Definitions
- the present invention relates to an improved closing device for containers of different types, such as bottles, cans, medicine phials and the like.
- screw caps A multitude of goods are sold in containers of different kinds where the container can be opened and closed using a screw cap.
- the opening and closing of screw caps usually requires two hands.
- screw caps may be difficult to open if they have been screwed on tight or for persons who are physically disabled.
- Opening and closing devices which can easily be opened and closed repeatedly, for bottles with a bead around the upper end of the neck are known from US 2,903,148, US 3,973,688 and DE 3009568.
- a common feature of these opening and closing devices is that they comprise a flexible internal sealing member that is slidably mounted in a cavity in a rigid outer cap.
- the cavity in the outer cap is a substantially conical bore.
- An opening and closing device for bottles with a threaded neck is known from PCT/NO01/00449, later WO 02/38461.
- This device comprises a plurality of retainers that are pressed into engagement with a bottom part by means of an outer part that lies around the retainers and is movable along the longitudinal axis of the bottle.
- the solution is difficult and expensive to produce, and it protrudes from the neck of a bottle more than a traditional screw cap. This could cause problems when bottles on which this device has been fitted are to be placed and transported in the crates for bottles that exist today.
- a closing device for the repeated opening and closing of a container, comprising a base member and a top member, wherein there is an opening in the base member, wherein the base member is adapted to be secured to a container opening on the container or is a part of the container opening, and the top member is adapted to be locked to the base member and to close the opening, wherein a ring of retainers adapted to be inserted into the opening is provided on the top member, wherein an axially extending flange or edge adapted to engage with projections on the retainers is provided in the opening, and wherein a press member adapted to press the retainers out against the base member and into engagement with the edge or flange is provided in the top member.
- the retainers are elastic and retract from engagement with the edge or flange when they are not pressed by the press member.
- the press member is an elastic body that is fastened to a central portion of the top member so that the elastic body is moved into a position in which it does not press on the retainers when the central portion is pressed down.
- the central portion is elastically mounted in the top member in such manner that the central portion is drawn up and draws the elastic body with it when pressure on the central portion ceases.
- Figure 1 is a longitudinal section through a first embodiment of the present opening and closing device in a closed position
- Figure 2 is a longitudinal section through the opening and closing device shown in
- Figure 3 is a longitudinal section through a second embodiment of the present opening and closing device in a closed position;
- Figure 4 is a longitudinal section through the opening and closed device shown in
- Figure 5 is a longitudinal section through the embodiment of the device shown in
- Figure 7 is a section though a perspective view of the device shown in Figure 3.
- Figures 1 and 2 show a section through a first preferred embodiment of the present device in a closed and open position respectively.
- the illustrated device comprises a base member 1, a top member 2 and a closing member 3.
- the base member 1 is designed to replace a standard screw cap and comprises a cylindrical wall 4 and a top plate 5.
- the inner surface of the cylindrical wall is equipped with internal threads 6 adapted to the threads on the neck of the bottle.
- An annular seal 7 which rests against the top plate 5 ensures sealing between the base member 4 and the non-illustrated top of the neck of the bottle.
- the top member 2 and the closing member 3 are fitted together so that they form one unit.
- the top member is preferably connected to the base member 1 by an arm 13.
- the arm 13 is preferably fastened to the base member 1 and can be moulded in one piece therewith.
- the arm preferably has a trapezoidal cross-section and runs in the top member 2 in a non-illustrated groove having a trapezoidal cross-section that runs across the top member.
- the length of the arm 13 can be adjusted by means of a manipulator button 14.
- the manipulator button 14 may optionally be adapted for engagement with grooves in the top member so that it can be locked in one or more positions.
- the closing member 3 is arranged to be axially movable on a core portion 10 of the top member 2.
- the core portion 10 runs in an axial bore in the closing member 3.
- the central bore in the closing member 3 is surrounded by a ring of retainers 11 which project down from an annular supporting member 15 away from the top member 2.
- An annular seal 12 is provided on the supporting member 15 to seal between the top of the base member 1 and the supporting member 15 when the device is closed.
- Figure 2 shows the same embodiment as that shown in Figure 1 in an open position, wherein the closing member has been placed against the base member 1.
- the ring of retainers 11 from the closing member has been placed against a central bore 9 in the base member.
- the retainers 11 are made of an elastic material and their lower ends are drawn in towards the longitudinal axis of the device by the material.
- the ring of retainers 11 has a total diameter that allows this ring to be inserted into the central bore 9. To close the present device, the ring of retainers 11 is passed into the central bore 9.
- the closing member 3 has been placed against the base member 1 so that the supporting member 15 rests against the base member 1, the top member 2 is pressed down against the closing member.
- the core portion 10 is then pressed down into the ring of retainers and presses the retainers out from the longitudinal axis of the device.
- the retainers 11 then engage below the bore 9, preferably with the bottom edge of a cylindrical flange 8 that projects axially downwards from the bore 9, as shown in Figure 2.
- the device is now closed, but can be opened again by pulling the top member 2 up, thereby pulling the core portion out of the ring of retainers so that the retainers disengage from the base member 1.
- the closing member is then pulled up with the top member, and the bottle is open.
- a flange 8 should be arranged in connection with the central bore 9 is that the retainers 11 have limited elasticity. When a flange is provided below the bore, it is easier to press the retainers 11 into engagement with the base member.
- Non-illustrated pins which slide between the retainers 11 are preferably arranged on the core portion 10.
- the non-illustrated pins prevent the closing member 3 from falling off the top member and ensure that the closing member is taken out of the base member together with the top member.
- the core portion 10 is slightly conical, with its smallest diameter at the bottom. This ensures that the core portion 10 fits snugly against the closing member when the device is closed. It is also preferable that there should be a small flange on the upper side of the bore 9 on the base member for abutment against the seal 12. However, this small flange is not strictly speaking necessary as the seal 12 may be designed for direct abutment against the top of the base member.
- the external diameter of the flange 8 is adapted to the internal diameter of the neck of a bottle, so that the flange 8 projects down into the neck when the device is screwed onto a bottle.
- FIG. 3 shows an embodiment of the present invention in the form of a bottle cap, in a position in which the cap is closed. The retainers 27 are then pressed out against the base member 20 by the elastic body 24.
- FIG. 5 shows the device when the elastic body 24 is pressed down below the retainers 27, thereby allowing the projections to disengage from the edge or flange 25 so that the top member 21 can be pulled up and out of the base member, and the device is open.
- the opening 31 is slightly conical with the smallest opening at the top so that the retainers rest against the edge of the opening at the top and are thus pressed out of engagement with the edge or flange 25.
- the central portion 22 that is mounted in the elastic intermediate member 23 will be drawn up and will draw the elastic body with it.
- the elastic body 24 will then in turn pull up the inside of the ring of retainers and press the retainers outwards.
- the elastic body When the top member is replaced on the base member, the elastic body will be compressed so that the ring of retainers can be put into the top member, and will press the retainers out against the edge of the opening 31 and into engagement with the edge or flange 25 so as to close the device.
- the present device When it is required or desirable that the present device should be almost air or watertight, it must be sealed with one or more seals between the base member and the top member. This is shown in the figures by a seal 26. However, there may be a question of optimising the location of the seal. It is also possible that it may be advantageous for the seal to be fastened to the top member.
- the main part 19, the central portion 22, the intermediate member 23 and the retainers 27, 28 are preferably made in one piece.
- the base member is designed to be fastened to the container on which the device is to be used.
- the base member may be threads, as shown in Figures 1 and 2, or there may be other means on the base member for fastening to the container.
- the base member does not need to be a separate part. If the container opening is made so that but can also be a part of the container.
