Description
- 1. Field of the Invention
- The present invention relates to a plastic beverage container or bottle for holding liquids such as soft drinks and the like, and more particularly to a plastic beverage container or bottle that is easy to hold.
- 2. Background of the Invention
- Generally, a plastic bottle, such as a PET bottle, is widely known and marketed as a beverage container. Some large capacity bottles of approximately one to two liters have been improved with respect to ease-of-holding when pouring a drink. In the bottles described in Japanese Published Patent Application 2005-247393 and Japanese Patent 3059975, for example, a finger insertion indentation into which a consumer can insert and engage his or her finger is formed on the barrel portion of the bottle. On these bottles, a single finger insertion indentation is formed at the center of both the front wall and the rear wall of the barrel portion such that the consumer can hold the barrel portion using either the left or right hand alone. The finger insertion indentations are configured by sharing a portion of a ring-shaped concave rib, which assures the strength of the barrel portion.
- Depending on bottle size or the cross-sectional shape, however, a consumer with small hands may not be able to reach the front or rear finger insertion indentation with his or her fingers, or even if the consumer can reach the indentation, he or she may be straining to hold the bottle, making it difficult to pour the drink in the bottle. For example, when the cross sectional shape is a rectangle and a finger insertion indentation is formed on a long-sided wall, the distance from the short-sided wall to the finger insertion indentation increases, making it difficult to hold the bottle with one hand using the finger insertion indentation. Forming the finger insertion indentation to be large enough to span the entire width of the barrel portion may address this problem. However, such a configuration reduces the strength of the barrel portion (particularly, longitudinal strength) as well as the strength of the finger insertion indentation.
- It is accordingly an object of the invention to provide a plastic bottle that improves the ease of one-handed holding of the barrel portion while assuring the strength of the barrel portion and an indentation for insertion of a finger.
- In accordance with the invention, a beverage container includes a barrel portion having a substantially square cross-sectional shape defined by a plurality of walls including at least a front wall, a rear wall, a left side wall, and a right side wall. The container also includes a pair of indentations formed in at least one of the front and rear walls for insertion of, and engagement with, a finger, and a column portion separating the pair of indentations into left and right portions. Each of the pair of indentations has a bottom wall, a first side wall extending from the bottom wall to the column portion, and a second side wall extending from the bottom wall and facing the first side wall, the second side wall having a peak portion extending along a corner portion of the substantially square cross-sectional shape.
- Additional objects and advantages of the invention will be set forth in the description which follows. Still other objects and advantages will be obvious from the description or may be learned by practice of the invention. The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

FIG. 14 is a cross-sectional view at line XIV-XIV inFIG. 11 . - In one embodiment, a beverage container or bottle includes a barrel portion having a substantially square cross-sectional shape defined by a plurality of walls including at least a front wall, a rear wall, a left side wall, and a right side wall. The container also includes a pair of indentations formed in at least one of the front and rear walls for insertion of, and engagement with, a finger, and a column portion separating the pair of indentations into left and right portions. Each of the pair of indentations has a bottom wall, a first side wall extending from the bottom wall to the column portion, and a second side wall extending from the bottom wall and facing the first side wall, the second side wall having a peak portion extending along a corner portion of the substantially square cross-sectional shape.
- The bottle according to this embodiment permits even persons with small hands to easily insert a finger into one of the pair of indentations. Therefore, one-handed ease of holding of the barrel portion can be improved without forcing users to strain at holding the bottle. At the same time, because there is a column portion between the pair of indentations, longitudinal strength of the barrel portion can also be assured. Also, a peak portion of the second side wall is formed using the comparatively high strength corner portion of the substantially square cross-sectional parts. This enables effective improvement of the strength of the second side wall on which a fingertip is engaged when the bottle is tilted.
- The sloping angle from the bottom wall is preferably more gradual on the first side wall than on the second side wall. By so doing, the relatively gradual first side wall enables an improvement in the ease of fingertip insertion into the indentation. It also permits a relatively large rib effect to be achieved using the relatively steep second side wall, thereby increasing the strength thereof.
- Preferably the first side wall may have a portion that is sloped with respect to the up and down direction such that the tip of a finger inserted in the indentation is inclined to the center axis side. This configuration may be useful, for example, in cases where the pour spout for a liquid is on the center axis of the bottle. Specifically, fitting of the finger into the indentation is stabilized when the bottle is tilted in order to pour a liquid. This makes it easier to pour a liquid.
- In one embodiment, the indentation preferably has a third side wall connecting the top side portion of the first side wall and the second side wall, and the third side wall is preferably curved upwardly. In such configuration, fingertips more easily conform to the third side wall compared to the case in which the third side wall is flat. Concentration of stress when a load is applied to the third wall can also be avoided, as can flexion of the bottle.
- The indentation is preferably formed to face the front and rear walls. By so doing, fingertips can be engaged on the indentations at the front and rear, significantly improving ease of bottle holding.
- Also, the plurality of walls may preferably have corner walls connecting between the front wall, rear wall, left wall, and right wall, respectively. The peak portion formed on the front wall also preferably extends along the corner portion connecting the front wall to the corner wall, and the peak portion formed on the rear wall preferably extends along the corner portion connecting the rear wall to the corner wall.
- The indentation is preferably positioned in the vicinity of the center of gravity when the plastic bottle is fully filled with a fluid. By so doing, ease of holding can be improved by such means as enabling fingertips to be engaged on the indentation close to the center of gravity. Stable handling is also enabled; when a liquid is poured into a glass, for example, stable manipulation can be achieved by rotating [the bottle] in a trajectory centered on the holding hand when tilting the bottle horizontally.
- In one embodiment, the cross-sectional shape of the bottle is more preferably a substantially rectangular cross-sectional shape having the length of the front and rear walls longer than that of the left and right walls. The barrel portion preferably includes an upper barrel portion, a lower barrel portion, and a center barrel portion between the upper barrel portion and the lower barrel portion. The center barrel portion preferably contains the center of gravity and has indentations formed within it. It is also preferable for the center barrel portion to have constricted portions on the left and right side walls which curve inward more than the upper barrel portion and the lower barrel portion when viewed from the front side and the rear side. By using the constricted portions, this configuration allows the distance from the left and right walls to the indentations to be shortened. This then enables easier gripping of the center barrel portion and allows people to hold the bottle at a position closer to the center of gravity. Also it enables people to recognize which part of the bottle to hold easier.
- The constricted portion is more preferably formed to span over the entire area of the center barrel portion. So doing allows the constricted portions to be formed over a wide span, thereby improving not only ease of holding but also bottle design characteristics.
- The bottle preferably has a shoulder portion connected to the top end of the barrel portion, a bottom portion connected to the bottom end of the barrel portion, and a reinforcing concave rib formed on at least one of the shoulder portion, the barrel portion, and the bottom portion. The sectional shape of the bottom surface of the concave rib is preferably dissimilar to the substantially rectangular sectional shape in portions not having a concave rib. By so doing, the reinforcing effect on transverse strength from the concave rib can be increased, and deformation of the shoulder portion, barrel portion, or bottom portion can be suppressed.
- Referring to the figures, exemplary embodiments of the present invention are described.
- As shown in
FIGS. 1 and 2 , the plastic bottle 1 is formed by stretch molding methods such as biaxial stretch-blow molding or the like using a thermoplastic resin such as polyethylene, polypropylene, polyethylene terephthalate or the like as a primary material. Here, the bottle 1 is formed into a rectangular bottle with a height of approximately 300 mm and a capacity of approximately 2000 ml. The capacity of the bottle is freely selectable, but the present embodiment may be well suited for large capacity bottles for 700 ml or greater. - After molding, the bottle 1 is washed and sterilized, then filled with drink. Non-carbonated drinks such as water, green tea, oolong tea, or fruit juices and the like are examples of such drinks. In general, internal bottle pressure is negative for non-carbonated drinks, which weakens bottle strength so that concave ribs are formed on the bottle to assure that strength. The bottle 1 of the present embodiment has
concave ribs - Various terms used in this specification are defined as follows.
- The terms “up,” “down,” “left,” “right,” “front” and “rear” are used in reference to directions or parts of the bottle shown in
FIG. 1 . The up-down or vertical direction means the center axis Y-Y direction of the bottle 1. The bottle 1 left-right length and front-rear length respectively correspond to the width and depth of the bottle 1. Height means the length along the center axis Y-Y. Sectional or cross-sectional shape means the sectional shape of a plane (sectional surface) of the bottle 1 perpendicular to the center axis Y-Y. Circumferential direction means the direction of circulation along the profile of the sectional shape. - In order starting from the top of the center axis Y-Y, the bottle 1 has a
spout portion 2, ashoulder portion 3, abarrel portion 4, and abottom portion 5. These portions 2-5 are integrally formed, constituting bottle walls capable of holding drinks within. The center of gravity G for a bottle 1 filled with a drink is on the center axis Y-Y. Thespout portion 2 opens at its top end and functions as a pour spout for drinks. The opening at thespout portion 2 opens and closes using a cap (not shown in figures). Theshoulder portion 3 connects to the bottom end of theopening portion 2. The sectional shape of theshoulder portion 3 gradually expands downwardly, and the bottom end of theshoulder portion 3 is connected to the top end of thebarrel portion 4. The boundary between theshoulder portion 3 and thebarrel portion 4 is demarcated by theconcave rib 11. Thebottom portion 5 comprises abottom wall 21 and aperimeter wall 22. Theperimeter wall 22 is a part that rises from the perimeter of thebottom wall 21 in a widening fashion, and is formed in a cylindrical shape. Theconcave rib 12 is continuous at the top end of theperimeter wall 22, and a boundary is marked by theconcave rib 12 between thebottom portion 5 and thebarrel portion 4. - For ease of explanation, the boundaries of the
shoulder portion 3, thebarrel portion 4, and thebottom portion 5 using theconcave ribs barrel portion 4 may also be positioned on the upper side of theconcave rib 11, or the bottom end of thebarrel portion 4 positioned on the lower side of theconcave rib 12, etc. - The
barrel portion 4 extends in a vertical direction between theshoulder portion 3 and thebottom portion 5. Thebarrel portion 4 is formed to be left-right and front-rear symmetrical around the center axis Y-Y. Thebarrel portion 4 is constituted to have basically a substantially rectangular shape having a plurality of walls 41-45. Specifically, as shown inFIG. 3 the sectional shape includes afront wall 41, arear wall 42, aleft side wall 43, aright side wall 44, and fourcorner walls 45 respectively connecting between these walls. The length of the front andrear walls 41 and 42 (i.e. the width) is longer than the length of the left andright side walls 43 and 44 (i.e. the depth). - As shown in
FIG. 3 , thecorner wall 45 may be a curved surface that curves outwardly and is connected to the other walls 41-44 via twocorner portions corner portions corner portions corner wall 45 is that thecorner portion 46 a is connected to the left andright side walls corner portion 46 b is connected to the front andrear walls barrel portion 4 has a total of eightcorner portions corner walls 45 is shorter than that of the other walls 41-44, therefore the space between each of the walls 41-44 may also be seen to be rounded, with the result that when what is precisely described as the octagonal cross-section is viewed as a whole, it can be categorized as “substantially rectangular.” - As shown in
FIGS. 1 and 2 , thebarrel portion 4 is divided into three areas in the vertical direction, having anupper barrel portion 51, acenter barrel portion 52, and alower barrel portion 53. The basis for this division is the presence or absence of a center of gravity G,indentations column portion 58. The location where these are present is deemed thecenter barrel portion 52. The height of thecenter barrel portion 52 is slightly higher than the height of theupper barrel portion 51 and thelower barrel portion 53, but it can be of a similar level. Theupper barrel portion 51,center barrel portion 52, andlower barrel portion 53 are formed with the same cross-sectional shape. However, the cross-sectional shapes of theupper barrel portion 51, thecenter barrel portion 52, and thelower barrel portion 53 may differ from one another so long as they are basically substantially rectangular. For example, theupper barrel portion 51,center barrel portion 52, andlower barrel portion 53 can be formed to have similar cross-sectional shapes, or a constriction could be formed in any of them. - In addition to the above-described
concave ribs barrel portion 4 may haveconcave ribs indentations annular channel 15 that is continuous circumferentially between theconcave rib 12 and theconcave rib 14. Here, the area between theconcave rib 11 and theconcave rib 13 is theupper barrel portion 51, the area between theconcave rib 13 and theconcave rib 14 is thecenter barrel portion 52, and the area between theconcave rib 14 and theconcave rib 12 is thelower barrel portion 53. - The
upper barrel portion 51 may have depressurizationabsorption panel portions 71 on the front andrear walls upper barrel portion 51 has threechannels 72 up and down on the left andright side walls center barrel portion 52 has fourchannels 73 up and down on the left andright side walls channels upper barrel portion 51 and thecenter barrel portion 52. Thechannels right side walls corner walls channels corner portions 46 a and thecorner portions 46 b. - The
indentations indentations indentations rear walls - Specifically, as shown in
FIG. 4 , anindentation 56 and anindentation 57 are formed at the left and right of thefront wall 41, separated by thecolumn portion 58. Similarly, anindentation 56 and anindentation 57 are also formed on therear wall 42, separated by thecolumn portion 58. The front andrear indentations rear indentations column portion 58 is in a center position in the left-right direction, with an upper portion which is long and narrow and a lower portion which is triangular in plan view (seeFIG. 1 ). The longitudinal strength of thecenter barrel portion 52 is increased by thecolumn portion 58. - The
indentations indentations bottom wall 91 and aperimeter wall 92 which rises from the perimeter of thebottom wall 91. Thebottom wall 91 comprises a flat surface parallel to the center axis Y-Y. Theperimeter wall 92 comprises aside wall 94 on thecolumn portion 58 side, aside wall 95 facing theside wall 94, anupper side wall 96, and alower side wall 97. As noted above, thebarrel portion 4 is left-right and front-rear symmetrical, therefore the explanation below focuses in some cases on one of theindentations - The
side wall 94 has a more gradual slope (angle of inclination) from thebottom wall 91 than does theside wall 95. A fingertip can therefore be more easily inserted using the comparativelygradual side wall 94, and a rib effect can be achieved using the comparativelysteep side wall 95. The upper part of theside wall 94 extends in parallel to the center axis Y-Y, and the lower portion [thereof] is inclined downward toward theside wall 95. By so doing, aligning an inserted index finger with theside wall 95 results in the tip of the index finger being inclined toward the center axis Y-Y side. Therefore fitting of the index finger in theindentation 56 is stabilized when the bottle 1 is tilted in order to pour a drink, making the drink easy to pour. - The
side wall 95 extends parallel to the center axis Y-Y. Theside wall 95 has apeak portion 98, which is furthest from thebottom wall 91. Thepeak portion 98 extends in parallel to the center axis Y-Y along thecorner portion 46 b. A finger is frequently engaged on theside wall 95 when the bottle 1 is tilted to pour a drink. Therefore strength is required of theside wall 95. On this point, thepeak portion 98 is positioned on thecorner portion 46 b, which has a higher strength than the side portions in a substantially square cross-sectional shape; therefore the strength of theside wall 95 is increased. - A
side wall 96 connects the upper portion between theside wall 94 and theside wall 95. Theside wall 96 is curved so as to swell upward. This configuration makes it easy for a fingertip to fit into the curved surface of theside wall 96 when a fingertip contacts theside wall 96. At the same time, aside wall 97 connects the lower portion between theside wall 94 and theside wall 95. Theside wall 97 curves downwardly with a curvature radius which is smaller than that of theside wall 96. Theside wall 97 is preferably formed with a size and curvature radius such that the first joint on the index finger fits therein. This results in the index finger being fixed on theside wall 97, thereby stabilizing the inclined position of the bottle 1 when pouring. - As explained above, the bottle 1 of the present embodiment allows a person to easily accommodate and engage a finger in at least one of a pair of
indentations rear indentations - In particular, a person can easily engage his or her finger on the
indentation indentations column portion 58 between the pair ofindentations barrel portion 4 to be assured. A favorable improvement in strength can also be achieved as described above with respect to theside wall 95, on which fingers are frequently engaged. - Referring to
FIGS. 5 through 10 , a second embodiment of the bottle is described. The differences with respect to the first embodiment are the addition of constrictedportions - As shown in
FIGS. 6 and 7 , in addition to a center of gravity G,indentations column portion 58, thecenter barrel portion 52 includes constrictedportions portions center barrel portion 52. The constrictedportions indentations indentations center barrel portion 52 is increased by theupper rib 76 on theindentations concave rib 76 is non-continuous in the circumferential direction. Theconcave rib 75 below theindentations lower barrel portion 53. - The
upper barrel portion 51 and thelower barrel portion 53 are formed to have the same substantially rectangular cross-sectional shape (seeFIGS. 5 and 8 ). At the same time, the cross-sectional shape of thecenter barrel portion 52 is smaller than the cross-sectional shape of theupper barrel portion 51 and thelower barrel portion 53 due to the effect of the constrictedportions upper barrel portion 51, thecenter barrel portion 52, and thelower barrel portion 53 are, as noted above, basically rectangular (precisely speaking, octagonal). - As shown in
FIG. 9(A) , theconstricted portion 54 is formed on theleft side wall 43 and theconstricted portion 55 is formed on theright side wall 44. Theconstricted portion 54 passes theleft side wall 43 to thecorner walls left side wall 43. Similarly, theconstricted portion 55 passes theright side wall 44 to thecorner walls left side wall 44. The constrictedportions upper barrel portion 51 and thelower barrel portion 53 when thebarrel portion 4 is viewed from the front and back sides (“front view” below). Put another way, in the front view the constrictedportions - The constricted
portions channel 81 in the most constricted portion thereof; the outer diameter thereof increases in stepped fashion moving downward and upward. Forming the constrictedportions portions barrel portion 4 has left-right and front-back symmetry, therefore only one of the constrictedportions - A shown in
FIG. 9(A) , both ends 83, 83 at the front and rear of the constrictedportions corner portions 46 b. Both ends of thechannel 81 are therefore not closed, but open directly into the front andrear indentations rear indentations FIG. 9(B) , the two ends 83, 83 of theconstricted portion 54 are inwardly concavely curved more than theupper barrel portion 51 and thelower barrel portion 53 when thebarrel portion 4 is viewed from the left side. The depth at theconstricted portion 54 position is therefore shortened. - As shown in
FIG. 10 , the cross-sectional shape of thebottom face 75 a of theconcave rib 75 is dissimilar to the cross-sectional shape in theportion 100 where there is noconcave rib 75. Specifically, in the cross-sectional shape of theportion 100, the rounding radii of thecorner portions bottom face 75 a, two each of the locations corresponding to thecorner portions concave rib 75 can be increased. The reinforcing effect of the aforementionedconcave ribs - As explained above, the bottle 1 of the present embodiment enables the ease of holding a bottle 1 in one hand to be improved in a manner similar to the first embodiment. Particularly advantageous is the fact that the
constricted portion 54 allows the distance from theleft side wall 43 to theindentation 56 to be shortened, and that theconstricted portion 55 allows the distance from theleft side wall 44 to theindentation 57 to be shortened. Therefore even without opening one's hand greatly, a finger can be fit into theindentations - Referring to
FIGS. 11 through 14 , anotherbottle 110 is described. The differences with respect to the second embodiment are constricted portions and indentations. As shown inFIGS. 11 through 13 , abarrel portion 140 is between ashoulder portion 130 and abottom portion 150, and has a substantially rectangular cross-sectional shape. Anupper barrel portion 151 is an area sandwiched by twoconcave ribs lower barrel portion 153 is an area sandwiched by twoconcave ribs middle barrel portion 152 is between anupper barrel portion 151 and alower barrel portion 153, and has a center of gravity G, constrictedportions indentations -
Constricted portions right side walls portions upper barrel portion 151 and thelower barrel portion 153. The most constricted portion of the constrictedportions upper barrel portion 151 and thelower barrel portion 153. The constrictedportions corner portion 146 b, but do not reach theindentations concave channels 190 are formed up and down on the constrictedportions portions concave channels 190. - As shown in
FIG. 14 , theindentations front wall 141 and therear wall 142, separated by thecolumn portion 177. Theindentations indentations portions 154 and 155 (for example, 20 mm or greater). The depth of theindentations - With this
bottle 110, as with the above-described bottle 1, the distance from the left andright side walls indentations portions bottle 110 using theindentations indentations - Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
