Problems solved by technology

Attempting to insert the preform is likely to interfere with the preform when placing the label, especially when placing the label on each of the two mold pieces that are in the open position at the same time

Embodiment Construction

[0031] Accordingly, in carrying out the above objects, the present invention provides a system and method for in-mold labeling which do not suffer from the disadvantages / problems of prior in-mold labeling systems and methods as described above.

[0032] According to a preferred embodiment of the present invention, the in-mold labeling process is carried out by a two-stage blow molding process, compared to the conventional method of a single-stage blow molding process. In a two-stage blow molding process, preforms are prepared or supplied separately and fed into a blow molding machine. Typically, in a two-stage process, the preforms are manufactured individually and, when inserted into the mold, are in solid rather than molten or semi-molten form.

[0033] In another preferred embodiment, polyethylene terephthalate (PET) is used to manufacture the container using a two-stage blow molding technique for in-mold labelling. In addition to being more environmentally friendly compar...

Abstract

The present invention relates to a system and method for in-mould labelling of articles. In particular, the present invention pertains to a system and method for in-mould labelling of multiple labels on two or more adjacent surfaces of a container (102) with polygonal cross-section. The present invention provides a combination of mould formation coupled with a design for magazine and robotic arm (606) to enable simultaneous application of multiple in-mould labels across multiple surfaces of a polygonal container (102) with minimal dead space between the labels. Simultaneous application of multiple labels and the preform inside the mould opening as per the present invention reduces cycle time and increases output efficiency.

Description

[0001] This application claims the benefit of Indian Provisional Application No. 201911004187 entitled "A System and Method for InmouldLabelling", filed 2 February 2019, the entire content of which is hereby incorporated by reference. Technical field: [0002] The present invention relates to a system and method for in-mold labeling of articles. Background technique: [0003] Most consumable products and foods (whether solid or liquid) are stored in food-grade liquid-tight containers, usually made of polymeric materials. Generally, these containers are formed by thermoforming, blow molding or injection molding of multilayer polymeric materials, usually consisting of layers of polypropylene, polyethylene or PET, to obtain a rigid container body. Due to such uses of polymeric containers, it becomes crucial to apply labels which not only can be applied to these containers but also extend the use of the containers. Labels may include information about the product, ingredients, ...
