Container with integral module for heating or cooling the contents and method for its manufacture

A container having a container body, a thermic module at one end of the body, and a closure at the other end of the body initiates an internal exothermic (or, alternatively, endothermic) chemical reaction to heat its contents when a user actuates the thermic module. A plastic thermic module body is spin-welded to a plastic container body by rotating one relative to and in contact with the other. The container body has multiple layers, including an inner layer such as a so-called oxygen barrier layer that inhibits oxidation and spoilage of the contents, and spin-welding the container body to the module body seals the otherwise-exposed oxygen barrier layer against air or moisture intrusion. The container includes a rotatable cover adhered to the container end over the closure with heat-sensitive adhesive that prevents a user from accessing the contents until a certain temperature is reached. The thermic module further includes a seal between an inner actuator button and an outer actuator ...

PROCEEDED Of OBTAINING a THERMOPLASTIC PACKING IN FORM OF LIMPS

Curved plastic pipe used e.g. in vehicle ventilation system blow-moulded in one piece in sections which are cut and assembled after moulding

The procedure consists of blow-moulding the pipe in one piece made from a number of sections (12, 13, 14) lying more or less in line with the lengthwise axis (17) of the preform. The sections are linked by portions (19) which are cut away after moulding, leaving orifices (22, 23) on the ends of pipe sections which are linked by supple connectors (21) which act as hinges as the orifices are brought together and the adjoining sections are assembled to make a continuous curved pipe. The pipe can be packed and stored as a one-piece moulded component and unpacked and assembled prior to use. One of each pair of assembled orifices is made with an assembly projection (18) during moulding, allowing it to be clipped or stuck to the adjoining pipe section, and the portions (19) of the moulding to be cut away prior to assembly are in the form of bubbles.

在利用吹塑成形品的制造装置(10)制造吹塑成形品时，利用隔着片状型坯(P)配置的一对成形模具(17a、18a)和另一对成形模具(18b、17b)，使片状型坯(P)形成为规定形状。接着，由活塞部(19)将内置部件(20a、20b)固定在成形的片状型坯(P)上，之后，由切割刀具(25)对片状型坯(P)的、利用一对成形模具(17a、18a)成形的成形部分与利用另一对成形模具(18b、17b)成形的成形部分之间进行切割。在该切割完毕后，使规定的成形模具(17a、17b)相向，对两者进行合模。从而使成形的两个片状型坯(P1、P2)紧闭接合，形成吹塑成形品(P3)。

Method For Blow Molding Tubular Container

본 발명은 포장용기의 블로우 성형방법에 관한 것으로, 포장용기의 몸통 측면에 투명부를 갖는 포장용기를 블로우 성형할 때, 포장용기의 몸통 측면에 성형되는 투명부가 변형되는 것을 방지하고, 투명부의 상부 및 하부가 일정한 폭으로 곧고 균일하게 성형되도록 하는 것이다. The present invention relates to a blow molding method of a packaging container, and when blow molding the packaging container having a transparent portion on the body side of the packaging container, to prevent deformation of the transparent portion formed on the body side of the packaging container, the upper portion and The lower part is to be straight and uniformly formed in a constant width. 본 발명의 포장용기의 블로우 성형방법은, 압출기(1)에서 용융 압출된 수지원료 튜브(T)를 관상 성형부(2)를 통해 하강시키는 제1단계와; 좌우로 벌어지는 하나 이상의 용기금형(3)이 관상 성형부(2)의 직하방으로 이동하여서 상기 1단계에서 하강하는 수지원료 튜브(T)를 파지하는 제2단계와; 상기 용기금형(3)에 의해 파지된 수지원료 튜브(T)의 상단 주입구를 가열된 커터(4)로 컷팅하는 제3단계와; 상기 수지원료 튜브(T)를 파지한 용기금형(3)이 에어노즐(5) 직하방으로 이동하는 제4단계와; 상기 용기금형(3)의 상단 주입구에 에어노즐(5)이 하강한 다음, 용기금형 내부로 공기를 주입하여 수지원료 튜브(T)를 금형 벽면으로 눌러서 포장용기로 부형하는 제5단계와; 통 형상으로 부형된 포장용기를 냉각하여 용기금형(3)에서 꺼내고, 용기의 위쪽과 아래쪽 잔여물을 절단하여 포장용기를 제조하는 제6단계; 로 이루어진 포장용기의 블로우 성형방법에 있어서, The blow molding method of the packaging container of the present invention includes a first step of lowering the water support material tube T melt-extruded in the extruder 1 through the tubular molding part 2; A second step of holding one or more container molds (3) spreading from side to side directly under the tubular molding part (2) to hold the water support material tube (T) descending in the first step; A third step of cutting the upper inlet of the water support tube T held by the container mold 3 with the heated cutter 4; A fourth step in which the container mold (3) holding the water support tube (T) moves directly under the air nozzle (5); A fifth step of lowering the air nozzle 5 into the upper injection hole of the container mold 3 and then injecting air into the container mold to press the water support material tube T into the mold wall to form a packaging container; A sixth step of cooling the packaging container shaped into a cylindrical ...

Making synthetic resin can body by injection or extrusion and blow moulding

The present invention provides an inexpensive method for manufacturing synthetic resin can bodies, the method comprising the steps of molding a preform with a bottom formed of thermoplastic synthetic resin such as polyethyleneterephthalate; stretch blow molding a bottlelike intermediate member in which an upper end (5) of a body portion (4a) is outwardly extended from the preform; and cutting the intermediate member at the extended portion top form a can body in which a body portion having at least a laterally directed open edge by a lower side of the extended portion and a bottom are integrally formed.

Plastic pallet - blow-moulded from low pressure polyethylene

A pallet (esp. a non-returnable pallet) is mfrd. by first blow-moulding a hollow body having rel. low height and then dividing same into two parts each half as high as the first blow-moulding, thereby forming two pallet decks. The material used may be low pressure polyethylene. This is claimed to be an inexpensive and rel. simple method of mfrg. strong and stable pallets.

Apparatus for extrusion-blow molding a bottle for assembly with metal can end

An extrusion blow mold for forming a plastic bottle having a radial flange suitable for roll-form attachment to a metal can end. The mold has a pair of confronting mold halves, each mold half including a body forming portion, a bottom pinch-off portion located below the body forming portion, a top block portion including a blow chamber located above the body forming portion, and a spin-ring forming portion located between the body forming portion and the top block portion. The spin-ring forming portion includes a thread ring insert and a cutter ring insert. The thread ring insert has an inside upper edge including an outwardly extending surface terminating in a step defining a lower surface and a outer edge of a radial flange. The cutter ring insert is positioned immediately above the thread ring insert. The cutter ring insert has a lower surface adjacent an inside edge defining an upper surface of the radial flange including a tapered inner edge extending upward and inward from the step. At least one of the thread ring insert and cutter ring insert includes a relief surface connected to a vent channel to permit gas to escape from the area defining the radial flange.
