Definitions
- Container with solid walls, container interior and opening for filling the container and method for using the container
- the invention relates to a container with a solid wall, a container interior and an opening for filling the container with a product such as objects or a liquid.
- the invention also relates to a method for using a container with a solid wall and a container interior, in which the container is filled.
- Such containers are known as cans, boxes, bottles, etc.
- the problem sometimes arises that the container is only partially filled and there is air above the contents in the interior of the container. This air can cause the contents in the container to oxidize or even spoil.
- the invention is based on the object of proposing a simple container and a simple method which make it possible to store contents in a container and to minimize the access of air to the contents.
- This object is achieved in a generic container in that it has a guide with a piston in the wall, the piston being held in the guide, and that it has a valve that allows air to escape from the container when the piston is moved towards the interior of the container.
- the guide is the inside of the solid wall, which interacts with the piston.
- the object is achieved with a method for using a container with a solid wall and a container interior, in which the container is filled and then air is removed from the container with a piston by pushing the piston into the interior of the container.
- the invention is thus based on the knowledge that the interior of the container is freed of excess air by reducing the size of the interior of the container. For this purpose, a piece of the wall is pushed into the interior of the container as a piston. This creates an overpressure in the interior of the container. This overpressure escapes through a valve. This leaves a container that is filled with a product, with only as little air as possible in the interior of the container.
- a first embodiment provides that the container is a can.
- the container can also be a bottle or a carafe.
- Bottles are usually produced in a blow mold.
- an exactly dimensionally stable outer shape is created.
- the inside of such a glass bottle is uneven, however, since the shape there is only created by the excess pressure applied during blowing. It is therefore difficult to guide a piston there and, in particular, to even design this piston in a sealing manner.
- the glass bottle has a round cross section and the piston in its guide direction has a height that is greater than 20% of the diameter of the cross section of the glass bottle.
- the piston can for example have a height of more than 5 cm. This enables a good seal without having to worry about tilting, which would result in a leak.
- the valve is preferably arranged in a stopper of the container such as, in particular, a bottle stopper. This makes it possible to expel air from the container and in particular the bottle via the valve when the piston moves inwards.
- the valve is designed so that the piston can only be pushed slowly and therefore carefully into the bottle. At the latest when liquid fluid leaks from the valve, the inward movement of the piston is interrupted. Then the valve closes so that the piston can no longer sink because the air pressure pushes it into the bottle.
- the stopper has a rubber contact surface around the valve outside the container. This makes it possible to hold the stopper, which is located in the container, in particular the bottle, against a tap in order to fill the bottle with water via the valve. The piston is pushed outwards and the water is then used to clean the bottle.
- the piston has a plastically or elastically deformable piston surface in order to apply the surface to the contour of the filling material, such as an object or several objects.
- the piston has a deformable cushion on its piston surface in order to place the cushion against the contour of the filling material.
- This pillow can be filled with a liquid.
- One possible embodiment variant provides that the wall, the guide and the piston are designed in one piece.
- the container has a base and the valve is arranged opposite the base in the wall.
- a seal be arranged between the wall and the piston.
- the container has a lid.
- the valve can then be arranged in the lid or in the fixed wall of the container.
- the solid wall can also be guided in the cover in such a way that it can be used as a piston to reduce the size of the container interior. If, for example, a lid is designed like a matching can but with a slightly larger diameter, the lid can be pushed onto the can. Air escapes through the valve, preferably until the lid touches the product.
- the container can also have a spring which presses the piston into the interior of the container. To tension the spring, the product can be pressed until the bottom of the container is pressed down so far that the product can be inserted. Then, for example, by pressing the filling material again, a catch can be released so that the bottom is pressed upwards by the spring until the air has escaped from the interior of the container through the valve.
- the container has a bottle opening that is round in cross section and a plunger whose diameter is smaller than the diameter of the bottle opening. This makes it possible to press the piston down or out of the container with a wooden spoon-like plunger in order to be able to refill the container afterwards.
- FIG. 1 shows a section through a container with a deformable piston surface
- FIG. 2 shows a section through a container with a lid guided in the lower part
- Figure 3 shows a section through a container with a spring
- FIG. 4 schematically shows a pressure piece for moving the piston.
- FIG. 1 shows a container 1 with a solid wall 2, a container interior 3 and an opening 4 for filling the container 1 with a product 5.
- the product 5 is in the present embodiment A piece of meat. However, it can also be a liquid or piece goods such as rice etc.
- the wall 2 has a guide 6 with a piston 7 which is held on the guide 6.
- the guide is the inside of the container.
- the container 1 has a lid 8 which has a valve 9 which allows air 10 to escape from the container 1 when the lid is closed and when the piston is moved towards the interior of the container.
- a cushion 11 On the upper side of the piston 7 is a cushion 11 which forms a plastically or elastically deformable piston surface 12 which rests against the contour of the filling material 5.
- This cushion 11 is filled with water as liquid 13.
- the piston 7 forms the base 14 and therefore the valve 9 arranged in the cover 8 is arranged opposite the base 14 in the wall 2.
- a seal 16 is arranged between the wall 2 and the piston 7
- the container shown thus makes it possible to push the piston towards the interior of the container 3 by means of pressure on the piston holder 15 and thus to expel the air 10 through the valve 9 from the interior of the container 3.
- the container 20 in FIG. 2 has a lower part 21 and a lid 22 which fits so precisely on the lower part 21 that air 23 escapes from the container through the valve 24 when the lid 22 is placed on the lower part 21.
- a spring 31 presses a base 32 of the container upwards in the direction of a cover 33 in which a valve 34 is provided.
- This base 32 can be pressed down against the force of the spring 31 and it latches in a lower position on the latching elements 35, 36. This makes it possible to fill the container 30. Thereafter, the locking elements 35, 36 the locking is released so that the spring 31 presses the base 32 upwards until the filling material 37 is pressed against the cover 33. Air escapes from the container 30 through the valve 34.
- the latching elements 35, 36 can be designed in such a way that they hold the base 32 firmly at the maximum height at which the filling material 37 rests on the cover 33. This leads to the filling material 37 being stored in the container free of air and not being pressed out of the container 30 when the lid 33 is opened.
- FIG. 4 shows the lower area of a bottle 40, which is open at the bottom, as a container.
- the piston 41 is pushed into this bottle 40 with a pressure piece 42.
- a lip seal 43 running around the piston 41 seals the piston 41 against the inside of the bottle 40 serving as a guide.
- the pressure piece 42 makes it easier to push the piston 41 into the bottle 40. In order to pull the piston 41 out of the bottle 40 again, the pressure piece has
- suction cup 44 which is arranged on the side 45 of the pressure piece 42 which interacts with the underside 46 of the piston 41.
- the suction cup 44 can thus press the underside 46 of the piston 41 into the bottle and in doing so it sucks itself firmly against the underside 46.
- the piston 41 can also be pulled out of the bottle 40 again with the pressure piece 42.
- the suction cup 44 In order to detach the suction cup 44 from the underside 46 of the piston 41, the suction cup 44 has a valve 47 which can be opened via a valve tappet 48 guided in the pressure piece 42.
- the valve tappet 48 has a push button 49 which is arranged on a handle knob 50 of the pressure piece 42.
- the piston 41 is inserted into the bottle 40 as a pressure cylinder in such a way that the lip seal 43 sits approx. 20 mm in the bottle 40.
- the lip seal
- the bottle with the open bottom can also be closed with a valve closure (not shown). Then air escapes through the valve cap until the wine in the bottle has reached the top of the bottle. Then there is no more air in the bottle and the valve closure prevents air from entering the bottle. The volume of the bottle can thus be reduced with the piston until there is only liquid in the bottle. Air can already escape through a valve closure or the bottle is closed with a normal closure when there is no more air in the bottle.
- the suction cup 44 sucks on the piston 41.
- the valve plunger 48 can be pressed approximately 3 mm in the direction of the piston 41 with the push button 49 in order to close the valve 47 in the suction cup 44.
- the underside 46 of the piston 41 is then connected to the pressure piece 42 via the suction cup 44 and can now be pulled out of the bottle 40.
