Abstract

Stopper with container for a desiccator for use in vessels basically comprising a main part (1) that integrates a body (2) and a desiccator container (3) obtained from a single injection mould, with a seal (4) independent of the aforementioned elements provided with a mouth (5) that is inserted by pressure in the body (2) with the aid of a crown of uniformly spaced protrusions (6) inside the body (2), which delimit on the bottom a band (8) in which said mouth (5) is housed.

Description

    OBJECT OF THE INVENTION
  • The present invention relates to a stopper of the type that incorporate a container with a desiccator, applicable in vessels generally used in pharmaceutics, in which the desiccator prevents humidity from entering the vessel.
  • The object of the invention is a stopper comprised of two parts: a main part that integrates the body of the stopper and the container with the desiccator; and another part consisting of the safety seal. The two parts are independent and have means for simplifying their assembly, the main part being conceived with different shapes and heights for application in different vessels, yet maintaining the same diameter for attaching it to the same type of seal.
    • BACKGROUND OF THE INVENTION
  • Stoppers incorporating desiccators are preferably used in pharmaceutical applications to prevent humidity from entering the vessel. This is the case in vessels containing products in powder form, in which the humidity is absorbed by the desiccator preventing the powder product from compacting with time.
  • The desiccator is held in a container that is normally attached as an independent element in a housing established for such purpose in the body of the stopper. On another hand, the stopper is completed by a safety seal conceived to guarantee the tamper-proof conditions of the vessel.
  • Thus, the stopper generally comprises three independent parts: body, container and seal; which require three different moulds for manufacturing them with the corresponding cost implications, as well as requiring a proper assembly and fit for their correct inclusion in the vessel.
  • The holder of the present invention also holds Spanish Utility Model with application number 200300723, which proposes the use of a single mould to obtain a one-part stopper integrating the aforementioned components in order to reduce manufacturing costs. However, the use of this one-part stopper is limited to certain vessels, as when a stopper with a different height and shape is required for a different vessel an entirely new mould must be manufactured.
  • As the seals used in all stoppers are basically the same, as opposed to the stopper body which as an identification element of the stopper varies in design and height with the vessel in which it is used, the need arises to use a single mould for the seal and to change the body of the stopper with a container, maintaining the approach of minimising the moulds used to manufacture stoppers, which is the object of the invention described below.
    • DESCRIPTION OF THE INVENTION
  • The stopper with a container for a desiccator disclosed in this invention entirely fulfils the expectations described above, mainly comprising a stopper body comprising a container with a desiccator, preferably silica-gel, conceived as a single main part obtained from a mould with a shape according to the part to be obtained, and an independent seal obtained from a universal mould, on which the stopper body is coupled by pressure.
  • The seal conceived in this manner will be mass-produced, ensuring its use in any type of vessel on which will also be attached a main part with a variable shape and size but the same external diameter as the mouth of the seal.
  • Thus, the stopper comprises two parts, the main part consisting of the body and the container, being provided with means for coupling by pressure on the other part, which consists of the seal.
  • The main part incorporates an outer wall on which a thread is provided that matches the thread made in the neck of the vessel and an inner wall concentrically with the outer wall that internally defines a compartment that constitutes the container for the desiccator.
  • The means described for coupling the body on the seal consist of a crown of uniformly spaced protrusions on the inside and on the base of the outer wall, delimiting on the bottom a band in which is housed the upper mouth of the seal after it is inserted under pressure and the crown of protrusions has been overcome.
  • The seal, along the entire perimeter of its mouth, has a slight inwardly-converging slope that facilitates the gradual displacement of its outer face in contact with the protrusions during the assembly by pressure of the stopper body and seal, until overcoming them so that the mouth is left at the aforementioned band of the stopper body.
  • From said mouth, the seal is extended on the bottom by a wall interrupted by a horizontal weakened line in which uniformly distributed breakable points are disposed which, once broken by turning the stopper body with respect to the vessel seal, will break this seal.
    • DESCRIPTION OF THE DRAWINGS
  • To complete the description being made and in order to aid a better understanding of the characteristics of the invention, according to a preferred example of embodiment, a set of drawings is accompanied forming an integral part of the description where, for purposes of illustration only and in a non-limiting sense the following is shown:
    • Figure 1.- Shows an exploded view of the stopper object of this invention representing the main part composed of the body and container for desiccator and another part consisting of the seal.
    • Figure 2.- Shows a cross-section side view of the two parts before they are attached to each other.
    • Figure 3.- Shows a cross-section side view of the stopper with the two parts attached to each other.
    • Figure 4.- Shows a perspective view of the main part from below, showing the crown of protrusions of the stopper body.
    PREFERRED EMBODIMENT OF THE INVENTION
  • The stopper with container for desiccator constituting the object of this invention is used to seal the vessel on which it is screwed, to make it tamper-proof and to prevent humidity from entering it, mainly consisting of a main part (1) comprised of a body (2) and a desiccator container (3) obtained from a single mould and another part consisting of an independent seal (4), which is provided with a mouth (5) that is inserted by pressure and is attached to the stopper body (2) with the aid of coupling means defined in the body (2).
  • The coupling means of the body (2) consist of a crown of uniformly spaced protrusions (6) inside and on the base of an external wall (7) of the body (2), which delimit on the bottom a band (8) in which the mouth (5) of the seal (4) is housed with a slightly converging slope after it is inserted by pressure overcoming the crown of protrusions (6).
  • Below the mouth (5) of the seal extends a wall (9) provided with a horizontal weakened line (10) with breakable points (11) that are broken when the seal of the vessel is broken.
