Description

[Detailed Description of the Invention] Purpose of the Invention Industrial Application Field The present invention relates to a lid for a glass container, such as a cap, whose outer diameter gradually decreases downward.

Conventional technology Conventionally, glass containers such as pots were used without lids for water or other beverages, and they usually did not have lids and were rarely used as containers for food or other items. . However,
Sometimes a lid is used, but in most cases it is simply a separate item placed over the mouth; there is also Japanese Utility Model Publication No. 57-35015, in which a special lid is attached to a plastic cup-shaped container. is attached to the mouth of the container from above.

Problems that the invention aims to solve: If a container such as a cup is accidentally knocked over, all the beverage will immediately spill out and stain the table or floor, and even if it contains non-liquid food, it will immediately pop out and make a mess. . Additionally, containers such as pots are inherently prone to chips and scratches at the mouth.

Among the conventional problems mentioned above, for the latter problem, there are proposals such as Utility Model Publication No. 8-8961 and Utility Model Publication No. 29-9278, etc., as a general problem not only for pot-shaped containers, but It is difficult to do so, and for the former, a lid that fits onto the mouth from above has been proposed, as in the above-mentioned Japanese Utility Model Publication No. 57-35015, but this lid easily comes off and is not suitable for protecting the mouth of a glass container. It's inappropriate.

In other words, conventional lids are fitted onto the mouth from above, but if the lid is fitted tightly and securely to protect the mouth, it would be difficult to open and close the lid, making it easier to open and close the lid. In this case, the fit of the lid to the mouth becomes loose, and the purpose of protecting the mouth is not achieved. Of course, when the lid is not on, the mouth cannot be protected. Conventionally, no suitable lid has been found for cup-shaped glass containers that solves the above-mentioned problems.

Means for Solving the Problems Constituent of the Invention The present invention has been made in order to make it possible to use a cup or the like as a hygienic storage container with a lid whenever necessary, and to solve the above-mentioned conventional problems. A fitting cylinder part with an inner circumferential surface having an inverted truncated cone-shaped profile into which a peripheral wall near the container mouth fits, and a fitting cylinder part that extends inwardly from the upper end of the fitting cylinder part to within the thickness of the container mouth wall. A mounting part consisting of a shelf protruding toward the front, a locking wall erected from near the inner edge of the shelf, and an engagement protrusion provided on the upper outer periphery of the locking wall, and an outer diameter dimension of the locking wall. The upper end of the fitting cylinder of the fitting part and the lid part, which consists of a locking cylinder having similar inner diameter dimensions, an engagement protrusion provided on the inner periphery of the upper part of the locking cylinder, and a top plate that closes the lower end of the locking cylinder. The present invention relates to a lid for a glass container such as a pot, which comprises a band-shaped hinge connecting the lower ends of a locking cylinder of the lid, and is entirely made of an elastic plastic material.

Function: With the lid of the present invention, the attachment part is inserted from the bottom of a pot, etc., with the lid open, and slid toward the mouth.
There is some resistance because the inner diameter of the locking wall of the attachment part is smaller than the outer diameter of the container mouth, but if the lower end of the locking wall exceeds the container mouth edge, the shelf part will touch the container mouth edge, and the fitting cylinder part will The attachment part is completely attached to the container by coming into close contact with the outer surface of the circumferential wall near the mouth of the container, and when the hinge is bent and the lid is pressed from above, the engagement protrusion on the inner surface of the locking cylinder of this part is attached to the attachment part. The lid is engaged beyond the engagement protrusion on the outer surface of the locking wall, and the lid is closed.

In other words, the lid of the present invention is attached to the mouth by inserting the attachment part into the bottom of the cup-shaped container and sliding the outer circumferential surface of the container upward, so that it is simply fitted from above. Unlike the lid, it does not easily escape, making it extremely effective in protecting the rim of the container. Further, the lid portion is closed by engagement of the engaging protrusion, has a high sealing property, and is easy to open. Therefore, when using the lid of the present invention, the cup-shaped container can be used not only as a beverage container, but also as a container for small items.
In addition to being used as general food containers, such as candy containers, they are also frequently used as packaging containers.

The diameter of containers such as pots for which the lid of the present invention is used gradually decreases toward the bottom. The shape and dimensions of the lid may be any shape as long as it can be inserted into and passed through the lid of the present invention from the bottom side.

Example The invention will be explained in detail with reference to the embodiments of the drawings.

Fig. 1 is a plan view of the lid of the present invention, Fig. 2 is a sectional view taken along the line A-A in Fig. 1, and Fig. 3 is a side view showing a partially cutaway side view of the lid of the invention attached to the tip. .

The lid of the present invention is made of an elastic plastic material and consists of a mounting part 4, a lid part 5, and a hinge 6. The fitting part 4 includes a fitting cylinder part 9 having an inner circumferential surface having an inverted truncated cone-shaped profile into which a peripheral wall 8 fits near the top opening part 7, and a fitting cylinder part 9 having an inner circumferential surface having an inverted truncated conical profile. It consists of a shelf 10 projecting inward within a range, a locking wall 11 erected from near the inner edge of the shelf 10, and an engaging protrusion 12 provided on the upper outer periphery of the locking wall 11. The lid portion 5 includes a locking cylinder portion 13 having an inner diameter that approximates the outer diameter of the locking wall 11;
Engagement protrusion 14 provided on the inner periphery of the upper part of the locking cylinder part 13
and a top plate 15 that closes the lower end of the locking cylinder part 13, and a tongue piece 16 for opening and closing the lid part is provided as required. The hinge 6 has a band shape and connects the upper end of the fitting cylinder part 9 and the lower end of the locking cylinder part 13.

To attach the lid of the present invention to a pot, the mounting part 4 is inserted from the bottom part 17 of the pot with the lid part 5 open. Since the locking wall 11 is erected from near the inner edge of the shelf 10, the inner diameter of the wall is smaller than the outer diameter near the tip opening. Therefore, when the wall reaches the peripheral wall 8 near the mouth, there is considerable resistance, but when this wall exceeds the container mouth 7, the inner surface of the fitting cylinder 9 and the lower surface of the shelf 10 meet the container mouth 7 and the surrounding wall in the vicinity. 8, the mounting of the mounting portion 4 is completed. This is because the profile of the portion of the container peripheral wall 8 corresponding to the fitting cylinder portion 9 is in the shape of an inverted truncated cone, and the inner peripheral surface of this portion is shaped and dimensioned to fit this portion.

The inner diameter of the locking cylinder part 13 of the lid is made similar to the outer diameter of the locking wall 11 of the mounting part, but normally the former is made slightly larger and the elasticity of the hinge 6 is used to adjust this. The lid part 5 is bent and placed on the folded attachment part 4, and pressed from above to engage the respective engaging protrusions 12 and 14 with some resistance to close the lid. In order to adjust the resistance during engagement, the engaging protrusions 12 and 14 are provided with a notch 18 as necessary, or are formed into several partial protrusions.

Since the lid of the present invention is connected with a hinge 6, there is no chance of the lid part 5 being lost, and when the lid is closed and the engaging protrusions 12 and 14 are engaged, there is a locking cylinder on the top surface of the shelf part 10. 13 The bottom surface is in close contact and the tip is completely sealed. The lid can be opened easily using the opening/closing tongue piece 16.

Effects of the invention With the lid of this invention, a regular cup can be used as a clever food container, a storage for small items, etc., and it can also be used as a regular cup if necessary, and there are many lids that can be opened and closed. It is extremely convenient because it can withstand repeated use and the lid does not fall off or get lost. In addition, the lid of the present invention can be almost completely sealed, so even if the container falls over, the lid will remain closed and the contents will not spill out, making it especially hygienic when filled with food.

In addition, since the mounting portion of the lid of the present invention is tightly fitted to the mouth of the container such as a pot, it will not come off, and this portion will be prevented from chipping or being scratched, thereby increasing its durability. Furthermore, by freely selecting the color of the lid of the present invention, it is possible to improve the design value of containers such as pots.
