Definitions

  • This invention generally relates to a contractible bellows container. More particularly, this invention relates to a contraction-controlled bellows container.
  • a conventional contractible bellows container chiefly comprises a generally tubular bottlelike container portion and bellows which protrude at a right angle from the container portion.
  • a conventional contractible bellows container is generally used to contain and press out a viscous material.
  • Each conventional bellows ridge is formed as a ring body, provided around the container body portion, consisting of two plane rings of the same size. The two plane rings meet at their outer rims with an angle and provide a circular outer hinge (hereinafter referred to as "outer hinge”).
  • the inner circular hinges (hereinafter referred to as “inner hinges”) of the plane rings are apart.
  • a hard plastic bottle like a PET (polyethylene terephthalate) bottle may be provided with conventional bellows, but it would not be contracted easily because of the considerable repulsive forces from all its bellows.
  • Japanese Utility Model Laid-Open Publication No. 55-158032 discloses a contractible plastic bellows container having bellows each ridge formed of a plane upper wall and a plane lower wall.
  • the upper wall and lower wall of each bellows ridge are differently angled or mixed in an attempt to reduce the repulsive force from the ridge.
  • the problem of the repulsion is not corrected completely due to the "plane" wall configuration of the bellows.
  • the problem of shape restoration of the bellows is not addressed, either.
  • those bellows cannot be fully closed as the upper walls and lower walls are differently sized, causing unintended distortion in the bellows walls, as a person skilled in the art will realize.
  • Japanese Patent Publication No. 2-19253 discloses a contractible plastic bellows container having "open rings" provided at the inner hinges of the bellows in an attempt to ease the contraction of the bellows and prevent degradation of the material at these hinges in repeated uses.
  • Those open rings are provided astride the upper walls and lower walls equally.
  • those open rings are naturally made "thick" by blow molding which is the conventional and most widely utilized plastic container manufacturing method. These thick rings do not ease contraction of the bellows very well.
  • the problem of restoration of shape is not dealt with in this bellows container, either. Those bellows will not fully close as their upper walls and lower walls are differently sized, causing unintended distortion in the bellows walls.
  • Japanese Patent Publication No. 64-58660 discloses a inflatable plastic bellows container which utilizes a number of hemispheric (in vertical section) bellows unlike the foregoing two bellows containers which utilize plane bellows walls.
  • the bellows ridges of this container are originally contracted and layered to be pulled upward in use to open.
  • bellows are provided with a small protruding or depressed circumferential wedge at each outer hinge to smooth the opening of the bellows.
  • Such wedges would eliminate the aforementioned unfavorable deformation of the bellows walls to an extent.
  • these protrusions or concavities are equally provided astride the upper walls and lower walls of the bellows, and no distinction of function between these walls is intended.
  • Bellows having such a hemispheric configuration would intrinsically warp to one side when contracted. (This is one of the features intended in the present invention.) The direction of warping is not controlled, and therefore the randomly (upwardly or downwardly) warping bellows would likely hinder the layering of the bellows ridges.
  • each bellows ridge is vertically wide apart when the ridge is open, it would take a considerable "time" for each bellows ridge to show the termination of the restoration of shape when used conventionally.
  • the bellows would retain a restorative function during most of use.
  • That container additionally utilises open rings provided at the inner hinges (not on the upper walls or inner walls of the bellows) to ease the opening of the bellows.
  • the open rings are intrinsically made thick and would not function as desired. Rather, these open rings would prevent full contraction of the bellows ridges.
  • plastic containers including contractible plastic bellows containers are manufactured by blow molding, which is suitable for mass production of plastic containers.
  • blow molding is suitable for mass production of plastic containers.
  • the outer hinge portions are made the thinnest and the inner hinge portions are made the thickest (excluding the top and bottom portions of the container). It is impractical not to take such so intrinsic feature of blow molding into consideration in designing a plastic bellows container.
  • there also exist a number of restrictions intrinsic to blow molding It is also impractical not to take these intrinsic restrictions into consideration.
  • Bellows containers according to the present invention are designed so that they can be advantageously manufactured by blow molding, however, contractible bellows containers according to the present invention may be manufactured by other molding methods presently known in the art. Plastic materials for manufacturing the containers of the present invention may be freely selected from those known in the art as well.
  • the bellows of the present invention are generally and basically convex, their upper walls and lower walls being roundly protruded in their overall configurations.
  • the bellows ridge gradually loses restoration of shape when a wall is gradually turned from its convex configuration to concave configuration, eventually to a substantially symmetrical configuration. Once that wall assumes the shape of concavity, the wall is next provided with a motion or energy working toward the other wall and it finally contacts the other wall.
  • the contracted bellows ridge warps toward that concave wall.
  • the bellows ridges or the present invention can assume other configurations and still enjoy the features intended by the present invention, which will be explained later in detail.
  • the wall of a bellows ridge may be substantially "plane.”
  • Bellows containers of the present invention can have various configurations in horizontal section, not only a circular configuration but also oval or square configurations to name a few. Accordingly, the term "circular configuration” as used hereinafter should be construed as including an oval configuration and other configurations which are continuous circumferential "ring" configurations.
  • the bellows or a bellows container according to the present invention at least selectively have a circular or circumferential indentation or indentations in their upper walls and/or lower walls.
  • a circular indentation is provided generally adjacent the outer hinge or one of the inner hinges of a bellows ridge.
  • the term “circular indentation” or “circumferential indentation” is generally referred to as “indentation” for the convenience of description.
  • One bellows ridge may have two or more of such indentations in its lower wall or upper well, or each wall may have one indentation or more.
  • an indentation is subject to the overall design of the indentation, including its "size” which may be conveniently represented by the vertical sectional depression area. However, that function is also subject to the shape of the indentation including the depth and length as well as local angles of the indentation Generally, a large size indentation will provide a better utilization of pressure energy than a small size indentation. Here, “better utilization” means that a bellows ridge having a large indentation can be further depressed preferentially to and more easily thin another bellows ridge having a small indentation.
  • the order of contraction of bellows ridge can thus be controlled by providing the bellows ridges with different size indentations, respectively, which substantially reduces the pressing energy required since the pressing energy can be substantially concentrated on one bellows ridge, or utilized ridge by ridge.
  • FIG. 1 is a vertical sectional view of a bellows container having bellows according to an embodiment of the present invention, taken along its longitudinal axis, and a partially enlarged view showing a bellows ridge portion in vertical section.

  • Fig. 8(a) to Fig. 8(c) show the contraction process of the ridge portion.
  • FIG. 9 is a vertical sectional view of a bellows ridge portion according to a special embodiment of the present invention.
  • Fig. 1 shows a bellows container 1 according to an embodiment of the present invention, each bellows ridge portion 2 (hereinafter generally referred to on “bellows ridge” or just “ridge” for the convenience of description) having a convex upper wall 21 and a substantially convex lower wall 22.
  • the degrees of the convexities will be determined depending upon factors much as use, material, size, etc., of the container 1.
  • pressure suction
  • Each bellows ridge 2 in this embodiment is provided with a circular indentation 3 on its lower wall 22 adjacent the outer hinge 23.
  • the highest portion of the indentation 3 will not generally go above the imaginative horizontal plane including the outer hinge 23.
  • the overall configuration of the indentation 3 including vertical depth (d) and horizontal width (w) will be designed subject to the shape, size, material, etc., of the bellows ridge 2 as well as the contractional feature desired of the bellows ridge 2.
  • Such an indentation way be configured with a combination of (a) curves, (b) curves and lines, or (c) a combination of lines.
  • a) curves curves and lines
  • a combination of lines a combination of lines.
  • the pressure When the bellows container 1 is pressed vertically, the pressure first acts upon the inner hinges 24 of the bellows ridges 2 in opposite directions, respectively. Then the pressures working on the inner hinges 24 are partially converted into the "rotary moments" to work on the upper walls 21 and lower walls 22 of the bellows ridges 2, the outer hinges 23 working as circular rotary fulcrums, respectively.
  • the indentations 3 provided in the lower walls 22 absorb and utilize the rotary moments prior to the corresponding portions of the upper walls 21 and are depressed further into the bellows ridges 2, bringing together the other portions of the lower walls 22.
  • the upper walls 21 will substantially retain their original convex configuration (which provides considerable resistance against deformation, as will be understood by a person skilled in the art) and will assist further depression of the indentations 3 without utilizing the rotary moments acting upon the upper walls 21 for themselves.
  • the pressure applied on the container 1 is effectively absorbed and utilized at the indentations 3 and the bellows ridges 2 are easily deformed from the lower walls 22, as shown in Fig. 1(a).
  • bellows ridges 2 having such indentations 3 will start closing with less pressure on the container 1 than bellows ridges having no such indentations.
  • Fig. 2 shows a bellows ridge 2 according to another embodiment of the present invention.
  • a plurality of such bellows ridges 2 are to be incorporated in a bellows container. This applies to the other embodiments showing only a single bellows ridge.
  • This bellows ridge 2 has an indentation 3 in the lower wall 22 adjacent its inner hinge 24. When a pressure is applied on the container (not shown) vertically, the inner hinges 24 of the bellows ridge 2 receive the pressure (the upper wall 21 receiving a downward pressure and the lower wall 22 receiving an upward pressure).
  • the downward pressure on the upper inner hinge 24 is converted into a rotary moment working on the upper wall 21, and the upward pressure on the lower inner hinge 24 is converted into a rotary moment working on the lower wall 22, both hinging on the outer hinge 23.
  • These rotary moments are first partially consumed to deform the outermost portions of the bellow ridge 2 substantially equally, as shown in Fig. 2(a). Then the rotary moment of the lower wall 22 is partially utilized at the indentation 3 prior to the corresponding portion of the upper wall 21, and the lower wall 22 starts entering the bellows ridge 2 as shown in Fig. 2(b).
  • Fig. 2(c) shows the state of the bellows ridge 2 which is fully contracted.
  • Fig. 3 shows a bellows ridge 2 according to another embodiment of the present invention, having two indentations 3 and 3' in the lower wall 22, one 3 adjacent the outer hinge 23, and the other 3' adjacent its inner hinge 24. Both the indentations 3 and 3' will respectively function as explained earlier.
  • the lower wall 22 will be depressed prior to the upper wall 21 more easily than a case of only a single indentation due to the dual function of two indentations.
  • indentations 3 (and 3') described in the foregoing three embodiments may be provided on their respective upper walls 21 instead (not shown here), in which cases the functions of the indentations 3 take place on the upper walls 21, and the bellows ridges 2 will warp upwards when closed.
  • Fig. 4 shows an arrangement of bellows ridges 2 according to an embodiment of the present invention.
  • Indentations 3 here are provided on the upper walls 21 adjacent their outer hinges 23.
  • the upper walls 21 will be depressed toward the lower walls 22 respectively.
  • the contracted bellows 2 will warp upwards and will be layered neatly as shown in Fig. 5.
  • Fig. 6 shows another arrangement of bellows ridges 2 according to another embodiment of the present invention, which will be utilized to greater advantage in a hard plastic container such as a PET bottle (not shown).
  • the "sizes" of indentations 3 respectively provided in the lower walls 22 of the bellows 2 adjacent their outer hinges 23 are different.
  • the uppermost indentation 3 is the largest in size and the lowermost indentation 3 is the smallest in size.
  • size here is defined as described earlier as meaning that a larger size will provide the aforementioned function of an indentation better than a smaller size.
  • the indentation 3 and lower wall 22 of the uppermost bellow, ridge 2 will be first depressed by utilizing the applied pressure prior to the others, and the indentation 3 and lower wall 22 of the lowermost bellows ridge 2 will be depressed last. All bellows ridges 2 will warp downwards and will be layered neatly (not shown). Thus, it is possible to selectively control the order of depression timing of bellows ridges by adjusting the "size" of each indentation. When provided with this type of indentation arrangement, a hard plastic bottle having such bellows will only require substantially less pressure to contract as the pressure energy is utilized substantially ridge by ridge.
  • Fig. 7 shows another arrangement of bellows ridges 2 according to another embodiment of the present invention, having indentations 3 on their lower walls 22 adjacent the respective inner hinges 24.
  • the lowermost indentation 3 has the largest size and the uppermost indentation has the smallest size.
  • the lower wall 22 of the lowermost bellows ridge 2 will be depressed first and the lower wall 22 of the uppermost bellows ridge 2 will be depressed last. All bellows ridges 2 will warp downwards and will be layered neatly (not shown).
  • the indentations 3 of different sizes of the two embodiments above may be respectively provided on the upper walls 21 instead (not shown), in which cases, the functions of the indentations 3 will take place on the upper walls 21, and the bellows ridges 2 will warp upward to be layered neatly.
  • a hard plastic bellows bottle having such size controlled indentations on its bellows will be very easily depressed.
  • the freshness of the drink can be kept a long time since the bottle can be depressed ridge by ridge as the content decreases, and each contracted bellows ridge will be held contracted.
  • the loss of shape restoration of a single hollows ridge will take place quickly. Therefore, only little air will be sucked into the bottle.
  • Fig. 8 shows a bellows ridge 2 according to an applied embodiment of the present invention.
  • the upper wall 21 has an indentation 3' adjacent its inner hinge 24, and the lower wall 22 has an indentation 3 adjacent the outer hinge 23.
  • the bellows ridge 2 will generally be depressed from the lower wall 22 since the indentation 3 provided nearer the outer hinge 23 will utilize the aforedescribed rotary moment prior to the corresponding portion of the upper wall 21 as well as prior to the indentation 3' provided adjacent the inner hinge 24.
  • the indentation 3' in this case will work to assist and promote the whole depression of the bellows ridge 2. However, if the "size" of the indentation 3' is substantially larger than the indentation 3, then the upper wall 21 may be depressed instead of the lower wall 22 (not shown).
  • Fig. 9 shows a bellows ridge 2 according to a special embodiment of the present invention.
  • a sufficient indentation 3 is provided in the lower wall 22 adjacent the outer hinge 23.
  • the upper wall 21 is substantially plane. As will be understood by a person skilled in the art, the upper wall 21 is made thicker conventionally than when it is convex or concave, thus the upper wall 21 is considerably more rigid than the lower wall 22.

  • the upper wall 21 will eventually and slightly warp downwards.
  • the ridge configuration may be provided upside down, in which case the upper wall 21 will enter the bellows ridge 2 (not shown).
  • the lower wall 22 can be substantially plane so well except the portion of the indentation 3 (not shown), in which case, the lower wall 22 will still be depressed into the ridge 2 due to the function of the indentation 3.
