Description

IMPROVED BOTTLE FOR FLUID PRODUCTS, PARTICULARLY PHARMACEUTICAL PRODUCTS. DOCTORS OR COSMETICS TECHNICAL FIELD The present invention relates to an improved bottle for fluid products, particularly pharmaceutical, medicinal or cosmetic products.

TECHNICAL BACKGROUND Plastic bottles are known to be used in pharmaceutical and cosmetic industries to pack one or more doses of fluid, liquid or pasty products and are essentially made from a container body to contain the product which, at one end, extends into a neck , in the upper part of which a product supply nozzle is defined; the dispensing nozzle is closed by means of a tear-off membrane. The end of the container body opposite the neck is open to allow, during the packaging of the bottle, the introduction of the product into the container body, after which it is closed, for example by sealing.

On the neck, a cover is fitted, from which upper limit a membrane piercing element extends internally. On the inner side surface of the lid a retaining ring is obtained which, in the closed configuration of the bottle package, is engaged by activation in a corresponding ring-shaped groove defined on the outer side surface of the neck, so as to retaining the piercing element at a height above that of the membrane that closes the dispensing nozzle. At the time of use, the cap fits on the neck of the container body until the retaining ring disengages from the corresponding slot and the piercing element tears the membrane and opens the dispensing nozzle, after which the cap is removed from the container. neck to allow the assortment of the product. In addition, the container body has a pair of gripping fins that extend, in a diametrically opposite direction to each other, from its outer side surface. Known bottles can be produced in individual units or interlaced with others in series (bands); in the latter case, the gripping fins of the container bodies of two successive bottles are temporarily joined together with the pre-breaking lines. However, these bottles are not susceptible to improvement, in particular in order to avoid a potentially harmful use of the product they contain.

In particular, the known bottles are without adequate safety means to avoid, or at least make it less easy, the opening of the dispensing nozzle and the removal of the lid by children, who can ingest the product inside the bottles in a incorrect way, which is obviously risky for your health. Said bottles, moreover, do not show in a clear manner and that any alteration and / or that have been opened inadvertently, and that does not ensure the integrity and sterility of the product they contain, is immediately perceived. In fact it can happen that the bottles, handled or placed in storage units (drawers, wardrobes, utility boxes, etc.), are subjected to blows such as pushing their lid on the neck until the piercing element tears the membrane before it the product is actually used, the obstacle provided by the coupling between the retaining ring and the corresponding ring-shaped groove are often not sufficient to counter such shocks. To overcome these drawbacks, at least in part, it is known that the bottles comprise a pair of seal fins that extend from the container body in diametrically opposite directions, located between the grip flaps and the lid and attached, removable by ripping, with the body, with the grip fins or with the cover along the respective weakened areas.

When the bottle is used, when the lid is rotated, the aforementioned weakened areas are broken, showing that the opening has occurred. Nevertheless, bottles without the aforementioned safety means are adequate to avoid, or at least make opening for children easier. A different type of bottles for fluid products is made in an individual body piece wherein, the body containing the product is formed together with closure means in a single body without any interruption at all. The closure means are connected to the body by means of deformable and breakable elements that act as safety seals; the deformations and / or ruptures of the previous elements are signs of alteration. However, the manufacture of these different types of bottles in an individual body part requires complex manufacturing processes and high production costs.

OBJECTIVES OF THE INVENTION The main objective of the present invention is to provide an improved bottle for fluid products, particularly pharmaceutical, medicinal or cosmetic products, which provide requirements for minimum security adequate to avoid or in any case restrict the potentially harmful use of the products contained in it. Within this technical objective, another objective of the present invention is to ensure the integrity and sterility of the products packaged inside the bottles. Another objective of the invention is to make it possible to observe that the bottles have been opened, in a clear and immediate manner. Another object of the invention is to satisfy the above objectives with a simple structure, with a relatively practical implementation, safe to use and with effective operation, as well as having a relatively low cost. The aforementioned objects are all achieved by means of this improved bottle for fluid products, particularly pharmaceutical, medicinal and cosmetic products, comprising a container body for containing a fluid product, particularly a pharmaceutical, medicinal or cosmetic product, a dispensing nozzle of said product. product defined at one end of said container body, a tear-off membrane for closing said dispenser nozzle, a closure element that can be screwed or unscrewed at said end of the container body and provided as a cap within which at least one perforator is defined. said membrane, characterized in that it comprises maintenance means for maintaining said lid in a safety configuration, wherein said perforator is placed substantially away from said membrane and wherein said cap can rotate freely about the axis for screwing and unscrewing said closure element in at least one direction of rotation.

DETAILED DESCRIPTION OF THE INVENTION With special reference to said figures, an improved bottle for fluid products, particularly pharmaceutical, medicinal or cosmetic products, has been designated globally with the reference number 1. The bottle 1 comprises a container body 2 of a fluid product (pharmaceutical, medicinal or cosmetic), which is substantially cylindrical and elongated and extends at one end in a neck 3, in the upper part of which a product dispensing nozzle 4 is defined. A closure element 5 is connected by screwing and unscrewing with the neck 3, and has a lid 6, inside which is defined a perforator 7 of a closing membrane 8 integrated with the outer edge of the dispensing nozzle 4. The membrane 8 can, for example, be made from a disc of polymeric material integrated with the container body 2 during the last pressure phase. In a useful manner, the bottle 1 comprises maintenance means for maintaining the lid 6 in a safety configuration, wherein the perforator 7 is positioned substantially away from the membrane 8 and wherein the lid 6 can rotate freely around the screw axis and unscrewing the closing element 5. In a first embodiment of the invention, shown in figures 1, 2 and 3, the closing element 5 comprises a plug 9 inside the lid 5, the perforator 7 extends from the upper limit of the plug 9 inside it and towards the dispensing nozzle 4. Adjusting threaded means to allow the screw 9 to be screwed and unscrewed to the neck 3 which is formed of a screw 10 defined on an outer side surface of the neck 3, and a corresponding nut 11 defined on the inner side surface of the plug 9. The lid 6 fits over the plug 9 and is related to it by sliding between the previous safety configuration, shown in figure 2, and a working configuration, shown in figure 3, wherein the lid 6 becomes integral with plug 9 when placing the coupling means between them. Said coupling means may include, for example, one or more protrusions 12 defined on the outer surface of the cap 9, near the lower edge, and suitable for inserting into respective slots 13 defined longitudinally on the inner surface of the cap 6. Once the lid 6 has been moved to the working configuration, after insertion of the projections 12 into the slots 13, relative rotation between the plug 9 and the lid 6 is avoided. Alternatively, different types of media can be used. Couplings can be provided in which the protrusions and relevant grooves are formed and distributed differently in the plug 9 and in the lid 6. The above maintenance means for maintaining the lid 6 in the safety configuration can be of the media type elastic 14 which acts in contrast to the movement of the lid 6 from the configuration Security to work configuration. In particular, said elastic means 14 are made from a plurality of leaf springs fixed to the inner surface of the lid 6, at the upper limit, and which are coupled by bending on the outer surface of the plug 9, in an upper portion. substantially conical 15 and with a cross section substantially deviating towards the container body 2. Usefully, the bottle 1 may comprise a first defined retaining ring 16 extending from the outer surface and the plug 9, and a second retaining ring 17 defined extending on the inner side base of the lid 6. The first and second retaining rings 16 and 17 are suitable for coupling to prevent the lid 6 and the plug 9 from moving away from each other in the safety configuration. In a useful manner, the bottle 1 comprises a sealing collar 18 which fits coaxially into the neck 3 and is placed, removable by tearing, between the container body 2 and the closure element 5. In particular, the upper surface of the collar seal 18 relates to the lower portion of the plug 9 along the first weakened areas 19, of the type of pre-established break line. Generally, the bottle 1 comprises a ring-shaped ridge 30 defined extending from the outer surface of the neck 3, below the closure element 5, and suitable for retaining the sealing collar 18 around the container body 2 after its detachment from the plug 9. However, the conformations and different arrangements of the ring-shaped edge 30 can not be inappropriate. In a second embodiment of the invention, shown in figures 4, 5 , 6 and 7, the closure element 5 consists of a cover 6, fitted directly on the neck 3. The perforator 7 is defined extending from the upper limit of the cover 6, inside it and towards the dispensing nozzle 4. maintenance means for maintaining the cover 6 in the security configuration comprises a first retaining element 20, of the first type of ring-shaped tooth which is defined to extend from the side surface of the neck 3, which is engaged with a blocking element corresponding 21, of the ring-shaped groove type, which is defined on the inner side surface of the lid 6. In particular, the adjustment of the first ring-shaped tooth 20 within the groove In the form of a ring 21, it is possible to lock the cover 6 in the safety configuration. The product 1 also comprises a second retaining element 22, which consists of a second ring-shaped tooth extending from the lateral surface of the neck 3 below the first ring-shaped tooth 20.

In a useful manner, in the working configuration, with the cover 6 further fitted on the neck 3, the second ring-shaped tooth 22 fits inside the ring-shaped groove 21. The bottle 1 comprises threaded means which, in the working configuration allow the cover 6 to be screwed and unscrewed to the neck 3. The threaded means are formed of a screw 23 defined on the outer side surface of the neck 3, and of a corresponding nut 24 defined on the inner side surface of the 6. In a useful manner, in the safety configuration, the screw 23 and the screw nut 24 are set apart. Similarly to the first embodiment illustrated above, the bottle 1 comprises a sealing collar 18 fitted coaxially to the neck 3 and placed, removable by tearing, between the container body 2 and the closure element 5. In particular, the upper surface of the sealing collar 18 is related to the lower portion of the lid 6 along the first weakened areas 19, of the type of pre-established breaking line. The bottle 1 also comprises a pair of grip flaps 25 extending from the container body 2 along diametrically opposite directions. With reference to both the first and second modes, as shown in Figures 1 and 4, several bottles 1 can be related with another in the grip flaps 25 and by interposing the second weakened areas 26, of the type of pre-established break line or the like. In a useful manner, the caps 6 of the bottles 1 can be adjusted with an operation key 27 suitable to make the fastening easier for a user, which can be formed of a band substantially coated around the lid 6, and integral with it ( Figures 1-3) or, alternatively, by a pair of operation fins, each diametrically opposite to the other, and defined extending from the outer lateral surface of the cover 6 (Figures 4-5). In a useful manner, the operation keys 27 of the lids 6 of the bottles 1, one against the other, can be related to interposing the third weakened areas 28, of the type of pre-established break line or the like. At the end of the container body 2 opposite the neck 3 an opening 29 is defined through which, during the packaging phase of the bottle, the product is introduced; after filling the opening 29 is closed, for example by sealing its edges. The operation of the invention is as follows. With particular reference to the first embodiment of the invention, shown in figures 1, 2 and 3, before using the bottle 1 is in the security configuration (figure 2). After the bottle 1 has been removed from the band, which is shown in figure 1, the lid 6 is further fitted on the neck 3 by means of a pressing action and slides from the safety configuration to the working configuration, in contrast to the action with the leaf springs 14. In said working configuration, the projections 12 are adjusted in their respective grooves 3 and a twisting action in the cover 6 causes the integral rotation of the plug 9 , by screwing the plug 9 by itself into the neck 3 and the movement of the perforator 7 near the dispensing nozzle 4, until the contact and rupture of the membrane 8 (figure 3). During the sliding of the lid 6 from the safety configuration to the working configuration the lower edge of the lid 6 engages on the upper surface of the sealing collar 18, causing the breaking of the first weakened areas 19 and the falling of the collar of sealing 18 below the ring-shaped edge 30. The ring-shaped edge 30 retains the sealing collar 18 around the container body 2 during the subsequent stages of use of the bottle 1. A twisting action of unscrewing in step 6, always diminished in the working configuration, allows the removal of all the closing element 5 of the neck 3, thus releasing the dispensing nozzle 4 and allowing the use of the product inside the counter body 2. With particular reference to the second embodiment of the invention shown in figures 4-7, before using the bottle 1 this is in the security configuration (figure 5).

After the bottle 1 has been removed from the band, shown in Figure 4, the lid 6 is further fitted on the neck 3 by means of a pressing action and slides from the safety configuration to the working configuration, with the decoupling of the first ring-shaped tooth 20 from the ring-shaped groove 21. In said working configuration, the screw 23 is adjusted in the nut screw 24 and the twisting action of the screw 6 in the cover 6 causes the perforator 7 moves near the dispensing nozzle 4 to the contact and rupture of the membrane 8 (figure 6). A subsequent twisting action in the direction of unscrewing in the operation key 27 allows the cover 6 of the neck 3 to be removed, thus releasing the dispensing nozzle 4 and allowing the use of the product inside the container body 2 (Figure 7). During the unscrewing for the removal of the cover 6, the upper edge of the sealing collar 18 engages the lower surface of the second ring-shaped tooth 22, causing the breaking of the first weakened areas 19 and the detachment of the sealing collar 18. The second ring-shaped tooth 22 retains the sealing collar 18 around the container body 2 during the subsequent steps of using the bottle 1. It has been found in practice how the described invention achieves the proposed objectives and in particular the highlighting the particular conformation of the closure element and the presence of the means of maintenance in the security configuration ensure adequate security requirements to avoid or in any case restrict a potentially harmful use of the products contained in it. In fact to open the bottle, pressure must be exerted on the lid to change from the safety configuration to the working configuration, something that makes the opening less immediate and thus protects the children, or in general, the people who they may inappropriately use the products contained in it and that it allows to restrict, at the same time, the opportunities of accidentally opening the bottle. A further advantage of the invention consists in the presence of the sealing collar which provides a clear and rapid indication that the bottle has been opened. The invention thus conceived is susceptible to numerous modifications and variations, all within the scope of the inventive concept. In addition, all the details can be replaced by other elements that are technically equivalent. In practice, the contingent shapes and dimensions may be any in accordance with the requirements without departing from the scope of protection of the following claims.
