Description

A PACK OF MORTAR This invention relates to a pack of mortar.
Mortar is extensively used in the building industry, for example in brick laying. The mortar is traditionally made up on site and, once the mortar is made up, it has to be used immediately. Mortar that is not used immediately quickly loses its workability and starts to set, whereupon it cannot be used. The unused mortar represents wastage and, in addition, it is often not convenient to dispose of the unused mortar especially if it is in a large quantity. The mixing of the mortar on site may also present something of a problem.
More specifically, an appropriate flat mixing area may not be immediately available, and it may be generally inconvenient to have to mix the mortar prior to being able to use it.
It is an aim of the present invention to reduce the above mentioned problems.
Accordingly, in one non-limiting embodiment of the invention, there is provided a pack of mortar, which pack comprises a container provided with mortar, the mortar being wet and ready for use, the amount of mortar in the container being such that the container has an unfilled space above the mortar, and the container being a sealed container which is made of a flexible material whereby the mortar can be kneaded in the container using the unfilled space in order to give the mortar a final mix prior to opening of the container.
With the pack of mortar of the present invention, the mortar is able to be made up in a factory such that it is perfectly mixed and in a perfect condition. Because the container is sealed, the mortar has an extended use life. Thus, for example, traditionally produced mortar on a building site tends to set in a matter of hours whereas, with the mortar in the sealed container, the mortar may have a use life of up to 10 days. If during storage and/transportation of the pack of mortar, water tends to separate out and lie on top of the mortar in the container, then the mortar may be given a final mix prior to opening the container simply by kneading the container using the unfilled space in the container. The unfilled space should obviously be sufficient to enable this kneading.The kneading can simply be effected by upending the pack of mortar several times and/or pushing the sides of the container. Only minimal kneading will normally be required and then the mortar will be in a good condition for use. Because the mortar can be produced in a factory, it can always be of a correct designation and it can always be of a totally consistent quality. Persons wishing to use the mortar basically merely have to open up the container and there are none of the previous problems associated with finding a convenient place to mix the mortar. In addition, a person buying a pack of mortar in accordance with the present invention need not use the mortar immediately and the person may wait for a convenient time.Thus, in the event that weather conditions should be inclement, then a person who has bought the pack of mortar can wait for a few hours or a few days until weather conditions improve or until it is generally more convenient to that person to use the mortar. When used at any time during its working life, the mortar will harden like a conventional mortar. After use, the container can simply be disposed of and there will be no messy mortar making up site to wash down.
Preferably, the container is made of a plastics material. Other water resistant materials may however be employed such for example as paper or paper laminates, if appropriately lined with a water resistant material.
Preferably, the container is sealed by being heat sealed. The heat seal may simply extend as a horizontal line across a top part of the container.
Other types of sealing methods may be employed for sealing the container.
Advantageously, the pack of mortar is one in which the container has a hand grip portion for use in lifting the container, the hand grip portion being formed by flexible material of the container provided above the seal in the container.
The container may be of any suitable and appropriate size. Thus, for example, the container may be in the form of a large sack-sized bag for industrial use. Alternatively, the container may be in the form of a small hand-holdable bag for individual use by persons doing their own building works.
The mortar may be of any known and currently used composition. The mortar will usually be such that it has a cement and sand base. Lime may be added as may be appropriate if a cement/sand/lime mortar base is required.
Advantageously, the mortar includes an air entraining admixture. The air entraining admixture is used to entrain a controlled quantity of small air bubbles into the mortar. The small air bubbles help to improve the cohesion and workability of the mortar. In addition, the small air bubbles may improve the durability of the mortar when the mortar has set. In some harsh retarded mortars, segregation of the mortar mix may tend to occur and in this case the air entraining admixture may help to stabilise the mortar. The air entraining admixture may advantageously be that sold under the Trade Mark CEBEX 706 or CONPLAST.
The mortar may also include a plasticiser and retarding liquid admixture. Such an admixture may be especially desirable for use with mortars containing high levels of fine materials, for example lime or clay silt. The plasticiser and retarding liquid admixture may be that sold under the Trade Mark CE3EX 311.
An embodiment of the invention will now be described solely by way of example and with reference to the accompanying drawing which shows a pack of mortar.
Referring to the drawing, there is shown a pack 2 of mortar, which pack 2 comprises a container 4 provided with mortar 6. The mortar 6 is wet and ready for use. As can be seen from the drawing, the amount of mortar 6 in the container 4 is such that the container 4 has an unfilled space 8 above the mortar 6.
The container 4 is a sealed container which is made of a flexible material in the form of transparent plastics material. Because the container material is flexible, the mortar 6 can be kneaded in the container 4 whilst the container 4 is still sealed. This is permitted by using the space 8. Thus the mortar 6 can be kneaded in the space 8 by pushing on the sides of the container 4 or simply by upending the container 4 several times. When the container 4 is upended, it will be apparent that the space 8 will always transfer to the uppermost end of the container 4. The kneading can be employed to give the mortar 6 a final mix prior to opening of the container 4. This is advantageous in ensuring that the mortar is always in a perfect condition ready for use at the time of opening the container 4. If, during storage and/or transport, water from the mortar 6 has tended to separate out and lie on top of the mortar 6, then this can easily be mixed back in with the mortar simply by kneading the mortar as mentioned above.
The pack 2 can very conveniently be taken right up to an actual workplace, and this may be especially advantages for workplaces above ground level. There is no need to find a flat piece of ground or a large piece of board on which to mix the mortar 6. After use, the empty container 4 can simply be disposed of and there is no messy clearing up as often occurs with mortar as traditionally mixed on site.
The container 4 is sealed by means of a heat seal line 10. The heat seal line 10 is not positioned at the top of the container 4 as can be seen from the drawing. Excess material 4 is provided above the heat seal line 10 and this excess material provides a hand grip portion 12 for enabling the container 4 to be lifted. The hand grip portion 12 may thus be advantageous in enabling the pack 2 to be carried to a workplace, or alternatively to be upended for kneading purposes.
The pack 2 is easily formed. The mortar may be mixed in a factory or wherever desired and appropriate.
The mortar will usually be mixed in a machine but it may be hand mixed if desired. The mortar is then placed in the container 4 whilst the container 4 is in an open condition. It is only then necessary to seal the container 4 in order to produce the completed pack 2.
The illustrated container 4 is a relatively large sack-type container and such a container 4 may advantageously be held at its upper neck portion whilst it is being filled with mortar 6 from a mixing machine (not shown). The filled container 4 can then be passed to a sealing machine. The sealing machine may squeeze the open sides of the container 4 together whereupon the heat seal line 10 may be effected by a pair of heat sealing electrodes. The electrodes will contact the container 4 just for a sufficient time to form the heat seal line 10, it being necessary not to allow the electrodes to remain too long in contact with the container 4 as otherwise the electrodes will cause the plastics material of the container 4 to burn away instead of to heat seal. The sides of the container 4 may be closed by foot pedal operated jaws.The squeezing of the sides of the container 4 may advantageously be done such that the mortar 6 in the container 4 is also squeezed. This acts to squeeze air out of the bag below the heat seal line 10 to be formed. When the heat seal line 10 is formed and the sides of the container 4 are no longer being squeezed towards each other, the mortar 6 runs back to the position shown in the drawing but then the space 8 contains a partial vacuum rather than being filled up with air. This helps to ensure that the pack 2 is easily movable and it also helps to ensure that the flexible material of the container 4 adjacent the space 8 is less prone to puncturing during storage and transport than it would be if the space 8 were a bulging space 8 having a lot of air in it.
It is to be appreciated that the embodiment of the invention described above with reference to the accompanying drawing has been given by way of example only and that modifications may be effected. Thus, for example, the container 4 may be of any suitable and desired size and shape. The container 4 may be sealed with a sealing means other than the heat seal line 10.
Instead of being formed of a transparent plastics material, the container 4 can be formed of a nontransparent plastics material or a flexible water resistant material other than a plastics material. The mortar may be of a wide variety of different specific compositions, and the mortar may be non-coloured or coloured with appropriate pigments as may be desired.
Where admixtures are used to entrain air and/or retard the initial setting of the mortar, then these admixtures will preferably be such as to be non- aggressive to metals which may be embedded in the mortar during use of the mortar. The entrained air will also help to reduce the risk of mortar failure from frost attack.
