Apparatus for testing water hammer strength of glass bottle

摘要

An object is to prevent a bottle from being inclined when a weight is dropped, and to prevent cushion members from moving due to the impact applied when the bottle is inclined, thereby enabling efficient and correct measurement of the water hammer strength. An apparatus for testing the water hammer strength includes holding element that holds bottle filled with content and sealed with a cap at a position above the center of gravity thereof so as to suspend the bottle in the air, and the holding element is placed on cushion members placed on a fixing stage. A weight is then dropped onto the cap to measure the water hammer strength. The cushion members are compressed and deformed in advance using a compression element for forcing the holding element downward to solve the above-described problems.

主权项

1. An apparatus for testing the water hammer strength of a bottle, said apparatus comprising:
a fixing stage; a cushion member on said fixing stage; a holding element on said cushion member and configured to hold the bottle at a position above the center of gravity thereof so as to suspend the bottle in the air, the bottle being filled with content and sealed with a cap, at least one of said fixing stage and said holding element having a recess in a surface in contact with said cushion member; a weight to be dropped onto the cap of the bottle to apply an impact to the bottle; a compression element configured to forcibly push said holding element downward, wherein said cushion member, said holding element, and said compression element are configured such that said compression member compresses and deforms said cushion member via said holding element; a first non-slip sheet between said fixing stage and said cushion member; and a second non-slip sheet between said cushion member and said holding means; wherein at least one of said first non-slip sheet and said second non-slip sheet is arranged in said recess.
