Definitions
- the invention is directed to a storage holder, destined for placement in a liquid or foam dispenser.
- the invention is also directed to a liquid or foam dispenser.
- US2005/0006408 describes a storage holder destined for placement in a foam dispenser.
- the storage holder described in this publication consists of a liquid reservoir, a foam pump and a coupling piece.
- the liquid reservoir has an opening provided with a plug.
- the coupling piece connects the foam pump to the plug, wherein the foam pump is screwed to the coupling piece.
- the coupling piece in turn is provided with a connecting element to connect the storage holder to the foam dispenser.
- a disadvantage of the storage holder of US2005/0006408 is that it is difficult to accurately position the foam pump to the coupling piece by means of screwing. It is important that the outlet for foam of the foam pump and the means to connect the storage holder to the foam dispenser are correctly positioned relative to each other. If this is not performed accurately the outlet for foam may not be in its operational position once the storage holder is placed in the foam dispenser.
- the present inventions aims to provide a storage holder which does not have this disadvantage.
- the invention is directed to a storage holder, destined for placement in a liquid or foam dispenser, comprising a liquid reservoir, a pump and a plug extension,
- liquid reservoir has an opening, which opening is provided with a tubular plug which plug is provided with a cylindrical opening having an axis and which cylindrical opening fluidly connects the interior space of the liquid reservoir with the exterior of the liquid reservoir, which plug further has an outer surface having an oval cross-section at its end part extending from and facing away from the liquid reservoir,
- the pump is provided with a pump section and a tubular inlet part extending from the pump section and having a smaller cross section than the pump section, which tubular inlet part is fixed into the cylindrical opening of the plug by a clamping connection,
- the pump is provided with a female or male part and the plug extension comprises an opening for the pump and means to couple the storage holder to the liquid or foam dispenser and is connected to the outer surface of the plug by means of a snap connection or a clamping connection, and wherein
- the plug extension is provided with a female or male part suited to receive the respective male or female part of the pump such that a rotational displacement of the pump relative to the plug and plug extension is avoided.
- the invention is also directed to a liquid or foam dispenser comprising a housing and a storage holder according to the invention, wherein the storage holder is fastened to the housing with the means to couple the storage holder to the liquid or foam dispenser.
- the pump is not connected to a coupling piece as in the prior art design. Instead the pump is directly connected to the plug. Because of the oval outer surface of the plug and because of the presence of the female and male members an assembly results wherein the pump can only be positioned in a well- defined position or positions relative to the plug extension and to the plug. This simplifies the assembly of such a storage holder and avoids positioning issues when placing the storage holder in a foam or liquid dispenser.
- Figure 1 shows part of the storage holder according to the invention.
- Figure 2 shows part of another storage holder according to the invention.
- Figure 3 shows how the storage holder can be fastened into a dispenser
- Figure 4 shows the storage holder according the invention.
- the plug extension is provided with an opening for the pump.
- the opening in the plug extension is such that the pump can enter said opening and is suitably free to move in an axial direction within said opening.
- the plug extension is provided with a female or male part suited to receive the respective male or female part of the pump such that a rotational displacement of the pump relative to the plug and plug extension is avoided.
- a female or male part is suitably present in said opening of the plug extension.
- the plug extension comprises means to couple the storage holder to the liquid or foam dispenser. Such means may be surfaces present at the exterior of the plug extension and suited to couple the storage holder to a liquid or foam dispenser.
- the plug extension may be one structural part or be separate connected parts. The separate parts may be the means to couple the storage holder to the liquid or foam dispenser and the part connected to the plug. These separate parts may be assembled by for example a snap connection. The advantage of using separate parts is that the assembled storage holder can be easily adapted for different designs of liquid or foam dispensers. For example by adding the required surfaces at a later stage or by replacing already assembled surfaces with a different design of surfaces suited to couple the storage holder to another liquid or foam dispenser.
- the plug extension suitably has an end for connecting to the outer surface of the plug.
- the plug extension will have an oval formed opening which enables a clamping or snap connection with the outer surface of the plug.
- the plug extension is connected to the outer surface of the plug by means of a snap connection. Such a connection is advantageous because it avoids that the plug extension can disengage from the plug, even when a pulling force is exercised on the plug extension.
- a problem when using a clamping connection between the tubular inlet part of the pump and the cylindrical opening of the plug is that this connection may fail due to relaxation of the material of the plug. This especially occurs when the plug is made of a thermoplastic polymer, like polyethylene or polypropylene. These materials are however preferred because these materials are compatible with the materials typically used for the liquid containers. To avoid such relaxation it is preferred that at least part of the inner surface of the cylindrical opening of the plug where the inlet tube of the pump is fixed by a clamping connection is at the same axial position as where the plug extension is connected to the outer surface of the plug.
- a rim extending from the outer surface may be present for enabling such a connection. This rim will avoid or at least minimise relaxation at that axial position of the plug.
- the pump may be any liquid or foam pump provided it is provided with a pump section and a inlet tube extending from the pump section and having a smaller cross section than the pump section.
- Such pumps are well known for hand soap dispensers and hand foam dispensers as positioned on top of a bottle.
- the pump is suitably operated by the muscular energy of the operator or by means of an electro motor at the moment of use. It may be a liquid pump or a pump which combines liquid and air to create a foam.
- the pump is suitably a piston pump wherein the pump comprises a pump section comprising a moveable operating part comprising a liquid piston, an optional air piston and a nozzle for dispensing a liquid or foam and a fixed part comprising of the inlet tube fluidly connected to a liquid chamber and optional air chamber positioned around the liquid chamber, wherein the fixed part further comprises of a cap through which the nozzle extends from the liquid or foam pump and which cap has a larger cross section that the inlet tube and which cap has a side which may or may not rests on the plug extension .
- pumps are used which are manufactured in large series for use on top of bottles. Such pumps will be provided with a cap with which the pump can be fixed to the bottle.
- connection between the cap and bottle is typically achieved by means of a screw
- connection or by means of a snap connection.
- connection means In the storage holder according to the invention no use is made of such connection means even if they are present in the commercially available and used pumps.
- the pump may be a liquid pump or a foam pump.
- suitable liquid and foam pumps are described in US3359917, US5271530, EP0544549, US5443569,
- the pump is be provided with a male or female part and the plug extension is provided with a corresponding female respectively male part.
- Male and female part are such that when assembled the male part sits within the female part and avoids rotation of the pump relative to the plug extension.
- the plug extension is non-rotatably connected to the plug because of the oval outer surface of the plug. Thus also a rotational displacement of the pump relative to the plug is avoided.
- the pump is a foam pump.
- Such a foam pump suitably comprises a pump section comprising a moveable operating part comprising a liquid piston, an air piston and a nozzle for dispensing a foam and a fixed part comprising of the inlet tube fluidly connected to a liquid chamber and an air chamber positioned around the liquid chamber.
- the fixed part further comprises of a cap through which the nozzle extends from the liquid or foam pump and which cap has a larger cross section that the inlet tube.
- the pump is a foam pump it is preferred that air can be sucked in by the air piston.
- the plug extension is preferably provided with openings which fluidly connect the exterior of the storage holder with the inlet of the air piston. The opening of the plug extension suitably encompasses part of the inlet tube and part of the air chamber of such a foam pump.
- the liquid reservoir may be any container suitably to hold a liquid.
- the liquid reservoir is a reservoir having a flexible wall. This is advantageous because when liquid is discharged from the reservoir via the pump no replacement air is required to be added to the reservoir in order to avoid a vacuum.
- the reservoir having a flexible wall is preferably made of a thermoplastic polymer such as polypropylene or polyethylene.
- the plug has a tubular opening in which the inlet tube of the pump is fixed by a clamping connection.
- the exterior surface of the plug is suitably provided at its exterior with a rim having a larger diameter than the plug and wherein at least part of the inner surface of the cylindrical opening of the plug where the inlet tube of the pump is fixed is at the same axial position as the rim.
- the plug extension is connected by means of a snap connection it may be preferred to have at least two rims to be provided at the exterior of the plug.
- a first rim allows a snap connection with the plug extension and a second rim, located nearer to the fluid reservoir, avoids that these means further move towards said reservoir.
- the plug may also be provided with two extension surfaces extending radially outward at either side of the tubular body of the plug. These two surfaces are in one plane and form an anchor for the plug when connected with the flexible fluid reservoir.
- the plug and its extension surfaces are positioned in a larger opening of a reservoir having a flexible wall. By sandwiching the extension surfaces and tubular plug body within two surfaces of the flexible reservoir and welding the resulting sandwiched layers a closed reservoir may be obtained provided with the plug in the opening of the reservoir.
