ABSTRACT
Method and apparatus for forming a depression in a cover member assembled
against and closing the open end of a product filled container body comprising
a frame carrying a support that is adapted to receive and hold the assembled
cover member and container body A die is movably carried by the frame
and is adapted to cooperate with the support for engaging against the
cover member and form a depression therein inboard of the open end of the
container. Means are operatively interconnected to the frame formoving
the assembled cover member and containerbody off of the support by at least
a load relieving amount before the die forms a depression in the cover member
to relieve the support from substantially any loading during the cover
member depression forming operation. |
【要約】
本体の保持部によって蓋材と容器本体との組合せを受領し保持し、製品を満たした容器の開放端部に蓋材を組み込み、窪みを形成する方法および装置。
金型は構造部に置かれ、保持部と連動して蓋材と結合し、容器の開放端部内へ窪みを形成する。
窪み形成動作中に支持体に負荷がかからぬように、金型によって蓋材に窪みが形成される前に、装置は構造部と連携して、支持体への負荷を軽減するように、蓋材と容器容器本体との組合せを、保持部から浮かすように作動させる。 |
BACKGROUND OF THE INVENTIQN
In the automatic filling and subsequent sealing of
food containers and the like, open ended container
bodies are filled with product means and cover mem-
bers are thereafter secured over the open ends of the container bodies
to close the same.
However, it was found that prior to the complete
sealing of the cover member to such a container body,
the cover member should be stretched inboard of the
open end of~the respective container body by having a depression formed
therein so as to not only force out some of the air in the container body
prior to final seal-ing of the.cover member thereto, but also to.permit
the cover member after the same has been sealed to the container body to
expand outwardly and thereby in-crease the volumetric capacity of the completed
con-tainer construction in order to offset any adverse inter-nal pressure
forces subsequently created in the completed container construction before
such forces can destroy the sealed~ effect of the cover member thereon. |
発明の背景】
食品容器等への自動供給後に行う封止では、容器本体の開放端部に製品が満たされると、蓋材により容器開放端部が本体と一体になるように確実に閉じられる。
しかしながら、蓋材を本体へ完全に封止させる前には、蓋材が各々の容器本体の開放端部の内方へ窪むように伸ばされる必要がある。
これにより、最終封止時には容器本体内の空気が追い出される。
また蓋材を容器本体と一体化させるために、蓋材を容器の外方へ延長させ、容器構造全体の容積を増す必要がある。
これは蓋材の内側からの圧力によって、封止が破損されてしまう悪影響を相殺するためである。 |
SUMMARY
This invention provides an improved method and ap-
paratus for forming such a depression in the cover
member of the container construction.
One embodiment of the meti~od and apparatus of
this invention provides a frame carrying a support ihat
is adapted to receive and hold an assembled c6ver
membe? and container body wherein the cover
member is assembled against and closes the open end of the product filled
container body.
A die is movably carried by the frame~ and is adapted to be 'cooperable
with the support for engaging against the cover member and forming a depression
therein inboard of the open end of the container body.
Means are opera-tively interconnected to the frame for moving the as-sembled
cover member and container body off of the support by at least a load relieving
amount before the die forms the depression in the cover member~to relieve
the support from substantially any loading during the cover member depression
forming operation.
In this manner, the support can comprise a conveyor for seri-ally bringing
assembled cover members and container bodies to the depression forming
die and the action of such die on such assembled cover members and con-tamer
bodies will n6t adversely load the conveyor.
While the various features of this inventnre hereinafter described and
illustrated as being particu-larly adapted for serially forming depressions
in the cover members of product filled container bodies,
it is to be understood that the various features of this inven-tion can
be utilized singly or in' any cbmbination
thereof to pr6vide means for acting on other arucles as desired.
Therefore, this invention is not to be limited to only the embodiment illustrated
in the drawings1 because the drawings are merely utilized to illustrate
one of the wide variety of uses of this invention.
Othcr~details, uses and advantages of this invention wil4 become apparent.
a~ the following description of the present preferred embodiment thereof
in the ac-companying drawings proceeds.

【発明の概要】
この発明では、容器本体の蓋材の窪み部分を形成するための、改良された方法および装置を提供する。
本発明による方法および装置の一実施例では、満たされた容器本体の開放端部内に蓋をされるように組み合わされた蓋材と容器本体を受け取り、保持するために採用された保持体を有する構造体を提供する。
採用された金型は、構造体に置かれ、蓋材と結合し、容器本体開放端部の内側へ窪みを形成するために保持体と合致する。
本体は連動して、蓋材と容器本体との組合せを動かし、金型によって蓋材に窪みを形成する前に負荷を軽減させるために保持を離し、窪み形成動作中に、保持体がいかなる負荷をも受けないようにする。
これにより保持体は、組み合わされた蓋材と容器本体を窪み形成金型へ連続してもたらし、金型が外れないように動作するコンベアとして形成される。
以後本発明の種々の特徴が説明され、製品を満たした容器等の蓋材に、連続的に窪みを形成するために採用された構成が図示される。
本発明の種々の特徴は、単一で、あるいは様々な組合せで、必要な物品に対し使用することができるものである。
したがって、図面は本発明の広く使用できる態様の実際の一例をあらわしたものであるが、本発明は図面にあらわした実施例に限定されるものではない。
以下本発明の使用例および利点、他の詳細は、実施例において図面とともに説明される。

What is claimed is:
1. Apparatus for forming a depression in a cover
member assembled against and closing the open end of a product filled container
body comprising a frame,
a support carried by said frame and being adapted to
receive and hold the assembled cover member and con-tainer body,a die movably
