Definitions

  • the present invention relates to a synthetic resin liquid container for containing drinking water, juice, milk and other liquids.
  • the problem is to collect empty synthetic resin containers since such containers are bulky and thus occupy a lot of space so that transporting these empty containers is like carrying air. Further, the fact that recycling service companies are generally paid based on the weight of garbage they recovered may contribute to their unwillingness for collecting such containers.
  • an object of the present invention is to provide a synthetic resin container that can be sufficiently resistant to intense oscillation during transport while containig liquid therein and can substantially reduce its volume when it is empty and collected as garbage, thereby enabling transporting much larger number of containers at one time.
  • a synthetic resin liquid container which has a body that can substantially reduce its volume when a vertical and/or twisting stress is applied to the body, and a form-retaining means to be used after compression of the container body for keeping it compressed.
  • the container body comprises a relatively hard and thin side wall with accordion-shaped contour formed on its surface, and sequentially reduced radiuses from both the upper and bottom ends toward the middle of the body, for facilitating operation of substantially reducing the volume of container as described above.
  • the container body comprises a plurality of longitudinal grooves on the surface of its side wall, and a star-shaped cross section, for facilitating operation of substantially reducing the volume of container as described above.
  • the container body comprises a relatively hard and thin side wall, and a number of continuous or non-continuous oblique grooves on the side wall, for facilitating operation of substantially reducing the volume of container as described above.
  • the container body comprises a relatively thin side wall and a number of recesses formed thereon, for facilitating operation of substantially reducing the volume of container as described above.
  • the container body further comprises a belt attached to the opening of the container body, and the belt is in turn connected to a cap, for an aid in keeping the container compressed.
  • the opening of the container body can be embedded into the container body by pressing the opening for keeping the container compressed.
  • the container body also comprises a retainer means which is shorter than the height of the body and has a plurality of legs suspended from the neck portion of the body, with each leg having a claw portion at the tip which engages with the rim of the bottom of the container body for retaining the substantially reduced volume of the container body.
  • the container body also has a retainer member provided on the lower portion of the body, the retainer member having a side wall which is shorter than that of the body, extends in upward direction and has, at the circumferential rim of the side wall thereof, a claw that can be engaged with the top of side wall of the container body.
  • Figure 1 shows a liquid container body (1) made of flexible plastic synthetic resin, and a relatively hard opening (2) with reduced radius provided at the top of the body (1).
  • Figure 1 also shows a cap member (3) covering the opening (2).
  • the container body (1) has a surrounding side wall (4) which is provided with an accordion-shaped contour (5) on its surface between the opening (2) and the bottom of the body (1) across the height of the container body (1).
  • the container body (1) may be filled with liquid such as mineral water using any conventional means, and then sealed with a cap member (3) before it is put on a market.
  • liquid such as mineral water
  • a cap member (3) before it is put on a market.
  • Such a filled container body (1) may be transported almost safely even under oscillation since the accordion like contour (5) of the side wall (4) may provide a buffering function.
  • the container body (1) is emptied and compressed into a direction toward the middle of the body (1).
  • the container may be easily compressed due to flexibility and plasticity of the container body (1) as well as the accordion-shaped contour (5) of the side wall (4).
  • the container body (1) may be placed on the ground and then crushed by foot if the container body cannot be squashed easily by hand.
  • the squashed container body (1) may have thus sufficiently reduced volume.
  • the present inventors put conventional green tea bottles (500ml; height 21cm ⁇ radius 7cm ⁇ ) which are commercially available to the test, by compressing the bottles after making their side walls (4) an accordion-shaped contour (5) as that of the present invention.
  • the results showed that all the container bodies (1) tested were compressed to one-fourth of its original height, which was equal to 5 cm or less. These heights were equal to about two-fold (2L) of those of the relatively hard taper portions (11) of respective container bodies (1), the taper portions (11) being provided just below the opening (2) of the container body (1).
  • the container body (1) is capped again with a cap member (3) at the opening (2) to prevent air introduction into the container body (1) after compression, as shown in Figure 9, so that the container body (1) can keep its compressed form.
  • a capping member (3) may often be discarded or lost after detached from the container body (1) and thus cannot be capped with a cap member (3) after compression of the container body (1).
  • FIG. 10 shows a belt (6) which is made of thin, flexible, plastic resin plate, the plate with openings (7) and (8) close to both ends.
  • the cap (3) has a circumferential side wall and a dovetail groove (9) on the periphery of the side wall.
  • One of the above-described openings (7) provided in the belt (6) is fitted into the dovetail groove (9) while the other (8) is fitted into the proximal end of screw portion (10) provided on the outer surface of the opening (2) of the container body (1).
  • the cap (3) is permanently fixed to the container body (1) so that it may not be lost after once detached.
  • the container body (1) can be kept compressed by recapping with the cap (3) on the opening of the container body (1) after compression.
  • the compressed body (1) has a height equal to about two-fold (2L) of that of the taper portion (5) (L).
  • the container body (1) may be further compressed into smaller size.
  • the taper portion (11) and opening (2) of the container body (1), and optionally a loosely fitted cap (3) are flipped into the container body (1) when the container body (1) is compressed such that these parts may be accommodated in the container body.
  • neither the taper (11) nor the cap may not contribute to the height of the compressed container body (1) so that the body height may be reduced to the same height as those of taper portion (11) and/or cap (L1), thus greatly reducing the bulk of the container.
  • the container body (1) may be compressed by applying a horizontal force (not a vertical force) in order to substantially reduce the volume of the container body (1).
  • the container body (1) may have a plurality of grooves (12) provided on the outer surface thereof with each groove running into the longitudinal direction and being evenly spaced each other.
  • the container body (1) has a star-shaped cross-section (13) as shown in Figure 3.
  • a number of oblique grooves (14) may be formed on the side wall of the container body for horizontal compression as shown in Figures 4 and 5.
  • the emptied container bodies (1) shown in Figures 2 to 5 could be reduced to a size equal to one-third of their original sizes by compressing of the container body (1) them in such a similar manner as laundry is squeezed to remove moisture.
  • the container body (1) may be capped with a cap (3) after compressed to keep it compressed as described above.
  • a lot of compressed containers (1) can be transported by arranging them in a line with each containers (1) being placed upside down shown in Fig.6.
  • the container body (1) may be compressed by applying both vertical and horizontal forces.
  • the container body (1) has a number of recesses such as oblique grooves (15) formed on the surrounding wall (4) thereof as shown in Figure 7, or a continuous spiral groove (16) on the side wall thereof arranged with each parallel line spaced each other in a oblique but relatively horizontal direction as shown in Figure 8.
  • the groove (16) can be discontinuous.
  • an empty container body (1) may be easily compressed merely by applying a vertical pressure since, due to such configuration, not only vertical force but also another force in turning direction are generated and transmitted to the container body (1) such that synthetic force of the two may easily press the container body down.
  • cover members (17) are shown in Figures 12 and 13, which are fitted on the lower portion of container body (1).
  • cover members (17) are generally manufactured from the same material as the container body (1), and may be sold along with the container body (1) containing liquid therein.
  • the cover member (17) is shaped like a bowl with a claw (18) extruding inwardly at the upper open rim.
  • the empty container body (1) is accommodated in the cover member (17) so that the empty container body (1) can keep its compression form.
  • FIG. 13 One example is shown in Figure 13 in which the container body (1) has an accordion-shaped contour (5) on the side wall (4) thereof.
  • the top protrusion of the accordion contour (5) - i.e., the protrusion (19) of the accordion contour (5) just below the taper portion (11) - will engage with the claw (18) of the cover (17). Accordingly, it is important to make the height or depth of the cover member (17) equal to that of the container body (1) in a maximally compressed state.
  • the top protrusion (19) of the container body (1) may have a larger radius than other protrusions in the same accordion contour as shown in Figure 12.
  • the container body (1) may have an accordion contour with each protrusion therein having successively reduced radiuses toward the middle portion (20) across the container length such that the side wall of the container body (1) may be almost evenly and horizontally folded to be accommodated in the next cover member (17) when the container body (1) is pressed into the cover member (17) as shown in Figure 14, thus enabling easy compressing operation of the container.
  • the cover member (17) may be formed as a tube or another form such that it has a discontinuous side wall with a hole or holes (23) from that of the as shown in Figure 16.
  • the cover member (15) may be one which is fit into the lower portion of the container body (1) as described above, or a retainer (24) generally manufactured from the same material as the container body (1) in any form such as those shown in Figures 16 to 18.
  • the retainer (24) may comprise a disk having a hole (25) at its center in which the opening (2) of the container body (1) can fit, and a plurality of leg members (26) under the disk.
  • the leg members (26) can be bumped into engagement with the side wall of the container body (1), and has a claw member (27) at their ends which is adjusted to fit on the container body (1).
  • the retainer (24) may be put on the market together with the container body (1).
  • the claw members (27) of the retainer (24) are engaged with the bottom surface of the container body (1) thereby enabling the container to keep its compression form.
  • the present invention could provide substantially reduced volume of an after-used container body, resulting in saving garbage storage space, thereby enabling a large amount of after-used containers to be transported at one time. This space-saving contributes to expansion of recycling such containers.
  • the container body of the present invention is provided with a retainer means for keeping its compression form so that once compressed the container may not return to its normal shape.
