3 Claims.

This invention relates to container closures applicable to bottles or cans or the like, and has for its primary object improved means for easily Aand readily controlling the outlet of the conltainer in dispensing materials therefrom.

A further object of the invention is to provide a container closure which is of simple and economical construction, which positively seals the container when the closure is in closed position, which is positive in operation and which can be easily and quickly assembled.

Still further, the invention aims to provide novel means for latching the closure in either open or closed position and to also provide a `Z`container composed of a minimum of parts which may be marketed at a low cost.

Still further, the invention aims to provide a device of this type wherein the closure is moved to open position by sliding thereof axially of the Ycontainer and to further provide for substantially circular dispensing of the material in use.

The invention has further and other objects which will be set forth and manifested in the course of the following description.

In the drawing:

Figure 1 is a side elevation of the invention,

the container being shown in fragment;

Figure 2 is a section on line 2-2 of Figure 1;

Figure 3 is a section on line 3--3 of Figure 1;

Figure 4 is a view similar to Figure 2, showing the parts in dispensing position.

In proceeding in accordance with the present invention the container has a neck 1 which may be of cylindrical form and is provided with an inset portion 2 from which a dome 3 extends, the latter being tapered or inclined as shown at 4 and provided with dispensing orces or apertures 5. The dome preferably has a at top 6 as shown. The closure 7 slides axially of the dome and is of ring-like form and has an inclined outer portion 8 which, when the parts are in the position of Figure 2, closely engages the inclined part 4 of the dome so as to effectually seal the container.

i The closure is formed with a circular outwardly extending flange 9 which latter is preferably rolled to provide a bend 10, the latter affording a circular finger engaging member by means of which the closure can be slid from the position of Figure 2 to that of Figure 4, and vice versa. It will be noted that the flange 9 seats on the horizontal part 11 of the inset part 2 thereby to additionally seal the container against the ingress of air or moisture or the like. The dome 4 is provided with a pair of spaced inwardly struck (c1. zal-62) teats 12 forming keepers for engagement with corresponding teats 13 that are struck out from flaps 14 that are formed integral with the closure '7 and are located at diametrically opposite points on the latter. These flaps constitute catches that are flexible and which as shown in Figure 1 are formed by slits formed in the closure. For the purpose of preventing rotation of and for also restricting sliding movement of the closures relative to the dome, the latter is provided with elongated inwardly struck portions 15 which provide channels in which inwardly struck teats 16 on the closure 7 are freely slidable and which upon engagement with the ends of the channels provided by the elongated inwardly struck portions 15 restrict sliding movement of the closure accordingly.

In operation it will be seen that upon movement of the closure from the position of Figure 2 to that of Figure 4 the openings or apertures 5 will be uncovered whereby the material will egress therethrough and engaging the inclined parts 8 of the closure will be dispensed in a substantially circular formation.

What is claimed is:

1. In combination with a container neck having an inset portion provided with a circularV dome that has a tapered portion which is apertured and which has a flat closed top, a slidable closure on the dome having an open top and a tapered portion engageable with the tapered portion of the dome to seal the apertures of the latter, said closure having a flange engageable with the inset and having a circular finger-engaging part on the flange, a vertically channeled part formed in the dome, a member carried by the closure and extending into the channeled part to prevent rotary movement, and to restrict sliding movement of the closure, a flexible member carried by the closure and having a projection, and keepers carried by the dome to engage the projection whereby to latch the closure in both open and closed positions.

2. In combination with a container neck having a dome formed with an outer tapered part which is apertured and with a closed outer end, an axially slidable closure on the dome having a tapered part closely fitting that of the dome and having an open outer end, means to prevent rotation of and to restrict sliding movement of the closure on the dome including a channeled part on one of the last two named elements and a projection on the other of the two said elements engaged in the channeled part, a flexible catch on the closure having a projection and keepers on the dome for engagement with the projection of the catch.

3. In combination with a. container neck having a, dome formed with an outer tapered part which is apertured and with a. closed outer end, an axally slidable closure on the dome having a. part closely fitting that of the dome and having afi iloi
