"Folding hinge lock for a collapsible container"

The invention relates to a flip-hinge closure for a collapsible container, for example for a tube of toothpaste, consisting of a clamping ring for attaching to the mouth of the container and one with the clamping ring via a folding or film hinge integrated lid.

Well-known closures, also known as "one-hand closure" this type are attached to the outside of the mouth of the ordinary container. Compared to In practice, these closure systems have a relatively small outer diameter of the container and are thus for placing the container overhead or not readily suitable as so-called standing tubes. The lid normally used has a sealing cone that dips into the mouth of the closure. This sealing system is unfavorable, because when closing the product is pushed out of the side of the container mouth and

dirt of the mouth is given a considerable boost. For dispensing two or more at the same time different paste-like substances in the form of a striped strand are the previously known one-handed or hinged locks are not suitable.

However, two or more colored strands can be mixed with others known locking systems are produced. Here is in the mouth of the tube or the container such an externally threaded piece of pipe inserted so that it into the with product to filling space of the tube. V / it is a cloth thereby a passage opening laterally into the pipe section from the inside of the container (compare DE-OS 2 619 936). The known locking system, however, consists of ζ v / ei parts, d. H. the container is separated by means of a To close the screw cap.

The invention is based on the object of a one-piece - that is to say a closure with a non-losable lid - to hold the closure of the same type at the outset, the one as a stand base for the container or tube sufficiently large diameter on v / eist, whose Lid closes the mouth tightly without the risk of product being squeezed out and which can easily be used as' for dispensing a two- or multi-colored strip of a suitable closure body is to be formed. The solution to this problem according to the invention is characterized by one with the one encompassing the mouth Clamping ring integrated, mostly coaxial, fitted into the mouth and to be inserted into it, tubular channel, which on the one hand, when the lid is closed, into a seal located in the latter

tungsringkonus extends into and on the other hand at least as far into the container or its mouth as the clamping ring projects the mouth on the outside includes.

c By the invention is a one-piece closure member has been created in which the advantages of previous one-handed or hinged hinge closures with those previous screw caps are combined without taking on the respective disadvantages. Significant disparity is the one piece of the container mouth, lid and possibly the strip-forming organ existing system. The new closure can therefore be produced in one operation, leave the production machine in the closed state and return to it can be applied to the container or the tube in a further operation. In contrast, were at previously known closures of a similar type in both cases, namely both during manufacture and during assembly of the closure two separate work steps necessary.

The combined effect of the closure mouth that is pulled up into the lid is also particularly favorable the integrated channel and the outer sealing of the mouth by the protruding sealing ring cone on the inside of the lid. Since this seal is the mouth of the breechblock bzi \ r. of the canal from the outside, soiling of the mouth area is largely eliminated.

The integrated tubular channel fitted or inserted into the mouth of the container or tube,

which, in the case of a container designed as a tube, extend at least to the inclined shoulder inside the tube should, not only causes a product-tight and firmly seated hold of the closure member on the container c but also a corrosion protection of the mouth part of the container or the tube. Experience has shown that this area is often not provided with a sufficient protective lacquer layer and therefore not always guaranteed a design of the lock that meets the hygiene requirements. These problems are caused by the Folding hinge lock according to the invention also eliminated.

Eei a closure for simultaneously dispensing at least two different, paste-like substances in the form of a - possibly multi-colored - striped strand of the channel according to xveiterer invention is extended in with product to be filled space of the container or of the tube in, and has at least one of the 'interior of the container on the side opening into the channel extension. In principle, strip-forming organs known per se, such as are known, for example, from DE-AS 1 214 14-1 and DE-OS 2 619 936, can be used in this context. For example, the passages in the duct wall can also be provided at different distances from the end of the duct in order to be able to form strands of three or more colors.

The separate operations for joining tube bodies and mouth part as well as for manufacturing the tube mouth can, however, be omitted if the inventive Closure with or without a streak-forming organ at the same time as it is applied to the so-called Plastic composite tube is produced. While thus previously four operations were required to manufacture the closure member and apply it to the tube body were - namely the separate production of the closure insert on the one hand and the closure lid on the other as well as the separate connection of the closure insert and container on the one hand and the application of the lid on the other hand - two of these manipulations can be performed when applying the teaching according to the invention be summarized.

Pig. 3 one for dispensing a two-tone striped trained lock; and

FIG. 4- a closure similar to that of FIG. 3 but with means for squeezing a three-colored strand.

The closure member according to FIGS. 1 and 2 consists of the clamping ring 2 comprising the container mouth 1, with the
