CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] Not applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not applicable.
NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT
[0003] Not applicable.
INCORPORATION-BY-REFERENCE OF MATERIALS SUBMITTED ON A COMPACT
DISC
[0004] Not applicable.
BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] The present invention relates to a container for containing
foods, medical and pharmaceutical products, etc. More particularly,
the present invention relates to a container having a cover, said
cover being attached to an end of said container, said cover being
not attachable again to said end of said container once said cover
is detached from said end of said container.
[0007] In the present invention, foods, medical and pharmaceutical
products, etc. contained in the container are hereinafter referred
to as "contents".
[0008] In the present invention, a cover may be attached to an
upper end, lower end or any other end of the container.
[0009] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
[0010] Various containers having a cover and made of a paper or
synthetic resin, have been used for containing contents such as
foods and medical and pharmaceutical products.
[0011] Japanese Patent Laid-Open Publication No. Hei 9-20354,
published on Jan. 21, 1997, discloses a cover for a paper can. Said
cover is attached to an open end of a cylindrical paper can. Said
paper can may be used for containing foods, medical and
pharmaceutical products, etc.
[0012] The cover of the abovementioned conventional containers can
be easily detached from the container. The containers are shipped,
transported, warehoused and displayed with the contents contained
therein. Therefore, a third person may detach the cover from the
container; illegally put a harmful object, filthy thing or other
foreign matter into the container or illegally remove the contents
from the container, and then reattach the cover to the
container.
[0013] In the abovementioned conventional containers, it is easy to
detach the cover from the container and attach the cover thereto
again. Even if the cover has been detached from the container and
attached thereto again, this fact cannot be confirmed by the
appearance alone of the cover or the container. As a result, a
purchaser may take the contents out of the container and eat or
drink the contents without knowing said fact. The foreign matter
illegally put into the container by the third person may give an
adverse result to the purchaser. Furthermore, the purchaser is
likely to be anxious that a foreign matter may have been illegally
put into the container before he purchases the product.
[0014] Thus, in the abovementioned conventional containers, it is
impossible to give consumers safety and freedom from anxiety.
BRIEF SUMMARY OF THE INVENTION
[0015] It is an object of the invention to provide a container
having a cover, said cover being attached to an end of said
container, said cover being not attachable again to said end of
said container once said cover is detached from said end of said
container.
[0016] It is another object of the invention to provide a container
which gives consumers safety and freedom from anxiety.
[0017] These and other objects have been achieved by the following
container.
[0018] The present invention is a container having a cylindrical
body and a cover attached to an end of said cylindrical body. Said
end of said cylindrical body is provided on the inside with an
annular thicker portion. Said cover comprises a substantially
circular plate portion, said plate portion being provided on one
side with a substantially cylindrical portion. Said plate portion
being provided on said one side with a circumferential projecting
edge surrounding said plate portion so as to form an annular space
between the outer surface of a base portion of said substantially
cylindrical portion and the inner surface of said circumferential
projecting edge. Said end of said cylindrical body is inserted into
said annular space. Said substantially cylindrical portion is
provided on the outer surface with an annular step portion
corresponding to an inner end of said annular thicker portion in
said end of said cylindrical body. An end portion of said
substantially cylindrical portion of said cover is widened so that
the outer diameter of said end portion is larger than the inner
diameter of said cylindrical body. Said cover is attached to said
end of said cylindrical body by using an inserting means having a
tapered inner surface.
[0019] The substantially cylindrical portion of said cover may be
provided on the outer surface between said base portion and said
annular step portion with an annular projection.
[0020] When the cover is attached to said end of the cylindrical
body by using said inserting means having a tapered inner surface,
the end of the cylindrical body is inserted into said annular space
between the outer surface of said base portion of the substantially
cylindrical portion and the inner surface of the circumferential
projecting edge. Also, the inner end of the annular thicker portion
in the end of the cylindrical body is engaged with the annular step
portion provided on the outer surface of the substantially
cylindrical portion. The annular step portion prevents the cover
from coming out of the cylindrical body. Thus, the cover is firmly
secured to the end of the cylindrical body.
[0021] Even if a third person could manage to remove the cover from
the end of the cylindrical body, he will not be able to reattach
the cover to the end of the cylindrical body because the end
portion of the substantially cylindrical portion of the cover is
widened so that the outer diameter of said end portion is larger
than the inner diameter of the cylindrical body.
[0022] There can be a possibility that a third person removes the
cover from the cylindrical body at a store, puts a foreign matter
into the cylindrical body and attaches the cover again to the end
of the cylindrical body by using an inserting means having a
tapered inner surface prepared in advance. However, it is actually
inconceivable that a person should dare to attach the cover again
to the end of the cylindrical body by using an inserting means
having a tapered inner surface at a conspicuous place such as a
store.
[0023] Thus, the present invention gives safety and freedom from
anxiety to consumers who buy containers containing foods, medical
and pharmaceutical products, etc.
[0024] The annular projection formed between the base portion and
the annular step portion of the substantially cylindrical portion
of the cover is pressed against the annular thicker portion on the
inside of the cylindrical body so as to make the container
airtight.
