Description

  The present invention relates to a container structure that can be reduced in volume, and more specifically, for example, a container structure that can be easily reduced by reducing the volume by simply crushing a used PET bottle and collecting the container easily. It is about.

  In recent years, PET bottles having a volume of 1.5 liters or 2.0 liters made of resin materials or thin metal materials as containers for drinking water, juices, etc. have been diversified for portable or general household use. ing.

  Used PET bottles with such contents discharged are collected and sent for recycling, and are easily crushed during collection. The current situation is that the volume has not been greatly reduced. Therefore, the volume reduction of used plastic bottles including ordinary households has become an issue.

By the way, some of the commercially available plastic bottles, aluminum cans, steel cans, etc. have been proposed to be easily folded and crushed, but in the case of plastic bottles, the overall rigidity is low. In addition, the shape is not stable, and the content overflows or flows out due to the pressure when holding the plastic bottle, causing a problem in handling (for example, see Patent Document 1).
JP-A-1995-2261 (2nd to 3rd pages, FIG. 1)

  The present invention pays attention to such conventional problems, and maintains the shape during use, and can be easily crushed and reduced in volume after use, and the structure of the container capable of volume reduction that facilitates the collection operation. Is intended to provide.

  In order to achieve the above object, the present invention comprises a portion having a high rigidity and a portion having a low rigidity, with a boundary portion in the vicinity of the symmetrical position in the longitudinal direction of the container body or in the vicinity of the symmetrical position in the radial direction as a boundary. After discharging the contents, the gist of the present invention is that the low rigidity portion is folded into the recess of the high rigidity portion.

  Here, the high rigidity portion of the container body is made of a thick or hard material, and the low rigidity portion is made of a thin or soft material.

  Further, the volume-reducible container structure according to the present invention is configured to be separable at a boundary line in the vicinity of the symmetrical position in the longitudinal direction of the container body or in the vicinity of the symmetrical position in the radial direction, and the contents of the container body The gist of the present invention is that the separated body can be accommodated in the separated body after discharge.

  Thus, when the container body is used, it can be used in a state in which its shape is maintained, and after use, anyone can easily crush and reduce the volume.

  As described above, the present invention is composed of a portion having a high rigidity and a portion having a low rigidity with a boundary portion in the vicinity of the symmetrical position in the longitudinal direction of the container body or in the vicinity of the symmetrical position in the radial direction as a boundary. After discharging, it can be configured so that the low rigidity part is folded in the recess of the high rigidity part, or it can be separated from the boundary line near the longitudinal symmetry position or radial symmetry position of the container body After the contents are discharged from the container body, the other separated body can be accommodated in the separated one separated body, so that the shape is maintained during use, and can be easily crushed and reduced after use. This is advantageous in that it can be easily collected and can be easily collected.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a longitudinal front view of a container made of a resin material (for example, polyethylene) or a thin metal material (aluminum, steel, etc.) showing a first embodiment of the present invention, and FIG. A is a cross-sectional view taken along the arrow A, 1 is a container body, 2 is a cap detachably attached to the mouth portion 3, and is rigid with a boundary portion in the vicinity of the symmetrical position XX in the longitudinal direction of the container body 1 as a boundary. A portion 1A having a high rigidity and a portion 1B having a low rigidity.

  Moreover, as other embodiment, as shown in FIG.3 and FIG.4, the part 1a with high rigidity and the part 1b with low rigidity are bordered on the boundary part of radial position YY vicinity of the said container main body 1 as a boundary. It consists of.

  The highly rigid parts 1A and 1a of the container body 1 are made of a thick or hard material, and the low rigid parts 1B and 1b are made of a thin or soft material. is there. By configuring the container body 1 in this way, after discharging the liquid contents such as water and juice in the container body 1, with the cap 2 removed, as shown in FIGS. By folding the low-rigidity portions 1B and 1b in the recesses of the high-rigidity portions 1A and 1a in the arrow direction F, the volume can be reduced, and as a result, the container can be easily collected. I can do it.

  In this embodiment, the upper half is inverted and folded into the lower half of the container body 1, but conversely, the rigidity of the lower half is lowered and folded into the upper half. Is possible.

  FIG. 5 is a half sectional view of the container body 1 showing the third embodiment of the present invention, and this embodiment can be separated with a boundary line near the symmetrical position XX in the longitudinal direction of the container body 1 as a boundary. Or, as described above, is configured to be separable with a boundary line in the vicinity of the symmetric position Y-Y in the radial direction as a boundary, and after discharging liquid contents such as water and juice in the container body 1, The other separated body 1y can be accommodated in the recess of the separated separated body 1x.

  As another embodiment, as shown in FIG. 6, the mouth 3 (drinking mouth) of the container main body 1 can be provided at a position shifted from the center OO of the container main body 1 to increase the stacking efficiency. As means for facilitating the folding of the container body 1, as shown in FIG. 7, a reinforcing rib 4 is provided on the side opposite to the folding of the container body 1, or as shown in FIG. It is also possible to make the boundary portion 5 thin.

  As described above, after the contents of the container body 1 are discharged, the low rigidity portions 1B and 1b are folded into the recesses of the high rigidity portions 1A and 1a, or the other separation body 1x is separated into the other recess. Since the separator 1y can be accommodated, the shape is held by the highly rigid portions 1A and 1a during use, and after use it can be easily crushed to reduce the volume, facilitating the recovery operation. Is something you can do.

It is a vertical front view of the container main body which shows 1st Embodiment of this invention. It is AA arrow sectional drawing of FIG. It is a vertical front view of the container main body which shows 2nd Embodiment of this invention. It is a BB arrow sectional drawing of FIG.
