Device for connecting sheaths together by applying adhesive internally, a corresponding roll of adhesive, and a corresponding method of connection
The invention provides a device for connecting together two flat tubular sheaths, the device including: a blocker (22a, 22b, 22c, 22d) for blocking one end of a first sheath, the blocker having means for opening an end of the first sheath; an adhesive-applicator system for applying adhesive to the inside of the open end of the sheath; the blocker being arranged to authorize closure of the end of the first sheath, once adhesive has been applied thereto, on an end of the second sheath. The invention also provides a corresponding roll of adhesive and a corresponding connection method.
Composite Label and Method of Making
A method for making labels comprising providing a plastic substrate layer and a paper substrate layer. The paper substrate layer comprises a printed display information sheet, wherein the printed display information sheet comprises a plurality of display information tags arranged in an array. The plastic substrate layer is coupled to each of the rows of display information tags within a first portion of the display information tags to form a composite substrate row. A first line of perforations is cut into a width of the composite substrate at one or more first spaced intervals, a length of the first spaced intervals being defined by a length of the display information tags. A a second line of perforations is cut into a width of the composite substrate at one or more second spaced intervals, a length of the second spaced intervals being defined by a height of the display information tags.
PET Bottle for Efficient Recycling Comprising an Easily Removable Label and a Cap without a Retainer Ring
The present invention relates to a PET bottle which increases recycling rate of PET bottles, wherein the PET bottle comprises a label that assembles the cap 20 without a retainer ring 21 on to the body 10 of the PET bottle, seals from the top of the cap 20 to the upper portion of the body 10 with the one continuous label and safety seal film 50, and has vertical parallel perforated lines 51 on one portion of the sealed label and safety seal film 50. A flap 52 extends from the end of the upper end of the perforated lines 51 to assist with tearing the label. The sealed label and safety seal film 50 covers the upper portion of the body 10 in shape of an inverted funnel, such that when it is torn along the perforated lines 51, the film 50 will be separated naturally from the bottle.

Polyester label and packaging container
The inventive label is prepared from a polyester with an intrinsic viscosity of 0.58 dl/g or more. The label has a base film with a thickness of 8-30 m and a difference in specific heat capacity Cp between temperatures lower and higher than Tg of 0.2 J/(g.Math. C.) or more. The label has a tensile elongation at break of 5% or more in both a main shrinkage direction and an orthogonal direction. A difference between the absorbancy ratio (absorbancy at 1340 cm.sup.1/absorbancy at 1410 cm.sup.1) in the main shrinkage direction of the label and the absorbancy ratio in the direction orthogonal to the main shrinkage direction of the label is 0.2 or more. The label has a difference between a maximum value and a minimum value of a length in a vertical direction of the label of 3 mm or less.
SHRINK WRAP LABELS FOR SHAPED ARTICLES
Methods for applying high shrink wrap labels to a shaped article are disclosed. The leading edge of the label is bonded to the article. A seaming agent is applied, and the label is wrapped around the article. The seaming agent is then exposed to radiation to cure the seaming agent, and the label is then exposed to heat to cause heat-shrinking. The label is made of a film with at least one external layer that has a Hildebrand solubility parameter. The seaming agent includes a component having a Hildebrand solubility parameter that is within 2.2 MPa.sup.1/2 or within 4.4 calories.sup.1/2.Math.cm.sup.3/2 of the Hildebrand solubility parameter of the external layer of the film. The seaming agent also has a viscosity of at least 1 centipoise and less than 1000 centipoise when measured at any temperature between ambient temperature and 60 C. Articles including such affixed high shrink wrap labels are also disclosed.
METHOD OF APPLYING A LABEL TO A CONTAINER AND A CONTAINER PRODUCED BY SAID METHOD
A method for applying a label to a container particularly suited for applying a polypropylene label to a polypropylene cup as it is moulded. The resultant container is made of a single type of plastic allowing it to be easily recycled. The mould used to produce the container has been designed to hold a label in place and stretch a portion of the label so it stays in place before injecting the plastic to form the container.
HEAT-SHRINKABLE FILM AND HEAT-SHRINKABLE LABEL
What is provided is a heat-shrinkable film and a heat-shrinkable label that, when applied to a container in which the difference between the diameter of the body portion and the diameter of the mouth portion is large, sufficiently shrink in the mouth portion and do not easily allow the generation of a wrinkle or a sink mark in the mouth portion. The heat-shrinkable film contains polyester, a dicarboxylic acid component that constitutes the polyester contains 95 mol % or more of terephthalic acid, and a diol component that constitutes the polyester contains 50 mol % or more of ethylene glycol and 15 mol % or more of cyclohexanedimethanol. The shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 70 C. for 30 seconds is 20% or less, the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 80 C. for 30 seconds is 45% to 65%, and the shrinkage rate in the primary shrinkage direction when the heat-shrinkable film is immersed in hot water at 98 C. for 30 seconds is 65% or more.
Method and apparatus for producing three-dimensional decoration piece made of thermoplastic synthetic resin
A method and an apparatus for producing a three-dimensional decoration piece that does not damage the tacky bonding or adhesion strength of the lower layer material of the decoration piece. The method includes putting an upper layer material on a first table operating as cathode; lowering an upper mold operating as anode onto the first table, emitting a high frequency wave for dielectric heating; stopping the high frequency dielectric heating; moving a second table carrying a lower layer material having a tacky bonding property to below the upper mold; and lowering said upper mold onto the second table. In the apparatus, the second table or the lower mold is provided on the top surface thereof with recessed sections that are transversally and inwardly separated from a position where an edge of the first machining means contacts, by 0.2 mm to 1 mm; and a cushion member being arranged in the respective recessed sections.
