Definitions

• Squeezeable container for media of pasty or creamy consistency and high-viscous fluids.
• the invention relates to a squeezeable container of thinwalled extruded plastic for media of pasty or creamy consistency and high-viscous fluids, with a discharge opening, or a potential discharge opening through which the content can be squeezed out.
• a potential discharge opening is here to be understood a portion of the container wall uhere an opening is prepared or where a suitable opening can be produced easily, e.g. by cutting off part of the container.
• Squeezeable containers are known with discharge openings in the shape of a neck or a stub to be closed by means of a plug or a cap, with a threaded stub to be closed with a threaded cap, with an elastic neck with a slit to be opened by bending the neck and which closes by the neck straightening out itself by elastic force, as well as types with a beak which closes by a lio closure, a.o.
• a common feature of these known discharge openings is that they have the closing device placed outside the container itself.
• Containers with a potential discharge opening are known as well, the actual opening being produced by cutting off a strip or a corner of the container.
• a common feature of these containers is that the discharge opening is not recloseable after once having been opened.
• containers which can be opened at one end of the container, and which can be closed by means of inner linear protrusions which, by being pressed together, engage with one another.
• a common feature of these containers is that they are opened by the container ualls being pulled from one another by which the linear protrusions disengage, and that the opening extends from one side of the container to the other, which makes a controlled dis charge of the content difficult, and that the container is not totally sealed before use.
• a squeezeable container without an outside closing device, and which can be produced solely from extruded plastic material. It can also be desirable that the container is totally sealed along all edges before use in order to prevent the content from drying out. It is furthermore desirable that the container has such a discharge opening that a controlled discharge of the content can be effected, and that the discharge opening can be reclosed.
• the squeezeable container according to the invention satisfies these uishes, as it is characterized by the inside of the container ualls having parallel linear protrusions with such a profile that protrusions on one portion of the container wall can engage in the protrusions of an opposite portion of the container wall and thereby maintain these portions in engagement with each other, and by the discharge opening or the potential discharge opening betueen two opposite container wall portions adjoining the linear protrusions being slit-shaped in such a way that the opening can remain closed when the protrusions are pressed together.
• the basis of the invention are containers with internal protrusions with profiles suitable for engagement in each other, mentioned in U.S. patent no. 3.160.323.
• the linear protrusions are solely intended for keeping the container walls pressed together after squeezing out the content so that the container walls are prevented from springing back and causing a vacuum in the container, and they are n o t used for a subsequent closing of the discharge opening.
• the container can be produced from tubing, tube, or strip of ex truded, thin-walled plastic material, and that it does not need an outside or specially inserted closure.
• Other advantages according to the invention are that the container can be totally sealed before use and that a controlled discharge of the content can be effected.
• a commonly used execution of the squeezeable container according to the invention will be made with a pptential discharge opening, meaning that before use the container will be sealed along all edges and that it is made ready for use by cutting off a strip or a corner.
• the container has a discharge channel
• the invention can therefore apply to the type of container which is provided by one edge with a discharge channel, which is formed betueen the edge and a partial seam close to this between tuo opposite container wall portions.
• a container can, according to the invention, be formed in such a way that the linear protrusions transverse the discharge channel so that a pressure applied on the outside of the container walls at the discharge channel causes the protrusions to engage into each other and close the channel.
• the discharge opening is placed in the outer end of the channel and will normally, as is the case with the containers knoun, only be potential so that the container is made ready for use by cutting off the outermost part of the channel ualls.
• a container according to the invention can be reclosed by applying a pressure on the outside of the channel and be reopened by applying a pressure on the content of the container, while at the same time a pressure is applied on the edge of the container opposite the channel, parallel to the linear protrusions.
• the container may also be appropriate to provide the container with a discharge funnel as an alternative to the discharge channel.
• the invention can also be applicable in a container of the kind made with a discharge funnel narrowing touards the discharge opening, formed by a local sealed seam placed betueen tuo edges of the container, sealing tuo opposite container wall portions.
• a container may, according to the invention, be formed in such a way that the local sealed seam extends in a straight line form one end of the edge of one side, at an angle with this, to an opoosite edge, and furthermore that the linear protrusions extend across the discharge funnel and are longitudinally parallel to the discharge opening.
• a pressure applied on the outside of the container walls, at; the narrow part of the discharge funnel, causes the protrusions to engage and close the funnel.
• Reopening is effected by applying a pressure on the content of the container and simultaneously applying pressure on the edge of the container at the funnel and parallel to the linear protrusions.
• the discharge opening is placed at the outermost end of the discharge funnel and is usually, as is the case with the containers known, only potential, thus the container is made ready for use by cutting off a strip of the container walls.
• Another variant of the container with a discharge funnel according to the invention may have the discharge funnel formed by a local U-shaped sealed seam where the sides of the angle extend to two of the container edges, at angles with these.
• Containers with other types of seamed opposite container wall portions may also be made with the same purpose, i.e. to lead the content towards the discharge opening and ensure that this can be reclosed after squeezing together the linear protrusions of a limited part of the container adjoining the discharge opening.
