Description

本発明は、カップ状耐熱容器に関するものである。   The present invention relates to a cup-shaped heat-resistant container.

カップ状の耐熱容器として、口部上端のフランジと、漸次縮径された胴部と、中央部をドーム状の肉厚の天頂部として外周部を平坦面とした底部とを具備した容器、或いは、底部中央部に中心部から稜線が放射状に延びる花弁状の凸部を形成し、底部の耐熱強度を向上させるようにした容器は、従来より知られている(例えば、特許文献1参照)。
特開2004−331104号公報
As a cup-shaped heat-resistant container, a container having a flange at the upper end of the mouth portion, a gradually reduced diameter body portion, and a bottom portion having a central portion as a dome-shaped thick zenith portion and an outer peripheral portion as a flat surface, or A container in which a petal-like convex part whose ridgeline extends radially from the center part at the center part of the bottom part to improve the heat resistance strength of the bottom part has been conventionally known (see, for example, Patent Document 1).
JP 2004-331104 A

しかし、特許文献1記載の容器は、底中央部から放射状に延びる凸条があるため、積み重ねられた容器を分離するときに、吸引の妨げとなり、生産性がよくないという問題があった。   However, since the container described in Patent Document 1 has ridges extending radially from the center of the bottom, there has been a problem that when separating stacked containers, suction is hindered and productivity is not good.

本発明は、上記問題を解決することを課題として、熱殺菌、加熱充填時に、容器が熱変形して、底部が変形して自立性が劣化することがなく、積み重ねが簡単にできるとともに、底部中央部を吸引して個々に分離することが容易にできるカップ状容器を提供することを目的とする。   It is an object of the present invention to solve the above problems, and during heat sterilization and heat filling, the container is thermally deformed, the bottom is not deformed and the self-supporting property is not deteriorated, and stacking can be easily performed. An object of the present invention is to provide a cup-shaped container that can be easily separated by sucking the central portion.

本発明は、上記の課題を解決するため、カップ状耐熱容器として、鍔部と口部周壁、胴部と底部とからなるカップ状耐熱容器であって、胴部は、下方にいくにしたがって漸次縮径されるテーパー部となっており、底部は、下方へ膨出する周辺部と、平滑状の中央部とからなり、周辺部は、複数の脚部と、脚部間に形成された谷部とを具え、谷部には、中央部から延びる放射状のリブが設けられ、中央部は、平板状、もしくはゆるやかに上方へ突出形成した平滑面になっていることを特徴とする構成を採用する。 In order to solve the above-mentioned problem, the present invention is a cup-shaped heat-resistant container comprising a collar part, a mouth peripheral wall, a body part, and a bottom part as a cup-shaped heat-resistant container, and the body part gradually moves downward. It is a tapered part that is reduced in diameter, and the bottom part is composed of a peripheral part that bulges downward and a smooth central part. The peripheral part is a plurality of legs and a valley formed between the legs. The trough is provided with radial ribs that extend from the center , and the center is flat or has a smooth surface that protrudes gently upwards. To do.

本発明のカップ状耐熱容器は、その底部が、下方へ膨出する周辺部と平滑状の中央部とからなり、底部周辺部は、数個の脚部と、脚部間に形成された谷部とを具え、谷部には中央部から延びる放射状のリブが設けられているから、熱殺菌、加熱充填等により熱変形し、底部が落ち直立性が劣化することはない。   The cup-shaped heat-resistant container according to the present invention has a bottom portion that includes a peripheral portion that bulges downward and a smooth central portion. The bottom peripheral portion includes a plurality of leg portions and a valley formed between the leg portions. Since the ribs are provided with radial ribs extending from the central portion, the bottom portion is not thermally deformed by heat sterilization, heat filling, etc., and the uprightness is not deteriorated.

また、胴部は、下方にいくにしたがって漸次縮径されるテーパー部となっており、底部中央部は平滑状になっているので、重なった状態で搬送している容器の底部を、バキュームして個々に分離することができ、充填ライン上で並列させることが容易にできる。   In addition, since the body portion is a tapered portion that gradually decreases in diameter as it goes downward, and the center portion of the bottom portion is smooth, the bottom portion of the container that is being transported in an overlapping state is vacuumed. Can be separated individually and can be easily arranged in parallel on the filling line.

次に、本発明のカップ状耐熱容器について図面を参照して説明する。
図1〜3に示すように、本発明のカップ状耐熱容器は、鍔部1と口部周壁2と胴部3と底部4とから構成されている。
Next, the cup-shaped heat-resistant container of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the cup-shaped heat-resistant container of the present invention includes a flange 1, a mouth peripheral wall 2, a body 3, and a bottom 4.

鍔部1は、胴部3の肉厚と同等、もしくはやや肉厚に形成され、口部周壁2は、上端に鍔部1を設け、胴部3に連なり胴部3より大径に形成されている。
胴部3は、断面円形で下方にいくにしたがって、漸次縮径するテーパー部5によって形成されている。
The collar part 1 is formed to be equal to or slightly thicker than the thickness of the trunk part 3, and the mouth peripheral wall 2 is provided with the collar part 1 at the upper end and is connected to the trunk part 3 and has a larger diameter than the trunk part 3. ing.
The trunk portion 3 is formed by a tapered portion 5 having a circular cross section and gradually decreasing in diameter as it goes downward.

底部4は、下方へ膨出した周辺部6と、平滑状の中央部7とからなり、周辺部6には、胴部3に連なった数個の脚部8と、脚部8間に形成された谷部9が形成され、谷部9底面には、中央部7から側面に向かって放射状に延びるリブ10が設けられている。   The bottom part 4 includes a peripheral part 6 bulging downward and a smooth central part 7. The peripheral part 6 is formed between several leg parts 8 connected to the body part 3 and the leg parts 8. The valley portion 9 is formed, and ribs 10 extending radially from the central portion 7 toward the side surface are provided on the bottom surface of the valley portion 9.

次に、上記構成に基づく作用効果について説明する。
本発明のカップ状耐熱容器は、茶、紅茶、コーヒー等の飲料類の加熱充填用として使用され、充填工程において、熱殺菌、加熱充填がおこなわれる。
充填ラインには、カップ状容器は重なった状態で搬送されてくるが、個々に分離され、充填ラインに並列される。
Next, the effect based on the said structure is demonstrated.
The cup-shaped heat-resistant container of the present invention is used for heating and filling beverages such as tea, tea, and coffee, and heat sterilization and heating filling are performed in the filling step.
The cup-shaped containers are transported to the filling line in an overlapping state, but are separated individually and juxtaposed to the filling line.

その際、底部4が、下方へ膨出した周辺部6と、平滑状の中央部7と、周辺部6に設けた数個の脚部8間に形成された谷部9を補強する放射状のリブ10により補強されているので、熱殺菌、加熱充填時に、熱変形し、底部4が落ちて自立性が劣化することがなくなった。   At that time, the bottom 4 is a radial portion that reinforces a peripheral portion 6 that bulges downward, a smooth central portion 7, and a trough 9 formed between several leg portions 8 provided in the peripheral portion 6. Since it is reinforced by the rib 10, it is not thermally deformed at the time of heat sterilization and heat filling, and the bottom part 4 falls and the self-supporting property is not deteriorated.

胴部3が、断面円形で下方にいくにしたがって漸次縮径されているテーパー部5により構成されているので、重なった状態で搬送可能になり、また、脚部8が、底部周辺部6に設けられ、重なった状態で搬送しているカップ状容器の底部4の中央部7が平滑面となっているので、吸盤等によるバキュームがより一層容易となり、容器を個々に分離することが可能になった。   Since the body portion 3 is formed by the tapered portion 5 having a circular cross section and being gradually reduced in diameter as it goes downward, the body portion 3 can be conveyed in an overlapping state, and the leg portion 8 is attached to the bottom peripheral portion 6. The central part 7 of the bottom 4 of the cup-shaped container that is provided and transported in an overlapped state has a smooth surface, so that vacuuming with a suction cup or the like is further facilitated and the containers can be separated individually. became.

さらに、底部4の中央部7の平滑面を、望ましくは平板状にすればより一層吸盤等によるバキュームが可能となり、容器を個々に分離することが容易となった。   Furthermore, if the smooth surface of the central portion 7 of the bottom portion 4 is desirably flat, vacuuming with a suction cup or the like becomes possible, making it easier to separate the containers individually.

また、底部4の中央部7の平滑面を、ゆるやかに上方へ突出形成しても同様の効果が得られるのである。
なお、平滑面は、バキューム器具の吸着部以上の広さがあればよく、とくに直径15mm以上の円形領域とするのが好ましい。
The same effect can be obtained even if the smooth surface of the central portion 7 of the bottom portion 4 is formed so as to gently protrude upward.
The smooth surface only needs to be larger than the suction part of the vacuum device, and is preferably a circular region having a diameter of 15 mm or more.

カップ状耐熱容器を、周辺部と放射状のリブで補強した谷部と、底部中央を平滑面にする簡単な構造により、熱殺菌や加熱充填等により熱変形せず、しかも充填ライン上で重なった容器をバキュームして個々に分離可能とされるので、生産性が上昇し、コスト低減が図れ、低廉に提供できるので、加熱された飲料製品が収納されるカップ状容器として広く利用できる。
また、飲料以外の食品、その他の内容物にも、好適に利用できる。
The cup-shaped heat-resistant container is not deformed by heat sterilization, heat filling, etc., and overlaps on the filling line due to the simple structure with the valley part reinforced by the peripheral part and radial ribs, and the bottom center as a smooth surface. Since the containers can be vacuumed and separated individually, the productivity can be increased, the cost can be reduced, and the containers can be provided at low cost. Therefore, the containers can be widely used as cup-shaped containers for storing heated beverage products.
Moreover, it can utilize suitably also for foodstuffs other than a drink, and other contents.
