Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 6, the present invention provides a schematic diagram of EVOH contained in the bottom of the container wall of the container body, and the bottom of the inner layer of the container body:

example 1

Container wall bottom adhesion barrier method:

s1: as shown in fig. 1 and fig. 2, for the container of EVOH (2) barrier layer is pasted to the bottom of mould inner wall: preparing EVOH (2) material, placing the prepared EVOH material at the bottom of the inner wall of a mold in advance, and keeping a barrier label paper layer (3) in place in the mold usually by vacuum or other special positioning devices; the method comprises the following steps of (1) inversely placing a mold, feeding glue from the bottom end outside the mold, closing a movable mold and a fixed mold of the mold, opening a first hot runner, injecting a molten pp (1) material into a mold cavity from the injection molding direction of the mold through the first hot runner, and fusing an EVOH (2) material in the molten pp (1) by utilizing the heat of the molten pp (1); at this time, the outer shape of the molded container is completed.

As shown in fig. 3 and 4, for the utility model provides a EVOH (2) barrier layer is pasted to the bottom of mould outer wall: preparing a barrier label paper layer (3) containing EVOH (2) material with barrier property, placing the barrier label paper layer (3) on the bottom of the outer wall of the mold in advance, and keeping the barrier label paper layer (3) in place on the bottom of the outer wall of the mold usually by vacuum or other special positioning devices; feeding glue from the interior of the mold, closing a movable mold and a fixed mold of the mold, opening a first hot runner, injecting molten pp (1) material into a mold cavity from the injection molding direction of the interior of the mold through the first hot runner, and fusing EVOH (2) material with barrier property in the molten pp (1) by utilizing the heat of the molten pp (1); at this time, the outer shape of the molded container is completed.

S2: and adhering an EVOH (2) barrier layer at the bottom of the inner wall of the mould or adhering an EVOH (2) barrier layer at the bottom of the outer wall of the mould to the container obtained in the step, and adhering a barrier label paper (3) containing EVOH (2) material to the outer wall of the container.

Example 2

Method of filling the barrier layer at the bottom of the container: as shown in fig. 5 and 6, the moving mold and the fixed mold of the mold are closed, the first hot runner is opened, molten pp1 material is injected into the mold cavity of the mold from the injection direction of the arrow on the drawing through the first hot runner, then the first hot runner is turned off, when the injected pp1 layer is not formed, the second hot runner is opened, EVOH2 material with barrier property is injected into the not formed pp1 layer until a preset value is reached or the whole pp1 layer at the bottom of the container is filled with EVOH2 material, the EVOH2 material forms an EVOH2 barrier layer in the pp1 layer at the bottom, and the second hot runner is turned off; then a small amount of pp1 seal is filled again at the entrance of the injection molding direction of the arrow on the figure, and then the barrier label paper is pasted on the outer part of the container wall to achieve the outer periphery barrier effect.

Further, after the EVOH2 reaches a preset value or the whole PP1 layer of the bottom of the container is filled with the EVOH2 material in the example 2, the EVOH2 material is injected continuously until the EVOH2 material spreads from the PP1 layer of the bottom of the mold to 20mm-50mm above the PP1 layer of the bottom of the mold, or the time of the injection of the second hot runner reaches a preset time, the second hot runner is closed, the EVOH2 material is stopped being injected, and then barrier paper is attached to the outer part of the container wall to achieve the outer periphery barrier effect.

Further, in the further description above, after the EVOH2 material has spread from within the bottom pp1 layer of the mold to 20mm-50mm above the bottom pp1 layer of the mold, the injection of the EVOH2 material is continued until the EVOH2 material fills the entire pp1 layer of the container body raw material or the time of the second hot runner injection reaches a predetermined time, the EVOH (2) material forms an EVOH (2) barrier within the pp (1) layers of the bottom and the container body, the second hot runner is closed to stop the injection of the EVOH2 material, and then a barrier label is attached to the exterior of the container wall to achieve an exterior peripheral barrier effect.

Preferably, the container cover is sealed by the barrier label paper layer 3, so that the whole container is completely blocked, and cost is saved and the barrier is high in efficiency.
