Definitions

• the present invention relates to a re-closable container for fluid products, particularly adapted to contain products used in the medical, pharmaceutical, cosmetic, food field or the like.
• containers made of polymeric material for the packaging of one or more doses of fluid, liquid or pasty products.
• the known containers can be of the re-closable or disposable type and generally comprise a containment body of a predetermined dose of product, of substantially tubular and elongated conformation, which has an ending part with a neck, at the top of which a product dispensing mouth is defined.
• the opposite ending part of the containment body has an opening adapted to the introduction of the product, which is closed after filling, e.g., by sealing.
• the aforementioned containers comprise closure means, associable in a removable manner with the containers at the neck, and which allow the occlusion of the dispensing mouth.
• the containment body and the closure means can be made separately, by means of forming techniques such as injection molding, and subsequently assembled together or, alternatively, they can be made in a single body piece and then separated before use by a user.
• the containment body also has a pair of flaps that are adapted to facilitate the grip of the container by a user, and which extend, diametrically opposite to each other, from the outer side surface of the containment body itself.
• the known containers can be produced in single units or associated with each other in series to form a so-called "strip"; in the latter case the flaps of the containment bodies of two consecutive containers are temporarily associated with each other at easily tearable weakened- section connection lines, which allow separating one container from the other.
• strip a so-called "strip"
• various types of containers are known according to the different modes of use and implementation.
• a first type of re-closable containers made in a single body piece comprises closure means having a shutter element, of the type of a plug or the like, sealingly inserted into the dispensing mouth, and deformable or breakable elements which connect, without interruption, the closure means to the container body.
• Such deformable or breakable elements are adapted to report to the user the possible presence of product contaminations due to any tampering and/or fortuitous opening of the product, therefore carrying out the function of a warranty seal.
• a second type of containers is also known, wherein the closure means and the containment body are made in separate pieces, subsequently assembled together.
• the closure means of such containers generally comprise a handle with a shutter element, of the type of a plug or the like sealingly insertable in the dispensing mouth, and an annular collar securable coaxial and interlocking at the neck of the containment body.
• the handle is associated removable at the outer surface of the collar through an appropriate weakened area, consisting e.g. of pre-breaking lines, tearable bridges, reduced transverse sections or the like.
• the handle, the collar and the plug are therefore made in a single body piece, separately from the containment body, and the collar is subsequently secured to the neck by interlocking, the dispensing mouth being closed by means of the
• Plug- Containers of this type are shown in the patent document EP 1289842 Bl.
• a third type of known containers provides for, e.g., the use of a closure element which, during the molding step, is made with a portion secured to the neck of the container along predetermined breaking areas to occlude the dispensing mouth.
• the containment body and the closure element are made in a single body piece so that the dispensing mouth of the container is initially closed and can be opened by tearing the closure element off the containment body.
• the closure element can also comprise a cap-shaped seat delimited by a side wall and a bottom wall, which is arranged on the opposite side with respect to the portion initially secured to the neck and which has a shutter body extending from the bottom of the cap-shaped seat and is sized so as to be introduced into the dispensing mouth.
• the container is opened for the first time by detaching the closure element from the dispensing opening at the breaking areas and, after using the product, the container can be closed again by overturning the closure element and by fitting the cap- shaped seat on the neck, by positioning the shutter body into the dispensing mouth.
• the cap-shaped seat becomes the receptacle of contaminating agents and, once fitted around the neck of the container, has the bottom wall in contact with the dispensing mouth, greatly facilitating the inlet of contaminating agents in the latter and therefore in the product.
• the particular conformation of the closure element leads to the exposure to external contaminating agents before the first use of the container, thus not ensuring the integrity of the product during its subsequent uses.
• the main aim of the present invention is to provide for a re-closable container for fluid products, particularly for medical products, pharmaceuticals, cosmetics, food or the like, which greatly reduces the risk of contamination of the product contained in the container itself by contaminating agents.
• Another object of the present invention is to provide for a re-closable container for fluid products wherein the dispensing mouth is isolated from contact with contaminating agents, thus ensuring the integrity of the product during its different uses.
• a further object of the present invention is to provide for a re-closable container for fluid products, particularly for medical products, pharmaceuticals, cosmetics, food or the like, which allows to overcome the mentioned drawbacks of the prior art within the ambit of a simple, rational, easy, effective to use and affordable solution.
