2 Claims. (Cl. 215 '24) My invention relates generally to a non-refillable bottle and particularly to a novel arrangement and construction of the neck portion thereof whereby the same is sealed independently of 3 the cork or cap and permits unrestricted use of such conventional closure devices, and an im-' portant object of my invention is to provide a simple, efiicient, and inexpensive sealing means which once opened cannot be restored so as to enable spuriously refilling and re-sealing the bottle.

Another important object of my invention is to provide a destructible sealing, device of the character described which is composed of only three principal parts which are easily and inexpensively manufactured and are easily placed in the bottle neck in assembled sealing condition.

Other important objects of my invention will be apparent froma reading of thefollowing description in connection with the drawing, wherein for purposes of illustration I have shown a preferred-embodiment of my invention.

In the drawing:-

Figure 1 is a transverse vertical sectional view through the neck portion of a bottle showing the arrangement of the invention adapted thereto.

Figure 2 is a perspective View of the locking member.

Figure 3 is a perspective view of the frangible sealing member.

Figure 4 is a transverse vertical sectional view taken through Figure 3 showing the detachable portion in a depressed position.

Figure 5 is a perspective View of the perforated member.

Referring in detail to the drawing, the numeral 5 generally designates the neck of a bottle in which is seated the cork or other suitable closure generally designated 6, the closure being received in the cylindrical bore I.

The lower part of the bore indicated by the numeral 8 is of relatively reduced diameter so as to define the shoulder 9. At the lower end of the reduced part 8 of the bore the interior of the bottle adjacent the neck is formed with an annular right angular shoulder II].

Of approximately the same diameter as the upper and larger part of the bore I and seated on the shoulder 9 is the sealing disk-II which has a concentric circular cut I2 therein which is made on an angle as indicated in Figure 4 to produce the flap or tab I3. The material of the disk II is such that the part thereof which remains connected to the tab I3 provides a very flexible hinge for the tab I3. Diametrically opposite sides of the disk I I have the chordally arthe legs of the locking member.

ranged slots I4 and I5 to accommodate the legs of thelocking member to be described. The sealing diskmay be suitably made of rubber.

Seated on the top of the sealing disk II isthe perforated dome element which is generally dsthat of the disk ii. The'element I8 has at diametrically opposite points the 'chordally arranged slots it and ii to be registered with the slots I4] and, E5 of the sealing disk I I, and also tofreceive V The central por- 'tion of the element I8 is provided with a dome I9 ignated It, and which has a diameter similar to which is formed in its walls with perforations 2i].

Confined in the chamber defined by the interior of the dome I9 and the top of the disk II in cluding the tab I3, is the free ball 2! which is large enough to avoid falling into the bottle in any open position of the tab l3, yet large enough to have sufficient weight to push down the tab 43 from such an open position as is shown in Figure l, whenever the bottle is righted. The

dome and the locking member may be suitably made of aluminum;

Locking the dome element and the sealing disk II in place in the bottle is the locking'member which is generally designated 22 and includes the circular top plate which has a diameter approaching the diameter of the disk I I and the element I8. Diametrically opposite points of the plate 22 are inset as indicated by the numeral 22' and from these portions depend the locking legs 23 and 24 which have reduced lower portions defining the shoulders 25 and 25, and have curvedly upturned hooks 21 and 28 on their lower ends. The curvature of the hooks is such that they slide readily on the walls of the bore I and the lower bore portion 8 when the locking element is being pushed into position in the bottle. The height of the wide upper portion of the legs above theshoulders 26 and 2'! is the same as the height of the domeiQ above the upper surface of the plate I8 so that the shoulders bear against "the .upper'side of the dome II with the center of the plate 22 resting on the center of the top of the dome as indicated in Figure 1 when the locking element is in locking position. Engagement of the hooks 2'! and 28 under the right angular shoulders II] on the interior of the bottle securely locks the locking member in the bottle. Because of the fiat unbroken surface presented by. the top of the plate 22, no purchase is presented to any implement inserted in the mouth I of the neck of the bottle for the purpose of forciibly removing the locking device without damaging the same. Therefore, the bottlecannot be thereof will press upon the underside of the tab l3 with sufiicient force to open the same to a position such as that illustrated in Figure 4, so?

that the liquid may flow through the perforations 20 in the dome and throughthe inset portions 22' in the opposite sides of the plate 22, and then be poured from the mouth of the neck. When; the

bottle is righted, the tab [3 will exhibit a tendency to fall back into closed position, and this tendency 'will be materially aided by theweight; of

preferred embodiment of my invention, it is to be definitely understood that 'I do not desire tolimitf the invention thereto, and any change or changes, may be made in the materials, and iin'jthe struc-Z ture and arrangement of the parts, within the spirit of the invention and the scope of the sub-' joined claims. i s

Whatis claimed is:,-

1. In combination with the neck of ra bottle said neck being formed with a bore, a reduced lower portion of. said bore-defining a shoulder, a

sealing :disk having an upwardly opening closure and seatedon said shoulder and'closing said bore,

a concave-convex member seated on said sealing disk, a second disk seated on said concavo-convex member, legs depending from said second disk through openings provided in said member and in said sealing disk and depending within and engaging portions of the interior of the bottle, so as to anchor said disk and said' member in mutual engagement, and a free member disposed within said concave-convex member and resting on said closureof said first-mentioned disk.

'2. In combination with the neck of a bottle said neck being formed with a bore, a reduced lowerportion of said bore defininga shoulder, a the ball 2i thereon, which will efiectively close" the tab [3 so as to preserve the'con'ten't's of the bottle against exposure to the atmosphere. Although I have shown and described herein a v sealing disk having an upwardly opening closure so as to anchor said disk and said member in mutual engagement, and a free member disposed within said concavoconvex member and resting on said closure ofsaid first-mentioned disk, said concave-convex member being provided withper forations for the passage of liquid from the interior of said bottle.
