Definitions

• the present invention relates to a device for the tight closure of bags made of flexible material, where the closure device includes a first section and a second section, being in hinged connection at the one end of each section and adapted so that after movement to a position adjacent to one another (closing position) they take up, fixing between them, the portion of the bag within which it is closed, where in the other end of each section a manually openable snap lock is arranged which automatically closes on movement of the sections towards one another, and where the surface of the first section facing towards the second section has a groove provided in longitudinal direction of the section.
• the present invention relates to a device which meets the above- mentioned requirement;
• the device includes a first section and a second section which are in hinged connection at one end of each section.
• the sections are adapted so that after movement to a position adjacent to one another (closing position) they take up, fixing between them, the portion of the bag within which it is closed.
• each section is provided with a snap lock which on movement of the sections towards one another automatically fixes the sections adjacent to one another and which snap lock is manually openable.
• the first section moreover comprises a groove provided in longitudinal direction of the section and located in the surface of the first section facing towards the second section.
• the second section is provided with a rib located in longitudinal direction of the section the rib, with the sections in closing position, substantially forming a tight fit
• the groove is formed by two slablike elements Situated at a distance from one another, each of which being attached to the first section only along its one edge.
• the first section between the edges just mentioned consists of a material portion which is deformed res liently when the rib is introduced into the groove.
• the edge the rib facing towards the first section in closing position is provided with a rounded shape so that on closure of the bag it guides the rib into the groove and prevents any damage to the flexible material of the bag.
• Fig. 1 shows a perspective view of a device in accordance with the invention with the sections of the device placed at an angle to one another
• Fig. 2 shows a lateral view of the device in extended position.
• Fig. 3 shows the device from above in extended position
• Fig. 4 shows the section 4-4 in Fig. 3
• Fig. 5 shows the device in closing position
• Fig. 6 shows the section 6-6 in Fig. 2 and
• Fig. 7 shows the section 7-7 in Fig. 2.
• first section 1 and a second section 2 which at one end 10, 20 of each .. section are joined to one another by means of a hinge 3.
• the section 1 is provided with a snap hook 12 whilst the second section 2 is provided at its other end 21 with a snap lip 22.
• the sections are, pivotable about the ' hinge 3 in order to assume a position corresponding to that as shown in Fig. 5, when the snap hook 12 and the snap lip 22 co-operate to fasten the sections in the position (closing position) shown in Fig. 5.
• the first section 1 is provided with a groove 13 which is formed with the help of two slablike elements 14, 15 which along their one edge 16, 17 are attached to the remaining parts of the first section. Between the two edges 16, 17 just mentioned the section forms a material portion 18 adapated to be bent along a line between the slablike elements in longitudinal direction of the section so as to twist the slablike elements 14,15 to a limited extent from one another when they are acted upon by forces directed from a vertical plane through the said centre line. For certain applications a certain springiness is permissible also in the slablike elements whilst in other applications, where extra stiffness is desired, for example in case of long slablike elements, reinforcement profiles 19 are arranged along the outsides 32, 33 of the elements.
• the second section 2 is provided with a rib 23 located in longi ⁇ tudinal direction of the section and placed so that when the sections are moved to the position shown in Fig. 5 it can be guided into the groove 13.
• the rib 23 forms a substantially rigid body with an out- wardly facing rounded edge 24.
• the rib 23 is dimensioned so that it can be bent laterally to a certain extent when the rib is introduced into the groove 13. It is evident from the figures that in the embodiment shown the second section is given a U-shaped cross-section into which as a rule is placed at least one reinforcement element 25 so as to increase the mechanical stability of the section.
• the device in accordance with the invention can be used a great number of times. It is realizable in different sizes adapted to the particular closure possibility and elasticity of the particular bag material.
