UNITED STATES PATENT OFFICE 2,066,121v DIs'PENsING DEVICE Clarence P. Morris, Silver Spring, Md. `*Application November 26, 1935, Serial o. 51,691

' 2 claims. (o1. 215-73) My invention consists of improvements in dispensing devices it being in the nature of an adjustable telescopic drinking tube, detachable, which is confined within a bottle or ilask when the bottle cap or closure is attached, and so constructed that when thefclosure is removed the upper section of said tube will be forced, by means of an inclosed spring, to protrude beyond the mouth of said bottle or flask. 'Ihe lower section of said tube remains stationary and always suiliciently immersed in the liquid contents. toenable the user to' drink said contents as with an ordinary straw or drinking tube, except that it will not be necessary to handle the tube hereinafter described. Y v

One object of the invention is to provide an economical and practical dispensing device in the form of a telescopic drinking tube made of glass, cellulose, or other similar inexpensive material `which is impervious and immune from corrosion, disintegration, etc., when brought in contact with ordinary liquids.

Another -object of theinvention is to provide a supporting structure, made of cork and hard 25 rubber, through which the tube is placed and which when inserted in the neck of the bottle supports both the upper and lower sections of said tube.

Another object of the invention is to provide a sliding or adjustable section at the upper end of said tube which will be confined within the bottle or flask when the closure is attached and which will protrude beyond the mouth of the bottle when the closure is removed. 3 Another object of the invention is to provide a means of equipping bottles and flasks of the ordinary screw-cap and crimped-cap types with a sanitary removable drinking tube which may be changed from one bottle or flask to another as desired and used indefinitely. Y

Another object of the invention is to provide a drinking tube conned within the bottle or flask when sealed and telescoping beyond the mouth of said container when the closure is removed, the lower end of said tube remaining always sufficiently near the bottom of the container that the entire contents may be imbibed.

The form of the invention is more accurately 50 described and illustrated in the accompanying drawing wherein: l

Figure 1 is a View of a bottle of the screw-cap type showing, among other things, the closure attached so as to force the sliding section of the tube downward by compressing the spring,

until the bottle is sealed in the same manner as if the tube were not present.

Figure 2 is an enlargement of the upper p0r- .tion of the tube showing inmore accurate detail the sliding section, spring retainer and parts,

and the frustum effect moulded near'the lower end of said section.

Figure 3 is a view o f the tube asl a whole, without the bottle and screw-cap closure, showing the position of the sliding section of the tube when the lclosure is removed thereby allowing the spring to expand and force the upper end of said would bemade wherein the numerals indicatei I the metal portion of bottle cap; 2 the cork insulation underneath the bottle cap; 3 the cork insulation surrounding the spring-retainer housing; 4 the spring-retainer housing of hard rubber; 5 a flange near upper end of sliding section of tube to restrain the spring; 6 the enclosed spring; 'I the spring retainer; 8 the sliding section of tube; 9 a frustum moulded on sliding section, near lower end thereof; I0 a flange on lower end of spring retainer; II a ange on upper end of lower or stationary section of tube; I 2 a cork gasket; I3 a ange on lower end of sliding section; I4 the lower or stationary section of tube; I5 the bottle; I6 screws; I'I corrugated efect at lower end of tube; I8 the disklike closure at upper end of spring retainer.

It will be observed that the tube is held in place by a supporting structure composed of an outer layer of cork insulation 3 and an inner layer of hard rubber 4. The purpose of the cork insulation is tol protect the contents of the bottle or flask from the rubber which otherwise` would tend to give the liquid an unpleasant taste and odor. The rubber inner layer is provided because of its greater resiliency and durability. Through a vertical opening in the center of said supporting structure the lower section I4 of the tube is inserted and extends downward to the bottom of the bottle or flask. Flange I I is constructed with an opening in the center just large enough to admit the smaller ange I3 which is passed through said opening into the larger section of tube, being restrained by the cork gasket I2 from passing back through said opening when the closures I and 2 are removed from the bottle or flask and the spring 6 is released. The pressure exerted by the spring when the closure is removed brings flange I3 in contact with the cork gasket which in turn isv brought flush against flange II thereby sealing the joint or coupling between the two sections 8 and I4 of the tube thus forming a continuous tube from the bottom of thek bottle vor flask to and beyond the mouth of said container, permitting the contents to be imbibed as with a straw or the ordinary drinking tube.

It will be noted that the retainer 1 for the spring and sliding section of tube is also inserted into the vertical opening of said supporting structure so that flange I0 at the lower end of said retainer rests flush on flange II at upper end of stationary section of tube.

It will'be understood that the stationarysection I4 of the tube and the spring retainer I are forced into the vertical opening of said supporting structure with sumcient pressure to prevent the contents of the bottle or flask from seep- `ing into the retainer and spring thereby eliminat ing the possibility of rust or corrosion. y

It will be understood that frustum 9 when the bottle or flask is sealed will be forced into the opening at the center of flange I0 at the lower end of the retainer with such pressure as to pre- Vvent the liquid from seeping into said retainer and spring, again eliminating the possibility of yrust orr corrosion.

said tube may be resting on the bottom of the bottle or flask. i

Having thus fully described Vmy invention, what I claim as new and desire to secure by Letters :Patent is:

l. A dispensing device'substantially as herein described, comprising a. bottle or flask, a closure therefor, and a telescopic drinking `tube fitted within said bottle or flask by means of a. cylindrical structure vwhich serves as a coupler and `supports both the upper and lower sections of said tube, the lower section of which is stationary and extends downward from Within said cylindrical structure to the bottom of the bottle or flask, whereas the upper section is adjustable, being confined within the bottle or flask and said cylindrical structure whenthe closure is attached, and by means of an inclosed spring being forced to yprotrude beyond the mouth of said bottle or flask when the closure is removed.

2. A dispensing device substantially as herein described, comprising a bottle or flask, a closure therefor, and'a sectional telescopic'drinking tube fitted within said bottle or flask by means of a supporting structurel which serves as a coupler and supports the sections of said tube,.one

section being stationary and extending down ward 'tothe bottom of the bottle or flask, whereas one section is adjustable, being confined within the container and supporting structure when the closure is attached-and, by means of an inclosed spring, forced to protrude beyond the mouth 'of ysaid container when the closure is removed.
