The bottle that content is housed involved in the present invention is, in content is sealed in the bottle that content is housed in the bottle, it is characterized by, and described bottle is a bottle of the present invention, presses in the bottle simultaneously to be higher than barometric pressure.
According to such feature, because the inside part of horizontal bar is rounded in cross-sectional apparent time, when therefore being pressed into malleation in bottle, horizontal bar is less and distortion equably on full week.That is, inside part at the deflection of the rounded horizontal bar of cross-sectional apparent time less than the maximum deformation quantity of the horizontal bar that is quadrangle (square) in cross-sectional apparent time (deflection) in the central portion office on each limit.Therefore, by this horizontal bar, can suppress effectively to press in the bottle cause be the roughly distortion at each main part face place of foursquare main part in cross-sectional apparent time.In addition, by longitudinal rib, can be suppressed at main part main part face place to radially the distortion that bloats.
In addition, the bight at four angles of the preferred described main part of bottle involved in the present invention cross-sectional apparent time form to radial outside protrude circular-arc.
Thus, the stress that concentrates on the main part face of main part obtains relaxing, can be suppressed at the deflection of central portion office of each main part face of the main part of cross-sectional apparent time, diminish in the deflection at the place, bight of main part and difference at the deflection of the central portion office of each main part face of main part.
In addition, the interior pressure of the preferred bottle of the bottle that content is housed involved in the present invention is for below the above 0.8MPa of 0.2MPa.
Thus, above-mentioned action effect then proves effective effectively.

Below, the certification testing of above-mentioned action effect is described.
Adopted as a comparison case at the bottle 1 shown in Fig. 1 and Fig. 2, adopted at the bottle 101 shown in Fig. 3 and Fig. 4, adopted the bottle that in the bottle 1 of Comparative Examples, on main part 2, does not have horizontal bar 22 as conventional example as embodiment.Each bottle of these Comparative Examples, embodiment and conventional example adopted the size that is filled with the 500ml content.
And, calculated in just applying external diameter increment rate when pressing 0.5MPa (below be referred to as the front external diameter change) by simulation at the Width middle body on the main part face to each bottle, and the internal volume increment rate of bottle (below be referred to as volume change).
Its result is aspect the external diameter variation of front, with respect to 13.4% of conventional example, Comparative Examples is 4.0% (conventional example 29.9%), embodiment is 1.5% (conventional example 11.2%), confirms with conventional example and compares, and Comparative Examples and embodiment can reduce the front external diameter and change.
In addition, aspect volume change, with respect to 6.7% of conventional example, Comparative Examples is 3.8% (conventional example 56.7%), embodiment is 4.9% (conventional example 73.1%), confirms with conventional example and compares, and the volume change of Comparative Examples and embodiment further is inhibited.
More than, though be illustrated for Fig. 1, bottle 1 shown in Figure 2 and Fig. 3, bottle 101 shown in Figure 4, the present invention is not limited to above-mentioned embodiment, can suitably change in the scope that does not break away from its aim.
For example, in above-mentioned Fig. 1, bottle 1 shown in Figure 2, though the outside of the middle body 24 of the outside of the inside part 23 of horizontal bar 22 and the main part face 21 of main part 2 is formed on on the one side, but the present invention also can be the outside of the inside part 23 of horizontal bar 22 to be compared with the outside of the middle body 24 of the main part face 21 of main part 2 and more is positioned at radially inner side, and horizontal bar 22 is the shape that is recessed in week entirely.
In addition, in above-mentioned Fig. 3, bottle 101 shown in Figure 4, though the middle body at the Width of main part face 21 is equipped with longitudinal rib 125, but the present invention also can be the position beyond the middle body of the Width of main part face 21 is formed with longitudinal rib 125, for example, also can be formed with longitudinal rib respectively in the both sides of the Width middle body of main part face 21.
In addition, in above-mentioned Fig. 3, bottle 101 shown in Figure 4, though longitudinal rib 125 extends the lower end (upper end of bottom 3) that is set to main part 2 from the upper end (lower end of shoulder 4) of main part 2, but can suitably change the length of longitudinal rib 125, also can only be formed with longitudinal rib on the axial part of main part 2, perhaps, the outer peripheral face that is set to shoulder 4 also can be extended in the upper end of longitudinal rib, perhaps, the outer peripheral face that is set to bottom 3 also can be extended in the lower end of longitudinal rib.For example, if the outer peripheral face that is set to bottom 3 is extended in the lower end of longitudinal rib when the outer peripheral face that is set to shoulder 4 is extended in the upper end of longitudinal rib, then in just, press when acting on main part 2, main part face 21 can be further suppressed to the radial outside distortion, the face shaping of main part 2 quadrangle can be held in more effectively.
In addition, in the scope that does not break away from main idea of the present invention, inscape in the above-described embodiment suitably can be replaced to known inscape, in addition, also can suitably make up above-mentioned variation.
