Description

field of use

The invention relates to a device according to the preamble of claim 1.

The field of application relates to a device for a disposable cup with disposable cup lid, in particular a disposable cup with disposable cup cover for "coffee to go" (coffee-to-go) from which the coffee can be directly fed with attached disposable cup lid ,

State of the art

It is known that the disposable cup with disposable cup lid is designed in such a way that the disposable cup lid is attached externally of the disposable cup. The cup lid edge is slipped over the edge of the disposable cup so that the integrated groove of the cup lid edge receives the crimp edge of the cup edge.

This spring-groove system is thus the sole fastening technique, wherein the contact surface of the tongue and groove system is the sealing surface.

In a disposable cardboard drinking cup, there is a continuous vertical overlapping seam which incorporates leakage in the sealing area between the disposable cup and the disposable cup lid at the location of the seam in the region of the upper flange edge.

The drinking opening is integrated in the disposable cup lid. The drinking opening is located above the edge of the disposable cup. The drink is directly toasted with the disposable cup lid attached, either by drinking with adjacent lips on the disposable cup lid which passes through the disposable cup lid.

The disposable cup lid is used in particular as a splash guard to prevent leakage of the beverage, especially during transport of the disposable cup. The most common mode of transport is carrying the disposable cup while running or in a moving motor vehicle.

The drinking from the disposable cup with attached disposable cup lid takes place especially during running or driving.

The drinking cup with cup lid is also on the market as a reusable product state of the art. In addition to the pushed-on cup lid, today there are a variety of designs in the reusable cup - due to the use of higher quality material and more generous material consumption and the use of additional sealing material on the edge of the cup lid - a variety of designs. The most common construction for the attachment is a screw cap, followed by the screwed-on cup lid.

In addition to the outer cup lid, it is already state of the art with the reusable cup - due to the greater scope of the construction of the sealing system - to perform the cup lid as a push-in lid or in a mixed form of put-on and push-in lid.

The disposable beverage can with permanently mounted can lid has an inner can lid wherein the edge of the can lid is performed on the upper edge of the can beaker in the form of an outer flanged edge.

Disadvantages of the prior art

Disadvantage of the prior art is that when drinking from the disposable cup, in case of leakage between disposable cup and disposable cup lid, leakage may occur. Since the lips abut above the sealing surface, a leakage leads to a contamination of the underlying objects with the drink, especially the worn clothes.

The leakage between the disposable cup and the disposable cup lid occurs when the folded edge of the disposable cup does not sufficiently lock into the groove of the disposable cup lid. Since no clear visual inspection is possible, is often only by pressing the disposable cup lid a hope that the disposable cup lid is properly placed on the disposable cup.

An always-existing weak point in a disposable cup with production-related overlap of the connecting seam is the built-in leakage in the sealing area. If the drinking opening lies in the peripheral region of the connecting seam, a leak during drinking is inevitable.

Another reason is the possible tearing of the edge of the disposable cup lid. Due to the crack, there is no longer sufficient hoop stress to ensure contact of the sealing surface. In addition, there is the disadvantage that the contact surface of the seal in the radial direction is very small, so that the smallest interruptions in the circumferential direction of the sealing surface immediately install a leakage in the radial direction.

The staining with the drink can lead to damage to the underlying objects, especially objects that are equipped with electronic function - such as a laptop, or in particular objects that are equipped with high-quality surface - such as an expensive seating.

Object of the invention

The object of the invention is to provide a device for the disposable cup with disposable cup lid, which provides increased protection against contamination or damage to objects by the drink while drinking from the disposable cup with attached disposable cup lid. Furthermore, it is an object of the invention to carry out this device with less material consumption for the disposable cup lid.

Solution of the posting

This object is achieved by a device having the features of claim 1.

Advantages of the invention

The device has the advantage that, while drinking from a disposable cup with a disposable cup lid, a potential leak between disposable cup and disposable cup lid does not result in staining or damage to underlying objects; as it is partly standard today is the reusable cup with reusable cup lid. This advantage, which provides increased protection against object staining or damage, provides a unique, improved safety protection for the disposable cup with disposable cup lid.

This has the particular advantage that while wearing a disposable cup with disposable cup lid worn clothing is less risky stained, which is an important event - especially festive affairs or meetings - worn and can not be changed for the important event.

This has the particular advantage that while drinking from a disposable cup with disposable cup lids electronic devices are better protected against damage from liquids that you drink from the disposable cup with disposable cup lid, especially when drinking while working on a laptop.

This has the particular advantage that high-quality seats or car seats are better protected against damage from drinks that you drink from the disposable cup with disposable cup lid.

The advantage of the invention is that the device can be carried out with little or no change in the construction of the disposable drinking cup. And the modified construction of the disposable cup lid can be carried out without additional expense of design time. Furthermore, the change in the disposable cup lid results in a construction of the disposable cup lid which consumes less material and thus spares costs and environmental resources.

Another advantage of the invention is that the cost of development for the construction of the disposable cup and the disposable cup lid and the manufacturing and packaging process is immaterial.

The device of the invention is easy to communicate in use and task in the marketplace.

Advantage of the invention is that it opens up a variety of design and marketing options in addition to the unique feature of the device.
