【発明の属する技術の分野】
本発明はブロー成型方法などで造形されたジュースやミネラルウォータの容器であって、特に飲み干された時その長さ方向が縮少(容積が縮少)できるようにした容器に関する。
【0002】
【従来の技術】
合成樹脂製ボトルの売り上げは、近年膨大なものになっている。しかし、容器本体内のジュースやミネラルウォータを飲み干して、該容器本体を破棄する時は飲み干す以前の形状の侭であり、これを所謂ゴミ箱に破棄する場合は、まるで空気をゴミ箱に捨てたような状態ですぐ満杯となり、あげくは路上に放棄され生活環境を悪化させる最大の欠点があり、加えてそれは飲み干された容器本体の回収費や、清掃の為の人件費は公共事業の大きな負担となっているのである。
【0003】
またこの種合成樹脂ボトルは、それをブロー成型など手軽な手段で製造できる反面、激しい振動を伴う自動車などの搬送手段や、積み重ねられる店頭での展示に見合った強度が、未だ充分とは言えないものがあった。
【0004】
さらにこの事は、容器を製造する業者からジュースやミネラルウォータを封入する会社に搬送する際も、当該容器本体が嵩ばってまるで空気を搬送しているような状態で、製品の搬送費にかかる割合は相当なものとなっていたのである。
【0005】
【発明が解決しようとする課題】
そこで本願の発明者は先に、容器本体内のジュースやミネラルウォータを飲み干して、該容器本体を破棄する時、その容積を頗る小さくすることが出来るようになしかつ、従来空の容器本体をゴミ箱に収容しきれなったのに比し、その収容個数を頗る増大させた容器を提供し多大な好評を博した。
【0006】
本発明は更にこれを改良したもので、その目的は内容物が飲み干された空の容器を、手で軽く押し潰すことができるように工夫したものであり、その押し潰し量即ち高さを頗る少くしたものであり乍ら、再び閉栓などすることなく潰された状態を保たせるようになしたことである。
【0007】
この結果、空の容器をゴミ箱に捨てるのに従来に比し多量に捨てることができ、かつそのリサイクルとして利用する為などの搬送も同時に多量に成し得るから、その回収費や清掃回収の為の人件費を頗る軽減させ得るようになったのである。
【0008】
また、容器を製造する業者からジュースやミネラルウォータを封入する会社に搬送する際も、一度の搬送量を従来の量との比較において、著しく増大させたことである。
【0009】
さらに本発明の目的は上記のように、飲干された容器を破棄する時、あるいは搬送する時、その容積を頗る小さくすることが出来るようにしたことであるが、その状態は容器本体に復元力を与えることなく、長時間あるいは長期間若しくは再利用の為の粉砕や溶解などの作業時まで、その縮少された形状を保つようにしたことである。
【0010】
【課題を解決するための手段】
而して本発明の特徴は、飲み口部分除いて長手方向の全長或いは一部が水平方向の蛇腹状となっている容器本体にあって、上記飲み口部分直下の蛇腹状部を形成する襞の形状は、その径が他方の径より小さく下方向に行くに従い各段の襞の径を順次拡大させ、容器本体の径と同等になすようにし、上記蛇腹状部を形成する各襞は、略巾広のそろばん形球状であって、上面の形状はその内面を含めて外方向に突出しており、下面の形状はその内面を含めて直線状となっておりかつ、上記襞をそろばん形球状とすることで、断面が上下に2分された形状となり、その上半分は下半分より高さを高いものとしたことである。
【0011】
而して今、かかる容器本体内のミネラルウォータなどを飲干したとする。そして飲み口部分を押し下げると、上記飲み口部分直下の蛇腹状部の形状襞の径が下方に向うに従い大径としたから、その結果押し潰された各襞はその外周辺が内周辺に対して上方となる傾斜状に重ね合せられるのである。
【0012】
また上記襞をそろばん形球状とすることで、断面上下に2分された形状となり、その上半分は下半分より高さを高いものとしたことの上下の関係で、隣に位置する襞の谷端面を圧縮することになるのである。
【0013】
そしてこの時、かかる襞の谷部が同襞の山部(径)の頂点側に押し寄せられたことに相当しこの際、襞の上面は下面に対して緩傾斜側の圧縮分力は傾斜が少ない為に下面の急傾斜側の圧力分力より大きいことから、急傾斜側の谷が山部の頂点側に移動したことになるのである。
【0014】
さらに重要なことはこの時、容器本体には2つの大きな変化が生じている。即ちその第1は、上記襞を構成する山部(径)の内径が拡大圧力で増加あるいは谷部の内径が圧縮圧力で減少すること、その第2は襞を構成する下面の直線状急傾斜面が屈曲することである。
【0015】
続いてこの急傾斜側が山部直下を通過して、さらに襞の上面の突出する緩傾斜側の内側に潜り込んで、容器本体の高さを短縮状態まで移動させ、山部の内径及び谷の内径を復元させようとする力が働き、またこの時襞の下面が上記の操作で屈曲状態となっていたものを伸展状態に復元しようとして安定した状態となるので、常に圧縮力を加えておかなくとも、本発明の容器本体はこの短縮状態を保つようになることができたのである。
【0016】
従ってかかる短縮された容器本体に、キャップを再び被冠させなくとも潰された状態を保つことができるようになったのであり、その高さ(容積)は通常のものに比べその容積を1/3乃至1/4以下とすることができ、これをゴミ箱などに放棄してもそのスペースを格段に少なくすることができたのである。
【0017】
【発明の実施の形態】
以下、図面に基づいて本発明の実施形態を説明する。
図1で(1)は容器本体で、その高さ(長さ)方向の外周と内周は蛇腹状(2)となっている。
【0018】
【実施例1】
図3と図4では上記容器本体(1)内にミネラルウォータを封入した状態で、これを飲み干して高さ(長さ)方向にその一方からあるいは両方から押し潰した状態を示した。即ち本発明はこのような容器本体(1)を押し潰した状態とするため及び潰れた状態を保つため秀れた構成を有し、秀れた作用を発揮するのである。
【0019】
その一例として図において(3)は容器本体(1)の飲み口で、その直下方は割球状(4)となっており第1段の蛇腹状(5)(即ち上記蛇腹状(2)の最上段)の外径(d1)は、容器本体(1)の外径(d)より小さい径とする。続いて第1段の蛇腹状(5)に対し第2段の蛇腹状(6)の外径(d2)は、上記第1段の蛇腹状(5)の外径(d1)より大きく容器本体(1)の外径(d)より小さい。
【0020】
さらにこれと連なりかつ上記第2段の蛇腹状(6)の外径(d2)より大きく容器本体(1)の外径より小さい第3段の蛇腹状(7)の外径(d3)となるように側面からみて階段状となっているが、勿論これは上記のように3段(5)(6)(7)とすることに限らず適宜の複数段でもよいが図1の実施例では4段とした。
【0021】
具体的に図1の容器は高さ195mm×最大直径71.5mm容量500mlの容器本体(1)にあって、12段の襞を有する形状とした。
【0022】
但しこの場合第1段の蛇腹状(5)の外径(d1)は60.5mm,第2段の蛇腹状(6)の外径(d2)は67.9mmであり、これら第1段の蛇腹状(5)と第2段の蛇腹状(6)の間の内径は、47mmとした。
【0023】
これと同様、第3段の蛇腹状(7)の外径(d3)は69.7mmであり、第2段の蛇腹状(6)と第3段の蛇腹状(7)の間の内径は51.1mmとした。また図において(8)は第4段の蛇腹状であるが、該第4段の蛇腹状(8)の外径(d)は上記容器本体(1)の最大外径である直径71.5mmであり、第3段の蛇腹状(7)と第4段の蛇腹状(8)の間の内径は54.5mmとした。また以下の第5段の蛇腹状乃至第12段の蛇腹状の襞の外径(d)は第4段の蛇腹状(8)の外径と略同一であり、それぞれの間の内径もまた第4段の蛇腹状(8)と略同一である。
【0024】
この場合上記各径は、巾広のそろばん球のような形状をしており、従って水平方向の上下に2分される。この時図1で上記第1段の襞の上(h1)下(h2)の高さは6.5mm:5.5mm,第2段の襞のそれは7mm:5mm,第3段の襞のそれは8.5mm:6.5mmとなした。
【0025】
より具体的にこれら襞の断面形状を図5で示した。これは、上記第4段の蛇腹状(8)乃至12段の蛇腹状の襞の寸法,(hx)と(hy)の例であるがその形状は各段共通なものとなっている。
【0026】
即ち図において(20)は巾広のそろばん球形状の内面も含む上面であり、(21)は巾広のそろばん球形状の内面も含む下面であるが、上面(20)の形状は外方向に突出したこの実施例では20mmRの湾状(9)となっており、これに対して下面(21)の形状は0.8mmRの突出弧状(10)を介して直線状(11)となっていることが重要なポイントである。
【0027】
本実施例のこの構成をその作用と併せて説明すると、概略上記図1の状態の容器本体(1)は、中央部(12)及び下部(13)を含む胴部(14)と上方の肩部(15)に2分され、それぞれの部位(14)(15)は、それぞれの比較に於て、その径が大径と小径の2つの径からなっていることから、安定した垂直状態を保っている。
【0028】
即ち上記中央部(12)と下部(13)を含む胴部(14)は内外径が同一の襞で形成され、肩部(15)は外観的に飲み口(3)方向が緩傾斜の凸状に湾曲され、特にこの肩部(15)は中央部(12)から飲み口(3)までの間で、襞を形成する谷部(18)の内径を徐々に減少させると共に、その傾斜角度も胴部(14)より差を大きくしたから、この中央部(12)が伸長している状態にあっては襞を形成する山(17),谷(18)の内径及び傾斜面は材料の持つ強度と弾性で伸長・伸展状態を保つことができるのである。なお底面(16)を急傾斜の凹状とすることで所謂すわりがよくなること当然である。
【0029】
さて、市販に供される容器本体(1)にはキャップ(19)が被冠されている。
そこでこのキャップ(19)を取外し、内容物を飲み干し飲み口(3)を押し下げると、図3のように肩部(15)や胴部(14)が圧縮されて縮んだ状態となる。この状態で図7に示すように肩部(15)の襞が押圧され、谷(18)の端面が上下の関係で隣に位置する襞の谷端面を圧縮することになる。この時点で襞の山(17)の頂点からみた状態では、図7,8のように両側の谷(18)部がこの山(17)の頂点側に押し寄せられたことに相当しこの際、襞の上面(20)は下面(21)に対して緩傾斜側の圧縮分力は傾斜が少ない為に下面(21)の急傾斜側の圧力分力より大きいことから急傾斜側の谷(18)が山(17)部の頂点側に移動したことになる。
【0030】
この時容器本体(1)には2つの大きな変化が生じている。即ちその第1は、上記襞を構成する山(17)部の内径が拡大圧力で増加あるいは谷(18)部の内径が圧縮圧力で減少すること、その第2は襞を構成する下面(21)の急傾斜面が屈曲することである。
【0031】
続いてこの急傾斜側が山(17)部直下を通過して、さらに図7,8でみられるように上面(20)の緩傾斜側の内側に潜り込んで、容器本体(1)の高さを短縮状態まで移動させると、山(17)の内径及び谷(18)の内径が復元する力が働き、または下面(21)が上記の操作で屈曲状態となっていたものを伸展状態に復元して安定した状態となる。従って常に圧縮力を加えておかなくとも、この短縮状態を保つようになることができたのである。
【0032】
この実施例は前記のように容器本体(1)の肩部(15)の襞の径が下方に向うに従い大径としたから、その結果押し潰された各襞はその外周辺が内周辺に対して上方となる傾斜状に重ね合せられる。
【0033】
その後飲み口(3)の上面部及び、または肩部の割球状(4)を押圧すると、その押し下げる力は図9乃至図11のように各襞の外周辺にも押し下げる力(f4)が働き、その結果図4に示すように中央部(12)及び下部(13)を含む胴部(14)の襞は、その外周辺が内周辺に対して下方となる上記肩部(15)とは逆方向の傾斜状に重ね合せられる。
【0034】
而してこの押し潰された容器本体(1)にあって肩部(15)の襞の上方の傾斜部を形成する割球状(4)及び湾状(9)と、胴部(14)の襞の下方の傾斜部が所謂「つりあって」容器本体(1)はキャップ(19)を再び被冠させなくとも潰された状態を保つことができるようになったのである。
【0035】
この結果容器本体(1)は度重なる実験では、その高さ(容積)が1/3乃至1/4以下となり、これをゴミ箱などに放棄してもそのスペースを格段に少なくすることができたのである。

[Field of the Invention]
The present invention relates to a juice or mineral water container shaped by a blow molding method or the like, and particularly to a container that can be reduced in length (reduced volume) when drunk.
[0002]
[Prior art]
Sales of synthetic resin bottles have become enormous in recent years. However, when the juice or mineral water in the container body is drunk and the container body is discarded, it is the shape of the bottle before it is drunk. When discarding this in a so-called trash box, it is as if the air was thrown into the trash box. The situation is full, and the biggest disadvantage is that it is abandoned on the street and worsens the living environment.In addition, the cost of collecting the drunk containers and the labor costs for cleaning are a major burden on public works. It has become.
[0003]
In addition, this kind of plastic bottle can be manufactured by simple means such as blow molding, but it is still not strong enough for transportation means such as automobiles with intense vibrations, and displays at the store to be stacked. There was a thing.
[0004]
Furthermore, this means that when transporting from a container manufacturer to a company that encloses juice or mineral water, the container body is bulky and it costs as much as it is transporting air. The proportion was considerable.
[0005]
[Problems to be solved by the invention]
Therefore, the inventor of the present application first dries up the juice or mineral water in the container body, and when the container body is discarded, the volume of the container body can be reduced and the conventionally empty container body is trashed. Compared to the fact that it could not be fully accommodated, it provided a container with an increased number of accommodated items and received great popularity.
[0006]
The present invention further improves this, and the object is to devise an empty container in which the contents are drunk up so that it can be lightly crushed by hand. Even though it was a little less, it was able to keep the crushed state without closing again.
[0007]
As a result, it is possible to throw away empty containers in a trash can in a larger amount than in the past, and it can also be carried in large quantities at the same time for recycling and other purposes. The labor cost can be reduced.
[0008]
Moreover, when transporting from a container manufacturer to a company that encloses juice or mineral water, the transport amount at one time is significantly increased in comparison with the conventional amount.
[0009]
Further, the object of the present invention is to reduce the volume of the drunk container when it is discarded or transported as described above, but its state is restored to the container body. This means that the reduced shape is maintained for a long time, for a long period of time, or until a work such as pulverization or dissolution for reuse without applying force.
[0010]
[Means for Solving the Problems]
Thus, the present invention is characterized in that the entire length in the longitudinal direction or a part of the container body excluding the mouthpiece portion is a horizontal bellows-like shape, and the bellows-like portion directly below the mouthpiece portion is formed. The shape of the diameter is smaller than the diameter of the other, and the diameter of the ridges of each stage is sequentially expanded as it goes downward, so that the diameter of each ridge is equivalent to the diameter of the container body. It is an almost wide abacus-shaped sphere, the shape of the upper surface protrudes outward including its inner surface, the shape of the lower surface is a straight line including its inner surface, and the heel is shaped like an abacus-shaped sphere. As a result, the cross-section is divided into two parts vertically, and the upper half has a higher height than the lower half.
[0011]
Suppose now that the mineral water in the container body has been drunk. And when the mouth part is pushed down, the shape of the bellows-like part immediately below the mouth part becomes larger as the diameter of the corrugated part goes downward. Thus, they are superposed in an upwardly inclined shape.
[0012]
In addition, by making the ridges into abacus-shaped spheres, the cross-section is divided into two halves, and the upper half of the upper half is higher than the lower half. The end face is compressed.
[0013]
At this time, this trough valley corresponds to the fact that the trough of the trough is pushed toward the apex side of the crest (diameter) of the trough. At this time, the compression component force on the gentle slope side of the top surface of the trough is inclined. Because it is less than the pressure component on the steep slope side of the lower surface, the steep slope valley has moved to the top of the peak.
[0014]
More importantly, there are two major changes in the container body at this time. That is, the first is that the inner diameter of the crest (diameter) constituting the ridge increases with the expansion pressure or the inner diameter of the trough decreases with the compression pressure, and the second is the linear steep slope of the lower surface constituting the ridge. The surface is bent.
[0015]
Subsequently, the steeply inclined side passes directly under the peak, and further enters the inside of the gently inclined side where the upper surface of the ridge protrudes, and the height of the container body is moved to a shortened state. At this time, the bottom surface of the bag is in a stable state trying to restore the bent state by the above operation, so it is not necessary to apply compressive force at all times. At the same time, the container body of the present invention was able to maintain this shortened state.
[0016]
Therefore, the shortened container body can be kept in a crushed state without re-crowning the cap, and its height (volume) is reduced to 1 /. It could be 3 to 1/4 or less, and even if it was abandoned in a trash can, the space could be remarkably reduced.
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, (1) is a container main body, and the outer periphery and inner periphery of the height (length) direction become a bellows shape (2).
[0018]
[Example 1]
3 and 4 show a state in which the mineral water is enclosed in the container body (1), and the bottle is swallowed and crushed from one or both in the height (length) direction. In other words, the present invention has an excellent structure to bring such a container body (1) into a crushed state and keep the crushed state, and exhibits an excellent action.
[0019]
As an example, in the figure, (3) is a drinking mouth of the container main body (1), and immediately below it is a split ball (4), which is a first bellows shape (5) (that is, the bellows shape (2) above). The outer diameter (d1) of the uppermost stage is smaller than the outer diameter (d) of the container body (1). Subsequently, the outer diameter (d2) of the second step bellows shape (6) is larger than the outer diameter (d1) of the first step bellows shape (5) with respect to the first step bellows shape (5). It is smaller than the outer diameter (d) of (1).
[0020]
Further, the outer diameter (d3) of the third step bellows (7) is larger than the outer diameter (d2) of the second step bellows (6) and smaller than the outer diameter of the container body (1). However, this is not limited to the three steps (5), (6), and (7) as described above, but may be an appropriate plurality of steps, but in the embodiment of FIG. There were four stages.
[0021]
Specifically, the container of FIG. 1 is in a container main body (1) having a height of 195 mm × a maximum diameter of 71.5 mm and a capacity of 500 ml, and has a shape having 12-stage ridges.
[0022]
In this case, however, the outer diameter (d1) of the first stage bellows (5) is 60.5 mm, and the outer diameter (d2) of the second stage bellows (6) is 67.9 mm. The inner diameter between the bellows shape (5) and the second bellows shape (6) was 47 mm.
[0023]
Similarly, the outer diameter (d3) of the third stage bellows (7) is 69.7 mm, and the inner diameter between the second stage bellows (6) and the third stage bellows (7) is It was set to 51.1 mm. Further, in the figure, (8) is a fourth step bellows shape, and the outer diameter (d) of the fourth step bellows shape (8) is 71.5 mm in diameter which is the maximum outer diameter of the container body (1). The inner diameter between the third step bellows (7) and the fourth step bellows (8) was 54.5 mm. In addition, the outer diameter (d) of the following fifth-stage bellows-shaped to twelfth-stage bellows-shaped ridges is substantially the same as the outer diameter of the fourth-stage bellows-shaped collar (8), and the inner diameter between them is also the same. It is substantially the same as the fourth stage bellows shape (8).
[0024]
In this case, each of the above-mentioned diameters has a shape like a wide abacus, and is thus divided into two parts in the horizontal direction. At this time, in FIG. 1, the height of the upper (h1) and lower (h2) of the first stage ridge is 6.5 mm: 5.5 mm, that of the second stage ridge is 7 mm: 5 mm, and that of the third stage ridge is 8.5 mm: 6.5 mm.
[0025]
More specifically, the cross-sectional shape of these ridges is shown in FIG. This is an example of the dimensions of the fourth step bellows-shaped (8) to twelve-step bellows-shaped ridges, (hx) and (hy), but the shape is common to each step.
[0026]
That is, in the figure, (20) is the upper surface including the inner surface of the wide abacus sphere shape, and (21) is the lower surface including the inner surface of the wide abacus sphere shape, but the shape of the upper surface (20) is outward. In this projecting example, the shape is a bay shape (9) of 20 mmR, whereas the shape of the lower surface (21) is linear (11) through a projecting arc shape (10) of 0.8 mmR. This is an important point.
[0027]
Describing this configuration of the present embodiment together with its operation, the container body (1) in the state of FIG. 1 is generally composed of a trunk portion (14) including a central portion (12) and a lower portion (13), and an upper shoulder. The part (15) is divided into two parts, and the respective parts (14) and (15) are composed of two diameters, a large diameter and a small diameter. I keep it.
[0028]
In other words, the body (14) including the central portion (12) and the lower portion (13) is formed with the same inner and outer diameters, and the shoulder portion (15) is convexly convex in the direction of the drinking mouth (3). In particular, the shoulder (15) gradually decreases the inner diameter of the valley (18) forming the ridge between the central portion (12) and the drinking mouth (3), and the inclination angle thereof. Since the difference is larger than that of the body (14), the inner diameter and the inclined surface of the peaks (17) and valleys (18) forming the ridges are made of the material when the central portion (12) is extended. It is possible to maintain the stretched and stretched state with its strength and elasticity. In addition, it is natural that the so-called sitting is improved by making the bottom surface (16) have a steeply concave shape.
[0029]
Now, a commercially available container body (1) is covered with a cap (19).
Therefore, when the cap (19) is removed, the contents are dried and the drinking mouth (3) is pushed down, the shoulder (15) and the trunk (14) are compressed and contracted as shown in FIG. In this state, as shown in FIG. 7, the collar of the shoulder (15) is pressed, and the end face of the trough (18) is compressed in the trough end face located next to it in the vertical relationship. At this point, the state seen from the top of the mountain (17) corresponds to the fact that the valleys (18) on both sides are pushed toward the top of the mountain (17) as shown in FIGS. The upper surface (20) of the kite has a lower slope (18) than the lower surface (21), so the compression component force on the gentle slope side is less so that the pressure component force on the steep slope side of the lower surface (21) is larger. ) Has moved to the top of the mountain (17).
[0030]
At this time, two major changes occur in the container body (1). That is, the first is that the inner diameter of the crest (17) constituting the ridge increases with the expansion pressure or the inner diameter of the trough (18) decreases with the compression pressure, and the second is the lower surface (21 ) Steeply inclined surfaces are bent.
[0031]
Subsequently, the steeply inclined side passes directly under the mountain (17), and further sinks inside the gently inclined side of the upper surface (20) as seen in FIGS. 7 and 8, so that the height of the container body (1) is increased. When it is moved to the shortened state, the force that restores the inner diameter of the peak (17) and the inner diameter of the valley (18) works, or the lower surface (21) that has been bent by the above operation is restored to the extended state. In a stable state. Therefore, even if the compression force is not always applied, this shortened state can be maintained.
[0032]
In this embodiment, as described above, the diameter of the ridge of the shoulder (15) of the container body (1) is increased as it goes downward. As a result, each of the crushed folds has an outer periphery on the inner periphery. On the other hand, they are superimposed in an upwardly inclined shape.
[0033]
After that, when the upper surface of the drinking mouth (3) and the split ball (4) of the shoulder are pressed, the pressing force is the pressing force (f4) on the outer periphery of each bag as shown in FIGS. As a result, as shown in FIG. 4, the heel of the trunk portion (14) including the central portion (12) and the lower portion (13) is different from the shoulder portion (15) whose outer periphery is below the inner periphery. Overlapping in the reverse direction.
[0034]
Thus, in the crushed container body (1), the split ball (4) and the bay shape (9) forming the inclined portion above the collar of the shoulder portion (15), and the trunk portion (14) The so-called “balanced” sloped portion of the lower part of the heel can keep the container body (1) in a crushed state without having to cap the cap (19) again.
[0035]
As a result, the container body (1) has a height (volume) of 1/3 to 1/4 or less in repeated experiments, and even if it is abandoned in a trash can, the space can be remarkably reduced. It is.
