Abstract:
The process relates to the production of a product consisting of a substrate to which an adhesive with long-term effect and a protective band are attached to permit use of the adhesive to be deferred. The process is characterized by the use of a substrate whose surface to which the adhesive is attached may present irregularities. The adhesive is heated to a temperature at which is becomes paste-like and almost liquid, and is brought to an opening situated above a plane surface on which the substrate has been placed. The adhesive is then caused to flow simultaneously with a relative movement between the substrate and the opening. This results in the adhesive being deposited on the substrate as a strand that is preferably continuous. The temperature of the adhesive is then lowered in order to increase its viscosity until it becomes paste-like to the point of turning solid. Pressure is thereafter applied to the paste, like adhesive, preferably with the imposition of a protective strip, in order to cause spreading of and to cover the strand along its full length. Finally, the resultant product may be cut to produce a substrate having an adhesive strip thereon and a detachable protection band covering the adhesive strip.
Abstract:
This relates to a machine for assembling end units with container bodies. The container bodies have cylindrical open upper ends over which a cylindrical lower portion of an end unit or dome is telescoped with the overlapping portions being adhesively bonded together. The machine receives the end units serially and by way of a Ferris wheel type conveyor moves the end units first to an adhesive applicator where a band of adhesive is applied to the interior of each end unit, after which each end unit is then telescoped over and pressed into position relative to an associated body. The operation of the machine is continuous.
Abstract:
A nozzle for applying an air-curable adhesive to sheets of paper normally is located in a storage position with the end of the nozzle inserted into a liquid in a sump. This prevents adhesive material in the end of the nozzle from drying out or caking and thereby clogging the end of the nozzle. When the nozzle is to be used for applying adhesive, the nozzle is lifted out of the sump, the sump is moved, and the nozzle is then moved into an operating position for applying the adhesive. Also disclosed is apparatus for automatically returning the nozzle to its storage position with the end of the nozzle in the sump at the end of a cycle of operation, or when normal operation stops because of a power failure, for example.

An adhesive applicator for applying an air-curable adhesive to sheets of paper has a nozzle that normally is located in a storage position with the end of the nozzle inserted into a liquid in a sump. This prevents adhesive material in the end of the nozzle from drying out or caking and thereby clogging the end of the nozzle. When the nozzle is to be used for applying adhesive, the nozzle is lifted out of the sump, the sump is pivoted away from the nozzle, and the nozzle is then moved into an operating position for applying the adhesive.
Abstract:
A secondary container packaging material for use in six pack can wraps, six pack bottle carriers, twelve pack carriers, etc., comprising a composite of a paper material laminated to a plastic film. The plastic film provides tear resistance to the composite, so that paper material may be used which has a tear resistance less than that of other secondary packaging paper materials. The reduced tear resistance allows the use of paper having a lower caliper, basis weight, and, therefore, cost than conventional secondary container packaging material. Natural kraft paper and recycled paper of 12-16 point caliper are preferred for use with the present composite. The plastic film may be 0.25-2 mils thick and is preferably formed of polyethylene terpthalate, polyethylene, polyvinylchloride, polypropylene, or cellophane. The preferred films are transparent and permit reverse printing on their inner surface to provide abrasion resistant decoration visible through the film. Adhesives are used to bond the film to the paper and are selected to be compatible with the film used. The film may be metallized to produce a foil effect or may be strengthened by radiation treatment.
Abstract:
An improved apparatus for supplying fluid such as liquid lubricant or glue to a partially assembled container during assembly thereof. The apparatus employs a flexible tube pump driven by a reciprocatable frame or structure on a container assembling machine via a lever arm acting through a one-way clutch assembly to thereby rotate the tube pump rotor in successive increments of rotation of less than 360.degree.. In one embodiment, apparatus is disclosed in which a liquid dispensing head is reciprocated into and out of engagement with a partially assembled container by means of a reciprocatable frame and actuation of the flexible tube pump is obtained after such engagement in response to additional movement of the frame relative to the liquid dispensing head. In another embodiment, means are disclosed for preventing dispensing of liquid when a container will not be present at the liquid dispensing station.
Abstract:
A method of creating a package with reclosable resealable flaps. The package is defined by a blank formed by die cutting a continuous web or sheet of material after ink and a release coating have been applied to one side of the web but on different areas. The blank, when folded, provides a structure with a rectangular cross-section having four planar sides, each side with extending flaps. A package is formed by closing and securing the flaps on the bottom end of the structure using a permanent adhesive. The package is then filled with product. One top outer flap can have a release coating applied to an area which will be engaged by the opposite flap when closed. This release coating, in combination with a repositionable adhesive, will cause the opposed flaps to releasably adhere one another to secure and seal the top opening. Repositionable adhesive can also be applied, either to the release coating itself, or to the surface opposite the release coating to the seal. When the top flaps are initially closed during the packaging process, an area of permanent adhesive is placed on at least one of the flaps to secure the flaps to each other when closed.
Abstract:
In the manufacture of packets on which folding flaps or other packaging parts are connected to one another by glue, the latter is applied to the blank (10) of the packet by glue nozzles 16. When there is a temporary breakdown, the gluing unit (15) is moved into a waiting position remote from the rotary folding unit (11) and held here in an operating position in a phased manner by the release of glue portions.
Abstract:
The present invention provides a method of forming a pre-wrapped gift package which appears to have been hand wrapped. The method includes forming a sheet of box construction material with decorative paper affixed thereto into a flattened box tube by joining ends thereof. The box construction material is properly creased and provided with flaps so that a consumer may erect the flattened box tube into an open box so that the end flaps form ends of the box and the decorative paper forms a pair of paper flaps which may be overlapped and secured. A volume sizer is provided in the form of creased box construction material which, when erected, provides an illustration of the volume made available when the pre-wrapped gift box is erected. Box loading devices, particularly useful for shirt box sized packages, are provided in the form of inner sleeves and mechanical devices into which the gift is placed before insertion into the pre-wrapped gift box. Side loading, top opening configurations provide additional support for the pre-wrapped appearance. Gathering triangles are provided between flaps to aid in the closing of the flaps to form the pre-wrapped gift package.
