Description
SPECIFICATION
Container for Storing and Direct Application of
Liquids and Pastes
This invention relates to a container for the storage and direct application of liquids and pastes of the kind comprising a hollow body with a tapered dispensing nozzle at one end and an open opposite and filling end which is closed by a plug. The container is also provided with a cover cap which can be fitted over the dispensing end and held by, for example, a snap-on screw fastening. Containers of this type, see for instance
German Gebrauchsmuster specification No. 7 732 972, are used for example to contain adhesives and sealants and for technical liquids, pharmaceuticals, aromatic oils, and so on.
The closure plug is, in practice, pressed into the open end of the container body after the introduction of the contents, and as a consequence the contents of the container are under pressure and this has the effect that when the liquid or paste is first used it tends to spray out of the dispensing nozzle. In the case of particularly active products, for example adhesives with a cyanacrylate base or etching liquids this is extremely unpleasant. A further disadvantage lies in the fact that the dispensing nozzle, after being opened, is quickly closed again by contamination or gumming and further use is no longer possible or the contents of the container dry out. Again, when the dispensing nozzle is opened by tearing part of it away, the tearing constricts to an indefinite degree the dispensing opening at the point of fracture, or even completely closes it.
In addition to the type of container disclosed in
Gebrauchsmuster specification 7 732 972 containers have long been in use which have nozzles which have to be prepared for use by a separately-available needle or by cutting with a knife. The needle can serve at the same time as a closure for the nozzle. This however only works when the content of the pack does not harden around the needle. In the case of cyanacrylate adhesive however this as a rule happens, so that it is impossible to pull the needle out of the nozzle at a later time.
The object of the present invention is to provide a container of the kind set forth above of a construction which is such as to avoid the defects set forth.
This object is met by the present invention by providing a container for storage and direct application of liquids and pastes, comprising a body which is tapered at one end to form a dispensing nozzle and is open at the other end where it is adapted to receive a closure plug and is flanged over the edge of said plug to engage the latter in sealing fashion, and a cover cap adapted to be disposed on and connected to said tapered end, said closure plug being provided at its periphery with venting slots for the passage of air when the plug is pushed into the open end of the container body.
The invention has the substantial advantage that there is no excess pressure in the interior of the container as a result of the closure thereof so that there is no danger for the liquid or paste to squirt out when it is opened. Further there is no danger of the contents of the container drying out or the dispensing nozzle being gummed up in such a way as to make the container useiess.
Advantageously the closure plug has a depending skirt around which the end of the container body defining the opening in the latter is turned over and sealed, and the venting slots are disposed labyrinth-fashion in said end and skirts.
By a further feature of the invention the dispensing nozzle is cupped at its leading end to form a drip tip, this cup being defined by a membrane, and the cover cap is provided externally with a tapered recess housing an axially disposed needle whereby, on removal of the cap from its cover and guard position at the leading end of the container body it can be reversed and replaced on this end so that the said recess is fitted over the dispensing nozzle and the needle perforates the membrane to form a dispensing opening. This gives the additional advantage that the needle provides a definite opening for ready application of the liquid or paste in the form of drops or as a string. An already opened and possibly stoppered or gummed nozzle can be reperforated by means of the needle. After the opening of the container a sealed closure of the nozzle is possible.The seating of the cap in combination with the snapping down or screwthreaded connection provides an additional sealed effect.
Conveniently the cover cap is provided internally with a stopper for engagement with the dispensing nozzle to close any dispensing opening provided in the tip of the latter, and with guide ribs for sliding engagement with the periphery of the dispensing nozzle for centering the cover cap.
Further it is advantageous that the plug is hollow and is filled and closed with an auxiliary package, or for example a moisture-absorbent mass.
In an advantageous method of making a container according to this invention the body of the container is made by injection moulding from a plastics material, for example poiyethylene, polypropylene, or the like, and in assembly the closure plug is pressed into the open end of the container body, the marginal edge of this open end is completely flanged over an end rim of the plug, and the flanged-over edge is welded to this rim to provide an airtight closure.
The invention will be explained in more detail in the following description with reference to examples of embodiment which are illustrated in the drawings. In these drawings:
Figure 1 is an elevational view of a container of this invention with a cover cap, with part in section,
Figure 2 is a longitudinal section on an enlarged scale through the leading part of the container with its dispensing nozzle.
Figure 3 is a longitudinal section through the base end of the container on a further enlarged scale,
Figure 4 is a front view enlarged yet again of the closure plug seen in Figure 3,
Figure 5 is a side view of the closure plug in a container of circular cross section,
Figure 6 is an enlarged sectional view of part of the closure cap placed on the dispensing nozzle of the container, and
Figure 7 shows a further constructional form of the container end, this being a detail in longitudinal section at the part encircled at A in
Figure 1.
The container 1 illustrated in Figure 1 may represent a mini pack with a content of say 0.5 cm3 up to a large pack with a content of about 1000 cm3. The body of the container is cylindrical at its medial and lower parts but tapers at its leading end to form a conical dispensing nozzle 2.
The body could instead be of oval or polygonal cross section.
The dispensing nozzle 2 is provided with a cover cap 3 with a snap-on or screw threaded fit.
It will be noted that in the case illustrated an annular groove 9, or it could be a screw thread, is arranged in the body inwards of the conical end.
At its tip the dispensing nozzle is formed with a cupped recess 6 closed by a perforable membrane 7 and it will be observed that the cover cap 3 (see Figure 1) is formed at its leading end with a recess 4 of a taper corresponding to that of the tip of the dispensing nozzle 2. This recess 4 houses an axial pin 8 secured in the cap.
Thus, when the cap is removed from the assembly it can be reversed and the recess 4 fitted over the nozzle tip and pressed down so that the pin 8 pierces the membrane 7 to form a positivelydefined dispensing opening in the tip. This allows for application of the contents of the container in drops, by virtue of the cup 6, or as a string.
The container body is initially open at the end remote from the nozzle 2 and is here provided with a skirt 11. It is fitted through this open end which is then closed by a plug 5, which is pressed in. The closure plug 5 is substantially of U-form in cross section, there being a step 10 to define the pushed-in position. In this position (Figure 3) the skirt 11 of the container body stands a littie proud of and is turned over inwardly so that it completely encloses the rim 12 of the plug 5. The flanged-over skirt 11 of the container body is then sealed to the rim 12 of the plug 5.
Figure 4 and 5 show that venting slots 13, 14 are provided along the periphery, that is to say parallel to the axis of the container and partially on the periphery of the plug 5, preferably labyrinthically offset relatively to one another.
Thus in insertion of the plug 5 into the container 3 the excess pressure can be vented and thereby after the edge 11 has been flanged over the edge
12 there is an absolute seal in conjunction with the welding process.
The hollow plug 5 may be filled with a moisture-absorbing mass 1 8 and sealed against the exterior with the assistance of a small plate 1 5 as illustrated in Figure 7. Instead of using a moisture-absorbent mass 1 8 an auxiliary filler may be provided in the case of packs of larger diameter, for an example an auxiliary product or a service aid.
Figure 6 shows on a larger scale a particular construction of cover cap 3 having therein a small central closure stopper 1 6 which penetrates under pressure into the cup cavity 6 defining the drip tip of the dispensing nozzle 2 during the dnapping-down of the cover cap. For centering purposes use is made of internal ribs 1 7 in the cap which slide over the dispensing nozzle 2. The result is that after the opening of the container by perforations of the membrane 7 the contents can be resealed against the exterior and gumming up of the opening avoided.
