Definitions
- the present invention relates to tube containers having shoulder portions that have a barrier unit that has a low absorption for antibacterial compounds, and in particular for aromatic group containing antibacterial compounds.
- the barrier unit can be a three dimensional insert, a film attached to the inner surface of the tube shoulder/ nozzle portions or an inner layer of a co-injection molded tube shoulder/ nozzle.
- Tube containers are used to hold and to dispense a wide range of products. These include adhesives, lubricants, lotions, medicants, shampoos, hair dressings, and various oral care products. Some of the lotions, medicants and oral care products contain an antibacterial compound. A problem with such products is that the antibacterial compound may be absorbed or otherwise degraded by the tube materials. The result is that the tube structure needs to be modified to reduce or to eliminate the absorption by the tube structure for the antibacterial compound. In many cases, and especially for oral care products, it is desirable also to reduce the absorption of the tube structure for other contained substances such as flavors and fragrances. Some package materials absorb flavor and fragrance components in an inappropriate ratio depending on the flavor and fragrance molecules. Thus the flavor or fragrance is changed. This problem needs to be solved for flavors and fragrances to preserve the taste and olfactory properties of the products.
- barrier materials have been used to reduce the loss of flavors or fragrances, and in some instances antibacterial compounds. It is widely believed in the industry that a good barrier to flavors and to fragrances is also a good barrier to antibacterial compounds, and that barrier improvement would be similar for all of these organic compounds.
- the barrier layer is normally selected based on the flavor or fragrance barrier properties.
- shoulder/ nozzle refers to the shoulder and nozzle as one part or as two separate parts. The shoulder/ nozzle, however, poses most of the problems because the shoulder and nozzle are relatively thick compared to the remainder of a tube. This is needed to maintain the mechanical strength of the tube.
- poly olefins are usually used as the material for the shoulder/ nozzle.
- This problem is thought to be solved for flavors by the use of an insert which is a material that has a very low absorptivity for the flavor components.
- This insert can be an interference fit into the top part of the tube, a film layer onto the inner surface of the tube or a layer co-injection molded onto the inner surface of the shoulder and nozzle.
- Tube containers are comprised of a tube body and a tube shoulder/ nozzle.
- the tube body usually is of a laminate structure and the tube shoulder/ nozzle of an alkene polymer containing plastic. These usually are poly ethylenes and poly propylenes.
- the tube body will be crimp sealed at the bottom after filling.
- the tube shoulder/ nozzle will be injection molded and attached to the tube body or compression molded and directly attached to the tube body. While the degree of absorption of an antibacterial can be readily controlled in the body of the tube by an appropriate multi-layer laminate structure this is not the case with regard to the shoulder/ nozzle.
- the aromatic group containing antibacterial compounds such as triclosan [5-chloro-2-(2, 4-dichlorophenoxy)phenol] are absorbed at a low level in injection molded shoulder/ nozzle parts of a tube container if a barrier unit of a copolymer of acrylonitrile and methylacrylate, a polyethylene naphthalate polymer or a polytrimethylene naphthalate polymer is used.
- the barrier unit can be a three dimensional insert, a film layer attached to the inner wall of the shoulder/ nozzle or a co-injection molded layer on the shoulder/ nozzle.
- the shoulder/ nozzle can be solely of these materials.
- the copolymer of acrylonitrile and methacrylate can have an acrylonitrile content of about 70% to about 80% and a methacrylate content of about 20% to about 30%.
- a shoulder/ nozzle barrier unit the absorption of triclosan by the shoulder/ nozzle can be reduced to less than about 10 mg/dm 2 , preferably less than 5 mg/dm 2 , and most preferably less than 1 mg/dm 2 for a dentifrice containing about 0.3% triclosan.
- the absorption can be more than 20 mg/dm 2 when a barrier unit made from currently used flavor barrier materials such, as polyethylene terephthalate or polybutylene terephthalate, are used. It can range higher when other polymers with barrier properties are used.
- barrier unit is a polyethylene naphthalate polymer or a polytrimethylene naphthalate polymer the absorptivity for antibacterial compounds can be considerably reduced if the polymer has been biaxially oriented.
- Such barrier units will usually be in the form of a film. If films of these polymers are to be used polymers are to be used the biaxially oriented version is preferred.

If a copolymer of acrylonitrile and methacrylate the acrylonitrile content can be from about 70% to about 80% with the remainder primarily being methacrylate.
- the barrier unit 30 can be injection molded to produce barrier units that maintain their dimensions and do not have any micro-cracks that would permit the substance to be dispensed from the tube from contacting the shoulder/ nozzle 14/16 wall inner surface.
- Figure 3 is a cross-section of the tube 10 shoulder/ nozzle 14/16 with a barrier unit 32 in place.
- This barrier unit is of a polymeric film construction that has a low absorptivity for antibacterial compounds, and in particular for aromatic group containing antibacterials such as triclosan.

- the barrier film 32 can be attached to the inner wall of the shoulder/ nozzle 14/16 at the time that the shoulder/ nozzle is being formed and attached to the wall of the tube body 12.
- the barrier film cut to the appropriate shape will be placed on the mandrel of the mold and be attached to the plastic of the shoulder/ nozzle 14/16 as the shoulder/ nozzle is being formed and attached to the tube body.
- the barrier polymer will be adjacent to the substance to be dispensed.
- Figure 4 is a cross-section of the tube 10 shoulder/ nozzle 14/16 with a barrier unit 34 in place.
- the barrier polymer comprising the barrier unit 34 is co- injection molded with the shoulder/ nozzle 14/16 polymer which is an alkene polymer such as a polyethylene or polypropylene.

- Figure 16 is a graph of the absorption of triclosan by a high density polyethylene shoulder/ nozzle of a tube.
- the product is Colgate Total Whitening Plus gel dentifrice which has a triclosan content of 0.3%.
- the test is conducted by having tubes having a diameter of 28 mm containing 114 gms of tooth gel being maintained within a temperature chamber maintained at 40 0 C for the times set out in the graph of Figure 5. Tubes are removed at 10 day intervals and the shoulder/ nozzles tested for triclosan adsorption. It is seen that more than 20mg/dm 2 of triclosan has been absorbed by the polyethylene shoulder in a period of 40 days.
- Figure 17 is the graph of the absorption of triclosan by a polyethylene terephthalate three dimensional barrier unit as illustrated in Figure 2. The same test procedure as that for the above polyethylene shoulders was used. The dentifrice was Colgate Total Whitening Plus gel containing 0.3% triclosan. The data on the graph shows that after 40 days at 40 0 C more than 30mg/dm 2 of triclosan has been absorbed by the polyethylene terephthalate barrier unit.
- Figure 18 is a graph that gives the data for the absorption of triclosan by a polyethylene naphthalate amorphous barrier unit film as illustrated in Figure 3.
- the film could be in both the shoulder and nozzle or only the shoulder. More absorption will occur in the shoulder due to the larger surface area of the shoulder.
- the same test procedure as for the polyethylene shoulders was used.
- the dentifrice was Colgate Total Whitening Plus gel containing 0.3% triclosan. After 40 days at 40°C the polyethylene naphthalate has absorbed less than 5 mg/dm 2 . This is less than a polyethylene shoulder and less than a polyethylene terephthalate barrier unit.
- Figure 19 is a graph that gives the data for the absorption of triclosan by a acrylonitrile/methacrylate copolymer three dimensional barrier unit as described in Figure 2.
- the same test procedure as for the polyethylene shoulders was used, The dentifrice was Colgate Total Whitening Plus gel containing 0.3% triclosan.
- the acrylonitrile/methacrylate copolymer After 40 days at 40 0 C the acrylonitrile/methacrylate copolymer also has absorbed less than 0.5 mg/dm 2 . This, like polyethylene naphthalate, is less than a polyethylene shoulder and less than a polyethylene terephthalate barrier unit.
- test samples were prepared as set in the description of each sample in the description of the particular graph.
- the dentifrice containing 0.3% triclosan was in intimate contact with the surface of the test sample for the given time period. Depending on the test sample 3.5 gms to more than 50 gms were used. Some of the samples were taken from the oven in 20 day intervals and analyzed. Occluded dentifrice was removed from the sample surface by wiping and the surface rinsed with water to remove all occluded dentifrice. After surface drying defined surface areas were cut from each of the samples and each sample extracted with dichloromethane. Extraction was by immersion in the dichloromethane for 24 hours at 40 0 C.
- test results are given in the amount of triclosan absorbed by the milligrams of triclosan that is absorbed by a given area of the sample polymer at 40 0 C at 10 day intervals for 90 days.
- the early work on the samples of Figures 16 to 19 was conducted for 40 days with later work extending to 90 days.
- 40 days at 40 0 C in general, an equilibrium will be reached where the absorption of triclosan and the desorption of triclosan will be in equilibrium. This validates the early work.
- a temperature of 40 0 C is the typical highest temperature that a dentifrice will experience for an extended period of time.
- the substance from which the triclosan is absorbed is the Colgate Total White gel dentifrice which has a triclosan content of 0.3%.
- the more valuable data is the comparison data. That is, the comparison of the data from polyethylene naphthalate and polytrimethylene polymers and acryloniyrile/methacrylate copolymers with the date high density polyethylene (HDPE), medium density polyethylene (MDPE), amorphous polyethylene terephthalate, and polybutylene terephthalate.
- HDPE and MDPE are common shoulder and nozzle material.
- Polyethylene terephthalate, and polybutylene terephthalate are known barrier materials for flavor oils and related substances. Nylons also are known barrier materials for various substances.
- Acryloniyrile/methacrylate copolymers have triclosan barrier properties that are about 60 times better than polyethylene terephthalate polymers and about 40 times better triclosan barrier properties than polybutylene terephthalate two well known barrier materials.
- Amorphous polyethylene naphthalate has barrier properties about 4 times better than polyethylene terephthalate with biaxially oriented polyethylene naphthalate having barrier properties of more than 100 times that of polythylene trerphthalate.
- barrier unit comprised as a three dimensional, film or co-injection molded layer barrier unit of polytrimethylene naphthalate polymer, polyethylene naphthalate polymer or acrylonitrile/methacrylate coploymer. Barrier units comprised of these materials will limit the loss of triclosan in the formulation by the adsorption of the triclosan by the materials of the shoulder/ nozzle of the tube.
- biaxially oriented polyethylene naphthalate and a biaxially oriented polytrimethylene naphthalate have a significantly lower absorption for triclosan than each of these polymers in a non-biaxially oriented version.
- These polymers and copolymers have a significantly lower absorption for triclosan than the range of other polymers that have been tested as shown in the graphs.
