Double wall applicator
First Claim
1. An applicator of resilient material comprising:
- (a) an applicator body with an opening adjacent the top thereof, said applicator body having a skirt depending downwardly below the applicator opening said skirt having resilient locking means adjacent the inside of the skirt top and adjacent the bottom of the skirt, said skirt being open at the bottom;
(b) a cup, within the skirt, said cup having resilient locking means adjacent the top and bottom thereof cooperating with the skirt locking means to provide fluid tight engagement between the top and bottom locking means with a major portion of the cup walls spaced apart from the skirt between the locking means so as to provide a fluid tight air chamber there between, the cup adapted to contain liquid which communicates with the applicator opening and wherein the interior of the cup is substantially entirely within the area of the skirt whereby the applicator can be assembled by fitting the cup upwardly within the open bottom of the skirt to engage the locking means.

Abstract
An applicator of resilient plastic material having a double wall construction, an air chamber between the walls and spacers in the air chamber is disclosed. The applicator is adapted to be pressed between the thumb and forefinger to dispense glue. The applicator has an applicator body comprising a shoulder, a dispensing opening in the shoulder and a downwardly depending skirt. A cup which is adapted to hold glue, particularly cyanoacrylate glue, is within the skirt and the top and bottom portions of the cup are in fluid tight engagement with the applicator body adjacent the top and bottom of the skirt. The cup fits within the skirt with its walls in spaced apart relationship with the skirt to provide an air chamber therebetween. The shape of cup walls and the opposed skirt generally conform to each other. A preferred embodiment includes friction elements on the outside of the skirt overlying at least a portion of the area covered by the spacers.

7. A two piece applicator constructed of resilient plastic material comprising:
-
(a) a first piece comprising a homogeneously integral, injection molded hollow applicator body having a shoulder with an elongated nozzle providing a dispensing opening therein and a skirt depending downwardly from the shoulder said skirt having resilient locking means adjacent the inside of the skirt top and adjacent the bottom of the skirt; (b) a second piece comprising a cup within the applicator body with the top of the cup in fluid communication with the dispensing opening, said cup having resilient locking means adjacent its top and its bottom for cooperating with the resilient locking means of the skirt and being in fluid tight engagement within the applicator body with a major portion of the walls of the cup within the applicator skirt; (c) a major portion of the applicator skirt being spaced from the walls of the cup between the locking means to provide an air chamber there between and wherein there is a general conformity in the shape of the walls of the cup with the opposed walls of the skirt; and (d) said cup having two diametrically opposed vertical rib spacers molded on the outside of the cup walls and extending into the air chamber to inhibit the walls of the cup from contacting the skirt within said air chamber said spacers extending upwardly from adjacent the bottom of the cup along a major height of the cup. - View Dependent Claims (8, 9, 10, 11)

12. An applicator of resilient plastic material comprising:
-
(a) a vertically elongated elliptical applicator body having a shoulder with a dispensing opening and a nozzle adapted for drop-wise application of adhesive in fluid communication with the dispensing opening, the applicator body having a skirt depending downwardly from said shoulder, said skirt having a bottom opening and resilient locking means adjacent the inside of the skirt top and adjacent the bottom of the skirt; (b) an elliptical cup fitted within the skirt bottom opening with its open end facing upwardly and in fluid communication with the applicator opening and forming fluid tight engagement with the resilient locking means of the skirt top and bottom by cooperation of resilient locking means adjacent the top and bottom of the cup with the resilient locking means of the skirt and wherein the walls of the cup and the skirt provide for an air chamber there between. - View Dependent Claims (13, 14, 15, 16)
