Description

Quantitative spray extrusion container

The present invention relates to a quantitative discharge extrusion container, and more particularly to a quantitative discharge extrusion container having a pressing operation portion for discharging a content liquid in a specific amount.

The squeezing container is formed by manually holding and pressing (pressing) the main body portion of the container body formed of plastic capable of extrusion deformation, so that the container body is pressed and deformed, and the content liquid is ejected from the ejection outlet to the ejection portion. Spray in a specific amount. Moreover, a so-called quantitative ejection squeeze container has been developed, which is designed such that when the main body portion of the container body is squeezed, the deformation amount of the container does not vary, and each extrusion is repeated. In the operation, a fixed amount or a substantially fixed amount of the content liquid is ejected (for example, refer to Patent Document 1 and Patent Document 2).

In the quantitative discharge extrusion container of Patent Document 1 or Patent Document 2, since it is necessary to attach an abutting member inside the container body or to cover a peripheral wall of the container body to mount a tubular cover body having a bridge portion, the structure is complicated. And the manufacturing cost also increases. In view of this situation, the applicant of the present invention developed a quantitative discharge extrusion container by looking for the trick from the shape of the container body, which is not subject to the difference in the amount of deformation of the container body during the repeated pressing operation. In this way, the content liquid can be ejected at a fixed amount each time (for example, refer to Patent Document 3 and Patent Document 4).

The present invention is a quantitative discharge extrusion container having a pressing operation portion that presses and deforms at least a portion of the container body to eject a content liquid from a discharge port by a specific amount. The pressing operation portion is provided at an intermediate portion in a lower direction of the main body portion of the container body. The pressing operation portion has a press face. At least one of an upper portion and a lower portion of the press surface is formed with a deformation suppression reinforcing portion.

The quantitative discharge squeeze container of Patent Document 3 or Patent Document 4 includes a press surface portion having a mountain-shaped cross section including one pair of inclined surface portions along two surfaces intersecting at an intersecting angle of an obtuse angle. Further, in the quantitative discharge extrusion container of Patent Document 3 or Patent Document 4, when a finger is pressed against the top of the mountain-shaped cross section of the press face and pressed, the pair of inclined surface portions are deformed so as to expand the intersecting angle, and both sides are expanded. The interval between the crotch portions of the mountain-shaped cross section is limited such that the pressing surface is not reversed to the valley shape after the bevel is deformed until the expansion force disappears. Thereby, it is possible to cause the difference in the amount of extrusion deformation of the container body caused by the pressing operation which is repeated, so that the content liquid is ejected at a fixed amount each time.

On the other hand, in such a quantitative discharge extrusion container, if the capacity of the container body becomes a relatively large capacity of, for example, 800 mL or more, the deformation at the time of deformation of the extrusion operation portion is easily performed by the pressing operation. Squeeze around the operating part. Therefore, it is considered that a difference in the discharge amount of the content liquid is likely to occur, and in view of the above, it is desired to effectively suppress the extrusion of the pressing operation portion particularly when the capacity of the container body is set large. The deformation of the time and the surroundings are such that the content liquid is ejected at a fixed amount each time in a state where the difference is less stable.

The deformation suppression reinforcing portion may be provided at an upper portion of the press surface, or may be provided at both the upper portion and the lower portion.

Further, the press surface provided in the pressing operation portion does not necessarily need to be in the form shown in Figs. 1, 2(a) and 3, for example, as shown in Figs. 6(a) and 6(b). It may also be a press surface of various other forms which can be deformed by extrusion (pressing) so that the content liquid is ejected in a specific amount. In the quantitative discharge extrusion container shown in FIGS. 6(a) and 6(b), the pressing operation portion 14 also has a cross-sectional shape including a press surface portion 15 and a press support portion 19 via a press support portion 19 The connecting portion 18 is integrally formed integrally with the crotch portion 17 of the mountain-shaped cross section of the press surface portion 15, and is disposed to face the press surface portion 15. In the press surface portion 15 shown in Fig. 6(a), a linear flat surface is formed as a top portion 20 of a mountain-shaped cross section in the circumferential direction, and at a specific position 20a of the top portion 20, a press is formed to press against a finger. The convex part. In the press surface portion 15 shown in Fig. 6(b), the width of the top portion 20 is narrowed as it goes upward, and the slope portion 15a of the mountain-shaped cross section of the press surface portion 15 is joined to the top portion 20 whose width is narrowed upward.

Example

Hereinafter, the quantitative discharge extrusion container of the present invention will be described in more detail by way of examples and comparative examples, but the present invention is not limited by the description of the following examples and comparative examples.

[Example 1, Comparative Example 1]
The following container is used as the quantitative ejection container of the first embodiment, that is, the nozzle portion of the container body shown in Fig. 1 is provided with a discharge nozzle portion as described in Japanese Laid-Open Patent Publication No. 2011-143971. The cover member has the same configuration as the quantitative discharge squeeze container of the above embodiment. A container having the same configuration as that of the quantitative discharge container of Example 1 except for the deformation suppression reinforcing rib except for the lower portion of the lower portion of the press face was used as the quantitative discharge extrusion of Comparative Example 1.

In the quantitative discharge extrusion container of Example 1, the container system was formed by adding an elastomer to the polypropylene as a resin as an additive, and the content was about 850 mL. Moreover, the filling rate of the content liquid is about 80%. The deformation suppression rib has a groove width of 3 mm and a groove depth of 1.5 mm, and the distance between the ribs (the distance between the centers of the grooves) is 13 mm. Similarly, the rigid reinforcing ribs provided at the press support portion have a groove width of 3 mm and a groove depth of 1.5 mm, and the distance between the ribs (the distance between the centers of the grooves) is 13 mm. The deformation suppression reinforcing ribs are disposed at equal intervals from the rigid reinforcing ribs.

[Difference between average discharge amount and discharge amount]
The five test subjects were each used to measure the discharge amount of the content liquid in each of the ten extrusion operations using the quantitative discharge squeeze container of Example 1 in which the content liquid was stored and the quantitative discharge squeeze container of Comparative Example 1. Calculate the average discharge amount. Based on the average discharge amount of each of the five subjects, the average discharge amount of the entire mother set was calculated, and the maximum average discharge amount and the minimum average discharge amount were calculated, and the difference in the overall mother set was plotted. The temperature at the time of the measurement was room temperature, and the content liquid liquid lotion was used, and the product name was "Attack Neo Antibacterial Ex W power" (manufactured by Kao Corporation). The value of the calculated discharge amount is a relative value when the standard discharge amount (design value) is 100%. The calculation results are shown in Fig. 5.

It is found that, according to the calculation results of the average discharge amount and the difference shown in FIG. 5, in the quantitative discharge squeeze container of Comparative Example 1, the amount of the content liquid which is larger than the designed standard discharge amount is ejected, and the difference in the discharge amount is In contrast, according to the quantitative discharge extrusion container of the first embodiment of the present invention, the content liquid close to the designed standard discharge amount can be ejected, and the difference in the discharge amount is also small. As a result, according to the quantitative discharge extrusion container of the first embodiment of the present invention, the content liquid can be ejected at a fixed amount each time in a state of being more stable than the quantitative discharge extrusion container of Comparative Example 1.

[Measurement of deformation amount of container body]
The container body was pressed while the top of the press face was pressed until the deformation of the press face was restricted in a state where the quantitative discharge squeeze container of Example 1 and the quantitative discharge squeeze container of Comparative Example 1 were empty. The amount of deformation in the direction. The deformation amount of the pressing direction of the container body is determined on the extension line below the top of the pressing face portion in the lower region below the grip region portion, and is about 85 mm from the bottom surface of the container body (Fig. 2(a) - (c) The deformation of the lower middle side suppresses the position adjacent to the lower side of the reinforcing rib 16). The amount of deformation was measured by using a digital vernier caliper and sandwiching the front and back portions, and measuring the length in the depth direction D. The difference between the measured value in the state in which the pressing operation is not performed and the measured value in the state in which the pressing operation is being performed is the amount of deformation in the pressing direction.

The amount of deformation in the pressing direction was 3.2 mm in the quantitative ejection container of Comparative Example 1, whereas the quantitative ejection container according to Example 1 of the present invention was 2.0 mm, which was more quantitative than that of Comparative Example 1. In terms of the amount of deformation of the pressure vessel, the amount of deformation is reduced by about 40%. As a result, it has been found that the quantitative discharge extrusion container according to the first embodiment of the present invention can effectively suppress the deformation and the surrounding of the pressing operation portion when the extrusion operation portion is pressed by providing the deformation suppression reinforcing portion.
