Abstract

A container (1) with a valve (2) is used to deliver a product in the container (1), in particular a provided with a blowing agent hair care product. The container (1) has a peripheral collar (3) on the head side. A valve plate (4) engages with its edge (5) the collar (3) and enclosing a passage (6). A seal (8) seals the valve disk (4) against the collar (3). In order to prevent the collar (3) from deforming inwardly upon heating of the plastic container (1), a circumferential ring (9) is placed in a space between the collar (3) and the valve (2).

Description

Of the The subject of the application relates to a container with a valve, the z. B. for storing and dispensing hair spray or another Product is suitable for hair care. The valve serves one Application of the product, eg. B. in a manual operation of a Spray head.

Out JP 2002-012277 A is a made of the plastic PET container for a Barber product with a propellant known. A valve plate of the container is reshaped to an upper collar of the container in all directions too stabilize. The container does not have a separate seal between the collar and the valve plate on.

From the DE 199 24 098 A a container according to the preamble of claim 1 is known with a valve for dispensing a product located in the container, wherein the container head side has a circumferential collar. A valve plate engages with its edge of the collar and surrounds a passage for a valve connected to the valve stem. A seal seals the valve disc against the collar.

This known container consists of metal and serves to deliver a liquid product, which Contains propellant. He has the disadvantage that he is relatively heavy, as he in addition to its metallic structure still has a large valve, which extends to the collar.

Would you this container made of plastic, z. B. made of PET (polyethylene terephthalate) finished and provided with a relative to the collar much smaller valve, so would Although you achieve a lower mass, it could be when the heating Container though come to a Kunststoffaufweichung, the upper collar of the container could move inward from the edge of the valve disk, so that in unwanted There, the product could flow out of the container.

Of the Invention is based on the object, a light and safe container according to the generic term of claim 1 to find.

Solved is the Task according to the characterizing Part of claim 1. Thereafter, the container made of plastic, and between the collar and the valve is a ring encircling the valve intended.

Of the proposed containers has the advantage that it is due to the relatively lightweight plastic and a not reaching to the edge valve or valve body relative is light and thus easily held and operated in a simple manner can be, for. B. for dispensing a hair spray. In addition, commercially available valves be used of different diameters. The container is at warming safe with regard to an undesired product outlet. Even with a softening of the plastic, the collar can not deform and thus form a leak. While the ring prevents the collar from deforming towards the interior of the container, The edge of the valve disc limits the collar to the outside. In this way, even when heating the container, for. B. to 80 ° C. for one PET containers, do not form a leak in the area of the collar of the container. It also can not come to a bursting of the valve disk.

is The ring is fixed in position, so it can be heated even when heating container do not fall down, thus losing its backup function. Fixing the ring between the valve, or more precisely, the outer circumference of the Valve body, that contains the valve, and the collar of the container can be done in different ways. So can the Support the ring on a circumferential edge of the valve or collar. there this edge forms a fixing element for the position of the ring. Or the ring is made of an elastic material and is with the seal connected, z. B. in one piece with the seal trained, which brings a mounting advantage. But the ring can also consist of an inelastic material and a Connection to be connected to the seal.

in the The following is the invention with reference to three embodiments described in more detail. It shows in each case a partial vertical section:

1 a container, on whose collar a ring is provided, which is supported on a peripheral edge of a valve;

2 a container in which a ring and a seal are provided in one piece on a valve disc, as well as

3 a container, on whose collar a ring is provided, which is supported on a peripheral edge of the collar.

A container 1 with a valve 2 for dispensing one in the container 1 located, by a Ventilstem 7 dispensable, provided with a blowing agent hair care product has a head-end umlau fenden collar 3 on ( 1 ). A valve plate 4 engages with its edge 5 the collar 3 and encloses a passage 6 for the one with the valve 2 Connected Ventilstem 7 , A seal 8th seals the valve disk 4 opposite the collar 3 from. The container 1 is made of plastic and is therefore relatively light. Between the collar 3 and the valve 2 is one around the valve 2 circumferential ring 9 intended. This is both at the valve 2 as well as on the collar 3 at. He is regarding his strength to the space between the collar 3 and the valve 2 adapted and serves, at high ambient temperature and thereby soft collar 3 this safe above the edge 5 and at the seal 8th to keep. The ring 9 It also prevents the collar 3 inside to the valve 2 could deform. Thus, the ring represents 9 sure the container 1 even with a strong heating of the plastic of the container 1 stays tight. There can be valves 2 or valve body of any diameter can be used. Accordingly, the material thickness of the ring 9 bewählt.

The ring 9 is fixed in position so as not to be able to fall down when the plastic heats up. The ring 9 , which consists of an inelastic material (PET), is on the one hand to a connection 12 (Splice) with the seal 8th connected. On the other hand is a circumferential edge 11 of the valve 2 provided the ring 9 support.

In contrast to this first embodiment, the second embodiment of the ring 9 made of an elastic sealing material and is together with the on the collar 3 resting seal 8th formed in one-piece form so as not to fall down.

In the third embodiment, the ring 9 not with the seal 8th connected. As a fixing element for the ring 9 serves a circumferential edge 13 of the collar 3 on which is the ring 9 supported. The ring 9 consists of inelastic PET.
