Abstract

A plastic container is disclosed which can include a pour spout for mounting on a container neck and having one or more closable pour openings. At least one blow molded cam can project over a neck wall of the container neck, the pour spout having a body configured for connection to the container neck, and made to correspond with a peripheral contour of the container neck and to have a corresponding number of receptacles for cam(s) in a wall facing the neck wall. For example, at least one cam is formed in an inside wall of the container neck.

Claims

exact text as granted — not AI-modified
1 . A plastic container, comprising:
 a pour spout for mounting on a container neck and having one or more closable pour openings; and   at least one blow molded cam which projects over a neck wall of the container neck, the pour spout having a body configured for connection to the container neck, and made to correspond with a peripheral contour of the container neck and to have a corresponding number o f receptacles for cam(s) in a wall facing the neck wall which is provided with at least one cam, wherein the at least one cam is formed in an inside wall of the container neck and wherein the at least one receptacle is formed in an outside wall of the body of the pour spout.   
     
     
         2 . The plastic container with a pour spout as claimed in  claim 1 , wherein at least one cam opposite the neck wall has a projection from 1.3 mm to 8 mm. 
     
     
         3 . The plastic container with a pour spout as claimed in  claim 1 , wherein the at least one cam has an extension from 3 mm to 8 mm measured in a peripheral direction of the neck wall. 
     
     
         4 . The plastic container with a pour spout as claimed in  claim 1 , wherein the at least one cam is in a mold removal plane of a blow mold. 
     
     
         5 . The plastic container with a pour spout as claimed in  claim 1 , wherein the container neck has an essentially rotationally symmetrical peripheral contour. 
     
     
         6 . The plastic container with a pour spout as claimed in  claim 1 , wherein the at least one receptacle extends in the body of the pour spout as far as a free end of the body. 
     
     
         7 . The plastic container with a pour spout as claimed in  claim 6 , wherein the at least one receptacle runs into a centering guide whose extension measured in the peripheral direction widens in a direction of the free end of the body. 
     
     
         8 . The plastic container with a pour spout as claimed in  claim 1 , wherein the at least one receptacle is a link guide for the at least one cam which runs in a peripheral direction and extends over an angular range from 45° to 90°. 
     
     
         9 . The plastic container as claimed in  claim 8 , wherein the pour spout comprises:
 a pour opening configured to overlap an opening on the container neck when the pour spout is twisted relative to the container neck.   
     
     
         10 . The plastic container with a pour spout as claimed in  claim 9 , wherein the at least one receptacle in the body of the pour spout is a link guide for the at least one cam which extends in the peripheral direction over an angular range from 45° to 90° and is arranged to run obliquely such that a twisting of the pour spout relative to the container neck will axially displace the pour spout out of the container neck or back again. 
     
     
         11 . The plastic container with a pour spout as claimed  claim 10 , wherein the pour spout comprises:
 a pour opening located in the side wall of the body, and configured to open only in an axially extended position of the pour spout.   
     
     
         12 . The plastic container with a pour spout as claimed in  claim 11 , wherein two end sections of the link guide comprise:
 catch projections for the cam.   
     
     
         13 . The plastic container with a pour spout as claimed in  claim 1 , configured as an extrusion blow molded container. 
     
     
         14 . The plastic container with a pour spout as claimed in  claim 1 , configured with a plastic injected pour spout. 
     
     
         15 . The plastic container with a pour spout as claimed in  claim 2 , wherein the at least one cam has an extension from 3 mm to 8 mm measured in a peripheral direction of the neck wall. 
     
     
         16 . The plastic container with a pour spout as claimed in  claim 15 , wherein the at least one cam is in a mold removal plane of a blow mold. 
     
     
         17 . The plastic container with a pour spout as claimed in  claim 16 , wherein the container neck has an essentially rotationally symmetrical, circular peripheral contour. 
     
     
         18 . The plastic container with a pour spout as claimed in  claim 17 , wherein the at least one receptacle extends in the body of the pour spout as far as a free end of the body. 
     
     
         19 . The plastic container with a pour spout as claimed in  claim 17 , wherein the at least one receptacle is a link guide for the at least one cam which runs in a peripheral direction and extends over an angular range from 45° to 90°. 
     
     
         20 . The plastic container with a pour spout as claimed  claim 8 , wherein the pour spout comprises:
 a pour opening located in the side wall of the body, and configured to open only in an axially extended position of the pour spout.
