Abstract
Description
- The present invention relates to a bottle for aseptic filling having a spout (mouth) portion, a shoulder portion, a body portion and a bottom portion.
- As a method of filling a plastic bottle with liquid, there is an aseptic (germfree) filling method which fills a bottle with liquid under an aseptic condition. With this aseptic filling method, it is possible to avoid exposure of the plastic bottle to a high temperature. Thus, a plastic bottle filled by such aseptic filling method (to be referred to as “aseptic filling bottle” hereinafter) can have low heat resistance, and can be formed as a thin and lightweight bottle.
- However, when a bottle is formed thin and lightweight, there arises a problem of corresponding reduction in its strength. Thus, in a case where its inside is filled with carbonated beverage for instance, rise of inner pressure occurs due to outgassing of carbonate inside, which may cause reversal (buckling) of the bottom portion. With occurrence of such buckling, the bottle can no longer stand on its own, thus making its distribution impossible. To cope with problem, Japanese Unexamined Patent Application No. 2012-140156 Publication Document (Patent Document 1) proposed a bottle that can suppress occurrence of bottom portion buckling by provision, at the center of the bottom portion, of a dome-shaped receded portion receded to the inner side.
- Patent Document 1: Japanese Unexamined Patent Application No. 2012-140156 Publication Document
- A plastic bottle filled with contents may not only be stored at a room temperature or in refrigeration, but also may be stored at an elevated temperature or stored under refrigeration, with heating or freezing of its contents. However, in the case of such heated storage or refrigerated storage, expansion occurs in the contents due to heating/refrigerating, which can cause buckling of the bottom portion. Moreover, in the case of adoption of such arrangement as proposed by
Patent Document 1, there was another problem of difficulty of weight reduction. - Therefore, there is a need for an aseptic filling bottle that can suppress buckling of its bottom portion even at the time of heated storage or refrigerated storage.
- An aseptic filling bottle relating to the present invention, the aseptic filling bottle including a spout portion, a shoulder portion, a body portion and a bottom portion;
- wherein the bottom portion includes a grounding portion to be placed in contact with a surface on which the bottle is put, a central portion that projects to an inner side of the bottle as its extends radially inwards from the grounding portion, a dome portion which projects to more inner side of the bottle than the central portion, and a receded groove portion that extends radially from the dome portion;
- wherein a bottom inner side projection height of the central portion at a dome portion side circumferential edge thereof is set greater than a half of a height from the grounding portion to a border between the body portion and the bottom portion; and
- wherein the receded groove portion, at a position corresponding to the radial center position of the grounding portion, has a depth ranging from 5.0 mm to 10.0 mm.
- Based on a finding made by the present inventors, by not forming the center of the central portion alone in the form of a dome projecting to the bottle inner side, but by configuring the central portion entirely, with keeping the dome shape at its center, from the dome portion side circumferential edge to the grounding portion to project to the bottle inner side as it extends to the radial inner side, the strength of the bottle bottom portion can be further increased. According to a further finding made by the present inventors, when the maximum projection height of the central portion, namely, its projection height to the bottle inner side at the dome portion side circumferential edge, is set greater than a half of the height of the bottom portion, the effect of strength increase can be further enhanced.
- In addition, with the above-described configuration, according to the arrangements devised by the present inventors, i.e. the arrangement of forming the central portion to project to the bottle inner side as it extends radially inwards from the grounding portion and the further arrangement of setting the projection height to the bottle inner side at the dome portion side circumferential edge greater than a half of the height of the bottom portion (i.e. the height to the border between the body portion and the bottom portion), the strength of the bottom portion can be enhanced effectively. With this, the buckling of the bottom portion at the time of refrigerated storage can be effectively suppressed.
- Moreover, the receded groove portion formed radially from the central portion provides further reinforcement of the bottom portion, and since the receded groove portion has a depth ranging from 5.0 mm to 10.0 mm at a position corresponding to the radial center position of the grounding portion, the strength of the bottom portion can be even more enhanced. In addition, with this depth setting, buckling of the bottom portion can be suppressed also even when the bottle is heated.
- Next, preferred embodiments of the aseptic filling bottle relating to the present invention will be explained. It is understood, however, that the range of the present invention is not limited by the preferred embodiments described below.
- According to one preferred embodiment, the central portion is formed arcuate.
- With this arrangement, by forming arcuate the central portion to be projected to the bottle inner side, compared with an arrangement of forming the central portion linear from the grounding portion to the dome portion circumferential edge, pressure applied to the central portion can be made uniform, so that the strength of the bottom portion can be increased even more effectively. With this, the buckling of the bottom portion at the time of refrigerated storage can be suppressed even more effectively.
- According to a further preferred embodiment, the receded groove portion extends from the dome portion to a circumferential edge on more radial outer side than the grounding portion.
- With this arrangement, as the receded groove portion for reinforcing the strength of the bottom portion is caused to extend long from the dome portion to the circumferential edge, the strength of the bottom portion can be even more increased.
- According to a further preferred embodiment, in the body portion, there is formed at least one receded rib which extends around a circumferential face of the body portion.
- With the above-described arrangement, volumetric expansion of contents at the time of refrigerated storage can be absorbed to a certain extent by the receded rib provided in the body portion. Thus, the force applied to the appropriate portion due to the volumetric expansion can be reduced, so that the buckling of the bottom portion at the time of refrigerated storage can be suppressed effectively.

FIG. 1 is a front view of an aseptic filling bottle, -
FIG. 2 is a bottom view of a bottom portion of the aseptic filling bottle, -
FIG. 3 shows a III-III section inFIG. 2 , and -
FIG. 4 shows a IV-IV section inFIG. 2 . - Embodiments of an aseptic filling bottle relating to the present invention will be explained with reference to the drawings. An
aseptic filling bottle 1 relating to this embodiment includes a spout (mouth) portion 2, ashoulder portion 4, abody portion 5 and abottom portion 6. Thebottom portion 6 includes agrounding portion 10 that comes into contact with a surface on which the bottle is put, acentral portion 12 that progressively projects to the inner side of the bottle main body as it extends from thegrounding portion 10 to the center of thebottom portion 6, adome portion 13 that projects more to the bottle inner side than thecentral portion 12, and a recededgroove portion 14 that extends radially from thedome portion 13. Thecentral portion 12 is configured such that a bottle inner side projection height D1 of thiscentral portion 12 at a dome portion sidecircumferential edge 12 a thereof is set greater than a half D2 of a height measured from thegrounding portion 10 to the border between thebody portion 5 and thebottom portion 6. Moreover, the recededgroove portion 14, at a position corresponding to the radial center position of thegrounding portion 10, has a depth D3 ranging from 5.0 mm to 10.0 mm. With these arrangements, buckling of the bottom portion at the time of refrigerated storage can be effectively suppressed. Next, the aseptic filling bottle relating to this embodiment will be explained in details. - The
aseptic filling bottle 1 relating to this embodiment (to be referred to simply as “bottle 1” hereinafter), as shown inFIG. 1 , includes the spout portion 2 as a spout or a mouse for dispensing liquid and a bottlemain body portion 3 to be filled with the liquid. The bottlemain body portion 3 includes theshoulder portion 4, thebody portion 5 and thebottom portion 6. Theshoulder portion 4 is a portion whose diameter increases progressively toward a bottom face direction continuous with the spout portion 2 and has a shape formed of combination of polygonal panels of various shapes. Thebody portion 5 is a cylindrical portion continuous with theshoulder portion 4. Thebottom portion 6 is a portion in the bottlemain body portion 3, where the circumferential face of the bottlemain body portion 3 has its diameter progressively decreasing toward the bottom face. Namely, in the instant embodiment, the position of the border between thebody portion 5 and thebottom portion 6 is a position in the height direction where the diameter of the bottlemain body portion 3 begins to decrease toward the bottom face. - Here, the
bottle 1 relating to the instant embodiment is a bottle for use in an aseptic (germfree) filling method for filling liquid inside a bottle under an aseptic condition. The aseptic filling method allows avoiding exposure of a plastic bottle to a high temperature. So, the heat resistance performance of thebottle 1 can be low and this bottle is formed as a thin and lightweight bottle. Thebottle 1 can be molded integrally, e.g. by the biaxial stretch blow molding method with using a thermoplastic resin such as polyethylene, polypropylene, polyethylene terephthalate, etc. as a principal material. - The
bottle 1 relating to this embodiment, as will be described below, is configured to withstand filled contents expansion when the filled (charged) liquid is frozen. Thus, as contents to be filled in thebottle 1, e.g. non-carbonated beverage such as mineral water, tea, soft drink, or juice, which may be stored under a refrigerated state are particularly preferred. However, the bottle may be used suitably also with a carbonated drink (beverage) or a food article such as sauce. - The
body portion 5 is of a straight body type and in thisbody portion 5, there are formed a plurality of recededribs 7 that extend around its circumferential face. Each recededrib 7 has a shape receded or concave to the inner side in the radial direction (the direction toward a center axis X of thebottle 1 and along its horizontal direction) and the width and the depth of each recededrib 7 are formed approximately constant over the entire circumference. These recededribs 7 function not only as reinforcing ribs for reinforcing the lateral face strength of thebottle 1, but also as portions extendible in the vertical upper direction of thebottle 1 for absorbing possible volumetric expansion of the contents liquid at the time of refrigerated storage. - Incidentally, as such receded
ribs 7, it will suffice to provide at least one at any position of thebody portion 5. Preferably, two or moresuch ribs 7 will be formed in thebody portion 5. More preferably, at least one will be formed at a lower part of the body portion and a plurality will be formed at an upper part of the body portion. Incidentally, if at least one is formed at the body portion lower part and the body portion upper part respectively, this will allow smooth and easy extension in the vertical upper direction of thebottle 1 for absorbing the volumetric expansion of the contents liquid at the time of refrigerated storage. So, thebottle 1 can stand straight on its own without tilting and also no deformation or break of the bottle will occur, either. Further, as shown inFIG. 1 , advantageously, the recededrib 7 may be formed to be receded/concave to the radially inner side and along the entire circumference. - As shown in
FIGS. 1 through 4 , thebottom portion 6 has anannular grounding portion 10 to be placed on (in contact with) a surface on which the bottle is put such as a desk surface and includes also acircumferential edge portion 11 which is a portion on the radially outer side of the groundingportion 10, acentral portion 12 that is a radially inner side portion relative to the groundingportion 10 and adome portion 13 that is provided at thecentral portion 12 and that projects to more bottle inner side than thecentral portion 12. Thecentral portion 12 has such a shape that projects to the inner side (the upper side inFIG. 1 ) of thebottle 1 as it extends to radially inner side from the groundingportion 10 and is formed arcuate from the groundingportion 10 to thedome portion 13. Further, as shown inFIG. 3 , thecentral portion 12 is configured such that the bottle inner side projection height D1 of thiscentral portion 12 at the dome portion sidecircumferential edge 12 a thereof is set greater than the half D2 of the height measured from the groundingportion 10 to theborder 6 a between thebody portion 5 and thebottom portion 6. Moreover, thedome portion 13 is provided in a trapezoidal shape as seen in its vertical section. - In the
bottom portion 6, there are formed a plurality (eight in this embodiment) of the recededgroove portions 14 extending from thedome portion 13 to thecircumferential edge portion 11 equidistantly in a radial pattern. With these recededgroove portions 14, the strength of thebottom portion 6 is increased. With the provision of these recededgroove portions 14, thecircumferential edge portion 11 and thecentral portion 12 are divided into a plurality (eight in the present embodiment) in the circumferential direction (the direction around the center axis X of the bottle 1). As shown inFIG. 4 , anend portion 14 a of each recededgroove portion 14 on the side of thecircumferential edge portion 11 extends to theborder 6 a between thebody portion 5 and thebottom portion 6. Further, preferably, the recededgroove portion 14 is configured such that the recededgroove portion 14, at a position corresponding to the radial center position of the groundingportion 10, has the depth D3 ranging from 5.0 mm to 10.0 mm (6.6 mm in this embodiment). If it exceeds 10.0 mm, the depth will be excessive to invite impairment of the outer appearance of thebottle 1 or to invite need for design change of some other portion. - As described above, in the
bottle 1, the arrangement of not only forming thedome portion 13 at the center of thebottom portion 6, but also configuring the entirecentral portion 12 from thedome portion 13 to the groundingportion 10 to project to the bottle inner side as extending to the radially inner side, the arrangement of setting the projection height at the dome portion sidecircumferential edge 13 a greater than the half of the height of thebottom portion 6, and the arrangement of forming arcuate from the groundingportion 10 to the dome portion sidecircumferential edge 13 a together serve to effectively increase the strength of thebottom portion 6. Moreover, the strength of thebottom portion 6 is further increased by the recededgroove portions 14 that extend from thedome portion 13 to thecircumferential edge portion 11. With this, there is ensured strength sufficient to effectively suppress buckling of thebottom portion 6 due to volumetric expansion of the contents at time of refrigerated storage. - Table 1 below shows comparison of three-times tests of a conventional bottle and the
bottle 1 relating to the present embodiment. As shown, with the conventional bottle, unlike thebottle 1 relating to the present embodiment, the depth of the portion corresponding to the depth D3 shown inFIG. 3 (the depth at the position of the recededgroove portion 14 corresponding to the radial center of the grounding portion 10) is below 5 mm. -
TABLE 1 Embodiment Conventional filling amount (ml) 650 490 N = 1 Pass Pass N = 2 Pass Failure N = 3 Pass Failure Pass: The bottle stands stably after refrigeration. Failure: The bottle does not stand stably after refrigeration. - As can be seen from Table 1, the
bottle 1 relating to the present embodiment is more stable in the case of the large-volume bottle having a filling amount of 650 ml, this means the suppression of buckling of thebottom portion 6. In this way, it may be understood that with thebottle 1 relating to the present embodiment, strength sufficient to suppress the buckling of thebottom portion 6 due to volumetric expansion of the contents at time of refrigerated storage (and also heated storage) is ensured. - Lastly, other embodiments of the aseptic filling bottle relating to the present invention will be explained. Incidentally, the arrangements/configurations disclosed in the respective following embodiments can be used in any combination with the arrangements/configurations disclosed in the other embodiments unless no contradiction occurs resulting therefrom.
- (1) In the foregoing embodiment, there was explained an example in which the
body portion 5 is configured as a straight body type. However, the present invention is not limited thereto. For instance, thebody portion 5 may be provided with a constricted portion, in addition to the straight body portion. - (2) In the foregoing embodiment, between the respective receded
groove portions 14, a receded small groove portion smaller than the recededgroove portion 14 may be provided additionally from the groundingportion 10 to thecircumferential edge portion 11. With this, the strength of the bottom portion can be further increased. - (3) Further, regarding the other arrangements/configurations too, it is understood that the embodiments disclosed in this detailed disclosure are only illustrative in all respects thereof, and the scope of the present invention is not limited thereto. One skilled in the art could easily understand that appropriate modifications will be possible within the scope not departing from the spirit of the invention. Therefore, it is as a matter of course that other embodiments with such modifications not departing form the spirit of the invention are also included in the scope of the present invention.
