Container

Abstract

If the diameter of an opening side neck portion is decreased to minimize the contact surface between contents and air and a small cap is fitted on a container where there is the concern that exposure to air may alter the quality of contents in the container, there is not only the problem that a gap results between the cap top board and the container opening where adequate locking force is not available but the problem that force is required to open and close the lid, making removal and fitting troublesome. A container made so a large cap can be fitted thereto by providing a cap locking neck portion 30 whose inner and outer diameters are larger than an opening side neck portion 13 at a container should side neck portion 14 of a container neck 10.

1 . A container provided with a cap locking neck whose inner and outer diameters are larger than those of an opening side neck portion at a container shoulder side neck portion of a container neck. 
   
   
       2 . A container for furnishing extrusion flexibility to a cap locking neck portion in the container described in  claim 1 .

       5 . A container in which a screwing construction comprises a rotation screw closing construction no more than 90 degrees of a cap in the container described in  claim 4 . 
   
   
       6 . A container in which a screwing construction comprises a multi-threaded screwing construction in the container described in  claim 4 . 
   
   
       7 . A container provided with a stopping stopper that can be released with a reverse movement at a cap locking neck portion of a container neck in the container described in  claim 1 . 
   
   
       8 . A container in which a stopper comprises a click stop mechanism in the container described in  claim 7 . 
   
   
       9 . A container in which a cap locking neck portion comprises a press locking construction in the container described in  claim 1 . 
   
   
       10 . A container constituted such that a push locking construction is provided with a locking level portion at a large diameter neck, and mounting of a cap completes when a locking projection provided at a cap skirt portion engages the above-mentioned locking level portion due to pushing in the container described in  claim 9 . 
   
   
       11 . A container provided with a locking level portion where a neck portion between a large diameter neck portion and a container shoulder portion is made with a small diameter in the container described in  claim 10 . 
   
   
       12 . A container wherein a push locking construction is a click stop type in the container described in  claim 9 . 
   
   
       13 . A container wherein a border portion between an opening side neck portion of a container neck and a cap locking neck portion is a cap adhesion elastic structure in the container described in  claim 1 . 
   
   
       14 . A container whose cap adhesion elastic structure comprises a concave cross-section in the container described in  claim 13 . 
   
   
       15 . A container whose cap adhesion elastic structure is provided an inner diameter at least as large as that of an opening in the container described in  claim 13 . 
   
   
       16 . A container whose cap adhesion elastic structure comprises a connecting frame portion for connecting to an opening side neck portion and a cap locking neck portion in the container described in  claim 13 . 
   
   
       17 . A container whose connecting frame portion comprises a dish shape in the container described in  claim 16 . 
   
   
       18 . A container whose connecting frame portion comprises a concave cross-section in the container described in  claim 16 .
