  • the inventor of the application has suggested a liquid container that can be easily contracted when drained and collected.
  • the liquid container is made of relatively soft synthetic resin, and a body thereof has a bellows peripheral wall with a top tap (Japanese Patent Laid-Open No. 2001-213418, Abstract).
  • an object of the invention is to extremely reduce the capacity of a container body when juice or mineral water in the container body is drunk up and the container body is discarded, and to increase the number of empty container bodies received by a trash can, compared to the related art. This allows transportation of the empty container bodies in large number at the same time.
  • another object of the invention is to extremely reduce collection costs and labor costs for cleaning and collection.
  • a further obj ect of the invention is to extremely increase the number of transported containers per transportation, compared to the related art, when the container is transported from a container manufacturer to a bottler of juice or mineral water.
  • the obj ect of the present invention is, as described above, to extremely reduce the capacity of the container body when the drained container body is discarded or transported.
  • a contracted shape of the container body is kept for a long time, orforalongterm, or until crushing, fusion or other operations for recycling, without any restoring force applied to the container body.
  • the overall shape of the container body according to the invention is selected from columns including elliptical ones, prisms including rectangular ones, and cones and pyramids including truncated ones, and the horizontal cross sectional shape of the container body is selected from circles including ellipses, and squares including rectangles.
  • a further object of the invention is to increase an area on the container body to which a label with an explanation of the content of the container or a trademark printed is affixed, or on which an explanation or a trademark is directly printed, compared to the related art.
  • the container body according to the invention When used as a beverage container, the container body according to the invention has a good appearance to attract much interest of a user, and can be prevented from slipping and falling in use, or the content can be prevented from overflowing.
  • a container capable of keeping a lengthwise contracted state and a contraction method thereof.
  • a feature of the invention is that a container body includes: a top tap; a small width in a height direction at a bottom; and a horizontal bellows formed on the whole or part in a longitudinal direction of the container body, except the top tap, and the width in the height direction.
  • a container body includes: a top tap; a small width in a height direction at a bottom; a flat portion in a middle portion; and a horizontal bellows formed on the whole or part in a longitudinal direction of the container body, except the tap, the width in the height direction, and the flat portion.
  • the bellows of the container When the bellows of the container is pressed longitudinally from both sides thereof toward a center, the bellows is collapsed to overlap, a connection between the top tap and the container body is bent to place the tap in the overlapping bellows and/or the flat portion, and the width in the height direction at the bottom of the container body is placed in the bent and overlapping bellows and/or the flat portion, and this state is kept.
  • the technical scope of the invention includes a further feature that the bellows of the container body has one diameter smaller than the other, with a diameter gradually increasing toward the other end to be a diameter equal to that in a lower portion, and includes a contraction method of a container capable of keeping a lengthwise contracted state, wherein a force is perpendicularly applied to the bellows of the container body, and a force is applied that presses, in one direction, an inner periphery of a piece of fold and/or part of folds that constitute the bellows, causing a force in an opposite direction to be applied to an outer periphery to keep a lengthwise contracted bellows.
  • the technical scope of the invention includes further features that the overall shape of the container body is selected from columns including elliptical ones, prisms including rectangular ones, cones and pyramids including truncated ones, hourglass dram shaped, and barrels; the horizontal cross sectional shape of the container body is selected from circles including ellipses, and squares including rectangles; and a label with an explanation of the content of the container or a trademark printed is affixed to the outer periphery of the container body.
  • the technical scope of the invention includes a container body including: a tap protruding upward from a center of a top; and horizontal bellows formed on inner and outer walls of the whole or part in a length (height) direction of the container body, except the tap, wherein the bellows has an upper diameter smaller than a lower diameter with a diameter gradually increasing toward a lower portion; when a force is perpendicularly applied to the bellows of the container body, the force acts downwards in an inner diameter direction and upwards in an outer diameter direction of upper folds of the bellows, and the force acts upwards in an inner diameter direction and upwards and downwards in an outer diameter direction of lower folds of the bellows to keep a lengthwise (height) contracted bellows of the container body; and when the container body is carried or held after part of, for example, juice is drunk, the container body can be contracted depending on the amount of drunk juice, and the capacity of the container body to be carried or stored can be reduced by the amount.
  • reference numeral 1 denotes a container body, and a bellows 2 is formed on outer and inner peripheries in a height (length) direction of the container body.
  • FIGS. 3 and 6 show a state where, for example, mineral water in the container body 1 is drunk up, and then the container body 1 is collapsed from one side or both sides in the height (length) direction. Specifically, the container body 1 is collapsed and the collapsed state is kept, thus the invention has an excellent configuration and produces excellent effects.
  • reference numeral 3 denotes a tap of the container body 1, with a thread on a periphery thereof, having an about 28 mm diameter and a 23 mm height.
  • a trumpet-shaped connection D having an enlarged lower diameter of about 51 mm and a 5 to 10 mm height is connected to an axis of the tap 3.

  • An outer diameter d of a fourth fold 8, which is the maximum outer diameter of the container body 1, is 35.75 mm, and an inner diameter between the third fold 7 and the fourth fold 8 is 54.5 mm.
  • Each of fifth to twelfth folds has the same diameter as the outer diameter d of the fourth fold 8, and an inner diameter between each of them is the same as that between the third fold 7 and the fourth fold 8.
  • each fold has a shape like an unidentified flying object (UFO) called an Adamski shape, and is horizontally divided into an upper side and a lower side.
  • UFO unidentified flying object
  • the heights of the upper side (h1) and the lower side (h2) of the first fold are 6.5 mm and 5.5 mm
  • those of the second fold are 7 mm and 5 mm
  • those of the third fold are 8.5 mm and 6.5 mm.
  • FIG. 13 shows a sectional shape of the fold in detail. Specifically, as examples of dimensions of the first fold 5 to the third fold 7, an upper surface 20 of a wide double cone shape forms a curve 9 of 20 mmR in this embodiment where the upper surface protrudes outwards, while a lower surface 21 forms a line 11 via a protruding arc 10 of 0.8 mmR, which is significant.
  • the container body 1 in FIG. 1 is divided into a barrel A including a middle portion and a lower portion, and an upper shoulder C, and each of the barrel A and the shoulder C has two, large and small diameters to keep a stable vertical state.
  • the folds having the same inner and outer diameters are formed on the barrel A including the middle portion and the lower portion, the shoulder C is curved to form a gentle protrusion toward the tap 3, and in the shoulder C, an inner diameter of a trough 18 that forms the fold is gradually reduced from the middle portion toward the tap 3, and the inclination of the trough 18 is larger than that in the barrel A.
  • the inner diameter and a slope of a crest 17 and the trough 18 that form the fold can be kept in an extended state by material's own strength and elasticity.
  • a bottom B is recessed with a sharp slope to naturally improve stability.
  • the shoulder C and the barrel A including the upper end lower portion of the container body 1 are compressed and contracted as shown in FIGS. 11 to 16.
  • the folds in the shoulder C are pressed from a state in FIG. 14, an end surface of the trough 18 compresses an end surface of a trough of an adjacent fold.
  • the troughs 18 on both sides are urged toward the top of the crest 17 as shown in FIGS. 15, 16.
  • a component of compression force on the gentle slope of the upper surface 20 of the fold is larger than that on the sharp slope of the lower surface 21, thus the trough 18 on the sharp slope side moves toward the top of the crest 17.
  • the sharp slope passes immediately below the crest 17, and as shown in FIG. 16 is placed inside the gentle slope of the upper surface 20 to reduce the height of the container body 1 to a contracted state, then restoring forces of the inner diameter of the crest 17 and the inner diameter of the trough 18 act, and the lower surface 21, which has been bent by the above described operation, is returned to the extended state to be stable.
  • the contracted state can be kept without a compression force being always applied.
  • the trough 18 with the small diameter receives the compression pressure to further reduce the inner diameter and cause pressure stress.
  • the compression pressure is not applied, the stress is released to return to the extended state.
  • the cap 14 is screwed in a pressurized state to be subjected to atmospheric pressure, the container body 1 keeps the contracted state.
  • no compression stress is caused because of a difference between the inner diameters of the troughs 18, the contracted state is kept.
  • the tap 3 is further pressed toward the bottom B of the container body 1 after the above described state is obtained.
  • the folds tightly contact each other and overlap in the barrel A and the shoulder C of the container body 1, and thus further pushing up the bottom B causes no downward movement.
  • the tap 3 is further pressed downwards, then an end of the trumpet-shaped connection D first presses downwards an inside of the U-shaped groove E. This causes an outer upper end of the groove E to be connected and fastened to the shoulder C.
  • the end of the trumpet-shaped connection D is pressed downwards to move in an enlarging direction with the U shape collapsed and the inside pressed downwards, and finally pressed into the container body 1 together with the tap 3 as shown in FIG. 4.
  • connection D between the tap 3 and the container body 1 is in the trumpet shape, and when collapsed, the connection is reversed and fitted into the container body 1.
  • the height (capacity) of the container body 1 can be sufficiently reduced without forcing the tap 3 into the collapsed container body 1.
  • the fold of the container body 1 has the shape like the wide Adamski type UFO, and is thus horizontally divided into the upper side and the lower side.
  • the heights of the upper side (h1) and the lower side (h2) of the first fold are 6.5 mm and 5.5 mm
  • those of the second fold are 7 mm and 5 mm
  • those of the third fold are 8.5 mm and 6.5 m.
  • the fourth fold 8 to the twelfth fold 12 have the same dimension and the same heights of the upper side (hx) and the lower side (hy).
  • reference numeral 20 denotes the upper surface including an inner surface of the wide Adamski type UFO shape
  • reference numeral 21 denotes the lower surface including the inner surface of the wide Adamski type UFO shape.
  • the upper surface 20 forms the curve 9 of 20 mmR in this embodiment where the upper surface 20 protrudes outwards, while the lower surface 21 forms the line 11 via the protruding arc 10 of 0.8 mmR, which is significant.
  • the trough 18 with the small inner diameter receives the compression pressure to cause pressure stress.
  • the compression pressure is not applied, the stress is released to return to the extended state.
  • the cap 14 is screwed in the pressurized state to be subjected to atmospheric pressure, the container body 1 keeps the contracted state.
  • no compression stress is caused by the difference between the inner diameters of the troughs 18, the contracted state is kept.
  • the diameter of the fold in the shoulder C of the container body 1 increases toward the lower portion as described above, and thus the collapsed folds overlap in a slope shape where the outer periphery is higher than the inner periphery.
  • a pressing down force acts on the outer periphery of each fold as shown in FIG. 11.
  • the folds of the barrel A including the middle portion and the lower portion overlap in a slope shape opposite in direction to that in the shoulder C, where the outer periphery is lower than the inner periphery.
  • the dome shape 4 and the curve 9 that form the upper slope of the fold in the shoulder C and the lower slope of the fold in the barrel A are balanced to keep the collapsed state without placing the cap 14 back on the container body 1.
  • the tap 3 is pressed and embedded in the container body 1, and at the same time, the bottom B and its surroundings of the container body 1 is embedded in the container body 1 by an effect corresponding to reversing the shoulder C of the container body 1, thus the height (capacity) of the container body 1 can be reduced by a factor of about 5, compared to the empty container body 1 to be discarded without being collapsed.
  • beverage is generally contained in a 500 ml container, and the beverage is rarely drunk up at a time.
  • a container has to be carried that contains remaining beverage and an empty portion with the capacity unchanged.
  • the container according to the invention can be carried with an empty portion after drained being compressed, and be accommodated in a handbag.
  • Relatively weak children or women can easily collapse the container body 1 by stepping thereon as shown in FIG. 7, besides pressing by hands.
  • PET bottles often used as beverage containers include a flat portion for a label J that indicates a trademark, an explanation of the content, or a source on a middle portion of the container body 1, which is shown in FIGS. 8 to 10.
  • the empty container body 1 after the content is drunk up is collapsed similarly as described above, and detailed descriptions thereof will be omitted.
  • the portion for a label J is provided on the middle portion of the container body 1 and has an inner diameter substantially equal to the outer diameter of the bellows 2 of the container body 1, and when the container body 1 is collapsed from upward and downward, the tap 3, and the bottom B and its surroundings are pressed into the portion for a label J to keep a collapsed state with good appearance and without loosing its shape.
  • the number of container body 1 received by the trash can extremely increase, and the discarded container body 1 has good appearance.
  • the container body 1 is cylindrical or in the shape similar thereto.
  • a container body 1 in an hourglass dram shape in a vertical direction is easy to grip, and a container body 1 in a truncated cone shape K or a truncated pyramid shape is stable as shown in FIG. 20, and any appropriate shape can be selected.
  • the portion for a label J may be provided on the lower portion of the container body 1 as shown in FIG. 21, on the upper portion as shown in FIG. 22, or on both portions as in FIG. 23.
  • the bellows 2 formed on the container body 1 is in the shape of vertically continuous, horizontal annular folds.
  • folds in a continuous spiral shape can be more easily collapsed by a twisting force applied in addition to the vertical pressing force toward the upper portion or the middle portion of the container body 1.
  • the spiral may be formed of several streaks rather than a single streak.
  • the main advantage of the invention described above is to extremely reduce the capacity of the container body when the container is discarded, and to increase the number of container bodies received by the trash can or the like.
  • the contracted container bodies can be transported in large number at the same time to extremely reduce collection costs and labor costs for cleaning and collection.
  • the container body according to the invention has a good appearance to attract much interest of a user, and the bellows of the container body serves as a friction stop to prevent the container body from slipping and falling in use, or prevent the content from overflowing.
  • the container body collapsed according to the invention has a good design, and thus can be used as an outer container as it is.
