A bag clamping arrangement, such as an arrangement for automatically controlling the filling volume and overflow of a liquid conducted into a flexible bag which is clamped in the arrangement. The bag clamping arrangement is essentially constituted of a rigid upwardly open receptacle of substantially rectangular or a relatively large upper compartment, and wherein a narrow compartment which in open communication with the upper compartment depends downwardly from the bottom of the upper compartment so as to extend longitudinally and generally centrally across the full width of the receptacle. The lower compartment includes opposite parallel sidewalls which are down so as to form a reducing compartment width therebetween. Towards the lower end of the compartment is a plate-like clamping arrangement essentially constituted of a flat plate member which may be manually engaged through an elongate slot and gripping portion proximate its upper horizontal edge. The plate member is provided along its lower edge on both sides thereof with sideways projecting resilient clamping components which, upon being inserted into the lower compartment of the receptacle, are biased towards the plate member and are dimensioned to clampingly engage between the sides of the clamping plate and the contiguous sidewalls of the lower compartment. A flexible bag is positioned on either one side, or two bags each respectively on the opposite sides of the clamping plate member prior to insertion of the latter into the receptacle, with the lower end portion of the bag or bags extending between the respective resilient clamping component and the facing surface of the clamping plate member such that, upon introduction of the clamping plate member downwardly into the lower compartment, the applicable resilient clamping component upon being biased towards the plate member, will clamp the lower bag portion against the facing surface of the clamping plate member, thereby ensuring the secure clamping of the bag.
