Abstract

IT INCLUDES A BODY 1 IN SYNTHETIC OR ANALOGUE RESIN, AN INTERNAL CAP 5, FIXED TO THE OUTLET 2 OF THE CONTAINER AND INCLUDING A CAP 4 DIRECTED UPWARD, BORED WITH 3 HOLES IN ITS SIDE WALL, A RUBBER PIPE ON THE TOP 6 CAP TO CLOSE HOLES 3 AND AN EXTERIOR CAP 8 SURROUNDING PIPE 6 AND PRESENTING IN ITS BOTTOM INSIDE PART A SHOULDER 9 WHICH PUSHES THE LOWER INSIDE PART OF PIPE 6 AGAINST THE 5 'BASE OF HAT 5 AND PRESENT AT THE CENTER OF ITS WALL UPPER A LIQUID OUTLET HOLE 7. THIS STRUCTURE PREVENTS THE LIQUID FROM RETURNING INTO THE CONTAINER AND IMPURE AIR OR CONTAMINATED SUBSTANCES FROM ENTERING THE CONTAINER.

Description

The present invention relates to a container for Alleviating

  by pressure, for liquid for medical use and, more particularly

  firstly, such a container of simple and effective structure which is able to pocket liquid pushed by pressure out of the container to flow back inside the container, as well as

  prohibit the entry into the container of atmospheric air

  as impure and contaminated substances.

  The most important point for a container with

  pressure knot that contains a liquid for medical use

  and press to eject the desired amount of

  it contains, is to be sufficiently tightly sealed to prevent the liquid for medical use it contains to escape, even if we leave the container in any posture, and have the desired structure to prevent that liquid for medical use ejected by pressure of the container does not

  within the latter and that foreign substances

  by penetrating the container, contaminate

  the liquid that is contained in it.

  containers which can be ejected by pressing the desired quantity of liquid and which prevent leakage of liquid contained even if the container remains lying, but without being subjected to pressure. One of these common containers comprises a

  valve body disposed in its opening and two mortars

  thin elastic skin that are usually

  folded against each other to close the opening of the

  when pressing the container, these two pieces of

  film are separated from each other by the effect of

  in the container, to let the liquid

  kept out of the container, but when you stop pressing the

  container, they come into contact with each other to

  By opening the container, this valve body is a molded element or composed of two separate films in contact with each other.

  many improvements remain to be made to improve the

  the operation and reduce the cost of this part of the

cipient.

  The present invention aims to propose a recipe

  liquid for medical use comprising a container body made of synthetic resin or the like and which contains a liquid for medical use, a fixed inner cap

  at an opening of the container body and having a cap

  the hollow is directed upwards, pierced with holes in its side wall, a rubber hose fitted hermetically on the hollow cap of the inner cap to close the holes, and an outer cap disposed externally to the rubber hose and comprising, in its part an inner shoulder, a shoulder for urging and securing the inner lower portion of the rubber hose against the base of the inner cap and drilled, in the center of its upper wall, with a hole through which the liquid for medical use contained therein

  container being remarkable in that once out of the container

  the liquid can not flow back into this last

  deny and that the penetration into the container of atmospheric air

  impure pheromite and contaminated substances is prohibited.

  The present invention therefore aims to propose a

  pressure-operated container for liquid for use

  dical: which is able to prohibit the reflux into the container of liquid for medical use as well as the penetration into the container of atmospheric air, foreign bodies and the like; which is capable of attenuating the force of ejection of medical liquid from the container so that this liquid is gently projected onto the objective, which makes it possible to operate

  gentle cleaning with the liquid spray or injection

  of the latter; that it is economically feasible to achieve good results by using the commercially available rubber hose which forms the valve-acting part; that can be achieved in a simple manner through the use of the usual commercially available rubber hose which forms the valve-acting part; which can easily be assembled by using the usual rubber hose, available in the

  commerce, which forms the part acting as a valve.

  these goals, as well as others, are achieved through

  structure and the operating mode of the container for

  medical device according to the present invention, a preferred embodiment of which will now be described by way of non-limiting example, with reference to the accompanying drawing, in which: FIG. 1 is a front view illustrating an example of liquid container for medical use according to the present invention;

  FIG. 2 is, on a larger scale, a sectional view of

  pe along the line II-II of Figure 1; FIG. 3 is a sectional view similar to FIG. 2

  and shows the state of the container according to FIG.

  the liquid for medical use it contains.

  As shown in FIGS. 1 and 2, a container for liquid for medical use A according to the present invention comprises a body 1 intended to contain a liquid for use

  medical and made of synthetic resin or the like,

  both a thin wall and an inner cap 5, with relatively high elasticity, attached to an opening 2 of the container 1 and having a hollow cap 4 directed downwards and pierced with through holes 3 in its side wall, a rubber pipe 6 hermetically fitted on the cap 4 and a

  outer cap 8 disposed outside the rubber hose

  6 and having, in its lower inner portion, a shoulder 9 for pushing and securing the inner lower portion 6 'of the rubber hose 6 against the base 5' of the

  inner hat 5 and also, in the center of its upper wall

  re, a through hole 7 through which said liquid is expelled externally We see in 10 an appendage to break with a sharp blow,

  protruding on the center of the upper wall of the ex-

The elastic hose 6 used comes from a long commercial elastic hose with a determined diameter, in which a section of length required This solution is extremely inexpensive In addition, the attachment of this section of the pipe in

  rubber 6 on the cap 4 is easily effected by

When pressing the wall of the container 1 containing a liquid for medical use m, such as contact lens cleaning liquid or liquid for enemas for example, the liquid m content passes through the holes 3 drilled in the side wall of the cap 4 the inner cap 5, passes between the cap 4 and the rubber hose 6, deviating by forced spreading of the cap 4 to join by paths

  This liquid ejected m 'is not driven in a straight line of the container 1 but first discharged laterally through the holes 3, then goes to the hole 7 along the side wall of the cap 4 against the resistance exerted inwardly by the rubber hose 6 Therefore,

  To prevent the entry of impure atmospheric air or liquid ejected into the container, the contents of which would be
