Disposable multi-cup type sealing structure

Abstract

The invention relates to a disposable cup, particularly a disposable cup and a packaging thereof overlapped by a plurality of cups with food. The disposable cup consists of a disposable cup type container overlapped by two or more cups, heat-seal materials or a lid is used to cover on top of the most top cup to seal the cup. The disposable cup is characterized in that a cup sleeve is sleeved onto external wall of a cup body, an external layer of the cup sleeve is stuck with paper, plastic or aluminum foil packaging materials, and dashed indentation line or guide tearing strip on the materials is arranged between two adjacent cup sleeves. According to the disposable multi-cup type seal structure, multi-cup type sealing technique becomes more hygienic, practical and easy to operate, two adjacent cup bodies are sealed, and an action of fetching lower cup body does not affect sealing effect of upper cup body.

Description

technical field [0001] The invention relates to a disposable cup, in particular to a plurality of nested disposable cups containing food and their packaging. Background technique [0002] Disposable cups have been generally accepted as daily drinking containers. At present, the packaging method of disposable cups or disposable bowls combined with food has also been widely promoted, such as beverage cups containing solid milk tea powder packages and instant noodles in buckets that are common on the market, and disposable cups and bowls can also be used to package solid pharmaceutical powders Granules, concentrated liquids in bags, tea leaves in bags, solid beverage powder packets, soup stock in bags. But this kind of packaging method of packing the same food with a cup, because the volume of the cup is greater than the volume of the contained food, has caused the waste of the cup packaging space, thereby increasing the product storage and transportation costs. In order to r...

Problems solved by technology

However, there are three defects in the patent (CN2362776), which makes it difficult to convert it into a product with market competitiveness, which leads to the fact that the packaging product it provides has not appeared on the market until now.

First of all, since the heat-shrinkable film sleeve is sealed on the rim of the cup, and the rim of the cup is the part that directly contacts with the lips when people drink water, this makes the rim of the cup have a sanitary risk of contamination.

Secondly, in the process of producing this packaging product, when the volume of food placed at the bottom of the cup is larger than the storage space formed by the natural nesting of the two cups, due to the lack of a fixed spacing device between the two nested cups, the cup The size of the space between the two cups cannot be controlled during nesting, so the size of the storage space formed by the stacking of the two cups cannot be controlled. As a result, the nesting position of the cups cannot be fixed when food is placed in the nesting cups, which increases the need for nesting. The difficulty of sealing the heat shrinkable sleeve

Finally, the patent (CN2362776) does not disclose the technological process of sealing the heat-shrinkable film sleeve on the rim of the cup, and only indirectly infers the possibility of realizing this packaging structure. The reason for the inference is that "in some existing packaging materials There have been applications, such as the external packaging of commercially available audio or video tape boxes with strong pull strips", but the shape of the audio or video tape boxes in the inferred reason is a cuboid, and the packaging machine is a transparent film packaging machine or a three-dimensional packaging machine. The existing technology of this machine cannot realize heat-shrinkable film sleeve packaging on the cylinder with convex edges formed by nested cups, so the reason for the above inference is not valid. The technology of the sleeve and the precision to be achieved by this technology are currently difficult to achieve in the field of disposable cup packaging production, or the cost and rejection rate of this technology are relatively high. Therefore, technicians in the field of disposable cup packaging production use conventional experiments or The analysis method is not enough to realize the sleeve packaging structure proposed by the patent (CN2362776)
