Container including a valve
Abstract
A container (1) including a valve (2) serves to discharge a
product located in container (1), particularly a hair care product
provided with a propellant. Container (1) shows a circumferential
sleeve (3) at its top. A valve disk (4) grips under the sleeve (3)
with its skirt (5) and encloses a passage (6). A sealing device (8)
seals the valve disk (4) with respect to the sleeve (3). To prevent
that the sleeve (3) is deformed towards the interior if the
container (1), which is made of plastic, heats up, a
circumferential ring (9) is put into the gap between the sleeve (3)
and the valve (2).

Description
[0001] Object of the present application is a container including a
valve that is suitable, for example, for storing and discharge of
hair spray or another hair care product. The valve serves to apply
the product, e.g. for a manual operation of the spray head.
[0002] A container for a hair salon product is known from JP
2002-012277 A that is manufactured from PET plastic and includes a
propellant. A valve disk of the container is reformed to stabilize
an upper sleeve of the container in all directions. The container
does not show a separate sealing device between the sleeve and the
valve disk.
[0003] A container pursuant to the generic term of claim 1 is known
from DE 199 24 098 A including a valve for discharge of a product
located in a container, whereas the container shows a surrounding
sleeve at the top. A valve disk grips under the sleeve with its
skirt and encloses a passage for a valve stem, which is connected
to the valve. A sealing device seals the valve disk with respect to
the sleeve.
[0004] This known container consists of metal and serves to
discharge a liquid product, which contains a propellant. It has the
disadvantage that it is relatively heavy because, in addition to
its metallic structure, it shows a large valve that reaches up to
the sleeve.
[0005] If this container were made of PET, for example,
(polyethylene terephthalate) and were provided with a significantly
smaller valve with respect to the sleeve, a decreased mass could be
achieved, the plastic could, however, soften during warming of the
container, whereas the upper sleeve of the container could separate
from the skirt of the valve disk so that the product could flow
from the container at that location in an undesired way.
[0006] Object of the present invention is to find a light and
secure container pursuant to the generic term of claim 1.
[0007] The object is achieved according to the characteristic part
of claim 1. According to claim 1 the container is made of plastic
and a circumferential ring around the valve is provided between the
sleeve and the valve.
[0008] The proposed container has the advantage that it is
relatively light due to the relatively light plastic, and a valve
or a valve body that does not reach up to the skirt and thus can be
easily held and operated manually, for example for output of a
hairspray. Additionally, commercially available valves of different
pressure gauges can be used. The container is secure regarding
undesired product discharge when heated up. Even during softening
of the plastic the sleeve can not be deformed and thus form a
leakage. While the ring prevents that the sleeve deforms towards
the interior of the container, the edge of the valve disk limits
the sleeve towards the outside. In this way no leakage can build up
in the area of the sleeve, even when the container warms up to, for
example, 176.degree. F. (80.degree. C.) for a PET container. The
valve disk can not crack off, either.
[0009] If the ring is fixated in its position it can not fall down
and lose its securing function, even when the container heats up.
The fixation of the ring between the valve, or, more accurately
stated, the outer circumference of the valve body that contains the
valve and the sleeve of the container can be implemented in
different ways. The ring can, for example, be propped up by a
circumferential edge of the valve or the sleeve. This edge forms a
fixation element for the position of the ring. Or the ring consists
of an elastic material and is connected with the sealing device,
e.g. in one part together with the seal, which provides mounting
advantages. The ring can also, however, consist of a non-elastic
material and be connected via a connection to the sealing
device.
[0010] Three exemplary embodiments of the invention with reference
to drawings follow below. A respective partial vertical sectional
cut shows in
[0011] FIG. 1 a container that provides a ring at its sleeve, the
ring being propped up by a circumferential edge of a valve;
[0012] FIG. 2 a container that provides a ring and a sealing device
in one part on a valve disk, and
[0013] FIG. 3 a container that provides a ring at its sleeve that
is propped up by a circumferential edge of the sleeve.
[0014] A container 1 including a valve 2 for discharge of a hair
care product, which is situated in container 1 and can be released
through a valve stem 7 and is provided with a propellant, shows a
circumferential sleeve 3 at the top (FIG. 1). A valve disk 4 grips
under the sleeve 3 with its skirt 5 and encloses a passage 6 for a
valve stem 7, which is connected to the valve 2. A sealing device 8
seals the valve disk 4 with respect to the sleeve 3. The container
1 is made of plastic and is therefore relatively light. A ring 9
circumscribing the valve 2 is provided between the sleeve 3 and the
valve 2. It contacts the valve 2 as well as the sleeve 3. Regarding
its strength it is fitted into the gap between the sleeve 3 and the
valve 2 and serves to keep the sleeve 3 securely above the skirt 5
and next to sealing device 8 if the sleeve 3 softened due to high
ambient temperature. Ring 9 also prevents that sleeve 3 could
deform towards the interior with respect to valve 2. In this way
ring 9 ensures that container 1 remains tightly sealed even during
intense heating of the plastic of container 1. Valves 2 or valve
bodies of any diameter can be used. The material strength of ring 9
is chosen in a respective manner.
[0015] Ring 9 is fixated in its position in order not to fall down
during a heating of the plastic. Ring 9, which is made of a
non-elastic material (PET), is connected via a connection 12 (glue
area) with the sealing device 8, for one thing. Furthermore, a
circumferential edge 11 of valve 2 is provided to prop up ring
9.
[0016] For the second exemplary embodiment of the present
invention--in contrast to the first one--the ring 9 consists of an
elastic sealing material and is made out of one form together with
the sealing device 8 that lays on top of sleeve 3 in order not to
fall down.
[0017] Ring 9 is not connected to sealing device 8 in the third
exemplary embodiment of the present invention. A circumferential
edge 13 of sleeve 3 serves as fixating element for ring 9, with
sleeve 3 being propped up by ring 9. Ring 9 is made of non-elastic
PET. [0018] 1 Container [0019] 2 Valve [0020] 3 Sleeve [0021] 4

[0031] All documents cited in the Detailed Description of the
Invention are, in relevant part, incorporated herein by reference;
the citation of any document is not to be construed as an admission
that it is prior art with respect to the present invention. To the
extent that any meaning or definition of a term in this written
document conflicts with any meaning or definition of the term in a
document incorporated by reference, the meaning or definition
assigned to the term in this written document shall govern.
[0032] While particular embodiments of the present invention have
been illustrated and described, it would be obvious to those
skilled in the art that various other changes and modifications can
be made without departing from the spirit and scope of the
invention. It is therefore intended to cover in the appended claims
all such changes and modifications that are within the scope of
this invention.
