Description

Fresh-keeping cover

The invention provides a cover, in particular a cover with automatic pressing and compressible suction to be adsorbed on the rim of a food vessel to achieve an air-tight effect to keep food fresh.

Currently, there is a prior art that the applicant previously obtained ROC Patent Announcement No. M336758 for a simple fresh-keeping and microwave cover. Please refer to Figures 1 and 2. The cover 1 is a rigid body and is formed on the outer periphery. A cover edge 11, the inner periphery of the cover edge 11 is surrounded by a cushion 12 that is the same shape as the cover edge 11, with the cushion 12, although it can be tightly sleeved on the inner periphery of the cover edge 11 When the cover 1 is covered on the rim 131 of the vessel 13 of various specifications, the soft pad 12 can be compressed and sucked on the rim 131 of the vessel 13 of various specifications. However, the soft pad 12 and the cover 1 If the cover 1 is reused after use, the soft pad 12 is not removed from the inner periphery of the cover 1 for cleaning, so that the upper and lower edges 120, 121 of the soft pad 12 are in contact with the The seams between the cover bodies 1 are easy to contain dirt and dirt. If they are to be reused, it is not only easy to breed bacteria but also unsanitary.

Next, the industry has developed two prior art ROC Patent Announcement No. M363454 fresh-keeping caps. Please refer to Figures 3 and 4. The fresh-keeping cap 2 is slightly recessed in the center and a horizontal rib 21 is provided on the top of the center. Several ribs 22 and 221 are respectively provided on the outer periphery of the transverse rib 21 and the outermost periphery thereof to maintain the slightly concave shape of the fresh-keeping cover 2 so that the fresh-keeping cover 2 does not sink, and the outer edge of the fresh-keeping cover 2 extends Set a handle 23 with the same thickness and the same plane as the fresh-keeping cover 2 so that the bottom of the fresh-keeping cover 2 and the bottom of the handle 23 form On a flat surface, the handle 23 has a perforation 231 for hanging the fresh-keeping cover 2 or as a ventilation hole for microwave heating. but, When the fresh-keeping cover 2 is used, and as shown in Figure 4, the user's hand 3 holds the transverse rib 21 of the fresh-keeping cover 2, and the two sides of the fresh-keeping cover 2 hang down so that the front and rear ends respectively show a concave The arc opening 24 is not flat. When the fresh-keeping cover 2 is placed above the bowl opening 41 of the flat-mouthed container 4, the two sides of the fresh-keeping cover 2 will first contact the bowl opening 41 due to sagging. Between the concave arc opening 24 and the bowl opening 41, it is easy for a part of the internal air of the flat-mouth container 4 to be discharged, so that the internal pressure of the internal air in the flat-mouth container 4 is reduced, and then slowly slide from the hanging position on both sides to make the These concave arc openings 24 are formed flat, so that the fresh-keeping cover 2 fully contacts the bowl opening 41 of the flat-mouthed container 4. As a result, the internal space of the flat-mouthed container 4 is smaller when the flat-mouthed container 4 is pressed again, which is likely to cause the fresh-keeping cover 2 The adsorptivity of the lid 2 when pressed toward the inside of the flat-mouthed container 4 is worse.

Since the fresh-keeping lid 2 is in a flat state, and the food 42 contained in the flat-mouth container 4 must be lower than the bowl mouth 41, the contents of the flat-mouth container 4 are limited. Please refer to Figure 5, if the food 42 contained in the flat-mouth container 4 is higher than the bowl opening 41, when the fresh-keeping cover 2 is to be closed, the hand 3 faces the transverse rib 21 of the fresh-keeping cover 2 after pressing down , So that the fresh-keeping cover 2 itself is made of silicone material to easily contact the food 42, resulting in poor hygiene of the food 42.

Since the bottom of the fresh-keeping lid 2 and the bottom of the handle 23 form a flat surface, if the fresh-keeping lid 2 is to be closed on the bowl opening 41 of the larger flat-mouthed container 4, please refer to Figure 6, The food 42 inside the flat-mouth container 4 has a smaller capacity to reduce the food 42 inside the flat-mouth container 4, and it is easier to get the food 42, which not only makes the food 42 unhygienic, but also makes it easy to make the fresh-keeping cover 2 unsafe. The bottom and the bottom of the handle 23 are completely adsorbed on the inner edge of the bowl opening 41 of the flat-mouth container 4. When the fresh-keeping cover 2 is to be taken out, the hand 3 needs to be able to pivot the handle 23 many times, which is difficult to directly The absence of the fresh-keeping cover 2 is taken out with the hand 3, so it is necessary to improve it.

The purpose of the present invention is to solve the deficiencies and limitations of the existing two fresh-keeping lids. The present invention provides an automatic pressing and compressible suction force to be adsorbed on the rim of the food vessel to achieve an air-tight effect to keep the food fresh and convenient for use.
