Disclosed is a bottle for containing liquid content including a body portion, at least part or the entire portion of an upper portion of which is provided with a plurality of guides which protrudes inward from an inside surface thereof and is in a spiral pattern so that the liquid content can be guided towards an opening of a neck portion of the bottle while spirally revolving inside the bottle.

Provided is a synthetic resin container that includes a container main body molded into a predetermined container shape and a covering layer laminated on an outer peripheral surface side of the container main body. A label is mounted on a container body portion. The container main body is provided with a step portion formed by raising or denting a peripheral surface that extends continuously or discontinuously along a predetermined direction and the covering layer is provided with, continuously or discontinuously along the step portion, a linear thin portion that is linearly thinner than a surrounding area. At least part of the label is adhered to a portion of the covering layer adjacent to the linear thin portion.

A lug closure includes a central top panel, an annular channel outboard of the top panel, a downwardly extending skirt outboard of the channel, the skirt terminating at an inward curl that defines a curl height, and lugs formed in the curl. Each one of the lugs includes a body that extends radially inwardly from the skirt. The body includes a leading edge that merges into a leading portion of the curl. The leading edge tapers in thickness from the curl height to a minimum lug thickness and forms a leading edge vertical taper angle from horizontal between 6 and 15 degrees. A trailing edge merges into a trailing portion of the curl and the trailing edge tapers in thickness from the curl height to the minimum lug thickness.

A hollow body includes a wall which at least partially surrounds an interior volume of the hollow body. The wall comprises a layer of glass comprising a first glass composition, comprises a base surface, and has a wall surface. The wall surface comprises at least one surface region, in which the base surface is at least partially superimposed by at least one elevated region, and at least one contact region, which extends along a contact range of a height of the hollow body. The at least one elevated region comprises a further glass composition. An exterior diameter of the hollow body has a maximum throughout the contact range. The at least one surface region is at least partially positioned in the at least one contact region.

Preform assembly for blow moulding a container, comprising at least a first and a second perform, wherein the first perform is positioned inside the second perform before blow moulding the performs into the container, wherein each perform has a body forming portion having a wall thickness of less than about 8 millimetres, preferably less than about 6 mm.

Provided is a multilayer container including: a polyester layer containing a polyester resin (X); and a polyamide layer containing a polyamide resin (Y) and a yellowing inhibitor (A). The content of the polyamide resin (Y) is from 0.05 to 7.0 mass % relative to a total amount of all polyamide layers and all polyester layers, and the content of the yellowing inhibitor (A) is from 1 to 30 ppm relative to the total amount of all polyamide layers and all polyester layers. Also provided are a method for manufacturing the multilayer container, and a method for manufacturing a recycled polyester, the method thereof including a step of recovering polyester from the multilayer container.

A preform for molding a dual container, in which an inner preform is inserted into an outer preform in a state in which a mouth portion of the inner preform is fitted into a mouth portion of an outer preform, the inner preform is formed of a crystalline resin, a crystallized region is provided in at least a portion of the inner preform, the crystallized region having a degree of crystallization greater than that of the other portion, the portion of the inner preform adjacent to the mouth portion from below the mouth portion and located below the outside air introduction hole, a step portion facing upward and a rib extending upward from the step portion are formed on an inner circumferential surface of the inner preform, and at least a part of the rib is adjacent to the crystallized region from above the crystallized region.

An assembled preform (1) is provided for the making of a blown container, comprising a first external preform body (10) which comprises a neck part (2) which has an external region (4) which includes a threaded region (5) and an internal surface (3), and a second internal preform (11) which is suitable to be completely contained within said first external preform body (10), said second internal preform (11) having a neck region (12) suitable to cooperate with said neck internal surface (3) of said first external preform (10), the preform being characterized in that said neck region (12) of said second internal preform (11) comprises locking means (13,14) integrally obtained on the material of said second preform (11) and suitable for cooperating by blocked interference with said internal region (3) of the neck part (2) of said external preform (10) when said second internal preform (11) is inserted in said first external preform (10).

First, a composite preform 70 including a preform 10a and a plastic member 40a in close contact with the outer surface of the preform 10a is made by preparing the preform 10a made of plastic material and arranging the plastic member 40a to surround the outer surface of the preform 10a. Subsequently, the composite preform 70 is heated and inserted in a blow molding die 50 and undergoes blow molding in the blow molding die 50, by which the preform 10a and the plastic member 40a of the composite preform 70 are inflated integrally and a composite container 10A is obtained.

A container includes a capitula to put contents into and out from the container, an inside container main body, in which a portion to accommodate the contents is formed, and an outside container main body, which is formed on an outer periphery side of the inside container main body, and surrounds the inside container main body. The inside container main body and the outside container main body are integrated at the capitula. A first side peripheral wall of the inside container main body and a second side peripheral wall of the outside container main body are attached to each other and are formed as a double accumulating portion at least at a portion of the first side peripheral wall. A lower end of the second side peripheral wall includes an extended foot portion that is extended to a location lower than a bottom of the inside container main body.
