Abstract
Abstract A protective closure device for fitting to the end of a gun case, to protect the muzzle and forward sight of the gun from dirt and impacts, is disclosed. The device comprises a resilient plastic cap having an internal ledge, within which is received the end of the sight guard sleeve of the gun case and a resilient plug. The plug has projections which pass through holes in the sleeve and are retained behind the ledge in the cap by interference fit and engagement with the ledge. The plug presents a closed end face to the gun muzzle, and with the cap, defines an air enclosure so that impacts of the muzzle of the plug end face are absorbed without shock by the resilient cushioning effect of the interfitted plug and cap.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
A gun case protective closure device comprising: a cap having a closed forward end and a peripheral skirt having at least one inwardly extending projection; a flexible sleeve integral with or attachable to the gun case, the forward end of which has peripherally spaced apertures adjacent thereto and is adapted to be snugly received within the skirt of said cap; a plug having a closed rear end and radially outwardly extending projections, the plug having a cross-sectional shape and size to be an interference fit within the sleeve received within the skirt of said cap; and the radially outwardly extending projections on the plug and the inwardly extending projection on the cap being adapted to interfit and to cooperate with the apertures in the sleeve on assembly of the closure device, thereby to retain the closure device in assembled relationship.
Claim 2
Dependent Claim
140 words
A gun case protective closure device comprising: a cap having a closed forward end and a peripheral skirt having at least one inwardly extending projection; a flexible sleeve integral with or attachable to the gun case, the forward end of which has peripherally spaced apertures adjacent thereto and is adapted to be snugly received within the skirt of said cap; a plug having a closed rear end and radially outwardly extending projections, the plug having a cross-sectional shape and size to be an interference fit within the sleeve received within the skirt of said cap; and the radially outwardly extending projections on the plug and the inwardly extending projection on the cap being adapted to interfit and to cooperate with the apertures in the sleeve on assembly of the closure device, thereby to retain the closure device in assembled relationship.
Claim 3
Dependent Claim
80 words
The closure device of claim 1 wherein the inwardly extending projection on the peripheral skirt of the cap comprises a peripheral shoulder extending substantially at right angles to the skirt and the face of which shoulder is presented toward the forward end, and the radially outwardly extending projections on the plug are adapted to be received through the apertures in the sleeve and forwardly of the shoulder of the cap, thereby to retain the closure device irreversibly in assembled relationship.
Claim 4
Dependent Claim
24 words
The closure device of claim 2, in which the plug has a forwardly extending peripheral skirt carrying said projections, and an open forward end.
Claim 5
Dependent Claim
59 words
The closure device of claim 3 in which the cap has a peripheral groove between the forward end wall and the peripheral skirt and extending forwardly of the forward end wall, the groove having a radial dimension to provide a snug fit for the forward end of the skirt of the plug and the forward end of the sleeve.
Claim 6
Dependent Claim
19 words
The closure device of claim 4 in which the cap and the plug are made of resiliently deformable material.
Claim 7
Dependent Claim
17 words
The closure device of claim 5 in which the cap and the plug are made of polyethylene.
Claim 8
Dependent Claim
28 words
The closure device of claim 6, in which the peripheral skirt of the plug is generally frustoconical in shape, the closed rear end being the small end thereof.
Claim 9
Dependent Claim
19 words
The closure device of claim 7, wherein the flexible sleeve comprises the sight guard element of the gun case.
