Definitions
- the present invention relates to a synthetic resin bottle type container manufactured by biaxially stretch-blowing a synthetic resin such as polyethylene terephthalate.
- the present invention relates to deformation of the shape of the container, particularly to displacement of a vacuum absorption panel. It is intended to more advantageously avoid the deformation of the shoulder portion of the container.
- Containers made of synthetic resin, such as PET bottles, are lightweight and easy to handle, and have an appearance comparable to that of glass containers because they can ensure transparency.
- beverages, seasonings, alcoholic beverages, and detergents have been widely used as containers for filling chemicals and the like because of their low cost.
- this type of container has been improved in heat resistance so that relatively high-temperature contents that have been subjected to high-temperature sterilization or the like can be directly filled into the container without cooling. I'm making it. '
- the shape of the container is inevitable due to the pressure reduction effect when the contents are cooled to room temperature.
- the shoulder portion is originally apt to become thinner and has an insufficient strength, such as the trunk, where it is difficult to give a sufficient elongation ratio. It is.
- a step should be provided at the shoulder of the container and a triangle extending from this to the body.
- a blow molded container to which a polyhedron composed of panels is applied is known (for example, see
- the present invention relates to a shoulder connected to a mouth for discharging a content, and a shoulder which forms a space for filling the content in a region extending to the bottom wall.
- a synthetic resin bottle-type container having a reduced-pressure absorption panel defined by at least one groove having the body concave toward the inside of the container,
- a synthetic resin bottle-type container characterized in that a groove extending along the groove and having a groove depth deeper than the groove is provided in a groove located immediately below a shoulder of the reduced-pressure absorbing panel. It is.
- the recess has a width equivalent to that of the groove.
- the recess has an inclined surface for preventing shrinkage which is inclined from the outer wall toward the groove bottom.
- FIG. 1 is a diagram showing an embodiment of the container according to the present invention.
- FIGS. 2, 3, and 4 are a side view, a plan view, and a bottom view, respectively.
- FIGS. 5a, 5b and 5c are a front view, a longitudinal sectional view and a cross-sectional view of the decompression absorption panel 5, respectively.
- FIGS. 6a, 6b and 6c are a front view, a longitudinal sectional view and a cross-sectional view of the decompression absorption panel 6, respectively.
- FIGS. 7a, 7b and 7c are a front view, a longitudinal sectional view and a cross-sectional view of the decompression absorption panel 7, respectively.
- FIGS. 8a, 8b and 8c are a front view, a longitudinal sectional view and a cross-sectional view, respectively, of the decompression absorption panel 8.
- FIG. ' is a front view, a longitudinal sectional view and a cross-sectional view, respectively, of the decompression absorption panel 8.
- FIG. 9 is an external view of a container as a reference example.
- FIG. 10 is a diagram showing another embodiment of the container according to the present invention.
- FIGS. 1 to 4 are views showing an embodiment of the present invention as a bottle-shaped container having a square cross section and a waist, wherein reference numeral 1 denotes a mouth for discharging contents, and 2 denotes a mouth.
- the shoulder 3 connected to the mouth is the body forming a space for filling the contents in the region from the shoulder 2 to the bottom wall of the container.
- the body 3 has a pair of long side walls 3a facing each other, a pair of short side walls 3b also facing each other, and four corner walls 3c connecting the walls 3a and 3b to increase the buckling strength of the container. It has a square cross-section in which and are integrally formed.
- Reference numeral 4 denotes a waist portion for reinforcing the body 3 into two parts at the top and bottom
- 5 denotes a decompression absorption panel provided at the upper part of the long side wall 3a
- 6 denotes a lower part of the long side wall 3a.
- the vacuum absorbing panel, 7 is a vacuum absorbing panel provided above the short side wall 3b
- 8 is a vacuum absorbing panel provided below the short side wall 3b.
- Panels 5 to 8 are sectioned by grooves M with the body 3 recessed into the container as shown in Figs. 5a, 5b, 5c to 8a, 8b, 8c, respectively. When the pressure is reduced, each panel is displaced toward the inside of the container to prevent the container from being deformed.
- reference numeral 9 denotes a recess along the upper end groove M of the decompression absorption panel 5 (the groove located immediately below the shoulder), the groove M further having a depth of 1; and a depth t (see FIG. 5b). It is.
- FIG. 9 shows a rectangular container having a cross section similar to that of the container shown in FIGS. 1 to 4 above.
- This type of container has a large area, especially on the long side wall, so that the shoulder tends to be locally deformed due to the displacement of the panel due to the absorption of reduced pressure, which can cause a reduction in product yield. Had become.
- the upper end groove M of the vacuum absorption panel 5 is provided with the concave portion 9 having a depth t deeper than the groove, so that the rigidity of the portion is increased and the shoulder portion 2 is formed. There is no easy deformation.
- the width of the concave portion 9 is set to be equal to the width of the groove for forming the reduced-pressure absorption panel in consideration of the moldability of the container.
- FIG. 10 shows another embodiment of the container according to the present invention.
- an inclined surface S inclined from the outer wall 9a of the recess 9 toward the groove bottom is provided to prevent shrinkage during blow molding.
- the container according to the present invention shown in Figs. 1 to 5 having a capacity of 1.5 liters (resin usage: 55 g, depth of a groove for forming a decompression absorption panel 1.5 mm, width 7 mm, recess 9
- the container has the same capacity as that of 4.5 mm deep and 7 mm wide, and has the same capacity as the container shown in Fig. 9 (55 g of resin used, depth of the groove forming the vacuum absorption panel 1.5 mm, width 7 mm) ),
- the pressure reduction strength when the pressure inside the vessel was reduced was investigated.
- the container according to the reference example in FIG. 9 deformed the shoulder at 41 mmHg, whereas the container according to the present invention did not deform the shoulder up to 55 mmHg, and the decompression strength was significantly higher. It was confirmed to rise.
- the illustrated embodiment of the present invention has been described above by taking a container having a square cross section as an example, the present invention is not limited to this, and may be applied to a container having a circular cross section or a polygonal cross section. Applied. There is no special restriction on the filling capacity of the container, and it is applicable to containers of various sizes, from small containers of about 200 ml or 300 ml to large containers exceeding 1.5 liters, as long as the container has a vacuum absorption panel. It is possible.
