately determined such as a semi-elliptical shape or an irregular shape.

In the illustrated example, the measuring plate 28 protrudes from the long side 26 of the two long sides 25, 26, but the measuring plate may protrude from any long side.
Further, the opening of the throttle outlet 20 does not have to be rectangular as shown in the figure as long as it is substantially elongated. For example, the short sides 35 and 36 may be curved, or may be an elliptical opening having no clear short sides 35 and 36. Further, the long sides 25 and 26 do not need to extend linearly and may be appropriately curved.

The perspective view which shows the packaging tube which concerns on one Embodiment of this invention. The principal part sectional drawing and end elevation of the packaging tube of FIG.
