Definitions

• Container with deformable walls usable as a disposable bin
• the present invention relates to containers with deformable walls and in particular a container which can be made hermetically sealed in a simple and practical manner and which can be used as a disposable bin or easily transportable especially in the field of medical care.
• the aim of the invention is to produce an inexpensive container, solid, simple to use and capable of being hermetically sealed after use.
• Another object of the invention is to provide a container as above which can be used as a portable trash can, mainly for medical care waste.
• Yet another object of the invention is to provide a container made in one piece by extrusion / injection blowing.
• the object of the invention is therefore a container with deformable wall walls comprising a first part consisting of a portion of a surface of determined shape ending at its intersection with a plane which it cuts according to a curve corresponding to a line. of lesser thickness of the wall of the container, this surface being normally closed if it were not limited to a portion, and a second part consisting of a surface symmetrical with the surface of shape determined with respect to the plane and connected to the first part by the line of lesser thickness.
• the second part has an opening for introducing objects into the container.
• the container can be made hermetically sealed by applying pressure on the top of the second part so as to tilt the latter in contact with the first part by rotation relative to the line of least thickness. acting as a hinge so that the opening is blocked by the wall of the first part.
• FIG. 1 represents a container according to an embodiment of the invention
• FIG. 2 represents the container illustrated in the Figure 1 after it has been closed.
• Figure 3 is a partial sectional view of the closed container along line A-A of Figure 2, and Figure 4 shows a particular embodiment of a container using the principles of the invention.
• FIG. 1 represents a container with deformable walls made of plastic material which can be used in various applications and in particular as a portable and inexpensive bin for the disposal of waste from medical care.
• the body of the container 10 intended to receive the waste is extended upwards by a first part 12 in the form of a spherical cap ending at the line 16 located at the intersection of the spherical cap with a plane.
• Line 16 corresponds to a lesser thickness of the wall of the container so as to function as a hinge as will be seen.
• the top part 14 of the container also has the shape of a spherical cap symmetrical with the spherical cap corresponding to the part 12.
• a pressure is exerted on the top of the part 14
• its wall deforms while opposing a force which tends to oppose the pressure exerted.
• part 14 is enough deformed downward, it swings down suddenly using the line 16 of lesser thickness as a hinge, to come to be housed inside the concave part 12.
• This tilting is easier if the convex part 14 is slightly smaller in height than the concave part 12; but this is not obligatory insofar as the plastic walls are sufficiently deformable for the part 14 to be pressed against the part 12 of the same dimension.
• the upper part 12 has an opening 18 through which the waste can be introduced. When the part 14 is pressed inside the concave part 12, the opening 18 is therefore closed off by the wall 12 and the container is therefore hermetically sealed as illustrated in FIG. 2.
• the part 12 has a protrusion 22 outwards.
• the utility of the protrusion 22 is to lock the container. By the same effect as when the container is closed, it suffices to exert pressure on the protuberance 22 to cause it to tilt inside the container. Because the protrusion 22 is symmetrical with the opening 18 relative to the plane of the line 16, the protrusion 22 enters the opening 18 as illustrated in FIG. 3 which is a section through the closed container along line AA of the Figure 2. The wall 26 of the upper part matching the shape of the wall 28 of the concave part, is then locked by the protrusion retracted 1 inside the container.
• 1, 2 and 3 is generally made of plastic material such as polyethylene, or recycled plastic material. But it could also be made of metal which is flexible enough for the walls to be deformable.
• the container can have any size and the part 10 can be more or less deep, even if it is reduced to nothing so that the container is formed by two symmetrical spherical caps.
• a small container can be used as a portable disposable bin.
• a nurse giving care at home will throw there the dressings, bands, fabrics ... having served for his patient and will then close the container as it was described previously before throwing it away, therefore avoiding any risk of contamination.
• the container can be of medium size and serve several times. It is for this reason that a gripping element 20 is provided at the top of the part 14 as illustrated in FIG. 1.
• a gripping element 20 is provided at the top of the part 14 as illustrated in FIG. 1.
• the protrusion 22 can be provided with a gripping element 24 (see Figures 2 and 3) that will suffice to pull to unlock the container.
• the gripping elements 20 and 24 are useful. In fact, transport being an important part of the cost price of a product, it is preferable that the product before use is as compact as possible. With the system of the invention, it is more economical to transport the containers in the closed position and to make them operational by pulling on the gripping element 24 then on the gripping element 20 at the time of use.
• the container is presented as a series of combinations of convex and concave spherical caps. Any combination or set has a diameter which is less than that of the bottom suit and which is greater than that of the top suit.
• the set 30 is smaller than the set 32, itself smaller than the assembly 34, itself smaller than the assembly 36. If the principle described with reference to FIG. 1 is applied by applying pressure to the top of the assembly 30, the upper convex part enters the symmetrical concave part; then this concave assembly at the same time as the convex part of the assembly 32 tilting downwards, forms a concave assembly conforming to the internal shape of the concave part of the assembly 32 .... and so on. In the final phase, the container therefore has the shape of a bowl with each of the parts (convex or concave) embedded in the lower part.
• the above embodiment has a considerable advantage over any other container of the same utility insofar as it is transportable in an extremely reduced form compared to its usable form. Therefore, with this embodiment, the reduced manufacturing cost is added a low transport cost.
• the preferred method of manufacture consists in making the plastic container in one piece by the conventional extrusion blow molding or injection blow molding process. .
• a single mold will suffice, unlike previous methods of manufacturing containers used for the elimination of waste which require at least two molds. It can therefore be seen that the container which has just been described has numerous advantages which can be summarized by: a low manufacturing cost (container of a single piece), reduced dimensions, ease and simplicity of use, speed of handling and good sealing.
